Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] This application claims the benefit of priority under 35
U.S.C. .sctn.119(e) of U.S. Provisional Application No. 61/794,163
filed Mar. 15, 2013, the disclosure of which is hereby incorporated
by reference in its entirety.
TECHNICAL FIELD
[0002] The subject matter of the present disclosure relates to case
structures, and more particularly, to case structures providing
waterproof or water-resistant capabilities.
BACKGROUND
[0003] A number of portable electronic devices advantageous for
handheld operations have been developed, such as Apple's
iPhone.RTM., various generations of Apple's iPad.RTM., various
generations of Samsung's Galaxy.RTM. phone devices, Galaxy.RTM.
series tablets, Android.RTM. tablets, tablet PCs, smart phones,
other touch-panel devices, digital cameras, camcorders, e-readers,
various generations of Kindle.RTM., various generations of
Nook.RTM., and many other devices. The development of these
electronic devices has provided useful functions for daily life and
business.
[0004] Many portable electronic devices are not waterproof.
However, portable electronic devices may often be required to
operate under conditions or in environments that may increase the
possibility of physical impact, water/moisture/dust damage,
temperature effects, etc. The operating or environmental conditions
may therefore affect portable electronic devices' reliability and
operability. Thus, a measure to provide some level of
shock/drop/impact-, water-, dust-, and/or chemical-resistance
and/or other forms of protection may be desired to protect portable
electronic devices or improve their operability or reliability
under various operating conditions.
[0005] Some commercially available cases for protecting electronic
devices may offer certain level of protection, with some of them
conforming to the IPX5 water-resistance standard defined in the
International Electrotechnical Commission (IEC) document No. 60529.
Generally, cases that conform to the IPX5 water-resistance standard
may be limited to protection of the enclosed devices against water
jets of prescribed characteristics. For example, some cases may
protect enclosed devices against water projected at all angles
through a 6.3 mm nozzle at a flow rate of 12.5 liters/minute and a
pressure of 30 kPa for at least 3 minutes from a distance of 3
meters. However, the cases may not protect devices operated under
different conditions.
[0006] Some cases, while providing protection above the IPX5
standard, may have large dimensions, turning portable devices into
bulky and less-convenient devices. Some other cases prevent the
operation of portable electronic devices when enclosed in the
cases, making underwater or other operations impossible.
[0007] With regard to the above-mentioned conditions, some
protecting structures for smart phones or tablet PCs have been
developed, such as a combinable case structure or a bag-type
shield. A combinable case structure, in some circumstances, may be
better than a bag-type shield and may be widely used. However, it
may be desirable to provide protective casings that may provide one
or more of water-resistance, ease of operability, underwater
operations, impact absorption, enhanced structural strength, and
acceptable dimensions or portability.

DETAILED DESCRIPTION
[0038] The aforementioned and other aspects, solutions, and
advantages of the presently claimed subject matter will become
apparent from the following descriptions and corresponding
drawings. The described embodiments may further clarify the
presently claimed subject matter and shall not be construed to
limit the scope of the presently claimed subject matter.
[0039] The detailed description may include specific details for
illustrating various aspects of case structures for portable
electronic devices. However, it will be apparent to those skilled
in the art that the disclosure may be practiced without these
specific details. In some embodiments, well-known elements may be
shown in block diagram form, or omitted, to avoid obscuring the
inventive concepts presented throughout this disclosure.
[0040] As an example, various aspects of a case structure may be
illustrated by describing components that are coupled or connected
together. However, the disclosure, while using Apple iPhone 5.RTM.
and Apple iPad.RTM. mini devices, as illustrations, may be
practiced with other portable electronic devices. As used herein,
the terms "coupled" and "connected" may be used to indicate either
a direct connection or coupling between two components or, where
appropriate, an indirect connection or coupling to one another
through intervening or intermediate components. In contrast, when a
component is referred to as being "directly coupled" or "directly
connected" to another component, there may be no intervening
elements.
[0041] Relative terms such as "lower" or "bottom" and "upper" or
"top" may be used herein to describe one element's relative
relationship to another element illustrated in the drawings. It
would be apparent to those skilled in the art that relative terms
are intended to encompass different orientations of a portable
electronic device placed within a case structure in addition to the
exemplary orientation depicted in the drawings. As an example, if a
case structure for a portable electronic device in the drawings is
turned over, flipped, and/or rotated, elements described as being
on the "bottom" side of the other elements may then be oriented on
the "top" side of the other elements. The term "bottom" may
therefore encompass both an orientation of "bottom" and "top"
depending on the particular orientation of the case structure.
[0042] Various aspects of case structures may be illustrated with
reference to one or more exemplary embodiments. As used herein, the
term "exemplary" means "serving as an example, instance, or
illustration," and should not necessarily be construed as preferred
or advantageous over other embodiments of a case structure
disclosed herein.
[0043] FIG. 1A illustrates a perspective view of an exemplary case
structure 1000. FIG. 1B illustrates an exploded view of case
structure 1000 of FIG. 1A. Referring to FIGS. 1A and 1B, case
structure 1000 is provided for housing or enclosing a portable
electronic device (not shown), such as an Apple.RTM. iPhone 5
device, and therefore enables preventing or reducing of the
likelihood of shock/drop/impact-, water-, dust-, and/or
chemical-damage of the portable electronic device. Case structure
1000 may be substantially waterproof, such as waterproof in
compliance with class IP68 according to the U.S. National
Electrical Manufacturers Association rating. The types of portable
electronic devices that are capable of being enclosed in case
structure 1000 may include, but are not limited to, a cell phone, a
smart phone, an MP3 player, a portable computer, and a tablet PC, a
personal digital assistant, and/or other similar portable
electronic devices.
[0044] Referring to FIGS. 1A and 1B, according to some embodiments,
case structure 1000 may include a bottom cover 1, a first frame 2,
a film 3, and a second frame 4. In some embodiments, second frame 4
may be detachably coupled to or integrated with first frame 2 so as
to form a single piece. Film 3 may be coupled to one or both second
frame 4 and first frame 2 and be placed between the two frames. In
some embodiments, first frame 2 may be detachably coupled to bottom
cover 1. The dimensions and aspect ratios of bottom cover 1 and
second frame 4 may be substantially the same or similar. In some
embodiments, the dimension of first frame 2 may be substantially
similar or slightly smaller than bottom cover 1 and/or second frame
4 so that it may be coupled to or accommodated by bottom cover 1
and second frame 4. Referring to FIG. 1A, case structure 1000 is
illustrated in an assembled condition, and thus, some elements of
case structure 1000 may not be marked or labeled in FIG. 1A.
[0045] The material of case structure 1000 may include
polypropylene (PP), polycarbonate (PC), thermoplastic polyurethane
(TPU), or any other material having similar characteristics. As an
example, in some embodiments, the material of bottom cover 1 may
include polypropylene; the material of first frame 2 may include
polycarbonate; and the material of second frame 4 may include
thermoplastic polyurethane. One of ordinary skill in the art would
appreciate that the material of each element of the case structure
1000 may not be limited to those described above and may include
any other material desired. For example, the material of some
elements of case structure 1000 may include metal, alloy, stainless
steels, nylons, hard plastics, iron, aluminum, lead, and/or other
materials having similar characteristics, or any combination
thereof.
[0046] FIG. 1C illustrates a partial cross-sectional view of case
structure 1000 of FIG. 1A. FIG. 1D illustrates a partial, enlarged
cross-sectional view of case structure 1000 of FIG. 1A. Referring
to FIGS. 1B, 1C, and 1D, bottom cover 1 may include a housing 11.
In some embodiments, housing 11 may include a flat structure, such
as a flat bed, configured to accommodating or housing a portable
electronic device, such as an Apple iPhone.RTM. 5 device. The
dimensions of housing 11 may correspond to the structure and/or
dimensions of the portable electronic device, and may not be
limited to those illustrated in FIGS. 1B-1D. In some embodiments,
bottom cover 1 may include a groove 14 surrounding at least a
portion of the periphery of housing 11. Groove 14 may be formed by,
for example, a water barrier 13 and the internal peripheral portion
of bottom cover 1. In some embodiments, first frame 2 may have a
convex portion 20 corresponding to groove 14. When case structure
1000 is closed, convex portion 20 of first frame 2 may be partially
or entirely inserted or disposed in groove 14. One of ordinary
skill in the art would appreciate that groove 14 may be included in
other places. As an example, in some embodiments, groove 14 may be
included in first frame 2 or second frame 4. Correspondingly, in
these embodiments, convex portion 20 may be included in the
opposing frame or cover, such as bottom cover 1.
[0047] Referring to FIGS. 1C and 1D, in some embodiments, groove 14
may include a first coupling portion 141 on the side that is
further away from housing 11. For example, first coupling portion
141 may be included in the peripheral portion of bottom cover 1.
Groove 14 may also include a plurality of second coupling portions
142 on the side that is close to or near housing 11. For example,
second coupling portions 142 may be included in water barrier 13.
In some embodiments, second coupling portions 142 may be separately
or discontinuously disposed between groove 14 and housing 11, such
as disposed in water barrier 13.
[0048] Referring to FIGS. 1C and 1D, in some embodiments, convex
portion 20 of first frame 2 may include at least one first coupling
element 201 and a plurality of second coupling elements 202,
corresponding to first coupling portion 141 and second coupling
portions 142, respectively. In some embodiments, when case
structure 1000 is closed, and therefore convex portion 20 is in
contact with or inserted into groove 14, first coupling element 201
and second coupling elements 202 may be hingedly, rotatably,
movably, permanently, detachably, latchably, and/or snugly coupled
or engaged with first coupling portion 141 and second coupling
portions 142, respectively. First coupling element 201, second
coupling elements 202, first coupling portion 141, and second
coupling portions 142, may thus form of a water-sealing or
water-resistant structure configured to provide water-resistant or
waterproof capability to case structure 1000. As an example, first
coupling portion 141 and first coupling element 201 may each
include a protrusion that may be engaged with each other to form a
tight coupling. As another example, second coupling elements 202
may include a plurality of separated protrusions so that they may
be engaged with a corresponding plurality of second coupling
portions 142, such as a plurality of slots or small openings.
Moreover, in some embodiments, the protrusions of second coupling
elements 202 may be semi-circle shaped, so that a user may be
provided with a smoother and more convenient experience for
attaching and/or detaching of case structure 1000. One of ordinary
skill in the art would appreciate that to form a water-sealing or
water-resistant structure, some but not all first coupling element
201, second coupling elements 202, first coupling portion 141, and
second coupling portions 142 may be needed.
[0049] Referring to FIGS. 1C and 1D, water barrier 13 may further
include a plurality of protrusions 162 configured to enhance the
strength of water barrier 13. As an example, FIGS. 1C and 1D
illustrate that the plurality of protrusions 162 may include one or
more triangular-shaped fins configured to provide additional
support and structural strength to water barrier 13, so that the
likelihood of breaking, distorting, fracturing, chipping, bending,
and/or other similar damages may be prevented or reduced.
[0050] Referring to FIGS. 1C and 1D, case structure 1000 may
include a seal strip 5 configured to provide additional
water-sealing or water-resistance capability of the water-sealing
or water-resistant structure that includes groove 14 and convex
portion 20. Additionally, seal strip 5 and the water-sealing
structure, which may include one or more of first coupling element
201, second coupling elements 202, first coupling portion 141, and
second coupling portions 142, may also provide protection of the
enclosed portable electronic device from being damaged by water,
shock, dust, oil, mud, snow, vibration, spill, drop, impact, heat,
frost, acid, chemical, corrosion, rain, sand, and/or other forms of
intrusion. In some embodiments, seal strip 5 may be disposed within
groove 14 and in contact with convex portion 20 when case structure
1000 is closed. In addition, seal strip 5 may also provide
buffering or cushioning so that it may reduce or prevent the
likelihood of damage at the coupling area of bottom cover 1 and/or
first frame 2. In some embodiments, the material of the seal strip
5 may include silicone, rubber, thermoforming plastics,
polyvinylchoride materials, polycarbonate, polyethylene
terephthalate (PET), poly methyl methacrylate acrylic (PMMA),
adhesive tape, and/or any material having similar characteristics.
Seal strip 5 may be formed, for example, by a molding
processing.
[0051] FIG. 1E illustrates a partial, perspective view showing the
bottom side of case structure 1000 of FIG. 1A. Referring to FIGS.
1B and 1E, in some embodiments, a bottom side 21 of first frame 2
may include a first connection opening, such as an opening 22, a
second connection opening, such as opening 23, and an opening 24.
Opening 22 and opening 23 may be placed, for example, corresponding
to the positions of an earphone jack and a charging and
communication connector of the portable electronic device,
respectively. Therefore, when the portable electronic device is
accommodated, housed, or enclosed in case structure 1000, opening
22 and opening 23 may enable a user to operate the earphone
function and the charging and communication functions of the
portable electronic device without the need to remove the portable
electronic device from case structure 1000. Bottom side 21 may also
one or more audio holes (not shown) corresponding to the speaker
and the microphone of the portable electronic device. The audio
holes will be describes corresponding to FIG. 3E.
[0052] Referring to FIGS. 1B and 1E, in some embodiments, case
structure 1000 may further include a resealable portion 6
configured to improve or enhance the waterproof or water-resistant
capability of case structure 1000. For example, resealable portion
6 may be pivotally coupled to bottom side 21 of first frame 2
through an axis 26. In some embodiments, axis 26 may be placed,
such as inserted into, in a base connector 25, which may be
detachably or integrally attached to first frame 2 and/or second
frame 4. As an example, base connector 25, such as a hinge, may be
rotatably integrated with first frame 2 to form a single integral
piece.
[0053] Referring to FIGS. 1B and 1E, resealable portion 6 may
rotate toward first frame 2 and enclose bottom side 21. In some
embodiments, resealable portion 6 may include a resealable cover 61
corresponding to opening 23. When resealable portion 6 is coupled
to bottom side 21, resealable cover 61 may at least be partially
plugged or inserted into; or may cover, opening 23, so that it
enhances or improves the waterproof, water-resistant and/or the
dust-resistant capability of case structure 1000.
[0054] Referring to FIGS. 1B and 1E, in some embodiments,
resealable portion 6 may further include an opening 62
corresponding to opening 24 of first frame 2. For example, when
resealable portion 6 is coupled to bottom side 21 of first frame 2,
a securing mechanism 7 may be provided and configured to secure
case structure 1000. In some embodiments, securing mechanism 7 may
pass through opening 62, and couple to (or secure with) opening 24.
As an example, securing mechanism 7 may be a screw having threads
corresponding to the threads of opening 62 and/or opening 24, so
that securing mechanism 7 may couple resealable portion 6 to bottom
side 21 by the screw threads. Thus, securing mechanism 7 may be
configured to enable or enhance the coupling of resealable portion
6 and first frame 2, thereby providing further waterproof or
water-resistant capability of case structure 1000. One of ordinary
skill in the art would appreciate that the exemplary securing
structure that includes one or more of securing mechanism 7,
resealable portion 6, and first frame 2 are for illustration
purpose; and any other similar securing structures may be provided
for securing case structure 1000. For example, in some embodiments,
securing mechanism 7 may include no screw threads. Instead, by
adjusting the relevant sizes of securing mechanism 7 and opening
24, securing mechanism 7 may be snugly or tightly attached or
coupled to opening 24 without the need of screw threads. As another
example, securing mechanism 7 may include magnetic coupling
elements.
[0055] Referring to FIG. 1B, in some embodiments, at least a
portion of film 3 may be disposed on or couple to first frame 2 and
is configured to enable a user to view and operate an enclosed
portable electronic device. In some embodiments, film 3 may include
materials such as thermoforming plastics, polyvinylchoride
materials, polycarbonate, polyethylene terephthalate (PET), poly
methyl methacrylate acrylic (PMMA), adhesive tape, and/or any other
materials having similar characteristics. Film 3 may be flexible
but also may have an enhanced strength so that it may withstand
water pressure under a higher water resistance standard. As an
example, film 3 may be capable of withstanding a condition that is
specified in the IPX7 standard, i.e., a water immersion for at
least 30 minutes at a depth of at least 1 meter. Film 3 may also be
capable of withstanding a condition of a higher IPX8 standard,
i.e., a continual submersion in water under conditions which are
identified by the manufacturer. As another example, film 3 may also
be capable of withstanding the IP68 standard.
[0056] Film 3 may also be a clear/transparent or substantially
clear/transparent water-resistant film so that a user can view the
screen or a substantial portion of the screen of the portable
electronic device. In addition, film 3 may also enable a user's
operation of the portable electronic device when it is enclosed in
case structure 1000. For example, some portable electronic devices
may have capacitive-type touch sensors that are incorporated in the
touch-point screens. A user may operate these portable electronic
devices by touching and/or moving on the surface of the touch-point
screen. Film 3 may thus be a touch-sensitive or transmissive film
that enables the user to operate a touch-point screen of the
portable electronic device through film 3. This may permit
operations to be carried out without opening case structure 1000.
In other words, film 3 may enable the portable electronic device to
be operated when it is immersed under water or under other
conditions that require the portable electronic device to be
enclosed. One of ordinary skill in the art would appreciate that
film 3 may also be other types of films that can enable operation
of the portable electronic device, such as resistance-sensitive
films.
[0057] In some embodiments, film 3 may also be an anti-reflection
film, an anti-glare film, an anti-fingerprint film, a monitor
filtering film, etc. For example, film 3 may filter out the light
reflected from the smooth glass surface of the touchscreen device
as well as the radiation emitted from the portable electronic
device. This may be used to protect the user privacy by decreasing
the viewing angle of the screen of the portable electronic device.
In addition, film 3 may also be able to dissipate static electrical
charge buildup. Film 3 may also be polarized, colorized, or tinted,
depending on the application.
[0058] A portable electronic device may have buttons or switches,
such as the "home" button on an Apple iPhone 5.RTM. device.
Therefore, in some embodiments, film 3 may include a corresponding
convex or concave shape to enable convenient operation of the
portable electronic device. As an example, for an Apple iPhone.RTM.
5 device, film 3 may include a concave circle near the bottom edge
(not shown) for operating of the "home" button. One of ordinary
skill in the art would appreciate that the concave circle may be
positioned anywhere on film 3. In addition, film 3 may include any
number of shapes, buttons, membranes, etc., which may enable
convenient operation of the portable electronic device.
[0059] Referring to FIG. 1B, in some embodiments, film 3 may be
detachably or integrally coupled to a flat part of first frame 2
and/or second frame 4 through an attaching mechanism, such as a
seal 8 shown in FIG. 1B. For example, seal 8 may be directly
disposed on the flat part of first frame 2, such as the top side of
first frame 2. Seal 8 may include a very high bond (VHB) material.
Seal 8 may also include any colloidal substances or materials, and
double-sided adhesives. Seal 8 may also be formed by coating any
colloidal substances onto the flat part of first frame 2 to provide
the adhesive effect. Moreover, seal 8 may include an adhesive
material that is waterproof up to, for example, one meter below the
water surface. In some embodiments, when adhesive materials are
used, film 3 may not be replaceable. That is, replacing film 3 may
cause damage to film 3 and render it non-useable. Thus, in these
embodiments, film 3 may be made of or combined with strength
enhancing, anti-scratch or anti-breaking material, so that damage
to film 3 can be reduced or eliminated. Film 3 may thus have a
longer life span. In some other embodiments, seal 8 may allow film
3 to be replaced if it is scratched or damaged. Film 3 in these
embodiments may have a shorter life span but may be relatively
inexpensive. In addition, seal 8 may also be configured to be
impact-absorbing so that it may prevent or reduce the likelihood of
damage caused by impact, impinge, shock, and/or drop that are
imposed at the second frame and/or film 3 of case structure
1000.
[0060] Referring to FIG. 1B, in some embodiments, second frame 4
may be hingedly, rotatably, movably, permanently, detachably,
latchably, adhesively, integrally, and/or snugly coupled to first
frame 2. In addition, second frame 4, and the intervening first
frame 2, may also be detachably coupled to bottom cover 1 through,
for example, a coupling structure. In some embodiments, to provide
or enhance the waterproof or water-resistant capability, second
frame 4 may further include a plurality of (such as two) engaging
portions 41 configured to secure second frame 4 to bottom cover 1
through a plurality of (such as two) coupling structures 15 of
bottom cover 1. For example, the plurality of engaging portions 41
may be holes or openings that have same or similar dimension as the
plurality of coupling structures 15, such as protrusions. The holes
and protrusions may enable second frame 4 to be snugly coupled to
bottom cover 1 and thereby form a secured coupling to prevent or
reduce the likelihood of undesirable separating of case structure
1000. Therefore, when case structure 1000 is secured, it may be
provided with additional waterproof and water-resistant capability.
One of ordinary skill in the art would appreciate that positions of
coupling structures 15 and engaging portions 41 shown in FIG. 1B
are for illustration purpose and are not limiting. For example,
coupling structures 15 and engaging portions 41 may be placed in
external edges of case structure 1000. Coupling structures 15 may
be attached to engaging portions 41 by any means, such as by one or
more latch that may be located at the external edges of bottom
cover 1.
[0061] Referring to FIG. 1B, in some embodiments, second frame 4
may further include a plurality of casing buttons, such as casing
buttons 42, 43, and 44. Casing buttons 42, 43, and 44 may be
depressible and may be configured to operate their respective
underlying functioning mechanisms, such as a push button, a key, a
switch, a sliding control, a knob, or any other control mechanism,
of the portable electronic device. As an example, the material of
casing button 42 may include soft plastic, such as polypropylene,
soft rubber, and/or any other materials having similar
characteristics.
[0062] Referring to FIG. 1B, in some embodiments, casing button 42
may include an axis 421. When case structure 1000 is closed or
assembled, for example, casing button 42 may be detachably,
movably, or permanently coupled to or disposed in an opening 27
through axis 421. Axis 421 may enable coupling of casing button 42
in a manner that may allow casing button 42 to switch, move, slide,
tilt, and/or perform other similar motions. As an example, axis 421
may include a rotational axis and may be housed, coupled, or
gripped in a concave portion, slot, groove, and/or other similar
structures (not shown) in second frame 4. In some embodiments, such
structure may enable casing button 42 to engage in a motion as
described above to, for example, turn on and off a functional
button of the enclosed portable electronic device. In some
embodiments, such structure may itself move, slide, tilt, and/or
perform other similar motions to, for example, turn on and off a
functional button of the enclosed portable electronic device.
[0063] Referring to FIG. 1B, in some embodiments, casing buttons 43
and 44 may be detachably, movably, and/or permanently coupled to or
placed in openings 28 and 29 of first frame 2, respectively. In
some embodiments, when case structure 1000 encloses a portable
electronic device, such as an Apple iPhone.RTM. 5 device, openings
27, 28, and 29 may correspond to the ring/mute switch button, the
volume button, and the power button of the portable electronic
device, respectively. Therefore, a user may operate the functional
buttons of the portable electronic device (not shown) by, for
example, pressing on casing buttons 42, 43, and 44 of case
structure 1000. One of ordinary skill in the art would appreciate
that case structure 1000 may also include any number of openings
and casing buttons corresponding to the underlying functioning
mechanisms. The openings may be located, disposed, placed, or
arranged at any part of case structure 100 as desired.
[0064] Referring to FIGS. 1B and 1E, second frame 4 may further
include a connector 45, such as a band, a string, a rope, or a
connector having similar characteristics. In some embodiments,
connector 45 may be flexible and configured to enable, for example,
bending and/or stretching. As shown in FIGS. 1B and 1E, connector
45 may include a plurality of (such as three) openings, holes, or
perforations (collectively as perforation 451) that are configured
to enable a flexible connection of a cap 9. For example,
perforations 451 of the connector 45 may enable cap 9 to be easily
plugged or inserted into opening 22. One of ordinary skill in the
art would appreciate that the number of perforations 451 is not
limited to three as shown in FIGS. 1B and 1E, and may be any number
that is desired. Moreover, connector 45 may also prevent or reduce
the likelihood of undesired separation of cap 9 from case structure
1000. As an example, connector 45 may be coupled to cap 9 in a
manner that may prevent cap 9 from being misplaced such that cap 9
can be easily located and plugged into opening 22 when desired.
Furthermore, one of ordinary skill in the art would appreciate that
cap 9 and connector 45 may be two separate elements or may be an
integral single piece.
[0065] Referring to FIG. 1E, cap 9 may include a first body 91 and
a second body 92. First body 91 may have a shape corresponding to
that of opening 22, such as an opening corresponding to an earphone
jack, and may thus snugly plug into opening 22 for water-sealing
opening 22 and provide additional waterproof and/or
water-resistance capability to case structure 1000. Second body 92
may include a hand-operable portion that is detachably and/or
rotatably coupled to connector 45 as shown in FIG. 1E. In some
embodiments, a user may attach cap 9 to opening 22 by, for example,
rotating the hand-operable portion of second body 92 so that cap 9
may be, for example, screwed into a threaded opening 22.
[0066] FIG. 1F illustrates a partial, exploded view showing case
structure 1000 of FIG. 1A. Referring to FIGS. 1B and 1F, FIG. 1F
shows a partial structure of bottom cover 1 and first frame 2. In
some embodiments, bottom cover 1 may further include a lens
protecting structure 16, which may include a base 160, a first
structural element 161, a second structural element 162, a first
lens 163, and a second lens 164. First structural element 161 may
be directly coupled to base 160. First lens 163 and second lens 164
may be disposed in the two holes or openings of the first
structural element 161. Moreover, second structural element 162 may
include a plurality of holes or openings for coupling, attaching,
or assembling with a corresponding plurality of multiple
microstructures of base 160. As an example, when the plurality of
multiple microstructures are snugly inserted or coupled into the
plurality of holes or openings, lens protecting structure 16 may be
closed.
[0067] Referring to FIG. 1F, in some embodiments, first lens 163
and second lens 164 of lens protecting structure 16 may correspond
to the camera lens and the flash lens of the portable electronic
device. Moreover, at least one of first lens 163 and second lens
164 may include double anti-reflective coating for providing a high
transparency feature, thereby enabling first lens 163 and second
lens 164 to be anti-reflective. Anti-reflective coating may enable,
for example, the portable electronic device to obtain improved
picturing effect and result. One of ordinary skill in the art would
appreciate that first lens 163 and second lens 164 may also have
any other coating desired, such as anti-glare and anti-scratch
coatings.
[0068] FIG. 2A illustrates an exploded view showing the bottom
cover of case structure 1000 of FIG. 1A, with the bottom cover of
case structure 1000 being capable of coupling to an exemplary cap
132. Referring to FIG. 2A, bottom cover 1 may include a mounting
structure 12 and cap 132 on the opposing side of housing 11.
Mounting structure 12 may enable a mounting or coupling of various
external objects to case structure 1000, as a user may desire or as
a circumstance may require. In some embodiments, cap 132 may be
detachably coupled to mounting structure 12. The structure of
mounting structure 12 will be explained as following, and details
of the mounting mechanism will be described later.
[0069] Referring to FIG. 2A, in some embodiments, mounting
structure 12 may have a circular-shaped structure with one or more
grooves, slots, hooks, protrusions, etc. As an example, mounting
structure 12 may include a plurality of (such as three as shown in
FIG. 2A) engaging elements 121, such as protrusions, edges, slots,
hooks, grooves, etc., that are configured to engage, couple, and/or
secure cap 132 to mounting structure 12. The plurality of engaging
elements 121 may be separated with, for example, at least one
space, slot, or gap. The space, slot, or gap between any two
adjacent engaging elements 121 may form a plurality (such as three
shown in FIG. 2A) of engaging slots 122. Engaging slots 122 between
adjacent engaging elements 121 may have any size that is desired,
and may or may not have the same size as one another.
Correspondingly, cap 132 may include a plurality of (such as three)
engaging elements 131. In some embodiments, the structure and/or
shape of second engaging element 131 may be substantially the same
or similar to that of engaging elements 121 and/or engaging slots
122. In some embodiments, the length of engaging elements 131 may
be substantially the same as or smaller than engaging slots
122.
[0070] Referring to FIG. 2A, in some embodiments, cap 132 may be
rotatably and detachably coupled to mounting structure 12 by
inserting cap 132 into mounting structure 12 and rotating it with
respect to mounting structure 12 of bottom cover 1. As an example,
cap 132 may be inserted into mounting structure 12 by aligning
engaging elements 131 with engaging slots 122. When cap 132 is
inserted into mounting structure 12, it may rotate a certain degree
clockwise or counterclockwise with respect to mounting structure
12. In some embodiments, the protrusions of engaging elements 121
may include an end portion that is configured to stop cap 132 from
rotating and therefore enabling cap 132 to be engaged, coupled, or
secured to mounting structure 12.
[0071] Referring to FIG. 2A, in some embodiments, when cap 132 is
coupled to mounting structure 12, engaging elements 131, as shown
in FIG. 2A, may operatively engage or couple to respective engaging
elements 121, thereby securing cap 132 to mounting structure 12.
When cap 132 is secured to mounting structure 12, it may also
provide protection of the enclosed portable electronic device from
being damaged by water, shock, dust, oil, mud, snow, vibration,
spill, drop, impact, heat, frost, acid, chemical, corrosion, rain,
sand, and/or other forms of intrusion. Moreover, in some
embodiments, at least one of cap 132 and mounting structure 12 may
also include water-sealing ring or other sealing mechanisms. One of
ordinary skill in the art would appreciate that the above-described
mounting structure and its elements (such as engaging elements 121
and 131) are for illustration purposes and should not be construed
to limit the scope of the mounting structure.
[0072] Referring to FIG. 2A, the protrusion of engaging elements
121 may also include a surface portion that may prevent or
substantially reduce the likelihood of undesirable disengaging or
detaching of cap 132 from mounting structure 12. As an example, the
surface portion of one or both engaging elements 121 and 131 may
include at least one of a pattern, a surface texture, an engraving,
a monogram, and an embossment, for providing additional grip, so
that cap 132 may not unexpectedly rotate with respect to mounting
structure 12 and separate from it.
[0073] FIG. 2B illustrates a perspective view showing case
structure 1000 of the FIG. 2B attached or coupled to an exemplary
mounting adaptor 502. FIG. 2C illustrates a perspective view of
case structure 1000 detached from mounting adaptor 502 of FIG. 2B.
Referring to the FIGS. 2B and 2C, in some embodiments, mounting
adaptor 502 may include an adaptive structure 504 and an engaging
body 506 corresponding to mounting structure 12. Adaptive structure
504 will be described below in connection with FIG. 2D. Engaging
body 506 may also include a plurality of engaging elements that are
substantially the same as or similar to engaging elements 131 of
cap 132 shown in FIG. 2A. Therefore, the mechanism of mounting or
coupling engaging body 506 to mounting structure 12 may be also
substantially the same or similar to that described corresponding
to FIG. 2A and thus will not be described here.
[0074] FIG. 2D illustrates a perspective view showing an exemplary
coupling of case structure 1000 of FIG. 2A to an exemplary object,
such as an external mounting object 700, through the mounting
adaptor 502. Referring to FIGS. 2B, 2C, and 2D, in some
embodiments, adaptive structure 504 of mounting adaptor 502 may be
configured to enable freedom of movement of mounting adaptor 502
with respect to external mounting object 700. For example, adaptive
structure 504 may be of a ball-shape, so that it may be snugly fit
into external mounting object 700 and enable adaptive structure 504
to be adaptively, hingedly, rotatably, movably, permanently,
detachably, latchably, and/or snugly coupled to external mounting
object 700.
[0075] Referring to FIG. 2D, in some embodiments, external mounting
object 700 may include a housing space 704 and a mounting body 702.
Housing space 704 may include a notch-structure corresponding to
adaptive structure 504. As shown in FIG. 2D, in some embodiments,
adaptive structure 504 enables mounting adaptor 502 to be coupled
to both case structure 1000 and external mounting object 700. As an
example, case structure 1000 may be coupled or attached to mounting
adaptor 502 through mounting structure 12, and mounting adaptor 502
may be movably or rotatably coupled to external mounting object 700
through adaptive structure 504. In addition, external mounting
object 700 may further attach to a surface or another object (not
shown) through a mounting body 702. As an example, mounting body
702 may include a suction disc with suction capability, thereby
enabling coupling of mounting body 702 (together with mounting
adaptor 502 and case structure 1000) to, for example, a table, a
glass surface of a car, or any other surface. The object to which
mounting body 702 couples or attaches may or may not be a flat
surface. One of ordinary skill in the art would appreciate that the
attaching of mounting body 702 to an object can include any
mechanism desired and is not limited to that shown in FIG. 2D. In
some embodiments, when case structure 1000 is coupled to an object
(not shown) through mounting adaptor 502 and external mounting
object 700, a user may be enabled to operate the enclosed portable
electronic device without having to hold the device. In addition,
one or both external mounting object 700 and mounting adaptor 502
may also provide cushioning or vibration reduction, thereby
preventing or reducing the likelihood of damage via vibration,
shaking, etc., of the portable electronic devices and/or case
structure 1000.
[0076] Referring to FIG. 2D, in some embodiments, an upper portion
of mounting adaptor 502 (not including adaptive structure 504) may
itself be adaptively, hingedly, rotatably, movably, permanently,
detachably, latchably, and/or snugly adapted or coupled to adaptive
structure 504, thereby adding another degree of freedom. For
example, the upper portion of mounting adaptor 502 may be coupled
to adaptive structure 504 in such a manner that it can move a
substantial degree with respect to adaptive structure 504,
therefore enabling tilting and/or rotating of case structure 1000
with respect to adaptive structure 504.
[0077] Referring to FIG. 2D, in some embodiments, adaptive
structure 504 of mounting adaptor 502 may be detachably or
removably secured to external mounting object 700. As a result, a
user may conveniently detach or separate case structure 1000 and/or
mounting adaptor 502 from an external object without having to
remove external mounting object 700 from the external object to
which it is attached. In other words, the detachability or
removability of mounting adaptor 502 from external mounting object
700 enables easy mounting, detaching, and carrying of case
structure 1000 and the enclosed portable electronic device.
Furthermore, in some embodiments, because a user may easily detach
or separate mounting adaptor 502 from external mounting object 700
and does not need to carry external mounting object 700, the
material and design of external mounting object 700 may be enhanced
and/or strengthened. For example, external mounting object 700 may
be strengthened by using heavier and/or robust materials or by
designing with additional features. The weight of external mounting
object 700 therefore may be of a less concern because a user may
not need to carry it.
[0078] One of ordinary skill in the art would appreciate that the
mounting structure is not limited to those shown in FIGS. 2C and
2D, and may include any desired structure. For example, a mounting
structure may enable the mounting of a detachable handle, instead
of mounting adaptor 502, to case structure 1000. In some exemplary
embodiments, the mounting structure may include a hand-operable
screw, instead of engaging elements 121 and 131 shown in FIG. 2A.
For example, bottom cover 1 may include a mounting point, and by
fastening a hand-operateable screw using a screw cap, a mounting
body of a detachable handle may be attached to bottom cover 1
through the mounting point. The attachment may enable manipulation
of case structure 1000 through the detachable handle. The mounting
point of bottom cover 1, for example, may be a screw hole having a
thread that is compatible with a standard camera tripod having a
connection including, for example, 1/4-20 UNC threads. Thus, a
tripod or any other handling or supporting structures that have a
tripod-compatible screw may be connected or coupled to case
structure 1000.
[0079] In some embodiments, the mounting of a detachable handle may
use a magnetic mounting mechanism. For example, bottom cover 1 may
include at least one of a permanent magnet and a ferromagnetic
material. The magnets may be composed of NdFeB, NIB, or Neo. An
external mounting object may also include magnets or otherwise be
configured to have magnetic properties so it can be magnetically
coupled to bottom cover 1 in a substantially secure manner, in
order to prevent unintended detachment by gravity, by vibration, or
by the force of a user's operation of the portable electronic
device enclosed in case structure 1000. The strength of the
magnetic field of bottom cover 1 or the external mounting object,
however, may be controlled so that it does not affect or
substantially affect the operation of the portable electronic
device. In addition, magnetic shielding materials may be included
in bottom cover 1 to prevent the magnetic field from interfering
with the electronic device. For example, a layer of sheet metal,
metal screen, or metal foam may be included in bottom cover 1. A
layer of metallic ink or similar material may also be coated inside
bottom cover 1 to provide the shielding. Further, one of ordinary
skill in the art would appreciate that a mounting adaptor, a
detachable handle, or an external mounting object may be mounted to
case structure 1000 by any type of mounting mechanism that is
desired.
[0080] FIG. 3A illustrates a perspective view of an exemplary case
structure 2000. FIG. 3B illustrates an exploded view of case
structure 2000 of FIG. 3A. Referring to FIGS. 3A and 3B, case
structure 2000 is provided for housing or enclosing a portable
electronic device (not shown), such as an Apple iPad.RTM. or
iPad.RTM. mini device, and is configured to prevent or reduce the
likelihood of shock/drop/impact-, water-, dust-, and/or
chemical-damage of the portable electronic device. Case structure
2000 may be substantially waterproof, such as waterproof in
compliance with class IP68 according to the U.S. National
Electrical Manufacturers Association rating. The types of portable
electronic devices that are capable of being enclosed in case
structure 2000 may include, but are not limited to, a cell phone, a
smart phone, an MP3 player, a portable computer, and a tablet PC, a
personal digital assistant, and/or other similar portable
electronic devices.
[0081] Referring to FIGS. 3A and 3B, according to some embodiments,
case structure 2000 may include bottom cover 1, film 3, first frame
2, and second frame 4. In some embodiments, bottom cover 1 may
include a first bottom cover 1a and a second bottom cover 1b.
Second frame 4 may be detachably coupled to or integrated with
first frame 2 so as to form a single piece. And second bottom cover
1b may be detachably coupled to or integrated with first bottom
cover 1a. Film 3 may be coupled to one or both first bottom cover
1a and first frame 2, and be placed between the two. In some
embodiments, first bottom cover 1a may be detachably coupled to or
integrated with first frame 2. The dimensions and aspect ratios of
second bottom cover 1b, first frame 2, and second frame 4 may be
substantially the same. The dimensions of first bottom cover 1a may
be substantially or slightly smaller than those of second bottom
cover 1b, first frame 2, and second frame 4, so that it may be
coupled to or accommodated by second bottom cover 1b, bottom cover
1, and second frame 4. Referring to FIG. 3A, case structure 2000 is
illustrated in an assembled condition, and thus, some elements of
case structure 2000 may not be marked or labeled in FIG. 3A.
[0082] The materials of case structure 2000 may include, for
example, polypropylene (PP), polycarbonate (PC), or thermoplastic
polyurethane (TPU), or any other material having similar
characteristics. As an example, in some embodiments, the material
of first bottom cover 1a may include PC; the material of second
bottom cover 1b may include TPU; the material of first frame 2 may
include PC; and the material of second frame 4 may include TPU. In
addition, second bottom cover 1b can be manufactured by a
double-injection manufacturing process. One of ordinary skill in
the art would appreciate that the material of each element of the
case structure 2000 may not be limited to those described above and
may include any other material desired. For example, the material
of some elements of case structure 2000 may include metal, alloy,
stainless steels, nylons, hard plastics, iron, aluminum, lead,
and/or other materials having similar characteristics.
[0083] FIG. 3C illustrates a partial, cross-sectional view of case
structure 2000 of FIG. 3A. FIG. 3D illustrates a partial, enlarged
cross-sectional view of case structure 2000 of FIG. 3A. Referring
to FIGS. 3B, 3C, and 3D, first bottom cover 1a may include housing
11. In some embodiments, housing 11 may include a flat structure,
such as a flat bed, for accommodating or housing a portable
electronic device, such as an Apple.RTM. iPad mini device. The
dimensions of housing 11 may correspond to the structure and/or
dimensions of the portable electronic device housed therein, and
may not be limited to those shown in FIGS. 3B-3D. In some
embodiments, first bottom cover 1a may include groove 14
surrounding at least a portion of the periphery of housing 11.
Groove 14 may be formed by, for example, water barrier 13 and the
internal peripheral portion of first bottom cover 1a. In some
embodiments, first frame 2 may have a convex portion 20
corresponding to groove 14. When case structure 2000 is closed,
convex portion 20 of first frame 2 may be partially or entirely
inserted or disposed in groove 14. One of ordinary skill in the art
would appreciate that groove 14 may be included in other places. As
an example, in some embodiments, groove 14 may be included in first
frame 2 or second frame 4. Correspondingly, in these embodiments,
convex portion 20 may be included in the opposing frame or cover,
such as first bottom cover 1a.
[0084] Referring to FIGS. 3C and 3D, in some embodiments, groove 14
may include first coupling portion 141 on the side that is further
away from housing 11. For example, first coupling portion 141 may
be included in the peripheral of first bottom cover 1a. Groove 14
may also include a plurality of second coupling portions 142 on the
side that is close to or near housing 11. For example, second
coupling portions 142 may be included in water barrier 13. In some
embodiments, second coupling portions 142 may be separately or
discontinuously disposed between groove 14 and accommodating or
housing 11, such as disposed in water barrier 13.
[0085] Referring to FIGS. 3C and 3D, in some embodiments, convex
portion 20 of first frame 2 may include at least one first coupling
element 201 and a plurality of second coupling elements 202,
corresponding to first coupling portion 141 and second coupling
portions 142, respectively. In some embodiments, when case
structure 2000 is closed, and therefore convex portion 20 is in
contact with or inserted into groove 14, first coupling element 201
and second coupling elements 202 may be hingedly, rotatably,
movably, permanently, detachably, latchably, and/or snugly coupled
or engaged with first coupling portion 141 and second coupling
portions 142, respectively. First coupling element 201, second
coupling elements 202, first coupling portion 141, and second
coupling portions 142, may thus form of a water-sealing or
water-resistant structure configured to provide water-resistant or
waterproof capability to case structure 2000. As an example, first
coupling portion 141 and first coupling element 201 may each
include a protrusion that may be engaged with each other to form a
tight coupling. As another example, second coupling elements 202
may include a plurality of separated protrusions so that they may
be engaged with a corresponding plurality of second coupling
portions 142, such as a plurality of slots or small openings.
Moreover, in some embodiments, the protrusions of second coupling
elements 202 may be semi-circle shaped structures, so that a user
may be provided with a smoother and more convenient experience for
attaching and/or detaching of case structure 2000. One of ordinary
skill in the art would appreciate that for forming a water-sealing
or water-resistant structure, some but not all first coupling
element 201, second coupling elements 202, first coupling portion
141, and second coupling portions 142 may be needed.
[0086] Referring to FIGS. 3C and 3D, water barrier 13 may further
include a plurality of protrusions 162 configured to enhance the
strength of water barrier 13. As an example, FIGS. 3C and 3D
illustrate that the plurality of protrusion 162 may include one or
more curved fins configured to provide additional support and
structural strength to water barrier 13, so that likelihood of
breaking, distorting, fracturing, chipping, bending, and/or other
similar damage may be prevented or reduced.
[0087] Referring to FIGS. 3B-3D, case structure 2000 may include a
seal strip 5 configured to provide additional water-sealing or
water-resistance capability of the water-sealing or water-resistant
structure that includes groove 14 and convex portion 20.
Additionally, seal strip 5 and the water-sealing structure, which
may include first coupling element 201, second coupling elements
202, first coupling portion 141, and second coupling portions 142,
may also provide protection of the enclosed portable electronic
device from being damaged by water, shock, dust, oil, mud, snow,
vibration, spill, drop, impact, heat, frost, acid, chemical,
corrosion, rain, sand, and/or other forms of intrusion. In some
embodiments, seal strip 5 may be disposed within groove 14 and in
contact with convex portion 20 when case structure 2000 is closed.
In addition, seal strip 5 may also provide buffering or cushioning
so that it reduces or prevents the likelihood of damage at the
coupling area of first bottom cover 1a and/or first frame 2. In
some embodiments, the material of the seal strip 5 may include
silicone, rubber, thermoforming plastics, polyvinylchoride
materials, polycarbonate, polyethylene terephthalate (PET), poly
methyl methacrylate acrylic (PMMA), adhesive tape, and/or any
material having similar characteristics. Seal strip 5 may be
formed, for example, by a molding processing.
[0088] FIG. 3E illustrates a partial, exploded view of case
structure 2000 of FIG. 3A. Referring to FIGS. 3B and 3E, in some
embodiments, first bottom cover 1a may include a plurality of, such
as two, recess portions 74. Correspondingly, a bottom side 21 of
first frame 2 may include a plurality of, such as two, openings
22a. Openings 22a may be located, for example, corresponding to the
positions of the speaker and the microphone of the portable
electronic device, and may also be referred to as audio holes.
Therefore, when the portable electronic device is accommodated,
housed, or enclosed in case structure 2000, recess portions 74 may
align with the corresponding openings 22a, and thus enable a user
to operate the speaker and the microphone functions without the
need to remove the portable electronic device from case structure
2000. Furthermore, openings 22a, or the audio holes, may also
include a waterproof or water-resistant, but sound transmissive
film (not shown), so that the impact of sound transmitting quality
through the openings 22a may be reduced while the portable
electronic device may still be protected from water damage.
[0089] Referring to FIG. 3E, in some embodiments, first bottom
cover 1a may further include openings 22 and 23. Opening 22 and
opening 23 may be placed, for example, corresponding to the
positions of an earphone jack and a charging and communication
connector of the portable electronic device, respectively.
Therefore, when the portable electronic device is accommodated,
housed, or enclosed in case structure 2000, opening 22 and opening
23 may enable a user to operate the earphone function and charging
and communication functions of the portable electronic device
without the need to remove the portable electronic device from case
structure 2000.
[0090] Referring to FIGS. 3B and 3E, second bottom cover 1b may be
configured to cover first bottom cover 1a. For example, second
bottom cover 1b and first bottom cover 1a may be coupled to or
assembled snugly or tightly through coupling structures, such as
one or more microstructures. In some embodiments, first bottom
cover 1a may include a plurality of, such as three, securing
portions 101 placed, for example, at the corners of first bottom
cover 1a. Securing portions 101 may be placed corresponding to a
plurality of, such as three, openings 56 of second bottom cover 1b.
Referring to FIG. 3E, in some embodiments, first bottom cover 1a
and second bottom cover 1b may be hingedly, rotatably, movably,
permanently, detachably, latchably, screwingly, and/or snugly
coupled or attached to each other by, for example, coupling
securing mechanisms 72 to securing portions 101 through openings
56. As an example, securing portions 101 may include threaded screw
holes corresponding to threaded securing mechanisms 72, such as
screws. Thus, securing mechanisms 72 may be coupled to or attached
to securing portions 101 by the screw threads. One of ordinary
skill in the art would appreciate that positions of securing
mechanisms 72, openings 56, or securing portions 101 shown in FIGS.
3B and 3E are for illustration purpose and are not limiting.
Furthermore, securing mechanism 72 may be attached to securing
portions 101 by any means, such as by one or more latch that may be
located at the external edges of first or second bottom covers 1a
or 1b.
[0091] Referring to FIGS. 3B and 3E, in some embodiments, second
bottom cover 1b may further include a cap 51 corresponding to
opening 23. Cap 51 may be configured to be resealable to prevent or
reduce the likelihood of water damage. For example, cap 51 may
include a resealable cover and/or a seal strip. When the charging
or communication function of the portable electronic device is not
used, the resealable cover and/or the seal strip of cap 51 may at
least be partially plugged or inserted into opening 23 so that it
enhances or improves the waterproof, water-resistant and/or the
dust-resistant capability of case structure 2000. In some
embodiments, cap 51 may be integrated with second bottom cover 1b
and thus form a single piece.
[0092] Referring to FIGS. 3B and 3E, in some embodiments, cap 51
and opening 23 may be configured to correspond in dimension and/or
shape with respect to each other so that the two may be secured
snugly or tightly. In some embodiments, cap 51 may be configured
with a different dimension and/or shape so that it may include, for
example, a screw thread that enables a screwing mechanism (not
shown) configured to secure cap 51 with opening 23.
[0093] Referring to FIGS. 3B and 3E, in some embodiments, second
bottom cover 1b may include a plurality of casing buttons, such as
casing buttons 42, 52, and 53. Casing buttons 42, 52, and 53 may be
depressible for operating the underlying functioning mechanisms,
such as push buttons, keys, switches, sliding controls, knobs, or
other control mechanisms, of the portable electronic device. As a
non-limiting example, the material of casing button 52 include soft
plastic, such as polypropylene, soft rubber, and/or any other
materials having similar characteristics.
[0094] Referring to FIGS. 3B and 3E, in some embodiments, when case
structure 2000 is closed or assembled, for example, casing buttons
52 and 53 may be detachably, movably, or permanently coupled to or
disposed in openings 17 and 18 of first bottom cover 1a,
respectively. In some embodiments, when case structure 2000
encloses a portable electronic device, openings 17 and 18, and
respective casing buttons 52 and 53, may correspond to, for
example, the power button and the volume up/down button of the
portable electronic device, respectively. Casing button 42 may
correspond to, for example, the ring/mute button of the portable
electronic device. One of ordinary skill in the art would
appreciate that case structure 2000 may also include any number of
openings corresponding to the underlying functioning mechanisms.
The openings may be placed, disposed, or arranged at any locations
desired. Referring to FIGS. 3B and 3E, in some embodiments, a user
may operate the buttons of the portable electronic device (not
shown) by, for example, pressing on casing buttons 42, 52, and 53
of case structure 2000, without having to remove the portable
electronic device from case structure 2000.
[0095] Referring to FIG. 3B, in some embodiments, at least a
portion of film 3 may be coupled to first frame 2 and may be
configured to enable a user to view and operate an enclosed
portable electronic device. In some exemplary embodiments, film 3
may include materials such as thermoforming plastics,
polyvinylchoride materials, polycarbonate, polyethylene
terephthalate (PET), poly methyl methacrylate acrylic (PMMA),
adhesive tape, and/or any other materials having similar
characteristics. Film 3 may be flexible but also may have an
enhanced strength so that it may withstand a water pressure under a
higher water resistance standard. As an example, film 3 may be
capable of withstanding a condition that is specified in the IPX7
standard, i.e., a water immersion for at least 30 minutes at a
depth of at least one meter. Film 3 may also be capable of
withstanding a condition of a higher IPX8 standard, i.e., a
continual submersion in water under conditions which are identified
by the manufacturer. As another example, film 3 may also be capable
of withstanding the IP65 standard.
[0096] Film 3 may also be a clear/transparent or substantially
clear/transparent water-resistant film so that a user can view the
screen or a substantial portion of the screen of the portable
electronic device. In addition, film 3 may also enable a user's
operation of the portable electronic device when it is enclosed in
case structure 2000. For example, some portable electronic devices
may have capacitive-type touch sensors that are incorporated in the
touch-point screens. A user may operate these portable electronic
devices by touching and/or moving a fingertip on the surface of the
touch-point screen. Film 3 may thus be a touch-sensitive or
transmissive film that enables the user to operate a touch-point
screen of the portable electronic device through film 3. As a
result, operations may be carried out without opening case
structure 2000. In other words, film 3 may enable the portable
electronic device to be operated when it is immersed under water or
under other conditions that require the portable electronic device
to be enclosed in case structure 2000. One of ordinary skill in the
art would appreciate that film 3 may also be other types of films
that can enable operation of the portable electronic device, such
as resistance-sensitive films.
[0097] In some embodiments, film 3 may also be an anti-reflection
film, an anti-glare film, an anti-fingerprint film, a monitor
filtering film, and/or other similar films. For example, film 3 may
filter out the light reflected from the smooth glass surface of the
touchscreen device as well as the radiation emitted from the
portable electronic device. This may be used to protect the user's
privacy by decreasing the viewing angle of the touchscreen of the
portable electronic device. In addition, film 3 may also be able to
dissipate static electrical charge buildup. Film 3 may also be
polarized, colorized, or tinted, depending on the application.
[0098] A portable electronic device may have buttons or switches,
such as the "home" button on an Apple iPad.RTM. mini device.
Therefore, in some exemplary embodiments, film 3 may include a
corresponding convex or concave shape to enable convenient
operation of the portable electronic device. As an example, for an
Apple iPad.RTM. mini device, film 3 may include a concave circle
near the bottom edge (not shown) for operating of the "home"
button. One of ordinary skill in the art would appreciate that the
concave circle may be positioned anywhere on film 3. In addition,
film 3 may include any number of shapes, buttons, membranes, etc.,
which may enable ease of operation of the portable electronic
device.
[0099] Referring to FIGS. 3B-3D, in some embodiments, film 3 may be
detachably or integrally coupled to a flat part of first frame 2
and/or second frame 4 through an attaching mechanism, such as an
seal 8 shown in FIG. 3B. For example, seal 8 may be directly
disposed on the flat part, such as a lower surface, of first frame
2. Seal 8 may include a VHB material. Seal 8 may also include any
colloidal substances or materials, and double-sided adhesives. Seal
8 may also be formed by coating any colloidal substances on the
flat part of first frame 2 to provide the adhesion effect.
Moreover, seal 8 may include an adhesive material that is
waterproof up to, for example, one meter below the water surface.
In some embodiments, when the adhesive materials are used, film 3
may not be replaceable. That is, replacing film 3 may cause damage
to film 3 and render it non-useable. Thus, in these embodiments,
film 3 may be made of or combined with strength enhancing,
anti-scratch or anti-breaking material, so that damage to film 3
can be reduced or eliminated. Film 3 may thus have a longer life
span. In some other embodiments, seal 8 may allow film 3 to be
replaced if it is scratched or damaged. Film 3 in these embodiments
may have a shorter life span but may be relatively inexpensive. In
addition, seal 8 may also be configured to be impact-absorbing so
that it may prevent or reduce the likelihood of damage caused by
impact, impinge, shock, and/or drop that are imposed at the second
frame and/or film 3 of case structure 2000.
[0100] Referring to FIG. 3B, in some embodiments, case structure
2000 may include second frame 4, which may be hingedly, rotatably,
movably, permanently, detachably, latchably, adhesively, and/or
snugly coupled to first frame 2. In addition, second frame 4, and
the intervening first frame 2, may also be detachably coupled to
first bottom cover 1a and/or second bottom cover 1b through, for
example, a coupling structure. In some embodiments, to provide or
enhance the waterproof or water-resistant capability, second frame
4 may further include one or more engaging portions 41 configured
to secure second frame 4 to first frame 2. For example, when a user
press on an engaging portion 41, second frame 4 may be snugly or
tightly coupled to first frame 2, thereby forming a secured
coupling to prevent or reduce the likelihood of undesired
separation of case structure 2000. In some embodiments, engaging
portion 41 may also enable a user to separate or dissemble case
structure 2000 when desired. For example, when a user pulls
engaging portion 41 (and together the second frame 4) away from
first frame 2, second frame 4 may be conveniently separated or
released from first frame 2 and/or first bottom cover 1a.
[0101] Referring to FIGS. 3B and 3E, case structure 2000 may
further include cap 9. Cap 9 may include a first body 91 and a
second body 92. First body 91 may have a shape corresponding to
that of opening 22, such as an opening corresponding to an earphone
jack, and may thus snugly plug into opening 22 to provide
additional waterproof and/or water-resistance capability to case
structure 2000. Second body 92 may include a hand-operable portion
that is coupled to first body 91. In some embodiments, a user may
attach cap 9 to opening 22 by, for example, rotating the
hand-operable portion of second body 92 so that cap 9 may be, for
example, screwed into a threaded opening 22.
[0102] Referring to FIGS. 3B and 3E, second bottom cover 1b may
further include a lens protecting structure 54, which may include a
base 540 and a lens 541. Lens 541 may be coupled to or placed in
base 540. Additionally, first bottom cover 1a may include an
opening 19 corresponding to lens protecting structure 54. Opening
19 may be configured to encompass the whole area of lens protecting
structure 54, thereby enabling, for example, a camera function of
the portable electronic device to be operated without the need to
remove the portable electronic device from case structure 2000.
[0103] Referring to FIGS. 3B and 3E, lens 541 of lens protecting
structure 54 may correspond to the camera lens of the portable
electronic device. Moreover, lens 541 may include a double
anti-reflective coating to obtain the high-transparency feature,
and thereby enabling lens 541 to be anti-reflective.
Anti-reflective coating may enable, for example, the portable
electronic device to obtain improved picturing effect and result.
One of ordinary skill in the art would appreciate that lens 541 may
also have any other coating desired, such as anti-glare and
anti-scratch coatings
[0104] FIG. 4A illustrates an exploded view showing first bottom
cover 1a of case structure 2000 of FIG. 3A, with first bottom cover
1a of the case structure being capable of coupling to cap 132. For
example, first bottom cover 1a may include mounting structure 12
configured to couple to cap 132, mounting adaptor 502, or any other
objects. FIG. 4B illustrates a perspective view showing case
structure 2000 of FIG. 3A attached or coupled to mounting adaptor
502. FIG. 4C illustrates a perspective view of case structure 2000
detached from mounting adaptor 502 of FIG. 3A. FIG. 4D illustrates
a perspective view showing an exemplary coupling of case structure
2000 of FIG. 4A to external mounting object 700. Mounting structure
12, cap 132, mounting adaptor 502, and other mounting elements of
case structure 2000 shown in FIGS. 4A-4D may be the same as or
substantially similar to those described in connection with FIGS.
2A-2D, and thus will not be described here.
[0105] One of ordinary skill in the art would appreciate that the
mounting structure is not limited to those shown in FIGS. 4C and
4D, and may include any other similar structures that are desired.
For example, a mounting structure may enable the mounting of a
detachable handle, instead of mounting adaptor 502, to case
structure 2000. In some exemplary embodiments, the mounting
structure may include a hand-operable screw, instead of engaging
elements 121 and 131 shown in FIG. 4A. For example, first bottom
cover 1a may include a mounting point, and by fastening a
hand-operable screw using a screw cap, a mounting body of a
detachable handle may be attached to first bottom cover 1a through
the mounting point. The attachment may enable manipulation of case
structure 2000 through the detachable handle. The mounting point of
first bottom cover 1a, for example, may be a screw hole having a
thread that is compatible with a standard camera tripod having a
connection including, for example, 1/4-20 UNC threads. Thus, a
tripod or any other handling or supporting structures that have a
tripod-compatible screw may be connected or coupled to case
structure 2000.
[0106] In some exemplary embodiments, the mounting of a detachable
handle may use a magnetic mounting mechanism. For example, first
bottom cover 1a may include at least one of a permanent magnet and
a ferromagnetic material. The magnets may be composed of NdFeB,
NIB, or Neo. An external mounting body may also include magnets or
otherwise be configured to have magnetic properties so it can be
magnetically coupled to first bottom cover 1a in a substantially
secure manner, such as without detachment by gravity, by vibration,
or by the force of a user's operation of the portable electronic
device enclosed in case structure 2000. The strength of the
magnetic field of first bottom cover 1a or the external mounting
body, however, may be controlled so that it does not affect or
substantially affect the operation of the portable electronic
device. In addition, magnetic shielding materials may be included
in first bottom cover 1a to prevent the magnetic field from
interfering with the electronic device. For example, a layer of
sheet metal, metal screen, or metal foam may be included in first
bottom cover 1a. A layer of metallic ink or similar material may
also be coated inside first bottom cover 1a to provide the
shielding. Further, one of ordinary skill in the art would
appreciate that a mounting element, a detachable handle, or an
external mounting body may be mounted to case structure 2000 by any
type of mounting mechanism that is desired.
[0107] Referring to FIGS. 4B and 4C, in some embodiments, case
structure 2000 may further include a carrying mechanism, such as an
opening 55 at bottom side 50 of second bottom cover 1b. Opening 55
may be configured to enable case structure 2000 to be attached to
other objects or a carrying person via a hanging or carrying
mechanism, such as a lanyard, rope, a band, a belt, a string, a
hook, and/or any other similar carrying mechanisms. One of ordinary
skill in the art would appreciate that case structure 2000 may
include any number of openings located anywhere on case structure
2000.
[0108] FIG. 5A illustrates a perspective view of an exemplary case
structure 3000. FIG. 5B illustrates an exploded view of case
structure 3000 of FIG. 5A. Referring to FIGS. 5A and 5B, case
structure 3000 is provided for housing or enclosing a portable
electronic device (not shown), such as an Apple iPhone 5.RTM.
device, and therefore enables preventing or reducing the likelihood
of shock/drop/impact-, water-, dust-, and/or chemical-damage of the
portable electronic device. Case structure 3000 may be
substantially waterproof or water-resistant, such as substantially
waterproof in compliance with class IP65 according to the U.S.
National Electrical Manufacturers Association rating. The types of
portable electronic devices that are capable of being enclosed in
case structure 3000 may include, but are not limited to, a cell
phone, a smart phone, an MP3 player, a portable computer, a tablet
PC, a personal digital assistant, or any other similar devices.
[0109] Referring to FIGS. 5A and 5B, according to some embodiments,
case structure 3000 may include bottom cover 1, first frame 2, film
3, second frame 4, and a layer 10. In some embodiments, first frame
2 may be detachably coupled to bottom cover 1. Layer 10 may be
placed between bottom cover 1 and first frame 2. Layer 10 may also
form an integral piece with bottom cover 1. Second frame 4 may be
detachably coupled to or integrated with first frame 2 so as to
form a single piece. Film 3 may be placed between second frame 4
and first frame 2. In some embodiments, the dimensions of bottom
cover 1 and second frame 4 may be substantially the same or
similar. In some embodiments, the dimensions of first frame 2 may
be substantially similar or slightly smaller than bottom cover 1
and/or second frame 4 so that it may be coupled to or accommodated
by bottom cover 1 and second frame 4. Referring to FIG. 5A, case
structure 3000 is illustrated in an assembled condition, and thus,
some elements of case structure 3000 may not be marked or labeled
in FIG. 5A.
[0110] The material of the case structure 3000 may include
polypropylene (PP), polycarbonate (PC), thermoplastic polyurethane
(TPU), and/or any other material having similar characteristics. As
an example, in some embodiments, the material of second frame 4 may
include polycarbonate. And bottom cover 1 and first frame 2 may be
formed by a double-injection molding process using thermoplastic
polyurethane and polycarbonate. One of ordinary skill in the art
would appreciate that the material of each element of the case
structure 3000 may not be limited to those described above and may
include any other material desired. For example, the material of
some elements of case structure 3000 may include metal, alloy,
stainless steels, nylons, hard plastics, iron, aluminum, lead,
and/or other materials having similar characteristics.
[0111] FIG. 5C illustrates another exploded view of case structure
3000 of FIG. 5A. Referring to FIG. 5C, in some embodiments, first
frame 2 may be formed or integrated with bottom cover 1 and
therefore formed as an integral single piece (together shown as
bottom cover 1 in FIG. 5C). As shown in FIG. 5C, second frame 4 may
be detachably coupled to or assembled with bottom cover 1 (and the
integrated first frame 2).
[0112] Referring to FIGS. 5B and 5C, in some embodiments, bottom
cover 1 may include a plurality of, such as two, coupling
structures 32, and second frame 4 may include a plurality of, such
as two, corresponding engaging portions 34. Coupling structures 32
and engaging portions 34 may be configured to enable bottom cover 1
and second frame 4 to be hingedly, rotatably, movably, permanently,
detachably, latchably, and/or snugly coupled or engaged to prevent
or reduce the likelihood of undesirable separating of case
structure 3000. For example, coupling structures 32, such as
latches and engaging portions 34, such as corresponding latching
slots, as shown in FIG. 5B (and any intervening structures or
layers including first frame 2 and layer 10) may enable the user to
close or assemble case structure 3000 and therefore enclose a
portable electronic device. One of ordinary skill in the art would
appreciate that positions of coupling structures 32 and engaging
portions 34 shown in FIG. 5B are only exemplary and are not
limiting. For example, coupling structures 32 and engaging portions
34 may be placed in other external edges of case structure 3000.
One of ordinary skill in the art would appreciate that coupling
structures 32 may also be attached to engaging portions 34 by any
means.
[0113] Referring to FIGS. 5B and 5C, in some embodiments, coupling
structures 32 may include an axis 321. When case structure 3000 is
closed or assembled, for example, coupling structures 32 may, for
example, pivotally rotate surrounding axis 321 and therefore couple
to engaging portion 34. Axis 321 may enable coupling of coupling
structures 32 in a manner that may allow coupling structures 32 to
rotate, switch, move, slide, tilt, and/or perform other similar
motions so as to engage with or couple to engaging portion 34. As
an example, axis 321 may include a rotational axis and may be
housed, coupled, or gripped in a concave portion, slot, groove,
and/or other similar structures (not shown) in bottom cover 1.
[0114] Referring to FIGS. 5B and 5C, in some embodiments, second
frame 4 may include groove 14 surrounding at least a portion of the
periphery of second frame 4. Correspondingly, first frame 2 shown
in FIG. 5B, or the integrated bottom cover 1 shown in FIG. 5C, may
include convex portion 20. In some embodiments, groove 14 may be
included in bottom cover 1 or first frame 2, and convex portion 20
may be included in second frame 4. In other words, groove 14 and
convex portion 20 may be included in any of the second frame 4 and
bottom cover1/first frame 2, as long as they are opposing each
other.
[0115] Referring to FIGS. 5B and 5C, groove 14 may include a
plurality of coupling portions 431, such as latches, hooks,
protrusions, bars, and/or similar engaging or coupling portions.
For example, as shown in FIG. 5C, the inner sidewall of groove 14
may include two or more coupling portions 431, such as engaging
slots. Correspondingly, convex portion 20 may include a plurality
of coupling elements 432, such as latches, hooks, protrusions,
and/or similar engaging or coupling elements. In some embodiments,
when case structure 3000 is closed, convex portion 20 may at least
partially couple to or engage with groove 14. When convex portion
20 is at least partially and directly engaged with or coupled to
groove 14, coupling elements 432 may hingedly, rotatably, movably,
permanently, detachably, latchably, and/or snugly couple to or
engage with the corresponding plurality of coupling portions 431,
thereby forming a water-sealing or water-resistant structure for
providing water-resistant or waterproof capability to case
structure 3000. For example, as shown in FIGS. 5B and 5C, when case
structure 2000 is closed, coupling elements 432, such as
protrusions, may tightly engage with or snap into coupling portions
431, such as engaging slots. The coupling mechanisms, such as those
described above, which include coupling elements 432 and coupling
portions 431, may further provide or enhance the capability of case
structure 3000 to enclose and protect the portable electronic
device disposed therein, and thus prevent the undesired separation
of case structure 3000.
[0116] In some embodiments, groove 14 may further include a seal
strip (not shown) configured to provide additional or enhanced
water-sealing or water-resistance capability of the water-sealing
or water-resistant structure as discussed above. Additionally, the
seal strip and the water-sealing structure, which may include
groove 14, coupling portions 431, convex portion 20, and coupling
elements 432, may also provide protection of the enclosed portable
electronic device from being damaged by water, shock, dust, oil,
mud, snow, vibration, spill, drop, impact, heat, frost, acid,
chemical, corrosion, rain, sand, and/or other forms of intrusion.
In some embodiments, when case structure 3000 is closed, the seal
strip may be disposed within groove 14 and in contact with convex
portion 20. The seal strip may also provide buffering or cushioning
so that it reduces or prevents, for example, the likelihood of
damage at the coupling area between bottom cover 1 and second frame
4. In some embodiments, the material of the seal strip may include
silicone, rubber, thermoforming plastics, polyvinylchoride
materials, polycarbonate, polyethylene terephthalate (PET), poly
methyl methacrylate acrylic (PMMA), adhesive tape, and/or any
material having similar characteristics. The seal strip may be
formed by, for example, a molding process.
[0117] Referring to FIG. 5B, at least a portion of film 3 may be
coupled to second frame 4, or be placed between bottom cover 1 and
second frame 4, and may be configured to enable the user to view
and operate the enclosed portable electronic device. For example,
as shown in FIG. 5C, film 3 may be attached to the inner surface or
a flat part of second frame 4. In some exemplary embodiments, film
3 may include materials such as thermoforming plastics,
polyvinylchoride materials, polycarbonate, polyethylene
terephthalate (PET), poly methyl methacrylate acrylic (PMMA),
adhesive tape, and/or any other materials having similar
characteristics. Film 3 may be flexible but also may have an
enhanced strength so that it may withstand a water pressure under a
higher water resistance standard. As an example, film 3 may be
capable of withstanding a condition that is specified in the IPX7
standard, i.e., a water immersion for at least 30 minutes at a
depth of at least one meter. Film 3 may also be capable of
withstanding a condition of a higher IPX8 standard, i.e., a
continual submersion in water under conditions which are identified
by the manufacturer. As another example, film 3 may also be capable
of withstanding the IP65 standard.
[0118] Film 3 may also be a clear/transparent or substantially
clear/transparent water-resistant film so that a user can view the
screen or a substantial portion of the screen of the portable
electronic device. In addition, film 3 may also enable a user's
operation of the portable electronic device when it is enclosed in
case structure 3000. For example, some portable electronic devices
may have capacitive-type touch sensors that are incorporated in the
touch-point screens. A user may operate these portable electronic
devices by touching and/or moving a fingertip on the surface of the
touch-point screen. Film 3 may thus be a touch-sensitive or
transmissive film that enables the user to operate a touch-point
screen of the portable electronic device through film 3. As a
result, operations may be carried out without opening case
structure 3000. In other words, film 3 may enable the portable
electronic device to be operated when it is in a humid,
water-exposing condition, or under other conditions that require
the portable electronic device to be enclosed. One of ordinary
skill in the art would appreciate that film 3 may also be other
types of films that can enable operation of the portable electronic
device, such as resistance-sensitive films.
[0119] In some embodiments, film 3 may also be an anti-reflection
film, an anti-glare film, an anti-fingerprint film, a monitor
filtering film, and/or other similar films. For example, film 3 may
filter out the light reflected from the smooth glass surface of the
touchscreen device as well as the radiation emitted from the
portable electronic device. This may be used to protect the user's
privacy by decreasing the viewing angle of the touchscreen of the
portable electronic device. In addition, film 3 may also be able to
dissipate static electrical charge buildup. Film 3 may also be
polarized, colorized, or tinted, depending on the application.
[0120] A portable electronic device may have buttons or switches,
such as the "home" button on an Apple iPhone.RTM. 5 device.
Therefore, in some exemplary embodiments, film 3 may include a
corresponding convex or concave shape to enable convenient
operation of the portable electronic device. As an example, for an
Apple iPhone 5.RTM. device, film 3 may include a concave circle
near the bottom edge (not shown) for operating of the "home"
button. One of ordinary skill in the art would appreciate that the
concave circle may be positioned anywhere on film 3. In addition,
film 3 may include any number of shapes, buttons, membranes, etc.,
which may enable ease of operation of the portable electronic
device.
[0121] Referring to FIGS. 5B and 5C, in some embodiments, film 3
may be detachably or integrally coupled to a sealing area 40 of
second frame 4 through an attaching mechanism, such as a seal 8
shown in FIG. 5B. Seal 8 may be directly disposed on sealing area
40, such as a flat part, of second frame 4. Seal 8 may be a VHB
material. Seal 8 may also be formed by coating any colloidal
substances on sealing area 40 of second frame 4 to provide the
adhesion effect. Moreover, seal 8 may include an adhesive material
that is waterproof, such as waterproof up to one meter below the
water surface, or water-resistant, such as water-resistant to a
water-jet. In some embodiments, when the adhesive materials are
used, film 3 may not be replaceable. That is, replacing film 3 may
cause damage to film 3 and render it unusable. Thus, in these
embodiments, film 3 may be made of or combined with
strength-enhancing, anti-scratch, or anti-breaking material, so
that damage to film 3 may be reduced or eliminated. Film 3 may thus
have a longer life span. In some other embodiments, seal 8 may
allow film 3 to be replaced if it is scratched or damaged. Film 3
in these embodiments may have a shorter life span but may be
relatively inexpensive. In addition, seal 8 may also be configured
to be impact-absorbing so that it may prevent or reduce the
likelihood of damage caused by impact, impinge, shock, and/or drop
that are imposed at the second frame and/or film 3 of case
structure 3000.
[0122] FIG. 5D illustrates a partial, exploded view of case
structure 3000 of FIG. 5A. Referring to FIGS. 5B-5D, layer 10 may
be placed between bottom cover 1 and second frame 4. Layer 10 may
be detachably coupled to bottom 1, or integrated with bottom cover
1 so to form an integral piece. Layer 10 may substantially cover
the backside of the enclosed portable electronic device. In some
embodiments, layer 10 may have a flat back surface (not shown).
[0123] FIG. 5D illustrates an exploded view showing layer 10
separated from bottom cover 1 and first frame 2. Referring to FIG.
5D, in some embodiments, layer 10 may include additional
cushioning, which may have a convex-concave pattern with an
enhanced thickness at the convex area. The additional cushion of
layer 10 may be configured to provide additional impact absorption
or shock resistance. The additional cushioning may include a
material that is similar or different to that of layer 10. For
example, the material of the additional cushioning can be soft
rubber, plastic, TPE, thermoplastic polyurethane (TPU), and/or any
other material having similar characteristics. Furthermore, the
additional cushioning may be substantially transparent, opaque, or
reflective. For example, the additional cushioning may be
reflective so that sunlight can be reflected in order to prevent
protective case structure 3000 and the enclosed portable electronic
device from being exposed to excessive heat or an increased
temperature.
[0124] Referring to FIG. 5D, the additional cushioning of layer 10
may include one or more pyramid-shaped cushioning elements 151.
Pyramid-shaped cushioning elements 151 have a greater thickness at
their centers than at their edges. As a result, when an external
force or stress is applied to case structure 3000, the increased
thickness enables pyramid-shaped cushioning elements 151 to absorb
extra external force or stress and therefore enhances the
cushioning capability of case structure 3000. As a result, the
portable electronic device that is enclosed in case structure 3000
may receive additional protection against physical impact, stress,
shock, collision, etc.
[0125] Moreover, the material that is included inside
pyramid-shaped cushioning elements 151 may or may not be the same
as the material in other areas of pyramid-shaped cushioning
elements 151. For example, pyramid-shaped cushioning elements 151
may be filled with air or any other gas, so that case structure
3000 may have a reduced weight, while still providing additional
cushioning to the enclosed portable electronic device. One of
ordinary skill in the art would appreciate that the cushioning
elements may alternatively have any other shapes or form any other
patterns that are desired. The cushioning elements may also use any
material that may provide additional absorption of physical impact,
stress, and/or shock-resistance.
[0126] Referring to FIG. 5B, in some embodiments, first frame 2 may
further include a plurality of casing buttons, such as casing
buttons 42, 43a, 43b, and 44. Casing buttons 42, 43a, 43b, and 44
may be depressible and may be configured to operate their
respective underlying functioning mechanisms, such as a push
button, a key, a switch, a sliding control, a knob, or any other
control mechanism, of the portable electronic device. As an
example, the material of casing button 42 may include soft plastic,
such as polypropylene, soft rubber, and/or any other materials
having similar characteristics.
[0127] Referring to FIG. 5B, in some embodiments, casing button 42
may include an axis 421. When case structure 3000 is closed or
assembled, for example, casing button 42 may be detachably,
movably, or permanently coupled to or disposed in an opening 27
through axis 421. Axis 421 may enable coupling of casing button 42
in a manner that may allow casing button 42 to switch, move, slide,
tilt, and/or perform other similar motions. As an example, axis 421
may include a rotational axis and may be housed, coupled, or
gripped in a concave portion, slot, groove, and/or other similar
structures (not shown) in first frame 2. In some embodiments, such
structure may enable casing button 42 to engage in a motion as
described above to, for example, turn on and off a functional
button of the enclosed portable electronic device. In some
embodiments, such structure may itself move, slide, tilt, and/or
perform other similar motions to, for example, turn on and off a
functional button of the enclosed portable electronic device.
[0128] Referring to FIG. 5B, in some embodiments, casing buttons
43a, 43b, and 44 may also be detachably, movably, or permanently
coupled to or disposed in openings 28a, 28b, and 29 of bottom cover
1, respectively. In some embodiments, when case structure 3000
encloses the portable electronic device, openings 27, 28a, 28b, and
29 may correspond to the ring/mute switch button, the volume-up
button, the volume-down button, and the power button of the
portable electronic device, respectively. Therefore, a user may
operate the buttons of the portable electronic device (not shown)
by, for example, pressing on casing buttons 42, 43a, 43b, and 44 of
case structure 3000. One of ordinary skill in the art would
appreciate that case structure 3000 may also include any number of
openings and casing buttons corresponding to the underlying
functioning mechanisms. The openings and casing buttons may be
located, disposed, or arranged at any locations desired.
[0129] Referring to FIG. 5B, in some embodiments, first frame 2 may
further include openings 22 and 23. Openings 22 and 23 may be
placed, for example, corresponding to the positions of an earphone
jack and a charging and communication connector of the portable
electronic device, respectively. Therefore, when the portable
electronic device is accommodated, housed, or enclosed in case
structure 3000, openings 22 and 23 may enable a user to operate the
earphone function and charging function of the portable electronic
device without the need to remove the portable electronic device
from case structure 3000.
[0130] Referring to FIG. 5B, in some embodiments, bottom cover 1
may include an opening 221 corresponding to opening 22 of first
frame 2. Case structure 3000 may also include cap 9. In some
embodiments, cap 9 may have a shape corresponding to that of
opening 22 and a dimension that is similar or slightly smaller than
that of opening 22. As a result, when bottom cover 1 and first
frame 2 are coupled together, cap 9 of case structure 3000 may pass
through opening 221 of bottom cover 1, and snugly plug or insert
into opening 22 of first frame 2. Cap 9 may thus be configured to
seal opening 22 and provide, for example, substantial waterproof or
water-resistant capability. As another example, opening 22 and cap
9 may each include screw threads and therefore, cap 9 may be
coupled to, inserted into, or screwed into opening 22 through the
engaging of the screw threads. One of ordinary skill in the art
would appreciate that cap 9, opening 221, and opening 22 may
include any structure desired. For example, in some embodiments,
cap 9 may not be separated from and may instead be integrated with
first frame 2 or bottom cover 1, such as by a connector (not
shown), so that unintentional misplacement of cap 9 may be avoided.
Furthermore, one of ordinary skill in the art would appreciate that
the coupling mechanism of cap 9, opening 221, and opening 22 is not
limited to those described above and may include any other similar
mechanisms.
[0131] Referring to FIG. 5B, in some embodiments, bottom cover 1
and second frame 4 may each include a carrying mechanism, such as
an opening 55a and an opening 55b, respectively. When each bottom
cover 1 and second frame 4 include a carry mechanism, the carry
mechanisms may correspond to each other. For example, as shown in
FIG. 5B, opening 55a and opening 55b may correspond to each other
near the same corner of case structure 3000. Therefore, when the
bottom cover 1 and second frame 4 are coupled to each other (e.g.,
when case structure 3000 is closed), opening 55a and opening 55b
may form a single hole configured to receive a lanyard, and thus
enable case structure 3000 to be attached to other objects carried
by a person via a hanging or carrying mechanism, such as a rope, a
band, a belt, a string, a hook, and/or any other similar carrying
mechanisms. One of ordinary skill in the art would appreciate that
case structure 3000 may include any number of openings, such as
openings 55a and 55b, located anywhere on case structure 3000. For
example, in some embodiments, case structure 3000 may only include
one of openings 55a and 55b.
[0132] Referring to FIG. 5B, bottom cover 1 may further include
lens protecting structure 16, which may include first structural
element 161 and second structural element 162. First frame 2 may
also include opening 19 corresponding to lens protecting structure
16 of bottom cover 1. In addition, case structure 3000 may further
include a lens 165. Lens 165 may be disposed in opening 19. For
example, lens 165 may have a size that is similar to or slightly
smaller than opening 19, and thus, may be snugly disposed, placed,
or inserted in opening 19. In some embodiments, when lens
protecting structure 16, opening 19, and lens 165 are coupled
together, case structure 3000 may provide protection of the camera
lens of the enclosed portable electronic device. In some
embodiments, first structural element 161 and second structural
element 162 of lens protecting structure 16 may correspond to the
camera lens and the flash functions of the portable electronic
device, respectively. In some embodiments, lens 165 may include a
double anti-reflective coating for providing a high-transparency
feature, thereby enabling lens 165 to be anti-reflective. An
anti-reflective coating may enable, for example, the portable
electronic device to obtain improved picturing effect and result.
One of ordinary skill in the art would appreciate that lens 165 may
also have any other coating desired, such as anti-glare and
anti-scratch coatings.
[0133] FIG. 6A illustrates a perspective view of another exemplary
case structure 4000. FIG. 6B illustrates an exploded view of case
structure 4000 of FIG. 6A. Referring to FIGS. 6A and 6B, case
structure 4000 is provided for housing or enclosing a portable
electronic device (not shown), such as an tablet PC like Apple
iPad.RTM. mini, and therefore enables preventing or reducing the
likelihood of shock/drop/impact-, water-, dust-, and/or
chemical-damage of the portable electronic device. Case structure
4000 may be substantially waterproof or water-resistant, such as
substantially waterproof in compliance with class IP65 according to
the U.S. National Electrical Manufacturers Association rating. The
types of portable electronic devices that are capable of being
enclosed in case structure 4000 may include, but are not limited
to, a cell phone, a smart phone, an MP3 player, a portable
computer, a tablet PC, a personal digital assistant, or any other
similar devices.
[0134] Referring to FIGS. 6A and 6B, according to some embodiments,
case structure 4000 includes bottom cover 1, first frame 2, film 3,
second frame 4, and layer 10. In some embodiments, first frame 2
may be detachably coupled to bottom cover 1. Layer 10 may be placed
between bottom cover 1 and first frame 2. Layer 10 may also form an
integral piece with bottom cover 1. Second frame 4 may be
detachably coupled to or integrated with first frame 2 so as to
form a single piece. Film 3 may be placed between second frame 4
and first frame 2. In some embodiments, the dimensions of bottom
cover 1 and second frame 4 may be substantially the same or
similar. In some embodiments, the dimensions of first frame 2 may
be substantially similar or slightly smaller than bottom cover 1
and/or second frame 4 so that it may be coupled to or accommodated
by bottom cover 1 and second frame 4. Referring to FIG. 6A, case
structure 3000 is illustrated in an assembled condition, and thus,
some elements of case structure 3000 may not be marked or labeled
in FIG. 6A. The material of each element of the case structure 4000
may be the same or similar to those described in connection with
case structure 3000 and will not be described here.
[0135] FIG. 6C illustrates another exploded view of case structure
4000 of FIG. 6A. Referring to FIG. 6C, in some embodiments, first
frame 2 may be formed or integrated with bottom cover 1 and
therefore formed as an integral single piece (together shown as
bottom cover 1 in FIG. 6C). As shown in FIG. 6C, second frame 4 may
be detachably coupled to or assembled with bottom cover 1 (and the
integrated first frame 2).
[0136] Referring to FIGS. 6B and 6C, bottom cover 1 may include a
plurality of, such as four, coupling structures 32, which may be
placed at a plurality of, such as four, edges of bottom cover 1.
Correspondingly, second frame 4 may include a plurality of, such as
four, engaging portions 34, and engaging portions 34 may be placed
at the plurality of, such as four, edges of second frame 4.
Coupling structures 32 and engaging portions 34 may be configured
to enable bottom cover 1 and second frame 4 to be hingedly,
rotatably, movably, permanently, detachably, latchably, and/or
snugly coupled or engaged to prevent or reduce the likelihood of
undesirable separation of case structure 4000. For example,
coupling structures 32, such as latches and engaging portions 34,
such as corresponding latching slots, as shown in FIG. 6B, may
enable a user to close or assemble case structure 4000 and
therefore enclose a portable electronic device. One of ordinary
skill in the art would appreciate that positions of coupling
structures 32 and engaging portions 34 shown in FIG. 6B are for
illustration purpose and are not limiting. For example, coupling
structures 32 and engaging portions 34 may be placed in other
external edges of case structure 4000. One of ordinary skill in the
art would appreciate that coupling structures 32 may also be
attached to engaging portions 34 by any means.
[0137] Referring to FIGS. 6B and 6C, in some embodiments, coupling
structures 32 may include an axis 321. Coupling structure 32 and
axis 321 may be the same or similar to those shown in FIGS. 5B and
5C, and thus will not be described here.
[0138] Referring to FIGS. 6B and 6C, in some embodiments, second
frame 4 may include a groove 14 surrounding at least a portion of
the periphery of second frame 4. First frame 2 shown in FIG. 6B (or
the integrated bottom cover 1 shown in FIG. 6C) may include a
convex portion 20 corresponding to groove 14 of second frame 4.
Groove 14 may include a plurality of coupling portions 431, such as
latches, hooks, protrusions, bars, and/or similar engaging or
coupling portions. Convex portion 20 may include a plurality of
engaging elements 432 (shown in FIGS. 6B and 6C), such as latches,
hooks, protrusions, bars, and/or similar engaging portions. Groove
14, convex portion 20, coupling portions 431, and engaging elements
432 may be the same or similar to those shown in FIGS. 5B and 5C,
and thus will not be described here.
[0139] In some embodiments, groove 14 may further include a seal
strip (not shown) configured to provide additional or enhanced
water-sealing or water-resistance capability of the water-sealing
or water-resistant structure as discussed above. The seal strip may
be the same or similar to those shown in connection with case
structure 3000, and thus will not be described here.
[0140] Referring to FIG. 6B, at least a portion of film 3 may be
coupled to second frame 4, or be placed between bottom cover 1 and
second frame 4, and may be configured to enable the user to view
and operate the enclosed portable electronic device. Film 3 may be
the same or similar to those shown in connection with case
structure 3000, and thus will not be described here.
[0141] Referring to FIGS. 6B and 6C, in some embodiments, film 3
may be detachably or integrally coupled to a sealing area 40 of
second frame 4 through an attaching mechanism, such as a seal 8
shown in FIG. 6B. Seal 8 may be the same or similar to those shown
in connection with case structure 3000, and thus will not be
described here.
[0142] FIG. 6D illustrates a partial, exploded view of case
structure 4000 of FIG. 6A. Referring to FIGS. 6B and 6D, in some
embodiments, layer 10 may be disposed or coupled between bottom
cover 1 and first frame 2, and may substantially cover the backside
of the enclosed portable electronic device. Layer 10 may be the
same or similar to those shown in connection with case structure
3000, and thus will not be described here.
[0143] Referring to FIG. 6B, in some embodiments, first frame 2 may
further include a plurality of casing buttons 52 and 53. Casing
buttons 52 and 53 may be depressible and may be configured to
operate the underlying functioning mechanisms, such as push
buttons, keys, switches, sliding controls, knobs, or other control
mechanisms of the portable electronic device. As an example, the
material of casing buttons 52 and 53 may include soft plastic, such
as polycarbonate, polypropylene, soft rubber, and/or any other
material having similar characteristics. In some embodiments, when
case structure 4000 is enclosed, for example, casing buttons 52 and
53 may be detachably, movably, or permanently coupled to or placed
in openings 17 and 18 of bottom cover 1.
[0144] Referring to FIG. 6B, in some embodiments, bottom cover 1
may also include an opening 30 corresponding to a casing button 71
configured to provide substantial sealing of case structure 4000
and therefore substantial isolation of the enclosed portable
electronic device. In some embodiments, when case structure 4000
encloses the portable electronic device, openings 17, 18, and 30
may correspond to the power button, the volume button, and the
ring/mute switch button of the portable electronic device,
respectively. Therefore, a user may operate the buttons of the
portable electronic device (not shown) by, for example, pressing on
casing buttons 52, 53, and 71 of case structure 4000. As another
example, a user may operate the ring/mute switch button of the
portable electronic by pulling out or detaching casing button 71
from opening 30, and therefore exposing the ring/mute switch for
operation. One of ordinary skill in the art would appreciate that
case structure 4000 may also include any number of openings and
casing buttons corresponding to the underlying functioning
mechanisms. The openings and casing buttons may be located,
disposed, or arranged at any locations desired.
[0145] Referring to FIG. 6B, in some embodiments, first frame 2 may
further include openings 22 and 23. Opening 22 and opening 23 may
be located corresponding to the positions of an earphone jack and a
charging and communication connector of the portable electronic
device, respectively. For example, corresponding to an Apple
iPad.RTM. mini device, openings 22 and 23 may be located at top
side 81 and bottom side 21 of the first frame 2, respectively.
Therefore, when the portable electronic device is accommodated,
housed, or enclosed in case structure 4000, opening 22 and opening
23 may enable a user to operate the earphone function and charging
function of the portable electronic device without the need to
remove the portable electronic device from case structure 4000.
[0146] Referring to FIG. 6B, in some embodiments, bottom cover 1
may further include an opening 82 corresponding to opening 22 of
first frame 2. Case structure 4000 may also include a cap 9. In
some embodiments, cap 9 may have a shape corresponding to that of
opening 22 and a dimension that is similar or slightly smaller than
that of opening 22. As a result, when bottom cover 1 and first
frame 2 are coupled together, cap 9 of case structure 4000 may pass
through opening 82 of bottom cover 1, and snugly plug or insert
into opening 22 of first frame 2, to seal opening 22 and to
provide, for example, substantial waterproof or water-resistant
capability. As another example, opening 22 and cap 9 may also
include screw threads and therefore, cap 9 may be coupled to,
inserted into, or screwed into opening 22 through the engaging of
the screw threads. One of ordinary skill in the art would
appreciate that cap 9, opening 82, and opening 22 may include any
structure desired. For example, in some embodiments, cap 9 may not
be separated and may instead be integrated with bottom cover 1
and/or first frame 2, such as by a connector (not shown), so that
unintentional misplacement of cap 9 may be avoided. Furthermore,
one of ordinary skill in the art would appreciate that the coupling
mechanism of cap 9, opening 82, and opening 22 is not limited to
those described above and may include any other similar
mechanisms.
[0147] Referring to FIG. 6B, bottom cover 1 may further include
lens protecting structure 54. First frame 2 may also include
opening 19 corresponding to lens protecting structure 54 of bottom
cover 1. In addition, case structure 4000 may further include lens
541. Lens 541 may be coupled to or placed in opening 19. For
example, lens 541 may have a size that is similar to or slightly
smaller than opening 19, and thus, may be snugly disposed, placed,
or inserted in opening 19. In some embodiments, when lens
protecting structure 54, opening 19, and lens 541 are coupled
together, case structure 4000 may provide protection of the camera
lens of the enclosed portable electronic device. In some
embodiments, lens 541 may include a double anti-reflective coating
for providing a high-transparency feature, thereby enabling lens
541 to be anti-reflective. An anti-reflective coating may enable,
for example, the portable electronic device to obtain improved
pictures. One of ordinary skill in the art would appreciate that
lens 541 may also have any other coating desired, such as
anti-glare and anti-scratch coatings.
