Continuation-in-Part of U.S. patent application Ser. No.
10/441,928, filed May 19, 2003, which is a Continuation-in-Part of
U.S. Design patent application Ser. No. 29/163,110, filed Jun. 26,
2002, now U.S. Pat. No. D478,418, each application being
incorporated herein by reference in its entirety.
FIELD OF THE INVENTION
[0002] The present invention relates to multi-piece fasteners,
clips and buckles, and more specifically a device adapted to
selectively retain an electric device or other apparatus, and which
can be released by a rotational movement.
BACKGROUND OF THE INVENTION
[0003] Cellular telephones, pagers, radios, personal digital
assistants (PDAs), and other similar electronic devices
(hereinafter "electronic device") have become increasingly popular,
with many people securing these devices on their belts or pockets.
The inevitable advances in technology will surely bring about new
items that users will desire to carry in this fashion SO that they
are easily accessible.
[0004] Various means of clipping small items to a user's belt have
been in use for many years. More specifically, U.S. Pat. No.
5,779,115, assigned to NOKIA.RTM., teaches a carrying device that
employs a hand-operated slide that includes an element to deflect a
spring to release a lock. The device employs a button, and a
cylindrical stem interconnected to a circular plate that is sewn on
a case adapted to receive a cellular phone. The body portion of the
holding device is attached to a user's belt and employs a locking
feature. The user inserts the button into the lock which thus
secures the electronic device on the belt. To disengage the
electronic device from the carrying device, the user must release
the locking mechanism by deflecting a release mechanism. This type
of lock has the disadvantage of being assembled from many parts
thus time consuming and expensive to manufacture. Further, the
release mechanics of traditional locks maybe inadvertently
activated causing the item to become dislodged and possibly damaged
in a fall. Failure, due to normal wear and tear, of the locking
spring and the clip housing are also common, which will cause the
electronic device to become dislodged from the locking mechanism
and possibly damaged. Finally, it is cumbersome and awkward in
certain situations to disengage the lock with a thumb or finger,
and it is often difficult for the elderly or physically challenged
to perform the unlocking operation.
[0005] Separable fasteners with a single piece locking feature are
known in the art. For example, the MOD-U-LOCK.RTM. attachment
system, built by the National Molding Corporation and sold
commercially by DURAFLEX.RTM., is a separable fastener that
utilizes the elastic properties of plastic to lock the button into
place. The locking portion includes a flexible tab with a locking
lip and a pocket to receive the button, which may be released by
applying finger pressure against an upper portion of the tab.
However, the locking portion of this type of separable fasteners is
usually rigidly interconnected onto existing materials, and thus
provides no means for removable interconnection to a belt, pocket,
or other object.
[0006] Another drawback of the separable fasteners is that they
have limited applications outside use with soft compliant items.
More specifically, user-applied deflects the tab to provide a
sufficient gap so that the button, which is interconnected to the
device, may be easily slipped into and out of the locking mechanism
without interference with a locking lip on the tab. In current
low-profile lock designs, a deflected tab will come in contact with
the item the lock is attached to. If the lock is attached to a
compliant item, a nylon bag for example, pressure from the tab will
deflect the compliant item and a sufficient gap will be provided
for button disengagement. If the item that the locking portion of
the separable fastener is interconnected to is not compliant, the
deflected tab may not provide a sufficient gap for the insertion or
removal of the button. Fasteners in use today are low profile, and
as such lack a sufficient gap when deflected to be used on
non-compliant materials.
[0007] There is thus a significant need for a one-piece integrally
molded interconnection system that may be selectively attached to a
belt or pocket, and which comprises a locking mechanism that
selectively secures an electronic device, and wherein selective
rotation of the electronic device facilitates disengagement
thereof. There is a further need for a simplistic interconnection
system which requires no assembly, is durable, and can be used in a
multitude of applications.
SUMMARY OF THE INVENTION
[0008] It is thus one aspect of the present invention to provide a
detachable fastener that selectively interconnects to a user's belt
and selectively secures an electronic device, while eliminating
post-manufacturing steps of assembly and the costs associated
therewith. Thus, the detachable fastener of one embodiment of the
present invention does not employ springs or other means to
disengage the lock.
[0009] It is another aspect of the present invention that the
single piece design be light, strong, and less susceptible to
breakage and jamming due to the reduction of movable parts. Also,
the single piece design will have no metal parts that are generally
prone to corrosion and tend to activate metal detectors. Due to the
single piece design and the elimination of post manufacturing
steps, significant time and expense is saved.
[0010] It is a further aspect of the present invention to provide a
fastener that has a robust design, and which can readably changed
with a revision of a mold. Thus, the shape and design of the
fastener may be changed easily, as well as the color. In addition,
the fastener may be molded with substantially planar areas for the
attachment of company logos or other advertisements, or the desired
indicia may be etched or molded directly onto the clip.
[0011] It is another aspect of the present invention to provide a
separable fastener that includes a button that selectively
interconnects with a locking portion of the separable fastener by
sliding into a locking pocket thereof. The button may be
interconnected to any number of electronic devices, tools, or
carrying pouches, sleeves, or holsters, such as a cell phone, a
pager, a PDA, an MP3 player, a CD player, a diagnostic device, a
radio, tape cassette player, a health monitor, a hammer, a tape
measure, an inventory device, a water bottle, a flashlight, a
sleeve or holster adapted to secure a cell phone, a gun holster, a
pouch, a hand cuff holder, a knife case, and a time piece
(hereafter "electronic device"). Alternatively, the button may be
interconnected to a belt, strap, leash, or any other object that is
designed to selectively interconnect to a mating fastener.
Generally, the attachment of the button to the electronic device or
other item depends on the application, but the button may be sewn,
glued, integrally molded, screwed, riveted, clipped, taped, or tied
to the item, as appreciated by one skilled in the art. Finally,
items of the same general size may fit into the same lock depending
on the shape of the interface portion of the lock and the
button.
[0012] It is yet another aspect of the present invention to provide
a belt clip that is integrally interconnected to the locking
portion of the separable fastener by a thinner, resiliently
deflectable, section of material. By squeezing together finger and
thumb tabs on the clip and lock, the thinner section will
resiliently deflect, thereby allowing selective interconnection to
a user's belt. The lock portion will generally use the same
materials, such that the tab attached to the locking portion may be
easily deflected to allow insertion and removal of the button that
is interconnected to the electronic device.
[0013] It is a related aspect of the present invention to provide a
locking portion of the integrai assembly that is attached to the
belt clip via a spring and pin combination, and thus does not
utilize the one-piece integral design discussed above, but is still
simplistic to manufacture, and thus cost effective.
[0014] It is still yet another aspect of the present invention to
provide a holder used to carry larger items that, due to their
shape and/or size, a user would find difficult to disengage the
lock of the fastener. In this embodiment, the locking portion
employs the locking pocket, but no movable tab. In contrast, the
locking portion is equipped with a small protrusion that in turn
interfaces with a tab on the button. Disengagement is achieved by
flexing the tab, thereby releasing the interface. In addition, the
interconnection between the clip and the locking portion may not
include a reduced thickness, but rather employ the same dimensions
as the joined components to increase the strength of the holder to
accommodate heavier items.
[0015] In each of the above mentioned aspects of the invention, a
button that is selectively interconnected to the electronic device
or other items is employed. The interface portion of the button
will dictate the mobility of the item when it is installed in the
locking pocket. For example, a round interface will allow the
device to rotate, whereas a square interface will constrain the
device to prevent rotation, and an interface that is notched will
allow the user to maintain a desired rotation angle in a preferred
position of use.
[0016] It is another aspect of the present invention that there be
a sufficient gap incorporated into the locking portion of the
integral assembly such that sufficient space is provided for the
tab to be deflected.
[0017] It is still yet another aspect of the invention to provide a
button that is selectively removable from the locking portion when
it is rotated to a predetermined angle, thus removable without
manually deflecting the tab. In one embodiment of the present
invention the button employs an angled bevel on the interface
portion that provides sufficient clearance from the locking portion
of the clip or facilitates hands-free deflection of the tab when
the button is rotated a predetermined angle. During insertion, the
beveled area of the button travels in an unobstructed path, or in a
path that facilitates deflection of the tab, into the locking
portion of the clip. Further, once the button is seated securely in
the pocket, a non-beveled area of the button will be in contact
with the locking portion, thereby preventing removal. Removal of
the electronic device is achieved by rotation, in one embodiment
about 180 degrees, such that the beveled area is again proximate to
the locking portion, thereby providing an unobstructed or tab
deflecting path for button removal. One skilled in the art will
appreciate that any rotation angle, or plurality thereof, may be
used to facilitate button removal.
[0018] The locking portions of the present invention that are
resiliently deflectable, may be used. Alternatively, a locking
portion with no moving parts may be employed. More specifically, a
beveled button may be employed that alleviates the need for a
resiliently deflectable tab by providing an unobstructed path for
selective interconnection. Further, the removal of the resiliently
deflectable tab will allow the locking portion to be constructed
with a lower profile, because the travel distance of the tab will
no longer be required.
[0019] It is yet another aspect of the present invention to provide
a fastening mechanism that is not used exclusively with electronic
devices. More specifically, one embodiment of the present invention
may be used with other items, such as belts, straps, leashes, or
any other similar type of device. For example, the button may
interconnect to an intermediate appendage that includes at least
one aperture for the interconnection to the strap or belt. It is
envisioned that this embodiment be used for straps or belts for
elderly or disabled individuals such that the interconnection and
disconnection of the separable fastener is facilitated.
[0020] It is related aspect of the present invention to provide a
button that includes a second bevel or relief to ensure that the
button does not disengage from the lock. More specifically, as
previously described above, the non-beveled portion is designed to
selectively engage the locking lip on the resiliently deflectable
tab of the locking portion of the clip. However, over time this
engagement may become worn such that the button may become
disengaged from the locking portion upon sufficient pressure
thereto. Accordingly, one embodiment of the present invention
includes a locking tab that includes a locking cavity integrated
therein. A button with a locking relief is also provided such that
the locking relief and the locking cavity engage when the button is
in a locked position such that disengagement from the locking
portion of the severable fastener is subsequently prevented.
Additional advantages of the present invention will become readily
apparent from the following discussion, particularly when
incorporated with the accompanying drawings.
[0021] Thus, in one aspect of the present invention a fastening
system adapted for selectively securing an electronic device is
provided comprising:
[0022] a locking portion comprising an upper end, a lower end and
lateral edges extending therebetween;
[0023] a receiving pocket positioned within said locking portion
and comprising at least one outwardly extending lip on a first end
with a restricted diameter upper surface;
[0024] a button having a lower surface and an upper surface to
define a first thickness, said button further including:
[0025] a beveled edge extending generally between said lower
surface and said upper surface of said button, wherein said first
thickness is reduced and
[0026] a locking relief extending generally between said lower
surface and said upper surface of said button, generally opposite
said beveled edge, wherein said first thickness is reduced; and
[0027] wherein said receiving pocket is sized to receive and secure
said button in a first position, but said button cannot be
withdrawn from said receiving pocket until said beveled edge is
positioned substantially adjacent to said outwardly extending
lip.
[0028] The Summary of the Invention is neither intended nor should
it be construed as being representative of the full extent and
scope of the present invention. The present invention is set forth
in various levels of detail in the Summary of the Invention as well
as in the attached drawings and the Detailed Description of the
Invention and no limitation as to the scope of the present
invention is intended by either the inclusion or non-inclusion of
elements, components, etc. in this Summary of the Invention.

DETAILED DESCRIPTION
[0109] Referring now to FIGS. 1-37, a separable fastener that
includes at least a locking portion and a button is shown. One
embodiment of the present invention includes a locking portion with
a resiliently deflectable tab that employs a locking protrusion
that is adapted to selectively engage the button. Engagement and
disengagement of the button is achieved by selectively deflecting
the tab to provide a obstruction-free path for the button to
travel. Alternatively, in another embodiment of the invention, a
button is provided that employs a beveled area that is adapted to
provide an obstruction free path, or alternatively a button that
provides the tab deflection force, for removal when the beveled
area is rotated to a predetermined angle.
[0110] Referring now to FIGS. 1-4, one embodiment of the present
invention is shown herein. In general, a one-piece integral belt
clip holder 60 is a union of a belt clip 10 and a locking portion
30 of a separable fastener which are attached by a web 31 of
plastic or other material with resilient properties, made from a
material such as rubber, deflectable plastic, etc. The web 31 is
resilient to allow for attachment to a belt when pressure is
applied to the finger grip on the clip portion 12 and the finger
grip on the lock portion 13. Alternatively, the lower portions of
the belt clip 10 and the locking portion 30 may be pulled apart to
allow for selective interconnection to a belt or other object. The
lock portion 30 employs a flexible plastic tab 15 with a lip 16
that secures a button and prevents upward movement and
disengagement from the lock portion 30. Alternatively, other types
of residual materials commonly known in the art may be used,
including rubber, polyethylene, etc. A locking pocket 19 constrains
the button portion of the separable fastener, and consists of a
front wall 17, a back wall 18, and side pocket walls 22. When the
tab 15 is flexed, the non-locking portion remains supported in the
pocket and is easily disengaged. The belt clip portion 10 may be
equipped with a hook 11 which will help maintain the unit on the
user's belt. Both portions of the belt clip 10 and the locking
portion 30 of the separable fastener are integrally molded
preferably with open molded spaces 14 and 21 which eliminates
assembly, inherent labor costs, and the expenses related
thereto.
[0111] Referring now to FIGS. 5-7 and FIGS. 26-27, a secondary
engaged portion of the separable fastener is shown, and which is
designed for interconnecting to an electric device such as a
cellular phone, radio, etc. This item is referred to herein as a
button 42, and is generally comprised of a plastic material such as
polypropylene, polyethylene, etc. The button's attachment surface
41 is connected to the button 42 by a stem 46 such that the button
42 is easily slipped into the pocket of the lock. In one
embodiment, the interconnecting stem 46 and/or the attachment area
41 may be made of rubber or other resilient material capable of
deflection which will decrease stresses on the button and
electronic device interface when a force is applied to a portion of
the electronic device. The stem 46 is not limited to a cylindrical
shape. For example, a rectangularly shaped stem 46 may be used
which would provide resiliency in one direction and greater
stiffness in the others. Also, at the button-to-electronic device
interface, a resilient material will provide a better bond between
the button attachment surface 41 and the electronic device because
the resilient material will be capable of deflection and
conformance to the electronic device that may have a non-planar
shape. The button 42 dictates the mobility of the item when it is
locked in the pocket. More specifically, a square shape will give a
user substantially no rotation, while a round button shape will
allow for substantially free rotation. Alternatively in one
embodiment, notches 43 may be employed to provide a variety of
fixed positions depending on the preferred application.
[0112] The button attachment surface 41 is selectively
interconnected to the electronic device, electronic device carrying
case, or other item by sewing, gluing, integrally molding,
clipping, screwing, riveting, taping, or tying. The button
attachment surface 41 may further employ a rivet hole 45 or
stitching holes 44 to facilitate interconnection with the
electronic device, electronic device carrying case, or other item.
One embodiment of the present invention is adapted for
interconnection to a sleeve or holster that secures a cellular
phone, wherein the sleeve encompasses all or a portion of the
cellular phone body.
[0113] Referring now to FIG. 8, the locking function of one
embodiment of the present invention is illustrated herein. More
specifically, the button 42 is shown interconnected to the
electronic device 50, while the integral belt clip and holder 60 is
shown with a tab 15 in the locked position. To lock the electronic
device 50 into place, the user applies pressure to the tab 15 in
the direction of the clip portion 10 of the integral assembly 60.
Alternatively embodiments may employ release mechanisms that are
pushed in different directions of release. After pressure is
applied to the tab 15, there is an unobstructed path for the button
42 to engage the pocket 19. That is, the button interface 42 is
easily guided downward into the locking pocket 19. When the user
releases the pressure on the tab 15 the locking portion of the tab
16 will prevent the button interface 42 from traveling upward.
Thus, the electronic device 50 is released by the application of
pressure to the tab 15 towards the clip portion 10 of the integral
assembly 60, thereby deflecting the tab, separating the lock 16 and
button interface 42, and providing an unobstructed path in which
the electronic device can travel.
[0114] The requisite pressure that deflects the tab 15 prior to the
introduction of the button interface 42 into the pocket 19 can be
supplied by the interface 42 itself. More specifically, the user
can initiate the downward motion of the electronic device 50 into
the pocket 19 without touching the tab 15. Thus, the contact of the
interface 42 with the tab 15, along with the downward force
supplied by the user, may sufficiently deflect the tab 15 so that
the interface 42 will engage the locking pocket 19.
[0115] Referring now to FIG. 9, the button 42 is shown
interconnected to the electronic device 50, while the belt clip 10
is attached to the user's 5 belt. The tab 15 of the lock 30 has
been deflected towards the user 5, while the button interface has
been seated in the locking pocket 19, and the tab 15 has been
released. Thus, the button is prevented from upward motion by the
lock 16, and the electronic device 50 is operably interconnected to
belt clip and holder 60.
[0116] Referring now to FIGS. 10-14, another embodiment of the
present invention is shown. This embodiment is similar to the first
embodiment of the present invention shown in FIGS. 1-9, but the
single piece molding is modified to simplify manufacturing because
"side pulls" on the mold are not required. In some molding
processes side pulls are required to form holes or cavities into
the final product. By deleting the need for side pulls, an integral
design is moldable using a two-piece mold construction, and more
clips can be made using a single mold. The requirement of side
pulls adds complexity and cost to the molding operation. More
specifically, the belt clip portion 10 is constructed slightly
longer than the locking portion 30. In addition, the belt clip
finger grip is split into two pieces 12A and 12B.
[0117] Referring now to FIG. 15, yet another embodiment of the
present invention is shown that employs a pin 7 and spring
mechanism to connect the locking 30 and clip 10 portions of the
unit. More specifically, the pressure on the finger grips 12 and 13
is reduced by the use of a pin and spring such that selective
interconnection to a user's belt or other object is more easily
performed.
[0118] Referring now to FIGS. 16-20, an alternate embodiment of the
present invention is shown that is more durable and which may be
used for larger items such as radios, CD players, PDAs, inventory
devices, water bottles, etc. In this embodiment of the present
invention, the locking feature 3 on the integral assembly 60 is not
attached to a flexible tab. Instead, the locking portion 30 employs
a small protrusion 3, which interfaces with a flexible tab 2 on the
button 42 when the button is seated in the locking pocket 19 and
the tab 2 is released. Further, the halves are connected by a
thicker interface 32 that increases the strength of the unit.
[0119] Referring now to FIG. 21, the locking function of one
embodiment of the present invention is illustrated herein. More
specifically, the button 42 is shown interconnected to a sleeve 36
on a larger device 50, while the integral belt clip and holder 60
is shown with a stationary locking protrusion 3. The sleeve 36 may
be used to selectively secure the larger device 50 to the button 42
if attachment locations on the item 50 are not feasible. To lock
the device into place the user applies pressure to the tab 2 on the
button 42. After pressure is applied to the tab 15 there is an
unobstructed path for the button 42 to engage the pocket 19, that
is, the button 42 may be easily guided downward into the lock
pocket 19. When the user releases the pressure on the tab 2, the
locking portion of the integral assembly 3 will prevent the button
42 from traveling upward because a portion of the tab 2 will
selectively interconnect with the lock 3. The item is released by
the application of pressure to the tab 2 thereby deflecting the
tab, separating the lock 3 and the tab interface 4, and providing
an unobstructed path in which the device can be moved upward.
[0120] The requisite pressure that deflects the tab 2 prior to the
introduction of the button interface 42 into the pocket 19 can be
supplied by the interface 4 itself. More specifically, the user can
initiate the downward motion of the device into the pocket without
touching the tab 2. The contact of the interface 4 with the lock 3,
along with the downward force supplied by the user, will
sufficiently deflect the tab 2 so that the button interface 42 will
be able to be seated into the pocket 19.
[0121] Referring now to FIG. 22, the button 42 is shown
interconnected to the larger device 50, while the belt clip 10 is
attached to the user's 5 belt. The tab 2 of the button 42 has been
flexed towards the device 50, the button interface has been seated
in the pocket 19, the tab 2 has been released, and the button has
been prevented from upward motion by the contact of the interface 4
with the lock 3.
[0122] Referring now to FIGS. 23-25, another embodiment of the
present invention is shown that employs a thick connection
interface 32, but is substantially similar to the first two
embodiment described with respect to the aspects of the locking
feature. In order for any locking mechanism to work properly in
some embodiments of the present invention, a gap 70 must be
integrated into the locking portion 30 of the integral design to
allow unrestricted travel of the locking tab 15. This gap 70 will
extend from the back surface of the locking portion 71 to the back
wall of the locking pocket 18A. When the user deflects the tab 15,
the gap 70 will provide sufficient deflection of the tab 15 so that
the button 42 will not come in contact with the locking lip 16 when
a user inserts and removes a device from the integral assembly 60.
The greater the gap 70, the easier and quicker the button can be
inserted and released from the pocket and lock.
[0123] Referring now to FIG. 29, a "hard stop" is shown. As used
herein, a hard stop 1 is any type of backing material, detent, or
other mechanism which prevents the tab 15 from extending or
deflecting past a predetermined position. The predetermined
position may be dictated by the maximum deflection the tab 15 can
move without incurring damage. To engage and disengage a button
from the integral assembly 60, a user must depress the tab 15
toward the belt clip 10 of the integral assembly. Extreme
deflections of the tab 15 may fatigue the material such that it
will be permanently deformed or break. In order to prevent this
detrimental effect, the hard stop 1 may be added to the belt clip
portion 10 of the integral assembly 60. When a user applies
pressure on the tab 15 towards the belt clip portion 10, the tab 15
will deflect enough for engagement or disengagement of a button,
but the tab 15 will be stopped from further deflection when it
comes in contact with the hard stop 1. Preferably, the hard stop 1
is molded integrally with the belt clip 10.
[0124] Further, the hard stop 1 may be added to or molded onto the
tab 15 of the locking portion 30 of the integral assembly 60 as
opposed to the belt clip 10, as discussed above. When a user
applies pressure on the tab 15 towards the belt clip portion 10,
the tab 15 will deflect enough for engagement or disengagement of a
button, but the tab 15 will be stopped from further deflection when
the hard stop 1 on the tab 15 comes in contact with the belt clip
portion 10.
[0125] Referring now to FIGS. 30-32, an alternate embodiment of the
present invention is shown herein. More specifically, a button 42
that employs a beveled area 73 is shown that is adapted to
selectively interconnect with the lock portion 30 of the clip 60.
When interconnecting, the beveled area 73 allows the button 42 to
pass unobstructed into the locking pocket 19. However, one skilled
in the art will appreciate that deflection of the tab may be
facilitated by the angled bevel area 73, wherein hands-free
interconnection and disconnection is realized. Once seated in the
locking pocket 19, the button's 42 non-beveled area selectively
interconnects with the locking protrusion 3 of the locking portion
30, thereby preventing removal. To separate the button 42 from the
locking portion 30, the user rotates the button 42, such that the
beveled area 73 is proximate to the locking protrusion 3, thereby
providing an unobstructed path for the button 42 to travel. In
contrast to the previously-described embodiments, this embodiment
requires no manual deflection of the tab employed on the clip. More
specifically, the shape of the bevel 73 allows the button 42 to be
inserted into the lock 30 without manually resiliently deflecting
the locking tab, and wherein a predetermined rotation allows the
button 42 to be removed from the lock 32 easily because the button
42 facilitates deflection of the tab. This feature is highly
desirable for individuals who have difficulty using their hands,
wherein use of the resiliently deflectable tab may be difficult.
Further, individuals, such as the elderly or the disabled, will be
able to easily utilize this embodiment of the present invention
since the unlocking mechanism simply entails selective rotation of
the electronic device.
[0126] Generally, the button 42 is constructed with a predetermined
thickness. In order to create the bevel 73, the thickness of the
button 42 is selectively trimmed at a predetermined angle relative
to the top of the button 42. This cut defines a bevel portion 73 on
the button 42 which allows for substantially unobstructed travel of
the button 42 in and out of the lock. More specifically, the button
42 is defined after the bevel 73 of angle .theta. is created by an
unaffected portion of length d. The angle .theta. and the length d
may be of any dimension depending on the thickness of the button 42
and the locking requirements required. Preferably, in one
embodiment of the invention, d is about 3/8 inches. In addition,
the beveled portion 73 may span any distance around a perimeter of
the circular button 42 as long as sufficient non-beveled area
remains to ensure that locking is possible, wherein more than small
rotations of the electronic device will facilitate unlocking. For
example, in one embodiment of the invention the bevel spans at
least about 50%, or about 180.degree., around the perimeter of the
button 42. Further, the bevel 73 may be made of one smooth swept
cut around the perimeter, or may be made of a series of faceted
cuts to allow for various locking and unlocking options. In one
embodiment of the present invention, the angle .theta. is about
30.degree..
[0127] Referring now to FIGS. 33-37, an alternate embodiment of the
present invention is shown that provides greater locking
capabilities. More specifically, one embodiment of the present
invention, similar to that described above, includes a locking
relief 80 integrated into the button 42 and a locking cavity 82
integrated into the tab 15 of the lock portion 30. As described
above, the bevel 73 is designed to either pass completely over the
locking lip 16 of the tab 15 or alternatively to facilitate
deflection of the tab 15 by a sliding engagement between the
beveled area 72 and the locking lip 16, thereby allowing the button
42 to be seated into the locking pocket 19. In addition, this
embodiment of the present invention includes the locking cavity 82
that is generally an annulus removed from the locking lip 16 of the
tab. As shown herein, a triangular annulus angle .phi. is shown
that spans the length of the locking lip 16. However, one skilled
in the art will appreciate that any shape and length of the locking
cavity 16 maybe employed without departing from the scope of the
invention. In combination with the locking cavity 82, a locking
relief 80 is provided on the underside of the button 42 that is
opposite from the beveled side, as shown most distinctly in FIG.
37. This locking relief, as shown herein, is generally a triangular
bevel of angle .gamma. is designed to selectively engage the
locking cavity 82 of the tab 15.
[0128] One skilled in the art will appreciate that the length of
the locking relief 86 may be any practical value as long as it
selectively locks into the locking cavity 82 of the tab 15. More
specifically, the length of the locking relief 80 of the button 42
maybe such that only one locking position may be provided, wherein
a small locking cavity, or groove, receives a small locking relief
80, for example. This embodiment of the present invention provides
the user with a more enhanced locking feature such that normal wear
and tear of the surfaces on the locking lip 16 and the interface
surface of the button 42 will not substantially affect the locking
of the button in the locking portion 30 of the clip. More
specifically, the engagement of the button in the cavity
substantially prevents the electronic device from being slipped out
of the locking cavity and/or pulled therefrom.
[0129] Referring now specifically to FIGS. 33 and 35, a locking
mechanism that utilizes a locking relief 80 and locking cavity 82
is shown. A protuberance of any shape may be employed with a
aperture 86 integrated therethrough to provide locations for the
interconnection of belts, straps, strings, ropes, etc. In addition,
the locking portion of the clip 30 maybe provided with a section
for the placement of an aperture 86 for the interconnection of
similar devices, such that the separable locking mechanism may be
used in a number of applications. For example, the present
invention may be employed as a belt buckle, clasp, or any other
similar type mechanism that is easy to use, which would aid elderly
or disabled individuals.
[0130] Referring now to FIG. 3-7, a method of engagement of one
embodiment of the present invention that includes a locking cavity
82 and locking relief 80 is described. More specifically, one
embodiment of the present invention is slid into the locking
portion 30 of the clip wherein the beveled area 73 either passes by
the locking lip 16 or facilitates deflection of the locking tab 15
by engagement therewith. Once the button 42 is seated in the
locking pocket 19, the device is substantially constrained from
disengagement. If upward motion, as shown in the figure motion to
the left, is attempted, the locking relief 80 and the locking
cavity 82 will become engaged such that upward motion is
substantially prevented.
[0131] While various embodiments of the present invention have been
described in detail, it is apparent that modifications and
adaptations of those embodiments will occur to those skilled in the
art. However, it is to be expressly understood that such
modifications and adaptations are within the spirit and scope of
the present invention, as set forth in the claims that follow.
