Description
FIELD OF THE INVENTION
[0001] The present invention relates to a protective case, and more
particularly to a protective case with a fixing strap.
BACKGROUND OF THE INVENTION
[0002] Generally, portable electronic devices such as mobile phones
or tablet computers are not equipped with keyboards. Consequently,
the size and weight of the portable electronic device can meet the
requirement of most users. That is, the portable electronic devices
can be carried and used more easily. During the commute time or in
many different circumstances, the users can operate the portable
electronic devices. For holding and operating the portable
electronic device simultaneously, the user usually holds the
portable electronic device with one hand and operates the portable
electronic device with the other hand. Since the portable
electronic device is held with the single hand, the portable
electronic device possibly falls down from the hand. Since the
portable electronic device is knocked or collided by the floor, the
possibility of causing damage or breakdown of the portable
electronic device increases. Therefore, the manufacturers make
efforts in providing a portable electronic device that can be
simultaneously held and operated by the user in a convenient
manner.
[0003] In accordance with a widely-used approach, a protective case
of the portable electronic device is equipped with a fixing strap
for holding the hand of the user. By means of the fixing strap, the
possibility of falling down the portable electronic device will be
minimized. Some conventional technologies using the fixing strap
will be illustrated as follows.
[0004] For example, Taiwanese Patent No. 1439217 discloses a
portable electronic device with a fixing strap. In Taiwanese Patent
No. 1439217, two ends of the fixing strap are connected with two
positions of a circular rotatory disc having a central hollow
portion. The rotatory disc is installed on a backside surface of a
tablet computer. After a hand of the user is inserted into the
space under the fixing strap and the hand is held between the
backside surface of the tablet computer and the fixing strap, the
tablet computer will not be detached from the hand of the user.
However, since the rotatory disc and the fixing strap are protruded
from a surface of the tablet computer, the tablet computer is not
aesthetically pleasing and the tablet computer is stored with
difficulty.
[0005] Furthermore, U.S. Pat. No. 8,550,317 also discloses a
protective case with a fixing strap. In U.S. Pat. No. 8,550,317,
the protective case has a circular opening. The two ends of the
fixing strap are accommodated within the protective case. A middle
segment of the fixing strap is penetrated through the circular
opening so as to be pulled in the direction away from the
protective case. However, since the length of the fixing strap
pulled out from the circular opening is constant, the fixing strap
is too short or too long for different users. That is, the fixing
strap cannot be used for various sizes of hands. Moreover, since
the fixing strap cannot be automatically retracted back when the
fixing strap is not used, the fixing strap is not
user-friendly.
[0006] Furthermore, US Patent Publication No. 20110309117 discloses
a protective case of a portable electronic device with a fixing
strap. In US Patent Publication No. 20110309117, the two ends of
the fixing strap are inserted into the protective case, and a
portion of the fixing strap is exposed outside the protective case.
Moreover, a tail end of the fixing strap comprises plural ridges,
and plural grooves are formed in an inner surface of the protective
case. When the portion of the fixing strap exposed outside the
protective case is pulled, the engagement through the plural ridges
and the corresponding grooves can achieve the positioning purpose.
Consequently, the length of the portion of the fixing strap exposed
outside the protective case is adjustable. That is, the length of
the portion of the fixing strap exposed outside the protective case
can be adjusted through the plural ridges and the plural grooves.
However, since the numbers and positions of the plural ridges and
the plural grooves are fixed, the fixing strap cannot be used for
various sizes of hands. Similarly, the fixing strap cannot be
automatically retracted back when the fixing strap is not used.
[0007] From the above discussions, the conventional fixing strap
adversely affects the aesthetically-pleasing efficacy of the
portable electronic device and the protective case and is not
suitably used for various sizes of hands.
[0008] Therefore, there is a need of providing an improved
protective case with a fixing strap in order to overcome the above
drawbacks.

[0035] As shown in FIGS. 5 and 6, the fixing strap 11 comprises a
first elastic part 111, a second elastic part 112 and a connecting
part 113. The first elastic part 111 comprises plural openings 114.
The second elastic part 112 comprises plural openings 115. By means
of the plural openings 114 and the plural openings 115, the elastic
forces of the first elastic part 111 and the second elastic part
112 are adjustable. It is noted that the numbers and shapes of the
plural openings 114 and the plural openings 115 are not restricted.
That is, the numbers and shapes of the plural openings 114 and the
plural openings 115 may be varied according to the required elastic
forces of the first elastic part 111 and the second elastic part
112. In this embodiment, the plural openings 114 include three
oblong openings, and the plural openings 115 also include three
oblong openings. According to the practical requirements, the
shapes of the openings may be changed (e.g., circular openings).
Regardless of how the shapes of the openings are changed, the
number and shape of the plural openings 114 are identical to the
number and shape of the plural openings 115. Consequently, the
elastic forces of the first elastic part 111 and the second elastic
part 112 are identical. More preferably, the connecting part 113 is
made of a non-elastic material. Preferably but not exclusively, the
first elastic part 111 and the second elastic part 112 are made of
silicon resin.
[0036] The connecting part 113 comprises two first connecting
grooves 116, 1161 and two second connecting grooves 117, 1171. The
first connecting grooves 116 and 1161 are located at a first end of
the connecting part 113. The second connecting grooves 117 and 1171
are located at a second end of the connecting part 113. The first
elastic part 111 comprises two first connecting blocks 118, 1181
and two first bulges 119, 1191. The first connecting blocks 118 and
1181 are located at a first end of the elastic part 111. The first
bulges 119 and 1191 are located at a second end of the elastic part
111. The second elastic part 112 comprises two second connecting
blocks 120, 1201 and two second bulges 121, 1211. The second
connecting blocks 120 and 1201 are located at a first end of the
second elastic part 112. The second bulges 121 and 1211 are located
at a second end of the second elastic part 112. The first
connecting blocks 118 and 1181 are locked into the corresponding
first connecting grooves 116 and 1161. The second connecting blocks
120 and 1201 are locked into the corresponding second connecting
grooves 117 and 1171. Consequently, the first elastic part 111 and
the second elastic part 112 are respectively connected with the
first end and the second end of the connecting part 113.
[0037] In an embodiment, the first connecting grooves 116, 1161 and
the second connecting grooves 117, 1171 are integrally formed with
the connecting part 113. In another embodiment, the first
connecting grooves 116, 1161 and the second connecting grooves 117,
1171 are individual components that can be easily replaced by the
user. In an embodiment, the first connecting blocks 118, 1181 and
the first bulges 119, 1191 are integrally formed with the first
elastic part 111. In another embodiment, the first connecting
blocks 118, 1181 and the first bulges 119, 1191 are individual
components. In an embodiment, the second connecting blocks 120,
1201 and the second bulges 121, 1211 are integrally formed with the
second elastic part 112. In another embodiment, the second
connecting blocks 120, 1201 and the second bulges 121, 1211 are
individual components.
[0038] In the above embodiment, the fixing strap 11 comprises two
first connecting grooves, two second connecting grooves, two first
connecting blocks and two second connecting blocks. It is noted
that the numbers of the connecting grooves and the connecting
blocks are not restricted to those shown in the drawings. For
example, in another embodiment, a single connecting groove is
connected with a single connecting block or plural connecting
blocks. Alternatively, in a further embodiment, each elastic part
has a single connecting block.
[0039] Hereinafter, the sequence of assembling the main body 10 and
the fixing strap 11 will be illustrated with reference to FIGS. 2,
3, 4, 7, 8 and 9. FIG. 7 is a schematic perspective view
illustrating the combination of the main body and the fixing strap
of the protective case according to the embodiment of the present
invention, which is taken along an inside viewpoint. FIG. 8 is a
schematic perspective view illustrating the combination of the main
body and the fixing strap of the protective case according to the
embodiment of the present invention, which is taken along an
outside viewpoint. FIG. 9 is a schematic perspective view
illustrating the protective case according to the embodiment of the
present invention in a usage status.
[0040] As mentioned above, the main body 10 further comprises the
hollow portion 106. In the assembling process, the connecting part
113 is disposed within the hollow portion 106, and the connecting
part 113 is contacted with the stopping plate 107 so as to be
positioned. Moreover, after the connecting part 113 is embedded
within the hollow portion 106, the connecting part 113 is
substantially coplanar with an outer surface 109 of the main body
10 (see FIG. 8).
[0041] The first elastic part 111 and the second elastic part 112
are introduced into the main body 10 through the two connection
holes 108 at the two opposite sides of the stopping plate 107.
Moreover, the first bulges 119 and 1191 of the first elastic part
111 are respectively locked into the first locking slots 103 and
1031 at the first lateral side 102 of the inner surface 101 of the
main body 10. The second bulges 121 and 1211 of the second elastic
part 112 are respectively locked into the second locking slots 105
and 1051 at the second lateral side 104 of the inner surface 101 of
the main body 10. Consequently, the first elastic part 111 and the
second elastic part 112 are fixed and connected to the first
lateral side 102 and the second lateral side 104 of the inner
surface 101 of the main body 10, respectively.
[0042] In the above embodiment, the main body 10 comprises two
first locking slots and two second locking slots, and the fixing
strap 11 comprises two first bulges and two second bulges. It is
noted that the numbers of the locking slots and the bulges are not
restricted to those shown in the drawings. For example, in another
embodiment, a single bulge or plural bulges are locked into the
corresponding locking slot. Alternatively, in a further embodiment,
each elastic part has a single bulge.
[0043] After the above steps are performed, the assembling process
is completed. In case that the user's hand H is inserted into the
space under the connecting part 113 and the connecting part 113 is
pulled in the direction away from the main body 10, the first
elastic part 111 and the second elastic part 112 are stretched by
the connecting part 113 and subjected to deformation. Consequently,
the user's hand H can be held between the connecting part 113 and
the main body 10. Moreover, in response to the elastic forces of
the first elastic part 111 and the second elastic part 112, the
lengths of the first elastic part 111 and the second elastic part
112 can be automatically adjusted. Consequently, the first elastic
part 111 and the second elastic part 112 can be stretched to the
appropriate lengths according to the size of the user's hand H.
Under this circumstance, the connecting part 113 is satisfactorily
attached on the user's hand H. In other words, the fixing strap 11
is suitably used for various sizes of hands.
[0044] In case that the user's hand H is withdrawn from the space
under the connecting part 113 and the connecting part 113 is no
longer pulled, the first elastic part 111 and the second elastic
part 112 are restored to their original shapes in response to the
elastic forces thereof. As the first elastic part 111 and the
second elastic part 112 are restored to their original shapes, the
connecting part 113 is correspondingly embedded within the hollow
portion 106 again.
[0045] It is noted that numerous modifications and alterations may
be made while retaining the teachings of the invention. For
example, in another embodiment, the two ends of the first elastic
part 111 and the two ends of the second elastic part 112 are
attached on the two ends of the connecting part 113 and the two
lateral sides of the inner surface 101 of the main body 10 via
solid or liquid adhesives. In case that the solid or liquid
adhesives are employed, it is not necessary to form the first
connecting blocks 118, 1181 and the first bulges 119, 1191 at the
two ends of the first elastic part 111, and it is not necessary to
form the second connecting blocks 120, 1201 and the second bulges
121, 1211 at the two ends of the second elastic part 112.
Similarly, under this circumstance, it is not necessary to form the
first connecting grooves 116, 1161 and the second connecting
grooves 117, 1171 at the two ends of the connecting part 113, and
it is not necessary to form the first locking slots 103, 1031 and
the second locking slots 105 and 1051 at the two lateral sides of
the inner surface 101 of the main body 10.
[0046] As mentioned above, the connecting part 113 is connected
with the first elastic part 111 and the second elastic part 112,
and the user's hand H is held between the connecting part 113 and
the main body 10. Since the lengths of the first elastic part 111
and the second elastic part 112 can be automatically adjusted in
response to the elastic forces of the first elastic part 111 and
the second elastic part 112, the connecting part 113 can be
satisfactorily attached on the user's hand and suitably used for
various sizes of hands.
[0047] Moreover, the main body 10 further comprises the hollow
portion 106, and the stopping plate 107 is disposed under the
hollow portion 106. Consequently, in case that the connecting part
113 is not pulled, the connecting part 113 is embedded within the
hollow portion 106 and not protruded over the outer surface 109 of
the main body 10. Moreover, the connecting part 113 and the main
body 10 are made of the same material or coated with the same
paint. Consequently, the connecting part 113 and the main body 10
have the consistent properties, and the aesthetically-pleasing
efficacy of the main body 10 is enhanced.
[0048] As mentioned above, the first elastic part 111 comprises the
plural openings 114, and the second elastic part 112 comprises the
plural openings 115. By means of the plural openings 114 and the
plural openings 115, the elastic forces of the first elastic part
111 and the second elastic part 112 are adjustable. Consequently,
during the process of assembling the protective case 1, it is not
necessary to change the materials or sizes of the first elastic
part 111 and the second elastic part 112 for adjusting the elastic
forces, and it is not necessary to change the main body 10 in
response to the changes of the sizes of the first elastic part 111
and the second elastic part 112. Under this circumstance, the
complexity and cost of fabricating the protective case 1 are
reduced.
[0049] From the above descriptions, the present invention provides
a protective case with a fixing strap. The protective case with the
fixing strap is aesthetically pleasing and suitably used for
various sizes of hands. Moreover, the protective case has reduced
fabricating complexity and reduced fabricating cost. Consequently,
the problems of the conventional technologies can be effectively
overcome.
[0050] While the invention has been described in terms of what is
presently considered to be the most practical and preferred
embodiments, it is to be understood that the invention needs not be
limited to the disclosed embodiments. On the contrary, it is
intended to cover various modifications and similar arrangements
included within the spirit and scope of the appended claims which
are to be accorded with the broadest interpretation so as to
encompass all such modifications and similar structures.
