SUMMARY OF INVENTION
It is therefore a primary objective of the claimed invention to
provide an electronic accessory capable of securely attaching to
a mobile phone.
According to the claimed invention, the mobile phone has a first
slot located on a bottom side of the mobile phone and a pair of
second slots respectively located on two sides of the mobile phone.
The electronic accessory comprises a housing, a pair of first hooks,
and a pair of second hooks.
The pair of first hooks is installed inside the housing for attaching
the electronic accessory to the mobile phone. Each first hook comprises
an inlaying end and an imposing end. When the electronic accessory
is attached to the mobile phone, the pair of inlaying ends of the
pair of first hooks is respectively inlayed into two sides of the
first slot of the mobile phone. When forces toward an inner side
of the housing are imposed on the pair of imposing ends, the pair
of imposing ends and the pair of inlaying ends synchronically move
toward the inner side of the housing. When the pair of imposing
ends move toward the inner side of the housing by a predetermined
distance due to the forces imposed on the pair of imposing ends,
the pair of inlaying ends and the pair of imposing ends synchronically
move toward the inner side of the housing such that the electronic
accessory can be detached from the mobile phone.
The pair of second hooks is installed inside the housing for attaching
the electronic accessory to the mobile phone. Each second hook comprises
an inlaying end, an imposing end, and a pivot located between the
inlaying end and the imposing end and rotatably fastened to the
housing. When the pair of inlaying ends of the pair of first hooks
of the electronic accessory is inlayed into the two sides of the
first slot of the mobile phone, the pair of inlaying ends of the
pair of second hooks of the electronic accessory is synchronically
inlayed into the pair of second slots of the mobile phone. When
the pair of imposing ends of the pair of second hooks of the electronic
accessory is imposed upon by two forces to move toward the inner
side of the housing by the predetermined distance, the pair of inlaying
ends of the second hooks of the electronic accessory synchronically
move toward a direction opposite from the inner side of the housing
by the determined distance to synchronically detach the pair of
inlaying ends of the second hooks from the pair of second slots
and the pair of inlaying ends of the pair of first hooks from the
first slot of the mobile phone.
It is an advantage of the claimed invention that the electronic
accessory uses two pairs of hooks, not just one pair of hooks, to
attach more securely to the mobile phone.
These and other objectives of the claimed invention will no doubt
become obvious to those of ordinary skill in the art after reading
the following detailed description of the preferred embodiment that
is illustrated in the various figures and drawings.
BRIEF DESCRIPTION OF DRAWINGS
FIG. 1 is a schematic diagram showing a prior art electronic accessory
attached to a mobile phone.
FIG. 2 is a schematic diagram showing an electronic accessory attached
to a mobile phone according to the present invention.
DETAILED DESCRIPTION
Please refer to FIG. 2, which shows an electronic accessory 40
attached to a mobile phone 30 according to the present invention.
The mobile phone 30 comprises a first slot 32 located on a bottom
side of the mobile phone 30, a pair of second slots 34 respectively
located on two sides of the mobile phone 30, and a plurality of
holes 36. The electronic accessory 40 comprises a housing 42 (shown
as hashed lines in FIG. 2), a pair of first hooks 44 installed inside
the housing 42 for attaching the electronic accessory 40 to the
mobile phone 30, a pair of second hooks 46 installed inside the
housing 42 for attaching the electronic accessory 40 to the mobile
phone 30, a pair of elastic materials 48, such as springs, a pair
of control poles 50, a plurality of pins 52 corresponding to the
plurality of holes 36 of the electronic accessory 40, and related
circuits 80. When the electronic accessory 40 is attached to the
mobile phone 30, the pins 52 and the corresponding holes 36 are
mated and serve as data channels between the electronic accessory
40 and the mobile phone 30. The related circuits 80 of the electronic
accessory 40 are related to the functionality of the electronic
accessory 40. For example, if the electronic accessory 40 is a charger,
the related circuits 80 comprise transformers, and if the electronic
accessory 40 is a keypad, the related circuits 80 comprise input/output
circuits.
Because the attaching-related devices of the electronic accessory
40 for attaching the electronic accessory 40 to the mobile phone
30, such as the first hooks 44 and control poles 50 etc, are all
located symmetrical to a center line C-C" of the electronic
accessory 40, only the attaching-related devices located on the
left-hand side of the center line C-C" are described in following
paragraphs. Configurations and operations of the attaching-related
devices located on the right-hand side of the center line C-C"
are identical to those of the attaching-related devices located
on the left-hand side of the center line C-C". Moreover, when
the electronic accessory 40 is attached to the mobile phone 30,
the plurality of pins 52 of the electronic accessory 40 are inserted
into the plurality of holes 36 of the mobile phone 30 in a one-to-one
correspondence. When the electronic accessory 40 is detached from
the mobile phone 30, the pins 52 are also, of course, detached from
the holes 36.
The first hook 44 of the electronic accessory 40 comprises an inlaying
end 54 and an imposing end 56. The inlaying end 54, shown in FIG.
2, of the first hook 54 is arrow-shaped to guarantee that the inlaying
end 54 of the first hook 44 will not separate from the first slot
32 of the mobile phone 30 after the inlaying end 54 has been inlayed
into the first slot 32 of the mobile 30 and the electronic accessory
40 has been attached to the mobile phone 30. When the electronic
accessory 40 is attached to the mobile phone 30, the inlaying end
54 of the first hook 44 of the electronic accessory 40 is inlayed
into the first slot 32 of the mobile phone 30. When the imposing
end 56 of the first hook 44 is applied by a force toward the inner
side (in the direction indicated by an arrow 90) of the housing
42 of the electronic accessory 40, the inlaying end 54 synchronically
moves toward the inner side of the housing 42. When the imposing
end 56 has moved toward the inner side of the housing 42 by a predetermined
distance due to the force, the inlaying end 54 of the first hook
44 synchronically moves along with the imposing end 56 toward the
inner side of the housing 42 and thus the electronic accessory 40
can be detached from the mobile phone 30. In the preferred embodiment
of the present invention, the electronic accessory 40 is a charger
and the predetermined distance is approximately 0.6 mm.
The second hook 46 of the electronic accessory 40 comprises an
inlaying end 58, an imposing end 60, and a pivot 62 rotatably fixed
to the housing 42 and located between the inlaying end 58 and the
imposing end 60. When the inlaying end 54 of the first hook 44 of
the electronic accessory 40 is inlayed into the first slot 32 of
the mobile phone 30, the inlaying end 58 of the second hook 46 of
the electronic accessory 40 is synchronically inlayed into the second
slot 34 (located on the left-hand side of the center line C--C)
of the mobile phone 30. When the imposing end 60 of the second hook
46 of the electronic accessory 40 is imposed by a force to move
toward the inner side of the housing 42 by the predetermined distance,
the imposing end 60, having moved toward the inner side of the housing
42 by the predetermined distance, synchronically drives the control
pole 50 to move toward the inner side of the housing 42 by the predetermined
distance. Similarly, the driven control pole 50 also drives the
imposing end 56 of the first hook 44 to move toward the inner side
of the housing 42 by the predetermined distance (why the control
pole 50 moves along with the movement of the imposing end 60 of
the second hook 46 will be explained in the following paragraph).
The inlaying end 58 of the second hook 46 of the electronic accessory
40 moves synchronically toward the direction opposite from the inner
side of the housing 42 due to the lever principle to detach from
the second slot 34 of the mobile phone 30. That is, the inlaying
end 58 of the second hook 46 and the inlaying end 54 of the first
hook 44 are synchronically respectively detached from the second
slot 34 and the first slot 32 of the mobile phone 30.
The control pole 50 of the electronic accessory 40 comprises a
first end 64 contacted to the imposing end 60 of the second hook
46 of the electronic accessory 40, and a second end 66 contacted
to the imposing end 56 of the first hook 44 of the electronic accessory
40. When the first end 64 of the control pole 50 is applied a force
to move toward the inner side of the housing 42 by the predetermined
distance, the imposing end 60 of the second hook 46 is driven toward
the inner side of the housing 42 by the predetermined distance causing
the second hook 46 to rotate around the pivot 62, detaching the
inlaying end 58 of the second hook 46 from the second slot 34. Simultaneously,
the movement of the second end 66 of the control pole 50 drives
the imposing end 56 of the first hook 44 of the electronic accessory
40 to move toward the inner side of the housing 42 by the predetermined
distance, detaching the inlaying end 54 from the first slot 32.
The elastic material 48 (a spring) of the electronic accessory
40 is mounted onto the control pole 50. One end of the elastic material
48 is located against the contact pole 50 at node D, shown in FIG.
2, while the other end of the elastic material 48 is located against
to the housing 42 at node E. When the imposing end 56 of the second
hook 46 of the electronic accessory 40 is imposed upon by a force
to move toward the inner side of the housing 42 by the predetermined
distance, the elastic material 48 is synchronically compressed by
the control pole 50. When the imposing end 56 of the second hook
46 of the electronic accessory 40 is freed from the force, the elastic
material 48 rebounds the control pole 50 toward the opposite direction
from the inner side of the housing 42 by the predetermined distance.
Please note that the first hook 44 is made of a kind of elastic
materials. That is, when a force is applied to the imposing end
56 of the first hook 44, the inlaying end 54 of the first hook 44
of the electronic accessory 40 synchronically moves toward the inner
side of the housing 42 by the predetermined distance. If the force
is not applied to the imposing end 56 of the first hook 44, the
inlaying end 54 of the first hook 44 will rebound toward the direction
opposite from the inner side of the housing 42 by the predetermined
distance.
In contrast to the prior art electronic accessory 10 having only
one pair of hooks, the present invention electronic accessory 40
comprises not only a pair of first hooks 44 but a pair of second
hooks 46, so the electronic accessory 40 can attach to the mobile
phone 30 more securely than can the prior art electronic accessory
10. Additionally, the lever principle is employed for the attachment/detachment
of the electronic accessory 40 and the mobile phone 30. When the
imposing end 60 of the second hook 46 of the electronic accessory
40 receives a force, the imposing end 60 of the second hook 46 and
the imposing end 56 of the first hook 44 synchronically move toward
the inner side of the housing 42 by the predetermined distance,
and the inlaying end 58 of the second hook 46 and the inlaying end
54 of the first hook 44 synchronically move in two opposite directions
such that the electronic accessory 40 can detach from the mobile
phone 30. Such a design of the pairs of hooks of the electronic
accessory 40 makes the electronic accessory 40 be capable of securely
attaching to the mobile phone 30.
Following the detailed description of the present invention above,
those skilled in the art will readily observe that numerous modifications
and alterations of the device may be made while retaining the teachings
of the invention. Accordingly, the above disclosure should be construed
as limited only by the metes and bounds of the appended claims. |
