Mobile Phone Patent Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a mobile phone charger, and more
particularly to a rotatable charger adapted for connection with
an onboard power source.
2. Description of Related Art
Mobile phone chargers are usually classified into two different
categories, one has a seat for receiving therein the mobile phone
and the other one has only a cable with a transformer therein. Depending
on the situation available, the mobile phone users will choose the
best category to charge the mobile phones. In order to facilitate
the charging process for those who are onboard a vehicle, such as
a car, a charger adapted for use with an onboard cigarette lighter
socket is provided. The mobile phone users are able to place the
mobile phones on the chargers which are connected to the onboard
cigarette lighter socket to recharge the mobile phone. However,
after the mobile phone is placed on the charger, the mobile phone
is substantially fixed, which often hinders the driver's movement
and sometimes even causes an accident if the driver's movement is
interrupted.
To overcome the shortcomings, the present invention tends to provide
an improved mobile phone charger to mitigate the aforementioned
problems.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide an
improved mobile phone charger adapted for connection with an onboard
cigarette lighter socket and having a connector for connection with
the cigarette lighter socket and a body pivotally connected to the
connector so that after the mobile phone is placed on top of the
body, the mobile phone is moved along with the body to best fit
the driver's position.
Another objective of the present invention is to provide a holder
detachably and rotatably mounted on top of the body to clamp a mobile
phone to facilitate access of the mobile phone.
Other objects, advantages and novel features of the invention will

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to FIG. 1, the mobile phone charger constructed
in accordance with the present invention includes a connector (1)
adapted for connection with an onboard cigarette lighter socket
and a body (2).
The connector (1) has a connection tip (11) extending from a first
distal end of the connector (1) for connection with the cigarette
lighter socket, multiple adjusting holes (12) defined in a second
distal end opposite to the first distal end of the connector (1),
and a rotation column (13) formed close to and extending from opposite
sides of the second distal end of the connector (1).
The body (2) is substantially hollow and composed of a top cover
(21), a bottom cover (22) and two side covers (24) oppositely sandwiched
between the top cover (21) and the bottom cover (22). The top cover
(21) has two arcuate cutouts (20) respectively defined in two opposite
side faces of the top cover (21) to respectively mate a peripheral
configuration of the side covers (24), and two first recesses (210)
defined in a front portion of the body (2) to correspond to the
rotation column (13) of the connector (1). One of the side covers
(24) has a recessed area (241) defined in an inner face of the side
cover (24) and a bottom face defining the recessed area (241) is
made of a resilient material such that the bottom face of the side
cover (24) is able to move relative to the other side cover (24).
A boss (23) integrally formed on a seat (230) and corresponding
to the adjusting holes (12) of the connector (1) is formed on a
front end of the body (2). The seat (230) is integrally formed with
the front end of the body (2) with the boss (23) extending out of
a side face of the seat (230). A driving rod (25) is provided between
the two side covers (24) and has a concave portion (251) and a convex
portion (252) both formed on a side face of the driving rod (25)
and adjacent to each other. A spring (26) is provided between a
distal end of the driving rod (25) and a bottom face of the side
cover (24). The bottom cover (22) has two second recesses (220)
formed to correspond to the first recesses (210) of the top cover
(21) and the rotation column (13) of the connector (1).
With reference to FIG. 2, the top cover (21) further has a keyhole
shaped opening (211) with a lip (212) formed on a periphery of the
opening (211). A substantially L-shaped spring board (213) has a
first end securely attached to a bottom face of the top cover (21),
a first boss (2131) and a second boss (2132) both formed on a top
face of the spring board (213) and exposed to the opening (211).
The first boss (2131) has a dimension larger than a dimension of
the second boss (2132). A cover (214) is configured to have a dimension
slightly smaller than that of the opening (211) so that the cover
(214) is able to be snugly received in the opening (211). The cover
(214) has a tongue (2141) formed on an end of the cover (214) to
correspond to the lip (212) in the opening (211). Therefore, when
the cover (214) covers the opening (211), the tongue (2141) engaging
the lip (211) secures the combination between the cover (214) and
the top cover (21).
A power wire (3) is electrically connected to the connector (1)
by any appropriate method. Because the connection between the power
wire (3) and the connector (1) is conventional in the art, detailed
description thereof is thus omitted.
With reference to FIGS. 3, 3A and 3B, after the connector (1) and
the body (2) are connected to each other, it is noted that the first
recesses (210) and the second recesses (220) encase the rotation
column (13) of the connector (1) such that the body (2) is able
to pivot relative to the connector (1) or vice versa. Furthermore,
after the combination between the connector (1) and the body (2)
is completed, one end of the driving rod (25) abuts the bottom face
defining the recessed area (241) and the other end of the driving
rod (25) abuts one distal end of the spring (26) the other end of
which abuts a side face of the other side cover (24). In the meantime,
the protruded area (252) engages the seat (230) to force the boss
(23) to extend out of the body (2) and into one of the adjusting
holes (12) thereby securing the pivotal relationship between the
connector (1) and the body (2). However, when the bottom face defining
the recessed area (241) of the side cover (24) is pressed to cause
the driving rod (25) to move relative to the spring (26), the seat
(230) aligns with the concave portion (251). Because the abutting
force to the seat (230) is temporarily removed, the seat (230) along
with the boss (23) springs back into the body (2) to allow the body
(2) to pivot relative to the connector (1). Further, because the
connector (1) normally is inserted into the onboard cigarette lighter
socket, the connector (1) is securely fixed. Therefore, the user
is able to pivot the body (2) relative to the connector (1) to adjust
the body (2) to a position adapted to the user's position. After
the body (2) is adjusted by pivoting the body (2) relative to the
connector (1), the user removes the pressing force to the side face
of the side cover (24) and thereby the recoil force of the spring
(26) forces the driving rod (25) to move to the side cover (24)
to resume the original position of the driving rod (25), which allows
the protruded area (252) to abut the seat (230) again. After the
seat (230) is abutted by the protruded area (252), the boss (23)
is again forced to extend out of the body (2) and into one of the
adjusting holes (12) to once again secure the position between the
connector (1) and the body (2), as shown in FIG. 4.
With reference to FIG. 5, a rotation clamp (4) adapted for clamping
a mobile phone (not shown) is provided to have a flange (42) connected
to a bottom face of the rotation clamp (4) by a neck (43) and having
a first concavity (421) defined in a bottom face of the flange (42)
to correspond to the first boss (2131) and second concavities (422)
also defined in the bottom face of the flange (42) to correspond
to the second boss (2132). The first concavity (421) has a dimension
slightly larger than that of the first boss (2131) and each second
concavity (422) has a dimension slightly larger than that of the
second boss (2132) so that the first boss (2131) is able to be received
in the corresponding first concavity (421) and the second boss (2132)
is able to be received in any one of the corresponding second concavities
(422).
When the rotation clamp (4) is to be used with the body (2), the
side cover (24) is removed to expose the opening (211). Then the
flange (42) is inserted into the opening (211) to allow a peripheral
edge to abut a peripheral edge of the opening (211). Meanwhile,
the first and second bosses (2131,2132) are respectively received
in the first concavity (421) and one of the second concavities (422).
Thus, the user is able to use the combination of the connector (1)
and the body (2) to hold the mobile phone with the rotation clamp
(4) rotatably mounted on top of the body (2). It is to be noted
that when the rotation clamp (4) is rotated relative to the body
(2), the second boss (2132) sliding through one of the second concavities
(422) provides a temporary positioning effect to the rotation clamp
(4).
Therefore, not only can the mobile phone be rotated in a latitudinal
direction, the mobile phone can also be rotated in a longitudinal
direction relative to the connector (1).
It is to be understood, however, that even though numerous characteristics
and advantages of the present invention have been set forth in the
foregoing description, together with details of the structure and
function of the invention, the disclosure is illustrative only,
and changes may be made in detail, especially in matters of shape,
size, and arrangement of parts within the principles of the invention
to the full extent indicated by the broad general meaning of the
terms in which the appended claims are expressed.
