Abstract
A car phone holder has a base for holding a car phone, a first suspension rod rotatably connected to a back of the base, a second suspension rod pivotally connected with the first suspension rod and a universal joint provided between the back of the base and a distal end of the first suspension rod. The universal joint allows the base to rotate in any desired direction and the pivotal engagement between the first and second suspension rods allows the base to orient in a direction required.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a car phone holder, and more particularly to a car phone holder with a universal joint with which the car phone supported by the holder is able to pivot to any desired direction to facilitate the access for the user.
2. Description of Related Art
A conventional car phone holder, as shown in
FIG. 1
, has a base (
1
a
) and an electrical suspension rod (
2
a
) that is electrically connected to a cigarette lighter (not shown) for provide electricity to the base (
1
a
). The base (
1
a
) has a stub (
1
a
) formed on a back of the base (
11
a
) to correspond to a clamp (
3
a
) formed on one end of the electrical suspension rod (
2
a
). The clamp (
3
a
) is composed of two extensions (
31
a
) extending out in parallel from the end of the electrical suspension rod (
2
a
), such that the stub (
11
a
) is able to be pivotally secured between the two extensions (
31
a
) by means of a screw (
4
a
). With such an arrangement, the phone holder is able to pivot in relation to the end of the electrical suspension rod (
2
a
) and the user is able to adjust the angle of the phone holder as required.
However, the phone holder can only pivot with respect to the electrical suspension rod (
2
a
), that is, the phone holder can not be adjusted transversely to fulfill the user's need, not to mention the electrical outlet for the electrical suspension rod (
2
a
) normally is located under the front panel of the car, which hinders the access of the user to the gear shift and thus affects the driving safety greatly.
To overcome the shortcomings, the present invention intends to provide an improved car phone holder to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
The primary objective of the invention is to provide a car phone holder enabling to pivot in all directions to facilitate the access by the user. The car phone holder includes a base, a first extension rod connected to the base and a second extension rod pivotally connected to a free end of the first extension rod. The connection between the base and the first extension rod enables the base to pivot in all directions and the connection between the first and the second extensions enables the first extension rod to pivot up and down, such that the user is able to adjust the base to any desired direction as required.
Another objective of the invention is to have an electrical outlet mounted on a mediate portion of the second extension rod, such that the user is still able to use the outlet as a cigarette lighter without worrying that the original cigarette lighter is being occupied.
Still another objective of the invention is to have the electrical wire from the base to the first extension rod detachable, such that the user is able to disassemble the base from the car phone holder and relocate it with an indoor outlet to function as a rechargeable seat for a mobile phone.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
With reference to
FIGS. 2 and 3
, a car phone holder in accordance with the present invention has a base (
1
) for detachably receiving a car phone, a first suspension rod (
2
) and a second suspension rod (
3
).
A universal joint (
4
) is provided to pivotally engage a back of the base (
1
) to a first distal end of the first suspension rod (
2
). The universal joint (
4
) has a bowl (
41
) extending from the back of the base (
1
), two complementarily formed arcuate plates (
42
) respectively formed on a first distal end of a first and a second halves (
21
,
22
) of the first suspension rod (
2
), threads (
43
) formed on an outer peripheries of the first and the second halves (
21
,
22
) to form an annular thread around a joint between the two arcuate plates (
42
) and the two halves (
21
,
22
) and an annular sleeve (
5
) slidably engaged with the first suspension rod (
2
) and having inner threads (
51
) formed on an inner face of the annular sleeve (
5
) to correspond to the threads (
43
). Two clamping plates (
23
) are respectively formed on a second distal end of the first and the second halves (
21
,
22
) and each of the clamping plates (
23
) defines therethrough a through hole (
231
).
A first distal end of the second suspension rod (
3
). has spatially apart two plates (
32
) each with a hole (
321
) defined to align with the through holes (
231
) of the two clamping plates (
23
). A second distal end of the suspension rod (
3
) is provided with an electrical connection (
31
) adapted to connect with the cigarette lighter for providing electricity to the car phone holder of the present invention. Furthermore, an extra electrical outlet (
7
) is formed on a mediate portion of the second suspension rod (
3
), such that even the original electrical outlet on the car is occupied by the car phone holder of the invention, the extra electrical outlet (
7
) still provides the user an alternate choice for other car appliances.
When the car phone holder of the invention is in assembly, the bowl (
41
) is received in a space defined by the two complementary arcuate plates (
42
) and then the sleeve (
5
) slides through the first suspension rod (
1
) to threadingly mate with the threads (
43
) as well as to secure the first and second halves (
21
,
22
), which also secures the bowl (
41
) inside the two arcuate plates (
42
), as shown in FIG.
4
. Thereafter the two clamping plates (
23
) insert between the two plates (
32
) of the second suspension rod (
3
) to align the through holes (
231
) with the holes (
321
) of the plates (
32
). Then, a screw (
6
) extends through the aligned through holes (
231
) and holes (
321
) to engage with a nut (
61
) to secure the engagement between the first and the second suspension rods (
2
,
3
).
Because the bowl (
41
) is received in the space defined by the two complementarily formed arcuate plates (
42
), the bowl (
41
) is able to rotate to any direction as required and also because the two clamping plates (
23
) are received between the two plates (
32
), the second distal end of the first suspension rod (
2
) is pivotal with respect to a first distal end of the second suspension rod (
3
). With such an arrangement, the base (
1
) together with the first suspension rod (
2
) enables the user to pivot the car phone holder to any desired angle and direction, as shown in FIG.
5
.
With reference to
FIGS. 6
to
9
, in order to facilitate the use of the car phone holder of the present invention, the base (
1
) has a key hole (
11
) with two oppositely defined notches (
111
,
112
) and the firs suspension rod (
2
) has a key (
411
) formed to correspond to the key hole (
11
) and having two oppositely formed ears (
412
,
413
) corresponding to the notches (
111
,
112
) respectively, such that when the base (
1
) and the first suspension rod (
2
) are assembled, correct polarity is ensured. However, to further ensure the polarity between the base (
1
) and the first suspension rod (
2
), the first suspension rod (
2
) further has a rib (
414
) formed between the distal end of the first suspension rod (
2
) and the universal joint (
4
) and a slit (
113
) is defined in a face defining the key hole (
1
1
) of the base (
1
) so that after the key (
411
) is received in the key hole (
11
) and rotated for
90
degree, the rib (
414
) is received in the slit (
113
) in the key hole (
11
).
