Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the electrical wiring structure of a telephone whose main body and transmitter are foldable.

Conventionally, for example, a transmitter part was pivotally supported on a telephone body incorporating a handset and a dial, and by rotating the transmitter part, the transmitter part was stored in a storage recess in the telephone body. I have a flip phone. In this type of telephone, the electrical connection between the telephone body and the transmitter is generally made by providing openings in the casings of the telephone body and the transmitter, and running an electrical cord between these openings. This is done by passing. However, in such a structure, in order to prevent the above-mentioned opening from being exposed either during standby or during a call, the structure of the opening and the space between the telephone body and the transmitter section must be adjusted. The disadvantage was that the mechanical connection structure was complicated. Furthermore, mechanical stress such as twisting tends to occur in the electric cord when the transmitter unit is rotated, which is undesirable because reliability is reduced.

The present invention was developed in view of the above circumstances, and its purpose is to eliminate the need for openings for electrical wiring, reduce the mechanical force applied to the electrical cord, and provide a simple structure with high reliability. The purpose is to provide telephones.

In order to achieve the above object, the present invention mechanically connects the telephone main body and the transmitter section by first and second pivot shafts that are cantilevered shafts. At least one of the support shafts is provided with a hollow part that communicates between the shaft ends to spatially connect the inside of the casing of the telephone main body and the inside of the casing of the transmitter main body, and between the telephone main body and the transmitter part. The electrical cord for connecting the cable is inserted through the hollow part and wired.

An embodiment of the present invention will be described below with reference to the drawings. 1A and 1B are perspective views showing the external appearance of the telephone according to the same embodiment, in which 1 indicates the telephone main body and 2 indicates the transmitter section, respectively. Phone body 1
is equipped with a handset part 3 and a push-button dial 4, and a recess 5 for housing the transmitter part 2 is provided in a region adjacent to the push-button dial 4. One side of the storage recess 5 is open, and the transmitter section 2 is pivotally supported on each side adjacent to this opening by a pivot shaft to be described later. The transmitter section 2 rotates in the direction of arrow A in the figure, and is housed in the housing recess 5 as shown in FIG. 1a during standby, while protruding as shown in FIG. 1b during a call. Further, a claw 6 is provided on the side surface of the storage recess 5 opposite to the opening side.
This claw 6 is for maintaining the stored state of the transmitter section 2 by engaging with the locking section 2a of the transmitter section 2. This claw 6 also operates in conjunction with the operation of a button 6a provided on the side of the phone main body 1.
The transmitter section 2 is configured to release the stored and held state of the transmitter section 2. On the other hand, a hook button 7 is provided on the bottom surface of the storage recess 5. This hook button 7 operates when pressed by the transmitter section 2.

FIGS. 2 to 4 are cross-sectional views showing the internal structure of the telephone in a state in which the transmitter section 2 is housed. In each of the above figures, the claw 6 for holding the transmitter unit 2 in its stored state is integrally formed with its operation button 6a and lever 6b, and the telephone main body 1 is divided into two parts by a rotating shaft 12. Configuration housing 11
It is pivoted to. Further, the pawl 6 is always urged by a leaf spring 13 so as to protrude into the storage recess 5. On the other hand, the hook button 7, which is disposed such that its tip end 7a protrudes into the housing recess 5, has an intermediate portion 7b pivoted to the housing 11 of the telephone main body 1 by a rotation shaft 14. Also this hook button 7
The rear end 7c is the operating end 8a of the switch 8.
is in contact with. Thus, when the transmitter section 2 is stored in the storage recess 5, the hook button 7 presses the operating end 8a of the hook switch 8 to turn off the hook switch 8, while when the transmitter section 2 is not stored, the operating end of the hook switch 8 is pressed. 8a, the tip end 7a protrudes into the storage recess 5.

Now, the mounting structure of the transmitter section 2 is as follows. That is, a first pivot shaft 9 consisting of a cantilever shaft is protruded from one side of the storage recess 5 formed on one side of the housing 11 having a two-part structure, and a first pivot shaft 9 consisting of a cantilevered shaft is provided on one side of the housing recess 5 formed in one side of the housing 11 having a two-part structure. The first pivot shaft 9 of the housing 21 of the configuration
A hole 22 for a bearing is provided at a position corresponding to . Here, the first pivot shaft 9 is provided with a hollow portion 9a. This hollow portion 9a allows the inside of the housing 21 of the handset unit 2 and the inside of the housing 11 of the telephone main body 1 to communicate with each other when the handset unit 2 is pivotally supported. Further, a coil spring 9b is wound around the outer periphery of the first pivot shaft 9 in a state in which the transmitter section 2 is pivotally supported. This coil spring 9b is fixed at one end to the first pivot shaft 9 and at the other end to the housing 21 of the transmitter section 2, so that the coil spring 9b protrudes from the stored state with respect to the transmitter section 2. It provides the turning force for transitioning to the state. On the other hand, the transmitter section 2
A second pivot shaft 10 that projects outward from the housing 21 is provided on the side surface of the housing 21 . This second pivot shaft 10 is a cantilevered shaft, and is attached to the housing 1 of the telephone main body 1.
It is supported by a bearing hole 15 provided in 1. Further, a stopper pin 10a is provided protruding from the periphery of the second pivot shaft 10. This stoppa pin 10
A is for abutting against the casing 11 of the telephone main body 1 to restrict the range of rotation of the transmitter section 2 when the transmitter section 2 shifts from the stored state to the protruding state.

In addition, the chain double-dashed line ◯ in FIG. 3 indicates a state in which the transmitter section 2 is stationary at a position regulated by the stopper pin 10a.

Thus, in the telephone configured as described above, when the button 6a is pressed, the claw 6 moves to the locking part 2a of the transmitter part 2.
As a result, the transmitter section 2 is detached from the coil spring 9b.
The restoring force causes the rotation to a position regulated by the stopper pin 10a. This rotation of the transmitter section 2 turns on the hook switch 8, and the telephone becomes ready for talking. On the other hand, when the call is finished, the transmitter section 2 is manually rotated until its locking section 2a is locked with the claw 6, and then stored in the storage recess 5. This turns off the switch 8 and puts the telephone into a standby state.

Now, the cord 24 pulled out from the microphone 23 of the transmitter section 2 is inserted into the hollow part 9a of the first pivot shaft 9 and guided into the telephone main body 1 with an appropriate amount of bending. It is connected to the printed wiring board 16.

Therefore, if the phone is as described above, the first
A hollow portion 9a is provided in the pivot shaft 9 of the hollow portion 9.
Since a is used as the wiring route for the cord 24 that electrically connects the transmitter section 2 and the telephone main body 1, each housing 1 of the transmitter section 2 and the telephone main body 1
It is no longer necessary to provide openings for wiring in 1 and 21 as in the conventional case. Therefore, there is no need to modify the structure of each housing 11, 21 in order to hide these openings, and as a result, the structure of each housing 11, 21 can be significantly simplified. In addition, in this embodiment, when the cord 24 is inserted into the hollow part 9a, an appropriate amount of deflection is given within the transmitter part 2.
Mechanical forces such as twisting applied to the cord 24 when the transmitter unit 2 is rotated can be significantly reduced, and as a result, disconnections and the like can be eliminated and reliability can be improved.

Note that the present invention is not limited to the above embodiments. For example, not only the first pivot shaft 9 but also the second pivot shaft 10 may be provided with a hollow portion, and the cord may be routed through each hollow portion. Further, the rotating mechanism of the transmitter section 2 is simply a coil spring 9b.
In addition to applying rotational force, the rotational movement may be weighted so that it rotates smoothly. In addition, the diameter and installation position of the pivot shaft, the diameter, shape, size, etc. of the hollow shaft can be modified in various ways without departing from the gist of the present invention.

As described in detail above, according to the present invention, the telephone main body and the transmitter part are connected to the first and second cantilevered shafts.
The first and second pivot shafts are mechanically connected to each other by a pivot shaft, and at least one of the first and second pivot shafts is provided with a hollow portion that communicates between the shaft ends, so that the inside of the casing of the telephone body and the casing of the transmitter body are connected to each other mechanically. An opening for electrical wiring is provided by making a spatial connection with the body and by inserting and wiring an electrical cord between the telephone main body and the transmitter part through the hollow part. It is possible to conduct electrical wiring between the telephone body and the transmitter part without causing any friction or major twisting of the electrical cord, and as a result, it is possible to provide a highly reliable telephone with a simple structure. .
