In placing the telephone set main body 1 on the pedestal 3, the main body 1 is guided by a containment recess 4, placed to the prescribed position of the pedestal 3, the slope 16 of the recess 2 is pressed into contact with the claw 5 of the slider 6 to move the slider 6, the claw 5 is engaged with the engaging recess 2 and the main body 1 is placed surely to the pedestal 3.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an in-vehicle telephone installed in a car, etc.
In particular, it relates to a mechanism for attaching and detaching the telephone body and a cradle that holds the telephone body when not in use.

[Background of the invention]

In order to prevent the phone from falling while the vehicle is running, the phone that is not in use is placed on a cradle that is fixed to the side of the vehicle. ing.

Conventionally, the attachment/detachment mechanism between the telephone main body and the cradle was as follows:
As described in Japanese Utility Model Publication No. 55-51092, a device is known in which a locking piece is provided inside the cradle and is biased by a spring, and the locking piece comes into elastic contact with a part of the telephone body. . However, this conventional example has a structure in which the phone body is removed from the cradle against the elastic force of the spring, so if the elastic force of the spring is too strong, a large amount of force is required to remove the phone body from the cradle. On the other hand, if the elastic force of the spring is too weak, there is a problem in that the phone body may come off the cradle due to the vibrations of the running vehicle.

[Purpose of the invention]

An object of the present invention is to provide a car-mounted telephone that eliminates the drawbacks of the prior art described above, allows the telephone main body to be easily removed from the cradle, and is difficult for the telephone main body to fall off from the cradle due to vibrations of the vehicle. is to provide.

[Summary of the invention]

In order to achieve this object, the present invention provides an engaging recess in the telephone body, a slider that can be engaged with the engaging recess in the cradle, and a release button that is connected to the slider and partially exposed to the outside. The slider is characterized in that it is configured such that the engagement between the slider and the engagement recess is released by pressing the release button.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial vertical cross-sectional view showing an example of an unexploded 1nK car phone, and FIG. 2 is a cross-sectional view showing the internal structure of the cradle in FIG. 6 is a slider, 7 is a coil spring, 8 is an arm, and 9 is a release button.

As shown in FIG. 1, the pedestal 3 is provided with an engaging recess 4 in a portion where the telephone main body 1 is accommodated in a storage recess 4 so as to hold the telephone main body 1 in a stable state. Further, a slider 6 is disposed inside the pedestal 3 so as to be movable in the horizontal direction, and a claw portion 5 protruding from one end of the slider 6 is used to move the slider 6 into the storage recess 4. appear in

As shown in FIG. 2, the slider 6 is constantly urged toward the storage recess 4 by a coil spring 7, and is guided in the horizontal direction by a guide boss 15 vertically disposed from the upper surface of the pedestal 3.

A pair of release buttons 9.9 are rotatably supported on the pedestal 3 by shafts 11.11, respectively, with the slider 6 in between, and similarly, a pair of arms 8.8 are respectively supported by shafts 13.11.
It is rotatably supported by 13. One end of these release buttons 9.9 protrudes slightly from the side wall of the pedestal 5, and the other end is connected to the arm 8.8 via a boss 12.12, and both arms 8.8 are further connected to the boss 14. The slider 6Vc is connected to the slider 6Vc via 14.

Next, the operation of attaching and detaching the telephone main body 1 in the in-vehicle telephone having such a construction will be explained with reference to FIG. 3.

When removing the telephone body 1 placed on the cradle 3 as shown in Fig. 1, first press both release buttons 9 and 9 in the direction of arrow A with finger 1o as shown in Fig. 2. The button 9.9 is rotated about the axis 11.11 to the position shown in dashed lines. Both arms 8.8 are then rotated about the axis 13.13 to the position shown by the dashed line, since the respective bosses 12.12 are engaged with the two release buttons 9.9, so that the arms 8. The slider 6, which is engaged with the boss 14.degree. 14 at the end of the .8, moves against the tensile force of the coil spring 7 to the position shown by the broken line. When the slider 6 moves in this way, the claw portion 5 at the tip of the slider 6 retreats from the storage recess 4, and as a result, the engagement between the claw portion 5 and the engagement recess s2 is released, so that the telephone main body 1 can be removed to the position shown by the broken line in FIG.

Also, place the phone body 1 that was removed from the cradle 3 back on the cradle 3.
When the telephone main body 1 is placed on the cradle 3, the telephone main body 1 is guided by the storage recess 4 and positioned at a predetermined position on the cradle 3. At this time, the slope portion 16 formed below the engagement recess 2 comes into contact with the claw portion 5 of the slider 6 and moves the slider 6. The claw portion 5 of 6 engages with the engagement recess 2, and the telephone main body 1 is securely attached to the cradle 3.

In the above embodiment, the case where both release buttons 9.9 are pressed and the telephone main body 1 is removed is explained, but it is also possible to perform the same release operation by pressing either one of the release buttons 9. evening. In this case, one finger 1o
It is possible to lift the telephone body 1 while holding the telephone body 1 and pressing the release button 9 with the bent finger, improving operability.

Further, the force for pressing the release button 9 can be made stronger or weaker by appropriately selecting the tension of the coil spring 7.

In this way, in the above embodiment 1, the telephone main body 1 can be reliably attached by the engagement between the engagement recess 2 and the claw part 5 of the slider 6 in the storage opening IAJ of the cradle 3 (furthermore, the release button By pressing 9 to disengage the engagement recess 2 from the claw 5, the telephone main body 1 can be easily removed from the cradle 3, resulting in improved operability compared to conventional devices.

〔Effect of the invention〕

As explained above, according to the present invention, the telephone main body can be reliably attached to the pedestal by the engagement of the engaging recess and the slider, so that it is possible to prevent the telephone main body from falling due to equal pressure vibrations of the vehicle. This problem can be resolved, and the phone main body can be easily removed from the cradle by pushing the release button from outside the cradle, thereby providing an in-vehicle telephone with good operability without the drawbacks of the above-mentioned conventional technology. evening.
