Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handset hook structure for holding a handset of a mobile radio device such as an automobile telephone.

[0002]

2. Description of the Related Art An on-vehicle handset is required to have a hook structure that holds it so as not to drop it from a predetermined position due to vibrations during movement and can be easily removed as needed. Conventionally, as such a hook structure, a structure as shown in FIGS. 5 and 6 has been proposed. That is, a slide hook 34 biased to the left in the drawing by a coil spring 33 is installed in a hollow inside of a pedestal 35 provided in the center of a cradle 32 on which the handset 31 is placed so as to be slidable in a substantially horizontal direction. is doing. The tip of the slide hook 34 is exposed to the front from the pedestal 35, and in FIG. 5 showing the state in which the handset 31 is stored and locked, the jaw portion provided on the lower surface of the handset 1 facing the pedestal 5 is shown. The projecting tip is inserted into the locking hole 36 formed in, and the cradle-side projection 38 engages with the locking recess 37 provided at the tip of the handset 31,
It is configured to hold that position.

When the handset 31 is removed, the hand is put in the gap S between the handset 31 and the cradle 32, and the handset 31 is pivoted upward about the engaging recess 37 and the protrusion 38. Due to the contact between the inclined surface of the tip of the slide hook 34 and the inner wall of the locking hole 36, a component force that moves rightward in the drawing acts on the slide hook 34, pushing back the coil spring 33 and sliding slide 3
4 is released from the locking hole 36, and the handset 31 is in a free state.

When the handset 31 is returned to the storage position, the handset 1 is placed in the cradle 3 in the reverse order of the above procedure.
Mounted on 2 and protruding slide hook tip 34a
May be pushed downward by the inclined surface of the jaw of the lower surface of the handset 31, and the horizontal component force generated thereby may be used to push the slide hook 34 back to the right and introduce it into the locking hole 36.

[0005]

In the conventional hook structure, the handset 31 has to have a large pressing force of the coil spring 33 for urging the slide hook 34.
There is a risk that the handset 31 will come off, and when removing the handset 31, it is necessary to grasp it and pull it up with a certain amount of force to overcome the biasing force of the coil spring 33. However, it is necessary to provide a large clearance space between the handset 31 and a finger so that there is a drawback that the mounting efficiency is lowered and the design is not preferable.

The present invention solves the problems of the prior art and allows the handset to be attached and detached with a relatively small force, and the design is complete without providing a large space between the handset and the cradle. It is intended to provide a hook mechanism.

[0007]

The object of the present invention is to provide an in-vehicle telephone of the type in which a handset is positioned and housed in a recess in the upper surface of a cradle that conforms to the shape of the cradle. Incorporating a vertically movable hook button and a horizontally movable slide hook, each of which is urged by a spring so that its tip projects outward through a slit formed in the wall surface of the pedestal. Are connected by an interlocking mechanism to cause the slide hook to retreat by pushing down the hook button, and the handset is provided with a locking hole with which the tip of the slide hook can be engaged. In the front, a push-up part that applies upward biasing force to the front region of the handset positioned here Is achieved by the handset hook structure of a vehicle-mounted telephone, characterized in that a.

[0008]

In the state where the handset is stored, the force of the spring for urging the hook button and the own weight of the handset are balanced, and the hook button is pushed down halfway. The tip of the slide hook protrudes from the pedestal and enters the locking hole of the handset, and its position is fixed.

In use, when the handset is first pushed down, the hook button is lowered against the biasing force of the spring,
The slide hook retracts via the interlocking mechanism, and the tip of the slide hook comes out of the locking hole and retracts into the pedestal. At the same time, the front region of the handhook is lifted by the action of the lifting member. Then, when the handset is lifted, the hook button rises due to the biasing force of the spring, and the tip of the slide hook moves forward and projects out of the pedestal, but the front area of the handhook is lifted, so the locking hole It doesn't get in.

When the handset is placed on the pedestal after use,
The hook button is pushed down based on its own weight, the slide hook retracts via the interlocking mechanism, and at the same time, the tip of the slide hook is elastically slid into the locking hole by being guided by the lower surface of the handset and the position of the handset is adjusted. Fix it. Hereinafter, the present invention will be described in more detail with reference to the preferred embodiments shown in the drawings.

[0011]

1 is a partially cutaway side view of a telephone showing a structure of a handset hook structure of the present invention. In order to accommodate the handset 2, a concave portion 3 having a shape complementary to the lower curved surface of the handhook is provided on the upper surface of the mountain-shaped cradle 1, and a pedestal 4 is formed in the central portion thereof. ..

In the inner space of the cradle 1, there is installed a hook button 6 which is constantly urged upward by a coil spring 5 and whose tip protrudes to the outside through a slit formed in the wall surface of the pedestal 4, and pushes the tip. It is possible to descend by. Further, a slide hook 8 which is always urged to the left side of the drawing by a coil spring 7 is installed, and a tip 8a thereof projects forward through the slit, and by pushing this, it is possible to retreat in the horizontal direction.

The hook button 6 and the slide hook 8 are connected to each other via an interlocking mechanism 9. As shown in FIG. 2, the interlocking mechanism 9 includes a guide pin 10 protruding left and right from the body of the hook button 6, and a triangular window provided on a U-shaped member 8b of a fork-shaped slide hook 8. 11 and the guide pin 10 and the window 1
By engaging with 1, the two are linked.

The operation of the interlocking mechanism 9 will be described. When no load is applied to the hook button 6 from above,
As shown in FIG. 3a, the hook button 6 occupies the highest position by the biasing force of the coil spring 5, and the slide hook 8
Occupies the most advanced position by the biasing force of the coil spring 7.
Therefore, the guide pin 10 is located at the right corner A of the triangular window 11. When the hook button 6 is pushed down, the guide pin 1
0 moves toward the corner B along the hypotenuse of the triangular window 11,
Along with this, a component force to the right in the figure acts on the slide hook 8 to move it backward (FIG. 3b). Hook button 6
When is pushed down to the intermediate position, the slide hook 8 also occupies the intermediate position as shown in FIG. 3c. In this way, the forward / backward movement of the slide hook 8 is controlled according to the up / down position of the hook button 6.

A push-up member 13 biased upward by a coil spring is installed on the bottom wall surface in front of the pedestal 4,
A pushing force is applied to the front area of the stored handset 2. On the other hand, on the handhook side, a locking hole 12 having a shape corresponding to the tip 8a is provided in the jaw region 2a facing the tip 8a of the slide hook 8 when stored in the recess 3 of the cradle. Further, a locking concave portion 14 is formed on the tip surface of the hand hook and corresponds to the protrusion 15 on the cradle side.

As shown in FIG. 1, when the handset 2 is housed in the recess 3 of the cradle, the locking recess 14 at the tip of the handset 2 is locked by the protrusion 15 and the hook button 6 is held. Is a balance between the weight of the handset itself and the biasing force of the coil spring 5,
It is in a state of slightly lowering than when there was no load. Correspondingly, the slide hook 8 also occupies a position slightly retracted from the most advanced position, but still enters the locking hole 12 of the handset 2 and the handset 2 is stably fixed at that position.

To remove the handset 2 from the cradle 1, a pressing force is applied to the handset 2 on the cradle 1 and the hook button 6 is pushed further downward from the position shown in FIG. Then, as described above, the slide hook 8 is retracted to the position shown in FIG. 3B, and the tip 8a thereof is released from the locking hole 12. This is shown in Figure 4a. Then, the lifting member 13
Rises and pushes up the front of handset 2. This causes the handset 2 to disengage from the locked condition and be removable as shown in Figure 4b. At this point, the hook button 6 is raised to the highest position, and the slide hook 8 is in the most forward position.

On the contrary, in this state, the handset 2 is inserted into the recess 3
When placed inside, the hook button 6 is pushed down by the weight of the handset 2 and the slide hook 8 retracts a little. At the same time, the jaw region 2a of the handset 2 contacts the tip 8a of the slide hook 8, and the cam action of both causes the slide hook 8 to slightly retract and then elastically enter into the locking hole 12, Return to the state shown and lock the position of the handset.

[0019]

As described above, according to the present invention, since the handset can be securely fixed by the special hook structure without requiring excessive force, a finger is inserted when the handset is detached as in the conventional case. It is not necessary to provide a space for the cradle on the cradle side, which increases the mounting efficiency and increases the degree of freedom when designing the telephone.
