Description

[Detailed Description of the Invention] [Outline] The present invention is capable of giving a degree of freedom to the shape of the other device by concentrating the lock and the mechanism required for releasing the lock on one of the two separable devices. Moreover, the number of parts can be reduced as a whole to reduce the cost.

[Industrial application field]

The present invention relates to a joint lock device for a separable device that locks two separable devices so that they can be contacted and separated from each other.

[Conventional technology]

Conventionally, a locking mechanism between two devices, which are separated when in use and joined when not in use, for example, a handset and a cradle of a car phone, has a second structure.
Some are configured as shown. The device A in the figure is a cradle, and the device B is a handset. In the passenger compartment, the device A is fixed to the vehicle body side, and the device B is removable. In the same figure (a), when the concave portion 2 of the device B is engaged with the fixed claw 1 of the device A and the device B is rotated in the direction of the arrow a with this as a fulcrum, the movable claw 3 on the device A side is the device. It shows a locked state in which it is pushed by the sloping inner wall surface of B and once retracted, then enters the hole 21 of the device B by the repulsive force of the spring 20 and cannot be detached.

To release the locked state, the operation button 6 protruding to the side surface of the device B is pressed with a finger as shown in FIG. When the button 6 is pushed in the direction of the arrow, the link 7 rotates and the arm 5 slides. As a result, when the tip of the arm 5 enters the hole 21 shown in FIG. 7A and the movable claw 3 on the device A side is sufficiently retracted, the push button 4 receiving the repulsive force of the spring 22 pushes up the device B. Therefore, the device B is free to the device A. Reference numeral 23 is a return spring of the arm 5, and 24 is a holder for the movable claw 3 and the push button 4.

[Problems to be solved by the invention]

By the way, in the above-described lock mechanism, since the lock operation unit (3, 20) is provided on the device A side and the lock release operation unit (5, 23) is provided on the device B side, any device is There is a drawback that the internal structure becomes complicated.

The present invention increases the degree of freedom of the shape of the other device by concentrating the lock and its release operation part on one device as much as possible,
Moreover, it is intended to reduce the cost by reducing the total number of parts.

[Means for solving problems]

In the present invention, one device (denoted as A) is provided with a locking claw (11), but both the movable part for locking and the movable part for unlocking are provided in the other device (denoted as B). . Further, both movable parts are realized by a common member (8, 30).

[Action]

The structure described above simplifies the structure on the device A side and increases the degree of freedom in shape. Moreover, the cost can be reduced by reducing the number of parts as a whole.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 1 (a) is a sectional view showing the right half of a car telephone. (The left half is the second
(The same as FIG. (A)). In the figure, 8 is a slide-type hook provided on the device B side for both lock and release, 30 is a return spring thereof, 9 is an on-hook or an off-hook of the handset (switch (not shown) is turned on / off), A block for separating auxiliary pushing up the device B at the time of unlocking, 31 is a rotating shaft of the block, 10 is a leaf spring that gives an elastic force to the block 9, and 11 is a fixed tab for engagement. The fixed claw 11 required for locking is provided on the device A side, but the movable parts 8 and 30 that operate during locking and unlocking are common to simplify the configuration, and these are provided on the device B side. Thus, the device A side has a degree of freedom in shape.

The operation will be described. At the time of locking, the device B is rotated and pressed against the device A side. At this time, since the claw 11 of the device A is fixed, the slide hook 8 on the device B side is spring-loaded.
Slide to the right once against the elastic force of 30 and
When 32 exceeds the claw 11, the hook 8 returns to the left by the force of the spring 30, and the hook is engaged with the claw 11 as shown in the figure, and the hook is locked.

This locked state is released by rotating the operation lever 12 shown in (b) around the shaft 33 and moving the slide type hook 8 again to the right by the inclined surface 34 thereof. At this time, the block 9 on the device A side receives the repulsive force of the leaf spring 10 to push up the device B in an auxiliary manner, so that the devices A and B are in the separated state while the operation lever 12 is being pressed.

The locking mechanism of this example does not require the movable claw 3, the return spring 20, the holder 24 and the link 7 of FIG.
Therefore, the structure can be simplified and the cost can be reduced. still,
The target devices A and B are not limited to car phones.

[Effect of device]

As described above, according to the present invention, the locked state and the separated state of two separable devices can be switched with a small number of parts. Further, since the movable parts are concentrated on one device as much as possible, there is an advantage that the degree of freedom of the shape of the other device is increased.

Furthermore, when the operating lever (12) is operated, it does not accidentally remain locked. Further, the other device can be easily taken out.
