SUMMARY OF THE INVENTION In the above lock device,
If the length of the lock release cable 8 and the dimensions and assembly state of each part of the lock mechanism 1 are the same on the left and right, the operation lever 2
When the lock mechanisms 1 are operated, the respective lock mechanisms 1 are simultaneously operated left and right via the joint mechanism 2, the rotation angles of the left and right lock levers 7 are also exactly the same, and one lock mechanism 1 has been released but the other lock mechanism It does not occur that 1 does not enter the release state.

However, in general, the length of the unlocking cable 8, the dimensions of each part of the lock mechanism 1 and the assembled state are not the same on the left and right due to manufacturing errors and installation errors, so that the operation lever 21 of the operation mechanism 3 is full. Even if the block 18 of the joint mechanism 2 is moved to the limit by rotating the lock mechanism 1, only the lock of one lock mechanism 1 is released, and the lock of the other lock mechanism 1 may not be released. In order to avoid such a situation, it is necessary to set the rotation angle of the lock lever 7 to be sufficiently large, which causes a problem that the joint mechanism 2 becomes large.

In view of the above-mentioned circumstances, the present invention provides a lock release cable and an operation cable for reliably releasing the lock of the lock mechanism even when the rotation angle of the lock lever is small, that is, even when the stroke of the lock mechanism is small. It is intended to provide a cable joint mechanism.

[0016]

According to the present invention, one block is fitted in a casing so as to be reciprocally slidable in the axial direction, and the block can be pulled in the axial direction by operating the operating mechanism. A plurality of unlocking cables capable of separately unlocking the locks of the plurality of lock mechanisms are connected to the operating cable from the side opposite to the side on which the operating cable extends . To cable side
Through the block so that it can be moved in the axial direction, and the end of the cable for operation of each of the unlocking cables
At the end, so as to be located closer to the operation mechanism than the block,
Attach stoppers, and between each stopper and block
At the same time, when the operation cable is pulled , a resilient body that bends by a predetermined amount to tension each unlock cable is released.
It is arranged so that it may be wound around each cable .

[0017]

When the operation cable is pulled by operating the operation mechanism, the block moves, and the plurality of lock release cables are also pulled by the block, respectively. Therefore, the lock release cable moves and the lock of the lock mechanism is released. You. At this time, the unlocking cable pulled to the stroke end cannot move any more because the elastic body shrinks even if the block moves, but the unlocking cable not pulled to the stroke end moves further. Therefore, even if the lock mechanism is small and the rotation angle of the lock lever is small, the lock by the lock mechanism can be reliably released.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 to 3 show an embodiment of the present invention. The feature of this embodiment resides in a joint mechanism 2.
Except for the above, it is the same as the joint mechanism of the conventional unlocking cable and operating cable shown in FIGS.

That is, in this embodiment, the two unlocking cables 8 are connected to the block 1 of the joint mechanism 2.
8, the end of the lock release cable 8 on the block 18 side extends to the side where the operation cable 22 extends through the block 18 in the axial direction D, and a stopper 23 is provided at the end. A coil spring 24 is disposed between the stopper 23 and the block 18 so as to wind the unlocking cable 8 and apply tension to the unlocking cable 8.

When releasing the lock of the lock mechanism 1, FIG.
When the operation lever 21 is rotated counterclockwise in
The operation cable 22 causes the block 18 of the joint mechanism 2 to move rightward along the axial direction D, and the block 1
The two unlocking cables 8 also move rightward via the coil 8 and the coil spring 24, respectively.

For this reason, the lock lever 7 of each lock mechanism 1 is also pulled by the lock release cable 8 in FIG.
The lock lever 7 rotates counterclockwise about the pin 6, the peripheral edge 7 b of the engagement hole 7 a of the lock lever 7 is separated from the neck 12 b of the lock pin 12, and the front panel 10 moves away from the lock base 5 about the pin 9. By rotating in the direction, the front panel 10 can be opened.

In such an operation, one of the two unlocking cables 8 is pulled to the stroke end, the lock lever 7 also rotates to the limit, and the lock on the lock pin 12 is released. However, the other unlocking cable 8 is not pulled to the stroke end, and therefore the lock lever 7 connected to the unlocking cable 8 does not rotate to the limit and the lock is not released. , The operation lever 21 is further rotated clockwise in FIG.

Then, the unlocking cable 8 of the two unlocking cables 8 which has not been pulled to the stroke end is further pulled rightward in FIG. 1 to the stroke end via the block 18 and the coil spring 24. The lock lever 7 also rotates to the limit, and the lock on the lock pin 12 is released. Since the unlocking cable 8 that has been pulled to the stroke end cannot move further rightward in FIG. 1, the corresponding coil spring 24 is moved by moving the block 18 rightward as shown in FIG. 3. At a predetermined amount.

As described above, the two unlocking cables 8 are inserted into the block 18 of the joint mechanism 2 so as to be movable, and are fixed to the ends of the unlocking cables 8 protruding toward the operation cable 22. By providing the coil spring 24 between the stopper 23 and the block 18, even if one of the unlocking cables 8 reaches the stroke end, the other unlocking cable 8 that has not reached the stroke end is further moved. It is not necessary to make the stroke of the two unlocking cables 8 an overstroke, so that the lock can be reliably released without making the rotation angle of the lock lever 7 unnecessarily large. And the whole apparatus can be made compact.

In the embodiment of the present invention, the case where two sets of the lock mechanism 1 are provided has been described. However, any number of sets may be used as long as the number of sets is two or more, without departing from the gist of the present invention. Needless to say, various changes can be made.

[0027]

According to the joint mechanism of the lock release cable and the operation cable of the present invention, the lock of the lock mechanism can be reliably released even if the stroke of the lock mechanism is small , and the structure is simple. Surely
Can be performed and maintenance is easy.
Costs can be reduced, and
Can slide in the axial direction, and water and dust
There is no risk of entering, and blocks and elastic bodies cause malfunctions
Various excellent effects can be achieved.
