[0002]

2. Description of the Related Art In order to improve the inconvenience of unlocking a door by first pressing a door push button and releasing a latch, the door must be unlocked and then the door must be opened by a door handle. As disclosed in FIG. 3, a pull-type locking device (Japanese Patent Publication No. 2-359) capable of unlocking and opening the door continuously by simply pulling the operation knob of the door.
No. 68) has already been proposed. In this case,
The lock device main body A is attached to the door back surface d1 on the open end side D1 of the hinged door D on the door mounting frame F by screwing or the like. The lock device body A has a door surface d of a door D.
Pull pusher A1 penetrating through hole d3 drilled toward side 2
The operation knob B is attached to the door surface d2 side, and a1 in the figure indicates a pusher of the pull pusher A1.

Further, the lock device main body A is provided with a door back surface d1.
In the hollow casing A2 attached to the
3 and a spring A4, and a pusher a of the pull pusher A1
1 is stacked on the latch body A3, and the sliding contact a2 of the pusher a1 is moved to the cam portion b of the latch body A3 having the latch b1.
It is in contact with 2. Further, the protrusion A4 is interposed between the hollow casing A2 and the latch main body A3, so that the latch b1 of the latch main body A3 is attached to the inner surface f of the door mounting frame F. The latch body A3 is resiliently urged in the latching direction so as to be freely detachable, and presses the inside of the hollow casing A2 toward the above-mentioned latch seat C side so as to be freely retractable.

Therefore, in the case of the known pull-type locking device using the operation knob B as described above, if it is attempted to lock the door as shown in FIG. Latch b1 is hollow casing A
When the door D is closed in this state, the latch b1 comes into contact with the latch seat C, and the latch body A protrudes against the elasticity of the sprout A4.
After 3 moves to the right in the drawing, it is moved back, so that the closed state of the door is ensured by the engagement of the latch b1 with the latch seat C.

[0005] In the above-mentioned door-open locked state, FIG.
As shown in (A), the pusher a1 is connected to the cam portion b of the latch body A3.
2 and the screw rod a of the pull pusher A1
3 is also in the upward movement position, and the operation knob B is also on the door surface d2.
It is arranged on the side. Further, when the operation knob B is pulled toward the front of the door as shown in FIG.
At this time, since the pusher a1 and the door back surface d1 are movable only in a direction orthogonal to the door, the sliding contact leg a2 of the pusher a1 slides with the cam portion b2 which is a pair of the latch body A3. The latch body A3 is contacted, and the latch body A3 is formed by the component force of the pulling force.
And retreats against the resilience of the latch b1 and is released from the latch seat C of the latch b1 to be unlocked. As a result, when the operation knob B is pulled, the door is opened. Of course, when the pulling force is released, the latch body A3 is opened.
Is pushed out to the door mounting frame F side by the spring A4, and the pusher a
Reference numeral 1 in FIG.
Also returns to the same position as the closed door lock state described above, and is held at that position.

[0006]

According to the above-mentioned pull-type lock device, since the door is opened and closed by the operation knob, a sufficiently large pulling force is transmitted particularly when the door is heavy. Because of the difficulty, it has already been proposed to use an operation handle that can be firmly gripped (Japanese Patent Laid-Open No. 9-72142). However, in this case, there is a pair of mounting leg portions bent from both ends of the handle portion of the U-shaped operation handle, and one of the legs is a lock device body as shown in FIG. Connect to the pull pusher, but for the other,
The structure is such that it is simply inserted into the through hole for mounting the door in a state where it cannot be removed.

Therefore, according to the above conventional example, not only is the operability and durability of the operation handle insufficient, but the operation handle having a predetermined size is set in advance, so that the dimensions are different. If the user wants to use the operating handle attached to the door, he has to purchase a pull-type lock device including the operating handle.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks of the prior art, the present invention is designed to attach not only the conventional lock device main body but also the lock device main body and the lock device sub-body to the back surface of the door. Instead of being separated from the device subbody, it is configured to be integrated by the telescopic connecting portion, and by rotating the telescopic connecting portion, the distance between the lock device main body and the lock device subbody can be freely set. This makes it possible to obtain an optimally sized operation handle of various sizes from the operation handle, and to adjust the above-mentioned interval length to the operation handle so as to match the size.

With the above arrangement, the main body-side mounting portion of the main body of the lock device main body can be precisely positioned with respect to the position of the pair of mounting legs of the selected operating handle. Aligns the sub-body-side mounting part of the pulling push sub-body of the lock device sub-body with a simple and quick operation for any size of operation handle, and has durability and operability of the operation handle. The purpose is to try to improve also.
