Abstract

PROBLEM TO BE SOLVED: To securely and air-tightly lock a door without enlarging the lock case, by rotating a diving body by a handle and rotating a locking body while sliding a guide hole along a guide shaft through a connection body. SOLUTION: A locking body 5 is connected so as to rotate through a connection body 6 by a driving body 4 and contained in a case 1. The connection body 6 is connected to a trigger 8 through a stopper 9 and a bolt 37 is protruded from a panel 3 and attached to the side end of a sliding door. When the sliding door is closed, the bolt 37 contacts a fitting frame to retract the trigger 8 and the stopper 9 is rotated and removed out of the notch 36 of the connection body 6. When the driving body 4 is turned to the left in this state by a handle, the long guide hole 33 is guided by the guide shaft 16 of the case 1 and the locking body 5 is rotated to the right through the connection body 6. And the key part 31 of the front end is protruded from the panel 3 and fitted to a receive tool of the fitting frame. And the sliding door is pulled to the fitting frame and closely fitted thereto and securely locked.

2. Description of the Related Art Conventionally, in order to enlarge a back set without enlarging a lock case, Japanese Utility Model Application No. 63-11679 has been proposed.
As invented in No. 1 (Japanese Utility Model Laid-Open No. 2-39072), the cam and the sickle member are connected by a link plate, and the operation of the operation knob causes the cam to rotate, and the sickle member to rotate through the link plate to lock. Things to do have been suggested.

[0003]

In the above conventional example, the sickle member simply rotates, so that the sliding door cannot be brought into close contact with the mounting frame, resulting in poor airtightness and rattling of the sliding door. There is a problem that it is easy. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problem in a sliding door sickle lock capable of increasing the back set without increasing the size of the lock case.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problem, the present invention solves the above-mentioned problem by rotating a driving body by an external operation, rotating a locking body through a communication body, and moving the locking body from a side end face of a sliding door. In the sliding door sickle lock in which the sickle part of the locking body in the case protrudes and locks, the locking body is provided with a sickle part at the front end, the rear end part is rotatably engaged with the communication body, and the middle part is An elongated guide hole is provided, the guide shaft provided in the case is inserted through the guide hole, and the lock body is rotatable and the guide hole slides along the guide shaft. It is configured as possible.

[0005]

According to the present invention, the lock is rotatable and the guide hole is slidable along the guide shaft, so that the sickle of the lock is attached to the mounting frame. If it hangs on the attached receiving device, the sliding door can be drawn toward the mounting frame.
