Description

[Detailed Description of the Invention] The present invention mainly relates to the improvement of a sliding door lock that is attached to a sliding door, which is a Japanese-style fitting, for locking the sliding door.

Conventionally, sliding door locks have been widely used for metal Japanese-style sliding doors such as sliding doors in Japanese-style entrances, glass doors in Japanese-style rooms, and glass doors with paper shoji.

This is because Talentent locks, which are generally used for locking sliding doors in Western-style rooms, are attached to the side of the sliding door's stile, so the position of the lock can be seen from outside, making it ideal for crime prevention. In addition to this, the locks protruding from the sides of the stile make it unsightly and unsuitable for Japanese-style rooms.

However, in the conventional lock for sliding doors, the locking latch is rotatably attached to the internal case attached to the connecting stile or mullion of the internal sliding door through the bundle shaft. It has a structure that can be locked by engaging with a locking shaft attached to a strike box that protrudes outward and is fixed to the connecting stile of the external sliding door, and the latch that tightens has the function of pulling the external sliding door toward the indoor side. However, since it does not have the function of pulling the external sliding door and pressing it against the window frame when it is locked, it is sufficient if the sliding door is incorporated into the window frame with no errors in the building materials, but there are errors in the building materials. The locking latch attached to the striking stile of the internal sliding door or the mullion fixed to the window frame may not fit into the strike box attached to the striking stile of the external sliding door, or even if it does, the latch may not fit into the sliding door. There were various drawbacks such as gaps being formed between the window frame and the window frame.

In order to eliminate the drawbacks of the conventional sickle lock for sliding doors, the present invention aims to change the position of the helaiki box, which can be attached to the mating stile of an external sliding door even if there is an error in the building material, to the mating stile of an internal sliding door or the window frame. The external sliding door can be installed precisely according to the position of the case attached to the mullion fixed to the door, and when the locking is performed, the tightening latch attached to the case is inserted into the strike box. To provide a sickle lock for a sliding door which can be drawn toward the internal sliding door or mullion side, and which can also provide the effect of separating the internal/external sliding door or external sliding door and the mullion to the left and right to improve watertightness and airtightness. be.
