Claims

[Scope of Claim for Utility Model Registration] (1) A hook piece that rotates when the door is locked and extends between the sliding door and the doorstop, a movable bearing member that pivotally supports the hook piece, and a movable bearing member that rotates in a straight line. A guide member that guides the reciprocating movement and a biasing force that moves the hook piece forward and backward along the moving direction of the movable bearing member and rotate it in the locking direction when moving forward and in the unlocking direction when moving backward. and a means for preventing the movable bearing member from advancing relative to the guide member at the most advanced position of the movable bearing member, and at this most advanced position, the hook claw is activated by the force acting in the forward or backward direction of the operation member. Each piece can be rotated in the locking or unlocking direction, and by providing an abutting means that prevents the hook piece from rotating in any other retracted position, the force acting on the hook piece of the operating member can be moved forward or backward. A single-piece sliding door lock characterized by being designed to act in one direction. (2) Claim (1) characterized in that the hook piece has a recess in a direction transverse to the direction of movement from its rotation axis, and the operating piece of the operating member is engaged in this recess. A single-piece sliding door lock as described in . (3) The abutment means for preventing rotation of the hook piece is the guide member when the hook piece rotates in the locking direction, and the abutment means when the hook piece is rotated in the unlocking direction. The single-piece sliding door lock according to claim (1) or (2), characterized in that it is an inner surface of the member.
