Abstract

The object of this invention is to provide an apparatus for preventing mis-locking of furniture. When a drawer is closed into a body, a protruding button of a back plate is pressed by a body frame, drawn inwardly while compressing a spring. The shape of another side of the locking board is selected to be a crouching U or an inverted L shape. When a lock body is utilized to lock up, it engages with the back plate, thereby entering the crouching U or inverted L shape of the back plate, so as to complete the locking-up action. When the drawer is drawn out, the protruding button disengages from the body frame, and throws out, utilizing the elasticity of the spring, the back plate moves consequently and retain the locking board by being urged against the installing board. Under this circumstance, the locking-up operation cannot be performed because the lock board fixed on the lock body is urged against the back plate even if one intends to lock-up, so as to prevent the collision damage of the body caused by the lock board.
