<p>PURPOSE: A door latch is provided to automatically open a home-bar door by the pressing of the door and to close and fix the door by the pressing of the door. CONSTITUTION: A door latch comprises a frame(110), a rotating latch(120), a spring(160), a ball(140). The rotating latch is installed in the frame to be able to rotate by a given angle and comprises a groove(122). A hook(10) formed on a target is selectively fixed while the groove rotates. The spring applies the unidirectional torque to the rotating latch. The ball is installed between the frame and the rotating latch, is movably installed on a path formed between the inner surface of the frame and the rotating latch and selectively limits the rotating angle of the rotating latch to rotate the rotating latch at a fixed angle or at an opened angle.</p> |
