Door lock |
摘要 |
A door lock includes a cooperating bracket and hasp having aligned openings for receiving a pin. In the locking position of the pin, in which the pin is received through the aligned openings, a transverse hole in the lower end portion of the pin is aligned with a vertically elongated slot in a wall of the bracket for receiving a security member to prevent upward movement of the pin out of the openings. The openings are shaped to have aligned outwardly extending longitudinal grooves which receive a longitudinal flange on the pin. A cam member pivots between pin blocking and pin releasing positions and has a flat lower flange with a vertical hole therethrough. The hasp has a flat upper wall with a hole therethrough aligned with the hole in the cam member lower flange for receiving a security member to prevent movement of the cam member from its pin blocking position to its pin releasing position.
