The hook lock is particularly adapted for sliding gates where it may be fixed on the surface or within the gate itself.
<??>The lock comprises an electromagnetic solenoid (19) with related magnetic shell (17), a cylinder lock (38) with key, a device in the form of a hook (4) and a system of five rocker levers (13, 16, 23, 26, 33) activated by a spring compressed plunger (3), said elements arranged in a rectangular metal box (1).
<??>The whole is assembled in such a way that every time the solenoid (19) receives an electrical impulse, the magnetic shell (17) is attracted and releases the system of rocker levers (13, 16, 23, 26, 33). The combined action of the latter automatically releases and raises the hook (4); the inverse blocking action occurs automatically when the gate closes.
<??>The lock is mechanically opened manually by using the appropriate key. |
