Abstract
A device (10) designed to be placed between a gate (12) and a powered actuator (16) to permit release on command and free movement of the gate with respect to the actuator. The device comprises a first plate (11) designed to be fastened to the gate and a second plate (17) designed to be connected kinetically to the actuator. A first and a second plate are supported to rotate freely around a common rotation axis (13) designed to coincide with the gate rotation axis. Means of bolt engagement (18) are arranged to engage between them a first and a second plate to make them integral. Two operating levers (19,20) each arranged on one side of the device and having cam surfaces (31,32) to cause independent backing of the bolt (24) of the engagement means (18) against the thrust of elastic means (25) to move it towards a disengagement position upon movement of one of the two operating levers from a rest position to an operating position. Locks (22,23) can be provided to prevent inappropriate operation of the levers.
