摘要:
An operator assembly for shifting a movable barrier between open and closed positions thereof, wherein the operator assembly can be configured to function with a variety of different barrier sizes and orientations. The operator assembly may include one or more interchangeable transmission components for adapting the operator for use with different gate sizes and installations. The operator assembly may also comprise a substantially linear drive train for permitting use with different barrier orientations.
摘要:
A universal power operator for shifting a movable barrier, such as a gate, and a circuit control system for operation thereof, is shown that allows the operator to be assembled for both a left-hinged or right-hinged movable barrier. The universal power operator includes generally an actuator arm, a housing assembly, a gear assembly, and a modular drive motor. The housing assembly contains generally symmetrical portions allowing the user to interchangeably assemble the motor in one of two positions for use with a left-hinged or right-hinged movable barrier.
摘要:
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.
