Actuating mechanism for automatic door or gate has at least one actuator linked to hydraulic motor on frame support to rotate door or gate

摘要

#CMT# #/CMT# The actuating mechanism for opening or closing an automatic door or gate (3) comprises at least one actuator (1) mounted on a frame support (2) to turn the door or gate about its vertical axis of rotation. The actuator is rotated by a reversible hydraulic motor-pump (4) associated with a closed hydraulic circuit and mounted on an upright support member (31), the dimensions of the motor being small enough to fit within the support's width. The actuator(s) can have gear mechanisms to convert a lengthwise motion of the motor into a rotary motion of the actuators, at least one of which incorporates a lock. #CMT#USE : #/CMT# Automatic door or gate operating mechanism. #CMT#ADVANTAGE : #/CMT# The actuating mechanism is compact and suitable for use by handicapped persons. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of the actuating mechanism and part of a door or gate. 1 : Actuators 2 : Frame 3 : Door or gate 4 : Motor 31 : Support member 32, 33 : Upper and lower edges of door or gate.
