Door, window, or French window type opening, has opening frame and motorization unit for controlling movement of opening frame and including motor housed in central pole on which opening frame is articulated

摘要

#CMT# #/CMT# The opening has an opening frame e.g. ventilation leaf, and a motorization unit (40) for controlling the movement of the opening frame and including a motor (12) housed in a central pole (5) on which the frame is articulated. A unit (44) transmits the rotation movement of a drive shaft (45) of the motor to the opening frame through a rotation axle of the opening frame. The motorization unit (40) includes a speed reducer (22) and a torque limiter (13) placed in the central pole. #CMT#USE : #/CMT# Used for a door, window and a French window (all claimed). #CMT#ADVANTAGE : #/CMT# The use of the motor does not alter the esthetics of the opening and maintains the performance of the opening, while maintaining the air and water sealing property and acoustic and thermal insulation property of the opening and minimizing transmission kinematics of the movement of the opening frame. The device simplifies the transmission of the rotation movement to the opening frame. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a partial exploded perspective view of a central pole. 5 : Central pole 12 : Motor 13 : Torque limiter 22 : Speed reducer 40 : Motorization unit 44 : Drive shaft rotation movement transmitting unit 45 : Drive shaft.
