Solar protection or closure unit e.g. door, actuating device, has control unit differentiating variation of parameter of door leaf and obstacle interaction and variation resulting from action of thrust and cover, where unit controls jack

摘要

#CMT# #/CMT# The device has a control unit acting on a jack to interrupt and/or invert the functioning of the jack according to value and/or variation of a parameter representative of interaction between a door leaf and an obstacle on a path, where the jack drives the leaf between two end positions. The jack has thrusts and a cover for limiting the displacement of the leaf at one of the end positions. The unit differentiates a variation of the parameter and a variation resulting from the action of the thrust and the cover. The unit differently controls the jack from the differentiation results. #CMT# : #/CMT# An independent claim is also included for a method for controlling actuation of a door leaf or solar protection by jack between two positions. #CMT#USE : #/CMT# Used for actuating a solar protection or closure unit e.g. door, door leaf, shutter, grid or equivalent material. #CMT#ADVANTAGE : #/CMT# The differentiation results of the control unit permits to ensure the anti-collision safety function and stopping function of the door leaf, when the door leaf reaches one or other of the positions without using a meter or a switch. The activation of the device is simple, rapid and inexpensive. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a block diagram of a solar protection and door leaf actuation control method.
