Abstract (en)
[origin: WO9409239A1] Device for motorised opening and closing of folding doors, panel doors, folding gates and panel gates, in the following referred to as doors, wherein the door is opened and closed by means of a motor drive transmission acting on the door and which, independent of the direction of movement of the door, will disengage the door, so that the door is released and will stop in case of an obstacle, independent of a continued motor motion. The device is characterized by a power transmission member (1) which is non-disengageably connected to the drive shaft (13) of the motor drive and rotatable about a centre (18) of rotation coaxial with said shaft; a disengageable lever (2) which also is rotatable about said centre of rotation (18); a double-armed lever (4) which also is rotatable about said centre of rotation (18); a disconnection unit (3) provided to releasably connect the disengageable lever (2) with the moment lever (4), said unit (3) being provided to release the moment lever (4) from the disengageable lever (2) if the door is hindered by an obstacle in its range of movement.
