Electric drive coupling for window opener - has connecting features for actuator ensuring different modes of power actuation

摘要

The electrical drive for window openers has a lifting device which is coupled to the drive motor. This lifting system is used for skylights which are too high for manual actuation. A single motor can be used for actuation of a number of opening rods owing to the coupling design. This motor can actuate right hand and left hand or closed opening mechanisms. This reduces stored quantities and production is more economical. The lifting element (6) which actuates the opening rod (34) has a number of connecting features in the form of tapped holes (16, 17) for optional connecting of coupling elements (9) which are connected to opening rods. The coupling elements are pushed through slots (30) in the housing walls (8, 12).
