Abstract: A drive for closure elements is provided, in particular in the area of garage and industrial doors, but also for example in the form of roller shutters, with a reference value generator arranged in the motor or in the gearing of the drive for determining the actual position of the closure element. When a reference point position is reached, the reference value generator emits a signal or causes a signal modification, on the basis of which the actual-value generator can be calibrated. The reference value generator has two reference discs rotating in different speeds, which, in predetermined angular positions to one another, define the reference point positions which can be scanned by at least one scanning device.

Abstract: The present disclosure relates to a door drive housing comprising a base support body, preferably of shell shape, and a covering hood which can be connected to the base support body, wherein a base plate made as a sheet metal part can be inserted into the base support body consisting of plastic for the reception of the different drive components.

Abstract: The present disclosure relates to a garage door drive comprising a covering hood covering the drive unit, with at least one recess being cut-out in the covering hood which can be covered via a panel which can be placed onto the covering hood.

Abstract: The present disclosure relates to a spindle nut which, as part of a drive device, is connected to a tube, wherein the spindle nut has a substantially cylindrical shoulder in which at least two recesses are cut out, wherein a tube is pushed over the cylindrical shoulder of the spindle nut and wherein the tube is deformed toward the recess in the region of the recesses such that the deformed regions contact the walls of the recess.

Abstract: A garage door power module is provided with the capability of operating over a number of different operating frequencies by configuring a power module chassis with a receptacle for receiving radio receivers where each of the receivers is adapted to receive one of the frequencies. The receptacle located near one edge of the chassis and is configured with a planar surface and support members that permit the receivers to be slidably inserted and removed from the receptacle. In addition the radio receiver is equipped with a plug connector and the receptacle is equipped with a socket for receiving the plug connector in order to transmit radio control signals from the receiver to logic control circuits in the power module.

Abstract: A garage door drive includes a housing and at least one light unit. According to the invention, at least one mounting point for the mechanical and electrical connection of the attachably and detachably constructed at least one light unit is arranged on the housing.

Abstract: The present invention relates to an apparatus to suspend garage door drives that are fitted with a drive unit and a guide rail, preferably a C-shaped guide rail. The apparatus typically includes a rail with assembly holes and a clamp to engage around the guide rail. The rail has respective plate-like widened sections at the sides which carry folded prolongations at diagonally opposite end edges which can engage around the guide rail like a clamp.
