摘要:
The invention concerns a drive for closing devices, for example gates or shutters, with variable speed output drive and a device for detecting a given position of the closing device. According to the invention, the drive speed output depends on the position of the gate and can be controlled depending on the given mechanical closing characteristic of the closing device.

A drive for doors, in particular garage doors, having door runners which are in each case arranged laterally and which are guided in fixed position rails, and having a drive unit having at least a motor and a driving gear. The drive unit has two rope pulleys arranged to oppositely rotate, with the two free ends of a respective rope being wound on each rope pulley. The rope ends cooperate with the door runners such that the door can be opened or closed via the rotational movement of the rope pulleys.

A connecting element for holding at least one profiled belt end comprises at least two parts which can be connected to one another and in the installed state, enclose the belt end. One or more of the parts have sections with a negative profile corresponding to the belt end. The belt end is inserted into one or more of the parts in manner such that connection is formed-locking in all directions that deviate from the direction of the joint.

The present invention relates to a control system for a door drive with a plurality of components and a digital data bus via which the components communicate, wherein at least one safety component such as a closing edge-safety device or a light barrier detects safety-relevant events and reports the same via the data bus. When detecting a safety-relevant event, the safety component blocks the communication via the data bus for a certain time, wherein the remaining components detect the missing communication on the data bus and interpret the same as notification of a safety-relevant event.

The invention relates to a method of controlling a door drive having a plurality of components which are communicatively connected to one another via a digital bus system, wherein at least one component is a safety component which reports the occurrence of a safety-relevant event over the data bus, and wherein the bus protocol reserves a cyclic safety phase for reporting a safety-relevant event and at least one component recognizes an undefined data transmission during the safety phase as a report of a safety-relevant event.

The invention relates to a guide skid for a gate drive which is accommodated sliding in a C-profile, with two lateral openings extending over its length to accommodate a drive cord, a locking element for the coupling and disconnecting from the drive cord and a connecting element for the gate to be moved. The guide skid has a symmetrical outline and when installed has no parts projecting beyond the C-profile, and with the guide skid being provided one face thereof with a continuous slot which is bridged by a bolt forming the connecting element.
