An assembly includes a drive device, a component movable relative to a wall element and intended for closing an opening in the wall element, and a guide device, by which the component is movable relative to the wall element. The component is movable with respect to the guide device orthogonally relative to a longitudinal extent of the guide device by the drive device.

An assembly includes a drive device, a component to be displaced relative to a wall element for closing an opening of the wall element, and a guide device with which the component can be displaced relative to the wall element. A switch and/or a sensor system, preferably a metal detector, allows a partially open position of the component to be detected and/or allows the drive device to be activated, preferably based on a detection of the partially open position starting from a fully open position, and/or allows the drive device to be deactivated, preferably based on a detection of the partially open position starting from a closed position.

A guide system is provided for movably supporting a cover element for covering an opening in a stationary structure. The guide system includes a first guide rail and a first guide body movably arranged thereon, a second guide rail and a second guide body movably arranged thereon, and a compensation device for compensating for a tilting moment of a cover element. The cover element can be moved by the guide system between a first position and a second position, and the compensation device has a cable connecting the first guide body and the second guide body together. A deflecting device allows the cable to be guided orthogonally to the longitudinal extension of the first guide rail and/or the second guide rail at least in some regions, preferably in a region between the first guide rail and the second guide rail.
