A hinge for movably supporting at least one cover element on a stationary structure includes a first fitting portion to be arranged on the stationary structure, the first fitting portion having a bearing surface configured to bear against the stationary structure, and a second fitting portion configured to be arranged on the cover element. The hinge includes a hinge lever mechanism having at least on hinge axis, the two fitting portions being movable by the hinge lever mechanism substantially linearly between a first end position corresponding to a closed position of the cover element, and a second end position corresponding to an open position of the cover element. The hinge axis extends inclinedly to the bearing surface of the first fitting portion.

A guide system is provided for movably supporting a cover element for covering an opening in a stationary structure, the cover element being movable by the guide system between a closed position, in which the cover element covers the opening, and an open position, in which the cover element is spaced apart from the opening substantially orthogonally. The guide system includes at least two hinges, each of the hinges including a first fitting portion to be arranged on the stationary structure, a second fitting portion to be arranged on the cover element, and a hinge lever mechanism configured to move the two fitting portions substantially linearly between a first end position corresponding to a closed position of the cover element, and a second end position corresponding to an open position of the cover element. A synchronization device synchronizes a movement of the fitting portions of the at least two hinges.

A guide system for movably supporting a cover element for covering an opening in a stationary structure includes a first assembly for arranging on the stationary structure and second assembly for arranging on the cover element. A first guide device allows the two assemblies to be moved relative to each other in a first movement direction, and a second guide device allows the two assemblies to be moved relative to each other in a second movement direction that is transverse, in particular orthogonal, to the first movement direction. A blocking device can be arranged in a blocking position in which a movement of the second assembly along the second movement direction can be braked and/or blocked, and in a release position, in which a movement of the second assembly along the second movement direction is substantially uninfluenced by the blocking device.

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.

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.
