Guide system for movably supporting at least one cover element for covering an opening in a stationary structure

A method for covering and opening at least one opening in a stationary structure by at least one cover element, comprising:

• moving the at least one cover element between a closed position, in which the at least one cover element covers the at least one opening, and an open position in which the cover element is spaced substantially orthogonally from the at least one opening, wherein the movement of the at least one cover element takes place in a first movement direction,
• moving the at least one cover element between the open position and a displacement position in which the at least one cover element is arranged laterally offset relative to the opening, wherein the movement of the at least one cover element takes place in a second movement direction transverse, in particular orthogonal, to the first movement direction, and
• transferring at least one blocking device from a blocking position, in which the at least one blocking device brakes and/or blocks movement of the at least one cover element along the second movement direction, to at least one release position, in which movement of the at least one cover element along the second movement direction is substantially unaffected by the at least one blocking device, and vice versa.
