Abstract
This invention relates to a support and guide element for movable, suspended door and wall elements. The support and guide element is designed so that a smooth movement can be securely executed, even in the vicinity of junctions and intersections. This is achieved because four support rollers are fastened to a square support roller cage block, but where only two of the four support rollers support the weight of the door or wall element in the running direction of the door or wall element. The other two support rollers are oriented at right angles to the running direction, and, during movement of the door in the running direction, only come into contact with the roller rail at a junction or intersection. Above the running rollers there are guide rollers, which guarantee secure guidance of the wall element.
