Abstract: A support and guide system for movable door or wall elements is disclosed, which system comprises stationary ceiling channels with channel junctions. Running in the ceiling channels are trolleys from which the door or wall elements are suspended through a gap in the ceiling channel. The trolleys feature trolley rolls which are rotatable about horizontal axles which are located on the side edges of a square. Provided in the areas of the channel junctions are additional support elements, in the ceiling channels, for trolley support. To enable a material- and weight-saving design, the support elements are inserted in the ceiling channels, on support arms, at a specified spacing above the trolley, while above the trolley there is a support plate mounted which is supportable from underneath by the support elements.
