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.

Dependent claims

A guiding system for moving suspended panels, the panels being fixedly connected to a trolley and said trolley running on a track, the track having a first track portion, a second track portion transverse to and intersecting the first track portion, and the track having a running surface and an opening disposed in a bottom portion of the track, the opening having a width, said guiding system further comprising:

four support rollers disposed on said trolley;
said trolley comprising a roller cage for supporting said four support rollers and having at least one side surface with sides, said sides comprising two sets of opposite sides;
said four support rollers being mounted on said at least one side surface of said roller cage, wherein each of said four support rollers is disposed on a corresponding horizontal axle for rotating freely about said corresponding horizontal axle;
said four support rollers comprising two pairs of support rollers wherein one pair of said two pairs of support rollers is disposed on said opposite sides of each said set of opposite sides of said roller cage;
each said side having a corresponding vertical edge portion;
each of said four support rollers being mounted on a corresponding one of said sides;
each said support roller of each said pair of support rollers being configured for rotating about an axis of rotation;
a substantial portion of each of said four support rollers projecting, in a radial direction of each said support roller, beyond the corresponding vertical edge portion of its corresponding side, the radial direction being defined in a direction perpendicular to said axis of rotation of each said support roller and perpendicular to the corresponding vertical edge portion;
another portion of each of said four support rollers diametrically opposed to said substantial portion intersects with a plane which is coaxial with a vertical center axis of said roller cage and normal to said corresponding one of said sides;
said axes of rotation of each said pair of support rollers being parallel and displaced a substantial distance from one another;
and
each said pair of support rollers being configured for making contact with and running on the running surface of the track.
