DESCRIPTION:
BRIEF SUMMARY
FIELD OF TECHNOLOGY
The invention concerns objects with forward and subsequent lateral displacement of forward movable surfaces, particularly display cases, cabinets and doors, the common opening characteristic of which is the combination of the forward displacement of the surface closing the volume of the object with the subsequent movement of this surface to any side.
BRIEF DESCRIPTION OF THE RELATED ART
Objects with forward moving doors are known in which the lower and upper parts of the moving doors are provided with a tipping or forward moving mechanism enabling the forward movement of the forward movable doors. Once the doors have been moved forward they are supported on guide rails which allow their subsequent lateral movement. This arrangement is used in forward moving doors of e.g. rail-bound and other vehicles. The arrangement of forward moving and guiding mechanisms in both the lower and the upper parts of forward movable doors is a disadvantage in some applications of forward movable doors. The cumbersome character of this design manifests itself markedly e.g., in the application of forward movable doors to display cases or similar applications in the furniture industry.
An analogous problem of forward movable doors is addressed by the Austrian Patent No. 295,072. Built into the cabinet floor there is a rocking adjustable member controlled by a lever mechanism mounted in solid wall components. The fronts of the solid wall components and the sliding door are in one plane in a closed position. By means of the rocking adjustable member the lever mechanism shifts the door provided with rolls onto the adjacent rail along which they can move laterally. The lever mechanism controlling the rocking adjustable member is complicated and necessitates firm mounting in the solid front wall of the cabinet. controlling the rocking adjustable member is complicated and necessitates firm mounting in the solid front wall of the cabinet.
The French Patent No. 149,950 concerns sliding plates, such as doors and glazing covering openings. Lateral movement of glass is enabled by the wheels moving in grooves which simultaneously prevent glass oscillation in a vertical plane.
The U.S. Pat. No. 4,112,622 concerns a roller assembly for sliding screen doors. It describes the mounting of a roller, rotating on a pin firmly fastened to lateral sides forming a roller housing. The lateral sides of the roller housing are held together by adequate stress between the lateral housing sides and lateral walls of the channel in which the roller housing is located.
The U.S. Pat. No. 2,508,972 concerns the design of a device for the closing of large and heavy doors of airplane hangars and the like. The door frame is provided with a part with a cut and the lateral part of the door is provided with a pin matching the cut after closing. The U.S. patent also concerns a set of sliding doors. To facilitate the door movement a spring is inserted between the sliding roller and the lateral part.
The Austrian Patent No. 339,531 describes extendable overlapping doors for furniture pieces. Two or more adjacent extendable doors in a closed position of the object are in the same level plane. In the opened position of the object the doors are superimposed one in front of the other and can be shifted by means of rollers in a channel-like groove fastened on the adjacent door. Their lateral guidance is in a straight line, and by means of rollers, on which they are suspended. The doors run in a V-groove of an extender, which is extendable in a direction perpendicular to the lateral guidance of the door. The extender moves by its edges by means of the rollers between two rails fastened to the side walls of the case and to the intermediary ceiling of the case. The rails situated on both side walls of individual compartments of the case together with the rollers which are a part of the extender provide for the extension of the door. The rails are perpendicular to the plane of the extended door. Each extendable door requires its own rail assembly. The whol
