ABSTRACT:
A door which is to be swung open and closed to provide access to an enclosure and slid back into the enclosure is provided with one or more hinges rotatably mounted on a shaft to the ends of which there are fixedly mounted gears which positively engage respective racks disposed adjacent the top and bottom of the enclosure and extending along the depth of the enclosure so that as each door is slid in and out of the enclosure there is no rotation of the door in its plane and, hence, no sagging and binding of the door. A portion of each hinge is confined within a guide block which is in turn rotatably connected with the shaft and slidably mounted in a channel adjacent and parallel to the rack so that only the member of the hinge attached to the door is swingable with the pivot of the hinge being rectilinearly slidable with the door along the depth of the enclosure.
