  • Patent number: 6532626
    Abstract: The invention concerns an adjustable hinge that connects two furniture/cabinet components (door and cabinet body) together by means of a cabinet hinge and baseplate. On the cabinet hinge is a spring snap mechanism and connected on it, a hinge arm. This is connected by an adjustment plate with the baseplate and between the hinge arm and adjustment plate, an adjustment screw is located to adjust the both (bilateral) distances. The adjustment screw is screwed through an enclosed elongated hole in the adjustment plate in a thread borehole in the hinge arm. According to the invention, the adjustment screw is designed as a set screw (thread pin), which has on its one end a device for a releasable coupling with a tool and on the other end has a plate with a larger diameter. The bottom surface side of the plate, thus, rests on the baseplate and on the plate's upper surface, the edge of the adjustment plate's elongated hole.

  • Patent number: 6390574
    Abstract: A fully extendible drawer unit utilizes two pairs of, in each case, three rails which can be pushed into one another. On the carcass rail is positioned a differential roller, which allows the intermediate rail to be moved along when the drawer starts to be pulled out at a lower speed than the drawer and the drawer rail. A coupling lever ensures that the intermediate rail is still pushed along even when the drawer rail has already left the differential roller and that this happens synchronously.
