  • Patent number: 8474926
    Abstract: A fully extendable telescopic drawer guide for furniture components that can be extended from the body of an item of furniture, with a guide rail facing the body, a running rail associated with the extendable furniture component, and an intermediate rail arranged between these two rails. Rolling elements are provided which are supported in cages and transfer the load of the extendable furniture component by way of rolling surfaces disposed on the rails. At least one rotatably supported supporting roller for the running rail is provided on the front end of the intermediate rail.

  • Patent number: 8336973
    Abstract: A flush-mounted guiding arrangement adjustably mounts furniture parts that are extractably and insertably mounted inside a furniture carcass by means of a pair of extensible guides encompassing one respective guide rail. The sliding rail is longitudinally guided on the guide rail and can be placed in the lateral edge region on the bottom face of the extractable furniture part. An adjusting fixture grips the bottom of the furniture part that is to be mounted and in the forward end area of the sliding rail. The adjusting fixture has a mechanism for adjusting the position of a sliding rail relative to the extractable furniture part in the direction of at least one axis of a Cartesian coordinate system formed by three coordinate axes that run substantially perpendicular to each other.

  • Patent number: 8220602
    Abstract: Damping movement device of pieces of furniture which are movable relative to stationary parts. The device has a cylinder with a piston movable in a longitudinal direction, forming a modifiable working chamber filled with liquid medium. The liquid medium is transferred in a throttled manner. A piston rod is sealingly guided and connected to one side of the piston. The movement of the parts of furniture which is to be damped is transmitted to the piston via the outer end of the piston rod facing away from the piston. A volume compensating mechanism is provided. The piston rod is coupled to the piston with overflow ports. The non-return disk with overflow port is moved into sealing contact with the facing piston face. A spring biasing the facing faces of the non-return disk and the piston into the spaced-apart position is arranged between the non-return disk and the piston.
