  • Publication number: 20240115040
    Abstract: A furniture element, in particular a support or shelf having at least one storage level, has a carcass having at least one support surface, and a translational-rotation fitting for allowing a translational-rotational movement of the carcass relative to a carrier plate of the fitting from a starting position into an open position, and back. The carcass can be moved, relative to the carrier plate, out of a starting position, into an intermediate position, and further into an open position, and back. In an intermediate position, the carcass is rotated in a rotational direction and is displaced in a predefined direction; a guide channel that specifies the direction is provided in the carrier plate, in which guide channel a guide carriage is displaceably received. There is at least one self-retraction apparatus coupled to the guide carriage and is situated on a side of the carrier plate facing away from the carcass.

  • Patent number: 11937693
    Abstract: A shelf or rack includes at least one support plane and having a carcass and a bottom panel. Mutually facing support surfaces of the carcass or a support panel attached to an underside of the carcass and the bottom panel each have at least one groove in which rolling elements are guided. The carcass is movable relative to the bottom panel from a starting position into an intermediate position and further into an open position and back. In the intermediate position, the carcass is rotated in a direction of rotation relative to the bottom panel and is displaced in a predetermined direction. An opening and/or closing mechanism with a force accumulator assisting an opening and/or closing movement of the carcass is arranged on a surface of the bottom panel facing away from the carcass.

  • Patent number: 11849840
    Abstract: A drawer has a device for securing a movable rail of a pullout guide on the drawer, and a support arranged on a side panel, on which a U-shaped holder is provided. The movable rail is insertable with a front end section into the U-shaped holder and the movable rail is lockable on the support and/or holder via at least one catch, which engages through at least one opening on the movable rail, wherein the drawer has a front panel. A method for installing a drawer on a movable rail of a pullout guide uses the device.

  • Publication number: 20220330696
    Abstract: A pullout guide comprises a stationary guide rail which can be fixed to a body, a middle rail which is movably held on the guide rail via first rolling elements arranged in a first rolling element cage, a running rail which is movably held on the middle rail via second rolling elements arranged in a second rolling element cage, and an opening on the middle rail for a support element, which, in a retracted position of the pullout guide, supports the running rail on the guide rail, the support element being mounted on the middle rail such that it can be lowered. In this case, the opening for the support element can be passed over by at least one second rolling element. This allows the support of the running rail to be optimized.

  • Patent number: 9581305
    Abstract: A method for the arrangement of a retaining ring (10) for holding a light source in the opening (11) of a reflector (12) for a vehicle headlamp. The retaining ring (10) extends in a plane and is arranged on the back side flush with the opening (11) on the reflector (12). For the arrangement of the retaining ring (10) of the reflector (12), a molded retainer part (13) is arranged on the reflector (12) and a recess (14) is formed in the retaining ring (10). The retaining ring (10) is placed on the reflector (12), so that the molded retainer part (13) is guided through the recess (14), after which the retaining ring (10) is turned in the plane of its extent about the molded retainer part (13), so that the retaining ring (10) clamps on the molded retainer part (13).

  • Publication number: 20160178153
    Abstract: A projection module for a headlight of a vehicle with a lens holder for receiving a projection lens. On the lens holder is arranged a reflector on which can be received a light source. The lens holder comprises locking tabs, into which can lock counter-locking means provided on the reflector by moving the reflector to the lens holder from an axial direction (A) so that the latching connection is formed for a holding arrangement of the reflector on the lens holder. A headlight of a vehicle may include such a projection module. A method for the mounting of the projection module is also envisioned.

  • Patent number: 9108564
    Abstract: A holder for a light source in the opening of a reflector for a vehicle headlamp, includes a retention ring extending in a ring plane, for an arrangement on the reflector, wherein the light source can be retentively arranged in the opening of the reflector. To allow a safe arrangement of the light source in the opening of the reflector and to prevent that a number of retention rings can get entangled, it is provided according to the invention, that the retention ring has tongues holding the light source in the opening of the reflector by means of elastic spring deflection, the tongues having a first tongue end and a second tongue end, and wherein the tongue ends lie essentially on the ring plane of the retention ring.
