  • Patent number: 12096850
    Abstract: A cross-brace is disclosed having an elongate rod portion and two claws, wherein a second grip-around portion of the claws can be moved relative to a first grip-around portion of the claws between an open position, in which a rod-form element is accommodated by the claws, or can be removed from the claws, and a closed position, in which the claws can grip around the rod-form element. The first and second grip-around portions are designed to grip around the rod-form element in the closed position in such a manner that a gap (S) remains between free ends of the first and second grip-around portions. Furthermore, the claws comprise an arresting mechanism, which is designed to keep the first and second grip-around portions in the closed position. A furniture-assembly kit having such a cross-brace is also disclosed.

  • Patent number: 11918109
    Abstract: A crossmember is disclosed that includes an elongate rod portion and two latching claws. The rod portion has a central longitudinal axis, a first longitudinal end and a second longitudinal end substantially opposite the first longitudinal end. The first latching claw is arranged at the first longitudinal end of the rod portion and the second latching claw is arranged at the second longitudinal end of the rod portion. The first latching claw and the second latching claw each include a gripping portion shaped to correspond to a rod-shaped element and are designed to be mounted on the rod-shaped element without tools. The gripping portion of the first latching claw is offset from the gripping portion of the second latching claw with respect to the central longitudinal axis of the rod portion.

  • Publication number: 20230389698
    Abstract: The present invention relates to a cross-brace (4) having an elongate rod portion (41) and two claws (42), in the case of which a second grip-around portion (423) of the claws (42) can be moved relative to a first grip-around portion (422) of the claws (42) between an open position, in which a rod-form element is accommodated by the claws (42), or can be removed from the claws (42), and a closed position, in which the claws (42) can grip around the rod-form element. The first grip-around portion (422) and the second grip-around portion (423) are designed here such that they grip around the rod-form element in the closed position in such a manner that a gap (S) remains between a free end (4224) of the first grip-around portion (422) and a free end (4231) of the second grip-around portion (423). Furthermore, the claws (42) comprise an arresting mechanism, which is designed to keep the first grip-around portion (422) and the second grip-around portion (423) in the closed position.
