A support assembly for a chair, the support assembly including a carrier shell, a receiving shell mountable on the carrier shell, and a locking element. The carrier shell and the receiving shell each have, in an edge region, connection structures formed in a manner complementary to one another. The connection structures are configured to engage in one another in the mounted state in such a way that they form a through-channel into which the locking element can be introduced.

A furniture kit is disclosed that includes a set each of floor ladders, longitudinal cross-bars, and longitudinal wind braces. Each of the floor ladders has two vertical supports connected via upper and lower rungs, each of the two vertical supports is equipped with a foot for placement on a floor. Each longitudinal end of the cross-bars is equipped with a latching claw mountable, without tools, on a floor ladder rung. Each of the wind braces is equipped at its longitudinal ends with a clamp designed to be mounted on a rung of a floor ladder by gripping the rung. Cross-bars and wind braces are designed such that a cross-bars can be mounted on upper rungs of first and second floor ladders, while one of the wind braces is mounted on the upper of the first of the floor ladders and the lower of the second of the floor ladders.

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.

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.

The invention is directed to a support assembly for a chair, comprising a carrier shell, a receiving shell mountable on the carrier shell, and a locking element. The carrier shell and the receiving shell each have, in an edge region, connection structures formed in a manner complementary to one another. The connection structures are configured to engage in one another in the mounted state in such a way that they form a through-channel into which the locking element can be introduced.

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. The present invention additionally relates to a furniture-assembly kit ( 1 ) having such a cross-brace ( 4 ).

The invention relates to a cross brace ( 4 ) comprising an elongate bar portion ( 41 ) and two clips ( 42 ). The bar portion ( 41 ) has two substantially opposite longitudinal ends. The two clips ( 42 ) are each arranged on one of the two longitudinal ends of the bar portion ( 41 ) and are designed to almost fully enclose a bar-shaped element ( 22, 52 ). Furthermore, the two clips ( 42 ) can each be brought into an opened position, in which the bar-shaped element ( 22, 52 ) can be received by the clip ( 42 ) and removed from the clip ( 42 ), and into a closed position, in which the bar-shaped element ( 22, 52 ) can be fully enclosed by the clip ( 42 ). The clips ( 42 ) have a lock ( 425 ) which locks the clip ( 42 ) in the closed position.

A crossmember ( 3 ) comprises an elongate rod portion ( 31 ) and two latching claws ( 32 ). The rod portion ( 31 ) has a central longitudinal axis, a first longitudinal end and a second longitudinal end substantially opposite the first longitudinal end. The first latching claw ( 32 ) is arranged at the first longitudinal end of the rod portion ( 31 ) and the second latching claw ( 32 ) is arranged at the second longitudinal end of the rod portion ( 31 ). The first latching claw ( 32 ) and the second latching claw ( 32 ) each comprise a gripping portion ( 321 ) shaped to correspond to a rod-shaped element ( 22, 31, 52 ) and are designed to be mounted on the rod-shaped element ( 22, 31, 52 ) without tools. The gripping portion ( 321 ) of the first latching claw ( 32 ) is offset from the gripping portion ( 321 ) of the second latching claw ( 32 ) with respect to the central longitudinal axis of the rod portion ( 31 ).

A furniture kit is disclosed that includes a set each of floor ladders, longitudinal cross-bars, and longitudinal wind braces. Each of the floor ladders has two vertical supports connected via upper and lower rungs, each of the two vertical supports is equipped with a foot for placement on a floor.
