AI Technical Summary
Existing methods for stiffening furniture carcasses, such as base cabinets with continuous worktops, are costly and require complex assembly, especially in modular setups, and often increase packaging volume.
A crossbeam with headed pins at each end that lock into keyhole-shaped recesses, allowing tool-free assembly and disassembly, featuring a U-shaped cross-section with angled ends for enhanced mechanical stability, made of sheet metal.
The crossbeam provides inexpensive, easy assembly and disassembly while maintaining sufficient mechanical stability, eliminating the need for additional top panels or strips.

Abstract
Description
[0001]18-07-2025-43067201-H au Po s*-0040 PCT / DE2025 / 000075 EW 271 / 25 PCT Traverse Description The invention relates to a traverse for connecting two opposing components, as is known and proven in various embodiments. Particularly in kitchen units that have a multitude of base cabinets with a continuous worktop, the stiffening of a furniture carcass forming such a base cabinet is regularly achieved by a top panel, or optionally by two strips of a wood-based material between the side panels. This is both expensive and involves complex assembly, which, especially with modular furniture carcasses, is usually not possible without tools. Furthermore, such a top panel or two strips increase the volume of, for example, the packaging of a disassembled piece of furniture.Against this background, the invention aims to provide a small crossbeam for connecting two opposing components, in particular two walls of a furniture carcass, which is inexpensive and easy to assemble and disassemble. This technical problem is solved by a crossbeam with the features of claim 1. In particular, such a crossbeam is designed so that, along its length, at least one headed pin is provided at each end of the crossbeam 18-07-2025~43067201-Haup tpss $-0041 PCT / DE2025 / 000075. vorstehtSuch a pin, preferably having a mushroom-shaped, optionally a hammer-shaped head, locks into place by undercutting after insertion into a keyhole-shaped recess. As a result, the crossbar according to the invention can easily absorb both tensile and compressive forces. Assembly is achieved by simply inserting the head of the crossbar into the keyhole-shaped recess without tools and then sliding it, preferably in a horizontal direction, or vice versa for disassembly. The crossbar according to the invention is preferably made of a sheet metal. This crossbar achieves sufficient mechanical stability through a U-shaped cross-section forming two legs. This stability is further increased by the fact that the free ends of the legs each have a fold.In a further design feature of the crossbeam, it is provided that at both ends along its longitudinal axis, the crossbeam has an angled section that supports the pin and lies in a plane transverse to its longitudinal axis. In particular, it is intended that the angled section points in the direction of the legs. This design offers several advantages. For example, this angled section can be easily produced from an extension of a back section connecting the legs, with the legs and the angled section being bent in a single operation. 18-07-2025-43067201-HauP*Post-0042 PCT / DE2025 / 000075 As already explained at the outset, the crossbeam according to the invention is particularly suitable for the manufacture of a furniture carcass in which the crossbeam connects the opposing side panels. The invention is explained in more detail with reference to the drawing, which illustrates only one embodiment and its use.The drawing shows: Fig. 1: a side view, foreshortened representation of a T. raverse Fig. 2: a top view, of arrow II in Fig. 3: an enlarged view of detail III in Fig. 2, Fig. 4: an isometric view, Fig. 5: an enlarged isometric view of an end face and Fig. 6: the use of two crossbeams for connecting the opposing side parts of an M öbelkorpusThe illustrations of the traverse according to the invention show that a pin 2, 3 projects from each end of the traverse along its length. The pins 2, 3 each have a head 4, 5 at their free ends, in this case in the form of a so-called mushroom head. The heads 4, 5 of the pins 2, 3 lock into keyhole-like recesses 6, 7, cf. Fig. in the components to be joined, Fig. 6 by way of example in the side parts 8, 9 of a furniture carcass 10. 18-07-2025-4306720 l-Hsu Pi Post-0043 PCT / DE2025 / 000075 The traverse has a U-shaped cross-section through which two legs 11, 12 are formed. The mechanical stability of the traverse is further increased by the provision that the free ends of the legs 11, 12 each have a groove 13. In the longitudinal extension, two bends 20,21 are provided at the ends of the traverse, which point in the same direction as the legs 11,12.These bends 20, 21, essentially curved extensions of the back 22 connecting the legs 11, 12, support the pins 2, 3 with heads 4, 5. The connection between the pins 2, 3 and the bends 20, 21 can be made in various ways, for example by screwing or riveting, or optionally by gluing or welding. In this embodiment, a core 25 with teeth 26 is fixed to the bends 20, 21, onto which a plastic molded part 27 with a sleeve 28, which supports the head 29, is pressed (see Fig.), with the teeth 26 engaging in the plastic material of the sleeve 28. Fig. shows the connection of the two side parts 8, 9 of the furniture body 10 by two crossbeams 30, 31. If necessary, a third and possibly further crossbeams could be provided for connecting the side parts 8,9, e.g. a crossbeam that engages in the recess and an opposite one.The traverse 31 can also be inserted into the recess and an opposite one, so that the groove 32 for receiving a back panel (not shown) lies behind the traverse 31, not as shown in the Fig. davor 18-07-2025-43067201 -HauP Po st-0044 PCT / DE2025 / 000075 When using crossbeams 30, 31, a separate top is not required for the furniture carcass 10. The carcass 10 is covered by a worktop (not shown). The back 22 of the crossbeam has further openings 33, 34, which may be used to fix such a worktop by screwing it in place. können
