Definitions

  • the invention relates to a wall as a front wall, inner front wall, rear wall, side wall or panel, in particular for a Ausschub, such as. a drawer or the like, consisting of metal, in particular steel, with a closed profile.
  • the DE 20 2014 100 584 U1 discloses a front panel for furniture, in particular for an extract, with a three-part construction, with a central part and two side panels.
  • the front panel is made of plastic and is manufactured by injection molding.
  • Elegant and shapely panels, which should also be lightfast, are difficult to produce or have a large aperture thickness.
  • an extract or a front panel which has a receiving element and an insert plate. Both the receiving element and the insert plate are made of sheet metal, which are held together by a plastic rivet.
  • Such front panels are unsuitable for daily, rough use and usually cause rattling noises.
  • the DE 10 2014 220 091 A1 shows a method by which flat products can be welded together.
  • the free, interconnected in the welding ends must be subjected to a special pre-treatment, which is time consuming and costly.
  • the WO 2012/007452 A1 discloses a solderable fluid channel for an aluminum heat exchanger.
  • this fluid channel it is primarily important that the channel is fluid-tight, ie that neither fluids can enter nor exit.
  • the rigidity of the channel plays a minor role in this case, since the heat exchanger per se by its plurality of fluid channels and its, the fluid channels surrounding frame undergoes its rigidity.
  • the invention has for its object to provide a wall for furniture or furniture parts, which consists of a metal sheet and has a higher rigidity than plastic profiles and a lower weight has as injection molding profiles or extruded profiles.
  • edge regions of the profile are positively, positively and / or materially connected to each other.
  • a hollow profile is created, which on the one hand is stiff, on the other hand has a low weight, since it is made hollow and not, as in the casting variants, consists of solid material.
  • the desired profile is bent and closed the profile at its profile ends.
  • the profile joint is preferably prepared by punching or profiling, so that the profile ends can be positively, positively and / or materially connected to each other.
  • the profile shock is formed below, with the profile legs extend over part or the entire length of the profile.
  • the edge regions of the profile in the form of profile joints as a seam, in particular J seam, stitch seam, I-seam or Y-seam, are connected to each other.
  • the edge areas for the connection do not require any preparation or special distances.
  • the seam has a lap joint.
  • the connection can be carried out as a weld or by means of screws, rivets or the like. In a welded joint, this may be convex or concave. It can run as a point seam or line seam.
  • the seam is located at a crimping impact.
  • the crimp joint may be welded, soldered or glued.
  • the form-fit is a riveting, a clinching or caulking. In particular, these are done on the overlap or crimp with suitable tools.
  • a high rigidity is achieved according to the invention in that the material connection is a soldering or a welding with or without additive.
  • the welding is advantageously carried out by plasma, laser, MIG / MAG, TIG or by press welding. It can be done manually or mechanically, whereby high dimensional accuracy can be achieved.
  • relatively thin sheet metal thicknesses can be interconnected, whereby the weight of the initially bent and then welded profile compared to extruded profiles remains very low, but still has a very high rigidity.
  • a quick connection of the curved profile to a hollow profile and the finished product is achieved in that the weld is a spot weld. Even with long profiles, only a few spot welds are required, e.g. two to three pieces to obtain the desired stiffness for the e.g. To produce trained as a wall profile hollow profile.
  • the welding is carried out by means of electrode welding.
  • the filler material is adapted to the respective profile material and the type and shape of the seam.
  • the laser welding by means of CW (continuous wave) laser or pulsed or pulsed laser.
  • CW continuous wave
  • pulsed or pulsed laser This laser welding has the advantage that despite local fusion of the profile areas only minimal amounts of energy are introduced into the component and therefore no deformation and only minimal discoloration.
  • the invention also relates to a furniture or furniture part having a wall which has one or more of the features mentioned above or in the claims.
  • Such furniture can be produced inexpensively and replace the variants of aluminum.
  • the design of the furniture or furniture parts according to the invention are equal to those of aluminum, so that both embodiments can be used in combination.
  • the stiffness of the components of both steel and aluminum variants are the same or almost the same and do not differ. Further features and advantages will become apparent from the following Bescheidung, in which reference is made to the drawings.
  • Excerpts especially drawers or the like of furniture or pieces of furniture, usually have a wall which is formed by a front wall, inner front wall, rear wall, side wall or panel.
  • FIG. 1 For example, a part of a front wall 10 is shown, but should not limit the invention.
  • the front wall 10 is made of sheet steel and has an inner side 12, an outer side 14, an upper side 16 and a lower side 18, wherein the steel sheet is bent or folded at the edges 20 in such a manner that the free legs forming the lower side 18 face one another, so that they can eg be welded, crimped, glued, screwed, riveted or possibly crimped, what is FIG. 2 It can be seen that shows an enlarged section II of Figure 1.
  • the leg 22 is bent such that it is behind the leg 24, i. within a hollow profile 28 comes to rest and rests against the inside.
  • the two legs 22 and 24 can thereby be connected to one another in a material-locking manner, manually or mechanically, by welding as a seam 30, in particular a J-seam, by means of laser, MIG / MAG, TIG or pressure welding performed via a line seam in the visible region 26 ,
  • the connection can also be done by spot welding.
  • the welding can also take place through the two legs 22 and 24 in the form of a stitch seam 32.
  • the connection of the legs 22 and 24 can also be effected by means of a soldering or gluing.
  • the two legs 22 and 24 prepared by punching or profiling in the form of breakthroughs.
  • FIGS. 3 and 4 show a second embodiment in which the two legs 22 and 24 lie with their end faces to each other, so that the two end faces directly as I-seam 34 welded together, can be soldered or glued.
  • the two outer end faces of the legs 22 and 24 form the underside 18 of the front wall 10th
  • FIGS. 5 and 6 show a third embodiment in which the two legs 22 and 24 as a crimping abut each other and abut their end faces on the inner surface of the outer side 14 of the front wall 10.
  • the two legs 22 and 24 are in this embodiment in the interior of the hollow section 28 and form an additional stiffening rib.
  • the welding takes place in the throat area 26 of the foot ends of the two legs 22 and 24 as a widened Y-seam 36.
  • the two legs 22 and 24 are plated on their facing side surfaces with solder and soldered together, for example in a brazing furnace become.
  • the two legs 22 and 24 can also be riveted or crimped together at the two open ends of the front wall 10.
