Definitions

  • the invention relates to an armrest according to the preamble of claim 1.
  • Such an armrest is known for. B. from the Martin Stoll Collection / N •. It has a U-shaped support bracket with a round tube cross section and two upwardly directed legs, at the base of which a cross member attached to the seat is attached.
  • the arm support is formed by a likewise U-shaped round tube with a smaller diameter and two legs pointing downwards, which is covered with integral foam to form the armrest.
  • Firmly connected plastic sleeves with outer rings are attached to the leg ends of the arm carrier. These plastic sleeves are driven - in the manner of the known plastic champagne corks - into the round tube openings of the carrier bracket.
  • a disadvantage of this known solution with a round tube support bracket and crossmember welded to the base is also the fact that the connection end of the crossmember has to be adapted to the round tube of the bracket and the connection is inevitably within the user's field of vision.
  • the weld seams must be plastered accordingly. Both adapting and plastering are very expensive. If you were to replace welding with brazing, plastering could possibly be saved, but the costs would also be very high.
  • the support bracket also consists of a U-shaped tube, in this case with an oval cross-section, and upward-pointing legs.
  • the armrest has a foam-covered arm support with downward-pointing legs made of flat iron that protrude from the foam. These legs are inserted into the oval tube ends of the support bracket and screwed there.
  • the screw heads are inevitably visible, which the user perceives as unaesthetic.
  • the two known armrests are basically distinguished from other armrests in that the support bracket and armrest form a self-contained annular unit.
  • the aim is to achieve the aesthetically advantageous visual impression of a so-called "ring armrest", which in itself - with the increased manufacturing costs involved - usually consists of a completely foamed metal ring.
  • the costs are to be reduced by the divided structure, but without giving up the formal advantage of the “ring armrest.
  • the known ring armrests have the disadvantages mentioned above.
  • the armrest according to the invention advantageously comprises a maximum of only three different parts: the support bracket, the arm support which runs into the two connecting pieces and the holding clips provided at the ends thereof.
  • the arm support is extremely easy to assemble and disassemble. After assembly, it clamps and wedges itself. With regard to the manufacturing tolerances, no special requirements are placed on the manufacturing quality, since the usual tolerances are compensated for by the type of construction. Nevertheless, the assembled parts are tight and do not come loose even in tough continuous use. This achieves the formal and technical advantages of a ring armrest with significantly reduced manufacturing costs.
  • the support bracket 1 which consists of a U-shaped tube which, as can be seen from Figs. 2 and 3, has an oval cross-section.
  • the tube is bent on its broad side and there are two legs 5, 6 pointing upwards.
  • the armrest consists of an arm support 2, which is covered in a known manner with a suitably shaped cushion 17, preferably an integral foam.
  • the arm support 2 consists of flat material, preferably sheet steel or plastic, which is profiled in the arm support area K. As can be seen from FIG. 4, a 3-U profile is selected here. The profiling and design of the flat material is such that it transmits the arm support forces acting on the support bracket 1 without deformation.
  • the arm support 2 is therefore rigid.
  • the profiling ends in the material thickness, so there is no longer any profiling here.
  • the arm support 2 can be punched and pressed very inexpensively. Casting or injection molding of plastic is also possible.
  • Installation is simple and inexpensive by inserting the connecting pieces 3, 4 of the arm support 2 into the leg openings 7, 8 of the support bracket 1 by hand or by machine.
  • the connecting pieces 3, 4 are symmetrically wedge-shaped in the edge region of the support bracket, the width of the wedge from a value above to a value below the value of the inside diameter of the receiving part of the leg openings 7 , 8 of the support bracket 1 decreases. In the case of the oval cross section according to FIGS. 2, 3, this inside diameter is therefore the largest inside diameter that occurs, or the distance between the two narrow sides that form the receiving part of the leg openings 7, 8.
  • the symmetrical wedge-shaped design of the connecting pieces 3, 4 in turn reduces the requirements on the manufacturing tolerances.
  • the wedge brings about an advantageous wedging of the connecting pieces 3, 4 in the leg openings 7, 8 of the support bracket 1, in particular if the pitch angle of the wedge is smaller than the friction angle or the friction coefficient of the material pairing of the connection piece support bracket.
  • the angle should therefore be less than 8 degrees.
  • the connecting pieces 3, 4 penetrate into the leg openings 7, 8 to different depths, depending on the dimensions. This would create an aesthetically disturbing gap between the cushion 17 and the support bracket 1.
  • the pad 17 advantageously has a circumferential lip 18 covering the transition of the connecting pieces 3, 4 into the leg openings 7, 8 of the carrier bracket 1.
  • the ends of the connecting pieces 3, 4, which are seated within the legs 5, 6 of the support bracket 1, each have resilient retaining clips 9, 10 intended. They are preferably made of spring steel or a material with resilient properties, and are supported on the one hand on the connecting pieces 3, 4 and on the other hand on the inner wall of the legs 5, 6 of the support bracket 1.
  • the retaining clip 9 comprises only a spring collar, which is supported between the connector " 3 and the inner wall of the leg opening 7.
  • a resilient leg of the retaining clip 9 encloses the end of the The connecting piece 3 is pressed against the end and effectively wedged in the pipe cross-section by the considerable spring forces of the supporting leg and the tolerances between the pipe inside diameter and the ends of the connecting piece 3 are fit automatically balanced, and there is a second play-free seat below the wedge.
  • this seat at the end of the connecting piece 3 this is kept narrow above the end, and only the end itself has a value which is slightly smaller than that smallest value of the largest occurring inside diameter of the profile pipe.
  • FIG. 4 Such an embodiment is shown in FIG. 4.
  • the retaining clip 9 has barbs 14 on the one hand, and a retaining lug 13 on the other hand, which engages in an opening of the connecting piece 3.
  • the obliquely upward barbs 14 do not interfere when the arm support 2 is inserted into the leg opening 7. However, they cling to the wall of the tube when the arm support 2 is pulled upwards, provided that the material of the barb 14 is harder than that of the support bracket 1.
  • the retaining lug 13 ensures that when the arm carrier 2 is replaced, the retaining clip 9 is in any case also pulled out of the leg opening 7 and can be replaced if necessary.
  • the retaining clip 10 has two spring collars, which are supported on both sides of the connector 4 on the tube wall of the bracket 1.
  • the outer leg of each spring collar in turn has barbs 14 which claw into the wall of the support bracket tube.
  • the embodiment with the two spring collars of the holding clip 10 brings about an even greater holding force than the holding clip 9 with only one spring collar.
  • the connecting piece 4 is held in the middle of the support bracket tube, that is to say not pressed against the inner wall of the tube as in FIG. 2 and wedged there.
  • the lower end of the connecting piece 4 is somewhat wider than the larger one according to a further idea of the invention. ste occurring inner diameter of the support bracket tube executed, and provided in the end a longitudinal slot 12. This is shown in Fig. 5. This allows the two end parts of the connecting piece 4 to deflect resiliently towards the center and wedge against the pipe wall on both sides with the magnitude of the spring force.
  • the arm support can also be made of plastic in addition to steel, preferably by injection molding. This is particularly useful and cost-effective when there is no upholstery covering and the entire armrest is made of one piece.
  • the connectors 3, 4 are then part of the armrest itself.
  • the retaining clip 9, 10 can be made from z. B. plastic. They can also be molded onto a plastic arm support so that the number of individual parts is further reduced. Since in this case the barbs 14 of the softer plastic could not catch in the metal wall of the carrier bracket 1, according to a further idea of the invention, recesses 15 in the form of impressions or small recesses are provided in the inner wall thereof, in which the barbs 14 engage.
  • both the support bracket 1 and the cross member 11 now consist of a U-shaped profile tube with an oval cross section, which is bent on its broad side.
  • the leg opening 16 of the cross member 11 is integrally bonded to the underside of the base of the support bracket 1.
  • the armrest according to the invention is particularly suitable for office seating furniture with a central pedestal, in which ring armrests are preferably used.
  • the armrest can also be attached directly to the seat.
