Definitions

  • the invention relates to seating furniture according to the preamble of the claim 1.
  • the invention has for its object the generic Train seating so that it is simple and inexpensive can be manufactured so that damage clothing is excluded.
  • the wire ends are not on the top of the seat part and the back part provided, but on the facing each other Attached to the inside of the frame parts. Come through this the wire ends not with the clothes on the seating Person taking a seat. So is one Damage to clothing excluded. As a result of training according to the invention do not have the wire ends be separated because they are in the area between the Frame parts lie. This makes it simple and inexpensive Manufacture of the seating furniture guaranteed.
  • the seating furniture has a seat part 1 and a back part 2.
  • the seat part 1 has a tubular frame 3, the two to each other parallel frame parts 4 and 5, each merge into a front frame part 6.
  • the side frame parts 4, 5 run straight and are from the front frame part 6 in the direction of the back part 2 slightly inclined downwards (Fig. 3).
  • Fig. 2 Of the front frame part 6 is concavely curved (Fig. 2) and symmetrical to the longitudinal center plane 7 (Fig. 2) of the seating educated.
  • the tubular frame 3 has advantageous circular cross-section so that it does not sit disturbs.
  • the tubular frame 3 goes into a tubular frame 8 of the back part 2 over. It has two sides, in the same one Level with the frame parts 4, 5 of the seat part 1 lying Frame parts 9 and 10, which run straight and from Seat part 1 are inclined backwards.
  • the lateral frame parts 9, 10 go arcuately into one upper frame part 11 above, according to the front view Fig. 2 is concave and curved as well as the front Frame part 6 of the seat part 1 symmetrical Longitudinal center plane 7 of the seating furniture runs.
  • the frame part 11 is curved in plan view (FIG. 4) educated.
  • the radius of curvature of the frame part 11 is chosen so that the person sitting on the seating on Back is optimally supported.
  • the upper frame part 11 in a plane that is perpendicular to one of the side frame parts 9, 10 of the back part 2 containing level runs.
  • the front frame part 6 the after is bent below (Fig. 2 and 3), has a larger Radius of curvature as the upper frame part 11.
  • the lateral frame parts 9, 10 of the tubular frame 8 are about half the length by a cross strut 12 (FIG. 2) interconnected, the ends of which face each other Sides of the frame parts 9, 10 attached, preferably are welded on.
  • the cross strut 12 has how 2 and 6 results in angular cross section and has on its back facing away from the seat part 1 over its length extending recess 13 on the extends from the upper edge 14 of the cross strut.
  • the depth of this recess 13 corresponds at least to that Diameter of wires 15 of the back surface 16 forming wire mesh.
  • this wire mesh 16 by approximately perpendicular intersecting wires 15 and 17 formed by which the wires 15 from the cross strut 12 to upper frame part 11 run parallel to each other.
  • the Wires 17 extend between the side frame parts 9 and 10 of the tubular frame 8.
  • the back surface 16 is corresponding to the upper frame part 11 to the rear arched (Fig. 3), the curvature of the back surface 16 is constant over its height.
  • the cross strut 12 is in curved in the same way (Fig. 3) as the upper frame part 11. As shown in FIG. 3, the cross strut 12 lies in a plane that is perpendicular to that of the side frame parts 9, 10 containing plane runs.
  • the cross strut 12 is parallel to the upper frame part 11, extends however, less far back than the frame part 11.
  • the cross strut 12 convexly curved over its length, but less so strong than the upper frame part 11 and the front frame part 6. From Fig. 2 it also follows that the front Frame part 6, seen in front view, more curved runs as the upper frame part 11.
  • the upper ends 18 of the upward wires 15 the back surface 16 are bent backwards at right angles (Fig. 3) and on the underside of the upper frame part 11 attached, preferably welded.
  • the lower ends of wires 15 lie in the depression 13 of the cross strut 12. These wire ends are on the extending in the vertical direction, facing away from the back part 2 flat back 19 of the recess 13 attached, preferably welded (Fig. 3 and 6).
  • the wires 15 are advantageous so long that they have their lower ends also on the perpendicular to the back 19 Sit on the bottom 20 of the recess 13.
  • the upper, right-angled ends 18 of the wires 15 extend approximately to the height of half the diameter of the upper frame part 11. This allows them on the one hand securely on the underside of the frame part 11 are attached, on the other hand they are not inferior rear over the frame part 11 over. Since the wire ends 18th are attached to the underside of the frame part 11, you then do not have to do it in a separate operation be separated, as in conventional Seating with wire mesh is necessary as the back surface is. Since the wire ends 18 do not have the frame part 11 survive, there is no risk that clothes damaged when sitting on the furniture. Because the deepening 13 in the cross strut 12 on the back surface the lower side is provided Wire ends also covered, so that they the Can not damage clothing either.
  • the wires running approximately parallel to the cross strut 12 17 are bent at right angles at both ends.
  • one end 21 of the wire 17 is shown.
  • the other wire end is bent accordingly at right angles.
  • These wire ends 21 are also in relation to the back surface 16 bent back so that there is no danger is that they damage clothing.
  • This Wire ends 21 are on the mutually facing inner sides the side frame parts 9 and 10 attached, preferably welded on. These wire ends extend over a little more than half the diameter of the frame parts 9, 10 to the rear. As a result, the wire ends stand 21 not to the rear over the tubular frame 8 also these wires 17 are not in a separate operation be severed at their ends.
  • the wires 17 are the back surface 16 in the amount of the part 22 having the rear side 19 the cross strut 12. These wires 17 have the same curvature like the cross strut 12, so that at the transition from the Cross strut 12 to the wire mesh 16 no paragraph formed becomes.
  • the upward wires 15 are on the back of the wires 17 facing away from the back surface provided and connected to these.
  • the seat 23 (FIG. 4) is also covered by a wire mesh formed, the crossing wires 24 and 25 exists. These wires cross each other - just like the wires 15 and 17 of the back surface 16 - rectangular.
  • the wires 24 run parallel to the front frame part 6, so they are concavely curved like this.
  • These wires 24 extend between each other opposite side frame parts 4, 5 of the Tubular frame 3. Both ends 26 of the wires 24 are rectangular bent down and facing each other Inside of the side frame parts 4, 5 attached. These wire ends 26 in turn extend only about a little more than half the diameter of the side Frame parts 4, 5 so that they do not have this survive. Therefore, these wire ends 26 do not have to be separated in a separate operation.
  • the wires 24 are at the top the frame parts 4, 5, so that at the transition from the Frame parts to the wire mesh no paragraph is formed.
  • the wires 17 of the back surface 16 also lie, as shown in FIG. 6 shows, at the level of the front of the side frame parts 9, 10 and the upper frame part 11, so that on Transition from the back surface 16 into the frame parts 4 to 6 also no paragraph is formed, which when leaning would be perceived as disturbing.
  • the wires 25 of the seat 23 are on the underside the wires 24 welded.
  • Your front ends are 27, 3 shows, bent downwards at right angles and on the inside of the front part facing the back part 2 Frame part 6 attached.
  • the wire ends 27 extend turn just a little over half the diameter of the frame part 6, so that these wire ends are not protrude downwards over the frame part. That's why they have to Wire ends 27 also not in a separate operation be separated.
  • the cross strut 28 is at the ends mutually facing inner sides of the frame parts 4 and 5 attached, preferably welded. 5 shows is provided on its underside with a recess 29, which extend over the entire length of the cross strut 28 extends and into which the ends 30 of the wires 25 protrude.
  • the depth of the recess 29 corresponds to the thickness of the Wire ends 30 on the back surface 31 of the recess 29 are attached.
  • the wire ends 30 are advantageously located with its face at a right angle to the back surface 31 lying bottom 32 of the recess 29. In The wire ends are thus towards the seat surface 23 30 through the part 33 having the back surface 31 the cross strut 28 covered so that there is no risk that the wire ends 30 damage the clothing can.
  • the cross strut 28 is in the same way as the front Frame part 6 and the wires 24 curved.
  • Fig. 2 On the underside of the frame part 4, 5 of the seat part 1 are two elbows 34 and 35 attached (Fig. 2), the are each L-shaped.
  • a Fixed cross strut 38 Through which the seat part 1 is sufficiently stiffened.
  • the legs 36, 37 have each have at least one opening 39, 40 through which Screws, threaded bolts and the like can be inserted can to the cross strut 38 with its ends on the legs 36, 37 rests, releasably with the elbows 34, 35 to be able to connect.
  • This can be bow-shaped Clamping tabs 43 and 44 are used, the Grip ends of the cross strut 38 and on the legs 36, 37 are attached.
  • the seat 23 and the back surface 16 are different are bent, there is an optimal fit Adaptation and a high level of seating comfort. Since the Tubular frames 3 and 8 integrally formed with each other are, the overall frame 3, 8 has only one Weld on. Because the wire ends of the back surface 16 and the seat 23 forming wire mesh lie on the tubular frame 3, 8 also result manufacturing advantages. So the coating the tubular frame should be made much thinner, since the wire ends will not be cut off afterwards have to.
  • the wire mesh has rectangular meshes that make you special result in high seating comfort. Of course the wire mesh can also have any other suitable structure exhibit.
