Definitions

the invention relates to seating furniture according to the preamble of claim 1.
the wire ends of the wire mesh which form the seat surface and the back surface, are fastened to the respective frame.
the wire ends have to be separated after being fastened to the frame, so that the protruding wire ends do not damage the clothing of the person sitting on the seating furniture.
the manufacture of such seating is therefore complex and expensive. It cannot be ruled out that, even after the protruding wire ends on the seat surface and on the back surface have been severed, sharp edges are still formed by the severed wires, which can likewise damage the clothing.
the invention has for its object to design the generic seating so that it is simple and inexpensive can be manufactured so that damage to clothing is excluded.
the wire ends are not provided on the top of the seat part and the back part, but rather are fastened to the mutually facing inner sides of the frame parts.
the wire ends do not come into contact with the clothing of the person sitting on the seating. Damage to clothing is therefore excluded.
the wire ends no longer have to be cut off since they lie in the area between the frame parts. This ensures simple and inexpensive manufacture of the seating furniture.
the seating furniture has a seat part 1 and a back part 2.
the seat part 1 has a tubular frame 3, which has two mutually parallel frame parts 4 and 5, each of which merges in an arc into a front frame part 6.
the side frame parts 4, 5 run straight and are slightly inclined downwards from the front frame part 6 in the direction of the back part 2 (FIG. 3).
the front frame part 6 is concavely curved (FIG. 2) and symmetrical to the longitudinal center plane 7 (FIG. 2) of the seating furniture.
the tubular frame 3 advantageously has a circular cross section, so that it does not interfere when sitting.
the tubular frame 3 merges into a tubular frame 8 of the back part 2. It has two lateral frame parts 9 and 10 lying in the same plane with the frame parts 4, 5 of the seat part 1, which run straight and are inclined obliquely backwards from the seat part 1.
the lateral frame parts 9, 10 arcuate into an upper frame part 11 which, in the front view according to FIG. 2, has a concave curvature and, like the front frame part 6 of the seat part 1, runs symmetrically to the longitudinal center plane 7 of the seating furniture. While the front frame part 6 of the tubular frame 3, as seen in plan view of the seat part 1 (FIG. 4), runs straight, the frame part 11 is curved in plan view (FIG. 4) educated.
the radius of curvature of the frame part 11 is selected so that the person sitting on the seating furniture is optimally supported on the back.
the upper frame part 11, as shown in FIG. 3, lies in a plane which is perpendicular to a plane containing the side frame parts 9, 10 of the back part 2.
the frame parts 6 and 11 of the seat part 1 and the back part 2 are bent differently.
the front frame part 6, which is bent downwards (FIGS. 2 and 3), has a larger radius of curvature than the upper frame part 11.
the lateral frame parts 9, 10 of the tubular frame 8 are connected to one another approximately in half length by a cross strut 12 (FIG. 2), the ends of which are fastened, preferably welded, to the mutually facing sides of the frame parts 9, 10.
the cross strut 12, as can be seen from FIGS. 2 and 6, has an angular cross-section and has on its rear side facing away from the seat part 1 a recess 13 which extends over its length and extends from the upper edge 14 of the cross strut. The depth of this recess 13 corresponds at least to the diameter of wires 15 of a wire mesh forming the back surface 16.
this wire mesh 16 is formed by wires 15 and 17 crossing each other approximately perpendicularly, of which the wires 15 run parallel to one another from the cross strut 12 to the upper frame part 11.
the wires 17 extend between the lateral frame parts 9 and 10 of the tubular frame 8.
the back surface 16 is curved to the rear corresponding to the upper frame part 11 (FIG. 3), the curvature of the back surface 16 is constant over its height.
the cross strut 12 is 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 which is perpendicular to the plane containing the side frame parts 9, 10.
the cross strut 12 is parallel to the upper frame part 11, but extends less far to the rear than the frame part 11.
the cross strut 12 is convexly curved over its length, but less strongly than the upper frame part 11 and the front frame part 6. It also follows from FIG. 2 that the front frame part 6, viewed in front view, runs more curved than the upper frame part 11.
the upper ends 18 of the upwardly extending wires 15 of the back surface 16 are bent backwards at right angles (FIG. 3) and fastened, preferably welded, to the underside of the upper frame part 11.
the lower ends of the wires 15 lie in the recess 13 of the cross strut 12.
These wire ends are fastened, preferably welded, to the flat rear side 19 of the recess 13 which runs in the vertical direction and faces away from the back part 2 (FIGS. 3 and 6).
the wires 15 are advantageously so long that they also sit with their lower ends on the perpendicular to the back 19 bottom 20 of the recess 13.
the upper, right-angled ends 18 of the wires 15 extend approximately to half the diameter of the upper frame part 11. This allows them to be securely attached to the underside of the frame part 11, on the one hand, and on the other hand they do not protrude rearward beyond the frame part 11. Since the wire ends 18 are attached to the underside of the frame part 11, they do not then have to be separated in a separate operation, as is necessary with conventional seating with wire mesh as the back surface. Since the wire ends 18 do not protrude beyond the frame part 11, there is also no risk of clothes being damaged when sitting on the furniture. Since the recess 13 is provided in the cross strut 12 on the side facing away from the back surface, the lower wire ends are also covered, so that they cannot damage the clothing either.
wires 17, which run approximately parallel to the cross strut 12, are bent at right angles at both ends. 6, one end 21 of the wire 17 is shown. The other end of the wire is bent at a right angle. These wire ends 21 are also bent backwards with respect to the back surface 16, so that there is no risk that they will damage the clothing. These wire ends 21 are fastened, preferably welded, to the mutually facing inner sides of the side frame parts 9 and 10. These wire ends extend a little more than half the diameter of the frame parts 9, 10 to the rear. As a result, the wire ends 21 do not protrude rearward over the tubular frame 8. Thus, these wires 17 do not have to be separated at their ends in a separate operation.
the wires 17 of the back surface 16 lie at the level of the part 22 of the cross strut 12 which has the rear side 19. These wires 17 have the same curvature as the cross strut 12, so that there is no shoulder at the transition from the cross strut 12 to the wire mesh 16 is formed.
the upward wires 15 are on the provided from the back surface facing away from the wires 17 and connected to them.
the seat 23 (FIG. 4) is also formed by a wire mesh which consists of wires 24 and 25 crossing one another. These wires cross each other - like the wires 15 and 17 of the back surface 16 - at right angles.
the wires 24 run parallel to the front frame part 6, so they are concavely curved like this.
These wires 24 extend between the mutually opposite side frame parts 4, 5 of the tubular frame 3. Both ends 26 of the wires 24 are bent downwards at right angles and fastened to the mutually facing inner sides of the side frame parts 4, 5.
These wire ends 26 in turn only extend over a little more than half the diameter of the side frame parts 4, 5, so that they do not protrude beyond them. Therefore, these wire ends 26 do not have to be separated in a separate operation.
the wires 24 are at the top of the frame parts 4, 5, so that no step is formed at the transition from the frame parts to the wire mesh.
the wires 17 of the back surface 16 are, as shown in FIG. 6, at the level of the front of the side frame parts 9, 10 and the upper frame part 11, so that no shoulder is formed at the transition from the back surface 16 into the frame parts 4 to 6 that would be annoying when leaning on.
the wires 25 of the seat 23 are welded to the underside of the wires 24.
Their front ends 27, as shown in FIG. 3, are 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 in turn extend only slightly over half the diameter of the frame part 6, so that these wire ends do not protrude downward over the frame part. Therefore, the wire ends 27 also do not have to be separated in a separate operation.
the side frame parts 4, 5 of the seat part 1 are connected by a cross strut 28, which is advantageously of the same design as the cross strut 12 of the back part 2.
the ends of the cross strut 28 are facing one another Fixed inside of the frame parts 4 and 5, preferably welded. 5, it is provided on its underside with a recess 29 which extends over the entire length of the cross strut 28 and into which the ends 30 of the wires 25 protrude.
the depth of the depression 29 corresponds to the thickness of the wire ends 30 which are fastened to the back surface 31 of the depression 29.
the end of the wire ends 30 advantageously lie against a bottom 32 of the depression 29 lying at right angles to the back surface 31. In the direction of the seat surface 23, the wire ends 30 are thus covered by the part 33 of the cross strut 28 which has the back surface 31, so that there is no risk that the wire ends 30 can damage the clothing.
the cross strut 28 is curved in the same way as the front frame part 6 and the wires 24.
two angle pieces 34 and 35 are fastened (FIG. 2), which are each L-shaped.
a cross strut 38 is attached, through which the seat part 1 is sufficiently stiffened.
the legs 36, 37 each have at least one opening 39, 40 through which screws, threaded bolts and the like can be inserted in order to detachably with the angle pieces 34, 35 about the cross strut 38 which rests with its ends on the legs 36, 37 to be able to connect.
bow-shaped clamping tabs 43 and 44 can be used, which overlap the ends of the cross strut 38 and are fastened to the legs 36, 37.
the legs 41, 42 of the angle pieces 34, 35, which extend at right angles to the legs 36, 37, are fastened, preferably welded, with their end faces to the underside of the frame parts 4, 5. These upward legs 41, 42 are approximately half the width of the frame parts 4, 5, so that they do not interfere. As shown in FIG. 2, the cross strut 38 lies in the area below the front frame part 6 or the seat 23.
the seat surface 23 and the back surface 16 are bent differently, there is an optimal adaptation to the body and a high level of seating comfort. Since the tubular frames 3 and 8 are formed in one piece with one another, the overall frame 3, 8 has only a single welding point. Since the wire ends of the wire mesh forming the back surface 16 and the seat surface 23 do not rest on the tubular frame 3, 8, there are also manufacturing advantages. For example, the coating of the tubular frame can be made much thinner since the wire ends do not then have to be separated.
the wire mesh has rectangular meshes, which result in particularly high seating comfort.
the wire mesh can also have any other suitable structure.
the angle pieces 34, 35 can be designed differently depending on the type of substructure.
the seating furniture described is designed as a seat shell that can be attached to a support, a support frame or also on a wall.
