Definitions

  • the invention relates to a method for fixing and tensioning upholstery material to an object, a recess_ being provided in the object, whereby a strip of more rigid material is attached to the free edge of the upholstery material which is cut off to measure, and that thereupon the strip with a portion projecting therefrom is fixed into the recess while exerting tensioning forces on the upholstery material.
  • a similar method for fixing and tensioning upholstery material to an object is known from CH-A-526,289.
  • the free edge of the upholstery material is provided with a strengthening strip of material that is more rigid than the upholstery material.
  • the thus thickened edge of the upholstery material is pushed into a longitudinal groove of a profiled bar, the profile angle of which is less than 90°.
  • the longitudinal groove in the profiled bar is, however, adapted for only one combined thickness of upholstery material and strengthening strip, so that with a different thickness of upholstery material also a different groove width will be necessary, which means a new strengthening strip and a new profiled bar. Because of the fact that the strengthening strip lies in a plane parallel to the free edge of the upholstery material, it is difficult to insert the strip and the free edge together into the longitudinal groove and to maintain at the same time an even tensioning in the upholstery material.
  • the invention aims at removing the above described disadvantages of the known method.
  • a profile with a T- or L-shaped section is applied as the strip of more rigid material, the body of which is pressed into the recess under exertion of frictional forces and that the free edge of the upholstery material is stitched to the flag of the profile.
  • the profile is adapted for all thicknesses of upholstery material to be used, whereas the profile with the aid of the flag, which is generally perpendicular to the body, may be easily inserted by hand into the longitudinal recess in the object, during which insertion the even tensioning of the upholstery material may be properly maintained.
  • the present invention also relates to a device for fixing and tensioning upholstery material to an object, which device is provided with a tensioning element and with which a recess for fixing and tensioning of the upholstery material is applied, whereby the tensioning element is attached over the entire length of the free edge of the upholstery material to be fixed.
  • the tensioning element of this device is a profiled bar, the profile angle of which is smaller than 90°.
  • the profiled bar is provided with an insertion portion or body, which is a simple plain lip with a rectangular section. With such a tensioning element it is necessary that the body includes a sharp angle with the direction in which the upholstery material extends from the tensioning element, so that the tension in the material tends to push the body into the recess.
  • the device according to the invention is characterized in that the tensioning element is provided with a portion projecting at an angle therefrom, which is resiliently deformably clamped in the recess which is made directly into the object.
  • the body of the tensioning element is held firmly in the recess by means of resilient deformation, without any special shape of the tensioning element itself.
  • the tensioning element comprises a T-section of flexible synthetic material, the flag of which is stitched to the free edge of the upholstery material and the body of which, which can be clamped in the recess, is provided on at least one side with at least one barb-shaped member extending in longitudinal direction, which is inclined in opposition direction with respect to the inserting direction and the greatest thickness of the body being greater than the width of the groove-shaped recess.
  • This embodiment of the tensioning element entails an easy and quick fixing and tensioning of the upholstery material, which can easily be carried out by laymen, so that a thorough washing of the upholstery between times and replacement by new upholstery could be done by laymen without any difficulty.
  • the free edge of the upholstery material is stitched to the flag on that side of the body of the T-section, which is turned away from the direction in which the upholstery material extends from the T-section.
  • the section is covered by the upholstery material and by this method of fixing of the upholstery material it is also reached, that the tensioning force of the upholstery material on the stitching seam on the T-section is at least partly taken up by the flag of the T-section.
  • the invention finally also relates to a pre-fabricated upholstery cover for objects, especially chairs and the like.
  • the pre-fabricated upholstery cover according to the invention is characterized in that over the entire length of the free edge of the upholstery cover to be fixed, a tensioning element is attached, a portion of which projects at an angle from the portion attached to the upholstery cover.
  • the tensioning element of the upholstery cover is a T-section, the flag of which on one side is attached to the free edge of the upholstery material and the body of which is provided on at least one side with at least one longitudinally extending barb-shaped member, which is inclined in opposite direction away from the free edge of the body.
  • the method and device according to the invention as well as the pre-fabricated upholstery cover can especially be applied to seat furniture, provided with a trunk or frame, preferably made of wood, as into this material a groove-shaped recess can be easily milled, but the trunk may also be made of synthetic material or metal or another natural or synthetic material, into which the groove is milled then, molded in the injection mold or achieved in another way.
  • the method and device according to the invention as well as the pre-fabricated upholstery cover can, of course, also be applied to other objects, e.g. tables, car- and airplane chairs and benches, which must be provided with an upholstery.
  • the frame or the trunk of seat furniture or other objects, provided with an upholstery cover is usually provided with foam-rubber sheets or sheets made of synthetic foam material and stuffing pieces, over which the upholstery is tensioned, this is not absolutely necessary; if a relatively thick upholstery material is used, this could be sufficient in some cases.
  • the bench or arm-chair 1, drawn in figure 1 is provided with a frame or trunk 2, comprising two side panels 3 which are tightly connected to each other by longitudinal or cross beams 4, 5 and 6, such that a non-deformable frame is obtained.
  • a frame or trunk 2 comprising two side panels 3 which are tightly connected to each other by longitudinal or cross beams 4, 5 and 6, such that a non-deformable frame is obtained.
  • extra stiffening and/or support beams or support sheets could still be applied for instance to support the foam-rubber or synthetic foam rubber back and seat cushions 7 and 8, which are supported by webs (not shown), tensioned in transverse and longitudinal direction between the side panels 3 and between the stiffening and support beams.
  • a foam rubber or synthetic foam rubber sheet 9 can still be applied to cover the frame on that side too, while also the beams 6 and the side panels 3 on the outer side can be provided with such a sheet 10.
  • the upholstery cover 11 could comprise one piece of leather, synthetic material, textile or other material, cut off on moulds to the right measure and stitched at the necessary places to bring the cover into the right shape.
  • a T-section 13 made of synthetic material, is stitched over the entire length of the peripheral hem or free edge 12.
  • the T-section 13 is provided with a flag 14 and a body 15.
  • the peripheral hem or free edge 12 of the upholstery cover 11 is stitched to the flag 14 of the T-section along a seam 16 on that side of the body 15 which is turned away from the direction in which the upholstery material 11 extends from the T-section 13, as appears from figure 2.
  • the advantage thereof is, that on one side the T-section 13 is covered by the material 11, and on the other side, which is still more important, that at least a part of the tensioning force of the upholstery cover 11 is absorbed by the flag 14 itself and therefore this tensioning force never has to be absorbed entirely by the stitching seam 16.
  • the body 15 of the T-section 13 has a firtree- shaped cross-section, barb-shaped members or ribs 17 being formed, the operation and function of which will be further elucidated in the foIIowing. ⁇
  • the T-section 13 is applied along the entire periphery of the free edge hem 12 of the cover 11, thus along the lower side of the frame beams 4 and 6 as well as along the lower side of both side panels 3 and moreover along the lower side of the frame beam 5, in order to be able to tension the front back flap 7' and the seat flap 8' and to fix them. Therefore, the front back flap 7' and the seat flap 8' of the cover 11 are stitched on their free edges to a tensioning strip 11', the free edge of which in its turn is provided with a T-section 13 of synthetic material in the above described way, which can be pressed with its body 15 into a recess in the lower face of the frame beam 5 in the way as described in the following.
  • a groove 18 is milled into the lower face of the frame beam 4 over the entire length, the width of which is smaller than the greatest thickness of the body 15 of the T-section 13, including the barb shaped hooks 17, at least one of which is applied to one side of the body 15.
  • the cover 11 is tensioned by smoothing it by hand downwards over the rear back panel, the V-shaped free edge of the body 13 being positioned in front of the entrance of the groove 18. If the upholstery cover is sufficiently tensioned, the T-section is manually pressed with the body 15 into the groove against the frictional force. The body of the T-section 13 is sufficiently tightly fixed in the groove 18 in this way, because if for instance someone pulls at the upholstery material in the direction of the arrow 19 in figure 2, no or at the most only relatively small force is exerted in outward direction on the body 15 of the T-section' 13. The barbed hook-shaped ribs 17 bite as it were into the wood of the groove walls.
  • the invention is not restricted to the above described application of the T-section 13. Instead of that, also an L-shaped section in the shape of angle steel could be applied.
  • the "body" of the T- or L-section can be smooth and can be fixed in the groove 18 with or without the aid of a non-setting adhesive. If a slightly resilient and/or flexible synthetic material is used for the fixing section, the thickness of the "body” of the section, which must be positioned into the groove 18, can in this case also be equal to or somewhat greater than the width of that groove 18.
  • the free edge or hem 12 of the upholstery cover 11 can also be stitched to the flag on the other side of the body of the T-section or another section or for instance be attached with an adhesive if this is preferred for some reason or another or if one is obliged to do so under certain circumstances.
