Definitions

  • This invention relates to spring interiors for mattresses and other articles such as divans, seats, chairs, settees and the like, the articles including components such as seat squabs and seat backs.
  • a known form of spring interior comprises a plurality of bands of springs disposed side by side and connected together by helical wires which extend transversely of the bands and embrace portions of the bands.
  • bands of springs have been proposed for incorporation in spring interiors.
  • band of springs of the kind specified comprises a single length of spring wire shaped to form a plurality of individual coil springs arranged in a row, one end turn of each coil spring lying adjacent to a top face of the band and the other end turn of each coil spring lying adjacent to a bottom face of the band, each coil spring being of a hand opposite to the hand of the adjacent coil springs immediately before and after it in the row, and being joined to said adjacent coil springs by wire links integral with the coil springs, one of said links being in the top face of the band and the other of said links being in the bottom face of the band, and each link comprising a bridging portion which extends lengthwise of the row.
  • bands of springs of the kind specified When bands of springs of the kind specified are assembled together to form a spring interior they are disposed side by side and interconnected by helical wires, some of which lie in the top face of the spring interior and others of which lie in the bottom face thereof, the top and bottom faces of the spring interior being the faces defined by the top and bottom faces of the bands incorporated in the spring interior.
  • Each helical wire extends across the bands of springs and embraces portions of wires of the bands that extend transversely of the bands from the ends of the bridging portions of the links.
  • the helical wires are disposed at uniform intervals along the bands of springs, the arrangement being such that there are two springs disposed in the interval between each helical wire and the next. There is a similar arrangement in the bottom face of the spring interior.
  • the top face of a spring interior assembled in this way has the general appearance of a rectangular grid.
  • Each of the transverse elements of the grid comprises a helical wire, and each of the longitudinal elements of the grid comprises a row of mutually aligned bridging portions.
  • Within the confines of each rectangle of the grid and disposed a little lower than the grid are the upper end portions of two adjacent coil springs, those two springs constituting parts of the same band of springs.
  • the bottom face of the spring interior is of course similar to the top face, though inverted.
  • top faces For convenience of description certain faces are referred to as top faces and others as bottom faces. It is to be understood, however, that such use of the terms top and bottom herein are not intended to introduce any limitation or restriction into the ways in which the parts or products concerned may be orientated during manufacture or assembly or when in use. It may happen, however, that in a number of instances, particularly in relation to spring interiors incorporated in mattresses, and articles such a seat squabs, the top surfaces of the spring interiors will be disposed at the top thereof.
  • a spring interior it is customary for a spring interior to be incorporated in an upholstered article.
  • at least one of the main faces of the spring interior (that is the top and bottom faces. thereof) is covered by a layer or layers of padding.
  • This in turn may be covered by a cover made of sheet material such as ticking, upholstery fabric, leather or the like.
  • a cover made of sheet material such as ticking, upholstery fabric, leather or the like.
  • the filling is pressed towards the spring interior, and in the absence of any additional support tends to enter the rectangular openings in the grid.
  • the thickness of the filling is relatively small as compared with the dimensions of each rectangular grid opening the upholstery tends to be deformed in such a way that the pattern of the grid forms relatively unyielding ridges in the cover and can be felt by the user.
  • This entry of the filling into the spring interior is a typical example of a phenomenon known in the trade as "cupping".
  • the diaphragm or separator may comprise a sheet of flexible but inextensible fabric or it may comprise a sheet of mesh.
  • One type of mesh that is widely used comprises a plurality of uniformly spaced parallel cords of twisted paper or plastics strip traversed at right angles by a plurality of uniformly spaced parallel resilient wires, the wires piercing all the cords except the two marginal cords, and end portions of the wires being shaped to form tight loops or eyes embracing the marginal cords.
  • the rectangular apertures in such a mesh are considerably smaller than those in the grids of the top and bottom faces of the spring interior so that any tendency to "cupping" is much reduced.
  • An object of the present invention is to provide an improved construction of band of springs which, when incorporated in a spring interior, reduces the problem outlined above.
  • the present invention consists in a band of springs of the kind specified in which the bridging portions of links in the top face of the band, or in the bottom face of the band, or in both the top and bottom faces of the band, are so shaped as to extend not only longitudinally of the band but also laterally thereof, so that at locations along the band between the ends of those bridging portions intermediate parts of the bridging portions afford supporting structures such as may be used to support upholstery.
  • padding or other upholstery material is disposed against a face containing those supporting structures there is a reduction in any tendency there might be for it to enter the band through that face when forces are applied to the material in a direction or directions such as to compress the coil springs incorporated in the band.
  • the present invention consists in a spring interior comprising a plurality of bands of springs, at least some of which are in accordance with that aspect of the present invention set out in the last preceding paragraph but one, disposed side by side and interconnected by helical wires lying in the top and bottom faces of the bands and extending across the bands, each helical wire embracing portions of wires of the bands that extend transversely of the bands from the ends of the bridging portions of the links.
  • the present invention consists in an upholstered article comprising a spring interior in accordance with that aspect of the present invention set out in the last preceding paragraph, and including upholstery material disposed against at least one of the main faces of the spring interior (the main faces being those containing the top and bottom faces of the constituent bands), in which the bridging portions of the links afford said supporting structures.
  • all the bridging portions in the top face, or all the bridging portions in the bottom face, or all the bridging portions in both the top and bottom faces of the band are shaped to afford supporting structures.
  • Each supporting structure may be of any of a wide variety of different shapes. It is of couse desirable that the supporting structure should provide adequate support without requiring the use of more spring wire than is necessary and that the support should be afforded in a suitable position or positions. As far as this latter consideration is concerned it is often desirable to provide a supporting structure half way between the ends of the bridging portion of which it forms a part so that in a spring interior it lies half way between adjacent helical wires.
  • the supporting structure may be disposed substantially symmetrically with respect to the longitudinal centre line of the top or bottom face of the band of springs of which it forms a part; preferably it extends more than half way across the top or bottom face of the band, and more preferably for at least three quarters of the way across the band.
  • the supporting structure may be in the shape of a semi-circle or other arc or it may comprise a pair of straight portions inclined to each other. Alternatively it may be of sinuous or zig-zag form; for example it may be shaped to resemble the letter W.
  • a preferred form of supporting structure is in the shape of a loop or loops of wire lying in the top or bottom face of the band and extending to one side of the remainder of the bridging portion of which the loop or each loop forms a part. It is generally appropriate to provide just one loop in each bridging structure.
  • the support means comprising loops formed by shaping means that is also used to form the coil springs.
  • the number of loops of one hand in any extensive length of the band is preferably balanced by the number of loops of the other hand in that length of band.
  • each loop of one hand succeeds a loop of the other hand, though a coil spring or coil springs may be formed between such successive loops.
  • the bridging portion of every link is formed with a single loop, and each loop of one hand is succeeded by a loop of the other hand so that all the loops in the top face of the band are of one hand while all the loops in the bottom face of the band are of the other hand.
  • the band of springs is made from a single length of spring wire shaped to form a plurality of individual coil springs 1 arranged in a row.
  • Each coil spring 1 comprises about two and a half turns of wire.
  • the axis of each coil spring is not upright but is inclined lengthwise of the band, each spring being inclined in a direction opposite to that in which its two immediate neighbours in the row are inclined.
  • the end turns of the coil springs 1 lie adjacent to the top and bottom faces of the band.
  • Each coil spring, such as that numbered 2 is so coiled as to have a hand opposite to the hand of the adjacent coil springs, such as 3 and 4, immediately before and after it in the row.
  • Each coil spring 1 is joined to the next adjacent coil springs by wire links integral with the coil springs.
  • One of the two links is in the top face of the band and the other is in the bottom face thereof.
  • coil spring 2 is connected to coil spring 3 by link 5, which is in the top face of the band, and to coil spring 4 by link 6, which is in the bottom face of the band.
  • Each link comprises a bridging portion 7 which extends longitudinally of the row of coil springs.
  • Each link also includes end portions 8 each of which extends in a direction normal to the longitudinal axis of the band. Those end portions 8 of the links also lie in the top and bottom faces of the band.
  • Each bridging portion 7, in addition to extending longitudinally of the band also extends laterally thereof to form a supporting structure in the form of a loop of wire 9 lying in the top or bottom face of the band, as the case may be, and extending to one side of the remainder of the bridging portion of which it forms a part.
  • Each loop 9 lies half way between the end portions 8 of the link of which it forms a part and it extends from one side face of the band to a location a little way short of the other side face thereof, though rather more than three quarters of the way across the band.
  • Each loop 9 includes a semicircular central part 10 which joins parallel, rectilinear limbs 11 parallel with the end portions 8. It will be observed that all of the loops 9 in the top face of the band are of one hand while all the loops in the bottom face of the band are of the other hand.
  • the band of springs illustrated in Figure 1 can be made by a method similar to that described and illustrated in the complete specification of British patent No. 937 644 of Willi Gerstorfer, and using apparatus similar to that described and illustrated in that specification.
  • the operation of that apparatus can readily be modified to produce a loop-shaped supporting structure of the same hand as the coil spring just formed or of the same hand as the coil spring about to be formed.
  • each coil spring is coupled with the next by having an intermediate turn thereof passed round an intermediate turn of the next spring. This coupling can be carried out mechanically by a method similar to that described in the aforementioned complete specification.
  • the coil springs 1 illustrated in Figure 1 are coupled in this manner.
  • the band of springs can be wound up to form a roll in the manner described and illustrated in the aforementioned complete specification.
  • the support structures 9 do not project out of the planes of the top and bottom faces of the band of spring they do not interfere with the packing of the turns of the roll that occurs as it is wound up.
  • FIG. 2 illustrates a modification that can be incorporated in a band of springs generally similar to that shown in Figure 1.
  • each link 5 is replaced by a link 12 of the shape illustrated in Figure 2.
  • Each link 12 has a bridging portion 13 which extends longitudinally of the row of coil springs.
  • Each link 12 also includes end portions 14 similar to the end portions 8 of the links 5.
  • the bridging portion 13 is formed with a supporting structure 17 of zig-zag form shaped to resemble the letter W. This extends more than half way across the face of the band in which it lies.
  • a plurality of bands of springs can be assembled to form a spring interior.
  • Figure 3 shows part of such a spring interior.
  • Bands of springs, 15, each similar to that shown in Figure 1, are disposed side by side and preformed helical wires 16 are attached to them.
  • the helical wires 16 lie in the top and bottom faces of the bands and extend at right angles to the longitudinal axes of the bands.
  • Each helical wire 16 embraces one pair of closely adjacent end portions 8 of each band.
  • the assembly may be effected by a method similar to that described and illustrated in the complete specification of British patent No. 1 095 980 of Multilastic Limited.
  • each of the transverse elements of the grid comprises a helical wire 16, with the end portions 8 embraced by it, and each of the longitudinal elements of the grid comprises a row of mutually aligned bridging portions 5.
  • the upper end portions of two adjacent coil springs 1 Within the confines of each rectangle of the grid and disposed a little lower than the grid are the upper end portions of two adjacent coil springs 1.
  • the top face of the spring interior would present relatively large rectangular apertures into which upholstery material such as filling or padding placed on top of the top face could readily enter, thereby giving rise to "cupping".
  • the spring interior can be incorporated in an article such as an upholstered mattress or a seat squab.
  • One or more layers of filling or padding are placed against the top and/or bottom face of the spring interior and covered with a suitable cover material.
  • the support structures tend to resist "cupping" of the filling or padding.
