Definitions

  • Mattresses and cushions of the innerspring type have achieved widespread use because of their excellent characteristics of softness, lack of permanent deformation in use, and the like.
  • it is attempted to lock the innerspring coils at both top and bottom in order to minimize sideways movement, produce firm edges, and the like.
  • Firm attachment is made to a bottom frame, which may be of metal, for example metal strips, and the top of each coil is locked to its adjacent one by cross strips, wire fastenings and the like.
  • the present invention obviates the drawbacks of earlier constructions, some of which have been set out above, by providing the sideways locking of the individual coils at one or more points near their centers and, if desired, particularly in the case of cushions, the bottom of each coil is locked against sideways movement.
  • the tops of the coils are not locked sideways and the cover is an elastic fabric which can stretch.
  • the fabric need not be capable of a great percentage elongation because the total stretch is over the whole length or width of a fabric and even if it stretches only a moderate percentage, for example 20% to 30%, there is substantially no sideways pull on the top of each of the coil springs. So when a weight is applied, only the springs underneath the weight are compressed.
  • the adjacent springs are not pulled sideweys; there is formed no valley, and since there is no rigid or semi-rigid locking of the tops of the springs coils, they can be made much softer, which is desirable in many cases.
  • the wire in the coils may be of sufficiently heavy gauge to produce this effect, but it is not arbitrarily increased by sideways locking, either by metal ice connections or by relatively inextensible textiles. Much more comfortable mattresses and cushions are thus produced with no tendencies to form valleys and with a definite and accurately predetermined resilience which is not arbitrarily decreased by sidewayslocking.
  • FIG. 1 illustrates a mattress or cushion of conventional design in cross section
  • FIG. 2 is a similar section through a cushion structure of the present invention.
  • FIG. 1 illustrates a common modification in which springs are attached to metal bottom strips 1, coils are shown at 2 and 4, with sideways metallic connections at 3.
  • a cover of inextensible textile material is shown at 6 in FIG. 1, and a similar cover of elastic material at 7 in FIG. 2.
  • Loads 5 are shown in both figures, which may be a person lying on a mattress or seated on a cushion. It will be noted that in each case the coils 4 directly under the load are compressed in the usual manner with coil spring cushion structures, and the inextensible cover 6 pulls adjacent coils 2 sideways toward the load, thus producing a valley.
  • FIG. 2 it will be seen that while the coils 4 underneath the load are compressed as before, the elastic cover 7 stretches and there is no sideways pull, so that the adjacent coils 2 are not depressed and no valley is formed.
  • the tops of the coils are shown without separate sideways locking structure in FIG. 1, although it is customary in coil spring cushion structures in the past to provide locking at the top either with metallic fastenings or by rigid attachment into the cover.
  • the present invention involves a combination of an elastic cover and coils which have no sideways locking at their top.
  • the particular nature of the elastic material for the cover forms no part of the present invention so long as it has suflicient stretch in the desired directions.
  • Fabrics having covered elastic warp and/ or weft threads may be used or textile fabrics which are capable of stretching may be used in which the individual threads may not stretch or may stretch considerably less than is the case with the normal elastic thread.
  • a coil spring cushion structure comprising a plurality of spring coils, means spaced from at least one end 3 thereof for sideways locking of the coils to prevent iturning or cocking in use, and a covering fabric for at least one side of elastic material capable of stretching in at least one direction, the fabric being unattached to the spring coils and capable of sliding across the ends thereof, whereby under load only the coils under the load are compressed and adjacent coils are not pulled sideways in the stretch direction.
  • a coil spring cushion structure according to claim 1 in which one end of each coil is attached to a structure 4.
  • a coil spring cushion structure according to claim 2 in which one end of each coil is attached to a structure which is inextensible sideways and the other ends of the coils are free.
