Definitions

  • the invention relates to a spring core according to the preamble of claim 1.
  • Spring cores are used in different areas. Examples of spring cores for upholstered furniture, but especially for mattresses called.
  • the individual springs are made of wire, usually metal wire, which is helically wound.
  • Bonnell spring cores a plurality of springs are joined together in a row and connected to one another by helically wound wires which engage in end rings of the individual springs.
  • the invention has for its object to further develop a spring core of the generic type so that it is easier and cheaper to produce and different spring characteristics are easily adjustable. This object is achieved by a spring core with the features of claim 1.
  • Such a spring core can be varied without changing the spatial shape of the individual springs in its suspension behavior, as needed, wherein not only one spring core can be produced substantially without additional effort, which is different from another, but also spring cores with partially different suspension behavior.
  • Starting product are quasi identical individual springs, in which, in order to adjust the different suspension behavior, only a rotation of the individual springs, preferably made of a plurality of springs series. This leads to a change in the characteristic, since the shaped notch then occupies a different position.
  • This notch is formed by two legs which enclose an angle ⁇ 90 °.
  • the tip of the notch protrudes beyond the center of the formed ring.
  • the length of the lever arm formed by the legs and thus the load acting moment changes or the spring characteristic changes accordingly.
  • a plurality of parallel and spaced apart springs are connected by preferably two connecting elements in such a way that a permanently accurate position is ensured to each other.
  • the connecting elements in particular in the form of rods can be positively attached to the springs.
  • the connecting elements in principle, however, is also an integral connection such as gluing welding or soldering.
  • this compound is less suitable for a series product, since it can only be produced with a relatively high outlay.
  • the springs of a row can be congruent to each other, ie, the notches of all springs are aligned so that the spring characteristic is changed altogether by turning the series.
  • this extension usually determining the width of the spring core.
  • other rows as mentioned, are twisted to change the spring characteristic.
  • all rows are attached to the end of a frame enclosing the spring core, for which purpose said rods can be used.
  • Figure 1 shows a spring core according to the invention in a perspective
  • Figure 2 shows a part of the spring core, also shown in perspective, Figure 3 shows an enlarged section of the illustration of Figure 2
  • FIG. 1 shows a spring core is shown, with a plurality of mutually parallel rows of springs 1, each of which consists of several interconnected individual springs 3, wherein the rows of springs 1 are each held on top of a peripheral frame 2.
  • Each spring 3 is designed as a ring arranged upright in the direction of loading, consisting of an elastically deformable wire, with a notch 4 pointing in the contour progression.
  • the springs 3 are a spring row 1 , which are arranged parallel and distant from each other, by a rod 5, preferably also made of wire, connected to each other, for which purpose the wire of the spring 3 is looped in the sense of a node 6.
  • each node 6 is arranged in a recess of the spring 3, so that the rod 5 rests sunk.
  • rods 5 are provided on two mutually opposite sides, so that spring row 1 results in a stable construct.
  • the notch 4 is formed by two acute angles to each other legs 7, the apex of which lies outside the center of the circular arc-shaped spring 3 and that goes beyond this.
  • FIGS. 4b) and 4c) show springs 3 twisted around the imaginary central axis, with the resulting positions of the notches 4 and, with respect to the load B, a lever with a smaller action due to the position of the legs 7, FIG. 4c) reproduces the position in which the springs 3 have the greatest hardness.
  • the springs 3 are arranged so that they engage in the spaces formed between the individual springs 3 of the adjacent spring rows 1, so that there is a relatively closed bearing surface.

Abstract

L'invention concerne un bloc-ressort, comprenant une pluralité de rangées de ressorts (1) agencées parallèlement les unes aux autres, chacune de ces rangées étant constituée d'une pluralité de ressorts individuels (3), raccordés les uns aux autres, ce bloc-ressort étant conçu de sorte que chaque ressort (3) se présente sous la forme d'un élément annulaire disposé sur la tranche dans le sens de sollicitation et constitué d'un fil métallique déformable élastiquement, comportant une encoche (4) orientée vers l'intérieur sur son contour.
