Definitions

  • the present invention relates to a spring core, with a plurality axially parallel juxtaposed, helically wound springs and one, the top or bottom laterally delimiting, circumferential, of metal, preferably steel existing frame, which is connected to adjacent springs is.
  • Such spring cores are used in many applications. especially They are used in the production of mattresses or furniture upholstery Commitment.
  • the frame of a round material preferably a round steel
  • the diameter of the round material is usually between 3.8 and 4.8 mm.
  • the spring cores usually transported from the place of manufacture to mattress production, where the respective production sites are spatially very far apart can.
  • the spring cores occupy a position of use relatively large volume with a low weight. Naturally Therefore, the transport costs of the spring cores disproportionately high, causing the Total manufacturing costs, including transport costs, adversely affected.
  • the present invention is therefore based on the object, a spring core of generic type to develop so that its handling and serviceability be improved.
  • the inventive ratio between thickness and Width of the frame reaches a high edge stability, as opposed to the stand the technique in which, as mentioned, a metal strip is used, a higher resistance moment and thus a greater bending strength is achieved.
  • a dimensioning of the frame has shown in the thickness is about 2.3 mm and the width is about 6.0 mm.
  • Also advantageous is a dimension of about 2.1 mm thick and about 6.3 mm wide, ie in the ratio 1: 3, whereby the possible deviations in the mentioned Measures in tenths of a millimeter range can move.
  • a steel with a high carbon content for example, 0.5-1.0% C is preferably selected, with a tensile strength of about 2000 N / mm 2 .
  • the modulus of elasticity of this steel is greater than that of the steel used so far, resulting in said improvement of Aufrichtmomentes.
  • the section of an innerspring is shown, which is a plurality of axially parallel having juxtaposed helically wound springs 1, which are interconnected.
  • Upper and lower sides of the spring core is each by a circumferential, made of metal existing frame 2 laterally limited, wherein the adjacent springs 1 by means Brackets 3 are attached to the frame 2.
  • the clip 3 wraps around the frame 2 and an overlying wire 4 of the Spring 1, from which it is formed.
  • the peripheral frames 2 each consist of a flat steel, whose thickness A is in the ratio 1: 2.2-3.5 to the width B, preferably in proportion 1: 2.6 or 1: 3.
  • the extension direction of the broad side of the frame 2 corresponds the top or bottom of the spring core, which is particularly clear in Figure 2 is recognizable.
  • the frame 2 can or rest on the underside of the spring 1. It is also conceivable, the frame 2 side to connect to the wire 4.
