Definitions

  • the invention relates to a sports device in which a support is supported against a support via a spring block made of an elastically compressible material, which is elastically compressible and can be elastically subjected to thrust and is in a corresponding operative connection with the support and the support via support surfaces.
  • a known (DE-A 2832074) sports device of this type is a so-called gymnastics floor covering, the bottom layer of which is formed by spring blocks distributed over the surface and spaced apart from one another, the base forming the base for the spring blocks.
  • the spring blocks are either elongated like bars or cuboid, but in any case full, i.e. Consistently formed over its entire vertical and horizontal cross-section by the elastic material, which is a plastic foam.
  • the horizontal cross section is always the same from top to bottom, which is associated with a relatively poor spring characteristic in that the spring force does not change to the desired extent with the increase in the compression of the spring block. It has therefore also been considered to give the spring blocks a horizontal cross section which decreases towards the top in order to achieve the desired progressive spring characteristic.
  • this pyramid-like spring block if dimensioned with a view to a certain spring travel and a certain softness, tends to buckle to the side.
  • a sports device is also known (DE-A 1 578671), in which a spring block has a concavity which runs parallel to the base and a wall surrounding it with two side wall parts each bent outwards. Due to its material, this spring block is inherently rigid and cannot be subjected to thrust, has a thin wall in the middle between the two support surfaces and has poor spring characteristics.
  • spring block with continuous cavity only one of the two support surfaces is widened on both sides by a protruding ledge and full side wall parts are only subjected to compression when loaded. Since this spring block essentially only works through compression, it has a poor spring characteristic.
  • the sports device according to the invention is solving this problem, characterized in that the spring block has a concavity parallel to the base and a wall surrounding it with two side wall parts each bent outwards, that the two support surfaces resting on the support or base have on both sides are each widened by a projecting ledge and that the ratio between the outer diameter of the spring block and the inner diameter of the cavity is at least 1.5 in the middle between the two supporting surfaces.
  • This spring block in which the two side wall parts each bend outward when loaded, has a very favorable progressive spring characteristic and absorbs shear forces resiliently without changing the progression of the spring characteristic.
  • the two pairs of ledges further improve the fit of the spring block between support and underlay against shear stresses.
  • the broadening of the support surface achieved by the ledges is also important because the support surface tends to stand out in the middle in front of the underlay or support due to the cavity.
  • the two ledges of the support surface enlarge the edge areas which, despite lifting off, bear tightly against the support or support.
  • the ledges are particularly important when the spring block is attached to the support or underlay by gluing and, if necessary, additional stitching.
  • the cross section of the cavity is usually constant over its length; e.g. octagonal or oval. However, it is particularly expedient and advantageous if the cross-section of the cavity running transversely to the base is circular in the unloaded state. This cross-section is not only particularly favorable in terms of production technology, but also with regard to the buckling behavior of the side wall parts and better compensates for the stability against shear forces in both surface directions.
  • the thickness of the wall is greater at the center of the side wall parts than in the center of the supporting surfaces and that the thickness of the wall decreases from the center of the side wall parts to the ledges.
  • This design fulfills the purposes according to the invention particularly favorably.
  • the restoring force is improved without increasing the height or the spring travel.
  • the ratio of the outer diameter of the spring block: inner diameter of the cavity in the middle between the two support surfaces is at most 2.5, preferably at most 2.0; if the ratio between the outer diameter of the spring block and the inner diameter of the cavity is up to 2, preferably approximately 1.5, between the two ledges of a support surface; and / or if the maximum width of the spring block transverse to the axial direction is greater than its height.
  • the thickness of the spring block in the axial direction of the cavity differs depending on the intended use or type of sports equipment and on the properties otherwise desired. However, it is particularly expedient and advantageous if the thickness of the spring block in the axial direction of the cavity is smaller than the width and / or the height of the spring block transverse to the axial direction of the cavity. This dimensioning is advantageous with regard to the desired spring characteristic, and in particular together with the other preferred embodiments.
  • the spring block according to the invention is provided on a springboard (DE-B 2725401), specifically on one or more of the support areas which are formed by the support board and spring leaf, spring leaf and headboard, and headboard and support board.
  • the spring block is pushed between the two boards or the board and the sheet, either only a long spring block or preferably a row of narrow spring blocks being provided.
  • the material of the spring block is e.g. Foam rubber. However, it is particularly expedient and advantageous if the material of the spring block is a plastic, namely a cellular polyurethane elastomer.
  • This material selected according to the invention has a high restoring force, which is what is the case with sports equipment, e.g. Swinging floors, is important and is only poorly guaranteed if the spring block is configured in the manner described above with regard to other spring properties.
  • the material selected according to the invention is particularly useful in connection with the design according to the invention.
  • the rebound force of the polyurethane material used here is 100% greater than that of foam rubber.
  • the compressibility is approximately 100% greater for foam rubber than for the polyurethane material.
  • 1 and 2 consists of a cellular polyurethane elastomer, which is a slightly foamed product with a density of 200 to 650 kg / m 3 . It results from the reaction of polyhydroxyl components (polyester or polyether) with diisocyanates and subsequent reaction with a "crosslinker".
  • polyhydroxyl components poly(polyester or polyether)
  • diisocyanates diisocyanates
  • crosslinker a polyhydroxyl components
  • Such elastomers are based, for. B. based on polyester polyols and 1,5-naphthylene diisocyanate (NDI). You will e.g. B. described in the special print from ATZ, automotive technical magazine, 80th year, No. 2/1978 Frankhsche publishing house Stuttgart.
  • the spring block In the relaxed state, the spring block has an upper support surface 1 and a lower support surface 2, both of which are flat and rectangular.
  • the spring block is essentially a tubular structure that has two ledges 3 at the top and bottom, which extend over the thickness of the spring block and partially form the support surfaces.
  • a side wall part 4 of the wall extends between an upper ledge 3 and an underlying ledge, which surrounds a cavity 5 which is circular in cross section.
  • Each of the two side wall parts 4 is bent outwards and has a thickness approximately in the center, seen in the radial direction, which is greater than the thickness of the wall in the center of the support surfaces 1, 2.
  • spring blocks 6 are part of a floor gymnastics plate, which has a base 7 below, which is formed by a plywood plate, on the edge of which a hooking plate 8 is riveted.
  • the floor gymnastics plate has a top 9, which is formed by two plywood plates glued to each other, each of which is reinforced by a glued glass fiber fabric.
  • the spring blocks 6 are located under the support 9.
  • FIG. 4 illustrates the distribution and arrangement of the spring blocks 6 provided in a large number per gymnastics plate Spring blocks are arranged at a distance from each other that is far larger than each of their outer dimensions.
  • spring blocks 6 according to FIGS. 1 and 2 are provided on a springboard, in which a headboard forms a support 9 and an S-shaped spring leaf forms a base 7.
  • the diving board also has a support board 10 at the bottom.
  • the spring blocks here are each longer than high or wide and are all in the same direction, the distance between two adjacent spring blocks being smaller than one of the outer dimensions of the individual spring block .
  • the front end of the headboard and spring leaf is held together by a cross-sectionally U-shaped enclosure 11.
