Definitions

  • the invention relates to a sports floor, in particular for gymnastics and multi-purpose halls, with mutually spaced resilient elements for supporting a load distribution layer formed by panels or the like made of wood or similar material on an underbody.
  • a sports floor of the type mentioned is known from DE 38 38 733 A1. With this sports floor, a reduction in the deflection of the load distribution layer is advantageously achieved.
  • the invention is based on the object to improve the sports floor of the type mentioned in such a way that it shows a higher response.
  • the invention provides a sports floor in which the grooves or saw cuts made in the load distribution layer create a high response behavior in that the mass of the individual areas impacted by impacts or the like is reduced. Decoupling of adjacent areas is achieved by means of the grooves or saw cuts, and consequently a reduction in the load, based on a point or a surface of the sports floor that is subjected to an acting force.
  • the sports floor has a load distribution layer, on the underside of which, in the area of the grooves, resilient elements which are adapted in profile are inserted.
  • the height of the resilient elements is selected such that a predetermined distance between the load distribution layer and the underbody is maintained in the unloaded state of the sports floor.
  • the resilient elements which are made of an elastic material, compress, the deflection of the load distribution layer being limited when the load distribution layer comes to rest on the sub-floor.
  • the grooves or saw cuts which are made in a grid-like structure from the underside of the load distribution layer, preferably run centrally above the resilient elements.
  • an elastic mat is additionally provided between the resilient elements, which is attached to the load distribution layer, for example glued on, and maintains a predetermined distance from the underbody in the unloaded state of the sports floor as well as the resilient elements.
  • the resilient elements are fastened, for example glued, to the lower surface of the load distribution layer, that is to say they are placed directly on the lower surface of the load distribution layer in the region of the lattice-shaped grooves which are designed as saw cuts.
  • an elastic mat attached to the lower surface of the load distribution layer and having the same height as the resilient elements can be provided.
  • the vibrating floor according to the invention has surface elastic properties and a very uniform and relatively small deformation trough.
  • the elasticity of the vibrating floor responds quickly even at low loads, for example when exposed to children.
  • the elasticity curve is markedly progressive, which means that it decreases rapidly as the load increases.
  • the response of the elasticity and the ball reflection of the vibrating floor are decisively determined by the mass of the surface, i.e. the load distribution layer together with the top covering.
  • a mass that is too high that is, a surface that is too thick, too heavy, and also too rigid, makes the resilience and thus the force reduction desired by the athlete when running and jumping insufficiently effective.
  • the loss of force is hardly or not at all effective with high-mass floors.
  • the vibrating floor according to the invention also has a high level of functional stability.
  • Wood which has many advantages, is preferably used as the load distribution layer, in particular it is a healthy material, physiologically and ecologically problem-free.
  • Figure 1 shows a first embodiment of a sports floor.
  • the sports floor consists of a load distribution layer 1, on which an upper surface is provided.
  • Grooves 6, 7, preferably in a lattice-shaped structure, are formed on the underside of the load distribution layer 1, the grooves 6, 7 being able to be provided by saw cuts in the form of saw cuts, ie grooves of comparable width.
  • Resilient elements 3, 4 are inserted into these grooves 6, 7 in a manner to be described.
  • the arrangement described above is located on an underbody designated by 14.
  • an elastic layer 26 is arranged between the downward-facing surface of the load distribution layer 1 and the surface of the underbody 14, which in the embodiment shown completely fills the space between the load distribution layer 1 and the underbody.
  • the resilient elements 3, 4 are strip-shaped or block-shaped elements, ie the resilient elements 3, 4 can completely or only partially fill the grooves 6, 7.
  • the plates 21, 22 which fix the load distribution layer 1 are provided with tongue sections 23 and groove sections 24, whereby the plates 21, 22 can be inserted into one another in the horizontal direction.
  • the elastic elements 3, 4 are inserted into the grooves 6, 7 of the carrier plate.
  • An additional mat in the form of the elastic layer 26 is arranged between the underbody 14 and the load distribution layer 1, the thickness of which is 50 as the elastic elements 3, 4 project beyond the underside of the load distribution layer or carrier plate 1.
  • the elasticity of the layer 26 is greater than that of the resilient elements 3, 4.
  • a support block 20 is arranged below the tongue and groove connection 23, 24, the height of which corresponds to the height of the layer 26, i. H. the support blocks 20 lie in the region of the joint between adjacent plates 21, 22 below the load distribution layer 1 and support adjacent plates 21, 22.
  • the load distribution layer 1 is preferably made of plywood, chipboard or wood fiber boards, possibly also made of plastic and has a thickness of 15 mm, for example.
  • the resilient elements 3, 4 have a height such that in the embodiment shown they protrude from the lower surface 12 of the load distribution layer by a height of 5 mm. As can be seen from FIG. 1, the elements 3, 4 rest on the underbody 14.

  • the elements 3, 4 can be strip-shaped or block-shaped.
  • an elastic layer 26 is provided between the load distribution layer 1 and the underbody 14, which fills all or most of the space between the load distribution layer 1 and the underbody 14 on the side of the elements 3, 4. 2, the thickness of the layer 26 is equal to the height of the resilient elements 3, 4.
  • the elasticity of the elements 3, 4, on the other hand, is different from that of the layer 26, as described in connection with FIG. 1.
  • support blocks 20 are arranged on the joints or tongue-and-groove connections 23, 24 of the plates of the load distribution layer 1, which are arranged below the adjoining plates which form the load distribution layer 1 and have the same height like elements 3, 4 or layer 26.

  • so-called ventilated sports floors according to the invention are described below with reference to FIGS. 3 and 4.
  • FIG. 3 corresponds essentially to the embodiment of Figure 2, but with the proviso that the layer 26 has a smaller thickness than the height of the elements 3, 4, so that in the unloaded state of the sports floor, an air gap designated 27 between the upper surface of the underbody 14 and the downward facing surface of the layer 26 is set.
  • Layer 26 is e.g. B. attached by adhesive bonding to the lower surface of the load distribution layer.

  • a support block 20 can be provided below the bar 30, which has a height which is reduced by the thickness of the bar 30 compared to the height of the elastic layer 26, as a result of which the support block 20 maintains a distance from the underbody 14 in the unloaded state of the sports floor .
  • FIG. 4 shows an embodiment of a sports floor which essentially has the structure described in connection with FIG. 1, but with the difference that, analogously to the embodiment according to FIG. 3, the layer 26 maintains a distance 27 from the underbody 14 in the unloaded state of the floor.
