Definitions

  • the invention relates to a two-layer floor covering in sandwich construction, consisting of a plastic underlayer and an upper layer made of synthetic high polymer fibers.
  • Elasticity - surface slidability also plays a crucial role in stressing the human musculoskeletal system.
  • High sliding friction or slip resistance blocks foot movement and thus increases the strain on the musculoskeletal system, which can lead to sprains or meniscus injuries, for example.
  • the object on which the invention is based is therefore to develop a floor covering, in particular for sports purposes, and to develop a process for its production which can be easily manufactured and economically installed and maintained while avoiding the disadvantages mentioned above.
  • a covering has been a requirement of sports doctors and, above all, athletes for years. Even so, it is not yet managed to produce an appropriate floor covering.
  • the production of the two-layer floor covering in a sandwich construction is characterized in that the two layers are connected to one another in a web shape by means of flame welding.
  • the flame welding process which is normally used for laminating, enables, in contrast to the adhesives commonly used for sandwich flooring, to achieve a durability and weather resistance that is many times higher than when using adhesives.
  • adhesives causes the textile material to harden, which severely affects the service life of the covering.
  • Laying in sheets or panels also saves a lot of work compared to the liquid introduction of materials (such as in CH patent 565 575).
  • the tread top layer 1 consists of a fleece made of synthetic propylene fibers, which has a needling 2 of at least 2 million punctures / m2. Depending on the type of sport, the needling required is between 2 million and 3.5 million punctures / m2, although for tennis courts, for example, a needling of 3 million punctures / m2 has proven to be advantageous.
  • the top layer is permeable to water, weatherproof and rot-proof.
  • This fleece 1 is now connected by means of the above-mentioned flame welding without an adhesive layer or any other intermediate layer with a closed-cell polyethylene foam 3, the air-filled d
  • the high level of surefootedness required by competitive athletes normally requires high sliding friction with the disadvantages mentioned above.
  • the covering produced according to the invention enables a high level of surefootedness, even on wet floors, but reduces the sliding friction due to the high needling of the textile surface and the damping effect of the closed-cell underlayer.
  • the air trapped in the cells of the lower layer provides very good shock absorption when the foot impacts, as is the case today only with natural underlays such as lawn or sand.
  • the musculoskeletal system is not burdened by a catapult-like recoil and is thus excessively stressed. Thanks to the absorption of the pressure by the lower layer, there is also a greatly increased resistance to abrasion of the step top layer.
  • the lower layer has a thickness of 5.5 mm, the upper layer 6 mm.
  • the lower layer preferably has a density of 30 kg / m3. Specifically, this is achieved, for example, with the Trocellen PE foam developed by Dynamit Nobel.
  • the water permeability of the surface is an absolute requirement for the use of this surface in outdoor sports facilities. Since the polyethylene foam is impermeable to water, an appropriate solution had to be found here. This consists of perforating the polyethylene foam (5), which gives it water permeability. Very good results were achieved with a hole diameter of 4 to 5 mm and a hole spacing of 2o to 3o mm.
  • the shock-absorbing effect of the covering according to the invention in connection with the high sliding security predestine it for use in school buildings and public buildings as well as for walkways and driveways all the more as the sound and heat insulating properties are excellent.
