Definitions

  • the invention relates to a multi-layer, water-permeable tennis court surface, with a tough soft material containing, water-permeable base layer.
  • Known tennis court coverings of this type have a base layer e.g. from seepage asphalt, which lies on a gravel layer with coarse grain. Permeable drainage pipes laid in this layer of gravel discharge the rainwater that penetrates through the seepage gap into the sewage system. Although these tennis court surfaces have the advantage that they do not require maintenance, their properties for playing tennis are known to be unsatisfactory.
  • the generally known clay courts with a top layer of brick granulate have satisfactory properties for tennis, but they are particularly maintenance-intensive, so that they are often unusable due to weather conditions and cannot be used for a long time.
  • the brick granulate contains a fine grain fraction that is removed by the wind without permanent moistening.
  • the invention has for its object to find a permanent tennis court surface that does not require essential maintenance and is therefore more frequently used, but which nevertheless has the playing properties known from clay courts with regard to smoothness when running and ball behavior.
  • This object is achieved according to the invention in the case of a tennis court covering of the type mentioned at the outset by an upper layer consisting of granular rock on the base layer Granules formed, so that part of these granules is mechanically bound in the tough soft material of the base layer.
  • the advantageous properties of asphalt coverings are combined with those of sand coverings without accepting their disadvantages.
  • the base layer ensures the shape stability of the surface familiar from hard courts, while the granulate layer ensures the desired playing properties.
  • the mechanical bonding of part of the granules in the tough soft material of the base layer resulting from loading of the top layer prevents a dangerous chippings effect. To slide the tennis shoe on the upper layer, however, there is sufficient mobility.
  • the top layer consisting of granules is only from time to time in the usual way, e.g. leveling with a broom, however, the maintenance work, which is expensive to maintain a uniform surface shape, especially after periods of frost, is omitted, so that the possible usage time is considerably extended.
  • the tennis court covering according to the invention has the advantage that it does not soften and become unplayable when wet, like the usual sand or marl courts, and that it dries quickly.
  • the base layer of a tennis court covering according to the invention has a shape stability which also makes it usable for additional purposes. For example, it can also be driven on by vehicles without the wheel pressure changing the base layer. Remaining traces in the upper layer can be easily removed with a broom or other usual place-cleaning device.
  • the production of the tennis court surface is relatively inexpensive. If you already have a tennis court covering made of seepage Asphalt is available, so the production is particularly simple, since only the granulate for the upper layer has to be applied.
  • the quality of the rock material to be used for the granulate of the top layer is to be selected both with regard to the desired color effect and with regard to the rock structure, so that its angularity allows it to press well into the tough soft material and continues to dry quickly after moistening.
  • a sloping rock that has been processed by breaking or grinding to a grain size range without dust is particularly suitable.
  • the preferred grain size range is 0.7 to 1.5 mm.
  • a preferred green color for tennis court surfaces results, for example, from the use of an orthogneiss from the Swiss town of Andeer known as ANDEER chippings.
  • any other material with comparable properties for the stated purpose is suitable as a tough soft material, i.e. together with the granulate ensuring the water permeability of the base layer, it should form a sufficiently strong and elastic base layer and, in addition, it should give the granules of the top layer that come into contact with the base layer a firm anchor after they have pressed in.
  • Such properties also have various synthetic resins. The selection is essentially determined by the material costs.
  • the drawing shows a simplified, stepwise cut, perspective partial view of an embodiment of a tennis court covering according to the invention.
  • the substructure layer 1 of the tennis court covering 2 has, for example, a thickness of 300 mm and consists of coarsely broken stone with, for example, a grain size in the range from 30 to 50 mm, as is used for street construction as street gravel. That from the surface 3 of the tennis surface to the bottom Building layer 1 infiltrating rainwater is derived from it via porous or perforated seepage pipes 4.
  • the sub-layer 1 is covered by a 60 mm thick base layer 5 of seepage asphalt.
  • the seepage asphalt consists of a mixture between bitumen and rock material with a grain size of 15 mm, for example.
  • the bitumen creates a tough connection between the grains without completely closing the interspaces of the fill, so that the base layer 5 has sufficient form stability from local loads on the tennis court surface 2.
  • the bitumen enables a bond with the granules of the upper layer 6 even when cooled, as a tough soft material, by pressing and wedging them into the bitumen under load. A particularly angular structure of the granules of the upper layer 6 facilitates this process.
  • the seepage asphalt can also be mixed with rubber granulate to give the tennis court surface greater elasticity.
  • the sub-layer 1 with the overlying base layer 5 made of seepage asphalt can be produced in the manner generally used for the production of asphalt tennis courts, so that the top layer 6 can also be easily sprinkled onto existing tennis court coverings of this type.
  • ANDEER chippings with a grain size range of 0.75 to 1.5 mm have proven particularly suitable for the upper layer 6.
  • the thickness of the top layer 6 can be selected in the range from 2 to 4 mm.
  • the line-shaped markings 7 required for playing tennis or for other sports can be painted directly onto the base layer 6.
  • green ANDEER split the usual yellow color is particularly suitable for road markings.
