Definitions

  • the present invention relates to an element allowing the production of a synthetic tennis court similar to clay courts (crushed bricks) allowing more particularly the practice of outdoor tennis.
  • the invention also extends to a method of producing such terrain.
  • the invention relates in practice to the construction of permanent clay tennis courts and to the rehabilitation of old tennis courts, in particular tennis courts made of porous concrete or any other hard surface.
  • the second layer consists of a layer of limestone or a layer of equivalent material and which is provided in particular to ensure good drainage, as well as for flexibility of play.
  • a red covering layer is produced, which is generally obtained from finely pulverized crushed brick.
  • the major interest of a surface of this type is the comfort of play which protects the muscles and the joints of the player. This comfort results on the one hand from the flexibility in depth which makes it possible to absorb the vertical impact of the foot during the race and on the other hand, from the controlled slip of the tennis shoe on the surface, which prevents the blocking of the foot in its horizontal movements.
  • the water which is suspended in the intermediate layer freezes and causes the limestone / clay complex to swell.
  • the intermediate layer generally a limestone layer
  • the whole collapses, losing all cohesion and the lines of play are destroyed.
  • the surface is unusable and requires repair which can only be undertaken when the risk of freezing is eliminated. This results in several months of neutralization of the ground.
  • document EP-A-0 373 282 describes an element for the construction of permanent tennis courts of the clay type and for the rehabilitation of old tennis courts of the clay type comprising a structured textile support with an open structure. and composed of a base and fibers into which are successively loaded a first layer of sand and a second surface layer consisting of crushed brick.
  • the present invention aims to offer in particular an element suitable for both the construction of permanent clay tennis courts as well as for the rehabilitation of such tennis courts, even on a concrete support or on any hard surface, and which avoids the disadvantages notably mentioned due to frost and heavy rain.
  • the invention also aims to provide a product with the same playing comfort as traditional products.
  • the solution proposed by the invention also makes it possible in the long term to avoid the significant costs, linked to the renovation or the restoration which is necessary with conventional grounds, as regards both the support surface and the game lines.
  • the present invention relates to an element according to claim 1.
  • the height of the second crushed brick layer is between 1/5 and 1/10 of the total height of the complex comprising the two layers of sand and crushed brick.
  • the height of the textile fibers constituting the open structure carpet is advantageously between 18 and 25 mm, preferably between 20 and 23 mm in order to ensure sufficient vertical stability for the complex.
  • the textile fibers are preferably made of polypropylene.
  • a loose structure tuft associated with the perforated base which preferably consists of a canvas support impregnated with a layer of latex.
  • the present invention also relates to a method according to claim 6.
  • a carpet of this type is laid on an adequate bottom structure, for example a compacted grave, but also in the case of a restoration of a concrete tennis court, on a conventional concrete base, preferably superficially flattened and regenerated.
  • a first layer essentially of sand, is loaded into the textile support to a height such that a vacuum of the order of 3 mm is left relative to the upper surface of the carpet.
  • a tuft 23 mm high is loaded with a first sub-layer of sand having a particle size of 0.2 / 0.8 mm over a height of approximately 15 mm and a second sand sub-layer having a particle size of 0.2 / 0.3 mm over a height of approximately 5 mm.
  • the particle size of the first sand sub-layer is chosen so as to ensure both good penetration into the mat and its complete permeability, while the particle size of the second sub-layer is chosen so that it can serve as a base for the subsequent layer of crushed brick.
  • crushed brick layer is then placed over a height of approximately 3 mm so as to fill the void remaining on the surface of the textile support.
  • the assembly is compacted by the means usually used for the preparation of clay tennis courts.
  • the profile that is to say the surface appearance of the sand used, is selected to avoid damaging the textile fibers of the carpet. Non-angular shapes both prevent this deterioration while ensuring excellent permeability.
  • This permeability is further enhanced by the existence of holes drilled in sufficient quantity in the base of the latex-coated textile support.
  • the carpet / sand / clay complex can immediately absorb a significant amount of water while waiting for it to infiltrate the foundation layer.
  • the layer will be quickly removed from standing water and the time of immobilization of the ground after a downpour will be reduced.
  • the present invention also offers considerable advantages for the restoration of old tennis courts made of porous concrete and of all hard surfaces on which the product according to the invention can be used after restoration (planing, leveling and drilling ) in order to achieve permeabilization of the surface of this foundation layer.
  • This figure represents a textile support bearing the general reference 1 consisting of a base comprising a canvas support 3 impregnated with a layer of latex 2 in which are fixed by conventional fiber tufting techniques 4 made of polypropylene and having a height about 25 mm, and in a relatively loose structure.
  • the base of the textile support is pierced with openings 5 in order to present adequate drainage.
  • This textile support 1 after having been placed on a flat surface, is loaded with a first sand sublayer 6 having a particle size of 0.2 / 0.8 mm over a height of 15 mm and then a second under layer of sand 7 having a smaller particle size 0.2 / 0.3 mm over a height of 5 mm.
  • a carpet will be chosen whose fibers are "clay" color so as to blend with the crushed brick.
  • the ball rebound qualities are equivalent to those obtained on traditional tennis courts.
  • plastic profile Another possibility is to prepare lines in plastic profile and arrange them on the locations of the official routes. These plastic profiles have the appearance of tubes having a rectangular section of 50 x 23 mm and are glued to the textile support before the sand is placed.
