Definitions

  • the present invention relates to a floor covering for sports fields, especially for tennis courts, consisting of a flat, carpet or mat-like base covering and applied to the base covering, consisting of individual, loose particles slip-scattering, the particles of the slip-sprinkling each with a defined shape molded from plastic, in particular extruded.
  • the present invention has for its object to provide a floor covering of the generic type described above, which ensures especially for tennis courts further optimized performance characteristics and does not have the above disadvantages.
  • the particles of at least a subset of the slip-scattering are each formed as a flat lens-like sliding body, each having at least on one side an at least partially convex curved surface.
  • the lens-like sliding body can be formed with two opposite, convex surfaces. It may also be at least one surface to a substantially planar or partially convex training with an approximately central, concave depression or indentation.
  • the sliding bodies have virtually no tendency to curl, but instead their surfaces form sliding surfaces, so that the sliding bodies only have a displacement effect connected to a rotatability about vertical axes due to a stable position in the plane. This has proved to be very advantageous in practical use.
  • the sliding bodies are each formed in plan view at least approximately circular or oval and in particular with a diameter approximately in the range of 1 mm to 4 mm at a thickness measured between the sliding surfaces in the range of 0.5 mm to 2 mm but in any case the diameter should be greater than the thickness.
  • the sliding bodies each have only one side a convex or at least partially convex sliding surface, wherein the opposite surface z. B. can be about flat (plan).
  • the sliders will lie approximately halfway down the convex sliding surface on the base pad and approximately halfway up with the slide face, so that when a foot athlete (tennis player) slides, either the slip bodies with the convex sliding surfaces moved over the base covering or the foot (a shoe sole) slips over the sliding surfaces away.
  • an embodiment of the sliding body with two opposing convex or partially convex sliding surfaces, which then interact in a sliding manner both with the base covering and with the foot or shoe is particularly advantageous.
  • the sliding bodies according to the invention can be produced in a simple manner by extrusion.
  • an extrusion strand is formed with an at least approximately circular profile cross-section.
  • the individual sliding bodies are divided, in particular by a rotating beater blade. Since the material is not yet finally cured, but still plasticized, the convex surfaces form by a swelling effect before or while the particles are cooled by water.
  • the approximately circular or oval cross-sectional shape may also be a polygonal shape with then rounded corners.
  • the slip sprinkling can consist exclusively of sliding bodies according to the invention. It may be advantageous, however, as sprinkling a mixture of terms Insert shape, size and / or material different particles.
  • This mixture consists of a certain proportion of sliding bodies according to the invention and preferably to a certain proportion of Rollkörpem, as they are known from the already mentioned above DE 44 44 030 C2. Due to certain proportions, the sliding properties can be set in a wide range. The higher the proportion of rolling elements, the "smoother" the soil becomes (high slippery slope), and due to low proportions of the rolling bodies, the soil becomes “duller” (less slippery).
  • a floor covering 1 consists of a carpet-like or mat-like base covering 2 and a slip coating 6 applied thereto, consisting of individual loose particles 4.
  • the particles 4 essentially become loose and therefore are relatively movable on the base pad 2, an approximated to ash places characteristic of the floor covering 1 is achieved by a user (tennis player) can slip over the floor covering 1, with displacement of the particles. 4
  • the particles 4 of at least a subset of the slip diffusion 6 are in each case formed as a flat lens-shaped sliding body 8 with preferably two opposite, convex surfaces 10.
  • the sliding bodies 8 are practically not rollable, but have by the convex and thereby sliding surfaces forming surfaces 10 good sliding properties, so that they can be moved in the use of the space in the plane.
  • each sliding body 8 has in plan view an at least approximately circular cross-sectional shape with a diameter D and, according to FIG. 3, a thickness d measured between the convex surfaces 10.
  • the diameter D should in any case be greater than the thickness d.
  • the diameter D is preferably approximately in the range of 1 mm to 4 mm, while the thickness d is approximately in the range of 0.5 mm to 2 mm. In this case, the diameter D should correspond to approximately 1.5 to 3 times, in particular approximately 2 times the thickness d.
  • Fig. 7 and 8 an alternative embodiment of the slider 8 according to the invention is illustrated.
  • a concave depression 11 indentation
  • this surface is “partially convex” and therefore also designed as a sliding surface.
  • this sliding body 8 has a shape reminiscent of a coffee bean or wheat germ.
  • the scattering 6 can consist exclusively of sliding bodies 8 according to the invention.
  • the scattering 6 consists of a mixture of different in terms of shape, size and / or material particles 4.
  • the scattering 6 to certain proportions of inventive sliding bodies 8 and Rollkörpem 12 according to FIG. 5 and 6 together.
  • These rolling bodies 12 are formed with a certain length L which is at least approximately equal to a measured perpendicular to the length L particle width B or B '.
  • these rolling bodies 12 have a tendency to curl or roll at least in one direction about a specific axis.
  • the rolling elements 12 have a cross-sectional shape, which in the direction of both mutually perpendicular surface coordinates each have substantially the same width B, B '.
  • the rolling bodies are "quasi spherical" and therefore have a pronounced tendency to curl in any direction.
  • the width B corresponds to the diameter of the circular cross-section rolling body 12.
  • the width B corresponds to the length of a side edge, while the width B 'results from the diagonal of the square.
  • the width B are shown as the side length of a triangular cross section and the width B 'as the length of the bisecting line or height of the triangle.
  • two slightly different widths B and B ' also result in the exemplary hexagonal polygonal cross section shown in FIG. 6c. Further details can be found in DE 44 44 030 C2, to which reference is made at this point in its entirety.
  • an elastomer in particular of a styrene-butadiene copolymer, such as SBS or SEBS, can be used for the particles 4, ie sliding body 8 and rolling body 12. It may also be a mixture of EPDM with one or more of the other materials mentioned, wherein, for example, at least partially polyuretane (PU) is suitable and / or a material from the group of polyolefins or polyenes.
  • PU at least partially polyuretane
  • a preferred material contains at least styrene-butadiene-styrene (SBS) in combination with polyethylene (PE).
  • SBS polyethylene
  • the material of the particles 4 contains an antistatic additive. Such antistatic agents prevent electrostatic charges and thus advantageously caused by adhesion phenomena.
  • the base layer 2 is basically any known for this purpose carpet. Particularly advantageous in connection with the particles 4 according to the invention, however, is a tufted article, in particular LCL velor. Also well suited is a particular tip-sheared scroll coating. This is a product with cut slings.
  • the base covering 2 may also be formed by an artificial turf material, in particular when used outdoors.
  • Polvlies- or needle felt coverings are suitable, which are then preferably madetreldelt velorig. It is also possible to use structured needle felt coverings, in particular with dimple, fish implement and / or circular structures.
  • a pile fabric according to the above-mentioned DE-U 91 09 798 is basically suitable.
  • the base covering 2 may also be a surface-structured, in particular extruded plastic mat.
  • the scattering 6 is arranged on the base covering 2 with a weight per unit area, which strongly depends on the type and structure of the base covering 2 as well as on the desired chute properties.
  • the basis weight of the particles 4 may be in the range of about 200 g / m 2 .
  • the basis weight can also reach over 10 kg / m 2 , for example.
  • a use in a base covering of tufted loop fabric is favorable, with a basis weight of about 500 g / m 2 is advantageous.
  • the flooring 1 according to the invention is suitable for indoor and outdoor use in sports and tennis courts alike.
  • the invention is not limited to the illustrated and described embodiments, but also includes all the same in the context of the invention embodiments. Furthermore, the invention has hitherto not been limited to the feature combination defined in claim 1, but may also be defined by any other combination of specific features of all individually disclosed individual features. This means that in principle virtually every single feature of claim 1 omitted or by at least one elsewhere in the application disclosed individual feature can be replaced. In this respect, the claim 1 is to be understood only as a first formulation attempt for an invention.
