Definitions

  • the present invention relates to an artificial turf covering according to the preamble of claim 1 and its use for a sports field or playground, in particular a football field.
  • Artificial grass is often used as an alternative to a natural lawn, especially on sports grounds and playgrounds. Compared to the latter, artificial turfs have the advantage that they have a higher load capacity and are relatively easy to care for. In addition, they are playable over a natural lawn even in bad weather.
  • Corresponding artificial turf coverings comprise a turf formed by plastic pile threads which are mounted on a support.
  • it has been proposed to fill it with sand and to weigh it down in this way.
  • An artificial turf filled with sand will be roughly in US 2001/0033902 described.
  • a corresponding example of such a filled artificial turf is about the "granulated artificial grass CASOLON" Prestige System.
  • rubber granules in such filled artificial turf coverings often use a relatively inexpensive recycled rubber, such as SBR.
  • the pent-up water can freeze, which greatly minimizes the shock absorption properties and the grip of the artificial turf.
  • the object of the present invention is to provide an artificial turf covering available, which can be easily maintained and which at the same time allows to ensure a high shock absorption and grip even at low temperatures.
  • the invention is achieved by the artificial turf covering according to claim 1.
  • Preferred embodiments of the invention are given in the dependent claims.
  • the artificial turf covering according to the invention comprises a flat support (also referred to as “back” or “support back”), at least one granulate layer arranged on the upper side of the support and a turf.
  • a flat support also referred to as "back” or “support back”
  • the at least one granular layer comprises a plastic granulate layer arranged directly on the upper side of the carrier.
  • the granulate layer consists essentially only of the plastic granulate layer; There is thus a single layer of granules in the form of the plastic granulate layer.
  • the support of the artificial turf flooring of the present invention is dimensionally stable, whereby the artificial turf is effectively stabilized and thus high local strength can be achieved.
  • wrinkles are thus prevented even when mechanical forces are applied with a relatively large component running parallel to the surface of the artificial turf.
  • the stabilization achieves an increased resistance to a torsional force. As a result, especially when using the artificial turf covering for a football turf, a high degree of movement safety of the players is ensured, for example with jerky rotary movements.
  • polypropylene for example, polypropylene, polyester, polyamide and / or glass fibers can be used.
  • the carrier is preferably formed in two or more layers, wherein it particularly preferably comprises a glass carrier-containing auxiliary carrier.
  • the auxiliary carrier is designed as a layer forming the underside of the carrier. This can be connected to the remaining layer (s) of the backing such as with an adhesive such as a waterproof latex, hotmelt, polyethylene or polyurethane.
  • an adhesive such as a waterproof latex, hotmelt, polyethylene or polyurethane.
  • a particularly high local strength is achieved when the artificial turf covering is screwed or glued to the ground at the edge of the lawn.
  • the present invention also allows to use granule layers of substantially smaller thickness than is the case with the conventional tiled synthetic turf coverings.
  • the granular layer preferably has a thickness of at most 10 mm.
  • the average length of the pile threads is preferably in the range of 2.5 cm to 4 cm.
  • the ratio of the thickness of the granular layer to the length of the pile threads is, according to a preferred example, about 1: 5.
  • the length of the pile threads is the average length measured from the top of the support.
  • a first part of the pile yarns measured from the top of the carrier is measured longer than a second part of the pile threads. It is further preferred that the second part of the pile threads is formed of a stiffer material than the first part of the pile threads.
  • this embodiment of the invention allows on the one hand to obtain a deceptively similar appearance to a natural turf of high authenticity.
  • This can be further increased by using different green shades for the pile threads of the first part and the pile threads of the second part.
  • a lighter green is used for the pile threads of the second part, as for the pile threads of the first part.
  • the said embodiment allows the ball rolling behavior and the ball rebound behavior especially with regard to the use of artificial turf flooring for a football turf.
  • the pile threads of the first part are longer by 5 to 10 mm than the pile threads of the second part.
  • the plastic granulate layer comprises an antistatic plastic granulate.
  • the use of an antistatic plastic granules has the advantage that the users of the artificial turf, ie in particular the football players, are spared from annoying electric shocks.
  • a plastic granulate which shows no electrostatic charge when rubbed.
  • This comprises both plastic granules which are formed from an antistatic material and those which have only an antistatic coating. It is conceivable, for example, that a surfactant is applied to the individual grains of the plastic granulate as an antistatic agent.
  • the carrier is preferably designed such that it is electrically conductive.
  • the reduction in material loss achieved by the prevention of the material debris contributes to the fact that the thickness of the granular layer can be chosen to be relatively low, without the grip of the artificial turf covering being greatly reduced even under intensive stress.
  • the plastic granules comprise ethylene-propylene-diene rubber (EPDM).
  • EPDM ethylene-propylene-diene rubber
  • This in addition to its antistatic properties has the advantage that it is virtually odorless even at high temperatures. Incidentally, discoloration such as ball and clothes is hardly observed when using this material. This is in contrast to the conventional SBR used as plastic granules, which in addition to its high odor due to its dark color Solar radiation takes undesirably high temperatures and its dark abrasion dust, moreover, can discolor the ball and clothing of the players, which is undesirable for obvious reasons.
  • EPDM ethylene-propylene-diene rubber
  • an elastic layer is arranged on the underside of the carrier of the artificial turf covering according to the invention, so that an effective shock absorption is ensured even with a relatively small thickness of the granulate layer.
  • the pile threads are preferably formed from polyolefin, in particular polyethylene or polypropylene.
  • pile threads can be obtained with a very low frictional resistance. Due to the reduced frictional heat, skin burns can be avoided even if a player slips over the artificial turf at a relatively high speed, which is very often the case especially in football games.
  • the pile threads may be at least partially crimped, twisted into each other and / or fibrillated.
  • the yarn count of the pile yarns is preferably in a range of 800 to 3,500 dtex per filament.
  • the turf is preferably produced by means of a tufting process.
  • the turf preferably has a stitch density in the range of 20,000 to 30,000 / m 2 .
  • the advantages of the artificial turf flooring according to the invention come in particular when it is used for one Sports field or playground, especially a football field, to bear.
  • the in Fig. 1 shown filled artificial turf covering 2 ' has a flat support 4', which is arranged on a Elastikunterlage 6 '.
  • two granulate layers are applied to the carrier 4 ', namely one after the other directly on the support arranged quartz sand layer 10' for weighting and stabilizing the artificial turf covering 2 'and on the quartz sand layer 10' arranged Kunststoffgranulat für 12 ' ,
  • Both the quartz sand layer 10 'and the plastic granulate layer 12' are penetrated by pile threads 14 ', which are fastened to the carrier 4' and are present in bundles of fibers 16 '.
  • the pile threads 14 'and the thread bundles 16' protrude out of the granule layers 10 ', 12' and form a turf 18 '.
  • the carrier 4 ', the granule layers 10', 12 'and the turf 18' form the useful part 19 'of the artificial turf covering 2'.
  • the elastic pad 6 lies with its side facing away from the carrier 4' underside 20 'on a bound or unbound first support layer 22 ', which in turn rests on its underside 24' remote from the elastic support 6 'on an unbound second support layer 26'.
  • This runs into a drain 30 'comprising an extension 30', which is filled with round gravel 32 '.
  • a geotextile 36 ' is disposed in the support layer 26' and in the extension 30 '.
  • a first part of the pile threads 14a is longer than a second part of the pile threads 14b.
  • the length of the pile threads 14a of the first part measured from the upper side 8 of the support 4 is approximately 27 mm, while the corresponding length of the pile threads 14b of the second part is approximately 32 mm, so that a difference B of about 5 mm results.
  • the pile threads 14a of the first part and the pile threads 14b of the second part are each arranged in separate thread bundles 16a and 16b, respectively. These are preferably by means of a tufting process in the carrier 4 introduced and connected to this.
  • the legs are of equal length and thus the pile threads 14a and 14b have an identical length measured from the upper side 8 of the support 4, it is conceivable to have legs or pile threads 14a of unequal length in a bundle of threads 14b.
  • the carrier 2 is in the embodiment according to Fig. 2 formed multi-layered and includes underside an auxiliary carrier 17 made of a glass fabric.
  • the carrier 4, the plastic granulate layer 12 and the turf 18 form the useful part 19 of the artificial turf covering.
  • an elastic layer 6 is arranged, which in turn is arranged with its side facing away from the carrier 4 bottom 20 on a support layer 23.
  • Both the elastic layer 6 and the support layer 23 as well as any further support layer or an extension are made of a porous or pebble-like material and thus allow water to seep well.
  • All components of the artificial turf flooring according to the invention are usually made of a rotting and Weatherproof material made, making it suitable for outdoor use.
