Definitions

  • the present invention relates to a turf system for sports or decorative use both for professional and amateur levels, with artificial, or mixed artificial and natural grass.
  • the invention furthermore, relates to a method for positioning such turf system.
  • an artificial turf is essentially constituted by a mat made of a plastic material to which blades, also called “bristles”, having a length comprised between 3 and 10 cm, and that are made of synthetic material, normally polyester, are fixed, in order to form a turf of synthetic grass.
  • the blades made of synthetic material are knitted to the mat by known processes which allow to obtain a warp of blades, which are close to each other according to the needs.
  • an infill material also simply said "infill” is distributed.
  • This is, normally, granular-shaped, and is chosen both on the basis of the type of sport to which the synthetic grass is for, for example soccer, hockey, cricket, rugby, but also on the basis of the most common weather conditions where it is placed.
  • the infill material essentially provides a drainage action, because it adjusts the flow of the rain or irrigation water, protecting the mat in such a way to provide to the artificial turf a high duration over time, but, above all, it provides to the turf mechanical, physical and technological properties similar to those of the natural turfs, and sometimes even better.
  • infill material The most important properties of an infill material are, in particular, the elasticity of the ground for the user, the rebound of the ball, the capacity of shock absorption when falling down, tensile and torque resistance to the force caused by the shoe, the resistance against compression, and penetration of external bodies, as well as the capacity of absorption and drainage of water in case of meteorological and environmental events
  • the drainage action of the synthetic turf is, normally, carried out by a base portion, or "stabilizing infill” that is normally constituted by sand. Instead, the elasticity of the turf is, normally, assured by the presence of granules of rubber, which are concentrated in the upper portion of the turf, or "performance infill”.
  • stabilizing infill that is normally constituted by sand.
  • performance infill An example of a similar infill material is described in US2002/081399 .
  • the artificial turf is normally placed upon a base member that is able to carry out a drainage action.
  • a similar base member provides a first and a second sheet made of a synthetic material normally constituted by two layers made of perforated nonwoven fabric, commonly polyester, between which a material having a granular, or reticular, shape, or in the form of woven blades, for example made of nylon, is arranged.
  • a further drawback of the prior art base members is that since, as described above, they have made of synthetic materials, when they have to be removed, for example to be replaced with new base members, these kinds of material have to be sent to sanitary landfills, with high costs, in addition to the not insignificant high environmental impact that these materials have on the environment.
  • the drainable panel comprises an element provided with synthetic grass having an upper surface from which blades made of synthetic grass protrude, and a lower surface, opposite to the upper surface, to which an elastically deformable layer provided with transversal drainage holes is non removably fixed.
  • the element provided with synthetic grass is fixed to the elastically deformable layer by a thermos-adhesive glue.
  • the drainable panel can also comprise a reinforcement sheet made of a material formed from fibres which are interlaced but not woven. The reinforcement sheet can be positioned between the element provided with synthetic grass and the elastically deformable layer, and can be fixed only to this latter.
  • the fibres of the reinforcement sheet can be fibres of glass, carbon, or fibres of a polyester, or fibres of rock wool, or made of cotton.
  • the drainable panel described in EP1900874 has to be sent to landfills and has a high environmental impact because it provides to use a thermo-adhesive glue to fix the member provided with synthetic grass to the elastically deformable layer.
  • an object of the present invention to provide a turf system made of synthetic grass, or mixed synthetic and natural, which is able to considerably reduce with respect to the prior art turf systems the amount of material to be sent to the sanitary landfills.
