Definitions

  • the invention relates to an artificial grass system for forming a field of grass comprising artificial blades of grass distributed at a main surface and provided with liquid supply means for supplying a liquid to said main surface.
  • the invention moreover relates to a artificial grass mat, an artificial field of gras and a method of improving a field of grass.
  • European patent nr. 1080274 describes an artificial lawn of grass consisting of hollow artificial blades of grass having a U-form. These artificial blades of grass are supposed to receive liquid from natural rain or sprinkled water and humidity in the air. To facilitate the entrance of liquid within the hollow core, small pores are provided in the tuft walls of said blades to allow air within said core to escape. Water can enter the hollow cores through the same openings.
  • a disadvantage of this known artificial grass system is the limited amount of water which may be absorbed and stored in the grass blades and accordingly may subsequently be released upon playing on the field. As a consequence the system will soon be depleted and no longer fit for further use as long as the blades are filled again.
  • the object of the present invention is inter alia to provide an artificial grass system which may be applied to avoid these and other disadvantages.
  • an artificial grass system of the type described in the opening paragraph according to the invention is characterized in that said liquid supply means comprises a liquid release layer underneath said artificial blades of grass and in that said artificial blades of grass comprise at least one capillary channel extending from within said liquid release layer to said main surface.
  • Said artificial blades generally will have a substantial straight thread-like form with their channels opening at opposite ends. The blades may be slightly bend, particularly at their ends. Liquid, particularly water is supplied by the liquid release layer and fed to the main surface by the capillary channels within said artificial grass blades. This is a self controlled and adjusting process governed by the capillary action of these channels.
  • the capillary channels upon losing liquid, will fill themselves again with liquid from the release layer and carry this to the main surface. As the main surface becomes depleted more liquid will thus be supplied by the channels to counteract a dry main surface. Because liquid is continuously fed from underneath the main surface, the field may be continuously be played on and requires no further maintenance.
  • These capillary blades of grass may be provided al over the field of grass or inserted in between conventional artificial blades or natural blades of grass.
  • the artificial grass system according to the invention is characterized in that said liquid release layer comprises a liquid absorbing and releasing layer, particularly one comprising at least one material taken from a group of felt, cotton and soil.
  • a liquid absorbing and releasing layer particularly one comprising at least one material taken from a group of felt, cotton and soil.
  • felt and cotton have a large capability both to absorb and release liquid, and hence turn out to be capable of easily and quickly releasing sufficient amounts of water to keep the main surface sufficient wet under varying conditions.
  • the artificial grass system according to the invention is characterized in that said artificial grass blades comprise the at least one capillary channel as at least one artificial nerve within an artificial leave.
  • the blades may thus each comprise one or more capillary channels to carry liquid from the release layer to the main surface.
  • a further embodiment of the artificial grass system according to the invention is characterized in that said artificial grass blades extend along a tubular core which comprises the at least one capillary channel.
  • the core may looks like an artificial back bone of the grass blade to give it a natural appearance and may be scaled to comprise a number of capillary channels to enhance the liquid feeding power.
  • a further special embodiment of the artificial grass system according to the invention is characterized in that said tubular core is filled at least in part with a liquid conductor, more particularly one with said liquid conductor comprising a hydrophilic material, preferably taken from a group of cotton and sponge.
  • a liquid conductor may entirely fill the tubular core for instance in the form of a nucleus of sponge or a thick wire of cotton, to enlarge the capillary effect.
  • said artificial grass system according to the invention is characterized in that said tubular core comprises a tube wall of a material taken from a group of silicon, polypropylene, polyethylene and teflon.
  • the artificial grass system according to the invention is characterized in that said liquid release layer is provided on a buffer layer capable of at least temporarily storing said liquid.
  • this buffer layer comprises rubber, more particularly sintered rubber, capable of storing a lot of liquid for instance by irrigation, and releasing the liquid again as soon as the liquid release layer needs it.
  • the rubber layer moreover provides for a shock damping action which renders the field more comfortable to play on and less prone to bone injuries among the players.
  • the artificial grass system according to the invention is characterized in that said artificial grass blades are incorporated in a support layer with one end projecting from said support layer to penetrate the liquid release layer and an opposite end projecting from said support layer at said main surface. More particularly, a further preferred embodiment of the artificial grass system according to the invention is characterized in that said artificial grass blades are interweaved in said support layer.
  • the support layer is for instance made of latex or a suitable, durable fabric.
  • a field of grass and a grass mat are characterized in that they comprises at least in part the artificial grass system according to the invention.
  • a method of improving a field of grass, according to the invention is characterized by by inserting artificial grass blades of the artificial grass system according to invention within said field of grass.
  • the present invention provides processes to prepare and improve several types of artificial grass field.
  • the artificial field of grass maybe provided with capillary blades according to the present invention all over the surface.
  • the capillary blades may be provided and inserted in an existing field of grass in between existing natural or artificial grass blades, the latter being solid.
  • a process to improve the quality of a natural field of grass is provided by the application of capillary blades between natural blades of grass in which case generally the liquid will be adsorbed up from the groundwater form the underlying liquid release layer of soil.
  • the capillary tubes or capillary nerves are for instance applied to repair the bad parts of an artificial or natural grass field.
  • the capillary blades which are to be applied in this way have to have a length of about 10 - 25 cm, preferably between about 15 - 20 cm, to be able to reach the ground water.
  • the known problems of hurting or burning the skin when someone slides over an artificial grass associated with known artificial fields of grass are solved by the grass system of the invention in which system the supply of liquid is provided by irrigation in stead of by the rain or sprinkling, which means that the quantity of liquid supplied may be regulated.
  • the field will be irrigated either by supplying water to the liquid release layer, or more preferred, by supplying water to a water buffer layer from which layer water will be transferred to the liquid release layer. Besides by sprinkling or direct irrigation the amount of liquid stored in any of the layers is also replenished during natural rain.
  • the openings at both ends of the capillary channels are about the same.
  • the liquid release layer such as a felt layer
  • the capillary channels will absorb an amount of liquid, generally water, what is as large as possible and will release this when there is a pressure on the artificial grass surface, especially when a sliding-tackle is made on the grass field.
  • liquid from the capillary channels, absorbed from the felt layer will be fed to the surface upon contact of someone's body with the artificial blades of grass.
  • This liquid has a sort of lubricant or quenching function especially when someone's skin is hurt like burned by the artificial grass field.
  • the emptied capillary channels will fill themselves again with liquid.
  • the constant process of evaporation will bring on the player a feeling of cool grass which causes generally a large advantageous psychological effect.
  • the new capillary artificial grass field is formed when the new capillary grass mat comprising blades of grass, capillaries between or inside the artificial blades of grass and a support layer is applied on a second layer made of material which is able to adsorb liquid and to release it easily, for instance made of felt.
