Benefits of technology

The invention provides an artificial grass field that is easy to maintain and has improved playing characteristics. The base layer of the field comprises a material with damping properties, which helps to absorb energy and shocks. The material can be worked into the field during manufacturing, saving time and labor. The material can also have moisture-absorbing properties and can be fixed to the base layer. The base layer can have a closed or open structure, making it suitable for use in a hybrid grass field or combination grass field. The damping material can be made from rubber or synthetic foam, with the latter being more player-friendly and reducing the risk of injury.

Problems solved by technology

This leads to a considerable saving of labour.

Embodiment Construction

[0029]For the sake of clarity, parts corresponding to each other are indicated by the same numerals in FIGS. 1a-1h. The artificial grass lawn according to the invention is built up of a base layer 1, on which artificial grass fibres 2 are present. Fibres 2 are fixed in base layer 1 at 3, for example by means of a weaving, knitting or tufting technique. Usually, artificial grass fibres 2 comprise several fibres 2a, 2b, 2c, etc., so as to come as near to the structure of natural grass as possible. By filling the spaces between said artificial grass fibres 2 with a granular material, such as grains of sand or of a synthetic material, the standard artificial grass lawn will have a softer, damping surface, whilst in addition the field will exhibit much improved playing characteristics.

[0030]As already noted above, there are still a number of drawbacks attached to filling the spaces between the fibres of artificial grass fields, one of the major drawbacks being the fact that the originall...

Abstract

The invention relates to an artificial grass lawn suitable for sports fields, which artificial grass lawn consists of a base layer, on which first artificial grass fibres are disposed. In accordance with the invention, the artificial grass lawn is characterized in that said base layer comprises a material having damping properties, which is present thereon and / or therein. Thus the properties of a natural grass field are approximated very closely, and also the style of play on the sports field is positively affected. Furthermore, the artificial grass field thus obtained is substantially free of maintenance and of injury.

Description

[0001]This application is a continuation of U.S. application Ser. No. 11 / 112,009 filed Apr. 22, 2005, which is a continuation of U.S. patent application Ser. No. 10 / 297,609 filed Apr. 22, 2003, which is a nationalization of PCT / NL01 / 00448 filed Jun. 14, 2001 and published in English.BACKGROUND OF THE INVENTION[0002]The invention relates to an artificial grass lawn suitable for sports fields, which artificial grass lawn consists of a base layer, on which first artificial grass fibres are disposed.[0003]Many sports, such as field hockey, tennis, American football and so forth, are played on artificial grass fields these days, which sports fields comprise artificial grass lawns as referred to in the introduction. Although sports people sustain fewer injuries due to falling, making slidings, etc. on natural grass fields, due to the soft surface thereof, such sports fields are hard worn, in particular by the aforesaid sports, owing to the intensive use that is made thereof and the changi...
