Definitions
- This invention relates to the construction of playing surfaces, in particular games playing surfaces, and the invention has particular, but not exclusive, reference to surfaces for playing outdoor games and sports or other recreational activities, and for children's playgrounds.
- Sand as a particulate infill whilst being very 'natural' has some unpredictability due to moisture or compaction, along with variations in grading of different sands. This variability has proven satisfactory, with careful selection of the sand, for general multi-purpose use, though it is not predictable enough for better quality sports grounds such as for hockey at higher levels.
- shock pad layers have a degree of elasticity.
- We produce a shock pad layer by introducing loose rubber granules into a fibre shock pad, inside an envelope. This is very effective, but it is costly to construct, as it is done by hand and is labour intensive.
- More rubber and larger particles could be used within the envelope rather than in a fibre shock pad. Problems with larger loose rubber crumb are that if it is disturbed, it does not self-level the in same way as sand or finer crumb. The use of finer rubber in greater depths for greater level stability, can result in too much elasticity so that the surface becomes less stable to play on. This can increase the chance of ankles turning over and other twisting injuries.
- a playing surface for sports or other recreational activities which comprises a water permeable textile envelope containing a layer of mineral particles, an upper layer of the textile envelope bearing a resin bound, adherent, subjacent layer of discrete rubber particles.
- the invention affords a number of advantages. It is very simple to unroll a rolled textile web and thereby rapidly cover even rather extensive playing areas, for example for forming football or hockey pitches.
- the invention accordingly affords considerable advantages in reducing the amount of time required to lay a playing surface incorporating a layer of rubber particles adhered to a textile web. Also, the requirement for lengthy employment of highly skilled labour on site when laying the playing surface is reduced.
- the layer of rubber particles may be applied to the textile web under factory conditions, and accordingly a much greater degree of precision and reproducibility can be obtained than would be possible by applying the rubber particles to form the layer under field conditions. We have also found that it is simpler to form consistent joints between successive textile webs than it is between successive areas of rubber mat.
- the invention includes a method of preparing a playing surface for sports or other recreational activities which comprises laying a first water permeable textile layer to ground, applying thereto a layer of mineral particles, and applying an upper water permeable textile layer bearing a resin bound, adherent, subjacent layer of discrete rubber particles over the mineral layer to form, with the first textile layer, an envelope containing the mineral particles.
- the use of a water-permeable envelope is confers particularly important advantages.
- the adoption of this feature has the further advantage of allowing reconditioning of the playing surface. If the layer of mineral particles, particularly sand or finer particles, is drenched so that it is effectively put into suspension, it may be allowed to drain and rolled, to impart desired playing characteristics.
- a textile web 1 is carried by a conveyor 2 beneath an applicator 3 where a fluid layer 4 of rubber particles in a resin binder is applied.
- the web passes beneath a doctor blade 5 where this fluid layer is levelled and its thickness regulated, and thence beneath an appropriate curing device 6 where the fluid layer is cured to become an adherent resin bound rubber of rubber particles 7.
- an undersheet 8 of a suitable geotextile material is laid down over a prepared area of ground.
- a layer 9 of sand or other fine particulate mineral is screeded over the undersheet 8, and a textile web 1 bearing an adherent layer 7 of rubber particles is applied to the layer of sand 9 with the rubber layer 7 facing downwards to form an envelope.
- the undersheet 8 and the textile web 1 may be bonded together at their margins 10.
- a layer 11 of artificial sports surface such as an artificial turf is then applied.
- the layer of sand 9 is replaced by a layer of angular stone 12, and a protective layer 13 of a suitable geotextile material is incorporated into the envelope between the layer of stones 12 and the rubber-containing layer 7.
- the mineral particles are fine, as in Figure 2, so that interstices between them are small in relation to the rubber particles adhered to the upper textile layer 1, then, if the rubber-containing layer should break down during the course of time it is found that the rubber particles tend to remain as a stable layer between that textile web and the mineral layer.
- the purpose of the protective layer 13 is firstly to delay and breakdown of the rubber containing layer 7, and secondly, to ensure that any rubber particles which become separated remain in a shock-absorbing layer rather than falling through interstices between the stones.
- the textile web used for preparing any of the textile layers of the envelope is suitably a non-woven, needle-punched synthetic fibre mat, for example of polyester, polypropylene or polyamide material.
- a resin binder for any of the textile webs may be chosen to confer appropriate properties, such as a desired stiffness, on the web.
