    摘要： A sports ground, in particular a tennis court or mini court, is provided using removable panels which are each laid on an isolating plate, and the plates themselves rest on the previously levelled ground through a textile sheet. Connection between the panels is provided by channel sections whose upper horizontal part is fixed to the underface of the facing edges of the panels to be assembled and is extended by vertical flanges. A space is provided between the panels and is extended through openings in the horizontal part of the channel sections for allowing removal of rain water.

    摘要： A system is provided for removing snow and ice from and for subsequently drying an athletic playing surface such as a tennis court, basketball court, or the like. The system includes a porous playing surface mounted above a plenum chamber. A heating unit or furnace is associated with the chamber to introduce hot gases in the chamber under pressure sufficient to cause them to pass up through the porous surface. These hot gases then serve to melt the snow and dry the surface. The openings in the porous surface should be large enough to permit up-flow of the gases and drainage of the melted snow, but small enough so as to not adversely affect play on the surface.

    摘要： A support layer for supporting an artificial turf assembly. The support layer being formed of a polymeric foam, preferably having a density of between 20 and 70 grams per liter, such as a polyolefin foam; and having an upper side and a lower side, wherein in use the support layer has been placed with the lower side thereof on a base surface and supports, on the upper side thereof, the artificial turf assembly, the support layer including a plurality of through drainage holes extending from the upper side to the lower side for allowing liquid such as rain water to flow via the plurality of drainage holes from the upper side to the lower side, and also including a plurality of channels at the lower side for allowing liquid such as rain water to flow through the channels along the lower side, wherein each of said plurality of drainage holes debouches into one of the plurality of channels. The support layer is further included in an artificial turf system, that includes an artificial turf assembly with the support layer supported on a base surface such as a layer of sand, wherein the support layer forms, at the upper sides thereof, a closed support surface supporting the artificial turf assembly.

    摘要： An artificial turf system defining a playing area comprises an artificial turf layer with an air distribution layer located beneath the turf layer, by which air can be distributed throughout the playing area. The air distribution layer is closed at edge regions to define a periphery of the playing area and an air supply is in fluid communication with the air distribution layer to provide a flow of air. A flow regulating layer is located between the air distribution layer and the turf layer, the flow regulating layer being provided with a plurality of openings arranged to allow permeation of air through the turf layer within the playing area. The proposed system allows air to be distributed uniformly over the whole of the playing area for cooling of the turf layer.
