Abstract
There is described a two-part artificial ski slope surface comprising a looped filament carpet and a resilient base layer and in addition a looped filament carpet which may be attached to a base layer. The looped filament carpet provides a continuous carpet pile, which may have a random directional weave and loops of different heights to provide different surface characteristics in addition, the material used for the looped filament carpet may also be selected to provide different surface characteristics. The characteristics of the surface are selected to provide surface having different degrees of difficulty and for allowing for different frictional contact between the surface and the user, thereby controlling the speed of the user over the surface.
Claims27
An artificial ski slope for laying on an underlying surface, said artificial surface comprising;
- a looped filament carpet;
- and
- a resilient base layer, and said carpet being releasably attached to said base layer.
A looped filament carpet for use in an artificial ski slope surface, said carpet comprising:
- a backing sheet having an upper and lower surface;
- filaments woven through said backing sheet to provide a pile which is continuous across the backing sheet;
- and
- releasable attachment means secured to said lower surface.
A method of constructing an artificial ski slope, said hod comprising the steps of:
- (a) attaching a shock absorbent base layer to an underlying surface;
- and
- (b) releasably attaching a looped filament carpet to said base layer.
