Abstract
A floor covering, in particular for sport fields, based on elastic plastics, has a substantially flat top side on which one can walk and a bottom side spaced apart therefrom. The covering has an anisotropic elasticity in the desired running direction, so that it dampens more strongly the impact of a shoe of a runner running on the top side in the desired direction than the impact of the shoe of a runner running on the top side in the opposite direction.
Claims18
A support covering for supporting objects, the support surface comprising:
- a material positionable on a base and having a surface contactable with the objects to provide support to the objects, said material having elasticity, said material having elastically anisotropic means for being anisotropic with respect to said elasticity in directions substantially parallel to said surface.
A running surface comprising:
- a base for supporting running in a predominate direction;
- a material positionable on said base and having a exterior contactable with running shoes, said material having elastically anisotropic means being elastically anisotropic with respect to said predominate direction.
