Patent ID: 8506897

Claim:
A vehicle to move across a synthetic sports field having synthetic blades with opposite sides to destroy infectious material on said field comprising: a frame: a wheel rotatably mounted on said frame and extending downwardly to support said frame as said frame is moved across a sports field; a source of ultraviolet light mounted on said frame and having ultraviolet lamps to shine downwardly against blades on the field; a source of electrical energy mounted on said frame and connected to said ultraviolet lamps; and, a brush mounted on said frame forwardly of said source of ultraviolet light and having bristles extending down contacting and positioning the blades on the field to extend generally vertical and receive said ultraviolet light on both opposite sides of the blades and destroy infectious material thereon; wherein said field includes loose material positioned between the blades and further comprising: a plurality of wire shaped tines mounted to said frame to contact and move loose material between said blades to expose said loose material to said ultraviolet light as the frame moves across the field while said ultraviolet light shines on said loose material to destroy infectious material thereon, said tines have wire shaped bodies with proximal ends spring mounted to said frame and free distal ends enabling said bodies to pivot from a forward position to a rearward position when said distal ends engage immovable objects and to then spring back to said original position once past said immovable objects; and, a lifting apparatus on said frame to move said tines to control the amount of penetration by said tines into said loose material.
