A sliding device for sliding on the ground down a sloped or inclined surface (grass, dirt, sand, synthetic turf, etc.) has an upper deck and a slide mechanism mounted below and in parallel with the upper deck. The slide mechanism has a slide base of an elongated planar member with opposite radiused ends, and an endless anti-friction belt entrained to slide around the slide base. The belt can be made of high-density plastic, rubber, or a track belt. The slide base surfaces and inner surfaces of the belt may be coated with plastic laminating material to increase slipperiness. The slide base has ends of selected radius of curvature to generate friction forces with the moving belt that provide a "speed limiting" function that slows the device from excessive speeds. In a preferred embodiment, the sliding device is shaped as a body board made of foam material having the slide mechanism recessed in a cavity formed within the bottom of the body to keep the rider's hands or feet from contacting the moving belt. The device may also be configured in various other products for sliding like a sled, a ski, or a skateboard.

The invention claimed is: 1. A sliding device for sliding on the ground down a hill or inclined surface, comprising: an upper deck having opposite lateral sides and a flat surface of a predetermined width extending between said lateral sides sufficient for supporting a rider thereon, and a slide mechanism mounted spacedly below and in parallel with the upper deck, having a slide base formed by an elongated planar member having opposite lateral sides and top and bottom flat surfaces of a width substantially matching the width of the upper deck and provided with opposite radiused ends, and a single, endless anti-friction belt entrained in a lengthwise direction around the slide base and extending across the width between the lateral sides thereof and adapted to slide around the top surface, radiused ends, and bottom surface due to the force of sliding friction contact with the ground, wherein the planar member surfaces and radiused ends and endless belt are selected so as to have anti-friction properties to permit the endless belt to slide around the slide base and enable the sliding device to slide down the hill or inclined surface. 2. A sliding device according to claim 1, wherein said upper deck is mounted on top surfaces of a pair of spaced-apart side rails, and the slide base is mounted to the side rails in the space between them, and wherein said slide base has a thickness and is mounted to the side rails at a position so as to have its bottom surface extending beyond the bottom surface of the side rails by a given height to space the side rails from contact with the ground. 3. A sliding device according to claim 2, wherein said slide base is mounted to the side rails so that its top surface is spaced by a given gap from the bottom surface of the deck to allow movement of the endless belt therebetween. 4. A sliding device according to claim 1, wherein said slide base is formed a top cover sheet, a bottom cover, a left side brace, a rear brace, a right side brace, and a front brace around the lateral edges of the slide base between the top and bottom cover sheets, and a front radius is mounted to an outwardly-facing surface front brace, and a rear radius is mounted to an outwardly-facing surface of the rear brace. 5. A sliding device according to claim 4, wherein said slide base has supports provided between the cover sheets and the braces. 6. A sliding device according to claim 5, wherein the supports are made of a material selected from the group consisting of laminate, cardboard, foam, and honeycomb material. 7. A sliding device according to claim 1, wherein said belt is made of a polycarbonate plastic sheet, rated at a temperature in the range of 240�� F. or more, with a thickness in the range of 0.020 inch or more. 8. A sliding device according to claim 1, wherein said belt is made of a rubber sheet having an anti-friction film applied to its inner surface. 9. A sliding device according to claim 1, wherein said rubber belt has striated segments formed in its outer surface to increase flexibility in sliding around the slide base and to reduce suction or adhesion with the ground surface. 10. A sliding device according to claim 1, wherein said belt is formed as a traction belt having thick segments alternating with joint segments of lesser thickness to increase flexibility in sliding around the slide base and to reduce suction or adhesion with the ground surface. 11. A sliding device according to claim 1, wherein said deck is made of a foam substrate covered by an outer layer of high-density plastic. 12. A sliding device according to claim 1, wherein said deck is made of molded foam formed in a shape of a body board. 13. A sliding device according to claim 1, wherein said deck is made of a body substrate of a given thickness and has a cutout formed into its bottom surface for accommodating the slide mechanism therein. 14. A sliding device according to claim 13, wherein the cutout in said deck is formed so that the slide mechanism is recessed in the body cutout to provide a gap of about ⅝" between the bottom surface of the body and the ground. 15. A sliding device according to claim 13, wherein the cutout in said deck is formed so that the slide mechanism is recessed in the body cavity to prevent the rider's hands or feet from contacting the moving belt. 16. A sliding device according to claim 1, wherein said slide base is coated with a polyester laminating coating to provide a slippery surface for the belt to slide on. 17. A sliding device according to claim 1, wherein said deck is provided on its top surface with handrails to provide handles or rests for the rider to hold or grip onto. 18. A sliding device according to claim 1, wherein said slide base is formed with radiused ends of selected radiuses to generate friction forces with the moving belt that provide a "speed limiting" function that slows the sliding device from excessive speeds. 19. A sliding device according to claim 18, wherein said slide base ends have a radius of curvature of about ⅝ inch. 20. A sliding device according to claim 1, wherein said device is configured in a product for sliding use as one of a group consisting of a body board, a sled, a ski, and a skateboard.
