Skate wheel

Abstract:

A skate wheel includes an outer polymeric layer, an inner polymeric layer, and an intermediate layer. The inner polymeric layer has a hardness which is less than the hardness of the outer polymeric layer. The inner and outer polymeric layers are preferably comprised of polyurethane. The intermediate layer is made of a hard plastic or metal that extends through the cross-section of the roller wheel, separating the outer and inner layers. The intermediate layer prevents compression of the harder outer polymeric layer onto the softer inner polymeric layer. This provides a smoother ride while maintaining good precision and speed. The skate wheel may also include a decorative illumination device.

Claims:

What is claimed is:

1. A skate wheel comprising: an outer polymeric layer, having an outer surface; an inner polymeric layer having a hardness which is less than the hardness of said outerpolymeric layer, having an outer surface; a metallic intermediate layer, having an outer surface, completely separating said outer polymeric layer from said inner polymeric layer; and a central hub surrounded by said inner polymeric layer, wherein saidouter surfaces of said outer polymeric layer, said inner polymeric layer, and said intermediate layer are flush on at least one side of said skate wheel wherein said hub is flush with at least one of said outer surfaces.

2. A skate wheel as claimed in claim 1, wherein said central hub is recessed on a side of said skate wheel.

3. A skate wheel as claimed in claim 1, wherein said central hub is flush with said outer surfaces of said inner polymeric layer, said intermediate layer, and said outer polymeric layer.

4. A skate wheel as claimed in claim 1, wherein said central hub comprises aluminum.

5. A skate wheel as claimed in claim 1, wherein said inner polymeric layer comprises polyurethane.

6. A skate wheel as claimed in claim 1, wherein said outer polymeric layer comprises polyurethane.

7. A skate wheel as claimed in claim 1, wherein said inner layer has a Shore A hardness of about 45 to 75.

8. A skate wheel as claimed in claim 1, wherein said outer layer has a Shore A hardness of about 80 to 95.

9. A skate wheel as claimed in claim 1, wherein said intermediate layer comprises plastic or metal.

10. A skate wheel as claimed in claim 9, wherein said metal is aluminum.

11. A skate wheel as claimed in claim 10, wherein said illumination device is positioned in said inner layer.

12. A skate wheel as claimed in claim 1, wherein said intermediate layer comprises a smooth inner cylindrical surface and a smooth outer cylindrical surface.

13. A skate wheel as claimed in claim 1, wherein said intermediate layer is rigid.

14. A skate wheel as claimed in claim 1, further including an illumination device.

15. A skate wheel as claimed in claim 1, wherein said outer polymeric layer, said inner polymeric layer, and said intermediate layer form annular layers around a central hub.

16. A skate wheel comprising: a generally annular central hub; an inner generally annular polymeric layer surrounding said central hub; a generally annular intermediate layer surrounding said inner polymeric layer; and an outer generallyannular layer surrounding said intermediate layer, said outer layer having a hardness which is greater than the hardness of said inner polymeric layer, wherein said generally annular central hub, said generally annular inner polymeric layer, saidgenerally outer polymeric layer, and said generally annular intermediate layer are flush on a first side of said skate wheel, and wherein said generally annular central hub is recessed on a second side of said skate wheel.

17. A skate wheel as claimed in claim 16, wherein said generally annular intermediate layer comprises plastic or metal.

18. A skate wheel as claimed in claim 17, wherein said metal is aluminum.

19. A skate wheel as claimed in claim 16, wherein said generally annular intermediate layer comprises a smooth inner cylindrical surface and a smooth outer cylindrical surface.

20. A skate wheel as claimed in claim 16, wherein said generally annular intermediate layer is rigid.

21. A skate wheel as claimed in claim 16, further including an illumination device positioned in said generally annular inner polymeric layer.
