Claims
- 1. A wheel, particularly for skateboards or rollerskates, comprising:
- a central hub;
- a plurality of spokes extending radially from said central hub and defining a plurality of interspaces between said spokes; and
- a tire having an outer portion for rolling contact with the ground and an inner portion connected to said central hub, said outer portion and inner portion being mutually interconnected to form said tire;
- wherein said inner portion of said tire comprises a plurality of wings extending at least in the interspaces between said spokes to at least partially fill the interspaces between said spokes, each of said wings having a free end arranged in contact with a wall of said hub and said tire having a radial extension extending from said outer portion to the free ends of said wings, and said plurality of wings having a degree of rigidity which is different than the rigidity of said outer portion of said tire.
- 2. The wheel of claim 1 wherein said hub comprises a cylindrical wall portion and wherein each of said spokes comprises a radial web extending perpendicularly from said cylindrical wall portion and a concentric web extending concentrically with respect to said cylindrical wall portion.
- 3. The wheel of claim 1 wherein said hub comprises a cylindrical wall portion and wherein each of said spokes extends in a helical extension with respect to a central axis of said cylindrical wall portion.
- 4. A wheel, particularly for skateboards or rollerskates, comprising:
- a central hub;
- a plurality of spokes extending radially from said central hub and defining a plurality of interspaces between said spokes; and
- a tire having an outer portion for rolling contact with the ground and an inner portion connected to said central hub, said outer portion and inner portion being mutually interconnected to form said tire;
- wherein said inner portion of said tire comprises a plurality of wings extending at least in the interspaces between said spokes to only partially fill the interspaces between said spokes such that empty spaces without material are arranged in the interspaces between said spokes.
- 5. The wheel of claim 4 wherein said hub comprises a wall, and wherein each of said wings has a free end arranged in contact with said wall of said hub and said tire has a radial extension extending from said outer portion to the free ends of said wings.
- 6. The wheel of claim 4 wherein said plurality of wings has a degree of rigidity which is different than the rigidity of said outer portion of said tire.
- 7. The wheel of claim 4 wherein said hub comprises a wall, and wherein each of said wings has a free end arranged in contact with said wall of said hub and said tire has a radial extension extending from said outer portion to the free ends of said wings, and wherein said plurality of wings has a degree of rigidity which is different than the rigidity of said outer portion of said tire.
- 8. The wheel of claim 4 wherein said hub comprises a cylindrical wall portion and wherein each of said spokes comprises a radial web extending perpendicularly from said cylindrical wall portion and a concentric web extending concentrically with respect to said cylindrical wall portion.
- 9. The wheel of claim 8 wherein said empty spaces are arranged between said cylindrical wall portion of said hub and the concentric webs of said spokes.
- 10. The wheel of claim 4 wherein said empty spaces are arranged directly adjacent said spokes.
- 11. The wheel of claim 4 wherein said hub comprises a cylindrical wall portion and wherein each of said spokes extends in a helical extension with respect to a central axis of said cylindrical wall portion.
