Abstract
Abstract Wheel, particularly for skateboards or rollerskates, including a central hub with radial spokes, and a tire which is connected to the hub and which has wings arranged in the interspaces delimited by the radial spokes and the central hub. The wings are arranged to only partially fill the interspaces between the spokes such that empty spaces without material are arranged directly adjacent the spokes. The wings may have a degree of rigidity which is different than the rigidity of the outer portion of the tire.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
155 words
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.
Claim 2
Dependent Claim
155 words
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.
