Abstract
An in-line skate wheel including a hub that positions and supports a bladder generally about the center line of the hub. The wheel hub comprises an inner surface forming a bore for receiving a wheel axle, an outer circumferential surface spaced from the inner surface and first and second edges. The hub also comprises a center line evenly spaced from the first and second edges of the outer surface. Contoured positioning tabs are located along the circumference of the outer surface and are alternately spaced on opposite sides of the center line to receive and retain the bladder therebetween in order to position it about the center line and support it during the use of the wheel.
Claims38
An in-line skate wheel, comprising:
- a bladder:
- a hub having an inner surface, an outer circumferential surface and a plurality of positioning tabs;
- said inner surface forming a bore for receiving a wheel axle;
- said outer circumferential surface being spaced from said inner surface and having first and second edges and a center line evenly spaced from said first and second edges;
- said plurality of positioning tabs being located along the circumference of said outer circumferential surface and alternately spaced on opposite sides of said center line such that at least two successive tabs are located on opposite sides of said center line, each tab including an inner side wall that is shaped to fit an outer surface of the bladder;
- the bladder being received between and positioned by said positioning tabs out of contact with said outer circumferential surface;
- and
- a tire member completely surrounding said bladder and bonded to said bladder, and to said outer circumferential surface and positioning tabs of said hub by being molded thereto.

A wheel hub comprising:
- an inner axial bore surface;
- an outer circumferential surface spaced from said inner surface and having first and second edges and a center line evenly spaced from said first and second edges;
- and
- a plurality of positioning tabs located along the circumference of said outer surface and alternately spaced on opposite sides of said center line such that at least two circumferentially successive tabs are located on opposite sides of said center line, said tabs having means for locating a bladder generally in-line with said center line and out of contact with said outer circumferential surface, wherein said means for locating a bladder includes an inner side wall which is shaped to fit an outer surface of the bladder.
