Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
109 words
A hub cap for bicycle wheel axles comprising a circular hub member having a substantially S-shaped radial cross sectional configuration, said hub member being provided with a centrally disposed aperture therein, an axle attachment washer disposed within said aperture and slidably disposed on the wheel axle, and means for removably securing the washer to the hub member, and wherein the outer portion of the hub member extends outwardly away from the wheel to a point beyond the end of the wheel axle and wherein the outer edge of said hub member curves back towards the wheel thereby forming an annular protective surface around the end of the wheel axle.
Claim 2
Dependent Claim
109 words
A hub cap for bicycle wheel axles comprising a circular hub member having a substantially S-shaped radial cross sectional configuration, said hub member being provided with a centrally disposed aperture therein, an axle attachment washer disposed within said aperture and slidably disposed on the wheel axle, and means for removably securing the washer to the hub member, and wherein the outer portion of the hub member extends outwardly away from the wheel to a point beyond the end of the wheel axle and wherein the outer edge of said hub member curves back towards the wheel thereby forming an annular protective surface around the end of the wheel axle.
Claim 3
Dependent Claim
32 words
A hub cap for bicycle wheel axles as set forth in claim 1 wherein the center portion of the hub member is constructed of a thicker material than the outer portion thereof.
Claim 4
Dependent Claim

Claim 6
Dependent Claim
227 words
A hub cap for bicycle wheel axles comprising a circular hub member having a substantially S-shaped radial cross sectional configuration, said hub member being provided with a centrally disposed aperture therein, an axle attachment washer disposed within said aperture and slidably disposed on the wheel axle, and means for removably securing the washer to the hub member, and wherein the outer portion of the hub member extends outwardly away from the wheel to a point beyond the end of the wheel axle and wherein the outer edge of said hub member curves back towards the wheel thereby forming an annular protective surface around the end of the wheel axle, and wherein the washer is cylindrical in shape and is provided with an outwardly extending flange therearound and wherein the means for removably securing the washer to the hub member comprises an annular groove disposed within the hub member aperture, a flared recess provided in the outer end of the aperture between the outer face of the hub member and the groove, the diameter of the cylindrical washer is substantially equal to the diameter of the aperture and the diameter of the flange is substantially equal to the diameter of the groove whereby the cylindrical washer is inserted into the aperture and the flange is passed through the flared recess and snapped into the groove within the aperture.
