Abstract
A bicycle wheel with composite fiber resin spoke and rim structures having opposing spokes radiating from a central hub, the spokes being filament wound continuously one to the other across the central hub. The configuration provides for lower resistance to lateral wind, and for light weight resulting from the use of composite structures with fibers substantially oriented to resist wheel loads.
Claims29
A bicycle wheel comprising:
- a generally circular central hub having a body carrying an axial bore for receiving an axle and bearing assembly;
- a circular rim structure concentric with the hub, for receiving a tire on the outermost circumference thereof;
- a multiplicity of elongate spoke structures, each having an outermost tip at the rim structure and an innermost end at the hub and each extending radially outwardly from the hub, with the tip thereof abutting the rim structure;
- means securing the inner end of each of the spoke structures to the hub;
- and
- means securing the outermost tips of each of the spoke structures to the rim structure;
- wherein
- the body of the hub includes a portion at each end thereof extending radially outwardly from the hub, said portion having an outwardly facing generally planar surface;
- each spoke structure comprises a pair of spaced apart spoke side members, each of said side members extending from an associated outside hub body surface to join with the spoke structure tip;
- the multiplicity of spoke structures comprises radially opposite pairs of the spoke structures, the spoke structures of each of said pairs extending oppositely from the hub aligned with each other along a diameter of the wheel;
- and wherein each pair of opposing spoke structures comprises fiber filaments continuous at least from tip to opposing tip placed radially to the wheel from spoke side members to diametrically opposing spoke side members across the associated intervening outwardly facing hub body planar surface.
