Abstract
A multi-part lightweight easily extruded or molded wheel rim and wheel particularly for cycling with joined flanges which extend radially inwardly toward the center of the rim and wheel provides strength not found in conventional channel shaped rims. The radially extending flanges are provided with apertures for receiving bent ends of spokes for assembling the rim and a hub to form a wheel which receives an inflatable tubeless or tube tire which need not be dismounted from the rim when repairing or replacing spokes.
Claims22
A multi-part rim for a cycle wheel comprising an annular first rim member having an integrally formed tire retention bead and a radially inwardly extending flange laterally offset from said bead, an annular second rim member having an integrally formed tire retention bead and a radially inwardly extending flange laterally offset from said bead, said flanges of said first rim member and said second rim member being affixed together and said beads being laterally spaced apart to define a wheel rim, and at least one of said flanges having circumferentially spaced spoke retention apertures therein, wherein said flanges are of varying radial extent around the circumference of said rim.
A multi-part rim for a cycle wheel comprising an annular first rim member having an integrally formed tire retention bead and a radially inwardly extending flange laterally offset from said bead, an annular second rim member having an integrally formed tire retention bead and a radially inwardly extending flange laterally offset from said bead, said beads being laterally spaced apart to define a wheel rim, and at least one of said flanges having circumferentially spaced spoke retention apertures therein, further comprising a third annular rim member having spaced radially inwardly extending flanges respectively affixed to said radially extending flanges of said first and second annular rim members, said third annular rim member having an imperforate annular lateral extent between said flanges of said third annular rim member.
A multi-part rim for a cycle wheel comprising an annular first rim member having an integrally formed tire retention bead and a radially inwardly extending flange laterally offset from said bead, an annular second rim member having an integrally formed tire retention bead and a radially inwardly extending flange laterally offset from said bead, said flanges of said first rim member and said second rim member being affixed together and said beads being laterally spaced apart to define a wheel rim, and at least one of said flanges having circumferentially spaced spoke retention apertures therein, wherein at least one of said members includes weight reduction recesses therein.
