Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
A wheel construction for a vehicle, said wheel construction comprising a central hub for connection to a shaft, a plurality of spokes extending radially outwardly from said hub, said spokes each being internally hollow and of flared configuration in the radially outward direction generally throughout their length, a rim having a pair of spaced flanges for retaining a pneumatic tire extending concentrically about said hub and fixedly secured to the outer ends of said spokes, the internal hollow of each spoke opening at its radially outer end through the adjacent region of said rim, a plurality of generally sector-shaped webs each extending between the radially inner end regions of an adjacent pair of said spokes, and said hub, spokes and rim being integrally fabricated of plastic material.
Claim 2
Dependent Claim
