Spoked wheel particularly for miniature vehicles, comprising a tubular member constituting the wheel hub. At one end the latter is provided with an outer collar. A washer is laid over the tubular member. A sleeve overlies the tubular member between the washer and the collar such as to define two respective annular grooves therebetween. A pair of rims is arranged concentrically with the tubular member and having an inner edge which defines an axially projecting annular ridge. The rims are arranged in a mirror image relationship to each other, so that they also act as shoulder members for the beads of the wheel tire. A ring spacer concentrical to the tubular member and intervening between the rims, defines together with the rims respective annular seats. A pair of spoke-carrying rings is positioned within the annular seats and each provided with circumferentially arranged projections at equal angles apart for hooking a bent over wire over and around the projections. Rivets and a locking nut are provided for clamping in one component the rims and spacers and spoke-carrying rings, and the other end of the tubular member is clenched for locking axially the washer and sleeve against the collar.
A spoked wheel particularly for miniature vehicles, characterized in that it comprises a tubular member constituting a wheel hub and having at one end an outer collar, at least one washer overlying said tubular member, a sleeve overlying said tubular member between said washer and said collar such as to define two respective annular grooves therebetween, a pair of rims arranged concentrically with said tubular member and each rim having an inner edge which defines an axially projecting annular ridge, said rims being arranged in a mirror image relationship to each other, thereby said ridges also act as shoulder members for the beads of the wheel tire, at least one ring spacer concentrical to said tubular member and intervening between said rims, said spacer having a thickness dimension which is smaller than the length of said sleeve and defining together with the rims respective annular seats, a spoke forming wire, at least one pair of spoke-carrying rings positioned within said annular seats and each provided with circumferentially arranged projections at equal angles apart for stretching said spoke forming wire between successive diametrically opposite said projections and bending it over said projections thereby obtaining radial lengths thereof passing between said spacer and said rims and extending tangentially past said tubular member at said annular grooves, means for clamping in one component said rims and spacers and spoke-carrying rings, and means for locking axially said washer and sleeve against said collar.
