  • Patent number: 4054324
    Abstract: 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.
