Abstract:
A twin wheel rim assembly is disclosed for use with an axle having a hub with an outwardly extending lip adjacent its inner end. The entire wheel assembly includes a pair of substantially identical wheels each having a rim with an outwardly flared portion as well as a tubular and cylindrical spacer. The wheels and the spacer are coaxially positioned over the hub so that the outwardly flared circumferential portion of one wheel abuts against the outwardly extending lip of the hub and so that the spacer is sandwiched in between the wheel rims. The wheel spacer is unable to slip because it has affixed to it evenly spaced ribs between each pair of wheel spokes. Both ends of each rib abut between each pair of wheel spokes. The ribs on the inside of the spacer is the primary element which prevents wheel slippage. This element in conjunction with the serrated edges will prevent wheel slippage.
