Abstract

Abstract A two wheel roller skate including a shoe having a sole, a front wheel carried on a front axle and a rear wheel carried on a rear axle. The skate includes a pair of axle forks each of the axle forks having opposed side portions which receive the axle, and a transverse portion which interconnects the side portion at one end of the axle forks. Each axle fork side portion includes a generally inclined portion engageable with the shoe sole and a generally horizontal portion connected to the transverse portion. The sole includes opposed side slots which receive the unconnected ends of the side portions and a fastener attaches the transverse portion of the axle forks to the sole, the axle fork side portions and the transverse portion fastener providing a three-point connected to the roller skate. The axle forks can be readily connected and disconnected from the shoe sole for replacement of the wheels with wheels having a rounded bearing surface.
