Abstract
An in-line roller skate utilizes dual position, eccentric axle aperture plugs which are received in the axle apertures of the skate frame to allow mounting of the skate's wheels in either of two distinct orientations. The plugs also solve a serious assembly problem by allowing wheels to be installed in the skate frame without the alignment problems previously encountered between frames, wheels and hard to handle spacing washers.
