ABSTRACT:
An axle for in-line roller wheels allowing quick release of the wheels and axle from the in-line skate blade frame. The axle is constructed and arranged to allow the distal ends of the axle to move longitudinally relative to each other. There is a spring or other such mechanism forcing the ends of the axle into the openings in the blade frame. The ends of the axle that protrude into the frame are designed not to protrude beyond the outer sides of the frame structure so that the ends of the axle are not subject to wear. The present invention provides for an in-line skate axle that is secure and never needs tightening. Since the wheels are retained by springs there are no bolts or threaded connections to become loose. Other types of construction retain the axle and wheel in the blade frame using spring forces in tension rather than compression. In such arrangements the spring is stretched through the axle and the end retainers are pulled into place thereby retaining the axle and wheel to the frame. Other such arrangements such as bayonet type retaining locks may be used to advantage in the present invention.
