Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
In combination with an in line skate having a boot, a frame supporting the boot, and a plurality of wheels rotatably mounted on axles supported by the frame, the improvement of a system for adjusting the height of at least one of the axles in relation to the frame, the system comprising a pair of opposed, coaxially rotatable bushings supported by the frame and each defining a through hole for passing the ends of a wheel axle, the axle-receiving through holes being located eccentrically to the bushings' rotational axis, securing means coupled to the wheel axle for securing the bushings and axle relative to the frame, a lever extending radially outwardly form each of the rotatable bushings for receiving a force to rotate the bushings, and locking means, formed with the frame, for releasably and replaceably receiving a portion of each of the levers to secure the bushings against unwanted rotation.
