ABSTRACT:
An in-line skate has a boot, a chassis supporting the boot, and a plurality of wheels rotatably mounted on axles supported by the chassis. An improvement of the in-line skate is a system for adjusting the height of at least one of the axles in relation to the chassis. The system includes a pair of opposed, coaxially rotatable bushings supported by the chassis. Each of the bushings defines a through-hole for passing a wheel axle. The axle-receiving through-holes are located eccentrically to the rotational axis of the bushings. The system also includes a pair of hubs where each of the hubs is interfitted with a different one of the rotatable bushings so that rotation of the hubs is transferred to equivalent rotation of the bushings. Like the bushings, each of the hubs defines a through-hole for passing the wheel axle. The hub through-holes are located eccentrically to the rotational axis of the hubs and the interfitted bushings. The system also includes a securing device coupled to the wheel axle for securing the bushings, hubs, and axle relative to the chassis. Also included is an actuator coupled to a first one of the hubs for receiving a force to rotate the first one of the hubs and the bushing interfitted therewith. A transferring device transfers rotation of the first one of the hubs and the bushing interfitted therewith (i) to rotation of the axle and (ii) to rotation of the other hub and the other bushing interfitted therewith. The system also includes a locking device, formed with the chassis, for releasably and replaceably cooperating with a portion of the actuator to secure the hubs and the bushings interfitted therewith against unwanted rotation.
