US Patent 7246803 Tool-less size-adjustable in-line skate

A size-adjustable in-line skate having a base carrying a plurality of wheels thereon. An upper is secured to a top surface of the base and defines a heel portion, a toe portion, and diametrically opposed side wall portions. The upper is supported by a support structure that includes a heel cup and a toe cup. The toe cup is secured to the toe portion of the upper and slideably coupled to the base so that the toe cup can slide longitudinally with respect to the base. An actuator is coupled to the toe cup and travels therewith. When the actuator is translated, engagement members on the actuator disengage with detents on the base to allow the toe cup to freely slide between longitudinal positions to adjust the shoe size of the skate.
