Abstract: A wheel lock assembly for an in-line skate includes an axle assembly for supporting a skate wheel and defining an enclosed cavity, and an actuator assembly comprising an actuator member disposed in the cavity movable by a control member disposed externally of the axle assembly. The lock assembly further includes a lock pad assembly comprising a lock pad adapted to engage an inside surface of the skate wheel mounted on the axle assembly, a support beam extending from the pad inwardly through a portion of the axle assembly and into the cavity, and a spring urging the lock pad and support inwardly to bias a free end of the support against the actuator member. Manipulation of the control member causes movement of the actuator member in the cavity, to cause movement of the support, to cause radial movement of the lock pad selectively into and out of engagement with the skate wheel inside surface.
