ABSTRACT:
The present invention involves a skate that can be converted from an in-line wheel configuration in which all of the skate wheels are coplanar to a parallel or quad wheel configuration, and vice versa. The skate includes a foot or shoe enclosure, a wheel chassis, a wheel support, at least two wheels, and a tie rod which anchors the wheel chassis at a center point and allows the wheel chassis to pivot the wheels from an in-line to a parallel configuration. The foot enclosure includes posts which support and secure the wheel chassis, with a nut threadably engaging the post to rotatably secure the wheel chassis relative to the foot enclosure. The tie rods have a predetermined length which maintains the angular position of the wheels relative to the foot enclosure regardless of the angular position of the wheel chassis.
