Abstract
A roller skate includes a chassis having a first frame and a second frame extending longitudinally parallel to each other, first through fourth wheels rotatably mounted in spaced apart manner between the first and second frames, and first through fourth slots provided in spaced apart manner in each frame. The first slot is positioned adjacent a front end of the frame and the fourth slot is positioned adjacent a rear end of the frame. The first through fourth wheels are mounted adjacent the first through fourth slots, respectively, of both frames. The center of the fourth slot is positioned at a vertical level higher than the center of the first slot.
