Abstract
An anti-abrasion and rockering system for an in-line skate. The skate includes a skate boot mounted on a chassis. The chassis includes two sidewalls which are parallel and opposite to each other. Each sidewall has a row of holes formed therein, such that the holes on the first sidewall align with and are opposite to the row of holes on the opposing sidewall. Two of the opposing sets of holes are oblong. A plurality of axles are disposed in the holes on the chassis so that the wheels are rotatably mounted on the axles and between the sidewalls of the chassis. The anti-abrasion and rockering system for the skate includes bushings disposed in the holes in the chassis. The bushings disposed in the oblong holes slide up and down in the holes. An anti-abrasion and rockering plate is disposed on the exterior of each sidewall. Each plate has a first and second row of holes for accommodating the axles. The first row of holes is misaligned so that some of the wheels on the skate are higher with respect to the skating surface than other wheel such that the front and rear wheels of the skate are rockered. The second row of holes is aligned so that all the wheels are at the same distance from t…
