ABSTRACT:
One or both ends of a skateboard has its effective lower surface of the platform brought nearer to the ground than the remainder of the platform by the addition of a block or blocks which comes into contact with the ground when the rider elects to ride the skateboard on only one of the two sets of wheels. The existence and shaping of this block assists the rider to maneuver and control the board and avoids the wear of an irreplaceable part of the board. The block is moulded plate of suitable material attached to the underside of the board the major opposing sides of the plate being elliptical. For control purposes the shape over a 120.degree. central sector of the major side is significant but for wear factor reasons it is extended to 160.degree.. No part of the radius should be less than 15 mm, or more than 110 mm. and the contact periphery should have a rounded shoulder to provide a satisfactory area of initial contact. The unexposed face may have a grid of holes to assist cooling, trap melting material, and reduce weight, or they may be filled with inserts of harder material to resist wear.
