ABSTRACT:
A skate pole device can be used alone or in pairs by a roller skater in order to advance or retard movement along a skate surface. The skate pole has an elongated shaft with a handle portion on one end and a foot portion on the other end. First and second pads are mounted in the foot portion. The first pad is constructed of a type adapted to frictionally grip the skate surface so that the skater may exert a thrusting motion with the skate pole, and this material may be a stiff, yet resilient, rubber-like substance such as a soft thermoplastic. The second pad is constructed of a different type of material, such as a hard thermoplastic, that is adapted to act as a brake pad against the skate surface so that the skater may apply a drag force. A pair of such skate poles may be used and, if desired, interconnecting elements are provided to releasably secure two such skate poles alongside one another.
