Abstract
Abstract A hopping roller skate comprises a hopping shoe, which comprises a shoe and a pair of coil springs with or without an elastic base plate, combined with a fixed or releasable roller skate body, and is used for the training of skiing or cross-country skiing. When separated the hopping shoe and roller skate may each function in their usual and ordinary manner, respectively. The arrangement of the rollers under the skate body may be selected in accordance with the desired training for the sport. Stability for a wearer on the coil springs is maintained with a pair of sticks. The extreme outer coils of the springs arranged outwardly on the roller skate are at a right angle to a respective longitudinal axis. The sticks and the coil springs accelerate the sliding speed of the skate by their stroke or thrust movement, and change the sliding direction in the same manner as an ordinary ski. Front and rear brakes control the movement and sliding speed by contact friction with the ground.
