ABSTRACT:
A self-propelled roller skate requiring a minimum of energy of the wearer thereof includes an articulated frame having a front portion, which includes the propelling mechanism, and a rear portion, which includes a standing and braking apparatus. The propulsion of the roller skate is accomplished by the wearing individual merely raising the front portion of his foot and shifting his body weight to the heel of the same foot or to the opposite foot. Upon placing the raised foot or portion upon a flat surface and shifting his weight back to that foot or portion, propulsion is accomplished without requiring any additional physical energy.
