Vibrating dumbbell has electric motor with flyweights in its tube, to generate vibrations to aid healing and pain relief

摘要

The dumbbell consists of a tube (1) with additional weights (6) at both ends. The tube can be vibrated, and the weights are uncoupled from the tube for vibrations. Uncoupling is via spring steel wires between steel rings (2,3), almost without dampening. Wires and rings are connected non-sliding and non-turning, and are of suitable thickness and length to achieve set spring constant, e.g. 360[deg] constant. Additional weights of different mass may be fitted to the steel rings. The tube contains an electric motor (4) with flyweights (5) on its shaft ends, which is supplied by a battery or externally.
