  • Exercise device
    Patent number: 6013015
    Abstract: A thigh and buttocks exercising device includes a pair of hook shaped or curved clamp members terminating in linear inner legs connected to respective knuckles of a torsion spring-loaded hinge to bias the clamp members to a contracted position with their free ends in relatively vertically offset overlapping positions. Each clamp member is formed of a rigid metal tube preferably covered by a soft plastic or elastomeric sheath. The biasing torsion spring may terminate in tangentially projecting hook shaped cores of the clamp members. In alternative constructions, the clamp members are biased by resilient devices, such as a flexible-compressible member, a compression spring, or an elastomeric cord adjustably extending between the free ends of the clamp members.
    Type: Grant
