Abstract

An exercise device including two foot platforms riding on elongated rails for longitudinal motion relative thereto. The platforms are directly connected to each other by one or more elastic elements. One or more dampers are installed substantially parallel with the elastic elements to oppose the energy return of the elastic elements. When the two platforms are side-by-side, the elastic elements and dampers run in a substantially crosswise direction. A seated user may place feet on the platforms and move his/her feet and lower legs back and forth in a scissoring motion to move the platforms in opposition directions along the rails. In so doing, the user overcomes the resistance of the elastic elements and dampers connecting the platforms. This provides the user with exercise and its accompanying benefits.

Claims28

Dependent claims

An oscillating exercise device comprising:

a rigid frame extending in a longitudinal direction, and defining a pair of adjacent and longitudinally-extending raceways;
a pair of platforms supported on the frame, each of said pair of platforms being supported for translational movement within a respective one of said pair of raceways;
at least one resilient member having first and second ends, the first end being joined to one of said pair of platforms, and the second end being joined to the other of said pair of platforms to resist translational movement of said pair of platforms, said at least one resilient member being stretched taut to extend linearly between said pair of platforms, said at least one elastic resilient member biasing said pair of platforms toward a neutral position in which said at least one elastic resilient member is minimally stretched;
and
at least one damper having first and second ends, the first end being joined to one of said pair of platforms, the second end being joined to the other of said pair of platforms to resist resiling of said resilient member;
whereby forcible movement of said platforms of said pair of platforms in opposite directions further stretches said at least one resilient member, said at least one resilient member resisting such movement in opposite directions.
