Abstract
A pedal powered exerciser including a pair of independent reciprocating push pedal drives. A pedal at each drive operates a chain trained between an idler axle and an independent live half axle. Inertial movement is sustained with a flywheel and overrunning clutch assembly at each live axle. Kinetic resistance at each live half axle can be selectively varied with a magnetic tension control assembly. A tubular framework supports the pedal slides, chains, flywheels, and magnetic tensioners. A pneumatic piston is hinged to self-adjust the angular orientation between main and base frames. A telescoping clamp assembly includes upper and lower jaws that are adapted to mount to a recliner footrest. The clamp assembly is longitudinally adjustable and detachable from a receiver to permit transport.
Claims17
Exercise apparatus comprising:
- a) a base frame having a plurality of support feet;
- b) an elongated main frame mounted to pivot from said base frame and including 1) first and second pedals mounted for reciprocating movement along said main frame;
- 2) an idler axle mounted to said main frame;
- 3) first and second drive axles mounted to said main frame;
- 4) means for coupling said first and second pedals to first and second chains respectively trained between said idler axle and said first drive axle and said idler axle and said second drive axle;
- 5) first and second flywheel means mounted to said first and second drive axles to each rotate independent of the other and only in response to movement of each of said first and second drive chains in a first direction;
- and
- c) coupler means for coupling said main frame to a chair, whereby a user can exercise the legs while seated.
Exercise apparatus comprising:
- a) a base frame including a plurality of support feet;
- b) an elongated main frame including 1) first and second pedals mounted for reciprocating movement along first and second rails of said main frame;
- 2) an idler axle mounted between said first and second rails;
- 3) first and second drive axles respectively mounted to said first and second rails;
- 4) means coupling said first and second pedals to first and second chains respectively trained between said idler axle and said first drive axle,and said idler axle and said second drive axle;
- 5) first and second flywheels mounted to said first and second drive axles to each rotate independent of the other and only in response to movement of said first and second drive chains in a first direction;
- c) piston means mounted between said main frame and said base frame for biasing a pivoting movement between said main frame and said base frame;
- and
- d) coupler means for coupling said main frame to a chair, whereby a user can exercise the legs while seated.
