Abstract
An upper body exercise cycle comprising crank arms that may independently drive a flywheel, which provides resistance to the crank arms, an adjustable headstock and seat to accommodate users of different sizes and isolate different muscle groups, and a base plate ramp to provide support for the feet and to facilitate transportation of the upper body exercise cycle.
Claims20
An exercise equipment comprising:
- a. a base frame comprising a front portion and a rear portion;
- b. a flywheel rotatably connected to the base frame;
- and
- c. a crank assembly attached to the base frame, wherein the crank assembly comprises:
- i. a crankshaft housing;
- ii. a crankshaft housed inside the crankshaft housing;
- iii. a first and a second crank arm mounted on the crankshaft on opposite sides of the crankshaft housing;
- iv. a first and a second freewheel holder mounted on the crankshaft on opposite sides of the crankshaft housing and attached to the first and second crank arm, respectively;
- v. a first and a second freewheel mounted on the crankshaft on opposite sides of the crankshaft housing and coupled to the first and second freewheel holder, respectively, in a ratchet and pawl configuration to allow the first and second crank arms to drive the flywheel independently;
- vi. a chainring mounted on the crankshaft on one side of the crankshaft housing and fixedly attached to the second freewheel;
- and
- vii. a drive chain coupled to the chainring and the flywheel, wherein the first and second freewheels and the chainring are keyed to the crankshaft such that rotation of the crankshaft by the first or second crank arm in a first direction rotates the first or second freewheel, respectively, and the chainring, thereby allowing the first and second crank arms to independently turn the chainring to turn the drive chain and drive the flywheel.
