Abstract
Abstract A dual action stationary exercise cycle providing independent upper and lower body exercising capability. The cycle, in one embodiment, provides a foot actuated lower body exercising apparatus including multi-sprocket, multi-chain, freewheel, flywheel resulting in a high ratio of flywheel rotation per pedal cranking. Also embraced in the lower body exercising device is an adjustable braking apparatus communicating with the flywheel to provide variable resistance to flywheel rotation which in turn varies the pedaling force required to propel the flywheel. The upper body exercising component of the cycle incorporates a handlebar assembly wherein the handlebar is rotatably connected to a stem and coacts with a variable resistance, piston-cylinder which imparts a force resistive to rotational movement of the handlebar in either the forward or the rearward direction or independently to both forward and rearward directions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
201 words
A dual action stationary exercise cycle comprising: a frame, a foot actuated exercising drive means mounted on said frame, a tubular member for supporting a seat thereon, means for height adjustably connecting said tubular seat supporting member to said frame, a handlebar assembly, said assembly including a mounting stem and a handlebar, said handlebar having a transverse medial segment and a pair of hand grips offset from said medial segment, means for pivotally connecting said handlebar at the medial segment thereof to said mounting stem, said pivotal connecting means including clamping means for rotatably securing said medial segment, means for height adjustably connecting said handlebar assembly to said frame, a variable resistance piston-cylinder, extension means interconnecting one end of said piston-cylinder and the medial segment of said handlebar, means for connecting the other end of said piston-cylinder to said mounting stem, said piston-cylinder coacting with said medial segment for providing resistance to pivotal movement of said handlebar, said drive means and said handlebar being in spaced and operatively disassociated relationship, whereby lower body exercise can be achieved by foot actuating said drive means while upper body exercise can be achieved, either simultaneously or independently, by pushing or pulling said hand grips.
