Exercise bicycle

Claim 1

An exerciser comprising: a frame; a saddle fixed to said frame; a loading means acting upon a fly wheel rotatably mounted on said frame and outer periphery of said fly wheel for exerting load thereon which includes a roller which is pressed to an elastic body forming said outer periphery of said fly wheel for exerting load on said fly wheel, a bearing rotatably supporting said roller, a conductor disc connected to said roller by a shaft common thereto and at least one pair of magnets each disposed immediately adjacent to both surfaces of said conductor disc in a manner to interpose said conductor disc therebetween, and utilizes eddy currents generated by the rotation of said conductor disc for loading on said flywheel; a pedal shaft which is rotatably mounted to said frame and is coupled to be rotated by pedal cranks to which respective pedals are fixed; an intermediate shaft which is rotatably mounted to said frame and is coupled to a pair of cranks extending in the opposite axial directions thereof at the right and left sides of said frame, respectively; a pair of handle bars each pivotally mounted to the lower front part of said frame at the right and left sides of one end of said frame and, a rotation transmitting means provided with a one-way clutch for transmitting only one directional rotation of said pedal shaft to said intermediate shaft; a pair of levers connected by one end thereof to opposite end of said intermediate shaft with different relative angular positions, respectively, a pair of connection rods for pivotally connecting an intermediate part of said handle bars and the other ends of said levers, so that the swing motion of the handle bars is transmitted to said intermediate shaft and converted into the rotational movement of said intermediate shaft, and further into rotation of said flywheel.
