Abstract
A dual action cycle exerciser providing for exercising movement of the arms and legs using rotating pedals and oscillating handlebar levers. Connecting rods linking the handlebar levers and the pedals are journalled about the pedal axes via upwardly projecting rigid portions, resulting in a simplified construction affording beneficial exercise results, improved access to the seat of the cycle exerciser, and easier initiation of exercise movement.
Claims3
A cycle exerciser comprising:
- a frame;
- a transverse drive shaft journalled on said frame;
- a pair of cranks respectively secured 180 degrees out of phase to opposite ends of said drive shaft so as to rotate therewith;
- a foot pedal attached to the outboard side of each of said cranks and rotatable thereon about a transverse pedal axis;
- a pair of oscillating handlebar levers pivotally mounted on said frame intermediate their ends ahead of said drive shaft for fore and aft movement on opposite sides of said frame;
- a handle at the upper end of each of said handlebar levers;
- a seat mounted on said frame above and aft of said drive shaft to position a user within reach of said foot pedals and said handles;
- a pair of connecting rods at opposite sides of said frame, each connecting rod pivoted at its forward end to the lower end of the respective handlebar lever, and having at its rear end a rigidly attached upwardly projecting portion which is pivoted to the respective crank about the respective pedal axis, whereby rotation of said pedals and oscillation of said handlebar levers are synchronized and said connecting rods are located below said pedals throughout their revolution about said drive shaft;
- and
- energy absorbing means on said frame operatively connected to said drive shaft for resisting rotation of said drive shaft caused by the user's rotation of said pedals and/or oscillation of said handlebar levers.
