RECUMBENT STEP EXERCISER WITH SELF-CENTERING MECHANISM
A step exercise apparatus with a self-centering pedal system. The system comprising a frame and a seat supported from the frame. A first pedal assembly and a second pedal assembly are pivotally supported from the frame positioned so as to be manipulable by a user seated in the seat. A linkage is positioned in communication with the first pedal assembly and the second pedal assembly such that movement of either pedal assembly in a first direction causes movement of the other pedal assembly in a second direction opposite of the first direction. A brake is preferably employed for resisting motion of the first pedal assembly and the second pedal assembly in at least the first direction. A centering system positions the first and second pedal assemblies in a substantially central position when not being manipulated by the user.
1 . A step exercise apparatus comprising:
a frame;
a seat supported from said frame;
a first pedal assembly pivotally supported from said frame positioned so as to be manipulable by a user seated in said seat;
a second pedal assembly pivotally supported from said frame positioned so as to be manipulable by a user seated in said seat;
a linkage in communication with said first pedal and said second pedal assemblies such that movement of either pedal assembly in a first direction causes movement of the other pedal assembly in a second direction opposite of said first direction;
a brake for resisting motion of said first pedal assembly and said second pedal assembly in at least said first direction;
a centering system for positioning said first and second pedal assemblies in a substantially central position when not being manipulated by a user.
2 . The step exercise apparatus of claim 1 further comprising a seat adjustment mechanism such that said seat may be selectively moved forward or rearward to accommodate users of varying leg length.
3 . The step exercise apparatus of claim 1 wherein said brake is a generator.
4 . The step exercise apparatus of claim 1 wherein said centering system comprises a first spring in communication with said first pedal assembly and a second spring in communication with said second pedal assembly wherein forces applied by said first and second springs are equal when said first and second pedal assemblies are substantially centered.
5 . The step exercise apparatus of claim 2 wherein said seat is positioned relative to said first and second pedal assemblies so as to provide step-through space therebetween.
