FIGS. 1 to 3 of the drawings illustrate the structure of a stair climbing exercise machine 10 according to a preferred embodiment of the present invention, while FIGS. 4 to 6 illustrate the control system for controlling and monitoring operation of the machine.
Due to its hydraulic operation, this stair climbing exercise machine is both quiet and reliable. The independent pedal operation mimics standard stair climbing more accurately than dependent pedal operated machines.
According to the present invention, a stair climbing exercise machine is provided, which comprises an upright frame, a pair of right and left pedals pivotally mounted on the frame for independent movement between raised and lowered positions, and a hydraulic control assembly for resisting downward movement of each pedal independent of movement of the other pedal and for returning each lowered pedal to a raised position on removal of weight from that pedal.
Exercise machines which simulate stair climbing types of exercise are relatively well known in the exercising field. For example, U.S. Pat. No. 4,708,338 of Potts describes such an apparatus in which right and left pedals are pivotally mounted on a frame. The user depresses alternate pedals against the action of a spring in a fashion similar to that used in climbing stairs. A monitoring system monitors the work performed by the user and displays that information on a screen mounted at an appropriate height on the frame, in the form of an LED graphical display. Other stair climbing exercise machines are described in U.S. Pat. Nos. 4,496,147 of DeCloux, et al., 4,676,501 of Hoagland, et al., and 3,970,302 of McFee.
