Abstract:
1. An exercise device comprising (a) a frame defining a transverse axis, (b) first and second foot supports operably associated with the frame for traveling along a closed loop path relative to the transverse axis wherein the closed loop path defines a stride length, (c) a means effective for sensing the speed of travel of the foot supports along the closed loop path, (d) a means for automatically adjusting the stride length of the closed loop path traveled by the foot supports based upon the sensed speed of travel of the foot supports, (e) a guide arm pivotally attached to the frame, (f) a transversely extending drive shaft rotatably attached to the frame and extending along the transverse axis, (g) an extension element extending away from the transverse axis and fixedly attached to the drive shaft for unitary rotation with the drive shaft, and (h) first and second foot links each supporting a foot support and having (i) first and second ends, (ii) a first end portion pivotally attached to the extension element at a point spaced from the transverse axis for travel alone a closed loop path relative to the transverse axis, and (iii) a second end portion pivotally supported by the guide arm for longitudinal travel of the second end portion of the foot link along an arcuate reciprocating path.
