Abstract:
1. A self-powered exercise apparatus for providing a resistive force against the ambulatory motion of a user, the exercise apparatus comprising: (a) a support frame; (b) a rotatable shaft supported and fixed to the frame at one or more rotation bearings; (c) a spool assembly having a center fixed on the rotatable shaft and comprising a winding drum; (d) a length of lead line windable on the spool assembly, the length of lead line sufficient to allow the user to engage in said ambulatory motion for a plurality of strides away from the spool assembly; (e) a flywheel assembly having a center fixed on the rotatable shaft, the flywheel assembly having a flywheel rotatable in conjunction with the rotatable shaft, and wherein drawing the length of lead line out from being wound on the spool assembly directs a first rotational motion of the rotatable shaft and the flywheel assembly; and (f) a resistance adjustment assembly in sliding frictional contact with a perimeter rim of the flywheel, the resistance adjustment assembly fixed on the support frame adjacent the flywheel assembly, the resistance adjustment assembly comprising: an adjustment knob having a movable contact point; a brake lever arm in contact with the movable contact point on the adjustment knob; and a brake pad pivotally positioned on the brake lever arm and oriented for contact with the flywheel; wherein drawing the length of lead line out from being wound on the spool assembly directs a first rotational motion of the rotatable shaft, and wherein releasing the length of lead line drawn out from the spool assembly allows for a second rotational motion opposite the first in a manner that rewinds the length of lead line on the spool assembly.
