1. A folding treadmill apparatus resting on a supporting surface, the apparatus comprising:
- a treadmill frame rotationally supporting spaced apart rollers in turn rotatingly engaging a treadmill belt for revolving around the rollers, the treadmill frame defining a treadmill frame plane;
a motor frame pivotally engaged with the treadmill frame, the motor frame defining a motor frame plane;
a drive motor fixed within the motor frame, the drive motor engaging one of said rollers thereby enabling motorized rotation of the treadmill belt;
an upright frame pivotally engaged with the motor frame, the upright frame providing means for resting on the supporting surface, the upright frame defining an upright frame plane;
a support strut pivotally engaged with the vertically disposed strut;
a sleeve pivotally engaged with the treadmill frame and slidingly engaged with the support strut;
an extender positioned and pivotally engaged within the apparatus so as to raise the treadmill frame over a range of angles with respect to the supporting surface thereby selectively setting an inclination of the treadmill belt;
the treadmill frame, motor frame, upright frame and the support strut rotatable about pivots enabling the planes of the treadmill frame, motor frame and upright frame to be positioned in essentially parallel juxtaposition.

Abstract
A treadmill frame rotationally supporting spaced apart rollers in turn rotatingly engaging a treadmill belt for revolving around the rollers and a motor frame pivotally engaged with the treadmill frame, the frame supporting a drive motor providing rotation of the treadmill belt. An upright frame in a simple rectangular shape with side struts pivotally engaged with the motor frame and a lower lateral struts positioned below the motor frame in a position for resting on a supporting surface. The treadmill frame, motor frame, upright frame and a support strut rotatable about pivots so as to set a treadmill inclination.
