Abstract
An articulating treadmill is disclosed that includes a support frame, a motor frame, and a base frame. The motor frame is pivotally attached to the support frame along a first pivot line, and the base frame is pivotally attached to motor frame along a second pivot line spaced from the first pivot line. The base frame pivots about the second pivot line from an unfolded configuration to a folded configuration, and vice versa. The treadmill includes an elevation motor having an extension arm. The elevation motor is attached between the motor frame and a base of the support frame. As the extension arm of the elevation motor extends or retracts, the incline of the treadmill support bed increases or decreases, respectively. The treadmill also includes an adjustable roller system.

A treadmill comprising:
- (a) a support frame having a base;
- (b) a motor frame pivotally attached to the support frame at along a first pivot line;
- (c) a base frame having a support bed, the base frame being pivotally attached to the motor frame at along a second pivot line spaced from the first pivot line;
- and
- (d) an elevation motor having an extension arm, the elevation motor being attached to the motor frame and to the base of the support frame,
- wherein as the extension arm extends, an incline of the support bed of the base frame changes.
A treadmill comprising:
- (a) a support frame having a base;
- (b) a motor frame attached to the support frame along a first pivot line;
- and
- (c) a base frame attached to the motor frame, the base frame having:
