First Claim
1. 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;
(i) a roller mounted on an axle, the axle including a threaded recess being seated in at least one bushing, the bushing forming an axle extension and being disposed between the motor frame and the base frame to allow the motor and base frames to rotate relative to one another,(ii) a threaded fastener extending through the bushing into the threaded recess of the axle, the threaded fastener being adapted to adjust the position of the roller by engaging with the threaded recess of the axle,(iii) a support bed, and(iv) a belt extending over the support bed and adapted to be driven by the roller;
wherein the axle is seated in a second bushing, and the belt urges the axle into the second bushing.

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.
