Treadmill
First Claim
1. A treadmill comprising:
- a support frame including a base;
a base frame supported by the support frame and configured to pivot relative to the support frame about a first pivot line at a front end of the base frame;
a front roller and a rear roller rotatably supported by the base frame;
an endless belt disposed about the front and rear rollers, the front roller including an axle that defines an axis about which the front roller is rotatable;
an adjustment mechanism configured to adjust a position of the axle of the front roller relative to the base frame without changing the first pivot line;
the base frame pivots relative to the support frame about the first pivot line to move the base frame between a use position and a storage position; and
the base frame pivots relative to the support frame about the first pivot line to change an operational incline of the base frame.

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.

7. A treadmill comprising:
-
a support frame including a base; a base frame supported by the support frame and configured to pivot relative to the support frame about a first pivot line at a front end of the base frame; a front roller and a rear roller rotatably supported by the base frame; an endless belt disposed about the front and rear rollers, the front roller including an axle that defines an axis about which the front roller is rotatable; an adjustment mechanism configured to adjust a position of the axle of the front roller relative to the base frame without changing the first pivot line; a first bushing coupled to the base frame along the first pivot line, the first bushing configured to provide a pivot structure for the base frame; the first bushing includes an opening at one end configured to receive a first end of the axle of the front roller; the adjustment mechanism includes a threaded recess in the axle of the front roller and a threaded fastener configured to engage the threaded recess; and rotation of the threaded fastener adjusts the position of the axle of the front roller within the opening of the first bushing. - View Dependent Claims (8, 9)

15. A method of configuring a treadmill including a support frame having a base, a base frame supported by the support frame and configured to pivot relative to the support frame about a first pivot line at a front end of the base frame, a front roller and a rear roller rotatably supported by the base frame, and an endless belt disposed about the front and rear rollers, the front roller including an axle that defines an axis about which the front roller is rotatable, the method comprising:
-
adjusting a position of the axle of the front roller relative to the base frame without changing the first pivot line about which the base frame pivots; pivoting the base frame about the first pivot line relative to the support frame to change an operational incline of the base frame; and pivoting the base frame about the first pivot line relative to the support frame to move the base frame between a storage position and a use position.
