A lifting mechanism and treadmill arrangement is constructed to include a base frame having a horizontal guide frame, a treadmill base, two links bilaterally mounted on the base frame, and a lifting mechanism mounted between a front side of the treadbase and the base frame and having a push member and an inclining motor controlled to drive the push member to move back and forth along the guide frame so as to adjust the angle of inclination of the treadbase.
The present invention relates to an inclining treadmill having a hood assembly pivotally coupled between the frame and the inclining tread base of the treadmill. The configuration of the pivoting hood assembly allows the inclining tread base to incline to a grade of at least 20 percent. The pivot point of the pivoting hood assembly is positioned distally from the distal end of the tread base. The pivoting hood assembly is positioned at an angle to greater than 40 degrees when the tread base is at its greatest grade of incline. A lift motor engages a channel bracket assembly of the pivoting hood assembly at a point distal to the pivot point of the pivoting hood assembly. The inclining tread base is linked to the frame of the treadmill by being coupled to the pivoting hood assembly.
An improved lift apparatus for use in a treadmill having a support base and a treadbase is disclosed. The lift apparatus includes a lift motor assembly linked to the support base and to a cam. The first cam can be attached to a torsion bar linked to the support base. An incline link bar is linked to the first cam and to the treadbase. The force generated by the motor assembly is efficiently translated from the cam to the treadbase, thereby inclining the treadbase.
