ABSTRACT:
An incline adjustment mechanism for use with exercise apparatus such as treadmills is disclosed. The mechanism includes a support or foot assembly rotatably mounted to the bottom surface of the treadmill frame. One or more springs are interposed between the treadmill frame and the support assembly for urging them outwardly from each other. A perforated strip mounted on the support assembly extends upwardly into proximity of the frame. A displaceable plunger shaft configured to be received within the apertures of the strip and form a union with that strip is mounted on the frame. The plunger is adapted to engage the strip and form a union therewith, thereby locking the support in an orientation which supports the treadmill at a selected orientation.
