An exercise treadmill (20) is described having a number of assembly improvements. In one embodiment, a pivot assembly (50) is provided to allow a treadmill deck (32) to deflect during use. The rear pivot assembly includes a pin (56) transversely mounted on the upper surface of a treadmill frame (22). A pivot block (54) is attached to the deck and includes a lower channel (58) that engages the pin. In another embodiment, an adjustable rear foot assembly (70) is provided having a foot (74) that is rotatable within a mounting block (72). The foot is easily accessed through an upper opening (96) in the treadmill. In yet another embodiment, an air dam (100) is provided between a motor compartment (102) and an adjacent endless belt (28). In still another embodiment, a highly elastic drivebelt (120) is used between a motor assembly (104) and a roller assembly (24) that drives the endless belt (28). Lastly, an embodiment is described in which the treadmill frame (22) is assembled using swaged fasteners (38).
RELATED U.S. APPLICATION DATA
The present application is a division of U.S. patent application Ser. No. 10/187,054, entitled "Adjustable Exercise Device," filed on Jun. 28, 2002 by Dyer et al, now abandoned.
A new and improved exercise treadmill may include a frame having a first end and a second end, wherein the second end is parallel to the first end. Two sidewalls interconnect the first and second end. The treadmill may further comprise a motor in order to drive a belt, which is trained over a front roller and a rear roller. A deck is positioned underneath the belt in order to support the user. The treadmill may also comprise a belt tensioning device, which provides a visual indicator so that the rear roller may be moved on each end in equal distance relative to the front roller. Another feature of the invention is a slot between the side rails and the frame so that an extended member can be inserted therein to lubricate the belt.
