Exercise treadmill
First Claim
1. A treadmill, comprising:
- a frame having a first side rail and a second side rail, wherein said second side rail is oppositely disposed from said first side rail;
a front roller and a rear roller operatively connected to said frame;
a deck operatively connected to said frame;
a belt trained around said front roller and said rear roller;
a first belt tensioning mechanism, comprising;
a first rod operatively connected to one side of said belt;
first protrusion means for turning said first rod; and
,a first visual indicator adapted to track the number of revolutions of said first rod;
a second belt tensioning mechanism comprising;
a second rod operatively connected to the opposite side of said belt;
second protrusion means for turning said second rod; and
,a second visual indicator adapted to track the number of revolutions of said second rod;
wherein each of said rear rollers has an axle passing though a longitudinal axis, said axle having first and second ends, said first end and said second end having a hole defined therein, wherein said first protrusion means and said second protrusion means each comprising a knob having said rod extending therefrom, said rod adapted to pass through said respective holes of said axle such that rotation of said first rod moves said first end of said axle, said first visual indicator further comprises indicia; and
an indication member adapted to move relative to said indicia, said indication member operatively connected to said first end of said axle.

Abstract
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.
