Dual deck exercise device
First Claim
1. An exercise device comprising:
- a first treadle operably mounted on a frame to pivot with respect to said frame;
a first resistance element operably mounted between said frame and said first treadle, said first resistance element having a mounting position that is selectively movable within a range of mounting positions via an adjustment structure to adjust a position of said first treadle with respect to said frame; and
for each mounting position of said first resistance element within the range of mounting positions, at least a substantial portion of the first resistance element is located at an elevation that is lower than said first treadle and at least a substantial portion of said adjustment structure is located at an elevation that is lower than the first resistance element.

Abstract
An exercise device employing side-by-side pivotally supported moving surfaces. In one particular example, an exercise device employs a first belt deployed about a front roller and a rear roller and an adjacent second belt deployed about a front roller and a rear roller. The rear of the belts in the area of the rear rollers are pivotally secured and the front of the belts in the area of the front roller are adapted to reciprocate in an up and down motion during use. In some implementations, the moving surfaces include an interconnection structure such that a generally downward movement of one surface is coordinated with a generally upward movement of the other surface. In other implementations, the moving surfaces are operably associated with one or more resistance elements that effect the amount of force required to pivot or actuate the moving surfaces.

9. An exercise device comprising:
-
a frame, said frame having a range of attachment locations; a first treadle pivotally mounted to said frame to pivot in a generally vertical plane; a first resistance device having a top end and a bottom end, said top end of said first resistance element being operably attached to said first treadle, and said bottom end of said first resistance element being adjustably attached to said frame at a first location within said range of attachment locations; wherein adjustment of said bottom end of said first resistance element to a different location within said range of attachment locations changes a height of said first treadle; wherein said first resistance element is attached to said frame by a lead screw mechanism; and for each mounting position of said first resistance element within the range of mounting positions, at least a substantial portion of the first resistance element is located at an elevation that is lower than said first treadle and at least a substantial portion of said lead screw mechanism is located at an elevation that is lower than the first resistance element. - View Dependent Claims (10, 11, 12)
