US 7,621,850 B2 · Dual deck exercise device

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.

Dependent claims

An exercise machine, comprising:

a frame;
a first treadle having a belt, a treadle frame, and a set of three rollers defining a triangular shape, the belt positioned about the set of rollers;
a second treadle having a belt, a treadle frame, and a set of three rollers defining a triangular shape, the belt positioned about the set of rollers;
and
means for pivotally coupling the first and second treadles to the frame at a location respectively between ends of treadle surfaces defined by the first and second treadles such that the first and second treadles are supported to pivot relative to the frame near respective rear ends whereby a user can step or stride on the treadles.
