Abstract
Abstract A versatile exercise device designed particularly for running in place, against the restraining force of an anchored belt, includes a single piece of rope, one end of which is arranged for anchorage to a fixed object, and the other end of which is formed into an adjustable belt by a simple and convenient loop forming device.

Claim 1
Independent Claim
206 words
A device for running in place exercises comprising: a flexible and essentially inextensible unitary tension rope rope of which one end is formed into a loop within which a person can exert a forward thrust on the loop, the tension rope having at its one end a holding device for removably affixing it to a fixed object for resisting tension, the free end of the loop portion of the rope being immovably but adjustably fastened to the standing part of the rope at the other end of the loop, the standing part of the rope extending beyond and away from the loop for a length sufficient to pass around a fixed object for resisting tension, the end of the rope having an enlargement, and a portion of the rope close to the enlargement lying in parallel contact with the standing portion of the rope, and a rigid helix of at least one and one half turns having a pitch resulting in a spacing between turns slightly greater than the rope diameter and an internal diameter slightly greater than twice the rope diameter, said helix surrounds the two adjacent portions of the loop portion of the rope and holds the rope against separation from a fixed object.
