Exercise device with elastic resistance

Abstract

Exercise system comprised of plurality of modular components enabling numerous types of exercises. Resistive force provided by durable elastomeric tubing that is quickly connectable to and disconnectable from more rigid components.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to physical conditioning and / or rehabilitation devices, and more particularly to devices including elastic and rigid components and exhibiting selectable resistive forces and secure mechanical links between the elastic and rigid components. BACKGROUND OF THE INVENTION [0002] More people engage in exercising as a leisure activity than any other type of activity. Portable exercise devices have become more popular because they are generally inexpensive to manufacture and are readily transportable so that a regular program of physical fitness can be maintained. [0003] One simple portable exercise device consists of a bar with a single elastic member three or four feet long and extending between the two ends so that a person could hold the bar and push down on the rope with his feet. A variation of this device consists of an elastic rope with two handles at the ends of the rope replacing the bar. [0004] The resistance ...

Benefits of technology

[0011] In one aspect described below, the invention provides a novel connection configuration employing an arrangement of cylindrical bushings, elastomer tubing (preferably latex), and a threaded member. The connection provides a very secure attachment between the tube and the metal parts that decrease the risk of disconnection and / or breakage present in some existing exercise systems. The threaded member may also include at one end a quick connector that allows modular components of the exercise system to be rapidly reconfigured without the use of pins or knots or the like.

Problems solved by technology

Such devices eventually fail to challenge a user as the user's strength increases.

Materials such as solid rubber may provide so much resistance that that they become difficult to stretch through the desired range of motion, and thus are not adaptable for use by a wide variety of users with different strengths and needs for exercise.

Other exercise devices enable an adjustable level of resistance, but typically are associated with a commensurate increase in cost and complexity.

Such devices may also require electrical power and occupy additional space.

Moreover, the devices may also require electrical power and are hazardous.

Another potential problem associated with this device is that it is difficult to eliminate the danger of injury from a handle that has broken off from the elastic rope during use.

In particular, difficulty exists in existing exercise devices in coupling the elastic member to the handles.
