Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to exercise equipment, and more particularly relates to an exercise apparatus for strengthening a user's arms and legs.

[0003] 2. Description of the Related Art

[0004] Individuals in need of exercise often lack to the time to exercise at commercial gymnasiums and find it more convenient to exercise at home or while commuting. Standard exercise equipment is prohibitively large, expensive and cumbersome for home use. Many and varied types of compact exercise devices are available to help replace cumbersome gym equipment in home settings and assist individuals in their efforts to improve general strength, endurance and/or to mitigate specific health issues that need physical therapy.

[0005] The prior art includes complicated apparati comprising flexible rods, bungee cords, and inflatable or solid balls used for a large variety of conditioning activities including cardiovascular and spinal therapy, as well as increasing core strength, and strengthening in the upper and lower body muscles. Some exercise devices employ elastic resistance as a means of developing or measuring strength, but they are designed with a very limited exercises or muscle groups in mind, and are constrained by their own components and design to those limited areas. Certain muscles groups, such as the back and shoulder muscles, have very few simple portable devices designed for their exercise or strength measurement, due to the difficulties in designing a simple apparatus that can correctly resist the muscle motions leading to such development and measurement. Many patented portable devices that target difficult areas of the body to exercise such as these are complicated and difficult to find on the market.

[0006] There are no handheld devices in the art which target the muscles of a user's body and which can be rolled up and stowed in a space as compact as a drawer. Thus it would be highly beneficial to provide a simple, compact portable device that targets these muscles through a wide range of exercises, such as an adjustable elastic exercise chain.

SUMMARY OF THE INVENTION

[0007] From the foregoing discussion, it should be apparent that a need exists for an adjustable elastic resistance exercise device. Beneficially, such an exercise device would overcome many of the difficulties with prior art by providing a more functional apparatus to consumers.

Accordingly, the present invention has been developed to provide an isotonic exercise device comprising: a segment comprising a plurality of elastomeric rings affixed to one another in line, the plurality of elastomeric rings; wherein a diameter of each ring is between 1 inch and 10 inches; wherein each of the plurality of elastomeric rings is gripable by a user applying tensile force to the gripped ring.

[0009] The plurality of elastomeric rings may be formed as single integrated piece. In other embodiments, the plurality of rings in the segment are links interconnected forming a chain.

[0010] In still further embodiments, the isotonic exercise device further comprises one or more secondary segments of elastomeric rings detachably affixed to the segment to increase an overall length of the isotonic device.

[0011] The segment may comprise a plurality of single elastic ring(s) detachably affixed to one another by means of connectors. The isotonic exercise device may further comprise one or more handles detachably affixed to one of the plurality of elastomeric rings.

[0012] The handles may comprise elastic rings. The segment may be formed of a plurality of extruded elastomeric tubes helically wound around one another.

[0013] Each of the rings may be shaped as one of a torus, double torus, triple torus, toroidal polyhedron, dupin cyclide, and stretched donut-shape.

[0014] An isotonic exercise device is also disclosed comprising: a flexible elastomeric belt defining a plurality of apertures of between 1 inch and 10 inches in diameter; wherein the belt is graspable by a user through the apertures, the belt for applying tensile force to a user's hands.

[0015] In some embodiments, the isotonic exercise device may further comprise one or more handles detachably affixed to the belt, each of the one or more handles affixable to one of the apertures.

[0016] An isotonic exercise device is also disclosed comprising: a plurality of flexible elastomeric bands, each band comprising: a first connector affixed to a distal end of the band; and a second connector affixed to the proximal end of the band; wherein each band is detachably affixed to one or more bands from the plurality of elastomeric bands using one or more of the first connector and the second connector.

[0017] The isotonic exercise device may further comprise one or more handles detachably affixed to one of the plurality of flexible bands.
