BACKGROUND OF THE INVENTION

[0004] 1. Field of the Invention

[0005] The present invention relates generally to an exercising apparatus and more particularly to a compact, multi-purpose exercise device for accomplishing a number of progressive resistance-type exercises using a novel elastomeric cord-resistance unit which provides a variable resistance to the performance of the exercises.

[0006] 2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 1.98

[0007] The therapeutic value of progressive resistance exercises has long been recognized. Exercising muscles against progressively increasing resistance not only results in added strength and endurance in the muscles, but also in the improvement of neuromuscular coordination and in a more efficient functioning of the cardiovascular and respiratory systems.

[0008] In the past, various types of progressive weight training machines have been suggested. Typically, the prior art exercise apparatus uses one or more weights selected from a stack of weights to provide gravity resistance to the movement of a carriage or other body engaging means. Such apparatus inherently very heavy and not well suited for use in certain facilities. Additionally, the prior art apparatus is typically quite bulky and difficult to use in confined areas having limited ceiling heights. Further, the weight and bulk of the prior art devices makes their storage and transport quite difficult.

[0009] The apparatus of the present invention overcomes many of the drawbacks of the prior art exercise devices by providing an apparatus that is compact, lightweight, and readily usable in confined areas. The apparatus includes a non-gravity selectorized resistance module that is made up of a plurality of elastomeric cords which offer variable resistance to the trainee.

BRIEF SUMMARY OF THE INVENTION

[0010] It is an object of the present invention to provide an improved, non-gravity type resistance exercise apparatus which is small, lightweight, and easy to use. More particularly, it is an object of the invention to provide an exercising device that includes a plurality of elastomeric cords which can be quickly and easily selectively coupled with the body engaging member to provide precise resistance to the performance of several different kinds of exercises.

[0011] Another object of the invention is to provide an apparatus of the aforementioned character which includes a mechanism for selectively interconnecting the body engaging member with the selected resistance imparting cords of the apparatus. The elastomeric cords can be selected so that a wide range of effective resistance can readily be achieved.

[0012] Another object of the invention is to provide an apparatus of the character described that includes novel connector elements that permit the apparatus to be connected to the seat of a chair so that exercises can be performed with the trainee sitting in the chair.

[0013] Still another object of the invention is to provide a compact, lightweight exercise apparatus that is both safe and reliable, while at the same time providing a full range of movement when performing exercises.

[0014] Another object of the invention is to provide a device as described in the preceding paragraphs that embodies a minimum number of component parts and one which is easily operable with a minimum of instruction.

DETAILED DESCRIPTION OF THE INVENTION

[0021] Referring to the drawings and particularly to FIG. 1, one form of the exercise apparatus of the invention is there shown and generally designated by the numeral 14. Apparatus 14 here comprises a base assembly 16 that includes a central portion 18 and a pair of spaced apart foot engaging members 20 that are pivotally connected to the central portion for movement between the normal extended position and the stowed position shown by the dotted lines in FIG. 1. Also pivotally connected to central portion 18 of the base assembly is an elongate strut 22. Strut 22 has a first end 22a that is pivotally connected to the central portion of the base assembly (see FIG. 4), an intermediate portion 22b and a second end 22c that is spaced apart from first end 22a. Connected to connector strut 22 proximate first end 22a is a hub-like first guide member 24. For a reason presently to be described, the intermediate portion of the strut 22 is provided with a plurality of spaced apart apertures 26.

[0022] Also forming a part of the exercise apparatus of the invention is an elongate body engaging member 28 that is movable by the trainee between a first position shown in FIG. 1 and a second position shown in FIG. 4. Body engaging member 28 has a first end 28a, a second end 28b and an intermediate portion 28c. As shown in FIG. 1, the second end 22c of the connector strut 22 is pivotally connected to the intermediate portion 28c of the body engaging member. For a reason presently to be described, the intermediate portion of the body engaging member is also provided with a plurality of spaced apart apertures 30. Connected to body engaging member 28 proximate its first end 28a is a second hub-like guide member 32 and removably connected to body engaging member 28 proximate its second end 28b is a pair of spaced apart handgrips 31 (see also FIG. 3A).

Forming an important part of the exercise apparatus of the invention is a resistance means that functions to yieldably resist movement of the body engaging member from the first position to the second position. This important resistance means here comprises a pair of stretchable members 34 that interconnect the body engaging member 28 with the connector strut 22. Stretchable members 34, which here comprise elongated elastomeric cords, are entrained about the first and second guide members 24 and 32 in the manner illustrated in FIG. 1 of the drawings. As best seen in FIG. 1, each of the stretchable members 34 has a first end 34a that is provided with a hook-like member 42 and a second end 34b that is provided with a hook-like member 44. It is to be understood that the elastomeric cords can be selected so that a wide range of effective resistance can readily be achieved.

[0023] Connected to elongate body engaging member 28 for slidable movement between the first and second positions is a first selector assembly 36. Selector assembly 36 here includes a box-like body 38 that includes a sleeve portion 38a that circumscribes the body engaging member and a pair of connector toggles 40 that are operable by the trainee to permit the pin portions 40a of the toggles to be removed from a selected one of the apertures 30 provided in the body engaging member (see arrows 41) so as to permit the selector assembly to be moved along the body engaging member from a first position shown by the solid lines in FIG. 1 to a second position shown by the phantom lines in FIG. 1. Selector assembly 36 also includes a pair of outwardly extending connector elements 43 to which end 42 of each of the stretchable members 34 is connected. As illustrated in FIG. 1, the second end 44 of each of the stretchable members 34 is connected to a second selector assembly 46 that is slidably movable along connector strut 22. Second selector assembly 46, which is of a substantially identical construction to first selector assembly 36, includes a box-like body 48 that includes a sleeve portion 48a that circumscribes the connector strut 22 and a pair of connector toggles 50 that are operable by the trainee to permit the pin portions of the toggles (not shown) to be removed from a selected one of the apertures 26 provided in the connector strut 22 so as to permit the selector assembly to be moved along the connector strut.

[0024] By moving the first selector assembly 36 along elongate body engaging member 28 so as to stretch, or relax the stretchable members 34, the resistance offered by the stretchable members to movement of the body engaging member 28 can be controllably varied. Alternatively, by moving the second selector assembly 46 along connector strut 22 so as to stretch, or relax the stretchable members 34, the resistance offered by the stretchable members to movement of the body engaging member 28 can also be controllably varied.

[0025] As illustrated in FIGS. 1, 3 and 5, base assembly 16 further includes two pairs of chair engaging members 54 that are pivotally connected to the central portion 18 of the base assembly 16 for movement between the stowed position shown in FIG. 1 to the extended position shown in FIGS. 3 and 5, wherein the exercise apparatus can be connected to the seat of a chair. With the chair engaging members 54 extended, they can be positioned over the chair seat in the manner shown in FIGS. 3 and 5 so that the apparatus can be removably connected to the chair seat. With the trainee seated in the chair in the manner shown in FIG. 5, the trainee can perform several different resistance exercises. For example, by gripping the hand grips 31, the elongate body engaging member 28 can be moved against the resistance of the stretchable members 34 between the first position shown by the phantom lines in FIG. 5 and the second position shown by the solid lines.

[0026] As illustrated in FIG. 4, similar resistance exercises can be performed by the trainee when the spaced apart foot engaging members 20 are positioned on the floor "F". In this instance, the trainee steps on the foot engaging members, grips the hand grips 31 and pulls the elongate body engaging member 28 against the resistance of the stretchable members 34 from the first position shown by the phantom lines in FIG. 4, to the second position shown by the solid lines. In this way, the muscles of the arms, shoulders, the back and the stomach can be progressively exercised.

[0027] Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention as set forth in the following claims.
