Abstract:
The adjustable exercise therapy device of this invention has first and second handles suitable for manual grasp and a single bungee cord passing through both handles. The bungee cord is adjustably attached to one of the handles. Between the handles, a tube holds the two stands of the bungee cord together. The distance between the handles can be adjusted so that the device is suitable for use as an exercise device for people of limited strength.

Description:
FIELD OF THE INVENTION 
     This invention is directed to an adjustable exercise therapy device which has first and second handgrips connected by a resilient bungee cord. There is adjustability for length between the handgrips to adjust for the user&#39;s size and the stiffness of the pull between the handgrips so as to be particularly useful for disabled persons who get little arm and/or leg exercise. 
     BACKGROUND OF THE INVENTION 
     There are many persons of limited physical capability who have the need for physical exercise. In some cases, doctors prescribe exercise. In other cases, persons realize they need some exercise and try to do what they can. However, the exercise devices used by persons of full physical capability are usually too strong for those of limited strength. Furthermore, adjustability is required so that the person of limited strength can operate with the exercise therapy device in the optimum position so that no excess stress and strain are created. Thus, there is need for an adjustable exercise therapy device suitable for persons of limited physical capability. 
     SUMMARY OF THE INVENTION 
     In order to aid in the understanding of this invention, it can be stated in essentially summary form that it is directed to an adjustable exercise therapy device which comprises a bungee cord with a pair of handles attached thereto. At least one of the handles is adjustable along the length of the bungee cord so that the length between the handles can be chosen in accordance with the type of exercise and the size and condition of the person desiring the exercise. In one type of exercise, the cords are passed through a flexible tube which is positioned against the back of the user. 
     It is, thus, a purpose and advantage of this invention to provide an adjustable exercise therapy device which has a pair of handles and which is provided with adjustment so that the distance between the handles can be adjusted so that it is useful for different exercises and different persons utilizing the therapy device. 
     It is another purpose and advantage of this invention to provide an economical adjustable exercise therapy device which is convenient and comfortable to use and which can be adjusted so that it is suitable for different exercises and different persons so that it is widely available to those in need of such an exercise therapy device.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The adjustable exercise therapy device of this invention is generally indicated at  10  in FIGS. 1 and 2. The device  10  has first and second handles  12  and  14 . The handles have cylindrical or close to cylindrical exterior surfaces. They may be tubular or may be solid, as shown. The diameter is such as to be comfortable when fully grasped in the hand by the person  16  who is exercising, as shown in FIG. 1. A diameter of 1 inch to 1½ inches is suitable. The material of the handles is substantially rigid and may be metal, but a synthetic polymer composition material such as acrylic is preferred, both because of appearance and because it does not feel so cold in the hands. The length of each handle is such as to extend out of the hand of the exerciser a sufficient distance so that the ends are free, as shown in FIG.  1 . 
     As seen in FIG. 2, the first handle  12  has first and second holes  18  and  20  therethrough adjacent its ends. One-piece bungee cord  22  has a loop  24  on the front of the handle  12 , while its stands  26  and  28  extend through the holes  18  and  20  in the handle  12 . The stands  26  and  28  of the bungee cord  22  pass through back tube  30 . Back tube  30  is flexible polymer composition material and is considerably larger than the two stands of the bungee cord, as seen in FIG.  5 . The purpose of this size is to permit the back tube to spread the load of the force on the person&#39;s back when the exerciser uses the device  10 , as shown in FIG.  1 . Thus, the tube  30  is flexible, but not limp. It would be undesirable for the back tube  30  to have creases or folds therein which would localize force on the back of the exerciser  16 . 
     The second handle  14  has first and second holes  32  and  34  therethrough, which holes are substantially larger than the standard bungee cord  22 , as seen in FIGS. 3 and 4. The stands  26  and  28 , respectively, pass through these holes  32  and  34 . The second handle  14  has threaded holes in the top and bottom, respectively, into the holes  32  and  34 . The threaded hole  36  is shown in FIG.  3 . Clamp screw  38  has a rounded nose and is threaded to engage in the hole  36 . Clamp screw  38  carries knob  40  thereon. The knob  40  is at least as large as the diameter of handle  14  for ease of grasp and tightening. As seen in FIGS. 3 and 4, the stand  26  engages through hole  32 , and the rounded nose of the clamp screw clamps onto the bungee cord to secure it in place by pressing it against the interior wall of the handle hole  32 . A similar clamp screw and knob  42  are provided adjacent the second hole  34 . 
     The exerciser adjusts the length between the handles  12  and  14  when the bungee cord is not stretched. Adjustment is accomplished by laying out the device  10 , loosening the clamp screws  38  and  42 , and moving the free ends through the handle  14  to the desired position. Thereupon, the clamp screws are tightened. 
     When adjusted, the adjustable exercise therapy device  10  can be used. One of the exercises is as shown in FIG. 1 where the back tube rests against the exerciser&#39;s back below her shoulders. The elbows are bent when the bungee cord is slack. Exercise is accomplished by thrusting both handles forward at the same time. This exercises her shoulder and arm muscles. The heel of the hand presses against the handles, and there is no wrist action, so as to avoid carpal tunnel stress. If greater force is desired, the effective length of the bungee cord can be shortened. In this exercise, the arms are not swung wide and brought forward but, in all cases, the elbows are held close to the body. 
     In another exercise, the foot can be placed in one of the handles, and the other handle held in one or both hands. The leg can be exercised by bending at the hip and knee while the resistance and consequent muscular exercise is provided by the one or two hands holding the upright of the device  10 . In that way, one leg can be exercised at a time, while one or both arms are exercised by providing the resistance at the upper end of the device. 
     Other exercises are also possible with the device  10 . The holes  18  and  20  in handle  12  and holes  32  and  34  in handle  14  are much larger than the size of the standard bungee cord. Similarly, the back tube  30  has an interior diameter much larger than is required for the two stands of the bungee cord. This is because the device is configured so that, when the exerciser feels the need for more strenuous exercise, a heavier than standard bungee cord can be installed therein. This provides further variation in the capability of the device  10 . 
     This invention has been described in its presently contemplated best embodiment, and it is clear that it is susceptible to numerous modifications, modes and embodiments within the ability of those skilled in the art and without the exercise of the inventive faculty. Accordingly, the scope of this invention is defined by the scope of the following claims.
