The present application claims priority to U.S. Provisional Patent Application No. 61/580,369, filed Dec. 27, 2011, entitled “Portable Therapeutic Stretching, Strengthening, and Spinal Traction Device”. The entire disclosure of this application is incorporated by reference herein.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a portable therapeutic stretching, strengthening, and spinal fraction device.
2. Description of Related Art
Current vertical gravity traction devices used today for relief of back pain are typically large, heavy and expensive devices that require significant space for use, prohibit mobile use of the device, and are prohibitively priced for many consumers. Additionally, the existing full body vertical gravity traction devices do not integrate a mechanism for articulating anterior, posterior, and lateral movement of the spine in an anatomical upright position with kinetic anterior, posterior, and lateral motion. Furthermore, such devices prohibit a user from controlling the adequate upper to lower back body motions and pressure applied to enhance the relief of back pain.
In view of the shortcomings of the existing traction devices, it is desirable to overcome the above problems and others by providing a vertical gravity fraction device used for stretching, strengthening, and/or relief of back pain. Additionally, there is a need for a portable therapeutic stretching, strengthening, and spinal traction device that is lightweight, portable, is significantly less expensive than the existing devices, and offers the user the ability to laterally articulate and control the adequate upper to lower back body motions with anatomical positioning and kinetic motion and pressure applied to enhance the relief of the user's back pain. Additionally, it is desirable to provide exercise routines, by providing for stretching and strengthening functionality.
SUMMARY OF THE INVENTIONIn view of the foregoing, a need exists for an improved therapeutic stretching, strengthening, and spinal traction device and method for installing and using the therapeutic stretching, strengthening, and spinal traction device. An additional need exists for a therapeutic stretching, strengthening, and spinal traction device that is lightweight, portable, is significantly less expensive than the existing devices, and offers the user the ability to laterally articulate and control the adequate upper to lower back body motions with anatomical positioning and kinetic motion and pressure applied to enhance the relief of the user's back pain. Additionally, it is desirable to provide exercise routines, by providing for stretching and strengthening functionality. As described in detail herein, a portable therapeutic stretching, strengthening, and spinal traction device and method for installing and using the portable therapeutic stretching, strengthening, and spinal traction device are disclosed.

The exercise device 10 and the exercise device assembly 20 allow the user to perform a plurality of different stretching, strengthening, and spinal traction exercises. For example, the user may firmly grip the bar and suspend the torso in a vertical position, bending the knees at a 90° angle. The user can then begin to apply pressure from the feet to move the body forward and backward in a controlled rocking motion that will provide the user with anterior and posterior movement necessary to stretch his or her back. The user may also perform a lateral stretch. For example, to stretch the right side of the body, the user would apply pressure from their right foot and twist their body to the left, crossing their right knee toward the floor as they cross to the left side of their body. To stretch the left side of the body, the same steps would be employed, but in reverse. Various other exercises are possible to help the user achieve the desired degree of stretching, strengthening, and spinal traction.
Having described the exercise device assembly 10 and exercise device 20, a method of manufacturing the exercise device 10 will now be described. The method includes the step of providing a pair of clamping members 80 having an elongated body extending between the first end 90 and the second end 100 and the arcuate portion 110 extending from the second end 100 and terminating at the free articulating end 120. The method further includes the steps of pivotally connecting the pair of clamping members 80 to each other at the first pivot point 130 provided between the first end 90 and the second end 100 and attaching the pair of gripping members 140 on the free end 120 of the arcuate portion 110 of the pair of clamping members 80 such that the gripping members 140 face one another. Furthermore, the method also includes the step of pivotally connecting the pair of links 150 to the exercise device 20 where each link 150 is pivotally connected to one of the clamping members 80 at the second pivot point 160 provided between the first pivot point 130 and the first end 90 of the clamping members 80. Additionally, the method further includes the step of pivotally connecting the links 150 to each other at a third pivot point 180 and attaching an elastic member 170 between the second pivot point 160 of the pair of clamping members 80. The pair of clamping members 80 is movable between a first position where the gripping members 140 are urged toward one another and a second position where the gripping members 140 are separated from one another. The elastic member 170 is adapted for providing a restoring force to urge the pair of clamping members 80 to a first position. The method further includes the step of connecting a hook 30 to the pair of links 150 at the third pivot point 180. The method further includes the step of connecting a stretching or strengthening device 40 to the hook 30.
