FIELD OF THE INVENTION
The present invention relates to a stretching device, and more particularly to a stretching device for training and therapy.
BACKGROUND OF THE INVENTION
A conventional stretching device is disclosed in U.S. Pat. Nos. 5,456,649, 4,419,990, 864,188, yet it cannot cure muscle tension. Another conventional stretching device is disclosed in U.S. Pat. Nos. 7,841,973, 6,705,974, 4,819,936 so as to stretch muscle groups, such as hamstrings, calves and Achilles tendons, but it cannot stretch muscles of an upper body.
In addition, U.S. Pat. No. 6,569,069 discloses a ‘Back Stretcher’ device which is used to stretch the spine but it is only applied to stretch abdominal muscles, so the back muscles cannot be stretched effectively.
Also, a traction exercise apparatus is disclosed in U.S. patent filing Ser. No. 12/729,016 and US Publication No. 2011/0230808, yet the user's legs have to be tied and the body is hanged upside down, having an unsafe and impractical operation. Furthermore, the user must use much force to grip the handle bars thus not allowing his shoulders to relax, the position of the users head tilting backward is contrary to the position needed to fully stretch the back and neck, the position of the user's feet are not flexed to stretch the calves and hamstrings, thus the therapeutic stretching is insufficient and incomplete.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a stretching device for therapy which in operation, the base is placed on the ground, and the inclined foot platform is sloped 30 to 40 degrees relative to the ground, then the frame abuts against the upright member, and frame is adjusted to match various users' body sizes and flexibility levels, thereafter a user stands on the inclined foot platform, stoops down and places his/her hands through and grips the two handle loops while keeping legs straight and leaning backward to stretch his/her body, hence the user is capable of stretching calves, hamstring, lower back, upper back, shoulder and neck, also to provide traction to the spine.
To obtain the above objectives, a stretching device for therapy provided by the present invention contains:
a base including a inclined foot platform axially connected therewith and tilting backward, the inclined foot platform having an upright member extending upwardly and connecting with a front end thereof, and the upright member having two handle loops mounted thereon relative to a user's waist;
wherein the base further includes a first frame, a second frame, and a third frame, the first frame has an outer rack, two adjustable supports, and the inclined foot platform, the inclined foot platform is axially connected with the first frame, and the two adjustable supports are positioned between the inclined foot platform and the outer rack, and the second frame is axially connected with the front end of the first frame, the third frame is coupled with the second frame.
