1. Field of Invention
The present invention relates generally to a therapeutic support device and more particularly to a therapeutic foam support device that is made of a material that is firm and flexible, that has a shape and design that both conforms comfortably to various portions of the human body having a curvature, thus providing supportive properties, and compresses against the muscle portions of a human body, thus providing relaxant properties.
2. Description of Prior Art
A variety of supportive “pillow-type” products have been used for many years to provide either orthopedic support or provide muscle-relaxing effects. The orthopedic support generally was for the lumbar or cervical areas of the back and spine. This was accomplished in prior art by use of air or liquid filled pillows, or pillow-type products that were filled with a variety of form-conforming fillers, such as grains, beads, and the like, or solid structures that offered no form-conforming properties, such as plastic or wood supports that may be shaped like a specific area of the body to which it was intended to apply.
There were a number of variations over the years made of wood and other products that were too stiff for using on the floor and other purposes. The disadvantage of those products are that they were too hard and did not provide comfort when the product is placed behind one's back for traveling, or when lying on the floor as a muscle relaxant behind one's neck to relieve stress. The materials used in the prior art either provided “give” yet were not firm enough to perform as an adequate support or muscle relaxant, or were too firm and didn't provide “give” necessary to conform to the affected body part to perform as a muscle relaxant. The wood products, for example, offer no “give” which makes those devices difficult and uncomfortable to use.
The current invention is also easy to make and inexpensive to make.
The current invention provides for flexibility or “give” while maintaining firmness to provide both support and resilient muscle relaxant properties.
It is the principal object of this invention to provide an improved and superior orthopedic and muscle support therapeutic device. It is a further object of the current invention to provide stress relief.
It is a further object of this invention to provide an inexpensive yet effective therapeutic support and muscle relaxant.
There are many special types of pillows that have been developed but do not provide the same pneumatic air release to conform to one's body while providing a level of desired firmness.
Other objects and features of the current invention will become apparent from considerations of the following description taken in conjunction with the accompanying drawings.

In a second embodiment, the device can be manufactured in a one piece or two piece extrusion process, whereby the device would comprise a main cylinder 2 with a void within the interior of the main cylinder 2 acting as the free air chamber 5, said free air chamber 5 void located at the center of the main cylinder 2 and comprising one-third of the length of the main cylinder 2 and further comprising a diameter of one-half the diameter of the main cylinder 2, said main cylinder 2 further comprising two small diameter holes 6 at each end of the main cylinder 2 located at the center point of each such end, whereby when the main cylinder 2 is compressed, air would be able to flow out of the free air chamber 5 void through the two small holes 6, and when the main cylinder 2 is uncompressed, air would flow back into the free air chamber 5, again through the two small holes 6. The preferred embodiment would have the device 1 made out of foam or some other such flexible, compressible material.
The current invention works on a pneumatic basis whereby once a person's head, neck, back or any other body part is rested upon the device 1, the weight of the person will cause a small amount of air to discharge from the device 1 and at the same time, maintain a comfortable level of firmness, thus providing the desired outcomes for the therapeutic results from the product. Once the product is no longer in use, the air returns naturally to the center of the free air chamber 5 and the product is immediately ready for another purpose. Thus, the invention provides for support along its length while at the same time providing give at its center. The invention can be used for many purposes, such as providing stress and therapeutic relief on one's back by lying on the device on the floor, behind one's neck while viewing television, working in an office chair, an automobile, airplane and many other uses. It could further be used for kneeling upon, such as in performing gardening or construction work, and can be used for camping and many, many other recreational uses.
A preferred embodiment would have the user placing the device 1 against his or her back, aligning the center of the device 1 with the user's spine. The device 1 compresses, allowing air to escape the free air chamber 5 thus allowing the device 1 to conform to the user's back, putting pressure on the muscles of the back without adding pressure or strain to the user's spine.
