Description
FIELD OF THE DISCLOSED TECHNOLOGY
The disclosed technology relates generally to physical therapy, and more specifically, to decompression of the back.
BACKGROUND OF THE DISCLOSURE
Back pain is often the result of improper posture, such as slouching or even sitting too much. This can result in compression of the spine which causes pressure on nerves and discs. The pain impairs a person's ability to function and can get worse over time, leading not only to physical problems but also mental conditions. Treatments include physical therapy, exercise, physical therapy, steroid injections and even surgery.
Methods in the art to relieve spinal compression include stretching exercises, decompression tables, inversion tables, inversion chairs, and back stretching apparatuses. Such apparatuses include U.S. Patent Publication 2014/0142487 to Arico, disclosing a harness on a torso having straps with as many as 10 points of connection to vertical anchor points; U.S. Pat. No. 5,626,540 to Hall disclosing a support apparatus for a torso of a standing person; and U.S. Pat. No. 7,601,132 to Nichols et al. disclosing a traction assembly with a chair.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE DISCLOSED TECHNOLOGY
A spinal decompression harness which hangs from two lines on each side is attached to a stand. A stool or seat is between the two sides of the stand, and the stand can be attached to a neck of the stool. In this manner, the harness is movable between the two sides of the stand, and one can rotate one or more of the harness, seat, or stand, while keeping their torso abutted to the harness. Their arms can also extend over or through the harness and be used for writing, typing, and other work, while their spine is decompressed in the harness.
Embodiments of the disclosed technology will become clearer in view of the following description of the figures.
FIG. 1 shows a side elevation view of a back decompression unit attached to a stool, in an embodiment of the disclosed technology. Here, the back decompression unit has a harness 90 suspending by flexible lines 12 from a top region 10 of a stand. The flexible lines 12 having a fixed and equal length, such as rope, nylon string, or the like, allow the harness to hang, via gravity, from a portal or connection mechanism 18 within the top region 10 of the stand, such that a plane of the harness is disposed substantially parallel to the ground. The top region 10 of the stand can be raised and lowered from a bottom region 30 by way of a series of portals 16 and a peg passing into the portal or other mechanisms known in the art.
The stand has a lateral lower section 32 with a stool neck 48 attachment portal 34 (see FIG. 2). The stool neck attachment portal 34 attaches around a neck 48 of a stool or other chair. The neck 48 of a stool is the elongated region between the legs 42 and seat 46 of the stool 40. The seat of the stool 40 can be raised or lowered and can turn. The harness can also be raised or lowered by raising the top section 10 of the stand. In this manner, the orientation of the harness 90 and person sitting in the stool 40 can be rotated around a plane which is parallel to the ground in 360 degrees. For purposes of this disclosure, the ground is a support surface on which the stool 40 and/or stand 30 rests.
FIG. 2 shows a front elevation view of the back decompression unit attached to a stool of FIG. 1. Here one can see that there is a cuff 34 which forms the stool neck attachment portal. Thus, the stand (10/30/32), in this embodiment, is supported by the neck 48 of the stool 40 and is situated between the wheels and seat of the stool. The arms on the side have a lower portion 30 and upper portion 10 which rise above the height of the stool. As such, the line 12 allows the harness 90 to hang down from the stand and remain above the stool 40. In this manner, one can move/roll the stool 40, along with the stand to a desired location and remain in the harness. Thus, for example, one can place the entire apparatus in an office and use the device while typing at a computer by rolling the device in front of the computer and going about one's daily activities while in the harness 90. The harness 90 keeps the back stretched, in embodiments of the disclosed technology, by situating the harness 90 at a height above the stool, such that the vertebrae are stretched apart and the back is held straight.
The harness 90, in embodiments of the disclosed technology, has a straight mid-portion 94 with padding 92. Side-arms at number 90 in FIG. 2 wrap around the sides of a person's body, while the front of his/her body abuts elements 92 and/or 94 in use. A person's arms are free to be used on either side of the lines 12, between the lines 12 and the top portion 10 of the stand.
FIG. 3 show a top plan view of the back decompression unit attached to a stool of FIG. 1. Here, one can see the stool beneath, and sidearms extending above, and wider than the stool. As seen in FIGS. 2 and 3, when in a resting position without human intervention, the harness is disposed directly above and spaced apart from the seat of the stool 40, and is centered with respect to the seat of stool 40.
FIG. 4 shows a side elevation view of a back decompression unit with separate stool, in an embodiment of the disclosed technology. In this embodiment, the stand is free-standing on a base 38 which supports the lower portion 30 and upper portion 10. Otherwise, the device functions just like the device of FIGS. 1-3.
FIG. 5 shows a front elevation view of the back decompression unit with separate stool of FIG. 4. The stool 40 is freely movable above the base 38 of the stand. Handles 39 can be used to attach the stool further. The stool can be straddled over the base 40 and the base 40 can engage the bottom-most region of the stool. Note that there are many open areas which allow for free range of movement. For example, between upper sides 10 of the stand, each flexible line 12, and the harness 90 one can enclose a triangle 89 by extending an imaginary line from the harness laterally across to the stand. This area is free for placement of one's arms, allowing one to use arms and hands while in the harness. One can further rotate the harness 30, 45, 60, 90, or 180 degrees. Depending on the configuration (e.g., length and tautness of the lines) they can be maximum values of rotation. The stool, and specifically the top/seat 46 of the stool 40, can rotate in 360 degrees in embodiments. Further, the stand can rotate about the stool by way of its cuff 36, so one can actually turn one's body and/or one's stand around in a circle. Their back stays stretched in the harness, and they can move and work at the same time.
FIG. 6 shows a top plan view of the back decompression unit with separate stool of FIG. 1.
While the disclosed technology has been taught with specific reference to the above embodiments, a person having ordinary skill in the art will recognize that changes can be made in form and detail without departing from the spirit and the scope of the disclosed technology. The described embodiments are to be considered in all respects only as illustrative and not restrictive. All changes that come within the meaning and range of equivalency of the claims are to be embraced within their scope. Combinations of any of the methods, systems, and devices described hereinabove are also contemplated and within the scope of the disclosed technology.
