DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The present invention relates to a device that can be worn under clothing to decompress the lower spine relieving pain and promoting healing of lower back problems such as Spinal Stenosis, Degenerative Disc Disease, Herniated Discs, Muscle Spasms, and Sciatica. The device includes an upper strap or belt worn below the breast line and a lower strap or belt worn in the normal belt position riding on the hip. At least two rigid splints extend vertically between the two belts on the left and right sides of the body. When the wearer stands or sits, the lower spine is gently decompressed.

[0021] Turning to FIG. 1, an embodiment of the present invention is shown being worn. Each of the straps or belts is approximately five inches wide with sets of pockets on opposing edges. A splint can be seen extending vertically between the straps on each side of the body. The splints can be captured and held in place by the pockets. The pockets are optional; the splints can be permanently attached to the straps in some embodiments. Also, a plug or other device can be inserted into the holes at each end of the splint through the pocket and strap. The splint holes can be larger or smaller than the pictured in FIG. 7. FIG. 1 shows the device being worn outside the clothing for clarity. While this is possible, normally the device is worn under clothing so as to not be as visible.

[0022] FIG. 2 shows the device assembled, but not being worn, while FIG. 3 shows it exploded. The upper and lower straps 1, 2 are approximately five inches wide. Each strap can be approximately forty-five inches long with an overlapped region that uses hook-loop fasteners known in the trade as VELCRO. Any other method may be used to secure the straps. The straps can thus be fitted to most wearers. Longer and shorter straps can be supplied for very large and very small wearers. While, the dimensions given are preferred, the straps can be made in any convenient sizes. The preferred material for the straps is neoprene; however, any flexible material may be used, including, but not limited to leather or other polymers.

[0023] FIGS. 2 and 3 also show a pair of splints 3 on the left and right sides of the device that are received and held by pockets 4, 5. The splints can be made from any rigid material with molded rigid plastic being preferred. Other materials can be metal or wood. Any material that is rigid as a flat splint can be used. The lower end of the splints can optionally be split or U-shaped to cup over a standard belt in the case the wearer prefers to wear only an upper strap. The splints are typically between eight to thirteen inches long with preferred sizes being approximately 9.00 inches, 10.75 inches and 12.00 inches. Any length of splint may be used. The splint extends from an upper strap under the shoulders to a lower strap on the belt line. The width of the splint can be between 1 inch and 3 inches with approximately 2 inches being preferred. The width of the splint is not critical as long as the splint fits snugly against the side of the body. The thickness of the splints can be between 0.15 inches to 0.25 inches with a preferred thickness being approximately 0.1875 inches. The thickness is not critical as long as the longest splint is thick enough to not bend outward in compression (column instability), but rather remain rigid.

[0024] It should be noted in FIGS. 1-3 that the splints 3 are located directly on the sides of the user's body. The are centered laterally. Centered laterally means that they are centered on right and left sides of the torso under the armpits. The optional additional pockets are only used so that different sized users can locate a splint directly on each side of their body, i.e. center it laterally. The device will not provide the required decompression if the splints are not on the sides of the body.

[0025] The pockets 4, 5 typically have slots that receive the splints. The pockets on the upper strap are typically on its upper edge, while the pockets on the lower strap are typically on its lower edge. The two straps can be identical with the lower strap simply flipped over when worn so that its pockets are on its lower edge. The slots should match the width and thickness of the splints so that they are held firmly in place by the straps 1, 2. As stated, the pockets are optional; the splints can be permanently attached to the straps by any known method.

[0026] FIGS. 4 and 5 show an embodiment of the strap 1 with three pockets 4 on the left and right sides. The center pocket is used for most users. Again, the extra, optional pockets are only used to assure that the splints are aligned with the left and right side of the user's body for different sized users. While three pockets are shown on each side, any number of pockets including only one pocket (or no pockets) on each side is within the scope of the present invention. The pockets 4 are securely attached to the strap 1. As stated, the preferred material for the strap 1 is neoprene, and the preferred material for the splint 3 is hard plastic.

[0027] FIG. 6 shows the straps and splints of FIGS. 4-5 assembled. It should be noted that the top pockets 4 face downward, and the bottom pockets 5 face upward to receive and hold the splints. This alignment of the pockets occurs using identical straps for top and bottom by simply flipping the strap over depending upon whether it is used in the top or bottom position.

[0028] FIG. 7 shows top and side views of splints 3 of three preferred lengths 9.00 inches, 10.75 inches and 12.00 inches. Splints of these lengths can be supplied as stock items. Special splints of other sizes can also be made. Splints of any size are within the scope of the present invention. While other preferred dimensions are also shown in FIG. 7, all of the dimensions in FIG. 7 are for example only. The splints can be made with any other dimensions.

[0029] The splints 3 in FIG. 7 are shown with a flat end 20 and a forked or U-shaped end 21. The flat end 20 fits into the upper strap pocket 4, while the forked end 21 is the bottom end that either is received by the lower pocket 5 or forks around a standard belt worn around the hips. Splints can also be made with both ends flat or both ends forked.

[0030] The splints 3 of FIG. 7 are shown with small holes 23, 24 in their ends. These holes are optional, can be made any size, and can be used with removable plugs that secure the splints 3 to the pockets 4, 5. These, when used, allow the user to remove the belt and splints as a one-piece harness for convenience. However, plugs are typically not required to be used as the invention relies on the compressive forces between the straps 1, 2 to hold the splints 3 in the pockets 4, 5.

[0031] FIG. 8 shows a front and back view of a strap. FIG. 8 also shows example dimensions. Again, all of the dimensions in FIG. 8 are for example only. The straps can be made with any dimensions. The upper part of FIG. 8 shows the front of a representative strap; the lower part of FIG. 8 shows the back. Both the front and the back have a surface of loop material 31, 32. Hook material appears in strips 30a and 30b at the ends of the strap. There is hook material on both sides of the strap at different ends. This allows the strap to attach to the user's body at two different locations preventing slippage. While this is a particular embodiment of hook/loop material, any other arrangement of hook/loop material or any other method of holding the strap securely in place is within the scope of the present invention.

[0032] FIG. 9 shows an embodiment of the present invention being worn with only one strap using a standard belt for the lower strap. This embodiment may be preferred by users who do not wish to have to wear two straps. Again, the device is shown worn outside the user's clothing. Typically however, the device will be worn under clothing to make is less visible.

[0033] The present invention relates to a device that decompresses the lower spine of a wearer while standing or seated relieving pain from lower back problems and providing a better environment for long-term healing. In addition to Spinal Stenosis, the present invention is useful for general Spondylosis conditions such as, degenerative disc disease, herniated disks, sciatica, muscle spasms and other causes of lower back pain.

[0034] Several descriptions and illustrations have been presented to aid in understanding the present invention. One with skill in the art will realize that numerous changes and variations may be made without departing from the spirit of the invention. Each of these changes and variations is within the scope of the present invention.
