Application August 8, 1957, Serial No. 677,046

4 Clains. (Cl. 128-78) This invention relates generally to orthopedic braces, and has particular reference to an improved spinal brace adapted to effect a stretching or spreading action between spaced points on the spine of the wearer of the brace.

More specifically, the present invention is an improvement upon the spinal brace disclosed in U. S. Patent No. 2,160,709, issued May 30, 1939, to the applicant herein, and the fundamental purpose of the improved brace and the previously patented brace is the same. pointed out in the patent disclosure, the brace is adapted to exert pressure in opposte directions at two dierent locations on the spine to effect a stretching of the spine or a separation of the spinal segments, .this treatment being known in medical science as a hyper extension or hyper flexion of the spine; As a result of this stretching or spreading of the spinal segments, abnormal pressures between contiguous vertebrae can be releved' and misalgned vertebrae are enabled to work back into their normal positions.

In the spinal brace disclosed in the above noted patent, the brace consists of an arched or concavo-convex spring having pads secured to its ends on the concave side thereof and a belt attached intermediate the pads overlyng the conveX side. When the pads are placed against the spine and the belt is tightened around the body of the wearer, the spring arch is flattened which causes the pads to spread farther apart and exert pressure in opposte directions on the spine. Unfortunately, however, at the time that Patent No. 2,160,709 was applied for it was thought by medical scientists that quite a marked separation of the vertebrae was required in order to givethe desired relief and therefore a relatively heavy spring with quite a pronounced arch was employed in the brace. As a result' of this construction, the belt cannot be tightened enough to completely flatten the spring (and still permit the brace to be worn), and the spring makes a noticeable bulge beneath the Clothing so that many people will not use the brace in spite of the relief and beneficial treatment it aords.

Since the applicant's original spinal brace was patented in 1939, physicians, surgeons and neurologists have learned from many years of examination, X-ray studies and research that marked separation of the spinal segments or vertebrae is not possible, and is not necessary to produce the relief desired. Since it is now known that separation in terms of a hundredth of an inch or less can relieve abnormal pressures and enable realignment of misplaced vertebrae, the present invention contemplates and has as its primary object the provision of a greatly improved spinal belt wherein the spring member is constructed so as to efiect the separation required for relief but will not cause an unsightly bulge beneath the clothing of the wearer.

Another important object of the invention is to provide an improved spinal brace of the above described type which permits a high degree of mob'ility and body comfort to the patient being treated.

A further important object of the invention is to pro- Thus, as is Patented Feb. 3, 1959 vide an improved spinal brace of the above described type which is lightweight and compactly designed.

A still further important object of the invention is to provide an improved spinal brace of the above described type which is strong and durable and yet can be economically manufactured and sold,

A more specific object of the present invention is to provide a spinal brace of the above described type wherein the spring member for the brace is constructed in such a manner that the required spring action and resultant opposte pressures are obtained without the necessity of forming a pronounced arch in the spring, the spring being considerably fiatter than any heretofore developed for this purpose so that when the belt for the brace is'tightened around the body of the wearer there will be no unsightly bulge beneath the wearer's clothing. s

Other objects and advantages of the invention will become apparent from the following detailed description thereof read in conjunction with the accompanying drawings which illustrate a representative embodiment of the invention for the purpose of disclosure.

In the drawings:

Figure l is a side elevation of an improved spring'member Construction embodying the invention, the spring member being shown in normal or unstressed condition;

Figure 2 is a side elevation corresponding to Figura 1,

` showing the conformation of the spring after pressure has been applied thereto by means of the belt for the brace;

Figure 3 is a diminutive perspective View of a complete spinal brace embodying the invention, showing the interrelationship of the spring member and body encircling belt; and j Figure 4 is a fragmentary side elevation of a portion of the spring member andthe upper body engaging pad, showing the adjustable means for attaching the latter to the former. 4

Having reference now to the drawings, wherein like reference numbers designate the same parts in each of the views, 10 generally indicates the spinal brace which comprses a spring member 11, a pair of pads 12, 13 secured to the ends of the spring member, and a fabric belt 15 overlying the outer side of the spring member and adapted to encircle the body of the patient or wearer. The spring member is preferably provided with a fabric covering (not shown) which is secured by any suitable method to the fabric of the belt. The beltitself is provided with a plurality of front straps 17 which are adjustably engageable with hook connections 18 to 'secure the belt in position on the body of the wearer, the belt also being provided with a back lacing 20 to further enable the brace to be comfortably adjusted to and tightened on the body of the wearer to apply the required force on the spring member 11.

The pads 12, 13 are preferably in the form of metal plates which are cushioned with sponge rubber or the like on the side of the wearer and and covered with fabric. The upper pad 12 is adjustably secured to spring member 11 as by a screw and slot connection 21, and the lower pad 13 is fixed to the member as by a pair of screws or rivets 22.

The spring member 11 is preferably in the form of. an

elongated metal strip having a length equal to four or In accordance with the present nvention, the sinusoidal conformation of the spring as above described eliminates the large spring arch previously thought necessary and consequently reduces the widthwise displacement of the spring. By tightening the belt 15 about the body of; the wearer, a force F is applied to the spring: as indicated by the arrow 23 in Figure 2, and this force acts to flatten the centrally disposed arch or sine loop 26 which in turn causes the pads 12, 13 to be spread further apart. The pads in this manner exert opposite pressures upon the spine and eventhough the increased separation of the pads as effected by the application of the force to the arch or loop 26 is relatively small, the pressures applied are relatively strong and efiect as much of a separation of the vertebrae as is now known to be possible.

In actual practice, the lower pad 13 is in most cases positioned against the sacrum, or base of the spine, while the upper pad engages the spine at the four or fifth vertebrae. The lower pad in eifect thus becomes a fixed point with the upper pad being raised slightly to effect a lifting action when the belt is tightened. i This aids in the correction of abnormal pressures between the vertebrae due to faulty weight hearing thereon as above mentioned.

In addition to reducing the size of the spring arch 26 in the present invention, the widthwise displacement of thus allows relief without embarrassment and, as a result,

many people who would not wear this type of a brace before will now take advantage of beneficial treatment atforded thereby.

The invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiment disclosed is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims.
