0 1 0 BOM 8H38 DU B 6 .vA J 3 8 8 2 [50] Field of PATENIEU JANZB 197i INVENTOR JAMES WAFER ATTORNEY BRAC E APPARATUS This invention has particular reference to unique leg appliances or bracelike substitutes of distinct therapeutic, as well as orthopedic, value to those afflicted persons who have difficulty in standing and walking.

Victims of diseases such as cerebral palsy or poliomyelitis are often times incapable of either standing or walking without support of their arms. This is due to the lack of coordination and muscular control. Moreover, even when their muscular control and coordination starts to improve, their mental attitudes make it very difficult to get them to try to stand alone, let alone to try to walk. This last can be easily understood when one considers the fact that devices heretofore available for the assistance of such afflicted persons have involved arm supports in the nature of parallel bars and crutches. The use of such supports does not readily give the handicapped the courage to stand or walk without them except after long and difficult periods of physical training.

The present invention provides simple but unique embodiments the use of which quickly overcomes many of the physical and mental problems of afflicted persons such as above described. In their preferred form the embodiments consist of bracelike leg attachments which afford stabilizing influences enabling the wearer to stand and make an effort to walk without the need of arm supports.

It should be pointed out that when a person finds standing or walking either very difficult or almost impossible, he becomes mentally depressed. This retards efforts to rebuild his body. Thus, by making it possible for a person with deficient or defective underpinning to stand without arm supports and even to take a step or two without falling on his face, the present invention provides an inherent therapeutic benefit.

A primary object of the invention is to provide a bracelike attachment for application to the legs of a person afflicted with difficulty in standing or walking which is economical to fabricate, most efficient and satisfactory in use and adaptable to suit a variety of needs.

A further object of the invention is to provide means to encourage standing and walking by persons whose physical conditions make the same extremely difficult.

Another object of the invention is to provide apparatus enabling persons afflicted with vertical instability or poor muscular coordination to stand and make effort to walk with greater confidence.

An additional object of the invention is to provide apparatus possessing the advantageous structural features, the inherent meritorious characteristics and the means and mode of use herein described.

With the above and other incidental objects in view as will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combination thereof, and the mode of operation as hereinafter described or illustrated in the accompanying drawings, or their equivalents.

Referring to the drawings wherein one but not necessarily the only form of embodiment of the invention is illustrated,

FIG. 1 illustrates an application of a preferred embodiment of the invention to the legs of a person afflicted with cerebral P y;

FIG. 2 is a view taken from the side of the person shown in FIG. 1;

FIG. 3 is a front view of the invention apparatus as applied to the leg;

FIG. 4 is an exploded view of the invention apparatus and the means of attachment thereof; and

FIG. 5 is a detail view of a fragmentary portion of the invention apparatus.

Like parts are indicated by similar characters of reference throughout the several views.

Referring to the drawings, it may be there seen that the invention device in the preferred form illustrated consists of an open framework 10. This includes an A-shaped portion 11 adapted to orient vertically of a ground surface with its apex uppermost. The portion 11 includes downwardly divergent sidebars 12 bridged at their centers by a cross bar 13 and adjacent and spaced from their lower ends by a further crossbar 14. It is to be noted that the crossbar 13 is fixed at what might be considered the inner surfaces of the bars 12 while the bar 14 is fixed to their opposite or outer surfaces. Note further that the upper end of the one bar 12 is offset to overlie the upper end of the other bar 12 in forming the apex of the A- frame. The bars 12 are connected at this apex by a pin 15.

Connected to the base of the A-frame 11 is a semicircular frame portion 16. The respective extremities ofthe semicircu lar frame portion 16 are mutually bent on the diameter thereof to provide short links which are fixedly pinned to the respective lower extremities of the bars 12 of the A-frame 11. Further included in the framework 10 is a brace bar 18 one extremity 19 of which is fixed at the center of the semicircular frame portion 16. From its extremity 19 the bar 18 extends upwardly. first with a gentle inclination in the direction of the frame portion 11 and then. more sharply towards a horizontal to extend inwardly of the frame portion 11 over the approximate center of the bar 13. The extremity of the bar 18 remote from its extremity 19 is bent directly upward to accommodate the projection therethrough of the pin 15 and be fixed in abutting relation to the apex of the frame portion 11. Also fixed to a further projected portion of the pin 15 is a plate type bracket 20 including a horizontally oriented projected loop 21.

Referring to the drawings, it is there seen that for purposes of illustrating the invention in application to the legs of a person afflicted with cerebral palsy there is shown attached to the legs of the individual conventional strengthening brace bars 22 which are conventionally applied to the legs and to the shoes. The details of such structure will not be further described except as modified to accommodate the application of the open framework 10. As seen in FIG. 4 of the drawings, fixed in vertically spaced relation on the outer surface of the outermost of the brace bars 22 are a pair of

brackets

23 and 24. The bracket 24 is uppermost and includes a vertically elongated base which is attached by screws to the adjacent bar 22 and a projected loop portion 25 defining an aperture corresponding in diameter to that in the loop 21. On the other hand. the bracket 23 which is adjacent the lower end of the same bar 22 includes a vertically elongate base attached to the bar 22 and horizontally projected arms the projected extremities of which are formed with vertically ofien ted loops 26. 4

Take particular note of tlie rad that the bar 13 of the frame portion 11 has welded thereto a pair of horizontally spaced vertically dependent pins 27. The spacing of the pins 27 correspond to the spacing between the loops 26 on the bracket 23.

Thus, it may be readily seen that where a conventional strengthening leg brace is applied to the handicapped person, the device of the invention may be simply and readily attached. The

brackets

23 and 24 may be suitably secured to the outer face of the outer bar of each leg brace unit of the wearer and the open framework 10 readily applied by disposing the pins 27 in the loops 26 of the bracket 23 and simultaneously the loop 21 is aligned with the loop 25 on the bracket 24. A threaded bolt 28 is then inserted through the aligned

loops

25 and 21 to have its projected extremity receive thereon a washer 29 and a nut 30. Once the nut is applied and tightened the structure 10 is in position in respect to each of the legs.

Attention is directed to FIGS. 2 and 3 of the drawings which clearly indicate that the suspension and connection of the framework 10 is such to dispose the A-frame portion 11 vertically and slightly outward of the side of the leg, the base of the A-frame and the interconnected diametrically aligned portions 17 of the frame portion 16 seating to the ground. At the same time, it will be seen that the orientation of the frame portion 16 at this point, in the preferred embodiment illustrated, is at a small angle to the ground surface.

Accordingly, when the handicapped person wearing the bracelike supports 10 to either side of his legs assumes a standing position there will be a base support adjacent and spaced outwardly of each side of the person. This support is elongated in reference to the foot of the wearer so that it projects forwardly and rearwardly of the foot, and to a greater distance to the rear. The structure as described has a tendency to prevent a fall either forwardly or backwardly. At the same time, the braced base portion 16 gives a slight rocking freedom of the individual from side to side which is natural for unstable persons of the type with whom we are here concerned. In the event of any lateral rocking, the projected frame portion 16 quickly gives the person an extended and broad base inhibiting an actual falling to the side. Therefore, the effect of the attachment of the bracelike structure is to give a broad and extremely stable base to the wearer. This lends considerable confidence to the person who finds that in spite of his physical handicaps he will not fall. Another advantage of the angularity of the frame portion 16 to the base of the frame portion 11 is that it facilitates the wearer of the brace structures stepping forward and in the course of stepping forward inhibits the tendency to stumble or fall, the frame portion 16 accommodating a rocking to the side and the extension of the base of the A-frame inhibiting the tendency to fall forward on the face.

It will thus be seen that the invention provides an extremely simple and economical structure which takes into consideration the problems at hand. The use thereof results in the wearer being immediately imbued with a degree of self-confidence which is mentally stimulating, particularly in that the wearer finds that with the apparatus attached there is a minimal need for arm supports to assist in standing or walking. Tests have shown that children afflicted as described who have been incapable of self-help previously have with the benefit of the invention devices enjoyed a new ability for selfhelp in standing and walking.

From the above description it will be apparent that there is thus provided a device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less specific as to structural features, it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise but one of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the appended claims.
