Oct. 6, 1953 A. L. WHITAKER COMBINED BODY AND LEG BRACE Filed Nov. 14, 1949 2 7/ 7 F lilL Zlrwwwfom iiaker Patented Oct. 6, 1953 COMBINED BODY AND LEG BRACE Archie L. Whitaker, Altadena, Calif.

Application November 14, 1949, Serial No. 127,214

(Granted under Title 35, U.- S. Code (1952),

see. 266) 10 Claims.

The invention described herein may be manufactured and used by or for the Government for governmental purposes, without payment to me of any royalty thereon.

The present invention relates to prosthetic devices, and more particularly to a combined body and leg brace which enables the wearer of an artificial leg to impart natural movements to the leg, or to a natural leg immobilized by any form of motor paralysis.

More particularly, the invention relates to a combined body and leg brace that is particularly adapted to senile scoliosis, the brace embodying an improved type of universal joint. which permits natural universal movement to either an aim ficial leg or to a natural leg which. is crippled by motor paralysis.

It will be apparent, therefore, that. any essential feature of the invention resides in the. fact that there is interposed behveen a pelvic brace and the bucket. portion of the leg, a universal joint which permits normal movements ofv the leg when the individual is walking or sitting for enabling the leg, to be. opened or moved in any direction.

A further object of the invention is the provie sion of an improved universally acting ball. joint intermediate the pelvic brace and the bucket-portion of the leg, the joint employing approximately three-fourths of a. sphere, the joint allowing un- O restricted motion of the. leg.

A. still further object of the. invention is the provision of an improved slip lock mechanism which enables the pelvic. brace and leg, brace: portions of the appliance to be. rigidly and strongly,

yet removably, interconnected.

Further objects of the invention will becomeapparent as the description proceeds, and. the, feature of novelty will be pointed out in particularity in the appended claims.

The invention will be understood more readily by considering the. accompanying drawings. wherein:

Fig. 1 represents afront. view of the. improvedprosthetic appliance of. the present invention;

Fig. 2 is a side View;

Fig. 3 is a fragmentary front view of. onezoi the. leg brace members showing the improved universal joint and slip lock means of. the. present invention;

Fig. 4 is a. fragmentary sectional elevation of the parts of Fig. 3 below the joint-showing details of the slip lock mechanism for joining the leg and. body braces of the-appliance;

Fig. 5 is a detailed enlarged sectional elevation: 55.

taken through the vertical axis of the joint; and

Fig. 6 is a lateral sectional elevation of the joint taken on the line VIVI of Fi 5.

Referring more particularly to the drawings, the improved prosthetic appliance of this invention comprises an upper, stiff, body-supporting brace or corset 8- made of heavy leather which encloses the lower half. of the body trunk and. is particularly adaptable for use in cases of senile scoliosis. The corset 8 is adjustable by straps Iii and buckles l2.

Laterally secured tothe corset brace 8 and forming a. part thereof is a metal carrier bar It, shaped to conform to the curvature of the body, and is threadedly secured in. an internally threaded: hinge member 1-5 and secured by lock nuts Iii.

The lower end. 20 of the: hinge member is flattenedand. has a hole therethrough for receiving an approximately spherical steel ball 2| that is diametrically oppositely flattened. somewhat to seat in the enlarged bifurcated end 22 of the lower leg brace: bar 24.

The ball 2| has a. holetherethrough for receiving a pin 25, which extends through registering holes the: sides 28- of the bifurcated end 22. of the: lower leg brace bar 24',- the end of the pin 25 being threaded. for receiving; a wing. nut as for holding. the pin 25 and theball-I 2! inposition. By making the ball: 22! with. oppositely flattened surfaces, the proper centering of the hole through the ball is facilitated and the thickness of. the joint is reduced. The resulting; universally acting trochantericv joint is: positioned when the: device is in service,-. slightly posterior and higher than the greater trochanter. as is: indicated? diagrammati-- cally in" Fig. 2'. The fact: that the hinge member i5 is turnablet on; thaball 2'! produces a universal movement between. the upper and lower brace bars.

It may be pointed. out at this point that themost common trochanteric' joint is. constructed. asa simple hinge or extension and flexionof. the hipjoint. This usual construction ofthe hinged double-action: joint permits motion in two planes or'fiexion and extension plus abduction and adduction with a feeling; of resistance on the part of the: wearer of such .zmpliance. The ball type of trochanteric joint of: the present invention gives movementv in two planes of. motion at the same time, namely fiexion and. extension plus abduction or adduction without restricted motion. Loss; of. balance has been noted especially with senile. scoliosis patients, anda. patient. wearing abody andleg brace without-freedom of movement 3 tends to be thrown in case of a fall. With the ball type of trochanteric joint of the present invention the feeling of resistance is not experienced if the upper or lower body needs quick movement if loss of balance occurs.

It is found in practice that it is desirable to make the leg portion of the brace detachable from the body portion. For this purpose an improved slip-joint has been provided.

For this purpose, a leg-brace bar 2!; engages a reinforcing bar 32, the upper end of the latter, which terminates adjacent to the enlarged end 22 of the bar 24, being provided with an end guide bracket 34 through which the bar 244 is slipped, and also being provided with a second guide bracket 35 under and through which the bar 2t extends.

A relatively thick but short locking bar 38 is secured to the brace bar 32 by means of a screw 46. This bar 33 together with the bar 32 forms a pair of complemental bars which retain the brace-bar 24 between them, as will be pointed out hereinafter, the bars 38 and 32 reinforcing the brace-bar 24 and making a rigid assembly for carrying the leg brace, the bars of the assembly mutually reinforcing each other. The bar 38 is provided with reinforcing guides 4|. One end of this locking bar 38 is undercut to receive the end of the brace-bar 2 the undercut end 42 of the locking bar 38 forming an abutment for the end of the brace-bar 25, the remainder of this bar extending from its undercut end portion defining a flange member which extends forwardly on the upper surface of the brace-bar. Overlying the resulting assembly is a spring strip t l riveted adjacent to one end by rivets 46 to the looking bar 38. The other end of the spring strip .4 has secured on its underside a stirrup-bracket 42, the sides 56 of which frictionally engage the sides of the assembled bars 24 and 32. This stirrup-bracket 48 is held in place by rivets 5i and carries a projecting lug 52 that locks into a hole 5% provided therefor in the brace-bar 24. The resulting assembly constitutes a rigid and strong joint.

In order to release the assembly and separate the leg brace frame from the corset 8, the upper end of the spring strip 44 is lifted manually to disengage the lug 52 from the hole 5 3, thus releasing the leg brace frame from the bracebar 24.

The leg brace frame is shown as comprising the upper or bucket support 56 which is of stiff leather and is secured in a well-known suitable manner to the complemental bar 32 and an opposite br 58 which terminates just short of the crotch of the wearer. The lower ends of the bars 32 and 58 terminate in knee joints 60, and are continued by the lateral bars 52 and {54 which extend along the leg to the ankle joint, not shown. A second leather support 65 which is connected to the lateral bars 62 and 64, supports the leg just below the knee joints.

It ma be noted that the oppositely flattened surfaces of the ball 2| facilitate the location of, and drilling through, the center of the ball. In practice, these flattened surfaces are such that the spherical portions of the ball amount to approximately three-fourths of a complete sphere, thus reducing the thickness and weight of the joint without impairment of the universal movement thereof.

It will be apparent from the foregoing that a structure has been provided by the present contribution which affords an effective brace,

which also permits quick movement without a feeling of resistance if the lower or upper portions of the body needs quick movement for recovery if loss of balance occurs. The construction also permits a convenient means for detaching the leg brace portion from the remainder of the brace; and while the preferred form of the invention is shown in the accompanying drawings and described above, it will be apparent that the invention contemplates modification in structural details which still permit the attainment of the advantages inherent in the present construction. It will be apparent, therefore, that it is intended and desired to embrace within the scope of this invention such modifications and changes as may be necessary to adapt it to varying conditions and uses, as defined in the appended claims.
