The straps I2, anchor member I to vary the distance of the hinge rough adjustment of the angular position of the upper arm support or cradle 20 with respect to the anchor member I. The distance between the openings 42, 43, and 44 is preferably so related to the design of the turnbuckle 34 that adjustment of the turnbuckle accomplishes adjustment of the angular position of the upper arm support or cradle 2D, with respect to the anchor member to any position between the extremes provided by movement of the plate 39 and wing bolt 4|. A forearm support strip 45 is adjustably secured at one end to the extension strip `3| rby Ia bolt 46 which extends through van opening 41 in the forearm support strip 45 and through a longitudinal slot 48 in the extension strip 3| to provide a fulcrum for the forearm support strip 45; the forearm support strip 45 also being adjustable longitudinally of the extension strip3| by movement of the bolt 46 in the slot 43. `A wing nut 49 on thebolt 45 serves to secure the position yof the forearm support strip 45 with respect to the extension strip3 A brace 5B is fulcrumed to the extension strip 3| and upper arm support or cradle 25 by the l rivet 32 and has a longitudinal slot .5| therein. A wing bolt 52 extends through the slot 5| and is Vthreaded into the forearm support strip 45. The brace 55, being angularly disposed with respect to the extension strip 3| and'forearm support strip 45 and being fulcrumed to theextension strip 3l and adjustably secured to the forearmY support stripA 45 by the wing bolt 52, provides an additional means for positively determining the position of the forearm support strip 45 with respect to the extension strip 3l.
The forearm support strip 45 has a forearm cradle 53 adjustably secured thereto by a pair of bolts 54 and 55 that extend through a longitudinal slot 56 in the forearm Support strip 45 and have co-operating wing nuts 5] and 58, respectively. The forearm cradle 53 is `preferably prol vided with Ventilating openings, such as 59, and has an integral hand rest E9. The forearm cradle 53 is preferably uted at 5| between the hand` rest and the forearm support strip 45 to increase the rigidity thereof.
A substantially L-shaped hitch support 52is secured to the extension strip 3| by a pair of wing bolts and 34 and extends longitudinally outward from the ends of the extension strip 3l. The L-shaped hitch support 62` has openings 65 andgt in an angularly extending portion 67 thereof. An eyebolt 58 extends `through the opening and is provided with a co-operating wing nut 59 and a washer 75. l
The eyebolt 5B supports a hitchmember 'H and preferably has a compression spring 'l2 surrounding a portion thereof between the an'gularly 'extending portion |37- of the L-shaped hitch support and the washer 1l). is adapted to `hold the end of a strap 13 in tension for applying tractive force to the upper arm when such tractive force is necessary ordesirable.
In the use of the device disclosed ,and described herein, after the anchor member is firmly secuured in position with respect to the body of the patient, the angular relation` between the upper arm and body is adjusted and determined by determining the position of the plate 39 with I respect to the reinforcing strip ZBandby adjustment of the turnbuckle 34. When the wing bolt 52 and the wing nut 45 are loosened, the `florearm support strip is moved longitudinally of the extension strip 3| to effect adjustment corresponding to the lengthof the upper arm. At the The hitch member 'il' same time the angular relation of the forearm with respect to the upper arm is determined by the angular adjustment of the forearm support strip 45. After such adjustment, the wing bolt 52 and wing nut 49 are tightened to secure firmly the forearm support strip in place. The forearm cradle 53 is adjusted longitudinally of the forearm support strip 45 to correspond to the length of the forearm and properly place the hand rest 6G. 'Ihe entire device being practically symmetrica] except for the direction at which the forearm support 45 extends from the extension strip 3|, mounting is accomplished on either side of the patient by merely reversing the direction of the forearm support strip 45.
While I have illustrated and described a preferred embodiment of my invention, many modications may be made without departing from the spirit of the invention and I do not wishto be limited to the precise details set forth but desire toavail myself of all changes within the scope of the appended claims.
