provide a brace arranged to be anchored to thev heel of a shoe and to engage a wearers leg for limiting 'movement of the Wearers foot.
Another object is to provide a brace which will substantially lock against movement in one direction about a pvot associated with they ankle of a wearer, and permit a limited resilient yielding movement in the opposite direction as an aid to persons ailiicted with drop-foot.
Another object is to provide a brace which may be readily transferred from one shoe to another, and locked in operative relation to a selected shoe.
Another object is to provide a'brace in which provision is made to prevent chaiiig of a wearers leg due to movement of t'he brace.
My invention possesses other objects land features of value, some of which with the foregoing will be set forth in the following description of the invention. It is to be understood that I do not limit myself to the showing made by the said description and the drawings as I may adopt variant forms of the invention within the scope of the appended claims.
In the drawings: Y
Figure l is a side elevation of applied to a shoe.
Figure 2 is a front elevation of t'he brace, detached from the shoe and sleeve. f
Figure 3 is an inner end elevation of the interengaging sleeve and pin portions of the brace mounting, drawn upon an enlarged scale.
Figure 4 isa fragmental side elevation, partly in section, of the inner end portions of the interlocking sleeve and pin, drawn upon an enlarged scale.
` In terms of broad inclusion, the drop-foot brace of my invention comprisesva heel piecedetachably anchored to the heel of a wearers shoe, and a pivoted extension extending upwardly from the heel piece along t-he back of the wearers leg and having means for securing the brace to the leg. The extension is resiliently yieldable in one direction about the pivot, and is locked against movement beyond a predetermined point in the the brace as lother direction.
In terms of greater detail, the drop-foot brace of my invention comprises a substantially L- shaped heel piece I having an upright back portion extending upwardly at the back of the heel and a bottom portion 2 arranged to underlie the heel of a wearer. The back portion of the heel piece I is preferably made of bar metal of a suit-2v able weight, strength andresiliency, such as steel or spring lbrass,l while the bottom or vheel engaging'portion 2 is preferably a pin or rod of circular cross-section riveted, Welded or other-r Wise secured to the back portion I. The bottom portion is preferably arranged to be detachably secured to the heel 4 of a shoe 3 by means of a" sleeve 5 inset in a recess 6 formed inthe heel t' and opening outwardly aty the back thereof. A lip IIiis turned inwardly at the inner end of' ther sleeve, to providey a key for effecting inter' locking engagement with an annular groove I'I formed in the pin adjacent its inrner end. A longitudinal groove I8 permits the lip to enter the groove I'I when the pin moved into the sleeve with the groove I8 in registry with theflip' I6, the lip being held in the groove for locking the pin in the sleeve when the pin is turned to move the groove I8 and lip I6 out of alignment. Preferably the lip I6 and groove I8 are positioned to permit the lip I 6 to enter the groove I8 when the brace is moved to a substantially horizontal posi tion. so that the pin and sleeve will be eifectually interlocked when the brace is moved toits n'ormal upright position. A sleeve 5 may be provided in each of any number of shoes so that the brace may be attached to whichevershoe the wearer may select.
n The pin 2 is freely rotatable within t'he sleeve 5, and permits the foot yto be turned from side to side through an adequate rang-e of vmovement about the ankle joint.
The upwardly extending back portion I of the heel piece is positioned immediately in back of the heelportion of the shoe and terminates at a point substantially opposite the ankle of a wearer. An extension 'I is pivoted to the upper end of the heel piece by meansv of a pivot joint 8 arranged toY permit a limited relative movement of thepar'ts'in lone direction, and to lock them against relative movement beyond a predetermined point in the opposite direction.
A leaf spring 9 is secured to one of the parts, preferably the extension 1, by a screw IU or other suitable securing means. Clips II yieldably bind the leaves of the spring 9 together and to the heel piece and extension. The spring 9 normally holds the extension 'I in substantial alignment with the upright back portion I of the heel piece, and in a position suc'h that a very small degree of pivotal movement will cause the heel piece to be locked against pivotal movement in a clockwise direction as viewed in Figure 1 of the drawings.
