Filed May 14, 1958, Ser. No. 735,331

10 Claims. (Cl. 12S-80) This invention relates to orthopedic braces, one object being to provide an improved brace mechanism for supporting and steadying the feet in suitably adjusted positions, while enabling the wearer to move and exercise them more freely and naturally in stance and gait. More specifically stated, it is an object of the invention to provide such a mechanism by which the feet of the wearer may be effectively braced in such a way as to allow freedom of movement approximating normal functioning in stance and gait, including relative movements between the feet either forwardly'and rearwardly, or up and down, or both, to enable the wearer to walk on a level surface or up and down steps.

A further object is to provide a mechanism having the above advantages in a construction which is practical and light in Weight and adapted to be readily and economically manufactured and applied to the shoes of the wearer.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

- In the drawings:

Fig. l is a top plan view of a brace mechanism embodying the above invention partly broken away and before application to the shoes;

Fig. 2 is an elevation of the same with parts in section and showing attachment to the shoes;

Fig. v3 is a fragmentary plan view of a modified construction of the parallelogram linkage;

. Fig. 4 is an elevation substantially on the line 4-4 in` Fig. 3, and

Fig. 5 is a fragmentary plan View of a further modification of the parallelogram linkage.

-The preferredembodiment of the invention, herein disclosed by way of illustration, comprises a pair of members for attachment, respectively, to the shoes of the wearer, the members carrying parts which are connected by a parallelogram linkage to afford movement of each shoe, relative to the other, in forward and rearward directions, as in walking, While the members attached to the shoes are connected to the ends of the linkage by joints affording pivotal movements about axes extending forwardly and rearwardly so as to permit the wearer to s tep upwardly and downwardly as well as to walk forwardly in approximately normal stance and gait. VVReferring more particularly to the drawings, the construction comprises a pair of plate-like members for attachment, respectively, to the soles 11 of the shoes 12 ofthe wearer, as byY means of rivets or other suitable attaching means (not shown).` Each member 10 preff. ICC

erably extends from the heel to the ball portion of the foot and is of substantial width so as to afford stable support for the shoe and foot.

Each member l0 has secured to its bottom, under the instep region of the shoe, a cylindrical boss 13, as by means of rivets 14 secured through the flanged base of the boss and member 10. The periphery of boss .13 is serrated, notched, or toothed in any suitable manner, as indicated at 15, for engagement in an opening withA a similarly formed periphery in a plate-like part 16. A screw 17 is passed through member 10 and boss 13 and carries at its lower end a nut 18 for securing the part 16 on boss 13. It is apparent from this construction that part 16 may be removed from its boss and replaced and secured in a different angular relation with the longitudinalaxis of the shoe, to adjust each shoe independently to a desired angular position with relation to a direction extending forwardly and rearwardly of the wearer. A wear plate 19 is preferably secured in spaced relation to the underside of member 10, as by posts 20, for stable contact with the ground, to facilitate walking and to protect the elements of the brace, and the under surfaces of plates 19 are preferably surfaced with leather, rubber or other suitable material 21 to cushion the contact with the ground and prevent slipping. f The parts 16 of the shoe supporting members 10 are pivotally connected to the ends of the parallelogram linkage indicated generally at 22. For this purpose, the inner ends of parts 16 are secured as by rivets 23 to the half portions 24 of hinge type joints, the other half portions of which 25 serve as the end links of the linkage. The shoe supporting members 10 are thus pivotally jointed with the ends of the linkage for movement about horizontal axes 26 to enable the wearer to raise and lower one foot relative to the other as in stepping up and down stairs.

The linkage comprises connecting links 27 and 28 pivotally connected at their ends with the hinge parts 25 for movement parallel with each other in the advancing movement of one foot relative to the other. Each connecting link is preferably made in two parts having overlapping ends, as indicated generally at 29, such ends being formed With longitudinal series of holes 30 for the reception of screws 31 threaded into one of the links, and it is apparent from this construction that each link may be adjustably varied in length. Such adjustment of the length of one link relative to the length of the other provides a second way of altering the position of the members 10 and shoes in their angular relation to the forward and rear direction and while such adjustment tends to alter the parallel relation of the connecting links, it may be employed in a limited way, temporarily or intermittently, to thus vary the angular relation of the feet, as particular cases may require. Such alteration of both links may also be employed to vary the distance between the shoes. Such angular relation may be accomplished by the adjustment between parts 16 and members 10, as described above, or by such Yalteration of the lengths of the connecting links 27 and 28, or both, as circumstances may indicate.

It is apparent from the above description of the construction that it enables the wearer to move each foot forwardly and rearwardly as in walking, as well as up and down as in mounting stairs, in ways closely approximating normal stance and gait, with the beneficial exercise which has been found to aid in the restoration of normal functions, as in the treatment of derangements of the lower limbs or feet and serves as well inl restoring to the wearer the conveniences and comforts of natural locomotion.

A modified construction is shown in Figs. 3 and 4, in

which the parts 16 of the above construction are replaced by plate-like members 32 each having a pair of lugs 33 fixed thereto as by means of rivets 34. Lugs 33 have their inner faces recessed to provide sockets for the reception therebetween of balls 44 carried on stems 35 clamped between lugs 36 fixed to the ends of the connecting links of the parallelogram as by means of rivets 37, thus providing joints of the universal type between the ends of the links and the parts 16 of members 10. v A further modification is shown in Fig. 3 by which means are provided for clamping the connecting links of the parallelogram against relative movement, where found to be temporarily desirable, or for intermittent use as particular cases may require. Such means comprises a pair of plates 38 removably clamped to the sides of the connecting links of the parallelogram as by means of a small bolt 39. A lug 40 is secured between the plates 38 and between the adjacent edges of the connecting links so as to clamp the same securely together and prevent relative movement therebetween, as may be found desirable, for example, at particular times for progressive treatment in particular cases.

In cases where it is found desirable to assist the wearer in bringing the feet back to positions of uniform advancement with each other, resort may be made to the modification shown in Fig. 5, in which a leaf spring 41, of the bowed shape shown, is secured between the connecting links of the parallelogram as by attachment of one of its ends to one of the links by a suitable clamping clip 42, so that with the spring under some initial tension, it tends to press the links apart and thus restore the parallelogram to a rectangular shape, with the feet of the wearer in uniformly advanced or neutral positions.

The invention thus provides an orthopedic brace mechanism which effectively positions, steadies and supports the feet while permitting the motions of both walking and stepping up and down, as in substantially normal stance and gait and as found highly effective in restoring the normal functions and convenience and comfort of the wearer in the prevention or correction of abnormal positioning or functioning of the lower limbs or feet.

It will thus be seen that the inventionv accomplishes its objects and while it has been herein disclosed by reference to the details of preferred embodiments, it is to be understood that such disclosure is intended in an illustrative, rather than a limiting sense, as it is contemplated that various modifications will readily occur to those skilled in the art, within the spirit of the invention and the scope of the appended claims.
