Cl. 128-583 Claims ABSTRACT OF THE DISCLOSURE An orthopedic shoe having a sole-like member providing a plurality of deformable calks or studs outwardly obliquely extended therefrom for deformation upon the application of the weight of the wearer to impart a force to the member which is opposite to the direction of the oblique extension of the studs. The studs are varied in form to impart turning and/ or tilting for correcting different types of defects.

Cross-reference to related applications This is a continuation-in-part of my copending application Ser. No. 450,803, entitled Orthopedic Shoe, filed Apr. 26, 1965, now abondoned.

Background of the invention The present invention relates to an orthopedic shoe for correcting defects in the skeletal and muscular system of the feet and legs of a wearer and more particularly to such a shoe which produces a beneficial orthopedic effect while permitting full mobility of the wearer.

The correction of deformities in the skeletal and muscular systems of the legs and feet of humans, particularly small children, has long been a problem. Persons afflicted with these defects are commonly described as pigeon-toed, spray-teed, club-footed, and the like. In many instances, corrective surgery is required and prior to the present invention was resorted to perhaps more frequently than needed because of the lack of suitable alternatives for even simple .afilictions. Such surgery has been expensive and in some instances hazardous. It has required complete immobilization of the patient and extended convalescent periods.

Braces have also been utilized quite extensively and, in many instances, to good advantage. However, such braces impair mobility, do not permit the wearer sufficient freedom of movement easily to accomplish other physical functions of the body and are cumbersome and difficult for the wearer to assemble and remove without assistance. During use, the braces are unsightly, require frequent adjustment, are uncomfortable, and are generally unsatisfactory. Furthermore, braces restrict the wearers activity, frequently impose undue strain on adjacent healthy portions of the body and reduce the amount of exercise which the patient is able to perform during the period of correction. The present invention recognizes that such corrective procedures can be greatly improved and accelerated by providing an orthopedic device which can be utilized in a manner which does not interfere with the normal activity of the wearer. Many of the foregoing remarks apply as well to the skeletal and muscular system of the feet and legs of animals, particularly horses.

Therefore, it is an object of the present invention to provide an improved orthopedic shoe for the correction of deformities in the skeleton or muscular systems of the wearer.

Another object is to provide such an orthopedic shoe which is readily embodied in forms individually directed to the correction of specific deformities of a wide variety.

hce

Another object is to provide an orthopedic shoe which may be used by wearers of all ages.

Another object is to provide an orthopedic shoe which is effective appreciably to reduce the required period of correction over that required by conventional devices.

Another object is to provide an orthopedic shoe which is capable of effecting such improved correction while permitting substantially full mobility of the wearer.

Another object is to provide an orthopedic shoe of the character described which is inexpensive, convenient to install and remove, comfortable to use, and which does not place undue strain on the wearer.

Other objects and advantages of the present invention will subsequently become more clearly apparent upon reference to the following description and accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First form Referring more particularly to the drawings, an orthopedic shoe embodying the principles of the present invention is shown in FIGS. 1 through 4 providing an upper foot receiving member 10 having opposite toe receiving and heel receiving ends 11 and 12, respectively. Connected to member 10 in underlying relation is a sole 15 which is constructed of a lightweight leather or pliable rubber, plastic or other suitable material. As best shown in FIG. 1, the sole has a continuous marginal edge contoured to follow the general shape of the bottom of a wearers foot and includes opposite inner and outer side edge portions 17 and 18, respectively. A heel 19 is rigidly secured to the sole 15 in underlying relation to the heel receiving end 12 of the upper foot receiving member 10.

Congruently secured to the front portion of the sole 15 in underlying relation is an oversole 20 of resiliently flexible material, such as composition rubber or the like. The oversole is provided with a plurality of elongated, flexible, integral, substantially parallel, protuberances or studs 22 extending obliquely downwardly therefrom toward the inner side edge portion 17 of the sole. The studs are conveniently frusto-conical, tapering to respective outer ends 23.

A heel plate 25 of the same material as the oversole 20 is congruently secured to the heel 19, the heel plate being similarly provided with a plurality of integral studs 26 which are substantialy identical to the studs 22 on the oversole 20 and have outer ends 27. However, as best shown in FIGS. 1, 3 and 4, the studs 26 extend obliquely downwardly from the heel plate toward the outer side edge 18 of the sole in a direction opposite to the oblique extension of the studs 22 from the oversole. Alternatively, the studs 22 and 26 may be constructed of a rigid material and be pivotally mounted on the oversole and heel plate in the obliquely extended positions shown in the drawings.

A somewhat modified structure of the first form of the present invention is shown in FIG. which, in addition to the structure previously described, includes a casing or cover of suitable resiliently flexible material generally indicated by the reference numeral 30 and disposed about the studs 22 and 26. The cover may be of unitary construction so as to extend the full length of the sole 15 or may be divided in opposite heel and toe portions individually to enclose the studs 22 and 26. The section of the shoe shown in FIG. 5 is taken through the heel portion of the shoe wherein it is seen that the cover 30 has side walls 32 which are connected to, or may be integral with, the heel plate 25. A lower wall or second sole 33 is disposed in interconnecting relation with the side walls in underlying relation to the outer ends of the studs 26 and 27. The second sole is conveniently integral with the outer ends of the studs.

With the addition of the cover 30 of FIG. 5, the lower wall 33 provides a wear surface which, during ground contact, precludes abrading of the outer ends 23 and 27 of the studs. Furthermore, when walking on soft or muddy ground, it effectively precludes the entrance of mud, debris and other foreign material between the studs. Accordingly, the cover enables the shoe of the present invention to be effective even when the wearer is walking on ground which ordinarily would not be sufiiciently firm to permit proper collapsing of the studs.

Operation of the first form The operation of the described embodiment of the orthopedic shoe of the present invention is believed to be clearly apparent and is briefly summarized at this point. With the orthopedic shoe of the first form disposed on the foot of a wearer, the weight imposed by the wearer on the sole 15 while standing, walking or running subjects the studs 22 and 26 to compression. The flexibility of the studs permits them partially to collapse or to deform under such compression. Since the studs are obliquely disposed, their partial or collapse deformation during flexing is akin to a pivoting action about their lower ends which imparts a component of force on the sole in a transverse direction opposite to the lateral direction of downward stud extension. During such deformation or collapsing of the studs 22, the sole 15 adjacent to the toe receiving end 11 of the shoe is shifted laterally to the right of the wearer or to the left as viewed from the front in FIG. 4. Where viewed from the rear as in FIG. 3, during deformation or collapsing of the studs 26 on heel plate 25, the heel receiving end 12 of the shoe is urged to the left. This causes the foot and leg of the wearer to be twisted or turned in a counterclockwise direction, as viewed in FIG. 1, during each step that is taken. Thus, to correct a pigeon-toed condition, the right foot of a wearer is provided with a shoe equipped with studs having the oblique extensions shown in FIG. 1. The left foot is provided with a shoe having studs which are oppositely laterally obliquely extended. .As a result, the studs impart opposite twisting forces to the shoes tending to spread the toes and to move the heels toward each other, as shown i FIG, 6. For

people having a tendency excessively to spread their toes, shoes are employed which counteract this tendency by opposite twisting forces, as illustrated in FIG. 7. For this purpose, the studs on the sole of the right shoe and on the heel of the left shoe are extended downwardly and obliquely to the right while the studs on the sole of the left shoe and on the heel of the right shoe are extended downwardly and obliquely to the left. Accordingly, during each step, the weight of the person is imposed on the studs and their partial deformation or collapse is utilized to impart the desired twisting forces to the feet and legs of the wearer.

It will be appreciated that the form of the shoe of the present invention shown in FIGS. 1 through 5 may be varied to accommodate the various types of previously discussed deformities by merely changing the direction of oblique extension of the studs relative to the sole of the shoe. In addition, the studs at one side of the shoe may be made longer than at the opposite side to obtain any desired transverse tilting. Similarly the studs at the heel may be made longer or shorter than those at the toe to achieve desired fore 0r aft tilting. Still further, opposite tilting of the heel and toe portions of a shoe can be achieved by making the studs at one side of the sole and at the opposite side of the heel longer than their respectively transversely adjacent studs and by utilizing a flexible sole. Thus, it has been discovered that by predetermining the relative stud lengths and the direction of oblique downward extension of the studs, a wide range of corrective forces can be caused to be imposed upon the feet and legs of a wearer of the shoes of the present invention while the user is standing, walking or running. Such universal accommodation to the orthopedic needs of a patient and the beneficial translation of forces inherent to standing, walking or running into corrective forces while permitting substantially full mobility has proved highly effective in treating structural and muscular difiiculties of the feet and legs.

Second form A second form of orthopedic shoe embodying the principles of the present invention is shown in FIGS. 8 through 13 and is generally designated by the reference numeral 40. The shoe is applied to the foot 42 of an animal, for example, a horses hoof, and is held in place by a plurality of nails 44. With particular reference to FIGS. 9 through 11, it will be noted that shoe 40 has an annular base or sole 46 of suitable resiliently flexible material similar to the material of the sole 20 of the first form which is reinforced or stiffened by an annular, relatively thin, somewhat flexible metallic plate 48 imbedded therein. The sole 46 and plate 48 are suitably perforated to provide a plurality of nail holes 50. Integral with or suitably secured to the sole is a plurality of projecting studs or calks 52 of frusto-conical configuration which extend obliquely downwardly therefrom and have groundcontacting ends 54. It will be appreciated that the sole 46 and the studs 52 are the counterparts of the sole 20 and the studs 22 of the first form and serve the same purpose. However, as shown in FIG. 9, the studs 52 are substantially circularly arranged in substantially equally spaced relation about the sole rather than in rows as in the first form.

In the case of defects which require more than mere turning or twisting of the foot for correction, the orthopedic shoe shown in FIGS. 9 through 11 may be varied in form to achieve transverse or fore and aft tilting or a combination of turning and tilting. Thus, some of the studs may be lengthened or shortened, or diametrically enlarged and strengthened to deform less, or vice versa, as necessary to obtain the results desired. FIGS. 12 and 13 show an example of one of such variations in which an orthopedic shoe 40 has elements similar to that provided by the shoe 40 including an annular sole 46' from which a plurality of calks or stud of various forms are obliquely extended. A pair of sets of opposed studs 52' are identical to the studs 52 of the shoe 40. However, a pair of studs 52" on one portion of the sole are thicker transversely than the studs 52, and are thus better able to support the weight of the wearer. A pair of studs are disposed on the sole in diametrically opposed relation to the studs 52" and are somewhat longer. With such a shoe there is some turning similar to shoe 40 but also, since the studs 52" are compressed a lesser amount than the studs 52' by the imposition of the weight of the wearer they therefore deform or collapse less, and cause some transverse tilting upward on the right side of the shoe. This is somewhat illustrated in FIG. 13 although, of course, in actual practice all the studs would be deformed or collapsed to some degree. The added length of studs 52" serves to initiate turning of the foot slightly ahead of the same action by the rest of the studs. And, of course, the studs could be utilized to impart tilting without turning.

Alternatively, the studs could all be of the same length but possess different degrees of flexibility to obtain the desired effects. However, making all the studs of one material and varying their forms for different effects is preferred because of greater ease and economy in manufacture of the shoes.

Shoe 40 and its variations may be modified after the fashion of FIG. 5 to encase the studs in a protective cover while permitting the desired action they provide.

Also in cases where only one of a pair of feet is defective, it may be desirable to fashion a built-up shoe with no corrective action for the non-defective foot merely to provide balance with an orthopedic shoe of the present invention on another foot.

Operation of the second form The operation of the second form of the orthopedic shoe of the present invention shown in FIGS. 9 through 13 is believed to be apparent from the foregoing description. However, briefly and in summary, with the oblique disposition of the studs 52, the imposition of the weight of the wearer on the sole 46 causes the studs to collapse which imparts a twisting or turning force in a counterclockwise direction or to the wearers right as viewed in FIG. 9. Thus, placed on the right foot, shoe 40 tends to turn the foot outwardly; on the left foot the urging would be inwardly. To obtain an opposite effect, the studs may be oppositely directed in their obliqueness from the sole. In the case of shoe 40, studs 52 being less compressive, the shoe is both turned to the wearers right and the right side of the shoe is tilted upwardly.

In view of the foregoing, it is readily apparent that the structures of the present invention have provided improved orthopedic shoes which are effective to provide a beneficial orthopedic effect during normal activity of the wearer without unduly restricting the mobility of the wearer. The shoe may be comfortably worn and is readily adapted to wearers of all ages for correcting varied types of deformities. The orthopedic shoes of the present invention are relatively inexpensive and can be worn without adversely affecting adjacent healthy body portions of the wearer.

Although the invention has been herein shown and described in what are conceived to be the most practical and preferred embodiments, it is recognized that departures may be made therefrom Within the scope of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and apparatus.
