Description:

This invention relates to foot corrective devices, and more particularly to devices designed to alleviate or rectify deformities of the toes, such as bunions, corns, calluses, hammertoes, and the like.

Devices of this nature commonly have the disadvantage of producing such unnecessary discomfort as to limit their use to the degree of tolerance of the particular individual; :.. One object of my invention, therefore, is to : provide a device of the character described in which the corrective, locating and retaining portions are so constructed and arranged that a minimum of discomfort will be produced in use, and that the surrounding parts of the foot will be shielded and protected.

Another object of my invention is to provide a device of the character described which shall afford relief from localized pressure and surface friction in the region of the affected parts of the foot and thus prevent the occurrence of secondary focuses of irritation not brought about by the affected area itself.

A further object of my invention is to provide a foot corrective device which is uniquely designed to remedy a digital deformity without the application of more than the necessary corrective pressure.

An additional object of my invention is to provide a device of the character described which shall comprise relatively few and simple parts; which shall be inexpensive to manufacture and easy to use; and which shall withal be highly effective for the purposes set forth.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the construction hereinafter described, 4 and of which the scope of application will be indicated in the claims.

In the accompanying drawing, in which are shown two of the various possible embodiments of this invention, and wherein like numbers refer to like parts, Fig. 1 is a plan view in section of a foot corrective device embodying my invention in position on a big toe; Fig. 2 is a side perspective view of said device; Fig. 3 is a plan view thereof immediately prior to the final assembly step; Figs. 4 and 5 are sectional views taken along the lines 4-4 and 5-5 of Fig. 3; and Fig. 6 is a side sectional view of a smaller corrective device in position on a small toe.

Referring now to the illustrations, and more particularly to Figs. 1 through 5, 10:is a foot cor:rective device comprising outer and inner strips II and 12 of substantially equal length, which are made from a soft, pliable material such as kidskin. The grain side of the strips II and 12 are faced outwardly and the flesh or rough sides contacted and adhesively joined, as with rubber cement, to form a strap portion 13 having a smooth exterior. The strips may be so arranged that one end 14 of each strip projects a short distance beyond the corresponding end of the other strip, as shown in Fig. 3, and the projecting end portions 14 are adhesively connected in an overlying lap joint to provide a sheath 15 for the toe. It should be noted that said sheath is made long enough to entirely cover the toe in 20;order to relieve the same from any chafing action or pressure which: might otherwise arise due to the altered position which the toe is forcibly caused to assume when a defect such as a hammer toe, overlapping toe, or bunion is cor25B rected-.: ..: A portion of the contacting surfaces of the strips II and 12 may be left free of adhesive to form a pocket 16 and an entrance slit 17 provided adjacent an edge thereof to permit insertion of a sponge rubber pad 18 having feathered edges.

The pocket 16 may be positioned so as to aid in remedying any of various defects and in Figs. 1, 2, 3, and 5 it is so disposed that the pad 18 will lie between the big toe and the second toe to thereby aid in straightening the big toe and relieving the bunion.

Depending from the strips II and 12 are a pair of adhesively joined ears 19 and 20 of similar shape which support between them an apertured 10 oval pad 21 of resilient, flexible material, such as sponge rubber. The pad is closely contacted by the material comprising the ears 19 and 20 so that the contour of the pad is outlined on the exterior of the device and the central portions of 15 the ears contact each other through the aperture 23 in the pad. Said pad is specially shaped in accordance with my invention to uniformly apply sufficient pressure to correct a pedal deformity without causing the presence of spots where additional pressure is created, which pressure does not have any corrective action but which will cause irritation and soreness. Thus the forward portion 21 of the pad has a crosssection which is thinner and shorter than that of the rear portion 22, as is clearly illustrated in Figs. 1 and 4, and all edges of the pad are feathered.

It should be noted that the pad is adapted to be disposed over a callus with the aperture 23 centrally located on the callus, the forward portion 21 approximately centrally located on the phalange disposed forwardly of the enlarged joint, and the rear pad portion 22 approximately centrally located on the phalange disposed rearwardly of said joint. It will thus be seen that due to the configuration of the foot and shoes an approximately even pressure will be exerted on each of the said phalanges which will straighten the same and thus tend to reduce the inflamed bursa around the joint. At the same time pressure on the bunion will be relieved by the pad and chafing on the top of the bunion will be prevented by the presence of two plies of leather over the aperture 23.

As the entire portion of the foot up to the tip of the toe is covered by soft leather, and as no more than the needful pressure is ever applied, it will be apparent that my novel foot corrective device may be worn in substantial comfort and with the assurance that in correcting a painful pedal defect no sores will be caused.

In Fig. 6 I have shown my device applied to the correction of a hammer head on a small toe, it being noted that In principle the device is the same as that above described for the remedying of a bunion and differs therefrom only in size.

In application, however, the position of the sheath and ears are reversed, the ears and pad overlying the front and second phalanges and the sheath encircling the rear digital phalange.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent: 1. A foot corrective device for remedying enlargement of the head of the metatarsal bone of the great toe, comprising a pair of plies of porous material, each of said plies including a toe-encircling sheath portion adapted to extend over the tip of said big toe and an integral imperforate ear portion of sufficient length to extend substantially behind the head of said metatarsal bone, a sponge rubber pad apertured to receive the enlarged head at the side of the foot so that portions of said pad lie in front of and portions behind said enlarged head, said pad being disposed between said ear ply portions, said ear ply portions covering said aperture on both sides of said pad, and a second pad of sponge rubber disposed between the sheath portions in such position that it will be located between the great toe and the second toe, said second pad and the forward portions of said first pad tapering in thickness forwardly and rearwardly along the axis of said tubular sheath from a point of maximum thickness, the point of maximum thickness of said second pad adapted to lie adjacent the foremost phalange of said great toe, and the point of maximum thickness of said forward portion of said first pad adapted to lie adjacent the rear phalange of said great toe.

2. A foot corrective device for remedying enlargement of:the head of the metatarsal bone of the great toe; comprising a pair of plies of porous 30, material, .each of said plies including a toe-encircling sheath portion adapted to extend over the tip of said big toe and an integral imperforate ear portion of sufficient length to extend substantially behind the head of said metatarsal bone, a sponge rubber pad apertured to receive the enlarged head at the side of the foot so that portions of said pad lie in front of and portions behind said enlarged head, said pad being disposed between said ear ply portions, said ear :ply portions covering said aperture on both sides of said pad, and a pocket between said sheath ply portions for receiving a second pad adapted to be disposed between the big toe and the second toe.
