Fl E LEATHER \zusggg 34 53 2a INVENTOR. Ph/ll J Kr/b fan BY Q C M A TORNEYS SHOE INSOLE Philip Kristan, Sandusky, Ohio Application February 6, 1958, SerialNo. 713,618 1 Claim. (Cl. 3671) ticularly, to an orthopedic insole.
So long as shoes have been worn, such foot disorders as calluses and bunions have been a plague to humanity. Although numerous efforts have been made to develop shoes which would not cause disorders of this sort, and shoes which would remedy the disorders, once they had been encountered, there is still a substantial need for an effective remedy. The present invention is based upon the discovery of an improved insole for shoes, which insole is especially fabricated to eliminate calluses, bunions, or the like on the foot of a particular wearer,-or to prevent the formation thereof.
It is, therefore, an object of the invention to provide an improved insole for mens, womens' and childrens 511068.?" Y l Other objects and advantages .will be apparent from the description which follows, reference-being made to the accompanying drawings, in which Fig. 1 is a plan view of the upper s de of a part of an insole according to the invention;
Fig. 2 is a plan view of the under side of the insole part of Fig. 1;
Fig. 3 is a plan view showing, a second insole part which is used in cooperation with the insole part-shown in Figs. 1 and 2 to produce the new insole; and
- propriately contoured layer of cork or other resilient This invention relates to a shoe insole, and, more par- Fig. 4 is a view in section showing an assembly produced from the insole part of Figs. 1 and 2 and, the second insole part of Fig. 3. Referring now in more detail to the drawings, and, in particular, to Figs. 1 and 2, an insole part producing an insole according to the invention is indicated generally at 17. I The insole part 17 comprises a base 18 of a suitable sheet material, such as leather, which base has a recessed under side. The recess is surrounded by a raised band composed of the sheet material of the base 18, which raised band is designated 20 and (as can be seen in Fig. 3) is of substantially uniform width and extends completely around the under side of the base 18. *A cork half liner i9 partially fills the recess which is surrounded by the band 20, being positioned in the forward part thereof, and an arch support 30 is positioned in the rear part of the recess.
A fabric or lining 2'1 is cemented or otherwise attached to the under side of the insole base 18, as shown in Fig. 4.-
Inorder to finish an insole according to the invention, a sock lining indicated generally at 32 in Fig. 3 is provided in alignment with the insole part 17, and immediately thereabove. The sock lining 32 is provided with two voids in which resilient pad members 33 and 34, which conform in shape, and are aligned, with the resilient pads 28 and 29, respectively, are positioned. As can be seen in Fig. 4, the sock lining-32 is composed-of a cork sheet 36 in which the voids that are filled with the resilient pads 33 and 34 are provided, and a flexible leather sheet 37 overlying the cork 36 and the pads 33 and 34. The lining 32 is cemented or otherwise suitably attached to the upper surface of the insole part 17, to 1 provide the insole structure shown in Fig. 4. v
The resilient pads 28, 29, 33 and 34 in the shoe 11 constitute an essential part of the instant invention.
These pads, as shown in the drawings, are shaped and positioned to correspond with and to receive and'spread the load imposed by the heei bone and by the third metatarsal of a wearer. Such arrangement is advantageous for a healthy foot, as it relieves much of the stress that is normally incident to standing and walking. In other instances the resilient pads 28, 29, 33 and 34 are positioned to correspond with calluses, bunions or the like on the ball or heel of the foot of a wearer. In either case, the portion of the flexible leather sheet 37 which overlies these pads is depressed,,either by one of the indicated bones or by the thickened skin of the foot in the area of the callus, bunion, or the like, and compresses the underlying pads. As a consequence, the pressure against the affected portion of the wearers foot is negligible, and the major part of the load involved in walking is spread over the remaining portions thereof. The shape and position-for a resilient pad or pads required by a particular wearer to correspond with calluses or the like can be determined by making a print of his foot. The
I print can be produced by applying a light coating of an ink to a pad or cloth, placing the pad or cloth on a piece Two voids are provided in the base 18, and resilient pads 28 and 29 are provided, substantially filling the respective voids. The walls of the base 18 surrounding the voids should be generally at right angles to the major surfaces thereof. The pads 28 and 29 can be of sponge rubber, foam rubber, or other resilient material, and can beglued or otherwise attached to the fabric or lining 27 which extends beneath the voids through the base 18. It is advantageous to'provide two layers of the resilient material to make up each of the pads 18 and 29.
As can be seen in Fig. 2, a bowed and resilient metal of paper, with a cover of cloth or the like over the inked pad or cloth, and having the person place one foot upon the cover and support his weight on that foot to produce a print on the paper. Any calluses, bunions, or the like in the ball or heel of the foot will. show asdarker areas in the resulting print, relative to the remainder thereof; resilient pads should be provided, as described, to correspond in size, shape and position with such darkened areas.
. It will be apparent that various changes and modifications can be made from the Isp'ecific details disclosed herein and shown in the attached drawings without departing from the spirit'and scope of the attached claim.
What Iclaim is:
I An insole assembly comprising a leather layer having a groove in its underside extending generally parallel to the side face of the layer completely around the'underside of said leather layer, a. fabric base adhered to the underside of said leather layer, a resilient pad'in sheet form supported within, and substantially filling, a void provided through the thickness of the layer, said pad being radially surrounded by. portions of said layer,'-a
bowed metal arch support, means fastening-said arch iz eseram eaa in theme 5f this 5am "UNITED STATES PATENTS Goodyear Mar. 16, 1937 La Chapelle Apr. 6, 1948 La Chapelle' Sept. 26, 1950
