United States Patent Oliliee 2,852,865 Patented Sept. 23, 1958 CONSTRUCTION OF LADIES SHOES John W. Spalding, Akron, Ohio, assigner to Remington Products Co., Akron, Ohio, a corporation of Ohio Application December 4, 1957, Serial No. 700,616
2 Claims. (Cl. 36-37) This invention relates to the construction of a ladys shoe, and particularly the lining of a high-style shoe. The invention includes both the shoe and the lining.
By a high-style shoe we refer to a shoe with a heel higher than a flat heel. In such a shoe the heel is suticiently high to cause the wearers foot to slide into the toe unless special means is provided to prevent this.
The heel of a high-style shoe is ordinarily attached to the sole of the shoe by nails and a screw driven down The heads of the screw and nails are exposed on the interior of the shoe. It is customary to cover these with a sock lining. The sock lining cushions some of the grosser irregularities in the inner surface of the sole, but is not particularly resilient.
According to this invention the heel portion of the sole, whether or not nails or screws or both have been used to attach the heel is covered with a thin sponge, and preferably a rubber sponge which cushions the heel and prevents irregularities in the inner surface of the sole from having any effect on the heel of a person wearing the shoe. 'This sponge is covered with a sock lining. The combination of the sock lining and sponge is referred to herein as a shoe lining.
There are openings in the heel of the sock lining used in the combination lining of the invention, and projections on the top surface of the cushion extend up through these at least substantially to the level of the top of the sock llining to provide an anti-slip surface on the inner foot-engaging surface of the shoe. The surfaces of these projections which are exposed through the openings in the sock lining present a sponge surface for contactwith the heel of the lady wearing the shoe (or of the ladys sock or stocking). This contact with the exposed sponge surfaces prevents the ladys heel, and thus her whole foot, from sliding forward toward the toe of the shoe. Such sliding is particularly objectionable in open-toed and pointed-toe shoes which are now in vogue.
The openings in the sock lining through which the projections on the sponge protrude are relatively narrow in at least one dimension. If they were not narrow in one dimension, the sock lining would lose shape. The preferred method of fastening the sock lining to the cushion is by cementing, and a lining which is capable of losing its shape is more apt to separate from the cushion, when in use, than a lining which cannot lose its shape.
The shape of the openings may be varied. They may be long, narrow openings running the length of the shoe, or they may be located across the shoe. They may be small, circular openings distributed over the entire heel surface. In fact, they may be any shape so long as the sock lining retains its shape. The openings may be in the form of a trademark, or the initials or name of the manufacturer, and in such case the openings may be made in the same manner as stencils with bridges across the openings at intervals so that the shape of the sock lining is maintained. The openings will be such as to make the shoe attractive and the sponge and sock lining may be colored diiferently to produce an attractive color contrast and saleability to the shoe.
The interior of the shoe of this invention is attractive, the sponge prevents the foot from slipping forward in the shoe, and the cushion is located under the wearers heel and cushions any irregularities in the surface of the sole construction at the heel, and the constant jar incident to walking.
The invention will be further described in connection with the accompanying drawings, in which- Fig. 1 is a top View of a shoe lining which includes a sock lining with a cushion under the heel thereof;
Fig. 2 is a vertical longitudinal section through a shoe, partly in section, constructed according to the invention; and
Fig. 3 is an exploded View ofthe heel portion of the sock lining and cushion, with the latter partly in section.
The cushion 1 is preferably a sponge-rubber .cushion but it may be a sponge of other composition, and -a lowdensity rubber which is not a sponge may be used. The cushion may be molded to the proper shape, or projections 3 may be cemented on to a .flat piece of cushioning material, or the projections may be formed in any desired manner.
As clearly shown in Fig. 3, the shape and arrangement of the openings 5 in the sock lining 6 are complementary to the shape and arrangement of the projections 3, so that when the sock lining is placed in the desired position on the cushion, the projections 3 extend upwardly into and possibly through the openings 5.
These openings 5 are relatively long in the direction across the shoe, but in the other direction are relatively narrow. The bridges 7 of the sock lining between the openings 5 prevent the sock lining from losing its shape. As the projections extend up through the sock lining their tops are substantially flush with the top surface of the sock lining or may extend somewhat above it. Unless they come at least substantially to the upper surface of thesock lining, they are of little value in preventing the wearers foot from slipping down into the toe of the shoe.
As best shown by the dotted line 8 in Fig. l, which represents the outline of the sponge, the sponge is preferably smaller in area than the heel of the sock lining so that the sponge does not come to the edge of the lining. This is so that the sock lining will cover the edge of the cushion in the nished shoe, as illustrated in Fig. 2 which shows the back edge 8 of the cushion covered by the sock lining. This enhances the appearance of the shoe.
Figure 2 is intended to represent any typical shoe construction. It includes the sole 10, the wooden portion 11 of the heel which may be of any desired height, with a lift 12 attached to the bottom of it. The shoe is merely representative of the many designs of ladies shoes and is not intended to4 limit the scope of the claims. It shows the shoe upper 13 which encloses the instep of the foot, and in this particular design the toes are all exposed. The strap 14 passes around the heel. In such shoes the tendency is for the ladys heel to separate from the bottom of the wearers foot as she takes a step. The cushion reduces or eliminates such separations.
Figure 2 shows a leather or plastic sheet 15 covering the wooden heel. A screw 16 passes through the sole into the heel and also several nails 17 hold the sole to the heel. Usually there are ive such nails, but the number of nails is not critical. It is not necessary that there be a screw or that there be nails in the shoe of this invention. If there are, the cushion covers irregularities formed by them in the heel portion of the shoe, and thus adds to the comfort of the wearer.
In assembling the shoe the cushion is preferably first cemented tothe underside ofthe heel ofthe sock lining. This combination lining is then cemented to the sole.
Figure- 2 shows the sponge projections 3 extending somewhat above the level of the sock lining. This is very effective but not necessary. So long as the pressure of the heel of-'the wearer causes-contact with the cushion, the tendency of the foot to slipdowntoward the toe of the shoe is reduced or eliminated. The sock lining will usually be made of thin leather or a plastic leather substitute. The base of the'sponge, i. e. the portiony from which the projections extend, is normally about inch thiol'` and the projections are at least about as thickas the sock lining.
The drawing and description are illustrative. vention is covered in the claims which follow.
What I claim is:
l. A ladys high-style shoe which includes head-bearing metallic fastening means passing through the heel portionof the sole of the shoe into the heel and holding the heel to the sole, the heads of said fastening means forming irregularities in said heel portion, cushioning means The in positioned in the heel portion of theshoe covering said irregularities, a sock lining over the cushion, at least one raised area on the top surface of the cushion andv at least one opening in the lining complementary in arrangement and shape to said raised area With the raised area extending upwardly through the opening to at least the height of the to-p surface of the lining, and means holding the cushion and lining in said position in the shoe.
2. A ladys high-heel shoe having a sole extending throughout the heel area, a sponge heel cushion attached to said solo at the heel area, a sock liner over said cushion provided with at least one opening, and said sponge cushion being provided with a raised extention complementary to said opening in the sock lining, of sufficient height to extend through the sock lining whereby to provide an anti-slip surface on the inner foot-engaging surface of the shoe.
