ARCH SUPPORT AND INTERLOCKED SHOE HEEL POCKET Filed Nov. 50, 1951 INVENTOR. J05EPH h. EVE/EfiTOAW A Tree/vs Patented May 11, 1954 UNITED STATES PATENT OFFICE ARCH SUPPORT AND INTERLOCKED SHOE HEEL POCKET Joseph H. Everston, Los Angeles, Calif. Application November 30, 1951, Serial No. 259,261

8 Claims. 1

This invention relates to an arch support and interlocked shoe heel pocket.

With particular reference to shoes which are open at the back, it has been proposed to provide a pocket at the heel seat in which an arch support may be inserted to conceal its edges and prevent it from slipping rearwardly. l'here has been no means for accomplishing this result in a previously manufactured shoe, nor any means of positively preventing the arch support from becoming forwardly displaced. The present invention provides an interlocking construction which can be incorporated with no substantial added expense either in the fabrication of the arch support or the shoe. Desirably, the pocket is narrowed at its mouth and the arch support is transversely notched adjacent its side margin in registry with the mouth of the pocket to preclude movement in either direction. The present inv-ention further contemplates a pocket-forming heel pad which is either integral with, or unitarily assembled upon, a sock lining to constitute a separate article of manufacture which may be incorporated in new shoes or in shoes previously constructed.

Fig. 10 is a slightly modified form of the device of Fig. 8 and with which the arch support of Fig. 9 is alternatively usable.

Fig. 11 is a View in perspective on an enlarged scale showing a slightly modified embodiment of Fig. 1.

The invention is not concerned with the forepart of the shoe, nor broadly with its general construction, both lasted and slip lasted embodimerits being illustrated.

The lasted shoe shown in Figs. 1 and 2 has the conventional sole H, heel H0, insole I2 and upper it open at the rear except for the ankleencircling strap. The insole may have a margina1 binding l'iil. The sock lining !4 may be cemented in place or otherwise secured.

In accordance with the invention, a pocketforming heel pad I5 is used. The heel pad is desirably co-extensive, or nearly so, with the heel seat portion of the shoe. The heel pad is connected in any suitable way or by any appropriate fastening means to a full or partial sock lining or other suitable part of the heel portion of the shoe and may cover or replace or expose the lining, typical exemplifications being herein disclosed.

In the exemplification shown in Fig. l and Fig. 2, it is preferred that the pocket-forming heel pad id have its side and rear edges inwardly turned about the margins of the sock lining and cemented therebeneath (Fig. 2) to bind such margins and to constitute the sock lining l4 and heel pad [5 a separate and unitary article of manufacture which may be sold as such and installed by cementing or otherwise in previously manufactured shoes as well as in shoes in process of manufacture. The forward margin is of the heel pad is, of course, free or nearly entirely free to permit the introduction or removal of the rear end of a longitudinal-arch support such as that shown at 29.

As shown in Fig. 11, the downwardly and inwardly turned side and rear margins I54 of the heel pad l53 may be anchored by the cement H3 to the upper surface of the sock lining I43 instead of being extended about its margins and connected with its lower surface as in Fig. 1. Fig. 11 also shows a single brad used at I94 as a means of limiting the width of the pocket mouth at the forward free margin it of the pocket-forming heel pad Q53.

Whether the pocket-forming heel pad is cemented (Fig. 1) or otherwise mechanically connected in place, as by the stitches or other connectors ill of Fig. 3, in any case the stitch or staple or brad connections ll may be used at the is flattened out and the notches receive the pocket-restricting means at I! to effect aninterlock which precludes movement of the arch support in any direction. The restricting means may obviously be used, if desired, in the construction of Fig. 1 and Fig. Yet the arch support may be readily removed, when the shoe is not being worn, by longitudinally channelling it to withdraw the side margins of its heel portions into the space between the two terminal lines of stitching from the notches.

The-arch support 23. may be of any desired form; Preferably it includes a top or cover ply 2i and a cushion 22. At least at the rear, there is desirably also a slip ply 23 (see Fig. 6) to facilitate the introduction of the arch support into the socket. If the sponge rubber or other cushion were exposed at the bottom of the arch support,

its high co-efficient of friction would make dif-' ficult the tasl; of positioning the device in the pocket. The slip ply 23 rides smoothly on any underlying surface, such as those of the sock lining M or insole 12.

In the slip lasted construction shown in Fig. 6, the platform as intervenes between sole 3! and the insole or sock. lining 32. The pocket-forming heel'pad 33 has its side and rear margins turned downwardly at as and inwardly between the inturned margins of the sock lining 32 and the heel wrapper 35, all such margins being stitched together at 36.

In the construction shown in Fig. 7, the pocketforming heel pad I59 is unitary with sock lining E4 and is slit at I66 near its forward margin to receive the laterally notched arch support 20. The pad portions beyond the end of the slit form. the restriction which is received into the notches 25. In this construction, the extension of the stitching at it is not required and the slit i60 may be formed in the same operation in which the heel pad is diecut.

In the construction shown in Fig. 9, the arch support 26'. has only a single slit at 25! in one of its side margins. It may have a heel portion, as in Figs. 1 to '7, or may terminate at 292, immediately behind the slit 25!. The heel portion may be omitted from any of the arch supports shown. In the shoe with which this arch support is used, the heel pad may be of entirely conventional form, being stitched at III to the heel seat (Fig. 3) and having its forward margin at (6 unrestrictedly open to receive and lap the rear end 202 of the arch support 29!. Immediately forward of the heel pad, I provide an orthopedic lift 26 at the inside of the shoe below the scaphoid of the wearer. This lift may be anchored by an extension at I12 of the stitching used to secure the heel pad 5! to the sock lining M. The lift at 25 supplements the conformation of the arch support to throw to the outside of the shoe the weight of the wearers foot, thus contributing to better balance. It is covered, in use, bythe arch support. Under weight of the 4 wearers foot, the heel ortion of the arch support is marginally locked behind the lift 26.

As suggested in Fig. 10, the lift 262 may be made integral with the heel pad 152 and the stitching I'll may be extended completely around the lift 262 as indicated at 113. In this construction, the margin I62 which gives access to the pocket is restricted by the width of the lift 262. The same arch support shown at 201 in Fig. 9 (or that shown in Fig. 4) may be used with this device, but will have to be manipulated as above described to insert it into the restricted opening of the pocket.

I claim:

1. Ina shoe having a heel seat portion, the combination with a heel ply marginally connccted at its side and rear with said portion and having an open forward margin, said heel ply and heel seat providing .a forwardly opening pocket, of an arch support having a forward longitudinal arch'supporting portion substantially co-extensivc in width with the shoe and a rear portion immediately behind said arch supporting portion and disposed in said pocket underlying said h el ply, and means interlocking the forward margin of the heel ply and the rear portion of the arch support whereby to restrain disengagement of the arch support from beneath the heel ply.
