United States Patent 3,087,264 ENTERCHANGEABLE TURNABLE HEELS William McKinley, 1402 Ave. 1, Brooklyn, Filed Mar. 18, 1960, Ser. No. 15, 085

1 Claim. (Ci. Sid-35) This invention is directed at an improved turnable heel and sole construction, for a shoe.

According to the invention there is provided a heel or sole body for a shoe made of rubber, plastic, fiber or composition material. The body is provided with a cavity for receiving a turnable rubber member adapted to be secured in place on a shoe by a core or plug having tapered sides. In one form of the invention, the core itself is adapted to be turned to equalize wear thereon. The outer surfaces of the members constituting the sole or heel may be ribbed or corrugated.

It is therefore one object of the invention to provide a heel or sole body for a shoe having a cavity adapted to receive an annular ring, the ring having an inner tapered wall adapted to abut a mating tapered wall of a circular core whch fits within the ring and holds it on a shoe.

A further object is to provide a sole or heel structure for a shoe, with a turn-able ring adapted to: be rotated as it wears at one point so that a fresh portion may be disposed at the point of greatest wear and impact of the shoe.

Still another object is to provide a sole body with a plurality of turnable rings and cores having tapered walls.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a side elevational view of a portion of a shoe with a heel embodying the invention mounted thereon.

FIG. 2 is a bottom plan view of the portion of the shoe of FIG. 1.

FIG. 3 is a vertical sectional view taken on line 3--3 of FIG. 2., on an enlarged scale.

FIG. 4 is an exploded perspective view of the components of the heel of FIGS. 1-3, parts being omitted.

FIG. 5 is a bottom plan view of another heel construction according to the invention.

FIG. 6 is an exploded side elevational view of the ring and core of the heel of FIG. 5.

Referring to FIGS. 1-4, there is shown a heel structure 20 including a flat body 22 formed with a partially cylindrical cutout or cavity 24 extending through more than 180 circumferentially. Within this cavity and coplanar with the body 22 fits a rubber ring 26. This ring is a flat annular member having an outer cylindrical wall 28 which fits snugly against the curved wall 24 of the heel body. The ring has a central hole 30 whose wall 32 flares outwardly from top to bottom of the ring.

A circular core or plug 34 having a corresponding flaring wall 36 fits within and abuts wall 32 of the ring. Nails 38 may be driven through holes 40 preformed in the core for securing the core to the heel base 42 of shoe 44. Nails 39 will secure the body 22 to base 42. A screw ice 46 may be threaded through the ring and screwed into the shoe base for preventing the ring from turning during normal wear. This screw can be loosened and the ring can be turned by finger pressure on core 34 so that when the outer portion of the ring exposed beyond the finger portions 25 of the heel body is worn, the ring can be turned around to expose a fresh unworn portion for renewing the life of the heel. A thin metal foil sheet 23 or a rubber sheet can be inserted between heel structure 20 and heel base 42, to waterproof the heel. The sheet 23 is formed with a central opening 27, and may be fastened to the ring 26 by cement or the like.

The nails 33 extend through the opening 27 of the sheet 23 so that the core 34 can be rotated slightly. A screw 29 extends through the center of the core and into the base 42 and may be set upon to hold the core in adjusted position.

The structure of heel 22 in FIGS. 5 and 6 is similar to that of structure 20 except that the ring 26 and core 3:4 have outer ribbed or corrugated surfaces '33, 35, respectively. Otherwise the ring and core have the same structure as that of members 26 and 34 and corresponding parts are identically numbered.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:

A heel structure for a shoe comprising a flat leather base of semicircular shape, a flat rubber body of substantially the same shape having one end cut away providing a semicircular cavity therein, means securing the rubber body to the base, a rubber ring member fitted in said cavity, said ring member having a central aperture, a waterproof metal foil sheet secured to the inner surface of the ring, said sheet having a central aperture smaller in diameter than the diameter of the central aperture in the ring member, and a separate solid circular rubber core member fitted in the aperture of the ring and seated on the metal sheet, said core member having holes therein, fastening elements extending through the holes in said core member and through the aligned apertures in the ring and sheet into the base for yieldingly and rotatably holding the ring in position, and a screw member extending centrally through the core member and through the aligned apertures in the ring and sheet whereby the core member is secured in adjusted rotated position.
