Lawson 571 ABSTRACT A shoe wear element for use on the outer surface of a heel and sole, for positioning along one edge thereof consisting of a'less than completely circular thin planar element having positioned about the peripheral 1 edge thereof a plurality of curved heel conforming wear portions together with fastening means for detachably positioning the wear element to the edge of sole and heel to permit repositioning the same element in the same location with an unworn edge in position, when the original edge portion is worn.

9 Claims, 3 Drawing Figures 1 SHOE WEAR ELEMENT This invention relates to a shoe wear element that may be added to a conventional shoe to avoid replacement of the entire heel or sole, when just one edge is worn along a small area.

The new result is accomplished by adding a novel thin planar element to the surface of a conventional heel or sole and changeably securing the same.

The object of the invention is to provide such an element with a multipositional periphery so that it can be repositioned over the wear area when the usefulness of the original position has ended. The worn area of the element may then be used as a support for maintaining the new wear absorbing area of the same element on the shoe surface.

A further object is to provide such a multipositional wear element with simple fastening means so that any shoe wearer with conventional tools present in most households can more or less instantly remove the element from a shoe and reposition the same or add an element to a shoe having a conventional'heel and sole.

Still another object is to provide the wear element with a plurality of identical curves and contours corresponding substantially to the curves and contours of the heel or sole to which the element is intended to be affixed.

Other objects are to provide the multipositional wear element 'a. with fasteners so arranged about the wear element so that the fasteners will fit into the existing fastener apertures each time the wear element is repositioned to avoid the necessity of providing new ap' ertures each'time element is repositioned; to provide amultipositional element at the same price to the public as a single position element, thus reducing the ultimate cost per wear area to a small fraction of the single unit price; c. to provide shock absorbing wear resisting elements .that are relatively inexpensive; d. that can be punched out from flat sheets thus reducing tooling costs; e.'that can be secured with nails or screws; f. that can be trimmed to make the edges exactly conform ifit should be desired; g'. that occupies only a small portion of the heel or sole area;

h. that will withstand wear for a reasonable period of time; I that is sufficiently thin so as to be comfortable when worn on the outer surface of the conventional heel or sole and; I j. to provide a shoe with a recessedarea for the element so that it need not project above the normal surface of a conventional heel or sole. These and other objects are achieved and new results accomplished as will be evident from a consideration of the shoe. wear element described hereafter, outlined in "the appended claims and illustrated in the accompanying drawing in which FIG. 1 is a plan view of a proposed multipositional wear elementmounted toa shoe; 7

FIG. 2 is aside view of the same and FIG. 3 is a similar view of a modified form of wear element installation.

Referring more in detail to the drawing and espe- I cially to FIG. 2 thereof, reference numeral 10 designates a conventional heel attached to a supporting base 12, which is mounted to a sole element 14 extending from the rear section 16 of the shoe 18, to the front toe section 20.

The heel has mounted along its rear edge a wear element 22 made of special material and having a special shape, both hereinafter describedf The wear element 22 may be fastened to the heel 10 by special metal fasteners 24, the heads 26 of which are preferably located in recess 28 in the wear area of the element to avoid contact with any supporting surface when the shoes are worn.

The element illustrated in FIG. 1 is provided with multipositional wear areas designated as 1, 2, and 3. More or less areas may be provided as desired.

The exposed edge of position 1 of FIG. 1 has a contour which follows substantially the curved contours of the rear of the heel, to avoid either a projection of the element over the rear of the heel, or a recession behind it.

When the edge of position 1 wears to a.point where the original heel surface is about-to become exposed, the edge of a screw driver may be inserted between the element and the heel to separate the two members, or the screw driver may be inserted at the rear to perform the same task. The fasteners are designed to facilitate such removal. I v

The separatedelement is then repositioned so that position 2 or 3, shown in FIG. I, may be located where position 1 was originally fastened, and the fasteners 24, inserted into the same fasteneropenings in the heel,

,where it will be found that the fasteners will frictionally retain the wear element securely. In the illustrated heel element, the three wear positions may each be exhausted before the heel element is completely replaced.

The wear element can be formed with a plurality of 4 differently shaped wear areas for protecting both the heel and toe ofa conventional shoe. Thus, the wear element illustrated in FIG. 1 may in addition to positions l, 2and 3 be provided with inbetween positions 4, 5

and 6. These latter positions are provided with contours which have smaller radii, sufficient for example to form a wear edge for the tip of the sole of the shoe. In FIG. 1, the toe edge 20 is shown provided with a similar wear element as the heel position,but with say position 4 mounted to the front toe edge to protect the same. Since the wear elements are intended to possess only a small fraction of the heel or sole areas, the same shape may be used for each end er the shoe.

Thus, the heel and toe wear elements when their respective positions have worn'to require replacement, may be interchanged with each other to extend the life of the wear element.

In FIG. 3 the heel 10a is shown provided with a recess 32 into which a wear element 22a may be'positioned. The shape of the recess follows closely the contours of the wear element. Such a construction may have valuea for those who prefer a smooth wear surface for the heel. This construction may be provided in new shoes, or shoes that are worn sufficiently to replace the heel itself. A new heel may be mounted to the shoe itself,

containing the recessed section into which the replaced heel element has been positioned.

The repositioning of the wear element in a heel provided with a recess is exactly the same as the repositioning of the heel element mounted to the original wear-surface of the heel, as in FIG. 2.

The special shape of the wear element may be seen for example in FIG. 1. It consists of a plurality of individual wear edges, each curved to follow substantially the curved contour of the edge of the heel or sole, which it is desired to protect. The curve conformation should be sufficient to avoid any extension of the wear element beyong the edge of the heel, or to avoid any inward recession that might appear unsightly. As a practical matter, little interference with the satisfactory operation of a wear element isencounteredwith a small projection or recession, so long as it protects the edge of the heel sole surface from further wear. The exposed area of the wear element is thus a small fraction of the entire heel area, since the wear element of the heel or sole is designed to directly protect only the edge of the heel or sole, and only is incidentally useful for protecting other parts of the wear element.

The materials selected for use in the wear element are characterized by being abrasion and wear resistant and with some degree of resiliency. One such a material is a urethane plastic which has been found to be long wearing and noise free when used on heels and soles when walking. Another such material is known under the trademark, Neolite.'Numerous other materials having similar qualities may be found on the market. These materials may be formed into sheets and punched into the desired form or molded into the desired shapes. The materials may be formulated with f1- bers, or other reinforcing materials if desired.

The preferred fastener is a thin, sharp nail of length sufficient to retain the wear element in place, and thin enough to facilitate entry onto and removal from the heel or sole. Screws may also be used having the foregoing characteristics. It has been found that a length of /2 inchis-adequate for the nails in use on heels.'For toes a reduced length is desirable.

It should be noted that the fasteners should be arranged on'the wear element in predesignated positions, topermit relocation of the fasteners in the same openings in the heel or sole, when the wear element is repositioned to obtain' a fresh wearing edge. The minimum number of fasteners should be used consistent with ad: equate retention of the wear element.

. The foregoing discloses and describesa replaceable,

multipositional wear element for positioning along the wearing edge of a shoe heel or sole.

The wear element preferably has an edge contour consisting of a plurality of identical curves conforming substantially to the edge of the heel and sole.it is desired to protect, to provide a trim view of the same.

The thickness of the wear element is desirably about 1/32 of an inch, although such dimensions may be varied to accommodate the needs of the wearer.

The wear element is made in planar form to fit comfortable to an'existing shoe heel or sole.

The wear element, if made of a flat material, may be positioned on the wear surface of a heel orv sole in upside down position, thus doubling the number of un worn edges on each wear element.

Since this invention is concerned only with protecting the vital edge of a heel or sole, the area of the wear element is only a small fraction of the existing wear area of the shoe. A large saving in the cost of material is thus insured over contentional types of wear elements.

It should be noted that by using fractions of curves, the area of the wear element can be sharply reduced over a circular form which would normally occupy a substantial area of the shoe heel requiring a large number of fasteners making more difficult the application of the wear element to the shoe and its repositioning. By position inbetween the heel curves, curves of sharply reduced radii for use on the edge'of soles, the life expectancy can be doubled. v

I have thus described the invention but it should be noted that the particular shape shown is only an example and that other multipositional shapes are possible and desirable and coming within the scope of the appended claims.
