INVENTOR.

2022 fled e 71m 7 wa ATTORN EY United States Patent ftice 2,908,983 Patented Oct..20, 1959 SELF ROTATABLE AND REPLACEABLE HEEL Aaron Berke, New York, NY. V Application September 19, 1958, Serial No. 762,103

' 2 Claims. (Cl. 36-39) I have invented an improvement in heels for shoes; especially a heel having a part or member which can be replaced with a minimum of mechanical effort, without implements or tools when it is deformed because of prolonged use. I

An object of the invention is to provide a heel having a replaceable member which is so attached to the body of the heel on a shoe that it will revolve continually bit by bit, as the wearer of the shoe takes successive steps, thus bringing a small separate portion of the surface of said member into position at each step, and distributing the wear due to the friction of the heel against the sidewalk or other surface evenly over the entire periphery of said member. Hence erosion at any particular part of the replaceable member is thus avoided. The heel thus retains its shape, in addition and walking is made easier and more comfortable.

As is well known, heels on shoes usually wear down at the back, and the wear is not confined to the middle of the heel at the rear portion thereof. Instead, the erosive effect is more pronounced along one side of the heel; in most cases the outer side at the rear end. Such a heel thus not only becomes unsightly, but also it imposes stresses upon the foot of the wearer, and often very troublesome anatomical eifects on the bones of the foot and leg are entailed.

My invention eliminates these drawbacks by providing a heel with a replaceable member, so connected to the heel that not only can it be easily replaced when worn away with use, but also is united to the heel in such a way that it can turn by degrees, thus always presenting a different area to the part of the heel that receives most of the abrasive action. The erosion or wearing away of the heel is thus spread over the entire outline of the replaceable member, and the height of the heel remains substantially constant for virtually the whole length of the rear edge on both sides of the shoe to which the heel is attached. All stresses on the wearers foot are thus eliminated.

These and other objects and the complete advantages of my improvement are clearly set forth hereinafter, and

the novel characteristics are defined in the appended claims. The drawings illustrate an embodiment of my invention, but this disclosure is by way of example only, and changes'in various respects can be made without departure or deviation from the general design in which the invention resides.

On the drawings:

Figure l is a side view of a cushion heel with a rotatable and replaceable member attached to the rear portion thereof.

Figure 2 is a view in cross-section of the replaceable member.

Figure 3 is a bottom plan of the heel that is shown in- Figure 4 is a bottom plans of the portion of the replaceable member of the heel shown in Figure 2. Figure 5 is a view similar to Figure 1 showing the replaceable member in full side elevation. Referring first to Figures 1 to 4, I indicate at 1 the part of the outer sole of the shoe having at the rear end a heel comprising a

thick front portion

2, a reduced relatively

thin extension

3, and a

replaceable member

4, which is substantially circular in outline. The

high part

2 of the heel is concave on the sideadjacent the

member

4,

' so as to conform to the shape of this member as indicated When the

section

4 is joined to the heel, it lies under the lower face of the

extension

3.' It. is united to the heel with a thin layer of leather or-

other material

6 between the upper face of the

member

4 and the lower face of the

extension

3; and as the

member

4 is generally made of some cushioning substance or material, such as rubber, the weight of the wearer of the shoe as he lets his full weight come down upon it, usually presses the

member

4 more or less forcibly against the

layer

6. But just before this, as the heel engages the'surface on which the wearer of the shoe is treading, the

replaceable member

4 is usually rotated through a short are generally in a forward direction, along the edge at the outer side of the shoe. This partial rotation, which is repeated from step to'step,

brings a new part of the

member

4 into position at the point where the most wear takes place, and the erosion wear is thus evenly distributed over the entire outline of the member, besides giving the walker greater comfort and freedom from the tiring effects that he would sooner or later otherwise feel, if the

member

4 remained stationary .and did not rotate at all.

To attach the

member

4 to the reduced portion of the

heel

3, a

stud

9 is made fast to the

layer

6 which is secured to the

extension

3. This

stud

9 has an enlarged

rounded head

10, the edge of which forms an extended shoulder with the

stud

9; and the

member

4 has a

central cavity

11 with an incut groove forming a

shoulder

12 at its inner end. As the

member

4 will stretch, it can be easily forced against the

layer

6 so that the

stud

9 will enter the

cavity

11, which is no wider than the thickness of the

stud

9, but less wide than the

head

10, and the portions around the

aperture

11 will stretch and permit the

head

10 to enter the

groove

12 at the inner end of the

cavity

11, and the shoulder on the head will engage with the

incut shoulder

12 of the

member

4. The

member

4 is thus free to rotate and whenever it should be replaced, it can easily be pulled 01f the

stud

9; but in ordinary use it will remain aflixed rotatably to the

layer

6.

The end or outer surface of the

member

4 is provided with a

radial ribs

13 extending outward from a

central projection

14. The spaces between these

ribs

14 are open around the circumference of the

member

4, so that in ordinary use the under-surface of the

member

4 cannot be pressed against the surface of the walk and stick thereto by vacuum-cup efiect.

The face of the

layer

6 adjacent the

member

4 bears a

metal washer

15 surrounding the

stud

9. On the opposite face of this layer is a

washer

16, against which the adjacent end of the stud is riveted, as shown at 19. The layer may be nailed or otherwise afiixed to the

section

3 around the

stud

9. The

layer

6 is firmly attached to the

thin extension

3 by nails or other fastening means and it holds the

stud

9 firmly and tightly in position. The

thin extension

3 may be recessed on its outer face to provide a seat for the

stud

9, if desired.

The stud is afiixed to the

layer

6, which is between the two

washers

15 and 16. This washer is therefore spaced slightly from the

member

4 so that, when the weight of the wearer of the shoe is pressed down upon the

member

4, this member is not only free to rotate but can bend slightly against the

layer

6, and as this

layer

6 is of leather, which is flexible, the. layer can be. bentagainst the

extension

3. This construction thus adds to the cushioning effect of the material of which the

member

4 is made; the stud- 9 being secured. to the

layer

6 and'this layer being secured to the

extension

3,. both the stud and the layer are thus tightly affixed to the heel and the

member

4 can be pulled oif for replacement and a new member attached easily and quickly, without detaching or loosening the stud.

' Having described my invention, what I believe to be new is:

l. A heel having a relatively thin extension adjacent its rear end, a layer disposed under said extension, a stud in said layer and projecting'from the lower surface there of, said stud having a head on its upper end and a washer thereon adjacent said head, the washer and head being located'between the upper face of said layer and said extension, a replaceable yieldable member adjacent the lower face of saidlayer, said stud'also having an enlarged head with surrounding shoulder projecting sideways from the stud at its lower end, a second Washer surrounding said stud adjacent its lower end, but spaced from said enlarged head, the layer being located between said washers, the layer being secured to said extension, said member having a cavity to receive the lower end of said stud and be detachably secured to said layer and extension, and free to rotate automatically at each step taken by the wearer of the shoe, said cavity having a relatively large recess with an undercut shoulder at the inner end of said cavity, the enlarged head of said stud fitting said recess with the said enlarged head engaging said shoulder, said member having a central projection and radial ribs on its lower surface.

2. A heel having a relatively thin extension adjacent its rear end, a stud secured to the heel adjacent said extension, and projecting below the extension, said stud having a head on its upper end and a washer thereon under said head, the washer and head being located adjacent said extension, a replaceable yieldable member adjacent the lower face of said extension, said stud also having an enlargedheadwith surrounding shoulder projecting sideways from the stud at its lower end, a second washer surrounding said stud adjacent its lower end, but spaced from said enlarged head, said member havingv a cavity closed on the outer face of said member to receive the lower end of said stud and be detachably secured to said extension, and free to rotate automatically at each step taken by the wearer of the shoe, said cavity having a relatively large recess with an undercut shoulder at the inner end. of said cavity, the enlarged head of said. stud fitting said recess with the said enlarged head engaging said shoulder, said member having a central projection and radial ribs on its lower surface.
