8 Claims.

This invention relates to heels for womens shoes and more particularly relates to fabricated metal heel arrangements of simplified self-reenforcing construction which are light in weight.

Among the objects of the present invention is to provide metallic heels for ladies shoes, suitable ior economic mass production; formed of fiat metallic sheets, using ordinary sheet metal fabricating or extrusion operations; self-reenforced when assembled for strength and lightness in weight; and well appearing and attractive for ornamental effects.

These and other objects and features of the invention will appear from the subjoined detailed description of specific embodiments thereof illustrated in the accompanying drawings, in

which:

Figure 1 illustrates one form which the unitary heel construction of the invention may assume in practice, assembled on a shoe.

Figure 2 is a perspective illustration of the unitary heel assembly of Figure 1.

Figure 3 is a dissembled view ofthe heel of Figures 1 and 2.

Figure 4 is a development of a metallic sheet comprising the bent-up portion of the heel of Figures 1 to 3. V

Figure 5 is a modified plan view of the heel portion corresponding to Figure 4.

Figure 6 is a perspective view of a modified heel, assembled on a shoe.

Figure 7 is a dissembled View of the heel of Figure 6.

Figure 8 is a plan view of a fabricated central portion of the heel of Figures 6 and 7.

Figure 9 is a perspective view of still a further form of the metallic heel of the invention.

Figure 10 is a plan view in section along lines lit-I0 of Figure 9.

Figure 11 is disassembled view of the heel of Figure 9.

Figure 12 is a vertical cross-sectional view through the heel construction of Figure 9, illustrating a preferred way of attaching the heel to a the body of the shoe.

Figure 13 is an enlarged detailed sectional view through the preferred heel attaching means of Figure 11.

Referring to Figure 1, I: illustrate a simple rigid heel construction comprising i two vertical portions 20, 2| joined by an intermediate integral section 22 and anupper plate 23, to which flanges 24 and 25 at the top of members 20 and 2l'respectively are secured. A leather or rubber lift or .heel portion 26 is secured to the bottom of the heel body.

A perspective view of the unitary heel construction in Figure 1 is shown in Figure 2. Plate 23 is attached to the bottom 21 of the shoe and is either fiat or has a curvature corresponding to the shape of coacting sole 21. The upright sup-- porting members 20, 2| taper outwardly longitudinally and are bowed transversely from the relatively narrow bottom portion 22 to the larger upper plate 23.

A dissembled View of the heel of Figures. 1 and 2 is shown in Figure 3, wherein top plate 23 is separated from the fabricated portion 20, 2!, 22.

Flanges 24, 25 are contiguous with the upright sections 20, 2| respectively, and are welded, brazed, riveted or otherwise secured with the metallic plate 23 to form a 'rigid-self-supporting heel assembly.

The central body of the heel of Figures 1 to 3 is formed of a flat metallic sheet, as illustrated-in Figure 4. The corresponding sections of the heel body are represented by the corresponding numerals, and are separated by dotted lines, which represent bending regions for fabrications. The shape of the metallic sheet is such that when bent on the dotted lines defining the bending zones, the heel body illustrated in Figure 3 is formed; I

Figure 5 shows an alternate arrangement for constructing the heel of Figures 1 to 3. In this case, flange 25 is omitted, and the upper plate 23 is integral with the unitary central sheet, as shown at 23'. In this case, by bending along the dotted lines of Figure 5 and joining flange 24 with the corresponding edge of member 23, a unitary heel construction corresponding to Figure 2 results. The lift 26 shown in Figures 1 and 2 is suitably securedtowthe bottom of central portion 22 to complete the heel assembly.

The heel construction described in connection with Figs. 1 to 5, as well as those to be described hereinafter, have a common factor in being unitary with respect to the remaining shoe; being formed of flat metallic sheets cut, bent, and otherwise fabricated by simple standard mass production methods; and assembled in a hollow or open construction which is self-strengthening and has a pleasing and ornamental appearance.

.Figures 6, 7- and 8 show another form which my invention may assume in practice. Figure 6. is a perspective view of heel 30 secured'to the rear portion of sole 3| of the body of a shoe. Heel 30 comprisesv a central member 32 of crisscross form giving a definite ornamental effect,

and which is secured at the top to a metallic coupling plate 33. A leather or rubber heel 34 is suitably secured directly to the bottom of central portion 32, or may be joined to an intermediate metallic plate secured to portion 32.

Figure 7 is a disassembled view of heel 30 showing coupling plate 33 and heel section 34 separated from the fabricated body portion 32.

Flanges 35 extending from the bottom sections of portions 32 are used to join central body '32 with heel 34. fCorresponding flanges 36 at the top. portion of member 32 are bent over at substanin an economical manner in commercial production.

Although I have referred to spot'welding or brazing with respect to the flanges, such as 2425 and 36 and the like, it is within the province of this invention to eliminate the flanges and to braze or weld the edges of the intermediate sections directly to the upper or lower heel plates, as the case may be.

Although I have described the formation of the heel of sheet metal or the like, it is within the province of this invention to form the heel of plastic or likenon-metallic materials.

, Although I have described preferred arrangements for carrying out my present invention, it

' is obvious that various changes and modifications maybe made to the details of construction without departing from the general spirit of the inup to that form. Openings 3! and 38 therein form the centralopenings of the heel, enhancing the, design and ornamental appearance of the heel. Portions39 are bent over in'a flangeform to serve as a ree'nforcing means for the heel when.

assembled, assh'own in Figures 6 and 7; The assembled. heel is a unitaryconstructiomlight in weight andhaving ample strength in service;

Figures 4 to 12 illustrate still a further. form which my invention may assume'in practice. In

this example, heel is formed of two interlocked vertical members 5| and 52 joined to-a coupling piece 53 and a heel section 54 at'the bottom of which lift 55 is secured. The dissembled'view,

Figure 10, of heel 55 clearlyillustrates the inter-.

locked assembly thereof. I Uprights 5| and 52 have coacting slotted sections 56 and 57 whichare slid together forthe'interlocking. 7

Upper flanges 58, 59, 60 and 6| form acommon plane when upright, members 5| and 52 are interlocked. in the assembled form shown in Figure 9. Flange sections 58 to 3| are accordingly readily riveted, welded or otherwise joined to heel coupling piece 53 due totheir'common plane. Similarly, bottom flanges52, 63, 64, form a common plane for securing to metallic heel piece 54. construction of pleasant appearance of rigid selfsupporting, self-strengthening design.

A preferred method of assembling the metallic heels of the invention to the body of theshoe is illustrated in Figures 11' and 12, specifically in connection withheel 53 of Figures 9 .and 10.

Heel plate 53 is secured to shoe 10 by rivets 1|. Four rivets, such'as l I, passing through openings 12 shown in plate 53 of Figure 11, are generally 'sufiicient. Figure '12 is an' enlarged sectional view through a portion of the rivet section show- 2 ing rivet 7| ,holding-heelplate 53together with shoe section 10 comprisinga plurality of layers including an inner sole, fiber or leather counterlining, and other usual shoe layers. 1 V The outer edge 13 of heel plate 53 is curvedover, resulting in its edge digging into the body of the shoe 10 to obtain a firm grip. A suitable padding or lining 14 is placed inside the heel section of the shoe, as shown in Figure 12, to cover up the inner heads of 'rivets H. i

, The heel plate of the unitary shoe ofthe'in- .vention need only be made-in small, medium and large sizes and withaminimum degreefof curvature. Its edge, corresponding to edge 53, is forced upward by a U-anvil to .flt closeto the shoeand firmlylgrip it. 'Another method is to employ heel plates of different sizes, leaving the heel of the shoe the same size. In this manner,

The assembled metallic heel forms a unitary vention as set forth in the appended claims.
