United States Patent 3,138,382 HEELS AND COMPONENT TOP LIFT-POST UNITS TIEREFOR Gregorio Estrada Maya, Montreal, Quebec, Canada,

assignor, by mesne assignments, to United Shoe Machinery Corporation, Flemington, N1, a corporation of New Jersey 7 Filed Mar. 22, 1962, Ser. N 0. 181,637 11 Claims. (Cl. 36-454) This invention relates to womens high style heels and more particularly to an improved heel construction cooperative with a post secured to a top lift of the heel in the effective securement of said top lift to the heel.

In the manufacture of a high style women's heel of the Louis type, for example, it is customary to cement a one-piece plastic or leather cover to the rear and side faces of the heel as well as to the margins of the breast and the top lift receiving face of the heel, a separate breast cover or flap forming part of the attached outsole of the shoe being cemented to the breast of the heel after the attachment of the heel to the shoe.

One type of conventional heel has a top lift receiving face in which is formed a cylindrical bore, which is of uniform diameter throughout its depth and is adapted to receive a cylindrical post formed integral with and secured to a top lift, it being common practice to'inturn the lower portion of the cover cemented to the side and rear faces of the heel onto and to cement it to the top lift receiving face of the heel, said cover terminating just short of the cylindrical bore formed in said top lift receiving face. The margin of the cover which is to be inturned upon the top lift receiving face of the heel is usually manually trimmed after the application of the cover to the side and rear faces of the heel but before it has been inturned upon said top lift receiving face. In the conventional construction it is desirable that the trimmed cover shall overlie substantially the entire top lift receiving face of the heel but shall stop short of the cylindrical bore formed in such face. In order to insure that no bunching of the cover shall occur on the top lift receiving face of the heel because the cover has been trimmed too wide, there is always a tendency on the part of the operator to trim the cover so that it can be wrapped only a short distance onto the top lift receiving face of the heel and this commonly results in the cover not being effectively secured to said top lift receiving face.

Top lifts of high style heels wear out rapidly and accordingly have to be replaced frequently. Such replacement commonly results in the cover inturned upon the top lift receiving face of the heel breaking loose from the heel even back to where it has been wrapped around the margin of this face. When this occurs attempts are made upon the part of the shoe repairmen to cement the above-mentioned portion of the loose cover to the heel but this is not always satisfactory partly due to the fact that the cover does not overlie a sufficient area of the top lift receiving face of the heel and partly to the fact that the cement is not always properly distributed and/ or is not allowed to dry before the new top lift is attached to the heel and this often results in a loose cover bulge being formed in the vicinity of a margin of the top lift receiving face of the heel. Such a bulge is unsightly and after a short while results in the cover being torn in the vicinity of said bulge.

It is an object of the present invention to provide a high style heel which is of the general type above referred to and which is not subject to the above-mentioned drawbacks.

With the above objects in view applicant has provided in a heel comprising side, rear and top lift receiving faces, a cover secured to said faces, a recess formed in said 3,138,882 Patented June 30, 1964 top lift receiving face and in accordance with a feature of the present invention a top lift forced against the cover on the top lift receiving face and having secured to it a post which is force-fitted into said recess and cooperates with walls of said recess to clamp a margin of the cover against displacement.

By forming in the top lift receiving face of the heel a cover receiving recess of substantial depth the operator may trim the lower margin of the cover, as above described, with the assurance that it will overlie the entire top lift receiving face of the heel and will be received in the recess for the purpose explained. Accordingly the condition never exists where the cover is inturned only a slight distance onto the top lift receiving face of the heel with the attendant drawbacks above-mentioned. The clamping of the margin of the cover against displacement between the post, which is secured to the top lift, and the wall of the recess insures that said cover, after it has been recemented to the heel as above explained during the course of the replacement of the top lift of the heel, will remain tightly wrapped around the lower end of the heel and accordingly no unsightly bulge will be formed such as above referred to when the top lift has been replaced.

The present invention consists in the above novel feature and in novel features hereinafter disclosed, reference being had to the accompanying drawings which represent several embodiments of the invention selected for purposes of illustration, said invention being fully disclosed in the following description and claims.

In the drawings,

FIG. 1 shows in perspective a composite Louis heel to which a cover has been secured, said heel being broken away to show a lower metal shank portion thereof and to show the attachment of said shank portion to an upper wood or plastic heel seat portion of the heel;

FIG. 2 is a section on the line IIII of FIG. 1', 7

FIG. 3 is a section similar to FIG. 2 but showing the heel before inserting a post, which is secured to a top lift of the heel, into a stepped recess or bore formed in a top lift'receiving face of the heel;

FIG. 4 shows the post, which is secured to the top lift, in the process of being force-fitted into the recess or bore formed in the top lift receiving face of the heel, a stepped base portion of said post being illustrated as starting to wipe a margin of the cover, which has been applied to the top lift receiving face of the heel, into an entrance or counterbored portion of said recess;

FIG. 5 illustrates a top lift which is made of plastic and has secured to it a metal post a head of which has the top lift molded onto it;

FIG. 6 is a view corresponding to FIG. 2 but showing a post which is secured to the top lift and is of the same diameter throughout its length;

FIG. 7 is a View similar to FIG. 2 but showing a heel provided with a countersunk recess instead of with a stepped or counterbored recess;

FIG. 8 is a view corresponding to FIG. 2 and illustrating a lower or shank portion of a wood or plastic heel into a bore of which a metal dowel has been driven, said dowel having its outer end in alinement with a top lift receiving face of the heel and having formed in said end a recess or bore similar to the corresponding bore illustrated in FIGS. 2, 3 and 4, a post which is attached to a top lift of the heel and is similar to the post in FIG. 2 being driven into the recess formed in the dowel; and

FIG. 9 shows a lower or shank portion of a wood or plastic heel having a bore into which has been driven a metal dowel an outer end of which is spaced from a top lift receiving face of the heel and has formed in it a cylindrical recess of uniform diameter, a post attached to a top lift of the heel being generally similar to the post shown in FIG. 2 but being driven partly into the dowel receiving bore of the heel and partly into the recess of the dowel.

The present invention is described (FIGS. 14, 6 and 7) as embodied in a high style heel 20 comprising a shank or lower portion 22 which is made of aluminum for example, and which has an upper ledge face 24 (FIG. 1) and a longitudinally ridged spool 26 projecting height- Wise from the central portion of said ledge face, and a wood or plastic heel seat block 28 a lower face of which has formed in it a hole 30 into which the spool of the metal shank or lower portion of the heel is force-fitted. The invention is also described (FIGS. 8 and 9) as embodied in high stylewood or plastic heels 32, 34 which are generally similar in shape to the heel 20 and top lift receiving faces 36, 38 of which are provided with bores 40, 42 respectively in which dowels 44, 46 are pressfitted. The heel 20 has applied to it a leather or plastic cover 48 which is first cemented to the rear and side faces of the heel and after being trimmed manually by the use of scissors (not shown) is inturned upon and cemented to a top lift receiving face 47 of the heel as well as to margins of the breast 50 and the attaching or cup face 51 of the heel. The margin of the portion of the cover 48 inturned upon the top lift receiving face 47 of the heel may or may not be beveled in accordance with the manufacturers practice. The entire breast 50 of the heel 20, including that portion to which the inturned margins of the cover 48 have been applied, is subsequently covered by a heel breast covering flap (not shown) which is split from and forms part of the rear portion of an outsole (not shown) of a shoe to which the heel is attached, said flap usually being cemented to the breast of the heel after the attachment of the heel to the shoe and usually having its end trimmed flush with the top lift receiving face 47 of said heel.

Having in view the difficulties encountered in the securing of the cover 48 to the lower end of the heel, as outlined in the above statement of invention, the top lift receiving face 47 of the heel disclosed in FIGS. 1-4 has formed in its central portion a bore or recess 52 which has a stepped entrance portion 52a of relatively large diameter and accordingly large cross sectional area, and an inner portion 52b which is of relatively small diameter and accordingly small cross sectional area. The heel 20 has secured to it a plastic top lift-post unit 54 comprising a top lift 56 formed integral with a post or stem 58 having a cylindrical outer end portion 58a, which may be force-fitted into the inner portion 52b of the recess or bore 52, and a cylindrical stepped base portion 58b terminating in a circular corner, the periphery of said base portion being spaced slightly from a wall defining the entrance portion 52a of the bore 52 formed in the heel.

- The cover 48 in its application to the heel 20 is commonly manually trimmed by the use of scissors (not shown) at the time it is projecting beyond the rim of the top lift receiving face 47 of the heel (see dash-line position of the cover margin in FIG. 3) and is thereafter inturned upon and adhesively secured by the use of cement, for example, to said top lift receiving face, the margin of the cover overlying a portion of the recess 52 as shown in FIG. 3. The outer end portion 58a of the post 58 of the top lift-post unit 54 is then force-fitted into the inner portion 52b of the recess 52 and the corner of the stepped base portion 58b of the post wipes, as best shown in FIG. 4, the already inturned margin of the cover under substantial pressure against the wall of the entrance portion 52a of the recess. As the top lift-post unit 54 is being applied to the heel 20, the periphery of the base portion 58b of the post 58 cooperates with the wall of the entrance portion 52a of the recess 52 to hold the cover securely in place, the cover margin being tensioned during this process. When the top lift 56 has been forced against the portion of the cover 48 upon the top lift receiving face 47 of the heel 20, the stepped base portion 58b of the post 58 will have tensioned the cover margin and will have secured it firmly in place against the wall of the entrance portion 52a of the bore.

When the top lift-post unit 54 has to be replaced in order to change a worn out top lift 56, the repairman immediately after applying, cement to the inner face of the cover 48 (where the cover has separated from the lower end portions of the side and rear faces of the heel 28 and from the top lift receiving face 47 of the heel) and manually applying the cover to these faces presses the post 58 of the top lift-post unit 54 into the recess 52 formed in the heel, the outer end portion 58a of the post being drive-fitted into the inner portion 52b of the recess and the stepped base portion 58b of the post tensioning the margin of the cover about the top lift receiving face of the heel as it presses with a wiping action, the cover against the wall of the entrance portion 52a of the bore, the top lift finally being forced with substantial pressure against the cover of said top lift receiving face.

It has been found that a press-fit is sufiicient to hold the top lift-post unit 54 in place on the heel 20 but in order further to insure that the post or stem 58 of said unit shall be securely attached to the heel, a nail 60 is preferably driven into an undersized bore 61 extending along the axis of the top lift-post unit whereby to cause said post to expand so that it will be forced with additional pressure against the walls of the recess 52.

Instead of providing the integral plastic top-lift post unit 54, a post 62 (FIG. 5) of a modified top lift-post unit 64 may be made of aluminum, for example, in which case a plastic top lift 66 is molded onto a head 62a of said post.

In FIG. 6 there is shown a modified embodiment of the invention comprising an integral plastic top lift-post unit 68 including a post 70 which is cylindrical throughout its length. In such a construction the post 70 does not have a stepped base portion corresponding to the stepped base portion 58b of the top lift-post unit 54. The post 70 of the top lift-post unit 68 is press-fitted into an inner portion 72 of a stepped bore of a recess 74 similar to the recess 52, an inturned margin of the cover 48 of the heel being pressed against a wall, which defines an entrance portion 76 of the recess, by the peripheral face of said post. The construction illustrated in FIGS. 1 to 4 is considered preferable to the construction illustrated in FIG. 6 since the top lift-post unit 54 can be secured quicker and more effectively to the heel 20 than can the top lift-post unit 68.

FIG. 7 illustrates an embodiment of the invention in which an entrance portion 78 of a recess 80 formed in the top lift receiving face 47 of the heel 20 is formed by countersinking instead of by counterboring the margin of the cover 48 being held in place by a top lift-post unit 68a. Such a construction has special utility where the margin of the cover 48 has been beveled.

In the manufacture of high style wood or plastic heels 32 such as illustrated in FIG. 8 the shank or lower portion of the heel has formed in it the cylindrical bore 40 and into said bore is driven the metal dowel 44 which is prevented from rotating in the heel by ridges or flutings (not shown) formed on the periphery of said dowel. The dowel 44 is driven into the bore 40 of the heel 32 until an outer end of the dowel is in register with the top lift receiving face 36 of the heel, said outer end of the dowel in fact constituting part of the top lift receiving face of the composite heel. The outer end of the dowel 44 has formed in it a recess or bore 82 which is similar to the stepped bore or recess 52 of the embodiment illustrated in FIGS. 1-4, and comprises an entrance portion 82a of relatively large diameter and an inner portion 82b of relatively small diameter, a post 84 of a top lift-post unit 86, which is substantially identical with the top lift-post unit 54, being pressed into the recess 82 as above explained in connection with the first described embodiment, and forcing against a wall constituting said entrance portion 82a of the recess 82 the margins of a cover 88 adhesively secured to side, rear and top lift receiving faces of the heel 44 which is of the same general shape of the heel 20 illustrated in FIG. 1. As above explained, the post 84 of the top lift-post unit 86 may be forced with additional pressure against the walls of the stepped or counterbored recess 82 by the use of a nail (not shown) driven in the manner illustrated in FIG. 2 into the post pressed into its operating position in the composite heel.

In the modified form shown in FIG. 9 there is illustrated the heel 34 having formed in it the bore 42 into which has been driven the metal dowel 46 in the outer face of which is formed a cylindrical hole, recess or bore 92. It will be noted that the outer end of the dowel is spaced a considerable distance from the top lift receiving face 38 of the heel 34, the upper end portion of a wall of the bore 42 and the outer end of the dowel 46 forming a cavity 94 corresponding generally in size and shape to the entrance portion 52a of the bore or recess 52 of the embodiment disclosed in FIGS. l4. When an end portion 96a of a post 96 of a top lift-post unit 93 is forced into the bore 92 of the dowel 42 a base or step portion 96b of said post forces a margin of a cover 100, which has been adhesively secured to side, rear and top lift receiving faces of the heel, against the upper end of the wall of the dowel receiving bore 42 in the heel. If desirable a nail 60 such as shown in FIG. 2 of the drawings may be driven into the top lift post unit 93 for the purpose of further insuring that this unit will be securely attached to the heel.
