`Claims priority, application Germany Nov. 22, 1957 '1 Claim. (Cl. .3G-35) This invention relates to the repairing of heels for all types of footwear of the kind including a heel block on which a heel plate is secured.

The object of the invention is to provide an improved combination of heel plate and heel block permitting simple and rapid removal and attachment of the heel plate.

Two embodiments of heel plate assembly in accordance with the invention art hereinafter particularly described by way of example with reference to the accompanying drawing, wherein:

Figure l shows a heel viewed from below and with a heel plate in position;

Figure 2 is a view from below of the same heel with the plate removed;

Figure 3 is a central longitudinal section of the heel shown in Figure 2;

Figure 4 is a central longitudinal section of the heel of Figure 1, with the heel plate shown as separated from the heel;

Figure 5 is a central longitudinal section of the heel of Figure 1;

Figure 6 is an underplan of a modified heel plate;

Figure 7 is a plan view of a heel plate for a small heel of a ladys shoe;

Figure 8 is an underplan View of a ladys shoe heel block adapted to receive the heel plate of Figure 7;

Figure 9 is a central section of the assembly of the heel of Figure 8, and the heel plate of Figure 7.

Referring now to Figures l to 5, there is shown a heel block 2 made up in well known manner from layers of leather or other suitable material. At the rear part, i.e. where a heel tends in practice to be most heavily stressed and worn away, there is formed an approximately semicircular step or recess into which can be fitted a correspondingly shaped heel plate 2. This heel plate is made, for example, of an isocyanate polyester resin, or any other suitable hard-wearing material which has adequate mechanical strength but is also resilient in nature. In the recess or step of the heel block 1 is disposed also a correspondingly shaped mounting plate 7, preferably made of hard impact resisting synthetic resinous plastic material, having holes to receive the usual nails 8 by which it is secured to the heel block. In the mounting plate are provided a larger approximately central aperture 6, and a plurality of other somewhat smaller apertures 5, all said apertures tapering conically towards the exterior. On the heel plate 2 are provided a tenon 4 and a plurality of tenons 3, these tenons all being cylindrical and chamfered at their free end, whereby upon application of sufiicient pressure to force the heel plate 2 against the mounting plate 7, the tenon 4 can be caused to deform slightly and enter the aperture 6, and the tenons 3 can be caused to deform slightly and enter the Fice aperture 5. When the heel plate 2 has been pressed into I overall contact with the Vmounting plate 7, the tenons 4 and 3 are fully housed in their respective apertures and, by reason of the conical tapering form of the latter and the consequent compression and deformation of the resilient tenons, the latter are very iirmly gripped and thereby lock the heel plate to the mounting plate. If required, the heel plate 2 can be separated again from the mounting plate 7 by inserting a suitable levering tool between the two and applying suicient force to drag the tenons out of their apertures. Instead of providing a separate mounting plate 7, requiring attachment to the heel block, the plate 7 may be omitted and the apertures 4 and 3 formed directly in the heel block itself.

Detachment and forcing away of the heel plate from the heel block for the purpose of renewal of the heel plate can be effected as many times as desired, the mounting plate where provided remaining on the heel block permanently.

In Fig. 6 there is shown a modified mounting plate 7a adapted to be secured by nailing into the recess a heel block and to receive a heel plate of corresponding shape, of smaller dimensions than that shown in Figs. 1 to 5, e.g. for repairing only the extreme rear end of the heel, as by a quarter rubber in known heel repair methods.

Referring now to Figs. 7, 8 and 9 which shows a so-called pencil heel, the heel block 9 has a central well or recess into which is seated a boss 10, of corresponding shape, on one face of `a mounting plate 11 secured to the heel block 9 by a suitable nail 12. The mounting plate 11 is provided with a central tapered recess 13 to receive a parallel-sided tenon 14 on a heel plate 15. The recess 13 and the tenon 14 are so shaped that the heel plate is keyed against rotation with respect to the mounting plate.

What is claimed is:

A heel for a shoe comprising a base portion formed at a plurality of lifts having a recess at its point of greatest wear, a iirst section received in said recess at its point of greatest wear having inner and outer substantially parallel faces, said rst section being adapted to be attached at the inner face thereof to the base portion and provided with a plurality of truste-conical openings extending between the faces of said lirst section with the smallest diameter of said conical openings being in the outer face of said iirst section, a second resilient section received on top of said rst section and having substantially parallel faces, a plurality of resilient cylindrical projections extending from one face of said second section and having a diameter slightly greater than' said smallest diameter of said conical openings, said projections being pressure inserted into said openings whereby said projections conform to the frusto-conical shape of said openings and secure said second section to said first section and to the base section of the heel.
