7 June 18, 1957 M. ZUCKERMAN H AL SHOES Filed July 5 1, 1956 IN VEN TORS makwnv zucxznmw By LOUIS A. LONGOBR'RDI ATTORNEY United States Patent SHOES Application July 31, 1956, Serial No. 601,311

1 Claim. or. 36-42) Generically, the invention relates to ladies footwear and specifically it comprehends improvements in shoes having removable or interchangeable heels, as for example French heels.

Style is the most important factor in ladies apparel and this is especially the case in footwear, one of the largest segments of this vast industry. A highly desirable attribute of a stylish pair of womens shoes is their adaptability to blend with other parts of the apparel, viz: the dress, gloves and hat.

The instant invention comprehends improvements in the replaceable heel structure invented by Andre Perugi'a, as disclosed in a patent application No. 601,312 being filed concurrently herewith, and one object of the present invention is a shoe having a replaceable heel which may be positively locked in position on the shoe, absolutely secure against displacement, on untoward removal. Another object is the provision of a replaceable heel structure part of which is virtually an extension of the present shoe shank stiffener employed in the manufacture of ladies footwear.

Another and prime object is a ladys shoe on which the heel may be expeditiously changed to a different colored or decorated heel without undue exertion but which, when the heel has been changed and locked in position, presents the appearance of a new shoe with no visible showing of the mounting structure.

These and other objects will be manifest after a perusal of the specification, drawings and claim.

Briefly described, the invention consists in the incorporation in the shoe shank stiffener of an enlarged plate extension which is afiixed to the heel seat portion of the shoe, and beneath this is integrally mounted a support having a dovetail groove in its underside and a stop pin mounted forwardly of one end of the groove. The support, extension and insole of the shoe are cylindrically and vertically bored, while above the opening of this bore is provided a lift tab affording ready access to the bore. The replaceable or interchangeable heels are longitudinally channelled at the heel seat portion and in the channel or recess is mounted a tenon also vertically bored, said tenon adapted to be slidably received in the dovetail groove of the support and securely locked against displacement by a pin inserted into the bore from the opening beneath the lift tab. Various refinements of the invention are contemplated which will be disclosed herein.

In the drawings,

Fig. 2. Perspective view of the shoe with heel separated therefrom.

Fig. 3. Top plan view of shoe.

Fig. 4. Cross-section taken along lines 4 -4 of Fig. 3.

Fig. 5. Cross-section taken along lines 55 of Fig. 3.

In the practice of the invention there is provided a ladys shoe indicated generally at 5 having conventional upper 6, the inner marginal edges 7 of which may be 2,795,867 Patented June 18, 1957 afiixed to inner sole 9 as by nails 8. Between the inner sole 9 and outer sole 17 there is provided a shank stiffener 10 having curved lower portion 11 shown in Fig. 2 as being secured in conventional fashion to between the shank portion of the inner sole 9, filler strips 34 and outer sole 20, said stiffener having a raised or rib portion 12. The upper or rear end part of shank stiffener 11 forms what may be described as a palm 13 having a pair of side portions 14 and a rear portion 15, afiixed to the under side of the heel seat portion of shoe 5 as by fasteners 16. Integral with and depending from palm 13 is a support 17 having dovetail groove 18, and in adjacent relationship to the inner end of groove 18 is mounted stop pin 19. The outer sole 20 and filler strips 34 are cut off to form an end 21, as illustrated in Fig. 2.

The removable heel 22 has concaved heel seat rim 23 and the side and rear portions of the heel and rim 23 are covered with material which may be the same as the upper 6, or any other desired material contrasting with the upper. The medial heel seat portion of heel 22 is longitudinally recessed as at 32, in the confines of which is rigidly mounted tongue 27 as by screws 28. The sides of said tongue, it will be noted, are spaced equi-distantly from the sides of recess 32 to permit support 17 to be received within the recess 32 as tongue 27 is slidably engaged by dovetail groove 18 when heel 22 is placed on the shoe in sliding engagement therewith. Breast 25 of heel 22 is covered with a continuation of outer sole 20, and inner vertical wall 24 of the heel abuts inner end of outer sole 21 when the heel is mounted on the shoe.

The inner sole 9, palm 13 and shank stiffener 10, support 17 and tongue 27 are vertically bored to form a mating orifice 31 when the heel is fully seated, as depicted in Fig. 1, with sock, lining 29 having lift tab 30 affording access to the orifice 31 to permit the pin 33 to be placed in orifice 31 to hold the heel 22 securely positioned on the shoe against untoward displacement or movement of any kind.

The heel 22 when in seated position fits the shoe to a nicety with the concaved heel seat rim 23 snugly embracing the heel seat portion of the inner sole, and inner vertical wall 24 of heel 22 abutting inner end 21 of outer sole 20. The shoe presents no visible structure different from conventional shoes, the means for mounting the interchangeable heels being completely within the shoe.

The stop pin 19 acts as a firm stop for the inner end of tongue 27when the heel 22 is slid in place on the shoe, in addition to the stop created by the end 21 of outer sole 20.

When the description French heel is used with reference to the heel shown in the patent, it is not intended to be limitative, as it is contemplated that any type of heel for a ladys shoe may be employed, or for that matter, it is within the inventive concept that the invention might be adapted for mens footwear.

In addition, while the appellations tongue and support having a dovetail groove are given to certain structure, mortice and tenon, key and keyway and other descriptive words might be employed which are equally applicable.

The invention is not limited to the exact details of construction herein disclosed, but claim all variations thereof.

We claim:

A heel assembly for footwear including a heel having a. concaved upper rim and a longitudinal recess below said rim, an apertured key mounted in said recess, a sole structure including at least an inner sole, an outer sole and a sock lining, an inflexible shank stiffener interposed between the inner sole and outer sole having an enlarged extension having side and rear portions, said extension afii'xed to the heel section of the shoe and forming a platelike palm, an apertured keyway mating said key depending from said palm between said side and rear portions and having a stop adjacent the inner end of the keyway, the sock lining having a lift tab, afiording access to the 5 apertured keyway, an aperture in the inner sole mating the aperture in the keyway and a pin insertable into the apertured key and keyway beneath the lift tab when the heel is in seated position on the shoe, to hold the heel locked to the shoe whereby when locked there is no 10 apparent difierence from the conventional shoe.
