INTERCHANGEABLE SOLE AND UPPER FOR SHOES Filed Sept. 10, 1964 2 Sheets-Sheet 2 INVENTORS RAMONA D. LOCKARD HENRY SWATT ATTORNEY United States Patent 3,204,346 INTERCHANGEABLE SULE AND UPPER FOR SHOES Ramona D. Lockard, 7331 W. Plantation Blvd, Miraxnar, West Hollywood, Fla., and Henry Swatt, 1930 NE.

197th Terrace, North Miami Beach, Fla.

Filed Sept. 10, 1964, Ser. No. 395,387 7 Claims. (Cl. 36-25) This invention relates generally to improved and novel construction for shoes or other footwear and more specifically provides a shoe construction having interchangeable elements thereon :so that such elements may be changed as desired for adapting the shoes for various occasions having various decorative qualities.

In shoe construction, and especially that utilized by women, it is necessary that a relatively large number of pairs of shoes be retained so that the shoes will be compatible to the particular clothes being worn. Normally a relatively large number of pairs of shoes presents a storage and cost problem and it usually results in the person buying pairs of shoes that are compatible to a particular wardrobe and it is the primary object of this invention to provide an improved shoe construction wherein the uppers of the shoe may be removably interchanged With the other uppers, thereby permitting a single basic frame or sole to be utilized with a plurality of various colored uppers in mens, womens and childrens footwear in all categories where the construction may be applied permitting a single basic sole to be applicable to a plurality of uppers and greatly reducing the cost of the footwear, since the user may purchase various uppers at a relatively low price for detachable engagement with the sole.

A further object of the invention resides in the combination of a sole, midsole and a sock lining and with the sole being provided with trackways and with the midsole being slotted in accordance with the trackways and also the sock lining being slotted to conform to the trackways with the upper edges of the trackways and being flush with the sock lining and with the upper end of the shoe along its marginal edges being provided with slide devices that are engageable with the trackways to slide along the trackways and to thus anchor the upper against accidental displacement.

Novel features of construction and operation of the device will be more clearly apparent during the course of the following description, reference being had to the accompanying drawings wherein has been illustrated the preferred form of the device and wherein like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

FIGURE 1 is an exploded perspective view of the complete elements forming the assembly of the shoes,

FIGURE 2 is a longitudinal section through one trackway and associated elements for retaining the upper in assembled relation to the sole,

FIGURE 3 is a transverse section taken substantially on line 33 of FIGURE 2,

FIGURE 4 is an exploded perspective view of a modified form of the invention,

FIGURE 5 is a horizontal section taken substantially on line 5-5 of FIGURE 4,

FIGURE 6 is a fragmentary transverse section taken substantially on line 6-6 of FIGURE 5,

FIGURE 7 is a transverse section taken substantially on line 77 of FIGURE 5,

FIGURE 8 is a fragmentary longitudinal section on 8-8 of FIGURE 4 illustrating a bevel for the trackway,

FIGURE 9 is a fragmentary transverse section illustrating a further modified form of the invention, and

3,Zil4,346 Patented Sept. 7, 1965 FIGURE 10 is a fragmentary side elevation of the modified form of the invention illustrated in FIGURE 9.

Referring specifically to the drawings and particularly to FIGURES 1-3, there has been illustrated a sole 5, formed of leather or other desirable material, and 6 illustrates a conventional midsole. Overlying the midsole, is a relatively thin sock lining 7.

Fixed to the sole 5 and conforming to the curvature thereof is a pair of tracks 8, formed of any desirable material such as plastic or other yieldable material. The tracks 8, see FIGURE 3 are rectangular in cross section, having a bottom wall 9 that is cemented or otherwise connected to the sole 5 and with the trackways having side walls 10 and an upper Wall 11 that is provided with a pair of spaced apart flanges 12, presenting an upwardly opening slot 13. The track 8 is of a vertical thickness, corresponding to the midsole 6 and with the flanges 12, projecting upwardly through arcuate slots 14 formed in the sock lining 7. The midsole 6 is also slotted at 15, corresponding to the height of the tracks 8. The slots 14 of the sock lining 7 are enlarged at 16, to provide an insert opening for the slides 17 of the upper 18. Each of the slides 17 are provided with intermediate ribs 19 to which the marginal edges of the upper 18 are stitched or cemented. The slides 17 at their forward ends are provided with buttons or knobs 20 that engage in recesses formed in the forward ends of the slots 15 and whereby to yieldably hold the upper 18 in assembled relation to the trackways.

In the use of this form of the invention, the sole 5 is first provided with the tracks 8 either cemented thereto or otherwise attached and the midsole 6 is then engaged over the trackway, as shown in FIGURE 3 and then the sock lining 7 i disposed over the midsole 6 to be aligned with the slots 13 of the tracks 8. The several elements 5, 6 and 7 are then preferably cemented together, providing a unitary sole construction having the exposed guide slots 14 in the sock lining. When engaging the uppers 18 with respect to the tracks 8, the slides 17 :are first engaged through the trackways to a point where the knobs 20 engage the recesses in the midsole 6. The knobs being yieldable, are snapped into engagement with the recesses and retard the movement of the upper 18 in a rearward direction. The uppers 18 maybe formed of any desirable flexible material having slides 17 stitched to their marginal edge thereof and thus, uppers of varying designs and colors may be inserted into the trackways, forming .a novel type of shoe construction that permits the interengagement of uppers corresponding to the particular wardrobe of the user. Heels, such as that illustrated in dotted lines in FIG- URES 1 and 2 may be employed and form no part of the present invention.

Referring now to FIGURES 4-8, there has been illustrated a similar construction and wherein separate trackways 8 are disposed in spaced apart relation with respect to the sole 5, the midsole 6 and the sock lining 7. In this instance, the spaced apart tracks 8 are shorter than the tracks previously described and the sock lining 7 is also slotted as indicated at 22 to overlie the tracks 21 after the sole and midsole have been assembled, and the flanges 12 project through the slots 22 to be flush with the sock lining. The slots 22 are also provided with the enlarged openings 23 for the insertion of slides 24 of the strap type upper 25. The slides 24 are provided with the ribs 26 to which the ends of the straps 25 are either cemented or stitched.

In this form of the invention, the shortened trackways 8 [are fixed to the sole 5 and the midsole 6, being slotted at 21 is engaged over the trackways flush with the upper wall 11 of the trackways and with the flanges 12 extending through the slots 22 of the sock lining, forming spaced apart tracks into which the slides 24 are engaged and the slides 24 are also provided with the knobs 20 that have yieldable fitment int-o recesses formed at the forward ends of the tracks, the tracks 'at. their rear extremities may be beveled as indicated :at 27 in FIG- URE 8 to facilitate the entry of the slides 24 and the same may apply to the first form of the invention with respect to the tracks 8 since the upper and their slides are relatively flexible and facilitates the guidance of the slides into the tracks.

In FIGURES 9 and 10, there has been illustrated a further modified application of the invention wherein tracks 8a .are disposed upon the soles and the tracks 8a are of a height corresponding to the midsole 6. Here, the tracks 8a are vertically arrange-d and the slide openings are disposed upon the marginal edge of the shoe, shown at 13a in FIGURE 10. The trackways 8a are also provided with the enlarged entrance opening 16a to facilitate the entrance of the slide 17a and as shown in FIGURE 9, the rib 19 of the slides carry the uppers 18. IT his form of the invention may be desirable where the upper is disposed with respect to the trackways out- Wa-rdly of the marginal edge of the midsole 6, while in the first form of the invention, the uppers terminate on the ribs 19 inwardly of the marginal edge of the sock lining.

It will be apparent from the foregoing that novel means has been provided for detachably engaging the uppers to the sole construction of a shoe and for permitting interchanging of the uppers so that a single main sole, mid s-ole and sock lining may be employed with various uppers for completely changing the appearance and construction of the shoe, thereby permitting a single shoe with a plurality of uppers to be utilized in conjunction with a plurality of dresses or outfits of wearing apparel, thereby eliminating the necessity of having a relatively large number of pairs of shoes available for use.

The device is simple in construction, cheap to manufacture, is strong, durable and most effective for the purposes indicated.

It is to be understod that the invention is not limited to the precise construction shown, but that changes :are contemplated as readily fall within the spirit of the invention as shall be determined by the scope of the subjoined claims.
