FR2675349A1 - Variable footwear devices - Google Patents

Abstract

The object of the invention aims to produce devices for obtaining the adjustment of footwear which is appropriate to one's feet. One of the diverse devices describes the structure of sandals with multiple widths offered by a single vamp. Another device describes the bottom-stock structures which can be extended in terms of width.

Description

The present patent application aims at various devices relating to the variable footwear for the popular economic realization of sandals and shoes.

This shoe is comfortable for the various morphologies of the generality of the feet, by the variability of the widths whereas in the so-called popular productions the width is unique with the length.

By means of a new technique suitable for the double extensibility of the internal and external width of the anterior vamp, inverted, and partially elastic, it increases widths by becoming the first elastic mounting in width, where the structure is welded of the anterior sole similarly in width, secured, by an impermeable elasticity welded thereto.

This sole assembly, preferably made of leather, is shaped extensively in width by sliced cells in the shape of diamonds, or the like, except in the periphery of the sole assembly.

This technique for a wide variety of shoe models allows for a length up to three widths, including the rear heel stabilizer correcting the camber and the variable anterior and posterior base parallel to the ground, stabilizes the footwear, whose reference my patent of April 22, 1985 no 8506029.

Regarding shoes of classic manufacturing and classic lines, men, women, children, the elasticity of the uppers is combined with the usual mounting on a first sole, the front part of which is cut by a large alveolus, where it is inlaid by cross stitching. a strong waterproof elastic whose sole is identically extensible across its width, sliced and shaped from cited or other cells.

By this technique, the user is comfortable wearing: comfortably and healthily.

It is valid for 80% of the feet subjected to pernicious discomforts caused by the restrictive industrial and commercial standards present, known as of large distribution, but not in conformity with their reason for being.

FIG. 1 represents the structure of the elements making up the anterior vamp 1, the central part of which is cut off by a cell 2 in which the corresponding part 4 is encrusted by cross-stitching 3, elastic stretchy across the width of the foot
FIG. 2 shows the sole assembly for wear on the ground, the cutouts of which are cut into diamond shapes, for example, extendable 5/6 in width. The internal face of this sole assembly is lined with an elastic fabric or elastic skin reinforced by an extensible waterproof rubber sheet 7, welded back from the external part of the sole assembly and all welded on the cut edge of the leather sole assembly allowing the extensibility. overall width of the sole assembly 8.

Figure 3 shows the recess of the camber 9 in the heel 10 equipped with a ring 11 stabilizing the tightening of the posterior strap on the neck of the foot and ankle.

Figure 4 represents some profiles of the various possibilities of models by this technique 12/13/14/15/16.

 FIG. 5 represents a classic men's shoe of line 17 whose outer vamp is elastic.

FIG. 6 represents the mounting on the first mounting 18, the internal periphery 19 of the front part of which is sliced by a cell 20 in which is encrusted by cross-stitching, the corresponding elastic part 21 extendable across the width of the seat.

The wear sole on the ground 22, sliced and shaped 23 extensible by strong elastic fabric 24 reinforced by a sheet of waterproof houc rubber 25 elastic in width of the foot and welded on the shaped parts and of the sole of the sole in adequate soft tanned leather 26. This sowing will be welded to the assembled upper, carded and ready for welding.

FIG. 7 represents a metal device 26 provided with a double inverted screw thread 27 regulators 28/29 of the lengths for the manufacturing in two parts anterior and posterior.

Claims (2)

1 / Autonomous and interchangeable device with a structure according to the morphological variability of the width of the legs, characterized in that the anterior element is a trench 1 trench of a cell 2 receiving the complementary elasticized element 3 extendable for additional widths 4. 2 / Device according to claim 1 characterized in that 11 complementary base element is the outsole on the ground trench of cells of expandable shapes in width 5, 6 for example which receives on its internal face the waterproof expandable elements 7 covering l internal trenching of the sole assembly 8 on which they are welded.
