Definitions

• the subject of the present invention is a reversible footwear article and the method for preparing this article.
• the invention relates more particularly to infant articles such as slippers.
• Footwear comprising in a known manner a sole with a rod, the two elements being assembled by a technique called "overlocking" but this type of article has no possibility of being reversible by the very structure of the assembly.
• both the upper and the sole are generally made up of a single layer of fabric or leather material, which itself can be reversible as a material, but this does not necessarily make the article reversible.
• the present invention provides a method of manufacturing a reversible footwear item comprising two superposed layers of fabric.
• This article is of a low additional cost price for a very sensitive commercial interest and it provides advantages for the still unknown consumer. We note that it is possible to double the possibilities to wear clothing and shoes or slippers.
• the method of manufacturing an article of footwear, according to the invention is characterized by the following stages:
• the present method of manufacturing an article of footwear is characterized by the following steps: - cutting of the pieces forming the upper according to the shape of the footwear to be obtained, this in duplicate in a first and a second material,
• the soleplate is made from ⁇ ⁇ - .. x blanks respectively in a first and a second fabric and having a planking, and the connection is made by seaming between the two plankings of the sole and of the upper.
• At least one chute is produced by an additional seam, so as to be able to introduce a lace.
• the rod comprises a slap and a rear quarter, themselves comprising two parts and the parts are assembled before the planking of the rod is produced.
• the parts of the slap comprise a tongue which has been cut out with said slap and these tongues are assembled before the planking of the rod is produced.
• the subject of the invention is also a method of manufacturing a sole by injection for such an article of footwear, which is characterized by the succession of the following steps:
• FIG. 1A a view of an article of footwear of the infant slipper type, showing on the outside a first fabric
• - Figure 1 B a view of the same footwear as that of Figure 1 A, but after it has been turned over, thus showing a second fabric on the outside
• FIG. 2A a view of an insulated sole intended to be mounted as in FIGS. 1 A and 1 B, showing the first face in the first fabric
• FIG. 2B a view of the same sole as that of FIG. 2A but seen on the other face and produced in the second fabric
• FIG. 3A a sectional view along line 3A-3A of FIG. 1A, - FIG. 3B, a sectional view along line 3B-3B of FIG. 1B,
• FIG. 5 a view of the footwear before final assembly like that shown in FIG. 1 A or 1 B,
• FIG. 6 a sectional view of the footwear according to the invention with means for producing an inner and outer sole simultaneously, by injection, and
• FIG. 1 A there is shown an infant bootie which includes a slap 10, a rear quarter 1 2, a sole 1 4 and a tongue 1 6 which is cut with the slap.
• chute 1 8 provided for slidingly receiving a lace 20.
• FIG. 1A the outer surface 21 produced in a first fabric 22 has been left blank, and in FIG. 1B, the outer surface produced in a second fabric 24 has been shown with hatching.
• FIG. 4 the various parts necessary for the production of the liner of FIGS. 1 A and 1 B are visible in exploded form.
• the rear quarter 1 2 comprises two pieces 26 and 28 made one from the first fabric 22 and the other from the second fabric 24.
• the two pieces are assembled by an attached stitching 30 on the reverse side, the place only being visible in this figure 4.
• This stitching defines, as will be explained later, the upper edge of the liner 32, also referenced in Figures 1 A and 1 B.
• edges 34 and 36 of these two pieces receive a plank 38 and 40, these two planks running over the entire length of the edges of the first piece 26 and over part of the edges of the second piece 28, the edges being considered perpendicular to the stitched joint 30.
• the slab 1 0 which comprises two parts 46 and 48 produced respectively in the first fabric 22 and in the second fabric 24.
• each of these parts 46 and 48 of the slap have a free edge 54 and 56 and lateral edges 58 and 60 .
• the lateral edges 58 of the piece 46 of the slap 1 0 are sewn astride the edges 34 and 36 of the piece 26 of the rear quarter 1 2, these edges having received a planking 38 and 40 and the assembly being produced in the first fabric 22.
• the side edges 60 of the piece 48 of the slap 1 0 are sewn joined with the edges 34 and 36, of the piece 28 of the hindquarters 1 2, these edges having received a planking 38 and 40 and the the assembly being produced in the second fabric 24.
• the two parts 50 and 52 should be joined to definitively form the tongue 1 6.
• the sole 14 also comprises two pieces 62 and 64 cut respectively from the first fabric 22 and from the second fabric 24, then assembled and bordered by a single planking 66.
• the finishing consists in stitching the two pieces 26 and 28 of the rear quarter at a given distance from the upper edge 32, thus producing a chute 1 8 into which a lace 20 is threaded.
• the reversibility is thus total.
• This elastic is preferably placed between the two fabrics 22 and 24, which makes it perfectly invisible, even after reversibility. With regard to children and adults likely to walk with such footwear, it is necessary to provide a sockliner to remove during the reversibility operation and to put back before a new use.
• the sole is made of a wear-resistant material, such as leather, rubber or an elastomer.
• a wear-resistant material such as leather, rubber or an elastomer.
• the materials used have been cited as being fabrics, but they can be chosen from synthetic materials or natural materials such as leather or combinations thereof.
• each part can itself be made up of different materials and be broken down into several parts without thereby escaping the characteristics of the present invention.
• the sole 14 is a sole made of a sheet of material capable of supporting a plastic injection molding. It is provided with holes 80, called communication and balancing holes. This sole 1 4 is sewn at 82 over its entire periphery to the various parts of the liner such as the slap 1 0 and the rear quarter 1 2.
• Sewing has a double role, the first being to secure the sole to the upper of the liner, as well as to position the sole relative to the upper for the injection operation while retaining it in place during the phase injection proper.
• a type of seam is used which limits the overlapping of thicknesses so that the edge of the sole is harmonious and does not cause any discomfort to the wearer.
• the process for molding a reversible sole suitable for the reversible slippers according to the invention comprises the following steps:
• the counter-form 86 does not require any detail since it is within the reach of those skilled in the art.
• the form 84 includes two front parts 84A and rear 84B.
• the front part 84A comprises a support 90 on which is removably attached a front part 92A of a block 92 with the profile and the surface condition retained for the sole.
• a movable core 94 is mounted sliding in translation relative to the support with guide means, not shown but which can take the form of grooves / tongues.
• a spring 96 working under compression, is interposed between the support and this movable core.
• the rear part 84B has a flat surface combined with the planar shape of the rear of the front part so as to produce a joint plane 98.
• This rear part conforms to the profile of the rear of the liner. It comprises a fixed core 100 on which the rear part 92B of the block 92 is removably attached.
• This two-part embodiment facilitates demolding by the relative movement of the front core relative to the rear core.
