Definitions
- the invention relates to an article of footwear, such as a shoe or any equivalent.
- the footwear can be used in areas such as walking, running on flat terrain or in the mountains, wheeling, ball sports, cross-country skiing, snow surfing, snowshoeing, snowshoeing and snowboarding. bike or other.
- the article of footwear must fulfill various functions, sometimes antithetical, such as ensuring a maintenance and / or a sufficient tightening of the foot while offering a satisfactory comfort.
- the article of footwear must also have a certain flexibility, a quality which consists in a good aptitude for marrying certain deformations of the foot. In other words, the article of footwear must adapt to the foot by leaving it the latitude necessary for the walk or the sport in question.
- the upper generally comprises a number of parts, such as a side section, a medial area, a vamp, a tongue, a heel, a rear buttress, a front protection cap, a tightening device including passers-by and a lace, a lining. internal, or even other parts. In addition, some of these may include several parts.
- the main problem in a shoe is to assemble and put into a three-dimensional shape pieces cut and assembled flat.
- the rod is associated, in known manner, with a mounting flange, to delimit a footwear element. According to a first method, the rod is glued to the mounting flange by a layer of glue.
- the mounting flange also called the first mounting
- the gluing is done by pulling the rod to press it on the first of assembly, knowing that a form is inserted in the stem. This is called traditional form fitting. This technique allows to exert sufficient pressure during the heating of the glue, to obtain the footwear element.
- a second method also known, is to achieve the footwear element by joining the rod to the first mounting by means of a seam. This is called Strobel editing.
- the first assembly is here a flexible sole, which can be sewn, called Strobel sole. For each of the first and second methods, the first assembly is part of the assembly.
- the latter further comprises external parts, such as one or more damping layers, as well as a wear layer, provided for contacting the ground, which are generally fixed by gluing on the first mounting and on the rod mounted on form .
- the sole comprises one or more inner layers, disposed in the footwear element, to perform protective functions in terms of hygiene, damping, arch support, or other. In the end, the combination of the footwear element with the other components of the sole formation form the shoe.
- a shoe according to the prior art has certain drawbacks.
- the shoe uses a high number of coins, generally between forty and sixty. Because the number of pieces constituting the shoe is high, the number of manufacturing operations and the time required to conduct them are high. It usually takes forty minutes to an hour and thirty minutes to make a shoe. It can be said that shoes made according to conventional techniques are complicated by both the number of their components and the number of manufacturing operations.
- the Applicant has proposed another approach to manufacturing an article of footwear.
- an article of footwear comprises one or two envelopes, each envelope extending in length from a rear end to a front end, in width between a lateral edge and a medial edge, and in height from a bottom to an upper end, each envelope comprising son mechanically connected to each other.
- the envelopes are shaped in volume, that is to say in three dimensions, being placed on a shape to present a geometry very similar to that of a foot, and thus they marry the foot very homogeneously. This means that the foot is in contact with, or at least very close to, the envelopes. This results in a uniform support of the foot with very little unwanted movement between the latter and the envelopes, or with no movement.
- An advantage that arises is an increased comfort of the article of footwear, compared to a shoe according to the traditional prior art.
- each envelope has continuity of structure, in the sense that its internal surface and / or its outer surface are, if not totally regular, at least substantially regular. This results advantageously that the user is less embarrassed, if at all.
- the invention generally seeks to further improve an article of footwear. More specifically, the invention wants, for example, to improve the transmission of driving pulses, the restitution of the reactions of the ground or of a machine, or the perception of sensory information.
- the invention seeks to optimize the efficiency of use, and reduce the fatigue of a user.
- the invention still seeks to meet the specific needs of a user, retaining its basic qualities such as comfort and support of the foot. In the case of search support or transmission of intense information, for example during sports use, it is a real challenge. Indeed, the comfort and the optimization in the transmission of the efforts are concepts a priori antinomic.
- the invention provides an article of footwear which comprises a first envelope, the first envelope extending in length from a rear end to a front end, in width between a lateral edge and a medial edge, and in height from a bottom up to at an upper end, the first envelope comprising son mechanically connected to each other, the first envelope delimiting a reception volume of a foot, the footwear comprising a second envelope, the second envelope extending in length from a rear end to a front end, in width between a lateral edge and a medial edge, and in height from a bottom to an upper end, the second casing comprising wires mechanically connected to each other, the second envelope defining a reception volume of one foot, the first envelope and the second envelope being arranged opposite one of the other.
- the article of footwear according to the invention is characterized in that at least at least one subdivision comprises a reversibly resiliently deformable intermediate piece, the insert being disposed between the first envelope and the second envelope.
- the insert may be a tongue.
- the insert may be a portion of sole.
- the insert allows a relative displacement of the portions of the envelopes against which it is located. Because it is able to crush elastically in a reversible manner, the insert allows the relevant portions of the envelopes to approach one another, for example during special solicitations, to then find their distance from each other. natural gauge. This distance corresponds to the thickness of the insert.
- the spacer By crashing, the spacer spreads a portion of the compression forces in directions other than a direction perpendicular to it and thus dampens these forces.
- the intermediate part enlarges the transmission surface of the efforts related to the use of the article, the different pulses, or sensory information.
- the transmission of forces, pulses or information is not impaired.
- the invention thus succeeds in ensuring that the article is both comfortable and precise in its uses. This improves the user's performance, and reduces his fatigue.
- the invention improves the structure and the method of manufacture of a footwear item.

- the first embodiment that will be described after relates for example to an article of footwear for walking or for running on horizontal terrain or in the mountains. However, the first embodiment applies to other fields such as those mentioned before.
- a footwear 1 is provided to accommodate the foot of the user. It is appropriate for the rest of the description to consider that the article of footwear 1 is a shoe even if, we will see soon in detail, its structure is totally unusual.
- the boot 1 extends in length, in a longitudinal direction L, between a rear end or heel 4 and a front end or tip 5, and in width, in a transverse direction W, between a lateral edge 6 and an edge medial 7.
- the shoe 1 comprises a lower portion 10, provided to surround the foot, excluding any high portion.
- a shoe comprising both a low portion and a high portion, the latter being provided to surround the ankle and possibly the lower leg.
- the shoe 1 extends in height from a bottom 12 to an upper end 13, that is to say up to the free end of the lower portion 10 or the shoe 1.
- the bottom is a subdivision of the shoe on which the foot is supported.
- the shoe 1 is structured to allow a smooth running of the foot during walking, transmissions of sensory information, and impulses for support or receptions. This is why the shoe 1, or footwear, is relatively flexible.
- the boot 1 comprises a first casing 21 which extends in length, in the longitudinal direction L, from a rear end 24 to a front end 25, in width, in the transverse direction W, between a lateral edge 26 and a medial edge 27, and in height from a bottom 28 to an upper end 29.
- This allows the first envelope to surround and maintain the foot of the user.
- the first envelope includes son connected to each other mechanically, as will be explained later. Also, for the first envelope, at least a portion of the son comprises at least one hot-melt filament, as will also be explained later.
- the son of the first envelope which comprise at least one hot-melt filament are distributed over the entirety of the first envelope 21, and the fusion of the yarns contributes, to a greater extent or less, depending on their quantity, their concentration, the strength and / or the bonding and / or the abrasion resistance of the first envelope.
- the fusion confers on the first envelope 21 the ability to retain its shape by itself.
- the first envelope 21 is a one-piece piece and, on the other hand, that it can form a self-supporting part, giving the shape of the shoe, to a greater or lesser extent, depending on the quantity / concentration of the threads.
- the first envelope 21 gives or contributes to giving shape to the shoe 1.
- the rear end 24, the front end 25, the lateral edge 26, the medial edge 27, the bottom 28 and the upper end 29 of the first envelope delimit respectively the rear end 4, the front end 5, the lateral edge 6, the medial edge 7, the bottom 12 and the upper end 13 of the footwear or shoe 1
- the minimalist structure adopted for the envelope 21 is a guarantee of simplicity, lightness, and many other advantages, as we will see later.
- the boot 1 also comprises a second casing 31 which extends in length, in the longitudinal direction L, from a rear end 34 to a front end 35, in width, in the transverse direction W, between a lateral edge 36 and a medial edge 37, and in height from a bottom 38 to an upper end 39.
- the second envelope 31 covers the foot too, at the Like the first 21.
- the second envelope 31 is disposed outside the first envelope 21 and, therefore, covers the foot indirectly.
- the shape of the shoe 1 is given both by the first envelope 21 and the second envelope 31.
- the first envelope 21 and the second envelope 31 are arranged opposite one another.
- the second envelope 31 comprises son connected to each other mechanically.
- at least a portion of the son comprises at least one hot melt filament, as will be explained later.
- the yarns which comprise at least one hot-melt filament are distributed over the entirety of the second envelope 31, and the fusion of the yarns contributes, to a greater or lesser extent, depending on their quantity and concentration, to the holding and / or the bonding and / or abrasion resistance of the second envelope.
- the fusion confers on the second envelope 31 the ability to retain its shape by itself.
- the second envelope 31 is a one-piece piece and, on the other hand, that it can form a self-supporting part, giving its shape to the shoe, to a greater or lesser extent, as a function of the quantity / concentration of the threads.
- the second envelope 31 gives or contributes to give shape to the shoe 1.
- the rear end 34, the front end 35, the lateral edge 36, the medial edge 37, the bottom 38 and the upper end 39 of the second envelope 31 also delimit respectively the rear end 4, the front end 5, the lateral edge 6, the medial edge 7, the bottom 12 and the upper end 13 of the footwear or shoe 1.
- the minimalist structure adopted for the envelope 31 is a guarantee of simplicity, lightness, and many other advantages, as we will see later.
- each envelope 21, 31 is done by manufacturing a sleeve 41, that is to say in fact a flexible tube made of wires linked to each other mechanically.
- the sleeve 41 is a blank for the realization of the article 1.
- the sleeve 41 makes it possible to make both the first envelope 21 and the second envelope 31.
- the sleeve 41 extends in length from a first end 42 to a second end 43.
- the first end 42 is closed by any technique known to those skilled in the art, such as a stitch after folding, the addition of a ferrule made of wires connected to each other mechanically, or any equivalent.
- the second end 43 for its part, is simply an opening.
- the sleeve 41 makes it possible to manufacture the envelopes 21, 31 in one piece.
- the first envelope 21 and the second envelope 31 extend one another. This simplifies manufacturing by reducing the number of parts and the time required for implementation.
- the threads are mechanically linked to one another and are examples associated with each other by any suitable textile technique, such as knitting, weaving, braiding, or other.
- any suitable textile technique such as knitting, weaving, braiding, or other.
- knitting it is possible to use a circular loom single needle or double needle, a cylinder loom, or a straight loom.
- Two knitting zones can be joined to each other by Intarsia technique or by embroidery.
- Various decorative patterns can be obtained directly during knitting, by the Intarsia method, embroidery, Jacquard technique, or other.
- Figure 5 symbolizes a traditional weave with first son 44 oriented in a first direction, second son 45 oriented in a second direction, the first 44 and second 45 son crossing to form a flexible mesh.
- the sleeve 41 is for example manufactured with a straight loom, which allows to vary the sections, that is to say in fact the diameter of the sleeve, to make shape variations for the heel, to make openings for the passage of laces, to vary the density of the wall of the sleeve, or in particular to vary the tightening of the loops.
- the rectilinear craft offers a wide range of adjustment possibilities, and it is suitable for making sleeves of all sizes, either in diameter or in length.
- the straight line is more practical than the circular loom. Indeed, the latter works on a reduced range at the diameter of the sleeve.
- the yarn may be a monofilament, obtained for example by extrusion of a hot melt synthetic material, such as a polyamide, a polyurethane, a polyethylene, or any equivalent material or the like.
- a hot melt synthetic material such as a polyamide, a polyurethane, a polyethylene, or any equivalent material or the like.
- the production of a filament is continuous, comparable to the silk filament produced by a spider.
- the filament may be single-component, or mono-material, in the sense that its cross-section is regular.
- the filament can also be multi-component, for example two-component.
- a cross-section of a filament shows a heart made of a first material, and a peripheral envelope which surrounds the core, envelope made of a second material.
- Each material can be hot melt, or only one can be. If both materials are, their melting temperatures are different.
- the wire can be multi-filament. It is in this case obtained by association of several filaments. Such an association is represented by the diagram of FIG. 7.
- all the filaments 49 are of the same nature, in the sense that each of them has the same melting point. But we can provide combinations of filaments of different kinds, some of which may be fusible and others not, or with different melting points.
- the filaments are associated with each other by any known technique.
- the yarn can be made in the form of a net of fibers.
- a fiber is a filament of limited length.
- the fibers are associated by close contact to form the net, by any known technique and in particular by torsion.
- the maintenance of the fibers to each other is traditionally made by friction, especially with natural fibers such as cotton.
- the maintenance of the fibers to each other is done either by friction, or by combination of friction and melt adhesion, or still completely by adhesion, because the invention uses hot melt materials.
- the footwear item 1, or shoe includes a reinforcement 51. It will be seen better after this reinforcement is associated with the envelopes 21, 31 by interlocking at the time of manufacture of the shoe 1, to give it- here are specific skills.
- the reinforcement 51 is a piece which extends in length from a rear end 54 to a front end 55, in width between a lateral edge 56 and a medial edge 57, and in height from a bottom 58 to one end 59.
- the reinforcement 51 has a length and a width similar to the lengths and widths of the envelopes 21, 31. Specifically, the reinforcement 51 extends, in relation to the first envelope 21, in length from the rear end 24 at the front end 25, in width between the lateral edge 26 and the medial edge 27, and in height from the bottom 28 towards the upper end 29. This allows, by definition, to reinforce the first envelope 21, and therefore the article footwear 1, especially at the bottom 12 and the periphery of the bottom.
- the reinforcement 51 carries a clamping device 61.
- This comprises for example loops 62, located at the upper end 59, and a lace 63 and a locking device 64, known from the skilled person. It is therefore possible to tighten or loosen the reinforcement 51 and, in doing so, to tighten or loosen the shoe 1, as it will appear better after.
- passing 62 is meant any device used to pass, slide a lace.
- the locking device is optional and can be replaced by a simple lace knot.
- the reinforcement 51 comprises a bottom 58, at least one side branch 65 extending from the bottom towards a free end 66 in a direction away from the bottom, free end 66 having a loop 62, at least one medial branch 67 extending from the bottom towards a free end 68 in a direction away from the bottom, the free end 68 having a loop 62, and at least one lace 63 passing through passers-by.
- the reinforcement 51 comprises four lateral branches 65, as well as four medial branches 67. But these numbers can respectively be different. It also appears that each branch 65, 67 has a loop, which is made by any technique known to a person skilled in the art. Finally, the reinforcement associated with the clamping device allows a uniform clamping of the envelopes 21, 31, and therefore the foot consequently.
- the lateral branch 65 and the medial branch 67 are arranged in part at least between the first envelope 21 and the second casing 31, and the loops 62 are disposed outside the first casing 21 and also outside the second casing 31.
- the footwear comprises a spacer member 71 resiliently deformable reversibly, the insert 71 is disposed between the first envelope 21 and the second envelope 31.
- the insert is compressed proportionally to efforts related to the use of the article, to resume its initial thickness when the efforts disappear.
- the spacer absorbs some of the compression energy applied to it, and also diffuses some of this energy in directions other than a direction that is perpendicular. This reduces the specific pressure at the level of the envelopes, for a better comfort.
- the insert 71 has an elongated shape and is intended to extend under the clamping / lacing system so as to protect the user's instep and so it defines a tongue.
- the tongue 71 is located at the upper ends 29, 39 of the first 21 and second 31 envelopes, the tongue 71 extending in length from a rear end 74 to a front end 75, in width between a lateral edge 76 and a medial edge 77, and in thickness between a bottom 78 and a top 79. This is to improve the comfort of the footwear at the upper ends of the envelopes. For the user, it is the top of the foot that is better protected, ie the instep and / or the bending crease.
- the rear end 74 of the tongue is wider, which gives more or less the shape of a T.
- the tongue could also have a homogeneous rectangular shape, the essential being that it extends under the lacing and reconcile the functional aspects and lightness, as well as aesthetic depending on the case.
- the tongue could also have other functions than those described and for example aesthetic only. It can also be provided that the tongue extends only under the lacing portion (off), which always protects the instep.
- the rear end 74 of the tongue 71 is, in the example, secured to the first envelope 21 and / or the second envelope 31, a substantial part of the remainder of the tongue being disconnected from the first casing 21 and / u of the second casing 31.
- the securing of the rear end is made by any appropriate means such as a bonding, or any equivalent or complementary technique. The fastening can be carried out in any other way.
- the rear end 74 of the tongue is secured to the two envelopes 21, 31, which also allows to have an excellent finish at the aesthetic level.
- the tongue 71 comprises a layer of elastically deformable synthetic material.
- This layer may be an ethylene vinyl acetate (EVA) foam, a polyurethane foam, a polyethylene foam, or any other material capable of performing the same function.
- EVA ethylene vinyl acetate
- the tongue may comprise several parts, for example several layers, arranged relative to each other appropriately, and also include natural materials such as cork or any equivalent.
- At least one of the first 21 and second 31 envelopes has folds 81, 82, 83, 84 at the lateral edge 76 and / or at the medial edge 77 of the tongue 71. More precisely here, the first envelope 21 has a lateral fold 81 and a medial fold 82, and the second envelope 31 also has a lateral fold 83 and a medial fold 84. These folds allow variations in the volume of the shoe of the article, because they make the geometries of envelopes 21, 31 variables. In other words, the folds facilitate donning and heaving, but disappear once the foot in the shoe.
- the sleeve 41 is threaded onto a part 86, called shape, which is in the image of the foot of the user.
- the sleeve is applied to the shape 86 in the manner of a sock on a foot.
- the sleeve 41 is shaped by the shape 86 thanks to its elasticity, which is due to its textile constitution.
- the reinforcement 51 is fitted on the subdivision of the sleeve 41 which will become the first envelope 21.
- the subdivision of the sleeve 41 which will become the second envelope 31 is folded over the reinforcement 51, thereby covering the latter and the subdivision attributed to the first envelope.
- the article of footwear 1 or shoe comprises an outer sole 88.
- the latter is intended to bear on the ground and, as such, is structured to withstand wear and tear. friction and also to cushion shocks. It therefore comprises, by way of example, a wear layer 89 and a damping layer 90.
- the bottom 12 has a non-planar geometry, substantially identical to that of the vault mentioned above.
- the shoe 1 according to the invention is indeed able, as we said, to comply with the foot. It is therefore not essential, although it may be useful, to add to the shoe 1 an insole to reproduce the arch, or the other aspects of the underside of the foot.
- the shoe according to the invention is suitable for example very well for a runner.
- FIG. 2 also shows that the reinforcement 51 is located almost entirely between the first envelope 21 and the second envelope 31.
- first envelope 21 and the second envelope 31 are continuous in a cross section. These envelopes therefore extend continuously at their respective upper ends 29, 39, even if they have folds, and thus at the upper end 13 of the shoe. The wrapping of the foot is therefore total and permanent.
- the boundary between the first envelope 21 and the second envelope 31 is a fold 93 which delimits a boot opening 94.
- periphery of the boot opening 94 is therefore delimited simply by folding the two envelopes 21, 31 one on the other. This means that this periphery has no seam or insert, as in the prior art, and that therefore the shoe 1 is not a source of discomfort for the user including the opening 94 .
- FIG. 11 there is an article of footwear or shoe 1, with its lateral 6 and medial edges 7, or its bottom 12 and its upper end 13. There is also the first envelope 21, the second envelope 31, the reinforcement 51, the loops 62, or the tongue 71.
- This insert 101 is a portion of a sole 102, the sole portion being located at the funds 28, 38 of the first 21 and second 31 envelopes, the portion 101 of the sole 102 extending in length from a rear end 104 to a front end 105, in width between a lateral edge 106 and a medial edge 107, and in thickness between a bottom 108 and a top 109.
- the portion 101 allows a relative movement of the portions of the envelopes opposite which it is. In this case, it is the whole or subdivisions of the funds 28, 38 of the envelopes 21, 31.
- the insert allows the portions concerned envelopes to approach each other, for example during special requests, to then find their distance of natural spacing. This distance corresponds to the thickness of the insert. This is to get better damping shocks or pulses in the sole of the foot. An advantage that results for example is a better preservation of the user's joints.
- the intermediate part namely the portion 101 of the sole assembly 102, extends opposite all the funds 28, 38 of the first 21 and second 31 envelopes. This makes it possible to obtain a damping effect at the level of the entirety of the bottom 12 of the article of footwear.
- the insert 101 added as described in connection with the tongue 71, is for example secured to the first casing 21 and / or the second casing 31.
- the joining is done by any appropriate means such as a bonding, or any technique equivalent or complementary. This optimizes the cooperation between them of the funds 28, 38 of the envelopes 21, 31, in the sense of a more precise transmission of the pulses or the sensory information. But it can alternatively be planned to have the insert without interlocking with the funds.
- the insert 101 comprises a layer of elastically deformable synthetic material.
- This layer may be an ethylene vinyl acetate (EVA) foam, a polyurethane foam, a polyethylene foam, or any other material capable of performing the same function.
- EVA ethylene vinyl acetate
- the intermediate part or portion 101 may comprise several parts, for example several layers, arranged relative to each other appropriately, and also include natural materials such as cork or any equivalent.
- the article of footwear 1 comprises a wear layer 111 and at least one intermediate layer 112 located between the wear layer 11 and the bottoms 28, 38 of the envelopes 21, 31, the wear layer. wear 111 and the intermediate layer 1 12 constituting an outer sole. This allows a certain level of damping directly at the level of the wear layer.
- the article in the third form comprises another intermediate piece 121 between the two envelopes 21, 31.
- This intermediate piece 121 is a portion of a soleplate 122, the soleing portion being located at the bottoms 28, 38 of the first 21 and second 31 envelopes, the sole 121 portion 122 extending in length from a rear end 124 to one end before 125, in width between a lateral edge 126 and a medial edge 127, and in thickness between a bottom 128 and a top 129.
- the portion 121 allows a relative movement of the portions of the envelopes opposite which it is. In this case, it is the totality or subdivisions of funds 28, 38 envelopes 21,31. Because it is able to crush elastically in a reversible manner, the insert allows the relevant portions of the envelopes to approach one another, for example during special solicitations, to then find their distance from each other. natural gauge. This distance corresponds to the thickness of the insert. This is to get better damping shocks or pulses in the sole of the foot. An advantage that results for example is a better preservation of the user's joints.
- the insert namely the portion 121 of the sole assembly 122, extends opposite all the funds 28, 38 of the first 21 and second 31 envelopes. This makes it possible to obtain a damping effect at the level of the entirety of the bottom 12 of the article of footwear.
- the intermediate piece 121 is for example secured to the first casing 21 and / or the second casing 3 L
- the fastening is made by any appropriate means such as a bonding, or any equivalent or complementary technique. This optimizes the cooperation between them of the funds 28, 38 of the envelopes 21, 31, in the sense of a more precise transmission of the pulses or the sensory information. But it can alternatively be planned to have the insert without interlocking with the funds.
- the intermediate piece 121 comprises a layer of elastically deformable synthetic material.
- This layer may be an ethylene vinyl acetate (EVA) foam, a polyurethane foam, a polyethylene foam, or any other material capable of performing the same function.
- EVA ethylene vinyl acetate
- the intermediate piece or portion 121 may comprise several parts, for example several layers, arranged relative to each other appropriately, and also include natural materials such as cork or any equivalent.
- the article of footwear 1 comprises a wear layer 131 secured directly to a bottom 38 of an envelope.
- the bottom 38 of the second envelope 31 which defines the outside of the footwear.
- This architecture promotes a more direct transmission of driving impulses and sensory information.
- the cushioning portion 121 of the sole assembly is fully integrated into the upper, which gives the shoe a particular aesthetic appearance, only the outsole being visible.
- the aesthetic effect of a construction of the double-lasting type is thus obtained. much more expensive to implement.
- it may be provided to add one or more intermediate pieces in another part of the article of footwear and, for example forward to form a toe protection toe, backwards to provide support additional heel, or at an edge to protect the ankle.
