Description

COMPENSATION SOLE

The present invention relates to a shoe insole comprising a first face adapted to be in contact with the bottom of a shoe and a second face adapted to be in contact with the foot of the user of the shoe, the sole comprising a part before able to take place in the front part of the shoe and a rear portion adapted to take place in the rear part of the shoe in the vicinity of the heel.

The world of footwear is moving towards ever more customization of products, especially with regard to the insoles that can be added to the interior of the shoe.

In an effort to appear to have a larger size or to increase the comfort of the foot, many people use small devices that are lodged in the shoe under the heel, which is called talonnettes. These devices are either simply placed on the bottom of the shoe or possibly glued.

Unfortunately experience shows that existing devices are difficult to stay in place, take off if they were glued and then tend to migrate to the middle of the shoe, ceasing to play their role and causing discomfort for the user.

Moreover, these devices are often easily detectable or even directly visible when the user removes his shoe. The invention provides a shoe insole for the purpose of correctly maintaining in place, and in time, the heel (s) inserted (s) in the shoe, and in a way that is aesthetic and the least visible possible.

According to the invention, a shoe insole comprising a first face capable of being in contact with the bottom of a shoe and a second face adapted to be in contact with the foot of the user of the shoe, the sole comprising a front portion capable of to take place in the front part of the shoe and a rear portion adapted to take place in the rear part of the shoe in the vicinity of the heel, is characterized in that the rear portion comprises at least two lamellae superimposed one above on the other, a first lamella being disposed in the extension of the front part of the sole and under a second lamella, a housing which can remain between the first and the second lamella.

The face in contact with the shoe may advantageously have a non-slip surface.

The size of the first lamella may be that used for so-called universal soles or be that adapted to each existing size. The sizes of the other lamellae are deduced from that used for the first lamella.

The first lamella may advantageously comprise in its central part, and elsewhere if necessary, a surface creating a thickness intended to improve the comfort associated with walking: damping and shock absorption, and also contain any other modern technology (step measurements, monitoring vital parameters such as body temperature, heart rate ...).

The nature of the materials used for the sole is potentially unlimited but can, because of its volume, be adapted to receive smart textiles using digital and nanotechnology and / or cosmeto-textiles and / or bio-active textiles and any other textile or material that is part of the family of wearable technologies ...

The soleplate may comprise three lamellae, a first housing that can remain between the first and the second lamella and a second housing that can remain between the second and the third lamella.

This principle can of course extend to a larger number of lamellae.

Advantageously at least one heel is inserted into the housing between the first and the second lamella. The length of the second lamella may usefully be determined according to the usual dimensions of heelettes available on the market which will be in this way well maintained between the first and the second lamella.

If more than two slats are used, heelpieces can be placed in the spaces thus created, by superimposing them or not on each other as it is recommended in the case where there would be only two slats.

The sole can be made in one piece or made in two parts, the second blade being sewn and / or glued on the rest of the sole. Any other technique better adapted to the nature of the separate parts to be maintained in a durable and reliable way is potentially valid. It is up to the skilled person in charge of making this compensated sole to choose the most suitable technique.

In the case of several strips, the same recommendations concerning the design of the assembly, a single piece or several elements sewn or glued or any other means of assembly, is to be taken into consideration.

Advantageously, the first blade is extended by a tongue. The primary purpose of this tongue is to facilitate the extraction of the sole of the shoe in which it has been inserted. Indeed, in the case of some shoes such as boots for example, this extraction would probably be difficult without an extraction aid such as the tab.

The shape of the shoe can condition the size of the tongue. We recommend that this tongue can, in its vertical part, be cut by the user so that it does not protrude from the shoe.

The tongue also has at least one other advantage. Indeed the inner part of the tongue will be in contact with the foot inserted into the shoe and in particular the rear part of the heel. Particular care must therefore be taken in the production of the tongue, in particular with regard to its internal surface, so as to improve the user's comfort, especially in the case where the position of the heel in the shoe is not the one that had been planned by the designers of the shoe.

Indeed in the case of the use of heelettes, the foot of the user will be in a higher position relative to the sole of the shoe and because of this, the heel will be above the position which had been planned for him by the designers of the shoe, which will often generate discomfort for the user. That is why it is advised to the user, for the comfort, the invisibility of the sole and to keep a natural gait, to rise up to a maximum of 3.5 to 4 centimeters, so as to preserve the invisibility of the sole in a classic shoe.

The tongue and the first lamella can be made in one piece. In such a case the entire sole may be monobloc or the second lamella may be reported on the group comprising the first lamella and the tongue by means of techniques known to those skilled in the art such as gluing and / or the realization seams and / or any other joining technique best suited to the materials used for the design of these different parts.

The tongue may also include a base which is inserted under the rear part of the first blade.

The tongue can be separated from the first lamella. Especially in the case where the tongue is associated with a base, it is possible to separate the tongue and base unit from the rest of the sole. Indeed the shape and in particular the length of the tongue are parameters that are very dependent on the shoe where is inserted the sole. It is understandable that boots will allow the use of a long and enveloping tongue without its existence being suspected by an outside observer. In contrast, a moccasin type shoe will only allow the use of a very short tongue. The user has the possibility of adding a classic sole to his size over the sole according to the invention so as to keep the device invisible.

Therefore if the tongue and the base are separated from the rest of the sole, it becomes possible to use several tabs of different shapes without changing the rest of the sole.

The sole may also comprise damping elements or elements structurally different from the rest of the sole. For reasons of comfort, it may be relevant to integrate elements having different mechanical properties from the rest of the sole.

Finally, the soleplate may incorporate, in the materials constituting it, but not limited to, intelligent textiles, bioactive textiles, cosmeto-textiles, shape memory materials, hydrocoloidal materials, e-textiles and / or or contain zones / spaces capable of receiving thicknesses intended to improve the well-being of the user (shock absorber, digital technology, microcapsules, nanomaterials ...), thus making the sole an element of the family of "wearable" technologies.

For the entire description, the relative terms such as top, bottom, bottom, top, right, left are to be understood by reference to a sole in use condition, inserted in a shoe, the shoe being worn by an individual .

We can see Fig. 1 a first embodiment of a sole S according to the invention. The main element of the sole S has substantially, when viewed laterally, a Y shape lying down, the lower part of the Y extending towards the front portion 3 of the sole S while the two branches of the Y 's extend towards the rear portion 4 of the sole S. It is seen the upper face 2 of the sole S, intended to be in contact with the foot P of the user and the lower face 1 of the sole S, intended to be in contact with the shoe C of the user.

The two branches of the Y form two strips 5, 6 superimposed one above the other. The first lamella, or lower lamella, 5 is located in the lower part of the sole S, in the vicinity of the lower face 1. The second lamella, or upper lamella, 6 is located in the upper part of the sole S, in the vicinity of the upper face 2.

A housing 7 is provided between the first lamella 5 and the second lamella 6. The housing 7 can accommodate several heel pieces 8. The length of the housing 7 is determined by the length of the second lamella 6 and its meeting point with the first lamella 5. It is understood that the first and second lamella 6, 7 are dimensioned so as to generate a housing 7 the dimensions of which are compatible with effective maintenance of the heel pieces 8.

A tongue 9 is provided at the rear of the sole S. The lower part of the tongue 9 is extended by a base 10 which is inserted under the first lamella 5.

In this way when the sole is in place in a shoe C, pulling on the tongue 9 can lift the sole S by acting on the blade 5 through the base 10. In this way the extraction of the sole S shoe C is facilitated.

Note the presence of a damping element 11 at the front portion 3 of the sole S. The damping element 11 can be replaced by any other device that the user would like to integrate and be welcomed by any part of the sole S .

Finally an insole 12 is present under the face 1 of the sole. This is to show that the sole S according to the invention can be placed on a conventional insole 12. The sole S may be possibly shorter than the sole 12.

It should be noted that the sole illustrated in FIG. 1 to 6, includes a shape memory element which crushes under the weight of the foot.

Fig. 2 and 3 allow to better visualize the structure of a sole S according to the invention. Fig. 2 has a sole S compressed under the action of a foot while Fig. 3 represents a sole S at rest. Note the presence of lateral guides 2a and 2b at the upper face 2 of the sole S. These guides protruding from the upper face 2 towards the outside of the sole and upwards, allow a better maintaining the sole S in the shoe C. The sole shown in FIG. 2 and FIG. 3 does not have a tab. Such a sole could usefully be installed, for example in dance shoes or other similar low shoes.

Fig. 4 illustrates the use of a tongue 9 and its base 10 with the sole S seen in FIG. 2 and 3.

Fig. 5 and 6 are views from above to better understand the shape of a sole according to the invention. The sole shown in Fig. 5 does not include a tab while the sole shown in FIG. 6 comprises a tongue according to another embodiment wherein the tongue has two lateral notches 9a and 9b.

Fig. 7 and 8 allow to apprehend the sole S in situation in a shoe C, and in contact with a foot P for the case of FIG. 7. Note the presence of a damping element 11 which extends longitudinally along a lateral edge of the sole S.

Fig. 9 and 10 illustrate a sole S according to the invention provided with a tongue 9 according to two different embodiments, a foot P coming into contact with the sole S.

Fig. 11 to 22 illustrate numerous variants of embodiment of the sole S. It can be seen in particular that when the tongue 6 is not a single block with the rest of the sole, it is possible to report it in different ways (FIG. 12 to 14).

Fig. 23 to 35 and Fig. 42 to 44 illustrate numerous embodiments of a sole S according to the invention. In particular Fig. 42 illustrates the sole S with the heels 8, Fig. 43 without the heelpieces 8, the tongue 6 being at rest and FIG. 44 illustrates the sole S without the heel pieces 8, the tongue 6 being raised for the insertion of the heels 8.

Fig. 36 to 41 illustrate numerous possibilities for inserting a damping element 11 according to the invention.

Fig. 42 to 69 illustrate many other embodiments of a sole according to the invention.

Note that it is possible to use a second upper blade 6 '(see in particular Fig. 64 and 65) so as to separate the heels 8 in two groups to better maintain them. It is obvious that it is possible to use other slats so as to optimize the maintenance.

In Fig. 56 to 59, we can see a base according to the invention comprising a cap-shaped front portion 13 so as to optimize the maintenance of the sole.

Fig. 60 to 63, we can see a sole having a tongue 15 in the extension of the upper blade 6.

The tongue 15 facilitates the extraction and can also cooperate with slots 14 provided in the base 9 for better support.

The sole according to the invention can be made using many materials and in particular those that the skilled person is used to use. Nevertheless, some materials such as materials used in the pharmaceutical field, such as antibacterial treated latex sponge cloths, multi-stretch non-woven adhesive plaster, hydrocolloidal fabrics, silicones such as, for example, a 1mm thick silicone gel, may be usefully mentioned. whose viscoelastic properties are close to that of the skin, carbon fiber reinforced plastics (CFRP), multidirectional weaves, 3D or 4D, fiber-based, geotextiles, polyurethane foam, cellulosic fibers , leather, viscose, synthetic fibers derived from petroleum such as acrylic, polyester, polyamide, nylon.

Recycled and recyclable textiles are obviously taken into account in the materials used in the sole according to the invention. By way of example, mention may be made of bamboo fiber which may be in the form of pulp in which the material is extremely fine.

Regarding nanomaterials, it will be noted that the nano-coating of polymer membrane microcapsules filled with substance is by far the most common process (cosmetotextiles, microencapsulated active ingredients). Other polymers combine the beneficial action of muscle compression with the properties of bioceramic.

The company HT Concept has developed a bio-elastic polyurethane membrane loaded with metallic microparticles of volcanic origin that capture the infrared radiation, associated by textile coating, it is then applied according to the Body-mapping method to target the zones. of the body solicited.

In the field of non-woven can be mentioned synthetic fibers intended mainly for disposable products for hygiene, medical care.

Intelligent technical textiles (smart textiles, e-textiles for electronic textiles) are textiles that can react by themselves to adapt to their environment. These textiles can incorporate computer components, digital or electronic, but also innovative polymer materials such as shape memory polymers etc ...

Smart textiles are part of the broad field of wearable technologies.

Smart clothing has an extra function than clothing.

When perspiration rises, perspiration dissolves a substance causing a heat-absorbing reaction. To obtain this type of reaction, other manufacturers rely on two-component fiber spinning.

This technique involves extruding different polymers without mixing them to combine their respective properties. Other active polymers for air-conditioned clothing are revolutionary, such as the company Soleta, which developed with Luxilon Industries, a fiber whose cooling properties are not based on the addition of phase change materials (PCM) or on the composition lament but on the structure of the base polymer. Thanks to the alternation of its hydrophobic and hydrophilic molecules which simultaneously ensure the evaporation of perspiration and the thermal conductivity. It functions as a pump that absorbs moisture from the body while giving off freshness.

This polymer provides yarns suitable for knitting sports equipment.

The manufacturers have developed bi-elastic fabrics whose strength is the ability of multidimensional elongations which allows to marry at best the movements of the body and to obtain a second skin effect. Beyond comfort, these textiles have useful properties in terms of performance,

With muscle compression, they stimulate blood circulation and improve oxygenation, which is beneficial during recovery after exercise. Another advantage is that they provide better muscle support. This reduces vibration and therefore the loss of energy and the risk of micro-lesions. The advent of synthetic fibers in the textile industry has not only optimized the spinning processes of weaving ... they have also revolutionized the making of clothing (fabrics).

Less radical than the non-woven, seamless techniques (seamless on the sides).

Two other techniques make it possible to manufacture seamless articles: 1 / Use of ultrasound: the vibratory phenomenon of the wave caused by sound, converted into heat, makes it possible to assemble the parts together. 2 / Thermo-bonding: this technique makes it possible to eliminate the elastics by offering edges cut to frankness.

Manufacturers must design new fibers that meet the new expectations of the public related to mobility, health and well-being, (the interaction of textiles with the human body is one of the priority axis of development for functional textiles, polysensoriality and well-being linked to sport, mobility, health, aging (for example a fabric that changes color in case of fever, clothes that are refreshing, so it is important that these fibers be natural, synthetic, bio-sourced or mixed, provided that they are multifunctional, saving energy and raw materials and better still recyclable The factory of the future: the textile is labor intensive It is important to find assembling methods that are easier like knitting in 3D to produce at lower cost and possibly being able to relocate production sites .

Molding techniques and for example sand casting and polystyrene molding known as the Lost Foam PMP process, injection molding, bimetallic molding, spin molding (for composites, reinforcement plus resin) , flexible impression molding, ect ...

We can also consider adding new functions to the sole such as: - protect external risks through communicating tissues, - diagnose and deliver drugs via plasters with microprocessors, - control the outside temperature, presence of gas toxic, UV index ... - monitor vital parameters such as body temperature, insulin level, respiration, heart rate ... - warn the user and his doctor in case of danger, using fleas or built-in sensors, - consolidate bone reconstruction using a strong reinforcement textile, - better eliminate perspiration, prevent bacterial or fungal infections, retain heat thanks for example to silver composite textile fibers, - improve comfort with textiles techniques capable of providing sound insulation and air filtration, - resisting tasks and life to reduce odors and bring aromas with changing fragrances, energizing the morning, soothing at night ... - bring comfort, safety, performance thanks to the lightness, the resistance to 1 abrasion and tearing, - breathability (impermeability to water and permeability to perspiration) relevant for sportswear, - integrate a transmitter responsible for transmitting digital signals, via a detector controlling the sports activity, the body temperature, the climate, the degree of humidity and ozone, level of ultraviolet light, heart rate to transmit to hospital or medical center, running speed, distance traveled, - promoting well-being and health with cosmetotextiles , and provide an antistress, antiperspirant, antipollution, insecticide, anti-bacterial and / or contain microcapsules in which are incorporated oils essential or moisturizing products diffused in contact with the skin, - communicate with conductive textiles such as e-textiles, capable of storing energy.

In addition, the sole may comprise non-slip zones, for example using notches or any other aggressive geometry made of soft and durable rubber. Notches will provide maximum flexibility.

Many embodiments have been described but those skilled in the art will be able to make other combinations from the technical characteristics described here, without departing from the scope of the invention.
