Description

Campo de la invención La presente invención se refiere a un calzado mejorado que realiza una distribución de presiones plantares y presenta una cámara de aire en la zona del corte, mediante la aplicación de tejidos tridimensionales específicamente concebidos para este efecto. La Field of the Invention The present invention relates to an improved footwear that performs a distribution of plantar pressures and presents an air chamber in the cutting area, by applying three-dimensional fabrics specifically designed for this purpose. The

10 invención es de aplicación en la industria textil, concretamente en la industria de fabricación de calzado. The invention is applicable in the textile industry, specifically in the shoe manufacturing industry.

Antecedentes de la invención Es necesidad para la confortabilidad de cualquier tipo de calzado que sus componentes Background of the invention It is necessary for the comfort of any type of footwear that its components

15 permitan la evaporación del calor y humedad que se generan en el interior del calzado a la vez que debe impedir que los líquidos provenientes del exterior penetren y entren en contacto con la piel. 15 allow the evaporation of heat and humidity that are generated inside the footwear while preventing liquids from outside from entering and coming into contact with the skin.

En los calzados presentes en el mercado, se pueden encontrar diferentes propuestas In the footwear present in the market, different proposals can be found

20 encaminadas a favorecer la evacuación de la humedad ambiental que se genera en el entorno del pie ocluido por el zapato. 20 aimed at favoring the evacuation of the environmental humidity that is generated in the environment of the foot occluded by the shoe.

Así pues, existen numerosos tipos de cortes de calzado compuestos por forro y parte exterior, en los que se integra entre ellos membranas que permiten la evaporación de la Thus, there are numerous types of shoe cuts composed of lining and outside, in which membranes that allow evaporation of the fabric are integrated

25 humedad que el cuerpo humano genera en el pie sin permitir la entrada del agua o líquidos del exterior. También existen numerosos tipos de cortes de calzado que presentan una estructura microperforada cuyo fin es el mismo, esto es eliminar la humedad y calor generados. 25 moisture that the human body generates in the foot without allowing the entry of water or liquids from outside. There are also numerous types of shoe cuts that have a microperforated structure whose purpose is the same, that is to eliminate the humidity and heat generated.

30 De la misma manera, para aliviar el exceso de calor en la zona de apoyo del pie casi la totalidad de las plantillas, entresuelas o incluso algunas suelas, presentan perforaciones para que esta zona pueda "respirar", que no es otra cosa que favorecer la salida de la humedad cargada de calor acumulada por la acción combinada del metabolismo con el ambiente cerrado de los calzados. 30 In the same way, to relieve excess heat in the foot support area, almost all of the insoles, midsole or even some soles, have perforations so that this area can "breathe", which is nothing to favor the output of moisture loaded with heat accumulated by the combined action of the metabolism with the closed environment of the footwear.

La necesidad de todos estos materiales nace porque el cuerpo humano suda, como mecanismo de refrigeración del propio cuerpo, se debe considerar que la evaporación del sudor depende del gradiente de presión de vapor de agua entre el cuerpo y el aire, por ejemplo, en un ambiente muy cálido y muy húmedo el cuerpo humano apenas es capaz de sudar. The need for all these materials is born because the human body sweats, as a cooling mechanism of the body itself, it must be considered that the evaporation of sweat depends on the water vapor pressure gradient between the body and the air, for example, in a Very warm and very humid environment the human body is barely able to sweat.

Una vez el sudor ha salido del cuerpo, ese sudor se debe eliminar de la piel mediante evaporación para permitir que el mecanismo de refrigeración siga funcionando, por tanto, si el ambiente que rodea a la piel es muy cálido y húmedo el sistema de refrigeración se bloquea y deja de funcionar. Once the sweat has left the body, that sweat must be removed from the skin by evaporation to allow the cooling mechanism to continue working, therefore, if the environment around the skin is very hot and humid the cooling system will Block and stop working.

Así pues, asegurar la continuidad de funcionamiento de la refrigeración humana es parte inherente de todo aquello que vaya a servir de envolvente de la piel, y más concretamente en el calzado cerrado, por motivo de la propia cerrazón del zapato y de que existe una acción metabólica mayor en los pies en movimiento que hace que su sistema sudorípara sea más activo. Thus, ensuring the continuity of the operation of human refrigeration is an inherent part of everything that will serve as a skin envelope, and more specifically in closed footwear, because of the shoe's own closure and that there is an action Major metabolic in moving feet that makes your sweat system more active.

Favorecer la extracción del sudor también está relacionada con el beneficio que supone tener la piel seca en un ambiente donde el roce con el calzado es continuo, ya que esta piel, si está continuamente mojada, se reblandece y es más fácil que se rompa, apareciendo heridas. Promoting the extraction of sweat is also related to the benefit of having dry skin in an environment where the rubbing with footwear is continuous, since this skin, if it is continuously wet, softens and is easier to break, appearing wounds

Evidentemente, favorecer la evaporación sin dejar entrar los liquidas desde el exterior, radica en alcanzar un equilibrio entre el tamaño molecular de la gota, el del vapor y el del tamaño del poro que permita el paso de uno impidiendo el del otro. A mayor tamaño de poro mayor facilidad, tanto en la evaporación como en la penetración de líquidos desde el exterior, por tanto y para mantener la impermeabilidad, se sacrifica velocidad de transpiración, con materiales de poro reducido. Obviously, favoring evaporation without letting liquids in from the outside, lies in reaching a balance between the molecular size of the drop, the vapor and the pore size that allows the passage of one preventing the other. The larger the pore size, the easier it is, both in evaporation and in the penetration of liquids from the outside, therefore, and in order to maintain impermeability, the perspiration rate is sacrificed, with reduced pore materials.

Así pues, con velocidades moderadas o bajas de transmisión de humedad al exterior, la piel y el ambiente circundante siguen húmedos, y por tanto las problemáticas asociadas que se han comentado anteriormente siguen presentes, aunque mitigadas porque si existe evaporación pero, si bien el equilibrio está desplazado, las condiciones ambientales dentro del calzado mejoran sustancialmente en comparación a no emplear Thus, with moderate or low speeds of transmission of humidity to the outside, the skin and the surrounding environment are still moist, and therefore the associated problems that have been mentioned above are still present, although mitigated because there is evaporation but, although the balance is displaced, the environmental conditions inside the footwear improve substantially compared to not using

estos materiales permeables o porosos y por eso están amplia y abundantemente implementados en el sector. These permeable or porous materials and therefore are widely and abundantly implemented in the sector.

En otro orden de factores que afectan a la usabilidad de los calzados, se encuentran las In another order of factors that affect the usability of footwear, are the

5 plantillas o formas internas de las partes de apoyo, no ya por su permeabilidad o no a los agentes anteriormente mencionados, sino por su grado de ayuda a apoyar mejor y de forma más estable el pie en la pisada, caminar mejor, distribución de impactos de pisada, adaptabilidad a la forma de la planta de las personas, reducción de las vibraciones transmitidas a otras articulaciones, etc ... 5 templates or internal forms of the support parts, not because of their permeability or not the agents mentioned above, but for their degree of help to better support and more stably foot on the tread, walk better, distribution of impacts of tread, adaptability to the shape of people's plant, reduction of vibrations transmitted to other joints, etc ...

10 Son ampliamente conocidas un sinfín de plantillas técnicas destinadas al uso laboral o por parte de gente con problemáticas espeCíficas, cuyo porcentaje es muy elevado ya que las formas plantares varian mucho, teniendo, por ejemplo, varios grados de curvatura en el puente plantar para ir desde un pie plano a un pie cavo que provocan 10 A wide range of technical templates for work use or by people with specific problems are widely known, whose percentage is very high since the plantar forms vary greatly, having, for example, several degrees of curvature in the plantar bridge to go from a flat foot to a cavo foot that cause

15 distintas pronaciones perjudiciales. 15 different harmful pronations.

Estas plantillas destinadas a la mejora de la salud de los pies y de las articulaciones relacionadas con las fuerzas de impacto al caminar, están conformados, o bien por materiales duros con la forma correcta de una planta a fin de forzar al pie que se apoya These templates designed to improve the health of the feet and joints related to the impact forces when walking, are formed, or hard materials with the correct shape of a plant in order to force the foot that rests

20 sobre ellos a que se acople a lo que debiera ser una pisada correcta de la persona, pero que aporta incomodidad al no acoplarse la plantilla a la forma del pie; o bien por materiales de gel o de gran absorción de impactos y buena recuperación elástica al dejar de soportar la presión del impacto y la pisada. 20 on them to be coupled to what should be a correct step of the person, but that brings discomfort not to fit the template to the shape of the foot; Either by gel materials or high impact absorption and good elastic recovery by ceasing to withstand the pressure of the impact and the tread.

25 En cualquiera de los anteriores dos casos, los artículos presentan propiedades beneficiosas, si bien a costa de evitar cualquier tipo de transpirabilidad y paso de calor y humedad. Además, estos materiales suelen tener un ciclo de vida muy limitado y, tanto por este motivo como por la imposibilidad de integración como parte componente del calzado, son articulos extraíbles y que muchas veces se mueven o no se acoplan bien 25 In either of the previous two cases, the articles have beneficial properties, although at the cost of avoiding any type of breathability and passage of heat and humidity. In addition, these materials usually have a very limited life cycle and, both for this reason and for the impossibility of integration as a component part of the footwear, they are removable items and that often move or do not fit well

30 las hormas de los calzados, dado que no están hechos exprofeso para un diseño de calzado concreto. 30 shoe lasts, since they are not made exprofeso for a design of concrete footwear.

Así pues, surge la necesidad de desarrollar un calzado en el que exista una cámara de aire en la mayor parte posible de la superficie circundante del pie para que actúe como Thus, there is a need to develop a shoe in which there is an air chamber in the largest possible part of the surrounding surface of the foot so that it acts as

35 receptor del calor y la humedad, alejándolos de la piel y manteniéndola seca y fresca, mientras tiene lugar la evaporación de dicho calor y humedad hacia el exterior del calzado. Además, también se hace necesario en dicho calzado, que los materiales que generan la mencionada cámara de aire, se puedan disponer en la parte inferior del calzado destinada el apoyo plantar del pie, manera que tengan una recuperación elástica y una resistencia a la deformación tal, que reparta de manera eficaz las presiones cuando se realiza presión sobre los materiales y a la vez mantengan abierta la cámara de aire. 35 receiver of heat and humidity, moving them away from the skin and keeping it dry and fresh, while evaporation of said heat and moisture to the outside of the footwear takes place. In addition, it is also necessary in said footwear, that the materials generated by the aforementioned air chamber, can be arranged in the lower part of the footwear for the plantar support of the foot, so that they have an elastic recovery and a resistance to deformation such , which effectively distributes the pressures when pressure is placed on the materials and at the same time keep the air chamber open.

Descripción detallada de la invención A la vista de lo anteriormente enunciado y haciendo referencia a la numeración adoptada en las figuras , el objeto de la invención es un calzado que ofrece unas caracteristicas DETAILED DESCRIPTION OF THE INVENTION In view of the foregoing and referring to the numbering adopted in the figures, the object of the invention is a shoe that offers characteristics

20 técnicas de amortiguación y aireación de la planta del pie, y de aireación y capacidad de evacuar calor por la zona del corte del calzado, que no se encuentran en ningún calzado de los conocidos en el estado de la técnica. 20 techniques of cushioning and aeration of the sole of the foot, and of aeration and ability to evacuate heat through the area of the shoe cut, which are not found in any footwear known in the state of the art.

El calzado objeto de la invención comprende dos partes diferenciadas en las que se The footwear object of the invention comprises two distinct parts in which

25 emplean dos textiles tridimensionales diferentes entre sí, dado que las caracteristicas que se les exige a los dos textiles tridimensionales son distintas: estas dos partes son la zona de la planta (1) donde se localiza un primer tejido tridimensional (2) y la zona del corte (3) donde se localiza un segundo tejido tridimensional (4). 25 employ two different three-dimensional textiles, given that the characteristics required of the two three-dimensional textiles are different: these two parts are the area of the plant (1) where a first three-dimensional fabric (2) is located and the area of the cut (3) where a second three-dimensional fabric (4) is located.

30 Un tejido tridimensional es un elemento único obtenido por tejeduría en el que la cara tejida superior se obtiene por la acción de una barra de agujas que tejen un tipo de hilo, mientras que al mismo tiempo otra barra de agujas situada en paralelo y a una distancia D teje otro hilo que forma la cara tejida inferior del tejido. Al mismo tiempo, la distancia O es recorrida perpendicularmente a las barras de agujas por un tercer hilo que teje en 30 A three-dimensional fabric is a unique element obtained by weaving in which the upper woven face is obtained by the action of a needle bar that weave a type of thread, while at the same time another needle bar located in parallel and at a distance D weave another thread that forms the bottom woven side of the fabric. At the same time, the distance O is traveled perpendicularly to the needle bars by a third thread that weaves in

35 las dos barras de agujas, formando un cuerpo unico de tres dimensiones La zona de la planta (1) del zapato es una zona que requiere que se distribuyan las presiones que se reciben , las cuales son infinitamente diversas por ser completamente distinta la manera de pisar de cada persona, asi pues, el primer tejido tridimensional (2) proporciona unas caracteristicas de resistencia y resiliencia que permiten esa distribución de presiones, mediante la creación de una cámara de aire que nunca se cierra, ya que nunca se apoya toda la superficie del pie con las mismas presiones máximas que la cerrarían, máxime al caminar, y ya que en el momento en que un usuario deja de ejercer presión sobre la cámara de aire el primer textil tridimensional recupera su geometría inicial. 35 the two needle bars, forming a unique three-dimensional body The area of the sole (1) of the shoe is an area that requires that the pressures received be distributed, which are infinitely diverse because the manner in which they are completely different stepping on each person, thus, the first three-dimensional fabric (2) provides resistance and resilience characteristics that allow this pressure distribution, by creating an air chamber that never closes, since the entire surface is never supported of the foot with the same maximum pressures that would close it, especially when walking, and since at the moment when a user stops exerting pressure on the air chamber the first three-dimensional textile recovers its initial geometry.

Así pues, el primer tejido tridimensional (2) situado en la zona de la planta (1) vuelve a ejercer su efecto de repartir presiones y absorber fuerzas en el siguiente paso o impacto. Además, el movimiento de abertura de la cámara de aire junto con su cierre parcial al verse sometida a presión, generan un efecto de convección y de transmisión de corrientes de aire que genera una renovación y aireación del ambiente por debajo de la zona de la planta. Thus, the first three-dimensional fabric (2) located in the area of the plant (1) once again exerts its effect of distributing pressures and absorbing forces in the next step or impact. In addition, the opening movement of the air chamber together with its partial closure when subjected to pressure, generate a convection effect and transmission of air currents that generates a renewal and aeration of the environment below the plant area .

El primer tejido tridimensional (2) empleado en la zona de la planta (1 ) del calzado objeto de la invención comprende una cara tejida superior (5) y una cara tejida inferior (6) con una zona intermedia (7) entre la cara tejida superior (5) y la cara tejida inferior (6), donde se aloja un hilo intermedio. The first three-dimensional fabric (2) used in the area of the floor (1) of the footwear object of the invention comprises an upper woven face (5) and a lower woven face (6) with an intermediate zone (7) between the woven face upper (5) and the lower woven face (6), where an intermediate thread is housed.

El hilo intermedio de la zona intermedia (7) del primer tejido tridimensional (2) es un monofilamento con las características técnicas siguientes: tiene una altura entre la cara tejida superior (5) y la cara tejida inferior (6) mayor a 5 mm, tiene un diámetro de entre 0,18 y 0,22 mm, y la densidad de hilo entre la cara tejida superior (5) y la cara tejida inferior (6) es de entre 5 y 12 filamentos por cm2; considerando lo anterior el primer tejido tridimensional (2) tiene un espesor mayor a 5mm. El monofilamento es perpendicular tanto a la cara tejida superior (5) como a la cara tejida inferior (6). The intermediate thread of the intermediate zone (7) of the first three-dimensional fabric (2) is a monofilament with the following technical characteristics: it has a height between the upper woven face (5) and the lower woven face (6) greater than 5 mm, it has a diameter of between 0.18 and 0.22 mm, and the thread density between the upper woven face (5) and the lower woven face (6) is between 5 and 12 filaments per cm2; considering the above, the first three-dimensional fabric (2) has a thickness greater than 5mm. The monofilament is perpendicular to both the upper woven face (5) and the lower woven face (6).

Más preferentemente de la zona intermedia (7) el monofilamento tiene preferentemente una altura entre 7 y 11 mm. More preferably from the intermediate zone (7) the monofilament preferably has a height between 7 and 11 mm.

Tanto el tipo de hilo de la cara tejida superior (5), como el tipo hilo de la cara tejida inferior (6), como el monofilamento de la zona intermedia (7), en la realización preferente de la invención, son de poliéster, pero puede ser de cualquier material sintético no hidrófilo, como por ejemplo la poliamida o el polietilenio. Both the type of yarn of the upper woven face (5), and the type of yarn of the lower woven face (6), as the monofilament of the intermediate zone (7), in the preferred embodiment of the invention, are polyester, but it can be of any non-hydrophilic synthetic material, such as polyamide or polyethylene.

Tanto el espesor del primer tejido tridimensional (2), como el diámetro del monofila mento empleado, y la densidad de monofilamentos empleada en el primer tejido tridimensional (2), son las características técnicas que proporcionan las características de reparto de presiones bajo una presión y recuperación de la forma inicial una vez la presión cesa, que no se obtienen en ninguna solución de las conocidas en el estado de la técnica, asi como se mejora enormemente la capacidad de aireación del pie. Both the thickness of the first three-dimensional fabric (2), and the diameter of the monofilament used, and the density of monofilaments used in the first three-dimensional fabric (2), are the technical characteristics that provide the characteristics of pressure distribution under a pressure and recovery of the initial form once the pressure ceases, which are not obtained in any solution known in the state of the art, as well as the aeration capacity of the foot is greatly improved.

Igualmente es el monofilamento con la altura que presenta, el que genera la cámara de aire que permite la aireación continua de la zona de la planta del pie, mejorando las condiciones de temperatura del pie. It is also the monofilament with the height that it presents, which generates the air chamber that allows continuous aeration of the area of the sole of the foot, improving the temperature conditions of the foot.

El primer tejido tridimensional (2), en el calzado objeto de la invención, está formado por tejeduria de género de punto por urdimbre. The first three-dimensional fabric (2), in the footwear object of the invention, is formed by knitting knitting by warp.

Respecto a la zona del corte (3) del calzado objeto de la invención, como ya se ha expuesto dicha zona comprende un segundo tejido tridimensional (4), cuya función es radicalmente opuesta al primer tejido tridimensional (2), ya que debe deformarse fácilmente y adaptarse a cualquier imperfección del pie sin tener que recuperar la forma anterior ni ejercer presión sobre la zona del pie con la que está en contacto. Regarding the area of the cut (3) of the footwear object of the invention, as said area has already been exposed, it comprises a second three-dimensional fabric (4), whose function is radically opposite to the first three-dimensional fabric (2), since it must be easily deformed and adapt to any imperfection of the foot without having to recover the previous form or exert pressure on the area of the foot with which it is in contact.

Con el segundo tejido tridimensional (4) se crea una cámara de aire que es deformable a poco que el pie ejerza una presión sobre él, de manera que el segundo tejido tridimensional (4) se adapte por la parte interior a las diferentes formas que pueda tener un pie más allá de lo que permita la horma del calzado With the second three-dimensional fabric (4) an air chamber is created that is deformable as soon as the foot exerts a pressure on it, so that the second three-dimensional fabric (4) adapts on the inside to the different shapes that it can have one foot beyond what the shoe last allows

El segundo tejido tridimensional (4) comprende una cara tejida superior (8) y una cara tejida inferior (9) con una zona intermedia (10) entre la cara tejida superior (8) y la cara tejida inferior (9). The second three-dimensional fabric (4) comprises an upper woven face (8) and a lower woven face (9) with an intermediate zone (10) between the upper woven face (8) and the lower woven face (9).

La zona intermedia (10) del segundo tejido tridimensional (4) aloja un hilo que puede ser un monofilamento de diámetro entre 0,06mm y 0,14mm o un multifilamento de grosor equivalente a los anteriores. Además, la zona intermedia (10) tiene una altura entre la cara tejida superior (8) y la cara tejida inferior (9) de entre 3 y 5mm de altura. The intermediate zone (10) of the second three-dimensional fabric (4) houses a thread that can be a monofilament with a diameter between 0.06mm and 0.14mm or a multifilament of thickness equivalent to the previous ones. In addition, the intermediate zone (10) has a height between the upper woven face (8) and the lower woven face (9) between 3 and 5mm high.

La cara tejida superior (8) del segundo tejido tridimensional (4) es de un polímero hidrófilo mientras la cara tejida inferior (9) del segundo tejido tridimensional (4) es de material hidrófobo. Estas diferentes composiciones y su ubicación, tienen por objetivo mantener seca la superficie que va a estar cerca de la piel y que el tejido de material The upper woven face (8) of the second three-dimensional fabric (4) is of a hydrophilic polymer while the lower woven face (9) of the second three-dimensional fabric (4) is of hydrophobic material. These different compositions and their location are intended to keep the surface that will be close to the skin dry and that the tissue material

10 hidrófilo, el más externo, por efecto de la capilaridad, haga de atrayente de la humedad y de almacén de la misma de manera que evite que por gravedad la humedad caiga y salga de la cámara de aire y se mantenga cerca de la piel del pie. 10 hydrophilic, the outermost, due to the capillary effect, acts as an attractant for moisture and stores it in such a way that it prevents gravity from falling and leaving the air chamber and keeping it close to the skin of the foot.
