Campo de aplicacion de la invencionField of application of the invention

El campo de aplicacion de la presente invencion se enmarca dentro del sector de la industria dedicada a la fabrication de calzado, centrandose particular y especlficamente en el ambito de la fabricacion de suelas de goma y materiales similares obtenidos por molde.The field of application of the present invention is part of the sector of the industry dedicated to the manufacture of footwear, focusing particularly and specifically in the field of the manufacture of rubber soles and similar materials obtained by mold.

Antecedentes de la invencionBackground of the invention

Como referencia al estado actual de la tecnica, cabe senalar que existen en el mercado multiples modelos de suelas para calzado que presentan infinidad de formas y configuraciones distintas, algunas simplemente esteticas y otras con finalidades concretas, normalmente para mejorar el agarre o aligerar el material o para ambas cosas. Un ejemplo de ello es el documento de modelo de utilidad ES1103684U, cuyo titular es el propio solicitante.As a reference to the current state of the art, it should be noted that there are multiple models of soles for shoes that have a lot of different shapes and configurations, some simply aesthetic and others with specific purposes, normally to improve the grip or lighten the material or for both. An example of this is the utility model document ES1103684U, whose owner is the applicant itself.

Por otra parte, existen multiples modelos de suelas, normalmente para calzado deportivo, que presenta estructuras especialmente disenadas para proporcionar sistemas de amortiguacion que absorben el impacto de la pisada. Sin embargo, ademas de estar normalmente destinadas exclusivamente para calzado deportivo, suele tratarse de complejas estructuras con multiples materiales acoplados entre si y/o camaras de aire.On the other hand, there are multiple models of soles, usually for sports shoes, which has structures specially designed to provide cushioning systems that absorb the impact of the tread. However, in addition to being normally used exclusively for sports shoes, it is usually complex structures with multiple materials coupled together and / or air chambers.

Sin embargo, al menos por parte del solicitante, se desconoce la existencia de ninguna otra suela para calzado, ya sea deportivo o de calle, ni ninguna otra invencion de aplicacion similar, que, siendo de goma, presente unas caracterlsticas tecnicas, estructurales y constitutivas que sean iguales o semejantes a las que presenta la que aqul se reivindica y proporcione un sistema de amortiguacion tan simple pero efectivo.However, at least on the part of the applicant, the existence of any other sole for footwear, either sports or street, or any other similar application is not known, which, being rubber, presents a technical, structural and constitutive characteristics that they are the same or similar to the one presented here and that it provides a simple but effective damping system.

Explication de la invencionExplanation of the invention

La suela para calzado que la invencion propone permite alcanzar satisfactoriamente los objetivos anteriormente senalados, estando los detalles caracterizadores que lo hacen posible y que la distinguen convenientemente recogidos en las reivindicaciones finales que acompanan a la presente description.The sole for footwear proposed by the invention makes it possible to satisfactorily achieve the aforementioned objectives, the details that make it possible being possible and which distinguish it conveniently included in the final claims that accompany the present description.

Mas concretamente, lo que la invencion propone, tal como se ha apuntado anteriormente, es una suela para calzado de goma obtenida por moldeo, preferentemente de goma EVA (etileno vinil-acetato), que se distingue por presentar un particular diseno estructural, basado en la existencia de una serie de barras estabilizadoras, fragmentadas, inclinadas e independientes entre si, que esta especialmente estudiado para proporcionar un sistema de amortiguacion y recuperacion del impulso que absorbe la energla producida por el impacto de la pisada, aportando maximo confort al caminar y disminuyendo la fatiga.More specifically, what the invention proposes, as pointed out above, is a sole for rubber footwear obtained by molding, preferably of EVA rubber (ethylene vinyl acetate), which is distinguished by having a particular structural design, based on the existence of a series of stabilizer bars, fragmented, inclined and independent of each other, which is specially designed to provide a system of damping and impulse recovery that absorbs the energy produced by the impact of the tread, providing maximum comfort when walking and reducing fatigue.

Mas especlficamente, la suela de la invention, conformada de manera convencional a partir de un cuerpo sensiblemente plano y de cierto grosor presenta, al menos en su parte anterior, es decir, la que queda en correspondencia con la parte anterior del pie, una zona central de amortiguacion que, en la cara que determina su superficie inferior o externa, la que queda en contacto con el suelo, constituye un vaciado de material conformado por una pluralidad de huecos cuya particular estructura define las citadas barras estabilizadoras, fragmentadas, inclinadas e independientes entre si que, ademas del aligeramiento, proporcionan el efecto amortiguante de la suela al plegarse bajo la presion de la pisada y tender a recuperar su posicion original.More specifically, the sole of the invention, formed conventionally from a substantially flat body and of a certain thickness, has, at least in its anterior part, that is, the one that remains in correspondence with the anterior part of the foot, an area central buffer that, in the face that determines its bottom or outer surface, which remains in contact with the ground, constitutes a void of material formed by a plurality of holes whose particular structure defines the said stabilizer bars, fragmented, inclined and independent among themselves that, in addition to lightening, they provide the cushioning effect of the sole when folding under the pressure of the tread and tend to recover their original position.

Ello es asl gracias a que dichas barras conforman una serie de tabiques paralelos dispuestos en hileras, determinados por sucesivos huecos intercalados entre ellos, los cuales tabiques, ademas, estan segmentados en porciones semejantes mediante aberturas practicadas en ellos que abren canales entre los huecos contiguos que los determinan desde su misma base, estando dichas aberturas desplazadas, las de una hilera de tabiques y la contigua, al tres bolillo, formando asl un circuito interno de distribution y recirculation del aire.This is due to the fact that said bars form a series of parallel partitions arranged in rows, determined by successive gaps interspersed between them, which partitions are also segmented in similar portions by openings made in them that open channels between adjacent gaps. they are determined from the same base, said openings being displaced, those of a row of partitions and the adjoining one, to the three bolillo, thus forming an internal circuit of distribution and recirculation of the air.

Ademas, todos estos tabiques que forman dichas hileras de segmentos emergen de la base del vaciado, entre cada par de huecos, hacia la superficie del cuerpo de la suela con una cierta inclination hacia adelante, es decir, que no es perpendicular a dicha superficie, sino que presenta un angulo de aproximadamente 25°, estando el extremo distal de los mismos orientado hacia la punta de la parte anterior de la suela.Furthermore, all these partitions forming said rows of segments emerge from the base of the recess, between each pair of recesses, towards the surface of the body of the sole with a certain forward inclination, that is to say, that is not perpendicular to said surface, but it has an angle of approximately 25 °, the distal end thereof being oriented towards the tip of the anterior part of the sole.

De este modo, al producirse la compresion de la suela con la pisada, dichos tabiques se aplastan todos en la misma direction como barras estabilizadoras, forzando, gracias al material de goma EVA con que esta conformada la suela, y el descrito circuito de canales de aire que determinan su recuperacion tambien con todos ellos orientados hacia el mismo lado, de manera que devuelven la fuerza entregada acortando los tiempos de recuperacion.Thus, when the compression of the sole with the step is produced, said partitions are crushed all in the same direction as stabilizer bars, forcing, thanks to the EVA rubber material with which the sole is formed, and the described circuit of channels of air that determine their recovery also with all of them oriented towards the same side, so that they return the force delivered shortening the recovery times.

La descrita estructura proporciona, pues, un perfecto y simple sistema de amortiguacion que absorbe la energla producida por el impacto en la pisada, aportando maximo confort al caminar y disminuyendo la fatiga. Se adapta a la anatomla plantar, dado que, al menos, se incluye en la zona central de la parte anterior de la suela, donde el impacto de la pisada en mayor, generando un efecto amortiguador-relajante y neutralizando los impactos y las presiones al caminar.The described structure provides, therefore, a perfect and simple damping system that absorbs the energy produced by the impact on the tread, providing maximum comfort when walking and reducing fatigue. It adapts to the plantar anatomy, since, at least, it is included in the central area of the anterior part of the sole, where the impact of the tread increases, generating a cushioning-relaxing effect and neutralizing the impacts and pressures walk.

Ademas, gracias a las cualidades del material de goma EVA con que, preferentemente, esta fabricada la suela, la recuperacion elastica de las descritas barras estabilizadoras perdura toda la vida util de la suela.In addition, thanks to the qualities of the EVA rubber material with which, preferably, the sole is manufactured, the elastic recovery of the stabilizer bars described last the entire life of the sole.

Por ultimo cabe destacar que la descrita estructura es perfectamente compatible con su implementation en una suela de las disenadas con vaciados de ahorro y aligeramiento de material, por ejemplo una suela que comprenda, en la cara que constituye su superficie superior o interna, una ranura, que define un recorrido equidistante al borde su parte anterior estableciendo una zona central y otra perimetral y que, por la cara inferior o externa, determina un nervio flanqueado por sendos canales que lo separan de la zona central y perimetral respectivamente estando dicha zona central conformada por el descrito conjunto de barras estabilizadoras determinadas por los antedichos huecos y tabiques segmentados e inclinados.Finally, it should be noted that the described structure is perfectly compatible with its implementation in a sole of those designed with savings and lightening of material, for example a sole that comprises, in the face that constitutes its upper or internal surface, a groove, that defines a distance equidistant to the edge of its front part, establishing a central zone and another perimeter and that, on the lower or outer side, determines a nerve flanked by separate channels that separate it from the central and perimeter zone respectively said central zone being formed by the described set of stabilizing bars determined by the above-mentioned segmented and inclined hollows and partitions.
