Description
Piso para calzado.Floor for footwear.
La presente invención se refiere a un piso para calzado, de los destinados a complementarse con el correspondiente corte, piso concebido y estructurado en orden a permitir dilataciones tanto transversales como verticales, con el fin de absorber los sobre-esfuerzos que al andar el pie genera sobre el calzado.The present invention relates to a floor for footwear, of those intended to complement the corresponding court, floor conceived and structured in order to allow both transverse and vertical dilations, in order to absorb the over-efforts that when walking the foot generated on footwear.
Así pues, el objeto de la invención es conseguir un piso para calzado que ofrezca al usuario del mismo una plena confortabilidad al ser capaz de deformarse por efecto del peso corporal del usuario, absorbiendo los esfuerzos generados por éste último, a la vez que adecuarse también al notable incremento de anchura que sufre el pie a nivel de la planta, cuando es esta zona del mismo la que recibe la carga corporal.Thus, the object of the invention is to achieve a floor for footwear that offers its user a full comfort to be able to deform by weight effect body of the user, absorbing the efforts generated by it last, while also adapting to the notable increase in width suffered by the foot at the level of the floor, when is this area from it the one that receives the body load.
Al inicio de la marcha todo el peso del cuerpo recae sobre el talón del pie, mientras que a medida que avanza el pie contrario el peso se concentra sobre la planta del pie. Por otro lado el pie está anatómicamente configurado para caminar descalzo y por terrenos blandos, de manera que se produce un efecto de amortiguación sobre el suelo, acompañado de un notable ensanchamiento del pie a nivel de la planta que puede llegar a ser del orden de 10 mm. Sin embargo en la práctica se utilizan diferentes tipos de calzado que presentan como denominador común una sustancial rigidez a nivel de su piso, de manera que ni amortiguan el peso corporal cuando se carga sobre el tacón, ni permiten el ensanchamiento del pie cuando la zona de presión se traslada a la planta del zapato.At the start of the march the whole body weight falls on the heel of the foot, while as the opposite foot the weight is concentrated on the sole of the foot. For another side the foot is anatomically configured to walk barefoot and through soft terrain, so that there is an effect of cushioning on the ground, accompanied by a remarkable foot widening at the level of the floor that can become of the order of 10 mm. However in practice they are used different types of footwear that present as a common denominator a substantial stiffness at the level of your floor, so that neither cushion body weight when loaded on the heel, nor do they allow foot widening when the pressure zone moves to the shoe plant.
Esto trae consigo, evidentemente, que las condiciones de uso de un zapato o cualquier otro calzado sean totalmente dispares respecto de lo anatómicamente correcto.This obviously leads to the conditions of use of a shoe or any other footwear totally disparate with respect to anatomically correct.
Tratando de obviar este problema el propio solicitante es titular de los Modelos de Utilidad con números de solicitud 200400736 y 200400737 (PCT ES05000018) en la que se describe un calzado ergonómico, cuya suela es elásticamente deformable en sentido transversal a nivel de la planta, de manera que permite el citado ensanchamiento de dicha planta cuando el peso corporal se carga sobre la misma, y la recuperación posterior al cesar dicha presión.Trying to ignore this problem himself applicant is holder of the Utility Models with numbers of application 200400736 and 200400737 (PCT ES05000018) in which describes an ergonomic footwear, whose sole is elastically deformable transversely at the plant level, so which allows the said widening of said plant when the weight body is loaded on it, and post-recovery stop said pressure.
Sin embargo queda sin resolver el problema inherente a la deformabilidad de la suela en sentido de aplastamiento de la misma, en particular cuando se produce la carga corporal a través del talón y sobre la zona del tacón del piso.However, the problem remains unresolved. inherent in the deformability of the sole in the sense of crushing it, particularly when loading occurs body through the heel and over the heel area of the floor.
Podría parecer que la solución evidente a este problema es utilizar una suela de un material blando, elásticamente deformable, capaz de absorber los citados sobre-esfuerzos que se producen puntualmente al andar, pero en la práctica esto no es factible ya que la utilización de un material blando trae consigo un rápido deterioro de la suela y, en consecuencia, un considerable acortamiento de la vida útil del calzado.It might seem that the obvious solution to this problem is to use a soft material sole, elastically deformable, capable of absorbing the aforementioned over-efforts that occur promptly at walking, but in practice this is not feasible since the use of a soft material brings with it a rapid deterioration of the sole and, consequently, a considerable shortening of the useful life of the footwear.
El piso para calzado que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, haciendo que el calzado en su conjunto ofrezca unas prestaciones óptimas en cualquiera de los aspectos citados.The floor for footwear that the invention proposes solves the problem fully satisfactorily previously exposed, making the footwear as a whole offer optimal performance in any aspect cited.
Para ello y de forma mas concreta se ha previsto que dicho piso esté estructurado mediante tres piezas superpuestas, una suela que cuenta a nivel de su planta con las características inherentes a los Modelos de Utilidad con números de solicitud 200400736 y 200400737 (PCT ES05000018), de cualquier material elastomérico adecuado para ofrecer a la vez que una deformabilidad elástica aceptable, una barrera al desgaste adecuada para una larga vida útil, una plantilla destinada a superponerse a la citada suela y de un material también elastomérico pero muchísimo mas blando y elásticamente deformable, y una palmilla superior que a nivel de la planta es elásticamente deformable, como se verá mas adelante, con excepción del enfranque y el tacón donde es rígida, preferentemente obtenida a base de plástico rígido.For this and more specifically, it is planned that said floor is structured by three overlapping pieces, a sole that has the characteristics of its plant inherent to Utility Models with application numbers 200400736 and 200400737 (PCT ES05000018), of any material Elastomeric suitable to offer at the same time that a deformability acceptable elastic, a wear barrier suitable for long shelf life, a template designed to overlap the aforementioned sole and of an elastomeric material but much softer and elastically deformable, and an upper palm than at the level of the plant is elastically deformable, as will be seen later, with except for the heel and the heel where it is rigid, preferably obtained based on rigid plastic.
De acuerdo con otra de las características de la invención, la suela presenta unas características formales sobre su cara superior adecuadas para que encaje machihembradamente en la misma la complementaria plantilla, que a nivel de la planta se fija a la suela mediante un acoplamiento machihembrado de perfil en cola de milano, mientras que a nivel del enfranque y del tacón sobresale sustancialmente en sentido ascendente ofreciendo un espesor considerablemente mas grande, por cuanto que es esta zona posterior la que ha de recibir los esfuerzos puntuales mas acusados.According to another of the characteristics of the invention, the sole has formal characteristics on its upper face suitable to fit tongue and groove in the same the complementary template, which at the plant level is fixed to the sole by means of a tongue and groove coupling in glue profile of dove, while at the level of the chill and the heel protrudes substantially upwards offering a thickness considerably larger, because it is this posterior area which has to receive the most pronounced punctual efforts.
De esta manera la plantilla, que es la que confiere al piso el alto grado de deformabilidad elástica que ofrece frente a esfuerzos verticales generados a través del talón, queda totalmente independizada del suelo por la suela inferior, evitando problemas de desgaste, y repartiéndose uniformemente la carga sobre toda dicha zona a través del sector posterior y rígido de la palmilla, sector rígido que además está afectado por pequeños orificios para facilitar el paso de aire a su través y, en consecuencia, facilitar la transpiración del pie.In this way the template, which is what gives the floor the high degree of elastic deformability it offers against vertical efforts generated through the heel, it is completely independent of the ground by the bottom sole, avoiding wear problems, and evenly distributing the load on all said area through the back and rigid sector of the palmilla, rigid sector that is also affected by small holes to facilitate the passage of air through it and, in Consequently, facilitate foot perspiration.
La zona anterior de la palmilla, la correspondiente a la planta, para conseguir la deformabilidad requerida en sentido transversal, está constituida a partir de un cuerpo laminar afectado por una amplia ventana, ocupada por una pieza elástica, que es la que permite las deformaciones.The anterior area of the palm, the corresponding to the plant, to achieve deformability required in a transverse direction, it is constituted from a laminar body affected by a wide window, occupied by a elastic piece, which is what allows deformations.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

A la vista de las figuras reseñadas y en particular de la figura 1, puede observarse como en el piso para calzado que la invención propone participan tres piezas, una suela (1), una plantilla (2) y una palmilla (3).In view of the figures outlined and in particular of figure 1, can be seen as on the floor for footwear that the invention proposes involved three pieces, a sole (1), a template (2) and a palm (3).
La suela (1), obtenida mediante moldeo por inyección a partir de un material elastomérico apropiado, que combine elasticidad con resistencia al desgaste, incorpora como en la Patente de Invención repetidamente citada una serie de ranuras (4) a nivel de la zona de la planta, que se complementan con otras ranuras de su cara externa, desfasadas con respecto a las anteriores, en orden a permitir una deformación tipo "fuelle" cuando recibe una carga importante, y consecuentemente en orden a permitir un ensanchamiento del calzado a nivel de la planta, que a su vez permita el ensanchamiento del pie cuando recibe mayoritariamente la carga corporal del usuario.The sole (1), obtained by molding by injection from an appropriate elastomeric material, which combine elasticity with wear resistance, incorporates as in Invention Patent repeatedly cited a series of slots (4) at the level of the plant area, which are complemented by others grooves of its outer face, out of phase with respect to above, in order to allow a "bellows" type deformation when it receives a significant load, and consequently in order to allow a widening of footwear at the plant level, which to in turn allow foot widening when receiving mostly the user's body load.
De acuerdo ya con la invención, la citada suela (1) incorpora también a nivel de la planta, un grueso nervio perimetral (5) que define inmediatamente por debajo del mismo una ranura (6), convergente hacia la arista de dicho nervio (5) determinante de un acoplamiento en cola de milano para la plantilla (2), que queda así inmovilizada a la suela (1) por simple machihembrado, mientras que la porción posterior de dicha plantilla (2) descansa simplemente sobre la zona posterior de la suela (1), concretamente en una especie de cazoleta que define el borde libre y sobre-elevado (7) de dicha zona de la suela.In accordance with the invention, said sole (1) also incorporates a thick nerve at the plant level perimeter (5) that defines immediately below it a groove (6), convergent towards the edge of said nerve (5) determinant of a dovetail coupling for the template (2), which is thus immobilized to the sole (1) by simple tongue and groove, while the back portion of said template (2) rest simply on the back of the sole (1), specifically in a kind of bowl that defines the free edge and over-raised (7) of said sole area.
La plantilla (2), por su parte, presenta un borde biselado a nivel de la planta, para su acoplamiento machihembrado a la ranura (6) de la suela, y en su zona posterior presenta una superficie externa formal y dimensionalmente adecuada para encajar ajustadamente sobre el rehundido de la suela, siendo dicha plantilla (2) de un material considerablemente blando, que resulta fácilmente deformable elásticamente, viéndose potenciada esta deformabilidad por la existencia en dicha plantilla de un vaciado (8) sensiblemente centrado sobre la zona del talón.The template (2), meanwhile, presents a beveled edge at plant level, for coupling tongue and groove to the groove (6) of the sole, and in its posterior area it has a formal and dimensionally adequate external surface to fit tightly over the recess of the sole, being said template (2) of a substantially soft material, which It is easily elastically deformable, being enhanced this deformability due to the existence in said template of a emptying (8) substantially centered on the heel area.
El piso se complementa con la palmilla (3), cuya zona posterior (9), la correspondiente al enfranque y el tacón, es de un material rígido, preferentemente de plástico rígido, de manera que los esfuerzos debidos a la carga corporal del usuario sobre esta zona se reparten homogéneamente sobre la zona posterior de la plantilla (2) y consecuentemente sobre la zona posterior también de la suela (1), la correspondiente al tacón y al enfranque.The floor is complemented by palmilla (3), whose back area (9), the one corresponding to chilling and heel, is of a rigid material, preferably rigid plastic, so that the efforts due to the user's body load on this area are distributed homogeneously over the rear area of the template (2) and consequently on the back area also of the sole (1), the one corresponding to the heel and the boot.
Por el contrario el sector de la palmilla (3) correspondiente a la planta, es de un material flexible (10) y está afectada mayoritariamente por una ventana (11), ocupada por una lámina textil y elástica (12), que confiere a la palmilla la necesaria elasticidad y posibilidad de deformación elástica en sentido transversal, cuando lo hace el sector anterior de la suela (1), estando unida dicha lámina textil (12) a través de su perímetro a la pieza (10) con la colaboración de una costura (13).On the contrary the palmilla sector (3) corresponding to the plant, it is of a flexible material (10) and is mostly affected by a window (11), occupied by a textile and elastic sheet (12), which gives the palmilla the necessary elasticity and possibility of elastic deformation in transversal sense, when the previous sector of the sole does (1), said textile sheet (12) being joined through its perimeter to the piece (10) with the collaboration of a seam (13).
Solo resta señalar por último que, al objeto de hacer extensivo el confort del piso también al aspecto de aireación del pie, la pieza rígida (9) que participa en la palmilla (3) está afectada por una pluralidad de pequeños orificios circulares (14) que permiten el paso del aire a su través.It only remains to note finally that, in order to extend the comfort of the floor also to the aspect of aeration of the foot, the rigid piece (9) that participates in the palm (3) is affected by a plurality of small circular holes (14) that allow the passage of air through it.
