SUELA DE CALZADO CON PISO INTERCAMBIABLE FOOTWEAR SOLE WITH INTERCHANGEABLE FLOOR
D E S C R I P C I Ó N DESCRIPTION
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a una suela de calzado con piso intercambiable aportando, a la función a que se destina, ventajas y características, que se describen en detalle más adelante. The invention, as expressed in the title of the present specification, refers to a shoe sole with an interchangeable sole providing, to the function for which it is intended, advantages and characteristics, which are described in detail later.
Más concretamente, el objeto de la invención se centra en una suela de calzado que presenta la particularidad de comprender una parte superior fija y otra inferior intercambiable para poder cambiar el piso de la misma, ya sea para usar un tipo u otro de superficie, para modificar su altura, para ponerla nueva cuando se ha desgastado, para adaptarla a necesidades físicas por problemas de dismetría o, simplemente, para cambiar su aspecto, pudiendo, opcionalmente, comprender además una pieza intermedia para incrementar en mayor medida la altura de la suela. More specifically, the object of the invention focuses on a shoe sole that has the particularity of comprising a fixed upper part and an interchangeable lower part to be able to change the sole of the same, either to use one type or another of surface, to modify its height, to put it on again when it has been worn, to adapt it to physical needs due to dysmetria problems or, simply, to change its appearance, and may, optionally, also include an intermediate piece to further increase the height of the sole.
CAMPO DE APLICACIÓN DE LA INVENCIÓN FIELD OF APPLICATION OF THE INVENTION
El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de calzado, centrándose particularmente en el ámbito de las suelas para calzado. The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of footwear, focusing particularly on the field of soles for footwear.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Como es sabido existen muchos tipos de calzado con distintos tipos de suela que, a su vez, presentan diferentes tipos de piso, estando cada uno diseñado para un tipo de calzado y uso u otro. Sin embargo, hasta ahora, la suela del calzado es una parte fija e inseparable del propio calzado. As is known, there are many types of footwear with different types of soles that, in turn, have different types of soles, each one designed for one type of footwear and use or another. However, until now, the shoe sole is a fixed and inseparable part of the shoe itself.
Así, por ejemplo, en el caso del calzado deportivo, existen diferentes tipos de suelas con distintos tipos de piso, en función del uso o tipo de deporte para el que esté destinado. Por ejemplo, el piso de la suela de una zapatilla deportiva diseñada para correr o a hacer “running” tiene mucho más relieve, para propiciar el agarre, que el piso de la suela de una zapatilla destinada a caminar, que tendrá menos relieve. De modo similar, el piso de la suela de una zapatilla deportiva diseñada para jugar a tenis sobre tierra batida es mucho más liso que el piso de la suela de una zapatilla diseñada para jugar al tenis “quick” o de superficie cemento, que tiene mucho más relieve. Thus, for example, in the case of sports shoes, there are different types of soles with different types of soles, depending on the use or type of sport for which it is intended. For example, the bottom of the sole of a sports shoe designed for running or jogging has much more relief, to promote grip, than the bottom of the sole of a sports shoe. shoe intended for walking, which will have less relief. Similarly, the sole floor of a tennis shoe designed for playing tennis on clay courts is much smoother than the sole floor of a shoe designed for quick tennis or hard court tennis, which has much smoother surface. more relief.
En otras ocasiones, ocurre que, para uso diario es más práctico un calzado con poca suela, ya que es más cómodo si hay que trabajar o andar mucho, pero para salir o ir de fiesta puede ser más estético contar con una suela de plataforma elevada. On other occasions, it happens that, for daily use, a shoe with a small sole is more practical, since it is more comfortable if you have to work or walk a lot, but to go out or party it may be more aesthetic to have a raised platform sole. .
En tales casos, al igual que en otros muchos, sería ventajoso que, en lugar de tener que disponer de un tipo de calzado completo distinto para cada tipo de actividad, se pudiera contar con un único tipo de calzado y se pudiera cambiar solamente el tipo de piso de la suela, según se desee para una ocasión y otra y mantener el resto del calzado sin cambiar. In such cases, as in many others, it would be advantageous if, instead of having to have a completely different type of footwear for each type of activity, there could be only one type of footwear and only the type could be changed. of sole floor, as desired for one occasion and another and keep the rest of the shoe unchanged.
El objetivo de la presente invención es, pues, proporcionar al mercado un nuevo tipo de suela para calzado que permite dar respuesta a dicha problemática. The objective of the present invention is, therefore, to provide the market with a new type of sole for footwear that allows a response to said problem.
Por otra parte, y en referencia al estado actual de la técnica, cabe señalar que, al menos por parte del solicitante, se desconoce la existencia de ninguna otra suela de calzado con piso intercambiable, o invención similar que presente unas características técnicas y estructurales ¡guales o semejantes a las que presenta la suela que aquí se reivindica. On the other hand, and in reference to the current state of the art, it should be noted that, at least by the applicant, the existence of any other shoe sole with an interchangeable sole, or similar invention that has technical and structural characteristics, is unknown! equal or similar to those presented by the sole claimed here.
EXPLICACIÓN DE LA INVENCIÓN EXPLANATION OF THE INVENTION
La suela de calzado con piso intercambiable que la invención propone, permite alcanzar satisfactoriamente los objetivos anteriormente señalados, estando los detalles caracterizadores que lo hacen posible y que la distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción. The shoe sole with an interchangeable sole that the invention proposes allows the aforementioned objectives to be satisfactorily achieved, the characterizing details that make it possible and that conveniently distinguish it being collected in the final claims that accompany this description.
Lo que la invención propone, tal como se ha apuntado anteriormente, es una suela de calzado que se distingue por estar dividida en dos o más partes, comprendiendo, esencialmente, al menos, una parte superior que va fija al cuerpo del calzado y una parte inferior, cuya cara inferior determina el piso de la suela, es decir, la superficie que queda en contacto con el suelo, que es de carácter intercambiable gracias a que se acopla de manera extraíble a la parte fija, permitiendo ventajosamente cambiarla por otra u otras distintas, con diferentes objetivos. What the invention proposes, as noted above, is a shoe sole that is distinguished by being divided into two or more parts, essentially comprising, at least, an upper part that is fixed to the body of the shoe and a part lower, whose lower face determines the floor of the sole, that is, the surface that remains in contact with the ground, which is interchangeable thanks to the fact that it is attached in a removable way to the fixed part, advantageously allowing it to be changed for another or others. different, with different goals.
En concreto, el hecho de que la parte inferior de la suela de la invención sea intercambiable permite: Specifically, the fact that the lower part of the sole of the invention is interchangeable allows:
- poder cambiar el tipo y/o estructura del piso, por ejemplo uno liso por uno con relieve acentuado, para usar un tipo u otro de superficie según se desee para realizar un tipo u otro de actividad, - to be able to change the type and/or structure of the floor, for example a smooth one for one with accentuated relief, to use one type or another of surface as desired to carry out one type or another of activity,
- para modificar la altura de la suela y, consecuentemente, la altura del calzado, cambiando una pieza inferior poco gruesa o por otra más gruesa o viceversa, - to modify the height of the sole and, consequently, the height of the shoe, changing a lower piece that is not very thick or for a thicker one or vice versa,
- para poner una pieza nueva cuando se ha desgastado el piso por el uso, - to put a new piece when the floor has been worn by use,
- para adaptarla a necesidades físicas por problemas de dismetría, - to adapt it to physical needs due to dysmetria problems,
- o para cambiar su aspecto, permitiendo cambiarla de color, de textura, y/o de material. - or to change its appearance, allowing it to be changed in color, texture, and/or material.
Para ello, y más específicamente, la parte superior fija y la parte inferior intercambiable se unen entre sí mediante sistema de acople mecánico por machihembrado de la cara inferior de la parte superior fija con la cara superior de la parte inferior intercambiable. For this, and more specifically, the upper fixed part and the lower interchangeable part are joined together by means of a mechanical coupling system by dovetailing the lower face of the upper fixed part with the upper face of the lower interchangeable part.
En una forma de realización, dicho sistema de acople está conformado por una pluralidad de canales transversales, y resaltes complementarios, de configuración con sección en forma de cola de milano, en que, como es conocido por el experto, son más anchos en la parte distal que en el cuello, de manera que la parte inferior solamente se puede introducir de forma lateral para su acople a la parte superior deslizando los salientes de la parte inferior por los canales creados para su sujeción en la cara inferior de la parte superior. In one embodiment, said coupling system is made up of a plurality of transverse channels, and complementary projections, with a dovetail-shaped section configuration, in which, as is known to the expert, they are wider in the lower part. distal than in the neck, so that the lower part can only be inserted laterally for coupling to the upper part by sliding the projections of the lower part through the channels created for its fastening on the lower face of the upper part.
Además, opcionalmente dicho sistema de acople comprende además un canal, y correspondiente resalte, de acople adicional en la parte delantera (punta) y en la parte trasera (talón) de la suela, con una configuración en forma circular semejante a una “bombilla”, para dar mayor sujeción a dichas partes, al tratarse de las partes más vulnerables a la hora de la pisada. In addition, optionally, said coupling system also comprises a channel, and corresponding projection, for additional coupling in the front part (toe) and in the rear part (heel) of the sole, with a circular configuration similar to a "light bulb". , to give greater support to these parts, as they are the most vulnerable parts at the time of stepping.
Y, en otra opción de realización, dicho sistema de acople está conformado por una pluralidad de canales transversales, y resaltes complementarios, de configuración con sección en forma circular o de “bombilla”. Además, preferentemente, los laterales opuestos de cada una de las partes que comprende la suela presenta un tabique cerrado tal que, una vez acopladas dichas partes, los canales y resaltes del sistema de acople quedan ocultos y solo se aprecia una línea recta en la unión entre ambas partes. And, in another embodiment option, said coupling system is made up of a plurality of transverse channels, and complementary projections, with a circular or “bulb” shaped section configuration. In addition, preferably, the opposite sides of each of the parts that comprise the sole have a closed partition such that, once said parts are coupled, the channels and projections of the coupling system are hidden and only a straight line can be seen at the joint. between both parties.
Asimismo, en la realización preferida de la invención, se incluyen unos topes exteriores adicionales que encajan en unos orificios situados en correspondencia, para asegurar el acople entre ambas partes de la suela. Also, in the preferred embodiment of the invention, some additional outer stops are included that fit into holes located in correspondence, to ensure the coupling between both parts of the sole.
Finalmente cabe destacar que, en una vahante de realización, la suela comprende, además, una parte intermedia que asimismo se acopla de manera extraíble entre la parte superior fija y la parte inferior intercambiable de la suela, lo que permite incrementar la altura de la misma. Finally, it should be noted that, in a variant embodiment, the sole also comprises an intermediate part that is also removably coupled between the fixed upper part and the interchangeable lower part of the sole, which allows its height to be increased. .
Para ello, dicha parte intermedia cuenta con medios de acople en su cara superior y en su cara inferior que encajan complementariamente con los medios de acople de en la cara inferior de la parte superior fija y con los medios de la cara superior de la parte inferior intercambiable. For this, said intermediate part has coupling means on its upper face and on its lower face that complementarily fit with the coupling means on the lower face of the fixed upper part and with the means on the upper face of the lower part. interchangeable.
