La siguiente Patente de Invención, según se expresa en el enunciado de la presente memoria descriptiva, consiste en un dispositivo aislante para calzado, el cual es de utilidad para su incorporación en aquel calzado cuya fabricación se efectúa por cosido del corte a la plantilla de montaje, o directamente a la suela, de forma que el dispositivo aislante, se constituye por una tira perimetral, preferentemente de caucho termopiástico, que se fija por un proceso de inyección a la plantilla o suela formando así un conjunto unitario, y la cual queda adosada internamente al corte. INSULATING DEVICE FOR FOOTWEAR - OBJECT OF THE INVENTION. The following Patent of Invention, as expressed in the statement of the present specification, consists of an insulating device for footwear, which is useful for incorporation into footwear whose manufacture is made by sewing the cut to the mounting template , or directly to the sole, so that the insulating device is constituted by a perimeter strip, preferably of thermoplastic rubber, which is fixed by an injection process to the template or sole thus forming a unitary assembly, and which is attached internally to the cut.
El dispositivo aislante tiene por objeto aislar el interior del zapato para evitar que pase agua hacia el interior, agua que se filtra por ios orificios de cosido, por lo que dichos modelos de calzado no son los más apropiados en la época invernal, y especialmente en aquellas zonas en las que hay abundantes precipitaciones.The purpose of the insulating device is to insulate the inside of the shoe to prevent water from entering inside, water that seeps through the sewing holes, so that these footwear models are not the most appropriate in the winter season, and especially in winter those areas where there is abundant rainfall.
CAMPO DE APLICACIÓN. El dispositivo aislante para calzado que se describe, es de aplicación en aquellos calzado conocidos como de tipo "cerrado", en los que el corte se une a la plantilla de montaje o directamente a la suela, por cosido. ANTECEDENTES DE LA INVENCIÓN.SCOPE. The insulating device for footwear described, is applicable in those footwear known as "closed" type, in which the cut joins the mounting template or directly to the sole, by sewing. BACKGROUND OF THE INVENTION
En el mercado, existe una gran diversidad de tipos de calzado, estando destinados determinados tipos para las distintas épocas del año, ya que los modelos utilizados en la época estival suelen presentar considerables diferencias con los modelos utilizados en la época invernal. Por otra parte, la fabricación de calzado, puede realizarse de distintas formas y con distintos materiales, de manera que si nos basamos en el tipo de zapatos "cerrados", como diferencia básica en su fabricación, podemos distinguir los que se fabrican uniendo el corte a la plantilla por pegado, y los que se fabrican uniendo el corte a la plantilla o suela por cosido. En el tipo de calzado en el que el corte se une a la plantilla de montaje, o directamente a la suela por cosido, se presenta el inconveniente de que los días de lluvia el agua se filtra al interior del zapato, a través de los orificios de cosido, de forma que los mismos no son los más apropiados paraIn the market, there is a great diversity of types of footwear, with certain types destined for the different times of the year, since the models used in the summer season usually present considerable differences with the models used in the winter time. On the other hand, the manufacture of footwear can be done in different ways and with different materials, so that if we rely on the type of "closed" shoes, as a basic difference in their manufacture, we can distinguish those that are manufactured by joining the cut to the template by gluing, and those that are manufactured by joining the cut to the template or sole by sewing. In the type of footwear in which the cut joins the mounting template, or directly to the sole by sewing, the inconvenience arises that on rainy days the water seeps into the shoe, through the holes sewing, so that they are not the most appropriate for
HOJA DE SUSTITUCIÓN (REGLA 26) aquellas zonas geográficas en las que se presenten numerosos días de lluvia, aunque dicho calzado sea perfectamente idóneo para el resto de los dias secos.SUBSTITUTE SHEET (RULE 26) those geographical areas in which there are numerous rainy days, although such footwear is perfectly suitable for the rest of the dry days.
Para solventar este inconveniente se trata de aislar el interior del zapato para que el agua no llegue hasta el pié del usuario, utilizándose goretex que permite aislar el pie y a la vez permite la transpiración, pero dicha ejecución presenta el inconveniente de que el goretex es un material muy caro, y además cuesta mucho trabajo su colocación, así como el sellado de todas las costuras del mismo para que sea efectivo, ya que en caso contrario quedarán ranuras por las que podría filtrarse el agua perdiendo toda su eficacia.To solve this problem, it is about insulating the inside of the shoe so that the water does not reach the user's foot, using goretex that allows the foot to be isolated and at the same time allows perspiration, but this execution has the disadvantage that goretex is a very expensive material, and in addition it costs a lot of work its placement, as well as the sealing of all the seams of the same to be effective, since otherwise there will be slots through which the water could seep losing all its effectiveness.
Así, dicha solución hace que el coste de los zapatos que incorporan la misma sea muy alto, tanto por el valor del goretex en sí, como por la mano de obra necesaria en su montaje.Thus, this solution means that the cost of the shoes that incorporate it is very high, both for the value of the goretex itself, and for the labor required in its assembly.
DESCRIPCIÓN DE LA INVENCIÓN. En la presente memoria se presenta un dispositivo aislante para calzado, el cual es de especial aplicación en aquellos modelos de calzado en los que el corte se une por cosido a la plantilla de montaje, o a la suela directamente, de forma que el dispositivo aislante se basa en una tira preferentemente de caucho termoplástico, que queda unida solidaria y perimetralmente por un proceso de inyección a la plantilla o a la suela, formando un conjunto unitario.DESCRIPTION OF THE INVENTION This report presents an insulating device for footwear, which is of special application in those models of footwear in which the cut is sewn together by the mounting template, or the sole directly, so that the insulating device is It is based on a strip of thermoplastic rubber, which is joined jointly and perimetrically by an injection process to the template or the sole, forming a unit assembly.
Dicha tira aislante, quedará dispuesta en relación a la parte externa de la correspondiente horma, quedando el corte, en su montaje, adosado a ella por su parte extema, de manera que al efectuar el cosido del corte por la parte extema de dicha tira aislante, ésta actúa como un perfecto aislante impidiendo el paso del agua hacia el interior del zapato, actuando como un perfecto aislante del agua, con lo que se evita su filtración al interior.Said insulating strip will be arranged in relation to the external part of the corresponding last, the cut being, in its assembly, attached to it by its external part, so that when sewing the cut by the external part of said insulating strip , this acts as a perfect insulator preventing the passage of water into the shoe, acting as a perfect water insulator, which prevents its filtration inside.
Así, la citada tira aislante, queda en posición ortogonal a la plantilla de montaje o suela, teniendo una pequeña altura y la misma queda en proximidad al contorno perimetral de la correspondiente plantilla o suela, dejando una banda extrema sobre la que se efectuará el cosido del corte, es decir, quedando el mismo hacia la parte externa de la tira aislante, para que esta cumpla su objetivo con total fiabilidad y seguridad.Thus, said insulating strip is orthogonal to the mounting template or sole, having a small height and it is in proximity to the perimeter contour of the corresponding template or sole, leaving an extreme band on which the sewing will be carried out of the cut, that is, being the same towards the outside of the insulating strip, so that it meets its objective with total reliability and safety.
HOJA DE SUSTITUCIÓN (REGLA 26) Con ello, obtenemos un calzado, del tipo de los que el corte se une por cosido, a la plantilla de montaje o a la suela directamente, cuyo interior queda perfectamente aislado, con total fiabilidad, a un bajo coste, de forma que la citada tira, dadas sus pequeñas dimensiones, conforma un conjunto unitario, sin presentar el mínimo problema a los usuarios, en el uso de los zapatos que lo incorporan.SUBSTITUTE SHEET (RULE 26) With this, we obtain a shoe, of the type of which the cut is joined by sewing, to the mounting template or to the sole directly, whose interior is perfectly isolated, with total reliability, at a low cost, so that the said strip , given its small dimensions, it forms a unit set, without presenting the minimum problem to the users, in the use of the shoes that incorporate it.
Para complementar la descripción que seguidamente se va a realizar, y con objeto de ayudar a una mejor comprensión de sus características, se acompaña a la presente memoria descriptiva, de un plano, en cuyas figuras, de forma ilustrativa y no limitativa, se representan los detalles más significativos de la invención, descrita en la presente memoria. BREVE DESCRIPCIÓN DE LOS DISEÑOS. Figura 1. Muestra una vista en planta de una plantilla de montaje, provista del dispositivo aislante definido por un resalte perimetral solidarizado a la misma, por cuya cara exterior se coloca el corte.To complement the description that will then be made, and in order to help a better understanding of its characteristics, the present descriptive report is accompanied by a plan, in whose figures, in an illustrative and non-limiting manner, the more significant details of the invention, described herein. BRIEF DESCRIPTION OF THE DESIGNS. Figure 1. It shows a plan view of a mounting template, provided with the insulating device defined by a perimetral shoulder in solidarity with it, on whose outer face the cut is placed.
Figura 2. Muestra una vista seccionada de la plantilla de montaje de la figura anterior, por el eje I-I, observando el resalte perimetral que actúa de elemento aislante, que queda solidarizado a la plantilla y por cuya cara externa se adosa al corte para su cosido a la plantilla en relación a la banda externa perimetral.Figure 2. It shows a sectional view of the mounting template of the previous figure, along the axis II, observing the perimeter projection that acts as an insulating element, which is in solidarity with the template and whose external face is attached to the cut for sewing to the template in relation to the outer perimeter band.
DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTE.DESCRIPTION OF A PREFERRED EMBODIMENT.
A la vista de las comentadas figuras y de acuerdo con la numeración adoptada, podemos observar como la plantilla de montaje o suela 1 , dispone perimetralmente en proximidad a su contorno un resalte o tira 2 ortogonal que se solidariza por un proceso de inyección a la propia plantilla o suela, siendo dicho resalte preferentemente de caucho termoplástico.In view of the aforementioned figures and in accordance with the numbering adopted, we can see how the mounting template or sole 1, has an orthogonal projection or strip 2 perimeter in proximity to its contour that is supported by an injection process to the own Insole or sole, said projection being preferably made of thermoplastic rubber.
De esta forma, el resalte o tira 2 perimetral define una banda 3 externa, de pequeña anchura en relación a la cual se materializa la unión del corte por cosido quedando el mismo en relación a la cara externa del citado resalte 2 a modo de tira.In this way, the edge or strip 2 defines an outer band 3 of small width in relation to which the joint of the cut by sewing materializes, being the same in relation to the external face of the said shoulder 2 as a strip.
Así, el resalte o tira 2 de pequeña altura y grosor, actúa como un elemento aislante del agua, con una total fiabilidad y además no representa la más mínima molestia al usuario en el uso normal habitual del calzado.Thus, the projection or strip 2 of small height and thickness, acts as an insulating element of water, with total reliability and also does not represent the slightest discomfort to the user in the normal normal use of footwear.
HOJA DE SUSTITUCIÓN (REGLA 26) La configuración de una plantilla de montaje o suela con un resalte o tira 2, preferentemente de caucho termoplástico, solidarizado por un proceso de inyección, será de especial aplicación en aquellos calzados del tipo cerrado en los que el corte 4 se une a la plantilla de montaje o a la suela directamente por cosido, de manera que de esta forma se logra aislar el interior del zapato con una total fiabilidad, por lo que dicho tipo de calzado podrá ser utilizado en día de lluvia sin que el agua pueda penetrar por ios orificios del cosido de unión del corte con la plantilla o suela, al interior del zapato, con lo que el pie del usuario queda perfectamente aislado. Con esta constitución de una forma sencilla y económica, se resuelve el grave inconveniente que presentan los calzados del tipo descrito, ya que al ser usados normalmente por los orificios de cosido del corte con la plantilla o suela, el agua se va filtrando hacia el interior, por lo que dicho calzado queda restringido para ser usado en días no lluviosos por lo que les hace de poco interés, en todas aquellas regiones que tienen lluvias con relativa frecuencia.SUBSTITUTE SHEET (RULE 26) The configuration of a mounting template or sole with a shoulder or strip 2, preferably of thermoplastic rubber, supported by an injection process, will be of special application in those footwear of the closed type in which the cut 4 joins the template of assembly or to the sole directly by sewing, so that in this way it is possible to insulate the inside of the shoe with total reliability, so that this type of footwear can be used on a rainy day without the water can penetrate through the holes of the sewn of union of the cut with the insole or sole, inside the shoe, so that the user's foot is perfectly isolated. With this constitution in a simple and economical way, the serious inconvenience of footwear of the type described is resolved, since when normally used by the sewing holes of the cut with the template or sole, the water is filtered inwards , so that such footwear is restricted to be used on non-rainy days, so it makes them of little interest, in all those regions that have rains with relative frequency.
