Description

PROCEDIMIENTO DE OBTENCIÓN DE UNA PLANTILLA Y PRODUCTO ASÍ OBTENIDO  PROCEDURE FOR OBTAINING A TEMPLATE AND PRODUCT SO OBTAINED
Objeto de la invención La presente invención tiene como objeto el procedimiento de obtención de una plantilla y producto así obtenido, y cuya principal ventaja radica en el hecho de aumentar la superficie de apoyo del pie, disminuyendo la presión de la pisada y por consiguiente, la carga soportada por el pie. Antecedentes de la invención OBJECT OF THE INVENTION The present invention has as its object the method of obtaining a template and product thus obtained, and whose main advantage lies in the fact of increasing the support surface of the foot, decreasing the pressure of the tread and consequently, the load supported by the foot. Background of the invention
En la actualidad, son conocidos diversos medios o métodos para conseguir plantillas mediante móldeos o similares, los cuales pueden ser personalizables mediante diversas técnicas, pero implican un coste económico elevado asociado a dicha personalización, que además no implique un resultado final efectivo en cuanto a dichas prestaciones. At present, various means or methods for obtaining templates by means of moldings or the like are known, which can be customizable by various techniques, but imply a high economic cost associated with said customization, which also does not imply an effective final result in terms of said benefits.
Así por ejemplo, podemos citar la patente GB1080489 que describe varios métodos para el moldeo de espumas de polímeros y la manufactura de diversos artículos, como son plantillas para calzado. Dicho documento, divulga estructuras laminadas que consisten en una capa central de un material espumoso rodeada por capas exteriores de la espuma modificada con una resina termoplástica, que se unen al esqueleto central por calentamiento y compresión. Así, por ejemplo, para la obtención de una plantilla, se recubrió una capa de una espuma plástica con un tejido de nailon en sus superficies exteriores, y el conjunto se colocó en un molde de aluminio precalentado, se calentó a 360 F (180eC), sometiéndose a una presión de 10 toneladas (9, 6 bares) durante 90 segundos. Una vez enfriada, la pieza moldeada se troqueló. For example, we can cite the GB1080489 patent that describes various methods for molding polymer foams and the manufacture of various articles, such as shoe insoles. Said document discloses laminated structures consisting of a central layer of a foamy material surrounded by outer layers of the foam modified with a thermoplastic resin, which are joined to the central skeleton by heating and compression. Thus, for example, to obtain a template, a layer of a plastic foam was coated with a nylon fabric on its outer surfaces, and the assembly was placed in a preheated aluminum mold, heated to 360 F (180 e C), undergoing a pressure of 10 tons (9, 6 bars) for 90 seconds. Once cooled, the molded part was die cut.
Del mismo modo la patente WO9309930 describe un procedimiento para obtener un perfil tridimensional en la superficie exterior de un cuerpo, que comprende una capa termoplástica y una capa elástica formada por un material elastomérico, como licra, pudiendo comprender además una tercera capa unida a la termoplástica y constituida por un polipropileno no-tejido o nailon. Las tres capas se unen preferentemente para formar una lámina previamente al procedimiento de conformado de la capa termoplástica. El producto laminado se calienta para que la capa de espuma alcance una temperatura suficiente para ser termoconformado (alrededor de 200eC), y se coloca en una prensa y se somete a presión en un molde de aluminio durante aproximadamente un minuto, de forma que se obtenga una imagen tridimensional en el laminado. Mediante este procedimiento de moldeo por compresión/termoconformado pueden obtenerse diversos artículos, como suelas de zapato. La patente US 5282326 describe una plantilla para calzado removible que comprende tres capas que están moldeadas integralmente formando un único artículo. El documento divulga también un procedimiento para la preparación de dicho artículo, que puede llevarse a cabo mediante métodos convencionales, como el termoconformado o el moldeo por compresión, seguido por el troquelado del producto obtenido Similarly, WO9309930 describes a process for obtaining a three-dimensional profile on the outer surface of a body, which comprises a thermoplastic layer and an elastic layer formed by an elastomeric material, such as lycra, and can also comprise a third layer attached to the thermoplastic and constituted by a non-woven polypropylene or nylon. The three layers are preferably joined to form a sheet prior to the thermoplastic layer forming process. The laminated product is heated so that the foam layer reaches a temperature sufficient to be thermoformed (about 200 e C), and is placed in a press and pressed into a mold of aluminum for about a minute, so that a three-dimensional image is obtained in the laminate. Various articles, such as shoe soles, can be obtained by this compression molding / thermoforming process. US 5282326 discloses a removable footwear insole comprising three layers that are integrally molded into a single article. The document also discloses a process for the preparation of said article, which can be carried out by conventional methods, such as thermoforming or compression molding, followed by die cutting of the product obtained
Finalmente, el titular de la invención, también es titular de la patente española ES 2 523 496 describe un procedimiento de obtención de un artículo termoconformado, efectuándose el procedimiento en un molde de aluminio y utilizando en la conformación del artículo o producto final tres capas de distintos materiales que comprende las siguientes fases operativas: Finally, the owner of the invention also owns the Spanish patent ES 2 523 496 describes a method of obtaining a thermoformed article, the procedure being carried out in an aluminum mold and using three layers of the final article or product different materials comprising the following operational phases:
