El campo de aplicación de la presente invención se enmarca dentro del sector técnico de la industria dedicada a la fabricación de plantillas para pies abarcando a la vez la industria dedicada a la fabricación de zapatos, particularmente zapatos especiales.  The field of application of the present invention falls within the technical sector of the industry dedicated to the manufacture of foot insoles while covering the industry dedicated to the manufacture of shoes, particularly special shoes.
Antecedentes de la invención Background of the invention
En la actualidad, y como referencia al estado de la técnica, debe señalarse que, si bien son conocidos en el mercado múltiples tipos de plantillas, por parte del solicitante se desconoce la existencia de ninguna que presente unas características técnicas, estructurales y constitutivas semejantes a las que presenta la que aquí se preconiza, y cuyos detalles caracterizadores se encuentran convenientemente recogidos en las reivindicaciones finales que acompañan a la presente memoria descriptiva de la misma. Descripción de la invención At present, and as a reference to the state of the art, it should be noted that, although multiple types of templates are known in the market, the existence of none that presents technical, structural and constitutive characteristics similar to those of the applicant is unknown. those presented here, and whose characterizing details are conveniently included in the final claims that accompany the present specification thereof. Description of the invention
De forma concreta, lo que la invención propone, como ya se ha apuntado anteriormente, es una plantilla cuya configuración estructural está realizada a base de retículas, las cuales se diseñan con una geometría y disposición determinada en cada zona de la plantilla para adaptarse de forma precisa y personalizada a la geometría del pie del usuario, teniendo en cuenta, además, su peso y tipo de actividad y/o patología a corregir una personalización extremadamente precisa de la misma.  Specifically, what the invention proposes, as already noted above, is a template whose structural configuration is made of reticles, which are designed with a determined geometry and arrangement in each area of the template to adapt so precise and personalized to the geometry of the user's foot, taking into account, in addition, its weight and type of activity and / or pathology to correct an extremely precise customization of it.
Más concretamente, la plantilla de la invención comprende un cuerpo, realizado de una sola pieza y preferentemente obtenido por tecnología de sintetizado o fabricación aditiva mediante "impresión en 3D", con posibilidad de tratamiento/s posterior/es, pudiendo ser el tipo de material utilizado poliamidas, materiales metálicos como por ejemplo el titanio, o cualquier otro tipo de material susceptible de poder aplicar dichas tecnologías, y sin que se descarten otros materiales y/o procedimientos de fabricación, contando dicho cuerpo con la particularidad de comprender una superficie superior que contacta con el pie del usuario y una superficie inferior que contacta con la parte interior de la suela del zapato, sólidas o con perforaciones para facilitar la transpiración, unidas entre sí por un núcleo interno conformado a partir de retículas, entendiéndose dichas retículas como cavidades definidas por tabiques, barras, o combinación de ambas, que se extienden desde dicha envoltura externa hacia el interior, y que proporcionan, la posibilidad de circulación del aire a través de la plantilla además de otras ventajas, como una mayor ligereza, menor necesidad de material, un comportamiento mecánico más adecuado, etc. More specifically, the template of the invention comprises a body, made of a single piece and preferably obtained by synthesizing technology or additive manufacturing by "3D printing", with the possibility of subsequent treatment / s, which may be the type of material used polyamides, metallic materials such as titanium, or any other type of material capable of applying said technologies, and without discarding other materials and / or manufacturing procedures, said body having the particularity of comprising a superior surface that it contacts the user's foot and a lower surface that contacts the inner part of the sole of the shoe, solid or with perforations to facilitate perspiration, joined together by an inner core formed from reticles, said reticles being understood as defined cavities by partitions, bars, or combination of both, which extend from said env external inward groove, and that provide, the possibility of air circulation through the template in addition to other advantages, such as a greater lightness, less need for material, a more appropriate mechanical behavior, etc.
Además, según otra particularidad de la invención, dicho cuerpo conformante de la plantilla de la invención presenta una o más zonas en las que las citadas retículas son de inclinación, geometría, orientación, grosor y/o densidad variable y distinta respecto del resto del mismo, haciendo que tales zonas puedan contar con mayor o menor elasticidad, en función del grosor, geometría, orientación y disposición de las retículas, de tal modo que, por ejemplo, la configuración de dichas retículas sea tal que en la zona del talón la plantilla monopieza sirva para amortiguar y la orientación, geometría, grosor y posición de las retículas en la zona del arco plantar sirva para impulsar.  In addition, according to another feature of the invention, said body forming the template of the invention has one or more areas in which said reticles are of inclination, geometry, orientation, thickness and / or variable density and different from the rest thereof. , causing such areas to have greater or lesser elasticity, depending on the thickness, geometry, orientation and arrangement of the reticles, such that, for example, the configuration of said reticles is such that in the heel area the insole single piece serves to cushion and the orientation, geometry, thickness and position of the reticles in the area of the plantar arch serves to boost.
Por su parte, tales zonas vendrán determinadas, en su tamaño, forma y posición, en función de la geometría y/o de la patología a corregir del pie del usuario, en caso de haberla, así como del peso de dicho usuario y/o de la actividad a que se dedique o a que desee destinar la plantilla, pudiendo, por tanto, diseñarse estructuralmente de forma personalizada en cada caso para cada usuario. Asimismo, dichas retículas pueden seguir un patrón regular y basado en geometrías simples (como esferas u otros cuerpos geométricos regulares de distintos tipos), o irregular, así como una combinación de ambos. For their part, such areas will be determined, in their size, shape and position, depending on the geometry and / or pathology to be corrected of the user's foot, if any, as well as the weight of said user and / or of the activity to which it is dedicated or that it wishes to allocate the workforce, being able, therefore, to be structurally designed personalized form in each case for each user. Likewise, said reticles can follow a regular pattern based on simple geometries (such as spheres or other regular geometric bodies of different types), or irregular, as well as a combination of both.
Conviene destacar que, además de la forma externa de la plantilla, para poder determinar con precisión, la forma, tamaño y disposición de las descritas zonas variables de la misma según las citadas premisas, ésta se obtiene a partir de una imagen o modelo en tres dimensiones del pie del usuario captada con un escáner tridimensional. It should be noted that, in addition to the external shape of the template, to be able to determine precisely, the shape, size and arrangement of the described variable areas of the same according to the aforementioned premises, this is obtained from an image or model in three dimensions of the user's foot captured with a three-dimensional scanner.
Opcionalmente, sin embargo, la plantilla puede realizarse también a partir de un cuerpo formado por varias partes o módulos combinables, de forma que la estructura reticular interna pudiese ser intercambiable por piezas genéricas diseñadas para pacientes tipo, en función de varias geometrías concretas de pies, peso del paciente y de varias configuraciones reticulares distintas diseñadas para distintas actividades, pudiendo incluirse la suela, en lugar de a partir de un cuerpo monopieza, en orden a conseguir una plantilla generalizada, es decir, no personalizada mediante captación de imagen plantar por escáner 3D, sino que se compone de diferentes módulos (talón, arco plantar, puntera,...) unidos entre sí y cuya combinación permite realizar plantillas generalizadas para un usuario tipo. Optionally, however, the template can also be made from a body formed by several combinable parts or modules, so that the internal reticular structure could be interchangeable by generic pieces designed for type patients, depending on several concrete foot geometries, weight of the patient and several different reticular configurations designed for different activities, the sole being able to be included, instead of from a single piece body, in order to achieve a generalized template, that is, not personalized by means of plantar image capture by 3D scanner , but consists of different modules (heel, plantar arch, toe, ...) joined together and whose combination allows generalized templates for a type user.
Además, y también opcionalmente, el citado cuerpo conformante de la plantilla podrá incorporar una o más capas de material similar o distinto adosadas superior y/o inferiormente al mismo, por ejemplo una capa superior embellecedora o que mejore el tacto al pie, una capa intermedia para absorción de humedad o para mejorar la amortiguación, una capa inferior de refuerzo, etc. In addition, and also optionally, said template shaping body may incorporate one or more layers of similar or different material attached upper and / or lower thereto, for example a top layer embellishing or improving the touch at the foot, an intermediate layer for moisture absorption or to improve damping, a lower reinforcing layer, etc.
Con el fin de mejorar las propiedades de la plantilla, ésta podrá ser recubierta, pintada o impregnada utilizando aditivos que le confieran una mejora en ciertas propiedades, como rigidez, resistencia al desgaste, flexibilidad superficial, etc. In order to improve the properties of the template, it can be coated, painted or impregnated using additives that give it an improvement in certain properties, such as stiffness, wear resistance, surface flexibility, etc.
Por último, cabe destacar que la descrita plantilla tanto puede consistir en un elemento independiente que se incorpora en el interior del zapato como formar parte del mismo, en cuyo caso constituye una única pieza con la propia suela del zapato y, por tanto, no será extraíble, pero proporciona la ventaja de poder diseñar de forma personalizada tanto el apoyo interno (plantilla) como la suela del calzado. Finally, it should be noted that the described template can both consist of an independent element that is incorporated into the interior of the shoe and be part of it, in which case it constitutes a single piece with the sole of the shoe and, therefore, will not be Removable, but it provides the advantage of being able to custom design both the internal support (insole) and the sole of the footwear.
Dicha posibilidad no es tan solo una cuestión estética o de fabricación, sino que tiene una funcionalidad, ya que al ir en una sola pieza la plantilla reticular y la suela, la configuración de la plantilla trasmite los movimientos del pie del usuario a la suela de una forma más efectiva y eficiente que mediante el sistema tradicional de plantilla (no reticular) y suela independiente. En estos sistemas tradicionales entre el pie, la plantilla y la suela hay otros elementos-planilla, forro,... que distorsionan o como mínimo limitan la trasmisión de los movimientos del pie hasta la suela. This possibility is not only an aesthetic or manufacturing issue, but it has a functionality, since when the reticular template and the sole are in one piece, the configuration of the template transmits the movements of the user's foot to the sole of a more effective and efficient way than through the traditional template system (not cross-linked) and independent sole. In these traditional systems between the foot, the insole and the sole there are other elements-payroll, lining, ... that distort or at least limit the transmission of the movements of the foot to the sole.
Visto lo que antecede, se constata que la descrita plantilla de estructura reticular representa una estructura innovadora de características estructurales y constitutivas desconocidas hasta ahora en su campo de aplicación, razones que unidas a su utilidad práctica, la dotan de fundamento suficiente para obtener el privilegio de exclusividad que se solicita. In view of the above, it is found that the described reticular structure template represents an innovative structure of structural and constitutive characteristics unknown until now in its field of application, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity requested.
Descripción de los dibujos Description of the drawings
Para complementar la descripción que se está realizando de la plantilla objeto de la invención, y para ayudar a una mejor comprensión de las características que la distinguen, se acompaña la presente memoria descriptiva, como parte integrante de la misma, de un juego de planos, en los que con carácter ilustrativo y no limitativo se ha representado lo siguiente:  To complement the description that is being made of the template object of the invention, and to help a better understanding of the characteristics that distinguish it, the present descriptive report is attached, as an integral part thereof, of a set of drawings, in which the following has been represented by way of illustration and not limitation:
La figura número 1 .- Muestra una vista en perspectiva y sección longitudinal de la plantilla de estructura reticular objeto de la invención, en un ejemplo de realización de la misma basada en la repetición homogénea de cavidades con geometría simple apreciándose en ella su configuración general y las partes que la integran.  Figure number 1 .- Shows a perspective view and longitudinal section of the reticular structure template object of the invention, in an embodiment thereof based on the homogeneous repetition of cavities with simple geometry, showing its general configuration and the parts that integrate it.
La figura número 2.- Muestra una vista similar a la anterior de otro ejemplo de realización de la plantilla de la invención, en este caso en un ejemplo de la misma basada en la combinación de zonas con repetición homogénea de cavidades con geometría simple con distintos tamaños y zonas con cavidades de geometría irregular. La figura número 3.- Muestra otra vista en perspectiva y sección longitudinal de un tercer ejemplo de la platilla de la invención, en este caso formando una misma pieza con la suela del zapato,de forma que permita diseñarse en una única pieza tanto el apoyo interno como la suela del calzado. En este ejemplo se trata de una bota de fútbol de geometría totalmente personalizada (horma, colocación de los tacos, rugosidades, etc). De este modo se consigue no sólo la personalización de la plantilla sino la personalización en una única pieza del conjunto plantilla-suela.  Figure number 2.- Shows a view similar to the previous one of another embodiment of the template of the invention, in this case in an example thereof based on the combination of areas with homogeneous repetition of cavities with simple geometry with different sizes and zones with irregular geometry cavities. Figure number 3. - It shows another perspective view and longitudinal section of a third example of the plate of the invention, in this case forming the same piece with the sole of the shoe, so that it can be designed in a single piece both the support internal as the sole of footwear. In this example it is a football boot with a completely personalized geometry (last, placement of the studs, roughness, etc). In this way, not only the customization of the template is achieved, but also the customization in a single piece of the template-sole set.
Realización preferente de la invención Preferred Embodiment of the Invention
A la vista de la descrita figura 1 , y de acuerdo con la numeración adoptada en ella, se puede apreciar como la plantilla (1 ) en cuestión comprende un cuerpo (2), conformado por una superficie superior (3) que contacta con el pie del usuario, y una superficie inferior (3') que contacta con la parte interior del zapato, unidas entre sí por un núcleo interno (4) conformado a partir de retículas (5), en que tales retículas (5) conforman cavidades definidas por tabiques, barras, o combinación de ambas, que se extienden desde dicha envoltura externa (3) hacia el interior del cuerpo (2), permitiendo la circulación del aire a través de la plantilla (1 ). In view of the described figure 1, and according to the numbering adopted therein, it can be seen how the template (1) in question comprises a body (2), formed by an upper surface (3) that contacts the user's foot, and a lower surface (3 ') that contacts the inside of the shoe, joined together by an inner core (4) formed from reticles (5) , in which such reticles (5) form cavities defined by partitions, bars, or combination of both, which extend from said outer envelope (3) into the interior of the body (2), allowing air circulation through the template (one ).
Además, dicho núcleo interno (4) presenta una o más zonas (4') en las que las retículas (5) son de geometría, orientación, inclinación, disposición, grosor y/o densidad variable y distinta respecto del resto de cuerpo (2), con el fin de otorgar al mismo mayor o menor elasticidad en determinados puntos, según convenga en cada caso, en función de la geometría y/o patología del pie, y/o del peso o actividad de un usuario determinado, para lo cual la plantilla se obtiene, preferentemente a partir de una imagen en tres dimensiones del pie captada con un escáner tridimensional y el cuerpo (2) se realiza en una sola pieza, pudiendo, opcionalmente estar constituido a partir de diferentes partes (talón, arco plantar, puntera...) con zonas (4') distintas unidas entre sí, como muestra el ejemplo de la figura 2, para adaptarse a diferentes tipologías de usuarios, o bien ser de forma homogénea como muestra el ejemplo de la figura 1 .  In addition, said inner core (4) has one or more zones (4 ') in which the reticles (5) are of geometry, orientation, inclination, arrangement, thickness and / or variable and different density with respect to the rest of the body (2 ), in order to grant the same greater or lesser elasticity at certain points, as appropriate in each case, depending on the geometry and / or pathology of the foot, and / or the weight or activity of a particular user, for which The template is obtained, preferably from a three-dimensional image of the foot captured with a three-dimensional scanner and the body (2) is made in one piece, and may optionally be constituted from different parts (heel, plantar arch, toe ...) with different zones (4 ') joined together, as shown in the example of figure 2, to adapt to different types of users, or be homogeneous as shown in the example of figure 1.
Conviene señalar, además, que el cuerpo (2) conformante de la plantilla, y más concretamente la anteriormente citada superficie superior (3) del mismo, presenta una forma con geometría adaptada a la morfología del pie, mientras que la superficie inferior (3') bien puede presentar una forma plana (como la del ejemplo representado en las figuras 1 y 2) o bien una forma de geometría similar a la de la superficie superior (3), es decir, adaptada también a la morfología del pie.  It should also be noted that the body (2) forming the template, and more specifically the aforementioned upper surface (3) thereof, has a shape with geometry adapted to the morphology of the foot, while the lower surface (3 ' ) It can either have a flat shape (as in the example shown in Figures 1 and 2) or a shape similar to that of the upper surface (3), that is, also adapted to the morphology of the foot.
Asimismo, y también de forma opcional, el cuerpo (2) incorpora una o más capas adicionales (6), del mismo material u otro distinto, adosadas superior y/o inferiormente al mismo, y puede estar perforado para mejorar la transpiración. Likewise, and also optionally, the body (2) incorporates one or more additional layers (6), of the same or different material, attached superiorly and / or inferiorly thereto, and may be perforated to improve perspiration.
Por último, el cuerpo (2) conformante de la plantilla (1 ) es, como en los ejemplos de las figuras 1 y 2, un elemento independiente que se incorpora en el interior del zapato del usuario o, alternativamente, como muestra el ejemplo de la figura 3, forma una única pieza con la propia suela del zapato, tratándose preferentemente aunque no de forma limitativa de un calzado deportivo, para lo cual la superficie inferior (3') estará convenientemente regruesada, pudiendo presentar diferentes formas y grosores, según el tipo de calzado o las necesidades de cada caso. En este caso de calzado deportivo (botas de fútbol, de baloncesto, zapatillas de atletismo, etc.), para el que la integración del cuerpo (2) con la suela del zapato tiene especial interés, se podrá diseñar la suela en función de la peculiaridad del deporte y el usuario, añadiendo los distintos elementos que necesite, tales como tacos, estrías, etc, pudiendo estar dicha suela fabricada en una única pieza o bien mediante el ensamblado de piezas diferentes. Finally, the body (2) forming the template (1) is, as in the examples of figures 1 and 2, an independent element that is incorporated into the interior of the user's shoe or, alternatively, as the example of Figure 3, forms a single piece with the sole of the shoe, preferably though not limited to a sports shoe, for which the bottom surface (3 ') will be conveniently thickened, being able to present different shapes and thicknesses, according to the type of footwear or the needs of each case. In this case, sports shoes (football boots, basketball shoes, athletic shoes, etc.), for which the Integration of the body (2) with the sole of the shoe is of special interest, the sole can be designed based on the peculiarity of the sport and the user, adding the different elements that you need, such as heels, stretch marks, etc., being able to be said sole manufactured in a single piece or by assembling different pieces.
Esta realización de la plantilla (1 ) integrada con la suela del zapato evita el desplazamiento relativo de ambos elementos, lo que permite que la transmisión de esfuerzos desde el pie hasta el suelo se mejore sustancialmente, en contraposición a lo que se sucede en la actualidad, en la que la plantilla tradicional se coloca encima de la suela del zapato, existiendo desplazamiento relativo entre ambos elementos.  This embodiment of the insole (1) integrated with the sole of the shoe prevents the relative displacement of both elements, which allows the transmission of efforts from the foot to the ground to be substantially improved, as opposed to what is currently happening , in which the traditional insole is placed on top of the sole of the shoe, there being relative displacement between both elements.
