Description

Método de fabricación de sandalias y molde para aplicación del mismo.Sandals and mold manufacturing method for application of it.

Object of the invention

La presente invención se refiere a un nuevo método de fabricación de sandalias, concretamente de sandalias conocidas en el argot con la denominación tipo "bio", estructuradas mediante un piso o suela de la que emergen lateralmente, como únicos elementos constitutivos del corte, sendas tiras, simples o múltiples, que se cierran sobre la zona del empeine por cualquier medio apropiado, como por ejemplo mediante hebillas.The present invention relates to a new sandals manufacturing method, specifically sandals known in slang with the "bio" type designation, structured by a floor or sole from which they emerge laterally, as the only constituent elements of the cut, paths strips, single or multiple, that close over the instep area by any appropriate means, such as through buckles

La invención concierne también al molde para la obtención de las sandalias con el método citado.The invention also concerns the mold for Obtaining sandals with the method mentioned.

Background of the invention

Como es sabido, las sandalias tipo "bio", están estructuradas a base de un piso de naturaleza apropiada, como por ejemplo de "EVA", caucho u otro, que puede ser monopieza o adoptar una estructura multicapa, con material de diferente naturaleza, y que a veces se cubre superiormente con una lámina constitutiva del melope, a base de piel, serraje o material similar.As is known, the "bio" sandals, they are structured based on a floor of an appropriate nature, such as for example of "EVA", rubber or other, which can be single piece or adopt a multilayer structure, with different material nature, and sometimes it is covered superiorly with a foil constituting the melope, based on leather, split or material Similary.

De forma más concreta a la pieza o piezas constitutivas del piso se fijan lateralmente las piezas o tiras constitutivas del corte, que en función del tipo de material utilizado para la obtención del piso se fijan mediante costuras laterales o mediante adhesivo.More specifically to the piece or pieces constitutive of the floor the pieces or strips are fixed laterally constitutive of the cut, which depending on the type of material used to obtain the floor are fixed by seams lateral or by adhesive.

Sea cual fuere la solución adoptada supone una notable participación de mano de obra con el consecuente encarecimiento de costos que ello trae consigo.Whatever the solution adopted is a remarkable participation of labor with the consequent higher costs that this entails.

Description of the invention

El método que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, y centra sus características en utilizar la propia fase o proceso de fabricación de la planta para conseguir la simultánea fijación a la misma del piso, la piel constitutiva del corte del calzado y el melope, de manera que la única operación complementaria que se requiere es la de fijar a dicho corte la hebilla o medio de cierre previsto para el mismo.The method proposed by the invention resolves the problem was fully satisfactory before exposed, and focuses its characteristics on using the phase itself or plant manufacturing process to achieve simultaneous fixing to it the floor, the skin constituting the cut of the footwear and melope, so that the only operation complementary that is required is to fix said cut the buckle or means of closure provided for it.

De forma más concreta y para la puesta en práctica del método de la invención se utiliza un molde, similar a los utilizados para la obtención de la planta de este tipo de calzado, generalmente de corcho, poliuretano, goma, esponja u otro material similar, con la particularidad de que dicho molde está debidamente sobredimensionado para introducir en el mismo, previamente a su cierre y al moldeo de la planta, la pieza constitutiva del piso, sobre la que estará convenientemente posicionada la pieza de piel, serraje o similar constitutiva del corte, mientras que el melope, en el caso de que exista, estará a su vez adaptado a la cara interna del contramolde, de manera que al cerrar el molde y efectuar la aportación del material constitutivo de la planta, éste actúa como nexo de unión para el resto de los elementos que participan en la sandalia, que sale así del molde prácticamente acabada, exclusivamente a falta de implantación en la misma, de la hebilla, hebillas o medios previstos para cierre del corte sobre el empeine del pie del usuario.More specifically and for putting in practice of the method of the invention a mold is used, similar to those used to obtain the plant of this type of footwear, usually cork, polyurethane, rubber, sponge or other similar material, with the particularity that said mold is duly oversized to enter in it, before closing and molding the plant, the piece constitutive of the floor, on which it will be conveniently positioned the piece of leather, split or similar constitutive of the cut, while the melope, if it exists, will be at in turn adapted to the internal face of the counter mold, so that at close the mold and make the contribution of the constituent material of the plant, this acts as a link for the rest of the elements that participate in the sandal, which thus leaves the mold practically finished, exclusively in the absence of implementation in the same, of the buckle, buckles or means provided for closing the cut on the instep of the user's foot.

De acuerdo con lo anteriormente expuesto el molde está estructurado mediante las tres piezas clásicas, un cuerpo base, un anillo intermedio y una tapa o contramolde, esta última preferentemente con la clásica configuración anatómica prevista para la cara superior de piso, con la especial particularidad de que el cuerpo base incorpora un rehundido formal y dimensionalmente coincidente con el piso propiamente dicho, es decir con la pieza de caucho o similar, para albergar a este último, y de que en la cara inferior del anillo intermedio se establecerán a su vez rebajes laterales para paso de las zonas asimismo laterales de la tira constitutiva del corte, que sobresalen del piso, de manera que dicha tira no impida el cierre del molde y además asegure la estanqueidad del mismo en situación de cierre.In accordance with the above, the mold is structured by the three classic pieces, a base body, an intermediate ring and a lid or counter mold, this last preferably with the classic anatomical configuration provided for the upper floor face, with the special particularity that the base body incorporates a formal recess and dimensionally coincident with the floor itself, it is say with the piece of rubber or similar, to house this last, and that on the underside of the intermediate ring is they will establish in turn lateral recesses for passage of the zones also sides of the strip constituting the cut, which protrude from the floor, so that said strip does not prevent the closure of the mold and also ensure the tightness of the same in situation of closing.

Preferred Embodiment of the Invention

A la vista de las figuras reseñadas puede observarse como en el molde para la puesta en práctica del método de la invención participan tres piezas, un cuerpo base (1), un anillo intermedio (2) y una tapa (3), unidas entre sí mediante una bisagra (4) común a todas ellas y provistas de empuñaduras o asideros (5) para facilitar las maniobras de apertura y cierre del molde, con la especial particularidad de que la pieza base (1) incorpora un rehundido (6), formal y dimensionalmente coincidente con la pieza (7) constitutiva del piso propiamente dicho, previamente obtenida a base de caucho, EVA, TR, PU, PVC, etc. de manera que tras la implantación de dicho piso propiamente dicho (7) el cuerpo base (1) ofrece una superficie plana y continua para asentamiento del anillo intermedio (2), el cual incorporará un orificio (8) que, con el conjunto constituido por el cuerpo base (1) y el piso propiamente dicho (7) por un lado, y la tapa (3) por otro, configura la cámara de moldeo para la planta (9), a base de corcho, poliuretano, goma, esponja o cualquier otro material apropiado.In view of the figures outlined you can be observed as in the mold for the implementation of the method Three pieces, a base body (1), a intermediate ring (2) and a cover (3), joined together by a hinge (4) common to all of them and provided with handles or handles (5) to facilitate the opening and closing maneuvers of the mold, with the special feature that the base piece (1) incorporates a recess (6), formally and dimensionally matching with the piece (7) constituting the floor itself, previously obtained based on rubber, EVA, TR, PU, PVC, etc. from so that after the implantation of said floor proper (7) the base body (1) offers a flat and continuous surface for intermediate ring settlement (2), which will incorporate a hole (8) which, with the assembly constituted by the base body (1) and the floor itself (7) on the one hand, and the cover (3) on another, configure the molding chamber for the plant (9), based on Cork, polyurethane, rubber, sponge or any other material appropriate.

En anillo intermedio (2) incorpora en su cara inferior y a ambos lados del orificio (7), sendos rebajes (10) (10'), formal y dimensionalmente adecuados para permitir la implantación en su seno de la tira (11) constitutiva del corte de la sandalia, pudiendo uno de estos rebajes (10') estar a su vez afectado, en su zona marginal externa, por otro rebaje (12) de mayor profundidad, para albergar las hebillas de la tira (11) constitutiva del cierre, en el supuesto de que dichas hebillas hayan sido montadas sobre la misma con anterioridad a la definitiva fabricación de la
sandalia.In the intermediate ring (2) it incorporates in its lower face and on both sides of the hole (7), two recesses (10) (10 '), formally and dimensionally suitable to allow implantation in its bosom of the strip (11) constituting the cut of the sandal, one of these recesses (10 ') being able to be affected, in its external marginal zone, by another recess (12) of greater depth, to house the buckles of the strip (11) constituting the closure, in the assumption that these buckles have been mounted on it prior to the final manufacture of the
sandal.

En cualquier caso la tira (11) debe ajustarse perfectamente el los rebajes (10) (10'), para rellenarlos completamente y establecer un perfecto cierre sobre la cara superior del cuerpo base (1).In any case the strip (11) must be adjusted perfectly the recesses (10) (10 '), to fill them completely and establish a perfect closure on the face upper body base (1).

Por lo demás la tapa o contramolde (3) incorporará una contrahuella (13) debidamente enfrentada a la ventana u orificio (8) del anillo intermedio para, además de cerrar la cámara definida en el seno de este último, dotar a la sandalia en su conjunto de cualquier configuración anatómica prevista para la misma, que será transferida también al melope (14) que se adapta a la cara interna de la tapa (3) antes de efectuar el cierre de la misma.Otherwise the cover or countermold (3) incorporate a riser (13) duly facing the window or hole (8) of the intermediate ring for, in addition to closing the chamber defined within the latter, provide the sandal as a whole any anatomical configuration intended for the same, which will also be transferred to the melope (14) that adapts to the inner face of the lid (3) before closing the same.

De acuerdo con esta estructuración y una vez ubicado el piso propiamente dicho (7) en el rehundido (6), adaptada la tira (11) a la cara inferior del anillo intermedio (2), perfectamente acoplada en los rebajes (10-10') de esta última, y adaptado el melope (14) a la cara inferior o interna de la tapa (3), bastará con cerrar un molde y rellenar la cámara (8) del material constitutivo de la planta (9) para que este actúe como nexo de unión entre todos los elementos integrantes de la sandalia, saliendo esta del molde prácticamente acabada, sin más necesidad que implantar sobre la tira (11) las complementarias hebillas, en el caso de que no hubieran sido montadas de antemano, y recortar el sobrante marginal (15) del melope (14).According to this structuring and once located the floor itself (7) in the recess (6), adapted the strip (11) to the underside of the intermediate ring (2), perfectly coupled in the recesses (10-10 ') of the latter, and adapted the melope (14) to the lower or inner face of the cover (3), just close a mold and fill the chamber (8) of the constituent material of the plant (9) so that it acts as a link between all the elements of the sandal, coming out of the mold practically finished, without more need to implant on the strip (11) the complementary ones buckles, in case they had not been mounted beforehand, and trim the marginal excess (15) of the melope (14).

Opcionalmente el piso propiamente dicho (7) puede ser obtenido simultáneamente a la planta (9) obviamente a expensas del mismo material, como por ejemplo utilizando poliuretano líquido, de manera que en este caso se repetirá el proceso descrito con la única salvedad de que el piso propiamente dicho (7) no se aloja en el rehundido (6), por cuanto que aún no está fabricado, y es el rehundido (6) el que dará lugar a la conformación del piso (7), paralelamente a la planta (9), cuando tras vertir el poliuretano líquido por la parte superior del molde, se produce la espumación del mismo en el seno de dicho molde, quedando la tira (11) embebida en el seno del bloque único de material constitutivo de piso y planta.Optionally the floor itself (7) it can be obtained simultaneously to the plant (9) obviously to at the expense of the same material, such as using liquid polyurethane, so that in this case the process described with the sole exception that the floor itself said (7) is not housed in the recess (6), because it has not yet It is manufactured, and it is the recess (6) that will give rise to the conformation of the floor (7), parallel to the floor (9), when after pouring the liquid polyurethane through the top of the mold, foaming thereof occurs within said mold, the strip (11) remaining embedded within the single block of constitutive floor and floor material.

Obviamente en este caso se puede utilizar exactamente el mismo cuerpo base (1) para el molde, cuando se pretenda obtener un piso con su cara inferior totalmente lisa, pero preferentemente dicho cuerpo base presentará el fondo de su rehundido (6) configurado de acuerdo con cualquier diseño previsto para la cara inferior del piso a obtener.Obviously in this case you can use exactly the same base body (1) for the mold, when pretend to get a flat with its underside completely smooth, but preferably said base body will present the bottom of its recessed (6) configured according to any intended design for the underside of the floor to obtain.
