Elemento de sellado de orificiosHole sealing element
La presente invención se refiere a un elemento de sellado de orificios, por ejemplo, para su aplicación a chapas de carrocería de vehículos.The present invention relates to a hole sealing element, for example for application to vehicle body plates.
Antecedentes de la invenciónBackground of the Invention
Se conocen diversas formas de obturar orificios realizados en chapas de carrocería de vehículos o en otros componentes, y en tal sentido puede citarse en primer lugar el documento ES2006404.Various ways of closing holes made in vehicle body plates or other components are known, and in this sense, document ES2006404 can be mentioned first.
Este documento describe una tapa de cierre de plástico para cerrar una abertura de una carrocería de vehículos, estando basada en que la tapa incluye un labio perimetral de obturación en disposición inclinada y un anillo de enclavamiento elástico opuesto a dicho labio, de manera que este último apoya sobre la periferia del elemento o chapa en la que está realizado el orificio en el que precisamente se aloja la tapa, mientras que el anillo de enclavamiento se apoya en la cara inferior de dicha chapa o elemento de que se trate.This document describes a plastic closure cover to close an opening of a vehicle body, being based on the fact that the cover includes a perimeter sealing lip in an inclined arrangement and an elastic locking ring opposite to said lip, so that the latter it rests on the periphery of the element or sheet in which the hole in which the cover is precisely housed is made, while the interlocking ring rests on the underside of said sheet or item in question.
En este documento también se describe que, por debajo del anillo de enclavamiento, se ha previsto un apoyo susceptible de estar configurado por otro labio elástico, el cual presiona contra el anillo de enclavamiento para mantenerlo en contacto permanente sobre la superficie correspondiente al elemento o chapa en el que esté realizado el orificio que obtura la tapa, para conseguir una hermeticidad.In this document it is also described that, underneath the interlocking ring, a support capable of being configured by another elastic lip is provided, which presses against the interlocking ring to keep it in permanent contact on the surface corresponding to the element or sheet metal in which the hole that seals the cover is made, to achieve a tightness.
Aunque este tipo de cierres resulta sencillo, es evidente que la estanqueidad a veces no es la apropiada u óptima, debido a la deformación o incluso posible rotura tanto del elemento de apoyo como del anillo de enclavamiento.Although this type of closure is simple, it is evident that the sealing is sometimes not appropriate or optimal, due to deformation or even possible breakage of both the support element and the locking ring.
Para mejorar la estanqueidad, el documento ES2097565 describe otra tapa de cierre elástico en la que se incluye una junta deformable por calor, y unas patillas de anclaje de la tapa, aunque lógicamente la junta para que ofrezca una óptima estanqueidad es necesario que se caliente.To improve the sealing, document ES2097565 describes another elastic closing cover in which a heat deformable seal is included, and some anchor lugs for the cover, although logically, in order to offer an optimal seal, it must be heated.
Este documento también describe un obturador para sellar orificios en chapas, diseñado, en particular, para sellar orificios hechos en chapas, tales como las de carrocerías de automóviles, que comprende un cuerpo en forma de cazoleta con un ala exterior periférica divergente, derivada desde un cuello, formado por la forma en cazoleta del cuerpo y divergiendo hacia fuera desde dicho cuello, y un ala interior periférica divergente en el extremo de dicho cuello opuesto a dicha ala exterior.This document also describes a shutter for sealing holes in sheet metal, designed in Particularly for sealing holes made in sheets, such as those of automobile bodies, comprising a bowl-shaped body with a diverging peripheral outer wing, derived from a neck, formed by the bowl-shaped shape of the body and diverging outward from said neck, and a diverging peripheral inner wing at the end of said neck opposite to said outer wing.
En todos los casos, el problema que presentan los elementos de sellado citados anteriormente es que ninguno resulta aislante ni térmica ni acústicamente, además de que el enclavamiento resulta complejo, puesto que las alas deformables, patillas o arpones que incorporan en unos u otros casos, no ofrecen una óptima fiabilidad en su función, independientemente de resultar complejas.In all cases, the problem presented by the aforementioned sealing elements is that none is thermally or acoustically insulating, in addition to the interlocking being complex, since the deformable wings, pins or harpoons that incorporate in one or the other cases, they do not offer optimum reliability in their function, regardless of being complex.
Para intentar solucionar esos problemas, los documentos EP0631923A1 y EP0779203A1 describen sendos obturadores-selladores dotados de dos zonas o bandas de sellado a base de un material fundente o cola, al objeto de que en la aplicación del obturador-sellador sobre el orificio de la chapa correspondiente se produzca una primera zona de sellado, en correspondencia con el apoyo del labio perimetral y externo del cuerpo del obturador sobre la superficie superior de la chapa, con la interposición de la cola o material fundente y sellado.To try to solve these problems, documents EP0631923A1 and EP0779203A1 describe respective shutters-sealers provided with two zones or sealing bands based on a flux material or glue, in order to apply the shutter-sealer over the hole in the sheet metal Correspondingly, a first sealing zone is produced, corresponding to the support of the perimeter and external lip of the shutter body on the upper surface of the sheet, with the interposition of the glue or flux and sealed material.
Además, una segunda banda de obturación o sellado la constituye un anillo concéntrico y previsto en el cuello del propio obturador-sellador, de manera que en este caso el sellado se establece entre el contorno del orificio y ese cordón o banda fundible en forma de anillo situado sobre el cuello del obturador-sellador, estableciéndose así dos bandas de sellado y consiguiéndose con ello una mayor hermeticidad y un óptimo aislamiento entre las dos partes que se determinan a uno y otro lado del orificio obturado mediante el dispositivo referido.In addition, a second sealing or sealing band is made of a concentric ring and provided on the neck of the plug-sealer itself, so that in this case the seal is established between the contour of the hole and that fuse or ring-shaped fusible band located on the neck of the obturator-sealer, thus establishing two sealing bands and thereby achieving greater tightness and optimum insulation between the two parts that are determined on either side of the orifice sealed by means of the aforementioned device.
No obstante, el inconveniente que presentan las soluciones descritas en estos documentos consiste en que la cola o producto termofusible se encuentra dispuesto exteriormente al cuerpo o pieza constitutiva del obturador-sellador, lo que origina problemas a la hora de efectuar el montaje sobre el orificio correspondiente, ya que en la operación de corte para la obtención del orificio origina la correspondiente rebaba que va a establecer una primera zona de contacto en el momento de intentar aplicar o introducir el obturador-sellador sobre tal orificio, de manera que al ser el producto o cola termofusible de un material blando, al topar con la rebaba, va a quedar anclada por tal rebaba, lo que requiere tener que efectuar el montaje de una manera determinada y concreta, lo cual no siempre es posible de ejecutar.However, the drawback of the solutions described in these documents consists in that the glue or hot melt product is arranged externally to the body or component of the plug-sealant, which causes problems when mounting on the corresponding hole , since in the cutting operation to obtain the hole, the corresponding burr originates that will establish a first contact area when trying to apply or introduce the plug-sealer over said hole, so that as the product or hot melt glue of a soft material, when it meets the burr, will be anchored by such a burr, which requires having to carry out mounting in a certain and concrete way, which is not always possible to execute.
Para intentar solucionar este inconveniente, el documento EP1375308A1 describe un obturador-sellador que comprende un segundo anillo de sellado de material fundente en el interior del ala interna para aportar una correspondiente área de sellado en la superficie de la chapa, sobre la que se aplica, con el fin de permitir el montaje del obturador dentro del correspondiente orificio de la chapa, sin el contacto inicial entre el material blando de los anillos compuesto de material fundente y una rebaba que se forma cuando se taladra el orificio.To try to solve this drawback, document EP1375308A1 describes a shutter-sealer that comprises a second sealing ring of flux material inside the inner wing to provide a corresponding sealing area on the surface of the sheet, on which it is applied, in order to allow the mounting of the shutter inside the corresponding hole in the sheet metal, without the initial contact between the soft material of the rings composed of flux material and a burr that is formed when the hole is drilled.
Por lo tanto, un objetivo de la presente invención es proporcionar un elemento de sellado para orificios, en particular para orificios de chapas de carrocería de vehículos, evitando el uso de material fundente o termofusible, que requiere la aplicación de calor para proporcionar un sellado adecuado.Therefore, an object of the present invention is to provide a hole sealing element, in particular for vehicle body plate holes, avoiding the use of flux or hot melt material, which requires the application of heat to provide a suitable seal .

Tal como se muestra en las figuras, de acuerdo con la realización representada, el elemento de sellado de acuerdo con la presente invención está formado por dos cuerpos unidos entre sí, un cuerpo 1 provisto de medios de sellado, que se describirán a continuación, y un cuerpo adicional 4.As shown in the figures, according to the represented embodiment, the sealing element according to the present invention is formed by two bodies joined together, a body 1 provided with sealing means, which will be described below, and an additional body 4.
Dicho cuerpo 1, o cuerpo de sellado, comprende un primer labio de sellado 2 y un segundo labio de sellado 3. Dicho cuerpo 1 es de forma tubular y dichos primer y segundo labios de sellado 2, 3 están dispuestos en los extremos de dicho cuerpo 1 de forma tubular.Said body 1, or sealing body, comprises a first sealing lip 2 and a second sealing lip 3. Said body 1 is tubular in shape and said first and second sealing lips 2, 3 are arranged at the ends of said body 1 tubular.
El cuerpo 1 es de un material elastómero termoplástico, que permite el sellado sin la aplicación de calor, y el cuerpo adicional 4 es de un material más duro y más barato, lo que abarata el coste del elemento de sellado.The body 1 is made of a thermoplastic elastomer material, which allows sealing without the application of heat, and the additional body 4 is made of a harder and cheaper material, which lowers the cost of the sealing element.
Por su parte, el cuerpo adicional 4 comprende una cubierta 41 que cierra uno de los extremos del cuerpo 1 de forma tubular y que cubre el segundo labio de sellado 3, y una sección tubular 42 que está unido en la parte exterior del cuerpo 1 de forma tubular.For its part, the additional body 4 comprises a cover 41 that closes one of the ends of the tubular body 1 and that covers the second sealing lip 3, and a tubular section 42 that is joined on the outside of the body 1 of tubular shape.
Tal como se muestra en la figura 1, para sellar un orificio 6 realizado en una chapa 5, por ejemplo, una chapa metálica de una carrocería de un vehículo, se introduce el elemento de sellado en la dirección mostrada mediante la flecha en la figura 1.As shown in figure 1, to seal a hole 6 made in a sheet 5, for example, a metal sheet of a vehicle body, the sealing element is inserted in the direction shown by the arrow in figure 1 .
Al empezar a introducirse en el orificio 6, el primer labio de sellado 2 se dobla gracias a su naturaleza elástica, tal como se muestra en la figura 2.As it begins to enter the hole 6, the first sealing lip 2 bends due to its elastic nature, as shown in figure 2.
