DESCRIPCIÓN DESCRIPTION
OBJETO DEL INVENTO OBJECT OF THE INVENTION
El invento está pensado para evitar el robo o la extracción indeseada de combustible en un vehículo a motor, de tal manera que cuando el tapón de seguridad del invento está alojado en la entrada de un depósito de combustible, este tapón queda totalmente afianzado sin posibilidad de extracción, por medio de un mecanismo que comprende unos perfiles o barras planas articuladas y un tomillo sin fin, que aseguran mecánicamente el conjunto al depósito desde su interior, además el tapón del invento posee una cerradura y unas chapas de seguridad que imposibilitan el acceso al citado mecanismo, impidiendo posibles robos de combustible. The invention is intended to prevent theft or unwanted extraction of fuel in a motor vehicle, such that when the safety cap of the invention is housed in the inlet of a fuel tank, this cap is fully secured without the possibility of Extraction, by means of a mechanism comprising articulated flat bars or profiles and an endless thyme, that mechanically secure the assembly to the tank from its interior, in addition the cap of the invention has a lock and safety plates that prevent access to the cited mechanism, preventing possible theft of fuel.
El tapón de seguridad para depósito de combustible en vehículos del invento está conformado por una tapa, un mecanismo, una cerradura de seguridad, unas chapas de seguridad, un caequillo, una cadena y unos medios mecánicos de accionamiento, tal que, una llave de seguridad y una manivela. The safety cap for fuel tank in vehicles of the invention is made up of a cover, a mechanism, a safety lock, safety plates, a bushing, a chain and mechanical actuation means, such that a safety key and a crank.
El campo de aplicación de la invención se encuentra comprendido dentro del sector de la mecánica, concretamente en los tapones de motores de combustión intema en vehículos a motor de gran tonelaje. The field of application of the invention is comprised within the mechanics sector, specifically in the combustion engine plugs in large tonnage motor vehicles.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
En la actualidad los robos de combustible se han convertido en un coste añadido para empresas de transporte y autónomos, por lo que se hace necesario que los vehículos incorporen sistemas antirrobo en sus depósitos. Ante esta situación lo único que cabe es el conocimiento y la prevención. La autoprotección es la acción básica que debe adoptar cualquier conductor profesional a lo largo de la ruta e incluso el propio empresario, cuando el chofer de sus camiones no es de su entera confianza. Para ello es aconsejable montar en los depósitos dispositivos que impidan o avisen del trasvase de combustible, además de utilizar durante las paradas reglamentarias las áreas de descanso vigiladas. At present, fuel thefts have become an added cost for transport companies and freelancers, so it is necessary for vehicles to incorporate anti-theft systems in their tanks. Given this situation, all that is left is knowledge and prevention. Self-protection is the basic action that any professional driver must take along the route and even his own businessman, when the driver of your trucks is not your entire trust. For this, it is advisable to mount in the tanks devices that prevent or warn of the transfer of fuel, in addition to using the supervised rest areas during the regulatory stops.
Por todo ello, hay multitud de registros relacionados con diferentes tipos de tapones de seguridad o tapones antirrobo, destinados a la protección del combustible en depósitos de vehículos de gran tonelaje como camiones, furgonetas, autobuses o similar. Therefore, there are many records related to different types of security plugs or anti-theft plugs, intended for the protection of fuel in tanks of large tonnage vehicles such as trucks, vans, buses or similar.
Entre los registros encontrados, destacamos el modelo de utilidad ES0022845U titulado“Tapón para el depósito de gasolina de los automóviles, que impide la extracción furtiva del liquido” donde se divulga un tipo de tapón constituido fundamentalmente por una prolongación o cuerpo tubular, con rendijas verticales sobre sus superficies laterales y que se encuentra cerrado en su parte inferior, de tal manera que el conjunto permite la entrada de liquido al depósito, pero que imposibilita la introducción de un tubo o similar, por el que se pueda realizar la extracción del liquido desde el interior del depósito. Este registro actualmente de dominio público ha sido la base de diferentes tapones de seguridad para depósitos que actualmente se encuentran en el mercado, en los que se ha modificado la configuración en las superficies laterales de los cuerpos tubulares, concretamente en sus rendijas o paredes laterales por los que el combustible entra a través de las secciones diseñadas especialmente para la entrada de flujo, pero que imposibilita o dificulta la salida a través de los mismo. Among the records found, we highlight the utility model ES0022845U entitled “Cap for the fuel tank of cars, which prevents the furtive extraction of the liquid” where a type of cap consisting primarily of an extension or tubular body is disclosed, with vertical slits on its lateral surfaces and that it is closed in its lower part, in such a way that the assembly allows the entry of liquid into the tank, but that makes it impossible to introduce a tube or similar, by which the liquid can be extracted from The inside of the tank. This registry currently in the public domain has been the basis of different security caps for deposits that are currently on the market, in which the configuration on the lateral surfaces of the tubular bodies has been modified, specifically in their slits or side walls by those that the fuel enters through the sections specially designed for the flow inlet, but that makes it impossible or difficult to exit through them.
A diferencia del tapón de seguridad objeto del presente invento, los tapones de seguridad como los descritos necesitan de una instalación previa en la boca de entrada del depósito a proteger, sin embargo con el presente tapón de seguridad esta instalación se hace innecesaria porque el tapón en su conjunto puede ser introducido y extraído fácilmente cada vez que un usuario necesite repostar combustible, sin embargo una vez que el tapón está afianzado en la boca de entrada del depósito, se hace físicamente inviable acceder dentro del depósito puesto que el conjunto queda totalmente asegurado mecánicamente mediante el agarre de su mecanismo por debajo de la cavidad intema de la boca del depósito. De tal manera, que cuando el tapón de seguridad del invento intenta ser forzado gira sobre su propio eje, pero en ningún caso permite su extracción de la boca, hecho que es inexistente en el aludido registro. Por todo ello, consideramos que con el tapón de seguridad objeto del presente invento aporta mejoras y diferencias estructurales y técnicas diferentes a lo conocido en este sector. Unlike the safety cap object of the present invention, the safety plugs as described need a previous installation in the inlet port of the tank to be protected, however with this security cap this installation becomes unnecessary because the plug in its assembly can be easily introduced and removed every time a user needs to refuel, however once the cap is secured in the tank inlet, it becomes physically unfeasible to access inside the tank since the assembly remains fully mechanically secured by gripping its mechanism below the internal cavity of the tank mouth. Thus, when the safety cap of the invention tries to be forced, it rotates on its own axis, but in no case allows its extraction from the mouth, which is nonexistent in the aforementioned registry. Therefore, we consider that with the safety cap object of the present invention provides improvements and structural and technical differences different from what is known in this sector.
Otro registro a destacar es el modelo de utilidad ES0237626U titulado“Tapón para depósito de gasolina de vehículos automóviles" en el que se divulga un tapón que posee internamente un pivote excéntrico que sirve para el montaje de una placa que gira excéntricamente alrededor del citado pivote, el cual actúa como cerrojo de bloqueo del tapón y también presenta un saliente cilindrico por el que sobresale por dos ventanas una barra diametral, que sirve como barra de fijación del tapón a la boca del depósito de gasolina. La diferencia de este registro con el tapón de seguridad objeto del invento es fundamentalmente estructural y ftincional, es decir, estructural porque el tapón de seguridad del presente invento esté constituido por un mecanismo formado por unos perfiles o barras planas metálicas articuladas entre sí que se accionan por la actuación mecánica sobre un tomillo sin fin, que es totalmente diferente al presentado en el registro aludido; y funcional porque la resistencia a la extracción o violación que ofrece el tapón de seguridad del invento, mejora sustancialmente a la que presentan la .placa rectangular del registro señalado, puesto que la placa del registro aludido únicamente oftece resistencia en un punto del borde de la boca del recipiente, mientras que en la tapa del invento esta resistencia está presente en todos y cada uno de los puntos de la tapa del tapón contra la boca de entrada del depósito. El tapón del invento además, presenta un caequillo situado en tomo al cuello del depósito que evita en caso de robo la rotura de la boca del citado depósito, protegiendo de este modo el mecanismo interno del tapón; y también tiene una chapa de seguridad, situada sobre una cerradura, que mediante un precinto evita el acceso al mecanismo impidiendo la extracción del tapón de seguridad, incluso a los propios chóferes, todo ello de forma totalmente distinta y mejorada a lo conocido hasta el momento en este sector. Además, es conveniente destacar, que el tapón del invento agarra la boca del depósito tanto exterior como interiormente, mientras que en el caso del registro señalado anteriormente ES0237626U, este agarre o sujeción únicamente es posible por el interior. Another record to highlight is the utility model ES0237626U entitled “Cap for the fuel tank of motor vehicles” in which a cap is disclosed that internally has an eccentric pivot that is used to mount a plate that rotates eccentrically around said pivot, which acts as a locking bolt for the cap and also has a cylindrical projection through which a diametral bar protrudes through two windows, which serves as a bar for fixing the cap to the mouth of the fuel tank. The difference between this register and the cap The object of the invention is fundamentally structural and functional, that is to say structural because the safety cap of the present invention is constituted by a mechanism formed by metal profiles or bars articulated with each other that are actuated by the mechanical action on a thyme without purpose, which is totally different from the one presented in the aforementioned record; and functional because l The resistance to the extraction or violation offered by the safety cap of the invention substantially improves that presented by the rectangular plate of the indicated register, since the aforementioned registration plate only offers resistance at a point on the edge of the mouth of the container , while in the lid of the invention this resistance is present in each and every one of the points of the cap of the cap against the inlet mouth of the tank. In addition, the cap of the invention has a bushing located on the neck of the tank that prevents breakage of the mouth of said tank in case of theft, thereby protecting the internal mechanism of the cap; and also has a safety plate, located on a lock, which by means of a seal prevents access to the mechanism preventing the removal of the safety plug, even to the drivers themselves, all in a totally different way and improved to what is known so far In this sector. In addition, it should be noted that the cap of the invention it grabs the mouth of the tank both externally and internally, while in the case of the register indicated above ES0237626U, this grip is only possible from the inside.
Por todo ello el tapón de seguridad del presente invento aporta mejoras diferenciales, respecto de los tapones convencionales para depósito de combustible en vehículos a motor, por medio de una configuración estructural diferente y mejorada que la presentada en los tapones conocidos hasta la fecha. Estas diferencias hacen que el tapón del invento sea más resistente y seguro a posibles robos o manipulaciones indeseadas; además, otra consecuencia de la diferencia estructural de su mecanismo es que el tapón del invento puede ser adaptado a cualquier altura del cuello de la boca de un depósito, de forma totalmente distinta a la que presentan los tapones de seguridad conocidos en la actualidad, los cuales presentan una altura fija de agarre. Así pues, y a tenor de lo anteriormente expuesto, con el tapón de seguridad objeto del invento se va un paso más allá en el sector de los tapones para motores de combustión interna, puesto que, mediante una determinada configuración, se obtiene un tipo de tapón de seguridad diferente, mejorando lo conocido hasta el momento en este sector. Therefore, the safety cap of the present invention provides differential improvements, compared to conventional fuel tank caps in motor vehicles, by means of a different and improved structural configuration than that presented in the caps known to date. These differences make the cap of the invention more resistant and safe against possible theft or unwanted manipulation; In addition, another consequence of the structural difference of its mechanism is that the cap of the invention can be adapted to any height of the neck of the mouth of a tank, in a totally different way than the safety caps currently known, which have a fixed grip height. Thus, and according to the above, with the safety cap object of the invention goes a step further in the sector of the plugs for internal combustion engines, since, through a certain configuration, a type of plug is obtained of different security, improving what is known so far in this sector.
A continuación, se realiza una detallada descripción del invento que completa estas ideas generales introducidas en este punto. Next, a detailed description of the invention is completed that completes these general ideas introduced at this point.

Por lo que, cuando el tapón del invento se encuentra ubicado en el interior de la boca de un depósito, el mecanismo que lo compone se activa por medio de una manivela que hace girar un tomillo sin fin que solidariamente mueve unos perfiles o barras planas, que afianza mecánicamente el mecanismo del tapón dentro del depósito, sin posibilidad de extracción. The safety cap for fuel tank in vehicles of the invention is comprised of a cover, a mechanism, a safety lock, safety plates, a bushing, a chain and mechanical actuation means, such as a safety key and a crank; in such a way that the mechanism is attached inferiorly to the lid, the security lock is housed inside the body of the lid, the safety plates are located on the plate protecting the lock, the bushing is located around the neck of the mouth of the tank and the chain is fixed at one end of the mechanism. The safety cap of the invention is constituted by rigid elements, preferably metallic and structurally configured so that all the parts that compose it, except the upper face of the lid, are introduced into the cavity of the inlet mouth of any fuel tank of a motor vehicle. So, when the cap of the invention is located inside the mouth of a tank, the mechanism that composes it is activated by means of a crank that rotates an endless thyme that in solidarity moves flat profiles or bars, that mechanically strengthens the mechanism of the cap inside the tank, without the possibility of extraction.
La lapa es la pieza superior del tapón de seguridad, y está formada por un cuerpo que presenta superiormente una superficie circular plana, cuyo perímetro tiene un diámetro superior a la boca del depósito; mientras que inferiormente tiene una superficie cilindrica, cuyo perímetro es de un diámetro menor que la embocadura del depósito. Se destaca que, en la referida superficie circular plana, concretamente en su contorno inferior, hay una cavidad perimetral que está en contacto directo con la superficie de la boca del depósito, que es la superficie donde se produce el agarre entre el tapón y la boca del depósito. En la parte central de la tapa además hay una oquedad donde se aloja una cerradura de seguridad. Otro detalle del invento es que, a ambos lados de la citada tapa, esta posee fijadas unas pletinas por donde se une un mecanismo. The barnacle is the upper part of the safety cap, and is formed by a body that has a flat circular surface superiorly, whose perimeter has a diameter greater than the mouth of the tank; while inferiorly it has a cylindrical surface, whose perimeter is of a smaller diameter than the mouth of the tank. It is emphasized that, in the aforementioned flat circular surface, specifically in its lower contour, there is a perimeter cavity that is in direct contact with the surface of the tank mouth, which is the surface where the grip between the cap and the mouth occurs of the deposit. In the central part of the lid there is also a recess where a security lock is housed. Another detail of the invention is that, on both sides of said cover, it has fixed plates where a mechanism is attached.
Este mecanismo está conformado por unos perfiles o barras planas rígidas articuladas entre si, de tal manera que un tomillo sin fin, que se encuentra alojado en un orificio pasante que posee la oquedad central de la tapa, actúa como elemento motriz. Las barras se posicionan simétricamente al eje central de la tapa y dos de ellas están unidas simétricamente a la tapa por cada una de las pletinas, citas previamente. El tomillo sin fin que coincide en posición con el eje central de la tapa está afianzado convenientemente a la misma mediante una tuerce tope o similar. Este tomillo sin fin es el medio por el cual se activa el mecanismo, es decir, las barras articulan solidariamente al giro del tomillo sin fin por medio de una tuerca de avance o tuerca móvil con aletas. De esta manera el tomillo sin fin, que es accesible con una manivela a través de la cavidad de la tapa, gira sobre su eje y le transmite el movimiento vertical a la tuerca móvil, la cual a su vez transmite su movimiento a las barras articuladas en sus aletas. Se hace notar que el tomillo sin fin es accesible por medio de la citada manivela cuando sobre la tapa no ha sido introducida una cerradura de seguridad, descrita más adelante. This mechanism is made up of rigid flat profiles or bars articulated with each other, so that an endless thyme, which is housed in a through hole that has the central hole of the lid, acts as a driving element. The bars are positioned symmetrically to the central axis of the lid and two of them are symmetrically attached to the lid by each of the plates, previously cited. The endless thyme that coincides with the central axis of the lid is conveniently secured to it by means of a stop nut or the like. This endless thyme is the means by which the mechanism is activated, that is, the bars articulate in solidarity with the rotation of the endless thyme by means of a feed nut or mobile nut with fins. In this way the endless thyme, which is accessible with a crank through the cavity of the lid, it rotates on its axis and transmits the vertical movement to the mobile nut, which in turn transmits its movement to the articulated bars on its fins. It is noted that the endless thyme is accessible by means of said crank when a safety lock, described below, has not been introduced on the cover.
Por todo ello, cuando el movimiento de la referida tuerca móvil es hacia abajo, las barras que componen el mecanismo se abren bajo las paredes internas de la boca del depósito, de tal manera que los extremos de al menos dos barras planas sobresalen por la boca interna del depósito, quedando el conjunto asegurado o agarrado inferiormente a la boca. De este modo, el conjunto queda asegurado axialmente sin posibilidad de extracción, pero al mismo tiempo permite la rotación del conjunto sobre su propio eje. De manera análoga, cuando sobre el tomillo sin fin se realiza un giro en sentido contrario al descrito, la tuerca móvil asciende de tal manera que las barras que se mueven solidariamente al movimiento vertical de la tuerca se pliegan sobre sí mismas dejando de sobresalir por debajo de la boca interna del depósito y el conjunto del tapón de seguridad del invento puede ser extraído de la boca. Therefore, when the movement of the said mobile nut is down, the bars that make up the mechanism open under the inner walls of the tank mouth, so that the ends of at least two flat bars protrude through the mouth internal of the tank, the assembly being secured or held inferiorly to the mouth. In this way, the assembly is axially secured without the possibility of extraction, but at the same time it allows the assembly to rotate on its own axis. Similarly, when a twist is made on the endless thyme in the opposite direction to that described, the movable nut rises in such a way that the bars that move in solidarity with the vertical movement of the nut fold over themselves, no longer protruding below from the inner mouth of the tank and the safety cap assembly of the invention can be removed from the mouth.
Se hace notar que, para reforzar exteriormente el cuello de la boca del depósito, adicionalmente el tapón del invento incorpora un casquillo que está ubicado exteriormente al cuello del depósito. Este casquillo protege todo el perímetro exterior del cuello de la boca, evitando que el cuello del depósito pueda ser forzado o doblado con algún tipo de herramienta. Entre el casquillo y el cuello del depósito hay una holgura que permite el giro libre de esta protección. La inclusión de este casquillo hace que el conjunto tenga un elemento de seguridad adicional no presente en los tapones existentes en el mercado. It is noted that, in order to externally reinforce the neck of the tank mouth, additionally the cap of the invention incorporates a bushing that is located externally to the neck of the tank. This bushing protects the entire outer perimeter of the neck of the mouth, preventing the neck of the tank from being forced or bent with some type of tool. Between the bushing and the neck of the tank there is a clearance that allows the free rotation of this protection. The inclusion of this bushing means that the set has an additional security element not present in the existing caps in the market.
Otro detalle del invento es que en el extremo preferentemente de una de estas barras, hay fijada una cadena metálica que impide que el conjunto del tapón de seguridad del invento se pierda o extravíe cuando éste es extraído del depósito, por ejemplo, en labores de repostaje o similar. Una vez que el mecanismo está convenientemente ajustado tanto interna como externamente en la boca del depósito, en la oquedad central de la tapa citada previamente, se aloja una cerradura de seguridad. Esta cerradura de seguridad es cilindrica y sus dimensiones son tales que una vez que está alojada en el interior de la aludida oquedad, las holguras entre ellas son inexistentes. Se ha de destacar que en un punto medio de esta cerradura sobresale una pestaña, la cual queda alojada en un hueco interno de la propia oquedad. Esta pestaña es accionada por medio de una llave de seguridad. Another detail of the invention is that at the end preferably of one of these bars, a metal chain is fixed that prevents the assembly of the safety cap of the invention from being lost or lost when it is removed from the tank, for example, in refueling. or similar. Once the mechanism is conveniently adjusted both internally and externally in the mouth of the tank, in the central recess of the previously mentioned lid, a safety lock is housed. This security lock is cylindrical and its dimensions are such that once it is housed inside the aforementioned recess, the clearances between them are non-existent. It should be noted that a tab protrudes at a midpoint of this lock, which is housed in an internal hollow of the hole itself. This tab is operated by means of a security key.
Esta cerradura está protegida superiormente por unas chapas que permiten la introducción de un precinto a través de ellas, impidiendo de este modo la extracción indeseada del tapón. Ambas placas están situadas sobre el cuerpo superior de la tapa, de tal manera que una de ellas gira excéntricamente sobre la cara vista de la cerradura a través de un agujero de tipo remache; mientras que la otra chapa, está fija sobre la superficie de la tapa mediante soldadura o similar. Las dos chapas poseen en sus cuerpos verticales un agujero pasante, de tal manera que cuando ambas están enfrentadas, estos agujeros coinciden en un mismo punto por el cual se puede introducir un fleje o precinto que impide la apertura de la cerradura y por tanto la extracción del tapón del depósito. La inclusión de estos elementos presenta la ventaja técnica de tener un segundo elemento de seguridad frente a los robos o aperturas indeseadas. This lock is protected superiorly by plates that allow the introduction of a seal through them, thus preventing unwanted removal of the plug. Both plates are located on the upper body of the lid, such that one of them rotates eccentrically on the face seen of the lock through a rivet-type hole; while the other sheet is fixed on the surface of the cover by welding or the like. The two plates have a through hole in their vertical bodies, so that when both are facing each other, these holes coincide at the same point by which a strap or seal can be introduced that prevents the opening of the lock and therefore the extraction of the tank cap. The inclusion of these elements has the technical advantage of having a second security element against theft or unwanted openings.
Por todo ello, cuando el tapón (te seguridad en su conjunto está alojado en la boca de entrada de un depósito de combustible, este tapón queda totalmente agarrado a la boca del depósito tanto exterior como internamente, sin posibilidad de extracción. Por lo que el tapón del invento queda asegurado mecánicamente en la boca del depósito sin posibilidad de extracción, siendo posible el giro del conjunto sobre su propio eje, por lo que el depósito queda totalmente cerrado evitando al mismo tiempo manipulaciones de apertura indeseadas. Therefore, when the plug (safety as a whole is housed in the inlet mouth of a fuel tank, this cap is fully attached to the mouth of the tank both externally and internally, without the possibility of extraction. The cap of the invention is mechanically secured in the mouth of the tank without the possibility of extraction, the rotation of the assembly being possible on its own axis, whereby the tank is completely closed while avoiding unwanted opening manipulations.

DESCRIPCIÓN DE LOS DIBUJOS Tal y como se representa en la figura 1 y en la figura 2, el tapón (1) de seguridad del invento está alojado en el interior de la boca (21 ) de un depósito (2) de combustible, de tal manera que todas las partes del tapón (1) de seguridad exceptuando su cara superior, correspondiente a la cara superior de una tapa (12), se encuentran embebidas dentro del depósito (2). DESCRIPTION OF THE DRAWINGS As shown in Figure 1 and Figure 2, the safety cap (1) of the invention is housed inside the mouth (21) of a fuel tank (2), such that all parts of the safety plug (1) except its upper face, corresponding to the upper face of a lid (12), are embedded inside the tank (2).
Por todo ello, cuando el tapón (1) de seguridad en su conjunto está alojado en la boca (21) de entrada de un depósito (2) de combustible, este tapón (1) queda totalmente agarrado a la boca (21) del depósito (2) tanto interna como externamente, sin posibilidad de extracción. Así pues, tal y como muestran las figuras 1 y 2, el tapón (1) de seguridad queda asegurado mecánicamente en la boca (21) del depósito (2) desde su interior, por medio de un mecanismo (13) formado por unas barras (131) planas; y desde su exterior, por medio de una tapa (12) que afianza superiormente el conjunto a la boca (21) del depósito (2), además de por un casquillo (15) ubicado perimetralmente entre la tapa (12) y el depósito (2). Por lo que el tapón (1) queda totalmente inmovilizado sobre la superficie de la boca (21) del referido depósito (2), el cual queda totalmente cerrado. Therefore, when the safety plug (1) as a whole is housed in the inlet mouth (21) of a fuel tank (2), this plug (1) is fully seized to the mouth (21) of the tank (2) both internally and externally, with no possibility of extraction. Thus, as shown in Figures 1 and 2, the safety plug (1) is mechanically secured in the mouth (21) of the tank (2) from its inside, by means of a mechanism (13) formed by bars (131) flat; and from the outside, by means of a cover (12) that superiorly fastens the assembly to the mouth (21) of the tank (2), in addition to a bushing (15) located perimeter between the cover (12) and the tank ( two). So the cap (1) is completely immobilized on the surface of the mouth (21) of the aforementioned tank (2), which is completely closed.
Por otro lado la figura 3 y la figura 4, muestran las distintas partes que conforman el tapón (1) de seguridad del invento, el cual comprende una lapa (12), un mecanismo (13) unido ínferiormente a la tapa (12), una cerradura (14) de seguridad alojada en el interior del cuerpo de la tapa (12), unas chapas (16) de seguridad situadas sobre la tapa (12) protegiendo la cerradura (14), un caequillo (15) ubicado en tomo el cuello de la boca (21) del depósito (2), una cadena (17), y unos medios mecánicos de accionamiento, tal que, una llave de seguridad y una manivela (no representados) que actúan respectivamente sobre la cerradura (14) de seguridad y el mecanismo (13). On the other hand, Figure 3 and Figure 4 show the different parts that make up the safety plug (1) of the invention, which comprises a barnacle (12), a mechanism (13) attached inferiorly to the cover (12), a security lock (14) housed inside the body of the lid (12), safety plates (16) located on the lid (12) protecting the lock (14), a bushing (15) located on the neck of the mouth (21) of the tank (2), a chain (17), and mechanical actuation means, such that, a safety key and a crank (not shown) acting respectively on the lock (14) of Safety and mechanism (13).
El tapón de seguridad (1 ) del invento es rígido, preferentemente metálico y se aloja en el interior de la boca (21) de un depósito (2) de combustible, de tal manera que todas las partes del tapón de seguridad (1), exceptuando su cara superior correspondiente a la tapa (12), se encuentran introducidas dentro del depósito (2). Tal y como se detalla en la figura 5, figura 6 y figura7, la tapa (12) es la pieza superior del tapón de seguridad (1), y está formada por un cuerpo que presenta superiormente una superficie circular plana cuyo perímetro tiene un diámetro superior a la boca (21) del depósito (2); mientras que inferiormente tiene una superficie cilindrica, cuyo perímetro es de un diámetro menor que la embocadura del depósito (2). Destacando que, en la referida superficie circular plana, concretamente en su contorno inferior, hay una cavidad (121) perimetral que está en contacto directo con la superficie de la boca (21) del depósito (2), que es la superficie donde se produce el agarre entre el tapón (1) y la boca (21) del depósito (2). En la parte central de la tapa (12) además hay una oquedad (122) donde se aloja una cerradura (14) de seguridad. Otro detalle del invento es que a ambos lados de la citada lapa (12), esta posee fijadas a ambos lados unas pletinas (123) por donde se une un mecanismo (13). The safety cap (1) of the invention is rigid, preferably metallic and is housed inside the mouth (21) of a fuel tank (2), such that all parts of the safety cap (1), except for its upper face corresponding to the lid (12), they are inserted into the tank (2). As detailed in Figure 5, Figure 6 and Figure 7, the cover (12) is the upper part of the safety plug (1), and is formed by a body that has a flat circular surface superiorly whose perimeter has a diameter upper than the mouth (21) of the tank (2); while inferiorly it has a cylindrical surface, whose perimeter is of a smaller diameter than the mouth of the tank (2). Stressing that, in the aforementioned flat circular surface, specifically in its lower contour, there is a perimeter cavity (121) that is in direct contact with the surface of the mouth (21) of the reservoir (2), which is the surface where it is produced the grip between the cap (1) and the mouth (21) of the tank (2). In the central part of the lid (12) there is also a recess (122) where a security lock (14) is housed. Another detail of the invention is that on both sides of said barnacle (12), it has fixed on both sides plates (123) where a mechanism (13) is attached.
En la figura 3 y en la figura 4 se muestra como este mecanismo (13), está conformado por unos perfiles o barras (131) planas rígidas articuladas entre sí, de tal manera que un tomillo sin fin (132), que se encuentra alojado en un orificio pasante que posee la oquedad (122) central de la tapa (1), actúa como elemento motriz. Las barras (131) se posicionan simétricamente al eje central de la tapa (12) y dos de ellas están unidas simétricamente a la tapa (12) por cada una de las pletinas (123), citas previamente. El tomillo sin fin (132) que coincide en posición con el eje central de la tapa (12) y además está afianzado a la misma mediante una tuerca tope o similar. Este tomillo sin fin (132) es el medio por el cual se activa el mecanismo (13), es decir, las barras (131) articulan solidariamente al giro del tomillo sin fin (132) por medio de una tuerca móvil (133) con aletas. De tal manera que el tomillo sin fin (132), que es accesible superiormente por medios mecánicos con una manivela a través de la oquedad (122) de la tapa (12), gira sobre su eje y le transmite el movimiento vertical a la tuerca móvil (133), la cual a su vez transmite su movimiento a las barras (131) articuladas en sus aletas. In figure 3 and in figure 4 it is shown how this mechanism (13), is formed by rigid flat profiles or bars (131) articulated with each other, such that an endless thyme (132), which is housed in a through hole that has the central hole (122) of the cover (1), it acts as a driving element. The bars (131) are positioned symmetrically to the central axis of the cover (12) and two of them are symmetrically connected to the cover (12) by each of the plates (123), previously cited. The endless thyme (132) that coincides in position with the central axis of the cover (12) and is also secured to it by means of a stop nut or the like. This endless thyme (132) is the means by which the mechanism (13) is activated, that is to say, the bars (131) articulate jointly to the rotation of the endless thyme (132) by means of a mobile nut (133) with fins In such a way that the endless thyme (132), which is superiorly accessible by mechanical means with a crank through the recess (122) of the cover (12), rotates on its axis and transmits the vertical movement to the nut mobile (133), which in turn transmits its movement to the bars (131) articulated in its fins.
Por todo ello, tal y como muestra la posición representada en la figura 3, cuando el movimiento de la referida tuerca móvil (133) es hacia abajo, las barras (131) que componen el mecanismo están desplegadas o abiertas bajo las paredes internas de la boca (21 ) del depósito (2), de tal manera que los extremos de dos barras (131) planas sobresalen por la boca (21) intema del depósito (2), quedando el conjunto asegurado o agarrado inferiormente a la boca (21). De este modo, el conjunto queda afianzado axialmente sin posibilidad de extracción, permitiendo al mismo tiempo la rotación del conjunto sobre su propio eje. Therefore, as shown in the position shown in Figure 3, when the movement of the said mobile nut (133) is down, the bars (131) that make up the mechanism are deployed or open under the internal walls of the mouth (21) of the tank (2), in such a way that the ends of two flat bars (131) protrude through the mouth (21) inside the tank (2), the assembly being secured or held inferiorly to the mouth (21 ). In this way, the assembly is axially secured without the possibility of extraction, while allowing the assembly to rotate on its own axis.
De manera análoga, la figura 4 representa el pliegue de las barras (131) del mecanismo (13) cuando sobre el tomillo sin fin (132) se realiza un giro en sentido contrario al descrito previamente. En este caso, cuando sobre el tomillo sin fin (132) realiza el giro, la tuerca móvil (133) asciende de tal manera que las barras (131) que se mueven solidariamente al movimiento vertical de la tuerca, se pliegan sobre si mismas dejando de sobresalir por debajo de la boca (21) interna del depósito (2) y el conjunto del tapón (1) de seguridad del invento puede ser extraído de la boca (21). Similarly, Figure 4 represents the folding of the bars (131) of the mechanism (13) when a rotation is made on the endless thyme (132) in the opposite direction to that previously described. In this case, when on the endless thyme (132) it makes the turn, the mobile nut (133) ascends in such a way that the bars (131) that move in solidarity with the vertical movement of the nut, fold over themselves leaving from protruding below the internal mouth (21) of the tank (2) and the assembly of the safety cap (1) of the invention can be removed from the mouth (21).
Se hace notar que para reforzar exteriormente el cuello de la boca (21) del depósito (2), adicionalmente el tapón (1) del invento incorpora un casquillo (15) entorno al cuello del depósito que protege todo el perímetro exterior de la boca (21). Entre el casquillo (15) y el cuello del depósito (2) hay una holgura que permite el giro libre de esta protección. It is noted that to externally reinforce the neck of the mouth (21) of the tank (2), additionally the cap (1) of the invention incorporates a sleeve (15) around the neck of the tank that protects the entire outer perimeter of the mouth ( twenty-one). Between the bushing (15) and the neck of the tank (2) there is a clearance that allows the free rotation of this protection.
Otro detalle del invento es que, en un extremo, preferentemente de una de estos perfiles o barras (131) planas, la tapa (1) tiene fijada una cadena (15) metálica que impide que el conjunto del tapón de seguridad (1) se pierda o extravíe cuando este tapón (1) es extraído del depósito (2). Another detail of the invention is that, at one end, preferably of one of these flat profiles or bars (131), the cover (1) has a metal chain (15) fixed that prevents the safety plug assembly (1) from being lose or lose when this plug (1) is removed from the tank (2).
Una vez que el mecanismo (13) está convenientemente ajustado en la boca (21) del depósito (2), en la oquedad (122) central de la tapa (12) citada previamente, se aloja una cerradura (14) de seguridad. Esta cerradura (14) de seguridad es cilindrica y sus dimensiones son tales que una vez que está alojada en la aludida oquedad (122), las holguras entre ellas son inexistentes. Se hace notar, que en un punto medio de esta cerradura (14) sobresale una pestaña (141), la cual queda alojada en un hueco intemo de la propia oquedad (122), siendo esta pestaña (144) accionada superiormente por medio de una llave de seguridad (no representada). Once the mechanism (13) is conveniently adjusted in the mouth (21) of the tank (2), in the central recess (122) of the cover (12) previously mentioned, a safety lock (14) is housed. This security lock (14) is cylindrical and its dimensions are such that once it is housed in the aforementioned recess (122), the clearances between them are non-existent. It is noted that, at a midpoint of this lock (14), a flange (141) protrudes, which is housed in an internal hollow of the cavity itself (122), this tab (144) being operated superiorly by means of a security key (not shown).
Esta cerradura (14) está protegida superiormente por unas chapas (16) que permiten la introducción de un precinto a través de ellas, impidiendo de este modo la extracción indeseada del tapón (1). Ambas chapas (16) están situadas sobre el cuerpo superior de la tapa (1), de tal manera que una de ellas gira por un agujero excéntrico (161) sobre la cara vista de la cerradura (14), mientras que la otra está fija sobre la superficie de la tapa (1) mediante soldadura o similar. Asi pues, tal y como se representa en la figura 8, las dos chapas (16) poseen en sus cuerpos verticales un agujero pasante (162), de tal manera que cuando ambas están enfrentadas, estos agujeros coinciden en un mismo eje por el cual puede introducirse un fleje o precinto, que impide la separación entre ambas chapas (16) y por lo tanto la apertura de la cerradura (14) que se encuentra inferíormente. This lock (14) is protected superiorly by plates (16) that allow the introduction of a seal through them, thus preventing unwanted removal of the plug (1). Both plates (16) are located on the upper body of the cover (1), such that one of them rotates through an eccentric hole (161) on the exposed face of the lock (14), while the other is fixed on the surface of the cover (1) by welding or the like. Thus, as shown in Figure 8, the two plates (16) have in their vertical bodies a through hole (162), such that when both are facing, these holes coincide on the same axis by which a strap or seal can be introduced, which prevents the separation between both plates (16) and therefore the opening of the lock (14) that is inferiorly.
Por todo ello, cuando el tapón (1) de seguridad en su conjunto está alojado en la boca (21) de entrada de un depósito (2) de combustible, este tapón (1) queda totalmente agarrado a la boca (21) tanto interior como exteriormente, sin posibilidad de extracción y siendo posible el giro del mismo sobre su propio eje, quedando en todo momento el depósito (2) totalmente cerrado. Therefore, when the safety plug (1) as a whole is housed in the inlet mouth (21) of a fuel tank (2), this plug (1) is fully seized to the mouth (21) both inside as externally, without the possibility of extraction and its rotation being possible on its own axis, the tank (2) being completely closed at all times.
