Tornillo para madera con émbolo de activación que contiene productos endurecibles SECTOR DE LA TÉCNICA Wood screw with activation plunger containing hardenable products TECHNICAL SECTOR
La presente invención se refiere a un tornillo para madera. Es aplicable al sector de la madera y el mueble, y más concretamente su configuración lo define especialmente eficaz para la sujeción de manetas en picaportes y en la fijación de herrajes.The present invention relates to a wood screw. It is applicable to the wood and furniture sector, and more specifically its configuration defines it as particularly effective for fastening handles on doorknobs and for fixing hardware.
El objeto principal de la presente invención es proporcionar un medio de fijación con capacidades mejoradas en la fijación de herrajes, de fácil utilización, bajo coste y que represente un medio de fijación eficaz y definitivo.The main object of the present invention is to provide a fixing means with improved capabilities in fixing hardware, easy to use, low cost and representing an effective and definitive fixing means.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Los tornillos de madera son ampliamente conocidos como medios de fijación entre herrajes y la madera de la hoja soporte. Los convencionales se conforman de un cilindro sólido, generalmente metálico, alrededor del cual discurre una rosca helicoidal. En un extremo se ensancha para modelar la cabeza, donde está dispuesto un rebaje con la huella del destornillador. Un destornillador encaja en este rebaje. Para habilitar su inserción directa en un objeto, su otro extremo es puntiagudo.Wood screws are widely known as means of fixing between hardware and the wood of the support sheet. The conventional ones are made up of a solid cylinder, generally metallic, around which a helical thread runs. At one end it is widened to shape the head, where a recess with the screwdriver footprint is arranged. A screwdriver fits into this recess. To enable its direct insertion into an object, its other end is pointed.
Se conoce de forma generalizada que uno de sus principales problemas es que se suelen soltar o aflojar debido a movimientos, oscilaciones o vibraciones. Este problema se complica en mayor medida por sus consecuencias derivadas ya que, el reapriete de tornillos convencionales en la madera, PVC u otros materiales plásticos de los que está fabricada la hoja soporte, acaba por deteriorar sus fibras internas. Y finalmente, cuando el par de apriete del tornillo supera el par resistente del material de la hoja soporte, la zona de inserción de los tornillos pierde su consistencia y se rompe, imposibilitando la fijación del herraje de forma firme y funcional.It is widely known that one of their main problems is that they tend to come loose or loosen due to movements, oscillations or vibrations. This problem is further complicated by its derived consequences since the retightening of conventional screws in wood, PVC or other plastic materials from which the support sheet is made, ends up deteriorating its internal fibers. And finally, when the tightening torque of the screw exceeds the resistant torque of the material of the support sheet, the area of insertion of the screws loses its consistency and breaks, making it impossible to fix the hardware in a firm and functional way.
Uno de los casos más representativos de esta problemática lo simboliza la unión de manetas en picaportes con tornillos convencionales, máxime cuando la intensidad de uso de la maneta es media o alta ya que, en estas situaciones debido al alto uso de la maneta los tornillos tienden a soltarse enseguida, demandando ser reapretados de forma constante, y es en esta casuística cuando la frecuencia de reapriete debe ser más alta, por lo tanto, la rotura de las fibras internas del material de la hoja soporte acontece con mayor celeridad.One of the most representative cases of this problem is symbolized by the union of handles on handles with conventional screws, especially when the intensity of use of the handle is medium or high since, in these situations due to the high use of the handle. The bolts tend to loosen immediately, demanding to be constantly retightened, and it is in this case when the frequency of retightening must be higher, therefore, the breakage of the internal fibers of the material of the support sheet occurs more quickly .
Otro motivo que agrava y propicia drásticamente esta desfavorable situación, surge cuando el material de la hoja soporte no es macizo, sino de materiales conglomerados. Además, se conoce de forma generalizada que esta problemática también es motivada en los casos donde el grosor de la hoja soporte es fino, en este caso el problema se origina por fresado de vaciado que realiza el carpintero en el interior de la hoja soporte para emplazar el mecanismo del picaporte en su posición correcta de trabajo.Another reason that drastically aggravates and favors this unfavorable situation arises when the material of the support sheet is not solid, but made of conglomerate materials. In addition, it is widely known that this problem is also caused in cases where the thickness of the support sheet is thin, in this case the problem originates from the hollow milling carried out by the carpenter inside the support sheet to place the latch mechanism in its correct working position.
La solución tradicional a esta problemática que aporta la técnica anterior consiste en la introducción de dos chapas metálicas en ambas caras de la hoja soporte, dispuestas de tal forma que refuerzan con metal los puntos exactos donde deben situarse los tornillos de fijación, y en la substitución de los tirafondos de madera o plástico por tornillos comunes para metal. Esta operación introduce roscas de metal reparando la zona exacta de fijación.The traditional solution to this problem provided by the prior art consists in the introduction of two metal sheets on both sides of the support sheet, arranged in such a way as to reinforce with metal the exact points where the fixing screws should be located, and in the replacement of wood or plastic lag screws by common metal screws. This operation introduces metal threads repairing the exact area of fixation.
Otra solución alternativa más costosa, podría ser cambiar todo el mecanismo por otro distinto donde las ubicaciones exactas de fijación de los tornillos fueran diferentes a las del elemento a substituir, y por geometrías distintas, la zona deteriorada de la hoja soporte perdería su interés como punto clave en la sujeción del mecanismo.Another more expensive alternative solution could be to change the entire mechanism for a different one where the exact locations for fixing the screws are different from those of the element to be replaced, and due to different geometries, the damaged area of the support sheet would lose its interest as a point key in clamping the mechanism.
En ambas maneras de resolver el problema de forma convencional, los costes de reparación son siempre muy superiores a los de la presente invención. Adicionalmente debe considerarse las molestias recurrentes propias de la problemática expuesta ya que, por el simple uso de la puerta o ventana, a partir del momento en que surge el problema no hay forma de eludirlo. Primero empieza a debilitarse el material de la hoja soporte, a continuación se requiere de mantenimiento periódico cada vez con mayor frecuencia y finalmente las fibras internas de la hoja soporte se deterioran de forma definitiva inutilizando el mecanismo en la mayoría de los casos.In both ways of solving the problem in a conventional way, the repair costs are always much higher than in the present invention. Additionally, the recurring annoyances typical of the problem presented must be considered since, by the simple use of the door or window, from the moment the problem arises there is no way to avoid it. First, the material of the support sheet begins to weaken, then periodic maintenance is required with increasing frequency and finally the internal fibers of the support sheet deteriorate permanently, rendering the mechanism unusable in most cases.
El solicitante de la presente invención desconoce de la existencia de otros antecedentes que permitan resolver de forma satisfactoria la problemática planteada. The applicant of the present invention is unaware of the existence of other antecedents that allow the problem raised to be satisfactorily resolved.

De acuerdo con la invención para resolver la problemática expuesta, el tornillo para madera con émbolo de activación que contiene productos endurecibles objeto de la invención comprende: un cuerpo principal, un componente de resina, un componente endurecedor y un émbolo de activación. A continuación detallaremos estos elementos.According to the invention, to solve the problems set forth, the wood screw with an activation piston containing hardenable products that is the object of the invention comprises: a main body, a resin component, a hardener component and an activation piston. We will detail these elements below.
El cuerpo principal comprende una estructura cilíndrica hueca que discurre desde base de la zona cónica de la punta hasta la cabeza de tornillo, en cuyo interior se ubica el componente de resina, el componente endurecedor y el émbolo de activación. Además, en la parte delantera de la punta presenta al menos un orificio lateral que comunica la cara exterior, alrededor de la cual discurre la rosca helicoidal con la cavidad cilíndrica interior donde se aloja la resina y el endurecedor.The main body comprises a hollow cylindrical structure that runs from the base of the conical area of the tip to the screw head, inside which the resin component, the hardener component and the activation piston are located. Furthermore, in the front part of the tip it has at least one lateral hole that communicates the outer face, around which the helical thread runs with the inner cylindrical cavity where the resin and hardener are housed.
Ambos componentes tanto el de resina como el endurecedor comprenden una envoltura o pueden estar contenidos por membranas, alojándose en la parte más profunda de la cavidad cilíndrica hueca del cuerpo principal.Both resin and hardener components comprise a shell or they may be contained by membranes, staying in the deepest part of the hollow cylindrical cavity of the main body.
El émbolo activador presenta una forma cilíndrica elongada, cuyo diámetro es ligeramente inferior a la cavidad cilíndrica del cuerpo principal. Este está destinado a ser introducido por la cabeza del tornillo en el interior de esta.The activating plunger has an elongated cylindrical shape, the diameter of which is slightly less than the cylindrical cavity of the main body. This is intended to be inserted through the head of the screw inside it.
En una realización preferente el cuerpo principal aloja en la parte más profunda del hueco cilíndrico interior el componente de resina, a continuación el componente endurecedor y en último lugar el émbolo de activación.In a preferred embodiment, the main body houses the resin component, then the hardener component, and lastly the activation plunger in the deepest part of the inner cylindrical hollow.
La activación de los componentes endurecibles se realiza el instante previo a la introducción del tornillo en la hoja soporte. Consiste en introducir el émbolo de activación hacia el interior del tornillo con la punta del destornillador, de esta forma se comprimen los componentes obligándolos a salir del cuerpo principal al exterior por los orificios laterales. En esta acción, el émbolo queda completamente encajado en el interior de la cavidad la cilíndrica del cuerpo principal, dejando libre la huella de apriete de cabeza del tornillo. Por los orificios laterales de la punta del tornillo salen las gotas de los componentes endurecibles predispuestos para ser mezclados.The hardening components are activated the moment before the screw is inserted into the support sheet. It consists of introducing the activation plunger into the screw with the tip of the screwdriver, in this way the components are compressed forcing them to exit the main body to the outside through the side holes. In this action, the plunger remains completely embedded inside the cylindrical cavity of the main body, leaving free the tightening footprint of the screw head. Drops of the hardenable components predisposed to be mixed come out through the side holes of the screw tip.
A continuación se introduce el tornillo, usualmente con destornillador en la hoja soporte, y por el propio movimiento de giro se mezclan los componentes propiciando de forma intrínseca el proceso de catalizador del adhesivo. Finalmente concluye con el endurecimiento del mismo, bajo la compresión ejercida por la rosca del tornillo entre el herraje y la hoja soporte en su posición definitiva de trabajo.The screw is then inserted, usually with a screwdriver, into the support sheet, and by the turning movement itself, the components are mixed, inherently promoting the catalyst process of the adhesive. Finally, it concludes with its hardening, under the compression exerted by the screw thread between the fitting and the support sheet in its final working position.
En otra realización preferente, tanto el hueco cilíndrico del interior del cuerpo principal como la cara exterior del embolo de activación están roscados; y la cara plana del extremo exterior del émbolo de activación tiene una huella de apriete angular. En esta otra realización la introducción del émbolo de activación hacia el interior del tornillo se realiza aplicando giros.In another preferred embodiment, both the cylindrical hole inside the main body and the outer face of the activation plunger are threaded; and the flat face of the outer end of the actuating plunger has an angular clamping footprint. In this other embodiment, the introduction of the activation plunger into the screw is carried out by applying twists.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
En las figuras 1 a 2 se muestra un ejemplo de realización preferente del tornillo para madera con émbolo de activación que contiene productos endurecibles. El tornillo (1) es del tipo formado por un cilindro alrededor del cual discurre una rosca de tracción helicoidal; en un extremo se ensancha para conformar la cabeza (8), donde está dispuesto un rebaje con la huella del destornillador; y en su otro extremo, es cónico y termina en punta (6).Figures 1 to 2 show a preferred embodiment of the wood screw with an activation piston containing hardenable products. The screw (1) is of the type formed by a cylinder around which a helical traction thread runs; at one end it widens to form the head (8), where a recess is arranged with the footprint of the screwdriver; and at its other end, it is conical and ends in a point (6).
Dicho tornillo (1) comprende: un cuerpo principal (5) que en su interior incorpora una elongación cilíndrica hueca, que discurre desde la cabeza (8) hasta la base cónica (9) de la punta, y que está destinada para emplazar: el componente de resina (4), el componente endurecedor (3) y el embolo de activación (2).Said screw (1) comprises: a main body (5) which inside incorporates a hollow cylindrical elongation, which runs from the head (8) to the conical base (9) of the tip, and which is intended to place: the resin component (4), hardener component (3) and activation plunger (2).
En particular, el cuerpo principal (5) en su extremo delantero presenta al menos un orificio (7) en sus laterales, que conectan la cavidad interior cilíndrica hueca con el exterior, siendo estos de tamaño considerablemente reducido en comparación con el diámetro del tornillo. Su función consiste en encauzar el flujo de los componentes endurecibles desde el interior al exterior. In particular, the main body (5) at its front end has at least one hole (7) on its sides, which connect the hollow cylindrical interior cavity with the exterior, these being considerably reduced in size compared to the diameter of the screw. Its function is to channel the flow of hardenable components from the inside to the outside.
En la figura 3, se muestra la secuencia de activación de los componentes previa al enroscado del tornillo para madera (1) en la hoja soporte de un ejemplo de realización preferente. La cual consiste en la introducción del émbolo de activación (2) hacia el interior del tornillo con la punta del destornillador (13), figura 3.1.Figure 3 shows the activation sequence of the components prior to screwing the wood screw (1) into the support sheet of a preferred embodiment. Which consists in the introduction of the activation plunger (2) into the screw with the tip of the screwdriver (13), figure 3.1.
De esta forma se comprime el componente de resina (4) y el componente endurecedor (3) obligándolos a salir del cuerpo principal (5) al exterior por los orificios laterales (7). En esta acción mostrada en la figura 3.2, el émbolo de activación (2) queda completamente encajado en el interior del hueco cilíndrico del cuerpo principal (5), dejando libre la huella de apriete de cabeza del tornillo (8). Por los orificios laterales (7) del extremo delantero del tornillo salen las gotas de los componentes endurecibles predispuestos para ser mezclados.In this way, the resin component (4) and the hardener component (3) are compressed, forcing them to exit the main body (5) to the outside through the side holes (7). In this action shown in figure 3.2, the activation plunger (2) is completely fitted inside the cylindrical hole of the main body (5), leaving free the tightening footprint of the screw head (8). Drops of hardenable components predisposed to be mixed come out of the side holes (7) at the front end of the screw.
A continuación, se introduce el tornillo para madera (1) tal como muestra la figura 3.3, usualmente con destornillador (13) en la cara frontal (16) de la hoja soporte, y por la propia acción de enroscado se realiza la mezcla de los componentes de forma intrínseca, iniciando el proceso de catalizador del adhesivo, los componentes quedan entremezclados incluso con las fibras de madera de la hoja soporte (18). Esta operativa ofrece un aumento de la fuerza especialmente significativo y, origina la propiedad antiaflojamiento gracias a la máxima compresión ejercida entre rosca y la hoja soporte en los instantes posteriores al enroscado. Esta queda mantenida en el tiempo, dado que, el endurecimiento del adhesivo garantiza la unión fuerte y duradera entre el herraje (17) y la cara de la hoja soporte (16) por largo tiempo.Next, the wood screw (1) is inserted as shown in figure 3.3, usually with a screwdriver (13) in the front face (16) of the support sheet, and by the screwing action itself, the mixing of the components in an intrinsic way, starting the adhesive catalyst process, the components remain intermixed even with the wood fibers of the support sheet (18). This operation offers a particularly significant increase in force and, originates the anti-loosening property thanks to the maximum compression exerted between the thread and the support sheet in the moments after screwing. This is maintained over time, since the hardening of the adhesive guarantees a strong and durable bond between the fitting (17) and the face of the support sheet (16) for a long time.
En la variante de realización preferente mostrada en la figura 4, tanto el hueco cilíndrico del interior del cuerpo principal como la cara exterior del embolo de activación (2) están roscados. La cara plana del extremo exterior del émbolo de activación (2) tiene una huella de apriete angular (11). Por tanto, para comprimir y activar los componentes endurecibles, en esta realización se aplican giros al émbolo activador (2).In the preferred embodiment variant shown in Figure 4, both the cylindrical hole inside the main body and the outer face of the activation plunger (2) are threaded. The flat face of the outer end of the activation plunger (2) has an angular clamping footprint (11). Therefore, to compress and activate the curable components, in this embodiment twists are applied to the activator plunger (2).
Una vez descrita suficientemente la naturaleza de la invención, así como un ejemplo de realización preferente, se hace constar a efectos oportunos que los materiales, la forma, el tamaño y la disposición de los elementos descritos podrán ser modificados, siempre y cuando ello no suponga una alteración de las características esenciales de la invención que se reivindican a continuación. Once the nature of the invention has been sufficiently described, as well as a preferred embodiment, it is stated for appropriate purposes that the materials, shape, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential characteristics of the invention that are claimed below.
