Abstract

Procedure for obtaining a paddle paddle and blade obtained. In known processes, once the blade is obtained from the mold, it is drilled into the striking surfaces and the core to obtain the regulatory holes. This process weakens the structure constituted by the tissues of the blade impregnated with the epoxy resin, therefore its resistance. The invention consists of pre-cutting the core and the layers of the tissues used to manufacture the core and both striking surfaces of the blade, so that rounded lugs are established on the surfaces of the mold to guide said tissues (3) through its holes, and once the resin has cured, it is not subjected to any type of process that could break and weaken its structure. This process makes it possible to obtain holes with a rounded edge instead of a 45º sharp one, improving the resistance, aerodynamics and aesthetics of the blade.

Description

DESCRIPCIÓNDESCRIPTION

Procedimiento de obtención de una pala de pádel y pala obtenidaProcedure for obtaining a padel racket and racket obtained

SECTOR DE LA TÉCNICATECHNICAL SECTOR

La presente invención se refiere a un procedimiento de obtención de una pala de pádel, que presenta la particularidad de que los taladros pasantes que presenta este tipo de palas en su zona de golpeo se llevan a cabo mediante un proceso completamente distinto, de manera que los habituales orificios se hacen antes de fabricar la pala en sus materiales y las embocaduras de entrada y salida de dichos orificios presentan un borde redondeado, mejorando así la aerodinámica y sobretodo la resistencia de la pala.The present invention refers to a procedure for obtaining a paddle paddle, which has the particularity that the through holes that this type of paddle has in its striking area are carried out by means of a completely different process, so that the usual holes are made before manufacturing the blade in its materials and the entry and exit mouths of said holes have a rounded edge, thus improving the aerodynamics and above all the resistance of the blade.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Como es sabido, una pala de pádel se obtiene mediante moldeo de unas capas de tejidos con resina epoxi y un núcleo de gomaespuma intercalado entre los anteriores, complementándose con el correspondiente marco que se remata en el asa o mango de agarre manual de la pala.As is known, a paddle tennis racket is obtained by molding some layers of fabrics with epoxy resin and a foam rubber core sandwiched between the previous ones, complemented by the corresponding frame that is finished off in the handle or manual grip of the racket.

En el proceso tradicional, después de obtener el moldeado y conformación de la pala, la misma se somete a un proceso de taladrado, en orden a obtener los orificios pasantes obligatorios por reglamento, que permiten el paso del aire y reducen la fricción con éste.In the traditional process, after obtaining the molding and shaping of the blade, it is subjected to a drilling process, in order to obtain the through holes required by regulation, which allow the passage of air and reduce friction with it.

Este proceso de taladrado lleva consigo el debilitamiento de los tejidos o materiales utilizados en las superficies de golpeo, afectando a su resistencia, además de presentar unas aristas vivas, que no resultan óptimas desde un punto de vista aerodinámico. Por ello, para que soporten y sean resistentes al impacto de la bola debe incrementarse la cantidad de material a utilizar incrementando el peso de la pala. This drilling process leads to the weakening of the fabrics or materials used in the striking surfaces, affecting their resistance, in addition to presenting sharp edges, which are not optimal from an aerodynamic point of view. Therefore, in order to support and be resistant to the impact of the ball, the amount of material to be used must be increased by increasing the weight of the blade.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El procedimiento que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una solución más compleja en cuanto a diseño, desarrollo y la fabricación, pero eficaz.The procedure that is recommended solves in a fully satisfactory way the problems previously exposed, based on a more complex solution in terms of design, development and manufacture, but effective.

Para ello, y de forma más concreta, las dos tapas que participan en el molde, están dotadas de tetones redondeados que van a originar los correspondientes orificios en ambas superficies de golpeo, obtenidas a base de tejidos empapados en resina epoxi, de manera que, previamente a la adición de la resina epoxi, tanto los tejidos que participan en dichas capas externas, como el núcleo han sido previamente pre cortados con los orificios oportunos.For this, and more specifically, the two lids that participate in the mold are equipped with rounded lugs that will create the corresponding holes in both striking surfaces, obtained from fabrics soaked in epoxy resin, so that, Before adding the epoxy resin, both the fabrics that participate in said outer layers, as well as the core, have been previously pre-cut with the appropriate holes.

De esta forma, al verter la resina sobre los moldes, esta rodeará los citados tetones, empapándose en las tejidos pre cortados, y formando así unos orificios en su curado mucho más fuertes y resistentes, formando además con una embocadura o arista redondeada, que mejora a su vez la aerodinámica de la pala, viéndose en cualquier caso incrementada su resistencia, al no verse comprometida por herramientas de taladrado una vez curada la resina.In this way, when pouring the resin on the molds, it will surround the aforementioned pegs, soaking in the pre-cut fabrics, and thus forming much stronger and more resistant holes during its curing, also forming a rounded mouth or edge, which improves at the same time, the aerodynamics of the blade, its resistance being increased in any case, as it is not compromised by drilling tools once the resin has cured.

Además, el obtener orificios de arista redondeada en base a la configuración de los tetones de las tapas del molde, es posible reducir el número de capas de tejidos de diferentes materiales para obtener las prestaciones y resistencias habituales requeridas en una pala de pádel, consiguiéndose con ello una reducción del peso de la pala.In addition, by obtaining rounded edge holes based on the configuration of the lugs of the mold covers, it is possible to reduce the number of layers of fabrics of different materials to obtain the usual performance and resistance required in a paddle tennis racket, achieving with This reduces the weight of the blade.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, puede observarse como el procedimiento de la invención consiste en un proceso de moldeo por curado de resina epoxi, en el que participa un molde formado por dos mitades o tapas simétricas, con la forma de la pala a obtener, en los que se establece una superficie plana (1-1) determinante de las superficies de golpeo, con la particularidad de que dichas superficies planas (1) están afectadas de una pluralidad de tetones (2) redondeados, tal y como se representa en el detalle de la figura 2, de manera tal que, sobre ambas tapas se introducen los tejidos (3) que van a formar la superficie de golpeo, y que son impregnados en resina epoxi, y que están previamente pre cortados, con orificios (4) guiados en los tetones (2) de las tapas del molde, tal como muestra la figura (6).In view of the outlined figures, it can be seen how the process of the invention consists of a molding process by curing epoxy resin, in which a mold formed by two halves or symmetrical caps participates, with the shape of the blade to be obtained. , in which a flat surface (1-1) determining the striking surfaces is established, with the particularity that said flat surfaces (1) are affected by a plurality of rounded lugs (2), as represented in the detail of figure 2, in such a way that, on both covers, the tissues (3) that will form the surface of the beating, and which are impregnated with epoxy resin, and which are previously pre-cut, with holes (4) guided in the lugs (2) of the mold covers, as shown in figure (6).

Sobre dichos tejidos (3) impregnados en resina epoxi, concretamente sobre una de las dos tapas del molde, de acuerdo con la figura 7, se dispone el núcleo (5), también pre cortado, con orificios (6) pasantes, para a continuación colocar el correspondiente marco (7), tal como se muestra en la figura 8, para cerrar una tapa contra otra, habiendo puesto en la segunda tapa también los tejidos impregnados en resina epoxi, sometiéndose a un proceso de prensado y cocinado o curado de la resina.On said fabrics (3) impregnated in epoxy resin, specifically on one of the two covers of the mold, according to figure 7, the core (5) is arranged, also pre-cut, with through holes (6), to then place the corresponding frame (7), as shown in figure 8, to close one lid against another, having also placed the fabrics impregnated in epoxy resin on the second lid, undergoing a process of pressing and cooking or curing of the resin.

Una vez curada la resina se procede al desmoldeo de la pala, obteniéndose así una pala de pádel ya agujereada, en donde sus orificios presentan una arista redondeada, mucho más estética, y lo más importante resistente, al no verse afectada su estructura a base de resina por ninguna herramienta de corte, en contra de lo que sucede tradicionalmente. Once the resin has cured, the blade is removed from the mold, thus obtaining a paddle blade that is already drilled, where its holes have a rounded edge, much more aesthetic, and most importantly resistant, as its structure based on resin by no cutting tool, contrary to what happens traditionally.
