Abstract

Sports ball cover. It is a cover for sports balls, cover that is constituted by thirty panels or faces, each of which has the shape of a rhombus (1), all of them being equal both in shape and in size, providing the ball of an optimum sphericity, as well as a more homogeneous touch, since when being inflated all its panels or faces formed by the diamonds (1) support the same pressures and experience the same convexity. The two acute angles (2) of each rhombus (1) will have an amplitude of 67.5º, while the obtuse angles have an amplitude of 112.5º before the inflation of the balloon, since after inflation and under pressure to the rhombuses, the acute angles tend towards an amplitude of 72º, and the obtuse angles towards an amplitude of 120º, giving rise to the fact that all the vertices of the balloon cover tend to 360º, that is to say, to an optimum sphericity of ball.

Description

5 CUBIERTA DE BALI:* DE USO DEPORTIVO DESCRIPCION OBJETO DE LA INVENCION La presente invencion se refiere a una cubierta de balon de uso deportivo, concretamente a la cubierta exterior que envuelve la camara 10 neumatica de un balon. El objeto de la invencion es conseguir una cubierta mas facil de fabricar y con mejores prestaciones que las utilizadas convencionalmente. 15 El campo de aplicacion de la invencion corresponde al de la industria dedicada a la fabricacion de balones de uso deportivo, y concretamente a la fase de diserio y construccion de la cubierta o "panelado" exterior de un balon. 20 ANTECEDENTES DE LA INVENCION Los balones de uso deportivo y sobre todo los de competicion, suelen estar fabricados mediante una camara neumatica de caucho que es 25 susceptible de ser inflada para conseguir la presion deseada, cuya camara obliga a la utilizacion de una capa exterior o cubierta, de un material algo flexible pero no tanto como el caucho de la camara, con el fin de limitar el volumen del balon, al tiempo que dicha cubierta mejora el tacto, el control y la resistencia del propio balon. Como es evidente, la cubierta externa que se aplica en los balones de uso deportivo, no se puede realizar en una sola pieza, ya que se producirian arrugas y abultamientos, To que originaria una irregularidad 5 tanto en el bote como a la hora de llevar a cabo el control, ya sea manual o ya sea con el pie por parte del deportista. Para evitar dichos problemas, la cubierta de los balones de uso deportivo se confecciona mediante una pluralidad de caras o paneles cosidos 10 y/o pegados entre si, cuya geometria o contorno de cada uno de ellos y su tamaiio es el apropiado para que el balon adquiera una forma To mas cercana posible a la esfericidad. Tradicionalmente, para diseiiar la cubierta externa de los 15 balones, se ha recurrido a los poligonos regulares y sus derivados. Asi, por ejemplo, el balon de voleibol es un cubo cuyas seis caras se subdividen en tres paneles longitudinales, dando como resultado un balon de dieciocho paneles o caras. 20 Ese mismo patron fue utilizado para fabricar los balones de fatbol, hasta que en los aiios 70 aparecio un balon de 32 caras o paneles, tratandose en realidad de un icosaedro que al ser truncado cambia la forma triangular de sus 20 caras por hexagonos, al tiempo que sus doce vertices se convierten en pentagonos. 25 Este diseiio de la cubierta de los balones utilizados en el fatbol, es el mas acertado, ya que tanto el numero como la forma de los paneles o caras To situan mas cerca de la forma esferica pretendida. 30 Ahora bien, ese diseiio tiene una serie de problemas e 5 10 15 inconvenientes entre los que pueden citarse los siguientes: - El numero de aristas y vertices es excesivo, ya que las 32 caras o paneles que incluye la cubierta dan lugar a 90 aristas y 60 vertices, lo que supone un notable tiempo a la hora de coser o fijar entre si los distintos paneles o caras de la cub ierta. - Los dos tipos de poligonos (hexagonos y pentagonos) que componen la cubierta externa de 32 caras correspondiente a un balon de fatbol convencional, tienen una amplitud muy diferente, ya que los hexagonos presentan una amplitud superior al 50% que la que ofrecen los pentagonos, por lo que se produce una mayor convexidad en los paneles o caras de contorno hexagonal, y cuya mayor convexidad es originada por la mayor presion que soportan. DESCRIPCION DE LA INVENCION 20 La cubierta de balon de uso deportivo objeto de la invencion ha sido concebida para resolver la problematica anteriormente expuesta, en base a una solucion sencilla pero eficaz. Mas concretamente, la cubierta de la invencion se basa en que 25 los paneles o caras que participan en la constitucion de la cubierta, serán todas ellas iguales entre si y concretamente de configuracion rombica, participando treinta paneles rombicos, todos ellos iguales entre si, frente a los treinta y dos paneles o caras que presentan las cubiertas tradicionales. Al ser iguales todos los paneles o caras de la cubierta del balon, este adquiere una mayor esfericidad, asi como un tacto mas homogeneo, ya que al ser inflado todos sus paneles o caras soportan la misma presion y experimentan identica convexidad. 5 En base a que todas las caras o paneles de la cubierta son iguales, se ye simplificado el proceso de fabricacion, pues solo hay un tipo de cara o panel, concretamente el rombo, bastando un solo molde para obtener todas las caras o paneles de la cubierta. 10 El numero de aristas y de vertices se ye tambien reducido, siendo concretamente de sesenta el numero de aristas de la cubierta de la invencion, frente a las noventa aristas de las cubiertas convencionales, mientras que el numero de vertices de la cubierta de la invencion se reduce 15 a treinta y dos, frente a los sesenta de la cubierta convencional. Es decir, el numero de aristas se ye reducido en un 33,3% y el numero de vertices se ye reducido en un 46,6%, frente a las aristas y vertices que presentan las cubiertas convencionales. 20 Por otro lado, se consigue una esfericidad y homogeneidad en el conjunto del balon al tener todos los paneles o caras el mismo tamario, y soportar con ello la misma presi6n. A ello hay que ariadir el hecho de que todos los paneles o caras tienen la misma forma, con lo que la presion se 25 distribuye de igual manera, sufriendo identica convexidad en todos ellos, todo lo cual se traduce en una mayor esfericidad que establece una mayor homogeneidad en su comportamiento, incrementada por el hecho de que sus paneles o caras tambien pesan lo mismo. 30 Por tales motivos, sea cual sea el tipo de lanzamiento, golpeo o recepcion, el deportista siempre contactard con rombos iguales en forma, tamafio, presion y curvatura, To que implica un tacto mas homogeneo. Estos aspectos son muy valorados por los deportistas, con 5 independencia del deporte de que se trate y del puesto que ocupen dentro del equipo, ofreciendose sus ventajas en los siguientes casos: - En los lanzamientos, porque la direccion del balon es fiel reflejo del movimiento impulsor, gracias a su mayor 10 esfericidad. - En los golpeos, debido a que las sensaciones que el balon transmite son siempre los mismas en cuanto a presion, tacto y deformaci6n. - En las recepciones, al ser su vuelo muy regular y previsible, 15 por To que no hard extrafios, facilitando de manera notable el trabajo de los porteros. Por ultimo decir que el balon ofrecerd siempre un mismo aspecto, desde cualquier dngulo, con To que no solamente los deportistas 20 sino tambien los espectadores, aprecian por igual todos los detalles del balon, como la rotacion y el tipo de dibujo, sin que sea necesario romper el esquema geometric° de los paneles o caras de la cubierta. Todas esas prestaciones y mejoras proporcionadas por la cubierta 25 de la invencion, se consiguen en base a un numero de caras o paneles muy parecido al que presentan las cubiertas convencionales, ya que se considera que en torno a ese numero de caras, treinta segun la cubierta de la invencion, se shim el ideal para un balon, puesto que un numero superior implica demasiadas costuras asi como un tacto mas aspero, mientras que un 30 numero muy reducido de caras conlleva una gran diferencia entre el centro y el borde de los paneles o caras, en To referente a presion, esfericidad y tacto. Tambien cabe decir que el rombo en su geometria presenta en 5 sus angulos correspondientes a la diagonal mayor con una amplitud de 67,5°, mientras que los angulos contrarios, es decir los de la diagonal menor presentaran una amplitud de 112,5°, de manera que un balon inflado con la cubierta de la invencion, da lugar a que el valor de los vertices agudos de cada angulo tienda a ampliarse hasta los 72°, mientras que la 10 amplitud de los angulos obtusos tiende a ampliarse hasta los 120°, tendiendo logicamente todos sus vertices a los 360°, debido a la expansion que produce la presi6n interior. 15 DESCRIPCION DE LOS DIBUJOS Para complementar la descripcion que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensi6n de las caracteristicas del invento, de acuerdo con un ejemplo preferente de 20 realizacion practica del mismo, se acompaiia como parte integrante de dicha descripcion, un juego de dibujos en donde con caracter ilustrativo y no limitativo, se ha representado To siguiente: La figura 1.- Muestra una representacion correspondiente al 25 desarrollo de To que seria la cubierta del balon de uso deportivo, formada mediante treinta rombos iguales. La figura 2.- Muestra la forma concreta del rombo que participa como base o panel en la constitucion de la cubierta de la invencion, 30 viendose concretamente los grados de los angulos agudos y de los angulos obtusos de dicho rombo. La figura 3.- Muestra una vista tridimensional del poliedro que forman los treinta rombos que participan en la constitucion de la cubierta 5 objeto de la invencion, sin llegar a estar totalmente expandida. 10 La figura 4.- Muestra una vista en perspectiva de la configuracion de un balon con la cubierta de la invencion, totalmente inflado. REALIZACION PREFERENTE DE LA INVENCION Como se puede ver en las figuras referidas, la cubierta para un 15 balon de uso deportivo, como puede ser el utilizado en el fatbol, incluye treinta caras o paneles (1), de configuracion rombica, en donde sus angulos agudos (2) presentan preferentemente una amplitud de 67,5°, mientras que los angulos obtusos (3) presentan una amplitud de 112,5°, de manera tal que cuando la cubierta se aplica sobre la camara de caucho del balon y se 20 infla este, adquiere la configuracion mostrada en la figura 4, los angulos agudos (2) de los rombos (1) tienden a ampliarse hasta los 72°, mientras que los angulos obtusos (3) de dichos rombos tienden a ampliarse hasta los 120°, debido a la presion que produce la expansion interior cuando se infla el balon. 25 En la figura 4 se dejan ver las aristas (4) que determinan la union entre si, bien sea mediante cosido o mediante pegado, de los distintos rombos (1) que han de constituir la cubierta, de manera que el numero de aristas (4) es concretamente de sesenta, y el numero de vertices (5) es de treinta y dos, frente a las noventa y sesenta, respectivamente, que incluyen las cubiertas de los balones convencionales. En la figura 3 se deja ver ademas como en la imagen 5 tridimensional del poliedro que forman los treinta rombos (1), los angulos agudos convergen en un vertice de cinco caras, en tanto que los angulos obtusos convergen en un vertice de tres caras, de manera que en cualquier caso la suma de los valores angulares de cualquier vertice es de 337,50, mientras que en la figura 4, con el balon ya inflado y la tendencia a 10 ampliarse de los angulos agudos y obtusos, da lugar a que los vertices tiendan a los 360°, determinando una Optima esfericidad del balon. FIG. 2 FIG. 2 5 BALI COVER: * OF SPORTS USE DESCRIPTION OF THE INVENTION The present invention relates to a ball cover for sports use, specifically to the outer cover that surrounds the pneumatic chamber 10 of a ball. The object of the invention is to achieve a cover easier to manufacture and with better performance than conventionally used. The field of application of the invention corresponds to that of the industry dedicated to the manufacture of balls for sports use, and specifically to the design phase and construction of the outer covering or "paneling" of a ball. BACKGROUND OF THE INVENTION Balls for sporting use, and above all competition balls, are usually manufactured by means of a pneumatic rubber chamber that is capable of being inflated to achieve the desired pressure, whose chamber requires the use of an outer layer or cover, of a somewhat flexible material but not as much as the rubber of the camera, in order to limit the volume of the ball, while said cover improves the feel, control and resistance of the ball itself.    As it is evident, the external cover that is applied in the sports balls, can not be made in a single piece, as it would produce wrinkles and bulges, To which originates an irregularity 5 both in the boat and when carrying out the control, either manual or with the foot on the part of the athlete. To avoid such problems, the cover of the balls for sports use is made by a plurality of faces or panels sewn 10 and / or glued together, whose geometry or contour of each of them and its size is appropriate for the ball acquire a shape as close as possible to the sphericity. Traditionally, to design the outer cover of the 15 balls, regular polygons and their derivatives have been used. Thus, for example, the volleyball is a cube whose six faces are subdivided into three longitudinal panels, resulting in a ball of eighteen panels or faces. 20 This same pattern was used to make the soccer balls, until in the 70's a 32-sided balloon or panels appeared, in fact it is an icosahedron that, when truncated, changes the triangular shape of its 20 faces into hexagons, time that its twelve vertices become pentagons. 25 This design of the cover of the balls used in the football, is the most successful, since both the number and the shape of the panels or faces To locate closer to the intended spherical shape. 30 Now, that design has a series of problems and 5 10 15 disadvantages among which the following can be mentioned: - The number of edges and vertices is excessive, since the 32 faces or panels that the cover includes give rise to 90 edges and 60 vertices, which means a considerable time to the time to sew or fix the different panels or faces of the cube together. - The two types of polygons (hexagons and pentagons) that make up the 32-sided outer shell corresponding to a conventional fatbol ball, have a very different amplitude, since the hexagons have an amplitude greater than 50% than that offered by the pentagons , so there is a greater convexity in the panels or hexagonal contour faces, and whose greater convexity is caused by the higher pressure they support. DESCRIPTION OF THE INVENTION The sports ball cover object of the invention has been conceived to solve the aforementioned problem, based on a simple but effective solution. More specifically, the cover of the invention is based on the fact that the panels or faces that participate in the constitution of the roof will all be equal to each other and specifically of a rhombic configuration, with thirty rhombic panels participating, all of them equal to each other, facing each other. to the thirty-two panels or faces that present the traditional covers.    Since all the panels or faces of the balloon cover are the same, it acquires a greater sphericity, as well as a more homogeneous touch, since when inflated all its panels or faces support the same pressure and experience identical convexity. 5 On the basis that all the faces or panels of the cover are equal, the manufacturing process is simplified, since there is only one type of face or panel, specifically the diamond, with just one mold sufficient to obtain all the faces or panels of the cover. The number of edges and vertices is also reduced, being specifically sixty the number of edges of the cover of the invention, compared to the ninety edges of the conventional covers, while the number of vertices of the cover of the invention. it reduces from 15 to thirty-two, compared to sixty of the conventional cover. That is, the number of edges is reduced by 33.3% and the number of vertices is reduced by 46.6%, compared to the edges and vertices that conventional covers have. On the other hand, a sphericity and homogeneity is achieved in the whole balloon by having all the panels or faces the same size, and withstand the same pressure with it. To this must be added the fact that all the panels or faces have the same shape, with which the pressure is distributed in the same way, suffering identical convexity in all of them, all of which translates into a greater sphericity that establishes a greater homogeneity in their behavior, increased by the fact that their panels or faces also weigh the same. 30 For such reasons, whatever the type of launch, hit or    reception, the athlete always contact with equal diamonds in shape, size, pressure and curvature, which implies a more homogenous touch. These aspects are highly valued by athletes, with independence from the sport in question and the position they occupy within the team, offering their advantages in the following cases: - In the throws, because the direction of the ball is a true reflection of the movement impeller, thanks to its greater sphericity. - In the hits, because the sensations that the ball transmits are always the same in terms of pressure, touch and deformation. - In the receptions, since your flight is very regular and predictable, 15 so that you do not have any problems, making the work of the porters much easier. Finally, to say that the ball always offers the same aspect, from any angle, with the fact that not only the athletes 20 but also the spectators, appreciate equally all the details of the ball, such as the rotation and the type of drawing, without being It is necessary to break the geometric pattern of the panels or faces of the roof. All those features and improvements provided by the cover 25 of the invention, are achieved based on a number of faces or panels very similar to that presented by conventional covers, since it is considered that around that number of faces, thirty according to the cover of the invention, shim is ideal for a ball, since a higher number implies too many seams as well as a rougher touch, while a very small number of faces entails a large difference between the center    and the edge of the panels or faces, in To relating to pressure, sphericity and touch. It can also be said that the rhombus in its geometry presents in 5 its angles corresponding to the greater diagonal with an amplitude of 67.5 °, while the opposite angles, that is to say those in the smaller diagonal, have an amplitude of 112.5 °, so that a balloon inflated with the cover of the invention, results in the value of the acute vertices of each angle tending to expand up to 72 °, while the amplitude of the obtuse angles tends to be extended up to 120 ° , logically extending all its vertices to 360 °, due to the expansion produced by the internal pressure. DESCRIPTION OF THE DRAWINGS To complement the description that will be made below and in order to help a better understanding of the characteristics of the invention, according to a preferred example of a practical embodiment thereof, it is included as an integral part of said description. description, a set of drawings in which, with illustrative and non-limiting character, the following is represented: Figure 1.- Shows a representation corresponding to the development of To which would be the cover of the ball for sporting use, formed by thirty equal diamonds . Figure 2 shows the concrete shape of the rhombus that participates as a base or panel in the constitution of the cover of the invention, 30 specifically seeing the degrees of acute angles and angles  obtuse of said diamond. Figure 3 shows a three-dimensional view of the polyhedron formed by the thirty diamonds that participate in the constitution of the cover 5 object of the invention, without being fully expanded. Figure 4 shows a perspective view of the configuration of a balloon with the cover of the invention, fully inflated. PREFERRED EMBODIMENT OF THE INVENTION As can be seen in the referenced figures, the cover for a ball for sports use, such as that used in football, includes thirty faces or panels (1), of a rombic configuration, where their angles Treants (2) preferably have an amplitude of 67.5 °, while obtuse angles (3) have an amplitude of 112.5 °, such that when the cover is applied on the rubber chamber of the balloon and inflates this, acquires the configuration shown in figure 4, the acute angles (2) of the diamonds (1) tend to expand up to 72 °, while the obtuse angles (3) of these diamonds tend to expand to 120 ° , due to the pressure produced by the internal expansion when the ball is inflated. 25 Figure 4 shows the edges (4) that determine the union between them, either by stitching or by gluing, the different diamonds (1) that have to constitute the cover, so that the number of edges ( 4) is specifically sixty, and the number of vertices (5) is    thirty-two, compared to ninety and sixty, respectively, which include the covers of conventional balloons. In figure 3 it can also be seen as in the three-dimensional image of the polyhedron forming the thirty diamonds (1), the acute angles converge on a five-sided vertex, while the obtuse angles converge on a three-sided vertex, so that in any case the sum of the angular values of any vertex is 337.50, while in figure 4, with the balloon already inflated and the tendency to 10 expand from the acute and obtuse angles, it results in the vertices tend to 360 °, determining an optimal sphericity of the ball.
