Description

DESCRIPCIÓN DESCRIPTION
Sistema regulador de la altura de la red para deportes de raqueta Net height adjustment system for racquet sports
Campo de la invención Field of the invention
La presente invención se refiere a un sistema regulador de la altura de la red para deportes de raqueta, de especial aplicación en la práctica del tenis y del pádel y para la práctica de actividades de entrenamiento y juego. The present invention refers to a system for regulating the height of the net for racquet sports, of special application in the practice of tennis and paddle tennis and for the practice of training and game activities.
Antecedentes de la invención Background of the invention
Las normas oficiales para el deporte del tenis (entre otras, la normativa sobre instalaciones deportivas y de esparcimiento, normas NIDE del Consejo Superior de Deportes), establecen que la red debe estar en el apoyo de los postes a una altura fija de 1 .07 m, y en el centro a una altura de 0.914 m. Estas alturas se consiguen gracias a la tensión aportada al cable de red mediante un mecanismo tensor que debe existir en uno de los postes, y una cinta vertical situada en el centro de la red, llamada faja o corbata, que sujeta la red al pavimento para ajustar la altura necesaria. Estas alturas son válidas tanto para el juego individual como de dobles. Además, para la práctica del tenis en niños, la altura en los extremos de la red es la misma que en adultos, variando la altura en el centro mediante la regulación de la faja y la tensión del cable de la red. The official regulations for the sport of tennis (among others, the regulations on sports and leisure facilities, NIDE regulations of the Higher Sports Council), establish that the net must be supported by the posts at a fixed height of 1 .07 m, and in the center at a height of 0.914 m. These heights are achieved thanks to the tension provided to the network cable by means of a tensioning mechanism that must exist in one of the posts, and a vertical tape located in the center of the network, called a girdle or tie, which holds the network to the pavement to adjust the necessary height. These heights are valid for both singles and doubles. In addition, for the practice of tennis in children, the height at the ends of the net is the same as in adults, varying the height in the center by regulating the belt and the tension of the net cable.
La altura fija reglamentaria de la red de 1.07 m en el apoyo de los postes, para todos los casos, ha conllevado que los postes se fabriquen específicamente para dicha altura, sin posibilidad de regulación de la red en altura en dicho apoyo de los postes. The fixed regulatory height of the net of 1.07 m in the support of the posts, for all cases, has meant that the posts are manufactured specifically for said height, without the possibility of adjusting the height of the net in said support of the posts.
Para el deporte del pádel, la situación es similar, siendo la altura de la red en los postes de 0.92 m y en el centro de 0.88 m. For the sport of paddle tennis, the situation is similar, being the height of the net at the posts of 0.92 m and in the center of 0.88 m.
Sin embargo, para ciertas actividades de entrenamiento y juego, tanto para edades infantiles como adultas, se considera importante poder contar con un sistema que permita la regulación de la altura de la red, tanto en el apoyo de los postes como en el centro de la red. However, for certain training and play activities, both for children ages As adults, it is considered important to be able to have a system that allows regulation of the height of the net, both in the support of the posts and in the center of the net.
También resulta importante que el sistema permita realizar otro tipo de ejercicios específicos que mejoran la precisión, como, por ejemplo, ejercicios de paso de la bola a cierta altura de la red o por zonas específicas de la red. It is also important that the system allows other types of specific exercises that improve precision, such as exercises to pass the ball at a certain height of the net or through specific areas of the net.
Tradicionalmente estas modificaciones se han llevado a cabo de forma artesanal. Por ejemplo, modificando únicamente la altura en el centro de la red, o atando palos a los postes mediante cuerdas para conseguir un suplemento vertical y colocando una cuerda o cinta en los extremos de los suplementos verticales, de modo que el jugador intente pasar la pelota entre la parte superior de la red y la cuerda o cinta. Sin embargo, en ambos casos los resultados no son plenamente satisfactorios. Traditionally these modifications have been carried out in an artisanal way. For example, modifying only the height in the center of the net, or tying sticks to the posts with ropes to achieve a vertical supplement and placing a rope or ribbon at the ends of the vertical supplements, so that the player tries to pass the ball between the top of the net and the rope or ribbon. However, in both cases the results are not fully satisfactory.
Se han desarrollado otros sistemas que permiten la extensión en altura de la red empleada en la práctica del tenis u otros deportes de raqueta. El documento US 4852876 A, referido a un “Extensor de la altura de una red de tenis”, describe un extensor adaptado para ser utilizado con una red de tenis reglamentaria y con postes para red de tenis situados en una cancha de tenis. Incluye un par de postes auxiliares para red de tenis, teniendo cada uno de ellos al menos una ranura abierta que se extiende desde un extremo inferior de los postes auxiliares para red de tenis para permitir que pase una cuerda unida a la red de tenis. Los postes auxiliares para red de tenis se pueden fijar a los postes de tenis de manera liberable de forma que se extiendan por encima de ellos. Una red auxiliar de tenis con un borde longitudinal superior y un borde longitudinal inferior tiene su borde longitudinal superior sujeto a los postes auxiliares para red de tenis, de forma que su borde inferior se superpone a un borde superior de la red de tenis cuando los postes auxiliares para red de tenis están unidos a los postes para red de tenis. Other systems have been developed that allow the height extension of the net used in the practice of tennis or other racquet sports. US 4852876 A, referring to a "Tennis Net Height Extender", describes an extender adapted to be used with a regulation tennis net and with posts for a tennis net located on a tennis court. It includes a pair of auxiliary tennis net posts, each having at least one open slot extending from a lower end of the auxiliary tennis net posts to allow a rope attached to the tennis net to pass. The tennis net auxiliary posts can be releasably attached to the tennis posts so that they extend above them. An auxiliary tennis net with an upper longitudinal edge and a lower longitudinal edge has its upper longitudinal edge attached to the auxiliary tennis net posts so that its lower edge overlaps an upper edge of the tennis net when the posts Tennis net aids are attached to the tennis net posts.
El documento FR 2995794 A1 hace referencia a un sistema de postes para voleibol, cuyos postes disponen de una ranura y de una pieza móvil que se desplaza por la mencionada ranura.
