Abstract

Raqueta que lleva órganos hidráulicos o hidroneumáticos de reglaje y de distribución de la tensión del cordaje caracterizada porque lleva un bastidor provisto de una ranura periférica sobre la cual se aplica una envoltura deformable por medio de la presión de un fluido interno, que lleva una serie de piezas alargadas aplicadas externamente sobre la envoltura deformable y que sirven de apoyo para el cordaje, llevando estas piezas alargadas aletas que están destinadas a encajarse en aberturas dispuestas en el bastidor y que están provistas de canales para el paso de cuerdas, y por el hecho de que por lo menos un tubo ligero lleno de líquido incompresible constituye la envoltura deformable estando acoplado a un dispositivo hidráulico o hidroneumático de regulación de presión localizado en el mango de la raqueta, y que puede ser maniobras por el usuario para el reglaje de la tensión del cordaje, llevando este dispositivo además en sí un elemento elástico especialmente destinado a reaccionar,en el sentido de un amortiguamiento, y de una elasticidad, ante las bruscas variaciones de tensiones del cordaje ejercidas sobre las piezas alargadas en el momento del choque de una pelota.
