Abstract

La présente invention concerne un dispositif d'entraînement au tennis permettant à un utilisateur de s'entraîner de façon répétée à la frappe d'une balle de tennis. Par le dispositif d'entraînement au tennis, selon la présente invention, un point de réglage peut être placé sur la gauche et sur la droite d'un endroit souhaité pour limiter le déplacement d'un point de fixation le long d'une corde. Par conséquent, lorsqu'une balle frappée revient en raison d'une force de répulsion après avoir entraîné le point de fixation vers la direction dans laquelle la balle frappée se déplace, la balle frappée rebondit au point de fixation ayant coulissé entre les points de réglage puis revient à proximité d'un utilisateur. Le dispositif d'entraînement au tennis comporte un joint annulaire, une bague en 8, et une poulie rotative reliée à cette dernière de sorte que la corde ne subisse pratiquement aucune torsion, comprend un contenant de rangement (une boîte à balles) et est ainsi facilement rangé et transporté dans ce dernier de sorte que le dispositif d'entraînement au tennis puisse être facilement et fréquemment rangé dans le contenant de rangement et en être sorti, et permet à un utilisateur de s'entraîner de manière agréable à la frappe d'une balle de tennis même dans un petit espace.
