Abstract

L'invention concerne un poids (5D) destiné à une raquette. Un tel poids est monté amovible sur un raccord (4) ou de manière adjacente à celui-ci, entre un grip (2) et une surface (3) de la raquette (1) et permet à l'utilisateur de se muscler pendant la frappe des balles ou l'exécution de coups d'entraînement. Le poids (5D) est conçu dans un matériau en résine élastique ou dans un matériau amortisseur, se présente sous la forme d'un anneau épais, plat et élastique et est constitué, au niveau de la paroi interne, d'une partie concavo-convexe (A) adaptée à la forme externe de la région de montage de la raquette (1). De plus, des éléments de remplissage ou des éléments de poids (8) conçus dans un matériau à gravité élevée spécifique sont intégrés ou incorporés ou à moitié incorporés dans des positions symétriques par rapport à la ligne centrale transversale ou longitudinale de la partie épaisse. Des poids égaux sont ajoutés sur les côtés avant et arrière et/ou droite et gauche de la raquette (1) ou de la surface de la raquette (3) dans la région de montage.
