For the purpose of deflecting the string, the radially outer openings of the covering sleeves 11 and 12 are each rounded.

Abstract

Cette raquette pour jeux de balle, en particulier raquette de tennis, de squash ou de badminton, comprend une tête avec une surface de frappe reliée à un manche avec une poignée. La surface de frappe est définie par au moins une corde tendue en croix qui à cet effet traverse des trous radiaux dans la cadre qui délimite la tête de la raquette, en particulier au moyen d'une bande de rivetage intermédiaire (10) qui comprend des douilles (11, 12) que l'on peut placer dans les trous du cadre de la tête de la raquette. Lorsque l'on tend la ou les cordes, celles-ci passent sur des sections extérieures (13, 13') dans le sens radial situées entre deux trous (17 ou 18) ou douilles (11, 12) adjacents dans la direction de la circonférence du cadre (16) de la tête de la raquette ou de la bande de rivetage (10). Au moins dans une partie du cadre de la tête de la raquette et/ou de la bande de rivetage (10), ces sections extérieures (13, 13') comprennent chacune au moins deux moulures de hauteurs différentes (14, 15 ou 14', 15') qui dévient alternativement la ou les cordes.
