Abstract
LA PRESENTE INVENTION CONCERNE UN CADRE DE RAQUETTE DONT LE PERIMETRE INTERIEUR PRESENTE DES SURFACES PLANES DISPOSEES SYMETRIQUEMENT PAR RAPPORT A UN AXE VIRTUEL PASSANT PAR LE CENTRE. CETTE DISPOSITION PERMET D'OBTENIR UNE TENSION UNIFORME ET UNE LONGUEUR EGALE DES CORDES. LE POURCENTAGE DE SURFACE D'IMPACT IDEALE AU MOMENT DE LA FRAPPE EST PLUS IMPORTANTE QUE DANS LES RAQUETTES CLASSIQUES ET LA REACTION DES CORDES DANS CETTE SURFACE PLUS UNIFORME. CETTE INVENTION PEUT S'APPLIQUER AUX RAQUETTES UTILISEES DANS LES JEUX DE BALLES TELS QUE TENNIS, SQUASH, BADMINGTON.
