RACCHETTA DA TENNIS PARABOLICA PARABOLIC TENNIS RACKET

RIASSUNTO SUMMARY

L ' essenza dell ' invenzione sta nella possibilità di ottenere , mediante un metodo nuovo ed originale di accordatura ) come meglio esplicato nelle tavole coi disegni allegati n . 1 /2/3/4 , due piani non piu' piatti come finora esistenti , ma concavi , a forma di cucchiaio , in entrambe le facce di battuta della racchetta stessa . L ' attuale stato della tecnica prevede infatti una serie di fori sul supporto della racchetta terminanti all ' interno dello stesso tutti su una stessa linea , passando attraverso i quali le corde , incrociandosi verticalmente ed orizzontalmente formano un piano di battuta piatto da ambo i lati . The essence of the invention lies in the possibility of obtaining, by means of a new and original method of tuning) as better explained in the tables with the attached drawings n. 1/2/3/4, two planes no longer flat as existed up to now, but concave, in the shape of a spoon, on both sides of the racquet itself. The current state of the art in fact provides for a series of holes on the racket support ending inside it all on the same line, passing through which the strings, crossing vertically and horizontally, form a flat striking surface on both sides.

DESCRIZIONE DESCRIPTION

Nella racchetta da tennis parabolica invece si debs bono eseguire due serie di fori paralleli ai bordi del supporto e passanti in modo verticale cosi da ottenere all'interno del supporto stesso altre due serie di fori paralleli attraverso i quali le corde dovranno passare in maniera orizzontale e verticale o in qualsiasi altro modo(obliquamente ecc .),purché parten do da un foro in alto da una parte si finisca col passare in un foro in basso dalla parte opposta e vicevere sa e cosi ' via . Ripetendo fino al completamento del disegno l'operazione sopracitata ,le corde, incrociandosi tra loro , formeranno due piani di battuta non piu ' piatti ma concavi da entrambi i lati della racchetta.Con tale procedimento si ottiene quindi una sorta di doppia accordatura con maggiore elasticità e maggiore piano d'appoggio per la pallina ,minore durezza per il braccio del giocatore ed una notevole possibi ità di variare i colpi. In the parabolic tennis racket, on the other hand, it is necessary to make two series of holes parallel to the edges of the support and passing vertically so as to obtain inside the support itself two other series of parallel holes through which the strings must pass horizontally and vertical or in any other way (obliquely, etc.), as long as starting from a hole at the top on one side you end up passing through a hole at the bottom on the opposite side and vice versa and so on. By repeating the aforementioned operation until the drawing is complete, the strings, crossing each other, will form two striking planes that are no longer flat but concave on both sides of the racket. and greater support surface for the ball, less hardness for the player's arm and a considerable possibility of varying the strokes.
