Definitions

  • This application for a utility model patent refers to an unprecedented device with a flexible double rod to be installed on the racket strings for sports practice, especially for tennis, which, due to the interconnection of the double rod in a cylindrical central body, transversely creased, promotes perfect fixation to the strings, as well as prevents its unexpected detachment during a game, thus avoiding a drop in performance and / or loss of the innovated device.
  • the aforementioned device has as main drawbacks, the difficult handling and / or positioning on the racket strings, making it almost impossible to adjust during the match and, like the first anteriority, it does not have a mechanism for fixing the racket.
  • WO 2017/009699 entitled “Vibration Dampening Devicesand System” refers to a cushioning device to be used in tennis racket strings, which has a fastening element represented by a flap with a male fitting and another flap with female insert, forming a “C” clamp capable of covering up to two strings of the racket.
  • the aforementioned device despite having a male and female type fastening element, still has some technical limitations due to its “C” clamp shape and the unique fastening element.
  • the clamp shape tends to exert a force in order to open the device, due to the mass of material concentrated in the curvature of the clamp.
  • the span for insertion of the strings is free, which means that the movement of the strings within it is not limited, which enhances the impacts and their effects against the closure system, which may collapse it.
  • the aim of this innovation is to propose an anti-vibration device that delimits and distributes, on two different sides, the impact and consequent vibration caused by the ball on the strings of the racket, in addition to preventing its unexpected decoupling during the tennis match.
  • the aim of this innovation is to propose an anti-vibration device capable of dampening as much as possible the impact of the ball on the strings of the tennis racket during the match.
  • the aim of this innovation is to propose an anti-vibration device that, due to all the above characteristics, helps to increase the player's performance.
  • the objective of this innovation is to propose an anti-vibration device with an excellent cost-benefit ratio.
  • the “DOUBLE ROD ROD DEVICE FOR SPORT RACKET STRINGS” consists of a device for direct use on the strings of the tennis racket, with the aim of reducing the vibration on the strings when the ball hits, the disposition of which constructive features two flexible rods that, when bending, are fixed in a non-definitive way, with a male and female type fitting, in a central body vertically hollow and transversely creased in the direction of the racket strings, where such a device will be positioned.
  • the device with two rods and the creased central body promotes the much more effective accommodation of two strings of the racket, which take place between the crease and the rods that, folded over themselves, enclose them, thus better delimiting the ropes travel on each side of the body, better distributing the result of the impact on the device.

Abstract

L'invention concerne un dispositif (1) robuste, doté de deux tiges unifilaires souples (2 et 3) qui se plient et se fixent, de manière non définitive, sur un corps central (4) cylindrique, évidé (5) verticalement et plié (6) transversalement, lequel délimite le trajet de deux cordes (CV) verticales de la raquette (7), entre le corps central (4) à proprement parler et lesdites tiges (2 et 3), distribuant ainsi de façon améliorée l'effet de l'impact de la balle sur le dispositif (1) et évitent son désaccouplement intempestif de la raquette (7).
