CORDAS DE RAQUETES ESPORTIVAS SPORTING RACKET STRINGS
Introdução Introduction
[001 ] Refere-se o presente pedido de patente de modelo de utilidade, a um inédito dispositivo com dupla haste flexível a ser instalado nas cordas de raquetes para prática esportiva, em especial para jogo de ténis que, devido a interligação da dupla haste em um corpo central cilíndrico vincado transversalmente, promove perfeita fixação às cordas, bem como evita o seu desprendimento inesperado durante uma partida, evitando assim queda de performance e/ou perda do dispositivo inovado. [001] 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.
Campo de aplicação Application field
[002] A inovação é aplicada no segmento de artigos esportivos, mais especificamente àquele voltado a prática de ténis de quadra. [002] Innovation is applied to the sporting goods segment, more specifically to the one aimed at playing tennis.
Estado da técnica State of the art
[003] Durante uma partida de ténis é comum a utilização de dispositivos para a redução das vibrações que as bolas causam nas cordas da raquete, natural dos golpes inerentes ao jogo, potencializadas pelos jogos de alta performance e/ou lances mal executados. [003] During a tennis match, it is common to use devices to reduce the vibrations caused by the balls in the racket strings, natural to the strokes inherent in the game, enhanced by high performance games and / or poorly executed moves.
[004] O atual estado da técnica antecipa inúmeros documentos de patentes que versam sobre estes dispositivos antivibradores, como o US 5538244 intitulado “Vibration Absorption Device”, que trata de um bloco prismático retangular em material visco elástico, dotado de várias ranhuras que se encaixam numa pluralidade de cordas da raquete, tanto no sentido longitudinal quanto no transversal. [004] The current state of the art anticipates numerous patent documents dealing with these anti-vibration devices, such as US 5538244 entitled "Vibration Absorption Device", which deals with a rectangular prismatic block in visco-elastic material, equipped with several grooves that fit together in a plurality of racket strings, both in the longitudinal and in the transverse direction.
[005] A solução acima, enquanto bem encaixada às cordas da raquete, desempenha bem a sua função antivibracional, no entanto, no decorrer da partida, com os impactos da bola, tende a se soltar levando o jogador a fazer frequentes ajustes que, se não realizados, levarão ao desprendimento total do dispositivo da raquete, uma vez que não existe um mecanismo para sua fixação às cordas. [005] The above solution, while well attached to the strings of the racket, performs well its anti-vibration function, however, during the game, with the impacts of the ball, it tends to loosen up causing the player to make frequent adjustments that, if not performed, will lead to the total detachment of the racket device, since there is no mechanism for its attachment to the strings.
[006] O WO 85/05556 intitulado“ Vibration Dampening Device for Sporting Rackets " - se refere a um dispositivo de amortecimento de vibração de formato cilíndrico, fabricado em espuma. O dispositivo possui entalhes perimetrais justapostos apropriados para, quando devidamente encaixados, abarcarem quatro cordas da raquete. [006] WO 85/05556 entitled “Vibration Dampening Device for Sporting Rackets" - refers to a cylindrical shaped vibration damping device, made of foam. The device has juxtaposed perimeter grooves appropriate to, when properly fitted, cover four strings of the racket.
[007] O dispositivo supracitado apresenta como principais inconvenientes, o difícil manuseio e/ou posicionamento nas cordas da raquete, tornando quase impossível o seu ajuste durante a partida e, tal qual a primeira anterioridade, não possui um mecanismo de fixação à raquete. [007] 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.
[008] O WO 2017/009699 intitulado“Vi bration Dampening Devicesand System " - se refere a um dispositivo de amortecimento a ser utilizado em cordas de raquetes de tênis, o qual possui um elemento de fixação representado por uma aba com encaixe macho e outra aba com encaixe fêmea, formatando um grampo“C” capaz de abarcar até duas cordas da raquete. [008] 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.
[009] O dispositivo supracitado, apesar de possuir elemento de fixação tipo macho e fêmea, ainda apresenta alguns limitantes técnicos devido ao seu formato de grampo “C” e ao elemento de fixação único. O formato em grampo tende a exercer uma força no sentido de abrir o dispositivo, devido a massa de material concentrada na curvatura do grampo. Outrossim, neste formato de grampo o vão para inserção das cordas é livre, o que faz com que o movimento das cordas dentro do mesmo não seja limitado, o que potencializa os impactos e seus efeitos contra o sistema de fechamento, podendo colapsá-lo. [009] 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. Furthermore, in this clamp format, 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.
Objetivos da inovação Innovation objectives
[010] É objetivo da presente inovação, propor um dispositivo antivibracional que delimita e distribui, em dois lados distintos, o impacto e consequente vibração causada pela bola nas cordas da raquete, além de evitar o seu desacoplamento inesperado durante a partida de tênis. [010] 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.
[011 ] É objetivo da presente inovação, propor um dispositivo antivibracional capaz de amortecer o máximo possível o impacto da bola nas cordas da raquete de tênis durante a partida. [011] 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.
