Exposición de una realización preferenteExhibition of a preferred embodiment

Tal y como se muestra en la Fig. 1, una raqueta de pádel 10 de acuerdo con una primera realización de la presente invención comprende un armazón 20 y una mango 30.As shown in Fig. 1, a racket of paddle 10 according to a first embodiment of the present The invention comprises a frame 20 and a handle 30.

El armazón 20 tiene una forma plana con dos superficies paralelas que golpean la pelota 22 para golpear una pelota. Se forman cuatro concavidades 24 y tres convexidades 26 en cada uno de los lados laterales opuestos de la periferia del armazón 20 y están dispuestos de manera alternativa. Es decir, cada convexidad 26 está situada entre dos concavidades 24. Cada convexidad 26 tiene un costado superior 261 que mira radialmente hacia el exterior del armazón, cuatro lados laterales que rodean el lado superior 261 y un canal orientador de aire 265 que se extiende a través. Cada canal orientador de aire 265 se extiende en una dirección perpendicular a las superficies que golpean la pelota 22 y está provisto de dos aberturas 267 en lados laterales opuestos 263 de la convexidad 26.The frame 20 has a flat shape with two parallel surfaces that hit the ball 22 to hit a ball. Four concavities 24 and three convexities 26 are formed in each of the opposite side sides of the periphery of the frame 20 and are arranged alternately. That is, each convexity 26 is located between two concavities 24. Each convexity 26 has an upper side 261 that looks radially towards the outside of the frame, four lateral sides surrounding the upper side 261 and an air guide channel 265 extending through. Each air guide channel 265 extends in a direction perpendicular to the surfaces hitting the ball 22 and it is provided with two openings 267 on opposite sides 263 of convexity 26.

El mango 30 tiene un extremo conectado al armazón 20.The handle 30 has one end connected to the frame 20.

Debido a que hay un número de concavidades 24 y canales orientadores de aire 265 formados en la periferia del armazón 20, el peso de la raqueta de pádel 10 puede reducirse hasta cierto punto que aumente la flexibilidad de la raqueta durante su uso. Por lo tanto, la raqueta de pádel 10 puede manipularse y balancearse con muy poco esfuerzo por parte del usuario. Así mismo, cuando el usuario balancea la raqueta de pádel 10, el aire pasará al armazón 20 a través de las concavidades 24 y a través de los canales orientadores de aire 265, de modo que la resistencia experimentada por la raqueta de pádel 10 que se mueve a través del aire se reducirá, aumentado de este modo la flexibilidad de uso de la raqueta de pádel 10. Además, debido a que las concavidades 24 y los canales orientadores de aire 265 están formados en la periferia del armazón 20 que normalmente no golpea la pelota, la disposición de las concavidades 24 y los canales orientadores de aire 265 no influenciarán en la habilidad para golpear la pelota ni la fuerza con la cual se puede golpear.Because there are a number of concavities 24 and 265 air guide channels formed on the periphery of the frame 20, the weight of the paddle racket 10 can be reduced to certain point that increases the flexibility of the racket during use. Therefore, the paddle racket 10 can be manipulated and swing with very little effort from the user. Likewise, when the user balances the paddle racket 10, the air will pass to the frame 20 through the concavities 24 and through the channels 265 air orientators, so that the resistance experienced by the paddle racket 10 that moves through the air is will reduce, thereby increasing the flexibility of use of the paddle racket 10. Also, because the concavities 24 and the air orientating channels 265 are formed on the periphery of the frame 20 that normally does not hit the ball, the arrangement of concavities 24 and air guidance channels 265 no influence the ability to hit the ball or force with which you can hit.

Se debe entender que la forma de los canales orientadores de aire no se limita al tipo mostrado en la Fig. 1. Tal y como se muestra en la Figura 2, una raqueta de pádel 40 de acuerdo con una segunda realización de la presente invención también comprende un armazón 50 y un mango 60 conectado al armazón 50. El armazón también tiene un conjunto de concavidades 54 y convexidades 56 tal y como se muestra en la Fig. 1. Sin embargo, en esta realización el canal orientador de aire 565 de cada convexidad 56 tiene una forma en cruz y todo el canal orientador de aire 565 de la respectiva convexidad 56 está localizado en un plano imaginario 58. El canal orientador de aire 565 de cada convexidad 56 está provisto de cuatro aberturas 567, que respectivamente están formadas en cuatro lados laterales 563 de la convexidad 56.It should be understood that the shape of the channels Air orientators are not limited to the type shown in Fig. 1. Such and as shown in Figure 2, a paddle racket 40 according with a second embodiment of the present invention also it comprises a frame 50 and a handle 60 connected to the frame 50. The frame also has a set of concavities 54 and convexities 56 as shown in Fig. 1. However, in this realization of the air guide channel 565 of each convexity 56 it has a cross shape and the entire air guide channel 565 of the respective convexity 56 is located in an imaginary plane 58. The air guide channel 565 of each convexity 56 is provided of four openings 567, which are respectively formed in four lateral sides 563 of convexity 56.

Tal y como se muestra en las Fig. 3 y Fig. 4, una raqueta de pádel 70 de acuerdo con una tercera realización de la presente invención también comprende un armazón 80 y un mango 90 conectado al armazón 80 tal y como se ilustra en las Figs. 1 y 2. El armazón 80 también tiene un conjunto de concavidades 84 y convexidades 86. Sin embargo, el canal orientador de aire 865 de cada convexidad 86 tiene una forma de T y todo el canal orientador de aire 865 con forma de T de la respectiva convexidad 86 está situado en un plano imaginario 88 en paralelo a las superficies que golpean y en ángulos derechos al plano 58 de la Fig. 2. El canal orientador de aire 865 de cada convexidad 56 está provisto de tres aberturas 867a y 867b. Una abertura 867a está formada en el lado superior 861 de la convexidad 86 y las otras dos aberturas 867b están respectivamente formadas en los lados opuestos laterales 863 de la convexidad 86.As shown in Fig. 3 and Fig. 4, a paddle racket 70 according to a third embodiment of the The present invention also comprises a frame 80 and a handle 90 connected to the frame 80 as illustrated in Figs. 1 and 2. The frame 80 also has a set of concavities 84 and convexities 86. However, the air guide channel 865 of each convexity 86 has a T-shape and the entire orientation channel T-shaped air 865 of the respective convexity 86 is located in an imaginary plane 88 parallel to the surfaces that they hit and at right angles to plane 58 of Fig. 2. The channel air orientator 865 of each convexity 56 is provided with three openings 867a and 867b. An opening 867a is formed on the side upper 861 of convexity 86 and the other two openings 867b they are respectively formed on opposite sides 863 of convexity 86.

La raqueta de pádel puede tener diferentes diseños dentro del alcance de la presente invención. Por ejemplo, el número y la posición de las convexidades, las concavidades y las aberturas no se limitan a las realizaciones mencionadas. Si se desean, se pueden cambiar. Además, la forma de cada canal orientador de aire no se limita a la forma lineal, forma de cruz o forma de T. También pueden adoptar formas radiales, formas curvadas, formas irregulares, etc.The paddle racket can have different designs within the scope of the present invention. For example, him number and position of convexities, concavities and openings are not limited to the aforementioned embodiments. Whether They want, they can be changed. In addition, the shape of each orientation channel of air is not limited to the linear form, cross shape or T shape. They can also adopt radial shapes, curved shapes, shapes irregular, etc.
