Description

racket

This creation is about a shooting device.

In modern life, in order to maintain posture and health, various sports have become an indispensable part of people's daily life. When performing various sports, it is usually necessary to use or equip corresponding sports equipment.

For example, a variety of ball games such as tennis rackets, squash rackets, badminton rackets, jai racquets, cricket, and the like are performed with rackets. A general racket includes a hitting head and a handle. The hitting head includes a frame and a hitting member (such as a plate, a net, or the like) disposed in the frame. Wherein, if the ball striking member has a considerable thickness and a solid structure, the manufacturing raw materials (plastic, wood, metal, etc.) require a large amount of materials and increase the cost, which will also cause the racket to have a large weight, which is unfavorable for hitting.

Therefore, it is necessary to provide a novel and progressive beater to solve the above problems.

The main purpose of the present creation is to provide a racket with sufficient structural strength and low weight, which is light and can be operated lightly and agilely.

In order to achieve the above-mentioned purpose, this creation provides a racket, including: a frame body, including a frame wall and a handle connected to each other, the frame wall encloses a accommodating space; a three-dimensional grid is arranged in the accommodating space In the space and fixed to the frame wall on one side, it includes a plurality of passages penetrating between the two sides in the thickness direction of the three-dimensional grid; To the frame wall, each of the beater surfaces includes a plurality of through holes, and the plurality of through holes correspond to and communicate with the plurality of passages.

The following examples only illustrate the possible implementation of this creation, but are not intended to limit the scope of protection of this creation, and will be described first.

Please refer to FIGS. 1 to 5 , which show a preferred embodiment of the present creation. The paddle 1 of the present creation includes a frame body 10 , a three-dimensional grid 20 and a second-beat face 30 .

The frame body 10 includes a frame wall 11 and a handle 12 which are connected to each other. The frame wall 11 encloses an accommodating space 13 ; the three-dimensional grid 20 is disposed in the accommodating space 13 and is fixed to the The frame wall 11 and the three-dimensional grid 20 include a plurality of channels 21 (which can be linear through holes, or non-linear between the brackets of the three-dimensional grid 20 ) penetrating between the two sides of the three-dimensional grid 20 in the thickness direction. space); the two beater surfaces 30 are arranged on two opposite sides of the three-dimensional grid 20 and are fixed to the frame wall 11, each of the beater surfaces 30 includes a plurality of through holes 31, and the plurality of through holes 31 correspond to and communicate with the frame wall 11. Multiple channels 21. Therefore, the three-dimensional grid 20 has sufficient structural strength and low weight, so that the racket is lightweight and can be operated lightly and agilely.

Preferably, an inner surface of the frame wall 11 is radially concave, and an outer peripheral surface of the three-dimensional grid 20 is radially outwardly convex, whereby the three-dimensional grid 20 can be stably installed on the frame wall 11 without being easily dislodged. out. However, the inner side of the frame wall 11 and the outer peripheral surface of the three-dimensional grid 20 may be flat. The outer peripheral surface of the three-dimensional grid 20 is preferably annular, continuous and closed, so as to increase the connection area and connection strength with the inner side of the frame wall 11 .

In this embodiment, the frame body 10 is a reinforced fiber component, the three-dimensional grid 20 further includes two opposite side layers 22 and a frame 23 integrally connected between the two side layers 22, and the two-beat face 30 is reinforced The fiber components are respectively covered on the two side layers 22. The reinforced fiber (such as glass fiber, carbon fiber or the like) component has the characteristics of light weight and good structural strength. It is relatively flat, and the two side layers 22 are, for example, pre-impregnated fiber cloth laid on the two-beater surface 30 and then hardened and formed. Each of the side layers 22 is provided with a plurality of openings 221 , and the frame 23 includes a plurality of communication holes 231 . The plurality of communication holes 231 correspond to and communicate with the openings 221 of the side layers 22 . Reduces air resistance when hitting. In other possible embodiments, the three-dimensional grid 20 and the two-shot surface 30 can be integrally formed into a single component of the same material, which is convenient and quick to manufacture.

Preferably, the three-dimensional grid 20 is a light-hardening resin (UV light-hardening resin) member, which has a certain degree of support strength and elastic deformation ability after being formed. The resin is directly molded after hardening, and the process is simple and fast. For example, the photo-curable resin is contained in a container whose bottom side can transmit light, and a forming platform is sunk into the container and is close to the bottom side of the container. Projecting light onto the forming platform to harden and form part of the grids corresponding to the cross-sectional patterns, the forming platform is sequentially away from the bottom side of the container, and finally the three-dimensional grid 20 is grown. The overall process is simple and fast. Lower manufacturing cost. However, the three-dimensional grid 20 can also be formed by using other various forms of 3D printing technology.

Preferably, the three-dimensional grid 20 further includes a first portion 24 that is closer to the handle 12 and a second portion 25 that is farther away from the handle 12. The grid density per unit volume of the second portion 25 is greater than that of the second portion 25. The grid density per unit volume of the first part 24. Thereby, the peripheral portion near the sweet center point of the beater 1 has better structural strength and swipe inertia, which improves the swipe effect and also increases the durability.

In other possible embodiments, the frame wall 11 further includes a partition part 111 , the partition part 111 is radially extended from an inner surface of the frame wall 11 , and the partition part 111 is preferably a reinforced fiber member. The three-dimensional grid 20 a is disposed on two opposite sides of the partition portion 111 , and is connected to the frame wall 11 and the partition portion 111 through the adhesive material 40 . The partition portion 111 can extend continuously to radially traverse the housing space of the frame. The partition portion 111 includes a plurality of through holes 112 corresponding to and communicated with the plurality of channels 21. The three-dimensional The mesh frame 20 a includes a first mesh frame 26 and a second mesh frame 27 disposed on opposite sides of the partition portion 111 . The first mesh frame 26 and the second mesh frame 27 are connected to the mesh frame through an adhesive material 40 . The frame wall 11 and the partition portion 111 (the second preferred embodiment shown in FIG. 6 and FIG. 7 ); alternatively, the partition portion 111a can be a ring flange and annularly connected to the inner side of the frame wall 11 , the three-dimensional grid 20 includes a first grid 26 and a second grid 27 disposed on two opposite sides of the partition portion 111a, the first grid 26 and the second grid 27 pass through the adhesive material 40 Connected to the frame wall 11 and the partition portion 111a, and connected to each other through the adhesive material 40 (the second preferred embodiment shown in FIG. 8 and FIG. 9 ), preferably, the first grid 26 and The second grid 27 is respectively provided with a ring 261, 271 at the peripheral portion, and the partition portion 111a is embedded in the ring 261, 271 of the first grid 26 and the second grid 27, so that the combination is more Flat and stable. The partition part can increase the structural strength and the slapping effect, and the first grid frame and the second grid frame are respectively arranged to make the assembly and manufacture more convenient and fast.
