Description

Technical Field

[0001] This utility model relates to a racket, and more particularly to a Peak racket structure that can reduce audio and increase elasticity. Background Technology

[0002] Peakball is a sport that combines elements of tennis, badminton, and table tennis. The ball is about the size of a tennis ball, but is a thin-shelled, hollow ball made of hard plastic with multiple openings on its surface. Peak rackets are shaped like larger table tennis rackets, including the racket body and handle. Traditionally, they were made of wood and were quite heavy. Currently, rackets made of lighter polypropylene (PP) honeycomb sheets covered with carbon fiber cloth have been developed. This not only maintains the structural strength of the racket but also effectively reduces its overall weight, making swings more effortless and easier.

[0003] However, while conventional Peak rackets made of polypropylene honeycomb panels have the advantage of being lightweight, they transmit greater vibrations to the racket handle upon impact, resulting in poorer elasticity and a loud, high-frequency sound. Therefore, in certain environments, such as residential communities, playing Peak rackets can easily generate noise and cause disturbance. Furthermore, because the polypropylene honeycomb panel and carbon fiber cloth are different materials, their bonding is not good, making them prone to delamination. In view of these reasons, the inventors of this invention believe that conventional Peak rackets require further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a Peak racket structure that can reduce audio and increase elasticity. In addition to making the racket body and handle integrated to achieve better strength and lightness, it can also effectively reduce the audio and volume when hitting the ball and increase the elasticity of the shot.

[0005] To achieve the above objectives, the present invention provides a Peak racket structure that can reduce audio and increase elasticity, comprising a core, which is integrally formed from fiber material into a racket body and a handle, with a racket face formed on the upper and lower sides of the racket body; a plurality of hollow portions are arranged parallel to each other in the core along the direction of the racket face; and a plurality of foam materials are respectively arranged between the hollow portions along the direction of the racket face.

[0006] Furthermore, the core has a surface layer on its upper and lower sides, and these surface layers are also made of fiber material.

[0007] Furthermore, the radial cross-sections of these hollow sections are rectangular.

[0008] Furthermore, the core body covers the periphery of these hollow sections. Attached Figure Description

[0042] Please see Figures 1 to 2 As shown, a Peak racket structure that reduces audio and increases elasticity is disclosed. The Peak racket includes:

[0043] A core 10 is made of fiber material. In a preferred embodiment of the present invention, carbon fiber is selected as the main material, but the material is not limited to this. The core 10 is integrally formed into a racket body 11 and a handle 12 of a Peak racket. A racket face 111 is formed on the upper and lower sides of the racket body 11. A surface layer 13 is provided on the upper and lower sides of the core 10. The surface layer 13 is also made of carbon fiber material. The surface layer 13 can effectively strengthen the structural strength of the core 10, so that the core 10 can withstand a certain degree of impact and avoid damage due to impact.

[0044] Multiple hollow portions 20 are arranged parallel to each other in the core 10 along the direction of the striking surfaces 111, so that a gap 14 is formed between each of the hollow portions 20 in the core 10. In a preferred embodiment of the present invention, the radial cross-section of the hollow portions 20 is rectangular, and the periphery of the hollow portions 20 is covered by the core 10.

[0045] Multiple foam materials 30 are respectively disposed in the gaps 14 and completely fill the gaps 14. In a preferred embodiment of the present invention, the radial cross-section of the foam materials 30 is rectangular, and the foam materials 30 are made of polyurethane (PU), but are not limited to this material.

[0046] To further understand the structural features, technical means, and expected effects of this utility model, the manufacturing method of this utility model will be described in more detail below. It is believed that this will provide a deeper and more specific understanding of this utility model, as follows:

[0047] Please see Figures 3 to 7As shown, the manufacturing method of this Peak racket includes the following steps: (a) Material preparation: Prepare a mold 200. In this embodiment, the mold 200 consists of a rectangular upper mold 210 and a corresponding lower mold 220. The upper mold 210 has multiple upper grooves 211 on its two corresponding end faces, and the lower mold 220 has multiple lower grooves 221 on its two corresponding end faces. In addition, prepare two first fiber cloths 40, multiple tubes 50 and multiple foam strips 60. A second fiber cloth 70 is wrapped around the outer periphery of the middle section of each tube 50. The first fiber cloths 40 and the second fiber cloths 70 are all made of fiber material. In the preferred embodiment of this utility model, carbon fiber is selected as the main material, but it is not limited to this material. The first fiber cloths 40 and the second fiber cloths 70 can be fused together after heating.

[0048] (b) Inserting into the mold: The first fiber cloths 40 are respectively laid on the upper and lower bottom surfaces of the mold 200. The tubes 50 are arranged in parallel and spaced apart in the mold 200, with the two ends of the tubes 50 respectively placed between the upper grooves 211 and the lower grooves 221. The two ends of the tubes 50 extend from the upper grooves 211 and the lower grooves 221 to the outside of the mold 200. The gaps 14 are formed between adjacent tubes 50. The foam strips 60 are respectively placed in the gaps 14, so that the tubes 50 and the foam strips 60 are located between the first fiber cloths 40. The foam strips 60 are made of polyurethane (PU), but are not limited to this material.

[0049] (c) Heating and pressurizing: After the upper mold 210 and lower mold 220 of the mold 200 are closed, the mold 200 is heated so that the heating temperature exceeds the melting point temperature of the first fiber cloth 40 and the second fiber cloth 70, so that the first fiber cloth 40 and the second fiber cloth 70 fuse together. At this time, the foam strips 60 expand due to the heat and completely fill the gaps, thereby forming the foam material 30.

[0050] (d) Cooling and curing: Stop heating the mold 200 and wait for it to cool down. The first fiber cloth 40, the second fiber cloth 70 and the foam strips 60 are all in a cured state to form the core 10, and the surface layers 13 are formed on the upper and lower surfaces of the core 10.

[0051] (e) Remove the tubes: The tubes 50 are pulled out of the mold 200, so that the core 10 forms a plurality of hollow portions 20 at the original positions of the tubes 50.

[0052] (f) Obtaining the semi-finished product: Remove the semi-finished product from the mold 200.

[0053] (g) Cutting and shaping: The semi-finished product is cut to form the prototype of the racket body 11 and the handle 12. (h) Finished product: Finally, the racket body 11 and the handle 12 are covered to obtain the finished Peak racket.

[0054] The features of this utility model and its expected effects are described below:

[0055] 1. The racket body and handle of this utility model are integrally molded from fiber materials such as carbon fiber, thus producing better strength.

[0056] 2. This utility model has multiple foam materials embedded in the core. Since the foam materials have elasticity and vibration damping effects, they can increase the elasticity of the hit when the Peak racket hits the ball and reduce the vibration transmitted to the racket handle when hitting the ball, thereby improving the comfort of hitting the ball.

[0057] 3. This utility model has multiple hollow parts embedded in the core. The direction of these hollow parts is parallel to the racket face, which makes the tube of these hollow parts longer, thereby achieving the effect of suppressing sound. Therefore, it can not only reduce the weight of the racket body, but also effectively reduce the audio and volume of the ball when hitting it.

[0058] 4. This utility model is made of fiber material as a single material and is manufactured in one piece by mold. Therefore, it does not have the disadvantage of traditional honeycomb board core, which is prone to delamination.

[0059] However, the above description is only a preferred embodiment of the present utility model. Therefore, any equivalent structural changes made in accordance with the present utility model specification and claims should be included within the patent scope of the present utility model.
