Description

[Technical Field]

[0001] This utility model relates to the field of ball sports equipment technology, and more particularly to the field of rough board composite fabric technology for beach rackets, peak rackets or snow rackets. [Background Technology]

[0002] With the rise of peakball, more and more people and sports enthusiasts are getting involved in the sport. Peak racket manufacturing processes have also been continuously upgraded and improved to meet consumer needs and provide a better user experience.

[0003] Whether it's a Peak racket, a beach racket, or a snow racket, all rackets need to meet certain requirements for hitting elasticity and impact resistance. Furthermore, while maintaining wear and impact resistance, they also need to be lightweight. As skill levels advance, higher demands are placed on the racket's striking ability, requiring it to produce higher-quality shots. This places high demands on the racket's manufacturing process and the materials used. For example, patent CN202322998140.X discloses a shock-absorbing and wear-resistant Peak racket, which features cushioning surfaces installed on both the front and rear ends of the racket blade. This allows the ball to collide with the cushioning surfaces, offsetting some of the impact force and reducing the impact force on the blade, thus achieving a shock-absorbing effect.

[0004] However, according to publicly available documents, the Peak racket incorporates a cushioning spring in its buffer surface. This structure is not only complex but also significantly increases the racket's weight, hindering efforts to reduce its overall weight. Furthermore, it is not conducive to prolonged use and can lead to fatigue. Additionally, this racket design prioritizes cushioning over improved serve performance, neglecting the strength of the racket's core material and the overall hitting effect, resulting in a less durable racket or mediocre performance. [Summary of the Invention]

[0005] This invention addresses the above problems by proposing a racket with a rough panel. It utilizes a rough surface formed by hot pressing a release cloth, and combines a shielding material to form an intermittent rough surface and a smooth surface, thereby creating a significant difference in the racket surface. This results in a better spin propulsion effect on the ball during a hit, leading to a better spin hitting effect.

[0006] A rough panel, characterized in that the panel comprises:

[0007] Support material layer;

[0008] A roughening layer is provided on the supporting material layer;

[0009] A shielding material is laid on the supporting material layer, and the shielding material is sandwiched between the supporting material layer and the roughening layer.

[0010] The supporting material layer is a carbon fiber / glass fiber prepreg fabric. The carbon fiber prepreg fabric is a fabric made by hot pressing carbon fiber material prepreg with epoxy resin, while the glass fiber prepreg fabric is a fabric made by hot pressing glass fiber prepreg with epoxy resin.

[0011] The rough layer of the rough panel is formed by impregnating release cloth with epoxy resin, molding it, and then peeling off the release cloth and the masking material.

[0012] The release fabric includes a coarse release fabric with a thickness of 0.4 mm and a fine release fabric with a thickness of 0.02 mm. The release fabric used for molding onto the rough layer is a coarse release fabric and / or a fine release fabric.

[0013] When the release fabric is a coarse release fabric and a fine release fabric, the two are separated by a shielding material. After molding, the coarse release fabric, the fine release fabric and the shielding material are peeled off at the same time, forming a rough layer that has both coarse and fine release fabric textures.

[0014] The covering material is a sticker with sticky, regular stripes, repeating patterns, or designs.

[0015] A racket made with a roughened panel includes a handle and a racket part, the racket part being fixedly connected to the handle, the handle including a handle, the racket part including a frame, a core material plate, and a cover plate made of the roughened panel, the handle being integrally formed with the frame to form a main frame, the main frame having a mounting position, the core material plate being detachably disposed in the mounting position, and the cover plate being detachably disposed on the main frame.

[0016] Two cover plates are provided. Each cover plate includes a front panel and a handle edge strip. The front panel and the handle edge strip are integrally formed. The two cover plates are installed on the main frame from both sides of the racket part. The handle edge strip covers the handle and is covered with handle grip material on both sides.

[0017] The racket with a rough panel involved in this utility model utilizes a rough surface formed by hot pressing a release cloth, and an intermittent rough surface and a smooth surface formed by combining a shielding material on the rough surface, so that the racket surface has a significant drop, which can generate a better spin propulsion effect on the ball when hitting it, and obtain a better spin hitting effect.

Therefore, they should not be construed as limitations on this utility model.

[0030] Please refer to the attached document. Figure 1 and attached Figure 2 The diagram shows the roughened panel 10 according to the present invention, and a racket made using the roughened panel, characterized in that the roughened panel 10 comprises:

[0031] Support material layer 11;

[0032] A rough layer 12 is provided on the support material layer 11;

[0033] A shielding material 14 is laid on the support material layer 11, and the shielding material 14 is sandwiched between the support material layer 11 and the rough layer 12.

[0034] The supporting material layer 11 is a carbon fiber / glass fiber prepreg fabric. The carbon fiber prepreg fabric is a fabric made by hot pressing carbon fiber material prepreg with epoxy resin, while the glass fiber prepreg fabric is a fabric made by hot pressing glass fiber prepreg with epoxy resin.

[0035] The rough layer 12 of the rough panel 10 is formed by impregnating the release cloth 15 with epoxy resin, molding it, and then peeling off the release cloth 15 and the shielding material 14.

[0036] Please refer to the attached document. Figure 2 The rough panel is die-cut into a shape suitable for the racket, and shaped into the racket panel material, thus obtaining a racket made of rough panel.

[0037] The release cloth 15 includes a coarse release cloth with a thickness of 0.4 mm and a fine release cloth with a thickness of 0.02 mm. The release cloth used for molding onto the rough layer is a coarse release cloth and / or a fine release cloth.

[0038] That is, a rough panel can use only one type of coarse release cloth or only one type of fine release cloth. That is, after conventional impregnation with epoxy resin and molding, the release cloth and the masking material are peeled off to create a rough layer with a single coarse and fine texture.

[0039] Another method involves using both coarse and fine release fabrics when creating a rough panel. These are separated by a barrier material. After molding, the coarse and fine release fabrics, along with the barrier material, are simultaneously peeled off, resulting in a rough layer with both coarse and fine release fabric textures. This allows for the simultaneous creation of two different textures on a single rough panel.

[0040] Please refer to the attached document. Figure 3 ~Appendix Figure 5 The text describes three different types of rough-surfaced rackets, including those with both coarse and fine textures. Figure 3 The area is divided into several unit areas, some of which are covered by coarse lines and others by fine lines; Figure 4 The medium-roughness panel is divided into two areas by the material used to cover it: one area has a coarse texture, and the other area has a fine texture. Figure 5 The image shows a structure where fine lines surround coarse lines. The methods described above are merely examples and not limitations.

[0041] Due to the presence of the shielding material 14, the rough texture on the formed rough layer 12 is not imprinted onto the release cloth, resulting in a smooth surface. The part that directly contacts the release cloth 15 retains the rough texture, thus forming the final rough layer 12.

[0042] The rough layer 12 has a portion printed onto the release cloth and a portion of the release cloth 15 without printing, creating a clear difference in height. This can be used as a striking surface, making it easier to increase the spin and backspin of the ball when hitting it, making it harder for the opponent to receive the ball.

[0043] Please refer to the attached document. Figures 6-7 The image shows the masking material 14, which is a sticker with adhesive, regular stripes, repeating patterns, or designs. It can be a square grid, a diamond grid, or a single diamond pattern. Figures 6 to 7 The racket uses different shaped shielding materials 14 to form different shaped rough panels. The above shapes are just examples and are not limitations. Other shapes that meet the requirements can also be used.

[0044] Please refer to the attached document. Figure 8The diagram illustrates the overall structure of the racket 100 made of the roughened panel, including a handle portion 120 and a racket portion 110. The racket portion 110 is fixedly connected to the handle portion 120. The handle portion 120 includes a handle 121. The racket portion 110 includes a frame 111, a core material plate 112, and a cover plate 113 made of the roughened panel. The handle 121 and the frame 111 are integrally formed into a main frame. The main frame is provided with a mounting position 114. The core material plate 112 is detachably disposed in the mounting position 114. The cover plate 113 is detachably disposed on the main frame.

[0045] Two cover plates 113 are provided. Each cover plate 113 includes a panel 1131 and a handle edge strip 1132. The panel 1131 and the handle edge strip 1132 are integrally formed. The two cover plates 1131 are installed on the main frame from both sides of the racket part. The handle edge strip 1132 covers the handle 121 and is covered with handle grip material 122 on both sides.

[0046] The racket with a rough panel involved in this utility model utilizes a rough surface formed by hot pressing a release cloth, and an intermittent rough surface and a smooth surface formed by combining a shielding material on the rough surface, so that the racket surface has a significant drop, which can generate a better spin propulsion effect on the ball when hitting it, and obtain a better spin hitting effect.
