Description

Technical Field

[0001] This utility model relates to rackets, and more particularly to a racket patch and a racket using the same. Background Technology

[0002] Existing rackets (such as Peak rackets) typically have a hitting surface and a handle. The hitting surface is often made of a smooth material or has only a basic coefficient of friction. Some rackets have multiple perforations in the hitting surface to reduce wind resistance, lighten weight, and absorb shock. When the user hits the ball, insufficient friction or reduced contact area can easily lead to decreased ball control and poor spin, thus affecting performance.

[0003] To address these issues, existing technologies have proposed molding a friction-enhancing layer integrally onto the racket face, such as applying an anti-slip coating or embossing directly to increase friction. However, this friction-enhancing layer is integrally molded onto the racket face, making it impossible to adjust its position or area locally according to user needs. Furthermore, when this friction-enhancing layer wears out or is damaged, it often requires replacing the entire racket or re-processing the racket face, resulting in high maintenance costs and inconvenience for practical application.

[0004] Therefore, it is necessary to provide a novel and progressive racket patch and a racket using it to solve the above problems. Utility Model Content

[0024] The following examples illustrate possible implementations of this utility model, but are not intended to limit the scope of protection of this utility model. The prefixes "a" or "at least one" before the terms mentioned herein are not intended to limit the quantity. Depending on the requirements, there may also be "multiple" items. This variation in quantity is also within the scope of protection, as will be stated in advance.

[0025] Please refer to Figures 1 to 5 This shows a preferred embodiment of the present invention, wherein the racket patch 1 of the present invention includes a release paper 10 and a patch body 20.

[0026] The patch body 20 has a first through hole 21 and includes a substrate layer 22, a particle layer 23 and a first adhesive layer 24. The particle layer 23 and the first adhesive layer 24 are stacked on opposite sides of the substrate layer 22. The first adhesive layer 24 is detachably attached to the release liner 10.

[0027] The granular layer 23 comprises a plurality of abrasive particles of varying sizes, with an average particle size between 0.01 mm and 0.80 mm. These abrasive particles form a rough surface on the granular layer 23, thereby increasing surface friction. For example, the abrasive particles are #220 white alumina steel grit, containing more than 99.4% alumina and with an average particle size between 53 micrometers and 63 micrometers (62 micrometers in this embodiment), exhibiting good hardness and wear resistance. Furthermore, the granular layer 23 also includes a matrix for connecting the abrasive particles. The weight ratio of the abrasive particles to the matrix is ​​between 0.3 and 0.8 (preferably between 0.45 and 0.65) to provide sufficient surface roughness. In this embodiment, the matrix is ​​a printing coating, and the granular layer 23 can be applied to the substrate layer 22 using printing technology, facilitating processing and ensuring high precision.

[0028] Furthermore, the thickness of the substrate layer 22 is not less than the thickness of the particle layer 23 and is between 0.3 mm and 0.8 mm (0.5 mm in this embodiment). The substrate layer 22 can be made of materials such as polyethylene terephthalate (PET), polycarbonate (PC), polyvinyl chloride (PVC), and polyethylene (PE), thereby maintaining the continuity and integrity of the patch body 20 and facilitating the adhesion operation. Preferably, the substrate layer 22 is a transparent film, the plurality of frosted particles are semi-transparent particles, and the particle layer 23 further includes a plurality of color particles (e.g., blue pearl powder). Thus, when the patch body 20 is attached to a racket face 211 of a racket 2, the patch body 20 will not completely obscure the pattern and color on the racket face 211, and the plurality of color particles can provide different visual effects, increasing the appearance variation of the racket face 211, thus balancing aesthetics and functionality. In other embodiments, the substrate layer 22 may also be designed to be other colors or to be opaque, and the plurality of frosted particles may also be made of materials with other colors or translucency to meet different appearance requirements.

[0029] In this embodiment, the patch body 20 is annular, with a diameter between 20 mm and 25 mm. The diameter of the first perforation 21 is between 10 mm and 15 mm, and can be designed according to the size of the through hole 212 on the racket 2. The first adhesive layer 24 is acrylic adhesive, with a thickness between 0.05 mm and 0.15 mm. It has good transparency and can be widely used on different bonding surfaces to achieve stable adhesion and prevent it from falling off.

[0030] Preferably, the racket patch 1 further includes a protective film 30, which comprises a transparent film layer 31 and a second adhesive layer 32 stacked on top of each other. The protective film 30 is detachably attached to the particle layer 23 and the release liner 10 through the second adhesive layer 32. The protective film 30 completely covers the rough surface and protrudes radially from the outer periphery of the rough surface, thereby preventing the particle layer 23 from being worn by external forces, maintaining its structural and appearance integrity, and facilitating the adhesion of the patch body 20.

[0031] Furthermore, the release liner 10 includes two halves 11, which are separated from each other by a break line 12 for easy adhesion. The release liner 10 also includes a second perforation 13, which is concentrically opposite to the first perforation 21 and preferably has the same radial dimension, aiding in alignment during adhesion. In the sale process, a plurality of racket patches 1 can be interconnected, with a partial break line 14 between each release liner 10 for partial separation, such as... Figure 5 As shown, this helps improve mass production and packaging efficiency, and reduces the difficulty of operation for users.

[0032] Reference Figures 6 to 8 In use, first peel off one half 11 from the first adhesive layer 24, and align the first perforation 21 or the second perforation 13 with the through hole 212 on the racket surface 211, so that the first adhesive layer 24 is partially attached to the racket surface 211. Figure 6 At this point, since the first adhesive layer 24 is not completely attached to the pad surface 211, and the protective film 30 can maintain the integrity of the patch body 20, the adhesive position can still be moved and adjusted. Then, the other half 11 is peeled off from the first adhesive layer 24, so that the first adhesive layer 24 is completely attached to the pad surface 211. Figure 7 The adhesive position of the patch body 20 is determined. Finally, the protective film 30 covers the first perforation 21 and has a cut 33 corresponding to the first perforation 21. The user can peel the protective film 30 off the pad surface 211 and the patch body 20 through the cut 33 or the corner of the protective film 30. Figure 8 This completes the placement of the patch body 20. The aforementioned operation method provides step-by-step positioning and protection, improves placement accuracy, and avoids misplacement.

[0033] This utility model also provides a racket 2, which uses at least one racket patch 1 as described above, and further includes: a hitting part 210 and a handle part 220 connected to the hitting part 210. The hitting part 210 includes two racket faces 211 facing each other along a thickness direction and a plurality of through holes 212 penetrating the two racket faces 211. Each patch body 20 surrounds one of the through holes 212 and is attached to one of the racket faces 211 with the first adhesive layer 24, such as... Figure 9As shown. The racket 2 is, for example but not limited to, a Peak racket. The user can apply at least one racket patch 1 to the two racket faces 211 according to personal needs, such as to the sweet spot of the two racket faces 211, to increase friction resistance. This allows the racket 2 to provide excellent hitting control and spin while reducing shock, wind resistance and weight.

[0034] The above description is a preferred embodiment of the present utility model and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solution of the present utility model without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
