Description

Technical Field

[0001] This invention relates to the field of sports equipment, and in particular to a Peak racket with anti-detachment layer and its manufacturing method. Background Technology

[0002] See Figure 1 The image shows a cross-sectional view of a Peak racket 10, which includes two carbon fiber plates 101, two polyester layers 102 disposed between the carbon fiber plates 101, and a honeycomb plate 103 disposed between the polyester layers 102. The carbon fiber plates 101, the polyester layers 102, and the honeycomb plate 103 are formed by hot pressing.

[0003] Due to the large difference in physical properties between the carbon fiber plate 101 and the polyester layer 102, the connection strength after hot pressing is low. Under long-term use, the Peak racket 10 is frequently hit by the ball, which can easily cause delamination, resulting in a loose structure, reduced elasticity, and affecting the accuracy and feel of the shot. Summary of the Invention

[0004] The purpose of this invention is to provide a Peak racket with high impact resistance and resistance to delamination, and its manufacturing method, in order to overcome the above-mentioned problems existing in the prior art.

[0005] To achieve the objective, the present invention provides the following technical solution: The anti-detachment layer of the Peak racket of the present invention includes a racket body unit, a reinforcing unit, and a panel unit.

[0006] The aforementioned racket body unit defines a filling space, the filling space having a first opening. The aforementioned reinforcing unit is disposed in the filling space and includes a plurality of fillers, and an encapsulation module covering the plurality of fillers. Each of the aforementioned fillers has a filler body and a covering material covering the filler body. The encapsulation module has an outer peripheral surface connected to the aforementioned racket body unit, and a first end face connected to the aforementioned outer peripheral surface and adjacent to the aforementioned first opening. The aforementioned panel unit includes a first panel connected to one side of the aforementioned racket body unit's first opening and connected to the aforementioned first end face via the first opening, and a second panel connected to the side of the aforementioned racket body unit opposite to the first panel.

[0007] The method for manufacturing the anti-detachment layer Peak racket of the present invention includes an opening step, a reinforcing unit manufacturing step, a filling step, and a bonding step.

[0008] In the hole-making step, a filling space is opened in the center of a first semi-finished product to form a beater unit, and the filling space has a first opening.

[0009] In the reinforcing unit manufacturing step, multiple filling bodies are covered with multiple covering materials to form multiple filling parts, and multiple filling parts are covered with an encapsulation module to form a reinforcing unit whose shape matches the filling space. The encapsulation module has an outer peripheral surface and a first end face connected to the outer peripheral surface.

[0010] In the filling step, the reinforcing unit is embedded into the filling space of the racket body unit to form a second semi-finished product, and the outer peripheral surface of the encapsulation module abuts against the racket body unit, with the first end face adjacent to the first opening.

[0011] In the assembly step, a first panel and a second panel are placed on opposite sides of the second semi-finished product and hot-pressed, so that the beater unit connects the first panel, the second panel, and the outer peripheral surface of the encapsulation module, and the first panel connects to the first end face of the encapsulation module.

[0012] Compared with the prior art, the present invention has the following advantages: The racket body unit, encapsulation module, multiple fillers and the first panel are tightly bonded together by hot pressing, resulting in high impact resistance. The position of the reinforcing unit corresponds to the range of the ball hit. Even when using this anti-delamination Peak racket for a long time, the structure can still remain tight and it is not easy to delaminate. Attached Figure Description

Detailed Implementation

[0026] Specific embodiments of the present invention will now be described with reference to the accompanying drawings. Many details are described below to provide a comprehensive understanding of the invention; however, those skilled in the art will be able to implement the invention without these details.

[0027] See Figure 2 and Figure 3 An embodiment of the anti-detachment layer Peak racket of the present invention includes a racket body unit 1, a reinforcing unit 2, and a panel unit 3.

[0028] See Figure 3 and Figure 4 The racket body unit 1 comprises a first intermediate layer 11, a second intermediate layer 12, and a racket body 13 connecting the first intermediate layer 11 and the second intermediate layer 12. The racket body unit 1 is ring-shaped and defines a filling space 14. The filling space 14 has a first opening 141 formed in the first intermediate layer 11 and a second opening 142 formed in the second intermediate layer 12 opposite to the first opening 141.

[0029] Specifically, the racket body 13 is a honeycomb board made of polypropylene (PP), and the first intermediate layer 11 and the second intermediate layer 12 are made of polyester. Therefore, the racket body unit 1 has high impact resistance and is lightweight. In other variations of this embodiment, the entire racket body unit 1 may also be made of foam.

[0030] The filling space 14 is located in the center of the anti-detachment layer of the Peak racket and corresponds to the area where the ball is easily hit. In this embodiment, the filling space 14 is a perforation through the racket body unit 1, but it is not limited thereto. In other embodiments, the filling space 14 may also be a slot formed on one side of the first intermediate layer 11 of the racket body unit 1, and no second opening 142 is formed on the second intermediate layer 12.

[0031] See Figure 3 and Figure 4 The reinforcing unit 2 is embedded in the filling space 14 and includes multiple filler elements 21, as well as an encapsulation module 22 covering the multiple filler elements 21. Therefore, the position of the reinforcing unit 2 also corresponds to the area where the ball is easily hit. In this embodiment, the first opening 141 and the second opening 142 of the filling space 14 are rectangular, but not limited thereto. In other embodiments, the first opening 141 and the second opening 142 may also be circular, elliptical, polygonal, or other shapes.

[0032] See Figures 5 to 7 Each filler 21 has a filler body 211 and a covering material 212 covering the filler body 211. The filler body 211 is a foam material, and the covering material 212 is a carbon fiber prepreg. In this embodiment, each filler 21 is a cuboid, but it is not limited thereto. In other embodiments, each filler 21 may also be a column of other shapes, such as a cylinder or a triangular prism.

[0033] See Figure 3 and Figure 4The encapsulation module 22 is a hollow cuboid shaped to fit the filling space 14. The encapsulation module 22 has a first end plate 221, a second end plate 222, and a surrounding plate 223. The first end plate 221 is located at the first opening 141, the second end plate 222 is located at the second opening 142 and on the side of the plurality of fillers 21 opposite to the first end plate 221, and the surrounding plate 223 connects the first end plate 221 and the second end plate 222 and surrounds the fillers 21. The first end plate 221 has a first end face 224 adjacent to the first opening 141. The second end plate 222 has a second end face 225 adjacent to the second opening 142. The first end plate 221 and the second end plate 222 are located on opposite sides of the plurality of fillers 21. The first end plate 221, the second end plate 222, and the surrounding plate 223 together define an outer peripheral surface 226 connecting the body 13, the first intermediary layer 11, and the second intermediary layer 12. The first end face 224 of the first end plate 221 and the second end face 225 of the second end plate 222 are connected to the outer peripheral surface 226. Multiple fillers 21 are arranged in an array within the encapsulation module 22.

[0034] Specifically, the first end plate 221, the second end plate 222, and the surrounding plate 223 are carbon fiber plates.

[0035] The panel unit 3 includes a first panel 31 and a second panel 32. The first panel 31 is connected to the side of the first intermediate layer 11 opposite to the racket body unit 1, and the second panel 32 is connected to the side of the second intermediate layer 12 opposite to the racket body unit 1. The first panel 31 is connected to the first end face 224 of the first end plate 221 via a first opening 141. The second panel 32 is connected to the second end face 225 of the second end plate 222 via a second opening 142.

[0036] Specifically, the first panel 31 and the second panel 32 are carbon fiber plates, and the first panel 31, the second panel 32, the first end plate 221, and the second end plate 222 are parallel to each other. Therefore, the fiber directions of the first panel 31, the second panel 32, the first end plate 221, and the second end plate 222 are also parallel to each other. This ensures that when the first panel 31 or the second panel 32 is impacted, the fiber directions of the first panel 31, the second panel 32, the first end plate 221, and the second end plate 222 are maintained, so that the Peak racket with anti-detachment layer does not produce an uneven racket surface.

[0037] See Figure 8 The method for manufacturing the anti-detachment layer Peak racket of the present invention includes a racket body preparation step S1, an opening step S2, a reinforcing unit fabrication step S3, a filling step S4, and a bonding step S5.

[0038] See Figure 9In the paddle body preparation step S1, a first intermediate layer 11 and a second intermediate layer 12 are respectively bonded to two opposite sides of a paddle body 13 to form a first semi-finished product 4.

[0039] See Figure 9 and Figure 10 In the hole-making step S2, according to the required reinforcement range, a hole is milled in the center of the first semi-finished product 4 and a filling space 14 is formed to create a beater unit 1. The filling space 14 has a first opening 141 formed in the first intermediate layer 11 and a second opening 142 formed in the second intermediate layer 12.

[0040] See Figures 5 to 7 In step S3 of the reinforcement unit fabrication, multiple filler bodies 211 are covered by multiple covering materials 212 to form multiple filler elements 21 (only one filler element 21 is shown in the figure for explanation). The covering material 212 is a carbon fiber prepreg. See also Figure 3 and Figure 4 Multiple filler elements 21 are tightly filled between the first end plate 221, the second end plate 222, and the surrounding plate 223, and arranged in an array abutting against each other to form a reinforcing unit 2 whose shape matches the filling space 14. In this embodiment, the filler body 211 is a foamed material. In other embodiments, the filler body 211 can also be unfoamed plastic, which is heated and foamed through the hot pressing process in the following bonding step S5 to form a foamed material. Therefore, the material of the filler body 211 has a high selectivity, and there is no need to make a foamed material first, which can simplify the manufacturing process and reduce manufacturing costs. The first end plate 221, the second end plate 222, and the surrounding plate 223 are carbon fiber plates.

[0041] See Figure 10 and Figure 11 In the filling step S4, the reinforcing unit 2 is embedded into the filling space 14 to form a second semi-finished product 5, and the outer peripheral surface 226 of the encapsulation module 22 abuts against the body 13, the first intermediary layer 11 and the second intermediary layer 12, so that the first end face 224 of the first end plate 221 is adjacent to the first opening 141, and the second end face 225 of the second end plate 222 is adjacent to the second opening 142.

[0042] See Figure 11 and Figure 12In step S5, the first panel 31 and the second panel 32 are placed on opposite sides of the second semi-finished product 5 and hot-pressed, so that the first end plate 221, the second end plate 222, the surrounding plate 223 of the encapsulation module 22 are tightly connected to the multiple fillers 21. The first panel 31 is connected to the first end face 224 of the first intermediary layer 11 and the first end plate 221, the second panel 32 is connected to the second end face 225 of the second end plate 222 of the second intermediary layer 12, and the outer peripheral surface 226 of the encapsulation module 22 is connected to the racket body 13, the first intermediary layer 11, and the second intermediary layer 12. The first end plate 221, the second end plate 222, and the surrounding plate 223 can prevent the multiple fillers 21 from being squeezed by the racket body 13, the first intermediary layer 11, the second intermediary layer 12, the first panel 31, and the second panel 32 when they expand during hot pressing, so that the entire Peak racket with anti-detachment layer remains flat and the racket surface is not uneven.

[0043] Since the first end plate 221, the second end plate 222, the first front panel 31, and the second front panel 32 are all made of carbon fiber, and the covering material 212 covering the filling body 211 is made of carbon fiber prepreg, it indicates that the materials of all interconnected components within this anti-detachment Peak racket contain carbon fiber, resulting in minimal differences in physical properties, high connection strength after hot pressing, and high impact resistance. Furthermore, the filling body 211 is made of foam material, which absorbs impact and improves the feel.

[0044] In summary, the anti-delamination Peak racket of the present invention has a filling space 14 in the racket body unit 1 and a reinforcing unit 2 embedded therein, and then the racket body unit 1, the reinforcing unit 2 and the first panel 31 are joined by heat pressing. Because the racket body unit 1, the encapsulation module 22, the multiple fillers 21 and the first panel 31 are tightly bonded together by heat pressing, the impact resistance is high, and the position of the reinforcing unit 2 corresponds to the hitting range. Even when using the anti-delamination Peak racket for a long time, the structure can still maintain a tight structure and is not prone to delamination. Therefore, the purpose of the present invention is indeed achieved.

[0045] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
