DETAILED DESCRIPTION

[0032] In order to provide a further understanding of the present invention, preferred embodiments are listed and described in detail with reference to the accompanying drawings as follows:

[0033] The present invention provides a pickleball racket with a centralized core. The present invention uses a pickleball racket as an embodiment, but the pickleball racket can also be used to manufacture rackets of different sizes, such as a table tennis paddle or a beach paddle.

[0034] Please also see Figures 2 to 5 The pickleball racket 10 of the first embodiment includes a plate body 20 and a grip body 30. The plate body 20 includes a core 21 and a frame 22. The frame 22 is disposed around the core 21. The plate body 20 defines a first hitting response portion 21A and a second hitting response portion 21B adjacent to each other corresponding to the core 21. The plate body 20 defines a third hitting response portion 22A corresponding to the frame 22, wherein:

[0035] The first hitting response portion 21A is located in the central part of the core 21, which is the so-called "sweet spot" for the best hitting response. Figure 2 The axis and its vicinity are used as reference.

[0036] The second hitting response portion 21B is located away from the central portion of the core 21, or the second hitting response portion 21B is partially located in the central portion of the core 21, and the second hitting response portion 21B is partially located away from the central portion of the core 21. The second hitting response portion 21B is used to limit the first hitting response portion 21A, so that the first hitting response portion 21A is concentrated in the central portion of the core 21. In this way, the core 21 is easy to deform by combining the first hitting response portion 21A and the second hitting response portion 21B, and the deformation comes from reducing stiffness, increasing deflection, increasing flexion, and reducing the coefficient of restitution (COR).

[0037] One embodiment of the second hitting response portion 21B is located at two sides of the first hitting response portion 21A, or another embodiment of the second hitting response portion is located around the first hitting response portion, but is not limited to the above disclosed embodiments.

[0038] The first hitting response part 21A has a first response parameter, the second hitting response part 21B has a second response parameter, and the third hitting response part 22A has a third response parameter, and they can be made of different materials. The second hitting response part 21B and the third hitting response part 22A can be made of the same material. In the above, each response parameter can be stiffness, but is not limited to stiffness (for example, one of the deflection, buckling and restitution coefficient related to stiffness or a combination thereof).

[0039] Taking the core 21 with different stiffness as an example, the stiffness of the first hitting response part 21A is greater than the stiffness of the second hitting response part 21B and the stiffness of the third hitting response part 22A as an embodiment. When the ball is hit by the first hitting response part 21A, the time the pickle ball stays on the racket is short, which is not conducive to controlling the rotation force of the board 20 on the pickle ball. On the contrary, when the ball is hit by the second hitting response part 21B and the third hitting response part 22A, the time the pickle ball stays on the racket is long, which is conducive to controlling the rotation force of the board 20 on the pickle ball. In this way, the user can select one of the first hitting response part 21A, the second hitting response part 21B and the third hitting response part 22A according to different hitting strategies.

[0040] This first ball striking response part 21A is further provided with a plurality of first components 21A1 in the shape of a polygonal column, a cylinder, a semi-cylindrical column, an arc column or a deformation of the aforementioned column. The first component 21A1 has a first response parameter. These first components 21A1 are arranged with each other. Any first component 21A1 extends between corresponding frame edges of the frame 22. Among them, these first components 21A1 are arranged longitudinally with each other as one embodiment, or these first components are arranged transversely with each other as another embodiment, or these first components are arranged diagonally with each other as another embodiment, but are not limited to one or a combination of the longitudinal arrangement, transverse arrangement and diagonal arrangement disclosed above.

[0041] Each first component 21A1 is made of one of a honeycomb structure and a rib structure, but is not limited thereto. The honeycomb structure can be referred to in US Pat. No. US20180104555A1. Figure 1 As shown, the rib structure can refer to US Patent Publication No. US10377093B2. Figure 7As shown, the aforementioned patent is only for reference and is not used to limit the first component 21A1. In addition, each first component 21A1 is made of one selected from carbon fiber material, hard plastic material and hard foam material, but is not limited thereto.

[0042] The second ball striking response portion 21B is further provided with a second component 21B1 in a polygonal shape, the second component 21B1 having a second response parameter, and the second component 21B1 is made of one of polyethylene (PE) and ethylene-vinyl acetate copolymer (EVA), but not limited thereto. In addition, the first component 21A1 of the first ball striking response portion 21A and the second component 21B1 of the second ball striking response portion 21B are interchangeable, that is, the first component 21A1 or the second component 21B1 can be used as the first ball striking response portion 21A or the second ball striking response portion 21B to meet the needs of the user.

[0043] The frame 22 has a third response parameter. The frame 22 is made of one selected from polyethylene and ethylene-vinyl acetate copolymer, but is not limited thereto.

[0044] Therefore, the first response parameter of the first hitting response part 21A is stiffness and the second response parameter of the second hitting response part 21B is stiffness, which respectively depends on the first component 21A1 and the second component 21B1 being made of different materials with different stiffness to correspond to the first response parameter and the second response parameter. The second response parameter of the second hitting response part 21B is stiffness and the third response parameter of the third hitting response part 22A is stiffness, which respectively depends on the second component 21B1 and the frame 22 being made of the same material with the same stiffness to correspond to the second response parameter and the third response parameter.

[0045] The present invention uses as one embodiment a first response parameter of the first component 21A1 of the first ball hitting response portion 21A having a stiffness greater than a second response parameter of the second component 21B1 of the second ball hitting response portion 21B, or uses as a second embodiment a first response parameter of the first component 21A1 of the first ball hitting response portion 21A having a stiffness less than a second response parameter of the second component 21B1 of the second ball hitting response portion 21B, but is not limited to the embodiments disclosed above.

[0046] The area of ​​the first hitting response part 21A and the area of ​​the second hitting response part 21B of the present invention are determined according to the needs of the user. For example, if the demand is for a pickle ball racket 10 with high rigidity, the first hitting response part 21A with large area and high rigidity can be selected as one embodiment. Conversely, if the demand is for a pickle ball racket 10 with low rigidity, the second hitting response part 21B with large area and low rigidity can be selected as the second embodiment, but it is not limited to the embodiments disclosed above.

[0047] The plate body 20 further includes two surface layers 23 spaced apart from each other, each surface layer 23 is respectively assembled on the core 21 and the frame 22, and each surface layer 23 is further respectively assembled on the first component 21A1 of the first hitting response part 21A, the second component 21B1 of the second hitting response part 21B, and the frame 22 of the third hitting response part 22A, so that each surface layer 23 corresponds to the first hitting response part 21A, the second hitting response part 21B, and the third hitting response part 22A. The two surface layers 23 are made of one of a carbon fiber and a glass fiber, but are not limited thereto.

[0048] The first hitting response part 21A, the second hitting response part 21B and the third hitting response part 22A are used to create the unique functions of the pickle ball racket 10 based on the unique hitting attributes of the user. In this way, the present invention alternately uses different hitting response parts according to the hitting strategy, so as to control the time that the pickle ball stays on the board 20 and also to control the rotation force of the board 20 on the pickle ball.

[0049] The grip body 30 is formed from the bottom side of the frame 22 of the plate body 20, and can be formed by longitudinal extension or longitudinal connection. Figure 2 The arrow direction is used as a reference. The grip body 30 and the board body 20 can be made of the same material or different materials. The width and thickness of the grip body 30 are different from those of the board body 20, which is a change made to allow the user to hold it comfortably. The grip body 30 is further assembled with a handle 31. The further embodiment of the aforementioned assembly is a sleeve, but not limited to a sleeve. The handle 31 is selected from a synthetic rubber, but not limited to this. The handle 31 allows the user to control the board body 20 more stably.

[0050] Please also see Figures 6 to 9 The difference between the second embodiment and the first embodiment lies in the first hitting response part 21A. The first hitting response part 21A of the second embodiment further defines at least two response blocks 21A2 adjacent to each other. There is further a segmented gap 21A3 between any two response blocks 21A2. The size of the segmented gap 21A3 depends on the density or sparseness of the arrangement of any two response blocks 21A2. Each response block 21A2 is provided with these first components 21A1. This segmented gap 21A3 is further provided with a filling piece 21A4. This filling piece 21A4 has an elastic coefficient. The size of the elastic coefficient depends on the needs of the user. Different elastic coefficients will cause changes in the hitting sound. This filling piece 21A4 is further a rubber band with this elastic coefficient.

[0051] The descriptions such as “first”, “second” and “third” mentioned in the present invention are used for distinction and do not represent the order of precedence.

[0052] In summary:

[0053] The core 21 of the present invention is easy to deform through the combination of the first hitting response part 21A and the second hitting response part 21B. The deformation comes from the reduction of stiffness, the increase of deflection, the improvement of buckling, and the reduction of the recovery coefficient, which is beneficial to control the time that the pickle ball stays on the board body 20, and is also beneficial to control the rotational force of the board body 20 on the pickle ball.

[0054] The present invention provides different first hitting response parts 21A, second hitting response parts 21B and third hitting response parts 22A, and has different material combinations, so as to avoid purchasing multiple rackets and reduce the cost burden of rackets.

[0055] The present invention uses different first hitting response parts 21A, second hitting response parts 21B and third hitting response parts 22A alternately according to different hitting strategies, flexibly controls the racket face, meets the needs of users, and seizes the winning opportunity.

[0056] Finally, the above-disclosed embodiments are not intended to limit the present invention. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all of them can be protected by the present invention.
