[0027] 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:

[0028] The present invention provides a pickleball racket with a segmented 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.

[0029] Please also see Figures 2 to 5 The pickle ball racket 10 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, wherein:

[0030] The core 21 defines at least two adjacent hitting response parts 21A. The present invention uses five hitting response parts 21A as an embodiment, but is not limited to the number disclosed above. A segment gap 21B is further formed between any two hitting response parts 21A. The size of the segment gap 21B depends on the density or sparseness of the arrangement of any two hitting response parts 21A.

[0031] Thus, the core 21 is easy to deform by combining the hitting response parts 21A and the segmented gaps 21B between the hitting response parts 21A. The deformation comes from reducing stiffness, increasing deflection, improving flexion, and lowering the coefficient of restitution (COR). This is beneficial for controlling the time that the pickle ball stays on the board 20, and also for controlling the rotational force of the board 20 on the pickle ball.

[0032] When the number of the segmented gaps 21B is 2 or more, the forming directions of any two segmented gaps 21B are selected from intersecting and non-intersecting directions or a combination thereof, and the forming direction is based on the arrow direction X in the accompanying drawings as a reference.

[0033] Each ball striking response part 21A is further provided with a plurality of components 21A1 in the shape of a polygonal column, a cylindrical column, a semi-cylindrical column, an arc column or a deformation of the aforementioned column. The component 21A1 has a first response parameter, which is stiffness, but is not limited to stiffness (for example, one or a combination of deflection, buckling and coefficient of restitution related to stiffness). These components 21A1 are arranged with each other, and any component 21A1 extends between corresponding frame edges of the frame 22, wherein these components 21A1 are arranged longitudinally with each other as one embodiment, or these components are arranged transversely with each other as another embodiment, or these components are arranged obliquely with each other as another embodiment, but are not limited to one or a combination of the longitudinal arrangement, transverse arrangement and oblique arrangement disclosed above.

[0034] There is further a component gap 21A2 between any two components 21A1 , and the size of the component gap 21A2 depends on the density or sparseness of the arrangement of any two components 21A1 .

[0035] Each 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 Patent Publication No. US20180104555A1. Figure 1 As shown, the rib structure can refer to US Patent Publication No. US10377093B2. Figure 7 As shown, the aforementioned patent is only for reference and is not used to limit the components 21A1. In addition, each component 21A1 is made of one of carbon fiber materials, hard plastic materials and hard foam materials, but is not limited thereto.

[0036] The frame 22 has a second response parameter, which is stiffness, but is not limited to stiffness (such as one or a combination of deflection, buckling and coefficient of restitution related to stiffness). The frame 22 is made of one selected from polyethylene (PE) and ethylene-vinyl acetate copolymer (EVA), but is not limited thereto.

[0037] Therefore, the first response parameter of component 21A1 and the second response parameter of frame 22 are different from each other, and further, they are made of different materials with different stiffness. The present invention takes the first response parameter of component 21A1 being greater than the second response parameter of frame 22 as an embodiment, that is, the stiffness of component 21A1 is greater than the stiffness of frame 22 as an embodiment, but is not limited to the embodiments disclosed above.

[0038] 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 component 21A1 of the hitting response part 21A of the core 21 and the frame 22. The two surface layers 23 are made of one of a carbon fiber and a glass fiber, but are not limited thereto.

[0039] The grip 30 is formed from the bottom side of the frame 22 of the board 20, and can be formed by longitudinal extension or longitudinal connection. The longitudinal direction is the arrow direction Y in the figure as a reference. The grip 30 and the board 20 can be made of the same material or different materials. The width and thickness of the grip 30 are different from those of the board 20, which is a change made to allow the user to hold it comfortably.

[0040] The grip body 30 is further provided with a grip 31 . The further embodiment of the aforementioned provision is a sleeve, but is not limited to a sleeve. The grip 31 is made of a synthetic rubber, but is not limited to this. The grip 31 allows the user to control the board body 20 more stably.

[0041] The segment gap 21B of the core 21 (see Figure 6 ) is further provided with a filling piece 21B1, and the filling piece 21B1 has an elastic coefficient, and the size of the elastic coefficient depends on the needs of the user. Different elastic coefficients will cause the sound of hitting the ball to change. The filling piece 21B1 is further a rubber band with this elastic coefficient.

[0042] See also Figure 7The difference between the second embodiment and the first embodiment is that in the first hitting response part 21A, the number of components 21A1' of each hitting response part 21A can be 1, and the components 21A1' do not need to be arranged with each other. Moreover, each hitting response part 21A can be provided with one or a combination of components 21A1 and 21A1'. Any two adjacent components 21A, 121A1' are made of one selected from a honeycomb structure (Honeycomb structure) and a rib structure (Rib structure), but not limited thereto. Any two adjacent components 21A, 121A1' are made of one selected from a carbon fiber material, a hard plastic material and a hard foam material, but not limited thereto.

[0043] The descriptions such as “first” and “second” mentioned in the present invention are used for distinction and do not represent the order of precedence.

[0044] In summary:

[0045] The core 21 of the present invention is easy to deform through the combination of the hitting response part 21A and the segmented gap 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 20, and also helps to control the rotational force of the board 20 on the pickle ball.

[0046] 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.
