Detailed Description

So that the utility model can be further understood, a preferred embodiment will now be described in conjunction with the accompanying drawings, in which:

the utility model provides a picocell racket with a centralized core, which is taken as an embodiment, but the picocell racket can also be suitable for manufacturing rackets with different sizes, such as a table racket (Table Tennis Paddle) or a Beach racket (Beach Paddle).

Referring to fig. 2 to 5, the racquet 10 of the first embodiment includes a plate 20 and a grip 30, the plate 20 includes a core 21 and a frame 22, and the frame 22 is disposed on a peripheral side of the core 21. The plate 20 defines a first ball striking response portion 21A and a second ball striking response portion 21B adjacent to each other corresponding to the core 21, and the plate 20 defines a third ball striking response portion 22A corresponding to the frame 22, wherein:

the first striking response portion 21A is located in the central portion of the core 21, the so-called "sweet spot" being the optimal striking response portion. The central portion is referenced to the axis of fig. 2 and its vicinity.

The second ball striking response portion 21B is located away from the central portion of the core 21, or the second ball striking response portion 21B is located partially at the central portion of the core 21, the second ball striking response portion 21B being located partially at the central portion of the core 21. The second ball striking response portion 21B serves to narrow the first ball striking response portion 21A such that the first ball striking response portion 21A is concentrated at the central portion of the core 21. By this, the core 21 is easily deformed by coupling the first ball striking response portion 21A and the second ball striking response portion 21B, and the deformation is derived from lowering Stiffness (Stiffness), increasing Deflection (Deflection), raising buckling (Flexion), and lowering the coefficient of restitution (Coefficient of Restitution, COR).

One embodiment of the second ball striking response portion 21B is located at both sides of the first ball striking response portion 21A, or two embodiments of the second ball striking response portion are located at the periphery of the first ball striking response portion, but not limited to the above disclosed embodiments.

The first ball striking response portion 21A and the second ball striking response portion 21B each have a first response parameter and the third ball striking response portion 22A has a second response parameter, and the second ball striking response portion 21B and the third ball striking response portion 22A may be made of different materials from each other, and the second ball striking response portion 21B and the third ball striking response portion 22A may be made of the same material from each other.

Taking the core 21 with different rigidities as an example, the rigidity of the first ball striking response portion 21A is greater than the rigidity of the second ball striking response portion 21B and the rigidity of the third ball striking response portion 22A are taken as an example. When the ball is hit by the first ball striking responding section 21A, the time for which the picoball stays in the racket is short, which is disadvantageous for the control panel body 20 to rotate the picoball. Conversely, when the ball is hit by the second ball striking response portion 21B and the third ball striking response portion 22A, the picoball stays in the racket for a long time, which is advantageous for controlling the rotational force of the board body 20 to the picoball. Thus, the user can select one of the first ball striking response portion 21A, the second ball striking response portion 21B and the third ball striking response portion 22A according to different ball striking strategies.

The first ball striking response portion 21A further includes a plurality of first elements 21A1 having a polygonal pillar shape, a semi-pillar shape, an arc shape, or a deformation of the pillar shape, the first elements 21A1 have a first response parameter, the first elements 21A1 are arranged with each other, any one of the first elements 21A1 extends between a corresponding rim of the frame 22, wherein the first elements 21A1 are longitudinally arranged with each other as an embodiment thereof, or the first elements are transversely arranged with each other as another embodiment, or the first elements are diagonally arranged with each other as another embodiment thereof, but not limited to the longitudinal arrangement, the transverse arrangement, the diagonal arrangement, or the combination thereof.

In addition, each first component 21A1 is made of one selected from carbon fiber material, hard plastic material and hard foam material, but not limited thereto.

The second striking responding portion 21B further has a second member 21B1 having a polygonal shape, the second member 21B1 has a second response parameter, and the second member 21B1 is made of one selected from Polyethylene (PE) and ethylene-vinyl acetate copolymer (Ethylene Vinyl Acetate, EVA), but not limited thereto. In addition, the first member 21A1 of the first ball striking response portion 21A and the second member 21B1 of the second ball striking response portion 21B may be interchangeable, that is, the first member 21A1 or the second member 21B1 may be used as the first ball striking response portion 21A or the second ball striking response portion 21B to meet the user's needs.

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

Accordingly, the first response parameter of the first ball striking response portion 21A is stiffness and the second response parameter of the second ball striking response portion 21B is stiffness that depends on the first member 21A1 and the second member 21B1 being made of different materials to each other to correspond to the first response parameter and the second response parameter, respectively, the second response parameter of the second ball striking response portion 21B is stiffness and the third response parameter of the third ball striking response portion 22A is stiffness that depends on the second member 21B1 and the frame 22 being made of the same material to each other to correspond to the second response parameter and the third response parameter, respectively.

The present utility model is to take the first response parameter of the first component 21A1 of the first ball striking response portion 21A as an example of the stiffness being greater than the second response parameter of the second component 21B1 of the second ball striking response portion 21B, or take the first response parameter of the first component 21A1 of the first ball striking response portion 21A as the stiffness being less than the second response parameter of the second component 21B1 of the second ball striking response portion 21B as two examples of the stiffness, but is not limited to the above disclosed examples.

The area of the first ball striking response portion 21A and the area of the second ball striking response portion 21B of the present utility model depend on the user's requirement, for example, the requirement is that the pith racket 10 with large stiffness is selected as one embodiment thereof, whereas the requirement is that the pith racket 10 with small stiffness is selected as two embodiments thereof, namely, the second ball striking response portion 21B with large area and small stiffness is selected as two embodiments thereof, but is not limited to the above disclosed embodiments.
