Description

Technical Field

[0001] This utility model relates to the technical field of table tennis rackets, and in particular to an asymmetric fiber structure table tennis racket and racket. Background Technology

[0002] Table tennis is a popular sport with many athletes and enthusiasts. Players usually use forehand and backhand to hit the ball. However, there are significant differences between forehand and backhand techniques. Forehand usually involves more power and is more aggressive, requiring more elasticity and power from the racket. Backhand, on the other hand, usually involves relatively softer power, focuses more on defense and transition, and requires a more balanced racket performance.

[0003] Table tennis blades are typically made of a symmetrical structure, consisting of a surface layer (upper and lower surfaces), a core layer (the middle layer, which may be single or multi-layered), and a power layer (the layer of wood between the surface and core). Currently, table tennis blades rely solely on different forehand and backhand sponges and rubbers to adjust performance; however, this adjustment range is too small to meet the technical requirements of modern table tennis balls with diameters greater than 40mm. Some blades use different wood thicknesses or types on the core layer to create different forehand and backhand elasticity. These blades do not contain synthetic fibers. Because different woods have different properties, asymmetrical combinations can easily lead to an imbalance of internal stress on both sides of the blade. Without the counterbalancing effect of synthetic fibers, the natural wood can easily warp and bend to one side over time, rendering the blade unusable. Some double-layer asymmetrical table tennis blades do not exhibit significant performance differences between their two sides, with almost no difference in the number of fiber layers. This results in relatively small performance differences. However, modern table tennis techniques are increasingly resembling tennis, involving greater force and deeper penetration into the blade's core. The aforementioned structures are insufficient to support this change. Therefore, there is an urgent need to develop an asymmetrical fiber table tennis blade to allow for greater performance differences between the forehand and backhand sides. Utility Model Content

[0004] The purpose of this invention is to provide an asymmetric fiber structure table tennis board and racket to solve the problems existing in the prior art and make the performance difference between the forehand and backhand sides of the racket greater.

[0005] To achieve the above objectives, this utility model provides the following solution:

[0006] This utility model provides an asymmetric fiber structure table tennis board, including a core material layer, a surface material layer and a force material layer. The force material layer and the surface material layer are sequentially arranged on both sides of the core material layer to form a table tennis board. At least one side of the thickness center surface of the table tennis board is provided with a fiber layer, and the number of fiber layers arranged on both sides of the thickness center surface is different.

[0007] Preferably, the fiber layer is located between the force material layer and the face material layer and / or between the core material layer and the force material layer.

[0008] Preferably, the surface material layer is the fiber layer.

[0009] Preferably, the core material layer and the face material layer are bonded together, as are the face material layer and the force material layer, and the fiber layer is also bonded to the core material layer, the face material layer, and the force material layer.

[0010] Preferably, the fiber layer includes several different sizes with varying thicknesses, each not exceeding 1 mm.

[0011] Preferably, the fiber layer is made of natural fibers and man-made fibers; the man-made fibers include any one of carbon fibers, aramid fibers, carbon aramid fibers, metal fibers or glass fibers, and the natural fibers include any one of wood or bamboo fibers.

[0012] Preferably, the fiber layers of each layer are made of the same or different materials, and the fiber layers of each layer are made of the same or different materials.

[0013] Preferably, the core material layer or the force material layer is provided with at least one layer; when the core material layer or the force material layer is at least two layers, the interlayer is an adhesive layer or a fiber layer; the materials of the core material layer, the surface material layer and the force material layer all include at least one of natural wood, dyed wood or engineered wood.

[0014] Preferably, the total thickness of the ping-pong paddle is no more than 10 mm, and the thickness of the core material layer is no more than 6 mm.

[0015] This utility model also includes an asymmetric fiber structure table tennis racket, comprising the aforementioned asymmetric fiber structure table tennis board, a sponge layer, and a rubber layer, wherein the sponge layer and the rubber layer are sequentially bonded to both sides of the asymmetric fiber structure table tennis board.

[0016] The present invention achieves the following technical advantages over the prior art:

[0017] The ping-pong paddle comprises a core layer, a surface layer, and a force layer. Force and surface layers are sequentially arranged on both sides of the core layer to form the paddle. At least one side of the thickness center surface of the paddle has a fiber layer, and the number of fiber layers on each side of the thickness center surface is different. This invention provides a highly asymmetric fiber ping-pong paddle. By increasing the number and thickness of the fiber layers on the forehand and backhand sides of the paddle, and by differentiating the types of materials, the paddle exhibits greater performance differences on both sides, is less prone to deformation, and can better support new material ping-pong balls with a diameter ≥40mm, leading to a trend towards more powerful shots.

[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] like Figures 1 to 3 As shown, this embodiment provides an asymmetric fiber structure ping-pong board, including a core layer 1, a surface layer 3, and a force layer 2. Force layers 2 and surface layers 3 are sequentially arranged on both sides of the core layer 1 to form the ping-pong board. At least one side of the thickness center plane of the ping-pong board has a fiber layer 4, and the number of fiber layers 4 on both sides of the thickness center plane is different, including 2 fiber layers 4 on one side and 1 fiber layer 4 on the other side; or 2 fiber layers 4 on one side and 0 fiber layers 4 on the other side; or 1 fiber layer 4 on one side and 0 fiber layers 4 on the other side, etc. In this embodiment, by increasing the difference in the number of fiber layers 4 on both sides of the ping-pong board, the internal stress balance of the natural wood is more effective, and the overall rigidity of the board is also enhanced, making it more suitable for hitting techniques with new material ping-pong balls with a diameter ≥40mm.

[0030] As an alternative, in this embodiment, the fiber layer 4 is located between the force layer 2 and the face layer 3 and / or between the core layer 1 and the force layer 2, thereby restraining the internal stress of the wood core layer 1, face layer 3 and force layer 2.

[0031] As an optional solution, in this embodiment, the core material layer 1 and the face material layer 3 are bonded together, as are the face material layer 3 and the force material layer 2. The fiber layer 4 is also bonded to the core material layer 1, the face material layer 3 and the force material layer 2.

[0032] As an optional solution, in this embodiment, the fiber layer 4 includes several sizes with different thicknesses, all of which do not exceed 1 mm. The greater the thickness of the fiber layer 4, the greater the stiffness and strength of the ping-pong paddle.

[0033] As an optional solution, the fiber layer 4 in this embodiment is made of both natural and synthetic fibers. Synthetic fibers include any one of carbon fiber, aramid fiber, carbon aramid fiber, metal fiber, or glass fiber, while natural fibers include any one of wood or bamboo fiber. Since common natural fibers are less strong than synthetic fibers, and the development trend of table tennis requires stronger blade rigidity, this embodiment preferably utilizes the differences in synthetic fiber materials to create asymmetrical properties on both sides of the table tennis blade. This allows the synthetic fiber material to counteract the internal stress of the natural wood, reducing the probability of blade deformation.

[0034] As an optional solution, in this embodiment, the fiber layers 4 may be made of the same or different materials, and the thickness of each fiber layer 4 may be the same or different. In this embodiment, the stiffness and elasticity requirements of different types of table tennis blades can be met by adjusting the thickness, material, and number of fiber layers 4.

[0035] As an optional solution, in this embodiment, both the core material layer 1 and the force material layer 2 are provided with at least one layer; when the core material layer 1 or the force material layer 2 is at least two layers, the interlayer is an adhesive layer or a fiber layer 4.

[0036] As an alternative, in this embodiment, the core layer 1, the surface layer 3, and the force layer 2 are all made of at least one of natural wood, stained wood, or engineered wood. In this embodiment, fiber materials are used to counteract the internal stress of the natural wood.

[0037] As an optional solution, in this embodiment, the total thickness of the ping-pong paddle does not exceed 10mm, and the thickness of the core material layer 1 does not exceed 6mm, ensuring the overall lightweight nature of the ping-pong paddle.

[0038] In this embodiment, the highly asymmetric fiber table tennis board increases the number and thickness of the fiber layers 4 on both the forehand and backhand sides of the board, and the material types are different. This makes the performance difference between the two sides of the board greater, less prone to deformation, and better able to support the development of new material table tennis balls with a diameter ≥40mm towards a stronger power trend.

[0039] Example 2

[0040] like Figure 1As shown, in this embodiment, the fiber layer 4 on one side of the thickness center surface of the table tennis blade is located between the force material layer 2 and the surface material layer 3, and between the core material layer 1 and the force material layer 2, respectively. The fiber layer 4 on the other side of the thickness center surface is located between the force material layer 2 and the surface material layer 3. This is equivalent to having two fiber layers 4 on one side of the thickness center surface of the table tennis blade and one fiber layer 4 on the other side. This results in a different number of fiber layers 4 on both sides of the thickness center surface of the table tennis blade, thus creating different stiffness and elasticity on both sides to adapt to the different needs of forehand and backhand shots in table tennis. In this embodiment, the difference in the number of fiber layers 4 on both sides of the thickness center surface reaches 2vs1, which can significantly increase the difference in performance between the two sides. This is relatively more suitable for players who use inverted rubber on both sides. Both sides need a certain offensive capability and need to use artificial fibers to improve the rigidity of the blade. The backhand is more stable and the forehand is faster. At the same time, it enhances the overall adaptability of the blade to the new material table tennis era with a diameter ≥40mm.

[0041] Example 3

[0042] like Figure 2 As shown, in this embodiment, the fiber layers 4 on one side of the thickness center plane of the table tennis blade are located between the force material layer 2 and the surface material layer 3, and between the core material layer 1 and the force material layer 2, respectively. No fiber layers 4 are provided on the other side of the thickness center plane. This is equivalent to having two fiber layers 4 on one side of the thickness center plane and zero fiber layers 4 on the other side, resulting in different numbers of fiber layers 4 on both sides of the thickness center plane. This leads to different stiffness and elasticity on both sides, adapting to the different needs of forehand and backhand strokes in table tennis. In this embodiment, the difference in the number of fiber layers 4 on both sides of the thickness center plane is even greater, reaching 2 vs 0, or even greater, significantly increasing the performance difference between the two sides and enhancing the overall technical adaptability of the blade to new material table tennis balls with a diameter ≥ 40mm.

[0043] Assuming the fiber type and thickness of each layer are the same, the forehand and backhand performance difference shown in this embodiment is the greatest, making this type of blade more suitable for players with vastly different forehand and backhand techniques. For example, some blades have short pips on one side and long pips on the other (short pips on the side with fiber layer 4 and long pips on the side without fiber layer 4). The short pips side is suitable for fast attacks, while the long pips side is almost entirely for defensive play and deflection, making it very suitable for players with such vastly different forehand and backhand techniques.

[0044] Example 4

[0045] like Figure 3As shown, in this embodiment, the surface layer 3 of the ping-pong paddle is a fiber layer 4. This means that one side of the thickness center plane of the ping-pong paddle has one fiber layer 4, and the other side has zero fiber layers 4. This difference in the number of fiber layers 4 on both sides of the thickness center plane results in different stiffnesses on both sides, adapting to the different needs of forehand and backhand shots in ping-pong. When the difference in the number of fiber layers 4 on both sides of the thickness center plane is 1 vs 0, this embodiment allows the artificial fibers to directly serve as the surface layer 3, thus exerting their effect more directly than simply having them below the surface layer 3, resulting in faster shot speed.

[0046] Example 5

[0047] This embodiment provides an asymmetric fiber structure table tennis racket, including any one of the asymmetric fiber structure table tennis blades in Embodiments 1 to 4 above, a sponge layer, and a rubber layer. Both sides of the asymmetric fiber structure table tennis blade are sequentially bonded with a sponge layer and a rubber layer.
