Description

Technical Field

[0001] The utility model relates to the field of table tennis racket improvement, in particular to a table tennis racket with an asymmetric racket handle. Background Art

[0002] The traditional table tennis racket structure includes a racket face with an elastic surface and a racket handle connected to the racket face. The root transition section where the racket face and the racket handle connect is a sloped surface that transitions to the racket face. Among them, the horizontal grip is the most basic grip method in table tennis. The corresponding table tennis racket handle is mostly a waist handle or a straight handle, such as Figure 1 and Figure 2 As shown, whether it is a waisted handle or a straight handle, the existing table tennis racket is symmetrical left to right and front to back, and the surface of the handle is almost all a smooth arc surface.

[0003] When hitting a table tennis ball, Figure 3 As shown, the thumb and other four fingers of the racket hand of the racket holder are respectively wrapped around the two sides of the racket handle and gripped tightly. In order to accurately and flexibly control the racket to hit the ball, the index finger is usually naturally vertically placed on the back of the racket face, so that the thumb, middle finger, ring finger and little finger are used to grasp the racket, and the index finger can play the role of pressing the racket. When holding a table tennis racket, either the backhand or the forehand is advantageous. Among them, the backhand advantage refers to the gripping method that is most conducive to backhand power, and the forehand advantage refers to the gripping method that is most conducive to forehand power.

[0004] However, it's not possible to have both backhand and forehand advantages. When hitting balls coming from different angles, it's often necessary to switch between forehand and backhand, meaning the racket must be rotated through an angle. However, due to the extremely high speed of table tennis itself, the time it takes to switch between forehand and backhand, while still hitting the ball quickly, is insufficient. This means that the speed of a player's forehand-backhand transitions can't keep up with the tempo of play, a problem even experienced by top players. Consequently, many players choose a compromise based on their individual circumstances. For example, when in a backhand advantage, the angle of transition to the forehand is minimized. This reduces the quality of the forehand return, even though it doesn't reach the optimal forehand power position (i.e., the forehand advantage). This speed is called swing speed in table tennis, and swing speed conflicts with simultaneous forehand and backhand advantage.

[0005] In addition, the parameters of the slope of the transition section, such as the slope length, inclination angle, and step height are often selected based on experience and do not conform to the principles of ergonomics and force generation. Utility Model Content

It should be understood that this overview is not an exhaustive overview of the present invention. It is not intended to identify key or important aspects of the present invention, nor is it intended to limit the scope of the present invention. Its purpose is simply to present certain concepts in a simplified form as a prelude to the more detailed description discussed later.

[0007] In view of this, in order to solve the above problems, the present invention proposes a table tennis racket with an asymmetric handle, which shortens the time for switching between forehand and backhand.

[0008] The utility model provides a table tennis racket with an asymmetrical handle, comprising:

[0011] The waist edge surface forms a waist curve along the extended plane of the racket face; the side edge surface forms a side curve or a side straight line along the extended plane of the racket face;

[0012] The curvature of the waist curve is greater than that of the side curve.

[0013] In one possible implementation, the waisted facet includes a plurality of facets connected in sequence, the side facets include a plurality of facets connected in sequence, and the number of facets included in the side facets is equal to the number of facets included in the waisted facets.

[0014] In one possible implementation, the waisted facets include: a first facet, a second facet, and a third facet; and the side facets include a fourth facet, a fifth facet, and a sixth facet;

[0015] The second edge face and the third edge face are symmetrically arranged; two sides of the second edge face are respectively connected to the front plane and the first edge face, and two sides of the third edge face are respectively connected to the back plane and the first edge face;

[0016] The fifth and sixth facets are symmetrically arranged; two sides of the fifth facet are connected to the front facet and the fourth facet respectively, and two sides of the sixth facet are connected to the back facet and the fourth facet respectively;

[0017] The first facet is an elliptical cylinder, and the second and third facets are elliptical cylinders or planes;

[0018] The fourth facet is an elliptical cylinder or a plane, and the fifth facet and the sixth facet are elliptical cylinder or a plane.

[0019] In one possible implementation, arc surfaces for smooth transition are provided at the connections between the first, second and third faces of the waisted face; and arc surfaces for smooth transition are provided at the connections between the fourth, fifth and sixth faces of the side face.

[0020] In one possible implementation manner, the width of the first edge face and the width of the fourth edge face are the same as the thickness of the racket face.

[0021] In one possible implementation, the angle between the second edge facet and the front plane is 100°-130°, the angle between the second edge facet and the first edge facet is 150°-170°, the angle between the third edge facet and the back plane is 100°-130°, the angle between the third edge facet and the first edge facet is 150°-170°, the angle between the fifth edge facet and the front plane is 100°-130°, the angle between the fifth edge facet and the fourth edge facet is 150°-170°, the angle between the sixth edge facet and the back plane is 100°-130°, and the angle between the sixth edge facet and the fourth edge facet is 150°-170°.

[0028] The table tennis racket with an asymmetrical handle of the present invention combines the advantages of a waisted handle and a straight handle, transforming the outer surface of the handle from the existing bilateral symmetry to an asymmetry. This not only facilitates swing speed but also forehand power generation, shortening the time required to switch between forehand and backhand, accelerating swing speed and facilitating forehand and backhand power generation, and further stabilizing the action and power generation during multiple rotations of the racket during play. Furthermore, by defining the relationship between various parameters of the surface slope of the transition section, when the thumb grasps the surface slope of the transition section, it cooperates with the index finger, middle finger, ring finger, and pinky finger to facilitate power generation.

DETAILED DESCRIPTION

[0039] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. For the sake of clarity and conciseness, not all features of the actual implementation are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the process of developing any such actual implementation in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and these constraints may vary depending on the implementation. In addition, it should be understood that although the development work may be very complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the content of this disclosure.

[0040] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, the accompanying drawings only show the device structure closely related to the solution according to the present invention, while omitting other details that are not closely related to the present invention.

[0041] like Figure 2 As shown, an embodiment of the present invention provides a table tennis racket with an asymmetric handle, comprising:

[0042] A racket face, and a racket handle connected to the racket face via a transition section;

[0043] The handle comprises a cylindrical body for holding, the outer surface of the cylindrical body comprising a front plane 1 and a back plane 2 arranged opposite to each other, as well as a waist edge surface and side edges arranged opposite to each other; arc surfaces for smooth transition are provided at the junctions of the front plane 1, the waist edge surface, the back plane 2 and the side edges;

[0044] The waist edge surface forms a waist curve along the extended plane of the racket face; the side edge surface forms a side curve or a side straight line along the extended plane of the racket face;

[0045] The curvature of the waist curve is greater than that of the side curve.

[0046] In the embodiment of the present invention, the outer surface of the handle is changed from the existing bilateral symmetry to an asymmetry. This is because the waisted handle of existing table tennis rackets causes the flesh on the lower side of the palm to press against the symmetrical side of the handle when gripping the racket in the forehand, making the grip of the handle unstable and affecting the power generation. The straight handle of existing table tennis rackets is not universally adaptable to every athlete due to the different sizes of players' hands. The table tennis racket of the embodiment of the present invention has an asymmetric handle, namely, one side is waisted (referred to as the waist facet) and the other side is straight or has a smaller waist (referred to as the side facet). This prevents the grip from being squeezed when gripping the racket in the forehand (the flesh on the lower side of the palm will not press against the side facet when gripping the racket in the forehand). Compared with the waisted handle, the table tennis racket of the embodiment of the present invention has a smaller mass, which reduces the rotational inertia of the racket handle relative to the central axis, making it easier for the racket to rotate around the central axis, which is beneficial to both the swing speed and the forehand force, thereby shortening the time for switching between forehand and backhand, speeding up the swing speed, facilitating the forehand and backhand force, and making the action and force of rotating the racket multiple times during exercise stable.

[0047] In this embodiment, the smooth curved surface of the conventional handle is replaced by the outer surface of the handle in this embodiment, which consists of a frontal plane 1, a waisted facet, a back plane 2, and a lateral facet that terminates in a continuous sequence. By flattening the front and back sides of the handle, the back plane 2 fits more snugly into the palm during a forehand grip. During a forehand power application, the handle and palm are less likely to slide relative to each other, promoting a stable and steadier movement. Similarly, the frontal plane 1 allows the middle finger, ring finger, and pinky finger to fit more snugly against the handle, preventing them from sliding relative to each other during a forehand power application, promoting a stable and steadier movement.

[0048] In the embodiment of the present invention, the connection between the front plane 1, the waist edge surface, the back plane 2 and the side edge surface is smoothly transitioned by the first arc surface 9, the second arc surface 10, the third arc surface 11 and the fourth arc surface 12 respectively. Figure 4 As shown, four arc surfaces are used to connect the planes (including the front plane 1 and the back plane 2) and the edges (including the waist edge and the side edge) end to end for a smooth transition, which can make the movements firm and stable when swinging the racket with forehand and backhand power, which is conducive to accelerating the swing speed and facilitating forehand power.

[0049] In one possible implementation, the waisted facet includes a plurality of facets connected in sequence, the side facets include a plurality of facets connected in sequence, and the number of facets included in the side facets is equal to the number of facets included in the waisted facets.

[0050] In the embodiment of the present invention, the curved surface of the conventional racket handle is replaced with multiple facets. Since the curved surface area of the conventional racket handle is larger than the flat surface area, when the surface roughness is the same, the friction work done by the curved surface is greater than that done by the flat surface during forehand-backhand switching. This friction work is unnecessary and wasted. Furthermore, due to the segmented structure of human fingers, a polyhedron composed of flat surfaces is easier to rotate. During actual hitting, the waist facets and side facets composed of multiple facets do not rub against every facet of the waist facets or side facets during forehand-backhand switching. Friction may only occur against some facets, or even only against the facets. Multiple facets with facets are easier to apply force to than the smooth curved surfaces of the prior art, making rotation easier.

[0051] In one possible implementation, Figure 4 As shown, the waisted facets include: a first facet 4, a second facet 3 and a third facet 5, and the side facets include a fourth facet 7, a fifth facet 6 and a sixth facet 8;

[0052] The second facet 3 and the third facet 5 are symmetrically arranged; the two sides of the second facet 3 are connected to the front plane 1 and the first facet 4 respectively, and the two sides of the third facet 5 are connected to the back plane 2 and the first facet 4 respectively;

[0053] The fifth facet 6 and the sixth facet 8 are symmetrically arranged; the two sides of the fifth facet 6 are respectively connected to the front plane 1 and the fourth facet 7, and the two sides of the sixth facet 8 are respectively connected to the back plane 2 and the fourth facet 7;

[0054] The first facet 4 is an elliptical cylinder, and the second facet 3 and the third facet 5 are elliptical cylinders or planes;

[0055] The fourth facet 7 is an elliptical cylinder or a plane, and the fifth facet 6 and the sixth facet 8 are elliptical cylinders or planes.

[0056] In the embodiment of the present utility model, Figure 4 As shown, the outer surface of the handle of a table tennis racket is improved from the full curved surface of the prior art to include two planes (front plane 1 and back plane 2) + six facets (first facet 4, second facet 3, third facet 5, fourth facet 7, fifth facet 6, and sixth facet 8) + four curved surfaces (first arc surface 9, second arc surface 10, third arc surface 11, and fourth arc surface 12). The structure in the embodiment of the utility model eliminates friction that does useless work while retaining friction that does useful work, which can speed up the swing speed and facilitate forehand power generation. For backhand power generation, the facet with waisted facets is still easy to switch (when switching from forehand to backhand) and apply force, which is conducive to stable movement and force generation.

[0057] In the embodiment of the present invention, the first edge surface 4 is an elliptical cylinder, that is, Figure 5 In the cross-sectional view of the handle, the projection of the first facet 4 is a straight line. Similarly, the fourth facet 7 is an elliptical cylinder or a plane. Figure 5 In the cross-sectional diagram of the handle, the projection of the fourth facet 7 is a straight line. The first facet 4 is an elliptical cylinder, and its projection onto the extended plane of the racket face is a portion of an ellipse. The fourth facet 7 is an elliptical cylinder or a plane, and its projection onto the extended plane of the racket face is a portion of an ellipse or a straight line. The portion of the ellipse can be symmetrical about the major or minor axis, or asymmetrical about the major or minor axis. The specific values of the major and minor axes of the two ellipses (with different parameters) projected on either side are determined by the degree of waisting or curvature of the table tennis racket handle.

[0058] In one possible implementation, arc surfaces for smooth transition are provided at the connections between the first edge face 4, the second edge face 3 and the third edge face 5 of the waisted edge face; arc surfaces for smooth transition are provided at the connections between the fourth edge face 7, the fifth edge face 6 and the sixth edge face 8 of the side edge face.

[0059] In one possible implementation, the width of the first facet 4 and the width of the fourth facet 7 are the same as the thickness of the racket face.

[0060] In one possible implementation, the angle between the second edge face 3 and the front plane 1 is 100°-130°, the angle between the second edge face 3 and the first edge face 4 is 150°-170°, the angle between the third edge face 5 and the back plane 2 is 100°-130°, the angle between the third edge face 5 and the first edge face 4 is 150°-170°, the angle between the fifth edge face 6 and the front plane 1 is 100°-130°, the angle between the fifth edge face 6 and the fourth edge face 7 is 150°-170°, the angle between the sixth edge face 8 and the back plane 2 is 100°-130°, and the angle between the sixth edge face 8 and the fourth edge face 7 is 150°-170°.

[0061] In one possible implementation, the width of the second facet 3 and the width of the third facet 5 are the thickness of the racket face minus 0.8 to 1.2 times the thickness of the racket face, and the width of the fifth facet 6 and the width of the sixth facet 8 are the thickness of the racket face minus 0.8 to 1.2 times the thickness of the racket face.

[0062] In one possible implementation, the center of gravity of the handle and the center of gravity of the racket face are on the same central axis.

[0063] In an embodiment of the present invention, the table tennis racket has an asymmetric handle. If materials with the same density are used, the center of gravity of the handle may not be on the central axis. In an embodiment of the present invention, a counterweight method can be used. For example, the density of the material on one side of the waist edge surface can be reduced or the hollow structure inside the handle can be changed, so that the center of gravity of the handle and the center of gravity of the racket face are on the same central axis. Here, the central axis is the central axis in two directions along the extension plane of the racket face and perpendicular to the extension plane of the racket face, that is, the symmetry axis of the racket face.

[0064] In one possible implementation, the angle between the surface slope of the transition section and the racket surface is 20°-30°.

[0065] like Figure 6 As shown, when swinging the racket forehand, a vertical line is drawn from the highest point of the surface slope of the transition section of the back plane 2 and intersects with the surface slope of the transition section of the front plane 1. If the intersection point is the midpoint of the surface slope of the transition section of the front plane 1, then the forehand force effect of this structure is the best.

[0066] Therefore, the angle θ between the surface slope of the transition section and the racket surface in the embodiment of the present invention satisfies the following expression:

[0067] in

[0068] Among them, A is the length of the surface slope of the transition section, C is the height of the step at the connection between the transition section and the racket face, and B is the thickness of the racket face. The value range of A is 12-15mm, the value range of B is 5-7mm, and the value range of C is 1.5-3mm.

[0069] The outer surface of the handle of the table tennis racket of the present invention comprises 2 planes + 6 prisms + 4 arcuate surfaces. The structure in the embodiment of the present invention has an asymmetric handle.

[0070] The table tennis racket with an asymmetrical handle of the present invention combines the advantages of a waisted handle and a straight handle, transforming the outer surface of the handle from the existing bilateral symmetry to an asymmetry. This not only facilitates swing speed but also forehand power generation, shortening the time required to switch between forehand and backhand, accelerating swing speed, and facilitating forehand and backhand power generation, but also ensures stable movement and power generation during multiple rotations of the racket during play. Furthermore, by defining the relationship between various parameters of the surface slope of the transition section, when the thumb grasps the surface slope of the transition section, it cooperates with the index finger, middle finger, ring finger, and pinky finger to facilitate power generation.
