Description

Technical Field

[0001] The utility model relates to a table tennis racket, in particular to a high-power, fast-arc, straight-grip table tennis racket. Background Art

[0002] Technical goal: After the big ball was put into use, the penhold racket's performance against the horizontal racket has been getting worse and worse due to the double attack of power problems and the old problem of backhand physiological limitations. However, the penhold racket itself has very special characteristics that cannot be replaced by the horizontal racket, such as flexibility on the table, quick start near the table, comfortable wrist holding and many changes. The penhold racket also represents my country's traditional technical playing style. There are many fans of the penhold racket technology among the people, and the market size is very large. It would be a great wish of golfers to increase the power of pulling on both sides and the problem of backhand limitations while retaining the advantages of the penhold racket in flexibility, changeability and speed.

[0003] Existing technology: With this desire, there are also existing technologies that have been developed one after another, and there is also CN201120566805.4, which adds an index finger force structure close to the Chinese straight-grip racket. The index finger bump is added to the index finger auxiliary force structure to achieve the purpose of improving the straight-grip power. However, the problems of the existing technology are also very prominent.

[0004] Problems in using existing technologies:

[0005] First, the racket shape is limited in rotation: after adding the index finger bump, the thumb is always blocked by the grip when adjusting and rotating the racket and is not flexible, which is easy to be limited and adjusted in place, resulting in mistakes, which makes the existing technology unable to enter the actual game of high water level;

[0006] Second, the grip is uncomfortable and the feel is not good: after adding the index finger bump, the grip becomes uncomfortable, and the thumb is always touched by the grip, which not only affects the feel, but also affects the performance of the technique;

[0007] The negative effects of these problems far outweigh the effect of the increased strength brought by the index finger bump, and instead reduce the effect of the improvement.

[0008] The difficulty points in solving the above problems are:

[0009] First, while adding the index finger bump to assist in generating force, flexibility must not be restricted. Otherwise, the core competitiveness of the pen-hold racket - flexibility - will be lost. This is a difficult balance.

[0010] Second, when the index finger bump is added to the auxiliary force structure, what changes have taken place in the entire grip, especially in the finger control of various technical movements. Only by analyzing the subtle changes can we find the root cause of the problem.

[0011] Third, changes in the racket structure often have a ripple effect on the entire structure. A large number of failed improvement cases are due to failure to consider the negative effects of the improvement, which often results in a gain of one point but a loss of another.

[0012] The significance of solving the above problems is:

[0013] If these problems can be solved, especially the flexibility problem, the pen-hold racket will achieve successful structural improvements in terms of improving power. That is, the solution of adding an index finger bump to assist the structure of the index finger can be put into practical use, because the increase in power caused by the index finger bump is obvious. This will give the pen-hold racket a basic condition to compete with the horizontal racket. After making up for the defects of the pen-hold racket, the characteristics of the pen-hold racket can be brought into play, which will allow rackets with an index finger force-assisting structure to enter high-level actual combat and alleviate the marginalization of the pen-hold racket in the professional field. Among competitive equipment, folk equipment follows the development of professional equipment, and can also rekindle the enthusiasm of the public, especially young people, for pen-hold rackets.

[0014] Maintain the rich charm of table tennis and let the table tennis world maintain its rich colors. We all know that in the badminton and tennis worlds, the rackets and equipment are all of a single shape, only table tennis rackets have a variety of styles, and the rich variety of equipment is also one of the charms of sports promotion.

[0015] Continuing the straight-grip feature, the straight-grip feature can be retained in table tennis equipment. Since the rise of Chinese table tennis, the straight-grip has been a feature. Although it is less used by professional athletes in our country now, the straight-grip is deeply marked by the East. I can't imagine what else in table tennis equipment will have our traditional straight-grip feature after this feature disappears. Utility Model Content

[0016] The utility model aims to solve the technical problem of the prior art and provide a high-power, fast-arc, straight-grip table tennis racket which increases power and can be flexibly adjusted.

[0017] The utility model adopts the following technical solution to solve the above technical problems: a high-power, fast-arc, straight-grip table tennis racket, comprising a hitting plate and a grip, wherein the grip comprises a front handle block, a rear handle block and an upper portion of the hitting plate, and is characterized in that a convex block is provided on the index finger side of the front handle block, a thumb chamfer is provided on the thumb side of the front handle block, and the thumb chamfer is inclined toward the center direction of the grip. The effect of this structure solves two major problems of the prior art, namely, limited racket angle rotation and uncomfortable holding; the thumb bevel cuts off a corner of the grip, so that the thumb has room to move, which solves the problem of thumb being blocked when rotating the racket, and also solves the problem of limited racket shape rotation. In addition, the thumb directly presses on the flat shoulder of the hitting plate, and the problem of pressing the grip and causing uncomfortable hand feeling is solved. Why does the increase of protrusions in the prior art cause the thumb to press on the grip corner? After long-term research and analysis, it is found that the increase of protrusions widens the holding width between the index finger and the thumb. At this time, the thumb is naturally pulled closer to the middle side of the grip, which naturally presses on the grip corner. The structure of the utility model first frees up enough space for the thumb to move through the thumb bevel. The utility model also has some unexpected effects during use. First, the utility model positions the thumb. The structure of the thumb bevel allows the thumb to easily fit on the thumb bevel without losing flexibility, and then quickly return to the original position after adjusting the grip. This positioning structure The utility model discloses a kind of structure, and it is indispensable in actual combat; secondly, it makes the top force given by the thumb to the oblique surface of the thumb increase the force; thirdly, the structure of the utility model makes the holding realize the side grip method which is very suitable for the straight racket two-sided loop playing method. This side grip method means that the racket face can be rotated at a large angle when holding, and the inclination angle of the backhand racket face is adjusted in a larger range, which increases the inclination angle range of the backhand racket face, that is, it solves the problem that the straight racket horizontal hitting is always a little awkward and not as free as the horizontal racket. In fact, it is an increase in the degree of freedom of the wrist, which is not only conducive to the backhand pressing down the racket shape to draw loops, but also easy to press down the racket shape to draw forward loops for the forehand. In addition, this holding method is more stable and powerful, close to the horizontal racket; in summary, the utility model solves the problem of the inflexibility of the thumb existing in the prior art, and also eliminates the negative effect of the inability to locate the thumb activity that may be caused after the problem is solved, and produces certain unexpected effects. The innovation of table tennis rackets has never been a simple creativity, and it must be based on theoretical cognitive analysis based on the understanding of technology, so as to improve the racket structure without affecting the complex technical system.

[0018] Furthermore, the thumb bevel is a plane. The effect of this structure is that the structure is simple, the thumb pressing pressure feels clear and comfortable, the thumb applies a top force without slipping, and the most important thing is that the thumb touches the handle of the racket when holding it, which is also a problem in the prior art. The thumb pressing point of the traditional pen-hold racket is a corner of the handle, which is abrupt and irregular, uncomfortable to press, and unable to apply top force. The prior art has a curved surface, and the curved surface pressing feeling is not clear, especially the sense of direction is very poor. When applying force, the force application will also be unstable due to the curved surface problem. In addition, this structure is more convenient in production.

[0019] Furthermore, the thickness of the handle on the thumb side of the cross section of the rear handle block is greater than the thickness of the handle on the index finger side. The effect of this structure is that, in combination with the protruding block, it is conducive to the lateral grip when pulling the loop. When holding it sideways, the rear handle block is thicker on the thumb side, which can better fit the concave part of the base of the thumb, and the thinner part on the index finger side of the rear handle block is pressed against the joint at the root of the index finger, achieving a stable fit without increasing the flexibility barrier. This point, combined with the protruding block, achieves the effect of high fit and unhindered flexibility in holding, which is particularly comfortable to hold and conforms to the curve of the hand shape.

[0020] Furthermore, the intersection line between the thumb bevel surface and the hitting board is the thumb bevel line, and the thumb bevel line is higher on the thumb side than on the index finger side. The effect of this structure is to give the thumb more room for movement, which is suitable for a wider front handle block.

[0021] Furthermore, at least a portion of the thumb bevel line is located at the edge of the thumb near the base of the thumb when holding the racket. The effect of this structure is that the thumb touching the thumb bevel surface plays a role in further accurately locating the thumb position, and it is also more convenient for the thumb to apply a top force, such as the top force when pulling an arc loop.

[0022] Furthermore, the angle between the thumb bevel and the hitting board is between 20 and 60 degrees. The effect of this structure is that within this angle range, the thumb can give the thumb bevel enough force to assist in pulling the ball, while also taking into account the flexible movement space of the thumb. If the angle is less than 20 degrees, the force is insufficient, and if the angle is greater than 60 degrees, the flexible movement space of the thumb is limited.

[0023] Furthermore, the thumb oblique line is a straight line, and the angle between the thumb oblique line and the racket center axis is 5 to 55 degrees. The effect of this structure is that the thumb can fit well within this angle range without affecting the flexibility and touch of the thumb.

[0024] Furthermore, the protrusion includes a protrusion lower slope, and the protrusion lower slope coincides with the thumb bevel. The effect of this structure is that it is suitable for deep grip, because the thumb goes deeper into the batting board due to deep grip, and the thumb bevel and the protrusion lower slope are in the same plane without hindering the movement of the thumb.

[0025] Furthermore, the projection includes an outer side surface of the projection, and the angle between the outer side surface of the projection and the hitting plate is 55 degrees to 85 degrees. The effect of this structure is that the index finger has flexible space and sufficient hook resistance.

[0026] Furthermore, a thumb side section is provided above the thumb bevel section. The structural effect is that the bevel section is combined with the thumb side section to provide a larger space for movement.

[0027] Furthermore, the side projection and front projection of the protrusion are trapezoidal. The effect of this structure is that the index finger has enough space to move when it hooks the lower inclined surface and the outer side surface of the protrusion, which makes the entire index finger hooking the protrusion flexible and free, and at the same time, the pressing force is stable and non-slip, and the sense of direction of holding is good.

[0028] Comparing the traditional straight-shot and existing technology experimental results:

[0029] Use of technical effects Traditional pen-hold Prior art The utility model Forehand power: Medium strength Too strong Powerful Thumb flexibility: flexible Inflexible Very flexible Backhand power: Small power Strength Powerful Backhand Comfort: Discomfort Discomfort Comfort Push-off comfort: Comfort Discomfort Comfort Usage habits: Habit Unaccustomed Habit Forehand and backhand press: Discomfort Discomfort Comfort

[0030] The utility model fully inherits the characteristics of the traditional pen-hold racket, solves the problems of uncomfortable holding and inflexible racket rotation caused by adding an auxiliary control structure of the index finger, and does not cause new negative effects.

[0031] The positive industrial effects of this utility model are:

[0032] The utility model basically solves the core problems of the current traditional pen-hold racket, and maintains the original technical features and usage habits. The utility model enables the technology of traditional pen-hold rackets in my country to be maintained and developed, attracting more young people to use pen-hold rackets, which is conducive to the promotion of the national ball culture. The utility model has a simple structure and low production and processing costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0062] The terms "front", "back", "up", "down", "left" and "right" in the present invention are relative to the front view of the racket ( Figure 1 ), the direction close to the observer is "front" (i.e. the front side of the racket), the direction away from the observer is "back" (the back side of the racket), and "lateral" refers to the left and right directions. The utility model takes the right-handed racket as an example, the left side of the racket is the index finger holding position, and the right side is the thumb holding position.

[0063] Embodiment 1

[0064] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the lower inclined surface 11 of the front handle block 1 overlaps with the lower inclined surface 41 of the protrusion, and a thumb bevel surface 15 is provided on the right side. The thumb bevel surface 15 and the hitting plate 3 intersect the thumb bevel line 17. The protrusion 4 is composed of the lower inclined surface 41 of the protrusion, the outer side surface 42 of the protrusion and the edge 43. The outer side surface 42 of the protrusion is 70 degrees with the hitting plate, and the lower inclined surface 41 of the protrusion is 50 degrees with the hitting plate, so that the index finger has a large space for movement and the finger becomes flexible. The protrusion 4 extends laterally to the side of the index finger. This structure increases the torque of the index finger's hooking and makes the hooking force stronger. Figure 6As shown, the intersection of the thumb chamfer 15 and the hitting plate 3 is the thumb chamfer line 17, and the thumb side of the thumb chamfer line 17 is inclined toward the upper side of the grip and is located at the edge 19 of the thumb near the index finger, which just positions the thumb for gripping, so that the thumb can be accurately reset when the grip is constantly changed and adjusted; the angle between the thumb chamfer 15 and the hitting plate 3 is 40 degrees, and the angle between the thumb chamfer 17 and the central axis 31 of the racket is 30 degrees, so that the index thumb has both support and sufficient space for movement when gripping; the upper end of the thumb chamfer 15 ends at the end 16 of the thumb chamfer, and the upper end of the front handle block 1 is thinner than the lower end 12 of the front handle block, which can not only increase the height of the lower inclined surface 11 of the entire front handle block and increase the grip area of ​​the index finger, but also reduce the weight; as shown in FIG. Figure 2 As shown, the cross section of the rear handle block 2 is an oblate structure, and the thumb side is thicker than the index finger side, which makes the rear handle block 2 more closely fit the shape of the tiger's mouth when holding, because the tiger's mouth shape itself is deeper near the thumb and shallower near the index finger, especially when the tiger's mouth rotates toward the thumb side in the arc holding posture, this is more obvious. The holding of this embodiment is: Figure 6 As shown in the figure, the right-handed racket arc attack holding posture of this embodiment is used, the first joint of the index finger is hooked on the lower inclined surface 41 of the protrusion, the base of the thumb is pressed on the rear handle block 2, the first joint and a part of the second joint of the thumb are pressed on the shoulder of the hitting plate 3, the edge 19 of the thumb near the base of the thumb is pressed on the beveled surface 15 of the thumb, and the first joints of the middle finger and the ring finger are pressed on the back of the hitting plate 3; Figure 7 As shown, this is the push-block holding posture of the racket held by the right hand in this embodiment, the first joint of the index finger hooks the lower inclined surface 41 of the convex block, the base of the thumb is separated from the rear handle block 2, and the first joint of the thumb presses on the outer side surface 13 of the thumb of the front handle block; the use of this embodiment is: when exerting force on the forehand and backhand loop balls, the first joint of the index finger hooks the lower inclined surface 41 of the convex block to exert force, so that the index finger has enough resistance to exert force at the last moment of exerting force to achieve a whipping effect, because the racket will not fall out of the hand due to the hook of the index finger, the thumb, middle finger and ring finger can be relaxed when holding, and the wrist is more relaxed at this time, and the whipping effect is better, the thumb presses the right shoulder, and the left side of the thumb sticks to the beveled surface 15 of the thumb, and when the racket is turned left and right to adjust the racket shape, the thumb presses the right shoulder, which has enough space for flexible adjustment, good hand feel, and can be relied on On the thumb bevel surface 15, when exerting force in forehand and backhand loops, the thumb can press against the thumb bevel surface 15 to increase the force; when performing forehand and backhand quick attacks, the hooking of the index finger can also bring a greater improvement and stability to the force, especially for backhand quick attacks, using the back of the hitting board 3 to hit the ball. At this time, the index finger hooking force is more critical, and the thumb is attached to the thumb bevel surface 15, and the quick attack is more stable; when pushing and blocking, the outer side surface 42 of the protrusion and the lower bevel surface 41 of the protrusion combine with the hitting board 3 to provide a full support for the pushing and blocking grip, and this support does not affect the flexibility of the fingers, and is conducive to adding force to push and block and rebound. The thumb presses on the outer side surface 13 of the thumb of the front handle block, which provides great support for the thumb pressing. Compared with the Chinese pen-hold racket, the pushing and blocking force is increased, and the flexibility will not be lost.

[0065] Embodiment 2

[0066] See also Figure 8 , Fig. 9 , Fig.10 , Fig.11 Fig.12 , Fig.13 and Fig.14 As shown, the difference from the first embodiment is that the area of ​​the thumb bevel 15 is larger, which makes the area of ​​the outer side surface 13 of the thumb of the front handle block very small, and the thumb pressing auxiliary function when pushing and blocking is lost. However, the advantage of this structure is that the thumb has a greater force against the thumb bevel 15 when the two-sided arc loop is exerted, which is greater than the arc loop force of the first embodiment, and is suitable for the technical style of play that emphasizes the two-sided arc loop and abandons pushing and blocking. In addition, the convex block 4 extends laterally longer, which greatly increases the power of the index finger to hook and exert force, and can hit a more powerful arc loop ball. The rear side of the convex block 4 is provided with a convex block 48 extending above the hitting plate 3, which makes the third joint of the index finger when holding the racket have a greater braking effect, which is conducive to the exertion of greater force; the grip of this embodiment is: as Fig.14 As shown, the holding posture for loop technique is basically the same as that in the first embodiment. This embodiment is suitable for loop technique but not for push and block. The use of this embodiment is that the power of forehand and backhand loop balls and forehand and backhand quick attack are similar to those in the first embodiment, except that the power of loop is greater.

[0067] Embodiment 3

[0068] See also Fig.15 , Fig.16 , Fig.17 , Fig.18 , Fig.19 and Fig. 20 As shown, the difference from the first embodiment is that the lower inclined surface 11 of the front handle block, the lower inclined surface 41 of the protrusion and the beveled surface 15 of the thumb are in the same plane, the outer side surface 42 of the protrusion is perpendicular to the hitting plate 3, and the protrusion 4 does not extend laterally, which makes the handle small and flexible. The gripping force of this embodiment is slightly smaller than that of the first and second embodiments, and it is relatively small and flexible. This embodiment is suitable for the techniques of changing and clever playing, such as Fig. 20 As shown, this embodiment is suitable for push-blocking technology. The grip of this embodiment is: Fig.19 As shown, the holding posture for arc loop attack in this embodiment is consistent with that in the first embodiment; Fig. 20 As shown, this is the pushing and blocking holding posture of this embodiment, and the holding posture is consistent with that of embodiment one; the use of this embodiment is: the difference between the use of this embodiment and embodiment one is that, since the protrusion 4 is closer to the central axis 31 of the racket, it is more flexible when rotating and changing, and the relative force is smaller, which is more suitable for the fast and flexible playing style of fast arc and pushing and blocking on both sides of the table.

[0069] Embodiment 4

[0070] See also Fig.21 , Fig. 22 and Fig.23 As shown, the difference from the third embodiment is that a thumb side section 18 is provided at the thumb of the front handle block 1, which makes the thumb more suitable for supporting the side of the front handle block 1, obtaining greater lateral force, increasing the activity area of ​​the thumb position of the front handle block, and the thumb activity space is larger, and the thumb is more flexible. Since the protrusion 4 is closer to the central axis 31 of the racket, it is more flexible when rotating. This embodiment is suitable for flexible and changeable two-sided arc loop playing methods. The arc loop grip of this embodiment is the same as that of the third embodiment: the arc loop attack grip posture is consistent with that of the third embodiment; the use of this embodiment is the same as that of the third embodiment, except that the rotation of the racket is more flexible and is not suitable for pushing.

[0071] Embodiment 5

[0072] See also Fig.24 , Fig.25 , Fig.26 and Fig. 27 As shown, the difference from the first embodiment is that the thumb bevel surface 15 does not intersect with the hitting plate 3. This structure allows the thumb to more forcefully press against the thumb bevel surface 15. Although the thumb has a small space for movement, it is more suitable for offensive power play. This embodiment is used in the same way as the first embodiment and is suitable for pushing and blocking.
