Description

The present invention relates to a table tennis racket.

As a conventional typical table tennis racket, a shake handler racket that grips the grip portion so as to shake hands and a pen holder racket that grips the grip portion so as to surround it with the thumb and index finger are known.

As shown in FIGS. 1 and 3 of Patent Document 1, the conventional table tennis racket includes a so-called tenary racket in which one table tennis racket can be used for both a shake handler racket and a pen holder racket.

The shake handler racket has a shape as shown in FIG. 1a of Patent Document 2, and rubber is attached to both the first surface and the second surface on the opposite side of the ball striking plate, and the ball is hit on the first surface in the forehand stroke. However, in the backhand stroke, the ball is hit on the second side. Therefore, since it is possible to hit a drive that applies an upward rotation to the ball with a backhand stroke (hereinafter referred to as a backhand drive), the range of footwork is smaller than that of a pen holder racket.

As a basic method of gripping the shake handler racket, as shown in FIG. 1b of Patent Document 2, the ball striking plate is sandwiched between the thumb and the index finger, and the grip portion is gripped by the middle finger, the ring finger and the little finger. In the case of the shake handler racket, unlike the pen holder racket, the gripping portion has a large ground contact area, so that the grip is stable. Therefore, it is possible to hit a stable ball with less racket shake during a swing.

The pen holder racket has a shape as shown in FIGS. 1 and 2 of Patent Document 3, and rubber is attached only to the first surface of the ball striking plate, and FIGS. 5, 6, 7 and 7 and As shown in FIG. 8, both the forehand stroke and the backhand stroke are hit on only this one side (hereinafter referred to as a single-sided pen racket). There is also a pen holder racket (hereinafter referred to as a double-sided pen racket) in which a rubber is attached to the second surface opposite to the first surface and the grip portion of the shake handler racket that can hit the ball is shortened in the longitudinal direction.

As a basic method of gripping the pen holder racket, as shown in FIGS. 3 and 4 of Patent Document 3, the protrusion of the grip portion is surrounded by the thumb and index finger, and one of the middle finger, ring finger and little finger is used. Hold the above so that it is attached to the second surface of the ball striking plate. Compared to the shaker racket, finer racket control is possible by pressing the thumb. In the case of the pen holder racket, since the points of contact with the ball striking plate and the grip portion are the tips of the five fingers and the space between the first fingers, the contact area is small and the grip is unstable. In addition, since the double-sided pen racket does not have a protrusion surrounded by the thumb and index finger, the ground contact area is further reduced and the grip becomes more unstable. However, the degree of freedom of the thumb and index finger is high, and finer racket control is possible than the single-sided pen racket.

The single-sided pen racket has a backhand stroke as shown in FIGS. 7 and 8 of Patent Document 3, and since a backhand drive like a shake handler racket cannot be performed, the back surface is weak, and therefore, it becomes mainly a forehand stroke. Therefore, for a hit ball on the back side, a wide range of footwork such as a forehand stroke that wraps around and a jump to a hit ball that is returned to the fore side after that is required.

Since the pen holder racket has a wider wrist movement range than the shake handler racket, it is easy to rotate in service, receive and drive. In addition, by adjusting the pressure of the thumb, it is easy to finely adjust the racket angle, and it is easy to use the technique on the table tennis table that shortens the stroke.

Utility model No. 2510886 Special Table 2010-536468 Publication No. Jikkai Sho 61-106271

There is a conventional table tennis racket called a tenary racket that can be used as both a shake handler racket and a double-sided pen racket. And since the long grip 5 shown in FIG. 3 hinders the movement of the thumb, it is necessary to completely let go of the table tennis racket, and it is extremely difficult to change the grip instantly, which is not practical.

The conventional shake handler racket has a narrower wrist movable range γ as shown in FIG. 9 than the wrist movable range ε of the double-sided pen racket as shown in FIG. 11, and the service, receive and drive rotation are narrower than those of the double-sided pen racket. It is difficult to apply the racket, and it is difficult to finely adjust the racket angle by pressing the thumb, so the technique on the table tennis table is difficult.

With conventional shaker rackets, when the ball is hit in the middle of the table (near the right pocket in the case of a right-handed user), it is difficult to put out a table tennis racket in front of the body and return it, so the body You may be wondering whether to move the ball to the fore side and return the ball with the backhand stroke, or move the body to the back side and return the ball with the forehand stroke.

In the conventional shake handler racket, when the user is right-handed, when servicing, when catching the left side of the ball and applying a right lateral rotation, the grip of the table tennis racket must be changed and the shoulder and elbow must be raised to create a racket angle. In addition, a sufficient distance is required between the table tennis table and the shoulder, which is difficult for short people and children to learn.

The conventional double-sided pen racket can be backhand driven like a shake handler racket, but since rubber is attached to both sides, the racket weight becomes heavy. Grip strength and wrist strength are required to hold this with a double-sided pen racket that has a smaller gripping ground contact area, and to operate the racket control that is important in swing and bench technology.

In the conventional shake handler racket and double-sided pen racket, the grip part is configured in a straight line parallel to the ball striking plate, so there is a problem that the table tennis racket slips out completely due to the influence of centrifugal force during swing and slip due to hand sweat. There is.

The conventional table tennis racket has a ball striking plate and a grip part integrally molded, and is designed to be symmetrical up and down and left and right to support both right-handed and left-handed people (excluding the tenary racket), so due to the structure of the human hand, There was no grip that was perfectly suitable for the user. Furthermore, it is difficult to select the grip part according to the size and shape of the hand, so it is cut to make it thinner or wrapped with tape to make it thicker.

Therefore, the racket gripping force is strong even when gripping the double-sided pen racket, and it is easy to switch between gripping the shake handler racket and the double-sided pen racket. Need to be provided. That is, a table tennis racket that can utilize the advantages of both the shake handler racket and the double-sided pen racket, or overcome the drawbacks of each, is provided.

The connection to a flat plate-shaped ball striking plate 2 having a first surface 2d and a second surface 2e, and having a connecting portion 2b extending from the first surface and the second surface along an axis in the longitudinal direction. A first grip portion provided so as to sandwich the portion 2b, the first grip portion is connected to the connection portion on the first surface side, and the tip end side of the connection portion on the first surface side. A first grip portion 3a on the first surface side having a slope 3b toward the surface and a first grip portion 3d on the second surface side connected to the connection portion on the second surface side. It is a surface defined by the grip portion 3 and the end portion on the tip end side of the first grip portion, and is configured on the connection portion side of the surface C perpendicular to the longitudinal direction of the ball striking plate 2. The second grip portion 4 having an abdomen 4a and a back portion 4b continuous with the first grip portion 3d on the second surface side is provided, and the end portion 3c on the rear end side of the first grip portion on the first surface side, the connection. The end portion 2c on the rear end side of the portion and the end portion 3e on the rear end side of the first grip portion on the second surface side have a smooth continuous surface rear end portion 5 , where the tip and the rear end are combined. Provides a table tennis racket characterized in that the first surface and the second surface side are defined as the front end side and the connection portion side is defined as the rear end side in the longitudinal direction . The racket portion 23 is composed of the ball striking plate 2 and the first grip portion 3.

The second grip portion 4 has the abdomen 4a in contact with one or more of the palm or middle finger, ring finger and little finger on the tip end side of the first grip portion , and the rear end side of the first grip portion. The back portion 4b having an arc shape may be provided.

The back portion 4b of the second grip portion 4 may have an angled surface with respect to the ball striking plate 2. The "angled surface" as used in the present application means that the surface of the back portion 4b has an angle with respect to the surface of the ball striking plate 2.

The back portion 4b of the second grip portion 4 may have a surface perpendicular to the hitting plate 2.

The second grip portion 4 may have an angle with respect to a plane perpendicular to the longitudinal axis of the ball striking plate 2.

The second grip portion 4 may be detachably connected to the first grip portion 3d on the second surface side.

In the table tennis racket of the present invention, the shake handler racket and the double-sided pen racket can be gripped instantly with one hand by allowing the thumb to move smoothly due to the effect of the smooth continuous surface of the slope 3b and the rear end portion 5. It will be possible to change. This makes it possible to perform the conventional technique of striking a shake handler racket and a double-sided pen racket with one table tennis racket during a rally. In addition, it is possible to hit with a double-sided pen racket that has the advantages of wide wrist movement range and racket control during service and receive, and with a shake handler racket that has the advantages of both hand strokes during rallying. Furthermore, even with the same stroke, you can hit different quality balls by changing the grip, and the range of tactics will be wider, such as toying with the opponent.

As shown in FIG. 9, the wrist movable range γ of the conventional shake handler racket is increased to the wrist movable range δ in the gripping method of the shake handler racket in the table tennis racket of the present invention as shown in FIG. This allows more rotation of the ball during service, receive and drive.

Furthermore, even in the table tennis middle processing, which is a weak point of the conventional shake handler racket, when trying to return the ball in front of the body without moving the body, as shown in FIG. Although it faces upward and it is difficult to obtain a return angle, in the table tennis racket of the present invention, as shown in FIG. 12 (b), the ball striking surface is slanted with respect to the table tennis table 11 in the way of gripping the shake handler racket. Since it is easy to set the return angle, you can return the ball without moving your body, so you will not be confused about whether to return the ball with the forehand stroke or the backhand stroke.

Further, in the conventional shake handler racket, as shown in FIG. 12 (a), the ball striking surface faces upward with respect to the table tennis table 11, and when the user is right-handed, the left side of the ball is caught at the time of service. When applying clockwise rotation, it is necessary to change the grip and raise the shoulder and elbow to the angle β as shown in FIG. 12 (b). However, in the table tennis racket of the present invention, the grip of the shake handler racket is different. As shown in FIG. 12B, since the angle β is already formed, even a short person or a child can easily learn the service. In addition, if you change the grip and raise your shoulders and elbows as in the past, the angle range will be wider and the types of services will increase.

Further, in the conventional shake handler racket, the forehand stroke is only on the first surface 2d and the backhand stroke is only on the second surface 2e, but in the table tennis racket of the present invention, the forehand stroke is gripped by the shake handler racket. Also, the backhand stroke can be hit on the first surface 2d and the second surface 2e. Furthermore, if the user is right-handed, a new method of hitting the ball on the table tennis table with a forehand stroke by catching the right side of the ball on the second surface 2e and turning it counterclockwise becomes possible.

Further, in the table tennis racket of the present invention, in the gripping method of the shake handler racket, by changing the angle surface of the abdomen 4a or the back 4b of the second grip portion 4, or both, the ball striking plate is centered on the lateral direction of the table tennis racket. Since the angle surface of is changed, it is possible to provide a table tennis racket according to the user's preference.

The conventional shake handler racket has a method called Chiquita. To explain in detail, if the user is right-handed, use the backhand stroke against the ball that is put out shortly on the table, raise the elbow, put the elbow forward, make the elbow about 90 degrees, and fold the wrist. It is a method of hitting the ball by simultaneously performing and preparing six actions of turning the forearm downward and twisting the forearm counterclockwise, catching the left side of the ball when stroking clockwise, and turning it clockwise to return the ball. In the table tennis racket of the present invention, the shake handler racket can be gripped only by three actions of pushing the elbow forward, folding the wrist, and folding the elbow, so that the same striking method can be performed quickly and easily. .. In addition, since it is not necessary to raise the elbow, it is possible to hit even a short person.

In the table tennis racket of the present invention, in the method of gripping the pen holder racket, a double-sided pen racket form that enables backhand drive by attaching rubber to the second surface 2e is adopted. As a result, the weight of the racket increases, the grip becomes unstable, and the racket control becomes difficult. It is solved by making it possible to grasp it by wrapping it with the finger ball. This enables stable gripping without grip strength or wrist strength, makes it difficult to feel the weight, and improves the holding power, swing speed, and racket control of the table tennis racket.

Further, with the conventional pen holder racket, it is difficult to move the thumb and the index finger at the same time, but in the gripping method of the double-sided pen racket of the present invention, the thumb and the index finger are free because the gripping of the second grip portion 4 is stable. By becoming, it becomes possible to diversify the gripping method, finely adjust the gripping method at the time of service, receive and rally, and further improve the racket control.

The conventional shake handler racket and the grip portion of the double-sided pen racket have a problem that the table tennis racket slips out completely, but in the table tennis racket of the present invention, as shown in FIG. 13, the second grip portion 4 is gripped. Therefore, in the pulling direction D of the table tennis racket, one or more of the middle finger, the medicinal finger, and the small finger are hung on the gripping method of the double-sided pen racket, and the palm is hung on the gripping method of the shake handler racket, so that this problem is improved. As a result, the swing speed can be increased, so that a ball with higher power and higher rotation can be hit.

In the table tennis racket of the present invention according to claim 5, as shown in FIG. 8, the second grip portion 4 has an angle θ with respect to a plane perpendicular to the axis in the lateral direction of the ball striking plate 2. Regarding how to grip the double-sided pen racket, if the user is right-handed, if it is biased to the right (state in Fig. 8), it is easy to make a ball striking face that makes it easy to make a backhand stroke, and if it is biased to the left, it makes a forehand stroke. It becomes easy to make an easy hitting surface. In the way of gripping the shake handler, if the ball is biased to the right, the tip of the racket faces upward during the forehand stroke and the backhand stroke, so that more rotation can be applied when hitting the ball with a downward rotation. Furthermore, when returning the ball by rotating upward, it becomes easier to return the ball in the straight direction. When the ball is biased to the left, the tip of the racket faces downward during the forehand stroke and the backhand stroke, so that more rotation can be applied when the ball is hit with an upward rotation. This makes it possible to provide a table tennis racket that is more suited to the user's preference.

Conventional table tennis rackets do not have a grip that is perfectly suitable for the user, and there are few options. However, in the table tennis racket of the present invention according to claim 6, if the same attachment / detachment mechanism is mounted on the other racket portions 23 by making the second grip portion 4 removable, right-handed, left-handed, and hand-handed. It is possible to provide a wide variety of second grip portions 4 having different sizes, favorite shapes, thicknesses and lengths of grip portions. Further, the material of the second grip portion 4 is changed to make it heavier, the inside is made hollow to make it lighter, and the weight and the position of the center of gravity can be easily adjusted together with the side tape, so that more users are more suitable. , Or you can select the table tennis racket according to the situation.

From the above, even if there is a table tennis racket desired by the user, the problem that it cannot be used when the grip portion does not fit is solved.

Conventionally, when changing the table tennis racket, if you try to use a table tennis racket other than the exact same series, there is a slight difference in thickness and shape due to the difference in manufacturer and series even with the same type of grip, but it is billed. In the table tennis racket of the present invention according to the item 6, if only the racket portion 23 is replaced and the previous second grip portion 4 is used as it is, the new table tennis racket can be immediately adapted to the new table tennis racket with the same gripping feeling as before. .. Further, by replacing the familiar rubber and racket portion 23 with the second grip portion 4 having a different shape, it becomes easy to find a grip portion that is more suitable for the user while maintaining the same shot feeling. This makes it possible to try out various racket parts 23, second grip parts 4 and rubbers of other users at school club activities, local club practice and game venues, which is suitable for users. The racket portion 23, the second grip portion 4, and the rubber are also easy to find, which is effective not only for improving the skill of the user but also as a communication tool.

In the table tennis racket of the present invention according to claim 6, the racket portion 23 with the second grip portion 4 removed is shorter in the longitudinal direction than the conventional table tennis racket, so that it is easy to store and carry.

In terms of manufacturing and sales, in the conventional table tennis racket manufacturing, the ball striking plate and the grip portion are integrated, so even the table tennis racket of the same series must be manufactured separately for the grip portion. For example, there are four main grips: flare, straight, anatomical and double-sided pens. Four table tennis rackets with different grips must be manufactured, and if one of them is sold, three will be in stock. In the table tennis racket of the present invention according to claim 6, if one racket portion 23 is manufactured and four types of low-cost second grip portions 4 are manufactured, the racket portion 23 is out of stock and three types are manufactured. The second grip portion 4 remains. However, this second grip portion 4 can also be used for the racket portion 23 of another series. From this, there are merits in improving the efficiency of inventory management and reducing manufacturing costs. Further, since the number of rackets 23 having a large proportion of timber can be reduced, there are merits in timber resource management and transportation cost reduction.
