Fig. 1 is a perspective view showing a table tennis bat device 100 for practice of swinging of the present invention, fig. 2a is an exploded perspective view showing the table tennis bat device 100 for practice of swinging of the present invention, and fig. 2b is an exemplary plan view in which a weight 14 is provided in a weight adjustment section 20 and a bat handle section 10.

A table tennis bat device 100 for practicing swinging of a bat of the present invention includes a handle portion 10 and a weight adjusting portion 20.

The paddle portion 10 is configured to be supported by a hand of a user. For example, the handle portion 10 may be formed of a horizontal grip that is held by a user such as a hand or a vertical grip that is held by a user such as a pen. However, the grip portion 10 is not necessarily limited to the lateral grip or the straight grip, and may be formed in a variety of ways according to the grip method required by the user. Fig. 1 and 2a show an example of a grip portion 10 of a lateral holding type.

The weight adjusting unit 20 is connected to one side of the handle unit 10, and is configured to be capable of adjusting the weight.

According to fig. 2a, the handle portion 10 may be made of two

parts

13a and 13 b. In this case, each handle portion 10 is formed to be connected to a first member 21 and a second member 26 of a weight adjusting portion 20, which will be described later.

Referring to fig. 1, the handle portion 10 is detachably coupled to the weight adjustment portion 20.

A handle portion 10, which may include, for example, a handle 11 to be held by a user; a connecting part 12 connected with the handle 11 and connected with the weight adjusting part 20. The joint portion 12 of the handle portion 10 is preferably made of a material having sufficient rigidity to prevent breakage such as bending or breaking.

In general, a practice racket for swing is used to practice swing and is not used in an actual table tennis game, and therefore, a handle of the practice racket for swing is formed of a material different from that of an actual table tennis racket and in a slightly different shape, and it is preferable that the handle 11 of the present invention is made of the same material as that of an actual racket.

The coupling portion 12 of the handle portion 10 may be coupled to one side of the weight adjusting portion 20 by a screw or may be coupled by glue for table tennis articles.

The handle part 10 is detachably coupled to the weight adjustment part 20 through the coupling part 12, so that a handle of a type desired by a user is connected to the weight adjustment part 20, and the user can further improve the swing practice effect by using the same handle as his or her own racket used in an actual game. The racket handle can be a straight racket handle, namely an ST racket handle or an FL racket handle with a curved surface shape.

The weight adjustment unit 20 includes an accommodating unit 22 that can accommodate the weight 14, and covers one side of the accommodating unit 22 to prevent the weight 14 accommodated in the accommodating unit 22 from being detached. The storage unit 22 may be provided in plural, and the user may adjust the weight by installing the weight 14 in some or all of the storage units 22 among the plurality of storage units 22 according to his or her swing ability.

In the present invention, the swing ability may include at least one of a swing speed, a swing strength, a swing accuracy, and a handle accuracy.

While a typical table tennis bat includes a striking plate to which rubber for striking a table tennis ball is attached to the handle portion 10, the table tennis bat device 100 for practice of swing of the present invention is not a bat for actually striking a table tennis ball, but a device for practice of swing only in order to improve the swing ability of a user, and therefore, a weight adjustment portion 20 for practice of swing by adjusting the weight is connected to the handle portion 10.

The accommodating portion 22 may be formed of a plurality. The plurality of accommodating portions 22 may be formed such that the plurality of weights 14 are provided on the weight adjustment portion 20 from the side connected to the handle portion 10 to the other side opposite to the handle portion 10.

The receiving portion 22 may include: a first accommodating portion 22a for accommodating a relatively large weight, i.e., the first weight 14 a; and a second accommodating portion 22b for accommodating a relatively small weight, i.e., the second weight 14 b. For example, as shown in fig. 2a and 2b, a first receiving portion 22a may be formed in the middle portion of the weight adjusting portion 20, and a second receiving portion 22b may be formed in the head portion (left side in the drawing).

The user sets a required number of weights 14 in the plurality of accommodating portions 22 according to his swing ability. By providing a required number of weights 14 in the plurality of accommodating portions 22, the weight of the weight adjustment portion 20 can be adjusted.

Fig. 2a and 2b show an example in which 2 first weights 14a are provided in the

first housing portion

22a and 2 second weights 14b are provided in the second housing portion 22b, but the present invention is not limited to this configuration, and more weights may be provided in the first housing portion 22a and the second housing portion 22 b.

The weight adjustment part 20 may include a first member 21 and a second member 26. The first member 21 is connected to one side of the handle 10, and is formed with an accommodating portion 22 including a first accommodating portion 22a and a second accommodating portion 22 b. Fig. 2a shows an example in which the first housing portion 22a and the second housing portion 22b are formed in the first member. The second member 26 is detachably provided to the first member 21, and can cover one side of the accommodating portion 22 to prevent the weight 14 from being detached. As an example, fig. 2a shows an example of the second member 26 that can cover the upper side of the housing portion 22. A portion of the second member 26 covering the receiving portion 22 may be protrusively formed. It will be appreciated that the second member 26 acts as a cover over the first member 21 to prevent the weight 14 from being disengaged.

Fig. 2a shows a first part 21 connected to the handle 10; and a second member 26 detachably provided to the first member 21 to cover the accommodating portion 22 of the first member 21, thereby preventing the disengagement of the weight 14.

Fig. 2a and 2b show an example in which 2 first weights 14a are provided in the

As described above, the first receiving portion 22a may be formed at the central portion of the first member 21, and the second receiving portion 22b may be formed at the head portion of the first member 21. As an example, the first weights 14a may each be 70g, and the second weights 14b may each be 30 g.

In this way, by disposing the relatively heavy first weight 14a in the center portion of the racket, the weight of the racket is uniformly concentrated in the center portion of the racket, and disposing the relatively light second weight 14b in the head portion of the racket to prevent the weight from being concentrated in the head portion of the racket, so that the table tennis racket device 100 can be prevented from being separated from the hand of the user when performing a swing exercise.

The weight 14 is accommodated in the accommodating portion 22, and a weight fixing member 23 for supporting and fixing the weight 14 may be provided to prevent the weight 14 from moving.

The weight 14 is accommodated in the accommodating portion 22 in a state of being disposed on the weight fixing member 23, so that the weight can be stably and conveniently put in the accommodating portion 22 or the weight 14 can be taken out from the accommodating portion 22, and the movement of the weight 14 can be minimized at the time of performing the swing exercise, thereby preventing the excessive noise or the vibration transmitted to the hand.

Fig. 2a and 2b show an example in which the first weight 14a and the second weight 14b are accommodated in the first accommodating portion 22a and the second accommodating portion 22b in a state in which they are provided in the shaft fixing member 23, respectively. The shaft fixing member 23 may be made of a rubber material.

On the other hand, as shown in fig. 2a and 2b, an additional receiving portion 17a is formed in the handle portion 10, and a third weight 17b is provided in the additional receiving portion 17a, thereby uniformly distributing the weight to the entire table tennis bat device 100.

Fig. 3a is a plan view showing the inner side surface of the second member 26 of the weight adjustment unit 20, fig. 3b is a conceptual view showing that the second member 26 is slidably coupled to the first member 21, and fig. 3c is a cross-sectional view showing the first member 21 and the second member 26 taken along the line a-a' in fig. 3 b.

According to fig. 3a, the second member 26 is formed with a locking portion 28, and the locking portion 28 is formed in a curved shape and can be locked to the receiving groove 24 of the first member 21.

According to fig. 3c, the detent 28 may comprise a protrusion 28a protruding on one side of the second part 26; and a locking end 28b connected to the protruding portion 28a and extending in a direction intersecting the protruding portion 28a (see fig. 3 c). Further, although not shown, the housing groove 24 may include a projection (not shown) extending in parallel with the locking end 28 b; and an inclined portion (not shown) for sliding the locking portion 28.

Fig. 3b shows a structure in which the locking portion 28 of the second member 26 is slidably engaged with the receiving groove 24 of the first member 21, and the first member 21 and the second member 26 are slidably engaged with each other in the arrow direction.

Also, as shown in FIG. 4, a control module 30 may be provided at the paddle portion 10. The control module 30 may include a USB terminal 31, a switch 33, a sensing part 35, and a communication part 37.

The switch 33 is disposed on a substrate of the control module 30, and provides a switch signal to the control module 30 to turn on or off the control module 30.

The sensor unit 35 may be configured to measure a trajectory angular velocity and a swing acceleration of the swing motion of the user. Therefore, the sensor unit 35 can set the relative coordinates of the x, y, and z axes by itself, and can generate and transmit information values for the position signals according to the swing direction and trajectory of the user. The sensing part 35 may be disposed on a substrate of the control module 30. An example of the sensor 35 may be a gyro sensor.

The communication unit 37 may communicate with a smart phone or a computer by wireless, and may transmit information values of a swing direction and a trajectory to the user through the sensing unit 35. The communication unit 37 may include a bluetooth module or a transmission/reception connection cable.

The control module 30 may further include a CPU 38.

The CPU38 is provided to be electrically connected to the board 32, and processes the information value of the position signal based on the swing direction and the trajectory of the user measured by the sensor unit 35. The information on the position signal according to the direction and trajectory of the user's swing processed by the CPU38 may be transmitted to a smartphone or a computer through the communication unit 37.

The information of the swing direction and the trajectory-to-position signal transmitted to the user of the smart phone or the computer can be compared with the swing data of the first-class player, and particularly, the score of the swing posture can be calculated by comparing the degree of the deviation from the trajectory. For this purpose, discrete mathematics can be utilized.

The user can confirm the result of the practice of the swing through the smart phone or the computer by the control module 30, thereby performing feedback to help modify the swing speed, swing track and the like and improving the swing ability.

The invention has the advantages that:

the table tennis bat device for practicing swinging of the bat of the invention can adjust the weight of the bat according to the swinging capacity of the table tennis bat by arranging the heavy object in the accommodating part.
