Description

[Detailed explanation of the invention] (Purpose of the invention) This invention relates to a practice swing practice tool for table tennis, in which a swing guide bar is installed at a desired angle according to the purpose, and the practice swing is practiced along this guide bar. It is characterized by the following.

(Prior Art) Conventionally, when practicing table tennis practice swings, a coach initially instructs each player the desired form and angle of practice swings and has them repeat the practice swings. There is no accompanying coach, and the practitioner must follow the initial instructions and continue practicing independently in front of the mirror. However, even if you think you are practicing with the same form, as time passes, you start practicing in your own way, and the reality is that you are unable to continue practicing as originally instructed, and this tendency is especially noticeable for beginners.

Although practice swing practice is the basis of table tennis and is an extremely important practice, there was no practice equipment available at all.

(Structure of the invention) In view of the above-mentioned circumstances, the present invention is designed to enable even beginners to practice continuously without losing their form.One embodiment of the invention will be described below with reference to the drawings.

In the figure, reference numeral 1 denotes a column, and the lower part of this column is inserted into a pipe stand 2 so as to be able to slide up and down, and can be fixed at an arbitrary height with screws 3. Further, as shown in FIG. 3, a threaded rod 4 and a support pin 5 are provided in a projecting manner on the upper and lower sides of the upper side surface of the support column 1.

Reference numeral 6 denotes a swing guide rod having an arcuate planar shape, and a fixing plate 7 is provided at the lower center of the rod along the guide rod, and this fixing plate has a hole 8 at the lower center as shown in FIG. An arcuate long hole 9 centered on the hole is provided at its upper part. As shown in FIG. 3, the support pin 5 and threaded rod 4 on the upper part of the column are passed through the hole 8 and the arcuate long hole 9 in the fixing plate, respectively, as shown in FIG.
Both ends of the swing guide rod 6 are attached to be movable up and down like a seesaw, and the swing guide rod 6 can be fixed at any angle with a thumbscrew 10 provided at the tip of the threaded rod 4.

On the other hand, the lower part of the stand 2 is fixed near one corner of a rectangular frame 11 made of iron pipe, and a scale 12 is provided on the upper part of the periphery of this rectangular frame to memorize or indicate the proper position of the feet. It has been designed to be convenient.

However, the support form of this stand 2 should not be limited to the embodiment shown in the drawings, but any suitable structure can be considered.

The material of the swing guide rod 6 in the present invention may be an iron pipe, an aluminum pipe, or a hard synthetic resin pipe, and the radius of curvature of the arc is, for example, about 50 to 60 cm for drive driving, and the length of the swing guide rod. A height of about 140 to 150 cm is sufficient. In addition, in the case of short shots, a radius of curvature of 30 to 40 cm and a guide rod length of approximately 80 cm are sufficient, but these dimensions should be adjusted to suit each practice swing depending on the type of practice. Prepare several types
It may be replaced as appropriate depending on the purpose of the exercise.

In addition, the means for fixing the swing guide rod and the pillar can be of various structures, including a supporting method using a pivot journal in addition to the above embodiment, but the following describes the angle-adjustable structure of this swing guide rod and its fixing means. It is not particularly limited either.

(Effects of the invention) Since the present invention has the above-described configuration, the height of the support 1 can be adjusted according to the height of the practitioner, and the angle of the swing guide rod 6 can be adjusted using the thumbscrew 10 according to the purpose of practice. By adjusting the racket and swinging the racket along the swing guide rod 6, practice swings using the same form can be continuously practiced. Therefore, it is especially useful for beginners in making forms.

Further, in the present invention, since the swing guide rod 6 can be set with either the left or right side up or down, it can be used for either right-handed or left-handed batters, as well as for either front-hand or back-hand.

Furthermore, for advanced players, it can be used to train muscle strength by practicing swings with an iron array, and the types of practice swings include front attack, drive strike, smash hit, short shot strike, loop strike, and cut strike. It can be applied to various practice swings such as.

As described above, the present invention has a simple structure, can be provided at low cost, and is lightweight and easy to carry, so it has great utility value and high industrial applicability.
