Referring to Figure 1, the apparatus for practicing table tennis includes a court (2), a net (4), a net (6) for preventing ping pong balls from bouncing in all directions, and a device (10) for spraying ping pong balls to the trainer at regular intervals Includes.

Most of the exercise devices of this configuration are too large to occupy a lot of space when used in a general home or table tennis practice room, and it is difficult and inconvenient to carry due to the heavy weight. In addition, since many ping pong balls are scattered around, there is a tendency that they are not often used because of inconvenience, and the collection rate of used ping pong balls is not high. If a device that sprinkles multiple ping pong balls is used, the ping pong balls bounce off the opponent's table and collide with the ping pong balls sprinkled from the device in the air, remain on the opponent's table, or some of them cannot cross the net and collide and stay on the table. . Table tennis balls that are not recycled like this have the disadvantage of being disturbed and inconvenient because people have to go and collect them.

As an example of such a table tennis table, Korean Patent Registration No. 10-1799209 (registered on November 13, 2017) discloses a smart table tennis table and an in-out determination method using the same.

The problem to be solved by the present invention is to provide a table tennis practice device that can be easily installed and utilized in a narrow office or home, reducing the hassle of collecting table tennis balls by increasing the collection rate of table tennis balls, saving time.

The collection net is disposed opposite the coat part, the four corners of the collection net are coupled, and the frame is extended upwardly to form a hexahedral structure; And a mesh structure surrounding the frame.

The collecting net and the bed have a net structure.

The net-shaped bed is to replace the coat portion of the other side, and it is preferable to have a mesh larger than the diameter of the table tennis ball so as to pass the table tennis ball.

It is preferable that the collection network is installed to surround a surface other than the front side of the trainee side of the hexahedral structure formed by the frame.

The coat portion has a size of 1/2 to 1/4 of the official table tennis table, and the net-shaped bed preferably has the same size as the coat portion.

A net installed between the coat unit and the collection net is further included, and the net is preferably installed at a predetermined distance from the coat unit. At this time, it is preferable that the collection net protrudes toward the court so as to fill the gap in order to collect the ping pong balls when the ping pong balls sent by the trainer are caught by the net and fall down.

As for the hexahedral shape of the frame, it is preferable that the frame is inclined so that the side closer to the net has a wider trapezoid.

It is installed between the net and the bed, it may further include an LED bar (bar) to visually check the table tennis ball falling on the bed.

In the lower part of the bed including the lower part of the net, a net for guiding the table tennis balls passing through the bed may be further installed.

The present invention may be implemented in a number of different forms, and is not limited to the embodiments described herein. The same reference numerals are assigned to the same or similar components throughout the present specification. In addition, detailed descriptions of known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

This 2 is a view showing a table tennis training apparatus 100 having a ball collection net according to the present invention, Figure 3 is a view showing a comparison of the size of the conventional table tennis practice device and the table tennis practice device of the present invention, 4 is a view showing the ball collection net of the table tennis practice device according to the present invention, Figure 5 is a view showing in detail the ball collection net portion of the table tennis practice device according to the present invention, Figure 6 is in the table tennis practice device according to the present invention It is a diagram showing the process of collecting table tennis balls.

First, referring to Figure 3, which compares the sizes of the conventional table tennis practice device (A) and the table tennis practice device (B) of the present invention, the size of a general authorized table tennis table (A) is a length (L1×2) It is 2740 mm, width 1525 mm, and height 760 mm. However, since there is not a lot of space around us to hold such large equipment or furniture, there are many space restrictions for practicing table tennis. If the size of the table tennis table can be reduced, space constraints can be greatly relaxed.

In the case of practicing table tennis using the device 10 that automatically sprinkles the ball, most of the practitioners use it mainly to learn posture and sense by repeating the motion to quickly catch a ball flying in a certain direction. It does not have to be as large as the existing table tennis table shown in 3(A). Therefore, as shown in (B) of FIG. 3, even if the length (L2×2) of the table tennis table is kept as it is and the width is reduced to about half, the effect of the practice can be sufficiently achieved.

Referring now to FIG. 2, the table tennis practice device 100 according to the present invention includes an automatic table tennis ball projection device 10 for automatically projecting a table tennis ball to a trainee, and a table tennis ball falling from the automatic projection device 10. A court 20 including a point, a collection net 30 that prevents the ping pong balls projected from the projection device and the ping pong balls hit by the trainee from splashing and flying to the outside, and positioned opposite the court to receive the trainee It includes a net-shaped bed 40 that allows the ping pong ball to be collected downward without splashing, and a frame 32 for fixing the collecting net and the net-shaped bed. In addition, it further includes a net 50 positioned between the coat 20 and the bed 40, and a container 80 positioned below the bed 40 to collect and accommodate the collected table tennis balls in one place. do.

The automatic ping-pong ball projection device 10 is a device for automatically projecting ping-pong balls at regular intervals to the court 20 where the trainer is located, and the interval and direction in which ping-pong balls are projected can be adjusted for effective practice.

The court 20 is a place where the table tennis ball flying from the automatic ping pong ball projection device 10 first falls, and is a place where a practitioner takes back a bouncing table tennis ball. As shown in the comparative drawing with the existing table tennis practice device (A) shown in FIG. 3, in the table tennis practice device 100 of the present invention, the coat 20 is about half the width of a conventional coat and is significantly smaller in size. You can see that you lost. In the case of practicing table tennis using the apparatus 10 for automatically projecting the ball, the practicers are mainly used to learn posture and sense by repeating the motion to quickly catch the ball flying in a certain direction, so the court 20 Even if the width of) is reduced to half or less, the effect of the exercise can be sufficiently achieved. In addition, in the case of the existing table tennis table (A in Fig. 3), the size of the table tennis table (A in Fig. 3) is large and the weight is significant, so transportation costs and manpower are required. Compared to the table tennis table, the size of the table tennis table is reduced to almost 1/4, making the transportation work much easier.

The collection net 30 and the net-shaped bed 40 allow the table tennis ball projected from the automatic table tennis ball projection device 10 or the table tennis ball hit by the trainer to bounce and be collected downward without flying to the outside. That is, the table tennis ball fired from the automatic projection device 10 or the table tennis ball hit by the trainer falls to the net-shaped bed 40, thereby preventing the table tennis ball from flying out of the exercise device. In order to configure the collection network 30, the frame 32 and the connection part 34 are used to form a box, and then the collection network 30 is installed to surround the remaining surfaces except for the front side adjacent to the net.

In the case of the conventional table tennis practice device shown in FIG. 1, even though the collection net 6 is present, the upper side is open, so that the table tennis balls hit by the trainee protrude outward, making it difficult to collect. However, as shown in Figs. 2 and 5, in the case of the collection net 30 of the table tennis practice device according to the present invention, since it is installed to surround all surfaces except the front side of the trainee side, the table tennis balls are It is impossible to stick out. The collection net 30 may be in the form of a net, but a sufficient effect may be obtained even if it is formed of a thin plastic plate. As a plate shape, one of plastic plates having high transmittance, for example, may be any one of PET, PC, PVC, and TPU.

The net-shaped bed 40 is installed on the opposite side of the court 20, where the table tennis ball received by the trainee falls, and four corners are tied to the frame 32 and installed in a bed shape. The mesh bed 40 has a mesh structure so that the table tennis ball easily exits the bed and descends toward the collection container 80 below, as shown in FIG. 4, a mesh 42 larger than the size of the table tennis ball. It is preferable to have. The net-shaped bed 40 may be installed to have a size of 1/4 of the size of an existing table tennis table, approximately 1680 mm in length, and 763 mm in width, like the coat 20. In addition, the size of the mesh (42 in FIG. 4) of the mesh bed 40 is greater than 40 mm to 50 mm, so that the table tennis ball having a diameter of 40 mm easily escapes and is collected in the collection container 80 below. In place of the mesh-shaped bed 40 of the present invention, the same effect may be obtained by installing a plastic plate having a mesh grid formed thereon. In addition, the collection net can be replaced with transparent and thin plastic instead of the net. Because it is transparent, it is easy for the practitioner to see where the hit ball is moving.

As mentioned, the collection net 30 and the mesh bed 40 are fixed by a frame. The frame 32 is installed on the opposite side of the coat 20 and may be connected through a connection part 34 which is a connection joint of a pipe. It is preferable that the frame 32 can be easily disassembled and assembled to facilitate transport and installation. The frame 32 may have a rectangular shape for convenience of manufacture, or may have other shapes such as trapezoidal or circular shape.

According to the present invention, the inclination of the side frame is approximately 10 to 20 degrees, but the most ideal angle of the side frame is inclined at 12 to 15 degrees, and the open direction of the portion close to the net 50 is inclined to be the largest. I lost. By tilting at this angle, you can naturally collect the ping pong ball hitting the net and falling down. In other words, in order to move the ping pong ball received by the trainee, a wider space is provided at the portion close to the net, and the edge close to the ping pong ball projection device goes down further to provide an inclination so that it can flow well.

The frame 32 may be constructed using a pipe, and the edge portion may be joined using a joint commonly used to connect the pipe, that is, a connection part 34. In general, joints having a 90 degree angle, that is, joints, are commercially available, which is convenient for manufacturing. Plastic is preferable as the material of the pipe and the connection part. For example, PVC, PE, PP, or FRP is suitable, and as the metal, stainless steel, painted steel pipe, etc. may be used. Since the collection net 30 and the net-shaped bed 40 are light in weight and do not receive a large force, a plastic frame and a connection part may be used.

The frame 32, as shown in Figure 4, when installing the LED bar 60, when fixing the net 50, when installing the net-shaped bed 40, each terminal 64 ) To be inserted. In the present design, a pipe having a diameter of about 20 mm was used, and terminals 64 capable of wrapping the outer surface of the pipe were made to be connected to the mesh bed 40 with a twine 46 to be fixed. The frame 32 is preferably a black system so as not to reflect the LED light.

Referring again to FIG. 2, a net 50 is installed between the coat 20 and the net bed 40, and a container 80 for accommodating table tennis balls in one place under the net bed 40 is provided. Installed.

In the table tennis exercise apparatus 100 according to the present invention, the net 50 is not installed on the court 20, but is coupled to the frame 32. The net 50 is fixed to the pipe of the frame 32 using a twine 46 connected to the terminal 64. In general, the height of the net 50 is about 152.5mm, so it is installed at the same or similar distance as the height of the net from the coat 20 (L3 in FIG. 3). The reason is that, when the ping pong ball repelled by the trainer falls on the net 50, it falls on the court 20 and does not go outside, but goes down between the gaps L3 and the collection container 80 by the net under the net bed 40. ) To be collected. Accordingly, the lower end portion 32-2 of the frame is installed below the height of the coat.

Next, with reference to Figure 4 will be described in detail for the LED bar 60 installed in the table tennis practice device of the present invention.

The LED bar 60 is installed in order to clearly visually see the table tennis ball received by the trainee. The LED bar 60 is provided with a plurality of light-emitting diode lamps, and is detachably installed at the rear of the net 50, that is, away from the coat 20 and the net 50, replacing the LED bar with a laser bar. Can be. By using a laser or LED light to brightly illuminate the table tennis ball falling on the net-shaped bed 40, the practitioner can check the drop position of the table tennis ball. For example, as shown in Fig. 4, when using a red LED, a table tennis ball (70 in Fig. 4) is a net bed by irradiating horizontally parallel light directly above the net bed 40 from the net. Watching it turn red before reaching (40) allows you to locate the fast-flying table tennis ball. This visual effect can induce interest as it gives a dramatic feeling to the practitioner at the same time as confirming the drop position of the table tennis ball 70 in the net-shaped bed 40.

As the LED bar 60, a laser connected to an optical lens such as a prism or an array 62 in which a plurality of LED lamps and a cylindrical lens are arranged may be used. Preferably, it is better to use red LED lights with a small spreading angle. It is known that among the LEDs on the market, the LED having the narrowest irradiation angle is about 3 degrees. A bar 60 in which several such LEDs are arranged is installed to illuminate the upper part of the net-shaped bed 40. By minimizing the spreading angle with the help of the lens, the brightness effect of the reflected light can be maintained. When installing, it is possible to connect the LED bar 60 by inserting a connection part into the tube of the frame so that it can be spanned on both sides of the frame 32. LED bars are for intriguing and visual effects, and may be optional rather than essential elements of the present invention.

6 is a view showing a process in which the table tennis balls are collected in the table tennis exercise apparatus according to the present invention.

Referring to FIG. 6, the table tennis ball 70 fired from the automatic viewing device 10 for the table tennis ball first falls on the court 20, bounces back by the repulsive force with the court, and the trainer bounces the table tennis ball 70 ). Table tennis ball 70 falls over the net 50 to the net-shaped bed 40 corresponding to the opponent's court. At this time, even if the table tennis ball continuously fired from the automatic projection device 10 collides with the table tennis ball received by the trainee, it falls to the net-shaped bed 40 by the collection net. The table tennis balls dropped on the net bed 40 fall into a mesh that is larger than the diameter of the table tennis balls formed in the net bed 40, and are collected in one place through a collection net installed under the net bed and collected in the collection container 80.

As described above, according to the table tennis exercise device of the present invention, the size and weight of the table tennis exercise device are significantly reduced by reducing the size of the court occupying the size and weight to about 1/4 the size of the existing table tennis table, thereby reducing space constraints. It is possible to practice in many places without it, and it is easy to move and install. In addition, by removing the court opposite the trainee and installing a net bed instead, it is possible to easily collect the ping pong balls without difficulty.
