Table tennis practice apparatus having a ball collecting network {TABLE TENNIS PRACTICE APPARATUS WITH BALL COLLECTING NET}

The present invention relates to a table tennis practice device, and more particularly, to a table tennis practice device having a ball collection network to facilitate ball collection.

Recently, a ping-pong practice device that can be easily installed on a ping-pong table to practice ping-pong has become common. This table tennis practice device is convenient to exercise alone and is a very effective exercise device that can hit a lot in a short time. By using these practice devices, beginners can easily learn the basics, and advanced players can train and warm-up.

Currently, many ping-pong practice devices having a machine for spraying a plurality of ping-pong balls at regular intervals are commercially available, an example of which is shown in FIG. 1 .

1 is a view showing a general table tennis practice device.

Referring to Figure 1, the ping-pong practice device is a court (2), a net (4), a net (6) for preventing the ping-pong ball from bouncing in all directions, and a device for spraying the ping-pong ball to the trainer at regular intervals (10) includes

Most of the practice devices of this configuration are too large in size and not only occupy a lot of space when used in a general home or table tennis practice room, but are also difficult and inconvenient to transport due to their heavy weight. In addition, since many ping-pong balls are scattered around, they tend not to be used frequently because of inconvenience to the surroundings, and the collection rate of used ping-pong balls is not high. When using a device that sprays multiple ping-pong balls, the ping-pong balls bounce off the opponent’s table and collide in the air with the ping-pong balls that are thrown from the device, stay on the opponent’s table, or some of them cannot cross the net and stay on the table. . Ping-pong balls that are not recirculated in this way have disadvantages in that exercise time is disturbed and inconvenient because people have to go and collect them themselves.

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 increase the collection rate of ping-pong balls, thereby reducing the hassle of collecting ping-pong balls, saving time, and providing a ping-pong practice device that can be easily installed and utilized even in a small office or home.

Table tennis practice apparatus according to an aspect of the present invention, a court provided on the side of the practitioner; a ping-pong ball projecting device located on the opposite side of the court to spray the ping-pong ball to the practitioner; a net-type bed provided to correspond to the coat portion from the opposite side of the coat; It is characterized in that it includes a frame surrounding the mesh bed, and a collecting network surrounding all sides of the frame except the front side of the practitioner side.

The collection network is disposed on the opposite side of the coat unit, the four corners of the collection network are coupled, and the frame is coupled to extend upward of the collection network to form a hexahedral structure; and a net structure surrounding the frame.

The collecting net and the bed have a net structure.

The mesh-type bed is to replace the opponent's coat, and it is preferable to have a mesh larger than the diameter of the ping-pong ball to pass the ping-pong ball.

The collection network is preferably installed so as to surround the surface except for the front side of the practitioner side of the hexahedron-shaped structure formed by the frame.

The coat unit has a size of 1/2 to 1/4 of the official table tennis table, and the mesh-type bed preferably has the same size as the coat unit.

It is preferable to further include a net installed between the coat unit and the collecting net, and the net is installed to be spaced apart from the coat unit by a predetermined distance. At this time, in order to collect the ping-pong ball sent by the practicer when the ping-pong ball falls down on the net, it is preferable that the collecting net protrude toward the court so as to fill the gap.

It is preferable that the frame is inclined so that the hexahedral shape of the frame has a wider trapezoid on the side closer to the net.

Installed between the net and the bed, it may further include an LED bar (bar) to visually confirm the ping-pong ball falling on the bed.

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

According to the present invention, the size and weight of the table tennis practice device can be significantly reduced by reducing the size and weight of the court part, which occupies the size and weight, to about 1/4 the size of the existing table tennis table, so that practice is possible in many places without space restrictions, Easy to move and install. In addition, it is possible to easily collect ping-pong balls by installing a net-type bed for catching ping-pong balls and a collecting net instead of the court opposite the practicer.

2 is a view showing a table tennis practice device 100 having a ball collection network according to the present invention, Figure 3 is a view showing a comparison of the size of the table tennis practice device of the present invention and the conventional table tennis practice device, Figure 4 is a view showing the ball collection network of the table tennis practice device according to the present invention, Figure 5 is a view showing the ball collection network part of the table tennis practice device according to the present invention in detail, Figure 6 is a table tennis practice device according to the present invention It is a drawing showing the process of collecting ping-pong balls.

First, referring to FIG. 3 showing the comparison of the size of the conventional table tennis practice device (A) and the table tennis practice device (B) of the present invention, the size of the general authorized table tennis table (A) is the length (L1 × 2) It measures 2740 mm, the width is 1525 mm, and the height is 760 mm. However, since it is not common around us to have a space that can accommodate such large equipment or furniture, there are a lot of space restrictions in practicing ping-pong. If the size of the table tennis table can be reduced, a lot of space constraints can be alleviated.

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

Referring now to Figure 2, the ping-pong practice device 100 according to the present invention is a ping-pong ball automatic projection device 10 that automatically projects a ping-pong ball to the practitioner, and the ping-pong ball falls from the automatic projection device 10 A court 20 including a point, a collecting network 30 that prevents the ping-pong ball projected from the projection device and the ping-pong ball hit by the practicer from flying out of the bouncing, and positioned opposite the court to receive the ping-pong ball from the practicer It includes a mesh bed 40 that allows the friendly ping-pong balls to be collected down without bouncing, and a frame 32 for fixing the collecting net and the mesh bed. In addition, a net 50 positioned between the court 20 and the bed 40, and a container 80 positioned under the bed 40 to collect and accommodate the collected ping-pong 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 practitioner is located, and the interval and direction at which the ping-pong balls are projected can be adjusted for effective practice.

The court 20 is a place where the ping-pong ball flying from the automatic ping-pong ball projection device 10 falls first, and where the practitioner strikes back the bouncing ping-pong ball. As seen in the comparative drawing with the conventional table tennis practice device (A) shown in Figure 3, the court 20 in the table tennis practice device 100 of the present invention is significantly smaller in size with a width of about half of the conventional court It can be seen that lost When practicing table tennis using the device 10 for automatically projecting the ball, since the practitioners mainly use it as learning posture and sense by repeating the action of quickly receiving a ball flying in a certain direction, the court 20 ), even if the width is reduced to half or less, the effect of practice can be sufficiently achieved. In addition, in the case of the conventional table tennis table (A in Fig. 3), it is costly and manpower is required to transport it because it is large in size and has a considerable weight, but if the size of the court 20 is reduced by half as in the present invention, the existing Compared to the ping-pong table of the table tennis table, its size is reduced to almost 1/4, so it is much easier to carry.

The collecting network 30 and the mesh-type bed 40 allow the ping-pong ball projected from the automatic ping-pong ball projecting device 10 or the ping-pong ball hit by the practicer to be collected at the bottom without flying out to the outside. That is, by letting the ping-pong ball fired from the automatic projection device 10 or the ping-pong ball hit by the practicer fall to the net-type bed 40, the ping-pong ball is prevented from flying to the outside of the practice device. In order to configure the collecting network 30, the frame 32 and the connection part 34 are used to form a box shape, and then the collecting network 30 is installed to cover the remaining surfaces except for the front side adjacent to the net.

In the case of the conventional ping-pong practice device shown in Figure 1, even if the collection network 6 is present, the upper side is open, so the ping-pong balls hit by the practicer jumped out, making it difficult to collect. However, as shown in FIGS. 2 and 5, in the case of the collecting network 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 practitioner side, the ping-pong balls through the upper or side part It is impossible to jump out. The collecting network 30 may be in the form of a net, but even if it is composed of a thin plastic plate, a sufficient effect can be obtained. The plate-like shape is one of plastic plates with high transmittance, and may be, for example, any one of PET, PC, PVC, and TPU.

The net-type bed 40 is installed on the other side of the court 20, where the ping-pong ball hit by the practitioner falls, and the four corners are tied to the frame 32 and installed in the form of a bed. The mesh bed 40 has a mesh structure so that the ping-pong ball easily exits the bed and goes down to the collection container 80 below, as shown in FIG. 4, a mesh 42 larger than the size of the ping-pong ball. It is preferable to have The net-type bed 40 may be installed with a size of 1/4 of the size of a conventional table tennis table, approximately 1680 mm in length, and 763 mm in width, similar to the court 20 . In addition, the size of the mesh (42 in Fig. 4) of the mesh bed 40 is more than 40mm to 50mm or less, so that a ping-pong ball having a diameter of 40mm can easily escape and be collected in the collection container 80 below. Instead of the mesh-shaped bed 40 of the present invention, the same effect can be obtained by installing a plastic plate on which a mesh grid is formed. In addition, the collecting net may be replaced with a transparent and thin plastic instead of a net. Because it is transparent, it is easy for the practicer to see where the ball is going.

As mentioned, the collecting 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 that is a connection joint of a pipe. Preferably, the frame 32 can be easily disassembled and assembled for easy transport and installation. The frame 32 may have a rectangular shape for convenience in manufacturing, or may have other shapes such as trapezoid or circular shape.

According to the present invention, the inclination of the side frame is about 10 to 20 degrees, but the most ideal angle of the side frame is to be inclined at 12 to 15 degrees, and the open direction of the part close to the net 50 is the largest. it will be gone By tilting it at this angle, it naturally collects the ping-pong ball that hits the net and falls down. In other words, for the movement of the ping-pong ball hit by the practitioner, a wider space is provided in the part close to the net, and the edge close to the ping-pong ball projection device goes down further to provide a slope so that it can flow well.

The frame 32 may be constructed using a pipe, and the corner portion may be coupled using a joint commonly used to connect the pipes, that is, the connecting portion 34 . In general, joints having an angle of 90 degrees, that is, connecting parts are commercially available, which is convenient for manufacturing. As a material of the pipe and the connection part, plastic is preferable, for example, PVC, PE, PP, or FRP is suitable, and as the metal, stainless steel, a painted steel pipe, etc. may be used. Since the weight of the collecting net 30 and the mesh-type bed 40 is light and does not receive a large force, a plastic frame and a connection part may be used.

The frame 32 is, as shown in FIG. 4, each terminal 64 so that it can be used when installing the LED bar 60, when fixing the net 50, or when installing the mesh bed 40. ) to be inserted. In the present invention, a pipe having a diameter of about 20 mm was used, and terminals 64 that can wrap the outer surface of the pipe were made to be connected to the net-type bed 40 by a string 46 and fixed. The frame 32 is preferably black so as not to reflect the LED light.

Referring back to FIG. 2 , a net 50 is installed between the court 20 and the net-type bed 40 , and a container 80 for accommodating the ping-pong balls in one place under the net-type bed 40 is provided. is installed

In the table tennis practice device 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 string 46 connected to the terminal 64 . In general, since the height of the net 50 is about 152.5 mm, it is installed at the same or similar distance (L3 in FIG. 3) from the court 20 to the height of the net. The reason is that, when the ping-pong ball hit by the practicer falls off the net 50, it falls on the court 20 and does not go out to the outside, but goes down between the gaps (L3) and is a collection container (80) by the net under the net-type bed (40). ) to be collected. Accordingly, the lower end 32-2 of the frame is installed below the height of the court.

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

The LED bar 60 is installed so that the practitioner can visually clearly see the ping-pong ball hit. A plurality of light emitting diode lamps are disposed on the LED bar 60 and are installed detachably from the rear of the net 50, that is, at a place further away from the court 20 than the net 50, replacing the LED bar with a laser bar. can be By using a laser or LED light to brightly illuminate the ping-pong ball falling on the net-type bed 40, the practitioner can confirm the drop position of the ping-pong ball. For example, as shown in FIG. 4, when using a red LED, a ping-pong ball (70 in FIG. 4) is a net-type bed by irradiating horizontally parallel light directly on the net-type bed 40 from the net. By seeing it turn red before reaching (40), you can tell the location of the fast-flying ping-pong ball. This visual effect can cause interest by giving a dramatic feeling to the practitioner at the same time as confirming the drop position of the ping-pong ball 70 in the net-type 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, among the red LED lamps, it is better to use those with a small spreading angle. It is known that the LED lamp having the narrowest irradiation angle among LEDs currently on the market is about 3 degrees. A plurality of such LED lights are installed to illuminate the upper portion of the mesh-type bed 40 by installing a bar 60 . By minimizing the angle of divergence with the help of the lens, the brightness effect of the reflected light can be maintained. When installing, the LED bar 60 can be connected by inserting a connection part to the tube of the frame so that it can span both sides of the frame 32 . The LED bar is for interest and visual effect, and may be optional rather than an essential element of the present invention.

6 is a view showing a process of collecting ping-pong balls in the ping-pong practice device according to the present invention.

6, the ping-pong ball 70 fired from the automatic ping-pong ball sighting device 10 falls on the court 20 first, and bounces back by the repulsive force with the court, and the practitioner jumps the ping-pong ball 70 ) is returned. The ping-pong ball 70 goes over the net 50 and falls on the net-type bed 40 corresponding to the opponent's court. At this time, even if the ping-pong ball that is continuously being fired from the automatic projection device 10 collides with the ping-pong ball hit by the practicer, it falls to the net-type bed 40 by the collecting net. The ping-pong balls that fell on the net-type bed 40 fall into a net larger than the diameter of the ping-pong balls formed on the net-type bed 40, and are collected in one place through a collecting net installed under the net-type bed and collected in the collection container 80.

As described above, according to the table tennis practice device of the present invention, the size and weight of the table tennis practice 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 the space constraints. It is possible to practice in many places without the need for it, and it is easy to move and install. In addition, by removing the court opposite the practicer and installing a net bed instead, the ping-pong ball can be easily collected without difficulty.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited thereto, and it is possible to carry out various modifications within the scope of the detailed description of the claims and the invention and the accompanying drawings, and this also It is natural to fall within the scope of
