Description

  The present invention relates to a table tennis practice table that can practice table tennis alone.

  Table tennis requires advanced techniques such as rally exchange of speedballs and changing ball serve, as well as quick reaction and movement of the body, as seen in games such as the All Japan Table Tennis Championship and the World Table Tennis Championship when becoming the top player in Japan. Although this is a sport, table tennis as a sport enjoyed by the general public and as a health method does not require such skill or body movement. Table tennis performed by ordinary people is a table tennis that anyone can enjoy as a recreational sport, ranging from beginners who are appropriate to be called ping-pong to intermediate-level skills that can be used to handle the ball and continue driving and rallying to some extent Is wide, and the practice method naturally changes accordingly.

  It is said that table tennis, which has a moderate amount of exercise and uses the body in a well-balanced manner, is a whole body exercise sport that requires an instantaneous power for the ball that the opponent hits back, and is good not only for the health of the body but also for activating the brain. In competitions, there are doubles in which two people form a pair and four people play, but in general table tennis enjoyed by ordinary people is played by one person and one opponent. Table tennis is a so-called easy-to-attach sport that can be enjoyed normally with a table tennis table, racket, and ball.However, the practice content is advanced from the elementary stage as a recreational sport to improve the skills with the aim of participating in the tournament. The stage is wide and wide. However, no matter what stage of practice, when you go to the place where the ping-pong table is provided, it is the reality that there is hardly any place equipped with equipment specialized for sole practice.

Japanese Utility Model Publication No. 54-089967

  The table tennis practice table of the present invention aims to provide a table tennis table where players can practice serving, hitting, receiving, rallying, etc. alone without an opponent, and the ball hit by the player toward the opponent's court, The goal is to return to the player without jumping out of the court. This allows the player to concentrate on the practice of hitting without picking up the ball, and the purpose of providing this table tennis practice table is there.

  As set forth in claim 1, the table tennis practice table of the present invention has two courts formed by attaching a net that can be lifted up at the center of the table top of the table tennis table, and a leg inserted under the table tennis table leg. On the top plate that is gently lowered and inclined from the opponent's court to the near side court by the high adjustment tool, along the left and right ends of the ball rebounding plate provided along the end line of the opponent's court, along both side lines of the court Attach the side plate that extends to the net at the center of the top plate, provide a side guide that extends from the central net to the coat end line along both side lines of the near side court, continue extending the side guide as it is and exceed the end line It functions as an outer frame of a ball receiving portion that protrudes.

  The table tennis practice table of the present invention has been devised to minimize the possibility of the ball jumping out of the court during practice. The ball hit by the player toward the opponent's court is bounced back by the bounce board and returned to the player's hand, and the ball that is about to jump out to the side of the court is pulled back into the court by the side board and rolls over the court and passes through the net. The player can always keep the ball at hand, for example, along the side guide or directly into the ball receiving part, so that he can concentrate on practice without having to go to pick up the ball significantly .

  It is a perspective view of the table tennis practice table which formed the side board with net material.   It is the elements on larger scale side view near the net attachment seen from the Ca coat side.   It is a top view of a table tennis practice table.   It is the side view of the table tennis practice table which changed the shape of the side plate and expanded the area.

Embodiment

  First, let me explain the terms used in this section. The white lines drawn on the tabletop along the both ends in the depth direction of the tabletop table are called side lines, and the white lines drawn at the front and rear in the width direction are called end lines. Regarding the court, the near side court is referred to as Ca and the other side court is referred to as Cb. FIG. 1 is a perspective view showing a table tennis practice table according to an embodiment of the present invention, in which six side plates are formed of a substantially triangular net material. The two top boards of one table tennis table are gently inclined downward from the end line of the Cb coat to the end line of the Ca coat by a twelve leg height adjuster inserted below the four legs. When practicing using this ping-pong table, 14 players stand near the end line of the Ca-court of one ping-pong table with 15 balls in hand, and hit a racket toward the Cb court side. Some 15 balls hit the 5 bounce board and then return to the Ca coat, while others roll on the Cb coat to reach 3 nets. The 15 balls that rolled into the Ca coat through the 11 net openings of the 3 nets directly enter the 8 ball receiving portion, or rolled in the end line direction along the 7 side guides provided on the left and right sides of the Ca coat to receive 8 balls. Housed in the department.

  The hit 15 balls fly infinitely depending on the strength, direction, height, etc. of the hit ball. In any case, the 15 balls finally return to the 8-ball receiving portion by the action of the 5 bounce plate, the 6 side plate, the 3 nets, and the 7 side guides. Depending on how the ball is bounced by 15 players and how it is received by 14 players, some may jump out of one ping-pong table or fall to the floor surface. I have. The percentage of the ball that hits will return to your hand, depending on the skills of the 14 players who practice, but if 80 to 90% return, it is worthwhile to use this practice table.

  (5) The material of the bounce plate may be any of a resin plate, a metal plate and the like in addition to a wooden plate. In any case, since the plate surface is hard and the coefficient of restitution is high, a quick rebound speed is required, and a quick response and operation to receive are required. That's a good practice, but it's also possible to stick the same rubber on the surface of the 5-bounce board as the one on the racket. In this way, the virtual opponent, a 5-bounce board, becomes an opponent who hits back with a racket on which rubber is stuck, and the hitting and receiving state of the ball approaches actual battle, so that the practice becomes real.

  The six side plates made of nets provided on both sides of the Cb coat are U-shaped when attached to the five bounce plates with hinges, and are self-supporting, and are easy and convenient to remove and carry. It is necessary to surround the net material with a wooden frame, a resin frame, a metal frame, or the like so that the six side plates formed of the net material can be self-supporting so that the form can be maintained. As for the material of the net, if it is flexible, what kind of material is used if it is a flexible material such as cloth, paper, or resin sheet as well as resin (vegetable fiber net) It doesn't matter. If the ball hit by 14 players bounces on the 5 bounce plate and hits the 6 side plate, the impact of the ball is relieved by the net, so the speed of the ball is likely to decrease rapidly and fall on the court in many cases. In this case, the rally cannot be continued, but it is convenient because the ball that would normally jump out of the court is secured in the court and returned to 14 players.

  The six side plates are generally triangular in FIG. 1, but as shown in FIG. 4, the area of the triangle is increased to increase the ball catching rate by increasing the center of the triangle or making it square instead of triangle. Is also possible. However, from the viewpoint of 14 players, if the area of the 6 side plates is too large, a negative surface may be felt, so that it is necessary to determine the shape in consideration of the sides.

  It is also possible to use a wood, resin or metal plate instead of a net as the material of the 6 side plate, but if such a hard material is used, the coefficient of restitution increases and the movement after reflection of 15 balls becomes faster. In addition, the direction in which the ball flies becomes unstable, and the movement is impossible for a 14-player to be able to do in a real battle. However, the six side boards are not installed in the actual game of table tennis, and their role is only to keep the ball out of the court during practice, so it is not much of a problem if you can not receive.

  It is the raising of 3 nets shown in Fig. 2, but the lower 1/3 of the 3 nets is raised so that the 15 balls rolling on the Cb court are not stopped by the 3 nets. make. Since the diameter of the ball is 40 mm, the height of the tunnel need only be about 50 mm above the court. As a method of raising the 3 nets, use 3 to 4 cloth or resin 10 net bands, such as miniaturized armbands, or use a net box in a narrow and narrow box-shaped container and place it on the top plate. (Not shown). Whichever method is used, a method that can be easily attached and detached and that can be performed in a short time is preferable.

  If the net is knocked up, the 15 balls will pass under the net, but if the 15 balls roll on the part where the 13 net mounting bracket protrudes on the court, it will catch on the bracket and stay there There is fear. To prevent this, a 9-ball guard having a slope for covering the metal fittings and allowing the ball to escape to the center of the court is attached (see FIGS. 2 and 3). It is easy and convenient to attach the back of the 9-ball guard to the 6-side plate and the 7-side guide with surface tape.

  The 7 side guides installed on both sides of the Ca court on the 14 player side have the role of guiding the rolling 15 balls and sending them to the 8 ball receiving section, but the 7 sides after bounding and entering the Ca court It is possible to jump over the guide and go out of the court. The 7 side guide may be raised to some extent to prevent it, but if it is too high, it will visually or hamper the 14 player's receiving operation, so usually it will be about 3 cm above the 2 tops, I want to keep it at most 3 nets high (see Figure 4). The material is not only a guide for the 15 balls, but also a role as an outer frame of the 8-ball receiving portion. Therefore, a long wooden board which can maintain a firm shape and has no warp is suitable.

  A U-shaped portion protruding from the coat by 5 to 6 cm along the end line of the Ca coat is formed as an 8-ball receiving portion. The size of the 8-ball receiver is about 152cm in width, about the same as the width of the end line, about 5-6cm in length, and 3cm in height of the side guide + 2cm in thickness of the top plate, about 5cm in total. And pretty elongated. The bottom surface is the same surface as the lower surface of the top plate, the 7 side guides are extended as it is to the Ca end line, and from there, the top plate thickness 2 cm is added to the lower part and along the periphery of the ball receiving part Form side surfaces 5 cm high. The ball receiving portion formed in this manner has a capacity to accommodate a maximum of 37 balls of 4 cm in diameter arranged in one row due to the thickness of the peripheral wall. It is necessary to prepare dozens of balls in the practice of extending only the serve from one to the next, but in the practice using this table tennis practice table, a series of actions such as receiving the served ball and playing a rally Is performed by one person, and when the movement is over, 15 balls roll on the inclined court and enter the 8 ball receiving portion. Depending on the skill level, if there are about 10 balls, This is a sufficient practice method. It can be said that it is too much to accommodate as many as 37 balls, and it may be easier to play if the ball receiver does not protrude too far from the court.

  The 5 bounce plate and the 6 side plate used as the ball bounce device in the present invention are not set up from the floor surface, but are placed on the 2 top plate. This is to make it easy to remove when switching from single practice to two-person practice. Of course, if you just put it, it will move when the body of 14 players hits the top board, etc., so it may be lightly fixed to the two top boards with a clasp. This is because the 15 balls are lightweight and do not receive a large force even if they directly hit the 5 bounce plate or the 6 side plate, and it is enough to keep them lightly.

  In addition to the above-mentioned 5 bounce plates and 6 side plates, it is desirable to adopt a form in which the 7 side guides on the Ca coat and the connected 8 ball receiving portions are simply placed on the top plate so that they can be easily removed. As described above, when switching from single practice to two-person practice, all the equipment attached to the ping pong table can be quickly and easily removed and quickly replaced with a normal ping pong table. It is. In other words, although this table tennis table focuses on the use of table tennis practice for one person, it is not necessary to move to another table tennis table when two people want to practice table tennis together, It is possible to continue pairing at the ping pong table for solo practice that had been conducted until now.

  In the present invention, a twelve leg height adjuster is inserted at the lower end of the four legs so that the hit ball can be rolled gently on the two top plates, the legs are raised, and the court is gently inclined. I have. Specifically, a twelve leg height adjuster with a height of 5 to 6 cm, which is the highest in the left and right legs below the end line of the Cb coat, is inserted. Do not insert anything into the two legs below the Ca-coated end line. In this way, after the ball hit from the Ca court is bounced off, even if it falls on the top plate, it rolls slowly and returns to the hands of 14 players. The height of the four legs at the center may be different from that of the other two legs. However, a step is formed at the boundary between the Ca and Cb coats, and it is not good.

  The above-mentioned table tennis practice table is a formal table tennis table equipped with necessary equipment for training, but even if a formal top board is not available, we want to ensure that the depth of the top board is regular . This is because the player can feel the distance between the balls. The width and height need not be formal, but may be any flat plate that can hit the ball with a racket. For example, when using the control panel, it is 180 cm deep x 90 cm wide, which is considerably smaller than the official table tennis table (depth 274 cm x 152.5 cm wide). Good. A special bounce board, side board, net, side guide, and ball receiving section are provided for this, and if you can make the board surface gently with a leg height adjustment tool that raises the legs, it is a reasonable training top plate (Not shown).
