Description

The present invention relates to a device for collecting balls that get caught on the net during table tennis practice or are scattered around the net.

Traditionally, when a ball hits the net during table tennis practice, some balls stay close to the net and some balls fly off to the left and right sides of the table tennis table and fall. If it is necessary and affects neighbors, it must be picked up immediately.

As tools for collecting fallen balls during table tennis practice, there are known a net attached to the lower part of the outer periphery of a table tennis table (Patent Document 1) and a ramp device that guides balls from in front of the net toward the ball hitter (Patent Document 2).

In recent years, based on the concept of healthy life expectancy, table tennis, which can be played in a small indoor space in accordance with one's age, has been attracting attention, and with the table tennis boom, the number of people playing table tennis is increasing. For elderly people who enjoy playing table tennis, the act of collecting balls that scatter during play can be a burden.

Balls that stay near the net during table tennis practice can be left where they are, and the action of collecting balls on the table puts less strain on the lower limbs. However, picking up a ball that has scattered outside the stand must be done quickly if it affects the play of the adjacent player, and even if it is not urgent, it puts a heavy burden on the lower limbs and lower back, and wastes time. The element of enjoying the game is reduced.

Patent Document 1 proposes a device in which a net is placed around the lower part of the periphery of a table tennis table to reduce the number of balls falling onto the floor. The net that catches falling balls gets in the way, making it unsuitable for practitioners aiming to improve their technique.

Patent Document 2 proposes a method in which a tilting device provided inside the table tennis table net guides the ball caught in the net toward the ball hitter, but this method is limited to collecting balls that fall near the net. In addition, the slope device installed in front of the net makes it difficult to see the ball from the opponent's direction and makes it difficult to hit the ball near the net, which affects the improvement of technique.

In the present invention, as mentioned above, equipment other than the conventional table tennis table accessories, such as placing a net around the table and placing a slope on the table, is not placed around or on the table where the table is mainly played. It was developed so that players can continue to enjoy playing table tennis without having to set up a table tennis table, while improving their skills by practicing in accordance with the rules of the table tennis table, while also reducing the effort required to collect fallen balls.

A hanging hanger rail part of a hanging hanger (10) placed on the back side of a table tennis table top plate (1), which is a fallen ball collection box (12) that catches balls that hit the net and fall during table tennis practice. (11) By sliding the top surface, the falling ball collection box (12) can be moved in and out of the table tennis table top plate (1). ) The lower surface and the upper surface of the outer frame of the falling ball collection box (12) form a stable joint surface, making it possible to collect balls that are caught in the net and roll out, or balls that fly directly into the net. When the fallen ball collecting box (12) is not in use, it can be stored under the table tennis table top plate (1) by sliding and pushing the top surface of the hanging hanger rail section (11).

When folding and moving the table tennis table, it is necessary to remove the hanging hanger (10), but a magnet is placed on the back of the table tennis table top plate (1) in advance, and the magnetic member of the hanging hanger (10) and the magnet are used to hold the hanging hanger (10). Attach and detach the hanger (10).

A cushioning material is used on the inner bottom of the falling ball collection box (12) to dampen the elasticity when the ball falls, preventing the ball from jumping out of the falling ball collection box (12), and the cushioning material has a slope in the left and right direction. By providing this, it is possible to guide the balls to gather in the direction of the batter.

According to the present invention, balls that hit the net during table tennis practice or some of the balls that fly out of the table tennis table around the net can be caught by the falling ball collection box (12), thereby reducing the number of balls falling onto the floor. This reduces the effort and time required to pick up fallen balls, allowing for more efficient practice.
