Description

[Detailed Description of the Invention] The present invention relates to a net support for table tennis.

Originally, there were two types of table tennis: hard and soft, and the height of the net was different between hard and soft, so depending on whether the match is hard or soft, a dedicated net and net support are prepared and stretched for each game. I had to. According to the regulations of the Japan Table Tennis Association, hardball is
15.25cm, softball and Hopes (elementary school students and younger)
He is scheduled to compete at a net height of 17.25 cm.

The object of the present invention is to provide a net support that can be used for soft-ball games by simply inserting a small support into a hard-ball support.

Hereinafter, the present invention will be explained based on the drawings. It consists of a frame 1 that clamps the side edge of the table tennis table A, and a column 2 having a height for hardball competitions that can be raised up and down on the frame 1. A small support 3 having a height different from that for hard-ball games and soft-ball games is removably inserted into the upper end of the support 2 to extend the height of the support so that it can also be used for soft-ball games. It is composed of:

The frame 1 has a form and structure well known in this kind of technical field, and has a clamping tool a attached to the side edge of the table tennis table A at its tip, and a pivot b mounted on the side wall of the other end. The support column 2 is made to stand up and down freely. Note that the clamping tool a is not limited to the one shown in the drawings, and may have any shape.

The pillar 2 is formed into a roughly cylindrical shape with a height suitable for hardball competitions, and preferably has a roughly C-shaped cross section with a notch so that both ends of the net can be inserted into the cylinder along the pillar 2, and an opening. A folded piece 2' is formed on the part, an insertion groove RO is provided between the folded piece 2' and the support column 2, and an elongated guide hole c is bored in both side edges. The pivot shaft b is inserted through this guide hole c, and the support column 2
is held in a frame body 1 so as to be able to pivot up and down, and the support column 2 is housed within the frame body 1. That is, when the support column 2 is pulled out from the frame body 1 or inserted into the frame body 1, the guide hole c slides along the pivot axis b.

In addition, the pillar 2 is provided with protruding ridges d on the outer surface of the upper part of both side edges to prevent slipping when it is inserted into and taken out of the frame 1, and a groove e for the net tension string is formed on the back surface, and the upper end thereof A hook part is provided by cutting out f.

Incidentally, the shape of the support column 2 is not limited to the above shape, but any shape can be used as long as it stands upright at right angles to the frame body 1 and has a height that allows a rigid net to be stretched. Optional.

The small support 3 is formed at a height equal to the height difference between the height for hardball competitions and the height for softball competitions, and is formed into a cylindrical shape or approximately I-shape that is approximately the same as the support 2, and has anti-slip protrusions d on the outer surface of both sides. ' is provided protrudingly, and a concave groove e' for the net tension string is formed on the back surface, and a hook part is provided by cutting out the upper end of the groove e'.

Further, this small support 3 is provided with a step g at the lower end of both side edges, and fitting pieces h, h are provided to extend downward, and the fitting pieces h, h are inserted from the upper end of the support 2 into the inside of the support 2, that is, from the folded back. The small support 3 can be attached to the upper end of the support 2 by inserting it into the insertion groove formed by the piece 2'.

The small support 3 is detachably inserted into the upper end of the support 2, and the height of the support during insertion is set to a height that allows a net for soft-ball games to be stretched. For example, the shape is arbitrary and is not limited to the above shape.

Therefore, in the present invention, the upper end of a column that is erected on a frame that clamps the side edge of a table tennis table and has a height suitable for hard-ball games is formed at a height that is the difference between those for hard-ball games and soft-ball games. Since the small post is attached removably, it can be used in softball matches by simply setting up the net, and in hardball matches, it can be used by simply removing the small post from the top of the support. It is convenient and cost-effective, almost the same as conventional NetSupport, and its effects are extremely large.

Therefore, the intended purpose can be achieved.

[Scope of utility model registration request] The height of the small post is the same as the height difference between the height for hardball competitions and the height for softball competitions, and a fitting part is provided at the bottom, and a hook part for a net tension string is formed at the upper end. The upper end of the column, which is formed to a desired height and has a hooking part for the net tension string at the upper end, has an insertion part into which the fitting part of the small column can be detachably inserted. A net support for table tennis that can be adjusted to the height for softball competitions.
