Description

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

In the past, table tennis competitions were usually played using hardballs, but in recent years, softball-style table tennis competitions have also begun to be held. However, between hard and soft balls,
There is a difference in the height of the nets spread over the table, with the height of the nets being stretched over the table 2 times higher for soft balls than for hard balls.
The current rule is to increase the height by cm.

Therefore, the object of the present invention is to provide a netting fitting that can easily and reliably adjust the height of the support post in response to such competitions involving both hard and soft balls.

The structure and operation of the present invention will be explained based on the drawings.

Reference numeral 1 denotes a base mounting bracket that is attached and fixed to the base plate a by any means, and 2 represents a support that is pivotally attached to the left and right side pieces 1' of the outer end of the base mounting bracket 1, and the support supports stand vertically as shown in the figure. At the same time, the base mounting bracket 1 is attached from the outside.
It can be rotated and stored on the back side. 3, 3 are adjustment holes provided on both left and right sides of the base end of this support 2,
This adjustment hole has stop holes 3' and 3'' for the support shaft 4, which will be described later, at its lower and upper limits, respectively, and the centers of these upper and lower stop holes are on a line in the vertical direction of the support column 2. In the case of the modified L-shaped adjustment hole 3 shown in FIG. 1 and the U-shaped adjustment hole 3 shown in FIG. The upper and lower stop holes are connected by a groove that is aligned in the vertical direction of the net and is offset in the direction in which the net is stretched. Reference numeral 4 denotes a support shaft inserted between the adjustment holes 3 and 3 on the left and right sides, and this support shaft is installed between the left and right pieces 1' of the outer end of the table mounting bracket 1. Reference numeral 5 denotes a cap provided at the tip of the pillar 2, on which the tension string of the net is hung.

For softballs, the net must be placed higher, so by tilting the support 2 slightly backwards and pulling it upward, the left and right adjustment holes 3, 3 provided at the base end of the support 2 are pushed upwards. is its upper limit stop hole 3″,
Since the support shaft 4 is moved to the guide from 3", the support shaft 4
are stopped and fixed in the lower limit stop holes 3', 3' of the adjustment holes 3, 3 (see Figs. 1 and 6). Therefore,
All you have to do is spread the net in this state.

In addition, in the case of hard balls, the position of the net must be lowered, so by tilting the support column 2 slightly backward and pulling it down, the support shaft 4 is moved to the lower limit stop holes 3' and 3 of the adjustment holes 3 and 3. ', and is stopped and fixed in the upper limit stop holes 3'' and 3'' (see Figs. 3 to 5). Therefore, it is sufficient to spread the net in this state.

In this way, the present invention provides adjustment holes 3 on both the left and right sides of the base end of the support column 2 to be pivoted to the left and right side pieces 1' of the outer end of the base mounting bracket 1, and the adjustment holes have a lower limit and an upper limit. Stop holes 3' and 3'' for the support shafts described below are provided respectively in the support shafts, and the centers of the upper and lower stop holes are on a line in the vertical direction of the support 2, and the upper and lower stop holes are grooves that are offset in the direction in which the net is stretched. The height of the support 2 is adjusted by inserting a support shaft 4 installed between the right and left sides of the outer end of the base mounting bracket 1 into the adjustment hole 3, and pivotally attaching the support 2. Because of this feature, it is possible to easily and reliably change the height position of the net depending on the soft and hard type of table tennis using one metal fitting, making it extremely easy to use. Its practical effects are great as it is rational and convenient.
