Description

[Detailed explanation of the idea] The present invention relates to a table tennis net support device.

Conventionally, this type of device has been known, such as Utility Model Publication No. 46-14167 and Utility Model Publication No. 51-13986. Even if it can be moved and fixed, the clamping interval must be adjusted in advance, so when adjusting the expansion or contraction of the spring with the adjustment nut, the other nut on the outside of this spring will also move accordingly. I needed to.

However, with this, there was no substantial difference in the number of handling steps compared to the previously known support that was screwed directly onto the lower surface of the base plate, and the mechanism became more complicated and the cost increased.

There was also a proposal such as Utility Model Publication No. 52-46196, but the mechanism was complicated.

Therefore, the object of the present invention is to provide a net support that has a mechanism that eliminates the drawbacks of the conventional products and is easy to handle, so that the support can be installed quickly and smoothly at all times.

The configuration of the present invention will be explained with reference to the embodiments shown in the drawings.

Reference numeral 1 denotes a frame body having a groove 2 formed in the central part in the longitudinal direction, and side plates 3, 3 are vertically formed on the left and right sides of the central part of this frame body.

Reference numeral 4 denotes a notch provided at one end of the frame 1, into which an open base end 7 of a columnar pipe 6 having a vertical groove 5 on the rear side is fitted, and the left and right sides thereof are inserted into the notch. are pivoted to the walls 8, 8 of the notch.

When the columnar pipe 6 is standing upright, a part of the front side of its base end is in the notch 4.
comes into contact with the front side of the

Reference numeral 10 denotes a bearing in which protrusions 11.11 are loosely attached to the left and right through holes of the base end 7 of the columnar pipe 6, and one end of the adjustment shaft 12 is fixed to this bearing in the longitudinal direction of the frame 1. I'm wearing it.

The position of the protrusion 11.11 of the bearing 10 moves as the columnar tube 6 rotates.

A rotation knob 13 is fixed to a part of this adjustment shaft 12.

Reference numeral 14 denotes a planar U-shaped guide having a long side plate installed on the back side of the frame 1, and the adjustment shaft 12 is inserted into the head 15 of this guide.

Reference numeral 16 denotes a support plate provided at a suitable location for this guide 14. A screw hole 17 is provided in the center of this support plate, into which a screw hole 18 formed on the rear side of the adjustment shaft 12 is screwed. match.

Reference numeral 19 denotes a bullet interposed on the adjustment shaft 12 between the head 15 of the guide 14 and the support plate 16; 20 a clamping member; the hanging parts 21 and 21 of this member are attached to the left and right sides of the guide 14; It is connected and pivoted to the side via a pin 22.

Cushion rubber 23 is fixed to the upper surface of the pinching member 20.

24 is a restraining plate fixed to the lower surface of the opening of the frame 1.

Next, the operation of the present invention will be explained.

When you want to stand the column tube 6 upright from the stored state as shown by the chain line in FIG. 2, hold the column tube 6 and turn it so that it stands vertically. The front surface of the frame 1 comes into contact with the front side of the notch 4 of the frame 1 and stops, but as the column tube 6 is shifted, the adjustment shaft 12 is also pulled.

When the adjustment shaft 12 is pulled by the column tube 6 and the column tube is in a horizontal state with the frame 1, the position of the protrusion 11.11 of the bearing 10 is the position where the adjustment shaft 12 is attached. The protrusion 11.11 is located below the pivot points 9 and 9 of the base end 7 of the frame 1, and if you continue to raise it, the protrusions 11 and 11 will move upward, and when it finally stands upright, it will be in the completely upper position. It's returning.

Therefore, the adjustment shaft 12 is slightly inclined and maintained under tension, and at the same time, the cushion rubber 23 of the clamping member 19, which moves upward, clamps the table tennis board from below.

The plate is held down from above by a holding plate 24.

The support of the present invention can be fixed by simply turning the column tube 6 upward from the bottom, but since there are differences in the thickness of table tennis boards, the holding plate 24
The opening degree of the clamping member 19 must be adjusted in advance.

To do this, when the knob 13 on the adjustment shaft 12 is rotated, the adjustment shaft 12 integrated therewith is rotated, and this is moved inward or outward via the screw 18 on the rear side. .

As a result, the length of the adjustment shaft 12 extending out from the head 15 of the guide 14 will vary slightly, and the arc length of the rotating column pipe 6 will also vary.

Therefore, there is a difference in the amount of upward movement of the pinching member 19,
There will be a difference in the degree of opening with respect to the upper restraining plate 24.

During use, since the net opening pulls the tension cord, the standing column pipe 6 will not fall backward.

At the end, after removing the tension string, if the column tube 6 is rotated backward, the adjustment shaft 12 will also move and the front clamping member 19 will be moved down, opening the table tennis board. It becomes free and comes off.

Since the present invention has such a structure and function, it is possible to easily turn the columnar pipe backward from below and make it stand upright, and it is also possible to securely maintain the upright state. It is possible to easily store the column in an inverted position by turning the column from the rear downward, and by simply turning the column, the table tennis board can be reliably sandwiched and the support can be attached. Depending on the thickness of the table tennis board, the distance between the clamping member and the holding plate for clamping and fixing the table tennis board should be adjusted accordingly.
Adjustment can be made in one way and reliably by simply turning the knob on the adjustment shaft, and the adjustment operation can always be done quickly and smoothly without any hassle.Therefore, the net support can be installed without removing it. Its practical effects are great, such as making the work extremely simple, and its simple structure allows it to be provided at a low cost.
