願昭62−078628で開示）（考案が解決しようとする課題）これは、次のような欠点があつた。(Prior Art) Conventionally, a rotary shaft/bar connector was attached to each board section instead of one. Also, the weight of the board was removable, and could be removed and replaced each time the board was set up or down. (Disclosed in Utility Model Application No. 62-078628) (Problems to be solved by the invention) This had the following drawbacks.

回転軸兼バー接続器がボード部ごとに接続して
いたため、中央のバーが使用していくうちに重さ
のため下がつてしまいバーが平行を保てなくなつ
てしまう。また、ボードの重りが着脱式なため、
使用中にはずみではずれてしまう。 Since the rotating shaft/bar connector was connected to each board section, the center bar would sag due to its weight as it was used, making it impossible to keep the bars parallel. In addition, since the weight of the board is removable,
It comes off due to force during use.

本考案は、これらの欠点を除くためになされた
ものである。 The present invention has been made to eliminate these drawbacks.

る様にした。(Means for Solving the Problems) In order to solve the above problems, the present invention provides a hurdle with a board in which a bar 1, a board 3, and a weight 4 of the board 3 are attached to a rotating shaft/bar connector 2.
The rotating shaft/bar connector 2 is made into one, and the bars 1 and boards 3 are attached alternately to this rotating shaft/bar connector 2, and the board 3 can be rotated 360 degrees to the rotating shaft together with the weight 4 using the adjustment screw 5. Attached to the board, Board 3 can be stood up or folded down. Also, center the board 3 around the adjustment screw 5 or the rotating shaft/bar connector 2.
By rotating it 180 degrees, it can be folded approximately parallel to the weight 4 side. As another example, in a hurdle with a board in which a bar 1 and a board 3 are attached to a rotating shaft/bar connector 2, the board 3 is attached to the bar 1 with a hinge-shaped connecting fitting 9 with a spring 10 attached, and the repulsive force of the spring 10 is used. The board 3 is always in a standing state, and the spring 10 is made detachable or loosenable.

Return to When using it as a normal hurdle, adjust screw 5.
Loosen the , rotate board 3 180 degrees along the rotation axis, and then fold board 3 to use it.

（実施例）以下、本考案の実施例について説明する。(Example) Examples of the present invention will be described below.

また重りもゴム板や樹脂板のように当たつてもい
たくないものが良い。 On the opposite side of the bar from which the hurdler is running, place one rotating shaft and bar connector so that the bar 1 and the board 3 are alternated like this: bar 1, board 3, bar 1, board 3, bar 1. Attach 2. In addition, a rotating metal fitting/bar/weight connector 6 is attached to the rotating shaft/bar connector 2, a plate-shaped weight 4 is fixed thereto with screws, and a board 3 is attached parallel to the weight 4 using an adjustment screw 5.
Attach the board 3 and weight 4 together on the rotating shaft.
Installed so that it can rotate 360 degrees. When the board 3 is set up as shown in Figure 1, the board 3 should protrude from the top of the bar 1, and when the board 3 is folded down, the weight 4 should not protrude above the top of the bar 1 as shown in Figure 3. Make it. Board 3 should be made of plastic, hard rubber, resin, or other material that will not break even if the hurdle falls.
It is also best to use a weight that you do not want to hit, such as a rubber plate or a resin plate.

方法でも良い。 In addition, as a method of standing up or laying down the board 3, as shown in FIGS.
In addition to the method of rotating the board 3 180 degrees and folding it so that it overlaps almost parallel to the weight 4 side, as shown in Figs. 4 and 5, the weight 4 can be attached to the board 3 in a hinge shape, The board 3 is configured to be able to rotate 180 degrees along the rotation axis 2 around the adjustment screw 5, and by loosening the adjustment screw 5 and rotating around the rotation axis 2, the board 3 is overlapped with the weight 4 side. It is also possible to fold it in different ways.

バネ１０を緩める方法でも良い。 In addition to the above-mentioned method, as a hurdle with a board for hurdling practice, the board 3 and the bar 1 are connected by a hinge-shaped connecting fitting 9 with a spring 10, as shown in another embodiment of FIG. It is also possible to make board 3 stand up using the repulsion force of 1. At this time, the method of folding the board 3 may be a method of removing the spring 10 or a method of loosening the spring 10.

用中はずれたり無くなつたりしなくなる。(Effects of the invention) Since there is only one rotating shaft/bar connector 2, installation is easier, and the center part of the bar does not come down or the connection part tilts, making it difficult for the board to rotate. Furthermore, there is no need to remove the weight, so it will not come off or get lost during use.
