次に本考案の実施例を示す図面につき、構成、作用並び
に効果につき説明する。Next, the configuration, operation, and effects will be explained with reference to the drawings showing the embodiments of the present invention.

１は平板、２，２は連結具で、筒体３内にスプリング４
を内装して、後方に先端を平板１の上方両側縁部に取付

に先端が鉄棒Ａに廻動可能に締結具６′にて嵌着する嵌
着金具６を各連結する。1 is a flat plate, 2 and 2 are connectors, and a spring 4 is installed inside the cylinder 3.
a connecting rod 5 whose tips are rotatably pivoted to the upper side edges of the flat plate 1 at the rear with fittings 5', and a fastener 6 whose tips are rotatably connected to the iron rod A at the front. The fitting fittings 6 to be fitted are connected at ''.

７．７は固定盤で、上記平板１の下端両側縁に軸芯７′
で枢着し、使用時には上面に穿設の貫通孔を通して地中
Ｂに杭釘８を打込んで固定する。7.7 is a fixed plate, and the shaft center 7' is attached to both sides of the lower end of the flat plate 1.
When in use, a stake nail 8 is driven into the ground B through a through hole drilled in the upper surface to fix it.

斯くして、平板１は、上方は連結具２によってスプリン
グ４を介して鉄棒Ａに連結し、下方は、鉄棒Ａの真下附
近の地面に固定盤７によって固定し、上下各廻動可能に
、傾斜状態に取付けられる。In this way, the flat plate 1 is connected at the upper part to the iron rod A via the spring 4 by the connector 2, and at the lower part is fixed to the ground directly below the iron rod A by the fixed plate 7, so that it can be rotated up and down. Mounted in a tilted position.

本考案は、上記の如き構成であり、練習時には児童は、
両腕にて鉄棒に吊下り、両脚を前進させて平板１の傾斜
面を登りながら次第に逆さ状になり、適所において両足
或は片足にて、平板面１を強く踏つける。The present invention has the above-mentioned structure, and during practice, the children
The user is suspended from a horizontal bar by both arms, moves forward with both legs, climbs the slope of the flat plate 1, gradually becomes upside down, and strongly steps on the flat plate surface 1 with both feet or one foot at the appropriate position.

このとき平板１の上面はやや後退し、踏つけ力は連結具
２に伝り、スプリング４は圧縮され、連結具２は伸張す
るが、瞬時にスプリング４の弾力による復元力により、
踏み足はその反動をうけ上方に押上げられることになり
、腕力とによって児童の腰が、鉄棒の廻りを回転して容
易に、逆下りができることになる。At this time, the upper surface of the flat plate 1 recedes slightly, the stepping force is transmitted to the connector 2, the spring 4 is compressed, and the connector 2 is expanded, but instantaneously, due to the restoring force due to the elasticity of the spring 4,
The stepping foot is pushed upward by the reaction, and the child's waist rotates around the horizontal bar due to the strength of the child's arms, allowing him or her to easily descend backwards.

本考案は、平板１は、両側上端部を連結具２，２で鉄棒
Ａに吊掛式に連結し、下方は固定盤６，６で地面に固定
するので、その取付けが非常に安定し、固定盤７の地面
の固定位置によって、上方の連結具２は、両端連結部が
取付具５′および嵌着金具６によって自由に廻動して揺

雑な伸縮調節機構等を必要とせず、従って構造的に簡単
で、全体的に軽量であり、教師の指導のもとに児童たち
の手で安全に運搬、取付けができるものである。In the present invention, the upper ends of the flat plate 1 are connected to the iron bar A by connecting devices 2, 2 in a hanging manner, and the lower part is fixed to the ground by the fixed plates 6, 6, so that the installation is very stable. Depending on the fixed position of the fixed platen 7 on the ground, the connecting parts at both ends of the upper connecting tool 2 can freely rotate and swing by the mounting tool 5' and the fitting fitting 6, and the hanging angle of the flat plate 1 changes. Since the inclination mounting can be adjusted, there is no need for the underframe for fixing the stationary platen 7 or the connecting rod 5 to have a complicated telescoping adjustment mechanism, etc. Therefore, it is structurally simple, lightweight overall, and easy to use for teachers. It can be safely transported and installed by children under the guidance of teachers.

又平板１が連結具２によって鉄棒Ａに吊掛状態になって
いるので、平板１に対する踏付力が、連結具２に引張力
として働き、鉄棒Ａのまわりに自由に揺動して、踏付力
が連結具２の軸心方向に作用することになり、内装のス
プリング４によって衝撃が無理なく緩和されるもので、
その作用効果が安定し、変則踏付位置による踏台の横倒
しや、位置変動が生ずることがなく、使用による危険性
は殆んどない。In addition, since the flat plate 1 is suspended from the iron bar A by the connector 2, the stepping force on the flat plate 1 acts as a tensile force on the connector 2, which swings freely around the iron bar A and is stepped on. The biasing force acts in the axial direction of the connector 2, and the impact is moderately alleviated by the internal spring 4.
The operation and effect are stable, the step does not fall sideways or its position changes due to irregular stepping positions, and there is almost no danger in its use.

本考案は上述の如く、従来の低鉄棒に取付けが簡単で、
児童が安全に、楽しく逆上りの練習ができ、実用上の効
果大である。As mentioned above, this invention is easy to install on conventional low iron bars.
Children can safely and happily practice reverse climbing, which has great practical effects.
