[Effect]

第２図は支柱杆１１で踏み板８を支持している
状態で、この支持状態から支持杆１１をスプリン
グ１３に抗して矢印方向に押し倒すと踏み板８は
枢着軸１８を支点にして第３図に示すように支柱
１，１間に倒すと係合溝６が係合杆７に係合して
踏み板８を倒伏即ち折り畳むことが出来る。 FIG. 2 shows a state in which the footboard 8 is supported by the support rod 11. From this supported state, when the support rod 11 is pushed down in the direction of the arrow against the spring 13, the footboard 8 is moved to the third position with the pivot shaft 18 as the fulcrum. As shown in the figure, when the footboard 8 is tilted down between the supports 1, 1, the engagement groove 6 engages the engagement rod 7, and the footboard 8 can be laid down or folded.

逆に踏み板８先端部を保持して係合溝９を係合
杆１０から外してやるとスプリング１３の復帰力
により支持杆１１が元の位置に戻されるから踏み
板８は起きて水平状態が支持される。 Conversely, if the tip of the tread plate 8 is held and the engagement groove 9 is removed from the engagement rod 10, the support rod 11 is returned to its original position by the restoring force of the spring 13, so the tread plate 8 is raised and supported in a horizontal state. Ru.

天板５の係合溝６を係合杆７から外すと前後の
支柱１，１，２，２を内側に折り畳む。 When the engagement groove 6 of the top plate 5 is removed from the engagement rod 7, the front and rear supports 1, 1, 2, 2 are folded inward.

〔Example〕

支柱１，１，２，２は鉄製角パイプを使用して
いる。 The pillars 1, 1, 2, and 2 are made of iron square pipes.

踏み板８の左右端裏側の長さ方向にガイド枠１
４を設け、このガイド枠１４の中に支持杆１１の
スライド枠１２を遊嵌している。 Guide frame 1 in the length direction on the back side of the left and right ends of the footboard 8
4, and the slide frame 12 of the support rod 11 is loosely fitted into this guide frame 14.

支柱１，１間、支柱２，２間に補強杆１６，１
７を架設し、この前後の補強杆１６，１７間にス
トツパー鎖１５を張設している。 Reinforcement rods 16, 1 between pillars 1 and 1 and between pillars 2 and 2
7 is constructed, and a stopper chain 15 is stretched between the reinforcing rods 16 and 17 on the front and rear sides.

[Effect of idea]

本考案は、上述の様に構成したから支持杆１１
をスプリング１３に抗して押し倒すだけで踏み板
８を折り畳むことが出来、逆に踏み板８の係合溝
９を係合杆１０から外すことにより踏み板８をひ
とりでに元の位置に戻し支持することが出来る。 Since the present invention is configured as described above, the support rod 11
The footboard 8 can be folded up by simply pushing down against the spring 13, and conversely, by removing the engagement groove 9 of the footboard 8 from the engagement rod 10, the footboard 8 can be automatically returned to its original position and supported. .

かように本考案は、踏み板８の起伏操作が容易
な折り畳み式踏み台を提供することになる等秀れ
た実用上の効果を有するものである。 As described above, the present invention has excellent practical effects such as providing a foldable step stool in which the step board 8 can be easily raised and lowered.
