Summary:PROBLEM TO BE SOLVED: To enable one worker to change the height of bars in the uneven parallel bars.SOLUTION: The left and right supports of the parallel bars are double pipe structure composed of an outer pipe 6 and an inner pipe 7. As a height adjustment mechanism, the left and right supports have a height adjustment plate 21 attached to the outer pipe 6 and a rod-like stopper member 31 held on the inner pipe 7. The height adjustment plate 21 includes a slit 27 in which a large diameter shank 32b of a shaft member 32 is vertically slidable and a plurality of engaging holes 28 which are superimposed on the slit 27. The stopper member 31 is always energized in a receding direction with a coil spring 37 so that the stopper part 34 is fitted to the engaging holes 28. A worker can change the height by holding a grip part 36 to draw out the stopper member 31 and by vertically shifting it.SELECTED DRAWING: Figure 5 【課題】段違い平行棒の高バーの高さ変更を１人の作業者で行えるようにする。【解決手段】高バーの左右の支柱は、外管６と内管７との二重管構造をなす。高さ調整機構として、外管６に取り付けた高さ調整プレート２１と、内管７に支持された棒状のストッパ部材３１と、を有する。高さ調整プレート２１は、軸部材３２の大径軸部３２ｂが上下にスライド可能なスリット２７と、スリット２７と重なった複数個の係止孔２８と、を有する。ストッパ部材３１は、ストッパ部３４が係止孔２８に嵌合するように、コイルスプリング３７によって後退方向に常に付勢されている。作業者は、グリップ部３６を把持してストッパ部材３１を引き出し、上下に移動させることで、高さ変更が可能である。【選択図】図５
