ている。2. Description of the Related Art Conventionally, on a workbench, as shown in FIG. 15, for example, a plurality of step bars 2 are attached at appropriate intervals between a pair of support legs 1 to form a ladder-shaped main leg 30. A rectangular top plate 32 is rotatably attached between the pair of main legs 30 of the
A bendable stay 31 is interposed between 32 and the main landing gear 30.

【０００３】そして、不使用時にはステイ31を折り曲げ

用できず、十分に活用されているとはいえない。Main legs 30 are provided on both sides of the top plate 32. Even though the main legs 30 are ladder-shaped, the top plate 32 is provided.
Since it is connected to the above, it cannot be used as a single ladder and can be used only as an integral part of the top plate 32, and cannot be said to be fully utilized.

After the scaffolding plate 7 is installed between the scaffolding plates 7 and the handrails 19 are attached, the workbench is assembled, and then the stepping bar 2 of the stepping workbench 5 with a handrail is used to go up to the footstep workbench 5 with a handrail, and the tread plate 6a. From here, move to the scaffolding plate 7 from here to work. in this case,
Since the handrail frame 8 or the handrail frame 9 is in a folded state in which the handrail frame 8 or the handrail frame 9 is rotated downward at the opening serving as the moving port to the scaffold plate 7 and is removed from the opening, the handrail frame 8 or the handrail frame 9 is not supported.
It does not hinder you from going up and down.

説明は省略する。In the first embodiment, the handrail 19 arranged between the stepped work platforms 5 with handrails has a two-stage structure of the upper bar 20 and the lower bar 21, but the present invention is not limited to this. Instead, as the second embodiment, a single-stage configuration can be used as shown in FIGS. 2 and 9 to 11. In this case, only the one used as the upper crosspiece 20 in the first embodiment is used. Since the structure is the same as the upper rail 20 of the first embodiment, detailed description thereof will be omitted here.
