Claims

[Scope of Claim for Utility Model Registration] (1) A leg attachment piece 5 is attached to a corner portion of the lower surface of a frame 1 which has a horizontally long rectangular shape in plan and has a working floor 2 stretched on its upper surface.
The upper end of the leg body 3, which is formed vertically by the upper pipe part 3a and the lower pipe part 3b and has casters 4 attached to the lower end, can be freely raised and lowered with respect to the leg attachment piece 5. The leg body 3 is configured to be located within the length of the leg attachment piece 5 when the leg body 3 is folded, and furthermore, the leg body 3 is configured to be located within the length of the leg attachment piece 5 when the frame body 1 is folded. The scaffolding stage is characterized in that a stacking stabilizing protrusion 7 is provided in a protruding manner so as to be able to engage with the leg attachment piece 5. (2) An engaging vertical groove hole forming metal fitting 9 is protruded from one end of the side end surface of the frame 1, and an engaging window hole 1 has a size large enough to receive the metal fitting 9 near the other end.
Further, an arcuate control hole 12 is formed in the upper surface of the frame 1 in a portion adjacent to the engagement window hole 10, and a pivot hole is formed in a position corresponding to the front edge of the control hole 12. A fastening hole 13 is formed, and a locking vertical rod part 11a and a supporting vertical rod part 11b are connected in parallel at each upper end with a predetermined interval maintained through a horizontal rod part 11c. The stopper 11,
The locking vertical rod portion 11a is connected to the arcuate control hole 12.
In addition, the support vertical rod portions 11b are inserted into the pivot holes 13 and attached so as to be movable up and down, and the locking fittings 11 are held in the retracted state on the support vertical rod portions 11b. A coil spring 14 is attached to the frame body 1.
Holes for attaching beam rods are provided at required corner portions for installing end beam rods 15 and intermediate beam rods 15a for supporting the scaffolding board 16 when configuring a large stage using a plurality of stages. 8. The scaffolding stage according to claim 1, further comprising a hole.
