Claims

[Claims for Utility Model Registration] 1. A frame base that is foldable via an appropriate link mechanism, and a platform for scaffolding that is attached to the frame base and is foldable in conjunction with the folding operation of the frame base. In a folding scaffolding device consisting of a board, the frame base has corner legs arranged at each of the four corners of the scaffolding top plate, and center legs arranged at each end of the folding center line of the scaffolding top plate. and a plurality of links whose base end is swingably attached to the center leg and whose distal end is swingably attached to the corner leg. The corner portions are swingably attached to the center legs via the folding connecting portions, and guide rails are arranged at the tips of the left and right split top plates in the respective corner portions in a predetermined direction. A guide roller that is movable along the guide rail is provided at the upper end of each leg, and when the frame base and the scaffolding top plate are in a folded state,
A folding scaffolding device characterized in that a guide roller is configured to move to a position close to a folding center line of a guide rail. 2 The meshing gear pieces are each fixed to the base end portion of the link that is swingably attached to the center leg, and the meshing gear piece is fixed to one link, and the meshing gear piece is fixed to the other link. 2. The folding scaffolding device according to claim 1, wherein the folding scaffolding devices are meshed with each other.
