Folding scaffold
摘要:
An improved scaffold is proposed which can be easily assembled, and folded. It comprises a scaffold plate, a pair of ladders, hook members each secured to the scaffold plate, and holder members each pivotally mounted on the hook members. The hook members are adapted to receive one of the crossbars on the ladder and to support the holder members.
