The upper end portions of splayed legs are connected by pins that slide lengthwise of slots extending transversely of a crosspiece, the opposite ends of which can be supported by pairs of splayed legs, respectively. Sliding of the pins in their slots enables the ends of the legs to be fitted into sockets in the crosspiece and enables the legs to be withdrawn lengthwise from the crosspiece sockets, then swung together in substantial parallelism, and finally swung about the axis of the pins into overlapping folded relationship nested in angles of the crosspiece which is of T-bar cross section. Tubular extensions can be provided for the legs, and steps connecting the legs at opposite ends of the crosspiece can be attached for enabling a worker to step up onto the crosspiece.
