ABSTRACT:
A scaffold has a rigid main frame with cross members secured to each other to prevent all pivoting and angular movement of the members relative to each other and end frames pivotally mounted on the main frame with sleeves for movements between folded positions adjacent opposite sides of the main frame and open positions generally normal to the main frame. Releasable locks retain the end frames in the open positions. Supports for a person and objects extend between and are mounted on the end frames when the end frames are in the open positions.
