Abstract
An erectable and transportable scaffold device adapted to be engaged on and supported on a support beam comprises front and rear frame structures which are pivotally interconnected by means of parallel side braces which are connected between the frame structures. A scaffold plate is pivotally connected to the lower ends of each of the front and rear frames. And the front frame is pivotal outwardly from the rear structure to form a cage within the front and rear structures and the side braces having a floor formed by a scaffold plate. The plate has upright bottom edges which fit flush against the insides of an angle member forming the sides of the front fra me structure so that it facilitates the holding of the structure in an erected cage forming position. A flexible or foldable member such as a chain or so is connected between the upper ends of each side of the front structure to the upper ends of each side of the rear structure. The rear structure also carries a rigid holding bracket rigidly connected to a bolt having a front pawl and a rear pawl which is slidable therealong and which may be engaged against a support structure such as an I-beam by threading a wing nut onto the bolt behind said year pawl to lock it in position.
