发明名称 Extendable scaffold bracket
摘要 A scaffold bracket for mounting on a ladder. The bracket comprises at least two legs, which are connected at one end to define a junction, said legs divergingly extending from the junction to their free ends. A plurality of first rung engaging members are distributed along the legs from their free ends and terminate short of the junction. A link is attached at the junction and terminates in a second rung engaging member. The bracket is so constructed and arranged that the legs are placed over a selected rung of the ladder and are engaged thereon by engagement of a first rung engaging member, the second rung engaging member is engaged over an upper located rung, a second bracket is similarly mounted on a second ladder placed side by side relative to the first ladder, and a wood plank is placed on the two brackets to constitute a scaffold.
