ABSTRACT:
A scaffold structure for attachment to wall surfaces. Telescoping horizontal members are supported at an inner end by a secured wall bracket. The horizontal members are usable to carry a work platform resting on their upper surfaces. They are supported intermediate their ends by a depending bracket mounted to either a vertical post resting on a ground surface or an angular support extending upward from a lower wall bracket. Their outer ends include vertically open brackets for mounting vertical boards to serve as ground supports and/or handrail supports. A protective handrail can be mounted to the vertical boards at the outer ends of the horizontal members. An upright fixed adjacent to the outer end of each horizontal member is intersected by a roof member to provide an alternate form of outer support.
