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.
Claims8
A scaffold structure for placement on an upright wall element, comprising:
- first and second horizontal members adapted to support a horizontal work platform rested on the upper surfaces thereof;
- said first horizontal member having opposed inner and outer ends;
- means fixed to the inner end of the first horizontal member for securing it to an upright wall element at an above-ground elevation;
- said second horizontal member having opposed inner and outer ends, the inner end of the second horizontal member being telescopically supported on the outer end of said first horizontal member coaxial adjustment relative thereto;
- means for fixing said second horizontal member to said first horizontal member;
- a bracket fixed to the inner end of said second horizontal member;
- said bracket being open downwardly as well as vertically along a direction facing the first horizontal member;
- and upright support means affixed to said bracket and extending downward perpendicular to said horizontal members or downward at an angle inclined to a fixed reference, whereby the first and second horizontal members are elevationally supported intermediate their combined lengths.
