机译:梯子安全箍系统

摘要

A safety enclosure for a human worker positioned on a ladder, comprising a bracket connectable to first and second preselected rungs of a ladder, having a longitudinally extending central portion preselected in length to span at least two adjacent rungs of the ladder. A continuous open hoop-like member having a preselected opening sized so as to freely encompass the midsection of a human worker is connected to the bracket means adjacent the first preselected rung. The hoop-like member has a pair of side portions extending normal to the bracket, and a back portion connecting the two side portions. Auxiliary hoop means connects the outboard ends of the side portions to the bracket and adjacent to the second preselected ladder rung. The bracket includes a first U-shaped hook-like portion sized to hook over and longitudinally engage the first rung. The bracket also includes, at the other end thereof, a U-shaped portion sized to snugly and normally encompass said second preselected rung. The safety enclosure further includes stabilizer means attached to the side portions and having members which may be moved normal to the bracket toward and adjacent to a building wall against which the ladder is resting.
