发明名称 Jointly movable safety net and curtain arrangement for multi-floor buildings under construction
摘要 A worker operates a winch having a handle located below a fully deployed net from a protected position in which the net shields the worker from injury. A curtain is mounted either above or below the net on support structures therefor for joint movement with the net. A close-in bracket brings the inner edge of the net closer to an outer face of a building under construction.
