Abstract
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.
Claims22
A safety net arrangement for multi-floor buildings under construction, comprising:
- (a) a safety net having opposite end regions;
- (b) a pair of movable support structures, each supporting a respective end region of the net, for supporting the net in a deployed condition in which the net extends generally outwardly away from an outer face of a building under construction over a predetermined distance;
- (c) a plurality of guides mounted on the building adjacent the outer face, for guiding the support structures for vertical movement along the outer face;
- and
- (d) a pair of manually-operated winches, each operatively connected to a respective support structure, for manually moving the support structures independently of each other and in alternate succession to different elevations while maintaining the net in the deployed condition during each movement, each winch having a handle located below the net in the deployed condition to enable an operator to operate the winch from a safe protected position in which the net shields the operator from injury.

A safety net arrangement for multifloor buildings under construction, comprising:
- (a) a safety net having opposite end regions;
- (b) support means for supporting the net in a deployed condition in which the net extends generally outwardly away from an outer face of a building under construction over a predetermined distance, said support means including a pair of support structures, each supporting a respective end region of the net;
- (c) means for vertically moving the support means and the net in the deployed condition along the outer building face;
- and
- (d) a curtain mounted on the support means and extending between the support structures above the net for joint movement therewith.

- (b) a pair of movable support structures, each supporting a respective end region of the net, for supporting the net in a deployed condition in which the net extends generally outwardly away from an outer face of a building under construction over a predetermined distance, each support structure including
- (i) an upright elongated support positioned adjacent the outer face,
- (ii) a cantilevered support pivotably mounted on the upright support, and extending generally outwardly therefrom away from the outer face, and
- (iii) a flexible cable strung between the supports and extending downwardly from the upright support to the cantilevered support;
- and
- (c) means for vertically moving the support structures and the net in the deployed condition along the outer face of the building.
