A retractable safety barricade employed to block off an aisle or entryway, comprising a barricade housing that is mounted to a first support and a safety net attached at one end to a winding tube under spring tension located within the barricade housing and at the other to a pull bar, which may be secured to a second support. When the safety barricade is in its first position, the net is fully retracted onto the winding tube within the barricade housing by means of a coil spring. When the safety barricade is in its second position, the net is extended from housing to span the area between first and second supports, substantially covering the opening between the supports and blocking passage through the area. Operation of the device is performed by a single user, who manually extends or retracts the net barrier using the pull bar.

A safety net that includes at least one illuminating element. The safety net is intended to be stored in a rolled-up fashion (similar to a roll-up window shade) in the trunk of a vehicle. When illuminated, the safety net provides a completely new and unique means of alerting oncoming traffic to a road hazard or other situation requiring traffic control. The safety net provides a warning means that will not be knocked over by the wind, as wind blows freely through the voids of the net. In addition, the safety net screens the scene from the view of those in oncoming traffic. The device may include a solid state controller that provides a variety of patterns or symbols to further enhance the visual safety features of the device. This can be accomplished by placing fiber optic strands in the net voids, or within the side illuminating fiber optic conduit itself. The device may also include metal cables to form a physical barrier.

The illuminated safety net may use auxiliary light sources not requiring a power source attached thereabout the net as a secondary means to illuminate.

An elevator safety net system for preventing people, equipment, or debris from falling down commercial or residential elevator shafts during building construction, in each case avoiding injury. The net is a high-quality synthetic double-layer net with reinforced borders encased in fabric-sealed edges, and a plurality of steel grommets around the edges of the safety net. A plurality of safety nets may be suspended laterally up and down an elevator shaft before the elevator is installed, and this is done by screwing in eight eye bolts around the elevator shaft so that the safety net can be attached/suspended by snapping in closed steel hooks that connect the eye bolts to corresponding steel grommets of the net, thereby suspending the nets up and down the elevator shaft. The nets can be removed and reinstalled for future maintenance of the elevator shaft by snapping the hooks on and off the eye bolts screwed into the elevator shaft. Thus, if someone or something falls into the elevator shaft during post-construction maintenance, the net will be available to catch the person or thing without harm to themselves or others.

The invention relates to a lifting platform for protecting safety of high-level construction, which comprises an attached lifting scaffold working position system, a plurality of platform units for protecting the safety of the high-level construction and a supporting assembly.
