Abstract: In various representative aspects, a netting structure is configured to serve as a safety net used on construction sites to catch debris or construction personnel from falling to the ground. The netting structure eliminates the need to use a metal cable along the perimeter of a beam to support the net that typically requires the net to be clipped to the cable in several locations along its perimeter. An assembly for guiding the ropes used to pull the netting structure in place and secure the netting structure to a building frame is also provided.

Abstract: A flexible member used as a rope in a mesh has an outer sheathing which is easy to touch and an inner core which is shrinkable so that when used in a mesh which is suspended on a frame, it pulls the frame tautly by the shrinkage of the inner cords. Also, a connection between a support member and a border can be effected using one way mechanical fasteners. Shrink nets can be further used on a frame without sheathing with a twisted cord.

Abstract: A free standing perimeter net system is disclosed. The perimeter net system is comprised of a support arm, a support cable, an uplift brace, at least one net system brace, a back plate, a pivot, a vertical support, a strut, and a pair of strut brackets. These components work together to allow a safety net system to easily be installed around a structure without directly attaching to the structure. The support arm rotates between an open and a closed position on the pivot. This configuration allows the net, which is attached to the support arm, to be deployed at various angles. When the support arm rotates, the uplift brace also adjusts and aids in securing the support arm and net in the desired position. The vertical support couples the net system to the building or structure via the back plate and strut. The net system braces are also attached to the vertical support and provide added rigidity to the net system.

The net system comprises multiple large nets that are coupled to the ends of the cantilever arms with fasteners. The large nets are connected to each other with fasteners such as hooks, loops, wire, or rope and form a continuous protective barrier around the building.

Abstract: The invention resides in a system and method of tensioning a net comprising a frame having at least two opposing frame members and a net extending therebetween. The net is made from material of cords of a water soluble yarn capable of high shrinkage rates when wetted with water and dried. A tensioning device may be provided along one of said frame sides for causing tensioning of localized regions in said mesh after said mesh is wetted with water. The invention further resides in a method of tensioning a net to a frame having at least two opposing frame members and the net extending therebetween such that by sizing the net larger than said frame and mounting the net onto the frame such that the border is located outside of the frame and wetting the net and allowing it to dry, the net shrinks around the frame taking up play otherwise existing prior to the wetting step.

Abstract: A method for using a shrinking net system to protect people from falling objects on the premises of a building undergoing construction or renovations is described. The shrinking net system is easy to install and tension. The shrinking net system includes a shrinking net and a means to attach the net to a building. An object with the potential of falling is wrapped in the shrinking net. After the shrinking net is wrapped around the hazardous object, a rope or metal rod is woven through the net and securely attached to the building. The net is then wetted and shrinks to tightly fit around the dangerous object. Because the net is made from a material that shrinks when wetted, it will not become loose around the object over time. Among other things, the shrinking net system allows construction crews and the public to be on the premises of a building under construction or renovations without being at risk for injury from falling objects.
