Abstract

An adjustable safety net assembly includes a netting panel capable of spanning a first area, and net adjusters which reconfigure the netting panel for purposes of spanning a second, relatively smaller area.

Claims

1. An adjustable safety net assembly, comprising:

a mesh panel of flexible elongate members which cooperate to form a matrix of intersections and openings bounded by a perimeter of preestablished dimensions; and

a plurality of spaced net adjusters engaged with said mesh panel proximate said perimeter, wherein each of said net adjusters includes a flexible strap and a strap retainer which cooperate to selectively form a snug closed loop about an edge of said mesh panel and a select one of said intersections disposed inward from said edge, thereby effectively reducing at least one of said preestablished dimensions, wherein each said strap has a first end portion, a second end portion, and a closed loop portion disposed therebetween, and said first end portion is inserted through said closed loop portion in a manner which captures an edge of said mesh panel therebetween, and each said strap retainer is a buckle connected to said first end portion of a respective strap.

2. The adjustable safety net assembly of claim 1, wherein said net adjusters are disposed along two adjacent edges of said mesh panel which extend perpendicular to one another.

3. An adjustable safety net assembly, comprising:

a mesh panel of flexible elongate members which cooperate to form a matrix of intersections and openings bounded by a perimeter of preestablished dimensions;

a flexible border rove connected to said panel at said perimeter; and

a plurality of spaced net adjusters engaged with said border rope at said perimeter, wherein each of said net adjusters includes at least one flexible strap and at least one strap retainer which cooperate with the border rope to selectively gather a portion of said mesh panel into an inactive state between opposite portions of said border rope and thereby impose a reduced net span between said opposite portions of said border rope, wherein said net adjusters are disposed along a first segment of said border rope, and each of said net adjusters selectively forms a snug closed loop about said first segment of said border rope and more than one of said intersections.

4. The safety net assembly of claim 3, wherein each of said net adjusters is connected to said border rope independent of said snug closed loop.

5. A safety net assembly, comprising:

a safety net including a mesh panel and a border rope, wherein said mesh panel has a perimeter and said border rope is secured to said mesh panel about said perimeter; and

means, connected to said safety net, for selectively transforming said safety net between a first configuration sized and configured to span a first flat area having a first width and a first length, measured perpendicular to one another, and a second configuration sized and configured to span only a relatively smaller, second flat area having a second width and a relatively smaller, second length, measured perpendicular to one another, wherein said means is operable to transform said safety net without disassembling any portion of said safety net, and when said safety net is transformed into said second configuration, said means is interconnected between said border rope and an interior portion of said safety net.

6. The safety net assembly of claim 5, further comprising another means, connected to said safety net, for transforming said safety net into a third configuration sized and configured to span only a relatively smaller, third flat area having a relatively smaller, third width and a length equal to the second, relatively smaller length, wherein said another means is operable to transform said safety net without disassembling any portion of said safety net.

7. The safety net of claim 5, wherein said means includes a plurality of flexible straps connected to said border rope.

8. The safety net of claim 5, wherein said means selectively forms a first closed loop about said border rope, and said means selectively forms a second closed loop about an interior portion of said mesh panel.

9. The safety net of claim 5, wherein said means forms a closed loop about said border rope when safety net is in said first configuration, and said means forms a closed loop about both said border rope and an interior portion of said mesh panel when said safety net is in said second configuration.

10. A safety net assembly, comprising:

a safety net including a mesh panel and a border rope, wherein said mesh panel has a perimeter and said border rope is secured to said mesh panel about said perimeter; and

means, connected to said safety net, for selectively transforming said safety net between a first configuration sized and configured to span a first flat area having a first width and a first length, measured perpendicular to one another, and a second configuration sized and configured to span only a relatively smaller, second flat area having a second width and a relatively smaller, second length, measured perpendicular to one another, wherein said means is operable to transform said safety net without disassembling any portion of said safety net, wherein said means forms a closed loop about said border rope when safety net is in said first configuration, and said means forms a closed loop about both said border rope and an interior portion of said mesh panel when said safety net is in said second configuration.

11. The safety net assembly of claim 10, further comprising another means, connected to said safety net, for transforming said safety net into a third configuration sized and configured to span only a relatively smaller, third flat area having a relatively smaller, third width and a length equal to the second, relatively smaller length, wherein said another means is operable to transform said safety net without disassembling any portion of said safety net.

12. The safety net of claim 10, wherein said means includes a plurality of flexible straps connected to said border rope.
