The ends of each flexible rod 1501 are then coupled to frame 1550 by inserting each end into an aperture or a side-sleeve member, such as any of the apertures and/or side-sleeves described in connection with T-coupler devices disclosed herein, so that the rod 1501 forms an arch that spans between two apertures (and/or side-sleeve members) that are spaced apart. For example, referring to FIG. 15, a rod 1501 forms an arch that spans between two T-coupler devices 1551 located at point A and point C. Points A and C are spaced apart, in this case, by two times the length of the span of frame 1550 between two T-coupler devices 1551 plus the length of one T-coupler device 1551 that is located at B. Other exemplary distances are possible for forming an arch by a rod 1501.
The sleeve formed in flexible netting 1502 is coupled to an arched flexible rod at least at a top portion of the arch formed by a flexible rod. The arrangement is repeated around the frame 1550 so that adjacent flexible rods 1501 overlap and provide lateral support to each other. In one exemplary embodiment, the number of flexible rods 1501 equals the number of T-coupler devices in frame 1550 of the recreational structure. In another exemplary embodiment, the number of flexible rods 1501 is a sub-multiple of the number of number of T-coupler devices in frame 1550 of the recreational structure. While flexible rods 1501 are depicted in FIG. 15 has extending substantially vertically from frame 1550, the apertures and/or side-sleeve members that receive flexible rods 1501 could be oriented and the size of the top of the safety netting at the sleeves is such that flexible rods 1501 bow outward from frame 1550 before bowing back in at the top of the safety netting. Additionally, safety netting 1502 comprises a door arrangement (not shown) for allowing entry into the area enclosed by safety enclosure 1500.
In one exemplary embodiment, a flexible rod 1501 comprises a ferrule 1601 disposed at each end of the rod, such as shown in FIG. 16A. The size of ferrule 1601 is selected so that it can be inserted into an aperture or a sleeve-sleeve member of a T-coupler device. One exemplary embodiment of a ferrule 1601 comprises an integrated stop flange 1602 for preventing the flexible rod from being inserted too far into an aperture or a side-sleeve member of a T-coupler device. Further, in one exemplary embodiment, flexible rod 1501 can be formed from one piece. In an alternative exemplary embodiment, a flexible rod 1501 can be formed from a plurality of shorter flexible members 1501 a (FIGS. 16B and 16C). When flexible rod 1501 is formed from a plurality of flexible members 1501 a, the flexible members 1501 a can be fastened together using rigid connector ferrules, such as shown in FIGS. 16B and 16C. FIG. 16B shows one exemplary embodiment of a rigid connector ferrule 1602, and FIG. 16C shows an alternative exemplary embodiment of a rigid connector ferrule 1604. When flexible rod 1501 comprises a coated fiberglass rod, the jacket material of the fiberglass rod forming the coated portion should be removed if ferrule will be crimpled or glued.
