Carriage pin 506 extends through an aperture (not shown) formed in each of the tab members (not shown) of a panel 461 when the tab members are interdigitated. A straight sleeve-joint coupling 503 is configured similarly to angled-sleeve-joint coupling, but is straight rather than comprising an angle φ. A washer 507 is positioned and nut 508 is threaded onto carriage pin 505 in a well-known manner. While one carriage pin 506 is shown in FIG. 5B that extends between the top and bottom edges of a panel, it should be understood that a plurality of carriage pins could be used along the joining edges of adjacent panels 461.
  • FIG. 5C depicts an alternative configuration for coupling a spring 505 to recreational structure frame 450. One exemplary embodiment provides apertures 510 that are configured along a top side of frame 450 to accept the hook portion of a spring. An alternative embodiment provides apertures 510 arranged in an alternating manner along the top and bottom sides of a frame 450, such as disclosed by U.S. Pat. No. 7,396,318 B2 to VanElverdinghe to Adams and U.S. Patent Application Publication No. 2006/0258510 A1 to McGee et al., the disclosures of each being incorporated by reference herein. Another exemplary embodiment provides spring-attachment members 511 that are attached to a frame member 502 in a well-known manner, such as by welding. Spring-attachment members 511 are configured to accept the hook portion of a spring in the space formed between frame member 502 and the spring-attachment member 511.
  • FIG. 6 depicts a perspective view of an exemplary embodiment of a recreational frame T-coupler 600 that is suitable for use with the safety enclosure and recreational structure frame depicted in FIG. 1. T-coupler 600 comprises a horizontal portion 601 that is capable of receiving horizontal frame members (not shown) of a recreational frame structure in a well-known manner, and a vertical portion 602 that is capable of receiving a leg member of the recreational frame structure in a well-known manner. T-coupler 600 further comprises side sleeves 603 and 604 that in one exemplary embodiment are arranged directly adjacent to each other. In another exemplary embodiment, sleeves 603 and 604 are arranged to have a spacing between each sleeve. Side sleeves 603 and 604 are capable of receiving an end of a flexible rod 101 (FIG. 1). In one exemplary embodiment, sleeves 603 and 604 each include an aperture that is capable of receiving a spring-locking mechanism form into the end of a flexible rod 101. In another exemplary embodiment, sleeves 603 and 604 do not comprise an aperture that is capable of receiving a spring-locking mechanism of a flexible rod. It should be understood that alternative embodiments of a T-coupler could be used in place of the exemplary embodiment of T-coupler 600 depicted in FIG. 6. For example, exemplary suitable T-couplers are disclosed in U.S. Utility patent application Ser. No. 12/176,407, filed Jul. 20, 2008, entitled “Concentric Arrangement Frame Structure For Recreational Structure,” the disclosure of which is incorporated herein by reference. It should also be understood that vertical portion 602 of T-coupler 600 could have a length that is sufficient to be a leg of a trampoline structure.
  • Although the foregoing disclosed subject matter has been described in some detail for purposes of clarity of understanding, it will be apparent that certain changes and modifications may be practiced that are within the scope of the appended claims. Accordingly, the present embodiments are to be considered as illustrative and not restrictive, and the subject matter disclosed herein is not to be limited to the details given herein, but may be modified within the scope and equivalents of the appended claims.
