loosening or shifting over time in use may be essentially permanently affixed to the other end of the lower circumferential support 42 whereas unless the roof struts 22 a e are constructed to enable e g telescoping the anchor ring 130 on the upper circumferential support may need to be undone each time to enable the roof struts 22 a e to extend toward an apex position from the storage collapsed position due to their rigid length and the circumference of the upper circumferential support 40 in its tightened position as shown in fig8 the sections 12 a b c d and e are laid out with the anchor rings tight against the apexes 82 a a nd 80 a respectively and with the upper and lower horixontal flexible circumferential support cable or ropes 40 and 42 extending out of one half of the apex 82 e and out of the apex 80 e and through upper collapsible structural support member 30 e turning now to fig9 there is shown the initial stage of folding the collapsible horizontal support members between the respective adjacent vertical poles the roof posts 22 a b c de and e are then folded downwardly to the inside of the collapsed structure as shown in fig1 a with the lower horizontal flexible support member 42 pulled to tighten the bundle and with the portion of the upper horizontal flexible support structure wrapped around the upper portion of the collapsed bundle to further tighten the collapsed bundle prior to insertion of the bundle into the storage bag as shown in fig1 b it will be understood that the folding operation discussed in this paragraph can occur both with the apex.
