The corner hubs (18) have two tubular members (50) which join forming a first obtuse angle (32), where a structural web (56) may be provided to help maintain the first obtuse angle (32) and strengthen the corner hub (18). Similarly the roof hubs (20) have tubular members (60) which form second obtuse angles (34) between any pair of the tubular members (60). The roof hubs (20) may include a series of webs (66) which act to maintain the angular relationships of the tubular members (60), including the second obtuse angles (34). Only larger embodiments of the tent pole system (10) require the use of ridge poles (40).Other References
