ABSTRACT:
A method for raising, by an individual, a unitized foldable tent framework which has a perimetric interconnection of roof members that is formed to permit expansion and contraction of separation between lower ends of adjacent roof members, the perimetric interconnection being concentrically enclosed by sectioned tubular eave members. The raising is accomplished by placing the folded tent frame in a vertical position; extending outwards the lower ends of wall members; raising the pivotally connected upper ends of the roof members, past a location where the roof members are coplanar, to a proximate raised position; temporarily retaining the tent framework in that position by the perimetric interconnection; connecting the sectioned eave members between adjacent roof members, and, finally, locking the pivotal connection between roof, wall, and eave members. The pivotal connection of the roof, wall, and eave members may be provided by a hub member, attached to the roof, wall, and eave members, and a hub lock member which, by rotation relative to the hub member, locks the roof, wall, and eave members into a fixed position, so that the locking step may be accomplished by rotating the hub lock member relative to the hub member. Where the roof, wall, and eave members are resilient, an additional step prior to locking may include applying external inward pressure on the hub member until the roof, wall, and eave members are substantially coplanar.
