Abstract
A portable shelter structure (10) of variable size consisting of an even number of individual, folding, modular units (12) which, in their folded condition, serve as shipping containers for the shelter. Rigid floor and rigid sidewall sections (22, 28) are hinged (24) along an adjacent edge allowing rotation of the sidewall section from a closed position to an upright position so that the sidewall is substantially perpendicular. Collapsible roof support beams (72) and flexible, collapsible roof covering units (14) are stored in a cavity created between the floor (22) and sidewall (28) sections when they are in their closed state. Collapsible end walls (16) having a door structure (17) therein can be stored in the modular unit cavity or in a separate vestibule packing unit (18) which attaches to the end wall as a separate closed space outside the end wall door.
