Claim 1
Independent Claim
211 words
An extendible shelter comprising: (a) a plurality of similar units each including floor, side wall and roof panels; (b) hinge members for connecting said side wall panels to previously assembled wall panels as units are added; (c) second hinge members for connecting a pair of wall panels to a pair of floor panels in the same unit; (d) a support beam for supporting said floor panels; (e) truss members connected to adjacent assembled wall panels; and (f) means for connecting said roof panels to said truss members; (g) flexible gaskets including open areas disposed within said gaskets to permit water drainage disposed around said panels and between adjacent panels when said shelter is assembled; (h) lateral support beams connected to adjustable jacks to permit leveling of said floor panels; (i) each said lateral support beams supporting floor panels of two adjacent units; (j) each of said units including a pair of floor panels extending outwardly from a pair of said side wall panels towards a center of said extendible shelter; (k) center support beams connected to adjustable jacks centrally disposed along said shelter to support a pair of floor panels in said units, and (l) locking mechanism including latches to lock said floor panels to said lateral and center support beams.
