ABSTRACT:
A collapsible shelter includes an arcuate roof section which includes a left and a right edge having a downwardly extending lip portion. A plurality of left and right arcuate sections have a left edge provided with a downwardly extending lip portion and a right edge with an upwardly extending lip portion adapted to cooperate with downwardly extending lip portions of the arcuate roof section. The remaining left and right arcuate sections have a left edge provided with a downwardly extending lip portion and a right edge provided with an upwardly extending lip portion for cooperating with the downwardly extending lip portion of a previous left and right arcuate section. The base section has an arcuate extending base member and an upwardly extending lip adapted to cooperate with the downwardly extending lip portion of a left section. An arcuate door section has a door member portion that mates with the base member extending portion that may include locking means to prevent the dome shelter from collapsing. All of the arcuate sections terminate in end portions provided with an aperture proximate the distal ends thereof. A pair of bolts, one of which is placed through one of the apertures provided on the sections, locks the units together in a nesting manner and a second bolt locks the other apertures provided on the section members. Each of the sections nest within another section when the unit is completely extended and collapse to essentially the width of the roof section.
