Abstract
Abstract A plurality of arched rib supports is provided with each rib support being pivoted at the upper end or apex thereof so that the lower end portions may move towards one another. A flexible cover is secured to the rib supports and the lower ends are normally mounted upon a common locus so that the shelter can be opened in the form of a partial torus. When it is to be stored and/or transported, the rib supports are folded together to overlap one another, detached from the means pivoting same on a common locus and then the ends are moved towards one another so that they overlap with the gores of the flexible cover being between adjacent hoops. This reduces the overall size of the rib supports, and facilitates handling of the collapsed shelter.

Total Claims: 10
Claim 1
Independent Claim
217 words
A collapsible shelter comprising in combination two sets of arched rib supports, each of said supports including a pair of lower ends, means to mount said lower ends of each set on an individual substantially common axis for pivotal action of said arched rib supports from a collapsed folded position to an open erected position and vice-versa, a flexible cover secured to and extending over said rib supports, and a flexible substantially triangular gore extending between the adjacent inner ends of the flexible cover, each of said rib supports comprising at least two sections one each extending upwardly from one of said lower ends and being pivotally secured together at the apex of said arched rib support for hinging action whereby, when said rib supports are in the folded collapsed position, the lower ends may be folded inwardly towards one another and overlap one another together with said flexible cover, for storage purposes, said means to mount said lower end portions on a substantially common axis including a mounting channel and an end plate pivoted adjacent each end of said channel, transverse bolt means extending through said end plates and through the lower end portions of said rib supports whereby said rib supports are pivotally mounted upon said bolt means and fastening means for said bolt means.
