ABSTRACT:
A portable and collapsible shelter is provided which includes a plurality of bows attached to a pair of spaced hubs. The bows are made up of three interlocking pieces which are held together by the tautness of the covering of the shelter. The shelter is prevented from collapsing by the inherent collapsing forces of the shelter in conjunction with side braces pinned together and locked, by the collapsing forces, within a keyhole slot formed in the center bow. A unique anchoring system comprising an anchor, which also serves as a digging tool and a tie rod, is used to anchor the shelter.
