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.
Claims12
A shelter of the type which is portable and collapsible adapted for use on either a natural ground surface or a man-made surface comprising
- frame means for supporting said shelter when said shelter is fully erected
- cover means extending over said frame means and attached thereto for applying compressive forces to said frame means and for applying forces tending to collapse said frame means when fully extended
- brace means attached to said frame means for opposing said collapsing forces,
- wherein said frame means comprises a first substantially vertical, a last substantially horizontal, and at least one intermediate curved bow members, pivotally attached to their ends to a pair of spaced hub members forming a curved structure having substantially vertical sides, and said brace means includes a pair of oppositely disposed braces attached to said substantially vertical sides, said braces each comprising a first link pivotally attached at one end to said vertical bow and a second link attached at one end to said horizontal bow, the other ends of said links being pivotally attached to each other at their other ends by a connector having a headed stem extending therefrom, said intermediate bow having a keyhole slot formed therein with a larger round portion of said slot being disposed toward said hub member and an elongated portion of said slot extending away from said hub member, said headed stem being received within said keyhole slot and being positioned at the elongated portion of said slot when said structure is fully erected, said links forming an angle therebetween having the apex thereof extending away from said hub member.
A shelter of the type which is portable and collapsible adapted for use on either a natural ground surface or a man-made surface comprising
- frame means comprising a first bow, a second bow and at least one intermediate bow therebetween, a pair of spaced hubs, the ends of said bows being pivotally attached to said hubs
- cover means extending over said frame and attached thereto for applying compressive forces to said frame and for applying forces tending to collapse said frame when fully extended
- brace means comprising link members pivotally attached to said first and second bows and to each other, said links forming an angle therebetween having the apex thereof extending away from said hub
- means detachably connecting said links to said intermediate bow for extending said frame and for locking said links to said intermediate bow by the collapsing forces of said cover.
