The present disclosure provides a collapsible frame (12) for a shelter (10). The frame (12) includes a first leg (16), a second leg (18), and a foldable truss (24) coupling the first and second legs (16, 18). The truss (24) has first and second lateral members (46, 48) spaced relative to each other and pivotally coupled at first ends to the first leg (16) and extending laterally therefrom, at least one crosspiece (62) pivotally coupled between the first and the second spaced lateral members (46, 48), third and fourth lateral members (52, 54) spaced relative to each other and pivotally coupled at first ends to the second leg (18) and extending laterally therefrom, at least one crosspiece (64) pivotally coupled between the third and fourth spaced lateral members (52, 54), and a linkage (60) pivotally coupled second ends of the first and second lateral members (46, 48) and second ends of the third and the fourth lateral members (52, 54). The truss (24) is foldable at the linkage (60) between the first and the second legs (16, 18) to provide a collapsible frame (12). A frame according to the present disclosure has been found to provide exceptional strength when unfolded, while being easy to fold, and compact and easily transported when folded.
