Description

ABSTRACT:
A collapsible free-standing frame structure includes N bowable resilient legs, where N is an integer greater than one, a multi-hinge, and a leg restraint. The multi-hinge includes a hinge body and N leg interconnectors for interconnecting the legs to the hinge body. The leg interconnectors are pivotally mounted to the hinge body for limited pivotal motion between closed positions, in which the interconnected legs are clustered around a central axis which extends through the hinge body, and open positions, in which the interconnected legs extend radially relative to the central axis. A pivot stop prevents the leg interconnectors from pivoting beyond the open positions. To erect the frame structure, the leg interconnectors are pivoted to their open positions, the interconnected legs are bowed against the pivot stop, and the distal ends of the bowed legs are attached to a leg restraint which maintains the legs in the bowed position.
