Abstract

A hinge is disclosed comprising one or more first hinge segments comprising a first surface having disposed thereon: a plurality of spatially separated first lugs each having a first slot formed therein; and a plurality of spatially separated first rods; one or more second hinge segments comprising a second surface having disposed thereon: a plurality of spatially separated second lugs, each second lug having a second slot formed therein; and a plurality of spatially separated second rods. The hinge has a first configuration of partial engagement of the first hinge segment with the second hinge segment where the first slots are aligned and engaged with the second rods; and a second configuration of full engagement of the first hinge segment and the second hinge segment wherein the first slots are rotatably engaged in a direction different than the first configuration.
