Pinless hinge

Pivotally connected first and second panel assemblies, said first panel assembly comprising a panel and a first elongated component, sand said second panel assembly comprising a panel and a second elongated component;

• said first and second elongated components cooperating to form a hinge allowing relative pivotal movement between about 90 degrees and about 270 degrees of said first panel assembly with respect to said second panel assembly, without detachment;
• said first component comprising a first body, a generally straight first flange extending outwardly therefrom and terminating in a first distal end;
• a hooked termination of said first distal end, including an interior arcuate surface having a first radius extending between about 90 degrees and about 270 degrees, and an exterior projecting surface, said interior and exterior surfaces terminating in a common distal termination edge;
• and
• said second component comprising a second body, having:
• a second flange having a length, and extending outwardly therefrom and terminating in a second distal end, including an exterior arcuate surface having a second radius extending between about 90 degrees and about 270 degrees, and equal to or slightly less than said first radius and an interior opening of approximately the same size and shape as said common distal termination of said first distal end;
• and a third flange having a length and extending outwardly from said second body and having a side wall spaced a distance from said second flange throughout the majority of the length thereof approximately equal to the maximum dimension of said first flange exterior projecting surface from said first flange interior arcuate surface.

A two piece hinge consisting of first and second elongated cooperating components;

• surface means extending from said components for cooperating with each other so that said components are movable in controlled operative engagement with each other from a first position to a second position, one of said components moving through an arc of greater than about 180 degrees from said first position to said second position, without detachment;
• said surface means comprising means for cooperating so that said components are movable in controlled operative engagement with each other from said first to said second position, and so that said surface means define multiple different axes of rotation during relative movement of said components through said arc from said first position to said second position;
• wherein said surface means:
• define a first, stationary, axis of rotation during relative movement of said components through a first part of said arc;
• define a sliding axis of rotation through a second part of said arc;
• and define a third, stationary, axis of relation during relative movement of said components through a third part of said arc;
• and
• wherein said first part of said arc is roughly 35-45% of said arc, said second part is roughly 10-20% of said arc, and said third part is roughly 40-50% of said arc.
