A collapsible, articulated structural section which is movable between a stable erect configuration and a collapsed configuration, said structure comprising:

• a first plurality of pivot means disposed to be spaced from each other and generally in a first plane in said erect configuration, and to be substantially adjacent each other in said collapsed configuration;
• a second plurality of pivot mean disposed to be spaced from each other and generally in a second plane in said erect configuration and to be substantially adjacent each other in said collapsed configuration;
• a plurality of pivotally interconnected side links for connecting said first plurality of pivot means with said second plurality of pivot means, each of said side links being connected with one of said first plurality of pivot means and one of said second plurality of pivot means;
• first and second face pivot means;
• and a first and a second plurality of face links, each of said first plurality of face links pivotally connected with said first face pivot means and with one of said first pivot means, and each of said second plurality of face links pivotally connected with said second face pivot means and with one of said second pivot means;
• each of said first plurality of face links crossing, but unconnected to, one of said second plurality of face links;
• and
• a first locking component associated with said first face pivot means, and a second locking component associated with said second face pivot means, said first and second locking components being adjacent each other in said stable condition and comprising means for holding said first and second face pivot means to each other in a position requiring manual release in order to allow said structural section to move from its stable, erect configuration to said collapsed configuration;
• and wherein said first locking component comprises means defining a through-extending opening in said first face pivot means, and wherein said second locking component comprises a central shaft extending from said second face pivot means towards said first face pivot means and having a free end on a portion thereof remote from said second face pivot means, said free end including a shaft terminating portion dimensioned to fit in said first face pivot means opening, and a rotatable locking member on the end of said shaft terminating portion, said rotatable locking member mounted to said shaft by means providing rotation thereof from a first position in-line with said shaft end termination so that it can pass through said first face pivot means opening, to a second position not in-line with said shaft end termination so that said locking member engages said first face pivot means on an opposite end thereof from said second face pivot means.

A collapsible, articulated structural section which is movable between a stable erect configuration and collapsed configuration, said structure comprising:

• a first plurality of pivot means;
• a second plurality of pivot means;
• a plurality of pivotally interconnected side links for interconnecting said first plurality of pivot means with said second plurality of pivot means, each of said side links being connected with one of said first plurality of pivot means and one of said second plurality of pivot means;
• first and second face pivot means;
• a first and a second plurality o face links, each of said first plurality of face links pivotally connected with said first face pivot means and with one of said first pivot means, and each of said second plurality of face links pivotally connected with said second face pivot means and with one of said second pivot means;
• each of said first plurality of face links crossing, but unconnected to, one of said second plurality of face links;
• a first locking component associated with said first face pivot means, and a second locking component associated with said second face pivot means;
• said first locking component comprising means defining a through-extending opening in said first face pivot means, and wherein said second locking component comprises a central shaft extending from said second face pivot means towards said first face pivot means and having a free end on a portion thereof remote from said second face pivot means, said free end including a shaft terminating portion dimensioned to fit in said first face pivot means opening and cooperable therewith to releasably hold said first and second face pivot means adjacent each other in said stable erect configuration.

• a second plurality of pivot means disposed to be spaced from each other and generally in a second plane in said erect configuration and to be substantially adjacent each other in said collapsed configuration;
• a plurality of pivotally interconnected side links for connecting said first plurality of pivot means with said second plurality of pivot means, each of said side links being connected with one of said first plurality of pivot means and one of said second plurality of pivot means;
• first and second face pivot means;
• and a first and a second plurality of face links, each of said first plurality of face links pivotally connected with said first face pivot means and with one of said first pivot means, and each of said second plurality of face links pivotally connected with said second face pivot means and with one of said second pivot means;
• each of said first plurality of face links crossing, but unconnected to one of said second plurality of face links;
• and first face pivot means being located closer to said second pivot means than it is to said first pivot means when said structural section is in said collapsed configuration;
• and
• a first locking component associated with said first face pivot means, and a second locking component associated with said second face pivot means, said first and second locking components comprising means, upon manual actuation, for holding said first and second face structural section in said stable erect configuration;
• and
• wherein said first and second face pivot means are concentric, and wherein said second plurality of face links are pivotally connected to said second face pivot means at points thereon further radially outwardly from said concentric center than the point of pivotal connection of said first plurality of face links to said first pivot means, so that during movement of said structural section between said erect and said collapsed configurations there is minimal, or no, frictional engagement between said first and second pluralities of face links.
