Foldable enclosure members joined by hinged perimeter sections

Foldable enclosure members for a building structure, comprising:

• (a) a first planar laminate having a first generally linear edge;
• (b) a second planar laminate having a second generally linear edge;
• the first and second planar laminates each comprising a first facing layer;
• a layer of foam having a first face and a second opposing face;
• and a second facing layer;
• the first facing layer fastened to the first face of the layer of foam, and the second facing layer fastened to the second opposing face of the layer of foam;
• (c) a perimeter structure comprising:
• (1) a first perimeter section comprising a first elongate web surface having first and second elongate edge regions, the first perimeter section secured to the first generally linear edge of the first planar laminate and having a first series of hinge knuckles in proximity to the first elongate edge region and a second series of hinge knuckles in proximity to the second elongate edge region;
• (2) a second perimeter section comprising a second elongate web surface having third and fourth elongate edge regions, the second perimeter section secured to the second generally linear edge of the second planar laminate and having a third series of hinge knuckles in proximity to the third elongate edge region and a fourth series of hinge knuckles in proximity to the fourth elongate edge region;
• (d) the first series of hinge knuckles being intermeshed with the third series of hinge knuckles;
• (e) a first rod received in and joining the intermeshed first and third series of hinge knuckles to form a pivotable junction between the first perimeter section and the second perimeter section that can pivot from a folded position, where the first elongate web surface is oriented at an angle to the second elongate web surface, to an unfolded position where the first elongate web surface is in flush contact with the second elongate web surface;
• (f) the second series of hinge knuckles being adapted to intermesh with the fourth series of hinge knuckles when the pivotable junction is in the unfolded position;
• (g) a second rod;
• and
• (h) the second series of hinge knuckles and the fourth series of hinge knuckles being adapted to receive, when intermeshed, the second rod, to form a rigid structure between the first perimeter section and the second perimeter section, the rigid structure comprising the first perimeter section and the second perimeter section.
