Abstract: A quick assembly hinge mechanism for joining first and second panel members having top and bottom surfaces. The hinge mechanism comprises a first wing portion securable to a first edge of the first panel member, a second wing portion securable to a first edge of the second panel member, a pin member mounted to the first wing portion and a hook member mounted to the second wing portion. The pin member is generally parallel to the first edge of the first panel member when the first wing portion is secured thereto. When the second wing portion is secured to the second panel member, the opening of the bowl of the hook member directed generally downwardly toward the plane of the bottom surface of the second panel member.

Abstract: A composite construction panel comprises a core having an upper surface and a lower surface, a rigid upper cover sheet positioned above the upper surface, a rigid lower cover sheet positioned below the lower surface, and at least one conduit extending through the core having first and second ends terminating at one or more side edges of the core. The core is formed from an insulating material and includes rigid supporting members extending between and generally perpendicular to the upper surface and the lower surface. The upper and lower cover sheets are bonded to the supporting members to form a rigid composite panel. At least a portion of the core is removed adjacent at least a portion of the length of the conduit such that the lower and side portions of the conduit are adjacent to, and insulated by, the insulating material, but the upper portion is not insulated.
