Abstract: A pop-up display apparatus. The apparatus includes a knuckle defining a pivot axis and having a pair of parts, the pair of parts being pivotally connected to one another for relative movement about the pivot axis. A base portion is connected to one of the pair of parts. The apparatus includes a leaf portion connected to the other of the pair of parts for pivotal movement relative to the base portion about the pivot axis and a tab portion movable relative to the leaf portion between a released position and an engaged position.

Abstract: A modular frame assembly is disclosed. The assembly includes a plurality of supports, and at least one connector for interconnecting the supports. The connector includes a base, a plurality of legs extending outwardly from the base, each leg defining a socket having an exterior surface that has a generally constant profile throughout the length of the leg, and a member that is movable between an engaged position in which it projects interiorly of the leg, and a disengaged position in which it is flush with the exterior surface, the member being biased to the disengaged position. Additional components, such as shelf supports, mounting brackets, shelf brackets, and risers, can be included in the assembly. The modular nature of the assembly allows for a wide arrangement of structures to be created.

Abstract: A composite includes a board. The board includes: a pair of corrugated layers, each corrugated layer being formed from two corrugated sheets bonded together; and a cardboard honeycomb disposed between and bonded to the corrugated layers, the honeycomb being orientated such that the cells extend between the corrugated layers. The board can be cut using conventional machinery without fraying [thereby requiring little or no sanding] and can be edgetaped without being crushed using conventional edge taping machinery.
