Abstract: A wall structure includes first and second panels joined to form a stud and a first wall layer. A fastener extends through the first wall layer and into the stud. Each panel includes first and a second ends. The first end of one panel and the second end of the other panel form a portion of the stud. The ends of the panels can nest. The wall structure can include multiple wall layers arranged such that the seams formed by components of each wall layer are staggered with respect to the seams in adjacent wall layers. Reinforcing members and fasteners can secure the wall layers to the remainder of the structure. A similarly constructed roof structure can be joined with multiple wall structures to form a building.

Abstract: A wall structure includes a first panel, a second panel joined to the first panel to form a stud and a first wall layer. A fastener extends through the first wall layer and into the stud. Each panel includes a first end and a second end. The first end of one panel and the second end of the other panel can form at least a portion of the stud. The ends of the panels can nest to form a portion of the stud. The wall structure can include multiple wall layers arranged such that the seams formed by individual members of each wall layer are staggered with respect to the seams formed by individual members of the adjacent wall layers. Reinforcing members and fasteners can be used to secure the wall layers to the remainder of the wall structure. A roof structure includes a first panel, a second panel joined to the first panel to form a stud and a first roof layer. A fastener extends through the first roof layer and into the stud. Each panel includes a first end and a second end.

Abstract: A cabinet includes at least two doors located on opposite sides of the cabinet. The cabinet includes an interlocking means comprising a pair of release mechanisms, locking mechanisms, and latching mechanism. The latching mechanism functions to retain the doors in the closed position unless activated by an operator, allowing the doors to be opened. The locking mechanism prevents the latching mechanism from being activated when the opposing door is open. The release mechanism communicates the position of the door to the locking mechanism associated with the other door.
