A method of manufacturing a kit for a cold storage room includes the following steps: determining one or more dimensions of the cold storage room; providing continuously manufactured insulation panels, cut to have a length based on the dimensions of the cold storage room, and having alignment structures formed thereon; cutting one or more of the continuously manufactured insulation panels to have a width based on the dimensions of the cold storage room and to form one or more joints; forming connecting structures on one or more of the continuously manufactured insulation panels, the connecting structures configured to form one or more joints; and providing connection hardware configured to mate with the connecting structures and to form one or more joints.

A connector configured to couple plural wall elements defining rooms or to couple insulating panels that are formed by filling a cavity with a fluid foam material wherein the connector is encased by the foam material, the connector including a housing that forms a base wall arranged in a base plane and a front wall arranged opposite to the base wall in a front wall plane; a pass-through opening formed in the front wall and configured to receive a locking hook; a receiving cavity configured in the housing for at least one locking element, wherein the housing forms an air duct, wherein the air duct extends from the front plane towards the base plane, and wherein the air duct includes an air inlet opening in the base plane and an air outlet opening in the front plane.

A lock retainer for facilitating the secured connection of an adjacent pair of wall frame elements to one another by way of a lock cassette having an actuatable grip portion is disclosed. The lock retainer may comprise a flange portion disposed between a proximal portion and distal portion. A cassette compartment may retainingly engage a portion of the lock cassette with the grip portion remaining outward the lock retainer. The proximal portion is configured to be mounted in a retainer mounting aperture in a frame segment of a wall frame element. The lock retainer may include a retainer detent moveable between a securing and releasing positions. The detent may be resiliently biased toward the securing position. The detent may be on a detent lever having a release actuation portion enabling a user to manually overcome the resilient bias. Also disclosed is a modular wall frame system incorporating the lock retainer.

A connector configured to couple plural wall elements like wall panels, the connector including a coupling including a first support that supports a locking hook that is pivotable from an idle position into an engagement position and movable into an interlocking position; a block including a locking bar that is arranged in a second support wherein the locking hook reaches behind the locking bar in the locking position; and a housing for the coupling or the block, the housing including a housing pass through opening wherein the locking hook passes through the housing pass through opening during a pivot movement from the idle position to the engagement position, wherein the housing includes a first housing half and a second housing half, wherein the housing pass through opening is closed by a cover wall against a pass through of the locking hook.

A modular panel is provided and includes a sill plate, a top plate, a plurality of vertical studs, and having at least one skin applied to a major face of the modular panel that presents a first edge having a waveform profile configured to connect to an opposing edge of an adjacent modular panel. At least one of the vertical studs is an end stud having a connector element configured to be secured to a complementing connector of the adjacent modular panel. Two or more of the modular panels may be connected together to form part of a shelter.

A refrigerator having detachably adjacent cabinets is provided. The refrigerator includes a connection mechanism interposed between cabinets adjacent to each other and connecting the cabinets to each other and a manipulation portion configured to drive the connection mechanism by being manipulated from outside, wherein the connection mechanism is configured for the cabinet on one side is pulled toward the cabinet on the other side by a manipulation of the manipulation portion.

A lock retainer for facilitating the secured connection of an adjacent pair of wall frame elements to one another by way of a lock cassette having an actuatable grip portion is disclosed. The lock retainer may comprise a flange portion disposed between a proximal portion and distal portion. A cassette compartment may retainingly engage a portion of the lock cassette with the grip portion remaining outward the lock retainer. The proximal portion is configured to be mounted in a retainer mounting aperture in a frame segment of a wall frame element.

The detent may be on a detent lever having a release actuation portion enabling a user to manually overcome the resilient bias. Also disclosed is a modular wall frame system incorporating the lock retainer.

A modular shelter, is provided having an assembly of at least one each of a modular wall panel, modular floor portion, and modular roof panel. The modular wall panel having a sill plate, top plate, plurality of vertical studs extending therebetween, and a skin with a first edge having a waveform profile for connecting to an adjacent modular panel; and one of the vertical studs being an end stud and having a first connector element configured to be secured to a first complementing connector element of an adjacent second modular panel; and further each modular roof panel has a peak crosspiece, bottom crosspiece, and plurality of rafters, with the first rafter having an engagement member to be engaged with a complementary engagement member of another modular roof panel, and further a second connector element configured to be secured to a second complementing connector element of a second modular roof panel.

A panel fasteners (20) is disclosed in the form of a hook and cam assembly (21) having two side walls (24) with a boss (27) through which a cam shaft (28) is journalled. The cam shaft has a socket (29) and a round cam (30). A hook (32) is frictionally mounted in camming engagement with the cam. A leaf clutch spring (33) is mounted within a spring mounting notch (36) and in frictional engagement with a substantially round cam engagement hole (34) of the hook. To position the spring into the spring mounting notch and cam engagement hole the spring is pre-compressed prior to mounting it within the spring mounting notch by forcing it through a narrowing channel positioned adjacent the cam.
