Abrégé

A locking mechanism (10) for a 'hinge (4) is disclosed. A latch member (11) engages with a lip (12). A positive drive means (20, 23, 24, 41) enables the latch member to be driven into and out of engagement with the lip. The driven engagement when the hinge is used in relation to columns (1, 101) prevents small movements at the hinge being magnified into large movements at the end of the column members. The driven dis-engagement enables the hinge to be opened notwithstanding mechanical loads, corrosion, insect nests and similar obstacles. The drive means preferably takes two forms, namely threaded fasteners (20, 23, 24) and a spring loaded rotatable actuator (41) with ramped surfaces (48, 49) which male with ramped surfaces (61, 62) on the latch member (11).

Abrégé

Rapid deployment modular structures (10, 70) are disclosed including those having multiple storeys (11, 12, 13). Sealing arrangements are disclosed between hinged portions (41, 42, 43) of columns (4), between walls (7) and columns (4), and between adjacent modules (1). The seals include resilient hollow seals (24), wiper blade seals (29) and elongate seals (31, 32, 34, 35) which preferably enable a stagnant air insulative layer to be created, A column (4) having thee portions (41, 42, 43) interconnected by hinges (44, 45) is also disclosed.

Abrégé

An expandable flat pack module (1) is disclosed which has a pitched roof (2). In a storage configuration a plurality of such modules (1) can form a compact stack (7) of modules. A plurality of stub supports (5) are arranged around the periphery of the base (8) each having a substantially identical length sufficient to support the base (8) of a like module ( 1 ) and maintain the base (8) of the like module (1 ) closely spaced from the ridge (3) of the pitched roof (2). Each module (1) can be erected by raising the pitched roof (2) above the base (8) of the module. Preferably two end walls (13) pivoted to the base are provided. Preferably two side walls (10) each having a central, horizontal and inwardly folding piano hinge (12), and pivotally connected to both the roof (7) and base (8), are also provided. Various erection methods and dwelling configurations are also disclosed.
