Expandable building assembly comprising rotating roof portion

摘要

The assembly 2 has a retracted condition in which the roof 20 has a first area and an expanded, extended condition in which the roof has a second larger area. The assembly comprises a roof portion which is rotated between the conditions and that in retracted condition the orientation of the roof portion is rotated turned relative to the first orientation. Preferably the roof portion is initially vertical and forms a wall of the assembly in the retracted condition and is horizontal in the extended condition. The assembly may comprise a floor portion 46 which is extended from a retracted condition as a result of the roof portion being extended. The roof portion may move between conditions by having a distal portion which initially moves linearly and then is rotated. The components of the assembly may be expanded and retracted by using interconnected arms or levers. The floor assembly may be unfolded or folded. In the initial condition the roof may lie within the footprint of the assembly but in the extended condition the roof may be partially or wholly outside of the footprint of the assembly.
