Transportable and expandable building structure

摘要

Described embodiments relate to a transportable expandable building structure for human occupancy. The building structure comprises at least first, second and third frame modules arranged to nest with each other in a contracted position and to telescopically expand into an expanded position. One of the first, second and third frame modules is a base unit frame module that forms part of a base unit and the other frame modules are arranged to be movable away from the base unit to adopt the expanded position. The base unit has a fixed floor and is arranged to support the building structure in the contracted position to enable transportation of the building structure by road. Each of the frame modules is different in size from an adjacent one10 of the frame modules and comprises a floor portion, a roof portion and opposed side portions. Each side portion defines a same-sized modular insert region to receive modular door, window or wall inserts.

1. A transportable expandable building structure adjustable between a contracted state to enable transportation of the building structure, and an expanded state to provide the building structure for human occupancy, the expandable building structure comprising:
at least first, second and third frame modules arranged to nest with each other in the contracted state and to telescopically expand into the expanded state, wherein one of the first, second and third frame modules is a base unit frame module that forms part of a base unit comprising a fixed floor arranged to support the building structure in the contracted state, and the other frame modules are expander modules comprising wheels or rollers and arranged to be movable away from the base unit to adopt the expanded state; and tracks associated with each of the expander modules, each track comprising:
a fixed portion fixed to an adjacent one of the frame modules to the associated expander module to support the associated expander module in the contracted state; andan extension portion hingedly coupled to the adjacent frame module to support the associated expander module in the expanded state, wherein the extension portion is rotated up alongside the adjacent frame module in the contracted state and is rotated out so as to extend away from the adjacent frame module in the expanded state, such that the fixed portion and extension portion are aligned and together define a channel configured to receive the wheels or rollers of the associated expander module and to allow movement of the expander module along the track between the contracted state and the expanded state, and wherein each of the frame modules is different in size from the adjacent one of the frame modules and comprises a floor portion, a roof portion and opposed side portions.
