Transportable building module with two structures

Abstract

A transportable building module includes a first structure for defining a first enclosed space when erected at a building site and at least one elongate structural component having at least two elements that are relatively linearly slideable for linearly extending the structural component. The structural component is part of or attached to the first structure and is upright when the first structure is installed at the building site, whereupon the structural component is linearly extensible to provide part of a second structure for defining a second enclosed space above the first space.

1 . A transportable building module, including:
 a first structure defining a first enclosed space when erected at a building site, the first structure having a ceiling;   at least one elongate structural component having at least two elements that are relatively linearly slideable for linearly extending said at least one elongate structural component, said at least one elongate structural component being part of or attached to said first structure and is upright when said first structure is installed at the building site; and   a second structure defining a second enclosed space above said first enclosed space, the second structure having a floor comprising at least a portion of the ceiling of the first structure, wherein part of the second structure is provided by said at least one elongate structural component being linearly extended.   
   
   
       2 . A transportable building module according to  claim 1 , wherein said two elements are members of respective wall frames for the first and second enclosed spaces. 
   
   
       3 . A transportable building module according to  claim 2 , wherein one of the wall frames is an internal wall of the first structure. 
   
   
       4 . A transportable building module according to  claim 2 , wherein the wall frames include wall panels. 
   
   
       5 . A transportable building module according to  claim 1 , wherein one of the two elements of the elongate structural component is slideable within the other of the two elements, such that when the structural component is in its retracted condition, said one element is telescopically housed within the other element. 
   
   
       6 . A transportable building module according to  claim 2 , wherein one of the two elements of the elongate structural component is slideable within the other of the two elements, such that when the structural component is in its retracted condition, said one element is telescopically housed within the other element. 
   
   
       7 . A transportable building module according to  claim 1 , wherein the two elements are adjacent one another and one is slid over the other. 
   
   
       8 . A transportable building module according to  claim 2 , wherein the two elements are adjacent one another and one is slid over the other. 
   
   
       9 . A transportable building module according to  claim 1 , wherein there are at least two of said elongate structural components mutually spaced apart. 
   
   
       10 . A transportable building module according to  claim 1  wherein said elongate structural component(s) carries an assembly of roof and/or wall members expansible to form a further part of said second structure.
