Extendible height container and shelter

1. A method of constructing a shelter comprising walls, a floor and a roof enclosing a living space from a portable collapsible shelter, wherein said portable, collapsible shelter comprises:

i) a rigid, hollow container comprising opposed ends, opposed vertical sides, a horizontal top and bottom and four corner rail elements, and wherein said corner rail elements each comprise outer and inner telescopic elements, each said inner element being secured at its upper end to said horizontal top and being reversibly telescopically slidable within said outer element between a lowered position for transit and an extended position when not in transit;

said ends, sides, top and bottom being secured to form a rigid container having ISO Series 1 freight container external dimensions and corner fitting locations when said inner telescopic elements are in said lowered transit position;

ii) at least one of said vertical sides comprising a pivoting wall portion hingedly connected to said vertical side along the lower edge of said pivoting wall portion to pivot between a closed vertical position whereby said pivoting wall portion forms part of said at least one of said vertical sides of the container when said inner telescopic elements are in said lowered position for transit and an open horizontal position, said pivoting wall portion having an outer edge, and whereby an opening is formed in said vertical side when said pivoting wall portion is in the horizontal position;

iii) means associated with said container and with said pivoting wall portion for releasably securing said pivoting wall portion in said vertical position;

iv) means adapted to support said pivoting wall portion for releasably maintaining said pivoting wall portion in said horizontal position;

v) a foldable frame for supporting a flexible cover above said pivoting wall portion while said pivoting wall portion is in said lowered horizontal position and said inner element is in said extended position, said foldable frame being removably attached to said outer edge of said pivoting wall portion and to said container when said pivoting wall portion is in said lowered horizontal position; and

vi) a flexible cover removably secured to said foldable frame, to the edges of said pivoting wall portion and to the edges of said opening in said vertical side to be thereby supported above said pivoting wall portion when said pivoting wall portion is in said lowered horizontal position thereby forming an enclosed space above said pivoting wall portion open to the interior of said container when said pivoting wall portion is lowered to the horizontal position;

said method comprising:

a) lowering at least one pivoting side wall portion hingedly connected along one edge thereof from a closed vertical position to an open horizontal position;

b) partially extending each said inner telescopic element;

c) attaching said foldable frame to said outer edge of said pivoting wall portion and to said container when said pivoting wall portion is in said lowered horizontal position;

d) further extending each said inner telescopic element to its fully extended position;

e) securing each said inner telescopic member and said foldable frame in said fully extended position; and

f) installing said flexible cover on said foldable frame.

2. The method of claim 1 wherein said portable collapsible shelter further comprises power means for reversibly telescopically lowering and extending each said inner element within said outer element.

3. The method of claim 2 wherein said power means for reversibly telescopically lowering and extending each said inner telescopic element within each said outer telescopic element comprises a hydraulic cylinder.

4. The method of claim 1 wherein said portable collapsible shelter further comprises means for raising and lowering said pivoting wall portion.

5. The method of claim 4 wherein said means for raising and lowering said pivoting wall portion comprises a cable connected to said pivoting wall portion and winching means.

6. The method of claim 1 wherein said foldable frame comprises rigid or semi-rigid beams attached to said container at either end of said beams.

7. The method of claim 1 wherein said flexible cover is constructed from a fabric material.

8. The method of claim 1 wherein said flexible cover when supported on said foldable frame extends from an edge of said horizontal top above said pivoting wall portion while said pivoting wall portion is in said lowered horizontal position and is secured to said container around said opening and to outer edges of said pivoting wall portion.

9. The method of claim 1 wherein said foldable frame comprises a collapsible frame secured at a lower end thereof to said pivoting wall portion and at an upper end thereof to said container.

10. The method of claim 1 wherein said portable collapsible shelter further comprises a flexible cover extending between a top edge of one of said end walls and an edge of said horizontal top when said inner telescopic elements are in said extended position.
