Extendible height container and shelter

Abstract

An extendible height container is provided in which the corner elements telescope to extend the height of the container from standard ISO dimensions. An enlarged shelter can be formed from the container by providing sides which fold down to form the floor of the shelter and a flexible cover supported above the floor thus created.

What is claimed is: 
     
         1 . A portable, collapsible shelter comprising:
 a) 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;   b) 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;   c) means associated with said container and with said pivoting wall portion for releasably securing said pivoting wall portion in said vertical position;   d) means adapted to support said pivoting wall portion for releasably maintaining said pivoting wall portion in said horizontal position;   e) 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   f) 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.   
     
     
         2 . The shelter of  claim 1  further comprising power means for reversibly telescopically lowering and extending each said inner element within said outer element. 
     
     
         3 . The shelter 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 shelter of  claim 1  wherein said means for releasably maintaining said pivoting wall portion in said horizontal position comprises leveling means. 
     
     
         5 . The shelter of  claim 1  further comprising means for raising and lowering said pivoting wall portion. 
     
     
         6 . The shelter of  claim 5  wherein said means for raising and lowering said pivoting wall portion comprises a cable connected to said pivoting wall portion and winching means. 
     
     
         7 . The shelter of  claim 1  wherein said foldable frame comprises rigid or semi-rigid beams attached to said container at either end of said beams. 
     
     
         8 . The shelter of  claim 7  wherein said flexible cover is constructed from a fabric material. 
     
     
         9 . The shelter of  claim 1  wherein said means for releasably securing said pivoting wall portion in said vertical position comprises a nut and bolt. 
     
     
         10 . The shelter of  claim 1  wherein said means for releasably securing said pivoting wall portion in said vertical position comprises latching means. 
     
     
         11 . The shelter 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. 
     
     
         12 . The shelter 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. 
     
     
         13 . The shelter of  claim 1  further comprising 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. 
     
     
         14 . A portable, collapsible shelter comprising:
 a) 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 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 each said inner telescopic element is in said lowered position;   b) 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;   c) means associated with said container and with said pivoting wall portion for releasably securing said pivoting wall portion in said vertical position;   d) means adapted to support said pivoting wall portion for releasably maintaining said pivoting wall portion in said horizontal position;   e) a flexible cover removably secured to said outer edge of said pivoting wall portion and secured to said container around said opening formed when said pivoting wall portion is in said lowered horizontal position, and adapted to be 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; and   f) a folding frame for supporting said 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 folding 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.   
     
     
         15 . The shelter of  claim 14  further comprising power means for reversibly telescopically lowering and extending each said inner element within said outer element. 
     
     
         16 . The shelter of  claim 15  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. 
     
     
         17 . The shelter of  claim 14  wherein said means for releasably securing said pivoting wall portion in said vertical position comprises latching means.
