1. An expandable wall shelter comprising:
a body;
a movable wall section connected to the body and movable between a retracted position and an extended position;
at least one linkage assembly operably connected between the body and the movable wall section for operably and movably supporting the movable wall section relative to the body for movement of the movable wall section to and between its retracted and extended positions, said at least one linkage assembly comprising: (i) an inner link comprising opposite inner and outer ends; and (ii) an outer link comprising opposite inner and outer ends, wherein:
said inner end of said inner link is pivotally connected to said body;
said outer end of said outer link is pivotally connected to said movable wall section;
said outer end of said inner link is pivotally connected to said inner end of said outer link;
wherein:
said inner end of said inner link pivots relative to said body about a first pivot axis, said outer end of said outer link pivots relative to said movable wall section about a second pivot axis, and said outer end of said inner link pivots relative to said inner end of said outer link about a third pivot axis;
said first pivot axis, said second pivot axis, and said third pivot axis are all parallel with respect to each other and are located in a first common reference plane when said movable wall section is located in said retracted position and are located in a second common reference plane that is transversely oriented relative to said first common reference plane when said movable wall section is located in said extended position;
said first reference plane lies parallel to an outer wall of the movable wall section, and wherein said inner link and said outer link lie adjacent said outer wall of the movable wall section when said movable wall section is located in said retracted position.
