"SPRING-BIASED TENT FRAME FOOT" The invention relates to a spring-biased foot subassembly for use in the lower corners of a wall panel of a ground tent to yieldably resist the tension placed upon such panels when the diagonally-extending portions of the subframes supporting same in free-standing relation elongate as they move from an inwardly-bowed partially folded relation out and over center where they assume a more or less straight line relation and on beyond into a fully-extended and outwardly-bowed position. The same elements that yieldably resist this tensioning of the wall panel also cooperate therewith to maintain the latter taut and under slight tension once the subframe has moved into its fully-extended and outwardly-bowed wall-supporting position. |
