COLLAPSIBLE SHELTER A collapsible frame for a portable shelter including a plurality of cover supporting frame bars pivotally mounted at one end on a central hub. The hub includes a pair of vertically spaced apart plates. The frame bars include inverted L-shaped support bars including a generally vertical, ground supported leg and an integral generally horizontal base received between the plates. The terminal end of the horizontal base is pivotally mounted in an aperture provided in one of the plates. One of the plates also includes a plurality of recesses which receive the horizontal base in one position of rotation about its terminal end. A spring mechanism is provided for urging the plates together to hold the horizontal members in the recesses but allowing spreading movement thereof such that the frame bars can rotate between stowed, generally side-by-side positions, and angularly disposed positions received in the recesses.
