Abstract
Collapsible portable self-supporting shelter structures having from at least two component quad sections to seven or more component quad sections, which joined end to end form the width of the structure; and, said entire component sections optionally being joined side to side form a desired depth of the portable shelter. The resulting structure is a collapsible self-supporting prefabricated deployable shelter having a clear span interior without supporting columns.Some versions of the collapsible portable self-supporting shelter structure due to its configuration may optionally contain a floating hub which is a top element extending above the structure's standard exterior matrix frame. The floating hub forms a high pitch atop the shelter, which high pitch causes the fabric, which covers the matrix frame, to be maintained in a taut downward-sloping condition over the shelter top surface so no rain or snow collects in the fabric at the top of the shelter.
