Abstract: A lightweight awning frame having the flexibility of being easily lengthened or shortened by the addition or removal of extension pieces, which is easy and inexpensive to manufacture and mass produce, assemble and install, and package in a relatively compact cardboard box. The awning can be produced in various forms with common requirements of multiple bent pipes and non-welded, one piece engageable members wherein the ends of the pipes are inserted and securely engaged for the purpose of forming a semicircular half-dome shaped structure. Standard left and right end sections having a set of awning tubes can be formed into awning ribs by connection or the addition of extension members and support brackets connected at joints spacing the awning tubes apart in an array of awning ribs. One form of the side brackets has two receiving openings and a flange for securing individual tubes.
