<p>In a structural supporting frame the problem of compact storage and shipping and easy assembly and disassembly is solved by providing a frame structure and method of making including a pair of similarly constructed end supports (22) arranged to define an inverted U-shaped member, each having a specified notch configuration formed at the comer portions of the respective U-shaped members for receiving and securing the end portions of opposed side rails (23) for maintaining the end supports in a stable predetermined spaced relationship, and optional cross rails (24) detachably interconnected between the opposed leg portions (30) of the respective end supports. The method of forming such frame structure includes the steps of forming a notch (26) at spaced intervals along a readily bendable length of a stock material (30) whereby the length of stock material can be readily bent into an inverted U-shaped end support (27) in a manner whereby a side rail (23) is gripped and secured at the bent comers of the end supports, and securing a cross rail (24) between the opposed leg portions of the bent supports.</p> |
