ABSTRACT:
A support frame and method of making and packaging such frame which comprises a pair of similarly constructed end supports formed of readily bendable structural members, each having a specifically constructed notch configuration about which the structural members can be readily bent to define an inverted U-shaped end support. The arrangement is such that the ends of side rails for maintaining opposed end supports in predetermined spaced relationship are disposed within the respective notches whereby the notches closed about the end of a corresponding side rail to positively secure the rails to the end support during the bending and forming of the U-shaped end support. The structural members and side rails defining the complete support frame are packaged as elongated rectilinear members in complementary pairs with the side rails packaged between a pair of elongated unbent end support members so as to occupy a minimum of space for shipping or packing. Cross pieces are also provided for interconnecting the opposed leg portion of a formed end support, and which cross pieces can be readily nested between the elongated complementary end forming structural members in the packaged position.
