ABSTRACT:
A corner structure for a load supporting frame having a pair of horizontal side members with mitered end portions attached in end abutting relationship. The end portions are inserted in slots longitudinally extending from the upper end of an upright tubular leg. A pair of planar wedge members having a cooperating longitudinal slot and tab respectively are connected to define a predetermined angular relationship corresponding to the angle subtended by the side member end portions. In an alternate embodiment, a single, relatively wide slot longitudinally extends from the upper end of the upright tubular leg and a planar wedge member and an angle wedge member are connected to define the predetermined angular relationship. The attached wedge members are inserted between the side member end portions and the inner wall of the tubular leg to retain each end portion in the slot.
