Three-piece bracket assembly

摘要

A bracket assembly which is capable of being erected without separate fasteners is disclosed. The bracket assembly comprises an upright, an arm having a hook at one end engaging the upright and having a specially-shaped notch in its underside, and a brace extending at an angle between the arm and the upright. One end of the brace has a tip which engages in the arm notch when the brace is pivoted upwardly. A tang on the other end of the brace extends through a hole in the upright to lock the assembly when bent against the upright.
