Abstract
A support bracket is mounted to a vertical wall structure which includes an inner surface and a plurality of spaced slots through the use of a bracket retainer. The bracket has a pair of L-shaped projections extending from its proximal end for hooking through respective slots. Each of the projections includes an edge facing the distal end of the bracket. A recess is provided in the bracket and has a locking edge extending at a downwardly convergent angle with respect to the proximal end of the bracket. The bracket retainer has first and second spaced plates interconnected by a wedge-shaped structure which has a locking surface complemental to the locking edge. The bracket is received between the plates and the locking surface engages the locking edge to force the edges of the L-shaped projections against the inner surface of the wall structure in response to a tap on one end of the retainer.
