ABSTRACT:
A unitary shelf bracket for mounting to vertically spaced holes in a vertical side member to support the ends of a shelf wherein the bracket is self-adjusting and shelf-locking. The bracket is formed of a tough resiliently flexible plastic and has a backplate portion having front and back surfaces and a shelf support member extending horizontally outward normal to the front surface adjacent a bottom end thereof. There is a first peg lying on a centerline of the backplate portion, sized to fit into the holes, and extending outward normal to the back surface adjacent a top end thereof. There is also a second peg similar to the first to fit into another adjacent hole. A plurality of first fingers extend downward from adjacent the top end of the backplate at an acute angle thereto and terminate in respective bottom edges parallel to the shelf support member at different spaced distances therefrom. A pair of upward tilted second fingers are disposed at respective side edges of the shelf support member. The first and second fingers are of a thickness to make them stiffly resiliently flexible. A front one of the second fingers acts as a horizontal stop for a shelf on the bracket.
