ABSTRACT:
One or a pair of aligned dovetail grooves secure various shelves to supports depending upon whether the shelf is an upper or lower unit. Vertical supports have male dovetail projections formed on each end for mating with a groove. A wedge projection is formed on the support end adjacent to the male dovetail projection for wedging against the shelf in interference fit when the male and female elements are assembled. Various embodiments for the wedge projection are disclosed. The supports have a width less than that of the shelves so that the dovetail joints are only visible from the shelving rear. The wedge projections are sufficiently small so as to not be observable from the shelving front. A particular shelf construction employs upper and lower shelves each comprising a dual construction of an upper and lower member. A triangular brace is secured to the lowermost shelf for support when the shelving is hung on a wall. All shelving members and supports are secured by identical dovetail joints and are collapsible since no dowels or adhesive is used to permanently secure the elements.
