Abstract: An adjustable bracket-standard mounting arrangement for supporting shelving systems is disclosed in which the bracket is secured to the standard by a frictional interengagement therebetween established by movement of the bracket from a tilted position to the adjusted horizontal position at the selected height. The standard consists of a boxed channel having a longitudinal slot on its front side, which retains the bracket by receiving a pair of laterally extending ears on the top of one end of the bracket. The bracket is formed in a T-section, including a gusset plate having a tail portion extending to the rear of the bracket ears, moved into engagement with a track or slot extending along the rear wall of the box channel upon locking of the bracket in position. Locking frictional forces are established between the tail portion and the rear and side of the track.

Abstract: An adjustable shelving system comprises two or more upright standards each having a forwardly projecting shelf support member pivotably depending therefrom which is infinitely vertically adjustable therealong. When positioned horizontally, the support members lockingly engage with their respective standards. The members secure a shelf by means of brackets which are mechanically affixed to the shelf and spaced to define rearwardly opening cavities which receive the support members. Each shelf comprises a wire grid of a plurality of longitudinally and laterally disposed members. Each bracket has outwardly projecting tabs which encircle two adjacent longitudinal members of the shelf. Each bracket also has a raised central portion and downwardly, inwardly projecting tabs which collectively embrace the shelf support member.
