A bracket and shelf assembly comprising first and second bracket members, and a shelf member, each of said bracket members being adapted for attachment to a vertical member and to extend transversely of said vertical member, said first and second bracket members or said shelf member comprising a first component provided with button means extending therefrom, the other component of said first and second bracket members or said shelf member being provided with opening means therein, said opening means being adapted to receive said button means to join said bracket means to said shelf member, said opening means being elongated to permit relative sliding movement between said shelf member and said bracket members, said button means comprising a button having a frusto-conically shaped portion extending from a cylindrically shaped shoulder portion, a smaller diameter portion of said frusto-conically shaped portion being joined to said shoulder portion, the extent of said shoulder portion beyond said first component being substantially less than the thickness of a planar portion of said other component having said opening means therein, said opening means comprising an elongated slot having a first portion of a substantially circular configuration and a diameter exceeding a larger diameter of said button member and a second portion having two straight parallel elongated edges and having a width constant along the length of said two edges and less than the diameter of said larger diameter of said button and greater than the diameter of said shoulder portion of said button, such that said edges of said opening second portion impinge upon said walls of said frusto-conical portion of said button and are wedged between said first component and the walls of said frusto-conical portion of said button as said other component is slid along said button means, said wedging action being operative to lock said first and second components together without additional locking means.
