Abstract:
A shelving assembly system comprising:an upright member defining a vertical support having formed therein at least a first connecting means comprising a plurality of non-circular, closed apertures formed one above the other on said upright, andat least one shelf support having formed on its side face at least a second connecting means comprising a plurality of tabs each shaped to engage an edge of one of said apertures, said apertures being shaped to engage said first connecting means in locking fashion for supporting a shelf end thereon,wherein said first and second connecting means are oriented at an angle with respect to said upright member, said angle guiding engagement therebetween by combined horizontal and vertical motion,and wherein said tabs and apertures maintain locking engagement between said shelf support and said upright member, by developing oppositely-directed forces therebetween, when said shelf support is attached to said upright member in cantilever fashion,said oppositely-directed forces on the tabs at the aperture edges acting edge-on on the edges of said tabs, said forces being opposed by the shear strength associated with said tabs, enabling relatively high shelf loading.
