Storage rack having latched beam-to-column connection

A storage rack comprising a column, a beam, and means for connecting the beam to the column at one end of the beam and latching the beam to the column, even if the beam is lifted in relation to the column, the column having a front wall with a vertical array of similar, spaced apertures and a side wall, each aperture having an upper region and a lower region with the lower region being narrower in width than the upper region, each aperture having a continuous margin defined the front flange, the connecting means comprising a flanged member having a side flange integral with the end of the beam and a front flange having a vertical slot, the side flange being fitted against the side wall of the column, the front flange being fitted against the front wall of the column, a connecting pin mounted rigidly to the front flange and projecting through a selected one of the apertures of the vertical array, the connecting pin being removable from the selected aperture only if the beam is lifted to an elevated position, and a latching pin mounted to the front flange so as to be slidably movable along the vertical slot of the front flange and projecting through a separate aperture of the vertical array, the latching pin defining an axis and being removable axially from the separate aperture only if lifted, the latching pin having an inner head and being biased downwardly so that the beam remains latched to the column by the latching pin, even if the beam is lifted to the elevated position where the connecting pin is removable from the selected aperture, and so that the beam is detached from the column by further lifting the latching pin above a latching zone, in which the inner head of the latching pin is prevented by the margin at the lower region of the separate aperture from being removed axially through the separate aperture, so as to be removable axially from the separate aperture.
