In a storage rack, a beam is connected at one end to the column having a front wall with a vertical array of similar apertures and a side wall. Each aperture is wider at an upper region and narrower at a lower region. A flanged member has a side flange integral with the end of the beam and a front flange. A connecting pin mounted rigidly to the front flange and projecting through a selected aperture has an inner head narrower than the upper region of the selected aperture but wider than the lower region thereof and a shank narrower than the lower region thereof. A latching pin mounted to the front flange so as to be slidably movable along a vertical slot of the front flange and projecting through a separate aperture has an outer head wider than the vertical slot, an inner head narrower than the upper region of the separate aperture but wider than the lower region thereof, and a shank and is biased gravitationally along the vertical slot so that its shank continues to pass through the lower region of the separate slot, even if the beam is lifted to a position where the inner head of the connecting pin can pass through the upper region of the selected aperture, unless the latching pin is lifted to a position where the inner head of the latching pin can pass through the upper region of the separate aperture. Two connecting pins may be similarly employed.

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, and each aperture having a continuous margin defined by the front wall, the connecting means comprising (a) a flanged member having a side flange integral with the end of the beam and a front flange, the side flange being fitted against the side wall of the column, the front flange being fitted against the front wall of the column, the front flange having a vertical slot extending between an upper margin defined by the front flange and a lower margin defined by the front flange, (b) a connecting pin mounted rigidly to the front flange and projecting through a selected one of said apertures of the vertical array, the connecting pin defining an axis and having an inner head sized and shaped so as to be capable of passing axially through the upper region of the selected aperture but not axially through the lower region of the selected aperture and a shank interposed between the inner head of the connecting pin and the front flange, sized and shaped so as to be capable of passing axially through either of the upper and lower regions of the selected aperture, the inner head of the connecting pin being spaced axially from the front flange by a fixed distance, and (c) 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 one of the apertures of the vertical array, the latching pin defining an axis and having an outer head sized and shaped so as not to pass axially through the vertical slot and an inner head sized and shaped so as to be capable of passing axially through the upper region of the separate aperture but not axially through the lower region of the separate aperture, the latching pin having a shank interposed between the outer and inner heads of the latching pin and sized and shaped so as to be capable of passing axially through the vertical slot of the front flange and axially through either of the upper and lower regions of the separate aperture, the latching pin being biased gravitationally along the vertical slot of the front flange so that the shank of the latching pin rests on the lower margin of the separate slot so as to latch the beam to the column, even if the beam is lifted in relation to the column to a position where the inner head of the connecting pin can pass axially through the upper region of the selected aperture, unless the latching pin is lifted along the vertical slot, 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 through the separate aperture, to a position where the inner head of the latching pin can pass axially through the upper region of the separate aperture.
