Abstract
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.
