An automatic locking apparatus releasably locks together a studded end pla te connector to a notched vertical frame column of a storage rack. The automati c lock includes a vertical lever positioned adjacent one surface of an end plate connector whe n the end plate connector is mounted on a vertical frame column. A locking pin and tension support extend from the inside face of the vertical lever through the end plate connector. The tension support has a protruding end extending past the end plate connector and a tension device mounted on the protruding end to create a force for pulling the inside face of the vertical lever toward one surface of the end plate connector. The locking pin has a length that allows it to extend through the top of a notch or other aperture in the frame column when studs of the end plate connector are positioned in the bottom of corresponding notches in the frame column, preventing withdrawal of the studs from the notches. The locking pin automatically retracts as the end plate connector comes into contact with the frame column and automatically locks after the studs slide into the bottom of their corresponding notches of the vertical frame. The end plate connector can later be disconnected from the vertical column by pulling on the vertical lever to withdraw the locking pin, allowing the studs to slide up from the bottom of the notches. |
