This patent discloses a novel load dual path connector for pivotally joining a movable member to a structural member. It comprises a pair of spaced apart lugs attached to a first of the members, each of the lugs including an outwardly projecting boss, a clevis disposed between the lugs and attached to the first member, a pivot pin, received by the lugs and clevis, which may support a self-aligning bearing between the ends of the clevis, and a connecting link assembly including a first connecting link pivotally supported at a first end to the second member, and a pair of second connecting links pivotally supported at respective first ends on the bosses and at the second ends to the second member, the first connecting link, pin and clevis providing a first load bearing path between the structural and movable members, and the second connecting links, bosses and lugs providing a second load bearing path. An alternative, a pair of spaced apart fail safe lugs attached to the first member and a pair of flanged bushings received by the lugs may be used to provide a first load bearing path along the first connecting link, pin and lugs and a second load bearing path along the second connecting links, flanged bushings, and lugs. In each embodiment including a bearing the second link members may be pivotally connected with large tolerances to permit the first link to pivot about an axis perpendicular to the axis of the pin to impart a degree of self-alignability to the connector.
