Abstract: A locking linkage system may comprise a lockable assembly comprising an upper brace, a lower brace coupled to the upper brace, and a linkage coupled to the upper brace and the lower brace. The locking linkage system may further comprise a downlock actuator comprising an electric motor coupled to the upper brace, a rotary output shaft coupled to the electric motor, a connecting output coupled to the rotary output shaft, wherein the connecting output shaft is configured to rotate between a fixed locked position and a fixed unlocked position, and a link rod having a distal end coupled to the linkage and a proximal end comprising a lost-motion joint, the lost-motion joint being coupled to a connection pin of connecting output shaft. The downlock actuator may be configured to toggle the linkage, the upper brace, and the lower brace between an unlocked position and a locked position.
