Abstract
A bi-directional locking ring assembly is provided comprising a housing and a gear having a plurality of teeth. The gear is coupled to the housing to rotate in opposite directions about a rotational axis. A pin is also coupled to the housing and has an apex configured to travel along a line that does not pass through the rotational axis of the gear. The pin is configured to translate between (1) a disengaged position wherein the gear is free to rotate, and (2) an engaged position wherein the apex resides between two of the plurality of teeth to prevent rotation of the gear in both rotational directions. A pin actuator is coupled to the housing and configured to engage the pin to selectively lock the pin in the engaged position.
