Abstract

An aircraft flight control stick is mounted on a gimbal which provides left, right, forward and aft pivotal motion of the stick. A pivot member that is mechanically linked to the aircraft flight controls is attached to the gimbal through a uni-ball bearing which allows the pivot member to pivot independently of the control stick. A bell-shaped housing is slidably mounted on the control stick. The housing is spring-biased downward toward the pivot member so that a stud protruding upward from the pivot member plugs into a socket in the housing. A lever assembly mounted on the control stick and attached to the housing can be actuated to slide the housing away from the pivot member, thereby unplugging the stud from the socket to disengage the control stick from the aircraft flight controls. The downward facing housing circumscribes all possible motion of the stud while the control stick is disengaged. Release of the lever assembly allows a spring to urge the housing downward toward the stud. The conical-shaped interior of the housing guides the stud into the socket to reconnect the control stick to the pivot member and the aircraft flight controls. The reconnection of the control stick…
