Title: POSITIVE MECHANICAL ROTARY LOCK
Abstract:
A rotary lock apparatus comprises a structural ground and a shaft rotatable about a shaft axis relative to the structural ground, wherein the shaft includes a detent portion. First and second locking components are displaceable along the shaft axis in opposite directions to cause the detent portion to be engaged and coupled to the structural ground in a manner preventing rotation of the shaft about the shaft axis. The locking components are actuated through a combined displacement distance and are configured such that at least one of the first and second locking components positively causes the shaft to be engaged and coupled to the structural ground to thereby lock the shaft against rotation.
