Abstract
An adjustable locking strut is connected to a pair of relatively movable mechanical elements and permits relative motion between these elements below a predetermined motion threshold. Above this predetermined motion threshold relative movement between mechanical elements is prohibited through the engagement of nonoverhauling threaded members connected to the mechanical elements. These nonoverhauling threaded members are specially designed so that when synchronized they do not engage one another. One of the nonoverhauling threaded members which is internally threaded forms a relatively large tubular inertia mass for sensing accelerated movement between the relatively movable mechanical elements. This tubular inertia mass is machined to close tolerances to fit within a cylindrical cavity in the adjustable locking strut so that when the nonoverhauling threaded members are engaged, extremely large forces may be absorbed by the locking strut without damage thereto, there being no roller or ball bearings in the direct force path to cause system failure.
