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 the 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. A synchronizing, overhauling threaded member is utilized to maintain the nonoverhauling threaded elements synchronized below the predetermined motion threshold, but is inoperative above the predetermined motion threshold so that said relative motion between the mechanical elements is prohibited above this threshold.
