ABSTRACT:
An alignment and locking system includes a dovetailed male portion having partial female threads formed in a surface thereof, a housing having a dovetailed notch for slidingly receiving the male portion, and a screw assembly coupled to the housing. The screw assembly includes a rotatable rod having a threaded region that partially extends into the housing's notch. The threaded region includes a partially threaded portion and a fully threaded portion. The partially threaded portion is defined by (i) a first region that cannot engage the partial female threads of the male portion as it slides in the notch, and (ii) a second region that can engage the partial female threads of the male portion as it slides in the notch. The system is further configured to impart a biased rotational movement to the rod to align the first region of the partially threaded portion with the notch when the male portion is not engaged in the notch.
