Abstract

An articulation lock that includes a first housing, a second housing, and a lockable connection assembly for pivotably connecting the first housing and the second housing together. The lockable connection assembly includes a plurality of apertures arranged upon a portion of the second housing and at least two lock pins, where each of the lock pins is seated within a cavity located within the first housing. The assembly further includes at least one biasing element for creating a biasing force upon each of the lock pins such that each of the lock pins is biased toward the second housing to prevent relative rotation of the first housing with respect to said second housing and also with respect to an engaging member attached to the second housing. The engaging member includes a plurality of protrusions, with one of the protrusions corresponding to each of the apertures in the second housing. Upon pressing the engaging member towards the lock pins, at least two of the plurality of protrusions push the lock pins against the biasing forces of the biasing elements, allowing relative rotation of the first housing with respect to the second housing.
