Abstract:
1. A specimen container carrier for engaging a container on a conveyor in a laboratory automation system, comprising: a base circular body having a plurality of pivoting holes, a plurality of spring coupling pintles, and a pin; a closure member having a plurality of pivoting holes, wherein the base circular body and the closure member are attached to form a cavity; a plurality of centering fingers, each finger including at least one tooth, a lower pivoting hinge operatively engaging the pivoting hole of the base circular body, and an upper pivoting hinge operatively engaging the pivoting hole of the closure member, and a spring coupling pintle, the fingers vertically extending over the base circular body; a circular rotor provided with a plurality of slits and a rotor cavity rotatably mounted on the pin of the base circular body such that the circular rotor is disposed within the cavity; and a plurality of springs, each spring elastically connecting one of the plurality of fingers with the base circular body by coupling each base circular body pintle and the finger pintle, in order to provide an inward rotation of the fingers along the lower and upper hinges so that the container is grasped by the fingers, wherein the at least one tooth of the finger rotatably engages with the slit of the circular rotor in order to synchronize and balance the inward force of each finger, providing a centering action on the container.
