Patent ID: 8766117

Claim:
A device for locking a push-pull actuator of a circuit breaker in a pulled-out position, wherein the actuator includes a substantially cylindrical shaft section, and an annular flange circumscribing a distal end of the cylindrical shaft section, comprising: a pair of opposing body sections, each of which includes a proximal and a distal recess arranged in tandem, and a joining member that joins the opposing body sections together with the proximal and distal recesses of the opposing body sections in axial alignment with one another, wherein the proximal recesses of the opposing body sections capture the cylindrical shaft section of the actuator without frictional engagement and the distal recesses of the opposing body sections capture the annular flange of the actuator without frictional engagement when the body sections are joined together around the actuator by the joining member, and an axial interface between the proximal and distal recesses interferes with and prevents passage of the annular flange from the distal to the proximal recesses, and an axial length of the distal recesses exceeds an axial length of the captured annular flange such that the joined body sections are slidably movable over the captured actuator an axial distance corresponding to a portion of the axial length of the annular flange.
