Abstract: A carrousel tool box having a cabinet, a carrousel of trays mounted for rotation within the cabinet, and a shaft attached to the carrousel along the axis of rotation of the carrousel of trays and extending outwardly through the cabinet, with a locking crank for turning the shaft. The locking crank includes an arm attached to the shaft, a handle pivotally mounted to the end of the arm, a fulcrum on the arm, a spring-biased locking pin which engages with openings in a plate on the cabinet, and a lever pivoted on the fulcrum and operated by the handle for causing the locking pin to lock or unlock the rotation of the carrousel in response to movement of the handle from a locking position to a cranking position. The arm has guides for constraining the lever to sit on the fulcrum and for limiting the movement of the lever. The tool box has various drawers and a lid with side slots which slidably and pivotally hinge on a pair of hinge posts on the sides of the cabinet.
