Component cart assembly

A cart assembly for transporting parts through a manufacturing facility, the cart assembly comprising:

• a base having a plurality of wheels, and disposed on a plane defined by an X axis and a Y axis;
• a shelf support structure orthogonally arranged with respect to the base, and extending from the base along a Z-axis;
• at least one shelf supported by the shelf support structure;
• and
• a swivel mechanism rotatably interconnecting the base and the shelf support structure for rotation about an axis of rotation, such that the shelf support structure and the at least one shelf are selectively rotatable with respect to the axis of rotation relative to the base, wherein the swivel mechanism includes:
• a race that rotates with the shelf support structure about the axis of rotation;
• wherein the race defines a plurality of sockets disposed annularly about the axis of rotation, on an outer circumference of the race;
• a retractable pin connected to the base, wherein the retractable pin is moveable between an engaged position for interlocking engagement with one of the plurality of sockets to position the shelf support structure relative to the base and prevent rotation of the race and the shelf support structure about the axis of rotation relative to the base, and a disengaged position disengaged from all of the plurality of sockets of the race to allow rotation of the race and the shelf support structure about the axis of rotation;
• a spring operable to bias the retractable pin into the engaged position;
• and
• a pin actuator coupled to the retractable pin, and operable to move the retractable between from the engaged position into the disengaged position.
