ABSTRACT:
A lock assembly for a shipping case includes a rotatable knob received within an aperture of a lid. A latch bar rotatable with the knob is engageable with a ramped ledge in a protruding hub of the base. Rotating the knob secures the shipping case lid to the base. The knob includes a lock operator pivotally attached within a channel formed in a bowl of the knob. A lock beam of the lock operator, upon rotation of the knob, is engageable with any one of a plurality of detents formed in the lid that define the open, closed and locked states of the shipping case. A resilient spring plank formed integrally with the lock operator engages a recess formed in the knob and acts to bias the lock beam into engagement with the detents. A fastener assembly mounts the latch bar to the knob.
