US Patent 11008788 Door closure

Disclosed is a closure for a door of a shipping container. The closure includes a housing, an outside handle pivotally mounted relative to the housing, an inside handle pivotally mounted relative to the housing, and a catch connected to the inside handle. The closure is configured so that movement of the inside handle between a first position and a second position causes corresponding movement of the catch. A locking mechanism can releasably fix the inside handle relative to the outside handle, such that when in a locked position rotation of the outside handle causes corresponding rotation of the inside handle and when in an unlocked position the inside handle can be rotated independently of the outside handle.
