Abstract: A stair closure mechanism is disclosed. In embodiments, the stair closure mechanism is attached to and deploys in concert with a door separating an overhead crew rest compartment and access stairway from the main cabin. As the door is closed, a closure panel mechanically pivots with the closing of the door into a horizontal deployed position. When in the deployed position, the closure panel conforms to the floor of the overhead compartment, securely blocking the free space between the stairway and the floor from persons in the overhead compartment who might otherwise step or stumble thereinto.

Abstract: Described herein is a novel concept regarding the specific latching mechanism to provide a secure and easily releasable device. The latching mechanism is used to attach an accessory such as a luggage rack to a motorcycle or equivalent. The apparatus adds increased functionality, as well as protection to the internal moving components, protection of the user from the moving components, and in at least one example, a locking mechanism for additional safety and security.
