  • Locking mechanism with rotatable features
    Patent number: 7097240
    Abstract: A locking mechanism is described that releasably locks at least two objects together. The locking mechanism allows one of the objects to be rotatably connected to the other, allowing for a variety of uses. The rotatability and releasability of the locking mechanism allows several locking mechanisms to be used together as an escape hatch system, particularly for use in race vehicles. The locking mechanism has uses beyond the escape hatch system and is applicable to doors, cover, and other objects that are rotatably attached to a second object.
