Abstract
A locking mechanism having a latch and linkage system that automatically unlocks the lid on trash bins when the trash bin is lifted into the air and then automatically re-locks the lid when the trash bin is placed back on the ground. A leg and pod assembly is attached to the linkage system and pulls the linkage system pivotably downward to move the latch away from the lid when the bin is lifted and thereafter pushes the linkage system upward to pivotably move the latch to secure the lid when the bin is repositioned.
