ABSTRACT:
The present disclosure relates to automatic gravity actuated container lid locking mechanisms for bulk trash containers, wherein the mechanism comprises a counterweighted actuator arm pivotally attached to a first housing affixed to a first sidewall of the container, a crossbar across the lid of the container, and a dummy arm pivotally attached to a second housing affixed to a second sidewall of the container. The crossbar may pivot forward to unlock the lid when the container is tilted up for dumping. Alternatively, the crossbar may be pivoted forward when the lock is manually unlocked by sliding a counterweighted pin assembly on the first housing from a position interfering with the motion of the actuator arm to a position allowing the motion of the actuator arm.
