ABSTRACT:
A lock assembly for selectively locking a refuse container so that it cannot be manually opened by an unauthorized user, but can be opened automatically by a refuse collection truck when the container is to be emptied. The lock assembly has a locking bar that is attached to a control bar which is pivotally mounted to the refuse container. In one embodiment, the control bar is selectively connected to a spring such that when the container is to be locked, the control bar and locking bar are connected to the spring by a lock and in order to open the container the bias of the spring must be overcome. The spring is set such that this bias is easily overcome by engagement of the coupler of a refuse collection truck. When the lock is removed, the locking bar is separated from the spring and the locking bar freely rotates. In another embodiment, the locking bar is connected to a spring control bar by articulated connecting members. These members can be locked together by a lock so that the locking bar can only be moved by overcoming the spring bias applied to the control bar. When the lock is removed, the locking bar is free to pivot through the articulated connecting members with respect to the control bar.
