Abstract
A locking mechanism for a refuse container that includes a pivotally mounted bracket system that constitutes a first pendulum, for securing the lid of the refuse container and a catch which can be moved from a potentially engageable position to an unengageable position to control movement of the bracket system. The catch constitutes a second pendulum. During an automated emptying of the refuse container, the pendulums are timed so that the catch opens first, thereby allowing the bracket system to pivot and the lid to open.
Claims3
A locking mechanism whereby selective access to a secured refuse container is achieved, said refuse container being generally a closed structure having a void within and having a lid which can be opened whereby allowing access to said void within, a means secured to said refuse container designed for cooperation with an external truck mounted mechanism whereby said refuse container can be manipulated for dumping, said locking mechanism comprising:
- a gravity locking device secured to said refuse container having a first lid securing bar pendulum and a second catch pendulum for securing said lid whereby at a predetermined point during said manipulation of said refuse container, said second catch pendulum activates, and at another predetermined point during said manipulation said first lid securing bar pendulum activates, whereby said lid is free to open;
- a mounting system securing said first lid securing bar pendulum to said container whereby movement is possible therebetween in response to the pull of gravity;
- a catch pivot securing said second catch pendulum to said mounting system whereby movement is possible therebetween in response to the pull of gravity and said second catch pendulum remains free from engagement unless unauthorized entry to said refuse container is attempted;
- and
- a manual lock associated with said gravity locking device for activating said second catch pendulum whereby said lid may be opened.
A refuse container defining an internal space and having a lid which controls access to said internal space, a means secured to said refuse container for cooperating with an external truck mounted mechanism whereby said refuse container may be picked up, passed along a predetermined path incident to dumping thereof, a locking mechanism for controlling movement of said lid comprising:
- a gravity locking device including:
- an immovable shackle secured to said refuse container;
- a support housing secured to said refuse container carrying an elongated bar rotatable around its major axis;
- a lid securing bar being fixed to said elongated bar and extending outwardly whereby preventing said lid from being opened, said lid securing bar including a first pendulum;
- a catch link having first and second ends, said first end being fixed to said elongated bar;
- a hook pivotally secured to said second end of catch link which can be selectively trapped by said immovable shackle, said hook including a second pendulum, whereby when said refuse container is passed along said predetermined path incident to dumping said hook responding to the pull of gravity moves, whereby said hook is unengageable with said immovable shackle and then said first pendulum responding to the pull of gravity effects said lid securing bar whereby releasing said lid to open and dumping to take place;
- and
- a manual lock device associated with said gravity locking device for activating said hook whereby said lid may be manually opened.
