Abstract:
1. A locking device for a container having a hinged lid, said locking device comprising: a base unit adapted to be fixed to said container; a pivoting unit pivotally mounted to said base unit; said pivoting unit including a locking mechanism mounted therein, said locking mechanism comprising a circular rolling member, said base unit includes a base member and a trigger member both adapted to be fixed to said container, said trigger member having a top surface that has a slanted flat rolling surface provided to engage said rolling member, a substantially cylindrical convex cam surface adjacent to said rolling surface at one end thereof and a substantially cylindrical concave cam surface adjacent to said rolling surface at the other end thereof, said rolling member adapted to roll on said top surface of the trigger member between a blocking position in which said rolling member engages said concave cam surface and said pivoting unit thereby preventing relative movement between said pivoting unit and said base unit and a release position when said container, and thus said base unit, is tilted, permitting relative movement between said pivoting unit and said base unit as said rolling member moves from said concave cam surface to said convex cam surface of said trigger member; and a locking bar fixed to said pivoting unit so as to extend substantially across the length of said container, said locking bar being movable between a closed position wherein said locking bar extends over said hinged lid of said container so as to prevent opening of said container, and an open position wherein said locking bar is spaced away from said hinged lid of said container so as to allow the opening of said container.
