Abstract:
1. A tamper-resistant hinge system for a bar lock assembly, said hinge system comprising: a hinge plate having a pin-receiving portion and a generally planar portion, said pin-receiving portion defining a passageway along a first side of said hinge plate, and said generally planar portion defining a second side of said hinge plate, opposite said first side; at least one fastener at said generally planar portion of said hinge plate, said fastener coupling said hinge plate to a mounting surface, and said fastener having a head portion with an outward face directed away from the mounting surface; a hinge pin disposed in said passageway of said hinge plate; a pivot arm, said pivot arm having a pin-receiving portion defining a passageway that is substantially coaxial with said passageway of said hinge plate for receiving said hinge pin in said passageways, said pivot arm being pivotally coupled to said hinge plate via said hinge pin and pivotable between an open position and a closed position; a lock bar coupled to said pivot arm, opposite said pin-receiving portion of said pivot arm, said lock bar being pivotable with said pivot arm between the open position and the closed position, wherein said lock bar is lockable in said closed position to preclude access to the container; an anti-tamper member extending outwardly from said pivot arm and located between said lock bar and said pin-receiving passageway of said pivot arm, said anti-tamper member having a first side facing said first side of said hinge plate and a second side facing said second side of said hinge plate; and wherein when said pivot arm and said lock bar are in the closed position, said anti-tamper member substantially covers and protects said head portion of said at least one fastener from access to at least said outward face, said pin-receiving portions of said hinge plate and of said pivot arm substantially block access to said head portion from along said first side of said anti-tamper member, and said lock bar substantially blocks access to said head portion from along said second side of said anti-tamper member, and wherein said anti-tamper member is configured to expose said head portion of said at least one fastener when said pivot arm is in said open position.
