Patent ID: 8459704

Claim:
A security system for a hinged barrier, in which the barrier defines an interior space on one side of the barrier and an exterior space on an opposing side of the barrier and a hinged portion on one side edge, the system comprising: a first lock assembly located on the exterior space side of the barrier and comprising a deadbolt and a first actuation mechanism operable from at least the exterior space and configured to move the deadbolt from a first position to a second locking position extending away from the hinged portion; a second lock assembly located on the interior space side of the barrier, the second lock assembly comprising a member extendable from a first position to a second locking position extending away from the hinged portion and substantially parallel to the second locking position of the deadbolt, a second actuation mechanism operable from the interior space and configured to extend the member from the first position to the second locking position and cooperating with the first lock assembly such that actuation of the first lock assembly from the exterior space extends the member from the first position to the second locking position; a receptacle having a first portion for receiving the deadbolt in the locked position and the receptacle having a second portion for receiving the member in the locked position, to thereby lock the barrier when the deadbolt and member are extended into the receptacle; and an override mechanism having engaged and disengaged conditions, operable only from the interior space, and operable separately from the first and second actuation mechanisms, the override mechanism comprising at least two components that matingly engage to prevent the member from being retracted from the locked position and the barrier from being opened when the override mechanism is engaged.
