Patent ID: 12000184

Abstract:
A locking mechanism for a swinging door movable between a door closed position and a door open position and including a latch, the locking mechanism including a bolt housing, a movable bolt slidably mounted in the bolt housing, the movable bolt having a first end and second end, and a spring mounted in the bolt housing between the bolt second end and a portion of the bolt housing and biasing the bolt towards the bolt first end. The locking mechanism also includes a locking plate having a hole therein, the locking plate being slidably mounted in the bolt housing and movable between a bolt unlocked position where the locking plate hole is aligned with the bolt so that the bolt can move freely towards the bolt second end, and a bolt locked position where the locking plate hole is not aligned with the bolt and where the bolt movement toward the bolt second end is limited. The locking mechanism also includes a locking plate moving mechanism for moving the locking plate between its bolt locking position and its bolt unlocked position, the latch engaging the bolt first end and preventing the door from opening if the latch and the bolt first end cannot move past one another.
