## 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.

## Claims

### Claim 1

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 bolt in the bolt housing, the bolt being elongated and having a first end and an opposite second end, the bolt being movable axially in the bolt housing along its elongated length between a bolt locking position and a bolt unlocking position,
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,
a locking plate having a hole therein, the locking plate being slidably mounted in the bolt housing and movable between a locking plate unlocking 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 locking plate locking position where the locking plate hole is not aligned with the bolt and where the bolt movement toward the bolt second end is limited, and
a locking plate moving mechanism for moving the locking plate between its locking plate locking position and its locking plate unlocking 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,
wherein the latch is a cam mounted on a vertical locking bar mounted on the door, and
wherein the cam engages the bolt first end and moves it axially against the biasing spring as the cam rotates on the vertical locking bar so that the cam can pass past the bolt first end when the locking plate is in its unlocked position.

### Claim 2

A locking mechanism for a swinging door movable between a door closed position and a door open position and including a cam mounted on a vertical locking bar mounted on the door, the locking mechanism including:
a bolt housing,
a bolt in the bolt housing, the bolt being elongated and having a first end and an opposite second end, the bolt being movable axially in the bolt housing along its elongated length between a bolt locking position and a bolt unlocking position,
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 cam engaging the bolt first end and preventing the door from opening if the cam and the bolt first end cannot move past one another,
wherein the cam engages the bolt first end and moves it axially against the biasing spring as the cam rotates on the vertical locking bar so that the cam can pass past the bolt first end when the bolt moves from its bolt locking position to its bolt unlocking position.
