Abstract: The doorlock safety chain release mechanism comprises an anchor fixture mounted to a door frame and a door plate assembly mounted to the door. The door plate assembly has a horizontal channel with a horizontal slot in the front wall of the channel. A chain has one end thereof attached to the anchor fixture and a release connector is mounted to the other end. A slider is mounted in the channel. The release connector has a ball-detent connector mounted therein, and engaged into the slider. The ball-detent connector is operable by depressing the plunger of the connector through the slider and into a hole in the backing plate of the channel. An operation of the ball-detent connector is checked by the backing plate when the plunger is unaligned with the hole in the backing plate. Applications for this lock mechanism are not limited to door locks.
