Title: Live bolt latching and releasing system

Abstract: A latching system for live bolts as in a door retains the live bolts within the door until the door is closed. A latch holds a live bolt link against travel that would insert the live bolts into the door body jamb until a link lifter forces the link out if the latch against the bias of a hold-down spring. The link lifter can take the form of an inclined surface on a cam mounted on the hinge side of the door. The cam engages the door body jamb as the door closes and travels into the door until the link lifter engages and lifts the link out of the latch.
