Abstract:
1. A combined automatic latch and deadbolt assembly for a door in a doorframe defining a deadbolt socket and a latch socket, comprising: a latch; a deadbolt configured to selectively assume a cocked and a released configuration in which the deadbolt engages in the deadbolt socket, the deadbolt defining a deadbolt feature; a gear coupled to the latch, and a mechanical coupling that couples the latch to the deadbolt, the mechanical coupling including a deadbolt pin that is configured such that movement of the latch out of the latch socket causes the gear to move and to engage the deadbolt pin with the deadbolt feature to cause the deadbolt to assume the cocked configuration, and such that movement of the latch into the latch socket causes the gear to move and to disengage the deadbolt pin from the deadbolt feature to cause the deadbolt to transition from the cocked configuration to the released configuration and to engage in the deadbolt socket.
