Double latch lockset

A double latch lockset comprising:

• a first retractable latch configured to be activated by a first inside and/or outside actuator;
• and
• a drive cam driven by the first inside and/or outside actuator;
• a second retractable latch configured to be activated by a second inside and/or outside actuator;
• a latch trigger driven by the second inside and/or outside actuator to project and retract the second retractable latch;
• and
• a transmission that asymmetrically couples the drive cam to the latch trigger, the transmission configured to transmit motion of the drive cam to the latch trigger to cause the first and second retractable latches to retract in tandem, while preventing a sufficient transmission of motion of the latch trigger from transmitting sufficient motion to the drive cam to retract the first retractable latch.

A drive assembly that connects a first retractable latch and a deadbolt within a double latch lockset, the drive assembly comprising:

• a drive cam;
• a first reactor plate mounted for rotation about a pivot point;
• a second reactor plate;
• and
• a deadbolt trigger;
• wherein when the drive assembly is assembled:
• the drive cam is configured when rotating in a clockwise direction to drive the first reactor plate to rotate in a counterclockwise direction about a pivot point, and when rotating in a counterclockwise direction to drive the first reactor plate to rotate in a clockwise direction;
• the first reactor plate is configured to act on the second reactor plate;
• the second reactor plate is configured to act on the deadbolt trigger;
• and
• a coupling between the first and second reactor plates configures the first and second reactor plates to move substantially in unison to operate the deadbolt unless movement of either the first or second reactor plates is blocked relative to the other.
