Deadbolt assembly for simultaneously securing co-mounted doors together and actuating at least one deadbolt

A door assembly for selectively interlocking first and second co-mounted doors each pivotably mounted at a hinge side thereof to a door frame so as to both open and close in the same rotary direction, the door assembly comprising:

• a door jamb, the door jamb including a hinge-side jamb spaced apart from a latch-side jamb;
• the first door, the first door having a hinge side and a latch side opposite the hinge side thereof;
• the second door, the second door having a hinge side and a latch side opposite the hinge side thereof, the hinge sides of the first and second doors both pivotably mounted to the hinge-side jamb such that the first and second doors pivot individually or together in the same rotary direction relative to the hinge-side jamb between open and closed positions;
• and
• a deadbolt assembly for securing the first and second co-mounted doors together and activating at least one deadbolt, the assembly comprising:
• a first-side assembly to be mounted to the first door of the co-mounted doors, the first-side assembly including a first coupling assembly to be mounted to a side of the first door facing the second door of the co-mounted doors, the first coupling assembly including a first rotatable component that is rotatable about an axis of rotation and a first retention component;
• a second-side assembly to be mounted to the second door including a second coupling assembly to be mounted to the second door facing the first coupling assembly so as to interact with one another upon bringing the first and second coupling assemblies toward and proximate to one another, the second coupling assembly including a second rotatable component that is rotatable about the axis of rotation and a second retention component;
• at least one of the first-side assembly and the second-side assembly further including the deadbolt that is operatively connected with at least one of the first and second rotatable components such that rotation of the first or second rotatable component can extend and retract a deadbolt,
• wherein the first and second rotatable components are operatively connectable with one another and the first and second retention components create an interference in an axial direction of the axis of rotation of the first and second rotatable components upon bringing the first and second coupling assemblies proximate to one another along with rotation of at least one of the first and second rotatable components so as to restrict movement of the first and second coupling assemblies away from one another while the interference is created.
