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

A deadbolt assembly for securing co-mounted doors together and activating at least one deadbolt, the assembly comprising:

• a first-side assembly to be mounted to a 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 a 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 the deadbolt,
• wherein the first and second rotatable components are operatively connectable with one another, and at least one of the first and second retention components comprises a rotatable retention component that is operatively connected with both the first and second rotatable components so that the rotatable retention component can be driven from either of the first and second rotatable components, and wherein the rotatable retention component includes a radially varying portion to rotate therewith that is in engagement with a radially sliding element of one of the first and second coupling assemblies to move the radial sliding element radially by rotation of the radially varying portion to a position of interference with a structural feature of the other of the first and second coupling assemblies to provide an axial interference of the first and second retention components and so as to restrict movement of the first and second coupling assemblies away from one another while the interference is created.
