Abstract:
An interconnect mechanism for a dual lock of the type having a deadbolt, a deadbolt driving mechanism, a latch bolt, a latch bolt driving mechanism with an inside handle, the interconnect mechanism comprising:a base plate adapted to be mounted to an inner side of a door, the base plate including a flange wall on an outer face thereof which faces away from the door, the base plate further including a wing on each of two lateral sides thereof, the flange wall including a top face, a lower portion, and an upper portion;a lower cam rotatably mounted to the lower portion of the flange wall, the lower cam being operably connected to the inside handle to rotate therewith, the lower cam including a lobe located above the top face of the flange wall,an upper cam rotatably mounted to the upper portion of the flange wall, the upper cam being operably connected to the deadbolt driving mechanism, the upper cam including a lobe located above the top face of the flange wall; anda slide plate including a vertical slot in each of two lateral sides thereof, each said vertical slot being extended through by an associated said wing on the base plate, thereby allowing vertical sliding motion of the slide plate relative to the base plate, the slide plate including an upper operative end operably connected to the lobe of the upper cam and a lower operative end operable connected to the lobe of the lower cam, whereby rotational movement of the inside handle causes rotation of the lower cam, vertical sliding movement of the slide plate, and rotation of the upper cam, thereby retracting the deadbolt and the latch bolt simultaneously.
