    Abstract: The present invention provides a quick install lockset mechanism having a semipermanent mechanical connection between an interior lock assembly and an exterior lock assembly. The exterior lock assembly includes a pair of threaded fasteners extending through a preformed hole in a door, and the interior lock assembly includes a rose liner configured to rotatably engage the fasteners to connect the interior and exterior lock assemblies. The interior lock assembly rose liner includes a pair of raised contoured portions having openings for receiving the fasteners and ramps for guiding the fasteners to the openings. In addition, the interior lock assembly includes a knob insert and a turnpiece guide. The knob insert is disposed in the knob and the turnpiece guide is removably disposed in the knob insert. A turnpiece is disposed in the turnpiece guide and is thereby aligned with an operating member extending from a lock cylinder in the exterior lock assembly.

  • Patent number: 5810402
    Abstract: An interconnected lock is disclosed which can be used in applications which have differing center distances. A rack is located between the lower operator assembly and the upper deadbolt for engaging a pinion which will release the deadbolt. This pinion can be vertically located at a position to receive the drive spindle of the deadbolt. A second pinion which is secured to the turn lever for the deadbolt is secured to the faceplate. These pinions cooperate with adjacent width portions of the rack enabling the faceplate to operate with different center distances.
