Patent ID: 8347678

Claim:
A rekeyable lock cylinder assembly, comprising: (a) at least one lock cylinder, each lock cylinder including: a cylinder body with a longitudinal axis; a locking bar disposed in the cylinder body for movement transverse to, and rotationally about, the longitudinal axis; a plug assembly disposed in the cylinder body and being rotatable about the longitudinal axis, the plug assembly having a lock face with a tool receiving aperture, and having a proximal end and a distal end separated from the proximal end with the proximal end being located nearest to the lock face; a plurality of pins and a corresponding plurality of racks disposed in the plug assembly, the plurality of racks being configured to be selectively engaged with the plurality of pins; and a first member coupled to the plurality of racks, the first member being moveable in response to application of a force by a tool received through the tool receiving aperture, the first member being configured to simultaneously disengage all of the plurality of racks from the plurality of pins in response to the movement of the first member; and (b) a mortise lock adapter, including: a housing configured with a longitudinal cavity for receiving the cylinder body of the at least one lock cylinder, the at least one lock cylinder being mounted to the housing; and a mortise lock actuator coupled to the plug assembly of the at least one lock cylinder, wherein the at least one lock cylinder comprises a first lock cylinder and a second lock cylinder, and wherein: the housing of the mortise lock adapter has a first end spaced apart from a second end along the longitudinal cavity; the cylinder body of the first lock cylinder is received into the longitudinal cavity of the housing at the first end; the cylinder body of the second lock cylinder is received into the longitudinal cavity of the housing at the second end; the mortise lock actuator includes a split driver and a cam, the cam having an opening that receives the split driver in a sliding relationship, the split driver having a first drive portion rotatably coupled to a second drive portion; the distal end of the plug assembly of the first lock cylinder being configured and positioned to drivably engage the first drive portion of the split driver; and the distal end of the plug assembly of the second lock cylinder is configured and positioned to drivably engage the second drive portion of the split driver, wherein: the longitudinal cavity of the housing defines a co-axis of rotation corresponding to the longitudinal axis of the plug assembly of the first lock cylinder and to the longitudinal axis of the plug assembly of the second lock cylinder; the cam has direct radial support relative to the co-axis provided only by the split driver; and the split driver has direct radial support relative to the co-axis provided only by the distal end of the plug assembly of the first lock cylinder and the distal end of the plug assembly of the second lock cylinder.
