a connector disposed within the channel and having a first end connected to one of the pair of latch bolts and a second end connected to the other of the pair of latch bolts, wherein the connector further comprises an enlarged region received by the pair of generally opposed recesses;
an actuator operably connected to the rotor, the actuator having a locked position wherein the rotor is adapted to engage the keeper, the actuator being moveable to an unlocked position wherein the rotor is adapted to disengage from the keeper, and being further moveable to a tiltable position wherein the rotor rotates to wind the connector thereby retracting the latch bolts from the master frame.
7. The integrated tilt-latch/sash lock assembly of claim 6 wherein the connector comprises a cord and the enlarged region comprises a knot in the cord, the knot being received by the pair of generally opposed recesses.
8. An integrated tilt-latch/sash lock assembly for a sash window assembly, the sash window assembly having an upper sash window and a lower sash window slideable within a master frame, the tilt-latch/sash lock assembly comprising:
a keeper configured to be connected to the upper sash window;
a rotor assembly configured to be supported by the lower sash window having a rotor for engaging the keeper;
a spool configured to be supported by the lower sash window and operably connected with the rotor, the spool having a channel having a base;
a protrusion extending into the channel defining a bottom wall in spaced relation to the channel base;
a pair of latch bolts configured to be supported by the lower sash window and each latch bolt adapted to engage the master frame;
a connector disposed within the channel and having a first end connected to one of the pair of latch bolts and a second end connected to the other of the pair of latch bolts, wherein a portion of the connector is received between the bottom wall and the base;
an actuator operably connected to the rotor, the actuator having a locked position wherein the rotor engages the keeper, the actuator being moveable to an unlocked position wherein the rotor is disengaged from the keeper, and being further moveable to a tiltable position wherein the rotor rotates to wind the connector thereby retracting each latch bolts from the master frame.
9. The integrated tilt-latch/sash lock assembly of claim 8 wherein the channel further has a pair of opposed recesses that each receive an enlarged portion of the connector.
10. An integrated tilt-latch/sash lock assembly for a sash window assembly, the sash window assembly having an upper sash window and a lower sash window slideable within a master frame, the tilt-latch/sash lock assembly comprising:
