  • Positive action lock for sliding windows
    Patent number: 7676990
    Abstract: A sliding window having a pair of sashes with a latch mechanism on the meeting rail of one of the sashes for latching the sashes together. To open the window, the latch mechanism is disengaged by grasping a finger grip on a latch handle to retract a latch bolt. As one or more of the sashes is slid to open the window and the latch mechanism clears the meeting rail of the other sash, a trigger cam rotates so that a portion extends outward from the latch mechanism and another portion releases a spring tab to engage and hold the latch bolt in the retracted position. When the window is closed, the outwardly extending portion of the trigger cam contacts the meeting rail of the other sash, causing the trigger cam to rotate in the opposite direction and releasing the latch bolt.
