ABSTRACT:
A window lock with an automatic latch retention mechanism and an associated method of securing adjustable frame members of a window are provided. The lock generally includes a housing that can be secured to a first window frame member, a latch member slidably mounted in the housing, a rotatably handle configured to actuate the latch member, and a retention mechanism configured to automatically retain the latch member in the retracted position until the first and second window frame members are relatively adjusted to a closed configuration. The lock can automatically adjust to a locked configuration when the window is closed and remain in an unlocked configuration while being adjusted. The rotatable handle, which can be used to retract the latch member, is configured to provide an indication of the configuration of the lock so that a user can easily identify whether the lock is locked or unlocked.
