<p>A sliding window system can be equipped with a latch or lock mechanism. The lock mechanism can include a lock base mounted on a sliding sash of a window assembly opposite a keeper. The latch bolt of lock mechanism can be received in the keeper to latch the sashes together. A trigger is operably coupled with the latch bolt. To open the window, the lock mechanism is disengaged from the keeper by grasping a pull handle and pullin g outwardly away from the window. As a result, the bolt moves to a retracted position within the lock base and a portion of the trigger extends out of the lock base, with the window capable of movement into an open position. When closing the window, the trigger contacts the keeper, releasing the bolt under the bias of a spring into the keeper, thus locking the window.</p> |
