  • Publication number: 20050044797
    Abstract: A window structure is provided which may be used as a rear window in a pick-up truck or the like. In certain example embodiments, the window structure includes a slidable window panel or sheet located between a pair of fixed window panels or sheets. The slidable window panel may be approximately flush with the fixed panels when in the closed position, but not in the opened position. In certain example embodiments, the movable window sheet or panel may be opened by a user actuating a latch assembly which allows one or more spring loaded pins to be moved from a locked to an unlocked position(s). When the spring loaded pins move into an unlocked position as the latch assembly is actuated, the movable window panel can be moved slightly toward the vehicle interior and then slid laterally in respective tracks in order to open the same.
