Abstract:
1. An openable roof window, comprising: a base frame defining an opening and configured to be secured to a roof; a guide rail mounted to the base frame; a movable window panel configured to be slidable along the guide rail in an opening direction to open the opening and in a closing direction to close the opening, the movable window panel further configured to be tiltable relative to the base frame; a first sliding member having a pin and configured to be driven by a drive device to slide along the guide rail; a stay fixedly secured to the movable window panel and having a cam groove formed therein, the cam groove including a first end portion and a second end portion opposite the first end portion; a lock member configured to be in a lock position where the lock member prevents sliding of the movable window panel along the guide rail when the pin is at a position in the cam groove other than the second end portion of the cam groove and configured to be moved to an unlock position where the lock member permits the sliding of the movable window panel along the guide rail when the pin is in the cam groove at the second end portion of the cam groove, the lock member having a lock cam groove formed therein such that the pin engages the lock cam groove to move the lock member between the lock position and the unlock position as the first sliding member moves relative to the lock member along the guide rail; wherein the lock cam groove, the cam groove and the pin form an engagement structure that selectively engages the first sliding member with the movable window panel such that the first sliding member and the movable window panel are unmovable relative to each other in the opening direction along the guide rail when the lock member is in the unlock position, and wherein the engagement structure allows the first sliding member to move relative to the movable window panel in the opening direction along the guide rail when the lock member is in the lock position; and wherein the cam groove of the stay engages the pin of the first sliding member and has a shape defined such that, when the engagement structure does not engage the first sliding member with the movable window panel, the movable window panel is caused to tilt relative to the base frame as the first sliding member moves relative to the stay as a result of the first sliding member sliding along the guide rail.
