WINDOW STRUCTURE FOR EMERGENCY EXIT

PURPOSE:To form an alternate approach port sewing as an emergency exit immediately as necessary by releasing a lock device from the outside of a window frame so as to open a window frame for emergency exit largely. CONSTITUTION:A stationary frame 13 is mounted in parallel to a window for emergency exit 11, onto which a lock device 12 is installed so as to release the lock device easily from the outside of the window frame 11 for emergency exit at the time of emergency. The window frame 11 for emergency exit is rotated outwards largely around one edge 11a of its vertical frame. A stopper device 16 is mounted between a screen 14 for ventilation and lighting and the window frame 11 for emergency exit to inhibit the screen 14 for ventilation and lighting from opening except for only a prescribed maximum dimension. By installing the screen 11 for ventilation and lighting whose rotational angle is limited within a safety angle on the frame body 11 for emergency exit, it is possible to prevent an infant from falling down.
