WINDOW OPENING/CLOSING LOCKING DEVICE

PROBLEM TO BE SOLVED: To open/close a window by remote operation, and lock and release the window interlockingly with closing and opening of the window. SOLUTION: A window 3 is always energized in the opening direction by a window push rod 4, and the window 3 is closed by tension imparted to a wire 5. The window 3 is provided with a lever 7 locking or releasing by rotating operation. A driving arm 10 for rotatory-operating the lever 7 is rotatably fitted to a frame body 2. The driving arm 10 is energized onto the lock release side by an arm push rod 11. The tension of the wire 5 is imparted to the driving arm 10 by a tension imparting means 12. When the tension of the wire 5 is released, the driving arm 10 rotates the lever 7 onto the release side, and the window 3 is opened by the action of the window push rod 4 after lock is released. When tension is imparted to the wire 5, on the other hand, the window 3 is closed, and the driving arm 10 is rotated onto the lock side to lock the window 3.
