ABSTRACT:
A pivotable window which is moved between locked and opened position by means of a single operating handle. The window comprises a window frame, a window screen, an endless belt mounted within the window frame, a plurality of locking means, and an operating mechanism. The operating mechanism is connected to both the endless belt and the locking means. Moving the operating mechanism moves the endless belt; and this, in turn, moves the locking means between a locking position, for securely holding the window screen closed, and an unlocking position, disengaged from the window screen. Further movement of the operating mechanism moves the window screen between the closed position and an open position.
