Claims

[Claim for Utility Model Registration] When closing the window, the ratchet wheel, which is rotatably supported integrally with the winding drum on the mounting body, is held in the locking position by contacting the outer periphery of the push button. In a state in which the locking pawl of the oscillator is locked to allow rotation of the winding drum only in the winding direction, the winding drum is rotated and attached to the window frame in the window opening direction. Winding up the wire stretched between the shoji and moving the shoji in the window closing direction, and stopping the drive of the winding drum by locking the locking pawl to the ratchet wheel. At the same time, the rotation of the winding drum in the unwinding direction is locked, the unwinding of the wire is stopped, and the shoji is held so that it cannot move in the opening direction, and when opening the window, the swinging body is , by pushing the push button into a recess formed on its outer periphery, the locking pawl is disengaged from the ratchet wheel and held in an unlocked position that allows rotation of the winding drum in the unwinding direction. Then, while letting out the wire, the shoji is moved in the window opening direction, and after the window is opened, the winding drum is started to rotate in the winding direction, so that the ratchet wheel returns the swinging body. By pressing the pawl, the rocking body is removed from the recess against the spring force, and at the same time is locked to the outer periphery of the protruding push button by another spring force, thereby achieving the lock operation position. In the opening/closing operation device for a smoke exhaust window, the drive shaft having an engaging portion protruding on the outer periphery of the mounting body is rotatable in a direction perpendicular to the advancing and retreating direction of the push button. At the same time, a pressing body is supported, which swings due to the engagement of the engaging portion as the drive shaft rotates in one direction, and presses the push button in the pushing direction, and is attached to the drive shaft and to the window frame. A rotary drive body such as a gear that reciprocates an operating member such as a geared cable connected to the provided locking device between a locking operating position and a locking release position is connected so as to be able to rotate in conjunction with the drive shaft. A smoke evacuation window opening/closing device featuring:
