The lowering of the shaft body 45 and the rotation of the connecting members 67 and 74 cause the sash 6 to be 7 is rotated in a manner of extending outward in the direction of the building; the opening of the opening 4 is released by the sash 6 and the opening 4 is opened; and the opening 4 is forcibly opened by the sash 6 to be fully opened by the sash 6 by the electric motor 154 Actuating to move the mounting table 93 downward, the projection 132 is in contact with the other end 122 of the pawl member 112 and pressing the other end 122; the projection 132 is held by the other end 122 of the pawl member 112. When pressed, the pawl member 112 is rotated in the direction R62 against the elastic force of the coil spring 124. As shown in FIG. 8, one end portion 82 of the pawl member 112 is immersed outside the up-and-down direction guiding passage 52; by the pawl member 112 One end portion 82 releases the constraint of the shaft body 45 The shaft main body 45 is freely movable in the upper and lower direction guiding passages 52 of the inclined guiding passage 53 and the continuous inclined guiding passage 53; and after the one end portion 82 of the pawl member 112 is out of the vertical guiding passage 52, the electric motor 154 is caused. The action stops.

As shown in FIG. 8, in the case where one end portion 82 of the pawl member 112 is located outside the up-and-down direction guiding passage 52, the shaft main body 45 is along the inclined guiding passage 53 and the continuous inclined guiding passage in the range of the upper end 54 and the surface 97. 53 is freely movable in the upper and lower direction guiding passages 52, so that the wind pressure from the outside of the building 2 to the inside of the building 3 does not act on the sash 6, the sash 6 is inclined with respect to the opening 4 at the maximum opening degree, on the other hand The inclination of the wind pressure corresponding to the wind pressure is inclined with respect to the opening 4, so that the building 3 is naturally ventilated.

In the case where the opening and closing of the opening 4 corresponding to the wind pressure is released by the sash 6, and the opening 4 is forcibly closed by the sash 6, the electric motor 154 is operated in the opposite direction to the above, and the mounting table 93 is reversed from the foregoing. Moving upward; moving over the mounting table 93, releasing the contact of the other end portion 122 of the pawl member 112 with the protrusion 132, and rotating the pawl member 112 in the direction R61 by the elastic force of the coil spring 124; In the rotation of the direction R61 of the member 112, one end portion 82 of the pawl member 112 is again present in the up-and-down direction guiding passage 52, and on the other hand, the surface 97 of the mounting table main body 94 is moved by the upper side of the mounting table 93. When the shaft main body 45 is in contact with the upper side of the mounting base main body 94, the shaft main body 45 is moved upward along the vertical direction guiding passage 52; and the sash 6 is moved over the shaft main body 45 to be pulled into the building. When the direction is rotated, the opening 4 is closed by the sash 6; when the sash 6 starts to close the opening 4, the connecting member 67 is rotated around the axis O3 and rotated in the R3 direction in the vertical plane. Table 66 along The guide rail 36 is moved downward, and the connecting member 74 is rotated in the R5 direction in the vertical plane centering on the axial center O5 of the shaft member 73. Further, the upper side of the sliding member 91 is actuated by the opposite operation of the electric motor 154. Moving above the mounting main body 94 by the movement, the shaft main body 45 guides the passage 52 in the up and down direction and then moves upward along the inclined guiding passage 53; the shaft main body 45 moves upward along the inclined guiding passage 53. The shaft main body 45 is moved from the small slit 103 to the large slit 104, and the surface 97 of the mounting main body 94 is brought into contact with the shaft main body 45 that has moved to the large slit 104; the shaft 97 is moved over the surface 97 of the mounting main body 94 to make the shaft The main body 45 moves upward; when the upper side of the shaft main body 45 is moved by the upper surface 97 of the mounting main body 94, the hook 157 is hooked to the protrusion 156; and after the hook 157 is hooked to the protrusion 156, The sash 6 is placed at the position where the opening 4 is completely closed as shown in FIG. 1, and the operation of the electric motor 154 is stopped.

In the case where the sash 6 is forcibly closed by the opening 4, when one end portion 82 of the pawl member 112 is reappeared in the up-and-down direction guiding passage 52, even if the shaft main body 45 is located at one end portion 82 of the pawl member 112 Between the upper ends 54 of the inclined guide passages 53, the pawl members 112 are also rotatable in the direction R62, so that the pawl members 112 are brought into contact with the shaft main body 45 and pressed against the one end portion 82 under the movement thereto. The shaft main body 45 is rotated in the direction R62. As a result, the shaft main body 45 can be moved upward on the surface 97 or 99 of the mounting base main body 94. On the other hand, the one end portion 82 is prevented from appearing in the vertical direction guiding passage 52 by the projection 125. Or, as a result of the pawl member 112 in the inclined guide passage 53 being rotated in the direction R61 or more, if the end portion 82 of the pawl member 112 and the mounting table main body 94 appear in the up-and-down direction guiding passage 52 or the inclined guiding passage 53 When the shaft main body 45 is disposed between the faces 97 or 99, the shaft main body 45 cannot be moved between the one end portion 82 and the upper end portion 54 of the inclined guide passage 53.

When the sash 6 is completely closed by the opening 4, even if a pressure difference is generated inside and outside the building, the sash 6 can maintain the state in which the opening 4 is completely closed by the lock mechanism 13, and the sealing member 24 is pressed by the sealing pressing member 39 to open the opening. 4 Forced to completely shut down.

As described above, in the window closing device 1, the lower side of the movable table 81 when the sash 6 is moved from the position where the opening 4 is closed to the position of the opening 4 is moved, and the one end portion 82 is brought into contact with the shaft member 43 to make the shaft member. The pawl mechanism 83 that moves downward along the guide passage 44 has an end portion 82 that is free to the guide passage 44, and on the one hand prohibits the shaft member 43 from passing through the guide passage 44 through the one end portion 82, The side member 82 is allowed to appear in the guiding passage 44 along the guiding passage 44, and the one end portion 82 is prevented from obstructing the shaft member 43 in the case of being out of the guiding passage 44. The guide passage 44 moves upward and downward; the immersion mechanism 84 immerses one end portion 82 of the pawl mechanism 83 into the guide passage before the sash 6 moves under the movable table 81 to the position where the opening 4 is fully opened. 44; the movable table 81 moves upward while moving the sash 6 from the position of the opening 4 to the position where the opening 4 is closed, and comes into contact with the shaft member 43 to move the shaft member 43 along the guide passage 44, and Making the movable table 81 The movable table linear motion mechanism 85 is vertically moved in the vertical direction. Therefore, the operation of the movable table linear motion mechanism 85 can switch the opening and closing of the opening 4 by the sash 6 based on the wind pressure, and the opening 4 by the sash 6 Mandatory opening and closing.
