  In the shoji support mechanism 11, the rotation axis O <b> 2 is more than the center of gravity G of the shoji 6 so that a rotation moment that opens the opening 4 is generated in the shoji 6 by the dead weight of the shoji 6 until the maximum opening with respect to the opening 4. The shoji 6 is located on the upper side and the outside 2 side of the building. Therefore, the shoji 6 is in a naturally ventilated state, and the air flow through the opening 4 does not occur or the inside of the building 3 side is directed to the outside 2 side of the building. When airflow occurs, the airflow is stationary at the maximum open position with respect to the opening 4, while in the case of natural ventilation, when the airflow from the outside 2 side to the inside 3 side of the building occurs Depending on the magnitude of the rotational moment in the direction of closing the opening 4 due to the wind pressure based on the pressure and the rotational moment in the direction of opening the opening 4 based on the dead weight of the shoji 6, the passage through the opening 4 for the air flow is narrowed or expanded.

By rotating the members 67 and 74, the shoji 6 is rotated so as to protrude in two directions outside the building as shown in FIG. 7 to release the opening 4 by the shoji 6 to open the opening 4. The protrusion 132 is brought into contact with the other end portion 122 of the ratchet member 112 by the downward movement of the mounting base 93 by the further operation of the electric motor 154 immediately before the opening of the mouth 4 is forcibly opened. The ratchet member 112 is rotated in the direction R62 against the elastic force of the coil spring 124 by pressing by the projection 132 of the other end 122 of the member 112, and as shown in FIG. 8, the vertical direction of the one end 82 of the ratchet member 112 The shaft body 45 is released from the guide path 52, the restraint of the shaft body 45 by the one end 82 of the ratchet member 112 is released, and the shaft body 45 can be freely moved in the vertical guide path 52 following the tilt guide path 53 and the tilt guide path 53. After the immersion of the one end 82 of the ratchet member 112 outside the vertical guide path 52, the operation of the electric motor 154 is stopped.

  As shown in FIG. 8, when the one end portion 82 of the ratchet member 112 is located outside the vertical guide path 52, the shaft main body 45 is within the range of the upper end 54 and the surface 97 and the inclined guide path 53 and As a result of being able to move freely along the vertical guide path 52 that follows the inclined guide path 53, the shoji 6 is opened to the maximum with respect to the opening 4 as long as the wind pressure from the outside 2 to the inside 3 does not act on the shoji 6. While it is inclined with a degree, it will be inclined with the opening degree with respect to the opening 4 according to the wind pressure acting on it, and thus the inside 3 of the building is naturally ventilated.

  When the opening / closing of the opening 4 according to the wind pressure by the shoji 6 is released and the opening 4 is forcibly closed by the shoji 6, the electric motor 154 is operated in reverse to the above and the mounting base 93 is set in reverse to the above. The ratchet member 112 is moved upward, the contact of the other end 122 of the ratchet member 112 with the protrusion 132 is released by the upward movement of the mounting base 93, and the ratchet member 112 is rotated in the direction R 61 by the elastic force of the coil spring 124. One end 82 of the ratchet member 112 reappears in the vertical guide path 52 by rotation in the direction R61, while the mounting base body is brought into contact with the shaft main body 45 of the surface 97 of the mounting base body 94 by the upward movement of the mounting base 93. The shaft body 45 is moved upward along the vertical guide path 52 with the upward movement of 94, and is rotated so that the shoji 6 can be pulled in three directions in the building by the upward movement of the shaft body 45. The closing of the opening 4 by the shoji 6 is started, and the opening of the opening 4 by the shoji 6 is started, and the movable base 66 is moved along the guide rail 36 while rotating the connecting member 67 in the R3 direction around the axis O3 in the vertical plane. The connecting member 74 is moved downward, and the connecting member 74 is rotated in the R5 direction in the vertical plane around the axis O5 of the shaft member 73. Further, the mounting base body 94 is moved through the upward movement of the sliding member 91 by the reverse operation of the electric motor 154. The shaft body 45 is moved upward along the vertical guide path 52 and subsequently along the inclined guide path 53, and the shaft body 45 is moved upward along the inclined guide path 53 from the small notch 103 of the shaft body 45 to the large size. The shaft body 45 is moved by moving the surface 97 of the mounting base body 94 in contact with the surface 97 of the mounting base body 94 in contact with the shaft main body 45 transferred to the large notch 104. Upward When the shaft body 45 is moved upward by the upward movement of the surface 97 of the mounting base 94, the hook 157 is hooked on the protrusion 156, and the hook 6 is hooked on the protrusion 156. The operation of the electric motor 154 is stopped by arranging the opening 4 shown in FIG.

  In the case where the opening 4 is forcibly closed by the shoji 6 and the one end 82 of the ratchet member 112 is reappeared in the vertical guide path 52, the shaft body 45 is inclined with respect to the one end 82 of the ratchet member 112. Even if it is located between the upper end 54 of the guide path 53, the ratchet member 112 is rotatable in the direction R62. As a result of being touched by the shaft main body 45 and pressed by the shaft main body 45 and rotated in the direction R62, the shaft main body 45 can be moved upward on the surface 97 or 99 of the mounting base main body 94, while the one end 82 is guided in the vertical direction guide path. As a result of the protrusion 125 prohibiting further rotation of the ratchet member 112 that has appeared in 52 or the inclined guide path 53 in the direction R61, the vertical guide path 52 or the tilt direction When the shaft main body 45 is arranged between the one end portion 82 of the ratchet member 112 that has appeared in the guide path 53 and the surface 97 or 99 of the mounting base main body 94, the shaft main body 45 is inclined between the one end portion 82 and the inclined guide. It cannot move between the upper end 54 of the path 53.

  When the opening 4 is completely closed by the shoji 6, the shoji 6 is maintained in a state in which the opening 4 is completely closed by the key mechanism 13 even if a pressure difference occurs inside and outside the building, and the seal pressing member 39 presses the seal member 24. Thus, the opening 4 is forcibly completely closed.

  As described above, in the window opening and closing device 1, the shaft member 43 is brought into contact with the shaft member 43 at the one end 82 by the downward movement of the movable table 81 when the shoji 6 is moved from the position where the opening 4 is closed to the position where the opening 4 is opened. 43 is moved downward along the guide path 44, and the ratchet mechanism 83 has one end portion 82 that can be moved into and out of the guide path 44, and an axis along the guide path 44 through the one end portion 82. While prohibiting the passage of the member 43 upward, the one end 82 is caused to appear in the guide path 44 so as to allow the shaft member 43 to pass downward along the guide path 44 and is immersed outside the guide path 44. In this case, the movement of the shaft member 43 along the guide path 44 in the upward and downward direction is not hindered by the one end portion 82, and the immersion mechanism 84 fully opens the opening 4 by the downward movement of the movable base 81. Shoji 6 arrives at the position Immediately before, the one end 82 of the ratchet mechanism 83 is immersed outside the guide path 44, and the movable base 81 moves the shoji 6 from the position where the opening 4 is opened to the position where the opening 4 is closed. The shaft member 43 is moved along the guide path 44 in contact with the shaft member 43 by upward movement, and includes a movable table linear movement mechanism 85 that linearly moves the movable table 81 in the vertical direction. Therefore, the opening / closing of the opening 4 by the shoji 6 based on the wind pressure and the forcible opening / closing of the opening 4 by the shoji 6 can be switched by the operation of the movable table linear movement mechanism 85.
