It is a rubber drainer that contacts the vertical frames 6 and 7.

  In this configuration, as shown in FIG. 4, when the upper screen 13 is opened from the closed state, the handle 27 is rotated to move the slide frame 34 in the direction of the arrow X1 in FIG. Move in the direction. As a result, the arm 44 rotates about the shaft 43 as indicated by the arrow R1, and the upper shoji 13 is pushed by the arm 50 and rotates and opens as indicated by the arrow R2. When the handle 27 is rotated in the opposite direction, the upper shoji 13 is closed by the movement in the opposite direction. In the case of the shoji 14, in FIG. 7, when the slide frame 34 </ b> A is moved in the direction of the arrow X <b> 2 by the rotation of the handle 28, that is, from the right side to the left side on the paper surface, the arm 44 </ b> A is indicated by the arrow R <b> 3 centering on the shaft 43 </ b> A. The lower shoji 14 is pushed by the arm 50A and is rotated and opened as indicated by an arrow R4.

  In this state where the upper and lower shojis 13 and 14 are opened upside down, as shown by the arrow S1 in FIG. 1B (viewed from the outdoor side), the wind blowing from the right side on the paper surface is The room is blocked by the upper shoji 13 and enters the room through the upper opening 66, and the air that has entered the room exits through the lower opening 67 as indicated by an arrow S2. On the contrary, as shown by the arrow S3, the wind blowing from the left side on the paper surface is blocked by the lower shoji 14 and enters the room through the lower opening 67, and the air that has entered the room passes through the upper opening 66 through the arrow S4. Go outside as shown. Such air flow improves ventilation efficiency regardless of the direction of air flow.

  In the ventilator 2 of the present embodiment, the first operation unit 15 and the second operation unit 16 that open and close the upper and lower shojis 13 and 14 are provided in the intermediate frame 10 that partitions the upper window and the lower window, respectively. Further, not only when opening and closing the upper shoji 13 but also when opening and closing the lower shoji 14, there is no need to bend down and operate the operation unit, and the operability is improved. Moreover, since not only the 1st operation part 15 which opens and closes the upper shoji 13 but the 2nd operation part 16 which opens and closes the lower shoji 14 was also provided in the intermediate | middle frame 10, the 2nd operation part 16 is extremely lower position. In addition, the screen doors 20 and 21 do not need to be roll screen doors or inward-opening screen doors, and can be fixed screen doors as shown in the figure.

  In addition, an accommodation space 10f (see FIGS. 5 and 8) provided in the intermediate frame 10 for passing the arms 41A, 44A, and 50A, which are constituent members of the coupling mechanism 24, is sealed by the sealing materials 60 to 62, so Even if rainwater or the like is likely to enter, rainwater entering from between the side of the lower shoji 14 and the frame efficiently seals the accommodation space 10f and enters the room. This can be prevented and the airtightness is improved.

  That is, when an unconventional configuration in which the operation units 15 and 16 having an operator handle are attached to the intermediate frame 10 as in the present embodiment is adopted, as shown by an arrow T in FIG. Water that enters between the lower ends of the shoji 13 is prevented from entering the room by the vertical plate portion 10 g on the indoor side of the intermediate frame 10. However, rainwater that has broken through the draining material 63 or the like with strong wind or rainwater that enters between the side portion of the lower shoji 14 and the vertical frames 6 and 7 can be used when the seal material 61 and 62 are not provided. Water leaks from the space between the indoor side surface and the intermediate frame 10 to the indoor side through the opening 10d (see FIGS. 5 and 8).

  However, the sealing materials 60 to 62 can prevent rainwater and the like from entering from the side portion of the lower shoji 14 by sealing the housing space 10f of the arms 41A, 44A, 50A of the coupling mechanism 25 so as to surround the housing space 10f. . That is, as shown in FIG. 12, in the state where the lower shoji 14 is in pressure contact with the sealing materials 60 to 62 and closed, the space upper side sealing material 60 and the space lower side sealing material 61 each having a cylindrical cross section are respectively provided. As shown by arrows D and U, it is deformed so as to expand in the vertical direction (the surface direction of the shoji), and is pressed against the upper end and the lower end of the space side seal material 62, respectively. For this reason, the flow of the external air and rain water which go to the accommodation space 10f from the side part of the shoji 14 as shown by arrow S can be stopped reliably, and air-water tightness can be ensured.

  Moreover, although the ventilation apparatus of this invention can also be comprised as a single window so that it may mention later, the sealing structure of this Embodiment seals the accommodation space 10f of the connection mechanism 25 of the lower window of a step window. Since the ventilation device is configured by adopting the structure, even in the case of a high-stage window such as the window 2 connected to the fixed window 1 provided in the building as in the present embodiment, The position of the operation unit 16 of the shoji 14 is not lowered, and therefore, the handle window of the operation unit 16 is not disturbed by a load or the like placed on the floor surface, and the stepped window capable of improving the operability has a sealing property. Can be realized as a high-stage window.

  Further, since the operation handles 15 and 16 are provided with the operator handles 27 and 28 as in this embodiment, the shoji can be opened and closed with a relatively small operation force.

  Further, as in the present embodiment, the fixed screen doors 20 and 21 are provided on the upper frame portion 11 and the lower frame portion 12 respectively, so that the screen doors 20 and 21 are opened and closed when the shoji screens 13 and 14 are opened and closed. Therefore, a ventilation device with good operability and design can be provided.

  FIG. 13 (A) shows another embodiment of the ventilator according to the present invention, which is realized as a fitting window that cannot open and close the upper window 13 </ b> A partitioned by the intermediate frame 10. In this case, only the lower shoji 14 constitutes a ventilation device, and the intermediate frame 10 serves as the upper frame for the ventilation device. FIG. 13B is an example in which the ventilation device is configured as a single window, and the frame of this single window is composed of an upper frame 3A, a lower frame 4A, and left and right vertical frames 6A, 7A. 14A is mounted in the frame. In the case of the ventilator having a single window structure in the example of FIG. 13B, the upper frame 3A is not so high, the hand can easily reach the operation unit 16, and the lower frame 4A is low. As a result, operability can be improved.

  When practicing the present invention, various mechanisms other than the configuration shown in the above embodiment can be adopted as the mechanism for converting the rotation of the handles 27 and 28 of the operation units 15 and 16 into the opening and closing of the shojis 13 and 14. It is also possible to employ a mechanism that opens and closes by moving the slide frame left and right instead of turning the handles 27 and 28. Further, when the present invention is configured as a stepped window, it can be configured not only as a window that opens and closes upside down but also as a window that opens in the same direction. In addition, when implementing this invention, a various change and addition are possible in the range which does not deviate from the summary of this invention.
