As shown in FIG. 2, the side member 25 is provided with an insertion hole 34 of the rotary shaft 2 at an eccentric position upward in the upper panel 1 a and downward in the lower panel 1 b, and a bearing on the back side of the insertion hole 34. The bearing member 35 having the interior is screwed, and the tip end portion of the rotary shaft 2 is rotatably received by the bearing member 35. The gap between the collar frame 4 and the side member 25 is closed by a fin-like tight member 52 formed of rubber.

  In the state where the horizontal axis rotary panels 1a and 1b are closed, as shown in FIG. 1, the drooping portion 7 of the upper horizontal axis rotary panel 1a adjacent to the upper and lower sides and the rising portion 6 of the lower horizontal axis rotary panel 1b However, it overlaps with the gap 8 in the indoor / outdoor direction, and the horizontal connecting member 5 laid between the left and right eaves frames 4, 4 is inserted into the gap 8 between the rising portion 6 and the hanging portion 7. ing. Therefore, when the horizontal axis rotary panels 1a and 1b are closed, the horizontal connecting member 5 cannot be seen from the indoor side and the outdoor side.

The horizontal axis rotary panels 1a and 1b have the rotary axis 2 provided at a position eccentrically upward or downward with respect to the middle in the vertical direction of the panel, and the weight 3 is attached in the eccentric panel. Although it opens and closes naturally under the wind pressure, it also has an opening and closing mechanism 36 that forcibly opens and closes the plurality of horizontal axis rotary panels 1a and 1b. Hereinafter, the opening / closing mechanism 36 will be described.
As shown in FIG. 2, a rail 49 is attached to the prospective surface on the indoor side of the eaves frame 4 along the longitudinal direction, and the slide bar 9 engages with the rail 49 and moves up and down along the eaves frame 4. It is slidably attached to. On the slide bar 9, a pressing projection 11 made of a roller that is supported by a horizontal axis is attached toward the outdoor side. As shown in FIG. 1, as many pressing protrusions 11 are provided as the number of the horizontal axis rotary panels 1a and 1b so as to be positioned in the vicinity of the rotary axis 2 of each horizontal axis rotary panel 1a and 1b.
As shown in FIGS. 1 and 2, a contacted member 37 with which the pressing protrusion 11 abuts is located at the side end of the indoor side surface of the horizontal axis rotary panels 1 a and 1 b in the vertical direction near the height of the rotary shaft 2. It is installed in the direction of. The contacted member 37 has a flat portion 38 and a substantially semicircular protruding portion 10 continuous to the lower end of the flat portion 38, and the protruding portion 10 is positioned slightly below the rotating shaft 2.
An operation box 39 is attached to the side surface of the vertical body 17 as shown in FIGS. The operation box 39 includes a rack 40 that is movable in the vertical direction and a gear 41 that meshes with the rack 40, and the rack 40 is connected to the slide bar 9 by a connecting member 42. A handle 43 is attached to the rotation shaft of the gear 41. The gear 41 rotates within a range of 90 ° from the state in which the handle 43 is directed downward until the handle 43 becomes horizontal toward the indoor side.

When the horizontal axis rotary panels 1a and 1b are closed, the slide bar 9 is in the highest position, and the pressing projection 11 is near the upper end of the flat part 38 above the rotary axis 2 as shown in FIG. Accordingly, the horizontal axis rotary panels 1a and 1b are held in a closed state.
When the handle 43 is rotated to the indoor side, the slide bar 9 slides downward together with the rack 40, and, as shown in FIG. 1a and 1b open simultaneously in unison. Thereafter, in the absence of wind, the horizontal axis rotary panels 1a and 1b close the panel due to a moment to rotate in the direction in which the panel is opened by the dead weight above the rotary axis 2 and the dead weight below the rotary axis 2. Stops at the position where the moment to rotate is suspended. As shown in FIG. 7B, a stopper 44 is attached to the vertical body 17, and the maximum opening angle of the horizontal axis rotary panels 1 a and 1 b is regulated by the stopper 44. When the handle 43 is rotated to the outdoor side and returned to the original position, as shown in FIG. 7C, the slide bar 9 slides upward, and the pressing projection 11 abuts against the flat portion 38 and pushes up. The horizontal axis rotating panels 1a and 1b are interlocked and closed simultaneously.

When the slide bar 9 is slid downward as described above and the horizontal axis rotary panels 1a and 1b are opened, the wind 45a is directed from the outdoor side toward the indoor side as shown in FIG. When a positive pressure is applied to the horizontal axis rotation window 16, the first to seventh horizontal axis rotation panel (upper panel) 1 a from the top has a lower area than the upper axis than the rotation axis 2. Because the wind pressure generates a force in the direction of closing the panel, it closes naturally under the wind pressure. The lowermost horizontal axis rotation panel (lower panel) 1b is kept open because the area above the rotation axis 2 is larger than the area below the lower axis, so that a force in the direction of opening the panel is generated by wind pressure. Therefore, cool outdoor air is taken into the room from the bottom of the window through the opened lower panel 1b.
On the other hand, as shown in FIG. 8B, when the wind 45b blows away from the building and negative pressure is applied to the horizontal axis rotary window 16, the upper panel 1a has an area below the rotary axis 2 on the upper side. Since the force in the direction of opening the panel is generated by the wind pressure because the area is larger than the area, the lower panel 1b remains open, and the area above the rotating shaft 2 is wider than the area below the lower shaft 1b. Since a force in the closing direction is generated, it closes naturally under wind pressure. Therefore, warm air in the room is discharged from the upper part of the window through the opened upper panel 1a.
In the windless state, as shown in FIG. 8 (c), the upper panel 1a and the lower panel 1b are both open, and due to the difference in the air density due to the temperature difference between the indoor and outdoor air, the outdoor air 46a having a low temperature and heavy air The air flows into the room from below, and light air 46b having a high temperature in the room is discharged to the outside from above the window.

  As described above, the horizontal axis rotary window 16 combines the upper panel 1a with the rotary shaft 2 eccentric upward and the panel 1b with the downward eccentricity, so that only one side of the building can supply and exhaust air according to the wind direction. Both of the above can be performed, and cold air outside the room is taken into the living area in the lower part of the room through the lower panel 1b opened at the positive pressure, and can be exhausted outside through the upper panel 1a that opened the heat pool at the upper part of the room at the negative pressure. Efficient ventilation can be performed without disturbing indoor temperature stratification. Incidentally, contrary to the present embodiment, when the upper panel 1a is eccentric with the rotary shaft 2 downward and the lower panel 1b is eccentric with the rotary shaft 2 upward, the upper panel 1a is at positive pressure. Is opened and the lower panel 1b is closed, so that the outdoor temperature is low and heavy air flows in from the top of the window to disturb the temperature stratification in the room, and the negative pressure causes the upper panel 1a to close and the lower panel 1b to close. It cannot open and exhaust the heat pool in the upper part of the room, so efficient ventilation cannot be performed.

  Further, the horizontal axis rotation window portion 16 has a gap 8 between the rising portion 6 and the drooping portion 7 of the horizontal axis rotation panels 1a and 1b adjacent to each other in the vertical direction. Since the horizontal connecting material 5 is not visible from the indoor side and the outdoor side when the panel is closed, the design is improved. In addition, since the horizontal connecting member 5 is installed between the frame frames 4 and 4 between the horizontal axis rotary panels 1a and 1b adjacent to each other in the vertical direction, deformation such as twisting of the frame frame 4 can be reliably prevented. The shaft rotating window portion 16 can be effectively reinforced. The horizontal frame rotating panels 1a and 1b can be attached easily and with high accuracy because the horizontal frame 4 and 4 are parallel to each other without deformation such as torsion in the vertical frame 4. Furthermore, when the horizontal axis rotating panels 1a and 1b are open, a person falls off between the upper and lower horizontal axis rotating panels 1a and 1b, or a suspicious person enters between the upper and lower horizontal axis rotating panels 1a and 1b. It is possible to prevent the lateral connecting material 5 from trying.

  The horizontal axis rotary panels 1a and 1b are formed by combining the same members 23, 24, and 25 in the upper panel 1a and the lower panel 1b, and only the position of the rotary axis 2 and the mounting position of the weight 3 are set with the same outer shape. Since they are different, the cost can be kept low and design continuity can be obtained. Since the weight 3 is attached to the inside of the panel and the weight 3 cannot be seen from the outside, it is compared with a conventional natural ventilation window (see, for example, Japanese Patent No. 3128566) in which the weight 3 is protruded and attached to the indoor side of the panel. , Can improve the design.

  Further, the horizontal axis rotating window 16 is provided with a pressing protrusion 11 on the slide bar 9 that slides along the frame 4 toward the outdoor side, and the sliding bar 9 slides upward so that the pressing protrusion 11 is on the horizontal axis. The horizontal axis rotary panels 1a and 1b are closed by pushing the indoor side surface (flat part 38) above the rotary shaft 2 of the rotary panels 1a and 1b, the slide bar 9 slides downward, and the pressing protrusion 11 is horizontal axis. Since the horizontal axis rotary panels 1a and 1b are opened by climbing over the protrusions 10 of the rotary panels 1a and 1b, the opening / closing mechanism 36 can be simplified and installed in an inconspicuous state inside the room. Further, as in the present embodiment, even when a plurality of horizontal axis rotary panels 1a and 1b are provided continuously in the vertical direction, the pressing protrusion 11 on the slide bar 9 corresponding to the protrusion 10 of each horizontal axis rotary panel 1a and 1b. It is only necessary to provide a plurality of and can be easily implemented at low cost.

9 and 10 show another embodiment of the opening device of the present invention, which is an embodiment applied to a building sash. In this sash, a sash frame 47 to be attached to the housing opening is formed in a vertically long rectangle extending from the ceiling to the floor, and a fitting window portion 15 is provided in an intermediate portion in the vertical direction in the sash frame 47. Two horizontal axis rotary panels 1a and 1b are provided above and below continuously in the vertical direction. The upper two horizontal axis rotary panels 1a and 1a are provided with the rotary shaft 2 eccentrically above the middle in the vertical direction of the panel, and the weight 3 is mounted in the panel above the rotary shaft 2. The two horizontal axis rotary panels 1b and 1b on the lower side are provided at positions where the rotary shaft 2 is decentered downward from the middle in the vertical direction of the panel, and below the rotary shaft 2. The lower panel has a weight 3 attached in the panel.
Similarly to the embodiment described above, this sash also opens only the lower panel 1b at the time of positive pressure, and opens only the upper panel 1a at the time of negative pressure, and efficiently ventilates with a single window provided on one side of the building. Yes.

  The present invention is not limited to the embodiments described above. The upper panel and the lower panel may be ones in which a transparent panel such as glass is fitted in a square frame of four ridges. Also, the shape and size of the upper panel and the lower panel may be different. it can.
