Description

  The present invention relates to a horizontal axis rotary window, and more particularly to a horizontal axis rotary window and a building in which a shoji can be opened and closed naturally by wind pressure when the shoji receives wind.

A natural ventilation window is known in which a shoji screen receives a wind to open and close naturally to perform ventilation (see, for example, Patent Document 1).
This natural ventilation window is a kind of horizontal axis rotation window, and by placing a horizontal rotation axis above the central position in the vertical direction of the shoji, the shoji is supported in an eccentric state. In addition, a weight is attached above the shoji pivot position and on the indoor side of the shoji. With this weight, the lower end of the shoji opens to the outdoor side when there is no wind, so that it opens naturally. ing.
Furthermore, when wind is applied to the shoji from the outdoor side, the shoji has a larger area below the pivot support position, and therefore, the lower end side of the shoji moves in the indoor direction so that the shoji can be closed.
Therefore, when the wind pressure is relatively low, if the shoji can be opened naturally and ventilated, and if a strong wind blows from the outside of the room to the inside of the room, a positive pressure exceeding the specified value is applied to the shoji. The shoji can be closed automatically and the blowing of wind can be prevented.

JP 2005-146544 A

However, in the above-mentioned patent document 1, since the rotation shaft is eccentrically arranged above the central position in the vertical direction of the shoji, the shoji is closed only when wind blows from the outdoor side to the indoor side and positive pressure is applied to the shoji. I can't. For this reason, when negative pressure is applied to the shoji and wind blows from the indoor side to the outdoor side, the shoji cannot be closed.
In addition, it is conceivable to provide a weight on the outdoor side of the shoji so that the lower end of the shoji opens to the indoor side, but in this case, the shoji can be closed when negative pressure is applied to the shoji. Conversely, when a positive pressure is applied to the shoji, the shoji cannot be closed.
Therefore, the conventional natural ventilation window of the horizontal axis rotating window type has a problem that the function of automatically preventing the blowing of wind can be realized only for either positive pressure or negative pressure.

Moreover, in the conventional natural ventilation window of the horizontal axis rotation window type, it is necessary to provide the weight on the shoji, and there is a problem that the cost increases and durability and workability decrease due to an increase in the weight of the shoji.
An object of the present invention is a horizontal axis rotary window that can eliminate the weight, reduce the weight of the shoji, and can close the shoji even when the positive or negative pressure is applied to the shoji. And to provide buildings.

The horizontal axis rotation window of the present invention includes a window frame, a shoji, and a horizontal rotation shaft that rotatably supports the shoji with respect to the window frame, and the rotation shaft is in the height direction of the shoji. And is attached to the window frame so that the position of the window frame can be adjusted in the expected direction with respect to the vertical frame of the window frame and the vertical frame of the shoji. It is arranged at a position separated by a predetermined distance.

According to the present invention, since the rotation axis of the shoji is set at the center position in the height direction of the shoji, the rotation axis of the shoji is set at the same height as the center of gravity of the shoji. Moreover, since the said rotating shaft is arrange | positioned in the position which left | separated predetermined distance in the prospective direction with respect to the gravity center position of a shoji, the distance between a rotating shaft and a gravity center can be set to predetermined length. Therefore, since the center of gravity and the rotation axis of the shoji are shifted in the expected direction, a rotational moment in the direction of opening the shoji is generated without providing a weight. At this time, by setting the length between the rotation axis and the center of gravity, the magnitude of the rotation moment can also be set in advance. Therefore, if there is no wind or a wind speed of about a slight wind to a weak wind, the shoji can be automatically opened by the rotational moment, and natural ventilation can be realized.
Furthermore, since the shoji has the rotation axis set at the center position in the height direction of the shoji, the area above the rotation axis and the lower area of the shoji can be set to substantially the same area. For this reason, in both cases where winds of medium or strong wind speed are blowing from the outdoor side to the indoor side (in the case of positive pressure) and when blowing from the indoor side to the outdoor side (in the case of negative pressure) When the wind hits, the shoji can be rotated in the closing direction with a force larger than the rotational moment, and can be automatically closed.
For this reason, strong wind can be automatically prevented from blowing in or blowing out from the horizontal axis rotation window. Therefore, a favorable natural ventilation state can be maintained by arranging the horizontal axis rotation window of this embodiment according to the natural ventilation plan of a building.
In addition, since it is not necessary to provide a weight for the shoji, the shoji can be reduced in weight, the durability and workability of the horizontal axis rotary window can be improved, and the cost can be reduced.

According to the present invention, since the position of the rotation shaft can be adjusted in the expected direction of the window frame, the magnitude of the rotation moment can be adjusted by adjusting the center of gravity of the shoji and the length between the rotation shafts. For this reason, since the wind pressure which closes a shoji automatically can be adjusted according to the installation place of a horizontal axis rotation window, a user's request, etc., it can be set as a convenient horizontal axis rotation window.

  In the horizontal axis rotating window of the present invention, the shaft member is attached to one of the vertical frame and the vertical rod so as to be position-adjustable in the prospective direction and provided with the rotary shaft, and the vertical frame and the vertical rod. It is preferable to include a bearing member that is attached to the other side in such a manner that its position can be adjusted in the prospective direction and that has a shaft hole through which the rotating shaft is rotatably inserted.

  According to the present invention, since the shaft member and the bearing member are attached to the window frame and the shoji so that the position of the shaft member and the shoji can be adjusted in the expected direction, only the rotation shaft of the shoji is used without changing the relative position of the window frame and the shoji. It can be easily adjusted in the expected direction (indoor / outdoor direction). Therefore, even when the position of the center of gravity of the shoji changes due to a change in the weight of the glass or the attachment position, the rotation axis can be arranged at an appropriate position according to the position of the center of gravity. For this reason, according to the environment of a building, etc., the function of a horizontal axis rotation window can also be finely adjusted, and the natural ventilation state suitable for a building can be maintained favorably.

  In the horizontal axis rotation window of the present invention, the door frame is a door contact member that abuts against the shoji and regulates a rotation angle when the shoji rotates from a state of closing the opening of the window frame to a state of opening. When the wind speed of the wind hitting the shoji is less than a threshold, the predetermined distance is determined by the rotational moment generated in the shoji due to the rotation axis and the center of gravity being separated from each other by a predetermined distance in the expected direction. It is preferable that the shoji is set to rotate in the closing direction when the shoji rotates to a position where it comes into contact with the door stop member and the wind speed of the wind hitting the shoji is equal to or higher than a threshold value.

  According to the present invention, since the rotation angle of the open state of the shoji can be regulated by the door contact member, the fully open state of the shoji can be made constant and stable. For this reason, the setting of the distance between a rotating shaft and a gravity center can be performed easily. That is, the distance between the rotation axis and the center of gravity may be set to be equal to or greater than the distance that rotates at least to the angle that contacts the door-contact member when the shoji is opened. Therefore, the specific distance can be easily adjusted according to the setting of the wind speed for rotating the shoji in the closing direction.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In addition, in each figure, in order to make a drawing legible, about the main structural member, the hatching of the cross-sectional part may be abbreviate | omitted.

[First Embodiment]
As shown in FIGS. 1-3, 1st Embodiment is the continuous window 1 comprised by arrange | positioning the two horizontal axis | shaft rotation windows 2 on either side.
The continuous window 1 is an intermediate position of the left and right vertical frames 3 and 4, the upper frame 5 and the lower frame 6 that connect the upper and lower ends of the vertical frames 3 and 4, and the direction in which the continuous window 1 is found (left and right direction). And a stand 7 disposed between the upper frame 5 and the lower frame 6.
Accordingly, the left vertical frame 3, the upper frame 5 and the lower frame 6, and the vertical (vertical frame) 7 as viewed from the indoor side constitute the window frame 10 of the left horizontal axis rotation window 2. Further, the right vertical frame 4, the upper frame 5 and the lower frame 6, and the vertical (vertical frame) 7 as viewed from the indoor side constitute a window frame 10 of the right horizontal axis rotation window 2.
[Window frame]
In each window frame 10, the shojis 20, 20 of the horizontal axis rotation window 2 are rotatably supported via a hinge device 30 described later.
Each shoji 20 is a shoji having the same structure, and is constructed by framing left and right vertical gutters 21 and 22, an upper gutter 23, and a lower gutter 24, and incorporating a multi-layer glass 25 therein.
The shoji 20 of the present embodiment is configured such that when opened, the lower end side moves to the outdoor side and the upper end side moves to the indoor side.

[Door-to-door members]
As shown in FIGS. 1 and 3, the left and right vertical frames 3, 4 of the continuous window 1 are attached with door stop members 8 against which the shojis 20 come into contact when the shojis 20, 20 are opened. For this reason, when the shoji 20 is rotated in the opening direction, the shoji 20 is rotated only to a position where it is in contact with the door stop member 8.

[Hinge device]
The hinge devices 30 are arranged on the left and right sides of the shoji 20, respectively. That is, as shown in FIG. 2, between the vertical frame 3 and the vertical wall 21, between the vertical wall 22 and the vertical wall 7, between the vertical wall 7 and the vertical wall 21, the vertical wall 22 and the vertical frame 4, Are arranged respectively. Since the structure of each hinge apparatus 30 is the same, the hinge apparatus 30 arrange | positioned between the vertical frame 3 and the vertical rod 21 is demonstrated based on FIGS.
FIG. 4 is a plan sectional view of the hinge device 30 along the line BB in FIGS. FIG. 5 is a side view of the shaft member 31, and FIG. 6 is a side view of the bearing member 35. FIG. 7 is a plan sectional view of the hinge device 30 taken along the line CC in FIGS.
The hinge device 30 includes a shaft member 31 provided with a rotation shaft 320 and a bearing member 35 into which the rotation shaft 320 is rotatably inserted.
The shaft member 31 is attached to one of the window frame 10 or the shoji 20, and the bearing member 35 is attached to the other. 4 to 7, the shaft member 31 is attached to the vertical rod 21 of the shoji 20, and the bearing member 35 is attached to the vertical frame 3 of the window frame 10.

[Configuration of shaft member]
As shown in FIGS. 4 and 5, the shaft member 31 includes a plate 310 and a round bar-shaped rotating shaft 320 screwed to the plate 310.
The plate 310 is formed in a substantially rectangular side surface, and long holes 312 and 312 are formed at positions above and below the rotation shaft 320. These elongated holes 312 and 312 are elongated holes extending along the prospective direction (indoor / outdoor direction) of the horizontal axis rotary window 2.
The shaft member 31 is fixed to the vertical rod 21 by inserting a screw 313 into each elongated hole 312 and screwing it into the vertical rod 21.

[Position adjustment of shaft member in the expected direction]
Further, on the surface of the plate 310 facing the vertical rod 21, an uneven strip (giza) 315 is formed along the vertical direction (height direction) of the vertical rod 21. The uneven strip 315 is formed in a sawtooth cross section.
The vertical base 21 is screwed with a hinge base 33 on which concave / convex ridges 335 that mesh with the concave / convex 315 are formed.
By changing the meshing position of the ridges 315 of the shaft member 31 and the ridges 335 of the hinge base 33, the position of the shaft member 31 in the expected direction (indoor / outdoor direction) with respect to the hinge base 33, that is, the vertical rod 21 Can be changed. For example, when the uneven strips 315 and 335 are processed at a pitch of 1 mm, the position of the shaft member 31 in the indoor / outdoor direction can be changed by 1 mm.
Specifically, the screw 313 is loosened to release the engagement of the uneven strips 315 and 335, the shaft member 31 is moved to a predetermined position in the prospective direction, the screw 313 is tightened, and the uneven strips 315 and 335 are engaged again. Thus, the position of the shaft member 31 in the prospective direction is adjusted.

[Configuration of bearing member]
As shown in FIGS. 4 and 6, the bearing member 35 includes a bearing plate 350 and a lid member 360 that is screwed to the bearing plate 350.
The bearing plate 350 has a substantially rectangular side surface, and a bearing groove 351 that opens toward the indoor side is formed at an intermediate position in the vertical direction. Long holes 352 and 352 are formed at positions above and below the groove 351. These elongated holes 352 and 352 are elongated holes extending along the prospective direction (indoor / outdoor direction) of the horizontal axis rotary window 2.
The bearing member 35 is fixed to the vertical frame 3 by inserting a screw 353 into each of the long holes 352 and screwing it into the vertical frame 3.

  The lid member 360 is screwed to the opening side of the groove 351, that is, the indoor side surface of the bearing plate 350. Accordingly, the opening of the groove 351 is closed by the lid member 360, and a shaft hole that rotatably supports the rotating shaft 320 is formed.

[Position adjustment of bearing member in the expected direction]
On the surface of the bearing plate 350 that faces the vertical frame 3, an uneven strip (gear) 355 is formed along the vertical direction (height direction) of the vertical frame 3. The uneven strip 355 is formed in a sawtooth cross section.
The vertical frame 3 is screwed with a hinge base 38 on which concave and convex strips (giza) 385 that mesh with the concave and convex strips 355 are formed.
The position of the bearing member 35 in the expected direction (indoor / outdoor direction) with respect to the hinge base 38, that is, the vertical frame 3, by changing the meshing position of the concave / convex strip 355 of the bearing member 35 and the concave / convex strip 385 of the hinge base 38. Can be changed. Here, since the pitch of the concavo-convex strips 355 and 385 is the same as that of the concavo-convex strips 315 and 335, the bearing member 35 can change the position in the prospective direction by the same dimension as the shaft member 31.
Specifically, the screw 353 is loosened to release the engagement with the concave and convex strips 355 and 385, the bearing member 35 is moved to a predetermined position in the prospective direction, the screw 353 is tightened, and the concave and convex strips 355 and 385 are again tightened. The position of the bearing member 35 in the expected direction is adjusted.

As described above, the shaft member 31 and the bearing member 35 of the hinge device 30 can be attached to the window frame 10 and the shoji 20 so as to be positionally adjustable. For this reason, the position of the rotating shaft 320 of the shoji 20 can be adjusted in the expected direction without changing the relative positions of the window frame 10 and the shoji 20.
Specifically, the shaft member 31 and the bearing member 35 can move within the range of the dimensions of the elongated holes 312, 352, and within this range, for each pitch dimension of the ridges 315, 335, 355, and 385, The position of the rotary shaft 320 of the shoji 20, that is, the position of the axis 321 that is the central axis of the rotary shaft 320 can be adjusted.
For example, FIGS. 4 to 7 show a state in which the rotary shaft 320 of the shoji 20 is provided most indoors within the range of the long holes 312 and 352. 8 and 9 show a state in which the rotary shaft 320 of the shoji 20 is provided on the most outdoor side within the range of the long holes 312 and 352. Here, the dimension from the outdoor surface of the vertical shaft 21 to the axis 321 is the dimension L1 in the case of FIG. 4, the dimension L2 in the case of FIG. 8, and the relationship L1> L2.

[Center of gravity of shoji]
The position in the height direction of the center of gravity 201 of the shoji 20 is set to the center position in the height direction of the shoji 20. In other words, the shoji 20 is not provided with a weight as in the prior art document. Therefore, most of the weight of the shoji 20 is the weight of the multilayer glass 25. For this reason, the center position of the multilayer glass 25 in the height direction matches the position of the center of gravity 201 of the shoji 20 in the height direction.
In addition, since the squeezing dimension of the glass in the upper ridge 23 and the lower ridge 24 holding the multilayer glass 25 is normally set to the same dimension, the center position in the height direction of the multilayer glass 25 is the glass of the shoji 20. It coincides with the center position of the opening in the height direction. The center position in the height direction of the glass opening of the shoji 20 is the center position of the height dimension from the lower end surface of the upper eyelid 23 holding the multilayer glass 25 to the upper end surface of the lower eyelid 24. That is, it is the center position of the height dimension of the apparent portion of the multilayer glass 25.
Further, the position in the prospective direction of the center of gravity 201 of the shoji 20 is disposed between the double glazing 25.

[Relationship between the axis of the rotating shaft of the shoji and the center of gravity]
In this embodiment, as shown in FIG. 10, the axis 321 of the rotation shaft 320 of the shoji 20 is at the same height as the center of gravity 201 of the shoji 20 and the position in the prospective direction with respect to the center of gravity 201 is displayed. The position is set to be shifted outward. That is, by adjusting the position of the shaft member 31 of the hinge device 30 and the bearing member 35 in the prospective direction with respect to the window frame 10 and the shoji 20, the position of the prospective direction of the shaft center 321 (rotary shaft 320) with respect to the center of gravity 201 It has been adjusted.
In addition, when the gravity center 201 is located on the indoor side with respect to the axis 321 of the rotation shaft 320, the shoji 20 generates a rotation moment N in a direction in which the upper end side moves to the indoor side. The rotational moment increases as the distance between the axis 321 of the rotary shaft 320 and the center of gravity 201 increases. Therefore, in this embodiment, the shaft center 321 (rotating shaft 320) is set at a position that satisfies the following conditions. That is, the predetermined distance between the axis 321 and the center of gravity 201 is set based on the following conditions.

[Conditions for axial position of the rotary shaft of the shoji]
(1) Fully open state when there is no wind When the wind pressure is not applied to the shoji 20 of the horizontal axis rotary window 2 when there is no wind, the center of gravity 201 is eccentric to the indoor side with respect to the axis 321 of the rotary shaft 320. As a result, a rotational moment N is generated in the shoji 20, and the upper end moves to the indoor side. The positional relationship (predetermined distance) between the center of gravity 201 and the shaft center 321 is set so that the shoji 20 is rotated at least to a position where it is in contact with the door contact member 8 by this rotational moment N. In the present embodiment, the shoji 20 is set to rotate 45 degrees from the closed position to the position where the shoji 20 contacts the door stop member 8.
Therefore, the shoji 20 of the horizontal axis rotation window 2 automatically rotates to the position shown in FIG. 11 when there is no wind, and opens the horizontal axis rotation window 2. For this reason, the horizontal axis rotation window 2 can be in a natural ventilation state.

(2) Maintain the fully open state when the wind speed is less than the threshold value.
When a light wind to a weak wind is blown, that is, when the wind pressure applied to the shoji 20 is less than the set threshold, a force for rotating the shoji 20 in the closing direction is applied. In this case, the rotation moment N for rotating the shoji 20 in the opening direction due to the eccentricity of the shaft center 321 and the center of gravity 201 is larger than the rotation moment for rotating the shoji 20 in the closing direction by wind pressure. The distance between the center 321 and the center of gravity 201 is set to a predetermined distance.

(3) When the wind speed is higher than the threshold value, the shoji should be rotated in the closing direction.
When a wind of medium to strong wind blows and the wind pressure applied to the shoji 20 exceeds a set threshold value, the rotational moment that rotates the shoji 20 in the closing direction by the wind pressure causes the shaft center 321 and the center of gravity 201 to be expected. The distance between the shaft center 321 and the center of gravity 201 is set to a predetermined distance so as to be larger than the rotational moment N that rotates the shoji 20 in the opening direction due to the eccentricity of the direction.
(3-1) In the case of positive pressure For example, as shown in FIG. 12, when the wind W1 blows toward the wall surface to which the horizontal axis rotary window 2 (continuous window 1) is attached in the building, that is, the horizontal axis rotates. When the wind W1 blows from the outdoor side of the window 2 toward the indoor side, positive pressure from the outdoor side toward the indoor side is applied to a portion below the rotary shaft 320 of the shoji 20 located on the windward side. For this reason, the lower half of the shoji 20 is pushed toward the indoor side and rotates in the closing direction. Since the positive pressure applied to the shoji 20 increases as the wind speed increases, the opening angle of the shoji 20 decreases as the wind speed increases. And when the wind more than the predetermined 2nd threshold value larger than the said threshold value blows, the shoji 20 will be closed completely.
(3-2) In the case of negative pressure Similarly, as shown in FIG. 13, when the wall surface to which the horizontal axis rotary window 2 (continuous window 1) is attached is leeward in the building, the horizontal axis rotary window 2 includes Wind W2 from the indoor side toward the outdoor side blows and negative pressure is applied. In this case, a negative pressure from the indoor side toward the outdoor side is applied to the upper half of the rotary shaft 320 of the shoji 20 located on the windward side. For this reason, the upper half of the shoji 20 is pushed toward the outdoor side and rotates in the closing direction. Since the negative pressure applied to the shoji 20 also increases as the wind speed increases, the opening angle of the shoji 20 decreases as the wind speed increases. And when the wind more than the predetermined 2nd threshold value larger than the said threshold value blows, the shoji 20 will be closed completely.

[Relationship between wind speed and shoji angle]
Here, FIG. 14 shows the results of experiments on the relationship between the wind speed and the angle of the shoji 20 using the two horizontal axis rotation windows 2 having different distances between the axis 321 and the center of gravity 201.
In FIG. 14, the broken line 101 is an experimental result of the first horizontal axis rotation window 2 in which the axis 321 is set on the indoor side and the distance between the axis 321 and the center of gravity 201 is shortened. On the other hand, the broken line 102 has a shaft 321 that is set on the outdoor side, and the distance between the shaft 321 and the center of gravity 201 is longer than that of the first horizontal shaft 2. It is an experimental result.
For this reason, the first horizontal axis rotary window 2 has a smaller rotational moment due to the center of gravity 201 than the second horizontal axis rotary window 2.
Accordingly, the folding line 101 moves in the closing direction at a lower wind speed than the broken line 102, and the opening angle of the folding line 20 is also reduced. The wind speed at which the shoji 20 is fully closed is also smaller than that of the broken line 102.
On the other hand, the folding line 102 does not move in the closing direction unless the wind speed is higher than that of the broken line 101. As the wind speed increases, the opening angle of the shoji 20 also decreases. The wind speed at which the shoji 20 is fully closed is also larger than that of the broken line 101, and the shoji 20 is not fully closed unless the wind speed is higher.

According to the present embodiment, the following effects are obtained. (1) In the horizontal axis rotation window 2, the hinge device 30 can be adjusted with respect to the window frame 10 and the shoji 20 in the expected direction, and the window Without changing the relative positions of the frame 10 and the shoji 20, only the axial center 321 of the shoji 20 can be adjusted in the prospective direction (indoor / outdoor direction).
Further, the axial center 321 of the shoji 20 is set at the center position of the shoji 20 in the height direction. For this reason, the axis 321 of the rotating shaft 320 of the shoji 20 is set to the same height position as the center of gravity 201 of the shoji 20, and the distance between the axis 321 and the center of gravity 201 can be adjusted by the movement of the hinge device 30. Accordingly, the shoji 20 has a center of gravity 201 and an axial center 321 that are eccentric in the expected direction, so that a rotational moment in a direction to open the shoji 20 is generated, and if the wind speed is less than a threshold of about a slight wind to a weak wind, The shoji 20 can be automatically opened to the angle at which the shoji 20 contacts the door stop member 8, and natural ventilation can be realized.
Furthermore, since the shoji 20 sets the axial center 321 at the center position in the height direction of the shoji 20, the area above the axial center 321 and the lower area of the shoji 20 are set to substantially the same area. it can. For this reason, when winds with wind speeds above the threshold, such as medium to strong winds, are blowing from the outdoor side to the indoor side (positive pressure) and from the indoor side to the outdoor side (in the case of negative pressure) In either case, the shoji 20 can be set to automatically close, and strong wind can be automatically prevented from blowing in or blowing out from the horizontal axis rotation window 2.
Therefore, a favorable natural ventilation state can be maintained by arranging the horizontal axis rotation window 2 of the present embodiment according to the natural ventilation plan of the building.

(2) When the wind speed increases, the opening angle of the shoji 20 is automatically reduced, and when the wind speed is equal to or higher than the second threshold, the shoji 20 can be automatically fully closed. For this reason, excessive ventilation can be suppressed and an indoor airflow state can be kept favorable.
Furthermore, it is not necessary to provide a special ventilation device for excessive ventilation suppression, and the cost of the horizontal axis rotary window 2 can be reduced.

(3) Since it is not necessary to provide a weight on the shoji 20, the aesthetic appearance of the horizontal axis rotary window 2 can be improved. Furthermore, since the shoji 20 can be reduced in weight, the durability and workability of the horizontal axis rotary window 2 can be improved, and the cost can be reduced.

(4) Since the position of the expected direction of the hinge device 30 can be adjusted with respect to the window frame 10 and the shoji 20, the wind speed at which the shoji 20 begins to close (threshold) and the wind speed at which the shoji 20 is fully closed (second threshold) You can adjust the settings. Accordingly, the function can be selected with one type of horizontal axis rotary window 2, and the setting can be switched even after the horizontal axis rotary window 2 is constructed in the building. For this reason, according to the environment of the constructed building, etc., the function of the horizontal axis rotary window 2 can be finely adjusted after the construction, and the natural ventilation state suitable for the building can be maintained well.

(5) The hinge device 30 is formed with concave and convex strips 315 and 355 on the shaft member 31 and the bearing member 35, respectively, and the hinge bases 33 and 38 attached to the vertical frames 3 and 4, the vertical 7 and the vertical rods 21 and 22, respectively. The position is adjusted by engaging the ridges 335 and 385. For this reason, the position of the shaft member 31 and the bearing member 35 can be accurately adjusted with a simple structure and every fixed pitch. For this reason, even when the thickness dimension of the glass incorporated in the shoji 20 is different, or when the position of the center of gravity 201 is changed in the shoji 20 as in the case where a single plate glass is incorporated, the hinge device according to the position of the center of gravity 201. The position of 30 prospective directions can be easily adjusted, and the magnitude of the rotational moment can be appropriately set to a desired value.

[Second Embodiment]
Next, 2nd Embodiment of this invention is described based on drawing. In addition, about the structure same as 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted suitably. 15 is a view of the continuous window 1B using the horizontal axis rotary window 2B according to the second embodiment of the present invention as viewed from the indoor side, and FIG. 16 is a plan sectional view taken along the line DD of FIG. It is.
The horizontal axis rotary window 2B is different from the horizontal axis rotary window 2 of the first embodiment in that a regulating device 40 that regulates the closing of the shoji 20 is added. Since other configurations are the same as those of the first embodiment, description thereof is omitted.

The restricting device 40 includes a stopper receiving member 41 fixed to the vertical frame 7 of the window frame 10 and a stopper member 45 attached to the shoji 20.
As shown in FIGS. 16 to 18, the stopper receiving member 41 has a substantially L-shape including a fixing portion 411 fixed to the prospective surface of the stand 7 and a receiving portion 412 extending from the fixing portion 411 in the direction of finding. It is composed of a bracket.

  The stopper member 45 includes a substantially L-shaped support bracket 46 fixed to the vertical rods 21 and 22, and a horizontal shaft member that is supported on one end side by the support bracket 46 and arranged along the direction in which the horizontal axis rotary window 2 </ b> B is found. 47, an auxiliary wing stopper 48 rotatably attached to the horizontal shaft member 47, and a retaining ring 49 such as an E ring for preventing the auxiliary wing stopper 48 from coming off.

  The auxiliary wing stopper 48 includes a stopper main body 481 and an auxiliary wing 482 as a wind receiving portion. As shown in FIG. 18, the stopper main body 481 includes support portions 485 and 486 that are pivotally supported by the horizontal shaft member 47, an arc-shaped curved portion 487 that connects the support portions 485 and 486, and one support. And a contact portion 488 extended from the portion 486 toward the indoor side.

  The auxiliary wing 482 is made of a thin plate material, is bent along the inner peripheral surface of the bending portion 487, and is attached to the bending portion 487. The auxiliary wing 482 extends downward from the stopper body 481. For this reason, the auxiliary wing stopper 48 is in a posture in which the auxiliary wing 482 is vertically aligned due to the weight of the auxiliary wing 482 when there is no wind. On the other hand, when the wind hits the auxiliary wing 482, the auxiliary wing stopper 48 rotates with respect to the horizontal shaft member 47.

[Auxiliary wing stopper 48 position]
(Shoji closed position: When the rotation angle is 0 degree)
The state of the auxiliary wing stopper 48 when the shoji 20 is in the closed position is shown by a two-dot chain line in FIG. In this case, the auxiliary blade stopper 48 is provided at a position where the contact portion 488 is located above the receiving portion 412 of the stopper receiving member 41.
(Shoji opening position: When the rotation angle is 45 degrees)
The state of the auxiliary blade stopper 48 when the shoji 20 is in the open position and no wind is shown by a solid line in FIG. In this case, the contact portion 488 of the auxiliary blade stopper 48 is provided such that the position in the height direction is above the receiving portion 412 and the position in the prospective direction is located on the outdoor side of the receiving portion 412. .
The stopper member 45 is attached to a predetermined position with respect to the shaft center 321 of the shaft member 31 so as to satisfy the above conditions.

[Closing action at positive pressure]
When the shoji 20 of the horizontal axis rotation window 2B is in a fully open state (shoji angle 45 degrees), when wind blows from the outdoor side to the indoor side, as shown in FIG. 19, the auxiliary blade 482 of the stopper member 45 is applied to the auxiliary wing 482. The wind (positive pressure) from the outdoor side to the indoor side is also hit. Therefore, as shown in FIG. 19, the stopper member 45 rotates in the direction in which the auxiliary wing 482 moves to the indoor side with the horizontal shaft member 47 as the center of rotation. For this reason, the stopper member 45 moves to a position indicated by a two-dot chain line, and the contact portion 488 moves in a direction away from the receiving portion 412. For this reason, the contact part 488 of the stopper member 45 does not contact the receiving part 412, and the shoji 20 rotates in the closing direction by the positive pressure as in the first embodiment.

[Closed operation under negative pressure]
When the shoji 20 of the horizontal axis rotary window 2B is in a fully open state (shoji angle of 45 degrees), when wind blows from the indoor side to the outdoor side, as shown in FIG. 20, the auxiliary wing 482 of the stopper member 45 is applied to the auxiliary wing 482. The wind (negative pressure) from the indoor side to the outdoor side is also hit. Therefore, as shown in FIG. 20, the stopper member 45 rotates in the direction in which the auxiliary wing 482 moves to the outdoor side with the horizontal shaft member 47 as the center of rotation. For this reason, the stopper member 45 moves to a position indicated by a two-dot chain line, and the abutting portion 488 moves to a height position where it abuts on the receiving portion 412. For this reason, when the shoji 20 rotates in the closing direction due to negative pressure, the abutting portion 488 comes into contact with the receiving portion 412, and the shoji 20 can no longer rotate in the closing direction.

Accordingly, when the horizontal axis rotation window 2B of the second embodiment is windless or light to light, the shoji 20 automatically moves to an open state and enters a natural ventilation state as in the first embodiment.
In addition, when a medium wind to a strong wind (positive pressure) is applied to the shoji 20 from the outdoor side to the indoor side, the shoji 20 automatically rotates in the closing direction as in the first embodiment. Prevent the blowing of wind.
On the other hand, when a medium to strong wind (negative pressure) is applied to the shoji 20 from the indoor side to the outdoor side, unlike the first embodiment, the stopper member 45 of the regulating device 40 is attached to the stopper receiving member 41. By the contact, the shoji 20 cannot be rotated in the closing direction. For this reason, the shoji 20 remains open, and ventilation (exhaust) is performed by the wind from the indoor to the outdoor.

[Effects of Second Embodiment]
According to the horizontal axis rotation window 2B of the second embodiment as described above, the same operational effects can be achieved by providing the same configuration as the horizontal axis rotation window 2 of the first embodiment.
In addition, since the regulating device 40 is provided, when the wind blows from the outdoor side to the indoor side (in the case of positive pressure), the shoji 20 can be rotated in the closing direction, while the wind blows from the indoor side to the outdoor side. In this case (in the case of negative pressure), rotation of the shoji 20 in the closing direction can be restricted. Therefore, it is possible to provide the horizontal axis rotary window 2B suitable for the case where the shoji 20 needs to be kept open at the time of negative pressure in order to perform ventilation (exhaust) from indoor to outdoor in a building.

Furthermore, the stopper receiving member 41 and the stopper member 45 of the regulating device 40 have a simple structure, and are in a closed permission state (at the time of positive pressure) only by a difference in operation of the stopper member 45 at the time of positive pressure and negative pressure. Open maintenance state (at negative pressure) can be selected. Therefore, since the regulating device 40 does not require an electric mechanism or the like, it can be configured at a low cost, and can operate reliably even during a power failure because it operates only with wind pressure.
In addition, since the auxiliary wing 482 has a flat cross-sectional shape curved outward, the stopper member 45 can be reliably rotated even with a weak wind pressure, particularly at negative pressure. For this reason, at the time of negative pressure, the movement to the closing direction of the shoji 20 can be controlled reliably.

[Third Embodiment]
Next, a horizontal axis rotation window 2C according to a third embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the restricting device 40 for maintaining the shoji 20 in the open state at the time of negative pressure is provided. In the third embodiment, the restricting device 50 for maintaining the shoji 20 in the open state at the time of positive pressure is provided. It is. Therefore, about the same structure as 2nd Embodiment, while attaching | subjecting the same code | symbol and abbreviate | omitting description suitably, only the control apparatus 50 is demonstrated.

The restriction device 50 includes a stopper receiving member 51 fixed to the vertical frame 7 of the window frame 10 and a stopper member 55 attached to the shoji 20.
The stopper receiving member 51 is configured by a substantially L-shaped bracket having a fixing portion 511 fixed to the prospective surface of the vertical 7 and a receiving portion 512 extended from the fixing portion 511 in the direction of finding.

  The stopper member 55 includes a substantially L-shaped support bracket 56 fixed to the vertical rods 21 and 22, and one end side supported by the support bracket 56, and a horizontal shaft member disposed along the direction in which the horizontal axis rotation window 2 </ b> C is located. 57, an auxiliary wing stopper 58 rotatably attached to the horizontal shaft member 57, and a retaining ring such as an E-ring (not shown) for preventing the auxiliary wing stopper 58 from coming off.

  The auxiliary wing stopper 58 includes a stopper main body 581 and an auxiliary wing 582 that is a wind receiving portion. As shown in FIG. 21, the stopper main body 581 includes two support portions 585 and 586 that are pivotally supported by the horizontal shaft member 57, an arc-shaped curved portion 587 that connects the two support portions 585, and one of the support portions 585 and 586. The contact portion 588 extends from the support portion 586 toward the outdoor side and has a locking groove formed on the lower surface thereof.

  Here, the support portions 585 and 586 of the auxiliary wing stopper 58, the curved portion 587, and the auxiliary wing 582 have the same configurations as the support portions 485 and 486, the curved portion 487, and the auxiliary wing 482 of the auxiliary wing stopper 48 of the second embodiment. It is. Therefore, the auxiliary wing stopper 58 is in a posture in which the auxiliary wing 582 is vertically aligned due to the weight of the auxiliary wing 582 when there is no wind. On the other hand, when the wind hits the auxiliary wing 582, the auxiliary wing stopper 58 rotates with respect to the horizontal shaft member 57.

[Auxiliary wing stopper 58 position]
(Shoji closed position: When the rotation angle is 0 degree)
Although the illustration of the auxiliary wing stopper 58 when the shoji 20 is in the closed position is omitted, the contact portion 588 is provided at a position above the receiving portion 512 of the stopper receiving member 51.
(Shoji opening position: When the rotation angle is 45 degrees)
The state of the auxiliary wing stopper 58 when the shoji 20 is in the open position and no wind is shown by solid lines in FIGS. In this case, the contact portion 588 of the auxiliary wing stopper 58 is provided at a position in the height direction above the receiving portion 512 and at a position where the receiving portion 512 is not locked in the groove of the contact portion 588.
The stopper member 55 is attached to a predetermined position with respect to the shaft center 321 of the shaft member 31 so as to satisfy the above conditions.

[Closing action at positive pressure]
When the shoji 20 of the horizontal axis rotary window 2C is in a fully open state (shoji angle 45 degrees), when wind blows from the outdoor side toward the indoor side, as shown in FIG. 21, the auxiliary wing 582 of the stopper member 55 is applied to the auxiliary wing 582. The wind (positive pressure) from the outdoor side to the indoor side is also hit. For this reason, as shown in FIG. 21, the stopper member 55 rotates in the direction in which the auxiliary wing 582 moves to the indoor side with the horizontal shaft member 57 as the rotation center. For this reason, the stopper member 55 moves to a position indicated by a two-dot chain line, and the contact portion 588 moves to the lower side, that is, the receiving portion 512 side. Therefore, the receiving portion 512 is disposed in the groove of the contact portion 588 of the stopper member 55. For this reason, when the shoji 20 is rotated in the closing direction by the positive pressure, the contact portion 588 comes into contact with the receiving portion 512, and the shoji 20 cannot be rotated further in the closing direction.

[Closed operation under negative pressure]
When wind is blown from the indoor side to the outdoor side when the shoji 20 of the horizontal axis rotary window 2C is fully open (shoji angle 45 degrees), as shown in FIG. 22, the auxiliary wing 582 of the stopper member 55 The wind (negative pressure) from the indoor side to the outdoor side is also hit. For this reason, as shown in FIG. 22, the stopper member 55 rotates in the direction in which the auxiliary wing 582 moves to the outdoor side with the horizontal shaft member 57 as the rotation center. For this reason, the stopper member 55 moves to a position indicated by a two-dot chain line, and the contact portion 588 moves in a direction away from the receiving portion 412 (upper side). For this reason, even if the shoji 20 rotates in the closing direction due to negative pressure, the contact portion 588 does not come into contact with the receiving portion 512, and the shoji 20 rotates in the closing direction due to the negative pressure as in the first embodiment. To do.

Therefore, the horizontal axis rotating window 2C according to the third embodiment, when there is no wind or a slight wind to a weak wind, as in the first and second embodiments, the shoji 20 automatically moves to the open state, Become.
In addition, when a medium wind to a strong wind (negative pressure) is applied to the shoji 20 from the indoor side to the outdoor side, the shoji 20 automatically rotates in the closing direction and goes indoors as in the first embodiment. Prevent the blowing of wind.
On the other hand, when medium wind to strong wind (positive pressure) is applied to the shoji 20 from the outdoor side to the indoor side, unlike the first and second embodiments, the stopper member 55 of the regulating device 50 is the stopper receiving member. By contacting 51, the shoji 20 cannot be rotated in the closing direction. For this reason, the shoji 20 remains open, and ventilation (intake) is performed by the wind from the outside to the indoor.

[Effect of the third embodiment]
According to the horizontal axis rotation window 2C of the third embodiment as described above, the same operational effects can be achieved by providing the same configuration as the horizontal axis rotation windows 2 and 2B.
Since the regulating device 50 is provided, when the wind blows from the indoor side to the outdoor side (in the case of negative pressure), the shoji 20 can be rotated in the closing direction, while the wind blows from the outdoor side to the indoor side. In this case (in the case of positive pressure), the rotation of the shoji 20 in the closing direction can be restricted. Therefore, in the building, in order to ventilate (intake air) indoors from the outside, it is possible to provide the horizontal axis rotary window 2C suitable for the case where the shoji 20 needs to be kept open at the time of positive pressure.

Further, the stopper receiving member 51 and the stopper member 55 of the restricting device 50 have the same structure as the restricting device 40, and are in a closed permission state only by the difference in operation of the stopper member 45 at the time of positive pressure and negative pressure ( It is possible to select between a negative pressure) and an open maintenance state (positive pressure). Therefore, since the regulating device 50 does not require an electric mechanism or the like, it can be configured at a low cost and can be reliably operated.
In addition, since the auxiliary wing 582 has a flat cross-sectional shape curved inward, the stopper member 45 can be reliably rotated even with a weak wind pressure, particularly during positive pressure. For this reason, at the time of a positive pressure, the movement to the closing direction of the shoji 20 can be controlled reliably.

[Fourth Embodiment]
Next, a horizontal axis rotation window 2D according to a fourth embodiment of the present invention will be described with reference to FIGS. The horizontal axis rotation window 2D of the fourth embodiment is similar to the horizontal axis rotation window 2B of the second embodiment in that the rotation of the shoji 20 is restricted at negative pressure, but the wind speed at the negative pressure is equal to or higher than a set value. Then, it differs in that it has a restricting device 40 for releasing the rotation restriction. Therefore, the same components as those of the second embodiment are denoted by the same reference numerals and description thereof is omitted as appropriate.

  The restriction device 60 of the fourth embodiment includes a stopper member 45 attached to the shoji 20, a fixed plate 62 fixed to the prospective surface of the vertical frame 3, and a stopper attached to the fixed plate 62 so as to be rotatable. A receiving member 61, an urging means 63 for urging the stopper receiving member 61 to the outdoor side, and an adjusting means 65 for adjusting the urging force of the urging means 63 are provided. The urging means 63 and the adjusting means 65 constitute a restriction release device.

The fixed plate 62 is configured by bending a plate material, and includes a horizontal first support portion 621 and an inclined second support portion 625. A support base 622 including a pair of opposing support walls is fixed to the first support portion 621. The stopper receiving member 61 is rotatably attached to a pair of support walls of the support base 622.
The stopper receiving member 61 is configured to be bent in an L shape, and as shown in FIG. 24, the receiving portion 611 is arranged along the vertical direction. The receiving portion 611 is configured so as to be able to rotate in a direction to fall indoors, but not to rotate in a direction to fall outdoor.

[Energizing means]
The urging means 63 is attached to the second support portion 625.
The urging means 63 includes a case 631, a contact body 632, a coil spring 633, and a spring retainer 634.
The case 631 is formed by bending a plate material, and is bent from the bottom 6311 fixed to the second support 625, the front wall 6312 bent from the outdoor side of the bottom 6311, and the indoor side of the bottom 6311. The rear wall portion 6313 and the side wall portion 6314 bent from both side surfaces of the bottom portion 6311 are provided.
The contact body 632 is provided so as to be able to advance and retract through the front wall portion 6312. The contact body 632 includes a contact portion 6321 that contacts the receiving portion 611 and a guide plate 6322 that contacts the distal end side of the coil spring 633. The spring retainer 634 is disposed in contact with the rear end side of the coil spring 633.

[Adjustment means]
The adjusting means 65 includes two nuts 652 and a screw 651 screwed into the nut 652, and is attached to the rear wall portion 6313 of the case 631. The tip end of the screw 651 contacts the spring retainer 634. Therefore, when the tightening position of the screw 651 with respect to the nut 652 is changed, the position of the spring retainer 634 in the indoor / outdoor direction, that is, the axial direction of the coil spring 633 can be adjusted. Therefore, the compression state of the coil spring 633 disposed between the contact body 632 and the spring retainer 634 can be adjusted with the screw 651. For this reason, the urging force applied to the contact body 632 can be adjusted by the screw 651. Specifically, as will be described later, the force applied to the stopper receiving member 61 by the biasing force is smaller than the force applied from the stopper member 45 to the stopper receiving member 61 when the wind of the first wind speed hits during negative pressure. It is set to be.

  As shown in FIGS. 23 and 24, the stopper member 45 has the same configuration as that of the second embodiment.

[Operation of restriction device 60]
(Shoji closed position: When the rotation angle is 0 degree)
When the shoji 20 is in the closed position, as in the second embodiment, the stopper member 45 has the abutting portion 488 positioned above the stopper receiving member 61 as shown by the two-dot chain line in FIGS. . For this reason, when the shoji 20 rotates in the opening direction, the regulating device 60 does not prevent the movement.
(Shoji opening position: When the rotation angle is 45 degrees)
The stopper member 45 when the shoji 20 is in the open position and no wind is in a state shown by the solid lines in FIGS. That is, the contact portion 488 of the auxiliary blade stopper 48 is provided such that the position in the height direction is above the receiving portion 611 and the position in the prospective direction is located on the outdoor side of the receiving portion 611.
The stopper member 45 is attached to a predetermined position with respect to the shaft center 321 of the shaft member 31 so as to satisfy the above conditions.

[Operation at positive pressure (closing operation)]
When the shoji 20 of the horizontal axis rotary window 2D is in the fully open state (shoji angle 45 degrees), if the wind blows from the outdoor side to the indoor side, the stopper member 45 is the auxiliary wing 482 as in the second embodiment. Rotates in the direction of moving to the indoor side. For this reason, the contact part 488 of the stopper member 45 does not contact the receiving part 611, and the shoji 20 rotates in the closing direction by the positive pressure as in the second embodiment.

[Operation under negative pressure (rotation restricted state)]
When the shoji 20 of the horizontal axis rotation window 2D is in a fully open state (shoji angle 45 degrees), when wind blows from the indoor side to the outdoor side, as shown in FIG. 25, the auxiliary wing 482 of the stopper member 45 is applied to the auxiliary wing 482. The wind (negative pressure) from the indoor side to the outdoor side is also hit. Therefore, as shown in FIG. 25, the stopper member 45 rotates in the direction in which the auxiliary wing 482 moves to the outdoor side with the horizontal shaft member 47 as the rotation center. For this reason, the contact part 488 of the stopper member 45 contacts the receiving part 611 of the stopper receiving member 61. At this time, the contact body 632 biased by the coil spring 633 is in contact with the receiving portion 611.
For this reason, since the wind speed of the wind is less than the first wind speed, the force applied to the receiving portion 611 by the contact portion 488 is smaller than the force applied to the receiving portion 611 by the contact body 632 and the coil spring 633. The state where the contact portion 488 is in contact with the receiving portion 611 is maintained. Therefore, the shoji 20 cannot be rotated further in the closing direction.

[Operation at negative pressure (Release of rotation restriction state)]
On the other hand, when the wind speed of the wind becomes equal to or higher than the first wind speed and the force applied to the receiving portion 611 by the contact portion 488 is larger than the force applied to the receiving portion 611 by the contact body 632 and the coil spring 633, FIG. As shown in FIG. 5, the contact body 632 moves backward to the indoor side, and the stopper receiving member 61 also rotates. For this reason, the shoji 20 rotates in the closing direction because the position where the contact portion 488 contacts the receiving portion 611 moves to the indoor side.
Further, when the contact body 632 is retracted indoors and the stopper receiving member 61 is rotated, the stopper member 45 is detached from the stopper receiving member 61 and the rotation restriction of the shoji 20 is released as shown in FIG. For this reason, the shoji 20 rotates in the closing direction by the negative pressure wind.

Therefore, in the case of no wind, the horizontal axis rotation window 2D of the fourth embodiment automatically moves the shoji 20 to the open state and enters the natural ventilation state as in the second embodiment.
Further, when a wind (positive pressure) of light wind to weak wind is applied from the outdoor side to the indoor side with respect to the shoji 20, the rotational moment due to the positive pressure is greater than the rotational moment due to the eccentricity of the shaft center 321 and the center of gravity 201. When it is small, the shoji 20 maintains an open state.
Further, when a medium wind to a strong wind (positive pressure) is applied from the outdoor side to the indoor side with respect to the shoji 20, the regulating device 60 does not regulate the rotation of the shoji 20, so that the shoji is similar to the second embodiment. 20 automatically rotates in the closing direction to prevent wind blowing into the room.

On the other hand, when a wind (negative pressure) of light to weak wind is applied from the indoor side to the outdoor side with respect to the shoji 20, the rotational moment due to the negative pressure is greater than the rotational moment due to the eccentricity of the shaft center 321 and the center of gravity 201. When it is small, the shoji 20 maintains an open state.
In addition, when a wind (negative pressure) of about a weak wind to a medium wind is applied from the indoor side to the outdoor side with respect to the shoji 20, the stopper member 45 of the regulating device 60 is received by the stopper as in the second embodiment. Because of the contact with the member 61, the shoji 20 cannot be rotated in the closing direction. For this reason, the shoji 20 remains open, and ventilation (exhaust) is performed by the wind from the indoor to the outdoor.
Furthermore, a wind (negative pressure) of medium to strong wind is applied from the indoor side to the outdoor side with respect to the shoji 20, and the stopper receiving member 61 is driven by the stopper member 45 rather than the force applied to the stopper receiving member 61 by the urging means 63. When the force applied to the lever is large, the contact body 632 moves backward, the stopper receiving member 61 rotates, and the stopper member 45 is disengaged from the stopper receiving member 61, so that the shoji 20 rotates in the closing direction.

In FIG. 28, broken lines 111 and 112 show the results of experiments on the relationship between the wind speed at the negative pressure and the angle of the shoji 20 when the urging force of the urging means 63 by the adjusting means 65 is changed in two stages. In addition, the experimental result of 1st Embodiment which does not provide a control apparatus is shown by the broken line 113, and the experimental result at the time of providing the control apparatus 40 of 2nd Embodiment is shown by the broken line 114. FIG. In these experiments, the same horizontal axis rotation window is used for other conditions such as the distance between the axis 321 and the center of gravity 201.
When the regulating device 40 that regulates the rotation of the shoji 20 at the time of negative pressure is provided, as shown by the broken line 114, the shoji 20 is maintained in the fully open state (angle 45 degrees). If there is no regulating device for regulating the rotation of the shoji 20, as shown by the broken line 113, the shoji 20 rotates in the closing direction when the rotational moment due to the negative pressure exceeds the wind speed at the point 113 </ b> A where the rotational moment due to the center of gravity 201 exceeds. However, the shoji angle also decreases gradually.
Further, when the regulating device 60 that regulates the rotation of the shoji 20 at the negative pressure is provided, as shown by the broken lines 111 and 112, the shoji 20 is maintained in the fully opened state (angle 45 degrees) when the wind speed is low. When the wind speed for retracting the contact body 632 (the wind speed at the point 111A at the broken line 111 and the wind speed at the point 112A at the broken line 112) is exceeded, the stopper member 45 is detached from the stopper receiving member 61 and the shoji 20 rotates in the closing direction. However, the shoji angle also decreases gradually.

[Effect of Fourth Embodiment]
According to such a horizontal axis rotation window 2D of the fourth embodiment, the same operational effects can be achieved by providing the same configuration as the horizontal axis rotation window 2B of the second embodiment.
In addition, since the restriction device 60 is provided with a restriction release device (biasing means 63, adjusting means 65) that releases the stopper when the wind speed during negative pressure increases, the wind speed during negative pressure exceeds a predetermined value. When it reaches, the shoji 20 can be automatically closed. For this reason, excessive ventilation when the wind speed is strong can be prevented.

  Further, since the adjusting means 65 for adjusting the urging force of the urging means 63 is provided, the wind speed when releasing the stopper can be arbitrarily set. For this reason, the natural ventilation plan according to the installation position of the horizontal axis rotation window 2D in the building can be realized, and a good natural ventilation state can be maintained.

[Fifth Embodiment]
Next, a horizontal axis rotation window 2E according to a fifth embodiment of the present invention will be described with reference to FIGS. The horizontal axis rotation window 2E of the fifth embodiment is similar to the horizontal axis rotation window 2C of the third embodiment in that it restricts the rotation of the shoji 20 at the time of positive pressure, but when the positive pressure exceeds a set value, The difference is that a restriction device 70 for releasing the rotation restriction is provided. The restriction device 70 is functionally similar to the restriction device 60 of the fourth embodiment. Accordingly, the same components as those in the third embodiment and the fourth embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate.

  The restriction device 70 of the fifth embodiment includes a stopper member 55 attached to the shoji 20, a fixed plate 62 fixed to the prospective surface of the vertical frame 3, and a stopper attached to the fixed plate 62 so as to be rotatable. A receiving member 71, an urging means 63 for urging the stopper receiving member 71 to the outdoor side, and an adjusting means 65 for adjusting the urging force of the urging means 63 are provided.

  The fixed plate 62 is different from the fixed plate 62 of the fourth embodiment in that the width of the second support portion 625 is short. A support base 622 including a pair of opposing support walls is fixed to the first support portion 621. The support base 622 has the same structure as that of the fourth embodiment although the width is different. The stopper receiving member 71 is rotatably attached to a pair of support walls of the support base 622.

  The stopper receiving member 71 is configured to be bent in an L shape, and as shown in FIG. 30, receiving portions 711 are arranged along the vertical direction. The receiving portion 711 is configured so as to be able to rotate in a direction to fall indoors, but not to rotate in a direction to fall outdoor.

  Since the biasing means 63 and the adjusting means 65 have the same configuration as that of the fourth embodiment, the description thereof is omitted. Moreover, since the stopper member 55 is the structure similar to 3rd Embodiment, as shown to FIG. 29, 30, it attaches | subjects the same code | symbol and abbreviate | omits description.

[Operation of restriction device 70]
(Shoji closed position: When the rotation angle is 0 degree)
When the shoji 20 is in the closed position, as in the third embodiment, the stopper member 55 has the contact portion 588 positioned above the stopper receiving member 71 as shown by a two-dot chain line in FIG. For this reason, when the shoji 20 rotates in the opening direction, the regulating device 70 does not prevent the movement.
(Shoji opening position: When the rotation angle is 45 degrees)
The stopper member 55 when the shoji 20 is in the open position and no wind is in the state shown by the solid lines in FIGS. That is, the contact portion 588 of the auxiliary wing stopper 58 is positioned above the receiving portion 711 in the height direction, and the receiving portion 711 is not disposed in the groove of the contact portion 588.
The stopper member 55 is attached to a predetermined position with respect to the shaft center 321 of the shaft member 31 so as to satisfy the above conditions.

[Operation at positive pressure (rotation restricted state)]
When the shoji 20 of the horizontal axis rotating window 2E is in a fully open state (shoji angle 45 degrees), when wind blows from the outdoor side to the indoor side, as shown in FIG. 31, the auxiliary wing 582 of the stopper member 55 is applied to the auxiliary wing 582. The wind (positive pressure) from the outdoor side to the indoor side is also hit. For this reason, as shown in FIG. 31, the stopper member 55 rotates in the direction in which the auxiliary wing 582 moves to the indoor side with the horizontal shaft member 57 as the rotation center. For this reason, the contact portion 588 of the stopper member 55 moves to the lower side, that is, the stopper receiving member 71 side. Therefore, the receiving portion 711 is disposed in the groove of the contact portion 588 of the stopper member 55. For this reason, when the shoji 20 is rotated in the closing direction by positive pressure, the abutting portion 588 abuts against the stopper receiving member 71. At this time, the contact body 632 biased by the coil spring 633 is in contact with the receiving portion 711.
For this reason, since the wind speed of the wind is lower than the first wind speed, the force applied to the receiving portion 711 by the contact portion 588 is smaller than the force applied to the receiving portion 711 by the contact body 632 and the coil spring 633. The state where the contact portion 488 is in contact with the receiving portion 711 is maintained. Therefore, the shoji 20 cannot be rotated in the closing direction.

[Operation at positive pressure (Release of rotation restriction state)]
On the other hand, when the wind speed of the wind is equal to or higher than the first wind speed and the force applied to the receiving portion 711 by the contact portion 588 is larger than the force applied to the receiving portion 711 by the contact body 632 and the coil spring 633, FIG. As shown in FIG. 5, the contact body 632 moves backward to the indoor side, and the stopper receiving member 71 also rotates. For this reason, the shoji 20 rotates in the closing direction because the position where the contact portion 588 contacts the receiving portion 711 moves to the indoor side.
Further, when the contact body 632 is retracted indoors and the stopper receiving member 71 rotates, the stopper member 55 is detached from the stopper receiving member 71 and the rotation restriction of the shoji 20 is released as shown in FIG. For this reason, the shoji 20 rotates in the closing direction by the positive pressure wind.

[Closed operation under negative pressure]
When the shoji 20 of the horizontal axis rotating window 2E is in the fully open state (shoji angle 45 degrees), when the wind blows from the indoor side to the outdoor side, the stopper member 55 is The auxiliary wing 582 rotates in the direction of moving to the outdoor side with the material 57 as the center of rotation. For this reason, the contact portion 588 moves in a direction away from the receiving portion 711 (upper side). For this reason, even if the shoji 20 rotates in the closing direction due to negative pressure, the contact portion 588 does not come into contact with the stopper receiving member 71, and the shoji 20 moves in the closing direction due to the negative pressure as in the third embodiment. Rotate.

Therefore, in the case of no wind, the horizontal axis rotation window 2E of the fifth embodiment automatically moves the shoji 20 to the open state and enters the natural ventilation state as in the third embodiment.
Further, when a wind (negative pressure) of light wind to weak wind is applied from the indoor side to the outdoor side with respect to the shoji 20, the rotational moment due to the negative pressure is greater than the rotational moment due to the eccentricity of the shaft center 321 and the center of gravity 201. When it is small, the shoji 20 maintains an open state.
Furthermore, when a medium wind to a strong wind (negative pressure) is applied to the shoji 20 from the indoor side to the outdoor side, the regulating device 70 does not regulate the rotation of the shoji 20, so that the shoji 20 is the same as in the third embodiment. 20 automatically rotates in the closing direction to prevent the blowing of wind to the outdoors.

On the other hand, when wind (positive pressure) from light wind to weak wind is applied from the outdoor side to the indoor side with respect to the shoji 20, the rotational moment due to the positive pressure is greater than the rotational moment due to the eccentricity of the shaft center 321 and the center of gravity 201. When it is small, the shoji 20 maintains an open state.
Further, when a wind (positive pressure) of about a weak wind to a medium wind is applied to the shoji 20 from the outdoor side to the indoor side, the stopper member 55 of the regulating device 70 receives the stopper receiving member as in the third embodiment. Since it contacts the member 71, the shoji 20 cannot be rotated in the closing direction. For this reason, the shoji 20 remains open, and ventilation is performed by the wind from the outside to the indoor.
Furthermore, a wind (positive pressure) of medium to strong wind is applied from the outdoor side to the indoor side with respect to the shoji 20, and the stopper receiving member 71 is driven by the stopper member 55 rather than the force applied to the stopper receiving member 71 by the urging means 63. When the force applied to the lever is large, the abutting body 632 moves backward, the receiving portion 711 rotates, and the stopper member 55 is disengaged from the stopper receiving member 71, so that the shoji 20 rotates in the closing direction.

[Effect of Fifth Embodiment]
According to the horizontal axis rotation window 2E of the fifth embodiment as described above, the same operational effects can be achieved by providing the same configuration as the horizontal axis rotation window 2C of the third embodiment.
In addition, since the restriction release device is provided as the restriction device 70 to release the stopper when the wind speed at the positive pressure increases, the shoji 20 is automatically moved when the wind speed at the positive pressure reaches a predetermined value or more. Can be closed. For this reason, excessive ventilation when the wind speed is strong can be prevented.

  Furthermore, since the adjusting means 65 is provided, the wind speed when releasing the stopper can be arbitrarily set. For this reason, the natural ventilation plan according to the installation position of the horizontal axis rotation window 2E in the building can be realized, and a good natural ventilation state can be maintained.

The present invention is not limited to the embodiment described above, and modifications and the like within a range in which the object of the present invention can be achieved are included in the present invention.
In each of the above embodiments, a mechanism for opening and closing the shoji 20 electrically may be added. As the electric opening / closing mechanism, a mechanism conventionally used for a horizontal axis rotary window can be adopted. If such an electric opening / closing mechanism is provided, the horizontal axis rotation window can be forcibly closed and locked even when there is no wind. Furthermore, if a sensor for detecting rain is provided, the horizontal axis rotary window can be forcibly closed when raining, and rain can be prevented from being blown.

The configuration of the hinge device 30 is not limited to the shaft member 31 and the bearing member 35, and may be any configuration as long as the shoji 20 can be rotatably supported with respect to the window frame 10. Moreover, the structure which makes the hinge apparatus 30 adjustable in the position of a prospective direction is not limited to what uses the said uneven | corrugated strip 315,335,355,385. In short, what is necessary is just to be able to adjust only the position of the rotating shaft 320 in the prospective direction without changing the relative positions of the window frame 10 and the shoji 20.
Furthermore, the configuration for adjusting the positional relationship between the window frame 10 and the axis 321 of the rotation shaft 320 of the shoji 20 and the center of gravity 201 of the shoji 20 is not limited to the configuration using the hinge device 30 capable of adjusting the mounting position. For example, a dedicated shaft member and a bearing member whose attachment positions are set in advance may be used for the shoji incorporating the multi-layer glass 25 and the shoji incorporating the single plate glass. However, since the position of the center of gravity 201 of the shoji 20 changes depending on the thickness of the glass 25, the attachment position, and the like, it is preferable to use the hinge device 30 that can be adjusted with a 1 mm pitch or the like as in the above embodiment.
Further, the rotation shaft 320 is fixed so that the position of the rotation shaft 320 cannot be adjusted in the expected direction with respect to the vertical frames 3, 4 and the vertical rods 21, 22, and the axis 321 of the rotation shaft 320 of the window frame 10 and the shoji 20 The positional relationship of the center of gravity 201 may be fixed. For example, in the case of a horizontal axis rotation window in which a single plate glass is incorporated, a shoji and a window frame in which the position of the rotation axis is designed according to the single plate glass may be prepared. Moreover, in the case of the horizontal axis rotation window in which the multilayer glass is incorporated, a shoji and a window frame in which the position of the rotation axis is designed according to the multilayer glass may be prepared.

Further, the configuration of the regulating devices 40, 50, 60, 70 is not limited to the above embodiment. The configurations of the regulating devices 40 and 50 are not limited as long as they can regulate the rotation of the shoji 20 at the time of negative pressure or positive pressure. In particular, the above-mentioned rotation regulation using the wind of the auxiliary wings 482 and 582 is used. Any configuration can be used as long as it can be realized. Furthermore, the regulation devices 60 and 70 may be configured to be able to regulate the rotation of the shoji 20 at a speed lower than a predetermined wind speed and to release the rotation regulation at a speed higher than the predetermined wind speed.
Furthermore, the rotation angle when the shoji 20 is opened may be set with the magnitude of the rotational moment set based on the positional relationship between the shaft center 321 and the center of gravity 201 without providing the door contact member 8.

  Further, the horizontal axis rotary windows 2, 2B, 2C, 2D, and 2E of the respective embodiments may be appropriately combined and installed in a building. For example, on one wall of a building, the horizontal axis rotary window 2B may be used for a high window provided near the ceiling, and the horizontal axis rotary window 2C may be used for a ground window provided near the floor. Moreover, you may provide the horizontal axis rotation window 2,2B, 2C, 2D, 2E in the wall surface which the room of a building opposes, respectively. That is, what is necessary is just to select and install the kind of horizontal axis rotation window according to the natural ventilation plan in a building.
