Description

  The present invention relates to a rotating window that opens and closes by the rotation of a shoji.

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).
The natural ventilation window is a horizontal axis rotation window, and supports the shoji in an eccentric state by disposing the horizontal rotation axis on the upper side of the central position in the vertical direction of the shoji. 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.

By the way, in the natural ventilation window described in Patent Document 1, the position (expected position) of the rotating shaft in the expected direction is appropriately set in the product design, and may be set to the expected position on the outdoor side, for example. In this case, in order to avoid the rotation axis from interfering with the window frame and the shoji, a gap in which the rotation shaft can be arranged is formed in the outdoor frame of the window frame and the shoji. There is a risk that the watertightness may be lowered due to the intrusion of water through the gap, and that the parts such as the rotating shaft and the hinge are exposed to the outside air or rain water, and the life may be shortened due to the adhesion of dust or the like.
In addition, when a large rotating shaft is adopted to give sufficient strength to the rotating shaft that is a connecting portion between the window frame and the shoji, a gap in which the rotating shaft can be arranged must be formed large, There is a risk that the deterioration of the property and the shortening of the service life of the parts will be remarkable.

  The objective of this invention is providing the rotation window provided with the hinge cover which can suppress the lifetime reduction of components while improving watertightness.

  The rotating window of the present invention includes a window frame, a shoji disposed in the window frame, a hinge that pivotally supports the shoji, and a hinge cover that covers an outdoor side of the hinge. A fixed cover attached to a window frame; and a movable cover attached to the shoji. The fixed cover has a fixed inner surface located outside the hinge, and the movable cover It has a movable outer surface that rotates around the pivotal support position of the shoji by the hinge by opening and closing movement, and the movable outer surface overlaps the indoor side in a non-contact state with the fixed inner surface in the opened state of the shoji. It is characterized by being arranged.

According to the rotating window of the present invention, the hinge cover is composed of two members, that is, a fixed cover attached to the window frame and a movable cover attached to the shoji, so that the hinge cover opens and closes with respect to the window frame and the window frame. It is possible to cover the outdoor side of the hinge which is a connecting portion with the shoji. Therefore, it is possible to improve the water tightness by suppressing the intrusion of water from the window frame formed so that the hinge can be placed and the gap outside the door of the shoji, etc., and the parts such as the hinge are exposed to the outside air and rain water, and dust etc. It is possible to suppress a reduction in service life due to adhesion.
In addition, the movable outer surface of the movable cover rotates around the pivotal support position of the shoji by the hinge by opening and closing movement of the shoji, and is located on the indoor side with respect to the fixed inner surface of the fixed cover in the open state of the shoji. The movable outer surface that rotates in the opening / closing movement does not interfere with the fixed inner surface. Therefore, the opening / closing movement of the shoji can be smoothly performed without applying frictional resistance or the like from the hinge cover to the shoji.

In the rotating window of the present invention, the pivot support position of the shoji by the hinge is set in a range from the first pivot support position to the second pivot support position located on the indoor side of the first pivot support position, The movable outer surface has a curvature that is equal to or greater than the curvature of the first rotation trajectory centered on the first pivot support position of the separation point that is located farthest from the first pivot support position in the closed state of the shoji. Preferably, the fixed inner surface is formed along the outdoor side of the second rotation locus centering on the second pivot support position of the separation point in the closed state of the shoji.
According to such a configuration, the movable outer surface of the movable cover has the first rotation locus centered on the first pivot support position of the separation point that is located farthest from the first pivot support position in the closed state of the shoji. Therefore, the rotating movable outer surface does not protrude from the outdoor side of the first rotation trajectory, and the second pivot support position of the aforementioned separation point is formed. The second rotation trajectory centered on the outside of the second projecting locus is not projected and positioned. On the other hand, since the fixed inner surface of the fixed cover is formed along the outdoor side of the second rotation locus centering on the second pivot support position of the separation point described above in the closed state of the shoji, the pivot support of the shoji by the hinge is formed. When the position is set in the range from the first pivot support position to the second pivot support position, the movable outer surface of the movable cover that rotates about the pivot support position may interfere with the fixed inner surface of the fixed cover. Absent. Therefore, even if the pivot support position of the shoji is adjusted in the range from the first pivot support position to the second pivot support position, the common hinge cover can be used.

In the rotating window of the present invention, the hinge cover includes a pair of side plate portions, one side plate portion is formed on the fixed cover, the other side plate portion is formed on the movable cover, and the fixed cover is Continuing on one side plate part and having an opposing inner surface located opposite to the movable outer surface in the closed state of the shoji, the movable cover is continuous with the other side plate portion and in the closed state of the shoji The fixed inner surface of the fixed cover is formed to have a curvature smaller than the curvature of the second rotation locus, and the opposed inner surface is fixed to the fixed inner surface. Preferably, the opposing outer surface is formed with a curvature smaller than that of the movable outer surface, and the opposing outer surface is formed with a curvature smaller than that of the movable outer surface.
According to such a configuration, by forming one side plate portion on the fixed cover, one side portion of the hinge cover can be covered, and by forming the other side plate portion on the movable cover, the shoji The other side part of the hinge cover can be covered while maintaining a state in which the opening / closing movement of the cover is possible, and watertightness can be improved.
In addition, since the opposing inner surface of the fixed cover that is continuous with one side plate portion is formed to have a curvature larger than the curvature of the fixed inner surface, the gap between the fixed cover and the movable cover on one side plate portion side is narrowed. In particular, it is possible to improve water tightness on the side plate portion side.
Furthermore, since the opposing outer surface of the movable cover continuing to the other side plate portion is formed with a curvature smaller than the curvature of the movable outer surface, the gap between the fixed cover and the movable cover on the other side plate portion side is narrowed. In particular, the water tightness on the other side plate portion side can be improved.

In the rotating window of the present invention, the fixed cover is formed with an extended side plate portion extending toward the opposed outer surface, and the opposed surface of the extended side plate portion with respect to the opposed outer surface is determined by the curvature of the fixed inner surface. Is preferably formed with a large curvature.
According to such a configuration, the opposing surface of the extension side plate portion is formed to have a curvature larger than the curvature of the fixed inner surface of the fixed cover, so that the fixed cover and the movable cover on the other side portion of the hinge cover are formed. And the water tightness can be improved.

In the rotating window of the present invention, a rib extending toward the fixed inner surface of the fixed cover is formed on the opposed outer surface, and the opposed surface of the rib with respect to the fixed inner surface has a curvature smaller than the curvature of the opposed outer surface. It is preferable to be formed.
According to such a configuration, since the rib is formed to extend toward the fixed inner surface of the fixed cover, the gap between the fixed cover and the movable cover on the other side of the hinge cover can be narrowed, and the water tightness Can be improved. Moreover, when the above-mentioned extension side board part is formed in the fixed cover, a labyrinth structure can be formed by the extension side board part and a rib, and watertightness can further be improved.

In the rotating window of the present invention, the shoji has a shoji finding piece portion formed along a ridge to which the hinge is attached and located on the indoor side of the hinge, and the window frame is in a closed state of the shoji. A first contact piece provided with a first contact member that comes into contact with the outdoor surface of the shoji finding piece portion; and a second contact material that comes into contact with the indoor surface of the shoji finding piece portion when the shoji is closed. A frame member having a second finding piece portion, a fixed abutting member is attached to the window frame, and a turning abutting member is attached to the shoji finding piece portion, the fixed abutting member. The member has an outdoor part located continuously with the first contact material, an indoor part continuously located with the second contact material, and a connecting part that connects the outdoor part and the indoor part. The pivoting contact member is configured so that the shoji finding piece is placed in the expected direction of the shoji. In the closed state of the shoji, it continuously contacts from the outside of the door through the connecting portion to the inside of the indoor portion, and is rotated by the opening movement of the shoji to rotate the outside of the door, the connecting portion and the chamber. It is preferable to be located away from the inside.
According to such a configuration, the first contact member of the first finding piece portion, the second contact member of the second finding piece portion, and the fixed contact member continuous to the first and second contact members, The rotation abutting member that abuts the outside of the fixed abutting member, the interior of the fixed abutting member, and the connecting portion can be continued. Therefore, even when the position of the first finding piece and the second finding piece is different when using the existing inward window, projecting window structure, and profile, the fixed abutting member and the rotating contact The first and second contact materials can be made continuous by the contact member.
Further, in the opening movement of the shoji, the shoji finding piece part is separated from the first and second abutting members, and the rotating abutting member is separated from the outside of the fixed abutting member, the indoor part and the connecting part, Friction resistance is not given to the shoji from the first and second abutting members, the fixed abutting member, and the rotating abutting member, and the opening movement of the shoji can be performed smoothly. Conversely, when the shoji moves closed, the first and second abutting members are separated from the shoji-finding piece until the shoji reaches the closed position, and the rotation abutting member is fixedly abutting. Since it is separated from the member, the closing movement of the shoji can be performed smoothly.
In this way, the contact members can be made continuous, and the shoji can be opened and closed smoothly.

In the rotating window of the present invention, at least one of the fixed abutting member and the rotating abutting member is configured to have elasticity, and the connecting portion is formed by the hinge in the longitudinal direction of the frame member. A fixed abutting inner surface located on the first finding piece part side of the pivotal support position of the shoji, and the pivot abutting member is a pivoting contact that abuts the fixed abutting inner surface in a closed state of the shoji.

According to such a configuration, the rotation contact outer surface is curved with the position on the indoor side from the pivot support position of the shoji as the center of curvature, so the rotation contact outer surface is centered on the pivot support position of the shoji. When the shoji is moved from the closed state to the open position, it is moved away from the fixed abutting inner surface. Therefore, even if the pivotal support position of the shoji is adjusted outside the center of curvature of the rotating contact outer surface, the rotating contact outer surface does not interfere with the fixed contact inner surface in the opening movement of the shoji. The opening movement can be performed smoothly.
In addition, the center of curvature of the outer surface of the rotating contact is located outside the center of curvature of the inner surface of the fixed contact and is located on the second finding piece side in the longitudinal direction of the frame member, and the outer surface of the rotating contact is fixedly contacting Since it is formed to have a radius of curvature larger than the radius of curvature of the inner surface, the outer surface of the rotating contact approaches the inner surface of the fixed contact and is pressed in the closing movement of the shoji. By this pressing, the fixed abutting inner surface is in close contact with the rotating abutting outer surface, so that watertightness and airtightness can be improved.

In the rotating window of the present invention, the outdoor part has a prospective inner surface formed by extending in the prospective direction of the window frame, which is a surface parallel to the axial direction of the hinge, A prospective outer surface that is parallel to the axial direction of the hinge and extends in the prospective direction of the shoji, and the prospective outer surface is in the longitudinal direction of the shoji finding piece portion in a closed state of the shoji. It is preferable to face and face the prospective inner surface and to be separated from the prospective inner surface by the opening movement of the shoji.
According to such a configuration, in addition to the rotation contact outer surface being pressed against the fixed contact inner surface in the closed state of the shoji, the expected outer surface is the expected inner surface in the longitudinal direction of the shoji finding piece portion in the closed state of the shoji. Therefore, the continuous state on the outdoor side of the shoji finding piece can be improved.

In the rotary window of the present invention, the fixed abutting member is continuous with the inner surface of the fixed abutting and extends to the second finding piece part side from the axial support position of the shoji in the longitudinal direction of the frame member. The pivot contact member is continuous with the pivot contact outer surface, and is longer than the pivot support position of the shoji in the longitudinal direction of the shoji finding piece. The extended outer surface formed to extend to the second finding piece part side, the extended outer surface abuts against the extended inner surface in the prospective direction of the shoji in the closed state of the shoji, It is preferable that the sliding door is positioned away from the extended inner surface by the opening movement of the shoji.
According to such a configuration, in addition to the rotating contact outer surface being pressed against the fixed contact inner surface in the closed state of the shoji, the extended outer surface contacts the extended inner surface in the prospective direction of the shoji, The continuous state on the indoor side of the sliding paper finding piece can be improved. In addition, the extended outer surface is continuous with the rotating contact outer surface, and is formed so as to extend to the second finding piece portion side from the axial support position of the shoji piece in the longitudinal direction of the shoji finding piece portion. In the opening / closing movement of the sliding door, it is not arranged to face the inner surface of the fixed abutment and is separated from the extending inner surface by the opening movement of the shoji. The opening and closing movement can be performed smoothly.

The hinges 30B arranged between the vertical rod 22 and the vertical wall 7 and between the vertical rod 22 and the vertical frame 4 are the same, and the hinge 30A is horizontally reversed. For this reason, the hinge 30A disposed between the vertical frame 3 and the vertical rod 21 will be mainly described below.

The hinge 30 </ b> A includes a shaft member 31 and a bearing member 35 that is rotatably connected to the shaft member 31.
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. In the present embodiment, the shaft member 31 is attached to the vertical frame 3, and the bearing member 35 is attached to the prospective piece portion 211 of the vertical rod 21.

  The shaft member 31 includes a mounting portion 32 screwed to the prospective piece portion 301 of the upper longitudinal member 3B by a plurality of screws 13 shown in FIG. 14, and a shaft formed by expanding the lower end of the mounting portion 32 into a disk shape.

Configured. A rotation shaft 34 is rotatably inserted into the hole of the bearing portion 37.

The pivotal support position of the shoji 20 in the expected direction by the hinge 30 </ b> A can be set to a predetermined position by adjusting the screwing position with respect to the vertical frame 3 and the vertical rod 21 of the mounting portions 32 and 36. That is, as shown in FIG. 10, the pivot support position of the shoji 20 can be set within a range of a distance L from the first pivot support position 15 closer to the outdoor side to the second pivot support position 16 closer to the indoor side. The first pivot support position 15 is set at a position close to the outdoor surface of the vertical shaft 21, and the second pivot support position 16 is set at a position farther to the indoor side than the first pivot support position 15. The first pivot support position 15 is a pivot support position that is set on the outdoor side of the center of gravity position 17 corresponding to the case where the center of gravity of the shoji 20 becomes the center of gravity position 17 closer to the outdoor side. The position 16 is a pivotal support position that is set on the outdoor side of the center of gravity 18 corresponding to the case where the center of gravity of the shoji 20 becomes the center of gravity 18 closer to the room.
Here, the gravity center positions 17 and 18 of the shoji 20 are set to the center position of the shoji 20 in the height direction. Since most of the weight of the shoji 20 is the weight of the face material, the center position of the face material in the height direction coincides with the gravity center positions 17 and 18 of the shoji 20 in the height direction. Further, the positions in the height direction of the shaft support positions 15 and 16 are the same as the gravity center positions 17 and 18.

The shoji 20 of the present embodiment has the center of gravity position 17 closer to the outdoor side because the single plate glass 25 is disposed closer to the outdoor side by the respective flanges 21 to 24.
Corresponding to the center of gravity position 17, each hinge 30 is screwed to a position closer to the outdoor side with respect to the prospective pieces 301, 211, and the pivotal support position of the shoji 20 by the hinge 30 </ b> A is outdoor than the center of gravity position 17. The first pivot support position 15 is set. In this case, the shaft reinforcing portion 33 and a part of the bearing portion 37 are positioned so as to protrude to the outdoor side from the gap between the upper room exterior finding piece 302 and the lower room exterior finding piece 214.

By setting the pivotal support position 15 of the shoji 20 to the position on the outdoor side with respect to the gravity center position 17, a rotational moment is generated in the shoji 20 in the direction in which the upper end moves to the indoor side based on its own weight. The shoji 20 naturally moves to open from the closed position indicated by the solid line in FIG. 3 toward the open position indicated by the two-dot chain line.
Moreover, wind pressure is applied to the shoji 20 in the open state, and the rotational moment that rotates the shoji 20 in the closing direction by the wind pressure is larger than the rotational moment that rotates the shoji 20 in the opening direction based on the weight of the shoji 20 described above. When it becomes, the shoji 20 moves closed from the closed position toward the open position.

As shown in FIGS. 1 and 4, the hinge cover 40 (40 </ b> A, 40 </ b> B) is disposed on the outdoor side of each hinge 30. Each hinge cover 40A is installed on the outdoor side of each hinge 30A, and each hinge cover 40B is installed on the outdoor side of each hinge 30B.
Each hinge cover 40A has the same configuration. The configuration of each hinge cover 40B is the same, and the hinge cover 40A is horizontally reversed. For this reason, hereinafter, the hinge cover 40A that covers the outdoor side of the hinge 30A disposed between the vertical frame 3 and the vertical rod 21 will be mainly described.

  As shown in FIG. 6, the hinge cover 40 </ b> A includes a resin fixed cover 50 attached to the vertical frame 3 and a resin movable cover 60 attached to the vertical rod 21.

As shown in FIG. 9, the fixed cover 50 includes a main body 51, a side plate portion 52 having a substantially half-hen egg shape in a side view, and an attachment portion 53.
The main body 51 has a substantially arc-shaped outer surface 511 and an inner surface 512 (fixed inner surface) that are convexly curved toward the outdoor side.

For this reason, when the movable cover 60 rotates about the first pivot support position 15, the entire outer surface 611 rotates along the first rotation locus 66. Further, when the movable cover 60 rotates about the second pivot support position 16, the outer surface 611 rotates without being positioned protruding from the second rotation locus 67 to the outdoor side (inner surface 512 side).

  In the present embodiment, the inner surface 512 is formed in an arc shape with a radius of curvature 161 centered on the second pivot position 16, and has a constant curvature smaller than the curvature of the second rotation locus 67. For this reason, the inner surface 512 is located along the outdoor side of the second rotation locus 67.

Therefore, the outer surface 611 of the movable cover 60 is fixed regardless of the position of the first pivot support position 15 to the second pivot support position 16. There is no interference with the inner surface 512 of the cover 50. Therefore, the hinge cover 40 does not apply frictional resistance or the like to the shoji 20 and maintains a state in which it can be smoothly opened and closed.

The facing outer surface 624A of the extended edge 624 facing the inner surface 512 of the fixed cover 50 has a curvature smaller than the curvature of the outer surface 611 of the movable cover 60 and the same curvature as the curvature of the second rotation locus 67. Yes. That is, the opposing outer surface 624 </ b> A is formed along the second rotation locus 67. For this reason, the gap between the opposing outer surface 624A and the inner surface 512 of the fixed cover 50 is further narrowed compared to the case where the opposing outer surface 624A has the same curvature as the outer surface 611.
Further, the facing surface 625A of the rib 625 facing the inner surface 512 of the fixed cover 50 is formed to have a curvature smaller than the curvature of the facing outer surface 624A. For this reason, the facing surface 625A is located closer to the inner surface 512 of the fixed cover 50 than the facing outer surface 624A, and further narrows the gap between the fixed cover 50 and the movable cover 60.
Further, the facing surface 513 </ b> A of the extending side plate portion 513 that faces the facing outer surface 624 </ b> A of the extending edge portion 624 is formed with a larger curvature than the inner surface 512 of the fixed cover 50. Therefore, compared to the case where the facing surface 513A has the same curvature as the inner surface 512, the facing surface 513A is positioned closer to the facing outer surface 624A than the inner surface 512, and the gap between the fixed cover 50 and the movable cover 60 is increased. It is narrowing further.
Furthermore, the facing inner surface 524 </ b> A of the extended edge portion 524 facing the outer surface 611 of the movable cover 60 is formed with a larger curvature than the inner surface 512 of the fixed cover 50. For this reason, the gap between the facing inner surface 524A and the outer surface 611 of the movable cover 60 is further narrowed compared to the case where the facing inner surface 524A has the same curvature as the curvature of the inner surface 512.

Furthermore, a screw hole 843 is formed in the rotation chamber inside 84. When the screw 85 is inserted into the screw hole 843 and screwed into the indoor side finding piece 215, the watertight rotating member 81 is attached to the indoor side finding piece 215. In this attached state, with respect to the indoor-side finding piece 215, the rotation chamber exterior 82 is disposed on the outdoor side, and the rotation chamber interior 84 is disposed on the indoor side. Thereby, the watertight rotating member 81 is located across the indoor-side finding piece 215 in the expected direction of the shoji 20.

  The prospective outer surface 821, the watertight rotation outer surface 831, and the extended outer surface 842 are formed as surfaces parallel to the axial direction of the hinge 30.

Here, the watertight fixed inner surface 731 shown by a one-dot chain line in FIG. 12 is in a state where the watertight rotating outer surface 831 is not pressed, and the watertight fixed inner surface 731 shown by the solid line in FIG. It is in a state of being elastically deformed along the watertight rotating outer surface 831.

The center of curvature 733 of the watertight fixed inner surface 731 is at the same height as the height positions of the first pivot support position 15 and the second pivot support position 16, and is positioned indoors in the prospective direction relative to the second pivot support position 16. Is set to
The center of curvature 834 of the watertight rotation outer surface 831 is set at a position on the indoor side of the second pivot support position 16, but is set at a position different from the center of curvature 733. That is, the center of curvature 834 is set at a position on the outdoor side and below (on the side of the lower indoor finding piece 305) with respect to the center of curvature 733. In the XY coordinate system shown in FIG. 13, when the curvature center 733 is the origin (curvature center 733 (0, 0)), the X coordinate value of the curvature center 834 is set to “−0.5”, and the Y coordinate The value is set to “−0.25” (curvature center 834 (−0.5, −0.25)). In FIG. 13, the positive direction in the X coordinate is a direction toward the indoor side, and the negative direction is a direction toward the outdoor side. Further, the positive direction in the Y coordinate is the upward direction, and the negative direction is the downward direction.

In FIG. 12, the third rotation locus 86 centering on the first pivot support position 15 of the watertight rotation outer surface 831 and the fourth rotation locus 87 centering on the second pivot support position 16 of the watertight rotation outer surface 831. It shows.
Since the center of curvature 834 of the watertight rotation outer surface 831 is located on the indoor side with respect to the first pivot support position 15 and the second pivot support position 16, It does not project from the third rotation locus 86. Further, even if it is assumed that the watertight rotating outer surface 831 rotates around the second pivot support position 16, it does not protrude from the fourth rotation locus 87. Therefore, when the pivotal support position of the shoji 20 is set within the range of the distance L from the first pivotal support position 15 to the second pivotal support position 16, the watertight rotation outer surface 831 in the opening movement of the shoji 20 It rotates without interfering with the extended inner surface 711 located on the indoor side with respect to the third rotation locus 86 and the fourth rotation locus 87.

  The prospective outer surface 821 faces and comes into contact with the prospective inner surface 724 in the vertical direction when the shoji 20 is closed. Further, the extended outer surface 842 is located so as to protrude outward from the third rotation track 86 and the fourth rotation track 87, and faces the extended inner surface 711 in the prospective direction of the shoji 20 when the shoji 20 is closed. Are pressed against each other.

  A watertight structure is constituted by the above-described watertight device 70 and each of the airtight members 12 (12A, 12B) mounted on the frames 3 to 6 and the stand 7, and each horizontal axis rotary window 2 in the closed state of each shoji 20 A watertight line that is continuous in all directions is formed in the interior of the room.

[Operation of First Embodiment]
Hereinafter, the opening / closing operation | movement of the continuous window 1 which concerns on 1st Embodiment is demonstrated.
The continuous window 1 is provided with a lock mechanism (not shown), and each shoji 20 is locked in the closed position by this lock mechanism.
When each shoji 20 is in the closed position, each hinge cover 40 covers the outdoor side of the hinge 30A with the fixed cover 50 and the movable cover 60, like the hinge cover 40A shown in FIG.
Further, each watertight device 70 covers the indoor side of the hinge 30 </ b> A with a watertight fixing member 71 and a watertight rotating member 81 as in the watertight device 70 </ b> A shown in FIG. 14.
Further, the prospective outer surface 821, the watertight rotation outer surface 831, and the extended outer surface 842 of the watertight rotating member 81 are in contact with the prospective inner surface 724, the watertight fixed inner surface 731, and the extended inner surface 711 of the watertight fixing member 71. The first airtight material 12A on the side of the finding piece 303 and the second airtight material 12B on the side of the lower indoor finding piece 305 are continuously formed to form a watertight line.

  When the opening of each shoji 20 is made possible by releasing the lock mechanism, the pivot support position 15 of each shoji 20 is located outside the center of gravity position 17, so that each shoji 20 is naturally based on its own weight. Rotate in the opening direction. By this rotation, the shoji 20 moves to the open position (full open position) shown in FIG. 16 through the intermediate open position shown in FIG. When each shoji 20 is arranged in the open position, each shoji 20 is supported by a door stop material (not shown). As a result, each shoji 20 does not rotate further from the open position in the opening direction.

  When the shoji 20 rotates in the opening direction, the movable cover 60 rotates in the opening direction around the pivot position 15 together with the shoji 20. In the rotation in the opening direction, the extended edge 624 and the rib 625 of the movable cover 60 are separated from the inner surface 512 of the fixed cover 50 to the indoor side as shown in FIGS. Further, when the movable cover 60 is rotated in the opening direction, the outer surface 611 of the movable cover 60 is rotated along the first rotation locus 66. Accordingly, the surfaces 611, 624A, and 625A of the movable cover 60 rotate in the opening direction without interfering with the surfaces 512, 513A, and 524A of the fixed cover 50. In the open state of each shoji 20, the outer surface 611 of the movable cover 60 is disposed so as to overlap the indoor side in a non-contact state with the inner surface 512 of the fixed cover 50.

  Further, when the shoji 20 rotates in the opening direction, the watertight rotating member 81 rotates in the opening direction with the shoji 20 as a center around the pivot position 15. In this rotation in the opening direction, the watertight rotation outer surface 831 rotates in the opening direction along the third rotation locus 86. As a result, the prospective outer surface 821, the watertight rotation outer surface 831 and the extended outer surface 842 of the watertight rotating member 81 are replaced with the expected inner surface 724, the watertight fixed inner surface 731 and the extended portion of the watertight fixing member 71, as shown in FIGS. It is spaced apart from the inner surface 711 to the outdoor side. Therefore, the watertight rotating member 81 rotates in the opening direction without interfering with the watertight fixing member 71.

  Next, when wind pressure is applied to each shoji 20 and it rotates in the closing direction from the opening position of the shoji 20 toward the closing position, the movable cover 60 rotates in the closing direction around the pivot position 15 together with the shoji 20. In the rotation in the closing direction, the outer surface 611 of the movable cover 60 rotates along the first rotation locus 66. For this reason, the outer surface 611 rotates to the closed position shown in FIG. 14 while approaching the fixed cover 50. The extended edge 624 and the rib 625 of the movable cover 60 also rotate to the closed position while approaching the inner surface 512 of the fixed cover 50.

  Further, when the shoji 20 rotates in the closing direction, the watertight rotating member 81 rotates in the closing direction with the shoji 20 as a center around the pivot position 15. In the rotation in the closing direction, the watertight rotation outer surface 831 rotates in the closing direction along the third rotation locus 86. As a result, the expected outer surface 821, the watertight rotating outer surface 831 and the extended outer surface 842 of the watertight rotating member 81 approach and come into contact with the expected inner surface 724, the watertight fixed inner surface 731 and the extended inner surface 711 of the watertight fixing member 71, While being pressed, it rotates to the closed position shown in FIG. The prospective outer surface 821, the watertight rotating outer surface 831 and the extended outer surface 842 are pressed against the expected inner surface 724, the watertight fixed inner surface 731 and the extended inner surface 711, so that the watertight fixing member 71 having elasticity undergoes elastic deformation, and is expected. The outer surface 821, the watertight rotating outer surface 831 and the extended outer surface 842 are in close contact with the prospective inner surface 724, the watertight fixed inner surface 731 and the extended inner surface 711. For this reason, high watertightness and airtightness performance are demonstrated.

  Thus, the continuous window 1 opens and closes. At this time, each hinge cover 40 covers the outdoor side of each hinge 30 in the closed state of each shoji 20 and exhibits watertight performance, and the movable cover 60 interferes with the fixed cover 50 when the shoji 20 is opened and closed. Since there is nothing, smooth opening and closing movement can be performed without hindering the operation of each shoji 20. On the other hand, each watertight device 70 forms a watertight line on the indoor side of each hinge 30 in the closed state of each shoji 20, and the watertight rotating member 81 interferes with the watertight fixing member 71 when the shoji 20 is opened and closed. Therefore, smooth opening / closing movement can be performed without interfering with the operation of each shoji 20.

[Effect of the first embodiment]
(1) Since each hinge cover 40 is constituted by two members, that is, each fixed cover 50 attached to the window frame 10 and each movable cover 60 attached to each shoji 20, the connection between the window frame 10 and the shoji 20 The outdoor side of each hinge 30 which is a part can be covered. Therefore, it is possible to improve the water tightness by suppressing the intrusion of water from the gap between the upper room finding piece 302 and the lower room finding piece 214 formed so that a part of the hinge 30 can be arranged. Can be prevented from being shortened due to exposure to outside air or rainwater, and adhesion of dust.
Further, the outer surface 611 of each movable cover 60 is rotated about the pivotal support position 15 of the shoji 20 by each hinge 30 by the opening and closing movement of each shoji 20, and the inner surface 512 of each fixed cover 50 in the open state of the shoji 20. On the other hand, the outer surface 611 that rotates in the opening / closing movement of the shoji 20 does not interfere with the inner surface 512 because it is disposed so as to overlap the indoor side in a non-contact state. Therefore, the opening / closing movement of the shoji 20 can be smoothly performed without applying frictional resistance or the like from the hinge cover 40 to the shoji 20.
(2) The outer surface 611 of the movable cover 60 is a first rotation locus centered on the first pivot support position 15 of the separation point 65 that is located farthest from the first pivot support position 15 in the closed state of the shoji 20. 66, the outer surface 611 that rotates is not positioned so as to protrude outside the first rotation locus 66, and the second pivotal support of the separation point 65 is not provided. The second rotation locus 67 centering on the position 16 does not protrude from the outdoor side. On the other hand, since the inner surface 512 of the fixed cover 50 is formed along the outdoor side of the second rotation locus 67 centering on the second pivotal support position 16 of the separation point 65 in the closed state of the shoji 20, each hinge 30. Is set within a distance L from the first pivot support position 15 to the second pivot support position 16, the movable cover 60 that rotates about the pivot support position is used. The outer surface 611 does not interfere with the inner surface 512 of the fixed cover 50. Therefore, even if the pivot position of each shoji 20 is adjusted in the range from the first pivot position 15 to the second pivot position 16, the common hinge cover 40 can be used.
(3) By forming the side plate portion 52 on the fixed cover 50, one side portion of each hinge cover 40 can be covered, and by forming the side plate portion 62 on the movable cover 60, The other side part of each hinge cover 40 can be covered, maintaining the state which can be opened and closed, and watertightness can be improved.
Further, since the facing inner surface 524A of the extended edge portion 524 that is continuous with the side plate portion 52 is formed to have a curvature larger than the curvature of the inner surface 512 of the fixed cover 50, it is movable with the fixed cover 50 on the side plate portion 52 side. A gap between the cover 60 and the cover 60 can be narrowed, and in particular, water tightness on the side plate portion 52 side can be improved.
Further, since the opposing outer surface 624A of the extended edge 624 continuous with the side plate portion 62 is formed with a curvature smaller than the curvature of the outer surface 611 of the movable cover 60, the movable portion 60 and the fixed cover 50 on the side plate portion 62 side are movable. A gap with the cover 60 can be narrowed, and in particular, water tightness on the side plate portion 62 side can be improved.
(4) The opposing surface 513A of the extended side plate portion 513 is formed to have a curvature larger than the curvature of the inner surface 512 of the fixed cover 50, so that it can move with the fixed cover 50 on the other side of each hinge cover 40. A gap with the cover 60 can be narrowed, and water tightness can be improved.
(5) Since the ribs 625 are formed so as to extend toward the inner surface 512 of the fixed cover 50, the gap between the fixed cover 50 and the movable cover 60 on the other side of each hinge cover 40 can be reduced. Can be improved. Furthermore, the labyrinth structure can be formed by the extended side plate portion 513 and the rib 625, and the water tightness can be further improved.

(6) Each of the airtight members 12 (12A, 12B) mounted on each of the frames 3 to 6 and the stand 7, the watertight fixing member 71, the fixed chamber exterior 72 of the watertight fixing member 71, the fixed connecting portion 73, and the fixed chamber By forming a watertight structure with the watertight rotating member 81 in contact with the inside 74, a continuous watertight line can be formed in the closed state of the shoji 20 and the watertightness can be improved. Therefore, for example, in order to reduce the manufacturing cost by using the existing profile, the existing inward-turning window structure and profile are used in the upper part of the pivot support position 15 and below the pivot support position 15. Even when the existing protruding window structure or shape is used for the side portion, the expected position (indoor / outdoor position) of the upper indoor finding piece 303 and the lower indoor finding piece 305 is different. The watertight line can be made continuous by the watertight device 70.
Further, in the opening movement of the shoji 20, the indoor side finding piece 215 is separated from the first airtight material 12A and the second airtight material 12B, and the watertight rotating member 81 is fixedly connected to the outside of the fixed chamber 72 of the watertight fixing member 71. Since it is separated from the part 73 and the fixed interior part 74, frictional resistance is not given to the shoji 20 from a watertight structure, and the opening movement of the shoji 20 can be performed smoothly. On the contrary, when the shoji 20 is closed and moved, the first airtight material 12A and the second airtight material 12B are separated from the indoor side finding piece 215 until the shoji 20 reaches the closed position. Since the moving member 81 is separated from the watertight fixing member 71, the closing movement of the shoji 20 can be smoothly performed.
Furthermore, since the watertight device 70 can be employed as described above with respect to the existing shape member in which the indoor side finding piece portion 215 is disposed between the upper indoor finding piece portion 303 and the lower indoor finding piece portion 305, the existing shape member is used. Can also be used.
(7) Since the watertight rotation outer surface 831 is curved with the position on the indoor side of the pivot support positions 15, 16 of the shoji 20 as the center of curvature 834, the watertight rotation outer surface 831 has the pivot support position 15 of the shoji 20. When the shoji 20 is moved away from the closed state without being positioned outside the third rotation locus 86 as the center, it moves away from the watertight fixed inner surface 731. Therefore, even if the pivotal support position of the shoji 20 is adjusted within the range of the distance L from the second pivotal support position 16 to the outdoor first pivotal support position 15, the watertight rotating outer surface 831 is watertight in the opening movement of the shoji 20. The opening movement of the shoji 20 can be smoothly performed without interfering with the fixed inner surface 731.
Further, the center of curvature 834 of the watertight rotation outer surface 831 is located on the outer side and below the curvature center 733 of the watertight fixed inner surface 731, and the watertight rotation outer surface 831 has a larger curvature than the radius of curvature 732 of the watertight fixed inner surface 731. Since it is formed with the radius 833, the watertight rotation outer surface 831 approaches the watertight fixed inner surface 731 and is pressed in the closing movement of the shoji 20. By this pressing, the watertight fixed inner surface 731 is elastically deformed and is in close contact with the watertight rotating outer surface 831, so that the watertightness can be further improved.
(8) In addition to the watertight rotating outer surface 831 being pressed against the watertight fixed inner surface 731 in the closed state of the shoji 20, the prospective outer surface 821 is the prospective inner surface in the longitudinal direction of the indoor side finding piece 215 in the closed state of the shoji 20. Since it faces and contacts 724, the watertightness of the indoor side finding piece 215 on the outdoor side can be further improved. Further, since the prospective outer surface 821 is formed to extend outward from the abutting chamber inner surface 822 located on the side of the watertight rotation outer surface 831, the prospective outer surface 821 interferes with the watertight fixed inner surface 731 and the extended inner surface 711. Therefore, the opening / closing movement of the shoji 20 can be performed smoothly.
(9) Since the watertight rotating outer surface 831 is pressed against the watertight fixed inner surface 731 in the closed state of the shoji 20, the extended outer surface 842 faces the extended inner surface 711 in the expected direction of the shoji 20, The water tightness on the indoor side of the inner finding piece 215 can be further improved. In addition, the extended outer surface 842 is continuous with the watertight rotation outer surface 831 and is formed to extend downward from the pivot position 15 of the shoji 20, so that the shoji 20 can be opened and closed with the watertight fixed inner surface 731. Since they are not arranged to face each other and are separated from the extended inner surface 711 by the opening movement of the shoji 20, the extended outer surface 842 does not interfere with the watertight fixed inner surface 731 and the extended inner surface 711, and the shoji 20 is opened and closed. The movement can be performed smoothly.

[Configuration of Second Embodiment]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.
17-20, the double glazing 25A is employ | adopted for the face material of each shoji 20 with respect to the continuous window 1 which concerns on 1st Embodiment in the continuous window 1 which concerns on 2nd Embodiment, The hinge 30 is arranged closer to the indoor side so that the position of the center of gravity of each shoji 20 becomes the position of the center of gravity 18 closer to the indoor side, and correspondingly, the position of the pivot of each shoji 20 becomes the second axis of support 16. ing.
In addition, all the structures except the structure mentioned above in the continuous window 1 which concerns on 2nd Embodiment are the same as the structure of the continuous window 1 which concerns on 1st Embodiment.

The opening / closing operation of the continuous window 1 provided with the double glazing 25A is as follows.
When each of the shojis 20 in the closed position shown in FIG. 18 is opened by releasing a lock mechanism (not shown), the pivot support position 16 of each shoji 20 is located on the outdoor side of the center of gravity position 18, The shoji 20 rotates naturally in the opening direction based on its own weight. By this rotation, the shoji 20 moves to the open position (full open position) shown in FIG. 20 through the intermediate open position shown in FIG. When each shoji 20 is arranged in the open position, each shoji 20 is supported by a door stop material (not shown). As a result, each shoji 20 does not rotate further from the open position in the opening direction.

  When the shoji 20 rotates in the opening direction, the movable cover 60 rotates in the opening direction with the shoji 20 as a center about the pivot position 16. In the rotation in the opening direction, the extended edge portion 624 and the rib 625 of the movable cover 60 are, as shown in FIGS. Rotate along 67. Further, when the movable cover 60 is rotated in the opening direction, the outer surface 611 of the movable cover 60 is rotated along the second rotation locus 67. Accordingly, the surfaces 611, 624A, and 625A of the movable cover 60 rotate in the opening direction without interfering with the surfaces 512, 513A, and 524A of the fixed cover 50. In the open state of the shoji 20, the outer surface 611 of the movable cover 60 is disposed so as to overlap the indoor side in a non-contact state with the inner surface 512 of the fixed cover 50.

  Further, when the shoji 20 rotates in the opening direction, the watertight rotating member 81 rotates in the opening direction around the pivot position 16 together with the shoji 20. In this rotation in the opening direction, the watertight rotation outer surface 831 rotates in the opening direction along the fourth rotation locus 87. Thereby, the prospective outer surface 821, the watertight rotation outer surface 831 and the extended outer surface 842 of the watertight rotating member 81 are replaced with the expected inner surface 724, the watertight fixed inner surface 731 and the extended of the watertight fixing member 71 as shown in FIGS. It is spaced apart from the inner surface 711 to the outdoor side. Therefore, the watertight rotating member 81 rotates in the opening direction without interfering with the watertight fixing member 71.

  Next, when wind pressure is applied to each shoji 20 and it rotates in the closing direction from the open position of the shoji 20 toward the closing position, the movable cover 60 rotates in the closing direction around the pivot support position 16 together with the shoji 20. In the rotation in the closing direction, the outer surface 611 of the movable cover 60 rotates along the second rotation locus 67. Therefore, the outer surface 611 rotates along the indoor side of the inner surface 512 of the fixed cover 50 and returns to the closed position shown in FIG. The extended edge portion 624 and the rib 625 of the movable cover 60 also rotate along the indoor side of the inner surface 512 of the fixed cover 50 and return to the closed position.

  Further, when the shoji 20 rotates in the closing direction, the watertight rotating member 81 rotates in the closing direction with the shoji 20 as a center around the pivot position 16. In the rotation in the closing direction, the watertight rotation outer surface 831 rotates in the closing direction along the fourth rotation locus 87. As a result, the expected outer surface 821, the watertight rotating outer surface 831 and the extended outer surface 842 of the watertight rotating member 81 approach and come into contact with the expected inner surface 724, the watertight fixed inner surface 731 and the extended inner surface 711 of the watertight fixing member 71, While being pressed, it rotates to the closed position shown in FIG. The prospective outer surface 821, the watertight rotating outer surface 831 and the extended outer surface 842 are pressed against the expected inner surface 724, the watertight fixed inner surface 731 and the extended inner surface 711, so that the watertight fixing member 71 having elasticity undergoes elastic deformation, and is expected. The outer surface 821, the watertight rotating outer surface 831 and the extended outer surface 842 are in close contact with the prospective inner surface 724, the watertight fixed inner surface 731 and the extended inner surface 711. For this reason, high watertightness and airtightness performance are demonstrated.

  Thus, the continuous window 1 opens and closes. At this time, each hinge cover 40 covers the outdoor side of each hinge 30 in the closed state of each shoji 20 and exhibits watertight performance, and the movable cover 60 interferes with the fixed cover 50 when the shoji 20 is opened and closed. Since there is nothing, smooth opening and closing movement can be performed without hindering the operation of each shoji 20. On the other hand, each watertight device 70 forms a watertight line on the indoor side of each hinge 30 in the closed state of each shoji 20, and the watertight rotating member 81 interferes with the watertight fixing member 71 when the shoji 20 is opened and closed. Therefore, smooth opening / closing movement can be performed without interfering with the operation of each shoji 20.

According to the continuous window 1 of the second embodiment, similarly to the first embodiment, in the closed state of the shoji 20, the watertight device 70 can continuously form the first airtight material 12A and the second airtight material 12B to form a watertight line. Moreover, since the watertight rotating member 81 is separated from the watertight fixing member 71 in the opening and closing movement of the shoji 20, the opening and closing movement of the shoji 20 can be performed smoothly.
Moreover, according to the continuous window 1 of 2nd Embodiment, since it can rotate appropriately without making the fixed cover 50 and the movable cover 60 interfere, the effect similar to 1st Embodiment can be exhibited, and the shoji 20 There is no need to newly prepare a dedicated hinge cover or the like corresponding to the pivot support position.
