Some joinery as described above have high sealing properties in consideration of airtightness, sound insulation, heat insulation, and the like between two spaces partitioned by the joinery. In such a fitting, there is a risk that a wind blows from the side opposite to the side where the sealing material is provided to the shoji, and a great load acts on the shoji due to the wind pressure, causing the shoji to warp and the like, resulting in a gap. There is. For this reason, in order to ensure a sealing property, the rigidity of a shoji must be improved, and there exists a subject that weight and cost increase.
This invention is made | formed in view of this subject, The place made into the objective is providing the fitting with the small effect | action of the load by a wind pressure etc. while having airtightness.

In order to achieve such an object, the joinery of the present invention is a joinery in which a shoji is provided on a frame body, and the peripheral edge of the shoji that forms a rectangular shape with the frame body is opposed to the prospective direction and the four sides of the shoji At a position along the longitudinal direction, an airtight member is provided on at least one of the frame and the shoji to contact the other and closes between the frame and the shoji. , provided a pressed portion the distance between the by the displacement in the expected direction before Symbol shoji other is pressed is provided on the other to the narrowed position, the spacing is widened position and the other by the displacement that other Each of the separated parts separated from each other, and each of the parts arranged at positions along the longitudinal direction of the four sides of the shoji is either the pressing part or the separated part. With joinery That.

  According to such a fitting, when the shoji is displaced in the prospective direction, the hermetic material having a pressing part that is pressed to the other side and a separated part that is separated from the other part is a part in which the frame and the shoji face in the prospective direction. Is provided. For this reason, for example, even when the shoji is warped due to a pressure difference between one side and the other side of the shoji, air flows from one side of the shoji to the other side of the shoji and the pressure difference is different. Since it is eliminated, it is possible to reduce the load acting on the shoji. In addition, when the pressure difference between the one side and the other side of the shoji is eliminated, it is possible for both the pressing part and the separating part to come into contact and close the frame and the shoji. is there. For this reason, it is possible to provide a joinery that is airtight and has a small load effect due to wind pressure or the like.

In addition , since each of the hermetic materials arranged along the longitudinal direction has a pressing part or a separation part on the four sides of the peripheral edge of the rectangular shoji, the hermetic material is not divided at any of the four sides. . For this reason, it is possible to provide a press part and a separation part, without reducing airtightness.

In the foregoing fittings, side of the two sides along the vertical direction of the four sides of the front Symbol Shoji forms the said pressed portion, with the other side forms the spacing portion, out of the two sides along the lateral direction of the four sides It is desirable that one side forms the pressing portion and the other side forms the separation portion.

  According to such a joinery, one of the two sides along the vertical direction of the four sides of the peripheral edge of the rectangular shoji forms a pressing portion and a separation portion, and one side of the two sides along the left-right direction. Each forms a pressing part and a separating part. For this reason, since the length of the pressing part and the separation part are equal at the peripheral edge of the shoji, when the shoji warps due to the pressure difference between the one side and the other side of the shoji, air is circulated in a well-balanced manner. It is possible to eliminate the pressure difference.

Such a fitting, before Symbol No one has the pressing portion of the two sides along the vertical direction of the four sides of the sash and lateral direction along two sides, it is desirable that the other person forms the spacing portion.

  According to such a joinery, since the members that form the upper and lower sides and the members that form the two left and right sides are the same member, it is possible to reduce the types of members, and it is possible to manage the members and assemble the frame. Easy. In addition, when the members used for dividing the members forming two sides along the vertical direction and the members forming two sides along the left-right direction into the pressing portion and the separating portion, respectively, the mounting portion of the airtight member is used as each member. However, if the members that form the two upper and lower sides and the members that form the two left and right sides are the same member, one mounting portion for the airtight material may be provided for each member. For this reason, it is possible to reduce the size of the member.

Such joinery,
It is desirable that the shoji is supported by the frame so as to form a gap that communicates two spaces partitioned by the shoji between the lower end of the shoji and the frame.

  According to such a joinery, the shoji is supported by the frame and can form a gap between the lower end of the shoji and the frame so as to communicate the two spaces partitioned by the shoji. When the shoji is warped due to the pressure difference between the two spaces, it is possible to eliminate the pressure difference by circulating air under the shoji.

  In such a joinery, it is preferable that the gap is formed by the shoji being supported by a plurality of support members that are arranged with a space between the lower end and the frame.

  According to such a joinery, the shoji can be supported in a more stable state since the lower end of the shoji is supported by the support member and the frame. In addition, since a plurality of support members are arranged at a distance from each other, when the shoji is warped due to a pressure difference between the two spaces partitioned by the shoji, the support member is placed under the shoji from between the support members. It is possible to eliminate the pressure difference by circulating air.

  Such a joinery is preferably provided together with another joinery different from the joinery at an indoor / outdoor boundary, and the joinery is preferably disposed on the indoor side of the other joinery.

  According to such a joinery, since the other joinery is provided on the outdoor side, the joinery arranged on the indoor side of the other joinery is not suitable for the shoji due to the pressure difference between the two spaces partitioned by the shoji. Since air is circulated when warping occurs to eliminate the pressure difference, the strength and airtightness are not required as high as other fittings arranged on the outdoor side. For this reason, it is possible to provide a lightweight and inexpensive fitting.

In such a joinery, it is preferable that the frame body is provided with a biasing member that biases the shoji in the expected direction.
According to such a fitting, since the shoji is urged in the expected direction by the urging member provided on the frame, for example, even if the shoji is warped, the shoji is framed by the urging member. It is possible to close the space between the frame body and the shoji by pressing the body side.

And is pressed against the outdoor surface of the indoor protruding plate-like portion 13 c of the inner horizontal frame member 13.

  At the four corners of the inner frame 11 to which the FIX shoji 20 is attached, the vertical airtight member 14 provided on the left and right inner vertical frame members 12 and the horizontal members provided on the upper and lower reed members 22 respectively. An airtight material block 27 that connects the vertical airtight material 14 and the horizontal airtight material 14 is provided so that the state of the airtight material with the airtight material 14 is connected over the entire circumference. As shown in FIGS. 3 and 4, each of the airtight material blocks 27 is in contact with the end portions 14 c of the vertical airtight materials 14 adjacent to each other and the end portions 14 c of the horizontal airtight materials 14. 27 a, and is formed so as to block between the corner portion where the vertical rod member 21 and the horizontal rod member 22 are joined and the inner frame body 11.

  The FIX 20 has an air pressure difference between two spaces partitioned by the FIX shoji 20 in the prospective direction, that is, the space between the outer window joiner 1 and the FIX shoji 20 and the space on the indoor side of the FIX shoji 20. As a result, warpage occurs in the FIX shoji 20 and part of the left and right vertical saddle members 21 and the upper and lower horizontal joists 22 are displaced in the prospective direction, or the FIX shoji 20 moves in the prospective direction, so that the FIX shoji 20 When the whole is displaced, it works to eliminate the pressure difference.

  For example, if the pressure in the space between the exterior window joiner 1 and the FIX shoji 20 is higher than the space on the indoor side of the FIX shoji 20, the FIX shoji 20 warps so as to swell indoors or the FIX shoji 20 Moves indoors. As a result, the upper and lower horizontal bar members 22 are pushed indoors, so that the elastic portion 14b of the airtight member 14 provided on the upper and lower horizontal bar members 22 protrudes from the inner horizontal frame member 13 into the room as shown in FIG. The plate-like portion 13c is more strongly pressed against the outdoor side surface. On the other hand, the left and right vertical fence members 21 are also pushed to the indoor side, but the left and right vertical fence members 21 are displaced in a direction away from the left and right inner vertical frame members 12, and therefore the airtight material 14 provided on the left and right vertical fence members 21. As shown in FIG. 6, a gap is generated between the elastic portion 14 b and the outdoor side surface of the vertical saddle member 21. At this time, air moves from the outdoor side of the FIX shoji 20 which is the high pressure side to the indoor side, the pressure difference is eliminated, the displacement due to the warp or movement of the FIX shoji 20 is eliminated, and the entire circumference of the FIX shoji 20 is again It will be in the state obstructed over. At this time, when the pressure in the space between the outer window joiner 1 and the FIX shoji 20 is higher than the space on the indoor side of the FIX shoji 20, the airtight material 14 provided on the upper and lower reed members 22 is pressed. The air-tight material 14 provided on the left and right vertical rod materials 21 corresponds to the separated portion.

  Further, when the pressure in the space between the outer window joinery 1 and the FIX shoji 20 becomes lower than the space on the indoor side of the FIX shoji 20, the FIX shoji 20 warps so as to bulge to the outdoor side, or the FIX shoji 20 Moves to the outdoor side. As a result, the left and right vertical rod members 21 are pushed to the outdoor side, so that the elastic portions 14b of the airtight member 14 provided on the left and right inner vertical frame members 12 are pressed more strongly as shown in FIG. On the other hand, the upper and lower reed members 22 are also pushed to the outside of the room, but the upper and lower reed members 22 are displaced in the direction away from the indoor projecting plate-like portion 13c of the upper and lower inner horizontal frame members 13, so As shown in FIG. 8, a gap is generated between the elastic portion 14 b of the airtight member 14 provided on the inner side frame member 13 and the outdoor side surface. At this time, the air moves from the indoor side of the FIX shoji 20 to the outdoor side, that is, from the high pressure side to the indoor side, the pressure difference is eliminated, the displacement due to the warp or movement of the FIX shoji 20 is eliminated, and the FIX It will be in the state obstruct | occluded over the perimeter. At this time, since both ends of the lower end of the FIX shoji 20 are supported by the support members 26, air moves from the high pressure side to the indoor side between the two support members 26 even under the FIX shoji 20, causing a pressure difference. Is resolved. At this time, when the pressure in the space between the outer window joiner 1 and the FIX shoji 20 is lower than the space on the indoor side of the FIX shoji 20, the airtight material 14 provided on the left and right inner vertical frame members 12 is pressed. The airtight material 14 provided on the upper and lower reed members 22 corresponds to the part and corresponds to the separated part.

  According to the inner window joinery 10 of the present embodiment, when the FIX shoji 20 is displaced to either the outdoor side or the indoor side in the prospective direction, a pressing part that is pressed to the other side and a separating part that is separated from the other part Are provided on the vertically projecting plate-like portion 12b and the indoor projecting plate-like portion 13c in which the inner frame 11 and the casing 23 of the FIX shoji 20 are opposed in the prospective direction. For this reason, warping or the like occurred in the FIX shoji 20 due to a pressure difference between the two spaces partitioned by the FIX shoji 20, that is, the space between the outer window joinery 1 and the FIX shoji 20 and the space inside the FIX shoji 20 Even in this case, the air flows between the two spaces from the separated portion and the pressure difference is eliminated, so that the load acting on the FIX shoji 20 can be reduced.

  In addition, when the pressure difference between the space between the outer window joiner 1 and the FIX shoji 20 and the space on the indoor side of the FIX shoji 20 is eliminated, the airtight material 14 provided on the left and right inner vertical frame members 12. In addition, the airtight material 14 provided on the upper and lower reed members 22 can be in contact with each other to close the space between the inner frame 11 and the FIX shoji 20. For this reason, it is possible to provide the joinery 10 that is airtight and has a small load effect due to wind pressure or the like.

  In addition, since the airtight members 14 arranged along the longitudinal direction on the four sides of the peripheral edge of the casing 23 of the rectangular FIX shoji 20 form a pressing portion or a separation portion, the airtight member 14 has four sides. It is provided without being divided at any of the sides. For this reason, it is possible to provide a press part and a separation part, without reducing airtightness.

  In addition, one of the vertical saddle member 21 along the vertical direction of the four sides of the FIX shoji 20 and the horizontal saddle member 22 along the left-right direction forms a pressing portion, and the other forms the separation portion. The saddle members 21 and the horizontal saddle members 22 along the left-right direction are the same member. For this reason, it is possible to reduce the kind of member, and management of a member and assembly of a frame are easy. In addition, when the saddle material used for dividing the vertical saddle member 21 along the vertical direction and the horizontal saddle member 22 along the left and right direction into the pressing portion and the separation portion, respectively, an airtight material fitting portion is used for each member. Although it is necessary to provide two places at a time, if the left and right vertical saddle members 21 and the upper and lower two horizontal saddle members 22 are the same saddle member, an airtight material fitting portion may be provided at one place for each member. For this reason, it is possible to reduce the size of the vertical gutter material 21 and the horizontal gutter material 22.

  The inner window joinery 10 is structured to support the lower end of the FIX shoji 20, but the longitudinal direction of the lower inner horizontal frame member 13 is between the FIX shoji 20 and the lower inner horizontal frame member 13. By interposing support members 26 that are spaced apart from each other at both ends of the FIX door 20, the FIX door 20 is caused by a pressure difference between the space between the outer window joiner 1 and the FIX door 20 and the space inside the door of the FIX door 20. Even if warping occurs, it is possible to eliminate the pressure difference by circulating air below the FIX shoji 20. At this time, the arrangement of the support member 26 is not limited to the both ends of the FIX shoji 20, and if the FIX shoji 20 can be supported in an appropriate posture, the support member 26 shorter than the width of the FIX shoji 20 is attached to the FIX shoji 20. A plurality of them may be arranged at appropriate intervals in the width direction, or may be supported by one support member 26 so that air is circulated under the FIX shoji 20 to eliminate the pressure difference.

  In addition, the horizontal saddle member 22 on the lower side of the FIX shoji 20 is placed on the inner horizontal frame member 13 in contact with the support member 26 over the entire length, and the FIX shoji 20 in the width direction of the inner horizontal frame member 13 is fixed. In part, the space between the outer window joiner 1 and the FIX shoji 20 and the indoor side of the FIX shoji 20 when the airtight member 14 is separated between the lower laying material 22 and the inner frame material 13. A recess or the like may be provided in order to form a gap communicating with the other space. At this time, the support member 26 is not necessarily provided.

  Moreover, in this embodiment, although it was set as the structure which supports the lower end of the FIX shoji 20, for example, a restriction pin is provided from the outer peripheral end of the vertical outer plate portion of the vertical shovel of the FIX shoji 20 to the vertical inner plate portion side. By providing a crossing wall part, forming a notch part into which the restriction pin is inserted in this wall part, and when the FIX shoji is attached to the inner frame, the edge of the notch part is supported by the restriction pin The FIX shoji is supported so that the lower end of the FIX shoji is located above the lower inner frame member, and the space between the outer window joiner 1 and the FIX shoji 20 and the room of the FIX shoji 20 It is good also as a structure by which inner space is connected. In this case, the space between the outer window joiner 1 and the FIX shoji 20 and the space on the indoor side of the FIX shoji 20 in a wider area than the case where the lower end of the FIX shoji 20 is supported by the lower inner horizontal frame member 13. It is possible to communicate.

  In addition, as in the above-described embodiment, since it is not required to be as strong and airtight as the outer window joiner 1 by being used as an inner window joiner provided inside the outer window joiner 1, it is a lightweight and inexpensive joiner. 10 can be provided.

  In the above embodiment, the four airtight members provided on the left and right vertically projecting plate-like portions 12b and the upper and lower indoor projecting plate-like portions 13c facing the inner frame 11 at the peripheral edge of the rectangular FIX shoji 20 14, an example in which the airtight members 14 provided on the left and right vertically projecting plate-like portions 12b or the airtight members 14 provided on the upper and lower indoor projecting plate-like portions 13c form a pressing portion or a separating portion is described. However, it is not limited to this. For example, one of the airtight members 14 provided on the left and right vertically projecting plate-like portions 12b is a pressing portion and the other is a separated portion, and one of the airtight members 14 provided on the upper and lower indoor protruding plate-like portions 13c. It is good also considering a pressing part and the other as a separation part. In this case, since the length of the pressing portion and the separation portion becomes equal at the peripheral edge of the FIX shoji 20, the space between the outer window joiner 1 and the FIX shoji 20 and the space on the indoor side of the FIX shoji 20 When the FIX shoji 20 warps due to a pressure difference or the like, it is possible to eliminate the pressure difference by circulating air in a well-balanced manner.

  Moreover, the space | interval part of the airtight material 14 should just be provided in at least one place of the perimeter which opposes the inner frame 11 in the peripheral part of the FIX shoji 20, for example, the periphery of the FIX shoji 20 which makes a rectangular shape A part of one of the four sides may be a separated part.

  Moreover, although the said embodiment demonstrated the example in which the airtight material 14 was provided in any one of the site | parts where the inner frame 11 and the FIX shoji 20 oppose in a prospective direction, the inner frame 11 and the FIX shoji were demonstrated. 20 may be provided with airtight members 14 respectively.

  The fitting of the present invention eliminates the pressure difference by flowing air between the two spaces when the pressure difference is generated between the outdoor space and the indoor space. Since the acting load can be kept small, it is possible to attach even a large size shoji. However, in the case of a large shoji, the length of each of the shochus that make up the kite increases, so that the shochu will be warped during the shoji manufacturing stage, and when the shoji is attached to the building, There is a risk that a gap will be formed.

For this reason, in order to maintain airtightness even when a shoji that has a large size and warpage is attached, in addition to the configuration of the above embodiment, a place where warpage of the saddle material is likely to occur is in the prospective direction. An urging member that urges and presses the frame body may be provided.
A modification of the above-described embodiment provided with an urging member that suppresses warping of the shoji that has warped in the manufactured state will be described below. In the following description, the same components as those in the above embodiment are denoted by the same reference numerals in the drawings, and the description thereof is omitted.

  As shown in FIGS. 9 and 10, the leaf springs 30 as urging members that press the upper and lower horizontal members 22 of the FIX shoji 20 from the outdoor side toward the indoor side in the expected direction are the upper and lower horizontal members 22. Are provided at substantially the center in the longitudinal direction.

  The plate spring 30 is formed by the outer horizontal frame contact portion 13a, the outdoor protruding plate-like portion 13b, and the indoor protruding plate-like portion 13c in the upper and lower inner horizontal frame members 13, and the upper end portion of the upper horizontal flange member 22 or Lower end portions of the lower horizontal flange member 22 are provided in the flange insertion portions 13e into which the lower horizontal flange members 22 are respectively inserted, the lower surface of the outer horizontal frame contact portion 13a in the upper inner horizontal frame member 13, and the lower inner horizontal frame member 13 is fixed to the upper surface of the outer horizontal frame abutting portion 13a with screws.

  The leaf springs 30 fixed to the upper and lower inner horizontal frame members 13 are the same member, and are fixed to the upper and lower inner horizontal frame members 13 by reversing the vertical direction. For this reason, the following description of the leaf spring 30 will be described using the leaf spring 30 provided on the upper inner frame member 13 as an example. That is, in the following description, the leaf spring 30 attached to the lower inner horizontal frame member 13 is different from the upper leaf spring 30 only in the vertical direction.

  The upper leaf spring 30 includes a fixed plate portion 30a screwed to the outer horizontal frame contact portion 13a of the upper inner horizontal frame member 13 and a first vertical extending from an outer edge of the fixed plate portion 30a. A plate portion 30b, a first inclined portion 30c inclined from the lower edge of the first vertical plate portion 30b toward the indoor side, a second vertical plate portion 30d suspended from the lower edge of the first inclined portion 30c, A second inclined portion 30e that is inclined toward the outdoor side from the lower edge of the second vertical plate portion 30d, and provided at the tip of the second inclined portion 30e, along the outdoor protruding plate-like portion 13b by deformation of the leaf spring 30. And a sliding portion 30f that slides.

The fixed plate portion 30a is brought into contact with a flat portion on the lower surface of the outer horizontal frame contact portion 13a of the upper inner horizontal frame member 13 except for a portion where the outdoor waterproofing material 19 is provided. Is formed. For this reason, in the state in which the leaf spring 30 is fixed, the first vertical plate portion 30b that is suspended from the outdoor edge of the fixed plate portion 30a is spaced apart from the outdoor protruding plate-like portion 13b so as to be substantially parallel to the outdoor spring. It is facing away.
Further, in a state where the leaf spring 30 is fixed, the first vertical plate portion 30b and the second vertical plate portion 30d are formed so as to form substantially parallel surfaces with an interval in the prospective direction.

  The first inclined portion 30c is inclined so as to be gradually spaced downward from the outdoor protruding plate-like portion 13b, and the second inclined portion 30e is gradually lowered downward, the outdoor protruding plate-like portion 13b. It is inclined so that the interval between and becomes narrower. And the lower end of the 2nd inclination part 30e is extended to the outdoor side from the 1st vertical board part 30b, and the sliding part 30f provided in the lower end is contact | abutted to the outdoor protrusion plate-shaped part 13b. Is formed.

  As shown in FIG. 11, the FIX shoji 20 is attached in a steadily manner with the leaf springs 30 fixed to the upper and lower inner horizontal frame members 13. More specifically, the FIX shoji 20 is tilted from the indoor side so that the upper part is located on the outer side of the lower part, and is lifted upward, and the lateral outer plate part 22a and the lateral inner plate part 22b of the upper lateral member 22 are lifted upward. The indoor protruding plate-like portion 13c of the upper inner horizontal frame member 13 is inserted between the two. At this time, the upper end portion of the lateral outer plate portion 22a of the upper horizontal flange member 22 presses the second inclined portion 30e of the leaf spring 30, and the pressed leaf spring 30 has a sliding portion 30f with an outdoor protruding plate-like portion. It is elastically deformed so as to extend while sliding along 13b.

  By lifting the FIX shoji 20 further upward, the upper end portion of the lateral outer plate portion 22a slides on the second inclined plate portion 30e of the leaf spring 30, and then passes through the second vertical plate portion 30d while sliding. It moves to the space above the inclined part 30c.

  Thereafter, the lower part of the FIX shoji 20 is arranged so that the indoor protruding plate-like portion 13c of the lower inner horizontal frame member 13 is located between the horizontal outer plate portion 22a and the horizontal inner plate portion 22b of the lower horizontal rib member 22. The lower end portion of the lateral outer plate portion 22a of the lower laying material 22 is guided to the second inclined portion 30e while pressing the second inclined portion 30e of the leaf spring 30 by moving it downward to the outdoor side. The lower end portion of the lateral outer plate portion 22 a of the lower lateral flange member 22 is placed on the upper surface 26 a of the support member 26 and attached to the inner frame body 11.

  In a state in which the FIX shoji 20 is mounted on the inner frame body 11, when the upper and lower horizontal member 22 is not warped, the second vertical plate portion 30 d of the upper and lower leaf springs 30 is connected to the upper and lower horizontal member 22. The lateral outer plate portions 22a of the upper and lower horizontal ribs 22 are urged and pressed toward the indoor protruding plate-like portion 13c. For this reason, when there is no pressure difference between the space between the outer window joinery 1 and the FIX shoji 20 and the space inside the FIX shoji 20 or when the pressure difference is small, the FIX shoji The space between 20 and the inner frame 11 is closed over the entire circumference. At this time, even if the upper and lower horizontal support members 22 are warped at the time of manufacture or the like, the FIX screen 20 is pressed against the inner horizontal frame member 13 by the leaf spring 30 so that the entire periphery of the FIX screen 20 is covered. It is blocked and airtightness is maintained.

  The elastic force generated by the leaf spring 30 is such that the pressure in the indoor space of the FIX shoji 20 is greater than the set desired value than the pressure in the space between the outer window joiner 1 and the FIX shoji 20. In such a case, the FIX shoji 20 is set to move to the outdoor side. As a result, when the space on the indoor side of the FIX shoji 20 becomes larger than the set pressure difference than the space between the outer window joiner 1 and the FIX shoji 20, the FIX shoji 20 presses the leaf spring 30. Since the upper and lower horizontal bar members 22 are displaced in the direction away from the upper and lower inner horizontal frame members 13 against the pressure, the elastic portion of the airtight member 14 provided on the upper and lower horizontal bar members 22 as shown in FIG. A gap is generated between 14b and the outdoor side surface of the inner horizontal frame member 13. Then, air flows through the generated gap, the pressure difference is eliminated, and the load acting on the FIX shoji 20 can be reduced.

  In the above-described modified example, the example in which the leaf springs 30 that press the upper and lower horizontal bar members 22 in the expected direction from the outdoor side toward the indoor side is described, but the left and right vertical bar members 21 are connected from the indoor side to the outdoor side. You may provide the leaf | plate spring pressed to a prospective direction toward. For example, when the FIX shoji 20 is mounted on the inner frame 11, a leaf spring is attached to the inner vertical frame member 12 so as to enter the pin insertion portion 21e, and the vertical outer plate 21a is moved from the indoor side to the outdoor side. It is good also as a structure pressed in a prospective direction toward. In this case, even if the left and right vertical saddle members 21 are warped at the time of manufacture, the FIX shoji 20 is pressed against the left and right inner vertical frame members 12 by the leaf springs. The entire circumference is closed and airtightness is maintained.

  And when the pressure of the space between the exterior window joiner 1 and the FIX shoji 20 becomes larger than the set desired value than the pressure of the indoor space of the FIX shoji 20, the FIX shoji 20 is moved to the indoor side. Set to move. Thereby, when the pressure of the space between the exterior window joinery 1 and the FIX shoji 20 becomes larger than the set desired value than the pressure of the indoor space of the FIX shoji 20, the FIX shoji 20 The left and right vertical rod members 21 are displaced in a direction away from the left and right inner vertical frame members 12 against the pressing force of the leaf springs, so that the elastic portion 14b of the airtight material 14 provided on the left and right inner vertical frame members 12 is used. And a gap is formed between the vertical outer plate portion 21a and the outdoor side surface. Then, air flows through the generated gap, the pressure difference is eliminated, and the load acting on the FIX shoji 20 can be reduced.

  In the present modification, the example in which the leaf springs 30 are provided only on the upper and lower inner horizontal frame members 13 or only on the left and right inner vertical frame members 12 has been described. And the left and right inner vertical frame members 12 may be provided.

  In the above-described embodiment, the example in which the leaf spring 30 as the urging member is arranged at the substantially center in the longitudinal direction of the upper and lower inner horizontal frame members 13 has been described. Alternatively, a plurality of leaf springs may be arranged at intervals. Further, the attachment of the leaf spring 30 is not limited to screw fixing, and may be adhesion or engagement with a shape member. Further, the shape of the leaf spring is not limited to the shape described in the present embodiment, and the frame members 21 and 22 of the FIX shoji 20 can be pressed against the frame members 12 and 13 and the space on the indoor side of the FIX shoji 20 can be If the pressure is larger than the set desired value than the pressure of the space between the outer window joiner 1 and the FIX shoji 20, the shape can be elastically deformed to provide a separation part of the airtight material 14 I do not care.

  Moreover, in the said embodiment, although the biasing member which presses a saddle material to the inner horizontal frame material 13 side was made into the leaf | plate spring 30, it deform | transforms elastically and presses and attaches the saddle material to the inner horizontal frame material 13 side. Any member provided with a coil spring or rubber may be used as long as it can guide the shoji.

  In the said embodiment, although demonstrated taking the inner window joinery 10 provided with the FIX shoji 20 as an example, it is not restricted to this. For example, as shown in FIGS. 13 and 14, it may be a sliding window fitting 100 provided with an inner impingement 101 and an outer imperial 102. In this case, for example, a chamber is inserted along the rail 104a between the fin-shaped rail 104a provided in the inner frame 104 and the upper and lower flanges 103a. An airtight member 14 is provided so as to come into contact with the rail 104a from the outside, and is inserted into the door-end fence 105 of each shoji 101, 102, and the fin-shaped insertion piece 104b and the door-end fence 105 included in the inner frame body 104 are provided. In between, the airtight material 14 is provided so that it may contact | abut to the insertion piece 104b from the indoor side along the insertion piece 104b. As a result, when warpage occurs in the inner shoji 101 and the outer shoji 102 due to a pressure difference between the space between the outer window joinery 1 and the inner window joiner 10 and the space on the indoor side of the inner window joinery 10, air is discharged. It is possible to eliminate the pressure difference by circulation. At this time, in a state in which the inner impingible element 101 and the outer impoverishment element 102 are closed, a separation portion of the airtight member 14 is provided at least at one place on the entire periphery facing the inner frame body 104 at the peripheral edge portions of the inner impingible element 101 and the outer imperial element 102. It does not matter as long as it is provided. Moreover, the shoji may be a sliding door shoji that opens and closes in addition to the FIX shoji and the sliding shoji. The shape of the shoji is not limited to a rectangular shape, and may be a shape other than a rectangular shape such as a circular shape or a triangular shape.

  In addition, the said embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and it is needless to say that the present invention includes equivalents thereof.
