[0008] Embodiments of this disclosure will be described in detail below with reference to the drawings. The fixture of this disclosure is a fixed window 1 that does not open or close to an opening in a building. The fixed window 1 is installed in a rectangular opening in a building.

[0009] As shown in Figures 1 and 2, the fixed window 1 has a window frame 2 that extends around all four sides of the opening in the building. The window frame 2 is formed by framing an upper frame 3 and a lower frame 4 that extend in the left-right direction, and left and right vertical frames 5 that extend in the up-down direction, in a rectangular shape. A facing material 6 is housed on the inner side of the window frame 2. In this embodiment, the facing material 6 is made of double-glazed glass, but is not limited to this. A rectangular frame 7 is attached to the interior end of the window frame 2, extending around all four sides. On the interior side of the window frame 2, a rectangular frame-shaped opening and closing member 8 is provided on the interior side of the facing material 6 and the exterior side of the frame 7, extending around all four sides.

[0010] Here, we will explain the directions indicated by the arrows in each figure. The X1-X2 direction indicates the interior-exterior direction of FIX window 1. The X1 direction is the exterior side, and the X2 direction is the interior side. The Y1-Y2 direction indicates the vertical direction of FIX window 1. The Y1 direction is the vertical upward direction, and the Y2 direction is the vertical downward direction. The X1-X2 direction is also called the depth direction of FIX window 1. The surface arranged along this depth direction is the depth surface of FIX window 1. The surface arranged perpendicular to the depth direction and facing the exterior and interior sides is the visible surface of FIX window 1. Figure 1 is a front view of FIX window 1 as seen from the exterior side. In FIX window 1, the left-right direction refers to the horizontal direction along the visible surface.

[0011] In the fixed window 1 of this embodiment, of the four sides of the window frame 2, the upper frame 3 and the left and right vertical frames 5 have a double structure formed by inner frames 31, 51 and outer frames 32, 52, respectively, which are made of plate material extending in the longitudinal direction of each side of the window frame 2.

[0012] As shown in Figures 3, 6, and 7, the inner frame 31 of the upper frame 3 has a panel housing section 311 that cradles and accommodates the upper edge of the panel 6, and an extension section 312 that extends from the panel housing section 311 toward the interior in the depth direction. The panel housing section 311 and the extension section 312 of the inner frame 31 are integrally formed. The upper edge of the panel 6 is housed in the panel housing section 311. The panel 6 is supported within the panel housing section 311 by a trim piece 313 positioned on the interior side. The panel 6 is omitted in Figures 6 and 7.

[0013] The inner frame 31 has an outdoor side wall portion 314 that forms the outdoor side finding surface of the inner frame 31. The outdoor side wall portion 314 is arranged to face the outdoor side and protrudes upward from the outer surface 311a of the face material accommodating portion 311. A sealing material 315 made of rubber or the like is attached to the indoor side surface of the upper end portion 314a of the outdoor side wall portion 314 over the length direction of the inner frame 31.

[0014] The inner frame 31 has an indoor side wall portion 316 that forms the indoor side finding surface of the inner frame 31. The indoor side wall portion 316 protrudes downward from the indoor side end portion of the extension portion 312. As shown in FIG. 3, the position of the lower end surface 316a of the indoor side wall portion 316 is arranged slightly above the position of the lower end surface 311b which is the lowest position in the face material accommodating portion 311.

[0015] As shown in FIGS. 6 and 7, a plurality of through holes 317 are provided in the extension portion 312 of the inner frame 31. The through holes 317 are formed in a long hole shape having a length extending over substantially the entire length in the prospective direction of the extension portion 312 as shown in FIG. 6, and are arranged at intervals in the length direction of the inner frame 31.

[0016] The outer frame 32 of the upper frame 3 is made of a plate material that constitutes the upper outer surface of the window frame 2. The length of the outer frame 32 in the left - right direction is slightly longer than the length of the inner frame 31 in the left - right direction. The length of the outer frame 32 in the prospective direction is longer than the length of the inner frame 31 in the prospective direction. The outer frame 32 extends in the prospective direction toward the outdoor side and the indoor side respectively more than the inner frame 31.

[0017] On the inner peripheral surface 32a of the outer frame 32, a plurality of protrusion portions 321 that linearly extend along the left - right direction which is the length direction of the outer frame 32 are provided. The plurality of protrusion portions 321 are arranged parallel to each other at regular intervals in the prospective direction.

[0018] On the outer peripheral surface 32b of the outer frame 32, a flange portion 322 protruding upward is provided. The position of the flange portion 322 along the prospective direction of the window frame 2 is substantially equal to the position of the outdoor-side surface of the facing material 6 along the prospective direction of the window frame 2. The flange portion 322 is an attachment site for attaching the upper frame 3 of the window frame 2 to the building body. As shown in FIG. 3, it is fixed to the outdoor-side body surface of the building by a fixing screw SC1 passing through the flange portion 322.

[0019] The outer frame 32 is arranged in parallel at a certain interval above the outer peripheral side of the inner frame 31. The upper end portion 314a of the outdoor-side wall portion 314, which is the uppermost protruding portion of the inner frame 31, is arranged at a distance below the inner peripheral surface 32a of the outer frame 32. The space between the inner frame 31 and the outer frame 32 forms the upper air flow path F1 of the window frame 2. [[ID=!]]

[0020] The outdoor-side end of the air flow path F1 is arranged on the outdoor-side finding surface of the window frame 2 and communicates with the outdoor side through an outdoor-side intake and exhaust port F1a that opens to the outdoor side. The outdoor-side intake and exhaust port F1a is formed in a horizontally long slit shape between the upper end portion 314a of the outdoor-side wall portion 314 of the inner frame 31 and the inner peripheral surface 32a of the outer frame 32. The indoor-side end of the air flow path F1 communicates with the indoor side through a plurality of through holes 317 provided in the extension portion 312 of the inner frame 31. The through holes 317 are arranged on the inner peripheral-side prospective surface of the upper frame 3 and open to the inside of the window frame 2 on the indoor side of the facing material 6. These through holes 317 constitute the indoor-side intake and exhaust port F1b of the air flow path F1.

[0021] On the extension portion 312 of the inner frame 31, a filter 318 is provided to cover all the indoor-side intake and exhaust ports F1b from the inside of the window frame 2. This prevents dust, pollen, insects, etc. from entering the indoor side through the air flow path F1. The lower end surface 316a of the indoor-side wall portion 316 protrudes below the filter 318. The filter 318 is detachable and can be cleaned and replaced. The filter 318 is omitted in FIGS. 6 and 7.

[0022] As shown in Figures 4, 6, and 7, the inner frame 51 of the left and right vertical frames 5 has a panel housing section 511 that cradles and accommodates the left and right side edges of the panel 6, and an extension section 512 that extends in the depth direction toward the interior from the panel housing section 511. The panel housing section 511 and the extension section 512 of the inner frame 51 are formed integrally. The left and right side edges of the panel 6 are housed in the panel housing section 511. The panel 6 is supported within the panel housing section 511 by a trim piece 513 positioned on the interior side.

[0023] The inner frame 51 has an exterior wall portion 514 that forms the exterior surface of the inner frame 51. The exterior wall portion 514 protrudes outward to the left and right from the interior end surface 511a of the panel housing portion 511. The position of the exterior wall portion 514 of the vertical frame 5 in the depth direction of the window frame 2 is equal to the position of the exterior wall portion 314 of the upper frame 3. A sealing material 515 made of rubber or the like is attached to the interior surface of the left and right outer ends 514a of the exterior wall portion 514, extending along the length of the inner frame 51.

[0024] The inner frame 51 has an interior wall portion 516 that forms the interior-facing surface of the inner frame 51. The interior wall portion 516 protrudes inward from the interior end of the extension portion 512. As shown in Figure 4, the position of the interior end surface 516a of the interior wall portion 516 is located slightly outward from the position of the inner end surface 511b, which is the innermost position in the surface material housing portion 511.

[0025] As shown in Figures 6 and 7, the extension 512 of the inner frame 51 is provided with a plurality of through holes 517. The through holes 517 are formed in the shape of elongated holes that have a length that extends approximately the entire length of the extension 512 in the depth direction, and are arranged at intervals along the length of the inner frame 51.

[0026] The outer frames 52 of the left and right vertical frames 5 are made of plate material that constitutes the left and right outer surfaces of the window frame 2. The vertical length of the outer frame 52 is slightly longer than the vertical length of the inner frame 51. The depth length of the outer frame 52 is longer than the depth length of the inner frame 51. The outer frame 52 extends in the depth direction toward the exterior and interior sides, respectively, compared to the inner frame 51.

[0027] The inner circumferential surface 52a of the outer frame 52 is provided with a plurality of projections 521 that extend linearly along the vertical direction, which is the length direction of the outer frame 52. The plurality of projections 521 are arranged parallel to each other at regular intervals in the depth direction.

[0028] The outer circumferential surface 52b of the outer frame 52 is provided with a flange portion 522 that protrudes outward. The position of the flange portion 522 along the depth direction of the window frame 2 is approximately equal to the position of the exterior surface of the facing material 6 along the depth direction of the window frame 2. The flange portion 522 is the mounting part for attaching the vertical frame 5 of the window frame 2 to the building structure, and as shown in Figure 4, it is fixed to the exterior surface of the building structure by fixing screws SC3 that pass through the flange portion 522.

[0029] The outer frame 52 is arranged parallel to the left and right outer sides of the inner frame 51, at regular intervals. The outer end portion 514a of the outdoor side wall portion 514, which is the part of the inner frame 51 that protrudes the furthest outward, is positioned further inward than the inner circumferential surface 52a of the outer frame 52. The space between the inner frame 51 and the outer frame 52 forms the air passage F2 on the left and right sides of the window frame 2.

[0030] The outdoor end of the air passage F2 communicates with the outside through an outdoor intake / exhaust port F2a, which is located on the outdoor surface of the window frame 2 and opens to the outside. The outdoor intake / exhaust port F2a is formed in the shape of a vertical slit between the outer end 514a of the outdoor wall portion 514 of the inner frame 51 and the inner circumferential surface 52a of the outer frame 52. The indoor end of the air passage F2 communicates with the indoor side through a plurality of through holes 517 provided in the extension portion 512 of the inner frame 51. The through holes 517 are located on the inner circumferential surface of the vertical frame 5 and open to the inside of the window frame 2 on the indoor side of the facing material 6. These through holes 517 constitute the indoor intake / exhaust port F2b of the air passage F2.

[0031] A filter 518 is provided on the extension 512 of the inner frame 51, covering all indoor intake and exhaust ports F2b from the inside. This prevents dust, pollen, insects, etc. from entering the room through the air passage F2. The inner end surface 516a of the indoor wall portion 516 protrudes inward from the filter 518. The filter 518 is removable and can be cleaned and replaced as needed. The filter 518 is omitted in Figures 6 and 7.

[0032] The lower frame 4 of the window frame 2 does not have an inner frame or air passage, and independently constitutes the lower outer surface of the window frame 2. The length of the lower frame 4 in the left-right direction is equal to the length of the outer frame 32 of the upper frame 3 in the left-right direction. The length of the lower frame 4 in the depth direction is equal to the length of the outer frames 32, 52 of the upper frame 3 and the left and right vertical frames 5 in the depth direction.

[0033] As shown in Figures 3, 5, and 6, the lower frame 4 has a panel housing section 41 that cradles and accommodates the lower edge of the panel 6. The lower edge of the panel 6 is housed in the panel housing section 41. The panel 6 is supported within the panel housing section 41 by a trim piece 42 positioned on the interior side. The lower frame 4 extends from the panel housing section 41 toward the exterior and interior sides in the depth direction, respectively.

[0034] The exterior wall portion 43 that forms the exterior surface of the lower frame 4 is positioned to face the exterior. The position of the exterior wall portion 43 along the depth direction of the window frame 2 is equal to the position of the exterior wall portions 314 and 514 of the upper frame 3 and vertical frame 5 along the depth direction of the window frame 2.

[0035] The inner circumferential surface 4a of the lower frame 4 is provided with a plurality of protrusions 44 that extend linearly along the left-right direction, which is the length direction of the lower frame 4. The plurality of protrusions 44 are arranged parallel to each other at regular intervals in the depth direction.

[0036] The outer circumferential surface 4b of the lower frame 4 is provided with a flange portion 45 that protrudes downward. The position of the flange portion 45 along the depth direction of the window frame 2 is approximately equal to the position of the exterior surface of the facing material 6 along the depth direction of the window frame 2. The flange portion 45 is the mounting part for attaching the lower frame 4 of the window frame 2 to the building structure, and as shown in Figure 3, it is fixed to the exterior surface of the building structure by fixing screws SC2 that pass through the flange portion 45.

[0037] The upper frame 3, lower frame 4, and left and right vertical frames 5 are each cut at a 45° angle along their length. The upper frame 3, lower frame 4, and left and right vertical frames 5 are framed into a rectangle by butting the ends of adjacent frames together. Specifically, the ends of the outer frame 32 of the upper frame 3, the outer frame 52 of the lower frame 4, and the left and right vertical frames 5 are connected, and the ends of the inner frame 31 of the upper frame 3 and the inner frames 51 of the left and right vertical frames 5 are also connected. The inner frames 31 and 51, which form a gate shape through the connection, are fixed to the inner circumferential surface 4a of the lower frame 4 at the lower ends of the left and right inner frames 51. As a result, the air passage F1 of the upper frame 3 and the air passage F2 of the left and right vertical frames 5 communicate in the circumferential direction of the window frame 2, and the outdoor intake and exhaust port F1a of the upper frame 3 and the outdoor intake and exhaust port F2a of the left and right vertical frames 5 communicate in the circumferential direction of the window frame 2. The projections 321 on the outer frame 32 of the upper frame 3, the projections 521 on the outer frames 52 of the left and right vertical frames 5, and the projections 44 on the lower frame 4 are all continuous in the circumferential direction of the window frame 2.

[0038] The frame 7 is attached to the interior end of the window frame 2. The frame 7 is formed by framing an upper frame member 71, a lower frame member 72, and left and right vertical frame members 73, each made of hollow rectangular material, into a rectangular frame. The upper frame member 71 is spaced interiorly away from the inner frame 31 of the upper frame 3 and is attached to the interior end of the inner circumferential surface 32a of the outer frame 32. The lower frame member 72 is attached to the interior end of the inner circumferential surface 4a of the lower frame 4. The left and right vertical frame members 73 are spaced interiorly away from the inner frame 51 of the vertical frame 5 and are attached to the interior end of the inner circumferential surface 52a of the outer frame 52.

[0039] The lower surface 71a of the upper frame member 71 is positioned slightly above the lower end surface 311b of the panel material housing section 311. The upper surface 72a of the lower frame member 72 is positioned slightly below the upper end surface 41a of the panel material housing section 41. The inner surface 73a of the vertical frame member 73 is positioned slightly outward from the inner end surface 511b of the panel material housing section 511.

[0040] On the interior side of the lower surface 71a of the upper frame member 71, the upper surface 72a of the lower frame member 72, and the interior surfaces 73a of the left and right vertical frame members 73, flange portions 711, 721, and 731 are integrally provided via stepped portions 71b, 72b, and 73b that protrude inward. The flange portions 711, 721, and 731 protrude toward the interior side of the frame 7.

[0041] The opening / closing member 8 is a member that moves along the depth direction of the window frame 2 to simultaneously open and close air passages F1 and F2 that extend along three sides of the window frame 2. As shown in Figures 8 and 9, the opening / closing member 8 of this embodiment consists of a rectangular movable frame that extends around all four sides of the window frame 2 and is positioned on the inner circumference side of the window frame 2 and on the interior side of the facing material 6. The opening / closing member 8 is composed of an inner circumference side plate portion 81, outer circumference side plate portions 82 provided on the upper surface and left and right outer surfaces of the inner circumference side plate portion 81, and a corner frame portion 83 provided on the lower surface of the inner circumference side plate portion 81. The opening / closing member 8 can be integrally molded, for example, by injection molding using a resin material.

[0042] The inner circumferential plate portion 81 of the opening / closing member 8 is constructed in a rectangular tubular shape by an upper inner circumferential plate 811, a lower inner circumferential plate 812, and left and right vertical inner circumferential plates 813. The opening area on the inner circumferential side of the inner circumferential plate portion 81 is the same as the opening area of ​​the facing material 6 (the area through which light passes through the facing material 6) which is formed in a rectangular shape by the lower end surface 311b of the facing material housing portion 311 of the upper frame 3, the upper end surface 41a of the facing material housing portion 41 of the lower frame 4, and the inner end surface 511a of the facing material housing portion 511 of the vertical frame 5.

[0043] As shown in Figures 3 and 4, the inner perimeter side plate portion 81 is positioned on the interior side of the facing material 6 and on the inner perimeter side of the frame 7. The inner perimeter side plate portion 81 extends along the depth direction from the facing material 6 to the frame 7. The inner perimeter side plate portion 81 and the flange portions 711, 721, and 731 of the frame 7 form the same surface along the depth direction.

[0044] The upper inner perimeter side plate 811 is positioned below the extension portion 312 of the inner frame 31 in the upper frame 3. The outer end of the upper inner perimeter side plate 811 is provided with an opening position regulating projection 811a that protrudes upward. The opening position regulating projection 811a is positioned below the filter 318 provided on the extension portion 312 and sandwiched between the indoor side wall portion 316 of the inner frame 31 and the facing material 6. As shown in Figure 3, when the opening / closing member 8 is moved to its outermost position, the opening position regulating projection 811a is close to the indoor surface of the facing material 6. The upper inner perimeter side plate 811 covers the entire extension portion 312 of the inner frame 31 from below. The indoor end of the upper inner perimeter side plate 811 is positioned to overlap the lower surface 71a of the upper frame member 71.

The protrusions 84 extend linearly along the depth direction, which is the direction of movement of the opening / closing member 8. The multiple protrusions 84 are arranged parallel to each other at regular intervals in the circumferential direction of the opening / closing member 8. The multiple protrusions 84 of the opening / closing member 8 are in contact with the multiple protrusions 321, 44, and 521 provided on the upper frame 3, lower frame 4, and left and right vertical frames 5, respectively.

[0053] Next, the ventilation operation of the fixed window 1 will be explained with reference to Figures 3 to 5, 10 and 11. Figures 3 to 5 show the state in which the opening / closing member 8 is moved to its outermost position. At this time, the flow path closing projection 821a of the upper outer peripheral side plate 821 of the opening / closing member 8 abuts against the sealing material 315 of the inner frame 31 of the upper frame 3, and the flow path closing projection 823a of the vertical outer peripheral side plate 823 of the opening / closing member 8 abuts against the sealing material 515 of the inner frame 51 of the left and right vertical frames 5. The upper inner peripheral side plate 811 and the vertical inner peripheral side plate 813 of the inner peripheral side plate portion 81 of the opening / closing member 8 cover the extensions 312 and 512. This restricts the closed position of the opening / closing member 8. At this time, the flow path closing projection 821a of the upper outer peripheral side plate 821 abuts against the sealing material 315, closing the outdoor intake / exhaust port F1a of the air passage F1 of the upper frame 3. The flow path closing protrusion 823a of the vertical outer peripheral plate 823 comes into contact with the sealing material 515, thereby closing the outdoor intake and exhaust ports F2a of the air passage F2 of the left and right vertical frames 5. As a result, the airflow in the indoor-outdoor direction through the FIX window 1 is blocked.

[0054] From this state, when the operator places their hand on the handle recess 814 of the opening / closing member 8 from the indoor side and moves the opening / closing member 8 towards the indoor side, as shown in Figures 10 and 11, the flow path closing protrusions 821a and 823a of the opening / closing member 8 move away from the sealing material 315 and 515 towards the indoor side, opening the outdoor intake / exhaust port F1a of the air passage F1 of the upper frame 3 and the outdoor intake / exhaust port F2a of the air passages F2 of the left and right vertical frames 5, respectively. At the same time, the inner peripheral plate portion 81 of the opening / closing member 8 moves away from the surface material 6 towards the indoor side, opening the indoor intake / exhaust port F1b of the air passage F1 of the upper frame 3 and the indoor intake / exhaust port F2b of the air passages F2 of the left and right vertical frames 5, respectively. As a result, the FIX window 1 can ventilate between the outdoor and indoor sides via the air passages F1 and F2, enabling ventilation.

[0055] The extension direction of the projection 84 provided on the opening / closing member 8 and the extension direction of the projections 321, 44, and 521 provided on the upper frame 3 and the left and right vertical frames 5 intersect with each other. Since the projections 84 and 321, 44, and 521 that come into contact with each other are close to point contact, the contact area between the opening / closing member 8 and the upper frame 3, lower frame 4, and left and right vertical frames 5 is reduced. As a result, the sliding resistance when the opening / closing member 8 moves is reduced, and the opening / closing member 8 can be moved more easily.

[0056] As shown in Figures 10 and 11, when the opening / closing member 8 is moved to its furthest point toward the interior, the opening position restricting protrusions 811a and 813a of the upper inner perimeter side plate 811 and the vertical inner perimeter side plate 813 of the opening / closing member 8 come into contact with the interior wall portions 316 and 516 of the inner frames 31 and 51 of the upper frame 3 and the left and right vertical frames 5 from the exterior. This restricts the maximum opening position of the opening / closing member 8. At this time, the interior intake and exhaust vents F1b and F2b are opened to their widest extent, allowing the FIX window 1 to provide maximum ventilation. The interior ends of the upper inner perimeter side plate 811, the lower inner perimeter side plate 812, and the left and right vertical inner perimeter side plates 813 of the inner perimeter side plate portion 81 of the opening / closing member 8 slide along the interior surface of the frame 7 and come into contact with the stepped portions 71b, 72b, and 73b from the exterior.

[0057] The opening / closing member 8 may be configured such that when it moves to its outermost position, the inner circumferential plate portion 81 closes the indoor intake / exhaust ports F1b and F2b of the air passages F1 and F2. In this case, for example, the space between the open position regulating protrusions 811a and 813a of the inner circumferential plate portion 81 and the inner frames 31 and 51, or the space between the open position regulating protrusions 811a and 813a of the inner circumferential plate portion 81 and the retaining trim 313 and 513 can be sealed with a sealing material. The opening / closing member 8 may also be configured such that both the outer circumferential plate portion 82 and the inner circumferential plate portion 81 simultaneously close both the outdoor intake / exhaust ports F1a and F2a and the indoor intake / exhaust ports F1b and F2b of the air passages F1 and F2.

[0058] The fixed window 1, which is a building component according to this embodiment, provides the following effects.

[0059] (1) The fixed window 1 is provided around the four sides of the opening of the building and comprises a window frame 2 which is framed by an upper frame 3, a lower frame 4 and left and right vertical frames 5, a facing material 6 which is fitted inside the window frame 2, air passages F1 and F2 which are provided on three of the four sides of the window frame 2 and connect outdoor intake and exhaust ports F1a and F2a which open to the outside and indoor intake and exhaust ports F1b and F2b which open to the inside, and an opening and closing member 8 which is provided inside the window frame 2 and opens and closes the air passages F1 and F2 by moving in the depth direction.

[0060] According to this, by simply moving the opening / closing member 8 in the depth direction from the indoor side, the air passages F1 and F2 can be opened and closed, allowing for timely and easy switching between ventilation and non-ventilation. By adjusting the position of the opening / closing member 8 in the depth direction, the size of the air passages F1 and F2 can be adjusted, allowing for arbitrary adjustment of the degree of ventilation. Since the opening / closing member 8 moves in the depth direction, the opening area of ​​the panel 6 does not narrow as a result of the opening / closing operation.

[0061] (2) In the fixed window 1 described in (1) above, the sides of the window frame 2 having air passages F1 and F2 are composed of inner frames 31 and 51 that house the edges of the facing material 6, and outer frames 32 and 52 that are spaced apart on the outer periphery side of the inner frames 31 and 51, and the air passages F1 and F2 are formed by the space between the inner frames 31 and 51 and the outer frames 32 and 52, and the opening / closing member 8 has an inner periphery side plate portion 81 that is positioned on the inner periphery side of the inner frames 31 and 51 and extends in the depth direction, and an outer periphery side plate portion 82 that is positioned between the inner frames 31 and 51 and the outer frames 32 and 52 and extends in the depth direction, and when the opening / closing member 8 is moved to the outermost position, either or both of the inner periphery side plate portion 81 and the outer periphery side plate portion 82 close the air passages F1 and F2.

[0062] According to this, by simply moving the opening / closing member 8 toward the outside, the air passages F1 and F2 can be easily closed by either or both of the inner circumferential plate portion 81 and the outer circumferential plate portion 82.

[0063] (3) In the fixed window 1 described in (1) or (2) above, the opening / closing member 8 and the window frame 2 are provided with a plurality of protrusions 84, 321, 44, 521 that reduce the area in contact with each other.

[0064] According to this, the contact area between the opening / closing member 8 and the window frame 2 is reduced, which reduces the sliding resistance when the opening / closing member 8 moves, allowing the opening / closing member 8 to move more easily.

[0065] (4) In the fixed window 1 described in any one of (1) to (3) above, removable filters 318 and 518 are provided at the indoor intake and exhaust ports F1b and F2b.

[0066] According to this design, dust, pollen, insects, etc., can be prevented from entering the room through air passages F1 and F2. Filters 318 and 518 are removable and can be taken out for cleaning and replacement.

[0067] Although one embodiment of the building fittings of this disclosure has been described above, the building fittings of this disclosure are not limited thereto. For example, in this embodiment, air passages F1 and F2 are formed in the upper frame 3 and the left and right vertical frames 5, but the air passages only need to be provided on at least one side of the perimeter of the window frame 2. However, it is desirable not to provide air passages on at least one side of the perimeter of the window frame 2 from the viewpoint of increasing the wind pressure resistance of the window frame 2.

[0068] The air passage is not limited to being provided along the entire length of one side of the window frame 2. The air passage only needs to be provided along at least a portion of the length of one side of the window frame 2.

[0069] In this embodiment, multiple protrusions 321, 44, and 521 are provided on the upper frame 3 and left and right vertical frames 5 of the window frame 2, and multiple protrusions 84 are provided on the opening / closing member 8, but the embodiment is not limited to this. The protrusions may be provided on at least one of the window frame 2 and the opening / closing member 8. If the protrusions are provided on only one of the window frame 2 and the opening / closing member 8, the protrusions are not limited to linear protrusions, but may be point-shaped protrusions such as hemispherical ones.
