An embodiment of this disclosure will be described in detail below with reference to the drawings. In this specification, "face direction" refers to the surface direction of the sash 12 of the window sash 1 installed in the opening 100a of the building frame 100, or the surface direction of the screen 23 pulled out from the storage frame 21 of the screen device 2. "depth direction" refers to the thickness direction of the sash 12 or the thickness direction of the screen 23 pulled out from the storage frame 21 of the screen device 2. In the face direction, the left and right directions are referred to as the left-right direction. "Face surface" refers to the respective surfaces of the window sash 1 or screen device 2 facing the exterior and interior sides, respectively, while "depth surface" refers to the surface of the window sash 1 or screen device 2 extending in the interior-exterior direction. In the drawings, the exterior side is described as "exterior side X1," and the interior side is described as "interior side X2."

The mounting structure of the screen device 2 (outdoor fixture) of the first embodiment will now be described. As shown in Figures 1 to 3, the screen device 2 is attached to the outdoor side X1 of the window sash 1 (fixture) which is installed in the opening 100a of the building frame 100. In this embodiment, the screen device 2 is a type of screen device in which the screen 23 is pulled out downwards from a storage frame 21 located at the top. As shown in Figures 3 and 4, the screen device 2 is attached to the outdoor side X1 of the sash frame 11 of the window sash 1 by a screen device mounting bracket 4 (outdoor fixture mounting bracket). The screen device mounting bracket 4 fixes the screen device 2 to the outdoor side X1 of the sash frame 11.

The window sash 1 will now be described. The window sash 1 is installed in the opening 100a of the building frame 100 and, as shown in Figures 1 to 3, comprises a rectangular sash frame 11 and two sashes 12, 12. The sash frame 11 is installed in the opening 100a of the building frame 100 and has an upper frame 111, a lower frame 112, and a pair of vertical frames 113, 113 (sash frame), which are assembled in a rectangular shape. The sashes 12, 12 are constructed as sliding windows that can slide horizontally within the sash frame 11, allowing the opening of the sash frame 11 to be opened and closed.

As shown in Figure 3, each pair of vertical frames 113, 113 has a vertical frame body 114 and a vertical frame projection 115. The vertical frame body 114 is positioned outside the left and right ends of the shoji screen 12 and extends in the depth direction. The vertical frame projection 115 extends and protrudes from the outdoor side X1 end of the vertical frame body 114 toward the outdoor side X1. As will be described in detail later, the screen device 2 is fixed to the vertical frame projection 115 via a screen device mounting bracket 4.

The screen device 2 will now be described. As shown in Figures 1 to 3, the screen device 2 is positioned on the outdoor side X1 of the sash frame 11 of the window sash 1. The screen device 2 comprises a storage frame 21 (screen storage section), a winding shaft section 22 (see Figure 2) housed in the storage frame 21, a screen 23 that can be wound onto the winding shaft section 22 and pulled out downward from the winding shaft section 22, a movable frame 24 (movable member) fixed to the lower end of the screen 23, a pair of guide rails 3, 3 (guide sections) on the left and right, and an outdoor side cleaning member 711 (first cleaning member) provided in the unwinding opening 21a formed on the lower surface of the storage frame 21.

As shown in Figures 3 to 5, the storage frame 21 of the screen device 2 is attached to the pair of vertical frames 113, 113 of the window sash frame 11 of the window sash 1 via the screen device mounting bracket 4 by screwing screws 43 inward from the front of the exterior side X1. The screws 43 are screwed inward from the front of the exterior side X1. This allows the screen device mounting bracket 4 to be easily fixed to the sash frame 11 even when either the left or right, or both, of the opening is an inside corner where it is difficult to secure working space. Details of the mounting structure of the screen device 2 will be described later.

As shown in Figure 2, the storage frame 21 is provided on the exterior side X1 of the upper part of the opening 100a of the building structure 100, and is positioned on the upper part of the exterior side X1 of the upper frame 111 of the sash frame 11. The back surface (interior side X2) of the storage frame 21 is positioned in contact with the exterior wall surface 101a of the exterior side X1 of the upper part of the opening 100a of the building structure 100. The storage frame 21 is positioned in contact with the exterior wall surface 101a of the exterior side X1 of the building structure 100 at the upper part of the periphery of the opening 100a of the building structure 100, and is attached by being fixed to the pair of vertical frames 113, 113 of the sash frame 11 of the window sash 1 via mounting brackets 5 and screen device mounting brackets 4.

As shown in Figures 1 and 2, the storage frame 21 is formed in a box shape extending in the left-right direction. As shown in Figure 1, the storage frame 21 comprises a storage frame body 211 and a pair of end cap members 212 attached to both ends of the storage frame body 211 in the left-right direction. As shown in Figure 2, a screen feed opening 21a (screen feed section) is formed on the lower surface of the storage frame 21, opening downwards and extending in the left-right direction.

The storage frame 21 is connected to the screen device mounting bracket 4 via mounting brackets 5. As shown in Figures 2 and 4, the mounting brackets 5 are positioned at both ends of the screen device mounting bracket 4 in the left-right direction, connecting the storage frame 21 and the screen device mounting bracket 4 at both ends in the left-right direction. The mounting brackets 5 are formed in an L-shape with the lower side of the outdoor side X1 open. As shown in Figure 2, the mounting brackets 5 have a vertically extending portion 51, an outdoor extension plate 52 that bends and extends from the upper end of the vertically extending portion 51 toward the outdoor side X1, and a protruding plate 53 that protrudes upward by a predetermined width from the left-right outer end of the outdoor extension plate 52.

The vertically extending portion 51 is fixed to the first fixing member 41 (described later) of the screen device mounting bracket 4 by screws 51a (fastening members), as shown in Figure 6. The protruding plate 53 is fixed to the mounting plate 213 located on the left-right end side of the storage frame 21 of the screen device mounting bracket 4 by screws 53a (fastening members).

The storage frame 21 has a storage frame position adjustment mechanism 6 (position adjustment mechanism) that allows adjustment of its mounting position in the depth direction according to the depth direction positions Xa, Xb, and Xc of the exterior wall surfaces 101a, 101b, and 101c (see Figures 8 to 10) of the exterior side X1 of the building frame 100. Details of the storage frame position adjustment mechanism 6 will be described later.

As shown in Figure 2, the winding shaft 22 is housed inside the storage frame 21. The storage frame 21 allows the screen 23 to be wound onto and unwound by winding the screen 23 onto and from the winding shaft 22.

The winding shaft portion 22 is positioned inside the storage frame 21 on the upper side of the opening 100a of the building frame 100. The winding shaft portion 22 extends in the left-right direction and is configured to rotate around a central axis extending in the left-right direction. The base end of the screen 23 is fixed to the winding shaft portion 22, and the winding shaft portion 22 is configured to wind up the screen 23. The winding shaft portion 22 is biased to rotate the screen 23 in the winding direction by a biasing member (not shown) that biases the screen 23 in the winding direction. For example, a spring-type coil spring can be used as the biasing member.

The screen 23 is formed in a sheet shape, for example, from a mesh-like material made of resin. The screen 23 is pulled out downwards from an opening 21a formed on the lower surface of the storage frame 21. The base end of the screen 23 is fixed to the winding shaft 22, and it is wound onto the winding shaft 22 and pulled out from the winding shaft 22. This allows the screen 23 to be pulled out from the storage frame 21 and retracted into the storage frame 21 for storage.

Conventionally, when a sliding screen door is installed on the exterior side of a window sash, the screen door is attached to the window frame, which obstructs solar heat gain and allows insects to enter the room through the gap between the screen door and the sash. In contrast, in this embodiment, a screen device 2, in which the screen 23 is constructed as a sheet of mesh, is placed on the exterior side X1 of the window sash 1. As a result, when the screen 23 is fully opened, the screen 23 can be stored in the storage frame 21, thereby improving solar heat gain, ventilation performance, and view performance. Furthermore, when the screen 23 is fully closed, the mesh of the screen 23 covers the front of the window sash 1 from the exterior side X1, improving insect-proof performance. In addition, by covering the front of the window sash 1 from the exterior side X1 with the mesh of the screen 23, solar heat shielding performance can be improved, thermal insulation performance can be improved, and ultraviolet rays can be cut. In particular, in this embodiment, by arranging the screen device 2, in which the screen 23 is constructed in a sheet-like form using a mesh, on the exterior side X1 of the window sash 1, the solar radiation shading performance can be improved compared to when the screen device is arranged on the interior side X2 of the window sash 1.

As shown in Figure 5, a pair of edge members 231, 231 (locking parts) are provided at both ends of the screen 23 in the left-right direction (direction perpendicular to the extension direction). The pair of edge members 231 provided at both ends of the screen 23 in the left-right direction are slidably positioned vertically while locked into the guide grooves 32a of the internal rail 32, which is located inside the pair of left and right guide rails 3, 3. As a result, the pair of edge members 231, 231 are guided by the pair of guide rails 3, 3 while being locked to them.

As shown in Figure 2, an edge member 232 is attached to the base end of the screen 23. The edge member 232 attached to the base end of the screen 23 is locked into the mounting groove 221 of the winding shaft 22. An edge member 233 is attached to the lower end of the screen 23. The edge member 233 attached to the lower end of the screen 23 is locked into the mounting groove 242a of the movable frame 24.

As shown in Figures 1 and 2, the movable frame 24 is fixed to the lower end of the screen 23, and is positioned at the leading edge in the screen 23's extension direction. The movable frame 24 also functions as a gripping part, held by the user when opening and closing the screen 23.

The movable frame 24 is configured to move vertically between an open position where the screen 23 opens the screen opening 2a and a closed position where the screen 23 closes the screen opening 2a. When the movable frame 24 is in the closed position where the screen 23 closes the screen opening 2a, it is positioned opposite the visible surface X1 on the outdoor side of the lower frame 112. The movable frame 24 is biased toward the storage frame 21 by a biasing member (not shown) that biases the screen 23 in the winding direction.

As shown in Figure 7, the movable frame 24 has an outer frame portion 241, a screen end holding portion 242, and a pair of side cover portions 243 (see Figure 4).

The outer frame portion 241 is formed in a frame shape that extends in the left-right direction and opens upward. A mounting groove 241a (mounting groove) for attaching a mohair member 25 (closing member) is formed on the indoor side X2 visible surface of the lower end of the outer frame portion 241. The mounting groove 241a is formed in a groove shape that recesses from the indoor side X2 surface of the lower end of the outer frame portion 241 toward the outdoor side X1, and extends in the left-right direction.

As shown in Figure 7, a mohair member 25 (a sealing member) is attached to the sealing member mounting groove 241a formed on the indoor side X2 surface of the movable frame 24. The mohair member 25 protrudes from the indoor side X2 surface of the lower end of the outer frame portion 241 and extends in the left-right direction. The mohair member 25 has a mounting plate 251 attached to the sealing member mounting groove 241a, and a mohair portion 252 that protrudes from the mounting plate 251 to the indoor side X2.

When the screen 23 is extended and in the closed position, and the movable frame 24 is positioned on the outdoor side X1 of the lower frame 112, the mohair member 25 protrudes from the indoor side X2 of the movable frame 24 toward the visible surface of the lower frame 112, and the tip of the indoor side X2 of the mohair member 25 is positioned in contact with or close to the visible surface 1121 of the outdoor side X1 of the lower frame 112. The tip of the indoor side X2 of the mohair member 25 may be positioned in contact with the visible surface 1121 of the outdoor side X1 of the lower frame 112, or it may be positioned close enough to the visible surface 1121 of the outdoor side X1 of the lower frame 112 without contacting it, to the extent that insects cannot enter the visible surface 1121 of the outdoor side X1 of the lower frame 112.

The screen end retaining portion 242 is positioned in the portion of the outer frame 241 that is open upwards. The screen end retaining portion 242 holds the edge member 233 attached to the lower end of the screen 23. The screen end retaining portion 242 has a connecting portion 242b that extends vertically with its upper end open, and a mounting groove 242a formed at the lower end of the connecting portion 242b. With the lower end of the screen 23 passing through the connecting portion 242b, the edge member 233 attached to the lower end of the screen 23 is locked into the mounting groove 242a of the screen end retaining portion 242.

As shown in Figure 1, the pair of guide rails 3, 3 are provided at both ends in a direction perpendicular to the screen 23's extension direction and extend in the screen 23's extension direction. Specifically, the pair of guide rails 3, 3 are formed extending vertically at both ends in the left-right direction on the exterior side X1 of the window sash 1. The pair of guide rails 3, 3 are positioned on the outer periphery of the sash frame 11's opening in the left-right direction and extend vertically on the outer periphery of the sash frame 11's opening.

The pair of guide rails 3, 3 guide both ends of the screen 23 in a direction perpendicular to the screen's extension direction. The pair of guide rails 3, 3 support both ends of the movable frame 24 in the left-right direction so that they can slide vertically, and also guide both ends of the screen 23 in the left-right direction so that they can slide vertically when the screen 23 moves vertically.

Next, the outdoor cleaning member 711 provided in the extension opening 21a formed on the lower surface of the storage frame 21 will be described. As shown in Figure 8, the outdoor cleaning member 711 (first cleaning member) is provided in the extension opening 21a formed on the lower surface of the storage frame 21. The outdoor cleaning member 711 is positioned on the outdoor side X1 of the screen 23 at the extension opening 21a of the storage frame 21. The outdoor cleaning member 711 is made of, for example, mohair. The tip of the outdoor cleaning member 711 is positioned to abut against the outdoor side X1 surface of the screen 23 when the screen 23 is pulled out or retracted. The outdoor cleaning member 711 is attached to the storage frame 21 via the mounting bracket 5 while being held by the cleaning member holding part 712.

The cleaning member holder portion 712 is formed extending in the left-right direction. The cleaning member holder portion 712 is positioned on the inside of the storage frame 21, above the dispensing opening 21a, so as to close the dispensing opening 21a formed on the lower surface of the storage frame 21.

The cleaning member holding section 712 includes a depth-extending plate 7121 extending in the depth direction above the dispensing opening 21a formed on the lower surface of the storage frame 21, an outdoor downward projection 7122 projecting downward from the outdoor end X1 of the depth-extending plate 7121, an indoor downward projection 7123 projecting downward from the indoor end X2 of the depth-extending plate 7121, and a cleaning member mounting groove 7124 (holding groove) positioned on the indoor surface X2 of the indoor downward projection 7123.

The length of the extension plate 7121 in the depth direction is such that the sum of the length of the extension plate 7121 of the cleaning member holding part 712 and the length of the outdoor cleaning member 711 in the depth direction is such that even if the position of the storage frame 21 changes in the depth direction due to the storage frame position adjustment mechanism 6 (position adjustment mechanism) of the storage frame 21 (described later), the extension plate 7121 and the outdoor cleaning member 711 can still close the opening 21a formed on the lower surface of the storage frame 21, in the portion X1 on the outdoor side of the screen 23 at the opening 21a of the storage frame 21. The extension plate 7121 in the depth direction is fixed to the outdoor extension plate 52 of the mounting bracket 5 by screws 712a (fastening members). Because the extension plate 7121 and the outdoor cleaning member 711 block the portion of the dispensing opening 21a formed on the lower surface of the storage frame 21 that is on the outdoor side X1 beyond the screen 23, insects can be prevented from entering the storage frame 21.

The cleaning member mounting groove 7124 is formed in a C-shape in cross-section, opening towards the indoor side X2, and extends horizontally across the entire longitudinal area of the cleaning member holding portion 712. The cleaning member mounting groove 7124 holds the outdoor cleaning member 711. The outdoor cleaning member 711 is detachably attached to the cleaning member mounting groove 7124.

The outdoor cleaning member 711 has a mounting plate 7111 attached to the cleaning member mounting groove 7124, and a cleaning portion 7112 protruding from the mounting plate 7111 toward the indoor side X2. The cleaning portion 7112 is, for example, mohair. The outdoor cleaning member 711 is detachable from the cleaning member holding portion 712 by sliding the mounting plate 7111 in the left-right direction along the cleaning member mounting groove 7124.

The cleaning member holder 712 is fixed to the mounting bracket 5 by screws 712a. When fixing the cleaning member holder 712 to the mounting bracket 5, the strength of contact between the outdoor cleaning member 711, held by the cleaning member holder 712, and the outdoor surface X1 of the screen 23 can be adjusted by adjusting the fixing position of the cleaning member holder 712 in the forward direction. In this embodiment, the cleaning member holder 712 is fixed to the storage frame 21 via the mounting bracket 5, but this is not limiting. For example, the cleaning member holder 712 may be fixed directly to the storage frame 21, or it may be fixed to the storage frame 21 via another component.

Next, the storage frame position adjustment mechanism 6 (position adjustment mechanism) of the storage frame 21 will be described. As shown in Figures 2 and 8, the storage frame position adjustment mechanism 6 can adjust the mounting position of the storage frame 21 in the depth direction according to the depth direction position of the exterior wall surface 101a of the exterior side X1 of the building frame 100.

Here, as shown in Figures 8 to 10, the positions in the depth direction of the exterior wall surfaces 101a, 101b, and 101c of the exterior wall material 102a, 102b, and 102c are different in thickness T1, T2, and T3 (T3 < T1 < T2), as shown in Figure 2, the distance from the fixing position Xk (see Figure 2) in the depth direction where the upper frame 111 of the sash frame 11 is fixed by the screw 111a is different in each case, as shown in Figures 8 to 10 (for example, position Xa (see Figure 8), position Xb (see Figure 9), and position Xc (see Figure 10) (positions Xc, position Xa, and position Xb in order from the interior side X2 to the exterior side X1)). As shown in Figures 8 and 9, the exterior wall materials 102a and 102b each consist of exterior wall material bodies 102a1 and 102b1, and spacer materials 102a2 and 102b2.

As shown in Figure 2, the upper frame 111 of the sash frame 11 is fixed to the beam member 103 of the building structure 100 at a fixed position Xk in the depth direction by screws 111a at the upper part of the periphery of the opening 100a of the building structure 100.

In this embodiment, the upper frame 111 of the sash frame 11 is fixed at the same fixed position Xk relative to the beam member 103 of the building structure 100, even when the thicknesses T1, T2, T3 (T3 < T1 < T2) of the exterior wall materials 102a, 102b, and 102c are different, as shown in Figures 8 to 10. Therefore, the position of the upper frame 111 in the depth direction is the same.

Conventionally, when attaching the screen device 2 to the sash frame 11, if the thicknesses T1, T2, and T3 of the exterior wall materials 102a, 102b, and 102c were different, the distance from the storage frame 21 of the screen device 2 to the exterior wall surfaces 101a, 101b, and 101c of the exterior side X1 of the building structure 100 was different. Therefore, it was difficult to position the storage frame 21 in contact with the exterior wall surfaces 101a, 101b, and 101c of the exterior side X1 of the building structure 100.

In contrast, in this embodiment, the storage frame position adjustment mechanism 6 can adjust the mounting position of the storage frame 21 in the depth direction according to the depth direction positions Xa, Xb, and Xc of the exterior wall surfaces 101a, 101b, and 101c of the exterior side X1 of the building frame 100. As shown in Figures 6 and 8, the storage frame position adjustment mechanism 6 comprises a protruding plate 53 of the mounting bracket 5, two screws 53a fixed to the protruding plate 53 of the mounting bracket 5, and guide grooves 2131 provided on a pair of mounting plates 213 (see Figure 6) located inside the cover members at the left and right ends of the storage frame 21.

As shown in Figures 6 and 8, the guide groove 2131 is formed as an elongated hole that penetrates the mounting plate 213 of the storage frame 21 in the left-right direction and extends for a predetermined length in the depth direction. As shown in Figures 8 to 10, the shaft of the screw 53a is inserted into the guide groove 2131, allowing the guide groove 2131 to move in the depth direction along the shaft of the screw 53a when the storage frame 21 is moved in the depth direction.

Therefore, even when the positions Xa, Xb, and Xc of the exterior wall surfaces 101a, 101b, and 101c of the exterior wall surface X1 of the building frame 100 are different in the depth direction, the guide groove 2131 can be moved in the depth direction along the shaft of the screw 53a by moving the storage frame 21 in the depth direction according to the positions Xa, Xb, and Xc of the exterior wall surfaces 101a, 101b, and 101c of the exterior wall surface X1 of the building frame 100 in the depth direction.

By moving the storage frame 21 in the forward direction, the guide groove 2131 is moved in the forward direction along the shaft of the screw 53a, so that the indoor side X2 of the storage frame 21 is positioned to contact the exterior wall surfaces 101a, 101b, and 101c of the outdoor side X1 of the building frame 100. Then, with the indoor side X2 of the storage frame 21 positioned to contact the exterior wall surfaces 101a, 101b, and 101c of the outdoor side X1 of the building frame 100, the mounting plate 213 and the protruding plate 53 of the mounting bracket 5 are fastened together and fixed using the screw 53a located in the guide groove 2131. This allows the storage frame 21 to be fixed to the upper frame 111 of the sash frame 11 via the mounting bracket 5, with the interior side X2 of the storage frame 21 in contact with the exterior wall surfaces 101a, 101b, and 101c of the exterior side X1 of the building structure 100. After being fixed with screws 53a, end cap members 212 are attached to the left and right ends of the storage frame 21, as shown in Figure 6, to conceal the screws 53a.

In this way, as shown in Figures 8 to 10, even when the thicknesses T1, T2, T3 (T3 < T1 < T2) of the exterior wall materials 102a, 102b, and 102c differ, resulting in different positions Xa, Xb, and Xc in the depth direction of the exterior wall surfaces 101a, 101b, and 101c of the exterior wall X1 of the building frame 100, the storage frame 21 can be positioned in contact with the exterior wall surfaces 101a, 101b, and 101c of the exterior wall X1 of the building frame 100 by adjusting the depth direction of the storage frame 21 and fastening the mounting plate 213 and the protruding plate 53 of the mounting bracket 5 together with the screws 53a located in the guide groove 2131.

Here, the cleaning member holding portion 712, which holds the outdoor cleaning member 711, is fixed to the outdoor extension plate 52 of the mounting bracket 5, and the mounting bracket 5 is fixed to the vertical frame 113 of the sash frame 11 via the screen device mounting bracket 4. Therefore, when the position of the storage frame 21 in the depth direction is adjusted by the storage frame position adjustment mechanism 6, the storage frame 21 is moved in the depth direction relative to the cleaning member holding portion 712, which is fixed to the vertical frame 113 of the sash frame 11 via the screen device mounting bracket 4 and the mounting bracket 5.

The length of the extension plate 7121 of the cleaning member holder 712 in the depth direction, combined with the length of the outdoor cleaning member 711 in the depth direction, is such that even when the storage frame position adjustment mechanism 6 adjusts the position of the storage frame 21 in the depth direction, the extension plate 7121 and the outdoor cleaning member 711 can cover the opening 21a formed on the lower surface of the storage frame 21, in the portion X1 on the outdoor side of the screen 23 at the opening 21a of the storage frame 21. Therefore, when the storage frame position adjustment mechanism 6 adjusts the position of the storage frame 21 in the depth direction, the extension plate 7121 and the outdoor cleaning member 711 cover the portion X1 on the outdoor side of the screen 23 at the opening 21a formed on the lower surface of the storage frame 21, thus preventing insects from entering the storage frame 21.

Next, the mounting structure for attaching the screen device 2 to the sash frame 11 of the window sash 1 using a pair of screen device mounting brackets 4, 4 will be described. As shown in Figures 3 and 4, the screen device 2 is attached to a pair of vertical frames 113, 113 of the sash frame 11 of the window sash 1 on the outdoor side X1 of the window sash 1 using a pair of screen device mounting brackets 4, 4. Furthermore, a pair of guide rails 3, 3 of the screen device 2 are positioned at both ends of the window sash 1 in the left-right direction on the outdoor side X1 of the window sash 1 and extend in the vertical direction. The screen device mounting brackets 4 and the guide rails 3 are constructed with some overlapping component parts.

As shown in Figure 4, the pair of screen device mounting brackets 4, 4 are positioned apart in the left-right direction, and fix both ends of the screen device 2's storage frame 21 in the left-right direction to the pair of vertical frames 113, 113. The screen device 2's storage frame 21 is attached to each of the pair of screen device mounting brackets 4, 4 by mounting brackets 5. The pair of screen device mounting brackets 4, 4, with the screen device 2's storage frame 21 attached by mounting brackets 5, are fixed to the pair of vertical frames 113, 113. The pair of guide rails 3, 3 are positioned at both ends of the screen 23 extended from the screen device 2 in the left-right direction.

Since the pair of screen mounting brackets 4, 4 and the pair of guide rails 3, 3 have a symmetrical structure, in this embodiment, the configuration of one side in the left-right direction (the left side in Figure 3) will be described. The configuration of the other side in the left-right direction (the right side in Figure 3) is a symmetrical version of the configuration of the left side (Figure 3), so its description will be omitted.

As shown in Figure 5, the screen device mounting bracket 4 fixes the vertical frame projection 115 of the vertical frame 113 of the sash frame 11 of the window sash 1. As shown in Figure 5, the vertical frame projection 115 has a depth-extending plate 115a, an outdoor-side plate portion 115b (plate-shaped portion) connected to the outdoor-side X1 end of the depth-extending plate 115a and extending in the left-right direction (visible direction), and a bent plate 115c that bends from the left-right outer end of the outdoor-side plate portion 115b toward the indoor-side X2. The outdoor-side plate portion 115b is formed in a plate shape extending to a predetermined length in the left-right direction (visible direction).

As shown in Figures 4 and 5, the screen device mounting bracket 4 comprises a first fixing member 41 to which the storage frame 21 of the screen device 2 (outdoor building fixture) is fixed via a mounting bracket 5; a second fixing member 42 that is combined with the first fixing member 41 to sandwich the vertical frame 113 of the sash frame 11 of the window sash 1 between itself and the first fixing member 41; and a screw 43 (fastening member) that fastens the first fixing member 41 and the second fixing member 42 together.

As shown in Figure 4, the first fixing member 41 and the second fixing member 42 are positioned on the outer periphery of the opening of the sash frame 11 in the left-right direction, and extend outward from the opening of the sash frame 11 in the vertical direction. The first fixing member 41 and the second fixing member 42 extend vertically over substantially the entire area in the direction in which the vertical frame 113 extends. The first fixing member 41 and the second fixing member 42 extend vertically over the entire area including the range in which the screen 23 of the screen device 2 is pulled out. The first fixing member 41 and the second fixing member 42 are formed, for example, from extruded profiles made of aluminum. The first fixing member 41 is also part of the guide rail 3. The guide rail 3 comprises an outer guide rail component 30, which consists of the first fixing member 41 and the outer guide rail component 31, and an inner rail 32, which is positioned inside the outer guide rail component 30.

As shown in Figure 5, the first fixing member 41 includes a visible-direction extending guide portion 4111 extending in the left-right direction on the indoor side X2, an intermediate projection portion 4112 projecting outwards from a portion of the visible-direction extending guide portion 4111 in the left-right direction to the outdoor side X1, a depth-direction extending guide portion 4113 extending outwards from the left-right outer end of the visible-direction extending guide portion 4111 to the outdoor side X1, an indoor-side projection portion 4114 projecting outwards from the left-right outer end of the visible-direction extending guide portion 4111 to the indoor side X2, and a hook connected to the left-right inner side of the end of the indoor-side projection portion 4114 on the indoor side X2. It comprises a hanging portion 4115, an indoor-side visible-direction extension portion 4116 extending outward in the left-right direction from the indoor-side end X2 of the indoor-side projection portion 4114, an end projection portion 4117 projecting outward in the left-right direction from the outdoor-side end X1 of the depth-direction extension guide portion 4113, an outer extension portion 4118 extending outward in the left-right direction from the middle of the depth-direction extension guide portion 4113, an outdoor-side extension portion 4119 extending to the outdoor-side X1 from the left-right outer end of the outer extension portion 4118, and an arc-shaped connecting portion 4120 formed at the outdoor-side end X1 of the outdoor-side extension portion 4119.

The hook portion 4115 is positioned to hook onto the end of the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113, opposite to the second fixing member 42, when the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113 is sandwiched in the depth direction and the visible direction by the first fixing member 41 and the second fixing member 42. The hook portion 4115 is formed in a U-shape that opens outward in the left-right direction of the screen device 2. The hook portion 4115 is formed in a U-shape that is folded back outward in the left-right direction of the screen device 2 at the inner end in the left-right direction (visible direction) of the plate material that extends inward in the left-right direction (visible direction) from the end of the indoor side X2 of the indoor side projection 4114.

The width of the U-shaped, horizontally extending space in the hook portion 4115 is formed to a width sufficient for the insertion of the outdoor-side plate portion 115b (plate-like portion) of the vertical frame projection 115 of the vertical frame 113. The inner ends of the outdoor-side plate portion 115b of the vertical frame projection 115 of the vertical frame 113 are positioned inside the U-shaped portion of the hook portion 4115. As a result, the inner ends of the outdoor-side plate portion 115b of the vertical frame projection 115 of the vertical frame 113 are hooked and positioned within the hook portion 4115.

The indoor-facing extension portion 4116 extends outward in the left-right direction from the plate portion of the U-shaped outdoor-facing X1 of the hook portion 4115. The indoor-facing extension portion 4116 is positioned along the outdoor-facing X1 surface of the outdoor-facing plate portion 115b of the vertical frame projection 115 of the vertical frame 113.

As shown in Figures 2 and 4, the first fixing member 41 of the screen device mounting fixture 4 is fixed to the storage frame 21 of the screen device 2 by a mounting bracket 5 at the upper end of the first fixing member 41. As shown in Figure 6, the vertically extending portion 51 of the mounting bracket 5 is positioned on the outdoor side X1 of the outer extension portion 4118 of the first fixing member 41 at the upper end of the first fixing member 41. The vertically extending portion 51 of the mounting bracket 5 is positioned along the outdoor side X1 of the outer extension portion 4118 and is fixed to the outer extension portion 4118 of the first fixing member 41 of the screen device mounting fixture 4 by screws 51a (fastening members). The protruding plate 53 of the mounting bracket 5 is fixed to the mounting plate 213 positioned on the left-right end side of the storage frame 21 of the screen device mounting fixture 4 by screws 53a (fastening members). As a result, the storage frame 21 of the screen device mounting bracket 4 is fixed to the first fixing member 41 of the screen device mounting bracket 4 by the mounting bracket 5.

As shown in Figure 5, the second fixing member 42 is arranged in combination with the first fixing member 41. The second fixing member 42 includes: a second fixing member visible-direction extension portion 4211 extending in the left-right direction between the indoor-side visible-direction extension portion 4116 and the outdoor-side extension portion 4119 of the first fixing member 41; an indoor-side extension portion 4212 extending from the left-right outer end of the second fixing member visible-direction extension portion 4211 toward the indoor side X2; an inner extension portion 4213 extending inward in the left-right direction from the indoor-side X2 end of the indoor-side extension portion 4212; a folded-back projection portion 4214 bending and protruding from the left-right inner end of the inner extension portion 4213 toward the outdoor side X1; and an outdoor-side extension portion 4215 extending from the left-right outer end of the second fixing member visible-direction extension portion 4211 toward the outdoor side X1.

The second fixing member's visible-direction extending portion 4211 extends horizontally parallel to the indoor-side visible-direction extending portion 4116 and the outward-extending portion 4118 of the first fixing member 41, between them.

The portion of the indoor extension 4212 on the indoor side X2 is positioned along the left-right outer surface of the bent plate 115c of the vertical frame projection 115 of the vertical frame 113. The indoor extension 4213 is positioned on the indoor side X2 of the left-right outer portion of the bent plate 115c and the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113, extending inward in the left-right direction from the end of the indoor side X2 of the indoor extension 4212, and extending left-right to the left-right outer surface of the depth-extending plate 115a of the vertical frame projection 115 of the vertical frame 113.

The folded projection 4214 extends from the inner end of the inner extension 4213 in the left-right direction towards the outdoor side X1, along the left-right outer surface of the projection plate 115a of the vertical frame 113. The outdoor side X1 end of the folded projection 4214 abuts against the indoor side X2 surface of the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113.

As a result, the first fixing member 41 and the second fixing member 42 are positioned to sandwich the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113 in both the depth and visibility directions. With the first fixing member 41 and the second fixing member 42 sandwiching the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113 in both the depth and visibility directions, the hook portion 4115 is positioned to hook the inner ends of the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113 in the left-right direction.

The screws 43 fasten the first fixing member 41 and the second fixing member 42 together, with the outdoor-facing plate portion 115b of the vertical frame projection 115 of the vertical frame 113 sandwiched between the first fixing member 41 and the second fixing member 42 in both the depth direction and the visibility direction. As shown in Figure 4, multiple screws 43 are provided at positions separated vertically from the first fixing member 41 and the second fixing member 42, and they secure the first fixing member 41 and the second fixing member 42.

As shown in Figure 5, the screw 43 is formed extending in the depth direction and is positioned to be screwed into the outer extension portion 4118 of the first fixing member 41 and the second fixing member 4211 extending in the direction of the second fixing member by moving from the outdoor side X1 to the indoor side X2, thereby penetrating the outdoor extension portion 4119 of the first fixing member 41 and the second fixing member 4211 extending in the direction of the second fixing member. With the tip of the screw 43 in contact with the outdoor surface X1 of the indoor-facing extension portion 4116 of the first fixing member 41, the screw 43 is rotated, and the screw groove on the shaft of the screw 43 pulls the second fixing member 4211 in the outdoor-facing direction toward the outdoor surface X1, thereby moving the second fixing member 42 toward the outdoor surface X1, and the outdoor plate portion 115b of the vertical frame projection 115 of the vertical frame 113 is sandwiched and fixed between the outdoor surface X1 end of the folded projection 4214 of the second fixing member 42 and the indoor-facing extension portion 4116 of the first fixing member 41. As a result, the outdoor-side plate portion 115b of the vertical frame protrusion 115 of the vertical frame 113 is sandwiched in the projection direction between the outdoor-side X1 end of the folded-back protrusion 4214 of the second fixing member 42 and the indoor-side projection direction extension portion 4116 of the first fixing member 41, and is fixed in a state where movement in the projection direction is restricted.

Furthermore, the outdoor-facing plate portion 115b of the vertical frame projection 115 of the vertical frame 113 is positioned such that, in the left-right direction (visible direction), its inner end is hooked onto the hook portion 4115, restricting its movement inward in the left-right direction, while its outer end is restricted from moving outward in the left-right direction by the inner surface of the indoor-facing extension portion 4212 of the second fixing member 42. As a result, the outdoor-facing plate portion 115b of the vertical frame projection 115 of the vertical frame 113 is positioned between the hook portion 4115 of the first fixing member 41 and the indoor-facing extension portion 4212 of the second fixing member 42, and is fixed in a state where its movement in the visible direction is restricted.

The mounting structure of the guide rail 3 will now be described. As shown in Figure 5, the guide rail 3 comprises a guide rail outer component 30 (outer component) consisting of a first fixing member 41 (outer main body) and a guide rail outdoor component 31 (guide rail cover), and an internal rail 32 arranged inside the guide rail outer component 30. The first fixing member 41 constitutes the indoor side X2 portion and the left-right outer portion of the guide rail 3. The first fixing member 41 is positioned exposed to the outside of the indoor side X2 portion of the guide rail 3. The guide rail outdoor component 31, which constitutes the outdoor side X1 portion of the guide rail 3, is attached to the outdoor side X1 portion of the first fixing member 41.

As shown in Figure 5, the outdoor guide rail member 31 has an outdoor guide member lateral extension portion 311 extending in the left-right direction, an intermediate projection portion 312 projecting to the indoor side X2 from the middle of the outdoor guide member lateral extension portion 311 in the left-right direction, an engaging projection portion 313 projecting to the indoor side X2 from a portion of the outdoor guide member lateral extension portion 311 that is further out in the left-right direction than the intermediate projection portion 312, and an arc-shaped locking portion 314 projecting to the indoor side X2 from the outer end of the outdoor guide member lateral extension portion 311 in the left-right direction. The end projection portion 4117 of the first fixing member 41 engages with the base portion of the engaging projection portion 313. The arc-shaped connecting portion 4120 of the first fixing member 41 is rotatably connected to and locked to the arc-shaped locking portion 314. As a result, the guide rail exterior member 31 is rotatably connected to the first fixing member 41, as shown in Figure 11, and by rotating relative to the first fixing member 41, the interior of the first fixing member 41 can be opened.

To prevent the outer component 30 of the guide rail from sliding off, a cap 33 is provided at the lower end of the guide rail 3, as shown in Figure 2. The cap 33 comprises a bottom plate 331 and a mounting piece 332 that protrudes upward from the upper surface of the bottom plate 331. The cap 33 is fixed to the lower end of the guide rail 3 by a screw 332a, which secures the mounting piece 332 to the lower end of the guide rail 3.

As shown in Figure 5, the internal rail 32 is positioned inside the outer guide rail component 30, with its inward movement in the left-right direction restricted by the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the outer guide rail component 31. The internal rail 32 guides the screen 23 so that it can move vertically, which is the pulling direction, while engaging the edge member 231 located at the end of the screen 23 in a direction perpendicular to the pulling direction.

As shown in Figure 5, the internal rail 32 has a hollow frame portion 323 and a pair of protruding portions 324 (regulating protrusions) that project outwards to the outdoor side X1 and indoor side X2 at the left-right outer ends of the hollow frame portion 323.

The hollow frame portion 323 is positioned between the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the guide rail exterior member 31. The hollow frame portion 323 has a hollow portion 321 formed inside and a communication groove portion 322 that connects the inside and outside of the hollow portion 321. The edge member 231, positioned at the end of the screen 23 in a direction perpendicular to the screen's extension direction, is positioned within the hollow portion 321 of the hollow frame portion 323, and the left and right end portions of the screen 23 (the ends perpendicular to the extension direction) are passed through the communication groove portion 322. It is then locked to the internal rail 32 and guided by the guide rail 3. The hollow portion 321 inside the hollow frame portion 323 constitutes the guide groove 32a of the internal rail 32.

The pair of protrusions 324 have an outdoor protrusion plate 324a that protrudes outward in the indoor-outdoor direction (depth direction) X1, overlapping with the intermediate protrusion 312 of the guide rail outdoor member 31 when viewed in the left-right direction, and an indoor protrusion plate 324b that protrudes inward in the indoor-outdoor direction (depth direction) X2, overlapping with the intermediate protrusion 4112 of the first fixing member 41 when viewed in the left-right direction.

The pair of protrusions 324 are restricted from moving inward in the left-right direction by the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the guide rail exterior member 31 in the guide rail exterior component 30. As a result, the internal rail 32 is positioned inside the guide rail exterior component 30 with the pair of protrusions 324 restricted from moving inward in the left-right direction relative to the guide rail exterior component 30 by the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the guide rail exterior member 31.

With the internal rail 32 positioned inside the guide rail 3, the arc-shaped locking portion 314 of the guide rail outdoor member 31 is connected to the arc-shaped connecting portion 4120 of the first fixing member 41 in a rotatable manner. Therefore, the guide rail outdoor member 31 can be rotated around the arc-shaped locking portion 314. As a result, as shown in Figure 5, in the guide rail outer component 30, the engagement of the end projection 4117 of the first fixing member 41, which is engaged with the base portion of the engaging projection 313, can be released. By rotating the guide rail outdoor member 31 around the arc-shaped locking portion 314, as shown in Figure 11, the guide rail outdoor member 31 can be rotated to an open state.

Furthermore, by exposing the outdoor side X1 inside the outer guide rail component 30, the interior of the outer guide rail component 30 can be opened. This allows, for example, even if the edge member 231, positioned at the end perpendicular to the screen 23's extension direction, becomes trapped in the inner rail 32, the inner rail 32 can be exposed to the outdoor side X1 by rotating the outer guide rail component 31 around the arc-shaped locking portion 314. Therefore, the trapped edge member 231 of the screen 23 can be easily resolved by removing the inner rail 32 without disassembling the screen device 2.

By rotating the guide rail outdoor member 31 around the arc-shaped locking portion 314, the inner rail 32 is exposed to the outdoor side X1. After removing the inner rail 32 and relieving the screen 23 from being pinched, as shown in Figure 11, the guide rail outdoor member 31 can be rotated from an open state to a closed state around the arc-shaped locking portion 314 in the guide rail outer component 30, as shown in Figure 5. Then, by engaging the end projection 4117 of the first fixing member 41 with the base portion of the engaging projection 313, the guide rail outdoor member 31 can be easily attached to the first fixing member 41.

Here, when the guide rail outdoor member 31 is rotated to a closed position, the intermediate protrusion 312 of the guide rail outdoor member 31 is positioned inward in the left-right direction of the outdoor protrusion plate 324a of the inner rail 32. Therefore, with the inward movement of the outdoor protrusion plate 324a of the inner rail 32 restricted, the guide rail outdoor member 31 can be easily attached to the first fixing member 41. Furthermore, because the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the guide rail outdoor member 31 restrict the inward movement of the pair of protrusions 324 of the inner rail 32 in the left-right direction, the guide rail outdoor member 31 can be attached to the first fixing member 41 in a way that prevents the inner rail 32 from easily detaching from the guide rail outer component 30.

When fixing the screen device 2 to the sash frame 11 of the window sash 1, first, with the window sash 1 attached to the opening 100a of the building structure 100, the pair of screen device mounting brackets 4, 4 are fixed to the pair of vertical frames 113, 113 of the sash frame 11, as shown in Figures 4 and 5. Specifically, as shown in Figure 5, the outdoor side plate portion 115b of the vertical frame 113 is sandwiched between the first fixing member 41 and the second fixing member 42, and the first fixing member 41 and the second fixing member 42 are fastened and fixed with screws 43.

Next, as shown in Figures 2 and 6, the vertically extending portion 51 of the mounting bracket 5, which is fixed to the storage frame 21 of the screen device 2, is fixed to the first fixing member 41 of the screen device mounting fixture 4. Then, the guide rail outdoor member 31 is attached to the outdoor side X1 of the first fixing member 41. This allows the screen device 2 to be easily attached to the sash frame 11 using the screen device mounting fixture 4, while minimizing misalignment in the left-right (visible) and depth directions.

This embodiment provides the following advantages. The screen device 2 of this embodiment comprises a storage frame 21, a screen 23 that can be pulled out from and retracted into the storage frame 21, and an outdoor cleaning member 711 positioned in contact with the outdoor surface X1 of the screen 23. As a result, since the outdoor cleaning member 711 is positioned in contact with the outdoor surface X1 of the screen 23, the outdoor surface X1 of the screen 23 can be easily cleaned.

Furthermore, in this embodiment, the outdoor cleaning member 711 is held in place by a cleaning member mounting groove 7124, and the outdoor cleaning member 711 can be attached to and detached from the cleaning member mounting groove 7124 by sliding it along the groove. Therefore, by sliding the outdoor cleaning member 711 along the groove 7124, it can be easily cleaned or replaced with a new one. This makes it easy to suppress the decrease in the dust and dirt adsorption capacity of the outdoor cleaning member 711.

Furthermore, in this embodiment, the outdoor cleaning member 711 is positioned at the opening 21a of the storage frame 21 through which the screen 23 is extended and retracted. By providing the outdoor cleaning member 711 at the opening 21a of the storage frame 21 through which the screen 23 passes, the outdoor cleaning member 711 can efficiently clean the outdoor surface X1 of the screen 23.

Next, a second embodiment will be described. As shown in Figure 12, in addition to the configuration of the first embodiment shown in Figure 8, the second embodiment is further provided with an indoor cleaning member 721 (second cleaning member) at the extension opening 21a (screen extension section) formed on the lower surface of the storage frame 21 of the screen device 2. The indoor cleaning member 721 is positioned on the indoor side X2 of the screen 23 at the extension opening 21a of the storage frame 21. The indoor cleaning member 721 is made of, for example, a mohair material. The tip of the indoor cleaning member 721 is positioned to abut the surface of the indoor side X2 of the screen 23 when the screen 23 is pulled out or retracted. The indoor cleaning member 721 is attached to the upper frame 111 of the sash frame 11 while being held by the cleaning member holding section 722.

The cleaning member holding portion 722 is formed extending in the left-right direction. As shown in Figure 12, the cleaning member holding portion 722 includes a visible-direction extending plate 7221 extending in the vertical direction, a hook piece 7222 provided on the indoor side X2 of the lower end of the visible-direction extending plate 7221 and opening upward, an outdoor-side projection portion 7223 projecting from the upper end of the visible-direction extending plate 7221 to the outdoor side X1, and a cleaning member mounting groove 7224 (holding groove) positioned at the outdoor-side end of the outdoor-side projection portion 7223.

The visible-direction extending plate 7221 is positioned along the outdoor-side X1 surface of the outdoor-side end downward extension plate 1111, which extends downward at the outdoor-side X1 end of the upper frame 111 of the sash frame 11, and is fixed to the outdoor-side X1 surface of the outdoor-side end downward extension plate 1111 of the upper frame 111 by screws 722a.

The lower end of the downward extension plate 1111 on the outdoor side of the upper frame 111 of the sash frame 11 is positioned at the upward-opening portion of the hook piece 7222. As a result, the hook piece 7222 is hooked onto the lower end of the downward extension plate 1111 on the outdoor side of the upper frame 111 of the sash frame 11.

The cleaning member mounting groove 7224 is formed in a C-shape in cross-section, opening towards the outdoor side X1, and extends horizontally across the entire longitudinal area of the cleaning member holding portion 722. The cleaning member mounting groove 7224 holds the indoor cleaning member 721. The indoor cleaning member 721 is detachably attached to the cleaning member mounting groove 7224.

The indoor cleaning member 721 has a mounting plate 7211 attached to the cleaning member mounting groove 7224, and a cleaning portion 7212 protruding from the mounting plate 7211 to the outdoor side X1. The cleaning portion 7212 is, for example, mohair. The indoor cleaning member 721 is detachable from the cleaning member holding portion 722 by sliding the mounting plate 7211 in the left-right direction along the cleaning member mounting groove 7224.

In the second embodiment, the outdoor cleaning member 711 is positioned in contact with the outdoor surface X1 of the screen 23, and the indoor cleaning member 721 is positioned in contact with the indoor surface X2 of the screen 23. Therefore, both the outdoor surface X1 and the indoor surface X2 of the screen 23 can be easily cleaned simultaneously.

While preferred embodiments of this disclosure have been described above, this disclosure is not limited to the embodiments described above and can be modified as appropriate.

For example, in the first embodiment, the vertical frame projection 115 of the vertical frame 113 is configured to have a bent plate 115c that bends from the left-right outer end of the outdoor side plate portion 115b toward the indoor side X2, but is not limited to this. The vertical frame projection 115 of the vertical frame 113 does not have to have a bent plate 115c that bends from the left-right outer end of the outdoor side plate portion 115b toward the indoor side X2, and in the case of a vertical frame projection 115 of a vertical frame 113 that does not have a bent plate 115c, the first fixing member 41 and the second fixing member 42 may be fastened together with screws 43 (fastening members) while the outdoor side plate portion 115b of the vertical frame 113 is sandwiched between the first fixing member 41 and the second fixing member 42 in the depth direction and the visible direction. In this case as well, similar to the embodiment, even if the screws loosen, the positional displacement of the vertical frame 113 of the sash frame 11 in both the depth and visibility directions is suppressed, and the outdoor side plate portion 115b of the vertical frame projection 115 of the vertical frame 113 of the sash frame 11 can be firmly fixed by the first fixing member 41 and the second fixing member 42.

In the first embodiment, the screen 23 of the screen unit 2 is configured to be movable in the vertical direction, but this is not limited to this. The screen 23 of the screen unit 2 may also be configured to be movable in the horizontal direction.

In the first embodiment described above, the screen 23 of the screen device 2 was formed in a sheet shape using a mesh-like material, but it is not limited to this. The screen 23 of the screen device 2 may also be formed in a sheet shape using a material other than a mesh-like material.

In the first embodiment described above, the window of the window sash 1 (joinery) located on the interior side X2 of the screen device 2 was configured with a sliding sash 12 that can move left and right, but the embodiment is not limited to this. For example, the window of the window sash 1 (joinery) located on the interior side of the screen device may be configured as a push-open type window.
