[0003] [Patent Document 1] Japanese Patent Application Publication No. 2018-3273 Summary of the Invention [Problem to be solved by the invention]

[0004] In the screen device described in Patent Document 1, if a strong force is applied to the screen, the locking portion provided on the end of the screen in a direction perpendicular to the direction of pulling out the screen may become pinched inside the guide rail, causing the screen to stop operating. In this case, disassembling the screen device is required to release the locking portion of the end of the screen from being pinched. Because disassembling the screen device is complicated, there is a need for a method that can easily release the locking portion of the end of the screen from being pinched between the guide rails without disassembling the guide rails.

[0005] The present disclosure aims to provide a screen device that can easily release the pinching of the end of a screen in a direction perpendicular to the pull-out direction when the end of the screen is pinched between guide rails.

[0006] The present disclosure relates to a screen device comprising: a screen storage section; a screen that can be pulled out from the screen storage section and pulled into the screen storage section for storage; and a pair of guide rails that guide both ends of the screen in a direction perpendicular to the direction in which the screen is pulled out, wherein the screen has a pair of locking sections that are provided at both ends in the direction perpendicular to the direction in which the screen is pulled out and are guided by the guide rails while being locked to the guide rails inside the guide rails, and the guide rails have an outer component, which has an outer main body section and a guide rail cover section that is rotatably connected to the outer main body section and can open the inside of the outer main body section by rotating relative to the outer main body section.

DETAILED DESCRIPTION OF THE INVENTION

[0008] An embodiment of the present disclosure will be described in detail below with reference to the drawings. In this specification, the term "front view direction" refers to the face direction of the shoji screen 12 of the window sash 1 attached to the opening 100a of the building skeleton 100 or the face direction of the screen 23 pulled out from the storage frame 21 of the screen device 2. The term "front view direction" refers to the thickness direction of the shoji screen 12 or the thickness direction of the screen 23 pulled out from the storage frame 21 of the screen device 2. In the front view direction, the left and right directions are referred to as the left-right direction. The "front view surface" refers to the surface of the window sash 1 or the screen device 2 facing the outside and inside, respectively, and the "front view surface" refers to the surface of the window sash 1 or the screen device 2 extending in the indoor-outdoor direction. In the drawings, the outside view is referred to as "outdoor side X1" and the inside view is referred to as "indoor side X2."

[0009] The mounting structure of a screen unit 2 (outdoor fitting) of the first embodiment will be described. As shown in Figs. 1 to 3, the screen unit 2 is mounted on an outdoor side X1 of a window sash 1 (fitting) that is mounted to an opening 100a of a building skeleton 100. In this embodiment, the screen unit 2 is a type of screen unit in which a screen 23 is pulled downward from a storage frame 21 disposed at the top. As shown in Figs. 3 and 4, the screen unit 2 is mounted on the outdoor side X1 of a sash frame 11 of the window sash 1 by a screen unit mounting fixture 4 (outdoor fitting mounting fixture). The screen unit mounting fixture 4 fixes the screen unit 2 to the outdoor side X1 of the sash frame 11.

[0010] We will now explain the window sash 1. The window sash 1 is attached to an opening 100a in a building skeleton 100, and as shown in Figures 1 to 3, comprises a rectangular sash frame 11 and two shoji screens 12, 12. The sash frame 11 is attached to the opening 100a in the building skeleton 100, and has an upper frame 111, a lower frame 112, and a pair of vertical frames 113, 113 (sash frames), which are assembled together to form a rectangular shape. The shoji screens 12, 12 are configured as double sliding windows that can slide left and right within the sash frame 11, and can open and close the opening of the sash frame 11.

[0011] As shown in Fig. 3, each of the pair of vertical frames 113 has a vertical frame main body 114 and a vertical frame protrusion 115. The vertical frame main body 114 is disposed on the outside of the left-right end of the shoji screen 12 and extends in the viewing direction. The vertical frame protrusion 115 protrudes from the end of the vertical frame main body 114 on the outside side X1 toward the outside side X1. The screen unit 2 is fixed to the vertical frame protrusion 115 via a screen unit mounting fixture 4, as will be described in detail later.

[0012] The screen unit 2 will now be described. As shown in Figs. 1 to 3, the screen unit 2 is disposed on the outdoor side X1 of the sash frame 11 of the window sash 1. The screen unit 2 includes a storage frame 21 (screen storage section), a winding shaft 22 (see Fig. 2) stored in the storage frame 21, a screen 23 that can be wound around the winding shaft 22 and pulled out downward from the winding shaft 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 cleaning member 711 (first cleaning member) provided at an outlet 21a formed on the underside of the storage frame 21.

[0013] As shown in Figures 3 to 5, the storage frame 21 of the screen unit 2 is attached to a pair of vertical frames 113, 113 of the sash frame 11 of the window sash 1 via the screen unit fixture 4 by screwing screws 43 in the forward direction from the front of the outside-door side X1. The screws 43 are screwed in the forward direction from the front of the outside-door side X1. This makes it possible to easily fix the screen unit fixture 4 to the sash frame 11 even when one or both of the left and right sides of the target opening are recessed corners and it is difficult to secure working space. The mounting structure of the screen unit 2 will be described in detail later.

[0014] As shown in Fig. 2, the storage frame 21 is provided on the outdoor side X1 of the upper portion of the opening 100a of the building skeleton 100, and is disposed above the outdoor side X1 of the upper frame 111 of the sash frame 11. The back surface (the surface facing the indoor side X2) of the storage frame 21 is disposed in contact with the outer wall surface 101a of the outdoor side X1 above the opening 100a of the building skeleton 100. The storage frame 21 is attached by being fixed to a pair of vertical frames 113, 113 of the sash frame 11 of the window sash 1 via the mounting bracket 5 and the screen device mounting fixture 4, while being disposed in contact with the outer wall surface 101a of the outdoor side X1 of the building skeleton 100 at the upper portion of the periphery of the opening 100a of the building skeleton 100.

[0015] 1 and 2, the storage frame 21 is formed in a box shape extending in the left-right direction. As shown in Fig. 1, the storage frame 21 has a storage frame main body 211 and a pair of end cap members 212 attached to both left-right ends of the storage frame main body 211. As shown in Fig. 2, the lower surface of the storage frame 21 is formed with a feed-out opening 21a (screen feed-out portion) that opens downward and extends in the left-right direction.

[0016] The storage frame 21 is connected to the screen unit mounting fixture 4 via mounting brackets 5. As shown in FIGS. 2 and 4, the mounting brackets 5 are arranged at both left-right ends of the screen unit mounting fixture 4 and connect the storage frame 21 and the screen unit mounting fixture 4 at both left-right ends of the screen unit mounting fixture 4. The mounting bracket 5 is formed in an L shape that is open downward on the outside side X1. As shown in FIG. 2, the mounting bracket 5 has a vertical extending portion 51 that extends in the vertical direction, an outdoor extension plate 52 that bends and extends from the upper end of the vertical extending portion 51 toward the outside side X1, and a protruding plate 53 that protrudes upward by a predetermined width from the outer left-right end of the outdoor extension plate 52.

[0017] 6, the vertical extending portion 51 is fixed to a first fixing member 41 (described later) of the screen unit attachment fixture 4 by a screw 51a (fastening member). The protruding plate 53 is fixed to an attachment plate 213 arranged on the left-right end side of the storage frame 21 of the screen unit attachment fixture 4 by a screw 53a (fastening member).

[0018] The storage frame 21 has a storage frame position adjustment mechanism 6 (position adjustment mechanism) that can adjust the mounting position in the front direction according to the front direction positions Xa, Xb, and Xc of the exterior wall surfaces 101a, 101b, and 101c (see FIGS. 8 to 10) on the outside side X1 of the building skeleton 100. The storage frame position adjustment mechanism 6 will be described in detail later.

[0019] 2, a winding shaft 22 is stored inside the storage frame 21. The storage frame 21 stores the screen 23 so that the screen 23 can be wound in and unwound by being wound around the winding shaft 22 and being pulled out from the winding shaft 22.

[0020] The winding shaft 22 is disposed inside the storage frame 21, above the opening 100a of the building skeleton 100. The winding shaft 22 is formed to extend in the left-right direction and is configured to be rotatable around a central axis extending in the left-right direction. A base end of the screen 23 is fixed to the winding shaft 22, and the winding shaft 22 is configured to be able to wind up the screen 23. The winding shaft 22 is biased by a biasing member (not shown) that biases the screen 23 in the winding direction so as to rotate the screen 23 in the winding direction. For example, a spring-type coil spring or the like can be used as the biasing member.

[0021] The screen 23 is formed into a sheet shape using, for example, a resin mesh. The screen 23 is pulled downward from an outlet 21a formed on the bottom surface of the storage frame 21. The base end of the screen 23 is fixed to the winding shaft 22, and the screen 23 is wound around 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 pulled into the storage frame 21 for storage.

[0022] Conventionally, when a sliding screen door is installed on the exterior side of a window sash, the sliding screen door is attached to the window frame, which prevents sunlight from entering the room and allows insects to enter the room through the gap between the screen door and the shoji screen. In contrast, in this embodiment, a screen device 2 having a sheet-like screen 23 made of a mesh body is placed on the exterior side X1 of the window sash 1. This allows the screen 23 to be stored in the storage frame 21 when fully opened, improving sunlight acquisition, ventilation performance, and visibility. Furthermore, when the screen 23 is fully closed, the mesh body of the screen 23 covers the front surface of the window sash 1 from the exterior side X1, thereby improving insect prevention performance. Furthermore, covering the front surface of the window sash 1 from the exterior side X1 with the mesh body of the screen 23 improves sunlight blocking performance, improves insulation performance, and also blocks ultraviolet rays. In particular, in this embodiment, by placing the screen device 2, in which the screen 23 is formed in a sheet-like shape using a mesh body, on the outdoor side X1 of the window sash 1, it is possible to improve the sun shading performance compared to when the screen device is placed on the indoor side X2 of the window sash 1.

[0023] 5, a pair of edge members 231, 231 (locking portions) are provided at both ends of the screen 23 in the left-right direction (the direction perpendicular to the pull-out direction). The pair of edge members 231 provided at both ends of the screen 23 in the left-right direction are arranged to be slidable in the up-down direction while being locked in guide grooves 32a of inner rails 32 arranged 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 inside the pair of guide rails 3, 3 while being locked by the pair of guide rails 3, 3.

[0024] 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 engaged with the attachment 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 engaged with the attachment groove 242a of the movable frame 24.

[0025] 1 and 2, the movable frame 24 is fixed to the lower end of the screen 23, and is thereby disposed at the leading end in the pull-out direction of the screen 23. The movable frame 24 also functions as a grip that is held by the user when opening or closing the screen 23.

[0026] The movable frame 24 is configured to be movable in the vertical direction 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 screen 23 is in the closed position where the screen opening 2a is closed, the movable frame 24 is disposed opposite the visible surface of the outside side X1 of the lower frame 112. The movable frame 24 is urged toward the storage frame 21 by a urging member (not shown) that urges the screen 23 in the direction of rolling up.

[0027] As shown in FIG. 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 FIG. 4).

[0028] The external frame portion 241 is formed in a frame shape that extends in the left-right direction and opens upward, and a blocking member mounting groove 241a (mounting groove) to which a mohair member 25 (blocking member) is attached is formed on the visible surface on the indoor side X2 of the lower end of the external frame portion 241. The blocking member mounting groove 241a is formed in a groove shape that is recessed from the surface on the indoor side X2 of the lower end of the external frame portion 241 to the outdoor side X1 and extends in the left-right direction.

[0029] As shown in Figure 7, a mohair member 25 (blocking member) is attached to a blocking member attachment groove 241a formed on the indoor side X2 surface of the movable frame 24. The mohair member 25 protrudes toward the indoor side X2 from the indoor side X2 surface of the lower end of the external frame portion 241 and extends in the left-right direction. The mohair member 25 has an attachment plate 251 attached to the blocking member attachment groove 241a and a mohair portion 252 protruding from the attachment plate 251 toward the indoor side X2.

[0030] When the screen 23 is pulled out and positioned in the closed position with the movable frame 24 positioned on the outdoor side X1 of the lower frame 112, the mohair member 25 protrudes from the indoor side X2 surface of the movable frame 24 toward the indoor side X2 towards the facing 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 facing 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 facing surface 1121 of the outdoor side X1 of the lower frame 112, or it may be positioned close enough to prevent insects from entering the facing surface 1121 of the outdoor side X1 of the lower frame 112 without contacting it.

[0031] The screen end holding portion 242 is disposed in a portion of the outer frame portion 241 that is open upward. The screen end holding portion 242 holds an edge member 233 attached to the lower end of the screen 23. The screen end holding portion 242 has a communicating portion 242b that is open at the upper end and extends in the vertical direction, and an attachment groove 242a formed at the lower end of the communicating portion 242b. With the lower end of the screen 23 passed through the communicating portion 242b, the edge member 233 attached to the lower end of the screen 23 is engaged in the attachment groove 242a of the screen end holding portion 242.

[0032] 1, the pair of guide rails 3, 3 are provided at both ends in a direction perpendicular to the pull-out direction of the screen 23, and extend in the pull-out direction of the screen 23. Specifically, the pair of guide rails 3, 3 are formed to extend in the up-down direction at both left-right ends of the exterior side X1 of the window sash 1. The pair of guide rails 3, 3 are arranged outer circumferentially relative to the opening of the sash frame 11 in the left-right direction, and are formed to extend outer circumferentially relative to the opening of the sash frame 11 in the up-down direction.

[0033] The pair of guide rails 3, 3 guide both ends of the screen 23 in a direction perpendicular to the pull-out direction. The pair of guide rails 3, 3 support both left-right ends of the movable frame 24 so that they can slide up and down, and also guide both left-right ends of the screen 23 so that they can slide up and down when the screen 23 moves up and down.

[0034] Next, the outdoor cleaning member 711 provided at the feeding opening 21a formed on the underside of the storage frame 21 will be described. As shown in FIG. 8, the outdoor cleaning member 711 (first cleaning member) is provided at the feeding opening 21a formed on the underside of the storage frame 21. The outdoor cleaning member 711 is arranged on the outdoor side X1 of the screen 23 at the feeding opening 21a of the storage frame 21. The outdoor cleaning member 711 is made of mohair, for example. The tip of the outdoor cleaning member 711 is arranged so that it abuts against the surface of the outdoor side X1 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 a cleaning member holding portion 712.

[0035] The cleaning element holding portion 712 is formed to extend in the left-right direction. The cleaning element holding portion 712 is arranged inside the storage frame 21 above the feeding opening 21a of the storage frame 21 so as to close the feeding opening 21a formed in the bottom surface of the storage frame 21.

[0036] The cleaning element holding portion 712 has a forward extension plate 7121 extending in the forward direction above the feed-out opening 21a formed on the underside of the storage frame 21, an outdoor downward protruding portion 7122 protruding downward from the outdoor side X1 end of the forward extension plate 7121, an indoor side downward protruding portion 7123 protruding downward from the indoor side X2 end of the forward extension plate 7121, and a cleaning element mounting groove 7124 (holding groove) arranged on the indoor side X2 surface of the indoor side downward protruding portion 7123.

[0037] The length in the prospective direction of the prospective extension plate 7121 is such that the sum of the length in the prospective direction of the prospective extension plate 7121 of the cleaning element holding portion 712 and the length in the prospective direction of the outdoor cleaning element 711 can close the outlet 21a formed on the underside of the storage frame 21 with the prospective extension plate 7121 and the outdoor cleaning element 711, even if the position of the storage frame 21 in the prospective direction changes due to a storage frame position adjustment mechanism 6 (position adjustment mechanism) of the storage frame 21, which will be described later, in the portion of the outlet 21a of the storage frame 21 that is further outside X1 than the screen 23. The prospective extension plate 7121 is fixed to the outdoor extension plate 52 of the mounting bracket 5 with screws 712a (fastening members). The forward extending plate 7121 and the outdoor cleaning member 711 block the portion of the outlet 21a formed on the underside of the storage frame 21 closer to the outdoor side X1 than the screen 23, thereby preventing insects from entering the storage frame 21.

[0038] The cleaning element mounting groove 7124 has a C-shaped cross section that opens toward the indoor side X2, and extends left and right over the entire longitudinal length of the cleaning element holding portion 712. The cleaning element mounting groove 7124 holds the outdoor cleaning element 711. The outdoor cleaning element 711 is removably mounted in the cleaning element mounting groove 7124.

[0039] The outdoor cleaning element 711 has a mounting plate 7111 attached to the cleaning element mounting groove 7124, and a cleaning part 7112 protruding from the mounting plate 7111 toward the indoor side X2. The cleaning part 7112 is made of mohair, for example. The outdoor cleaning element 711 can be attached to and detached from the cleaning element holding part 712 by sliding the mounting plate 7111 left and right along the cleaning element mounting groove 7124.

[0040] The cleaning element holding part 712 is fixed to the mounting bracket 5 with screws 712a, and by adjusting the fixed position of the cleaning element holding part 712 in the prospective direction when fixing the cleaning element holding part 712 to the mounting bracket 5, it is possible to adjust the force with which the outdoor cleaning element 711 held by the cleaning element holding part 712 hits the surface of the outdoor side X1 of the screen 23. Note that in this embodiment, the cleaning element holding part 712 is fixed to the storage frame 21 via the mounting bracket 5, but this is not limiting. For example, the cleaning element holding part 712 may be fixed to the storage frame 21 directly, or may be fixed to the storage frame 21 via a separate member.

[0041] Next, we will explain the storage frame position adjustment mechanism 6 (position adjustment mechanism) of the storage frame 21. 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 front direction according to the position of the exterior wall surface 101a of the outside side X1 of the building skeleton 100 in the front direction.

[0042] Here, as shown in FIGS. 8 to 10, due to the different thicknesses T1, T2, T3 (T3 < T1 < T2) of the exterior wall materials 102a, 102b, 102c, the positions in the expected direction of the outer wall surfaces 101a, 101b, 101c on the outdoor side X1 of the building body 100 are different. As shown in FIG. 2, the distances from the fixed position Xk (see FIG. 2) in the expected direction where the upper frame 111 of the sash frame 11 is fixed by the screw 111a are different positions at different distances as shown in FIGS. 8 to 10 (for example, position Xa (see FIG. 8), position Xb (see FIG. 9), position Xc (see FIG. 10) (in the order from the indoor side X2 to the outdoor side X1, the positions are position Xc, position Xa, position Xb)). As shown in FIGS. 8 and 9, the exterior wall materials 102a, 102b have an exterior wall material main body 102a1, 102b1 and a spacer material 102a2, 102b2.

[0043] As shown in FIG. 2, the upper frame 111 of the sash frame 11 is fixed to the beam member 103 of the building body 100 by a screw 111a at the fixed position Xk in the expected direction at the upper part of the periphery of the opening 100a of the building body 100.

[0044] In the present embodiment, the upper frame 111 of the sash frame 11 is fixed at the same fixed position Xk and is at the same position in the expected direction even when the thicknesses T1, T2, T3 of the exterior wall materials 102a, 102b, 102c are different as shown in FIGS. 8 to 10.

[0045] Conventionally, when attaching the screen device 2 to the sash frame 11, when the thicknesses T1, T2, T3 of the exterior wall materials 102a, 102b, 102c are different, the distances from the storage frame 21 of the screen device 2 to the outer wall surfaces 101a, 101b, 101c on the outdoor side X1 of the building body 100 are different, so it has been difficult to arrange the storage frame 21 in contact with the outer wall surfaces 101a, 101b, 101c on the outdoor side X1 of the building body 100.

[0046] In contrast, in this embodiment, the storage frame position adjustment mechanism 6 can adjust the mounting position of the storage frame 21 in the front direction according to the front direction positions Xa, Xb, and Xc of the exterior wall surfaces 101a, 101b, and 101c on the outside side X1 of the building skeleton 100. As shown in Figures 6 and 8, the storage frame position adjustment mechanism 6 is configured with the 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 in a pair of mounting plates 213 (see Figure 6) provided inside the cover members at the left and right ends of the storage frame 21.

[0047] 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 a predetermined length in the projection direction. As shown in Figures 8 to 10, the shank of the screw 53a is inserted into the guide groove 2131, and when the storage frame 21 is moved in the projection direction, the guide groove 2131 can be moved in the projection direction along the shank of the screw 53a.

[0048] Therefore, even if the prospective positions Xa, Xb, Xc of the exterior wall surfaces 101a, 101b, 101c of the outdoor side X1 of the building structure 100 are different, the guide groove 2131 can be moved in the prospective direction along the shank of the screw 53a by moving the storage frame 21 in the prospective direction according to the prospective positions Xa, Xb, Xc of the exterior wall surfaces 101a, 101b, 101c of the outdoor side X1 of the building structure 100.

[0049] By moving the storage frame 21 in the prospective direction, along the axial portion of the screw 53a, the guide groove 2131 is moved in the prospective direction, and the surface of the indoor side X2 of the storage frame 21 is arranged at a position where it abuts against the outer wall surfaces 101a, 101b, 101c of the outdoor side X1 of the building body 100. Then, in the state where the surface of the indoor side X2 of the storage frame 21 is arranged at a position where it abuts against the outer wall surfaces 101a, 101b, 101c of the outdoor side X1 of the building body 100, the mounting plate 213 and the protruding plate 53 of the mounting fitting 5 are fastened and fixed together by the screw 53a arranged in the guide groove 2131. Thereby, the storage frame 21 can be fixed to the upper frame 111 of the sash frame 11 via the mounting fitting 5 in the state where the surface of the indoor side X2 of the storage frame 21 abuts against the outer wall surfaces 101a, 101b, 101c of the outdoor side X1 of the building body 100. After that, after being fixed by the screw 53a, end cap members 212 are attached to the left and right ends of the storage frame 21 so as to hide the screw 53a as shown in FIG. 6.

[0050] In this way, as shown in FIGS. 8 to 10, even when the prospective positions Xa, Xb, Xc of the outer wall surfaces 101a, 101b, 101c of the outdoor side X1 of the building body 100 are different due to the different thicknesses T1, T2, T3 (T3 < T1 < T2) of the outer wall materials 102a, 102b, 102c, the prospective position of the storage frame 21 is adjusted, and the mounting plate 213 and the protruding plate 53 of the mounting fitting 5 are fastened together by the screw 53a arranged in the guide groove 2131, so that the storage frame 21 can be arranged in contact with the outer wall surfaces 101a, 101b, 101c of the outdoor side X1 of the building body 100.

[0051] Here, the cleaning member holding portion 712 that holds the outdoor side cleaning member 711 is fixed to the outdoor side extending plate 52 of the mounting fitting 5, and the mounting fitting 5 is fixed to the vertical frame 113 of the sash frame 11 via the screen device fixture 4. Therefore, when the prospective position of the storage frame 21 is adjusted by the storage frame position adjusting mechanism 6, the storage frame 21 is moved in the prospective direction with respect to the cleaning member holding portion 712 fixed to the vertical frame 113 of the sash frame 11 via the screen device fixture 4 and the mounting fitting 5.

[0052] The length in the prospective direction of the prospective extension plate 7121 of the cleaning element holding portion 712 is such that the sum of the length in the prospective direction of the prospective extension plate 7121 of the cleaning element holding portion 712 and the length in the prospective direction of the outdoor cleaning element 711 can close the feed-out opening 21a formed in the underside of the storage frame 21 with the prospective direction extension plate 7121 and the outdoor cleaning element 711 in a portion of the feed-out opening 21a of the storage frame 21 that is closer to the outside X1 than the screen 23, even when the position of the storage frame 21 in the prospective direction is adjusted by the storage frame position adjustment mechanism 6 for the storage frame 21. Therefore, when the position in the prospective direction of the storage frame 21 is adjusted by the storage frame position adjustment mechanism 6, the prospective direction extension plate 7121 and the outdoor cleaning element 711 close the portion of the feed-out opening 21a formed in the underside of the storage frame 21 that is closer to the outside X1 than the screen 23, thereby preventing insects from entering the storage frame 21.

[0053] Next, an attachment structure for attaching the screen unit 2 to the sash frame 11 of the window sash 1 using a pair of screen unit attachment fixtures 4 will be described. As shown in Figs. 3 and 4, the screen unit 2 is attached to a pair of vertical frames 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 unit attachment fixtures 4. Furthermore, a pair of guide rails 3 of the screen unit 2 are arranged at both left-right ends of the window sash 1 on the outdoor side X1 of the window sash 1 and extend in the vertical direction. The screen unit attachment fixture 4 and the guide rails 3 are configured with some of their constituent members overlapping.

[0054] As shown in Fig. 4, the pair of screen unit mounting fixtures 4, 4 are arranged apart in the left-right direction, and both left-right ends of the storage frame 21 of the screen unit 2 are fixed to a pair of vertical frames 113, 113. The storage frame 21 of the screen unit 2 is attached to each of the pair of screen unit mounting fixtures 4, 4 by mounting brackets 5. The pair of screen unit mounting fixtures 4, 4 to which the storage frame 21 of the screen unit 2 is attached by the mounting brackets 5 are fixed to the pair of vertical frames 113, 113. The pair of guide rails 3, 3 are arranged at both left-right ends of the screen 23 pulled out from the screen unit 2, respectively.

[0055] Since the pair of screen device mounting fixtures 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, and the configuration of the other side in the left-right direction (the right side in Figure 3) will not be described because it is a symmetrical configuration of the one side (the left side in Figure 3).

[0056] As shown in Fig. 5, the screen device mounting fixture 4 fixes a vertical frame protrusion 115 to a vertical frame 113 of a sash frame 11 of a window sash 1. As shown in Fig. 5, the vertical frame protrusion 115 has a front-side extending plate 115a, an outdoor-side plate portion 115b (plate-shaped portion) connected to the outdoor-side X1 end of the front-side extending plate 115a and extending in the left-right direction (front direction), and a bent plate 115c bent from the outer left-right end of the outdoor-side plate portion 115b to the indoor-side X2. The outdoor-side plate portion 115b is formed in a plate shape extending a predetermined length in the left-right direction (front direction).

[0057] As shown in Figures 4 and 5, the screen device mounting fixture 4 comprises a first fixing member 41 to which the storage frame 21 of the screen device 2 (outdoor fitting) 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 the first fixing member 41 and the second fixing member 42, and a screw 43 (fastening member) that fastens the first fixing member 41 and the second fixing member 42.

[0058] As shown in FIG. 4 , the first fixing member 41 and the second fixing member 42 are disposed on the outer periphery side of the opening of the sash frame 11 in the left-right direction and extend on the outer periphery side of the opening of the sash frame 11 in the up-down direction. The first fixing member 41 and the second fixing member 42 extend in the up-down direction 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 in the up-down direction over an area that includes the entire area in which the screen 23 of the screen unit 2 is pulled out. The first fixing member 41 and the second fixing member 42 are formed, for example, from an extruded shape member made of aluminum material. The first fixing member 41 is also part of the configuration of the guide rail 3. The guide rail 3 includes a guide rail outer component 30 composed of the first fixing member 41 and the guide rail exterior component 31, and an inner rail 32 disposed inside the guide rail outer component 30.

[0059] As shown in FIG. 5 , the first fixing member 41 includes a front-direction extending guide portion 4111 extending in the left-right direction on the indoor side X2, an intermediate protruding portion 4112 protruding from a midpoint in the left-right direction of the front-direction extending guide portion 4111 toward the outdoor side X1, a front-direction extending guide portion 4113 extending from an outer end portion in the left-right direction of the front-direction extending guide portion 4111 toward the outdoor side X1, an indoor-side protruding portion 4114 protruding from the outer end portion in the left-right direction of the front-direction extending guide portion 4111 toward the indoor side X2, and a pull rod connected to the inside in the left-right direction of the end portion on the indoor side X2 of the indoor-side protruding portion 4114. It has a hanging portion 4115, an indoor side facing direction extending portion 4116 extending outward in the left-right direction from the indoor side X2 end of the indoor side protruding portion 4114, an end protrusion portion 4117 protruding outward in the left-right direction from the outdoor side X1 end of the facing direction extending guide portion 4113, an outer extending portion 4118 extending outward in the left-right direction from midway in the facing direction of the facing direction extending guide portion 4113, an outer extending portion 4119 extending from the outer left-right end of the outer extending portion 4118 to the outdoor side X1, and an arc-shaped connecting portion 4120 formed at the outdoor side X1 end of the outer extending portion 4119.

[0060] The hook portion 4115 is arranged by being hooked onto an end portion of the outdoor-side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 opposite to the second fixing member 42 in a state in which the first fixing member 41 and the second fixing member 42 sandwich the outdoor-side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 in the projection direction and the front direction. The hook portion 4115 is formed in a U-shape that opens outward in the left-right direction of the screen unit 2. The hook portion 4115 is formed in a U-shape that is folded back outward in the left-right direction of the screen unit 2 at the inner left-right end portion of a plate member that extends inward in the left-right direction (front direction) from the indoor-side X2 end portion of the indoor-side protruding portion 4114.

[0061] The width in the prospective direction of the U-shaped open space extending in the left-right direction in the hook portion 4115 is formed to be wide enough to insert the outdoor side plate portion 115b (plate portion) of the vertical frame protruding portion 115 of the vertical frame 113. The inner left-right end portion of the outdoor side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 is arranged inside the U-shaped portion of the hook portion 4115. As a result, the inner left-right end portion of the outdoor side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 is hooked onto and arranged on the hook portion 4115.

[0062] The indoor side facing direction extending portion 4116 extends outward in the left-right direction from the plate portion extending in the facing direction of the outdoor side X1 of the U-shape of the hook portion 4115. The indoor side facing direction extending portion 4116 is arranged along the outdoor side X1 surface of the outdoor side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113.

[0063] As shown in FIGS. 2 and 4, the storage frame 21 of the screen unit 2 and the first fixing member 41 of the screen unit attachment fixture 4 are fixed by the mounting bracket 5 at the upper end of the first fixing member 41. At the upper end of the first fixing member 41, as shown in FIG. 6, a vertical extending portion 51 of the mounting bracket 5 is arranged on the outdoor side X1 of the outer extending portion 4118 of the first fixing member 41. The vertical extending portion 51 of the mounting bracket 5 is arranged along the outdoor side X1 surface of the outer extending portion 4118 and is fixed to the outdoor extending portion 4118 of the first fixing member 41 of the screen unit attachment fixture 4 by screws 51a (fastening members). The protruding plate 53 of the mounting bracket 5 is fixed by screws 53a (fastening members) to mounting plates 213 arranged on the left-right end sides of the storage frame 21 of the screen unit attachment fixture 4. As a result, the storage frame 21 of the screen unit attachment fixture 4 is fixed to the first fixing member 41 of the screen unit attachment fixture 4 by the mounting bracket 5.

[0064] 5, the second fixing member 42 is arranged in combination with the first fixing member 41. The second fixing member 42 has a second fixing member facing direction extending portion 4211 extending in the left-right direction between the indoor side facing direction extending portion 4116 and the outdoor side extending portion 4119 of the first fixing member 41, an indoor side extending portion 4212 extending from the outer left-right end of the second fixing member facing direction extending portion 4211 toward the indoor side X2, an inner extending portion 4213 extending inward in the left-right direction from the indoor side X2 end of the indoor side extending portion 4212, a folded-back protruding portion 4214 bending and protruding from the inner left-right end of the inner extending portion 4213 so as to return toward the outdoor side X1, and an outdoor side extending portion 4215 extending from the outer left-right end of the second fixing member facing direction extending portion 4211 toward the outdoor side X1.

[0065] The second fixing member facing direction extending portion 4211 extends in the left-right direction between the indoor facing direction extending portion 4116 and the outer extending portion 4118 of the first fixing member 41, parallel to the indoor facing direction extending portion 4116 and the outer extending portion 4118 of the first fixing member 41.

[0066] The indoor side X2 portion of the indoor side extending portion 4212 is arranged along the outer left-right surface of the curved plate 115c of the vertical frame protruding portion 115 of the vertical frame 113. The inner extending portion 4213 is arranged on the indoor side X2 of the outer left-right portion of the curved plate 115c of the vertical frame protruding portion 115 of the vertical frame 113 and the outdoor side plate portion 115b, and extends inward in the left-right direction from the end of the indoor side X2 of the indoor side extending portion 4212, and extends in the left-right direction to the outer left-right surface of the front-direction extending plate 115a of the vertical frame protruding portion 115 of the vertical frame 113.

[0067] The folded-back protrusion 4214 extends from the inner end of the inner extending portion 4213 in the left-right direction toward the outside side X1 along the outer left-right surface of the projection-direction extending plate 115a of the vertical frame protrusion 115 of the vertical frame 113. The end of the folded-back protrusion 4214 on the outside side X1 abuts against the indoor side X2 surface of the outside plate portion 115b of the vertical frame protrusion 115 of the vertical frame 113.

[0068] As a result, the first fixing member 41 and the second fixing member 42 are arranged to sandwich, in the projection direction and the front direction, the outdoor side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113. With the first fixing member 41 and the second fixing member 42 sandwiching the outdoor side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 in the projection direction and the front direction, the hook portion 4115 is arranged to hook onto the inner end portion in the left-right direction of the outdoor side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113.

[0069] The screws 43 fasten the first fixing member 41 and the second fixing member 42 together in a state in which the first fixing member 41 and the second fixing member 42 sandwich the outdoor side plate portion 115b of the vertical frame protrusion 115 of the vertical frame 113 in the forward and backward directions. As shown in Fig. 4, a plurality of screws 43 are provided at positions spaced apart in the vertical direction on the first fixing member 41 and the second fixing member 42, and secure the first fixing member 41 and the second fixing member 42 together.

[0070] As shown in Figure 5, the screw 43 is formed to extend in the projection direction, and by moving it from the outside side X1 to the inside side X2, it is inserted into the outer extension portion 4118 of the first fixing member 41 and the second fixing member projection direction extension portion 4211 of the second fixing member 42, and is threadedly engaged with the outer extension portion 4119 of the first fixing member 41 and the second fixing member projection direction extension portion 4211 of the second fixing member 42. With the tip of the screw 43 abutting the outdoor side X1 surface of the indoor side facing extension portion 4116 of the first fixing member 41, the screw 43 is rotated so that the thread groove of the shank of the screw 43 pulls the second fixing member facing extension portion 4211 of the second fixing member 42 toward the outdoor side X1, thereby moving the second fixing member 42 to the outdoor side X1, and the outdoor side plate portion 115b of the vertical frame protrusion portion 115 of the vertical frame 113 is clamped and fixed between the outdoor side X1 end of the folded protrusion portion 4214 of the second fixing member 42 and the indoor side facing extension portion 4116 of the first fixing member 41. As a result, the outdoor panel portion 115b of the vertical frame protrusion 115 of the vertical frame 113 is sandwiched in the projection direction between the outdoor X1 end of the folded protrusion 4214 of the second fixing member 42 and the indoor projection direction extending portion 4116 of the first fixing member 41, and is fixed in a state where movement in the projection direction is restricted.

[0071] Furthermore, in the left-right direction (visible direction), the inside left-right end of the outdoor-side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 is hooked by the hook portion 4115, restricting inward movement in the left-right direction, and the outside left-right end is restricted from outward movement in the left-right direction by the inside left-right surface of the indoor-side extending portion 4212 of the second fixing member 42. As a result, the outdoor-side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 is disposed between the hook portion 4115 of the first fixing member 41 and the indoor-side extending portion 4212 of the second fixing member 42, and is fixed in a state where movement in the visible direction is restricted.

[0072] The mounting structure of the guide rail 3 will be described. As shown in Fig. 5, the guide rail 3 comprises a guide rail outer constituent part 30 (outer constituent part) composed of a first fixing member 41 (outer main body part) and a guide rail outdoor member 31 (guide rail cover part), and an inner rail 32 arranged inside the guide rail outer constituent part 30. The first fixing member 41 constitutes the indoor side X2 part and the outer side parts in the left-right direction of the guide rail 3. The first fixing member 41 is arranged exposed to the outside of the indoor side X2 of the guide rail 3. The guide rail outdoor member 31, which constitutes the outdoor side X1 part of the guide rail 3, is attached to the outdoor side X1 of the first fixing member 41.

[0073] As shown in Fig. 5 , the guide rail outdoor member 31 has an outdoor-guide-member horizontal extending portion 311 extending in the horizontal direction, an intermediate protruding portion 312 protruding toward the indoor side X2 from a horizontal midpoint of the outdoor-guide-member horizontal extending portion 311, an engaging protruding portion 313 protruding toward the indoor side X2 from a horizontally outer portion of the outdoor-guide-member horizontal extending portion 311 at a horizontal midpoint, the intermediate protruding portion 312, and an arc-shaped locking portion 314 protruding toward the indoor side X2 from an outer end of the outdoor-guide-member horizontal extending portion 311. An end protrusion 4117 of the first fixing member 41 engages with a base portion of the engaging protruding portion 313. An arc-shaped connecting portion 4120 of the first fixing member 41 is rotatably connected to and locked with the arc-shaped locking portion 314. As a result, the guide rail exterior member 31 is rotatably connected to the first fixed member 41, as shown in Figure 11, and can open the inside of the first fixed member 41 by rotating relative to the first fixed member 41.

[0074] 2, in order to prevent the guide rail outer component 30 from sliding off, a cap 33 is provided at the lower end of the guide rail 3. The cap 33 includes a bottom plate 331 and an attachment piece 332 that protrudes upward from the upper surface of the bottom plate 331. The attachment piece 332 is fixed to the lower end of the guide rail 3 with a screw 332a, thereby fixing the cap 33 to the lower end of the guide rail 3.

[0075] 5, the inner rail 32 is disposed inside the guide rail outer component 30 in a state in which its inward movement in the left-right direction is restricted by the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the guide rail outer component 31. The inner rail 32 guides the screen 23 to be movable up and down in the pull-out direction, while engaging the edge member 231 disposed at the end of the screen 23 in a direction perpendicular to the pull-out direction.

[0076] As shown in FIG. 5, the inner rail 32 has a hollow frame portion 323 and a pair of protrusions 324 (regulating protrusions) that protrude toward the outdoor side X1 and the indoor side X2 at the outer left-right ends of the hollow frame portion 323.

[0077] The hollow frame portion 323 is disposed 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 therein and a communicating groove portion 322 that connects the inside and outside of the hollow portion 321. The edge member 231 disposed at the end of the screen 23 in a direction perpendicular to the pull-out direction is engaged with the inner rail 32 and guided by the guide rail 3, with the edge member 231 disposed in the hollow portion 321 of the hollow frame portion 323 and the portions on the left and right end sides of the screen 23 (ends in a direction perpendicular to the pull-out direction) passing through the communicating groove portion 322. The hollow portion 321 inside the hollow frame portion 323 constitutes the guide groove 32a of the inner rail 32.

[0078] The pair of protrusions 324 have an outdoor protrusion plate 324a that protrudes toward the outdoor side X1 in the indoor / outdoor direction (forward direction) outside the left and right of the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the guide rail outdoor side member 31 so as to overlap with the intermediate protrusion 312 of the guide rail outdoor side member 31 when viewed in the left and right direction, and an indoor protrusion plate 324b that protrudes toward the indoor side X2 in the indoor / outdoor direction (forward direction) so as to overlap with the intermediate protrusion 4112 of the first fixing member 41 when viewed in the left and right direction.

[0079] The pair of protrusions 324 are restricted from moving inward in the left-right direction by the intermediate protrusions 4112 of the first fixing member 41 in the guide rail outer component 30 and the intermediate protrusions 312 of the guide rail outer component 31. As a result, the inner rail 32 is arranged inside the guide rail outer component 30 with the pair of protrusions 324 restricted from moving inward in the left-right direction relative to the guide rail outer component 30 by the intermediate protrusions 4112 of the first fixing member 41 and the intermediate protrusions 312 of the guide rail outer component 31.

[0080] When the inner rail 32 is disposed inside the guide rail 3, the arc-shaped locking portion 314 of the guide rail exterior member 31 is rotatably connected to the arc-shaped connecting portion 4120 of the first fixing member 41, so that the guide rail exterior member 31 can be rotated around the arc-shaped locking portion 314. As a result, in the guide rail outer component 30, as shown in Fig. 5, the guide rail exterior member 31 can be rotated from a closed state to an open state by disengaging the end protrusion 4117 of the first fixing member 41 engaged with the base portion of the engaging protrusion 313, and then rotating the guide rail exterior member 31 around the arc-shaped locking portion 314, as shown in Fig. 11.

[0081] Then, by exposing the outside-room side X1 of the inside of the guide rail outside component 30, it is possible to open the inside of the guide rail outside component 30. As a result, even if, for example, an edge member 231 arranged at an end of the screen 23 in a direction perpendicular to the pull-out direction becomes pinched between the inner rail 32, the inner rail 32 can be exposed to the outside-room side X1 by rotating the guide rail outside component 31 about the arc-shaped locking portion 314, and therefore, the pinched state of the edge member 231 of the screen 23 can be easily resolved by removing the inner rail 32 without disassembling the screen unit 2.

[0082] By rotating the guide rail exterior member 31 around the arc-shaped locking portion 314, the inner rail 32 is exposed to the exterior side X1, and the inner rail 32 is removed to release the pinched screen 23. After that, the guide rail exterior member 31 can be rotated around the arc-shaped locking portion 314 from an open state in the guide rail exterior component 30 as shown in Fig. 11 to a closed state as shown in Fig. 5. Then, the end protrusion 4117 of the first fixing member 41 can be engaged with the base portion of the engaging protrusion 313, thereby easily attaching the guide rail exterior member 31 to the first fixing member 41.

[0083] Here, when the guide rail exterior member 31 is rotated into the closed state, the intermediate protrusions 312 of the guide rail exterior member 31 are positioned inside the exterior protrusion plates 324a of the inner rail 32 in the left-right direction, so the guide rail exterior member 31 can be easily attached to the first fixing member 41 in a state where the inward movement of the exterior protrusion plates 324a of the inner rail 32 in the left-right direction is restricted. Furthermore, the intermediate protrusions 4112 of the first fixing member 41 and the intermediate protrusions 312 of the guide rail exterior member 31 restrict the inward movement of the pair of protrusions 324 of the inner rail 32 in the left-right direction, so the guide rail exterior member 31 can be attached to the first fixing member 41 in a state where the inner rail 32 is unlikely to come off the guide rail exterior component 30.

[0084] When fixing the screen unit 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 skeleton 100, a pair of screen unit mounting fixtures 4, 4 are fixed to a pair of vertical frames 113, 113 of the sash frame 11, as shown in Figures 4 and 5. Specifically, as shown in Figure 5, with the outdoor side panel portion 115b of the vertical frame 113 sandwiched between a first fixing member 41 and a second fixing member 42, the first fixing member 41 and the second fixing member 42 are fastened and fixed with screws 43.

[0085] 2 and 6, the vertically extending portion 51 of the mounting bracket 5 fixed to the storage frame 21 of the screen unit 2 is fixed to the first fixing member 41 of the screen unit fixture 4. Then, the guide rail exterior member 31 is attached to the exterior side X1 of the first fixing member 41. This makes it possible to easily attach the screen unit 2 to the sash frame 11 using the screen unit fixture 4 in a manner that is less likely to cause misalignment in the left-right direction (view direction) and the view direction.

[0086] According to this embodiment, the following effects are achieved. The screen unit 2 of this embodiment includes a storage frame 21, a screen 23, and guide rails 3 that guide both ends of the screen 23 in a direction perpendicular to the pull-out direction. The screen 23 has a pair of edge members 231 that are provided at both ends of the screen 23 in a direction perpendicular to the pull-out direction and are guided by the guide rails 3 while being engaged with the guide rails 3 inside the guide rails 3. The guide rails 3 include a guide rail outer component 30. The guide rail outer component 30 has a first fixing member 41 and a guide rail outer component 31 that is rotatably connected to the first fixing member 41 and can open the interior of the first fixing member 41 by rotating the guide rail outer component 31. As a result, even if the edge member 231 of the screen 23 is caught in the guide rails 3, the state in which the edge member 231 of the screen 23 is caught in the guide rails 3 can be easily resolved without disassembling the screen unit 2 by rotating the guide rail outer component 31 to open the interior of the first fixing member 41.

[0087] Furthermore, in this embodiment, the guide rail 3 includes an inner rail 32 disposed inside the guide rail outer component 30, and the inner rail 32 guides the screen 23 movably in the pull-out direction while engaging an edge member 231 of the screen 23. As a result, even if the edge member 231 disposed at the end of the screen 23 in a direction perpendicular to the pull-out direction is pinched between the inner rail 32, the guide rail outer component 31 can be rotated to expose the inner rail 32 to the outside X1, and therefore, the pinched state of the edge member 231 of the screen 23 can be easily resolved by removing the inner rail 32 without disassembling the screen unit 2.

[0088] Furthermore, in this embodiment, the inner rail 32 has a hollow portion 321 and a communicating groove portion 322 that communicates the inside and outside of the hollow portion 321, and the edge member 231 is engaged with the inner rail 32 and guided by the guide rail 3 in a state in which the edge member 231 is disposed in the hollow portion 321 and the screen 23 is passed through the communicating groove portion 322. As a result, the edge member 231 provided at the end of the screen 23 is engaged with the inner rail 32 and guided along the guide rail 3, making it possible to prevent the screen 23 from slipping off the guide rail 3.

[0089] In this embodiment, the inner rail 32 has a protrusion 324 that protrudes in the projection direction. Lateral movement of the protrusion 324 is restricted by the guide rail outer component 30. As a result, when the guide rail outdoor component 31 is rotated to the closed position, the intermediate protrusion 312 of the guide rail outdoor component 31 is positioned inside the outer protrusion plate 324a of the inner rail 32 in the lateral direction. Therefore, the guide rail outdoor component 31 can be easily attached to the first fixing member 41 while the inward movement of the outer protrusion plate 324a of the inner rail 32 is restricted. Furthermore, the intermediate protrusion 4112 of the first fixing member 41 and the intermediate protrusion 312 of the guide rail outdoor component 31 restrict the inward movement of the pair of protrusions 324 of the inner rail 32 in the lateral direction. Therefore, the guide rail outdoor component 31 can be attached to the first fixing member 41 while the inner rail 32 is unlikely to come off the guide rail outer component 30.

[0090] Next, a second embodiment will be described. As shown in Fig. 12, in addition to the configuration of the first embodiment shown in Fig. 8, the second embodiment further includes an indoor cleaning member 721 (second cleaning member) at the feed-out opening 21a (screen feed-out portion) formed on the underside of the storage frame 21 of the screen unit 2. The indoor cleaning member 721 is arranged on the indoor side X2 of the screen 23 at the feed-out opening 21a of the storage frame 21. The indoor cleaning member 721 is made of, for example, mohair. The tip portion of the indoor cleaning member 721 is arranged so as to abut against 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 a cleaning member holding portion 722.

[0091] 12, the cleaning element holding portion 722 has a front-direction extending plate 7221 extending in the vertical direction, a hook 7222 that is provided on the indoor side X2 of the lower end of the front-direction extending plate 7221 and opens upward, an outdoor side protruding portion 7223 that protrudes from the upper end of the front-direction extending plate 7221 toward the outdoor side X1, and a cleaning element attachment groove 7224 (holding groove) that is arranged at the outdoor side X1 end of the outdoor side protruding portion 7223.

[0092] The facing direction extension plate 7221 is arranged along the outdoor X1 surface of the outdoor 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 X1 surface of the outdoor end downward extension plate 1111 of the upper frame 111 with screws 722a.

[0093] The lower end of the outdoor-side end downward extension plate 1111 of the upper frame 111 of the sash frame 11 is placed in the portion of the hook piece 7222 that opens upward. As a result, the hook piece 7222 is hooked onto the lower end of the outdoor-side end downward extension plate 1111 of the upper frame 111 of the sash frame 11.

[0094] The cleaning element mounting groove 7224 has a C-shaped cross section that opens toward the outside side X1, and extends in the left-right direction over the entire longitudinal length of the cleaning element holding portion 722. The cleaning element mounting groove 7224 holds the indoor cleaning element 721. The indoor cleaning element 721 is removably mounted in the cleaning element mounting groove 7224.

[0095] The indoor cleaning member 721 has a mounting plate 7211 attached to the cleaning member mounting groove 7224, and a cleaning part 7212 protruding from the mounting plate 7211 toward the outdoor side X1. The cleaning part 7212 is made of mohair, for example. The indoor cleaning member 721 can be attached to and detached from the cleaning member holding part 722 by sliding the mounting plate 7211 left and right along the cleaning member mounting groove 7224.

[0096] 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, so that both the outdoor surface X1 and the indoor surface X2 of the screen 23 can be easily cleaned simultaneously.
