Description

[Technical Field]

[0001] The present disclosure relates to an outdoor building fixture and a mounting structure for an outdoor building fixture. [Background technology]

[0002] Conventionally, an outdoor fitting fixture has been known in which a sash frame is clamped in the forward direction between a first fixing member and a second fixing member, and the first fixing member and the second fixing member are fixed with a fastener, and an outdoor fitting (e.g., a screen device) is fixed to the sash frame (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-214568 Summary of the Invention [Problem to be solved by the invention]

[0004] The outdoor fitting fixture described in Patent Document 1 sandwiches the sash frame between the first fixing member and the second fixing member in the front direction, and in the front direction, a return piece provided on the sash frame that restricts movement in the front direction restricts positional deviation of the sash frame in the front direction. If the sash frame is configured without a return piece that restricts movement in the front direction, when the screws loosen, the sash frame may move in the front direction, causing the first fixing member and the second fixing member to come off the sash frame. Therefore, there is a demand for an outdoor fitting fixture that is less likely to come off the sash frame.

[0005] The present disclosure aims to provide an outdoor fitting and a fitting structure for outdoor fittings that are less likely to come off a sash frame. [Means for solving the problem]

[0006] The present disclosure relates to an outdoor fitting fixture that fixes an outdoor fitting to the outside of a sash frame, comprising: a first fixing member to which the outdoor fitting is fixed; a second fixing member that is combined with the first fixing member; and a fastening member that fastens the first fixing member and the second fixing member together when the sash frame is sandwiched between the first fixing member and the second fixing member in the forward and backward directions, wherein the first fixing member has a hook portion that is positioned to hook onto the end of the sash frame opposite the second fixing member when the sash frame is sandwiched between the first fixing member and the second fixing member in the forward and backward directions.

[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 the screen unit 2 (outdoor fitting) of this embodiment will be described. As shown in Figs. 1 to 3, the screen unit 2 is mounted on the 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 the 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 section 22 (see Fig. 2) stored in the storage frame 21, a screen 23 that can be wound around 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, and a pair of guide rails 3, 3 (guide sections) on the left and right.

[0013] 3 and 4, 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 a screen unit attachment fixture 4. The attachment structure of the screen unit 2 will be described in detail later.

[0014] 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 arranged above the outdoor side X1 of the upper frame 111 of the sash frame 11. The back surface (the indoor side X2 surface) of the storage frame 21 is arranged in contact with the exterior wall surface 101 of the outdoor side X1 above 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, a feeding opening 21a that opens downward and extends in the left-right direction is formed on the bottom surface of the storage frame 21.

[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] 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.

[0019] 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.

[0020] 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.

[0021] 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.

[0022] 5, edge members 231 are attached to both left and right ends of the screen 23. The pair of edge members 231 provided at both left and right ends of the screen 23 are arranged to be slidable in the up and 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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).

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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).

[0036] 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).

[0037] 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.

[0038] 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.

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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] The mounting structure of the guide rail 3 will now be described. As shown in Fig. 5, the guide rail 3 is configured to include a first fixing member 41 and a guide rail exterior member 31. The first fixing member 41 forms the interior side X2 portion and the outer side in the left-right direction of the guide rail 3. The guide rail exterior member 31, which forms the exterior side X1 portion of the guide rail 3, is attached to the exterior side X1 of the first fixing member 41.

[0053] 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 locked to the arc-shaped locking portion 314.

[0054] 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. Specifically, as shown in Fig. 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.

[0055] 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.

[0056] According to this embodiment, the following effects are achieved: The screen unit mounting fixture 4 of this embodiment fixes the screen unit 2 to the exterior side X1 of the sash frame 11, and includes a first fixing member 41 to which the screen unit 2 is fixed, a second fixing member 42 combined with the first fixing member 41, and a screw 43 that fastens the first fixing member 41 and the second fixing member 42 in a state in which the vertical frame 113 of the sash frame 11 is sandwiched between the first fixing member 41 and the second fixing member 42 in the projection direction and the front direction, and the first fixing member 41 has a hook portion 4115 that is positioned to be hooked onto the end of the vertical frame 113 of the sash frame 11 on the side opposite to the second fixing member 42 in a state in which the vertical frame 113 of the sash frame 11 is sandwiched between the first fixing member 41 and the second fixing member 42 in the projection direction and the front direction.

[0057] As a result, with the first fixing member 41 and the second fixing member 42 sandwiching the outdoor-side plate portion 115b of the vertical frame protrusion 115 of the vertical frame 113 of the sash frame 11 in the projection direction and the front direction, the hook portion 4115 is positioned to hook onto the end of the vertical frame 113 of the sash frame 11 on the side opposite to the second fixing member 42, thereby suppressing misalignment of the vertical frame 113 of the sash frame 11 in the projection direction and the front direction, making it difficult for the first fixing member 41 and the second fixing member 42 to come off from the vertical frame 113 of the sash frame 11. Therefore, even if the screws loosen, the outdoor-side plate portion 115b of the vertical frame protrusion 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 a state where misalignment of the vertical frame 113 of the sash frame 11 in the projection direction and the front direction of the sash frame 11 is suppressed.

[0058] Furthermore, in this embodiment, the hook portion 4115 is formed in a U-shape by extending the indoor-side facing-direction extending portion 4116 inward in the left-right direction and folding back the end of the plate material extending in the left-right direction. This makes it easy to hook the outdoor-side plate portion 115b of the vertical frame protruding portion 115 of the vertical frame 113 onto the hook portion 4115, and the hook portion 4115 easily hooks onto the end of the vertical frame 113 of the sash frame 11 on the side opposite to the second fixing member 42. Therefore, even if the screws are loosened, the first fixing member 41 and the second fixing member 42 are even less likely to come off the vertical frame 113 of the sash frame 11.

[0059] Furthermore, in this embodiment, the first fixing member 41 and the second fixing member 42 are arranged more outer circumferentially than the opening of the sash frame 11 in the left-right direction, and are formed so as to extend more outer circumferentially than the opening of the sash frame 11 in the up-down direction. As a result, the first fixing member 41 and the second fixing member 42 are arranged more outer circumferentially than the opening of the sash frame 11 in the left-right direction and are formed so as to extend more outer circumferentially than the opening of the sash frame 11 in the up-down direction, and the vertical frame 113 of the sash frame 11 is fixed by the first fixing member 41 and the second fixing member 42 over a long range in the up-down direction, so that even if the screws are loosened, the first fixing member 41 and the second fixing member 42 are even less likely to come off the vertical frame 113 of the sash frame 11.

[0060] Furthermore, in the present embodiment, the vertical frame 113 has a plate-shaped outdoor-side plate portion 115b extending a predetermined length in the front direction, the first fixing member 41 and the second fixing member 42 are arranged to sandwich the outdoor-side plate portion 115b of the vertical frame 113 in the front direction and the front direction, and the hook portion 4115 is arranged to hook an end portion of the outdoor-side plate portion 115b of the vertical frame 113 in the front direction. In this way, by sandwiching the outdoor-side plate portion 115b of the plate-shaped vertical frame 113 between the first fixing member 41 and the second fixing member 42 and hooking an end portion of the outdoor-side plate portion 115b of the vertical frame 113 of the sash frame 11 in the front direction, a configuration can be achieved in which the first fixing member 41 and the second fixing member 42 are even less likely to come off the vertical frame 113 of the sash frame 11 even if the screws are loosened.
