[0012] As shown in Figures 4 and 5, a mohair 6 as a first insect-proofing component and a screen door fall prevention component 7 are provided in the first gap between the upper screen door rail 215 and the upper outer screen door rail 214 between the upper frame 21 and the outer sash 3.

[0013] The mohair 6 is composed of a plurality of hairs extending downward, with the length in the prospective direction being the same as the length of the first gap in the prospective direction, and the length in the left-right direction being formed to be approximately the same as the length of the outer calling frame 34 of the outer shutter 3 in the left-right direction. The mohair 6 is fixed to the center in the left-right direction of the upper frame body 211 of the upper frame 21 with double-sided tape. Note that the mohair 6 may be fixed by a configuration other than double-sided tape such as an adhesive.

[0014] The screen door fall prevention part 7 connects the frame body 2 and the screen door 5 so that the screen door 5 does not fall from the frame body 2. As shown in FIGS. 4, 5, and 6, the screen door fall prevention part 7 includes a metal linear member 71 and a fall prevention member 72 respectively. Mounting members 711 are respectively fixed to both ends of the linear member 71. The linear member 71 is fixed to the upper frame body 211 in a state separated from the upper frame body 211 and passing through between the hairs of the mohair 6 by a screw 712 passing through the mounting member 711 and the upper frame body 211 from below, and a back plate 713 disposed on the upper side of both ends in the left-right direction of the upper frame body 211 and screwed to the screw 712. The back plate 713 is fixed to the upper frame body 211 by a screw 714 passing through the upper frame body 211 and screwed to the back plate 713 on the outer side in the left-right direction of each screw 712. The fall prevention member 72 includes a cylindrical portion 721 through which the linear member 71 is inserted, a first extension portion 722 extending downward from the cylindrical portion 721, a second extension portion 723 extending outward from the lower end of the first extension portion 722 to the outdoor side, and a fixing portion 724 extending downward from the outdoor side end portion of the second extension portion 723. The fixing portion 724 is fixed to the center in the left-right direction of the finding surface on the indoor side of the screen door upper frame body 511 in a state where the first extension portion 722 and the second extension portion 723 are in contact with the upper guide member 511A by a screw 725 passing through the fixing portion 724 and the screen door upper frame 511 from the indoor side, and a back plate 726 disposed in the screen door upper frame 511 and screwed to the screw 725. In the screen door fall prevention part 7 configured as described above, when the screen door 5 is opened and closed, the fall prevention member 72 slides with respect to the linear member 71 and passes through between the hairs of the mohair 6.

[0015] A second insect-proof component 8 made of a soft resin is provided in a second gap between an upper outer障子 rail 214 and a central protruding piece 213 between an upper frame 21 and an outer障子 3. Hereinafter, the configuration of the second insect-proof component 8 will be described based on the state in which the second insect-proof component 8 is provided in the second gap.

[0016] As shown in FIG. 7, the second insect-proof component 8 includes a rectangular plate-shaped base portion 81 whose length in the left-right direction is longer than its length in the prospective direction. The length of the base portion 81 in the prospective direction is slightly shorter than the length of the second gap in the prospective direction, and the length of the base portion 81 in the left-right direction is longer than the lengths of the outer召合せ frame 34 of the outer障子 3 and the mohair 6 in the left-right direction. A pair of screw holes 811 penetrating the base portion 81 in the thickness direction are provided in the base portion 81. The screw holes 811 are provided at the center in the prospective direction of the base portion 81 and at both left and right ends.

[0017] An indoor-side extension portion 82 is provided on the lower surface of the base portion 81. The indoor-side extension portion 82 is provided so as to extend downward from the indoor-side side edge of the base portion 81. Five fin portions 83 arranged at substantially equal intervals in the left-right direction are provided on the lower surface of the base portion 81. Two fin portions 83 are provided at both left and right ends. Each fin portion 83 includes four fin pieces 831 that become thinner toward the lower end. The four fin pieces 831 are provided so as to be arranged in the prospective direction in a state where their thickness directions are parallel to the left-right direction, and are configured to be able to bend in the left-right direction.

[0018] A pair of positioning portions 84 are provided on the upper surface of the base portion 81. Each positioning portion 84 is provided so as to be located at both left and right ends on the outdoor side of the base portion 81. Each positioning portion 84 includes an outer surface 841 located at both left and right ends of the base portion 81 and a positioning surface 842 located on the central side in the left-right direction of the base portion 81 when viewed from above. Each outer surface 841 and each positioning surface 842 are formed in a planar shape orthogonal to the upper surface of the base portion 81 and parallel to each other. A pair of fitting and fixing portions 85 are provided on the upper surface of the base portion 81. Each fitting and fixing portion 85 is formed at approximately the same height as the positioning portion 84 and is arranged side by side in the left-right direction between the pair of positioning portions 84. Each fitting and fixing portion 85 comprises a fitting base portion 851 configured to bend in the depth direction and a fitting claw portion 852 that protrudes from the outdoor-facing and upper end of the fitting base portion 851. Each fitting claw portion 852 is provided with an inclined surface 852A such that its upper end is located on the indoor side of its lower end.

[0019] Next, we will describe the mounting structure of the second insect-repellent component 8. As shown in Figure 8, the upper frame body 211 to which the second insect-proof component 8 is attached is provided with a fixing dovetail groove 211A, a pair of positioning grooves 211B adjacent to the left and right sides of the fixing dovetail groove 211A, and a pair of end dovetail grooves 211C adjacent to the left and right outer sides of each positioning groove 211B. The fixing dovetail groove 211A is provided above the outer meeting stile 34 when the outer sash 3 is closed. The fixing dovetail groove 211A, each positioning groove 211B, and each end dovetail groove 211C are provided so as to be continuous in the left and right direction on the indoor side of the connection portion between the upper frame body 211 and the upper outer sash rail 214. Each positioning groove 211B is recessed upward and is composed of a groove 211D whose length in the depth direction of the opening is the same as the length in the depth direction of the bottom. The fixing dovetail groove 211A and each end-side dovetail groove 211C are composed of a groove 211D and a pair of opposing protrusions 211E that protrude toward each other from the opposing open ends of the groove 211D. The length in the left-right direction of each opposing projection 211E constituting the fixing dovetail groove 211A is approximately the same as the length between the pair of positioning parts 84 constituting the second insect-proof component 8. The length between the pair of opposing projections 211E is longer than the length in the depth direction of the fitting base 851 of the fitting fixing part 85 constituting the second insect-proof component 8, and is less than the combined maximum length in the depth direction of the fitting base 851 and the fitting claw part 852. The length of the positioning groove 211B in the depth direction, that is, the length of the groove 211D in the depth direction, is greater than or equal to the length of each positioning part 84 in the depth direction. The length of the positioning groove 211B in the left-right direction is greater than or equal to the length of each positioning part 84 in the left-right direction.

[0020] The fixing dovetail groove 211A, positioning groove 211B, and end dovetail groove 211C are formed, for example, as follows. First, an upper frame 21 is prepared, on which a dovetail groove, composed of a groove 211D and a pair of opposing protrusions 211E, is provided throughout the left-right direction. The fixing dovetail groove 211A, positioning groove 211B, and end dovetail groove 211C can be formed by cutting out the portion of the opposing protrusions 211E of the dovetail groove that corresponds to the positioning groove 211B. Note that the length of the groove 211D in the depth direction of the opening may be longer than the length of the bottom in the depth direction.

[0021] When attaching the second insect-proof component 8 to the upper frame 21, first, with the pair of positioning parts 84 positioned below each positioning groove 211B and the pair of fitting and fixing parts 85 positioned below the fixing dovetail groove 211A, the second insect-proof component 8 is raised, and the pair of positioning parts 84 are inserted into each positioning groove 211B, while the inclined surfaces 852A of the fitting claws 852 of each fitting and fixing part 85 come into contact with the opposing projections 211E on the outdoor side. When the second insect-proof component 8 is raised further from this state, the fitting base 851 bends inward as the inclined surfaces 852A slide against the opposing projections 211E, and when the entire fitting claw 852 moves above the opposing projections 211E, the fitting base 851 returns to its original shape, and the fitting claws 852 are locked into the opposing projections 211E. This locking mechanism secures the second insect-proof component 8 to the upper frame 21. Furthermore, the contact between the left and right edges of each opposing projection 211E and the positioning surfaces 842 of each positioning portion 84 positions the second insect-proof component 8 in the left-right direction relative to the upper frame 21. Finally, the second insect-proof component 8 is secured to the upper frame 21 by screwing screws 86, inserted from below into each screw hole 811 of the second insect-proof component 8, into the upper frame body 211.

[0022] In the sliding window 1 having the above configuration, when the outer sash 3 shown in Figure 2 is closed, the mohair 6 hairs that are located above the upper guide member 511A and the outer meeting stile 34 of the screen door 5 bend when their tips come into contact with the upper guide member 511A, the outer meeting stile 34, or the exterior guide member 311. Of the fin pieces 831 of the second insect-proof component 8, at least a portion of which are located above the interior guide member 311 of the outer meeting stile 34 bends in the left-right direction when their tips come into contact with the guide member 311. Of the fin pieces 831 of the second insect-proof component 8 that are located above the outer meeting stile 34 but not above the interior guide member 311, a small gap is formed between the outer meeting stile 34 and the fin piece 831 of the second insect-proof component 8. When the outer shoji screen 3 shown in Figure 3 is open and the screen door 5 is closed, the mohair 6 and the second insect-proof component 8 are in a state where the "outer meeting stile 34" in the above-mentioned description of the state when the outer shoji screen 3 is closed is replaced with the "outer door frame 33". The mohair 6 and the second insect-proof component 8, positioned in these manner, prevent insects from entering the room when the outer shoji screen 3 is closed, or when the outer shoji screen 3 is open and the screen door 5 is closed.

[0023] According to the above embodiment, the wind resistance of the outer sash 3 can be improved by guiding the outer sash 3 to slide freely on the upper outer sash rail 214 of the frame 2. Furthermore, insect resistance can be improved by placing mohair 6 in the first gap and the second insect-repellent component 8 in the second gap.

[0024] As the first insect-repellent component, mohair 6 is used. Therefore, when the screen door 5 is slid, the fall prevention member 72 can move to the right and left sides of the mohair 6 without its sliding being hindered by the mohair 6. Thus, wind resistance and insect protection can be improved, and the screen door 5 can be prevented from falling.

[0025] The configuration for fixing the second insect-proof component 8 to the upper frame 21 utilizes a fixing dovetail groove 211A provided on the upper frame 21 and a fitting fixing portion 85 provided on the second insect-proof component 8. Therefore, the second insect-proof component 8 can be fixed to the upper frame 21 by a simple method of fitting the fitting fixing portion 85 into the fixing dovetail groove portion 211A.

[0026] As a configuration for positioning the second insect-proof component 8 in the left-right direction relative to the upper frame 21, a positioning groove 211B provided adjacent to the fixing dovetail groove 211A in the upper frame 21 and a positioning portion 84 provided on the second insect-proof component 8 are applied. Therefore, the second insect-proof component 8 can be positioned in the left-right direction relative to the upper frame 21 by simply inserting the positioning portion 84 into the positioning groove portion 211B and bringing the positioning surface 842 into contact with the fixing dovetail groove portion 211A.

[0027] [Differentiation] As shown in Figure 9, instead of the mohair 6, a first insect-proof component 9 made of soft resin is provided in the first gap, and the screen door fall prevention part 7 does not need to be provided. The configuration of the first insect-proof component 9 will be described below based on the state in which the first insect-proof component 9 is provided in the first gap. The first insect-repellent component 9 comprises a rectangular plate-shaped base 91 whose planar shape is substantially the same as the planar shape of the mohair 6. The base 91 is provided with a pair of screw holes (not shown) that penetrate the base 91 in the thickness direction. The screw holes are provided so as to be aligned left and right in the center of the base 91 in the depth direction. Five fin portions 93 are provided on the lower surface of the base 91, arranged at substantially equal intervals in the left-right direction. Two fin portions 93 are provided at both the left and right ends. Each fin portion 93 comprises three fin pieces 931 that become thinner towards the lower end. The three fin pieces 931 are provided so as to be aligned in the depth direction with their thickness direction parallel to the left-right direction, and are configured to bend in the left-right direction. The first insect-proof component 9 is fixed to the upper frame body 211 by screwing screws (not shown), which are inserted from below into each screw hole, into the upper frame body 211. The first insect-proof component 9 may also be fixed in the same manner as the fitting and fixing portion 85 of the second insect-proof component 8, or it may be fixed by means of a method other than screws, such as double-sided tape or adhesive.

[0028] In the sliding window 1 having the first insect-proof component 9 and the second insect-proof component 8 described above, when the outer sash 3 is closed, at least a portion of the fin pieces 931 of the first insect-proof component 9 that are located above the outdoor-side guide member 311 of the outer meeting stile 34 will bend in the left-right direction with their tips contacting the guide member 311. A small gap is formed between the fin pieces 931 of the first insect-proof component 9 that are located above the outer meeting stile 34 but not above the outdoor-side guide member 311 and the outer meeting stile 34. A small gap is formed between the fin pieces 931 of the first insect-proof component 9 that are located above the upper guide member 511A of the screen door 5 and the upper guide member 511A. The second insect-proof component 8 is in the state described in the above embodiment. When the outer shoji screen 3 is open and the screen door 5 is closed, the first insect-proof component 9 and the second insect-proof component 8 are in the state described above when the outer shoji screen 3 is closed, with "outer meeting stile 34" replaced by "outer door frame 33". The first insect-proof component 9 and the second insect-proof component 8, positioned in these manner, prevent insects from entering the room when the outer sliding door 3 is closed, or when the outer sliding door 3 is open and the screen door 5 is closed.

[0029] The second insect-proof component 8 may be provided with one or more fitting and fixing parts 85. When fixing the second insect-proof component 8 to the upper frame 21, the fitting and fixing parts 85 may be used alone without providing screw holes 811, or the fitting and fixing parts 85 may be used alone with screws inserted through screw holes 811, or double-sided tape or adhesive may be used instead of the fitting and fixing parts 85 and screws. The second insect-repellent component 8 does not need to have a positioning section 84, or it may have only one positioning section 84. In this example, the groove 211D of the dovetail groove was used as the positioning groove 211B into which the positioning part 84 is inserted. However, for example, a positioning hole into which the positioning part 84 is inserted may be provided on the indoor side of the dovetail groove.

[0030] The screen door 5 is installed on the interior side, and the inner shoji screen 4 is guided to slide freely by a shoji rail provided between the screen door rail and the central protruding piece 213 on the upper frame 21. In addition, mohair 6 or a first insect-proof component 9 may be placed in the first gap between the screen door rail and the shoji rail between the upper frame 21 and the inner shoji screen 4, and a second insect-proof component 8 may be placed in the second gap between the shoji rail and the central protruding piece 213 between the upper frame 21 and the inner shoji screen 4. While a sliding window 1 has been given as an example of a building fixture to which the present invention applies, a single-sliding window in which one of the outer or inner sash is slidable and the other is fixed so as not to slide may also be used.

[0031] [Summary of the invention] The gap-sealing structure for joinery of the present invention comprises a frame body composed of an upper frame, a lower frame, and left and right vertical frames, a sliding door composed of an upper frame, a lower frame, left and right vertical frames, and a facing material, and supported by the frame body, and a screen door supported by the frame body, wherein the upper frame is provided with a screen door rail for slidingly guiding the screen door, a sliding door rail for slidingly guiding the sliding door, and a protruding piece facing the interior side surface of the sliding door in the depth direction, a first insect-proof component is placed in the first gap between the screen door rail and the sliding door rail between the upper frame and the sliding door, and a second insect-proof component is placed in the second gap between the sliding door rail and the protruding piece between the upper frame and the sliding door. According to the present invention, in a configuration in which the wind resistance of a shoji screen is enhanced by providing a shoji screen rail on the upper frame, insect resistance can be enhanced by placing a first insect-repellent component in a first gap located on one side in the depth direction relative to the shoji screen rail, and a second insect-repellent component in a second gap located on the other side in the depth direction.

[0032] In the gap-sealing structure for joinery of the present invention, it is preferable that the first insect-proof component is mohair, and the first gap is provided with a linear member fixed so as to penetrate the mohair and extend in the visible direction, and a screen door fall prevention member fixed to the screen door and configured to slide relative to the linear member. According to the present invention, when the screen door is slid, the fall prevention member can pass through the mohair fibers without being hindered by the mohair's sliding motion. Therefore, wind resistance and insect repellency can be improved, and the screen door can be prevented from falling.
