[0007] Hereinafter, a fitting A according to an embodiment of the present invention will be described with reference to the drawings. In the following description, the same reference numerals in different drawings indicate parts having the same functions, and duplicated descriptions in each drawing will be omitted as appropriate. In the following description, the various components formed from resin moldings are components related to the thermal insulation properties of the fitting A.

[0008] As shown in Figures 1 and 2, the building fixture A has a frame 1 fixed to the inner periphery of an opening a1 in the main body a, and a sliding window with an inner screen 2 and an outer screen 3 arranged so that they can slide freely in the width direction (hereinafter referred to as the left-right direction).

[0009] The frame 1 has a framed structure having an upper frame 1A, a lower frame 1B, a left vertical frame 1C, and a right vertical frame 1D. The upper frame 1A, the lower frame 1B, the left vertical frame 1C, and the right vertical frame 1D each comprise an upper frame indoor inner member 10, a lower frame indoor inner member 11, a left vertical frame indoor inner member 12, and a right vertical frame indoor inner member 13 on the indoor side, and an upper frame outdoor member 14, a lower frame outdoor member 15, a left vertical frame outdoor member 16, and a right vertical frame outdoor member 17 on the outdoor side, and these both indoor inside and outdoor outside members are configured as an integrated unit. The upper frame interior side member 10 of the upper frame 1A comprises an upper frame interior side rail member 100 formed from an aluminum shaped material and a resin member 101 formed from a resin shaped material. The upper frame interior rail member 100 of the upper frame 1A is provided with an upper frame interior shoji rail 10A, is positioned on the exterior side of the resin member 101, and is integrated with the resin member 101 by engagement. The upper frame exterior frame member 14 of the upper frame 1A is equipped with an upper frame exterior rail member 140 on which an upper frame outer screen rail 14A is provided, and an upper frame screen door side rail member 141 on which an upper frame screen door rail 14B is provided. The upper frame room outer rail member 140 and the upper frame screen door side rail member 141 are integrated together by engaging with each other. The upper frame interior rail member 100 and the upper frame exterior rail member 140 are connected via a connecting member 18 formed from a resin molding material. The connecting member 18 is fixed to connect the upper frame interior side rail member 10 and the upper frame exterior side rail member 140 by crimping the connecting portion between the upper frame interior side rail member 100 and the upper frame exterior side rail member 140. Here, the left vertical frame interior side member 12 of the left vertical frame 1C is formed from a resin molding material, and the left vertical frame exterior side member 16 is formed from an aluminum molding material. The right vertical frame interior member 13 of the right vertical frame 1D is formed from a resin profile material, and the right vertical frame exterior member 17 is formed from an aluminum profile material.

[0010] The lower frame 1B comprises a lower frame body 10B and a lower frame cover 11B. The lower frame body 10B has a lower frame interior side member 11 and a lower frame exterior side member 15 made of aluminum molding material, and is connected via a connecting member 18 formed of a resin molding material. The connecting member 18 is fixed to connect the lower frame indoor side member 11 and the lower frame outdoor side member 15 by crimping the connecting portion between the lower frame indoor side member 11 and the lower frame outdoor side member 15. In addition, the connecting member 18 is arranged in an area of ​​projected width extending from the underside of the inner screen 2 to the underside of the outer screen 3, thereby ensuring thermal insulation on the inside of the room.

[0011] The lower frame interior side component 11 is provided with a lower frame inner shoji rail 11A over the entire area in the left-right direction. The lower frame exterior member 15 has a lower frame outer screen rail 15A provided over its entire left-right area, and a lower frame screen rail 15B provided over its entire left-right area on its outermost surface. The rollers 20 of the inner shoji 2 are placed on the lower frame inner shoji rail 11A, and the rollers 30 of the outer shoji 3 are placed on the lower frame outer shoji rail 15A. As the rollers 20 roll on the lower frame inner shoji rail 11A and the rollers 30 roll on the lower frame outer shoji rail 15A, the inner shoji 2 and outer shoji 3 open and close in the left and right directions.

[0012] The lower frame screen rail 15B is positioned so that its upper end 150B is lower than the lower frame outer screen rail 15A, thereby creating a step between the lower frame screen rail 15B and the lower frame outer screen rail 15A, improving drainage from the inside to the outside of the room. In addition, the upper end 150B of the lower frame screen rail 15B is at approximately the same height as the upper side surface 150 of the lower frame outdoor member 15, which allows the area between the upper side surface 150 of the lower frame outdoor member 15 and the upper end 150B of the lower frame screen rail 15B to be approximately flat on the outside of the lower frame outdoor member 15, thereby improving pedestrian safety and design.

[0013] The lower frame cover 11B is intended to ensure insulation and reduce the step of the lower frame 1B, and includes an indoor side cover 110 and a rail-interval cover 111 made from resin molding material. As shown in FIG. 3, the indoor side cover 110 is fitted onto the indoor side of the lower frame inner shoji rail 11A and is attached over the entire area of ​​the lower frame 1B. The upper surface of the indoor side cover 110 is approximately flush with the lower frame interior shoji rail 11A, eliminating any step caused by the lower frame interior shoji rail 11A. Returning to Figure 1 to continue the explanation, a recess a20 having a thickness approximately equal to that of the indoor side cover 110 is provided on the floor surface a2 side, and by inserting and fixing the indoor side cover 110 into this recess a20, the upper surface of the indoor side cover 110 and the upper surface of the floor surface a2 are made flush with each other.

[0014] The rail-space cover 111 is fitted between the lower frame inner shoji rail 11A and the lower frame outer shoji rail 15A, and is attached only to the area below the closed outer shoji 3, as shown in Figure 3. As a result, drainage is ensured on the upper surface of the lower frame 1B on the side of the closed inner screen 2, and this contributes to cost reduction compared to the conventional system in which an exterior cover is attached to the entire area of ​​the lower frame 1B. The upper surface of the rail-space cover 111 is approximately flush with the lower frame inner shoji rail 11A and the lower frame outer shoji rail 15A, eliminating the step caused by the lower frame inner shoji rail 11A and the lower frame outer shoji rail 15A, ensuring pedestrian safety when the outer shoji 3 is open. In addition, the rail-to-rail cover 111 has a protrusion 1110 (see Figure 1) that protrudes toward the inside of the room so as to fit under the hanging piece 21 that is used to guide the inner screen 2 and prevent it from falling off. The tip of the protrusion 1110 protrudes enough to abut or come close to the shoji rail 11A inside the lower frame, which allows the rail-to-rail cover 111 to be positioned when installed, improves insulation toward the inside of the room, and makes the rail-to-rail cover 111 less likely to come off.

[0015] As shown in Fig. 1 and Fig. 2, the inner screen 2 and the outer screen 3 are made up of an upper frame 4, a lower frame 5, a door stop frame 6, and a door frame 7. The inner screen 2 has a frame 2A, and the outer screen 3 has a frame 3A. A double-pane glass 8 is fitted into each of these frames. The upper frame 4 is constructed by combining an outdoor member A1 and an indoor member B1, and the lower frame 5 is constructed by combining an outdoor member A2 and an indoor member B1. The upper frame 4 and the lower frame 5 use the same shaped indoor component B1 and are arranged symmetrically from top to bottom. A hanging piece 21 is formed on the exterior side member A2 of the lower frame 5. The door stop frame 6 of the inner screen 2 and the outer screen 3 has an exterior member A3 and an interior member B2 and is constructed by combining the two members. The interlocking frame 7 of the inner screen 2 has an exterior member A4 and an interior member B3 and is constructed by combining the two members. The mating frame 7 of the outer screen 3 has an exterior part A5 and an interior part B4 and is constructed by combining the two parts. The exterior members A1 to A5 are formed from aluminum material, and each has an exterior side wall C of the glass opening 22 of the frame 2A. The indoor members B1 to B4 are formed from a resin molding material having heat insulating properties, and each has an indoor side wall D of the glass opening 22 of the frame 2A.

[0016] As can be seen from Figure 3, a fitting A equipped with such a lower frame 1B has an indoor side cover 110 attached to the entire area of ​​the lower frame indoor side member 11, thereby ensuring insulation to the indoor side. Furthermore, since the rail-to-rail cover 111 is attached only to the area below the closed outer screen 3, drainage is ensured on the upper surface of the lower frame 1B on the side of the closed inner screen 2, and this contributes to cost reduction compared to the conventional method in which an exterior cover is attached to the entire area of ​​the lower frame 1B. Furthermore, since the rail-to-rail cover 111 is attached only to the area below the closed outer screen 3, drainage is ensured on the upper surface of the lower frame 1B on the side of the closed inner screen 2, and this contributes to cost reduction compared to the conventional method in which an exterior cover is attached to the entire area of ​​the lower frame 1B. In addition, in the conventional rail-to-rail cover 111 in which the outer cover is attached to the entire area of ​​the lower frame 1B, the area of ​​the rail-to-rail cover 111 on the closed inner screen 2 side is exposed to wind and rain. If mud or dirt adheres to this area, it will get into the small gap between the rail-to-rail cover 111 and the rail, preventing drainage. This makes it necessary to frequently remove the rail-to-rail cover 111 for cleaning. Since the rail-to-rail cover 111 of the embodiment is attached only to the area below the closed outer screen 3, the rail-to-rail cover 111 is not provided in the area exposed to wind and rain, and mud and dirt are less likely to accumulate. Furthermore, the embodiment drastically reduces the frequency of cleaning work performed by removing the rail-to-rail cover 111. In addition, since the rail-interval cover 111 is attached only to the area below the closed outer screen 3, it is half the length of the interior cover 110, which contributes to saving materials and ultimately reducing costs. Furthermore, since the indoor side cover 110 and the lower frame indoor side member 11 ensure thermal insulation to the indoor side, there is no need to attach a cover to the outdoor side (the side of the lower frame screen rail 15B) of the lower frame outer shoji rail 15A, which contributes to saving materials and ultimately to reducing costs compared to the conventional method in which an outdoor side cover is attached to the entire area of ​​the lower frame 1B. Furthermore, when the outer screen 3 is opened, the interior cover 110 and the rail-to-rail cover 111 make the upper surface of the lower frame 1B approximately flat with no steps. Therefore, the building material A can ensure the drainage of the sill 1B while ensuring thermal insulation, and can reduce costs by saving on the materials required for insulation.Furthermore, since the upper surface of the sill 1B is approximately flat when the outer screen 3 is opened, it can contribute to barrier-free access.

[0017] The above describes in detail an embodiment of the fitting A according to the present invention with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the present invention includes design changes and the like that do not deviate from the gist of the present invention.

[0018] Furthermore, the above-described embodiments can be combined by utilizing each other's technologies, so long as there are no particular contradictions or problems in the objects, configurations, and the like. [Explanation of symbols]
