Description

[Technical Field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, fittings have been known that include a shoji screen with drainage holes in the bottom frame (see, for example, Patent Document 1). Rainwater that has seeped into the inside of the bottom frame is drained to the outside of the bottom frame through the drainage holes. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-218485 Summary of the Invention [Problem to be solved by the invention]

[0004] However, if heavy rain causes rainwater to accumulate in the sill and block the drainage holes in the sill, the rainwater will no longer be able to drain, and there is a risk that the rainwater will leak into the interior of the room. Therefore, there is a demand for fittings that can drain rainwater smoothly even in such cases.

[0005] The present disclosure aims to provide a building fixture with improved watertight performance by smoothly draining rainwater that accumulates within the bottom frame. [Means for solving the problem]

[0006] The present disclosure relates to a fitting comprising a frame body and a shoji screen having a bottom frame disposed within the frame body, the bottom frame having an air introduction hole penetrating the visible surface on the interior side in the forward direction.

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. A description will be given of a fitting 1 according to one embodiment. In this specification, the "visible direction" refers to the face direction of the surface material of the fitting 1 placed in an opening formed in the wall of a building, and the "visible direction" refers to the thickness direction of the surface material (i.e., the depth direction). The "visible direction" also refers to the indoor / outdoor direction. The "visible surface" refers to the surface of the fitting 1 facing the outside and the inside of the room, respectively, and the "visible surface" refers to the surface of the fitting 1 extending in the indoor / outdoor direction. In the drawings, the outdoor side of the fitting 1 is referred to as the outdoor side X1, and the indoor side of the fitting 1 is referred to as the indoor side X2. The "horizontal direction" of the outer shoji screen 5 is also referred to as the left-right direction.

[0009] As shown in Figure 1, the building fixture 1 comprises a frame body 2 attached to an opening in a building frame (not shown), a post 3 arranged within the frame body 2, a FIX section 4 arranged on the inside X2 of the frame body 2 on one side of the post 3 in the left-right direction, an outer shoji screen 5 arranged on the outside X1 of the frame body 2 so as to be movable in the left-right direction, and a pleated screen 6 (retractable screen) arranged on the inside X2 of the frame body 2 so as to be retractable on the other side of the post 3 in the left-right direction.

[0010] The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape.

[0011] 2 and 3, the upper frame 21 has an upper frame main body 211. The upper frame main body 211 has an upper frame exterior groove 211a formed on the exterior side X1 and open downward, and an upper frame interior groove 211b formed on the interior side X2 and open downward.

[0012] The upper end of the outer shoji screen 5 is placed in the upper frame outer groove 211a on the outer side X1 of the upper frame 21. The upper frame outer groove 211a guides the left-right movement of the upper end of the outer shoji screen 5.

[0013] The upper frame interior groove 211b has a fixed glass placement groove 211d (see FIG. 3) formed on one side in the left-right direction (the right side in FIG. 1), and a screen door placement groove 211c (see FIG. 2) formed on the other side in the left-right direction (the left side in FIG. 1). As shown in FIG. 2, a screen door attachment 211e is placed in the screen door placement groove 211c. The screen door placement groove 211c guides the left-right movement of the upper end of the pleated screen door 6 via the screen door attachment 211e. As shown in FIG. 3, the upper end of the glass panel 41 of the FIX unit 4 is placed in the fixed glass placement groove 211d.

[0014] 2 and 3, the lower frame 22 has a lower frame main body 221. The lower frame main body 221 has a lower frame rail 221a formed on the outdoor side X1 and protruding upward, and a lower frame indoor side groove 221b formed on the indoor side X2 and opening upward.

[0015] The lower end of the outer shoji screen 5 is arranged on the lower frame rail 221a on the outside X1 side of the lower frame 22. The lower frame rail 221a guides the movement of the lower end of the outer shoji screen 5 in the left-right direction.

[0016] The lower frame interior groove 221b has a fixed glass arrangement groove 221d (see FIG. 3) formed on one side in the left-right direction, and a screen door arrangement groove 221c (see FIG. 2) formed on the other side in the left-right direction. As shown in FIG. 2, a screen door attachment 221e is arranged in the screen door arrangement groove 221c. The screen door arrangement groove 221c guides the left-right movement of the lower end of the pleated screen door 6 via the screen door attachment 221e. As shown in FIG. 3, the lower end of the glass panel 41 of the FIX unit 4 is arranged in the fixed glass arrangement groove 221d.

[0017] As shown in Figure 1, the mullion 3 is arranged extending vertically at a midpoint in the left-right direction on the interior side X2 of the frame body 2. The opening of the frame body 2 is divided into left and right halves midway in the left-right direction by the mullion 3. As a result, a FIX section 4 is formed on one side of the frame body 2 in the left-right direction, and an opening 25 that is opened and closed by an outer screen 5 is formed on the other side of the frame body 2 in the left-right direction.

[0018] As shown in Fig. 1, the FIX section 4 is configured by fixing a glass panel 41 as a surface material to the mullion 3 and the frame body 2 on one side in the left-right direction (the right side in Fig. 1) of the mullion 3 within the frame body 2. The FIX section 4 is a fixed window that cannot be opened or closed.

[0019] As shown in Figure 4, the outer shoji screen 5 is a shoji screen that can be opened and closed by sliding left and right (horizontally) within the frame body 2 on the outside X1 of the frame body 2. The outer shoji screen 5 is configured to be able to open and close an opening 25 formed on the other side (left side in Figure 1) of the FIX unit 4. When viewed from the indoor / outdoor direction, the outer shoji screen 5 is in a closed position when it overlaps the opening 25, and is in an open position when it is moved to the outside X1 of the FIX unit 4 by moving left and right.

[0020] As shown in Figures 2 and 4, the outer shoji screen 5 is constructed by fitting a panel 55 made of two pieces of glass onto the inner periphery of a rectangular frame body 50 made up of an upper frame 51, a lower frame 52, a vertical frame 53 located at the front end of the door, and a vertical frame 54 located at the rear end of the door.

[0021] A handle 531 is attached to the vertical frame 53 located on the door edge side, as shown in Fig. 1. The handle 531 is attached to the visible surface of the inner periphery of the vertical frame 53 in the left-right direction, on the room side X2, closer to the interior than the face material 55 of the outer shoji screen 5, as shown in Fig. 4.

[0022] As shown in Figure 2, the outer shoji screen 5 has its upper end arranged in the upper frame outer groove 211a of the upper frame 21 so as to be movable in the left-right direction, and its lower end engaged with the lower frame rail 221a of the lower frame 22 so as to be movable in the left-right direction. The lower frame 52 is provided with a plurality of door rollers 56 (see Figures 6 and 7) that roll on the lower frame rail 221a of the lower frame 22.

[0023] 5, the lower frame 52 of the outer shoji screen 5 moves left and right while abutting against the airtight material 222 provided on the facing surface of the lower frame 22 facing the outside X1. The airtight material 222 provided on the facing surface of the lower frame 22 facing the outside X1 abuts against the facing surface 52a of the lower frame 52 of the outer shoji screen 5 on the inside X2 side.

[0024] Next, we will explain the drainage structure of the lower frame 52 of the outer shoji screen 5. As shown in Figure 5, the lower frame 52 has a composite structure in which a resin frame material 58 is attached to the indoor side X2 of a metal frame material 57. The metal frame material 57 and the resin frame material 58 extend in the left-right direction (horizontal direction) as shown in Figures 6 and 7.

[0025] As shown in Figures 5 to 7, the metal frame material 57 has a rectangular cylindrical hollow frame 571 having a hollow portion 571a, a glass placement groove 578 (panel placement groove) formed on the upper side of the hollow frame 571 and opening upward, and an extension portion 579 extending downward from the end of the hollow frame 571 on the outside side X1.

[0026] As shown in Figures 5 to 7, the hollow frame 571 of the metal frame material 57 has a pair of upper door roller arrangement openings 572 (see Figure 6) formed on both left-right end sides, a plurality of lower door roller arrangement openings 573 (drainage holes) (see Figures 5 and 7) formed on both left-right end sides, two upper drainage introduction openings 574 (see Figures 5 and 6), and two air introduction holes 575 (see Figures 5 and 7).

[0027] As shown in Fig. 6, the pair of upper door roller arrangement openings 572 are formed at both left and right end sides of the upper plate 571b of the hollow frame 571 of the metal frame material 57, penetrating in the up-down direction and extending a predetermined length in the left-right direction. The upper door roller arrangement openings 572 are formed as rectangular openings extending a predetermined length in the left-right direction. The upper sides of the multiple door rollers 56 are arranged in the upper door roller arrangement openings 572.

[0028] In addition to accommodating the upper sides of multiple door roller arrangement openings 572, the pair of upper door roller arrangement openings 572 also function as drainage introduction holes that introduce rainwater that has entered the glass arrangement groove 578 from the upper side of the outside side X1 of the lower frame 52 of the outer shoji screen 5 through the upper panel 571b of the hollow frame 571 of the metal frame material 57 into the interior of the hollow frame 571.

[0029] 7, the plurality of lower door roller arrangement openings 573 are formed penetrating in the up-down direction at both left-right end sides of the lower plate 571c of the hollow frame 571 of the metal frame material 57, and extend a predetermined length in the left-right direction. Each of the plurality of lower door roller arrangement openings 573 is formed as a rectangular opening extending a predetermined length in the left-right direction.

[0030] The plurality of lower door roller arrangement openings 573 are formed below the pair of upper door roller arrangement openings 572. The lower sides of the plurality of door rollers 56 are arranged in the lower door roller arrangement openings 573. The plurality of lower door roller arrangement openings 573 are arranged below the air introduction holes 575, which will be described later.

[0031] The lower door roller arrangement openings 573 accommodate the lower sides of the multiple door rollers 56, and also function as drainage holes that discharge rainwater that has been introduced into the hollow frame 571 of the bottom stile 52 to the outside. In this embodiment, the lower door roller arrangement openings 573 function as drainage holes that discharge rainwater to the outside, but this is not limiting. Apart from the lower door roller arrangement openings 573, drainage holes for drainage may be provided in the lower plate 571c of the hollow frame 571 of the metal stile 57.

[0032] As shown in Figures 5 and 6, the two upper drainage inlet openings 574 are formed in positions inside the pair of upper door roller arrangement openings 572 in the left-right direction of the upper plate 571b of the hollow frame 571 of the metal frame material 57. The two upper drainage inlet openings 574 are each formed by vertically penetrating the upper plate 571b of the hollow frame 571 of the metal frame material 57. The two upper drainage inlet openings 574 each introduce rainwater that has infiltrated into the glass arrangement groove 538 of the lower frame 52 from the upper side of the outside X1 of the lower frame 52 of the outer shoji screen 5 from the upper plate 571b of the hollow frame 571 of the metal frame material 57 into the interior of the hollow frame 571.

[0033] 5 and 7, the two air introduction holes 575 are formed on the indoor facing surface 571e (facing surface) of the vertical plate 571d on the indoor side X2 of the hollow frame 571 of the metal frame material 57. The two air introduction holes 575 are located on the outdoor side X1 of the airtight material 222 provided on the lower frame 22 against which the lower frame 52 of the outer shoji screen 5 abuts.

[0034] Next, we will explain the flow of water when rainwater enters the bottom frame 52 of the outer shoji screen 5. As shown in Figure 8, when rainwater enters the glass arrangement groove 578 of the bottom frame 52 from the upper end of the outside X1 of the bottom frame 52 of the outer shoji screen 5, the rainwater is introduced into the hollow frame 571 of the metal frame material 57 through the upper drainage introduction opening 574 and the upper door roller arrangement opening 572 (see Figure 6).

[0035] Then, the rainwater introduced into the hollow frame 571 is discharged to the outside below the lower frame 52 through the lower roller arrangement opening 573. The rainwater discharged to the outside below the lower frame 52 is collected in the lower frame 22 and discharged to the outside through drainage holes (not shown) provided in the lower frame 22.

[0036] Here, heavy rain due to a typhoon, for example, may cause a large amount of rainwater to seep into the hollow frame 571 from the upper end of the bottom frame 52 through the bottom door roller arrangement opening 573 (drainage hole). In this case, rainwater that cannot be drained accumulates in the bottom frame 22, causing the bottom door roller arrangement opening 573 (drainage hole) of the bottom frame 52 to become submerged, and water accumulates in the hollow frame 571.

[0037] In such a case, it becomes impossible to introduce outside air into the hollow frame 571, and the inside will eventually become filled with water.Since the pressure on the indoor side X2 is lower than the pressure on the outdoor side X1, the water accumulated inside the hollow frame 571 may leak out to the indoor side X2 and enter the room.

[0038] In contrast to this, in the present disclosure, air inlet holes 575 are provided on the indoor-side facing surface 571e of the vertical plate 571d on the indoor-side X2 of the hollow frame 571 of the metal frame material 57. As a result, as shown in Fig. 8, by introducing outside air into the hollow portion 571a at a position where it is not submerged and promoting drainage, it is possible to prevent the inside of the hollow frame 571 from becoming filled with water.

[0039] This embodiment provides the following advantages. The fitting 1 of this embodiment is equipped with an outer shoji screen 5 having a bottom frame 52, and the bottom frame 52 has an air inlet hole 575 that penetrates the visible surface of the indoor side X2 in the forward direction. This allows the air inlet hole 575 to introduce outside air from the indoor side X2 into the hollow frame 571. Therefore, in the outer shoji screen 5, outside air is introduced into the hollow frame 571, which prevents the hollow frame 571 from becoming filled with water. This prevents water from entering the indoor side X2 of the outer shoji screen 5, improving watertightness.

[0040] Furthermore, in this embodiment, the outer screen 5 is configured to be able to move left and right along the lower frame 22 while in contact with the airtight material 222 provided on the lower frame 22, and the air inlet hole 575 is positioned further outside X1 than the airtight material 222. This allows outside air to be introduced into the hollow frame 571 through the air inlet hole 575 on the outside X1 of the part where airtightness is ensured by the airtight material 222. This further improves the watertightness of the outer screen 5.

[0041] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0042] In the above embodiment, the fitting is applied to a composite sash, but the present invention is not limited to this and can be applied to not only composite sashes but also metal sashes, aluminum heat-insulating sashes, and resin sashes.

[0043] In the above embodiment, a plurality of air inlet holes 575 are provided in the bottom frame 52, but the number and arrangement of the air inlet holes are not limited. The number and left-right positions of the air inlet holes vary depending on the size of the window of the fixture and the desired performance. [Explanation of symbols]
