Summary of the Invention

Problems to be Solved by the Invention

[0004] Generally, since direct sunlight irradiated on the fitting from the outdoor side enters a large amount around the lower part of the fitting, there may occur thermal deformation in which the lower rail of the shoji contracts in the viewing direction. Further, when the lower rail softens due to heat from direct sunlight, the lower rail may bend due to the weight of a facing material such as glass stored in the shoji, and the shoji may be deformed. When the shoji is deformed, the engagement state between the shoji and the frame body may change, and there is a risk that the shoji rattles or the shoji comes off the frame body.

[0005] Therefore, the inventor has found a problem of providing a fitting capable of suppressing thermal deformation of the lower rail of the shoji.

Means for Solving the Problems

[0006] The fitting of the present disclosure includes a frame body having an upper frame, a lower frame, and left and right vertical frames, and having groove portions in the upper frame and the lower frame, and a panel material inside a frame body having an upper rail, a lower rail, and left and right vertical frames, and a shoji screen whose upper end portion and lower end portion are inserted into the groove portions and held by the upper frame and the lower frame. The lower frame has a height that covers the outdoor side surface of the lower rail of the shoji screen.

Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the fitting of the present disclosure will be described in detail with reference to the drawings. This embodiment shows a FIX window 1 as a fitting. The FIX window 1 is a so-called fixed window and is attached inside a frame 101 provided along the inner periphery of a rectangular opening 100 of a building structure. The FIX window 1 does not open or close the opening 100 except when the shoji screen 3 is removed for cleaning or the like. However, the fitting only needs to be one in which a load is applied to the lower rail of the shoji screen housed in the frame body, and is not limited to the FIX window. The fitting may be, for example, a sliding window.

[0009] FIG. 1 is a view of the FIX window 1 seen from the outdoor side. FIG. 2 is a view of the FIX window 1 seen from the indoor side. In FIGS. 3 to 6, the X1 direction indicates the outdoor side of the FIX window 1, and the X2 direction indicates the indoor side of the FIX window 1. Other windows (not shown), such as FIX windows and sliding windows, may be further attached inside the frame 101 on the outdoor side of the FIX window 1. Thereby, a double window is constructed inside the frame 101, and the heat insulation and sound insulation properties are further improved. The FIX window 1 of the present embodiment can be retrofitted on the indoor side of an existing window (not shown).

[0010] The FIX window 1 includes a frame body 2 provided inside the frame 101 and a shoji 3 housed inside the frame body 2. The frame body 2 is configured by framing an upper frame 21, a lower frame 22, and left and right vertical frames 23 and 24 in a rectangle. The shoji 3 is removably fitted inside the frame body 2.

[0011] The upper frame 21 of the frame body 2 is integrally extruded and formed of a resin material. The upper frame 21 has a first hollow portion 211 having a rectangular cross-section disposed on the outdoor side, a second hollow portion 212 having a rectangular cross-section disposed on the indoor side, and a flat plate-shaped substrate portion 213 connecting the upper ends of the first hollow portion 211 and the second hollow portion 212. The first hollow portion 211, the second hollow portion 212, and the substrate portion 213 extend over the entire length of the upper frame 21 in the extending direction. In the present embodiment, the first hollow portion 211 and the second hollow portion 212 protrude downward from the substrate portion 213 at the same height, but they do not necessarily have to protrude at the same height.

[0012] The first hollow portion 211 and the second hollow portion 212 are arranged in parallel at a distance in the indoor-outdoor direction. As a result, a groove portion 214 extending over the entire length in the extending direction of the upper frame 21 is formed between the first hollow portion 211, the second hollow portion 212, and the substrate portion 213. The groove portion 214 opens downward and accommodates the upper end portion of the shoji 3. The substrate portion 213 constitutes the inner bottom surface of the groove portion 214. An end portion of the first hollow portion 211 is integrally provided with a sealing portion 215 that protrudes toward the indoor side and elastically contacts the outdoor-side surface of the shoji 3. An end portion of the second hollow portion 212 is integrally provided with a fin portion 216 that protrudes toward the outdoor side and elastically contacts the indoor-side surface of the shoji 3. The upper frame 21 is fixed to the upper inner surface of the frame 101 by a fixing screw SC1 that penetrates the substrate portion 213.

[0013] The lower frame 22 of the frame body 2 is integrally extrusion-molded from a resin material. The lower frame 22 has a first hollow portion 221 having a hollow structure with a rectangular cross-section disposed on the outdoor side, a second hollow portion 222 having a hollow structure with a rectangular cross-section disposed on the indoor side, and a flat plate-shaped substrate portion 223 that connects the lower end portions of the first hollow portion 221 and the second hollow portion 222. The first hollow portion 221, the second hollow portion 222, and the substrate portion 223 extend over the entire length in the extending direction of the lower frame 22.

[0014] The first hollow portion 221 and the second hollow portion 222 are arranged in parallel at a distance in the indoor-outdoor direction. As a result, a groove portion 224 extending over the entire length in the extending direction of the lower frame 22 is formed between the first hollow portion 221, the second hollow portion 222, and the substrate portion 223, similarly to the upper frame 21. The groove portion 224 opens upward and accommodates the lower end portion of the shoji 3. The substrate portion 223 constitutes the inner bottom surface of the groove portion 224. An upper end portion of the first hollow portion 221 is integrally provided with a sealing portion 225 that protrudes toward the indoor side and elastically contacts the outdoor-side surface of the shoji 3. An upper end portion of the second hollow portion 222 is integrally provided with a fin portion 226 that protrudes toward the outdoor side and elastically contacts the indoor-side surface of the shoji 3. The lower frame 22 is fixed to the lower inner surface of the frame 101 by a fixing screw SC2 that penetrates the substrate portion 223.

[0015] The vertical frames 23 and 24 of the frame body 2 are integrally extruded and formed in a substantially L shape by a resin material respectively. The vertical frames 23 and 24 extend vertically between the upper frame 21 and the lower frame 22. The vertical frames 23 and 24 have substrate portions 231 and 241 that extend with a predetermined width along the vertical direction of the picture frame 101, outdoor wall portions 232 and 242 that extend substantially at a right angle from the outdoor ends of the substrate portions 231 and 241 toward the inside of the picture frame 101, and abutting piece portions 233 and 243 that extend substantially at a right angle from the inner ends of the outdoor wall portions 232 and 242 toward the indoor side.

[0016] The abutting piece portions 233 and 243 are formed to be narrower in width than the substrate portions 231 and 241 so as to contact the outdoor side surface of the shoji 3. Sealing portions 234 and 244 that elastically contact the outdoor side surface of the shoji 3 are integrally provided at the tips of the abutting piece portions 233 and 243 respectively. The vertical frames 23 and 24 are fixed to the left and right inner side surfaces of the picture frame 101 respectively by fixing screws SC3 and SC4 that penetrate the substrate portions 231 and 241.

[0017] The shoji 3 is configured by accommodating a facing material 35 such as glass through a glazing channel 351 inside a frame body 30 formed by rectangularly framing an upper rail 31, a lower rail 32, and left and right vertical frames 33 and 34. As shown in FIG. 3, the upper rail 31 and the lower rail 32 are each composed of a metal core material 311 and 321, a resin cover material 312 and 322 that covers the outside thereof, and resin upper cover materials 313 and lower cover materials 323 that are attached to the upper end surface and the lower end surface of the resin cover materials 312 and 322 respectively. As shown in FIG. 4, the vertical frames 33 and 34 are each composed of a metal core material 331 and 341 and a resin cover material 332 and 342 that covers the outside thereof.

[0018] As shown in FIG. 1, the shoji 3 has a vertical victory structure in which the upper rail 31 and the lower rail 32 are arranged between the left and right vertical frames 33 and 34. Specifically, the left and right vertical frames 33 and 34 extend over the entire length in the height direction of the shoji 3. The upper rail 31 and the lower rail 32 are arranged between the left and right vertical frames 33 and 34 and connect the upper ends and the lower ends of the vertical frames 33 and 34 respectively. A substantially U-shaped handle 36 is attached to the central portion of the indoor side surface of the lower rail 32.

[0019] As shown in FIGS. 1, 3, and 5, the lower frame 22 has a height that covers the outdoor side surface 32a of the lower rail 32 of the shoji 3 when viewed from the outdoor side. Specifically, as shown in FIG. 3, the height h1 of the first hollow portion 221 of the lower frame 22 is equal to the height of the lower rail 32 of the shoji 3 in a state where it is attached to the frame body 2. The upper end surface 221a of the first hollow portion 221 is disposed at substantially the same height as the upper end surface 32b of the lower rail 32. The glazing channel 351 that supports the lower end portion of the face material 35 is disposed at substantially the same height as the upper end surface 221a of the first hollow portion 221 or protrudes slightly above the upper end surface 221a.

[0020] Due to the first hollow portion 221 of the lower frame 22, the outdoor side surface 32a of the lower rail 32 of the shoji 3 is not exposed to the outdoor side. Therefore, the amount of direct sunlight irradiated on the lower rail 32 is reduced, and thermal deformation of the lower rail 32 is suppressed. Since the height h1 of the first hollow portion 221 of the lower frame 22 is equal to the height of the lower rail 32 of the shoji 3, the face material 35 is not shielded. Therefore, there is no possibility that the amount of daylight that the shoji 3 can take into the room through the face material 35 will decrease. Further, the first hollow portion 221 of the lower frame 22 of the present embodiment has a hollow structure and is excellent in heat insulation, so the effect of suppressing thermal deformation of the lower rail 32 is improved.

[0021] The shoji 3 is inserted into the groove portion 214 of the upper frame 21 and the groove portion 224 of the lower frame 22 in a kendon manner from the indoor side as shown in FIG. 6. First, the upper end portion of the shoji 3 is inserted deep into the groove portion 214 of the upper frame 21. Next, the lower end portion of the shoji 3 moves from the indoor side toward the outdoor side on the second hollow portion 222 of the lower frame 22 and is aligned with the groove portion 224 of the lower frame 22. Thereafter, as the shoji 3 descends, the lower end portion of the shoji 3 is inserted into the groove portion 224 of the lower frame 22. As a result, the upper end portion and the lower end portion of the shoji 3 are respectively accommodated in the groove portions 214 and 224, and the shoji 3 is fitted and held between the upper frame 21 and the lower frame 22. The left and right vertical frames 23 and 24 only bring the sealing members 234 and 244 at the tips of the contact piece portions 233 and 243 into contact with the outdoor side surfaces of the vertical frames 33 and 34 of the shoji 3 and do not hold the shoji 3.

[0022] As shown in FIGS. 2, 3, and 5, the height of the lower frame 22 of the present embodiment is lower on the indoor side than on the outdoor side of the groove portion 224. Specifically, as shown in FIG. 3, the height h2 of the second hollow portion 222 of the lower frame 22 is lower than the height h1 of the first hollow portion 221. Therefore, the insertion amount of the upper end portion of the shoji 3 into the groove portion 214 of the upper frame 21 required for the lower end portion of the shoji 3 to straddle the second hollow portion 222 can be reduced. As a result, the depth of the groove portion 214 of the upper frame 21, that is, the height of the first hollow portion 211 and the second hollow portion 212 of the upper frame 21 downward, can be suppressed.

[0023] A resin liner (not shown) for supporting the lower end portion of the shoji 3 may be provided in the groove portion 224 of the lower frame 22, but the lower frame 22 of the present embodiment does not have a resin liner as shown in FIG. 5. The lower end surface 32c of the lower rail 32 of the shoji 3 attached to the frame body 2 is directly placed on the substrate portion 223 which is the inner bottom surface of the groove portion 224. Since there is no resin liner, the depth of the groove portion 224 of the lower frame 22 can be made shallower, that is, the heights h1 and h2 of the lower frame 22 can be made lower respectively.

[0024] When the shoji 3 is attached to the frame body 2, the upper end portion of the shoji 3 is accommodated in the groove portion 214 of the upper frame 21 and engages with the upper frame 21. The lower end portion of the shoji 3 is accommodated in the groove portion 224 of the lower frame 22 and engages with the lower frame 22. The sealing portion 215 and the fin portion 216 of the upper frame 21 contact the upper end portion of the shoji 3 from the outdoor side and the indoor side respectively. Thereby, in the upper frame 21, prevention of rattling of the upper end portion of the shoji 3, prevention of intrusion of dust etc. from the outside, and ensuring of airtightness are achieved. The sealing portion 225 and the fin portion 226 of the lower frame 22 contact the lower end portion of the shoji 3 from the outdoor side and the indoor side respectively. Thereby, in the lower frame 22, prevention of rattling of the lower end portion of the shoji 3, prevention of intrusion of dust etc. from the outside, and ensuring of airtightness are achieved.

[0025] As described above, according to the FIX window 1 of the present embodiment, the following effects can be obtained. That is, the FIX window 1 includes a frame body 2 having an upper frame 21, a lower frame 22, and left and right vertical frames 23, 24, and having groove portions 214, 224 in the upper frame 21 and the lower frame 22, and a muntin 30 having an upper rail 31, a lower rail 32, and left and right vertical muntins 33, 34, with a facing material 35 on the inner side thereof, and a shoji 3 having upper and lower end portions inserted into the groove portions 214, 224 to be held by the upper frame 21 and the lower frame 22. The lower frame 22 has a height that covers the lower rail 32 of the shoji 3. According to this, thermal deformation of the lower rail 32 of the shoji 3 can be suppressed. Therefore, a change in the engagement state between the shoji 3 and the frame body 2 due to thermal deformation of the shoji 3 is suppressed, and the possibility that the shoji 3 rattles or the shoji 3 comes off the frame body 2 can be reduced.

[0026] In the present embodiment, the height of the lower frame 22 is lower on the indoor side than on the outdoor side of the groove portion 224. According to this, when inserting the upper end portion of the shoji 3 into the groove portion 214 of the upper frame 21 in a kendon manner, the amount of insertion into the groove portion 214 required for the lower end portion of the shoji 3 to straddle the second hollow portion 222 on the indoor side of the groove portion 224 can be reduced. As a result, the depth of the groove portion 214 of the upper frame 21, that is, the height of the first hollow portion 211 and the second hollow portion 212 of the upper frame 21 downward, can be suppressed, so that the height of the upper rail 31 of the shoji 3 can be lowered.

[0027] The lower frame 22 of the present embodiment has a first hollow portion 221 on the outdoor side of the groove portion 224. The first hollow portion 221 has a hollow structure and is excellent in heat insulation, so the effect of suppressing thermal deformation of the lower rail 32 is improved.
