Description

[Technical field]

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

[0002] Conventionally, fittings have been known in which the frame housing a shoji screen is made up of a metal frame and a resin cover material provided on the surface of the metal frame (see, for example, Patent Document 1, etc.). This type of fitting has excellent heat insulation and moisture resistance because the resin cover material, which has a lower thermal conductivity than metal, is placed on the inner surface of the frame. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-109099 A Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, the projected dimensions of the frame that houses the shoji screen differ depending on the type of shoji screen. Therefore, in the past, it was necessary to prepare multiple types of resin cover materials with projected dimensions that corresponded to the projected dimensions of the frame.

[0005] Therefore, the inventor has discovered the problem of providing a fixture that is equipped with a resin cover material that is highly versatile, eliminating the need to prepare multiple types of resin cover material for each expected dimension of the frame body. [Means for solving the problem]

[0006] The fixture of the present disclosure comprises a frame body that is attached to an opening in a building structure and is composed of an upper frame, a lower frame, and left and right vertical frames framed in a rectangular shape, and a shoji screen that is placed inside the frame body, and at least one of the upper frame, lower frame, and vertical frames is composed of a frame body main body and a resin cover material provided on the inner surface of the frame body main body, and the resin cover material is composed of a number of cover members that are arranged along the front direction of the frame body and overlap each other with an overlapping margin. [Brief description of the drawings]

The lower frame 32 of the outer screen 3 is provided with a wheel 36 that rolls on the outdoor rail 221 of the lower frame 22.

[0012] The inner screen 4 is constructed by fitting a panel 45 made of two pieces of glass inside a frame body 40 made of an upper frame 41, a lower frame 42, a vertical frame 43 located on the door end side, and an inner meeting frame 44 located on the door tail side, assembled into a rectangular shape. The inner screen 4 is engaged with the interior rails 212, 222 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction. The lower frame 42 of the inner screen 4 is provided with a wheel 46 that rolls on the interior rail 222 of the lower frame 22.

[0013] As shown in Figures 2 and 3, the upper frame 31, lower frame 32, vertical frame 33 and outer meeting frame 34 of the outer screen 3 each have a composite structure in which plastic frame materials 312, 322, 332, 342 are attached to the indoor side of metal frame materials 311, 321, 331, 341. The upper frame 41, lower frame 42, vertical frame 43 and inner meeting frame 44 of the inner screen 4 each have a composite structure in which plastic frame materials 412, 422, 432, 442 are attached to the indoor side of metal frame materials 411, 421, 431, 441. This gives the outer screen 3 and inner screen 4 excellent heat insulation and moisture resistance.

[0014] The screen door 5 is engaged with the screen door rails 213, 223 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction.

[0015] Next, the configuration of the frame body 2 will be described in more detail. As shown in FIG. 2, the upper frame 21 has a composite structure in which the resin cover materials 215, 216 are attached to the inner surface of the metal frame body 214, which is the frame body main body. Therefore, it has excellent heat insulation and dew prevention properties. The resin cover material 215 is arranged between the outdoor rail 211 and the indoor rail 212 in the upper frame 21. The resin cover material 216 is arranged on the indoor side of the indoor rail 212 in the upper frame 21, and is provided from the indoor side of the indoor rail 212 to the inner surface of the metal frame body 214. The resin cover material 216 has an angle part 2161 integrally therewith, which protrudes indoors beyond the indoor end part 214a of the metal frame body 214. The resin cover materials 215, 216 are provided over the entire length of the upper frame 21 in the extension direction.

[0016] As shown in Figures 2 and 3, the lower frame 22 has a composite structure in which resin cover materials 6, 7 are attached to the inner surface of the metal frame body 224, which is the frame body main body. Therefore, it has excellent heat insulation and moisture resistance. As shown in Figure 2, the metal frame body 224 is divided into an outdoor metal frame body 2241 and an indoor metal frame body 2242 between the outdoor rail 221 and the indoor rail 222. The outdoor metal frame body 2241 and the indoor metal frame body 2242 are connected by a resin connecting material 2243.

[0017] The resin cover material 6 is disposed between the outdoor side rail 221 and the indoor side rail 222 of the lower frame 22. More specifically, the resin cover material 6 is disposed on the inner surface of the outdoor side metal frame body 2241, which is further outdoor than the resin connecting material 2243. The resin cover material 7 is disposed on the indoor side of the indoor side rail 222 of the lower frame 22. The resin cover materials 6, 7 are provided over the entire length of the lower frame 22 in the extension direction. A more detailed configuration of the resin cover materials 6, 7 of the lower frame 22 will be described later.

[0018] As shown in Fig. 3, the vertical frame 23 arranged on the door end side of the outer door screen 3 has a composite structure in which a resin cover material 232 is attached to the inside surface of the metal frame body 231, which is the frame body main body. Therefore, it has excellent heat insulation and moisture resistance. The resin cover material 232 is arranged on the inside surface of the vertical frame 23, closer to the room than the outer door screen 3 in the closed state. The resin cover material 232 has an angle part 2321 integrally formed therewith, which protrudes further inside the room than the inside end part 231a of the metal frame body 231. The resin cover material 232 is provided over the entire length of the vertical frame 23 in the extension direction.

[0019] As shown in Fig. 3, the vertical frame 24 arranged on the door end side of the inner shoji 4 has a composite structure in which a resin cover material 242 is attached to the inner surface of a metal frame body 241, which is the frame body main body. Therefore, it has excellent heat insulation and moisture resistance. The resin cover material 242 is arranged on the inner surface of the vertical frame 24, closer to the interior than the inner shoji 4 in the closed state. The resin cover material 242 has an angle portion 2421 integral with it that protrudes further inside the room than the interior end portion 211a of the metal frame body 241. The resin cover material 242 is provided over the entire length of the vertical frame 24 in the extension direction.

[0020] Next, the resin cover materials 6, 7 of the lower frame 22 will be described in further detail with reference to FIG. 4. The resin cover materials 6, 7 are each composed of a plurality of resin cover members. In detail, the resin cover material 6 is composed of two cover members 61, 62 arranged along the projection direction. The resin cover material 7 is composed of two cover members 71, 72 arranged along the projection direction.

[0021] Of the two cover members 61, 62 constituting the resin cover material 6, the cover member 61 arranged on the outdoor side has a vertical cover portion 611 extending along the indoor side surface 221a of the outdoor rail 221, a horizontal cover portion 612 extending integrally from the midpoint of the vertical cover portion 611 toward the indoor side, and a leg portion 613 extending from the indoor end of the horizontal cover portion 612 toward the inner surface 224a of the outdoor metal frame body 2241 in approximately parallel to the vertical cover portion 611. The upper end portion 221b of the outdoor rail 221 protrudes slightly toward the indoor side. The upper end portion 611a of the vertical cover portion 611 abuts against the upper end portion 221b of the outdoor rail 221 from the indoor side. The lower end portion 611b of the vertical cover portion 611 and the leg portion 613 are placed on the inner surface 224a.

[0022] Of the two cover members 61, 62 constituting the resin cover material 6, the cover member 62 arranged on the indoor side has a lateral cover portion 621 arranged along the lateral cover portion 612 of the cover member 61, and a leg portion 622 extending from a midway portion of the lateral cover portion 621 in the projection direction toward the inner surface 224a of the outdoor metal frame body 2241. In the inner surface 224a of the outdoor metal frame body 2241, an engagement groove 224b opening toward the outdoor side is provided near the resin connecting material 2243 over the entire length in the extension direction of the lower frame 22. The lower end portion 622a of the leg portion 622 engages with this engagement groove 224b from the outdoor side.

[0023] The side cover portion 621 of the cover member 62 is arranged so as to overlap with the upper surface of the side cover portion 612 of the cover member 61 with a predetermined overlapping space L1. In this way, the resin cover material 6 is attached so as to cover the inner surface 224a of the outdoor metal frame 2241. The side cover portions 612, 621 may be fixed together by a fixing member such as double-sided adhesive tape (not shown) at the overlapping portions, i.e., within the range of the overlapping space L1, to be integrated together.

[0024] Of the two cover members 71, 72 constituting the resin cover material 7, the cover member 71 arranged on the outdoor side has a vertical cover portion 711 extending along the indoor side surface 222a of the indoor rail 222, a horizontal cover portion 712 extending integrally from the vertical cover portion 711 toward the indoor side, and a leg portion 713 extending from the middle of the horizontal cover portion 712 in the projected direction toward the inner surface 224c of the indoor metal frame body 2242. The upper end portion 222b of the indoor rail 222 protrudes slightly toward the indoor side. The upper end portion 711a of the vertical cover portion 711 of the cover member 71 abuts against the upper end portion 222b of the indoor rail 222 from the indoor side. The leg portion 713 of the cover member 71 is placed on the inner surface 224c.

[0025] Of the two cover members 71, 72 constituting the resin cover material 7, the cover member 72 arranged on the indoor side has a lateral cover portion 721 arranged along the lateral cover portion 712 of the cover member 71, a leg portion 722 extending from the middle of the lateral cover portion 721 in the projected direction toward the inner surface 224c of the indoor metal frame body 2242, and an angle portion 723 protruding toward the indoor side in continuation with the lateral cover portion 721. The indoor side end portion 224d of the indoor metal frame body 2242 has a vertical wall portion 224e extending upward approximately parallel to the indoor rail 222. The angle portion 723 protrudes toward the indoor side beyond the vertical wall portion 224e. At the lower end portion of the vertical wall portion 224e, an engagement protrusion 224f protruding toward the outdoor side is provided over the entire length of the extension direction of the lower frame 22. The cover member 72 has an engaging claw piece 724 that engages with the engaging protrusion 224f.

[0026] The lateral cover portion 721 of the cover member 72 is disposed so as to overlap with the upper surface of the lateral cover portion 712 of the cover member 71 with a predetermined overlapping space L2. In this way, the resin cover material 7 is attached so as to cover the inner surface 224c of the indoor side metal frame body 2242. The lateral cover portions 712, 721 may be fixed together by a fixing member such as double-sided adhesive tape (not shown) at the overlapping portions, i.e., within the range of the overlapping space L2, to be integrated with each other.

[0027] In this way, the resin cover materials 6, 7 covering the metal frame body 224 of the lower frame 22 are composed of multiple cover members 61, 62, 71, 72 that overlap each other with overlapping margins L1, L2, respectively. Therefore, by appropriately adjusting the overlapping margins between the overlapping cover members 61, 62 and between the overlapping cover members 71, 72, the expected dimensions of the resin cover materials 6, 7 can be easily adjusted.

[0028] For example, Fig. 5 shows a lower frame 22A having a larger projection dimension than the lower frame 22 shown in Fig. 2 and Fig. 4. Parts with the same reference numerals as in Fig. 4 show parts with the same configuration. The projection distance W11 between the outdoor side rail 221 and the indoor side rail 222 of this lower frame 22A and the projection distance W12 between the indoor side rail 222 and the standing wall portion 224e are larger than the projection distance W1 between the outdoor side rail 221 and the indoor side rail 222 of the lower frame 22 shown in Fig. 4 and the projection distance W2 between the indoor side rail 222 and the standing wall portion 224e.

[0029] The resin cover materials 6, 7 of the lower frame 22A shown in Fig. 5 are the same as the resin cover materials 6, 7 of the lower frame 22 shown in Fig. 4. The overlapping amount L11 between the lateral cover portions 612, 621 of the resin cover material 6 in the lower frame 22A is smaller than the overlapping amount L1 between the lateral cover portions 612, 621 of the resin cover material 6 in the lower frame 22 shown in Fig. 4 because the distance W11 is larger. The overlapping amount L12 between the lateral cover portions 712, 721 of the resin cover material 7 in the lower frame 22A is smaller than the overlapping amount L2 between the lateral cover portions 712, 721 of the resin cover material 7 in the lower frame 22 shown in Fig. 4 because the distance W12 is larger. The side cover portions 612, 621 and the side cover portions 712, 721 of the resin cover materials 6, 7 in the lower frame 22A may be fixed together in the overlapping areas, i.e., within the range of overlapping margins L11, L12, by a fixing member such as double-sided adhesive tape (not shown).

[0030] In this way, the resin cover material 6, 7 is composed of a plurality of cover members 61, 62, 71, 72 that overlap each other with overlapping margins L1, L2, L11, L12 along the projection direction of the frame body 2. As a result, even if the projection dimension of the lower frame 22A shown in FIG. 5 is larger than that of the lower frame 22 shown in FIG. 4, it is possible to cover the metal frame body 224 of the lower frame 22A using the same resin cover material 6, 7 as the lower frame 22 by appropriately adjusting the overlapping margins of the overlapping cover members 61, 62 and the cover members 71, 72. Therefore, the resin cover material 6, 7 is highly versatile. Therefore, it is not necessary to prepare a plurality of types of resin cover materials for each projection dimension of the frame body 2.

[0031] When multiple cover members 61, 62, 71, 72 are fixed together within the overlapping areas L1, L2, L11, L12 using a fixing member such as double-sided adhesive tape, the resin cover materials 6, 7 are able to cover the metal frame 224 without the cover members 61, 62, 71, 72 shifting.

[0032] The frame body of the bottom frame 22 of the sliding window 1 of this embodiment is composed of a metal frame 224. The bottom frame 22 has resin cover materials 6, 7 superimposed on the inner surface of the metal frame 224, so that the sliding window 1 can have high thermal insulation performance and moisture prevention performance.

[0033] The resin cover materials 6 and 7 shown in this embodiment are respectively formed by two cover members 61, 62, 71, 72 overlapping each other, but the number of cover members constituting the resin cover materials 6 and 7 is not limited to two. The resin cover materials 6 and 7 may each be formed by three or more cover members overlapping each other.

[0034] The resin cover material composed of a plurality of cover members is not limited to that provided on the lower frame 22. The resin cover materials 245, 216 of the upper frame 21 and the resin cover materials 232, 242 of the vertical frames 23, 24 may also be composed of a plurality of cover members arranged along the projection direction of the frame body 2 and overlapping each other with an overlapping margin, similar to the above.

[0035] In this embodiment, a sliding window 1 is shown as the fitting. However, the configuration described above is not limited to sliding windows, and can be widely applied to fittings that are configured by fitting a paper screen into a frame. [Explanation of symbols]
