[Modes for carrying out the invention]

[0007] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. A sliding window 1 constituting a building component of one embodiment will be described. In this specification, "face direction" means the direction of the surfaces of the facing materials 35, 45 in the sliding window 1 fitted into an opening formed in the wall of a building, and "depth direction" means the thickness direction (i.e., depth direction) of the facing materials 35, 45. The "depth direction" is also the interior-exterior direction. "Face surface" means the respective surfaces of the sliding window 1 that face the exterior and interior sides, and "depth surface" means the surface of the sliding window 1 that extends in the interior-exterior direction. In the drawings, the exterior side of the sliding window 1 is referred to as the exterior side X1, and the interior side of the sliding window 1 is referred to as the interior side X2.

[0008] As shown in Figures 1 to 3, the sliding window 1 is constructed by installing a frame 2 into an opening in a building structure (not shown), and housing inside the frame 2 two sashes: an outer sash 3 (sash) positioned on the exterior side X1 and an inner sash 4 (sash) positioned on the interior side X2, as well as a single screen door 51 positioned on the exterior side X1 of the outer sash 3. The outer sash 3 and inner sash 4 are slidable within the frame 2 in the left-right direction (horizontal direction) of the visible side.

[0009] The frame 2 is constructed 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. As shown in Figure 2, the upper frame 21 is provided with an outdoor rail 211 and an indoor rail 212. The upper frame 21 has a screen door rail 213 on the outdoor side X1 of the outdoor rail 211. The outdoor rail 211 is formed to protrude downward from the upper frame 21 on the outdoor side X1 of the upper frame 21 and guides the upper end of the outer sash 3. The indoor rail 212 is formed to protrude downward from the upper frame 21 on the indoor side X2 of the upper frame 21 and guides the upper end of the inner sash 4.

[0010] The lower frame 22 is provided with an outdoor rail 221 and an indoor rail 222. The lower frame 22 has a screen door rail 223 on the outdoor side X1 of the outdoor rail 221.

[0011] The screen door 51 is engaged with the screen door rails 213 and 223 of the upper frame 21 and lower frame 22 so as to be movable in the left-right direction.

[0012] As shown in Figures 1 to 3, the outer sliding door 3 is constructed by assembling an upper frame 31, a lower frame 32, a vertical frame 33 positioned on the leading edge side, and an outer meeting frame 34 (a vertical frame positioned on the trailing edge side) into a rectangular frame body 30, and housing a facing material 35 made of two panes of glass inside this frame. The outer sliding door 3 is engaged with the outdoor rails 211 and 221 of the upper frame 21 and lower frame 22 so as to be movable in the left-right direction. The lower frame 32 of the outer sliding door 3 is provided with a roller 36 that rolls on the outdoor rail 221 of the lower frame 22.

[0013] The inner shutter 4 is composed of a frame body 40 formed by rectangularly framing an upper frame 41, a lower frame 42, a vertical frame 43 arranged on the door tip side, and an inner mating frame 44 (vertical member) arranged on the door butt side, and a facing material 45 composed of two pieces of glass is housed inside. The inner shutter 4 is engaged with the indoor side rails 212 and 222 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction. A door wheel 46 that rolls on the indoor side rail 222 of the lower frame 22 is provided on the lower frame 42 of the inner shutter 4.

[0014] As shown in FIGS. 2 and 3, the upper frame 31, the lower frame 32, the vertical frame 33 arranged on the door tip side, and the outer mating frame 34 (vertical member) of the outer shutter 3 each have a composite structure in which resin frame materials 312, 322, 332, and 342 are attached to the indoor side X2 of the metal frame materials 311, 321, 331, and 341. The upper frame 41, the lower frame 42, the vertical frame 43 arranged on the door tip side, and the inner mating frame 44 of the inner shutter 4 each have a composite structure in which resin frame materials 412, 422, 432, and 442 are attached to the indoor side X2 of the metal frame materials 411, 421, 431, and 441.

[0015] In this embodiment, for example, the metal frame materials 411, 421, 431, and 441 are formed of an aluminum material, and the frames of the outer shutter 3 (the upper frame 31, the lower frame 32, the vertical frame 33 arranged on the door tip side, and the outer mating frame 34) and the frames of the inner shutter 4 (the upper frame 41, the lower frame 42, the vertical frame 43 arranged on the door tip side, and the inner mating frame 44) are composed of an aluminum-resin composite structure. As a result, the outer shutter 3 and the inner shutter 4 are excellent in heat insulation and dew prevention properties.

[0016] As described above, the frame body 30 of the outer shutter 3 is formed by rectangularly framing the upper frame 31, the lower frame 32, the vertical frame 33 arranged on the door tip side, and the outer mating frame 34 which is a vertical frame arranged on the door butt side, and the upper frame 31 and the lower frame 32 of the outer shutter 3 each have a composite structure in which resin-made resin frame materials 312 and 322 (horizontal members) are attached to the indoor side X2 of the metal frame materials 311 and 321.

[0017] The combination of the outside call assembly frame 34 and the upper frame 31, and the combination of the outside call assembly frame 34 and the lower frame 32 are combined in a so-called vertical win structure where the upper end portion of the outside call assembly frame 34 is disposed outside the lateral end portion of the upper frame 31 and the lower end portion of the outside call assembly frame 34 is disposed outside the lateral end portion of the lower frame 32, as shown in FIGS. 4 to 7.

[0018] In the outer shutter 3, when assembling the upper frame 31 to the upper end portion of the outside call assembly frame 34 or when assembling the lower frame 32 to the lower end portion of the outside call assembly frame 34, a part of the lateral end portion of the upper frame 31 (metal frame material 311, resin frame material 312) or a part of the lateral end portion of the lower frame 32 (metal frame material 321, resin frame material 322) is inserted into the inside of the upper end portion or the lower end portion of the outside call assembly frame 34 for assembly.

[0019] As described above, the frame body 40 of the inner shutter 4 is formed by frame-assembling an upper frame 41, a lower frame 42, a vertical frame 43 disposed on the door tip side, and an inside call assembly frame 44 which is a vertical frame disposed on the door butt side into a rectangle. Further, the upper frame 41 and the lower frame 42 of the inner shutter 4 each have a composite structure in which resin-made resin frame materials 412, 422 (horizontal members) are attached to the indoor side X2 of the metal frame materials 411, 421.

[0020] The combination of the inside call assembly frame 44 and the upper frame 41, and the combination of the inside call assembly frame 44 and the lower frame 42 are combined in a so-called vertical win structure where the upper end portion of the inside call assembly frame 44 is disposed outside the lateral end portion of the upper frame 41 and the lower end portion of the inside call assembly frame 44 is disposed outside the lateral end portion of the lower frame 42, as shown in FIGS. 4 to 7.

[0021] In the inner shutter 4, when assembling the upper frame 41 to the upper end portion of the inside call assembly frame 44 or when assembling the lower frame 42 to the lower end portion of the inside call assembly frame 44, a part of the lateral end portion of the upper frame 41 (metal frame material 411, resin frame material 412) or a part of the lateral end portion of the lower frame 42 (metal frame material 421, resin frame material 422) is inserted into the inside of the upper end portion or the lower end portion of the inside call assembly frame 44 for assembly.

[0022] Here, we compare the lower frame 32 of the outer sash 3 and the lower frame 42 of the inner sash 4. In this embodiment, as shown in Figure 3, the length L1 in the left-right direction (longitudinal direction) of the resin frame material 322 of the lower frame 32 of the outer sash 3 and the length L1 in the left-right direction (longitudinal direction) of the resin frame material 422 of the lower frame 42 of the inner sash 4 are formed to be the same length. As a result, the resin frame material 322 of the lower frame 32 of the outer sash 3 and the resin frame material 422 of the lower frame 42 of the inner sash 4 can be made common, thereby reducing manufacturing costs and preventing errors during manufacturing.

[0023] In the outer sliding door 3, as shown in Figures 3 and 7, a gap S62 is formed between the resin frame material 322 of the lower frame 32 of the outer sliding door 3 and the outer meeting frame 34. As shown in Figure 3, the length of the gap S62 between the resin frame material 322 of the lower frame 32 of the outer sliding door 3 and the outer meeting frame 34 in the left-right direction is L21.

[0024] Furthermore, in the inner sliding door 4, as shown in Figures 3 and 7, a gap S72 is formed between the resin frame material 422 of the lower frame 42 of the inner sliding door 4 and the inner meeting frame 44. As shown in Figure 3, the length of the gap S72 in the left-right direction between the resin frame material 422 of the lower frame 42 of the inner sliding door 4 and the inner meeting frame 44 is L22.

[0025] Furthermore, the upper frame 31 of the outer shoji screen 3 and the upper frame 41 of the inner shoji screen 4 are compared here. In this embodiment, although not shown in the illustration, similar to the lower frame 32 of the outer shoji screen 3 and the lower frame 42 of the inner shoji screen 4, the length of the resin frame material 312 of the upper frame 31 of the outer shoji screen 3 in the left-right direction (longitudinal direction) and the length of the resin frame material 412 of the upper frame 41 of the inner shoji screen 4 are formed to be the same length. As a result, the resin frame material 312 of the upper frame 31 of the outer shoji screen 3 and the resin frame material 412 of the upper frame 41 of the inner shoji screen 4 can be made common, thereby reducing manufacturing costs and preventing errors during manufacturing.

[0026] In the upper frame 31 of the outer shoji screen 3 and the upper frame 41 of the inner shoji screen 4, as shown in Figures 5, 8, and 10, a gap S61 is formed between the resin frame material 312 of the upper frame 31 of the outer shoji screen 3 and the outer meeting frame 34. Similarly, a gap S71 is formed between the resin frame material 412 of the upper frame 41 of the inner shoji screen 4 and the inner meeting frame 44.

[0027] Next, we will explain the upper end cap 61 (end cap) attached to the upper end of the outer meeting frame 34 of the outer shoji screen 3, and the lower end cap 62 (end cap) attached to the lower end of the outer meeting frame 34 of the outer shoji screen 3. The upper end cap 61 is attached to the upper end of the outer meeting frame 34 of the outer shoji screen 3, with the outer meeting frame 34 and the upper frame 31 assembled together. The lower end cap 62 is attached to the lower end of the outer meeting frame 34 of the outer shoji screen 3.

[0028] The upper end cap 61 covers the upper end of the outer meeting stile 34 and seals the gap S61 between the resin frame material 342 of the outer meeting stile 34 and the upper stile 31. The upper end cap 61 is formed by integrating the cap body 611 and the gap-sealing portion 612.

[0029] As shown in Figures 4, 5, and 8, the gap-filling portion 612 has an extended upper plate 612a extending from the upper surface of the cap body 611 toward the upper frame 31, and a vertical plate 612b extending downward from the end of the extended upper plate 612a toward the upper frame 31. This allows the cap body 611 to cover the upper end of the outer meeting frame 34, and the gap-filling portion 612, having the extended upper plate 612a and the vertical plate 612b, to fill the gap S61 between the outer meeting frame 34 and the resin frame material 312 of the upper frame 31. The length of the extended upper plate 612a of the gap-filling portion 612 is appropriately set according to the size of the gap S61 between the outer meeting frame 34 and the resin frame material 312 of the upper frame 31.

[0030] The lower end cap 62 covers the lower end of the outer meeting stile 34 and seals the gap S62 between the resin frame material 342 of the outer meeting stile 34 and the lower stile 32. The lower end cap 62 is formed by integrating the cap body 621 and the gap-sealing portion 622.

[0031] As shown in Figures 6, 7, and 9, the gap-filling portion 622 has an extended bottom plate 622a extending from the lower surface of the cap body 621 toward the bottom frame 32, and a vertical plate 622b extending upward from the end of the extended bottom plate 622a toward the bottom frame 32. This allows the cap body 621 to cover the lower end of the outer meeting frame 34, and the gap-filling portion 622, having the extended bottom plate 622a and the vertical plate 622b, to fill the gap S62 between the outer meeting frame 34 and the resin frame material 322 of the bottom frame 32. The length of the extended bottom plate 622a of the gap-filling portion 622 is appropriately set according to the size of the gap S62 between the outer meeting frame 34 and the resin frame material 322 of the bottom frame 32.

[0032] Next, we will explain the upper end cap 71 (end cap) attached to the upper end of the inner meeting stile 44 of the inner shoji screen 4, and the lower end cap 72 (end cap) attached to the lower end of the inner meeting stile 44 of the inner shoji screen 4. The upper end cap 71 is attached to the upper end of the inner meeting stile 44 of the inner shoji screen 4, with the inner meeting stile 44 and the upper stile 41 assembled together. The lower end cap 72 is attached to the lower end of the inner meeting stile 44 of the inner shoji screen 4.

[0033] The upper end cap 71 covers the upper end of the inner meeting stile 44 and seals the gap S71 between the resin stile material 442 of the inner meeting stile 44 and the upper stile 41. The upper end cap 71 is formed by integrating the cap body 711 and the gap-sealing portion 712.

[0034] As shown in Figures 4, 5, and 10, the gap-filling portion 712 has an extended top plate 712a extending from the upper surface of the cap body 711 toward the upper frame 41, and a vertical plate 712b extending downward from the end of the extended top plate 712a toward the upper frame 41. This allows the cap body 711 to cover the upper end of the inner meeting frame 44, and the gap-filling portion 712, having the extended top plate 712a and the vertical plate 712b, to fill the gap S71 between the inner meeting frame 44 and the resin frame material 412 of the upper frame 41. The length of the extended top plate 712a of the gap-filling portion 712 is appropriately set according to the size of the gap S71 between the inner meeting frame 44 and the resin frame material 412 of the upper frame 41.

[0035] The lower end cap 72 covers the lower end of the inner meeting frame 44 and seals the gap S72 between the resin frame material 442 of the inner meeting frame 44 and the lower frame 42. The lower end cap 72 is formed by integrating the cap body 721 and the gap-sealing portion 722.

[0036] As shown in Figures 6, 7, and 11, the gap-filling portion 722 has an extended lower plate 722a extending from the upper surface of the cap body 721 toward the lower frame 42, and a vertical plate 722b extending upward from the end of the extended lower plate 722a toward the lower frame 42. This allows the cap body 721 to cover the lower end of the inner meeting frame 44, and the gap-filling portion 722, having the extended lower plate 722a and the vertical plate 722b, to fill the gap S72 between the inner meeting frame 44 and the resin frame material 422 of the lower frame 42. The length of the extended lower plate 722a of the gap-filling portion 722 is appropriately set according to the size of the gap S72 between the inner meeting frame 44 and the resin frame material 422 of the lower frame 42.

[0037] Traditionally, the joint between the horizontal resin frame and the vertical frame was not visible during the use of the door, and a gap sometimes formed between the horizontal resin frame and the vertical frame. However, this allowed cold air to enter, leading to a decrease in insulation performance.

[0038] In contrast, in this disclosure, gap-filling portions 612, 622, 712, and 722 fill the gaps S61, S62, S71, and S72 between the vertical members (outer meeting frame 34, inner meeting frame 44) and the horizontal members (resin frame material 312, 322, 412, and 422). This improves the thermal insulation performance.

[0039] Furthermore, in some cases, the dimensions of the resin components of the horizontal frames are adjusted to prevent gaps from forming between the horizontal and vertical frames. However, in such cases, the internal shape of the outer meeting frame of the outer shoji screen differs from that of the inner meeting frame of the inner shoji screen, requiring different dimension settings for the outer and inner shoji screens. In such cases, however, it was not possible to standardize the resin components, which contributed to increased manufacturing costs and the possibility of manufacturing errors.

[0040] In contrast, in this disclosure, the left-right lengths of the resin frame materials 312, 322 of the horizontal frames (upper frame 31, lower frame 32) of the outer sash 3 and the left-right lengths of the resin frame materials 412, 422 of the horizontal frames (upper frame 41, lower frame 42) of the inner sash 4 are made the same, while the gaps S61, S62, S71, S72 between the vertical members (outer meeting frame 34, inner meeting frame 44) and the horizontal members (resin frame materials 312, 322, 412, 422) are sealed by gap-sealing parts 612, 622, 712, 722. Therefore, by sealing the gaps S61, S62, S71, S72 with gap-sealing parts 612, 622, 712, 722, the thermal insulation performance can be improved.

[0041] As a result, even if the gaps S61, S62, S71, S72 between the vertical members (outer meeting frame 34, inner meeting frame 44) and the horizontal members (resin frame material 312, 322, 412, 422) are of different sizes, the gaps can be sealed by the gap-sealing parts 612, 622, 712, 722. Therefore, the horizontal members (resin frame material 312, 322) of the outer sash 3 and the horizontal members (resin frame material 412, 422) of the inner sash 4 can be made common while improving the thermal insulation performance.

[0042] Furthermore, in this embodiment, the gap-filling portions 612, 622, 712, and 722 are formed integrally with the end caps (upper end cap 61, lower end cap 62, upper end cap 71, and lower end cap 72) of the vertical members (outer meeting frame 34 and inner meeting frame 44). By integrating the gap-filling portions 612, 622, 712, and 722 with the end caps (upper end cap 61, lower end cap 62, upper end cap 71, and lower end cap 72), it is not necessary to provide new gap-filling portions. This reduces manufacturing costs.

[0043] Furthermore, in this embodiment, the horizontal members (resin frame materials 312, 322) of the outer sash 3 and the horizontal members (resin frame materials 412, 422) of the inner sash 4 have the same length in the longitudinal direction. This allows the horizontal members (resin frame materials 312, 322) of the outer sash 3 and the inner sash 4 to be standardized. This reduces manufacturing costs.

[0044] While a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the embodiment described above and can be modified as appropriate.

[0045] In the above embodiment, the gap-filling portions 612, 622, 712, and 722 were formed by integrating them with the end caps (upper end cap 61, lower end cap 62, upper end cap 71, and lower end cap 72) of the vertical members (outer meeting frame 34 and inner meeting frame 44). However, the embodiment is not limited to this, and they may be formed separately. [Explanation of Symbols]
