Summary of the Invention

Problems to be Solved by the Invention

[0004] Fittings in which the main structural material is made of a non-metallic material as in Patent Documents 1 and 2 have a problem that it is difficult to cope with the knockdown method of assembling the frame members and panels at the construction site. The heat insulating shoji of Patent Document 1 requires assembling a rectangular outdoor aluminum frame assembly with aluminum frame members, assembling a rectangular indoor wooden frame assembly with wooden frame members, and fitting the concave portion of the outdoor aluminum frame assembly and the convex portion of the indoor wooden frame assembly with a panel interposed therebetween to assemble the heat insulating shoji. For this reason, the assembly process becomes numerous, and since it is necessary to perform fitting and joining while positioning the rectangular assemblies, it was difficult to assemble at the construction site. The shoji screen described in Patent Document 2 requires welding equipment because the ends of the resin frame material are joined by welding, making it impossible to assemble it at the construction site.

[0005] The objective of the present invention is to provide a building component that can improve assembly workability and is compatible with knockdown systems. [Means for solving the problem]

[0006] The joinery of the present invention is a joinery framed with vertical members and horizontal members, at least in part of which are made of non-metallic material, wherein metal vertical connecting members are attached to both ends in the longitudinal direction of the vertical members, and metal horizontal connecting members are attached to both ends in the longitudinal direction of the horizontal members, and the vertical members and horizontal members are connected by fastening members connecting the vertical connecting members and the horizontal connecting members. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide building components that can be assembled with improved workability and are compatible with knockdown systems. [Brief explanation of the drawing]

In the exterior meeting stile 24, a glass retaining groove is formed between the inner circumferential end of the exterior surface portion 341 of the exterior member 34 and the retaining piece portion 443 of the interior member 44, with the panel 26 positioned via a gasket 27. In the interior meeting stile 25, a glass retaining groove is formed between the inner circumferential end of the exterior surface portion 351 of the exterior member 35 and the retaining piece portion 453 of the interior member 45, with the panel 26 positioned via a gasket 27.

[0025] As mentioned above, reinforcing members 51 are attached to the glass retaining grooves of the upper frame 21, lower frame 22, door edge frame 23, and outer meeting frame 24. In addition, the fixing piece 352 of the exterior member 35 and the reinforcing member 52 are attached to the glass retaining groove of the inner meeting frame 25. Furthermore, although the panel 26 in this embodiment is made of double-glazed glass, triple-glazed glass or the like may also be used.

[0026] Here, as shown in Figure 1, the reinforcing member 51 is formed in a substantially L-shape in cross-section and comprises a fixed surface portion 511 fixed to the main body portions 411, 421, 431, and 441 with screws 61, a clamping piece portion 512 extending from the outdoor edge of the fixed surface portion 511 toward the outer circumference of each sash, and a holding piece portion 513 extending from the indoor edge of the fixed surface portion 511 toward the inner circumference of each sash. The clamping piece portion 512 is the part that clamps the engaging pieces 313, 323, 333, and 343 of the outdoor members 31, 32, 33, and 344 between itself and the main body portions 411, 421, 431, and 441. As shown in Figure 2, the reinforcing member 52 is formed in a substantially L-shape in cross-section, comprising a fixed surface portion 521 fixed to the main body portion 451 and a retaining piece portion 523 extending from the indoor side edge of the fixed surface portion 521 along the retaining piece portion 453. The fixed surface portion 521 of the reinforcing member 52 is positioned away in the depth direction so as not to directly contact the outdoor surface portion 351 of the outdoor member 35, thereby creating a gap between the outdoor member 35 and the reinforcing member 52, which improves the thermal insulation performance. The materials of the reinforcing members 51 and 52 can be, for example, aluminum, iron, stainless steel, etc., and these materials can be set as appropriate during implementation. In this embodiment, stainless steel reinforcing members 51 and 52 are used, taking thermal insulation into consideration.

[0027] In this embodiment, the reinforcing members 51 and 52 are long members that are continuous along the longitudinal direction of the upper frame 21, lower frame 22, door edge frame 23, outer meeting frame 24, and inner meeting frame 25, but multiple short pieces may be arranged along the longitudinal direction. The retaining pieces 513 and 523 of the reinforcing members 51 and 52 are fixed to the interior surface of the retaining pieces 413, 423, 433, 443, and 453 with adhesive or double-sided tape, and are positioned between the gasket 27 and the retaining pieces 413, 423, 433, 443, and 453. As a result, the wind pressure applied to the panel 26 can be supported by the metal exterior members 31, 32, 33, 34, and 35, and the metal reinforcing members 51 and 52.

[0028] As shown in Figures 3 to 5, connecting members are attached to both ends in the longitudinal direction of the upper frame 21, lower frame 22, door edge frame 23, and outer meeting frame 24 of the outer sliding door 20A. Specifically, metal horizontal connecting members 210 and 220 are attached to both the left and right ends of the upper frame 21 and lower frame 22, respectively. In addition, metal vertical connecting members 230 and 240 are attached to both the upper and lower ends of the door edge frame 23 and outer meeting frame 24, respectively. Metal horizontal connecting members 210 and 220 are attached to the left and right ends of the upper frame 21 and lower frame 22 of the inner sliding door 20B, respectively. In addition, metal vertical connecting members 230 and 250 are attached to the upper and lower ends of the door frame 23 and inner meeting frame 25, respectively.

[0029] As shown in Figures 3 and 6, in the upper frame 21, the left and right ends of the main body portion 411 of the interior member 41 are cut out on the upper side, and the lateral connecting member 210 is attached to this cut-out portion. In the exterior member 31, the left and right ends of the fixing piece portion 314, for example, which would interfere with the lateral connecting member 210, are cut out. In addition, both the left and right ends of the exterior surface portion 311 are cut out in a rectangular shape so as not to interfere with the vertical connecting members 230, 240, and 250, which will be described later. The lateral connecting member 210 comprises a connecting reinforcing portion 211, an engaging piece portion 212, and a fixing piece portion 213. The connecting reinforcing portion 211 comprises a bottom surface portion, a reinforcing piece portion extending upward from the indoor end of the bottom surface portion along the indoor member 41, and an extending piece portion extending upward from the outdoor end of the bottom surface portion and arranged parallel to the reinforcing piece portion, and is formed in a substantially U-shape cross-section with an open top. The engaging piece portion 212 extends outward from the bottom surface portion of the connecting reinforcing portion 211 and engages with the engaging piece portion 313. The fixing piece portion 213 extends outward from the upper end of the extending piece portion of the connecting reinforcing portion 211 and engages with the engaging piece portion 313, and is fixed to the outdoor member 31 with a screw 62. The connecting reinforcement portion 211 of the lateral connecting member 210 is fixed to the interior member 41 with adhesive or double-sided tape. In addition, an upper sliding piece (not shown) is attached to the lateral connecting member 210 as a functional component. The end of the lateral connecting member 210 protrudes beyond the interior member 41, and this protruding portion abuts against the vertical connecting members 230, 240, and 250, and is connected to the vertical connecting members 230, 240, and 250 by screws 65, which are fastening members.

[0030] As shown in Figures 3 and 7, in the lower frame 22, the left and right ends of the main body portion 421 of the indoor member 42 are cut out on the lower side, and the lateral connecting members 220 are attached to these cut-out portions. In the outdoor member 32, portions that interfere with the lateral connecting members 220, such as the left and right ends of the fixing piece portion 324, are cut out. In addition, both the left and right ends of the outdoor surface portion 321 are cut out in a rectangular shape so as not to interfere with the vertical connecting members 230, 240, and 250. The lateral connecting member 220 comprises a connecting reinforcing portion 221, an engaging piece portion 222, and a fixing piece portion 223. The connecting reinforcing portion 221 comprises an upper surface portion, a reinforcing piece portion extending downward from the indoor end of the upper surface portion along the indoor member 42, and an extending piece portion extending downward from the outdoor end of the upper surface portion and arranged parallel to the reinforcing piece portion, and is formed in a substantially U-shape cross-section with an open bottom. The engaging piece portion 222 extends outward from the upper surface portion of the connecting reinforcing portion 221 and engages with the engaging piece portion 323. The fixing piece portion 223 extends outward from the vertically intermediate portion of the extending piece portion of the connecting reinforcing portion 221 and engages with the engaging piece portion 313, and is fixed to the outdoor member 32 with a screw 62. The only difference between the lateral connecting member 220 and the lateral connecting member 210 is that the vertical dimension of the connecting reinforcement portion 221 is larger than that of the connecting reinforcement portion 211. Therefore, by cutting off a portion of the reinforcing piece and the extended piece of the lateral connecting member 220, it can be converted into the lateral connecting member 210. The connecting reinforcement portion 221 of the lateral connecting member 220 is fixed to the interior member 42 with adhesive or double-sided tape. In addition, a door roller 280 and a lower sliding piece 290 are attached to the lateral connecting member 220 as functional components. The end of the lateral connecting member 220 protrudes beyond the interior member 42, and this protruding portion abuts against the vertical connecting members 230, 240, and 250, and is connected to the vertical connecting members 230, 240, and 250 by screws 65, which are fastening members.

[0031] As shown in Figures 4 and 7, in the door frame 23, the upper and lower ends of the main body 431 of the interior member 43 are cut out on the exterior side, and the vertical connecting member 230 is attached to this cut-out portion. The vertical connecting member 230 comprises an outdoor surface portion 231, a first visible surface portion 232, a second visible surface portion 233, and an indoor surface portion 234, and is formed in a roughly rectangular tubular shape in plan view. The first visible surface portion 232 is the outer surface facing the vertical frames 13 and 14, and the fixing piece portion 334 of the outdoor member 33 is fixed to it with screws 62. The second visible surface portion 233 is the surface facing the glass holding groove, and the reinforcing member 51 is fixed to it with screws 62. Furthermore, the outdoor end of the second visible surface portion 233 is bent into a roughly L-shape, and the engaging piece portion 333 of the outdoor member 33 is engaged between this bent portion and the outdoor surface portion 231. Furthermore, the upper and lower ends of the clamping piece 512 of the reinforcing member 51 fixed to the second visible surface portion 233 have been cut off to avoid interference with the vertical connecting member 230. In addition, the upper and lower ends of the fixing piece 334 of the outdoor member 33 have been cut off so as not to interfere with the horizontal connecting member 210 and the horizontal connecting member 220. For this reason, the vertical dimension of the fixing piece 334 is shorter than the vertical dimension of the outdoor surface portion 331. The interior surface portion 234 is provided along the interior member 43, and the intermediate portion in the left-right direction is a connecting portion 235 that is bent into a planar U shape, and screw holes are formed in this connecting portion 235. The vertical connecting member 230 is fixed to the interior member 43 with adhesive or double-sided tape, and further fixed to the exterior member 33 and the reinforcing member 51 with screws 62, thereby being attached to the upper and lower ends of the door frame 23. The vertical end faces of the vertical connecting member 230 are in contact with the horizontal connecting members 210 and 220. The vertical connecting member 230 and the horizontal connecting members 210 and 220 are then connected by screws 65, which are fastening members that are screwed into the screw holes of the vertical connecting member 230 through through holes in the connecting reinforcing parts 211 and 221 of the horizontal connecting members 210 and 220.

[0032] As shown in Figures 4 and 6, in the exterior meeting stile 24, the upper and lower ends of the main body portion 441 of the interior member 44 are cut out on the exterior side, and the vertical connecting member 240 is attached to this cut-out portion. The vertical connecting member 240 has the same structure as the vertical connecting member 230, so the same reference numeral is used and its description is omitted. In addition, the clamping piece portion 512 of the reinforcing member 51 fixed to the second visible surface portion 233 of the vertical connecting member 240 has both the upper and lower ends cut off to avoid interference with the vertical connecting member 240, just like the reinforcing member 51 of the door frame 23. Furthermore, grooves are machined into the upper and lower ends of the side covering portion 342 of the exterior member 34 so as not to interfere with the exterior rails 115, 125 and the interior rails 116, 126. The vertical connecting member 240 is fixed to the interior member 44 with adhesive or double-sided tape, and further fixed to the exterior member 34 and the reinforcing member 51 with screws 62, thereby being attached to the upper and lower ends of the exterior meeting frame 24. The vertical end faces of the vertical connecting member 240 are in contact with the horizontal connecting members 210 and 220. The vertical connecting member 240 and the horizontal connecting members 210 and 220 are then connected by screws 65, which are fastening members that are screwed into the screw holes of the vertical connecting member 240 through through holes in the connecting reinforcing parts 211 and 221 of the horizontal connecting members 210 and 220.

[0033] As shown in Figure 4, in the interior meeting stile 25, the upper and lower ends of the main body 451 of the interior member 45 are cut out on the exterior side, and the vertical connecting member 250 is attached to this cut-out portion. The vertical connecting member 250 has a shape similar to the vertical connecting members 230 and 240, and comprises an exterior surface portion 251, a first visible surface portion 252, a second visible surface portion 253, and an interior surface portion 254, and is formed in a roughly rectangular tubular shape in plan view. The exterior surface 251 is bent in a crank shape at its midpoint in the left-right direction to match the shape of the interior member 45. The exterior member 35 is fixed to the exterior surface 251 with screws 62. The first visible surface 252 is covered with a wooden cover material 259 fixed with screws 64 so that the first visible surface 252 is not visible from the interior side. The second visible surface 253 is the surface on the glass holding groove side, and the exterior member 35 and the reinforcing material 52 are fixed with screws 62. The interior surface portion 254 is provided along the interior member 45, and the intermediate portion in the left-right direction is a connecting portion 255 that is bent into a planar U shape, and screw holes are formed in this connecting portion 255. The vertical connecting member 250 is fixed to the interior member 45 with adhesive or double-sided tape, and further fixed to the exterior member 35 and reinforcing member 52 with screws 62, thereby being attached to the upper and lower ends of the interior meeting frame 25. The end face of the vertical connecting member 250 abuts against the horizontal connecting members 210 and 220, and the vertical connecting member 250 and the horizontal connecting members 210 and 220 are connected by screws 65, which are fastening members that are screwed into screw holes in the vertical connecting member 250 through through holes in the connecting reinforcing parts 211 and 221 of the horizontal connecting members 210 and 220. Furthermore, the upper and lower ends of the fixing piece 352 of the outdoor member 35 are cut out so as not to interfere with the lateral connecting members 210 and 220, and their vertical dimensions are shorter than those of the outdoor surface 351. In addition, the upper and lower ends of the reinforcing member 52 are set to match the upper and lower ends of the fixing piece 352, and the reinforcing member 52 is also set so as not to interfere with the lateral connecting members 210 and 220.

[0034] Furthermore, the screws 62 that fasten the exterior members 31 and 32 of the upper frame 21 and lower frame 22 to the lateral connecting members 210 and 220 are countersunk screws, and the heads of these screws 62 are exposed on the exterior surface of the exterior members 31 and 32. However, as shown in Figure 5, on the door edge frame 23 side and the outer meeting frame 24 side, the screws 62 are covered by the exterior members 33 and 34, so they are not exposed on the exterior side, improving the aesthetic appearance. Even if the screws 62 are exposed on the exterior side of the inner meeting frame 25, they are hidden by the outer meeting frame 24 of the outer sash 20A, so a decrease in aesthetic appearance is prevented. Therefore, the screws 62 that fasten the lateral connecting members 210 and 220 to the exterior members 31 and 32 of the upper frame 21 and lower frame 22 are second fastening members. Furthermore, in the upper frame 21, lower frame 22, door edge frame 23, and outer meeting frame 24, the aluminum exterior members 31, 32, 33, and 34 are formed in a substantially thin plate shape, and their depth dimensions are small. On the other hand, the main body parts 411, 421, 431, and 441 of the interior members 41, 42, 43, and 44 have larger depth dimensions in the longitudinal intermediate parts other than the ends where the lateral connecting members 210, lateral connecting members 220, and vertical connecting members 230, and 240 are placed. Specifically, the exterior surfaces of the interior members 41, 42, 43, and 44 are positioned on the exterior side of the center of the panel 26 in the depth direction, that is, the midpoint between the two panes of glass. Therefore, in the upper frame 21, lower frame 22, door edge frame 23, and exterior meeting frame 24, the wooden interior members 41, 42, 43, and 44 function as the main structural members, while the exterior members 31, 32, 33, and 31 function as protective materials to prevent the interior members 41, 42, 43, and 44 from being exposed to the outside. Furthermore, in the cross-section perpendicular to the longitudinal direction of the upper frame 21, lower frame 22, door edge frame 23, and exterior meeting frame 24, the area occupied by the wooden interior members 41, 42, 43, and 44 is large, thus improving the thermal insulation performance. Similarly, in the interior meeting frame 25, the interior member 45 becomes the main structural member, thus improving the thermal insulation performance.

[0035] In the first embodiment, the crescent lock 38 was fixed to the interior member 45 of the interior meeting stile 25 with screws. However, as shown in Figure 8, a notch similar to the upper and lower ends may be provided in the middle of the interior member 45 in the vertical direction, and a vertical connecting member 250, which is a metal intermediate member, may be attached to this notch. The crescent lock 38 may then be fixed to this vertical connecting member 250 via a cover material 259. In this case, since the vertical connecting member 250 is provided in the middle of the interior meeting stile 25, the fixing strength of the crescent lock 38 can be improved.

[0036] [Effects of the First Embodiment] According to the first embodiment, horizontal connecting members 210, 220 and vertical connecting members 230, 240, 250 are provided at the ends of the upper frame 21, lower frame 22, door frame 23, outer meeting frame 24, and inner meeting frame 25, which have wooden interior members 41, 42, 43, 44, 45 that are non-metallic as the main structural material. The horizontal connecting members 210, 220 and the vertical connecting members 230, 240, 250 are connected with screws 65 which are fastening members, thereby connecting and assembling the upper frame 21, lower frame 22 and the door frame 23, outer meeting frame 24, and inner meeting frame 25. This improves assembly workability, and the outer shoji screen 20A and inner shoji screen 20B, which are joinery, can be easily assembled at the construction site using a knockdown method. Since the wooden interior members 41, 42, 43, 44, and 45 serve as the main structural members of the upper frame 21, lower frame 22, door edge frame 23, exterior meeting frame 24, and interior meeting frame 25, the thermal insulation performance can be improved. In particular, the intermediate portions in the longitudinal direction of the upper frame 21, lower frame 22, door edge frame 23, exterior meeting frame 24, and interior meeting frame 25 have their exterior surfaces positioned further outward than the intermediate portion in the depth direction of the panel 26, resulting in a larger depth dimension, thus improving thermal insulation performance.

[0037] Since the horizontal connecting members 210, 220 and the vertical connecting members 230, 240, 250 are provided at both ends in the longitudinal direction of the upper frame 21, lower frame 22, door edge frame 23, outer meeting frame 24, and inner meeting frame 25, the processing of the wooden interior members 41, 42, 43, 44, and 45 can be simplified, and processing costs can be reduced. Furthermore, since functional parts such as door rollers 280 and lower sliding pieces 290 are attached to the horizontal connecting members 210 and 220, there is no need to perform special processing on the wooden interior members 41 and 42 to attach the door rollers 280 and lower sliding pieces 290, which also simplifies the processing of the interior members 41 and 42 and reduces costs. In addition, since there is no need to perform complex processing on the interior members 41, 42, 43, 44, and 45, there are no unpainted areas when performing surface preparation or painting, improving quality and reducing processing costs.

[0038] Since the horizontal connecting members 210 and 220 and the vertical connecting members 230, 240 and 250 are directly connected by screws 65 which are fastening members, the connection strength can be improved. For this reason, the outer sash 20A and inner sash 20B can be made larger, similar to when using aluminum frame material. Furthermore, since the lateral connecting member 210 can be manufactured by cutting a portion of the lateral connecting member 220, the lateral connecting members 210 and 220 can be manufactured from the same aluminum extruded profile. Also, the vertical connecting members 230 and 240 are made from the same aluminum extruded profile. Therefore, the lateral connecting members 210 and 220 and the vertical connecting members 230 and 240 can be modularized (made into common parts). Furthermore, by attaching functional components such as the door rollers 280, upper sliding pieces, and lower sliding pieces 290 to the horizontal connecting members 210, 220 and vertical connecting members 230, 240, and 250, the connecting function of the frame material and the support function of the functional components can be consolidated into the horizontal connecting members 210, 220 and vertical connecting members 230, 240, and 250. This improves the flexibility of the shape, material, and size of the exterior members 31, 32, 33, 34, and 35, and the interior members 41, 42, 43, 44, and 45. Even in joinery where the longitudinal dimensions or cross-sectional shape of the exterior and interior members are changed, the same horizontal and vertical connecting members can be used, thus standardizing the components.

[0039] Since the upper frame 21, lower frame 22, door edge frame 23, outer meeting frame 24, and inner meeting frame 25 are composed of aluminum exterior members 31, 32, 33, 34, and 35, and wooden interior members 41, 42, 43, 44, and 45, it is possible to construct outer sashes 20A and inner sashes 20B that have excellent weather resistance and excellent thermal insulation performance and interior design, similar to wooden windows. The horizontal connecting members 210, 220 and the vertical connecting members 230, 240, and 250 are not only fixed to the interior members 41, 42, 43, 44, and 45 with adhesive or double-sided tape, but are also fixed with screws 62 to the exterior members 31, 32, 33, 34, and 35 and the reinforcing members 51, 52, which are fixed to the interior members 41, 42, 43, 44, and 45 with screws 61. This allows the horizontal connecting members 210, 220 and the vertical connecting members 230, 240, and 250 to be firmly attached to the ends of each frame member. Furthermore, since the ends of the exterior members 31, 32, 33, 34, and 35 and the interior members 41, 42, 43, 44, and 45 are fixed to the horizontal connecting members 210, 220 and the vertical connecting members 230, 240, and 250 respectively, the rigidity of the ends of the frame members can also be improved.

[0040] [Second Embodiment] Next, the sliding window 1B of the second embodiment will be described with reference to Figures 9 to 13. The sliding window 1B of the second embodiment differs from the sliding window 1 of the first embodiment in that it uses synthetic resin interior members 71 to 75 instead of wooden interior members 41 to 45. For this reason, the same reference numerals are used for components identical to those in the first embodiment, and their descriptions are omitted or simplified.

[0041] The sliding window 1B comprises a window frame 10, an outer sash 20C, and an inner sash 20D. The window frame 10 has the same configuration as the sliding window 1 of the first embodiment, so its description is omitted.

The exterior members 31, 32, 33, 34, and 35 have the same configuration as in the first embodiment, so their description is omitted. The interior members 71, 72, 73, 74, and 75 correspond to the interior members 41 to 45 of the first embodiment and are extruded products made of synthetic resin. The interior members 71, 72, 73, 74, and 75 are equipped with multiple hollow sections and have main body sections 711, 721, 731, 741, and 751, guide piece sections 712, 722, and 732, and retaining piece sections 713, 723, 733, 743, and 753.

[0042] The main body portion 711 of the interior member 71 comprises an exterior surface portion 714 and interior surface portions 715, 716, and 717 extending from the exterior surface portion 714 toward the interior.

The interior surface portion 735 extends inward from the edge of the exterior surface portion 734 on the door-side, and the interior surface portion 726 extends inward from the inner circumference end of the exterior surface portion 734. The main body portion 741 of the interior member 74 comprises an exterior surface portion 744 and interior surface portions 745 and 746 extending from the exterior surface portion 744 toward the interior. The interior surface portion 745 extends toward the interior from the outer edge of the exterior surface portion 744, and the interior surface portion 746 extends toward the interior from the inner edge of the exterior surface portion 744. The main body 751 of the interior component 75 comprises an interior surface 752, an exterior surface 754, a visible surface 755, 756, 757, 758, and an intermediate visible surface 759. In the exterior surface 754, the portion connecting the visible surface 755, 756, and 757 is positioned further outward than the portion connecting the visible surface 757 and 758.

[0044] Reinforcement members 51B are fixed to the visible surfaces 717, 727, 736, and 746 with screws 61. Reinforcement member 51B is formed in an L-shape with a fixing surface portion 511 and a clamping piece portion 512. Like reinforcement members 51 and 52, reinforcement member 51B is made of aluminum, iron, stainless steel, or the like. As shown in Figure 9, the exterior member 31 and interior member 71 of the upper frame 21B are attached by the interior member 71 being locked to the second engaging piece 313 from the top, and the third engaging piece 313 from the top being clamped between the clamping piece 512 of the reinforcing member 51B and the interior member 71. Similarly, the exterior member 32 and interior member 72 of the lower frame 22B are attached by the fixing piece 324 being fixed to the bottom surface of the interior member 72 with a screw 61, and the first engaging piece 323 from the top being clamped between the clamping piece 512 of the reinforcing member 51B and the interior member 72. As shown in Figure 10, the exterior member 33 and interior member 73 of the door frame 23B are attached by fixing a fixing piece 334 to the visible surface 735 of the interior member 73 with a screw 61, and the first engaging piece 333 from the inner circumference is clamped between the clamping piece 512 of the reinforcing material 51B and the interior member 73. Similarly, the exterior member 34 and interior member 74 of the outer meeting stile 24B are attached by fixing a fixing piece 344 to the reinforcing material 36B located in the hollow part of the interior member 74 with a screw 61, and the first engaging piece 343 from the inner circumference is clamped between the clamping piece 512 of the reinforcing material 51B and the interior member 74. The exterior member 35 and interior member 75 of the interior meeting stile 25B are fixed to the exterior surface 754 and the interior surface 758 by screws 61, with the exterior surface 351 and the fixing piece 352 being fixed to the exterior surface 754 and the interior surface 758, respectively. In addition, the reinforcing member 52 has its fixing surface 521 fixed to the interior surface 758 by screws 61.

[0045] As shown in Figure 11, in the upper frame 21B, the left and right ends of the visible surface portion 715 and the upper part of the exterior surface portion 714 above the visible surface portion 716 are cut out, and the lateral connecting member 210 is attached to these cutouts with adhesive or double-sided tape. The lateral connecting member 210 has the same configuration as in the first embodiment, with the connecting reinforcing portion 211 placed on the upper surface of the visible surface portion 716, the engaging piece portion 212 and the fixing piece portion 213 engaging with the engaging piece portion 313 of the exterior member 31, and further, the fixing piece portion 213 is fixed to the exterior surface portion 311 of the exterior member 31 with screws 62. This lateral connecting member 210 reinforces the upper frame 21B and also has the upper sliding piece 990, which is a functional component, attached to it.

[0046] In the lower frame 22B, the left and right ends of the visible surface portion 725 and the lower part of the exterior surface portion 724 below the visible surface portion 726 are cut out, and the lateral connecting member 220 is attached to these cutouts with adhesive or double-sided tape. The lateral connecting member 220 has the same configuration as in the first embodiment, with the connecting reinforcing portion 221 abutting against the lower surface of the visible surface portion 726, the engaging piece portion 222 and the fixing piece portion 223 engaging with the engaging piece portion 323 of the exterior member 32, and further, the fixing piece portion 223 is fixed to the exterior surface portion 321 of the exterior member 32 with screws 62. This lateral connecting member 220 reinforces the lower frame 22B, and functional components such as the door roller 280 and the lower sliding piece 290 are attached to it.

[0047] As shown in Figure 12, in the door frame 23B, the upper and lower ends of the exterior surface 734 and the interior surface 735 and 736 are cut out, and the vertical connecting member 230 is attached to these cutouts with adhesive or double-sided tape. Similarly, in the exterior meeting stile 24B, the upper and lower ends of the exterior surface 744 and the interior surface 745 and 746 are cut out, and the vertical connecting member 240 is attached to these cutouts with adhesive or double-sided tape. The vertical connecting member 230 is fixed to the fixing piece 334 of the door frame 23B and the reinforcing member 51B with screws 62. The vertical connecting member 240 is fixed to the side covering portion 342 of the exterior meeting stile 24B and the reinforcing member 51B with screws 62. In the interior meeting stile 25B, the upper and lower ends of the facing surfaces 757 and 758 on the exterior side of the intermediate facing surface 759, and the upper and lower ends of the exterior surface 754 on the panel 26 side of the facing surface 756 are cut out, and the vertical connecting member 260 is attached to these cutouts with adhesive or double-sided tape. The vertical connecting member 260, like the vertical connecting member 250, comprises an exterior surface 261, a first facing surface 262, a second facing surface 263, an interior surface 264, and a connecting portion 265. This vertical connecting member 260 is fixed to the exterior member 35 and the reinforcing member 52 with screws 62. These vertical connecting members 230, 240, and 260 have one end face in the vertical direction that abuts against the horizontal connecting member 210 of the upper frame 21B and the horizontal connecting member 220 of the lower frame 22B, and are connected to the horizontal connecting members 210 and 220 by screws 65, which are fastening members that are screwed into the screw holes of the vertical connecting members 230, 240, and 260 via the horizontal connecting members 210 and 220.

[0048] As shown in Figure 10, the crescent receiver 37 is fixed to the interior member 74 by a screw 63 that is screwed into the reinforcing member 36B via the interior surface of the interior member 74. The crescent 38 is fixed to the reinforcing member 770 located in the hollow part of the interior member 75 by a screw 63. As shown in Figure 13, a notch similar to those at the upper and lower ends may be provided in the middle of the interior member 75 in the vertical direction, and a vertical connecting member 260, which serves as a metal intermediate member, may be attached to this notch. This allows the middle portion of the interior member 75, where the reinforcing member 770 to which the crescent 38 is fixed is provided, to be reinforced with the vertical connecting member 260.

[0049] [Effects of the second embodiment] In the sliding window 1B of the second embodiment, horizontal connecting members 210, 220 and vertical connecting members 230, 240, 260 are provided at the ends of the upper frame 21B, lower frame 22B, door edge frame 23B, outer meeting frame 24B, and inner meeting frame 25B. The horizontal connecting members 210, 220 and the vertical connecting members 230, 240, 260 are connected with screws 65, which are fastening members. As a result, the upper frame 21B, lower frame 22B, door edge frame 23B, outer meeting frame 24B, and inner meeting frame 25B are connected and assembled, thus achieving the same effect as the sliding window 1 of the first embodiment.

[0050] [Third Embodiment] Next, the sliding window 1C of the third embodiment will be described with reference to Figures 14 to 17. The sliding window 1C of the third embodiment is a sliding window similar to the sliding window 1 of the first embodiment, but differs in that instead of the upper frame 21, lower frame 22, door edge frame 23, outer meeting frame 24, and inner meeting frame 25, which are made of aluminum profiles for the exterior members 31, 32, 33, 34, 35 and wooden members 41, 42, 43, 44, 45, the upper frame 21C, lower frame 22C, door edge frame 23C, outer meeting frame 24C, and inner meeting frame 25C are made of synthetic resin. For this reason, the same reference numerals are used for components that are the same as in the first embodiment, and their descriptions are omitted or simplified.

[0051] The sliding window 1C comprises a window frame 10, an outer sash 20E, and an inner sash 20F. The window frame 10 has the same configuration as the sliding window 1 of the first embodiment, so its description is omitted. The outer sliding door 20E and the inner sliding door 20F are equipped with an upper frame 21C, a lower frame 22C, a door edge frame 23C, an outer meeting frame 24C, and an inner meeting frame 25C. As shown in Figure 14, the upper frame 21C is made of an extruded synthetic resin profile having a plurality of hollow sections. The upper frame 21C has an outdoor guide piece 811, an indoor guide piece 812, and a connecting piece 813 which constitute a guide groove in which the outer rail 115 and inner rail 116 are arranged, an outdoor retaining piece 814, an indoor retaining piece 815, and a connecting piece 816 which constitute a panel retaining groove that holds the panel 26 and gasket 27, and a connecting piece 817 provided between the connecting piece 813 and the connecting piece 816. The lower frame 22C is made of an extruded synthetic resin profile having multiple hollow sections.

[0058] [Differentiation] The present invention is not limited to the configurations described in the above embodiments, and any modifications that can achieve the objectives of the present invention are included in the present invention. The non-metallic materials used for the vertical and horizontal members may include wood, synthetic resins, resins containing wood powder, etc., and various materials with higher thermal insulation performance than metals can be used. Furthermore, the vertical and horizontal members may consist solely of non-metallic materials such as synthetic resins, as in the third embodiment, or they may consist of a metal exterior member and an interior member made of non-metallic materials such as wood or synthetic resin, as in the first and second embodiments, or they may consist of a synthetic resin exterior member and an interior member made of wood or synthetic resin. In addition, the interior member may consist of a main structure made of synthetic resin and a wooden decorative panel attached to the interior side of the main structure. In other words, vertical and horizontal members that are at least partially composed of non-metallic materials are those that use non-metallic materials such as wood or synthetic resins to enhance thermal insulation performance as main structural members that occupy a large area in the cross section perpendicular to the longitudinal direction. Therefore, vertical and horizontal members in which at least the main structural members are made of non-metallic materials are vertical and horizontal members that are at least partially composed of non-metallic materials. The fastening members connecting the horizontal connecting members 210, 220, and 910 with the vertical connecting members 230, 240, 250, and 260 are not limited to screws 65, but may also be rivets or other fastening members that can be assembled at the construction site. In the first and second embodiments described above, metal exterior members were used, but weather-resistant synthetic resin exterior members may also be used.

[0059] Functional components attached to horizontal and vertical connecting members are not limited to rollers or sliding pieces; they can also include auxiliary locks or any other component that enables various functions in the building fixture. Furthermore, the joinery is not limited to sliding window screens; it can also be a swing-type screen such as a casement window or a hinged window, or a sliding-type screen such as a single-hung window or a double-hung window, or even a fixed window. For example, a casement window can be constructed by attaching hinges, which are functional components, to horizontal and vertical connecting members. Furthermore, joinery equipped with horizontal and vertical connecting members is not limited to shoji screens; it may also be a window frame. That is, a frame material composed of an aluminum exterior member and an interior member made of synthetic resin or wood, or a synthetic resin frame material with horizontal and vertical connecting members provided at its longitudinal ends. In this case, vertical and horizontal frames, at least partially composed of non-metallic materials, can be easily assembled and attached to the building at the construction site. Furthermore, if the vertical and horizontal members connected by the horizontal and vertical connecting members include exterior and interior members, the exterior and interior members of the vertical and horizontal members may be attached to the horizontal and vertical connecting members, or only the exterior members of the vertical and horizontal members may be attached to the horizontal and vertical connecting members, or even only the interior members of the vertical and horizontal members may be attached to the horizontal and vertical connecting members. In other words, it is sufficient that at least one of the exterior and interior members of the vertical and horizontal members is attached to the horizontal and vertical connecting members.

[0060] [summary] The present invention relates to a joinery comprising vertical and horizontal members, at least in part, made of non-metallic material, wherein metal vertical connecting members are attached to both ends in the longitudinal direction of the vertical members, and metal horizontal connecting members are attached to both ends in the longitudinal direction of the horizontal members, and the vertical and horizontal members are connected by fastening members. According to the present invention, vertical and horizontal members are connected by attaching metal vertical and horizontal connecting members to the longitudinal ends of vertical and horizontal members, which are at least partially made of non-metallic material, and connecting these vertical and horizontal connecting members with fastening members. As a result, the joinery can be assembled using fastening members such as screws, improving assembly workability and enabling a knockdown system. Since the vertical and horizontal members are connected by fasteners such as screws, the connection strength can be improved compared to connecting non-metallic materials, and the strength of the joinery can also be increased. Furthermore, since at least a portion of the vertical and horizontal members are made of non-metallic materials such as wood or synthetic resin, the thermal insulation performance of the vertical and horizontal members can be improved.

[0061] In the building fittings of the present invention, it is preferable that a functional component is attached to at least one of the vertical connecting member and the horizontal connecting member. According to the present invention, functional components such as rollers and sliding pieces are attached to the vertical and horizontal connecting members, eliminating the need to attach functional components to non-metallic materials. Therefore, there is no need to perform special processing to attach rollers and the like to non-metallic materials, making the processing of non-metallic materials easier and reducing costs.

[0062] In the building fittings of the present invention, the vertical member and the horizontal member preferably comprise an exterior member and an interior member, and at least one of the exterior member and the interior member is preferably attached to the vertical connecting member and the horizontal connecting member, respectively. According to the present invention, since the vertical and horizontal members are composed of exterior and interior members, the exterior members, which are exposed to wind, rain, and direct sunlight, can be made of weather-resistant metal or synthetic resin materials, while the interior members, which are exposed to the interior side, can be made of wood or synthetic resin materials with excellent heat insulation and design properties. Furthermore, since at least one of the longitudinal ends of the exterior and interior members is attached to the vertical and horizontal connecting members, the strength of the ends of the vertical and horizontal members can be improved, and the connection strength of the vertical and horizontal members can also be further improved. As a result, it is possible to make the joinery larger.

[0063] In the joinery of the present invention, the vertical members and horizontal members are frame members that are framed and hold a panel inside, the interior member is made of a material with higher thermal insulation properties than the exterior member, and in the intermediate portions of the vertical members and horizontal members where the vertical connecting members and horizontal connecting members are not provided, it is preferable that the exterior surface of the interior member is positioned on the exterior side of the center position in the depth direction of the panel. According to the present invention, the depth dimension of the non-metallic interior members is increased in most of the longitudinal direction, except for the ends of the vertical and horizontal members, and the area occupied by the interior members is larger than that of the exterior members in the cross-section of the vertical and horizontal members, thus providing a building component with excellent thermal insulation properties.

[0064] In the building fittings of the present invention, it is preferable that the vertical connecting member and the horizontal connecting member are in contact with each other and directly connected by the fastening member. According to the present invention, since the vertical connecting members and horizontal connecting members are in contact with each other and directly connected by the connecting members, the fastening force of fastening members such as screws can be increased compared to cases where non-metallic materials are interposed between them, thereby improving the connection strength between the vertical and horizontal members.

[0065] In the building fittings of the present invention, it is preferable that a metal intermediate member is placed at an intermediate position in the longitudinal direction of the vertical member or at an intermediate position in the longitudinal direction of the horizontal member, and that a functional component is attached to the intermediate member. According to the present invention, since a metal intermediate member is positioned at an intermediate position in the longitudinal direction of the vertical and horizontal members, functional components such as handles and lock parts can be attached to the intermediate member, and the mounting strength of these functional components can be improved.

[0066] In the building fittings of the present invention, the vertical member and the horizontal member each comprise an exterior member and an interior member, the horizontal connecting member and the exterior member of the horizontal member are fastened together by a second fastening member, and it is preferable that the exterior member of the vertical member is positioned on the exterior side of the exterior member of the horizontal member and covers the second fastening member. According to the present invention, the second fastening member that fastens the horizontal connecting member and the outdoor member of the horizontal member can be covered by the outdoor member of the vertical member, and since the second fastening member is not exposed to the outside, the aesthetic appearance and watertightness can be improved.
