Summary of the Invention

Problems to be Solved by the Invention

[0004] For example, in the case of a picture frame with a relatively large opening, there may be variations in the dimensions of the left, right, top, and bottom of the picture frame. For such a picture frame, it becomes difficult to accurately incorporate the picture frame extension member assembled as designed. In that case, the dimensions were adjusted by sandwiching a spacer between the horizontal frame member and the vertical frame member and fixing them, but this was time-consuming and led to a deterioration in workability. Therefore, an object of the present disclosure is to provide a fitting and a construction method thereof that can accurately incorporate a picture frame extension member corresponding to the picture frame and improve workability.

[0014] As shown in Figures 2 and 3, the frame extension member 4 is provided on the interior side of the frame 3 and is positioned along the outer edge on the interior side of the interior window 6. The frame extension member 4 is fixed to the frame 3 by screws. The frame extension member 4 is a member that is attached to the frame 3 to support the interior window 6 when the depth dimension of the existing frame 3 is small and the frame 3 cannot sufficiently surround and support the interior window 6. The frame extension member 4 has an upper horizontal frame member 41, a lower horizontal frame member 42, and a pair of left and right vertical frame members 43. The upper horizontal frame member 41, the lower horizontal frame member 42, and each of the vertical frame members 43 are framed around all four sides. The upper horizontal frame member 41 and the lower horizontal frame member 42 are examples of horizontal frame members of this disclosure. The interior side surface of the frame extension member 4 is positioned so as to generally align with the interior side surface of the interior window 6 in the depth direction.

[0015] The upper horizontal frame member 41 is a long-shaped profile with a square tubular hollow structure, and is arranged to extend in the left-right direction above the inner window 6. As shown in FIG. 2, the upper horizontal frame member 41 has an upper top surface member portion 41a, a lower bottom surface member portion 41b, an inner surface member portion 41c on the indoor side, and an outer surface member portion 41d on the outdoor side, and these surface member portions are integrally formed in a square tubular shape. The outer surface member portion 41d of the upper horizontal frame member 41 is fixed to the indoor side surface of the upper lintel 31 by screws. An opening is formed in the inner surface member portion 41c for screwing the screws passed through the outer surface member portion 41d into the upper lintel 31. The upper surface of the upper frame 61 of the inner window 6 is fixed to the lower bottom surface member portion 41b by screws 41g.

[0016] The lower horizontal frame member 也可翻译为:The lower cross-frame member) 42 is a long-shaped profile with a square tubular hollow structure, and is arranged to extend in the left-right direction below the inner window 6. As shown in FIG. 2, the lower horizontal frame member 42 has an upper top surface member portion 42a, a lower bottom surface member portion 42b, an inner surface member portion 42c on the indoor side, and an outer surface member portion 42d on the outdoor side, and these surface member portions are integrally formed in a square tubular shape. The outer surface member portion 42d of the lower horizontal frame member 42 is fixed to the indoor side surface of the lower lintel 32 by screws. An opening is formed in the inner surface member portion 42c for screwing the screws into the lower lintel 32. The lower surface of the lower frame 62 of the inner window 6 is fixed to the upper top surface member portion 42a by screws 42g.

The vertical frame member 43 is a long-shaped profile with a square tubular hollow structure, and is arranged to extend in the vertical direction between the left and right ends of the upper horizontal frame member 41 and the lower horizontal frame member 42. As shown in FIG. 3, the vertical frame member 43 has an inner peripheral surface member portion 43a on the inner peripheral side, an outer peripheral surface member portion 43b on the outer peripheral side, an inner surface member portion 43c on the indoor side, and an outer surface member portion also可翻译为:an outer surface member part) 43d on the outdoor side, and these surface member portions are integrally formed in a square tubular shape. The outer surface member portion 43d of the vertical frame member 43 is fixed to the indoor side surface of the vertical lintel 33 by screws. An opening is formed in the inner surface member portion 43c for screwing the screws into the vertical lintel 33. The outer peripheral side surface of the vertical frame 63 of the inner window 6 is fixed to the inner peripheral surface member portion 43a by screws 43g.

[0018] The cover member 5 is a resin molded member that covers the indoor side surface and the outer peripheral side surface of the frame extension member 4. As shown in FIG. 1, the cover member 5 includes an upper horizontal frame cover 51 disposed on the upper horizontal frame member 41, a lower horizontal frame cover 52 disposed on the lower horizontal frame member 42, vertical frame covers 53 disposed on the left and right vertical frame members 43, upper corner covers 54 on the left and right, and lower corner covers 55 on the left and right.

[0019] As shown in FIGS. 2 and 3, each of the upper horizontal frame cover 51, the lower horizontal frame cover 52, and the vertical frame cover 53 has a substantially L-shaped cross-section that covers the indoor side surface and the outer peripheral side surface of each member 41, 42, 43 of the frame extension member 4. Small protrusions 41e, 42e, and 43e for engaging with the cover member 5 are provided on the upper horizontal frame member 41, the lower horizontal frame member 4, and the vertical frame member 43, respectively. On the other hand, an engaging portion 51e for elastically engaging with the protrusion 41e is provided on the upper horizontal frame cover 51. Also, an engaging portion 52e for elastically engaging with the protrusion 42e is provided on the lower horizontal frame cover 52. Further, an engaging portion 53e for elastically engaging with the protrusion 4 is provided on the vertical frame cover 53.

[0020] The upper horizontal frame cover 51 is incorporated so as to cover the indoor side surface and the outer peripheral side surface of the upper horizontal frame member 41, and the protrusion 41e elastically engages with the engaging portion 51e. In this state, the indoor side surface of the upper horizontal frame cover 51 abuts against the inner surface member portion 41c of the upper horizontal frame member 41 and covers the indoor side surface of the inner surface member portion 41c, and the outer peripheral side surface of the upper horizontal frame cover 51 abuts against the upper surface member portion 41a of the upper horizontal frame member 41 and covers the outer peripheral side surface of the upper surface member portion 41a.

[0021] The lower horizontal frame cover 52 is incorporated so as to cover the indoor side surface and the outer peripheral side surface of the lower horizontal frame member 42, and the protrusion 42e elastically engages with the engaging portion 52e. In this state, the indoor side surface of the lower horizontal frame cover 52 abuts against the inner surface member portion 42c of the lower horizontal frame member 42 and covers the indoor side surface of the inner surface member portion 42c, and the outer peripheral side surface of the lower horizontal frame cover 52 abuts against the lower surface member portion 42b of the lower horizontal frame member 42 and covers the outer peripheral side surface of the lower surface member portion 42b.

[0022] [[ID=】] The vertical frame cover 53 is assembled to cover the indoor and outer surfaces of the vertical frame member 43, and the projection 43e elastically engages with the engaging portion 53e. In this state, the indoor surface of the vertical frame cover 53 abuts against the indoor surface of the inner material portion 43c of the vertical frame member 43 and covers the indoor surface of the inner material portion 43c, and the outer surface of the vertical frame cover 53 abuts against the outer surface of the outer surface material portion 43b of the vertical frame member 43 and covers the outer surface of the outer surface material portion 43b.

[0023] As shown in Figure 1, the frame extension member 4 according to this embodiment has a pair of left and right upper corner portions 4A which are connecting portions between the left and right ends of the upper horizontal frame member 41 and the upper end of the vertical frame member 43, and a pair of left and right lower corner portions 4B which are connecting portions between the left and right ends of the lower horizontal frame member 42 and the lower end of the vertical frame member 43.

[0024] The upper corner covers 54 are positioned on each upper corner portion 4A of the frame extension member 4 and cover the interior-facing and exterior-facing surfaces of these upper corner portions 4A. The lower corner covers 55 are positioned on each lower corner portion 4B of the frame extension member 4 and cover the interior-facing and exterior-facing surfaces of these lower corner portions 4B. Each of the upper corner covers 54 and lower corner covers 55 is engaged with the upper corner portion 4A and lower corner portion 4B by engaging means (not shown).

[0025] In the picture frame extension member 4 according to this embodiment, the connection portion between the left and right ends of the upper horizontal frame member 41 and the upper end of the vertical frame member 43 is the upper corner portion 4A, and the connection portion between the left and right ends of the lower horizontal frame member 42 and the lower end of the vertical frame member 43 is the lower corner portion 4B.

[0026] The connection between the left and right ends of the upper horizontal frame member 41 and the upper end of the vertical frame member 43 in the upper corner section 4A, and the connection between the left and right ends of the lower horizontal frame member 42 and the lower end of the vertical frame member 43 in the lower corner section 4B, are not made by directly fixing the members together with screws, but rather by fastening them with screws via connecting fittings 70, which are connecting members, as shown below.

[0027] Figure 4 shows the left side of the door 1 as seen from the interior, and Figure 5 shows the same part as shown in Figure 4 as seen from the exterior. Note that the frame 3 and cover member 5 are not shown in Figures 4 and 5. As shown in Figures 4 and 5, the left end of the upper horizontal frame member 41 and the upper end of the vertical frame member 43 are connected via a connecting fitting 70.

[0028] Figure 6 shows the state in which the left end of the upper horizontal frame member 41 and the upper end of the vertical frame member 43 are connected via the connecting fitting 70, and Figure 7 shows the connecting fitting 70 in that state.

[0029] As shown in Figure 6, multiple elongated holes 41f are provided near the left end of the inner material portion 41c that constitutes the indoor-facing surface 41m of the upper horizontal frame member 41. In this embodiment, two elongated holes 41f are provided side by side, spaced apart in the left-right direction. The elongated holes 41f are elongated holes that extend in the left-right direction of the upper horizontal frame member 41 and penetrate through in the depth direction. Each of these elongated holes 41f is a screw insertion hole through which a screw 80, described later, is inserted from the indoor side.

[0030] As shown in Figure 6, multiple elongated holes 43f are provided near the upper end of the inner material portion 43c that constitutes the interior surface 43m of the vertical frame member 43. In this embodiment, two elongated holes 43f are provided side by side, spaced apart in the vertical direction. The elongated holes 43f are elongated holes that extend in the vertical direction of the vertical frame member 43 and penetrate in the depth direction. Each of these elongated holes 43f is a screw insertion hole through which a screw 80, described later, is inserted from the interior side.

[0031] As shown in Figure 7, the connecting fitting 70 has an L-shaped plate portion 71 in which a plate material is bent into an L shape, and rectangular fixing plate portions 72 integrally provided at both ends of the L-shaped plate portion 71.

[0032] The L-shaped plate section 71 has a pair of plate sections 71a that are arranged to face parallel to the depth surface of the joinery 1. One plate section 71a of the L-shaped plate section 71 is arranged to extend in the left-right direction, and the other plate section 71a is arranged to extend in the up-down direction. The pair of plate sections 71a are connected via a bent section 71k that bends at a right angle.

[0033] Each of the fixing plate portions 72 is positioned on the leading edge side of each plate portion 71a. The fixing plate portions 72 are positioned parallel to the visible surface of the joinery 1. The fixing plate portions 72 are formed in such a manner that they bend outward at a right angle from one end of each plate portion 71a on the interior side in the width direction (corresponding to the depth direction). The length direction of the fixing plate portion 72 is aligned with the direction in which the plate portion 71a extends. Multiple screw holes 73 are provided on each fixing plate portion 72 near the plate portion 71a. In this embodiment, two screw holes 73 are provided side by side with a gap between them in the length direction of the fixing plate portion 72.

[0034] The connecting fitting 70 is constructed such that one plate portion 71a of the L-shaped plate portion 71 is inserted into the left end of the upper horizontal frame member 41, and the inner material portion 41c is fixed to the inserted fixing plate portion 72. The other plate portion 71a of the L-shaped plate portion 71 is inserted into the upper end of the vertical frame member 43, and the inner material portion 43c is fixed to the inserted fixing plate portion 72. In this way, the left end of the upper horizontal frame member 41 and the upper end of the vertical frame member 43 are connected via the connecting fitting 70. When the connecting fitting 70 is viewed from the indoor side, the bent portion 71k is located to the upper left of the left upper corner portion 4A.

[0035] The two elongated holes 41f in the inner surface material portion 41c of the upper horizontal frame member 41 are located in areas that coincide with the two screw holes 73 of the fixing plate portion 72 inserted into the upper horizontal frame member 41, allowing screws 80 passed through from the indoor side to be screwed into the screw holes 73. With the screws 80 screwed into the screw holes 73 but not yet fixed, the upper horizontal frame member 41 can move in the left-right direction, which is its own longitudinal direction, by a distance corresponding to the length of the elongated holes 41f. Therefore, the upper horizontal frame member 41 can be relatively adjusted in the left-right fixing position relative to the vertical frame member 43. The adjustment distance will correspond to the length of the elongated holes 41f. The elongated holes 41f and the screws 80 are covered by the upper horizontal frame cover 51 and are not visible from the indoor side.

[0036] The two elongated holes 43f in the inner material portion 43c of the vertical frame member 43 are located in areas that coincide with the two screw holes 73 of the fixing plate portion 72 inserted into the vertical frame member 43, allowing screws 80 to be threaded through these two elongated holes 43f from the indoor side into the screw holes 73. With the screws 80 threaded into the screw holes 73 but not yet fixed, the vertical frame member 43 can move vertically in its longitudinal direction by a distance corresponding to the length of the elongated holes 43f. Therefore, the vertical fixing position of the vertical frame member 43 relative to the upper horizontal frame member 41 can be adjusted. The adjustment distance corresponds to the length of the elongated holes 43f. The elongated holes 43f and screws 80 are covered by the vertical frame cover 53 and are not visible from the indoor side.

[0037] Figures 6 and 7 show a structure in which the left end of the upper horizontal frame member 41 and the upper end of the vertical frame member 43 are fastened together with screws via a connecting fitting 70. Similarly, the right end of the upper horizontal frame member 41 and the upper end of the vertical frame member 43 are also connected via a connecting fitting 70. Although the illustration of this connection structure is omitted, the arrangement of the connecting fitting 70 is such that, when viewed from the interior side, the bent portion 71k is located to the upper right of the right upper corner portion 4A.

[0038] Figure 8 shows the state in which the left end of the lower horizontal frame member 42 and the lower end of the vertical frame member 43 are connected via the connecting fitting 70, and Figure 9 shows the connecting fitting 70 in that state.

[0039] As shown in Figure 8, multiple elongated holes 42f are provided near the left end of the inner material portion 42c that constitutes the visible surface 42m of the indoor side of the lower horizontal frame member 42. In this embodiment, two elongated holes 42f are provided side by side, spaced apart in the left-right direction. The elongated holes 42f are elongated holes that extend in the left-right direction of the lower horizontal frame member 42 and penetrate in the depth direction. Each of these elongated holes 42f is a screw insertion hole through which a screw 80, described later, is inserted from the indoor side.

[0040] As shown in Figure 8, multiple elongated holes 43f are provided near the lower end of the inner material portion 43c that constitutes the visible surface 43m on the indoor side of the vertical frame member 43. In this embodiment, two elongated holes 43f are provided side by side, spaced apart in the vertical direction. The elongated holes 43f are elongated holes that extend in the vertical direction of the vertical frame member 43 and penetrate in the depth direction. Each of these elongated holes 43f is a screw insertion hole through which a screw 80, described later, is inserted from the indoor side.

[0041] The connecting fitting 70 shown in Figure 9 is the same as the connecting fitting 70 shown in Figure 7. Therefore, in Figure 9, the same reference numerals are used for components that are the same as those in Figure 7.

[0042] The connecting fitting 70 is constructed such that one plate portion 71a of the L-shaped plate portion 71 is inserted into the left end of the lower horizontal frame member 42, and the inner material portion 42c is fixed to the inserted fixing plate portion 72. The other plate portion 71a of the L-shaped plate portion 71 is inserted into the lower end of the vertical frame member 43, and the inner material portion 43c is fixed to the inserted fixing plate portion 72. In this way, the left end of the lower horizontal frame member 42 and the lower end of the vertical frame member 43 are connected via the connecting fitting 70. When the connecting fitting 70 is viewed from the interior side, the bent portion 71k is located to the lower left of the left lower corner portion 4B.

[0043] The two elongated holes 42f in the inner surface material portion 42c of the lower horizontal frame member 42 are located in areas that coincide with the two screw holes 73 of the fixing plate portion 72 inserted into the lower horizontal frame member 42, allowing screws 80 passed through from the indoor side to be screwed into the screw holes 73. With the screws 80 screwed into the screw holes 73 but not yet fixed, the lower horizontal frame member 42 can move in the left-right direction, which is its own longitudinal direction, by a distance corresponding to the length of the elongated holes 42f. Therefore, the lower horizontal frame member 42 can be relatively adjusted in the left-right fixing position relative to the vertical frame member 43. The adjustment distance will correspond to the length of the elongated holes 42f. The elongated holes 42f and the screws 80 are covered by the lower horizontal frame cover 52 and are not visible from the indoor side.

[0044] The two elongated holes 43f in the inner surface portion 43c of the vertical frame member 43 are located in areas that coincide with the two screw holes 73 of the fixing plate portion 72 inserted into the vertical frame member 43, allowing screws 80 to be threaded through these two elongated holes 43f from the indoor side into the screw holes 73. With the screws 80 threaded into the screw holes 73 but not yet fixed, the vertical frame member 43 can move vertically in its longitudinal direction by a distance corresponding to the length of the elongated holes 43f. Therefore, the vertical fixing position of the vertical frame member 43 relative to the lower horizontal frame member 42 can be adjusted. The adjustment distance corresponds to the length of the elongated holes 43f. The elongated holes 43f and screws 80 are covered by the vertical frame cover 53 and are not visible from the indoor side.

[0045] Figures 8 and 9 show a structure in which the left end of the lower horizontal frame member 42 and the lower end of the vertical frame member 43 are fastened together with screws via a connecting fitting 70. Similarly, the right end of the lower horizontal frame member 42 and the lower end of the vertical frame member 43 are also connected via a connecting fitting 70. Although the illustration of this connection structure is omitted, the arrangement of the connecting fitting 70 is such that, when viewed from the interior side, the bent portion 71k is located to the lower right of the right-side lower corner portion 4B.

[0046] Figure 10 is a perspective view of the vertical frame member 43 when viewed diagonally from the indoor side. Figure 11 is a perspective view of the vertical frame member 43 when viewed diagonally from the outdoor side. As shown in Figures 10 and 11, notches 43k are formed at the upper and lower ends of the outer surface material portion 43d that constitutes the outdoor side surface of the vertical frame member 43. The notches 43k have a rectangular shape that extends in the vertical direction and opens to the outdoor side. The notch 43k on the upper end side opens upward, and the notch 43k on the lower end side opens downward. These notches 43k are formed in the parts corresponding to the connecting fitting 70, and the plate portion 71a of the connecting fitting 70 and the fixing plate portion 72 continuous with this plate portion 71a are provided to pass through in the depth direction.

[0047] The above describes the configuration of the joinery 1 according to the embodiment. Next, an example of an installation method for arranging the frame extension member 4 described above in the frame 3 will be explained below.

[0048] First, the upper horizontal frame member 41 and the lower horizontal frame member 42, each with connecting fittings 70 temporarily attached to both ends, are placed on the interior-facing surfaces of the upper frame 31 and lower frame 32 of the picture frame 3. At this stage, they may be simply supported without being screwed in, or they may be fixed to the picture frame 3 with screws. If fixed with screws, the upper horizontal frame member 41 and the lower horizontal frame member 42 are positioned appropriately relative to the picture frame 3 and then fixed. In this case, the upper horizontal frame member 41 and the lower horizontal frame member 42 become pre-attached members according to this disclosure, and the vertical frame member 43 becomes a post-attached member according to this disclosure.

[0049] Next, the left and right vertical frame members 43 are placed on the interior side of the vertical frame 33 of the picture frame 3. This arrangement involves moving the vertical frame members 43 from the interior side to the exterior side, passing the connecting fitting 70 through the notch 43k, and inserting the connecting fitting 70 into the interior of the vertical frame member 43.

[0050] Next, the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43 are fixed to the connecting fitting 70, and the frame extension member 4 is assembled. In this step, screws 80 are screwed into the respective screw holes 73 of the connecting fitting 70 from the inside through the elongated holes 41f, 42f, and 43f. However, the screws 80 are left loose without being fully tightened, and the positions of the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43 are positioned to the correct positions relative to the frame 3 using the elongated holes 41f and 42f that extend in the left-right direction. By moving any of the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43 in the left-right direction using the elongated holes 41f and 42f that extend in the left-right direction, the left-right positioning can be achieved. Furthermore, by using the elongated holes 43f that extend in the vertical direction, the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43 can be moved vertically to position them. The connecting fitting 70 may also move during positioning. If the upper horizontal frame member 41 and the lower horizontal frame member 42 are initially fixed to the picture frame 3, the vertical frame member 43 can be moved up, down, left, or right to position it. This positioning allows the entire picture frame extension member 4 to be positioned correctly relative to the picture frame 3. After this, the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43 are fixed to the picture frame 3 with screws.

[0051] Next, the upper horizontal frame cover 51 is placed on the upper horizontal frame member 41, the lower horizontal frame cover 52 is placed on the lower horizontal frame member 42, and the vertical frame covers 53 are placed on the left and right vertical frame members 43. Furthermore, the left and right upper corner covers 54 are placed on the left and right upper corner sections 4A respectively, and the left and right lower corner covers 55 are placed on the left and right lower corner sections 4B respectively, and the cover member 5 is assembled.

[0052] After the installation of the frame extension member 4 and the cover member 5 is completed as described above, the inner window 6 is incorporated into the inner circumference of the frame extension member 4.

[0053] The above-described method of installing the frame extension member 4 is just one example; for example, the lower horizontal frame member 42 may be placed in the frame 3 first, and then the left and right vertical frame members 43 and the upper horizontal frame member 41 may be placed afterward.

[0054] The joinery 1 according to the embodiment described above provides the following effects.

[0055] The joinery 1 according to this embodiment comprises a frame 3 placed in an opening 2 of a building, and a frame extension member 4 provided on the interior side of the frame 3. The frame extension member 4 is a joinery having an upper horizontal frame member 41 and a lower horizontal frame member 42 that extend in the left-right direction, and a vertical frame member 43 that extends in the up-down direction. The upper horizontal frame member 41 and the lower horizontal frame member 42 and the vertical frame member 43 are connected by screw fastening via a connecting fitting 70, which is a connecting member. At least one of the horizontal frame members 41, 42 and the vertical frame member 43 has an elongated hole extending in the direction of extension of the member as a screw insertion hole on its interior-side facing surface. The connecting fitting 70 has screw holes 73 corresponding to the elongated hole when the horizontal frame members 41, 42 and the vertical frame member 43 are assembled. The member having the elongated hole is fixed to the connecting fitting 70 by screwing a screw 80 inserted through the elongated hole into the screw hole 73. The visible surfaces according to this embodiment are the visible surface 41m of the upper horizontal frame member 41, the visible surface 42m of the lower horizontal frame member 42, and the visible surface 43m of the vertical frame member 43. The elongated holes according to this embodiment are the elongated hole 41f of the upper horizontal frame member 41, the elongated hole 42f of the lower horizontal frame member 42, and the elongated hole 43f of the vertical frame member 43.

[0056] In this embodiment, the frame extension member 4 allows the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43 to be moved vertically and horizontally using the elongated holes 41f, 42f, and 43f to adjust their positions. This allows the entire frame extension member 4 to be accurately assembled to the correct position corresponding to the frame 3 from the interior side by adjusting the position of at least one of the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43, for example, if the opening 2 of the frame 3 is relatively large and there are variations in the left, right, top, and bottom dimensions of the frame 3. Therefore, the entire frame extension member 4 can be accurately assembled to the correct position corresponding to the frame 3 from the interior side. Consequently, there is no need to take the trouble to adjust dimensions by inserting spacers between the horizontal frame members and vertical frame members as in the conventional method, improving ease of installation.

[0057] In the joinery 1 according to this embodiment, the upper horizontal frame member 41 and the lower horizontal frame member 42 and the vertical frame member 43 are pre-installed members, one of which is placed first on the interior side of the frame 3, and the other is a post-installed member, which is placed on the interior side of the frame 3 after the pre-installed members. In the above-described embodiment, the upper horizontal frame member 41 and the lower horizontal frame member 42 are pre-installed members, and the vertical frame member 43 is a post-installed member. The post-installed vertical frame member 43 has a notch 43k on its exterior surface corresponding to the connecting fitting 70, which opens to the exterior and allows the connecting fitting 70 to pass through.

[0058] This allows the vertical frame member 43, which is an add-on component, to be moved from the indoor side to the outdoor side without interfering with the connecting fitting 70, and to be smoothly positioned in the picture frame 3.

[0059] In the joinery 1 according to this embodiment, covers are provided on the interior-facing surfaces of the upper horizontal frame member 41, the lower horizontal frame member 42, and the vertical frame member 43, each having elongated holes 41f, 42f, and 43f, respectively, to cover at least the elongated holes 41f, 42f, 43f and the screws 80. The covers according to the above embodiment are an upper horizontal frame cover 51 provided on the interior-facing surface of the upper horizontal frame member 41, a lower horizontal frame cover 52 provided on the interior-facing surface of the lower horizontal frame member 42, and a vertical frame cover 53 provided on the interior-facing surface of the vertical frame member 43.

[0060] As a result, the elongated holes 41f, 42f, 43f and the screws 80 are not visible from the interior side, improving the appearance from the interior.

[0061] The method for installing the joinery 1 according to this embodiment involves placing the pre-installed member with the connecting fitting 70 attached on the interior side of the frame 3, and then moving the post-installed member from the interior side to the exterior side, passing the notch 43k through the connecting fitting 70, and placing it on the interior side of the frame 3. In the above-described embodiment, the upper horizontal frame member 41 and the lower horizontal frame member 42 are pre-installed members, and the vertical frame member 43 is a post-installed member.

[0062] This allows the vertical frame member 43, which is an add-on component, to be moved from the indoor side to the outdoor side without interfering with the connecting fitting 70, and to be smoothly positioned in the picture frame 3.

[0063] The building components described herein are not limited to the embodiments described above, and any modifications, improvements, etc., to the extent that they can achieve the purpose of this disclosure are included herein.

[0064] For example, the elongated holes provided on the interior-facing surface as screw insertion holes may be provided on both the horizontal frame member and the vertical frame member as in the above embodiment, or on only one of them. Also, the number of elongated holes provided on a single member is arbitrary and may be one or three or more. The number of screw holes 73 on the connecting fitting 70 side will correspond to the number of elongated holes. Furthermore, the elongated hole may be a single elongated hole having a length that spans multiple screw holes 73. As for the pre-attached member and the post-attached member, contrary to the above embodiment, the pre-attached member may be a vertical frame member and the post-attached member may be a horizontal frame member. The form of the connecting fitting 70 is not limited to the form of the above embodiment, and any form is acceptable as long as it has screw holes corresponding to the elongated holes formed on the interior-facing surface of the horizontal frame member and the vertical frame member, and can connect these horizontal frame member and vertical frame member. The frame extension member 4 may be a so-called four-sided configuration that surrounds all four sides as in the above embodiment, or it may be a three-sided configuration in which, for example, the upper horizontal frame member 41 is omitted.

[0065] In the above embodiment, the inner window 6 is a sliding window, but the type of inner window 6 is not limited and may be, for example, an opening window or a fixed window, and even in the case of an opening window, the number of sashes may be two or more. [Explanation of Symbols]
