Description

[[Technical Field]]

[0001] The present invention relates to a fitting including a panel fixed to a frame body. [[Background Art]]

[0002] A frame body of a fitting forms an opening with an upper frame, a lower frame, and left and right vertical stiles. A panel is disposed in the opening of the frame body and fixed to the frame body. The frame body has a vertical molding attached to the vertical stile, and holds the panel with the vertical molding. Further, as a fitting provided with such a vertical molding, there has been conventionally known a fitting in which a glass plate serving as a panel is fixed by a molding provided with a main body portion and a cover portion (see Patent Document 1).

[0003] In the conventional fitting described in Patent Document 1, the molding forms a groove portion for accommodating the glass plate by the main body portion and the cover portion. The glass plate is sandwiched between the arm of the main body portion and the arm of the cover portion in the groove portion of the molding, and is fixed to the molding. However, when fixing the glass plate, after fixing the main body portion of the molding to the vertical stile with screws, it is necessary to fit the cover portion of the molding onto the main body portion. Therefore, in the conventional fitting, attaching the molding to the vertical stile sometimes takes time and labor, and there is room for improvement from the viewpoint of improving workability of the glass plate fixing work using the molding.

[0009] One embodiment of the building component of the present invention will be described with reference to the drawings. The joinery of this embodiment is a window body comprising a panel fixed to a frame, and is installed on the exterior wall of a building or inside a building. The joinery is installed in an opening in a building to close the opening. Two embodiments of the joinery will be described in order below.

[0010] (First Embodiment) Figure 1 is a front view of the joinery 1 of the first embodiment, showing the joinery 1 installed in a building as viewed from the front. Figure 2 is a longitudinal section view of the joinery 1 of the first embodiment, showing the joinery 1 cut by a plane that includes the vertical direction R and the thickness direction T of the joinery 1. Figure 3 is a transverse section view of the joinery 1 of the first embodiment, showing the joinery 1 cut by a plane that includes the horizontal direction S and the thickness direction T of the joinery 1.

[0011] When the joinery 1 installed in the building is viewed from the front, the up-and-down direction is R, and the left-and-right direction is S. In Figure 1, the up-and-down direction R is the vertical direction, and the left-and-right direction S is the horizontal direction. The thickness direction T of the joinery 1 is the thickness direction of the joinery 1 installed in the building. Also, the thickness direction T of the joinery 1 is the front-to-back direction (depth direction) when the joinery 1 installed in the building is viewed from the front, and in Figure 3, it is the horizontal direction perpendicular to the left-and-right direction S. Thus, the direction related to the joinery 1 is specified by the direction in which the joinery 1 is installed in the building.

[0012] As shown in the figure, the fitting 1 includes a panel 2 and a frame body 3 surrounding the panel 2. The panel 2 is a rectangular glass panel (for example, flat glass, double glazing, or laminated glass), and is arranged inside the frame body 3. The frame body 3 is a rectangular opening frame that forms an opening 3A, and is attached to the building frame (not shown in the figure). The opening 3A of the frame body 3 is formed in a rectangular shape on the inner side of the frame body 3. The fitting 1 is a fixed window, and the panel 2 is a fixed panel. The panel 2 is arranged in the rectangular opening 3A of the frame body 3 and fixed to the frame body 3.

[0013] The frame body 3 has four frames 4 to 6 (an upper frame 4, a lower frame 5, and a pair of vertical frames 6) assembled with each other and a mullion 7, and the opening 3A is formed by the frames 4 to 6 and the mullion 7. The frames 4 to 6 and the mullion 7 of the frame body 3 are frame members (frame constituent members) that constitute the frame body 3, each of which is made of a metal (for example, aluminum alloy) profile formed by extrusion molding. The longitudinal direction of the frames 4 to 6 and the mullion 7 is the direction in which the frames 4 to 6 and the mullion 7 extend (extending direction). The longitudinal direction of the upper frame 4 and the lower frame 5 is the left-right direction S, and the longitudinal direction of the vertical frames 6 and the mullion 7 is the up-down direction R.

[0014] The upper frame 4 and the lower frame 5 are upper and lower horizontal frames (upper horizontal frame and lower horizontal frame) located at the upper portion and the lower portion of the frame body 3, respectively, and extend in the horizontal direction (the left-right direction S). The pair of vertical frames 6 are side frames located on the left and right sides of the frame body 3, and extend in the vertical direction (the up-down direction R). The mullion 7 is a vertical member extending in the vertical direction, is spaced apart from each of the left and right vertical frames 6, and is located between the left and right vertical frames 6. The ends of the upper frame 4, the lower frame 5, the left and right vertical frames 6, and the mullion 7 are connected to each other, so that the frames 4 to 6 and the mullion 7 are framed.

[0015] The upper frame 4 and the lower frame 5 have the same shape as each other in a cross section orthogonal to the respective longitudinal directions (cross-sectional shape), and are arranged plane-symmetrically to each other. Further, the upper frame 4 and the lower frame 5 are made of profiles (extruded profiles) having the same cross-sectional shape, and are formed to have the same length as each other. The upper frame 4 and the lower frame 5 are arranged plane-symmetrically with respect to a symmetry plane therebetween. The symmetry plane of the upper frame 4 and the lower frame 5 is a plane (central plane) located at the center between the upper frame 4 and the lower frame 5, and is orthogonal to the longitudinal direction of the vertical frames 6.

[0016] The left and right vertical frames 6 have the same cross-sectional shape in a cross-section perpendicular to their respective longitudinal directions, and are arranged symmetrically with respect to each other. Furthermore, the left and right vertical frames 6 are made from extruded profiles with the same cross-sectional shape and are formed to the same length. The left and right vertical frames 6 are arranged symmetrically with respect to the plane of symmetry between them. The plane of symmetry between the left and right vertical frames 6 is the plane located in the center between the left and right vertical frames 6 (the central plane), and is perpendicular to the longitudinal direction of the upper frame 4 and the longitudinal direction of the lower frame 5.

[0017] The upper frame 4 and the lower frame 5 each have fixing parts 4A and 5A to which the panel 2 is fixed (see Figure 2). The fixing parts 4A and 5A also each have retaining grooves 4B and 5B for holding the panel 2. The fixing part 4A of the upper frame 4 is integrally formed with the upper frame 4 and protrudes downward. The retaining groove 4B of the fixing part 4A of the upper frame 4 is formed in a concave shape that is recessed upward and opens towards the opening 3A of the lower frame 3. The fixing part 5A of the lower frame 5 is integrally formed with the lower frame 5 and protrudes upward. The retaining groove 5B of the fixing part 5A of the lower frame 5 is formed in a concave shape that is recessed downward and opens towards the opening 3A of the upper frame 3. Panel 2 (upper edge and lower edge) is positioned in the retaining grooves 4B and 5B of the fixing parts 4A and 5A, and is held in the retaining grooves 4B and 5B, and fixed to the fixing parts 4A and 5A, the upper frame 4, and the lower frame 5.

[0018] The joinery 1 comprises two panels 2, one on the left and one on the right, positioned inside the frame 3. The frame 3 also has two openings 3A, one on the left and one on the right, formed on the left and right sides of the mullion 7. The mullion 7 is connected to the upper frame 4 and the lower frame 5, and is erected on the upper frame 4 and the lower frame 5, dividing the inside of the frame 3 (openings 3A) into left and right sections. The panels 2 are positioned in each of the left and right openings 3A of the frame 3. In the left-right direction S, the mullion 7 is positioned between the left and right openings 3A and between the left and right panels 2, holding the left and right panels 2 in place.

[0019] Figure 4 is a cross-sectional view showing a portion of the joinery 1 of the first embodiment that includes the vertical frame 6, and shows one of the left and right vertical frames 6. The other vertical frame 6 of the left and right vertical frames 6 is constructed in the same way as the other vertical frame 6. As shown in the figure, the vertical frame 6 is a divided vertical frame divided in the left-right direction S, and has a first vertical frame member 6A located on the inner circumference side (opening 3A side) of the frame body 3 and a second vertical frame member 6B located on the outer circumference side (opposite side from the opening 3A) of the frame body 3. The first vertical frame member 6A and the second vertical frame member 6B are overlapped in the left-right direction S and connected by screws 6C.

[0020] The frame 3 has two vertical trim pieces 10 and 20 (first vertical trim piece 10, second vertical trim piece 20) attached to the left and right vertical frames 6, respectively. The vertical trim pieces 10 and 20 are trim pieces (vertical frame trim pieces) provided on the vertical frames 6 and are located on the opening 3A side of the frame 3 relative to the vertical frames 6. The first vertical trim piece 10 and the second vertical trim piece 20, when attached to the vertical frames 6, hold the panel 2 (vertical edge portion) between them in the depth direction M1 of the vertical frames 6. Sealing materials 30 and 31 are sandwiched between the vertical trim pieces 10 and 20 and the panel 2. Here, the sealing materials 30 and 31 are gaskets. The panel 2 is sandwiched between the first vertical trim piece 10 and the second vertical trim piece 20 via the sealing materials 30 and 31 and is fixed to the vertical frames 6 by the first vertical trim piece 10 and the second vertical trim piece 20.

[0021] The depth direction M1 of the vertical frame 6 is the direction of the depth dimension of the vertical frame 6 and coincides with the thickness direction T of the joinery 1. The first vertical trim 10 is a one-sided vertical trim located on one side of the depth direction M1 of the vertical frame 6, and the second vertical trim 20 is a other-sided vertical trim located on the other side of the depth direction M1 of the vertical frame 6. The first vertical trim 10 and the second vertical trim 20 are spaced apart and parallel to each other in the depth direction M1 of the vertical frame 6 and extend vertically along the vertical frame 6. The first vertical trim 10 and the second vertical trim 20 are positioned opposite each other in the depth direction M1 of the vertical frame 6, with panel 2 in between them.

[0022] Each of the left and right vertical frames 6 has a vertical projection 6D facing the opening 3A of the frame body 3, and two vertical mounting parts 6E and 6F (first vertical mounting part 6E, second vertical mounting part 6F) provided on the vertical projection 6D. The vertical projection 6D is a projection (vertical frame projection) provided on the vertical frame 6, and is formed in a planar shape without any part that protrudes toward the opening 3A of the frame body 3, and is arranged along the projection direction M1 of the vertical frame 6. The vertical projection 6D is an inner circumference projection located on the inner circumference side of the frame body 3, and defines the opening 3A of the frame body 3. The inner circumference of the frame body 3 is the part that surrounds the opening 3A of the frame body 3, and the inner circumference side of the frame body 3 is the opening 3A side, which is the inside of the frame body 3.

[0023] The vertical mounting sections 6E and 6F are mounting sections (vertical frame mounting sections) provided on the vertical frame 6. The vertical projection section 6D and the vertical mounting sections 6E and 6F are provided on the first vertical frame member 6A of the vertical frame 6. The first vertical trim 10 is fitted and attached to the first vertical mounting section 6E and protrudes from the first vertical mounting section 6E and vertical projection section 6D of the vertical frame 6 toward the opening 3A of the frame body 3. The second vertical trim 20 is fitted and attached to the second vertical mounting section 6F and protrudes from the second vertical mounting section 6F and vertical projection section 6D of the vertical frame 6 toward the opening 3A of the frame body 3.

[0024] The first vertical mounting portion 6E is a one-sided vertical mounting portion located on one side of the vertical frame 6 in the depth direction M1, and the second vertical mounting portion 6F is a other-sided vertical mounting portion located on the other side of the vertical frame 6 in the depth direction M1. The first vertical mounting portion 6E and the second vertical mounting portion 6F are spaced apart and parallel to each other in the depth direction M1 of the vertical frame 6 and extend in the longitudinal direction of the vertical frame 6. The vertical mounting portions 6E and 6F are fitted with the vertical trim pieces 10 and 20, respectively, and hold the vertical trim pieces 10 and 20.

[0025] The first vertical mounting portion 6E and the second vertical mounting portion 6F have the same shape (cross-sectional shape) in a cross-section perpendicular to the longitudinal direction of the vertical frame 6, and are formed symmetrically on the vertical frame 6. The plane of symmetry between the first vertical mounting portion 6E and the second vertical mounting portion 6F is the plane located in the center between the first vertical mounting portion 6E and the second vertical mounting portion 6F, and is perpendicular to the depth direction M1 of the vertical frame 6. Here, the plane of symmetry between the first vertical mounting portion 6E and the second vertical mounting portion 6F is the central plane located in the center in the depth direction M1 of the vertical frame 6. The first vertical mounting portion 6E and the second vertical mounting portion 6F are formed symmetrically on the plane of symmetry between them.

[0026] The first vertical trim 10 and the second vertical trim 20 have the same cross-sectional shape in a cross section perpendicular to their respective longitudinal directions, and are arranged symmetrically with respect to each other. Furthermore, the first vertical trim 10 and the second vertical trim 20 are made from the same cross-sectional shape (extruded profile) and are formed to the same length. The plane of symmetry between the first vertical trim 10 and the second vertical trim 20 is the plane located in the center between them, and is perpendicular to the depth direction M1 of the vertical frame 6. Here, the plane of symmetry between the first vertical trim 10 and the second vertical trim 20 is the central plane located in the depth direction M1 of the vertical frame 6. The first vertical trim 10 and the second vertical trim 20 are arranged symmetrically with respect to the plane of symmetry between them.

[0027] The first vertical trim 10 has a fitting portion 11 that fits into and attaches to the first vertical mounting portion 6E of the vertical frame 6. The second vertical trim 20 has a fitting portion 21 that fits into and attaches to the second vertical mounting portion 6F of the vertical frame 6. The fitting portions 11 and 21 are vertical fitting portions provided on the vertical trims 10 and 20, and are located at the ends of the vertical trims 10 and 20 on the vertical frame 6 side. Without the use of other members (e.g., mounting fixtures), the fitting portion 11 of the first vertical trim 10 fits directly into and attaches to the first vertical mounting portion 6E, thereby directly attaching the first vertical trim 10 to the first vertical mounting portion 6E. Similarly, without the use of other members, the fitting portion 21 of the second vertical trim 20 fits directly into and attaches to the second vertical mounting portion 6F, thereby directly attaching the second vertical trim 20 to the second vertical mounting portion 6F.

[0028] The first vertical mounting portion 6E of the vertical frame 6 is a fitting groove into which the fitting portion 11 of the first vertical trim 10 is pressed and fitted. The second vertical mounting portion 6F of the vertical frame 6 is a fitting groove into which the fitting portion 21 of the second vertical trim 20 is pressed and fitted. The vertical mounting portions 6E and 6F, which are fitting grooves, are vertical fitting grooves (first vertical fitting groove and second vertical fitting groove) provided in the vertical frame 6, and are formed in a concave shape that is recessed toward the inside side of the vertical frame 6 (outer circumference side of the frame body 3) relative to the vertical projection portion 6D, and are open toward the opening 3A of the frame body 3.

[0029] The fitting portion 11 of the first vertical trim 10 is pushed into the first vertical mounting portion 6E (fitting groove) from the opening 3A side of the frame 3 while undergoing elastic deformation, and is positioned inside the first vertical mounting portion 6E. The fitting portion 11 of the first vertical trim 10 recovers from elastic deformation inside the first vertical mounting portion 6E and fits into the first vertical mounting portion 6E. The fitting portion 21 of the second vertical trim 20 is pushed into the second vertical mounting portion 6F (fitting groove) from the opening 3A side of the frame 3 while undergoing elastic deformation, and is positioned inside the second vertical mounting portion 6F. The fitting portion 21 of the second vertical trim 20 recovers from elastic deformation inside the second vertical mounting portion 6F and fits into the second vertical mounting portion 6F.

[0030] The first vertical mounting portion 6E has a groove bottom 6G located at the bottom of the fitting groove and a pair of groove walls 6H projecting from the groove bottom 6G toward the opening 3A of the frame 3. The pair of groove walls 6H are positioned apart from each other in the depth direction M1 of the vertical frame 6, and are formed to gradually approach each other from the groove bottom 6G toward the opening 3A of the frame 3, projecting toward the inside of the fitting groove, the first vertical mounting portion 6E. The second vertical mounting portion 6F has a groove bottom 6I located at the bottom of the fitting groove and a pair of groove walls 6J projecting from the groove bottom 6I toward the opening 3A of the frame 3. The pair of groove walls 6J are positioned apart from each other in the depth direction M1 of the vertical frame 6, and are formed to gradually approach each other from the groove bottom 6I toward the opening 3A of the frame 3, projecting toward the inside of the fitting groove, the second vertical mounting portion 6F. Therefore, the groove width of the vertical mounting portions 6E and 6F in the depth direction M1 of the vertical frame 6 gradually narrows from the groove bottoms 6G and 6I toward the opening 3A of the frame body 3.

[0031] The fitting portion 11 of the first vertical trim 10 consists of two hook-shaped locking portions spaced apart in the depth direction M1 of the vertical frame 6, and is hooked onto a pair of groove walls 6H inside the first vertical mounting portion 6E. As a result, the fitting portion 11 of the first vertical trim 10 fits into the pair of groove walls 6H and the first vertical mounting portion 6E. The fitting portion 21 of the second vertical trim 20 consists of two hook-shaped locking portions spaced apart in the depth direction M1 of the vertical frame 6, and is hooked onto a pair of groove walls 6J inside the second vertical mounting portion 6F. As a result, the fitting portion 21 of the second vertical trim 20 fits into the pair of groove walls 6J and the second vertical mounting portion 6F.

[0032] The frame 3 has a waterproofing material 32 that extends in the longitudinal direction of the vertical frame 6. The waterproofing material 32 is provided in at least one (either one or both) of the space between the first vertical mounting portion 6E and the fitting portion 11 of the first vertical trim 10, and between the second vertical mounting portion 6F and the fitting portion 21 of the second vertical trim 20. Here, the waterproofing material 32 is positioned inside the first vertical mounting portion 6E and provided between the first vertical mounting portion 6E and the fitting portion 11 of the first vertical trim 10. The waterproofing material 32 is, for example, a waterproofing sheet, a watertight material, or a sponge, and is attached to the groove bottom 6G of the first vertical mounting portion 6E. The waterproofing material 32 is sandwiched between the first vertical mounting portion 6E (groove bottom 6G) and the fitting portion 11 of the first vertical trim 10, and waterproofs the space between the first vertical mounting portion 6E and the fitting portion 11 of the first vertical trim 10.

[0033] Figure 5 is a cross-sectional view showing the connection between the lower frame 5 (upper frame 4) and the vertical frame 6 in the joinery 1 of the first embodiment. As shown in the figure, the upper frame 4 and the lower frame 5 are positioned with their respective ends 4C and 5C facing the vertical projection 6D of the vertical frame 6, and are connected to the vertical projection 6D. The end 4C of the upper frame 4 is the end of the upper frame 4 in the longitudinal direction, and the end 5C of the lower frame 5 is the end of the lower frame 5 in the longitudinal direction. In the left and right vertical frames 6, the end 4C of the upper frame 4 and the end 5C of the lower frame 5 are positioned facing the vertical projection 6D and the vertical mounting parts 6E and 6F, respectively, and abut against the vertical projection 6D. In this state, the upper frame 4 is connected to the vertical projection 6D and the vertical frame 6 (upper end), and the lower frame 5 is connected to the vertical projection 6D and the vertical frame 6 (lower end).

[0034] The frame 3 has sealing members 40 and 41 that close the first vertical mounting portion 6E (fitting groove) and the second vertical mounting portion 6F (fitting groove). The sealing members 40 and 41 are vertical sealing members (first vertical sealing member and second vertical sealing member) attached to the vertical mounting portions 6E and 6F, and are positioned inside the vertical mounting portions 6E and 6F. The sealing members 40 and 41 are also filling materials that fill the vertical mounting portions 6E and 6F, and are, for example, resin sealing members, metal sealing members (such as aluminum alloy sealing members), or sealing materials. The sealing members 40 and 41 close the first vertical mounting portion 6E and the second vertical mounting portion 6F located at the points in the vertical projection portion 6D that face the end 4C of the upper frame 4 and the points that face the end 5C of the lower frame 5, respectively.

[0035] The first vertical mounting section 6E (fitting groove) and the second vertical mounting section 6F (fitting groove) are sealed by sealing materials 40 and 41 at the locations facing the end 4C of the upper frame 4 and the end 5C of the lower frame 5, respectively. The sealing materials 40 and 41 are inserted into the first vertical mounting section 6E and the second vertical mounting section 6F, filling the first vertical mounting section 6E and the second vertical mounting section 6F. Of the two sealing materials 40 and 41, one sealing material 40 seals the first vertical mounting section 6E and is sandwiched between the first vertical mounting section 6E and the end 4C of the upper frame 4, and between the first vertical mounting section 6E and the end 5C of the lower frame 5. Furthermore, the other sealing member 41 blocks the second vertical mounting portion 6F and is sandwiched between the second vertical mounting portion 6F and the end portion 4C of the upper frame 4, and between the second vertical mounting portion 6F and the end portion 5C of the lower frame 5.

[0036] Figure 6 is a cross-sectional view showing a portion of the door / window 1 in the first embodiment that includes the mullion 7. As shown in the figure, the mullion 7 is a divided mullion divided in the left-right direction S, and has a first mullion member 7A located on one side in the left-right direction S and a second mullion member 7B located on the other side in the left-right direction S. The first mullion member 7A and the second mullion member 7B are overlapped in the left-right direction S and connected by screws 7C. A watertight material 8 is provided at one end of the mullion 7 in the depth direction M2. The watertight material 8 is provided along the entire longitudinal direction of the mullion 7 and is sandwiched between the first mullion member 7A and the second mullion member 7B.

[0037] The left and right panels 2 of the mullion 7 are positioned in the left and right openings 3A of the mullion 7 and are fixed to the mullion 7. The frame 3 has two mullion trims 50 and 60 (first mullion trim 50 and second mullion trim 60) attached to the mullion 7 on each of the left and right sides of the mullion 7. The mullion trims 50 and 60 are trims provided on the mullion 7 and are located on the left and right openings 3A side of the frame 3 relative to the mullion 7.

[0038] On both the left and right sides of the mullion 7, the first mullion trim 50 and the second mullion trim 60 are attached to the mullion 7 and hold the panel 2 (vertical edge portion) between them in the depth direction M2 of the mullion 7. Sealing materials 33 and 34 are sandwiched between the mullion trims 50 and 60 and the panel 2. Here, the sealing materials 33 and 34 are gaskets. The panel 2 is sandwiched between the first mullion trim 50 and the second mullion trim 60 via the sealing materials 33 and 34 and is fixed to the mullion 7 by the first mullion trim 50 and the second mullion trim 60.

[0039] The depth direction M2 of the mullion 7 is the direction of the depth dimension of the mullion 7 and coincides with the thickness direction T of the joinery 1. The first mullion trim 50 is a one-sided mullion trim located on one side of the depth direction M2 of the mullion 7, and the second mullion trim 60 is a other-sided mullion trim located on the other side of the depth direction M2 of the mullion 7. The first mullion trim 50 and the second mullion trim 60 are spaced apart and parallel to each other in the depth direction M2 of the mullion 7 and extend vertically along the mullion 7. The first mullion trim 50 and the second mullion trim 60 are positioned opposite each other in the depth direction M2 of the mullion 7, with panel 2 in between them.

[0040] The mullion 7 has left and right mullion projections 7D facing the left and right openings 3A of the frame 3, and two mullion mounting parts 7E and 7F (first mullion mounting part 7E, second mullion mounting part 7F) provided on each of the left and right mullion projections 7D. The left and right mullion projections 7D are projections provided on the mullion 7, and are formed in a planar shape without any parts protruding toward the openings 3A of the frame 3, and are arranged along the projection direction M2 of the mullion 7. The mullion projections 7D are also inner circumference projections located on the inner circumference side of the frame 3, and define the openings 3A of the frame 3. The inner circumference of the frame 3 is the part that surrounds each of the left and right openings 3A of the frame 3, and the inner circumference side of the frame 3 is the opening 3A side, which is the inside of the frame 3.

[0041] The mullion mounting sections 7E and 7F are mounting sections provided on the mullion 7. The mullion projection section 7D and the mullion mounting sections 7E and 7F are provided on the first mullion member 7A and the second mullion member 7B of the mullion 7, respectively. On each of the left and right mullion projection sections 7D of the mullion 7, the first mullion trim 50 is fitted and attached to the first mullion mounting section 7E, and protrudes from the first mullion mounting section 7E and the mullion projection section 7D of the mullion 7 toward the opening 3A of the frame 3. The second mullion trim 60 is fitted and attached to the second mullion mounting section 7F, and protrudes from the second mullion mounting section 7F and the mullion projection section 7D of the mullion 7 toward the opening 3A of the frame 3.

[0042] The first mullion mounting portion 7E is a one-sided mullion mounting portion located on one side of the mullion 7 in the depth direction M2, and the second mullion mounting portion 7F is a other-sided mullion mounting portion located on the other side of the mullion 7 in the depth direction M2. The first mullion mounting portion 7E and the second mullion mounting portion 7F are spaced apart in the depth direction M2 of the mullion 7 and are parallel to each other, extending in the longitudinal direction of the mullion 7. The mullion mounting portions 7E and 7F are fitted with the mullion trims 50 and 60, respectively, and hold the mullion trims 50 and 60.

[0043] The first mullion mounting portion 7E and the second mullion mounting portion 7F have the same shape (cross-sectional shape) in a cross-section perpendicular to the longitudinal direction of the mullion 7, and are formed symmetrically with respect to the mullion 7. The plane of symmetry between the first mullion mounting portion 7E and the second mullion mounting portion 7F is the plane located in the center between the first mullion mounting portion 7E and the second mullion mounting portion 7F, and is perpendicular to the depth direction M2 of the mullion 7. Here, the plane of symmetry between the first mullion mounting portion 7E and the second mullion mounting portion 7F is the central plane located in the center in the depth direction M2 of the mullion 7. The first mullion mounting portion 7E and the second mullion mounting portion 7F are formed symmetrically with respect to the plane of symmetry between them.

[0044] The first mullion trim 50 and the second mullion trim 60 have the same cross-sectional shape in a cross section perpendicular to their respective longitudinal directions, and are arranged symmetrically with respect to each other. Furthermore, the first mullion trim 50 and the second mullion trim 60 are made from the same cross-sectional shape (extruded profile) and are formed to the same length. The plane of symmetry between the first mullion trim 50 and the second mullion trim 60 is the plane located in the center between them, and is perpendicular to the depth direction M2 of the mullion 7. Here, the plane of symmetry between the first mullion trim 50 and the second mullion trim 60 is the central plane located in the center of the depth direction M2 of the mullion 7. The first mullion trim 50 and the second mullion trim 60 are arranged symmetrically with respect to the plane of symmetry between them.

[0045] The first mullion trim 50 has a fitting portion 51 that fits into and attaches to the first mullion mounting portion 7E of the mullion 7. The second mullion trim 60 has a fitting portion 61 that fits into and attaches to the second mullion mounting portion 7F of the mullion 7. The fitting portions 51 and 61 are mullion fitting portions provided on the mullion trims 50 and 60, and are located at the ends of the mullion trims 50 and 60 on the mullion 7 side. Without the use of other members, the fitting portion 51 of the first mullion trim 50 fits directly into and attaches to the first mullion mounting portion 7E, thereby directly attaching the first mullion trim 50 to the first mullion mounting portion 7E. Similarly, without the use of other members, the fitting portion 61 of the second mullion trim 60 fits directly into and attaches to the second mullion mounting portion 7F, thereby directly attaching the second mullion trim 60 to the second mullion mounting portion 7F.

[0046] The first mullion mounting portion 7E of the mullion 7 is a fitting groove into which the fitting portion 51 of the first mullion trim 50 is pressed and fitted. The second mullion mounting portion 7F of the mullion 7 is a fitting groove into which the fitting portion 61 of the second mullion trim 60 is pressed and fitted. The fitting grooves, the mullion mounting portions 7E and 7F, are mullion fitting grooves (first mullion fitting groove and second mullion fitting groove) provided on the mullion 7, and are formed in a concave shape that is recessed toward the inside of the mullion 7 relative to the mullion projection portion 7D, and are open toward the opening 3A of the frame 3.

[0047] The fitting portion 51 of the first vertical trim 50 is pushed into the first vertical mounting portion 7E (fitting groove) from the opening 3A side of the frame 3 while undergoing elastic deformation, and is positioned inside the first vertical mounting portion 7E. The fitting portion 51 of the first vertical trim 50 recovers from elastic deformation inside the first vertical mounting portion 7E and fits into the first vertical mounting portion 7E. The fitting portion 61 of the second vertical trim 60 is pushed into the second vertical mounting portion 7F (fitting groove) from the opening 3A side of the frame 3 while undergoing elastic deformation, and is positioned inside the second vertical mounting portion 7F. The fitting portion 61 of the second vertical trim 60 recovers from elastic deformation inside the second vertical mounting portion 7F and fits into the second vertical mounting portion 7F.

[0048] The first mullion mounting portion 7E has a groove bottom 7G located at the bottom of the fitting groove and a pair of groove walls 7H projecting from the groove bottom 7G toward the opening 3A of the frame 3. The pair of groove walls 7H are positioned apart from each other in the depth direction M2 of the mullion 7, and are formed to gradually approach each other from the groove bottom 7G toward the opening 3A of the frame 3, projecting toward the inside of the fitting groove, the first mullion mounting portion 7E. The second mullion mounting portion 7F has a groove bottom 7I located at the bottom of the fitting groove and a pair of groove walls 7J projecting from the groove bottom 7I toward the opening 3A of the frame 3. The pair of groove walls 7J are positioned apart from each other in the depth direction M2 of the mullion 7, and are formed to gradually approach each other from the groove bottom 7I toward the opening 3A of the frame 3, projecting toward the inside of the fitting groove, the second mullion mounting portion 7F. Therefore, the groove width of the mullion mounting portions 7E and 7F in the depth direction M2 of the mullion 7 gradually narrows from the groove bottoms 7G and 7I toward the opening 3A of the frame 3.

[0049] The fitting portion 51 of the first mullion trim 50 consists of two hook-shaped locking portions spaced apart in the depth direction M2 of the mullion 7, and is hooked and locked onto a pair of grooved walls 7H inside the first mullion mounting portion 7E. As a result, the fitting portion 51 of the first mullion trim 50 fits onto the pair of grooved walls 7H and the first mullion mounting portion 7E. The fitting portion 61 of the second mullion trim 60 consists of two hook-shaped locking portions spaced apart in the depth direction M2 of the mullion 7, and is hooked and locked onto a pair of grooved walls 7J inside the second mullion mounting portion 7F. As a result, the fitting portion 61 of the second mullion trim 60 fits onto the pair of grooved walls 7J and the second mullion mounting portion 7F.

[0050] The frame 3 has a waterproofing material 35 that extends in the longitudinal direction of the mullion 7. The waterproofing material 35 is provided in at least one (either one or both) of the following locations: between the first mullion mounting portion 7E and the fitting portion 51 of the first mullion trim 50, and between the second mullion mounting portion 7F and the fitting portion 61 of the second mullion trim 60. Here, the waterproofing material 35 is positioned inside the first mullion mounting portion 7E and provided between the first mullion mounting portion 7E and the fitting portion 51 of the first mullion trim 50. The waterproofing material 35 is, for example, a waterproofing sheet, a watertight material, or a sponge, and is attached to the bottom of the groove 7G of the first mullion mounting portion 7E. The waterproofing material 35 is sandwiched between the first vertical mounting portion 7E (groove bottom 7G) and the fitting portion 51 of the first vertical trim 50, thereby waterproofing the area between the first vertical mounting portion 7E and the fitting portion 51 of the first vertical trim 50.

[0051] Figure 7 is a cross-sectional view showing the connection between the lower frame 5 (upper frame 4) and the mullion 7 in the joinery 1 of the first embodiment. As shown in the figure, the upper frame 4 and the lower frame 5 are provided on both the left and right sides of the mullion 7. The left and right upper frames 4 connect to the mullion 7 with the mullion 7 in between them, and the left and right lower frames 5 connect to the mullion 7 with the mullion 7 in between them. At each of the left and right mullion projections 7D of the mullion 7, the ends 4C and 5C of the upper frame 4 and the lower frame 5 are positioned opposite the mullion projection 7D of the mullion 7 and connect to the mullion projection 7D. The ends 4C of the upper frame 4 and the ends 5C of the lower frame 5 are positioned opposite the mullion projection 7D and the mullion mounting parts 7E and 7F, respectively, and abut against the mullion projection 7D. In this state, the upper frame 4 is connected to the mullion projection 7D and the mullion 7 (upper end), and the lower frame 5 is connected to the mullion projection 7D and the mullion 7 (lower end).

[0052] The frame 3 has sealing members 42 and 43 that close the first mullion mounting portion 7E (fitting groove) and the second mullion mounting portion 7F (fitting groove). The sealing members 42 and 43 are mullion sealing members (first mullion sealing member and second mullion sealing member) attached to the mullion mounting portions 7E and 7F, and are positioned inside the mullion mounting portions 7E and 7F. The sealing members 42 and 43 are also filling materials that fill the mullion mounting portions 7E and 7F, and are, for example, resin sealing members, metal sealing members (such as aluminum alloy sealing members), or sealing materials. The sealing members 42 and 43 close the first mullion mounting portion 7E and the second mullion mounting portion 7F located at the locations in the mullion projection portion 7D that face the end portion 4C of the upper frame 4 and the location that faces the end portion 5C of the lower frame 5, respectively.

[0053] The first mullion mounting section 7E (fitting groove) and the second mullion mounting section 7F (fitting groove) are sealed by sealing materials 42 and 43 at the locations facing the end 4C of the upper frame 4 and the end 5C of the lower frame 5, respectively. The sealing materials 42 and 43 are inserted into the first mullion mounting section 7E and the second mullion mounting section 7F, filling the first mullion mounting section 7E and the second mullion mounting section 7F. Of the two sealing materials 42 and 43, one sealing material 42 seals the first mullion mounting section 7E and is sandwiched between the first mullion mounting section 7E and the end 4C of the upper frame 4, and between the first mullion mounting section 7E and the end 5C of the lower frame 5. Furthermore, the other blocking material 43 blocks the second mullion mounting portion 7F and is sandwiched between the second mullion mounting portion 7F and the end portion 4C of the upper frame 4, and between the second mullion mounting portion 7F and the end portion 5C of the lower frame 5.

[0054] In the joinery 1 described above, the fitting portions 11 and 21 of the vertical trim pieces 10 and 20 are fitted to the vertical mounting portions 6E and 6F of the vertical frame 6, respectively, allowing the vertical trim pieces 10 and 20 to be easily attached to the vertical frame 6 and improving the workability of fixing the panel 2 with the vertical trim pieces 10 and 20. In addition, the fitting portions 51 and 61 of the mullion trim pieces 50 and 60 are fitted to the mullion mounting portions 7E and 7F of the mullion 7, respectively, allowing the mullion trim pieces 50 and 60 to be easily attached to the mullion 7 and improving the workability of fixing the panel 2 with the mullion trim pieces 50 and 60.

[0055] By pushing the fitting portions 11 and 21 of the vertical trim pieces 10 and 20 into the fitting grooves, which are the vertical mounting portions 6E and 6F, the vertical trim pieces 10 and 20 can be easily attached to the vertical mounting portions 6E and 6F. Since the fitting portions 11 and 21 of the vertical trim pieces 10 and 20 are positioned inside the vertical mounting portions 6E and 6F, it is possible to keep the protruding dimension of the vertical trim pieces 10 and 20 small while ensuring the necessary protrusion dimension of the vertical trim pieces 10 and 20 from the vertical projection portion 6D required for holding the panel 2. As a result, the visible dimension obtained by adding the dimensions of the vertical frame 6 and the vertical trim pieces 10 and 20 in the visible direction (left-right direction S) of the vertical frame 6 can be kept small, making the vertical frame 6 and vertical trim pieces 10 and 20 slimmer when the joinery 1 is viewed from the front.

[0056] By pushing the fitting portions 51, 61 of the mullion trim 50, 60 into the fitting grooves, which are the mullion mounting portions 7E, 7F, the mullion trim 50, 60 can be easily attached to the mullion mounting portions 7E, 7F. Since the fitting portions 51, 61 of the mullion trim 50, 60 are positioned inside the mullion mounting portions 7E, 7F, it is possible to keep the protruding dimension of the mullion trim 50, 60 small while ensuring the necessary protrusion dimension of the mullion trim 50, 60 from the mullion projection portion 7D required for holding the panel 2. As a result, the visible dimension obtained by adding the dimensions of the mullion 7 and the left and right mullion trims 50, 60 in the visible direction of the mullion 7 (left and right direction S) can be kept small, making the mullion 7 and the left and right mullion trims 50, 60 slimmer when the joinery 1 is viewed from the front.

[0057] The sealing materials 40 and 41 block the fitting grooves of the vertical mounting portions 6E and 6F of the vertical frame 6, preventing water from entering the fitting grooves and improving the watertightness of the frame 3. The watertight material 32 seals the area between the first vertical mounting portion 6E of the vertical frame 6 and the fitting portion 11 of the first vertical trim 10, preventing water from passing through the area between the first vertical mounting portion 6E and the fitting portion 11 in the depth direction M1 of the vertical frame 6. The first vertical trim 10 and the second vertical trim 20 have the same shape in a cross section perpendicular to their respective longitudinal directions and are arranged symmetrically with respect to each other. Therefore, the same vertical trim can be used for the first vertical trim 10 and the second vertical trim 20, and the types of vertical trims 10 and 20 provided in the joinery 1 can be limited to one type.

[0058] The sealing materials 42 and 43 block the fitting grooves of the mullion mounting portions 7E and 7F of the mullion 7, preventing water from entering the fitting grooves and improving the watertightness of the frame 3. The watertight material 35 seals the area between the first mullion mounting portion 7E of the mullion 7 and the fitting portion 51 of the first mullion trim 50, preventing water from passing through the area between the first mullion mounting portion 7E and the fitting portion 51 in the depth direction M2 of the mullion 7. The first mullion trim 50 and the second mullion trim 60 have the same shape in a cross section perpendicular to their respective longitudinal directions and are arranged symmetrically with respect to each other. Therefore, the same mullion trim can be used for both the first mullion trim 50 and the second mullion trim 60, and the number of types of mullion trims 50 and 60 provided in the joinery 1 can be reduced to one type.

[0059] Alternatively, one or more transoms may be provided on the frame 3 to divide the opening 3A of the frame 3 vertically. The transom is a horizontal member extending horizontally, located between the upper frame 4 and the lower frame 5, and is installed on the vertical frame 6 and the mullion 7. The panel 2 is fixed and held in place by the transom.

[0060] Alternatively, without providing mullions 7 on the frame 3, one panel 2 may be placed in one opening 3A of the frame 3. If a transom is provided on a frame 3 that does not have mullions 7, the transom is located between the left and right vertical frames 6 and is installed on the left and right vertical frames 6. In contrast, multiple mullions 7 may be provided on the frame 3, and multiple panels 2 may be placed in multiple openings 3A of the frame 3. If a transom is provided on a frame 3 that has multiple mullions 7, the transom is located between the vertical frames 6 and the mullions 7 and is installed on the vertical frames 6 and the mullions 7, as well as located between the left and right mullions 7 and is installed on the left and right mullions 7.

[0061] (Second Embodiment) Next, the second embodiment of the joinery 1 will be described. In the second embodiment of the joinery 1, the same matters as those described in the first embodiment of the joinery 1 will be omitted, and the differences from the first embodiment of the joinery 1 will be mainly described. Furthermore, with respect to the second embodiment of the joinery 1, the same names and reference numerals as those used for the configuration of the first embodiment of the joinery 1 will be used for the configuration corresponding to the configuration of the first embodiment of the joinery 1.

[0062] Figure 8 is a vertical cross-sectional view of the joinery 1 of the second embodiment, showing the joinery 1 cut by a plane that includes the vertical direction R and the thickness direction T of the joinery 1. As shown in the diagram, the fixing portion 4A of the upper frame 4 does not protrude downwards, and the fixing portion 5A of the lower frame 5 does not protrude upwards.

[0063] The upper frame 4 has an upper projection 4D facing the opening 3A of the frame 3 and an upper fixing groove 4E to which an anchor (not shown) is fixed. The upper projection 4D is a projection (upper frame projection) provided on the upper frame 4, and is formed in a planar shape without any part protruding toward the opening 3A of the frame 3, and is arranged along the projection direction of the upper frame 4 (thickness direction T of the joinery 1). The upper fixing groove 4E is located on the outer circumference (upper side) of the upper frame 4. The anchor is fixed to the building structure, and the upper frame 4 is attached to the building structure via the anchor.

[0064] The lower frame 5 has a lower projection 5D facing the opening 3A of the frame 3 and a lower fixing groove 5E to which an anchor (not shown) is fixed. The lower projection 5D is a projection (lower frame projection) provided on the lower frame 5, and is formed in a planar shape without any part protruding toward the opening 3A of the frame 3, and is arranged along the projection direction of the lower frame 5 (thickness direction T of the joinery 1). The lower fixing groove 5E is located on the outer circumference (lower side) of the lower frame 5. The anchor is fixed to the building structure, and the lower frame 5 is attached to the building structure via the anchor.

[0065] Figure 9 is a cross-sectional view of the joinery 1 of the second embodiment, showing the joinery 1 cut by a plane including the left-right direction S and the thickness direction T of the joinery 1. Figure 10 is a cross-sectional view of the portion of the joinery 1 of the second embodiment that includes the vertical frame 6, showing one of the left and right vertical frames 6. Figure 11 is a cross-sectional view of the portion of the joinery 1 of the second embodiment that includes the mullion 7.

[0066] As shown in the figure, the vertical frame 6 is not divided in the left-right direction S, but consists of a single vertical frame member. The vertical frame 6 also has a vertical fixing groove 6K to which an anchor (not shown) is fixed. The vertical fixing groove 6K is located on the outer circumference side of the vertical frame 6. The anchor is fixed to the building's structure, and the vertical frame 6 is attached to the building's structure via the anchor. The vertical frame 6 is formed symmetrically with respect to the central surface located in the center in the depth direction M1 of the vertical frame 6.

[0067] The sealants 30 and 31 between the vertical trim pieces 10 and 20 and the panel 2 consist of irregularly shaped sealants, supported by backup materials 36 and 37, and filled between the vertical trim pieces 10 and 20 and the panel 2. The backup materials 36 and 37 are sandwiched between the vertical trim pieces 10 and 20 and the panel 2. The sealants 33 and 34 between the vertical trim pieces 50 and 60 and the panel 2 consist of irregularly shaped sealants, supported by backup materials 38 and 39, and filled between the vertical trim pieces 50 and 60 and the panel 2. The backup materials 38 and 39 are sandwiched between the vertical trim pieces 50 and 60 and the panel 2.

[0068] Figure 12 is a cross-sectional view showing another example of the vertical frame 6 in the joinery 1 of the second embodiment. As shown in the figure, the joinery 1 here is equipped with a position adjustment mechanism 70 for adjusting the position of the vertical frame 6 in the left-right direction S. The vertical frame 6 is attached to the building's structure 9 by the position adjustment mechanism 70 instead of anchors. The position adjustment mechanism 70 has a base material 71 fixed to the structure 9 and a connecting member 72 positioned inside the vertical frame 6 and fixed to the vertical frame 6. The base material 71 has a pair of guide portions 71A spaced apart in the depth direction M1 of the vertical frame 6. The pair of guide portions 71A protrude from the structure 9 toward the vertical frame 6, are positioned along the left-right direction S, and face each other in the depth direction M1 of the vertical frame 6.

[0069] The connecting member 72 has a pair of sliding parts 72A spaced apart in the depth direction M1 of the vertical frame 6. The pair of sliding parts 72A protrude from the vertical frame 6 toward the building structure 9, are arranged along the left-right direction S, and face each other in the depth direction M1 of the vertical frame 6. The pair of sliding parts 72A of the connecting member 72 are located between a pair of guide parts 71A of the base material 71, and each contacts the guide part 71A and slides along the guide part 71A in the left-right direction S. The base material 71 guides and moves the pair of sliding parts 72A and the connecting member 72 in the left-right direction S by the pair of guide parts 71A. The pair of sliding parts 72A, the connecting member 72, and the vertical frame 6 move in the left-right direction S while being guided by the base material 71.

[0070] The connecting member 72 and the vertical frame 6 are moved in the left-right direction S along a pair of guide portions 71A of the base material 71, corresponding to the dimensions S of the opening in the building. This adjusts the position of the vertical frame 6 in the left-right direction S. In this state, the pair of sliding portions 72A of the connecting member 72 are attached to the pair of guide portions 71A of the base material 71 using screws 73. This attaches the connecting member 72 to the base material 71. The vertical frame 6 is connected to the base material 71 by the connecting member 72 and attached to the building frame 9 via the connecting member 72 and the base material 71.

[0071] As described above, this embodiment discloses the joinery described in (1) to (7) below.
