Summary of the Invention

Problems to be Solved by the Invention

[0004] In a fitting, by disposing a backbone-shaped member such as a plain surface or a vertical rib inside the frame, a stepped window or a continuous window in which facing materials are disposed in different support forms inside one frame may be configured. For example, in the case of a stepped window, by providing a plain surface inside the frame, an opening window can be configured above the plain surface, while a FIX window can be configured below the plain surface.

[0005] In this type of fitting, a reference molded part having a common cross-sectional shape above and below the plain surface is applied as the metal molded part of the vertical frame, and attachment molded parts corresponding to the support forms of the respective facing materials are attached on the upper side and the lower side of the plain surface in the reference molded part. In such fittings, even when there are many types of support forms of the facing materials, it is possible to cope with using a common reference molded part by changing the attachment molded part to be applied.

[0006] In this context, it is desirable to share as many parts as possible among building components in the same product series. Therefore, even between a single window with only a facing material attached to the frame and the aforementioned stepped window, it is preferable to share the resin molded parts among those where the support configuration for the facing material is the same.

[0007] However, the attachment molding part and the resin molding part need to be attached to the base molding part with the mullions connected. For this reason, it is not possible to crimp the resin molding part to the base molding part, and this has not yet been realized. In other words, when constructing a single window frame, both ends of the resin molding part are positioned close to the open end faces of the metal molding part. Therefore, after inserting the crimping part of the resin frame part into the insertion part of the metal molding part, it is possible to easily crimp the metal molding part and the resin molding part by inserting a crimping press device from both ends of the metal molding part. However, when constructing a frame for a stepped window or a series of windows, one end of the resin molding part is positioned close to the mullions or other structural members, so it is not possible to position a crimping press device on this end of the resin molding part, making it difficult to crimp the base molding part and the resin molding part.

[0008] In view of the above circumstances, the present invention makes it possible to apply the resin molded part that is applied to single windows to stepped windows and connected windows as well. Doors and windows The purpose is to provide. [Means for solving the problem]

[0009] To achieve the above objective, the joinery according to the present invention comprises a central frame material constituting the frame body, which includes a metal frame portion formed from metal, and an upper resin frame portion, a lower resin frame portion, and a cover resin frame portion formed from resin. The cover resin frame portion covers the metal frame portion between the upper resin frame portion and the lower resin frame portion, and the metal frame portion has an upper resin frame insertion portion and a lower resin frame insertion portion in the portion located on the interior side, the upper resin frame portion has an upper insertion fin portion that is inserted into the upper resin frame insertion portion, and the lower resin frame portion has an inward insertion fin portion that is inserted into the lower resin frame insertion portion, and the upper resin frame portion and the lower resin frame portion are provided with an upper resin frame body and a mounting plate portion that face each other. The aforementioned cover resin frame portion is The upper resin frame body and the mounting plate portion have two joints positioned between them, one of which is above the upper resin frame insertion portion and faces the upper insertion fin portion in the depth direction, and is attached to the upper resin frame body in a non-contact state from the metal frame portion, and the other joint is below the lower resin frame insertion portion and faces the inner insertion fin portion in the depth direction, and is attached to the mounting plate portion in a non-contact state from the metal frame portion. It is characterized by being attached to something. [Effects of the Invention]

[0012] According to the present invention, the resin molded portion is provided with a first crimping portion and a second crimping portion. Therefore, the resin molded portion can be pre-crimped to the attachment molded portion via the first crimping portion with respect to the first metal molded portion, and the resin molded portion can also be attached to the reference molded portion with the central frame profile already attached. On the other hand, the resin molded portion can be crimped to the second metal molded portion via the second crimping portion. As a result, the same resin molded portion can be applied to stepped windows and connected windows to which the first metal molded portion is applied, and to single windows to which the second metal molded portion is applied, thereby enabling the sharing of parts.

The inner upper resin frame insertion portion 315c is a groove-shaped section provided on the interior-facing edge of the metal frame body 315a, and is formed to open toward the inner circumference. The position in which the inner upper resin frame insertion portion 315c is provided relative to the metal frame body 315a is the same as the position in which the resin frame insertion portion 215e is provided relative to the metal frame body 215a in the metal frame portion 215 of Embodiment 1. The inner accommodating groove forming piece 315d extends toward the inner circumference in the facing direction from a position approximately in the center of the depth direction of the metal frame body 315a, and then bends toward the exterior. The extended dimension of the inner accommodating groove forming piece 315d is shorter than the extended dimension of the upper outer panel support portion 315b. The intermediate upper resin frame insertion portion 315e is provided at a position approximately in the center of the interior-facing facing surface of the inner accommodating groove forming piece 315d, and is formed to open toward the inner circumference. As is clear from the figure, a hollow space is provided between the upper outer panel support portion 315b and the inner housing groove forming piece 315d by an inner circumferential facing wall portion 315g that is aligned in the facing direction. The inner circumferential facing wall portion 315g is located at a position approximately midway between the inner edge of the inner housing groove forming piece 315d and the intermediate upper resin frame insertion portion 315e, and has a retaining edge engaging portion 315h on the facing surface on the inner circumferential side. The retaining edge engaging portion 315h protrudes inward from the inner circumferential facing wall portion 315g and then bends inward, ensuring a gap between it and the inner circumferential facing wall portion 315g.

[0033] The resin frame portion (resin molded portion) 316 of the vertical frame 33 covers the portion of the metal frame portion 315 that is on the indoor side of the inward-facing groove forming piece 315d, and has a resin frame body 316a, an outward insertion fin portion (first crimping portion) 316b, an inward insertion fin portion (second crimping portion) 316c, a mounting plate portion 316d, and an opposing projection portion 316e. The resin frame body 316a has a hollow rectangular cross-section that is horizontally elongated in the depth direction. The outward insertion fin portion 316b is inserted into the intermediate upper resin frame insertion portion 315e, and extends outward in the depth direction from the outer edge of the resin frame body 316a, which is on the outdoor side and outer circumference, and then bends outward. The inward insertion fin portion 316c is inserted into the inner upper resin frame insertion portion 315c of the metal frame portion 315, and is bent outward from the edge on the indoor side and outer circumference of the resin frame body 316a. The mounting plate portion 316d is provided in the room and extends in the depth direction from the edge on the indoor side and inner circumference of the resin frame body 316a. The opposing projection portion 316e protrudes outward from the visible surface of the resin frame body 316a facing the outside. As is clear from the figure, the opposing projection portion 316e is provided in a part that is slightly on the outer circumference side than the inner circumference edge of the resin frame body 316a.

[0034] In the vertical frame 33 having the above configuration, the bent portion of the outer insertion fin portion 316b is inserted into the intermediate upper resin frame insertion portion 315e, the inner insertion fin portion 316c is inserted into the inner upper resin frame insertion portion 315c, and the inner upper resin frame insertion portion 315c is crimped, thereby mounting the resin frame portion 316 to the metal frame portion 315. When crimping the inner upper resin frame insertion portion 315c, this can be easily done by inserting crimping press devices from both ends of the metal frame portion 315.

[0035] The resin frame portion 316, which is attached to the metal frame portion 315, has its inner circumference-facing surface of the resin frame body 316a positioned along the depth direction. The projection dimension of the resin frame body 316a toward the inner circumference is set to be approximately the same as that of the inner accommodating groove forming piece 315d. Between the upper outer panel support portion 315b and the inner accommodating groove forming piece 315d provided on the metal frame portion 315, the side edges of the panel 40 are supported via sealing material S2, with the retaining edge 34 attached to the inner accommodating groove forming piece 315d. The retaining edge 34 is composed of a metal retaining edge portion 317 and a resin retaining edge portion 318.

[0036] The metal trim piece 317 is an extruded profile formed from a metal such as an aluminum alloy, and is composed of a groove-forming piece 317a, an inner circumference engaging piece 317b, and an outer circumference engaging piece 317c. The groove-forming piece 317a extends along the visible direction. The groove-forming piece 317a has a resin mounting portion 317d on the visible surface facing the interior. The resin mounting portion 317d is for mounting the resin trim piece 318 and has a double-ridged convex shape. The inner circumference engaging portion 317b extends outward from the outer edge of the groove-forming piece 317a, then curves outward, forming an engaging groove portion 317e that opens to the interior. The outer circumference engaging piece 317c extends inclined from the outer edge of the inner circumference engaging portion 317b outward, gradually becoming more outer-circumferential, then bends and extends outward in the depth direction.

[0037] The resin trim portion 318 is an extruded profile molded from resin and consists of a trim base portion 318a, a metal mounting portion 318b, and a resin frame opposing piece portion 318c. The trim base portion 318a has a rectangular hollow cross-section. The metal mounting portion 318b has two recesses into which the resin mounting portion 317d described above can be inserted. By inserting the resin mounting portion 317d into the metal mounting portion 318b, the resin trim portion 318 can be attached to the portion of the housing groove forming piece 317a facing the interior. The resin frame opposing piece portion 318c extends from the outer edge of the trim base portion 318a, which is also on the interior side, outwards. The extended edge of the resin frame opposing piece portion 318c is bent outwards first, and then bent outwards.

[0038] The aforementioned trim piece 34 is attached to the metal trim piece 317 via the resin mounting portion 317d and the metal mounting portion 318b, and from this state, the outdoor-side edge of the outer peripheral engaging piece 317c is engaged between the trim engaging portion 315h and the inner peripheral visible wall portion 315g, and the engaging groove portion 317e of the inner peripheral engaging portion 317b is engaged with the inner housing groove forming piece 315d of the metal frame portion 315, thereby attaching it to the metal frame portion 315 via the metal trim piece 317. The resin trim piece 318 is positioned between the housing groove forming piece 317a and the resin frame portion 316, with the extended edge of the resin frame opposing piece portion 318c engaging with the opposing projection portion 316e.

[0039] <Example 3> Figures 7 to 10 show three embodiments of a joinery constructed using frame profiles, which are embodiments of the present invention. The joinery illustrated here is called a stepped window, having an upper vertical sliding window and a lower fixed window inside a single frame 50.

[0040] The frame 50 is composed of an upper frame 51, a transom (internal frame profile) 52, a lower frame 53, and left and right vertical frames (frame profiles) 54. Specifically, the frame 50 has a sash (panel material) 20 that constitutes a vertical sliding window, which is arranged in the area enclosed by the upper frame 51, transom 52, and left and right vertical frames 54 so that it can be opened to the outside, and a panel (panel material) 40 such as double-glazed glass that constitutes a fixed window is arranged in the area enclosed by the transom 52, lower frame 53, and left and right vertical frames 54. The upper frame 51, transom 52, lower frame 53, and left and right vertical frames 54 that constitute the frame 50 are each composed of a metal frame part formed from a metal such as an aluminum alloy and a resin frame part formed from resin. The sash 20 is the same as the one applied to the vertical sliding window shown in Example 1, and the panel 40 is the same as the one applied to the fixed window shown in Example 2. Furthermore, since the vertical frames 54 are constructed to be symmetrical, the same reference numerals will be used to describe them on both the left and right sides.

[0041] (Composition of the upper frame 51) The metal frame portion 511 and resin frame portion 512 of the upper frame 51 have the same configuration as the metal frame portion 211 and resin frame portion 212 applied to the upper frame 11 of the single-window vertical sliding window shown in Example 1. That is, the metal frame portion 511 is integrally molded with the upper metal frame body 211a, upper door stop wall portion 211b, upper resin frame insertion portion 211c, upper cover groove portion 211e, and upper insertion groove 211f. The resin frame portion 512 is integrally molded with the upper resin frame body 212a, upper frame cover portion 212b, upper insertion fin portion 212c, upper mounting plate portion 212d, and upper cover projection portion 212e. It is attached to the metal frame portion 211 by inserting the upper cover projection portion 212e into the upper cover groove portion 211e and the upper insertion fin portion 212c into the upper insertion groove 211f.

[0042] (A composition of 52 no-marked characters) The metal frame portion 521 of the transom 52 is integrally molded from a metal body 521a, a door stop wall portion 521b, an upper resin frame insertion portion 521c, an outer panel support portion 521d, an inner panel support portion 521e, and a lower resin frame insertion portion 521f. The metal body 521a has an irregular shape, with the exterior-facing surface and the interior-facing surface extending almost vertically. The door stop wall portion 521b extends upward in the exterior direction from the portion of the upper surface of the metal body 521a that is closer to the interior side. A sealing member S1 is attached to the portion of the upper edge of the door stop wall portion 521b that faces the exterior. An upper cover groove portion 521g that opens upward is provided on the portion of the upper edge of the door stop wall portion 521b that faces the interior. The upper resin frame insertion portion 521c is provided on the upper surface of the metal body 521a, on the edge facing the interior, and opens upward. The outer panel support portion 521d extends downward in the visible direction from the edge facing the exterior on the lower surface of the metal body 521a. The inner panel support portion 521e extends downward in the visible direction from a position on the lower surface of the metal body 521a that is on the interior side than the outer panel support portion 521d. These outer panel support portions 521d and inner panel support portions 521e are provided facing each other with a gap between them that is larger than the thickness of the panel 40. The outer pocket portion 521i is provided on the extended edge of the outer panel support portion 521d so as to protrude from the portion facing the interior. The extended edge of the inner panel support portion 521e is provided with an inner pocket portion 521j in the part facing the outside, and further down, an upper cover groove portion 521k that opens outwards is provided. The lower resin frame insertion portion 521f is a groove-shaped part provided on the inner edge of the lower surface of the metal body 521a, and is formed to open downwards.

[0043] The resin frame portion 522 of the transom 52 is composed of three parts: an upper resin frame portion 523 provided on the indoor side of the upper part of the metal frame portion 521, a lower resin frame portion 524 provided on the indoor side of the lower part of the metal frame portion 521, and a cover resin frame portion 525 provided between the upper resin frame portion 523 and the lower resin frame portion 524.

[0044] The upper resin frame section 523 is formed by integrally molding the upper resin frame body 523a and the upper insertion fin section 523b. The upper resin frame body 523a extends almost horizontally along the depth direction and is formed to protrude into the room from the door stop wall section 521b beyond the upper resin frame insertion section 521c on the upper surface of the metal frame section 521. On the lower surface of the upper resin frame body 523a, on the side facing the outside, there is an upper cover projection 523c that extends downward in the depth direction. The upper insertion fin section 523b extends downward in the visibility direction from a point approximately midway along the depth direction on the lower surface of the upper resin frame body 523a. This upper resin frame section 523 is attached to the metal frame section 521 by inserting the upper cover projection 523c into the upper cover groove section 521g and inserting the upper insertion fin section 523b into the upper resin frame insertion section 521c. As is clear from the diagram, in the metal frame portion 521 to which the upper resin frame portion 523 is attached, the upper edge surface of the door stop wall portion 521b and the upper surface of the portion located further inside the room are covered by the upper resin frame portion 523.

[0045] The lower resin frame section 524 has a lower resin frame body 524a, an outer cover piece 524b, an inner insertion fin section 524c, and a mounting plate section 524d. The lower resin frame body 524a has a hollow shape with a roughly rectangular cross-section. The outer cover piece 524b extends outward in the depth direction from the lower edge on the outdoor side of the lower resin frame body 524a, then bends upward, and then bends further inward. The inner insertion fin section 524c is inserted into the lower resin frame insertion section 521f of the metal frame section 521 and extends upward from the upper edge on the indoor side of the lower resin frame body 524a. The mounting plate section 524d extends inward in the depth direction from the upper part on the indoor side of the lower resin frame body 524a. The lower resin frame portion 524 is attached to the metal frame portion 521 by locking the bent portion of the outer cover piece portion 524b into the upper cover groove portion 521k and inserting the inner insertion fin portion 524c into the lower resin frame insertion portion 521f, thereby covering the lower edge of the inner panel support portion 521e and the lower surface of the portion that is on the interior side of the inner panel support portion 521e.

[0046] The cover resin frame portion 525 has a hollow, flat cover base portion 525a that has height to be inserted between the upper resin frame body 523a of the upper resin frame portion 523 and the mounting plate portion 524d of the lower resin frame portion 524, and hollow joint portions 525b that extend outward from both the upper and lower edges of the cover base portion 525a. This cover resin frame portion 525 is attached between the upper resin frame body 523a and the mounting plate portion 524d by screwing a screw member N1 into the joint portion 525b via the upper resin frame body 523a and the mounting plate portion 524d, and covers the visible surface of the metal frame portion 521 that faces the interior of the room.

[0047] As described above, the transom 52 is configured such that the upper edge of the panel 40 is supported between the outer panel support portion 521d and the inner panel support portion 521e, respectively, via a sealing material S2.

[0048] (Composition of the lower frame 53) The metal frame portion 531 and resin frame portion 532 of the lower frame 53 have the same configuration as the metal frame portion 313 and resin frame portion 314 applied to the lower frame 32 of the single-window FIX window shown in Example 2. Specifically, the metal frame portion 531 is integrally molded with a metal frame body 313a, a lower outer panel support portion 313b, a lower inner panel support portion 313c, a lower resin frame insertion portion 313d, an outer pocket portion 313e, an inner pocket portion 313f, and a lower cover groove portion 313g. The resin frame portion 532 is integrally molded with a resin frame body 314a, an outer cover piece portion 314b, an inner cover piece portion 314c, and a lower inner insertion fin portion 314d.

[0049] As described above, the lower frame 53 is configured such that the lower edge of the panel 40 is supported between the lower outer panel support portion 313b and the lower inner panel support portion 313c, respectively, via a sealing material S2.

[0050] (Composed of 54 vertical frames) As shown in Figures 9 to 12, the metal frame portions (first metal forming portions) 540 of the left and right vertical frames 54 include a reference forming portion 541 arranged in a continuous line from the upper frame 51 through the transom 52 to the lower frame 53, an upper attachment forming portion (attachment forming portion) 542 mounted above the transom 52 in the reference forming portion 541, and a lower attachment forming portion (attachment forming portion) 543 mounted below the transom 52 in the reference forming portion 541.

[0051] The base molded portion 541 of the metal frame portion 540 is configured to include a portion common to both the metal frame portion 215 of the vertical frame 13 applied to the vertical sliding window of Example 1 and the metal frame portion 315 of the vertical frame 33 applied to the fixed window of Example 2. The upper attachment molded portion 542 is configured so that when attached to the base molded portion 541, the outer shape of the portion that supports the sash 20 on the inner circumference above the transom 52 has a portion that is identical to the metal frame portion 215 of the vertical frame 13 applied to the vertical sliding window of Example 1. In other words, when the upper attachment molded portion 542 is attached to the base molded portion 541, the sash 20 can be opened and closed and supported in the portion enclosed by the upper frame 51, the transom 52, and the left and right vertical frames 54. Similarly, the lower attachment molding section 543 is configured such that, when attached to the base molding section 541, the outer shape of the portion supporting the panel 40 on the inner circumference below the transom 52 is the same as that of the metal frame portion 315 of the vertical frame 33 applied to the FIX window of Embodiment 2. In other words, when the lower attachment molding section 543 is attached to the base molding section 541, the panel 40 can be supported via the trim 34 in the portion enclosed by the transom 52, the lower frame 53, and the left and right vertical frames 54.

[0052] (Configuration of the standard molded section 541) The standard molded section 541 is integrally molded with a metal frame body 541a, an outer visible wall section 541b, and an inner visible wall section 541c. The metal frame body 541a is a flat plate shape that extends almost vertically along the depth direction. The dimensions of the metal frame body 541a along the depth direction are the same as those of the metal frame body 215a of the metal frame section 215 that constitutes the vertical frame 13 of the vertical sliding window shown in Example 1. The outer visible wall section 541b is a flat plate shape that extends along the depth direction at the edge located on the exterior side of the metal frame body 541a. The inner visible wall section 541c is a flat plate shape that extends along the depth direction at the edge located on the interior side of the metal frame body 541a. A resin frame insertion section (first insertion section) 541d that opens toward the inner circumference is provided in the portion located on the inner circumference side of the inner visible wall section 541c. The position in which the resin frame insertion portion 541d is provided relative to the metal frame body 541a is the same as the position in which the resin frame insertion portion 215e is provided relative to the metal frame body 215a in the metal frame portion 215 of Embodiment 1.

[0053] (Configuration of the upper attachment molding section 542) As shown in Figure 11, the upper attachment molding section 542 is made by integrally molding the upper metal attachment body 542a, the upper metal outer support wall section 542b, the upper metal inner support wall section 542c, the upper metal door stop component wall section 542d, and the upper cover insertion section 542e.

[0054] The upper metal attachment body 542a is a flat plate that extends vertically along the depth direction. The length of the upper metal attachment body 542a along the depth direction is the same as the inner circumferential wall portion 215g provided on the metal frame portion 215 of Example 1. The upper metal outer support wall portion 542b extends from the edge located on the outdoor side of the upper metal attachment body 542a toward the outer circumference in the visibility direction. The dimensions of the upper metal outer support wall portion 542b along the visibility direction are the same as the outer circumferential wall portion 215b provided on the metal frame portion 215 of Example 1. The upper metal inner support wall portion 542c extends from the edge located on the indoor side of the upper metal attachment body 542a toward the outer circumference in the visibility direction, and then bends toward the outdoor side. The dimensions of the upper metal inner support wall portion 542c along the visibility direction are the same as the upper metal outer support wall portion 542b. A sealing member S3 is attached to the outer edge of the upper metal inner support wall portion 542c. The upper metal door stop component wall portion 542d extends in the visible direction from the edge located on the indoor side of the upper metal attachment body 542a toward the inner circumference. A sealing member S1 is attached to the portion of the inner circumference edge of the upper metal door stop component wall portion 542d that faces the outside. The sealing member S1 is in series with the sealing member S1 attached to the upper door stop wall portion 211b of the upper frame 51 and the door stop wall portion 521b of the transom 52.

[0055] A lower cover groove 542f is provided on the inner edge of the upper metal door stopper wall portion 542d that faces the interior of the room. The lower cover groove 542f is configured such that when the exterior-facing surface of the upper metal outer support wall portion 542b is brought into contact with the interior-facing surface of the outer facing wall portion 541b, and the outer edge of the upper metal outer support wall portion 542b and the outer edge of the upper metal inner support wall portion 542c are brought into contact with the inner-facing surface of the metal frame body 541a, the position of the lower cover groove 542f relative to the resin frame insertion portion 541d is the same as the position of the lower cover groove 215f relative to the resin frame insertion portion 215e in the metal frame portion 215 of Embodiment 1. The upper cover insertion portion 542e is provided on the visible surface of the upper metal door stop component wall portion 542d located on the indoor side, in a portion corresponding to the connection portion with the upper metal attachment body 542a, and is open toward the inner circumference. The upper cover insertion portion 542e is provided in a position where the bent portion of the outer insertion fin portion 216d can be inserted when the visible surface of the upper metal outer support wall portion 542b facing the outdoors is brought into contact with the visible surface of the outer visible wall portion 541b facing the indoor side, and the edge located on the outer circumference side of the upper metal outer support wall portion 542b and the edge located on the outer circumference side of the upper metal inner support wall portion 542c are brought into contact with the visible surface which is the inner circumference side of the metal frame body 541a, and when the inner insertion fin portion 216c of the resin frame portion 216 of Embodiment 1 is inserted into the resin frame insertion portion 541d and the cover projection portion 216f is inserted into the lower cover groove portion 542f.

[0056] The upper attachment molding section 542 described above is connected to the base molding section 541 by screwing a screw N3 into the bent portion of the upper metal inner support wall section 542c via the metal frame body 541a, with the exterior-facing surface of the upper metal outer support wall section 542b in contact with the interior-facing surface of the outer visible wall section 541b.

[0057] In the vertical frame 54, the same resin frame portion 216 as that applied to the vertical frame 13 of the vertical sliding window shown in Embodiment 1 is attached to the upper attachment molding portion 542. That is, the upper attachment molding portion 542 can be fitted with a resin frame portion 216 in which the resin frame body 216a, frame cover portion 216b, inward insertion fin portion 216c, outward insertion fin portion 216d, mounting plate portion 216e, and cover projection portion 216f are integrally molded.

[0058] (Configuration of the lower attachment molding section 543) As shown in Figure 12, the lower attachment molding section 543 is integrally molded with a metal attachment body 543a, an outer support wall section 543b, an outer panel support section 543c, an inner support wall section 543d, a housing groove forming section 543e, and a resin frame insertion section 543f. The metal attachment body 543a is a flat plate shape that extends vertically along the depth direction. The length of the metal attachment body 543a along the depth direction is the same as the inner circumference facing wall section 315g provided on the metal frame section 315 of Example 2. A trim engagement section 543g is provided on the inner circumference facing surface of the metal attachment body 543a. The trim engagement section 543g protrudes inward from the metal attachment body 543a and then bends inward, ensuring a gap between it and the metal attachment body 543a. The dimension from the edge of the metal attachment body 543a located on the indoor side to the trim engagement portion 543g is the same as the dimension from the edge of the inner perimeter visible wall portion 315g located on the indoor side to the trim engagement portion 315h. The outer support wall portion 543b extends in the visible direction toward the outer perimeter from the edge of the metal attachment body 543a located on the outdoor side. The dimension of the outer support wall portion 543b along the visible direction is the same as the dimension of the outer visible wall portion 541b of the reference molding portion 541 that protrudes inward from the metal frame body 541a. The outer panel support portion 543c extends in the visible direction toward the inner perimeter from the edge of the metal attachment body 543a located on the outdoor side. The dimensions of the outer panel support portion 543c along the visible direction are the same as the dimensions of the portion that protrudes inward from the inner visible wall portion 315g in the upper outer panel support portion 315b provided on the metal frame portion 315 of Embodiment 2. The extended edge of the outer panel support portion 543c is provided such that the outer pocket portion 543h protrudes from the portion facing the interior of the room. The inner support wall portion 543d extends in the visible direction from the edge located on the interior side of the metal attachment body 543a toward the outer periphery, and then bends toward the interior. The dimensions of the inner support wall portion 543d along the visible direction are set so that, together with the outer support wall portion 543b, when the edges located on the outer periphery of each portion abut against the visible surface on the inner periphery side of the metal frame body 541a, the metal attachment body 543a is parallel to the metal frame body 541a.A sealing member S4 is attached to the outer edge of the inner support wall portion 543d, specifically the portion facing the outdoor side. The accommodating groove forming portion 543e extends in the visible direction from the edge located on the indoor side of the metal attachment body 543a toward the inner circumference, and then bends toward the outdoor side. The position of the accommodating groove forming portion 543e relative to the trim engagement portion 543g is the same as the position of the inner accommodating groove forming piece 315d relative to the trim engagement portion 315h provided on the metal frame portion 315 in Embodiment 2, making it possible to attach the trim 34 applied in Embodiment 2. The resin frame insertion portion 543f is provided on the visible surface located on the indoor side of the inner support wall portion 543d, on the outer circumference side of the metal attachment body 543a, and opens toward the inner circumference. The resin frame insertion portion 543f is positioned so that when the inner insertion fin portion 316c of the resin frame portion 316 of Embodiment 2 is inserted into the resin frame insertion portion 541d of the reference molding portion 541, the bent portion of the outer insertion fin portion 316b can be inserted, with the outer-facing surface of the outer support wall portion 543b facing the outside in contact with the inner-facing surface of the outer visible wall portion 541b, and the outer edge of the outer support wall portion 543b and the outer edge of the inner support wall portion 543d both in contact with the inner surface of the metal frame body 541a.

[0059] The aforementioned lower attachment molding section 543 is connected to the base molding section 541 by screwing a screw N4 into the bent portion of the inner support wall section 543d via the metal frame body 541a, with the outer surface of the outer support wall section 543b facing the outside in contact with the inner surface of the outer visible wall section 541b facing the inside.

[0060] In the vertical frame 54, the same resin frame portion 316 as that applied to the vertical frame 33 of the FIX window shown in Example 2 is attached to the lower attachment molding portion 543. That is, it is possible to attach a resin frame portion 316, which is integrally molded with a resin frame body 316a, an outer insertion fin portion 316b, an inner insertion fin portion 316c, a mounting plate portion 316d, and an opposing protruding portion 316e, to the lower attachment molding portion 543.

[0061] (Construction of the multi-tiered window) When the frame body 50 is constructed using the upper frame 51, transom 52, lower frame 53, and left and right vertical frames 54 configured as described above, the transom 52 is connected to the reference molding section 541 with the upper resin frame section 523 and lower resin frame section 524 already attached to the metal frame section 521 of the transom 52, as shown in Figure 13(a). When attaching the upper resin frame section 523 to the metal frame section 521, the upper insertion fin section 523b is inserted into the upper resin frame insertion section 521c, and then the upper resin frame insertion section 521c is crimped to connect it to the metal frame section 521. At this time, since both ends of the upper resin frame section 523 are positioned close to both ends of the metal frame section 521, it is possible to easily crimp them by inserting a crimping press device from both ends of the metal frame section 521. Similarly, when attaching the lower resin frame portion 524 to the metal frame portion 521, the inner insertion fin portion 524c is inserted into the lower resin frame insertion portion 521f, and then the lower resin frame insertion portion 521f is crimped to connect it to the metal frame portion 521. At this time, since both ends of the lower resin frame portion 524 are positioned close to both ends of the metal frame portion 521, it is possible to easily crimp them by inserting a crimping press device from each end of the metal frame portion 521.

[0062] Next, as shown in Figure 13(b), the upper attachment molding section 542 is connected to the reference molding section 541 at a position above the transom 52 with the resin frame section 216 already attached, and the lower attachment molding section 543 is connected to the reference molding section 541 at a position below the transom 52 with the resin frame section 316 already attached. When attaching the resin frame section 216 to the upper attachment molding section 542, the cover projection 216f is inserted into the lower cover groove 542f, the inner insertion fin section 216c is inserted into the resin frame insertion section 541d, and the outer insertion fin section 216d is inserted into the upper cover insertion section 542e. After that, the upper attachment molding section 542 can be connected by crimping the upper cover insertion section 542e. At this time, since both ends of the resin frame portion 216 are positioned close to both ends of the upper attachment molding portion 542, they can be easily crimped by inserting a crimping press device from each end of the upper attachment molding portion 542. Similarly, when attaching the resin frame portion 316 to the lower attachment molding portion 543, the inner insertion fin portion 316c is inserted into the resin frame insertion portion 541d, and the outer insertion fin portion 316b is inserted into the resin frame insertion portion 543f, and then the resin frame insertion portion 543f is crimped to connect it to the lower attachment molding portion 543. At this time, since both ends of the resin frame portion 316 are positioned close to both ends of the lower attachment molding portion 543, they can be easily crimped by inserting a crimping press device from each end of the lower attachment molding portion 543.

[0063] Finally, as shown in Figure 13(c), the frame body 50 for the stepped window can be constructed by connecting the upper frame 51 between the upper ends of the reference molded parts 541 with the resin frame part 512 already attached to the metal frame part 511, and connecting the lower frame 53 between the lower ends of the reference molded parts 541 with the resin frame part 532 already attached to the metal frame part 531. When attaching the resin frame part 512 to the metal frame part 511, the upper insertion fin part 212c is inserted into the upper insertion groove 211f, and the upper cover projection part 212e is inserted into the upper cover groove part 211e, and then the upper insertion groove 211f is crimped to connect it to the metal frame part 511. At this time, since both ends of the resin frame part 512 are positioned close to both ends of the metal frame part 511, it can be easily crimped by inserting a crimping press device from both ends of the metal frame part 511. Similarly, when attaching the resin frame portion 532 to the metal frame portion 531, the lower inward insertion fin portion 314d is inserted into the lower resin frame insertion portion 313d, and then the lower resin frame insertion portion 313d is crimped to connect it to the metal frame portion 531. At this time, since both ends of the resin frame portion 532 are positioned close to both ends of the metal frame portion 531, it can be easily crimped by inserting a crimping press device from each end of the metal frame portion 531.

[0064] As explained above, the resin frame portion 216 attached to the vertical frame 13 of a single vertical sliding window is provided with two crimping portions, an inward insertion fin portion 216c and an outward insertion fin portion 216d. Therefore, for the vertical frame 13 of a single vertical sliding window, the resin frame portion 216 can be connected to the metal frame portion 215 by inserting the inward insertion fin portion 216c into the resin frame insertion portion 215e and crimping it. On the other hand, in a stepped window equipped with a vertical sliding window, the resin frame portion 216 can be attached to the upper attachment molding portion 542 in advance by inserting the outward insertion fin portion 216d into the upper cover insertion portion 542e and crimping it, and in this state, the upper attachment molding portion 542 can be connected to the base molding portion 541. Therefore, the resin frame portion 216 can be shared between a single vertical sliding window to which the metal frame portion 215 is applied and a stepped window to which the metal frame portion 540, which includes a base molded portion 541 and an upper attachment molded portion 542, is applied.

[0065] Similarly, as described above, a resin frame portion 316 that is attached to the vertical frame 33 of a single fixed window is provided with two crimping portions, an outward insertion fin portion 316b and an inward insertion fin portion 316c. Therefore, for the vertical frame 33 of a single fixed window, the resin frame portion 316 can be connected to the metal frame portion 315 by inserting the inward insertion fin portion 316c into the inner upper resin frame insertion portion 315c and crimping it. On the other hand, in a stepped window equipped with a fixed window, the resin frame portion 316 can be attached to the lower attachment molding portion 543 in advance by inserting the outward insertion fin portion 316b into the resin frame insertion portion 543f and crimping it, and in this state, the lower attachment molding portion 543 can be connected to the reference molding portion 541. Therefore, the resin frame portion 316 can be shared between a single fixed window to which the metal frame portion 315 is applied and a stepped window to which the metal frame portion 540, which includes a base molded portion 541 and a lower attachment molded portion 543, is applied.

[0066] In the above-described embodiment 3, a stepped window equipped with a transom 52 as a central frame profile is illustrated, but it is also possible to apply the same method to a continuous window equipped with a mullion as a central frame profile, as shown in the modified example in Figure 14. That is, in the continuous window shown in Figure 14, the frame is composed of left and right vertical frames 61, 62, a mullion (central frame profile) 63, an upper frame (frame profile) 64, and a lower frame (frame profile) 65. The left and right vertical frames 61, 62 are composed of metal frame parts 604, 605 and resin frame parts 707, 708 which are attached to the inner circumference of the metal frame parts 604, 605, respectively. The mullion 63 is composed of a metal frame part 603 and a left resin frame part 705 and a right resin frame part 706 which are attached to both sides of the metal frame part 603. The upper frame 64 is composed of an upper reference molding section 601 which is a single unit on the left and right sides, an upper left attachment molding section (attachment molding section) 611 which is connected to the left of the mullion 63 on the inner circumference side of the upper reference molding section 601, and an upper right attachment molding section (attachment molding section) 613 which is connected to the right of the mullion 63 on the inner circumference side of the upper reference molding section 601, forming a metal frame section. An upper left resin frame section (resin molding section) 701 is attached to the part of the upper left attachment molding section 611 that is on the inner circumference side, and an upper right resin frame section (resin molding section) 703 is attached to the part of the upper right attachment molding section 613 that is on the inner circumference side. Similarly, the lower frame 65 is composed of a metal frame comprising a lower reference molded section 602 which is a single unit on the left and right sides, a lower left attachment molded section (attachment molded section) 612 which is connected to the left of the mullion 63 on the inner circumference side of the lower reference molded section 602, and a lower right attachment molded section (attachment molded section) 614 which is connected to the right of the mullion 63 on the inner circumference side of the lower reference molded section 602. The lower left attachment molded section 612 has a lower left resin frame section (resin molded section) 702 attached to the inner circumference side portion, and the lower right attachment molded section 614 has a lower right resin frame section (resin molded section) 704 attached to the inner circumference side portion.

[0067] In this window as well, by applying upper left resin frame section 701 and upper right resin frame section (resin molded section) 703, which are attached to the upper frame 64, and each having a crimping section for a multi-window and a crimping section for a single window, it becomes possible to share the resin frame sections 701 and 703 between a multi-window and a single window. Similarly, by applying lower left resin frame section 702 and lower right resin frame section 704, which are attached to the lower frame 65, and each having a crimping section for a multi-window and a crimping section for a single window, it becomes possible to share the resin frame sections 702 and 704 between a multi-window and a single window.

[0068] As described above, the frame profile according to the present invention comprises a resin molded portion formed from resin, and a first metal molded portion and a second metal molded portion having portions where at least the inner circumference facing the surface material has the same outer shape when the resin molded portion is attached, and is formed by attaching the resin molded portion to the first metal molded portion or the second metal molded portion and crimping a crimping portion, wherein the first metal molded portion is formed by connecting a base reference molded portion and an attachment molded portion attached to the reference molded portion, the second metal molded portion is integrally molded with portions corresponding to the reference molded portion and the attachment molded portion, and the resin molded portion has a first crimping portion that is crimped between it and the attachment molded portion and a second crimping portion that is crimped between it and the second metal molded portion, and the first crimping portion and the second crimping portion are provided at different positions from each other. According to this invention, the resin molded portion is provided with a first crimping portion and a second crimping portion. Therefore, the resin molded portion can be pre-crimped to the attachment molded portion via the first crimping portion with respect to the first metal molded portion, and the resin molded portion can also be attached to the reference molded portion with the central frame profile already attached. On the other hand, the resin molded portion can be crimped to the second metal molded portion via the second crimping portion. As a result, the same resin molded portion can be applied to stepped windows and connected windows to which the first metal molded portion is applied, and to single windows to which the second metal molded portion is applied, thereby enabling the sharing of parts.

[0069] Furthermore, the present invention is characterized in that, in the frame profile described above, the first metal forming portion is provided with a first insertion portion into which the second crimping portion is inserted into the reference forming portion. According to this invention, since the second crimping portion is inserted into the first insertion portion, the resin frame portion is also supported by the reference molding portion, and the situation in which the resin frame portion detaches from the first metal molding portion can be more reliably prevented.

[0070] Furthermore, the present invention is characterized in that, in the frame profile described above, the second metal forming portion is provided with a second insertion portion into which the first crimping portion is inserted. According to this invention, since the first crimping portion is inserted into the second insertion portion, the resin frame is supported at two points relative to the second metal molded portion, thereby more reliably preventing the resin frame from falling off the second metal molded portion.

[0071] Furthermore, the present invention is characterized in that, in the frame profile described above, the attachment molding portion is provided in the reference molding portion on the outdoor side of the resin molding portion, and the first crimping portion is provided in the outdoor side of the second crimping portion. According to this invention, the resin molding section is positioned on the interior side of the standard molding section compared to the attachment molding section, which is advantageous in terms of heat insulation.

[0072] Furthermore, the present invention is characterized in that, in the frame profile described above, the first metal formed part has a central rib profile connected in the middle of the reference formed part, and the cross-sectional shapes of the attachment formed part are different on one side and the other side of the central rib profile. According to this invention, it is possible to construct stepped windows and continuous windows with different support configurations for the facing materials.

[0073] Furthermore, the joinery according to the present invention is characterized in that the first metal molded part and the resin molded part are applied as vertical frames of the frame, a central rib profile is connected in the middle of the standard molded part, the cross-sectional shape of the attachment molded part is different on one side and the other side of the central rib profile, and the surface material is arranged above and below the central rib profile in different support configurations. According to this invention, a stepped window can be constructed using a vertical frame equipped with a series of reference molded sections at the top and bottom.

[0074] Furthermore, the joinery according to the present invention is characterized in that the first metal molded part and the resin molded part are applied as horizontal frames of the frame, a central rib profile is connected in the middle of the standard molded part, the cross-sectional shape of the attachment molded part is different on one side and the other side of the central rib profile, and the facing material is arranged on the left and right sides of the central rib profile in different support configurations. According to this invention, a series of windows can be constructed using a horizontal frame equipped with a series of reference molded sections on the left and right sides. [Explanation of Symbols]
