Summary of the Invention

Problems to be Solved by the Invention

[0004] In fittings, by disposing internal frame members such as muntins or vertical bars inside the frame, there are cases where a stepped window or a continuous window in which facing materials are disposed in different support forms inside one frame is configured. For example, in the case of a stepped window, by providing a muntin inside the frame, an opening window can be configured above the muntin, while a FIX window can be configured below the muntin.

[0005] In this type of fitting, a reference molded part having a common cross-sectional shape above and below the muntin 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 muntin in the reference molded part. In such fittings, even when there are many types of support forms of the facing material, it is possible to make a corresponding arrangement using a common reference molded part by changing the attachment molded part to be applied.

[0006] Here, for fittings lined up in the same product series, it is desirable to share parts as much as possible. For this reason, even between a single window having only a facing material on the frame and the above-described stepped window, it is preferable to share the resin molded part among those having the same support form of the facing material.

[0007] However, the attachment molded part and the resin molded part need to be attached to the reference molded part in a state where the joints are connected. For this reason, the resin molded part cannot be caulked to the reference molded part, and the actual situation is that it has not yet been realized. That is, when configuring the frame of a single window, both ends of the resin molded part are arranged close to the opening end surface of the metal molded part. Therefore, after inserting the caulking part of the resin frame part into the insertion part of the metal molded part, it is possible to easily caulk between the metal molded part and the resin molded part by inserting a caulking press device from both ends of the metal molded part. However, when configuring the frame of a stepped window or a continuous window, since one end of the resin molded part is arranged at a position close to a middle frame member such as a joint or a vertical post, a caulking press device cannot be arranged for one end of this resin molded part, and it becomes difficult to caulk between the reference molded part and the resin molded part.

[0008] In view of the above situation, an object of the present invention is to provide a frame profile and a fitting in which a resin molded part applicable to a single window can also be applied to a stepped window or a continuous window.

Means for Solving the Problems

[0009] In order to achieve the above object, the profile for a frame according to the present invention includes a resin molded part molded by resin, and a first metal molded part and a second metal molded part having a portion where the inner peripheral sides facing at least the facing material are the same outer shape when the resin molded part is attached. The profile for a frame is configured by attaching the resin molded part to the first metal molded part or the second metal molded part and caulking a caulked part. The first metal molded part is configured by connecting a reference molded part serving as a base and an attachment molded part attached to the reference molded part to each other. The second metal molded part is formed by integrally molding portions corresponding to the reference molded part and the attachment molded part. The resin molded part has a first caulked part caulked between the resin molded part and the attachment molded part, and a second caulked part caulked between the resin molded part and the second metal molded part. The first caulked part and the second caulked part are provided at different positions from each other.

[0010] In addition, the fitting according to the present invention is such that the first metal molded part and the resin molded part are applied as a vertical frame of a frame body, a middle frame member is connected in the middle of the reference molded part, the cross-sectional shapes of the attachment molded parts are different from each other on one side and the other side of the middle frame member, and the facing materials are arranged in different support forms above and below the middle frame member.

[0011] In addition, the fitting according to the present invention is such that the first metal molded part and the resin molded part are applied as a horizontal frame of a frame body, a middle frame member is connected in the middle of the reference molded part, the cross-sectional shapes of the attachment molded parts are different from each other on one side and the other side of the middle frame member, and the facing materials are arranged in different support forms on the left and right of the middle frame member.

Advantages of the Invention

[0012] According to the present invention, a first caulking portion and a second caulking portion are provided in the resin molding portion. Therefore, with respect to the first metal molding portion, the resin molding portion can be caulked to the attachment molding portion through the first caulking portion in advance, and the resin molding portion can also be attached to the reference molding portion with the middle frame member attached. On the other hand, with respect to the second metal molding portion, the resin molding portion can be caulked through the second caulking portion. As a result, the same resin molding portion can be applied to the stepped window or continuous window to which the first metal molding portion is applied and the single window to which the second metal molding portion is applied, and the sharing of parts can be achieved.

The housing groove forming piece 317a extends along the finding direction. The housing groove forming piece 317a is provided with a resin mounting portion 317d on the finding surface facing the interior of the room. The resin mounting portion 317d mounts the resin pressing edge portion 318 and forms two convex shapes. The inner peripheral engaging portion 317b extends from the edge portion on the outer peripheral side of the housing groove forming piece 317a toward the outside of the room and then curves toward the outer peripheral side, forming an engaging groove portion 317e that opens to the inner side of the room. The outer peripheral engaging piece 317c extends obliquely from the edge portion on the outer peripheral side of the inner peripheral engaging portion 317b toward the outside of the room so as to gradually become the outer peripheral side, then bends, and extends in the prospective direction toward the outside of the room.

[0037] The resin pressing edge portion 318 is an extruded profile formed of resin, and is configured to have a pressing edge base portion 318a, a metal mounting portion 318b, and a resin frame facing piece portion 318c. The pressing edge base portion 318a has a hollow shape with a rectangular cross section. The metal mounting portion 318b forms two concave portions into which the above-described resin mounting portion 317d can be inserted. By inserting the resin mounting portion 317d into the metal mounting portion 318b, it is possible to mount the resin pressing edge portion 318 on the portion of the housing groove forming piece 317a facing the interior of the room. The resin frame facing piece portion 318c extends from the outer peripheral side and the inner side edge portion of the pressing edge base portion 318a toward the outer peripheral side. The extending edge portion of the resin frame facing piece portion 318c bends toward the outside of the room and then bends toward the outer peripheral side.

[0038] The above-mentioned pressing edge 34 attaches the resin pressing edge portion 318 to the metal pressing edge portion 317 via the resin mounting portion 317d and the metal mounting portion 318b. From this state, the outdoor side edge portion of the outer peripheral engaging piece 317c is engaged between the pressing edge engaging portion 315h and the inner peripheral finding wall portion 315g, and the engaging groove portion 317e of the inner peripheral engaging portion 317b is engaged with the inward accommodation groove forming piece 315d of the metal frame portion 315, thereby mounting it on the metal frame portion 315 via the metal pressing edge portion 317. The resin pressing edge portion 318 is in a state where the extending edge portion of the resin frame facing piece portion 318c is engaged with the opposing protruding portion 316e and is disposed between the accommodation groove forming piece 317a and the resin frame portion 316.

At this time, since both ends of the upper resin frame portion 523 are arranged at positions close to both ends of the metal frame portion 521, it is possible to easily caulk by inserting caulking press devices from both ends of the metal frame portion 521, respectively. Similarly, when mounting the lower resin frame portion 524 on the metal frame portion 521, after inserting the inward insertion fin portion 524c into the lower resin frame insertion portion 521f, the lower resin frame insertion portion 521f can be caulked to connect it to the metal frame portion 521. At this time, since both ends of the lower resin frame portion 524 are arranged at positions close to both ends of the metal frame portion 521, it is possible to easily caulk by inserting caulking press devices from both ends of the metal frame portion 521, respectively.

[0062] Next, as shown in FIG. 13(b), with the resin frame portion 216 pre-mounted, the upper attachment molding portion 542 is connected to the reference molding portion 541 at a position above the blind portion 52, and with the resin frame portion 316 pre-mounted, the lower attachment molding portion 543 is connected to the reference molding portion 541 at a position below the blind portion 52. When attaching the resin frame portion 216 to the upper attachment molding portion 542, the cover protrusion 216f is inserted into the lower cover groove portion 542f, the inward insertion fin portion 216c is inserted into the resin frame insertion portion 541d, and further the outward insertion fin portion 216d is inserted into the upper cover insertion portion 542e. Then, by caulking the upper cover insertion portion 542e, it can be connected to the upper attachment molding portion 542. At this time, since both ends of the resin frame portion 216 are arranged at positions close to both ends of the upper attachment molding portion 542, it can be easily caulked by inserting a caulking press device from both ends of the upper attachment molding portion 542, respectively. Similarly, when attaching the resin frame portion 316 to the lower attachment molding portion 543, the inward insertion fin portion 316c is inserted into the resin frame insertion portion 541d, and after the outward insertion fin portion 316b is inserted into the resin frame insertion portion 543f, it can be connected to the lower attachment molding portion 543 by caulking the resin frame insertion portion 543f. At this time, since both ends of the resin frame portion 316 are arranged at positions close to both ends of the lower attachment molding portion 543, it can be easily caulked by inserting a caulking press device from both ends of the lower attachment molding portion 543, respectively.

[0063] Finally, as shown in Fig. 13(c), with the resin frame part 512 pre-mounted on the metal frame part 511, the upper frame 51 is connected between the upper ends of the reference forming part 541, and with the resin frame part 532 pre-mounted on the metal frame part 531, the lower frame 53 is connected between the lower ends of the reference forming part 541, then the frame body 50 for the stepped window can be constituted. When mounting the resin frame part 512 on the metal frame part 511, the upper insertion fin part 212c is inserted into the upper insertion groove 211f, and after the upper cover protrusion 212e is inserted into the upper cover groove part 211e, the upper insertion groove 211f is caulked to connect it to the metal frame part 511. At this time, since both ends of the resin frame part 512 are arranged at positions close to both ends of the metal frame part 511, it can be easily caulked by inserting a caulking press device from both ends of the metal frame part 511 respectively. Similarly, when mounting the resin frame part 532 on the metal frame part 531, after the lower inner insertion fin part 314d is inserted into the lower resin frame insertion part 313d, the lower resin frame insertion part 313d is caulked to connect it to the metal frame part 531. At this time, since both ends of the resin frame part 532 are arranged at positions close to both ends of the metal frame part 531, it can be easily caulked by inserting a caulking press device from both ends of the metal frame part 531 respectively.

[0064] As described above, the resin frame portion 216 attached to the vertical frame 13 of the single-window vertical sliding window is applied with two caulking portions, namely, the inner insertion fin portion 216c and the outer insertion fin portion 216d. Therefore, for the vertical frame 13 of the single-window vertical sliding window, the resin frame portion 216 can be connected to the metal frame portion 215 by inserting the inner insertion fin portion 216c into the resin frame insertion portion 215e and caulking. On the other hand, in the case of a stepped window provided with a vertical sliding window, the resin frame portion 216 can be attached to the upper attachment molding portion 542 by inserting the outer insertion fin portion 216d into the upper cover insertion portion 542e and caulking in advance, and in this state, the upper attachment molding portion 542 can be connected to the reference molding portion 541. Therefore, it is possible to share the resin frame portion 216 between the single-window vertical sliding window applying the metal frame portion 215 and the stepped window applying the metal frame portion 540 including the reference molding portion 541 and the upper attachment molding portion 542.

[0065] Similarly, as described above, the resin frame portion 316 attached to the vertical frame 33 of the single-window FIX window is applied with two caulking portions, namely, the outer insertion fin portion 316b and the inner insertion fin portion 316c. Therefore, for the vertical frame 33 of the single-window FIX window, the resin frame portion 316 can be connected to the metal frame portion 315 by inserting the inner insertion fin portion 316c into the inner upper resin frame insertion portion 315c and caulking. On the other hand, in the case of a stepped window provided with a FIX window, the resin frame portion 316 can be attached to the lower attachment molding portion 543 by inserting the outer insertion fin portion 316b into the resin frame insertion portion 543f and caulking in advance, and in this state, the lower attachment molding portion 543 can be connected to the reference molding portion 541. Therefore, it is possible to share the resin frame portion 316 between the single-window FIX window applying the metal frame portion 315 and the stepped window applying the metal frame portion 540 including the reference molding portion 541 and the lower attachment molding portion 543.

[0066] In addition, in the above-described Example 3, a stepped window provided with a blind 52 as a middle frame member is illustrated, but it can be similarly applied to a continuous window provided with a mullion as a middle frame member as in the modification shown in FIG. 14.
