[0021] The attachment auxiliary member 214 is attached to the upper frame body 211 by inserting the engaging portion 214b into the engaging groove 211h from the end of the upper frame body 211 and sliding it prior to the framing of the new upper frame 21. As shown in Fig. 3(a), the attachment auxiliary member 214 attached to the upper frame body 211 has the engaging portion 214b engaged with the engaging groove 211h of the upper frame body 211, and the bottom wall of the insertion groove 214a is arranged along the attachment protrusion 211g, and if necessary, the bottom wall of the insertion groove 214a is fixed to the attachment protrusion 211g by fixing means b such as screws.

[0022] As shown in Fig. 3(b), the upper molding 71 has an expected wall portion 71a arranged on the indoor side of the new upper frame 21, an angle portion 71b that abuts against the opening of the building, a finding wall portion 71c that connects the expected wall portion 71a and the angle portion 71b, and an insertion portion 71d that extends in the outer peripheral direction from the outer peripheral side surface of the expected wall portion 71a.

[0023] The upper molding 71 can be attached between the building opening and the new upper frame 21 while absorbing deformation of the existing upper frame 11 and the building opening by inserting the insertion portion 71d into the insertion groove 214a of the attachment auxiliary member 214 from the inner peripheral side and abutting the angle portion 71b against the inner peripheral surface of the building opening and fixing it by fixing means such as screws.

[0024] (Configuration of the lower frame part) The lower attachment auxiliary member 32 fixed to the existing lower frame 12 is made of a metal material such as an aluminum alloy and has a new frame placement member 321 and a load support member 322. The new frame placement member 321 has a placement portion 321a that supports the load of the new lower frame 22 and an attachment wall 321b that is continuous with the indoor side of the placement portion 321a, and the attachment wall 321b is fixed to the indoor side wall surface of the existing lower frame 12 by fixing means such as screws.

[0025] The load support member 322 has a support leg 322b fixed to the indoor-side lower rail of the existing lower frame 12, and a support portion 322a provided above the support leg 322b. The placement portion 321a of the newly installed frame placement member 321 is supported on the upper surface of the support portion 322a via a spacer or the like.

[0026] The newly installed lower frame 22 has a lower frame body 221 made of a metal material, and an indoor-side resin lower frame 222 and an outdoor-side resin lower frame 223 disposed on the inner periphery of the lower frame body 221. The lower frame body 221 has an expected wall 221a forming the inner peripheral surface of the newly installed frame, a hollow portion 221c formed on the outer periphery of the expected wall 221a on the outdoor side, a lower inner rail 221d extending in the inner peripheral direction from the inner peripheral surface on the indoor side of the expected wall 221a, and a lower outer rail 221e extending in the inner peripheral direction from the inner peripheral surface on the outdoor side of the expected wall 221a. A frame member attachment portion 221b for attaching the lower frame edge member 72 is provided at the indoor-side end of the expected wall 221a.

[0027] The lower frame body 221 of the newly installed lower frame 22 has a plurality of legs on the outer peripheral side of the expected wall 221a. The plurality of legs are placed on the placement portion 321a of the lower attachment auxiliary member 32 and attached to the lower attachment auxiliary member 32 by fixing means such as screws. In a state where the lower frame body 221 is attached to the existing lower frame 12, the lower end portion on the outdoor side of the hollow portion 221c of the lower frame body 221 faces the anti-lifting member 323 fixed to the existing lower frame 12.

[0028] In order to improve the heat insulation performance, the fitting of the lower frame edge member 72 to the frame member attachment portion 221b is devised in the fitting of the lower frame edge member 72 made of resin to the indoor side of the newly installed lower frame 22 in this embodiment. Hereinafter, the attachment structure of the lower frame edge member 72 will be further described.

[0029] In the newly installed lower frame 22 of this embodiment, an attachment auxiliary member 224 made of resin is attached to the frame member attachment portion 221b, and the resin lower frame edge member 72 is attached via the attachment auxiliary member 224.

[0030] As shown in FIG. 4(b), the frame member mounting portion 221b of the newly installed lower frame 22 is formed at the indoor-side end of the expected wall 221a of the newly installed lower frame 22, and has an indoor-side finding wall 221f continuous with the expected wall 221a, and a mounting protrusion 221g extending in the indoor direction from an intermediate position in the vertical direction on the indoor side of the indoor-side finding wall 221f. An engaging claw 221h is provided at the upper end of the indoor-side finding wall 221f.

[0031] The mounting auxiliary member 224 is a long member having a length dimension similar to the finding dimension of the newly installed lower frame 22, having a hollow portion 224a, and having a frame member engaging groove 224b that is continuous with the indoor side of the hollow portion 224a and opens in the inner circumferential direction. The mounting auxiliary member 224 is provided with an engaging portion 224c on the outdoor side of the hollow portion 224a.

[0032] As shown in FIG. 4(a), the mounting auxiliary member 224 has the hollow portion 224a placed on the mounting protrusion 221g, and the engaging portion 224c is engaged with the engaging claw 221h of the lower frame body 221, and thus the mounting auxiliary member 224 is attached to the lower frame body 221. For the mounting auxiliary member 224 attached to the lower frame body 221, the bottom wall of the frame member engaging groove 224b is placed on a spacer 225 disposed on the frame of the building opening, and the bottom wall of the frame member engaging groove 224b is fixed to the building opening together with the spacer 225 by fixing means b such as screws.

[0033] As shown in FIG. 4(b), the lower edge member (cover member) 72 has an expected wall portion 72a disposed on the indoor side of the newly installed lower frame 22, a finding wall portion 72b extending from the indoor side of the expected wall portion 72a in the outer circumferential direction, and an engaging portion 72c composed of a set of engaging claws extending from the outer peripheral side surface of the expected wall portion 72a in the outer circumferential direction.

[0034] The lower edge member 72 has the engaging portion 72c engaged with the frame member engaging groove 224b of the mounting auxiliary member 224, and the finding wall portion 72b is in contact with the inner circumferential surface of the spacer 225 of the building opening. Depending on the height of the building opening, the spacer 225 may not necessarily be required, and spacers 225 with different height dimensions may also be used.

[0035] (Configuration of the vertical frame part) Regarding the description of the vertical frame part, it will be mainly described with reference to the right vertical frame, and the left vertical frame will be marked with reference numerals in the drawings. The vertical attachment auxiliary member 33 fixed to the existing vertical frame 13 has a prospective wall portion 33a that serves as a reference when installing the new vertical frame 23, as shown in FIG. 2, and an indoor side fixing portion 33b and an outdoor side fixing portion 33c that extend in the outer peripheral direction from the vicinity of both ends of the prospective wall portion 33a indoors and outdoors.

[0036] The vertical attachment auxiliary member 33 is arranged such that the indoor side fixing portion 33b and the outdoor side fixing portion 33c are inserted between the outdoor side of the indoor side wall portion 13b and the indoor side of the outdoor side wall portion 13c of the existing vertical frame 13 so that the prospective wall portion 33a becomes a vertical surface facing the inner circumference, and is fixed to the existing vertical frame 13 by fixing means such as screws.

[0037] The new vertical frame 23 has a vertical frame body 231 made of a metal material and a resin vertical frame 232 arranged on the inner circumference of the vertical frame body 231. The vertical frame body 231 has a prospective wall 231a arranged on the inner circumference of the existing vertical frame 13, and a frame member attachment portion 231b for attaching a vertical frame member 73, which will be described later, is provided on the indoor side of the prospective wall 231a.

[0038] The vertical frame body 231 of the new vertical frame 23 has a plurality of legs on its outer peripheral surface, and is attached to the prospective wall portion 33a of the vertical attachment auxiliary member 33 by fixing means such as screws with the spacer 63 sandwiched therebetween, and a sealing material s23 that closes the gap between the new vertical frame 23 and the existing vertical frame 13 is provided on the outer peripheral surface on the outdoor side.

[0039] In order to improve the heat insulation performance, the fitting of the present embodiment attaches a resin vertical frame member 73 to the indoor side of the new vertical frame 23. However, in order to further improve the heat insulation performance, the attachment structure of the vertical frame member 73 to the frame member attachment portion 231b has been devised. The attachment structure of the vertical frame member 73 will be further described below.

[0040] In the newly installed vertical frame 23 of this embodiment, the vertical picture frame member 73 is attached via a resin attachment auxiliary member 234 attached to the picture frame member attachment portion 231b.

[0041] As shown in Fig. 5(b), the picture frame member attachment portion 231b of the newly installed vertical frame 23 is formed at the indoor side end of the projected wall 231a, and has an indoor side finding wall 231f continuous with the projected wall 231a, and an attachment protrusion 231g extending in the indoor direction from the outer peripheral side end of the indoor side finding wall 221f. An engagement groove 231h is provided on the indoor side surface of the indoor side finding wall 231f.

[0042] The attachment auxiliary member 234 is a long member having a substantially U-shaped cross-section with a length dimension similar to the finding dimension of the newly installed vertical frame 23, and having an insertion groove 234a opening toward the inner peripheral side. An engagement portion 234b capable of slidingly engaging with the engagement groove 231h of the picture frame member attachment portion 231b is provided on the outdoor side.

[0043] The attachment auxiliary member 234 is attached to the vertical frame body 231 by inserting the engagement portion 234b into the engagement groove 231h from the end of the vertical frame body 231 prior to the framing of the newly installed vertical frame 23. As shown in Fig. 5(a), the attachment auxiliary member 234 attached to the vertical frame body 231 has the engagement portion 234b engaged with the engagement groove 231h of the vertical frame body 231, and the bottom wall of the insertion groove 234a is arranged along the attachment protrusion 231g. If necessary, the bottom wall of the insertion groove 234a is fixed to the attachment protrusion 231g by fixing means such as screws.

[0044] As shown in Fig. 5(b), the vertical picture frame member 73 has a projected wall portion 73a arranged on the indoor side of the newly installed vertical frame 23, an angle portion 73b abutted against the opening of the building, a finding wall portion 73c connecting the projected wall portion 73a and the angle portion 73b, and an insertion portion 73d composed of a pair of insertion pieces extending in the outer peripheral direction from the outer peripheral side surface of the projected wall portion 73a.

[0045] The vertical frame member 73 can be attached between the building opening and the newly installed vertical frame 23 while absorbing deformation of the existing vertical frame 13 or the building opening by inserting the insertion portion 73d into the insertion groove 234a of the mounting auxiliary member 234 from the inner peripheral side and abutting the angle portion 73b against the inner peripheral surface of the building opening and fixing it with fixing means such as screws.

[0046] As described above, in the window of this embodiment, a resin mounting auxiliary member is attached to the indoor finding wall of the newly installed frame, and the resin frame member is attached via the mounting auxiliary member. Therefore, the metal part of the newly installed frame can be kept away from the indoor frame member, and heat transfer from the metal part can be suppressed.

[0047] And, in the window of this embodiment, since a mounting protrusion extending in the indoor direction is provided on the indoor finding wall of the newly installed frame to which the resin mounting auxiliary member is attached, elongation, displacement, and tilting of the mounting auxiliary member can be suppressed, and it can be stably attached. At the same time, the mounting auxiliary member can be protected by the mounting protrusion, and the fireproof performance can be improved.

[0048] In addition, by attaching the resin mounting auxiliary member to the indoor finding wall of the newly installed frame by slide engagement from the frame sill, the joining of the metal frame body and the resin mounting auxiliary member can be easily and surely performed. Moreover, the components (the insertion groove of the mounting auxiliary member and the insertion portion of the frame member) for absorbing deformation of the existing vertical frame 13 or the building opening in the remodeling fitting can be composed of only resin members, so the heat insulation performance can be further improved.

[0049] -Other Embodiments- The newly installed frame member in the mounting structure of the frame member may not be provided with a mounting protrusion at the frame member mounting portion. For example, as shown in Fig. 6(a), the newly installed upper frame 21 may be such that the picture frame mounting portion 211b of the upper frame body 211 does not have a mounting ridge. In that case, the mounting auxiliary member 214 may be formed into a large finding dimension shape with a hollow portion 214c formed on the outer periphery to improve the strength, and the engaging portion 214b of the mounting auxiliary member 214 may be slidably engaged with the engaging groove 211h of the picture frame mounting portion 211b of the upper frame body 211 for attachment, and a spacer 61 may be disposed on the outer peripheral side of the hollow portion 214c.

[0050] Similarly, as shown in Fig. 6(b), the newly installed vertical frame 23 may be such that the picture frame mounting portion 231b of the vertical frame body 231 does not have a mounting ridge. In that case, the mounting auxiliary member 234 may be formed into a large finding dimension shape with a hollow portion 234c formed on the outer periphery to improve the strength, and the engaging portion 234b of the mounting auxiliary member 234 may be slidably engaged with the engaging groove 231h of the picture frame mounting portion 231b of the vertical frame body 231 for attachment, and a spacer 63 may be disposed on the outer peripheral side of the hollow portion 234c.

[0051] In addition, the above-described picture frame mounting structure can also be adopted for window types other than sliding windows such as FIX windows.

[0052] For example, in the upper frame portion of the FIX window shown in Fig. 7, a newly installed upper frame 21 having a picture frame mounting portion 211b is attached with a spacer 61 interposed therebetween to an upper mounting auxiliary member 31 fixed to the inner peripheral side of an existing upper frame 11, and an upper picture frame 71 is provided on the indoor side of the newly installed upper frame 21 via a mounting auxiliary member 214 attached to the picture frame mounting portion 211b.

[0053] Also, in the lower frame portion of the FIX window shown in Fig. 7, a newly installed lower frame 22 having a picture frame mounting portion 221b is attached to a lower mounting auxiliary member 32 fixed to the inner peripheral side of an existing lower frame 12, and a lower picture frame 72 is provided on the indoor side of the newly installed lower frame 22 via a mounting auxiliary member 224 attached to the picture frame mounting portion 221b.

[0054] In addition, in the vertical frame portion of the FIX window shown in Fig. 8, a new vertical frame 23 having a picture frame mounting portion 231b is attached with a spacer 63 interposed therebetween to a vertical mounting auxiliary member 33 fixed to the inner peripheral side of the existing vertical frame 13, and a vertical picture frame member 73 is provided on the indoor side of the new vertical frame 23 via a mounting auxiliary member 234 attached to the picture frame mounting portion 231b.

[0055] Furthermore, the mounting structure of the picture frame member can also be adopted for the picture frame members attached to the left and right vertical frames of the side post. In the side post portion shown in Fig. 9, with respect to the vertical mounting auxiliary members 33 fixed to the inner peripheral sides of the existing vertical frames 13, 13 attached to the left and right of the side post 5, a new vertical frame 23 having a picture frame mounting portion 231b is attached with a spacer 63 interposed therebetween, and a vertical picture frame member 73 is provided on the indoor side of the new vertical frame 23 via a mounting auxiliary member 234 attached to the picture frame mounting portion 231b. In the side post portion, the outer peripheral side of the vertical picture frame member 73 is fixed to the vertical member 51 attached to the indoor side of the side post 5, the vertical picture frame member 73 closes the space between the new vertical frame 23 and the vertical member 51, and the space between the left and right vertical picture frame members 73 sandwiching the side post 5 is covered with a cover member 52.

[0056] In addition, the fitting of the embodiment may appropriately arrange a heat-expandable material at appropriate locations as needed. For example, in the case where the new upper frame 21 has a mounting protrusion 211g on the upper frame body 211, a heat-expandable material that expands by heating may be arranged on the outer peripheral side of the mounting protrusion 211g. The above embodiments do not limit the invention described in the claims, and it goes without saying that they are treated as examples.
