[0003] [Patent Document 1] JP 2021-156052 A Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in renovated fittings, it is desirable not only to make the existing frame invisible, but also to protect the existing frame from flames and heat in the event of a fire. The existing frame in the renovated sash described in Patent Document 1 has an outdoor protrusion that protrudes to the outdoor side from the visible surface of the exterior wall. The outdoor visible surface and the inner peripheral visible surface of the outdoor protrusion are covered by the new frame, but the outer peripheral visible surface remains exposed, and there is a concern that the exposed surface may be exposed to flames and heat.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a renovation fixture that can protect the outdoor protruding portion of an existing frame from fire and heat. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the objective, the renovated fitting of the present invention is a renovated fitting in which a new frame is attached to the inside of an existing frame, wherein the existing frame has an outdoor protrusion that protrudes to the outdoor side from the surface of the exterior wall, the new frame has a visible surface cover that covers the outdoor visible surface of the outdoor protrusion and further extends to a position opposite the exterior wall, and a thermally expandable member is provided between the visible surface cover and the exterior wall.

[0007] In addition, the renovated fixture of the present invention is a renovated fixture in which a new frame is attached to the inside of an existing frame, wherein the existing frame has an outdoor protrusion that protrudes toward the outdoors beyond the visible surface of the exterior wall, and the new frame has a visible surface cover that covers the outdoor visible surface of the outdoor protrusion and extends to a position opposite the exterior wall, and a visible surface cover that extends from the visible surface cover toward the exterior wall and covers the outer visible surface of the outdoor protrusion. Effect of the Invention

[0008] With the renovated fittings of the present invention, the outdoor protrusion can be protected from flames and heat by the expansion of the thermally expandable member between the visible surface cover and the exterior wall in the event of a fire, or by having a visible surface cover that covers the visible surface on the outer periphery of the outdoor protrusion.

[0010] Hereinafter, an embodiment of the remodeling fixture according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiment.

[0011] FIG. 1 is a vertical cross-sectional view of the lower frame portion of a remodeled fitting 10A according to the first embodiment. The remodeled fitting 10A is a fitting in which an existing frame 12 is left and a new frame 14 is attached to the inside of the existing frame 12. By not removing the existing frame 12 in the remodeled fitting 10A, construction costs can be reduced. The remodeled fitting 10A is a window frame that supports a sliding shoji screen (not shown). Each frame material of the existing frame 12 is an extruded material formed from a metal such as aluminum material (including alloys). Each frame material of the new frame 14 is a composite structure made of an extruded material formed from a metal such as aluminum material (including alloys) and a resin material. Each frame material is an extruded material and is configured so that the entire length along the longitudinal direction has a substantially uniform cross-sectional shape. The same applies to each attachment, each frame, etc. described later.

[0012] In this application, the prospective direction refers to the indoor / outdoor direction of the remodeled fixture, that is, the direction from indoors to outdoors or the opposite direction. The prospective surface refers to a surface that extends along the prospective direction. The visible direction refers to a direction perpendicular to the prospective direction, and in the case of a vertical frame that is long in the vertical direction, it refers to the left-right direction perpendicular to the longitudinal direction, and in the case of a bottom frame that is long in the horizontal direction, it refers to the up-down direction perpendicular to the longitudinal direction. The visible surface refers to a surface that is along the visible direction.

[0013] The existing frame 12 is framed on all four sides by a bottom frame 16, an top frame 18 (see Figure 3), and left and right vertical frames 20 (see Figure 4). The new frame 14 is framed on all four sides by a bottom frame 22, an top frame 24 (see Figure 3), and left and right vertical frames 26 (see Figure 4). The vertical frames 20, 26 have some differences, but only one is shown because the outer periphery is symmetrical on the left and right. The renovated fixture 10A is fixed from the building's framework 28 to the exterior wall 30. The framework 28 in Figure 1 forms part of the wall. In Figure 1, the framework 28 has a two-step shape toward the exterior wall 30.

[0014] As shown in Figure 1, the lower frame 16 of the existing frame 12 corresponds to the stepped shape of the body 28 and has an indoor L-shaped wall 16a, an indoor rail base 16b, an outdoor rail base 16c, and an outdoor protrusion 16d. The L-shaped wall 16a covers the upper end of the body 28 from the inner circumference side visible surface to the visible surface. The indoor rail base 16b has a roughly rectangular cross section and is located below the L-shaped wall 16a and on the outdoor side, with an inner rail 16e provided at its upper part. The outdoor rail base 16c is located on the outdoor side and slightly outer circumference side than the indoor rail base 16b, and an outer rail 16f is provided at its upper part.

[0015] The outdoor rail base 16c and the outdoor protruding part 16d have the same outer peripheral side wall, forming a common cavity. The gap between the outdoor rail base 16c and the exterior wall 30 is filled with a sealant 32 and a backup material 34. The sealant 32 is also considered as part of the exterior wall 30. The outdoor protruding part 16d has a slightly smaller visible width than the outdoor rail base 16c, and protrudes to the outdoor side from the visible surface of the exterior wall 30. The outdoor protruding part 16d's outdoor visible wall 16g protrudes slightly upward and downward. The outdoor protruding part 16d is mainly provided in wooden buildings. In other words, in wooden buildings, with the shift to dry exterior walls such as siding, a shape like the outdoor protruding part 16d protruding from the exterior wall 30 (semi-external fitting) is common so that the exterior wall can be framed with sashes without using a dripboard.

[0016] The lower frame 22 of the new frame 14 is based on a metal profile 36. The metal profile 36 is usually made of aluminum or the like and is heat resistant. The metal profile 36 has an L-shaped portion 36a on the indoor side, a projection wall 36b protruding from the L-shaped portion 36a toward the outdoor side while forming a number of small steps, and a cavity forming wall 36c on the outdoor side that forms a cavity together with the projection wall 36b and has high strength. The indoor side protruding piece of the L-shaped portion 36a is fixed to the main body 28 by a screw 38. An inner rail 36d and an outer rail 36e are aligned in the projection direction and protrude upward in the middle of the projection wall 36b. The inner rail 36d and the outer rail 36e support the inner and outer screens. A screen rail 36f protrudes upward from the outdoor end of the projection wall 36b. A pocket portion 36g that opens toward the outdoor side is formed in the outdoor side of the cavity forming wall 36c. Hooks 36h are formed at the upper and lower ends of the pocket portion 36g. The pocket portion 36g and the outdoor side observation wall 16g are aligned substantially vertically.

[0017] A reinforcing piece 48 is fixed to the pocket portion 36g by a screw (fixing device) 50. The screws in this embodiment may be replaced with other fixing devices. The reinforcing piece 48 is made of a metal material such as stainless steel, and a plurality of reinforcing pieces 48 are provided along the longitudinal direction of the lower frame 22. The reinforcing piece 48 is slightly bent in the middle in the projection direction in a crank shape, so that it does not interfere with the outdoor-side visible wall 16g. A long hole is formed in the upper part of the reinforcing piece 48, and the reinforcing piece 48 is fixed inside the pocket portion 36g by a screw 50, so that the downward protruding length can be adjusted. The lower part of the reinforcing piece 48 protrudes from a lower hole formed in the pocket portion 36g and abuts against the upper surface of the lower frame 16 to ensure strength. The reinforcing piece 48 abuts against the upper surface of the outdoor protruding portion 16d of the lower frame 16.

[0018] The lower frame 22 further has a frame 40, a first inner periphery cover 42, a second inner periphery cover 44, and an attachment 46. The frame 40, the first inner periphery cover 42, and the second inner periphery cover 44 are made of resin and cover the inner periphery side and indoor side of the metal profile 36 with a gap therebetween, improving heat insulation and design and preventing condensation. The frame 40 and the first inner periphery cover 42 are fixed with screws 47, and cover the indoor side portion of the metal profile 36 beyond the inner rail 36d. The gap between the frame 40 and the main body 28 is covered with a gap cover 52.

[0019] The attachment 46 is usually made of aluminum or other material and is heat resistant. The same is true for each attachment described below. The attachment 46 is fixed to the hook 36h of the pocket portion 36g, and has an upper fixing portion 46a and a face cover 46b that protrudes downward from the fixing portion 46a. The fixing portion 46a and the face cover 46b are continuous in appearance. Two hooks 46c, one above and one below, are formed on the fixing portion 46a. The fixing portion 46a covers the pocket portion 36g and the screw 50 by engaging the hook 46c with the hook 36h, improving the design.

[0020] The sight cover 46b covers the outdoor sight wall 16g of the outdoor protrusion 16d and extends outward to a position facing the exterior wall 30. A break groove 46d extending in the longitudinal direction is formed in approximately half of the tip side (lower side in this case) of the indoor side of the sight cover 46b. A plurality of break grooves 46d are formed at close intervals along the sight direction.

[0021] A thermal expansion member 54 is provided at the tip of the visible surface cover 46b at the indoor side end facing the exterior wall 30. The thermal expansion member 54 is a non-combustible or flame-retardant fireproof member that expands with heat, for example, a heat-foaming material such as graphite that expands with heat. The thermal expansion member 54 may be either a solid adhesive type or a liquid type that is applied and dried. The thermal expansion member 54 expands approximately in the direction perpendicular to the surface to which it is attached, but also expands slightly in the direction along the surface. The thermal expansion member 54 is preferably provided on the visible surface cover 46b, but may be provided on the exterior wall 30 depending on the construction conditions such as the surface condition of the exterior wall 30. In other words, the thermal expansion member 54 may be provided between the visible surface cover 46b and the exterior wall 30.

[0022] FIG. 2 is a partially enlarged vertical cross-sectional view of the lower frame portion of the remodeling fitting 10A when heated. Normally (when not heated), the exterior side and inner periphery side of the existing frame 12 are covered by the new frame 14, while only the exterior protrusion 16d is exposed on the outer periphery side. However, as shown in FIG. 2, when heat is received during a fire, the thermal expansion member 54 expands and closes the gap with the exterior wall 30. As a result, the gap between the existing frame 12 and the new frame 14 is completely blocked during a fire, preventing smoke and flames from entering from the outside, and protecting the exterior protrusion 16d. In addition, the thermal expansion member 54 has a heat insulating effect and prevents the outdoor protrusion 16d from being directly heated. The outdoor protrusion 16d, which is protected from heating, can continue to support the new frame 14 via the reinforcing piece 48. It is preferable that the new frame 14 covering the inner periphery side and the exterior side of the outdoor protrusion 16d has a fireproof structure.

[0023] The new frame 14 has a certain degree of dimensional leeway, and the reinforcing pieces 48 with long holes provide an adjustment margin, so it can be applied to existing frames 12 of various sizes and shapes. In addition, since the front cover 46b has multiple break-off grooves 46d, the range of application can be further expanded by breaking off any one of the break-off grooves 46d. The range of application can be further expanded by providing a selection of attachments 46 of various sizes. However, depending on the design conditions, the attachments 46 and reinforcing pieces 48 may be integral with the metal profile 36.

[0024] 3 is a vertical cross-sectional view of the upper frame part of the remodeling fitting 10A. Hereinafter, the same reference numerals will be used to designate parts that are substantially similar to the components of the lower frame part of the remodeling fitting 10A, and detailed descriptions thereof will be omitted.

[0025] The upper frame 18 of the existing frame 12 has an L-shaped wall 18a on the indoor side, an indoor rail base 18b, an outdoor rail base 18c, and an outdoor protrusion 18d. An inner rail 18e is provided at the lower part of the indoor rail base 18b. The outdoor rail base 18c is located on the outdoor side of the indoor rail base 18b, and an outer rail 18f is provided below. The inner rail 18e and the outer rail 18f are not used, and are cut short due to layout requirements with the new frame 14. The gap between the outdoor rail base 18c and the exterior wall 30 is filled with a sealant 32 and a backup material 34. The outdoor protrusion 18d protrudes outdoors beyond the visible surface of the exterior wall 30. The outdoor protrusion 18d's outdoor visible wall 18g is a screen rail.

[0026] The upper frame 24 of the new frame 14 is based on a metal profile 56. The metal profile 56 has two side-by-side cavity forming sections 56a, a fixed piece 56b protruding from the cavity forming section 56a to the inside of the room, a visible wall 56c protruding to the outside, and an inner rail 56d, an outer rail 56e, and a screen rail 56f that are lined up in the visible direction and protrude downward. The screen rail 56f forms the visible wall on the outside side of the upper frame 24. The fixed piece 56b of the upper frame 24 is fixed to the main body 28 by screws 38 via spacers 59.

[0027] An L-shaped bracket 58 is provided between the upper frame 24 and the upper frame 18. The L-shaped bracket 58 is made of aluminum, for example. The long side 58a of the L-shaped bracket 58 extends in the forward direction, and the vicinity of the indoor end is fixed to the main body 28 by the screw 38. The short side 58b of the L-shaped bracket 58 is located almost directly above the screen rail 56f and forms a blind wall.

[0028] The upper frame 24 further has a frame 40, an inner periphery cover 60, an attachment 62, and an attachment cover 64. The frame 40 and the inner periphery cover 60 are fixed with screws 47, and cover the indoor side portion of the metal profile 56 beyond the inner rail 56d.

[0029] The attachment 62 is fixed to the short side portion 58b of the L-shaped bracket 58 with screws 50, and has a lower pocket portion 62a, a lower sighting surface cover portion 62b that protrudes diagonally upward from the pocket portion 62a, an upper sighting surface cover portion 62c, and a sighting surface cover 62d.

[0030] The pocket portion 62a has the same shape as the pocket portion 36g described above, and the attachment cover 64 serves as a lid to cover the internal screws 50. The sight cover lower portion 62b gently slopes upward toward the indoor side, and covers the outdoor sight wall 18g of the outdoor protrusion 18d. The sight cover upper portion 62c extends further outward from the sight cover lower portion 62b to a position facing the exterior wall 30. The sight cover upper portion 62c is parallel to the exterior wall 30, and a thermal expansion member 54 is provided on the indoor side to seal the gap with the exterior wall 30 in the event of a fire.

[0031] The front surface cover 62d extends from the upper end of the front surface cover upper part 62c toward the exterior wall 30 and covers almost the entire outer peripheral side front surface of the outdoor protrusion 18d. A plurality of break grooves 62e are formed in the front surface cover 62d, and the length between the front surface cover 62d and the exterior wall 30 can be adjusted by breaking off any one of the break grooves 62e. The front surface cover 62d whose length has been adjusted by the break grooves 62e may not have a completely zero gap between the front surface cover 62d and the exterior wall 30, but the gap is sealed by the sealant 65 to prevent water from entering.

[0032] 4 is a cross-sectional view of the vertical frame portion of the remodeled fitting 10A. The vertical frame 20 of the existing frame 12 has an L-shaped wall 20a on the indoor side, a base 20b, and an outdoor protrusion 20c. The base 20b and the outdoor protrusion 20c are continuous in the front direction. The gap between the base 20b and the exterior wall 30 is filled with a sealant 32 and a backup material 34. The outdoor protrusion 20c protrudes to the outdoor side beyond the visible surface of the exterior wall 30. An outdoor-side visible wall 20d is provided at the tip of the outdoor protrusion 20c.

[0033] The vertical frame 26 of the new frame 14 is based on a metal profile 66. The metal profile 66 has a cavity forming portion 66a, a fixing piece 66b protruding inward from the cavity forming portion 66a, a concealed wall 66c protruding to the outdoor side, an outdoor-side visible wall 66d, and a protruding piece 66e. The protruding piece 66e is a small piece protruding to the outer periphery near the outdoor end. The protruding piece 66e has a recess 66f recessed toward the indoor side. The fixing piece 66b of the vertical frame 26 is fixed to the main body 28 by screws 38 via spacers 59.

[0034] The vertical frame 26 further includes a frame 40, an inner peripheral cover 68, and an attachment 70. The frame 40 and the inner peripheral cover 68 are fixed together with screws 47, which cover the spacers 59 and the screws 38.

[0035] The attachment 70 is fixed to the tip of the metal profile 66 with a screw 50. The attachment 70 has an irregular L-shape and has a fixing part 70a on the short side that forms the visible surface on the inner circumference side, and a sight surface cover 70b on the long side that extends from the fixing part 70a to the outer circumference side to form the sight surface. The fixing part 70a is fixed with a screw 50 in a state where the tip fits into the recess 66f and the middle part is supported by the outdoor sight wall 66d. A rectangular recess 70c is formed in the middle of the sight surface cover 70b toward the indoor side. The tip of the sight surface cover 70b forms a small bent part 70d toward the indoor side. The sight surface cover 70b covers the outdoor sight wall 20d of the outdoor protrusion 20c and further extends to the outer circumference side to a position facing the exterior wall 30. A thermal expansion member 54 is provided on the indoor side of the tip of the visible surface cover 70b so as to contact the bent portion 70d, and seals the gap with the exterior wall 30 in the event of a fire.

[0036] Fig. 5 is a vertical cross-sectional view of the lower frame part of the remodeling fitting 10B according to the second embodiment. Fig. 6 is a partially enlarged vertical cross-sectional view of the lower frame part of the remodeling fitting 10B when heated. The lower frame part of the remodeling fitting 10B replaces the attachment 46 in the lower frame part of the remodeling fitting 10A (see Fig. 1) with another attachment 72.

[0037] The attachment 72 is fixed to the hook 36h of the pocket portion 36g and has an upper fixing portion 72a, a sight surface cover 72b protruding downward from the fixing portion 72a, and a sight surface cover 72c. The fixing portion 72a and the sight surface cover 72b are the same as the fixing portion 46a and the sight surface cover 46b described above. The sight surface cover 72b covers the outdoor-side sight wall 16g of the outdoor protrusion 16d and further extends outward to a position facing the exterior wall 30.

[0038] The visible surface cover 72c extends from the lower end of the visible surface cover 72b toward the exterior wall 30 and covers almost the entire outer peripheral side visible surface of the outdoor protrusion 16d. The distance between the visible surface cover 72c and the outdoor protrusion 16d is short. A thermal expansion member 54 is provided on the surface of the visible surface cover 72c facing the outdoor protrusion 16d. As shown in Figure 6, in the event of a fire, the thermal expansion member 54 expands to seal the gap with the outdoor protrusion 16d.

[0039] A plurality of break grooves 72d are formed in the front surface cover 72c, and the length between the front surface cover 72c and the exterior wall 30 can be adjusted by breaking off any one of the break grooves 72d. The front surface cover 72c whose length has been adjusted by the break grooves 72d may not have a gap between the front surface cover 72c and the exterior wall 30 completely zero, but in the event of a fire, the thermal expansion member 54 expands somewhat in the front direction to cover almost the entire surface of the outer periphery of the outdoor protrusion 16d, and the outdoor protrusion 16d is protected from heat. Of course, the front surface cover 72c may be molded so as to just contact the exterior wall 30 without using the break grooves 72d. When there is almost no gap between the front surface cover 72c and the exterior wall 30, the front surface of the outer periphery of the outdoor protrusion 16d is protected quite reliably by the front surface cover 72c, so the thermal expansion member 54 can be omitted, but it is more preferable to provide the thermal expansion member 54.

[0040] The thermal expansion member 54 is preferably provided on the front surface cover 72c, but may be provided on the side of the outdoor protrusion 16d depending on the construction conditions such as the surface condition of the outer peripheral side front surface of the outdoor protrusion 16d. In other words, the thermal expansion member 54 may be provided between the front surface cover 72c and the outdoor protrusion 16d.

[0041] 7 is a vertical cross-sectional view of the upper frame portion of the remodeled fitting 10B. The upper frame portion of the remodeled fitting 10B replaces the attachment 62 in the upper frame portion of the remodeled fitting 10A (see FIG. 3) with another attachment 74.

[0042] The attachment 74 has a lower pocket portion 74a, a lower portion 74b of the visible surface cover, an upper portion 74d of the visible surface cover, and a hidden surface cover 74d. This corresponds to the pocket portion 62a, the lower portion 62b of the visible surface cover, the upper portion 62c of the visible surface cover, and the hidden surface cover 62d in the attachment 62 described above. However, the upper portion 74c of the visible surface cover is shorter than the upper portion 62c of the visible surface cover, and is approximately the thickness of the thermal expansion member 54, and the distance between the hidden surface cover 74d and the outdoor protrusion 18d is short. In the remodeled fitting 10B, the thermal expansion member 54 is provided on the inner periphery side of the hidden surface cover 62d, that is, on the surface facing the outer peripheral visible surface of the outdoor protrusion 18d, and closes the gap with the outdoor protrusion 18d in the event of a fire. The hidden surface cover 74d has a plurality of break grooves 74e formed therein, and the length between the cover and the exterior wall 30 can be adjusted by breaking off any one of the break grooves 74e.

[0043] 8 is a cross-sectional view of the vertical frame portion of the remodeled fitting 10B. In the vertical frame portion of the remodeled fitting 10B, the attachment 70 in the vertical frame portion of the remodeled fitting 10A (see FIG. 4) is replaced with another attachment 76.

[0044] The attachment 76 has a fixed portion 76a, a sighting surface cover 76b, and a hidden surface cover 76d. The fixed portion 76a and the sighting surface cover 76b correspond to the fixed portion 70a and the sighting surface cover 70b of the attachment 70 described above. A recess 76c similar to the recess 70c described above is formed in the middle of the sighting surface cover 76b. The hidden surface cover 76d is an extension of the bent portion 70d described above, and extends to the vicinity of the exterior wall 30. A plurality of break grooves 76e are formed in the hidden surface cover 76d, and the length between the exterior wall 30 can be adjusted by breaking off any one of the break grooves 76e. The hidden surface cover 76b is shorter than the sighting surface cover 70b, and the distance between the hidden surface cover 76d and the outdoor protrusion 20c is short. In the renovated fixture 10B, the thermally expandable member 54 is provided on the inner side of the recessed surface cover 76d, i.e., on the surface facing the outer recessed surface of the outdoor protrusion 20c, and seals the gap with the outdoor protrusion 20c in the event of a fire.

[0045] Fig. 9 is a vertical cross-sectional view of a first modified example of the lower frame part of the remodeled fitting 10B. In the lower frame part of the remodeled fitting 10B shown in Fig. 5, the thermal expansion member 54 is provided on the inner surface cover 72c, but in the example shown in Fig. 9, it is provided on the indoor side of the visible surface cover 72b. The thermal expansion member 54 is located opposite the exterior wall 30 and the outdoor visible wall 16g, and closes the gap between them in the event of a fire.

[0046] 10 is a vertical cross-sectional view of a second modified example of the lower frame portion of the remodeled fitting 10B. In this modified example, the attachment 72 has a slanted wall 72e between the visible surface cover 72b and the invisible surface cover 72c. The slanted wall 72e is inclined at 45 degrees downward toward the indoor side. In the lower frame portion of this modified example, a thermal expansion member 54 is provided on the indoor side of the slanted wall 72e, and closes the gap between the exterior wall 30 and the outdoor protrusion 16d in the event of a fire.

[0047] 11 is a vertical cross-sectional view of a third modified example of the lower frame part of the remodeled fitting 10B. In the lower frame part of this modified example, the thermal expansion member 54 is provided directly below the fixed part 72a on the indoor side of the face cover 72b, and in the event of a fire, it closes the gap between the upper part of the outdoor face wall 16g and the lower part of the reinforcing piece 48. A small rib 72f that supports the thermal expansion member 54 protrudes from the face cover 72b to the indoor side.

[0048] 12 is a vertical cross-sectional view of a fourth modified example of the lower frame portion of the remodeled fitting 10B. In this modified example, when the thermal expansion member 54 is not provided for some reason in the remodeled fitting 10A shown in FIG. 1, the attachment 46 is left in place and an attachment 78 provided with the thermal expansion member 54 is attached later.

[0049] The attachment 78 is fixed to the outdoor side of the fixing portion 46a of the attachment 46 with a screw 80, and has an upper pocket portion 78a, a front surface cover 78b protruding downward from the pocket portion 78a, and an inner surface cover 78c.

[0050] The pocket portion 78a is slightly smaller than the pocket portion 36g, and the attachment cover 82 acts as a lid on the outdoor side to cover the internal screw 80. The screw 80 is screwed into the fixing portion 46a and the pocket portion 36g from the bottom of the pocket portion 78a. The screw 80 and the screw 50 are shifted in the depth direction of the paper so as not to interfere with each other. The sight surface cover 78b extends further to the outer periphery than the lower end of the sight surface cover 46b. The sight surface cover 78c extends from the lower end of the sight surface cover 78b to the indoor side, and extends beyond the sight position of the sight surface cover 46b toward the outer wall 30 to cover almost the entire outer periphery side sight surface of the outdoor protrusion 16d. The thermal expansion member 54 is provided on the inner periphery side of the sight surface cover 78c, that is, on the surface facing the outer periphery sight surface of the outdoor protrusion 16d, and closes the gap with the outdoor protrusion 16d in the event of a fire. In the example of FIG. 12, the thermal expansion member 54 is provided on the indoor side relative to the prospective position of the front cover 46b.

[0051] A plurality of break grooves 78d are formed in the front surface cover 78c, and by breaking off any one of the break grooves 78d, it is possible to adjust the length between the front surface cover 78c and the outer wall 30. When the length of the front surface cover 78c is adjusted by the break grooves 78d, the gap between the front surface cover 78c and the outer wall 30 may not be completely zero, but the gap is closed by the sealing material 65.

[0052] FIG. 13 is a vertical cross-sectional view of a modified upper frame portion of the remodeled fitting 10B. In this modified example, when the attachment 83 is provided instead of the attachment 62 in the remodeled fitting 10A shown in FIG. 3, the attachment 78 provided with the thermal expansion member 54 is attached later while leaving the attachment 83. The attachment 83 has a lower pocket portion 83a and an inclined wall 83b protruding obliquely upward from the pocket portion 83a. The pocket portion 83a is the same as the pocket portion 62a (see FIG. 3) described above, and is closed by the attachment cover 64. The pocket portion 83a is fixed by the same screw 50 as in FIG. 3. There is almost no gap between the upper end of the inclined wall 83b and the upper end of the outdoor-side visible wall 18g, and it is filled with a sealant. The thermal expansion member 54 is not provided on the inclined wall 83b.

[0053] The attachment 78 in this modification is the one shown in Fig. 12, but turned upside down. The screw 80 is screwed from the bottom of the pocket 78a into the attachment cover 64 and the pocket 83a to fix the attachment 78. The sight surface cover 78b extends slightly above the upper end of the outdoor sight wall 18g. The sight surface cover 78c extends from the upper end of the sight surface cover 78b toward the exterior wall 30, covering almost the entire outer circumferential surface of the outdoor protrusion 18d. The thermal expansion member 54 is provided on the inner circumferential side of the sight surface cover 78c, that is, on the surface facing the outer circumferential surface of the outdoor protrusion 18d, and closes the gap with the outdoor protrusion 18d in the event of a fire.

[0054] Fig. 14 is a cross-sectional view of a modified vertical frame portion of the remodeled fitting 10B. This modified example is for cases where the visible surface cover 70b of the remodeled fitting 10A shown in Fig. 4 is not wide enough to accommodate the thermal expansion member 54, and the attachment 84 provided with the thermal expansion member 54 is attached later while leaving the attachment 70 in place.

[0055] The attachment 84 is fixed to the outdoor side of the sight surface cover 70b with screws 88, and has a pocket portion 84a, a sight surface cover 84b protruding from the pocket portion 84a toward the outer periphery, and a sight surface cover 84c.

[0056] The pocket portion 84a is covered by an attachment cover 86, which serves as a lid and covers the internal screw 88. The screw 80 is screwed into the sight cover 70b from the bottom of the pocket portion 84a. A spacer 90 is interposed between the pocket portion 84a and the sight cover 70b to provide stability. The sight cover 84b is shaped to slope toward the outdoor side in two stages toward the outer periphery, and the inner periphery part in particular is curved in a slight arc shape, providing a suitable design. The sight cover 84c extends from the lower end of the sight cover 84b toward the outer wall 30 and covers almost the entire outer periphery side sight surface of the outdoor protrusion 20c. The thermal expansion member 54 is provided on the inner periphery side of the sight cover 84c, that is, on the surface facing the outer periphery sight surface of the outdoor protrusion 20c, and closes the gap with the outdoor protrusion 20c in the event of a fire. A plurality of break grooves 84d are formed in the front surface cover 84c, and the length between the front surface cover 84c and the outer wall 30 can be adjusted by breaking off any one of the break grooves 84d.

[0057] FIG. 15 is a vertical cross-sectional view of the upper frame portion of the remodeling fitting 10C according to the third embodiment. The remodeling fitting 10C is a door frame for an entrance or the like. As shown in FIG. 15, in the remodeling fitting 10C, a new upper frame 94 is provided on the inner periphery of an existing upper frame 92. A part of the existing upper frame 92 has an outdoor protruding portion 92a that protrudes from the visible surface of the exterior wall 30 to the outdoor side. The new upper frame 94 is a composite frame consisting of a metal frame 94a on the outdoor side and a resin frame 94b on the indoor side, and is fixed by a reinforcing piece 96 or the like. The reinforcing piece 96 is crank-shaped, and the indoor side portion is fixed to the frame 28 by a screw 38. The metal frame 94a protrudes to the outdoor side from the existing upper frame 92. Spacers 98 of different thicknesses are provided between the existing upper frame 92 and the new upper frame 94, and between the reinforcing piece 96 and the frame 28. The reinforcing piece 96, the screw 38, and the spacer 98 are covered by a frame 100. A sealing material 32 and a backup material 34 are provided on the outdoor side between the existing upper frame 92 and the new upper frame 94.

[0058] An attachment 78 is fixed to an outdoor-facing visible surface 94c of the new upper frame 94. A pocket portion 78a of the attachment 78 is covered by an attachment cover 82. The attachment 78 and attachment cover 82 shown in Fig. 15 differ from those shown in Fig. 13 in some of their dimensions and detailed shapes, but are made of the same functional material and are therefore given the same reference numerals.

[0059] The pocket portion 78a of the attachment 78 is fixed to the outdoor sight surface 94c by the screw 80. The sight surface cover 78b extends above the existing upper frame 92. The sight surface cover 78c extends from the upper end of the sight surface cover 78b toward the exterior wall 30 and covers almost the entire outer periphery sight surface of the outdoor protrusion 92a. The thermal expansion member 54 is provided on the inner periphery side of the sight surface cover 78c, i.e., on the surface facing the outer periphery sight surface of the outdoor protrusion 92a, and closes the gap with the outdoor protrusion 92a in the event of a fire.

[0060] Fig. 16 is a cross-sectional view of the vertical frame portion of the remodeled fitting 10C. As shown in Fig. 16, in the remodeled fitting 10C, a new vertical frame 104 is provided on the inner periphery of an existing vertical frame 102. A part of the existing vertical frame 102 has an outdoor protruding part 102a that protrudes to the outdoor side from the visible surface of the exterior wall 30. The new vertical frame 104 is a composite frame consisting of a metal frame 104a on the outdoor side and a resin frame 104b on the indoor side, and is fixed with a reinforcing piece 96 or the like. Another reinforcing piece 106 is further fixed between the existing vertical frame 102 and the new vertical frame 104, so that the door frame load can be reliably supported.

[0061] An attachment 84 is fixed to an outdoor facing surface 104c of the new vertical frame 104. A pocket portion 84a of the attachment 84 is covered by an attachment cover 86. The attachment 84 and attachment cover 86 shown in Fig. 16 differ from those shown in Fig. 14 in some of their dimensions and detailed shapes, but are made of the same functional material and are therefore given the same reference numerals.

[0062] The pocket portion 84a of the attachment 84 is fixed to the outdoor sight surface 104c by the screw 80. The sight surface cover 84b extends to the outer periphery side beyond the existing vertical frame 102. The sight surface cover 84c extends from the end of the sight surface cover 84b toward the exterior wall 30 and covers almost the entire outer periphery side sight surface of the outdoor protrusion 102a. The thermally expandable member 54 is provided on the inner periphery side of the sight surface cover 84c, i.e., on the surface facing the outer periphery sight surface of the outdoor protrusion 102a, and closes the gap with the outdoor protrusion 102a in the event of a fire.

[0063] In the remodeled fixture 10C shown in Figures 15 and 16, a thermal expansion member 54 is provided on the visible wall of the attachment to seal the gap with the outdoor protrusion, but the visible wall of the attachment may be provided close to the exterior wall 30 and a thermal expansion member 54 may be provided on the visible wall to seal the gap with the exterior wall 30.

[0064] The present invention is not limited to the above-described embodiment, and can of course be freely modified without departing from the spirit and scope of the present invention.
