Description

[Technical Field]

[0001] The present disclosure relates to retrofit fittings. [Background technology]

[0002] Conventionally, a covering method has been adopted for renovating openings in buildings through renovations, etc., in which new fixtures are installed in the openings. In the renovated fixtures renovated using this covering method, a new frame is attached to the inner periphery of the existing frame attached to the opening of the building (see, for example, Patent Document 1).

[0003] In renovation fittings, new frames are provided with extension plates that extend outward in the viewing direction. Therefore, when attaching the new frame to the existing frame from the inside of the room, the extension plates of the new frame will hit the existing frame. Therefore, the new frame may be tilted and inserted through the opening of the existing frame from the inside of the room, extending it to the outside, and then pulled toward the existing frame to attach the new frame to the existing frame.

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-64432 Summary of the Invention [Problem to be solved by the invention]

[0005] In renovations of building materials, a new frame is sometimes inserted through an opening in an existing frame from the inside of the room, pulled out to the outside, and then attached to the existing frame. In this case, if a grille or shutter is installed on the outside of the room, the new frame may hit the grille or shutter when the new frame is inserted through the opening in the existing frame from the inside of the room and pulled out to the outside, which could impair workability. Therefore, there is a demand for improved workability.

[0006] The present disclosure aims to provide renovation fittings that can improve workability. [Means for solving the problem]

[0007] The present disclosure relates to a renovation fitting that is attached to an existing frame installed in an opening in a building, and that comprises a new frame that is assembled around all four sides, and an attachment frame that is arranged between the new frame and the existing frame, and the attachment frame has an attachment frame main body that is attached around all four sides to the outer periphery of the new frame, and a divided attachment part that is arranged on top of the attachment frame main body and is thereby arranged between the existing upper frame of the existing frame and the attachment frame main body.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. The remodeling fitting 1 according to this embodiment is a remodeling fitting 1 for renovation, which is formed by newly installing new members while leaving the existing frame 6 fixed to the building 100 attached to the building 100.

[0010] In this specification, "prospect direction" refers to the face direction of the surface material of the shoji screen 10 in the remodeled fitting 1 placed in an opening formed in the wall of the building 100, and "prospect direction" refers to the thickness direction of the surface material (i.e., the depth direction). The "prospect direction" also refers to the indoor / outdoor direction. In the drawings, the outdoor side of the remodeled fitting 1 is the outdoor side X1, and the indoor side of the remodeled fitting 1 is the indoor side X2. The horizontal direction of the remodeled fitting 1 is referred to as the "left-right direction."

[0011] As shown in Figures 1 to 3, the remodeled fitting 1 according to this embodiment is a remodeled sash of a double sliding window type that is installed in an opening of a building 100. The remodeled fitting 1 is attached to an existing frame 6 that is provided in the opening of the building 100.

[0012] As shown in Figures 1 to 8, the renovated fitting 1 comprises a new frame 2, an attachment frame 30 that is attached to the inside of the existing frame 6 while being attached to the outer periphery of the new frame 2, indoor decorative members 41, 42, 43, outdoor decorative covers 51, 52, 53 (outdoor cover materials), and shoji screens 10, 10 that can be slidably fitted within the new frame 2.

[0013] The attachment frame 30 has an attachment frame main body 3 that surrounds the new frame 2 on all four sides, and a divided attachment section 8 that is placed on top of the attachment frame main body 3. The existing frame 6 is installed at an opening in the building 100. The new frame 2 is attached to the inner periphery of the existing frame 6 to which the divided attachment section 8 is attached, with the attachment frame main body 3 attached to the outer periphery. The attachment frame 30 is placed between the existing frame 6 and the new frame 2.

[0014] First, we will explain the configuration of the existing frame 6. As shown in Figures 2 and 3, the existing frame 6 is provided inside the opening of the building 100 and is formed in the shape of a rectangular frame. The existing frame 6 includes an existing upper frame 61, an existing lower frame 62, and existing vertical frames 63 on the left and right.

[0015] 2, the existing upper frame 61 is attached to the upper side of the opening of the building 100, and has guide rails 611, 612 (existing upper frame guide rails) for the existing shoji screen that are erected downward. The inside X2 portion of the existing upper frame 61 is fixed to the building 100 (frame).

[0016] The existing lower frame 62 is attached to the lower side of the opening of the building 100, and has guide rails 621, 622 for the existing shoji screen that stand upright facing upward. The inside X2 portion of the existing lower frame 62 is fixed to the building 100 (frame).

[0017] 3, the existing vertical frames 63 are attached to the left and right vertical sides of the outdoor side X1 of the opening of the building 100. The indoor side X2 portion of the existing vertical frames 63 is fixed to the building 100 (frame).

[0018] As shown in Figure 8, the new frame 2 is attached to the divided attachment parts 8 attached to the existing frame 6, with the attachment frame main body 3 attached to the outer periphery. The new frame 2 is made up of four parts and is attached to the inner periphery of the existing frame 6 via the attachment frame 30.

[0019] The new frame 2 includes a new upper frame 21, a new lower frame 22, and left and right new vertical frames 23. When the new frame 2 is assembled around all four sides, it is fixed with screws at the parts where the new upper frame 21, new lower frame 22, and left and right new vertical frames 23 join together. The attachment frame main body 3 includes an attachment upper frame 31, an attachment lower frame 32, and left and right vertical attachment frames 33.

[0020] The new upper frame 21 is attached to the inner periphery of the existing upper frame 61, with the attachment upper frame 31 sandwiched between them, as shown in Figure 2, when the new frame 2, with the attachment frame body 3 attached to the outer periphery, is attached to the existing frame 6. The new upper frame 21 has guide rails 211, 212 on the upper side of the shoji screens 10, 10 that are erected downward.

[0021] When the new frame 2, with the attachment frame body 3 attached to the outer periphery, is attached to the existing frame 6, the new sill 22 is attached to the inner periphery of the existing sill 62, with the attachment sill 32 sandwiched between them, as shown in Figure 2. The new sill 22 has guide rails 221, 222 on the lower side of the shoji screens 10, 10 that are erected facing upward.

[0022] The new vertical frame 23 is attached to the inner periphery of the existing vertical frame 63, with the attachment frame main body 3 attached to the outer periphery, as shown in Figure 3, with the attachment vertical frame 33 sandwiched between them.

[0023] The new upper frame 21, the new lower frame 22, and the new vertical frame 23 are formed of, for example, a metal material or a resin material. As shown in Figures 2 and 3, resin angle members 213, 223, and 233 are provided on the indoor side X2 of the new upper frame 21, the new lower frame 22, and the new vertical frame 23, respectively. The resin angle members 213, 223, and 233 are each arranged with a gap between them and the frame member 101.

[0024] The above-mentioned new frame 2 (new upper frame 21, new lower frame 22, and left and right new vertical frames 23) is attached to the inner periphery of the existing frame 6 (existing upper frame 61, existing lower frame 62, and left and right existing vertical frames 63), with the attachment frame main body 3 (attachment upper frame 31, attachment lower frame 32, and left and right vertical attachment frames 33) arranged around the outer periphery.

[0025] As shown in Figure 9, the attachment frame 30 has an attachment frame main body 3 and divided attachment parts 8. The attachment frame main body 3 is attached to the outer periphery of the new frame 2 in a four-way configuration, and is then attached to the inner periphery of the existing frame 6 to which the divided attachment parts 8 are attached. The attachment frame main body 3 is attached to the outer periphery of the new frame 2 in a four-way configuration.

[0026] The divided attachment part 8 is disposed above the attachment frame main body 3, and is thereby disposed between the existing upper frame 61 and the attachment frame main body 3. The divided attachment part 8 extends in the longitudinal direction of the existing upper frame 61 below the existing upper frame 61. As shown in Fig. 10, the divided attachment part 8 has an indoor / outdoor extending plate part 81, a divided side horizontal gutter structure part 82, an outdoor vertical extending plate part 83, and an outdoor upward extending plate part 84 (an outdoor facing direction extending plate part).

[0027] The indoor / outdoor extending plate portion 81 extends in the indoor / outdoor direction below the existing upper frame 61, spanning between the guide rails 211, 212 of the existing upper frame 61 and the frame member 101. The indoor / outdoor extending plate portion 81 is fixed to the guide rails 611, 612 of the existing upper frame 61 with screws via two L-shaped mounting pieces 86.

[0028] As shown in Figures 10 and 11, the divided side gutter structure 82 is positioned on the outdoor side X1 of the indoor / outdoor extending plate portion 81. The divided side gutter structure 82 is formed in a concave shape that opens upward and is recessed downward. The divided side gutter structure 82 extends in the left-right direction (longitudinal direction, lateral direction) of the divided attachment portion 8. Both longitudinal ends of the divided side gutter structure 82 are formed to be open outward in the left-right direction.

[0029] Water that has entered the division-side gutter structural part 82 flows to both longitudinal ends of the division-side gutter structural part 82, is discharged from the longitudinal ends that are open to the left and right, and flows into the interior of the vertical attachment frame 33 via the main body-side gutter structural part 310 located below. Water that has flowed into the interior of the vertical attachment frame 33 is received by the existing lower frame 62 at the bottom of the vertical attachment frame 33 and discharged to the outside. Thus, by providing the division-side gutter structural part 82, it is possible to improve drainage performance and water-stopping performance.

[0030] As shown in Fig. 10, the outdoor vertically extending plate portion 83 is formed in a plate shape that includes the outdoor side X1 end portion of the dividing side horizontal gutter structural portion 82 and extends downward from the outdoor side X1 end portion of the dividing side horizontal gutter structural portion 82. In this embodiment, the outdoor vertically extending plate portion 83 has a width in the vertical direction and extends in the left-right direction. The outdoor vertically extending plate portion 83 is located on the outdoor side X1, extends in the view direction, and is formed to face the front of the outdoor side X1.

[0031] A pair of engaging protrusions 831 arranged spaced apart from one another in the vertical direction are formed on the lower side of the outdoor X1 surface of the outdoor vertically extending plate portion 83. A pair of engaging protrusions 511 of the outdoor decorative cover 51 engages with and is attached to the pair of engaging protrusions 831.

[0032] The outdoor upper extending plate portion 84 is formed in a plate shape extending upward from the upper end of the outdoor vertical extending plate portion 83. In this embodiment, the outdoor upper extending plate portion 84 has a width in the vertical direction and extends in the left-right direction. The outdoor upper extending plate portion 84 is disposed on the outdoor side X1 of the existing upper frame 61, extends in the view direction, and is formed to face the front of the outdoor side X1.

[0033] In this embodiment, the outdoor vertical extending plate portion 83 is not provided on the attachment frame main body 3, but on the divided attachment portion 8. For example, if the outdoor vertical extending plate portion 83 were provided on the attachment frame without providing the divided attachment portion 8, when the attachment frame is attached to the four outer peripheries of the new frame 2 and is assembled to the existing frame 6 from the indoor side X2, the outdoor vertical extending plate portion 83 would come into contact with the existing frame 6.

[0034] Therefore, in order to temporarily avoid the existing frame 6, it becomes necessary to insert the new frame, with the attachment frame attached to its outer periphery, into the opening of the existing frame 6 while tilting it from the indoor side X2, and once it has been extended to the outdoor side X1, it must then be pulled towards the existing frame 6 and attached to the existing frame. However, for example, if a grille, shutter, etc. is provided on the outdoor side X1, once the new frame is extended to the outdoor side X1, it may hit the grille, shutter, etc. provided on the outdoor side X1.

[0035] In contrast to this, in the present disclosure, the attachment frame 30 is divided into an attachment frame main body 3 and a divided attachment section 8. An outdoor vertical extension plate section 83 is provided on the divided attachment section 8, and the divided attachment section 8 is first attached to the existing frame 6, and then the new frame 2 with the attachment frame main body 3 attached is attached to the inner periphery of the existing frame 6. This allows the new frame 2 with the attachment frame main body 3 attached to its outer periphery to be easily attached from the indoor side X2 while tilting it and inserting it through an opening in the existing frame 6 from the indoor side X2, without first extending it to the outdoor side X1.

[0036] 8 and 9, the attachment frame body 3 is configured by an upper attachment frame 31, a lower attachment frame 32, and a pair of vertical attachment frames 33 arranged around all four sides to form a rectangle. The upper attachment frame 31, the lower attachment frame 32, and the left and right vertical attachment frames 33 are each made of, for example, aluminum material.

[0037] The upper attachment frame 31 is disposed at the top of the attachment frame main body 3 and extends in the left-right direction (horizontal direction). The lower attachment frame 32 is disposed at the bottom side of the attachment frame main body 3 and extends in the left-right direction (horizontal direction). The vertical attachment frame 33 is disposed at the left-right end side of the attachment frame main body 3 and extends in the up-down direction.

[0038] As shown in Fig. 8, the attachment frame body 3 has a vertically-attached structure in which the longitudinal ends of the vertical attachment frame 33 are arranged outside the longitudinal ends of the upper attachment frame 31 and the lower attachment frame 32. As shown in Fig. 9, the longitudinal ends of the upper attachment frame 31, the lower attachment frame 32, and the pair of vertical attachment frames 33 are fixed together with screws 34, with the longitudinal ends of the vertical attachment frame 33 arranged outside the longitudinal ends of the upper attachment frame 31 and the lower attachment frame 32.

[0039] As shown in FIG. 10, the attachment upper frame 31 has an attachment upper frame hollow portion 312, a main body side horizontal gutter structure portion 310, and an indoor side horizontal extension plate 314 (extension plate).

[0040] The attachment upper frame hollow section 312 and the main body side horizontal gutter structure section 310 are arranged side by side in the indoor / outdoor direction. The attachment upper frame hollow section 312 is arranged on the indoor side X2, and the main body side horizontal gutter structure section 310 is arranged on the outdoor side X1.

[0041] As shown in FIG. 10, the attachment upper frame hollow portion 312 is formed in a hollow shape of a long and narrow rectangle extending in the indoor and outdoor directions.

[0042] As shown in Figures 10 and 11, the main body-side gutter structure 310 is formed on the outdoor side X1 of the attachment upper frame hollow portion 312, at the top of the attachment upper frame 31. As shown in Figure 11, the main body-side gutter structure 310 is formed in a concave shape that opens upward and is recessed downward. The main body-side gutter structure 310 extends in the left-right direction (longitudinal direction, lateral direction) of the attachment upper frame 31. Both longitudinal ends of the main body-side gutter structure 310 are formed so as to be open outward in the left-right direction. The main body-side gutter structure 310 is positioned below the division-side gutter structure 82.

[0043] Water that has entered the main body side gutter structure 310 flows to both longitudinal ends of the upper attachment frame 31, passes through the longitudinal ends that are open outward in the left and right directions, passes through the cutouts 331 (see Figure 11) in the vertical attachment frame 33, and flows into the interior of the vertical attachment frame 33. The water that has flowed into the interior of the vertical attachment frame 33 is received by the existing lower frame 62 at the lower side of the vertical attachment frame 33 and is then discharged to the outside. Thus, by providing the main body side gutter structure 310, it is possible to improve drainage performance and water stopping performance.

[0044] Furthermore, because the main body-side gutter structural part 310 is positioned below the division-side gutter structural part 82, water discharged from the longitudinal end of the division-side gutter structural part 82 flows into the interior of the vertical attachment frame 33 via the main body-side gutter structural part 310 positioned below. Therefore, by positioning the main body-side gutter structural part 310 below the division-side gutter structural part 82, a double gutter structure is provided, further improving drainage performance.

[0045] As shown in Figure 10, the indoor-side horizontal extension plate 314 extends horizontally on the indoor-side X2 from the indoor-side X2 end of the upper end of the attachment upper frame hollow portion 312. When fixing the attachment frame main body 3 to the building 100 (skeleton), screws 36 are disposed to pass through the indoor-side horizontal extension plate 314. The screws 36 fix the indoor-side horizontal extension plate 314 of the attachment upper frame 31 to the building 100 (skeleton).

[0046] As a result, the indoor-side horizontal extension plate 314 of the attachment upper frame 31 is fixed to the building 100 (skeleton) by the screws 36. If a gap is formed between the indoor-side horizontal extension plate 314 of the attachment upper frame 31 and the building 100 (skeleton), a spacer member 37 is arranged. The spacer member 37 is made up of multiple sheets. An example of the spacer member 37 is a thin plate-like member made of a resin material or the like.

[0047] 2 and 3, the attachment lower frame 32 and the left and right vertical attachment frames 33 other than the attachment upper frame 31 are each fixed to the building 100 (skeleton) with screws 36. If gaps are formed between the attachment lower frame 32 and the left and right vertical attachment frames 33 and the frame member 101, spacer members 37 are disposed between the attachment lower frame 32 and the left and right vertical attachment frames 33 and the frame member 101.

[0048] As shown in Figure 3, the left and right vertical attachment frames 33 do not have extension plate portions that extend out in the viewing direction toward the building 100 side, so that the vertical attachment frames 33 do not collide with the existing frame 6 when attaching them to the outside X1.

[0049] 2 and 3, the renovated fitting 1 has an airtight structure 70. The airtight structure 70 is configured to connect the existing frame 6 side and the new frame 2 side with airtight tape (existing frame side airtight tape 71, connecting airtight tape 72) to the attachment frame 30 attached to the new frame 2. The airtight structure 70 is arranged to connect the existing frame 6 and the attachment frame 30 attached to the new frame 2 in order to improve the airtight performance between the existing frame 6 and the new frame 2.

[0050] By having an airtight structure 70 that is configured to connect the existing frame 6 side and the new frame 2 side with airtight tape (existing frame side airtight tape 71, connecting airtight tape 72), an airtight line can be secured in the area where a portion of the existing frame side airtight tape 71 and a portion of the connecting airtight tape 72 overlap, thereby ensuring airtight performance.

[0051] 2 and 3, the indoor-side decorative members 41, 42, 43 are attached to the resin angle members 213, 223, 233 of the new frame 2 on the indoor side X2. The boundary between the indoor-side decorative members 41, 42, 43 and the inner peripheral surface of the frame member 101 is shielded by a trim member 45 with an L-shaped cross section that is fixed to the building 100 (frame).

[0052] As shown in Figs. 4 and 5, the exterior decorative covers 51, 52, 53 are attached to the surfaces of the exterior side X1 of the upper attachment frame 31, the lower attachment frame 32, and the vertical attachment frame 33, respectively.

[0053] Next, we will explain the procedure for constructing the remodeled fitting 1. When constructing the remodeled fitting 1, the attachment frame main body 3 is assembled in advance to the outer periphery of the newly constructed frame 2 that has been assembled around all four sides.

[0054] When constructing the remodeled fitting 1, as shown in Fig. 12A, first, the divided attachment part 8 is fixed to the lower part of the existing upper frame 61. Specifically, the divided attachment part 8 is fixed to guide rails 611, 612 for the existing shoji screen, which are provided on the existing upper frame 61 and stand upright facing downward.

[0055] Next, as shown in Figure 12B, the new frame 2 with the attachment frame main body 3 attached is tilted so that the lower end is positioned on the outside X1 rather than the upper end, and is fitted into the opening of the existing frame 6 from the inside X2 of the existing frame 6, and then rotated around the lower end to assemble it to the existing frame 6 as shown in Figure 12C.

[0056] Here, the upper attachment frame 31 and the vertical attachment frame 33 of the attachment frame main body 3 do not have an extension plate portion that protrudes in the view direction toward the building 100 on the outside side X1. Therefore, since the upper attachment frame 31 and the vertical attachment frame 33 of the attachment frame main body 3 do not have an extension plate portion, the upper attachment frame 31 and the vertical attachment frame 33 of the attachment frame main body 3 do not collide with the existing frame 6, so it is not necessary to once move the new frame 2 with the attached attachment frame main body 3 to the outside side X1 of the existing frame 6 and pull it toward the existing frame 6 to attach it to the existing frame 6. In other words, the new frame 2 with the attached attachment frame main body 3 can be easily attached to the existing frame 6 from the inside side X2. This improves the workability of the renovation fitting 1.

[0057] 12C, the indoor-side horizontal extension plate 314 of the attachment upper frame 31 is fixed to the building 100 (skeleton) with screws 36. Spacer members 37 are placed in locations where gaps are formed between the indoor-side horizontal extension plate 314 of the attachment upper frame 31 and the building 100 (skeleton).

[0058] 12D, on the outside side X1, the outside decorative cover 51 is attached to the outside side X1 of the divided attachment part 8, and the outside decorative covers 52 and 53 are attached to the outside side X1 surfaces of the attachment lower frame 32 and the attachment vertical frame 33, respectively. Then, on the inside side X2, the inside decorative members 41, 42, and 43 are attached to the resin angle members 213, 223, and 233 of the new frame 2, respectively. An L-shaped parting material 45 is attached to the boundary between the inside decorative members 41, 42, and 43 and the inner surface of the frame member 101.

[0059] According to this embodiment, the following effects are achieved: The renovated fitting 1 of this embodiment is attached to an existing frame 6 provided at an opening in the building 100 and comprises a new frame 2 configured by assembling all four sides, and an attachment frame 30 arranged between the new frame 2 and the existing frame 6, and the attachment frame 30 has an attachment frame main body 3 attached to the outer periphery of the new frame 2 by assembling all four sides, and a divided attachment part 8 arranged above the attachment frame main body 3 and therefore arranged between the existing upper frame 61 of the existing frame 6 and the attachment frame main body 3.

[0060] This allows the split attachment parts 8 to be attached to the existing frame 6, and then the new frame 2 with the attached attachment frame body 3 can be easily attached to the inner periphery of the existing frame 6 from the indoor side X2, improving workability. Also, since the split attachment parts 8 are provided on the top of the attachment frame 30, water-stopping performance can be improved. Therefore, workability can be improved and water-stopping performance can be improved.

[0061] In this embodiment, the divided attachment parts 8 are fixed to the existing upper frame 61. As a result, after the divided attachment parts 8 are attached to the existing upper frame 61, the new frame 2 with the attached attachment frame body 3 can be easily attached to the inner periphery of the existing frame 6 from the indoor side X2.

[0062] Furthermore, in this embodiment, the divided attachment parts 8 are fixed to guide rails 611, 612 for existing shoji screens that are provided on the existing upper frame 61 and stand upright facing downward. As a result, the divided attachment parts 8 can be fixed to the existing upper frame 61 simply by fixing them to the guide rails 611, 612 for the existing shoji screens, and therefore the divided attachment parts 8 can be fixed to the existing upper frame 61 with a simple configuration.

[0063] In this embodiment, the divided attachment part 8 has a divided side gutter structure part 82 that opens upward and extends laterally. This improves the drainage performance of the divided attachment part 8 and improves the water-stopping performance.

[0064] Furthermore, in this embodiment, the attachment upper frame 31 has a main body-side gutter structure 310 that opens upward and extends laterally. This improves the drainage performance of the attachment upper frame 31, thereby improving water-stopping performance. Furthermore, in this embodiment, the main body-side gutter structure 310 is disposed below the division-side gutter structure 82. As a result, water discharged from the longitudinal end of the division-side gutter structure 82 flows into the interior of the attachment vertical frame 33 via the main body-side gutter structure 310 disposed below. Therefore, by disposing the main body-side gutter structure 310 below the division-side gutter structure 82, a double gutter structure is provided, further improving drainage performance.

[0065] Furthermore, in this embodiment, the split attachment section 8 has an outdoor upward extending plate section 84 that extends outward in the viewing direction on the outdoor side X1. As a result, because the split attachment section 8 has the outdoor upward extending plate section 84, the upper attachment frame 31 does not have an outdoor upward extending plate section. Therefore, when attaching the new frame 2 with the attachment frame body 3 attached to it from the indoor side X2 to the inner periphery of the existing frame 6, there is no outdoor upward extending plate section that gets in the way, so the new frame 2 with the attachment frame body 3 attached can be easily attached to the existing frame 6 from the indoor side X2. This further improves workability.

[0066] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.
