Embodiments of the present invention will be described below based on the drawings. 1 and 2 show a first embodiment of the refurbished sash of the present invention. This renovated sash is applied to double-sliding windows, and includes a renovated frame 3 that is installed from the outdoor side into the opening 26 to which the existing frame 4 is attached and fixed to the frame 5, and a renovated frame 3 that is attached to the indoor side of the renovated frame 3. It includes a resin picture frame 27, an outer shoji 28, an inner shoji 29, and a screen door 30 that are slidably housed along the upper and lower horizontal frames of the reform frame 3.

The existing frame 4 is a sash frame without angles for sliding windows, and as shown in Figures 1 and 2, the upper frame 31, lower frame 32, and left and right vertical frames 33, 33 made of aluminum are used as a frame. It is constructed as such and is attached to the frame 5 in a so-called semi-external state. An existing wooden picture frame 34 is provided on the indoor side of the existing frame 4.

As shown in FIGS. 1 to 3, the renovation frame 3 is composed of a new frame 1 and an outer peripheral frame 2 surrounding the new frame 1.
The new frame 1 is constructed by framing an upper frame 35, a lower frame 36, and left and right vertical frames 37, 37 made of aluminum shapes around the four sides. The upper frame 35 and the lower frame 36 are thermally insulated by providing a heat insulating bridge 38 at an intermediate portion in the viewing direction. Furthermore, the newly installed frame 1 is provided with a resin angle 39 on the indoor side to prevent dew condensation on the indoor side.
As shown in FIG. 7, this new frame 1 is made by breaking off the fins 40 for fixing the frame of a general semi-external sash frame.

As shown in FIG. 8, the new frame 1 is provided with a metal reinforcing plate 25 in contact with the outer peripheral side surfaces of the left and right vertical frames 37, 37. The reinforcing plate 25 is arranged at two locations on the upper and lower sides of the outer circumferential side of the vertical frame 37 on the sides of the upper frame 35 and the lower frame 36, and screws 41 are inserted through the reinforcing plate 25 and the vertical frame 37 from the outer circumferential side. By screwing into the tapping holes 42 of the upper frame 35 and the lower frame 36, the reinforcing plate 25 and the vertical frame 37 are fastened together to the upper frame 35 and the lower frame 36. A sheet-like sealer 43 is interposed between the longitudinal end surfaces of the upper frame 35 and the lower frame 36 and the inner peripheral side surface of the vertical frame 37. The reinforcing plate 25 has its outdoor end abutted against a piece 44 that projects toward the outer circumferential side of the vertical frame 37.

By providing the reinforcing plate 25 on the outer periphery of the vertical frame 37 in this way and fastening the reinforcing plate 25 and the vertical frame 37 together to the horizontal frames (upper frame, lower frame) 35, 36 with screws 41, the shoji 28, 29 This prevents the vertical frame 37 from being deformed so as to expand toward the outer periphery when, for example, the vertical frame 37 is forcefully closed, thereby maintaining watertightness. By abutting the outdoor end of the reinforcing plate 25 against the piece 44 protruding toward the outer peripheral side of the vertical frame 37, the effect of preventing deformation of the vertical frame 37 is enhanced. Note that the reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 37 of the newly installed frame 1 in the same manner as in the second, fourth, and fifth embodiments described later.

As shown in FIGS. 1 to 4, the outer peripheral frame 2 is constructed by framing an upper frame 45, a lower frame 46, and left and right vertical frames 47, 47 made of aluminum sections around the four sides. More specifically, the longitudinal end surfaces of the upper frame 45 and the lower frame 46 are abutted against the inner circumferential surfaces of the vertical frames 47 and 47 via the sealing material 56 (see FIGS. 2 and 3), and the vertical frames are pressed from the side. The frame is formed by screwing the inserted screws 103 (see FIGS. 3 and 4) into the tapping holes 48 of the upper and lower frames 45 and 46.
As shown in FIGS. 1 and 2, the upper frame 45, the lower frame 46, and the left and right vertical frames 47 are removably attached to the main member 49 extending in the viewing direction and the outdoor end of the main member 49, and It is composed of two members, a cover piece 50 extending toward the side. Each cover piece 50 overlaps the outdoor side of the outdoor side wall of the existing frame. The main member 49 is provided with an extension part 51 that extends indoors beyond the indoor walls of the new frame 1 and the existing frame 4, and the extension part 51 has screws for fixing the remodeled frame 3 to the frame 5. A hole 53 is provided through which the hole 52 is inserted. Further, the main member 49 is provided with positioning portions 54 at two locations, one on the outdoor side and one on the indoor side, and each positioning portion 54 is engaged with the upper frame 35, lower frame 36, and vertical frame 37 of the new frame 1 from the outer peripheral side. This allows the upper frame 45, lower frame 46, and vertical frame 47 of the outer peripheral frame 2 to be positioned in the projection direction, and also allows the newly installed frame 1 and the outer peripheral frame 2 to be integrated. The cover piece 50 is provided with a plurality of breakable portions 55 at intervals in the inner and outer circumferential directions on the indoor side surface, and can be broken off at the breakable portions 55 as appropriate depending on the shape of the existing frame 4, etc. Dimensions can be changed.

As shown in FIGS. 1 and 2, airtight materials 57a, 57b, 57c, and 57d are continuously provided in the gap between the outer circumferential side surface of the new frame 1 and the inner circumferential side surface of the outer circumferential frame 2. These airtight members 57a, 57b, 57c, and 57d are provided at positions where the fins 40 of the newly installed frame 1 are broken off.
A sealing material 56 is provided on the vertical frame 47 of the outer peripheral frame 2 at the joints with the end faces of the horizontal frames (upper frame, lower frame) 45 and 46, and extends along the horizontal frames 45 and 46 of the outer peripheral frame 2. The longitudinal ends of the horizontal airtight members 57a, 57b and the vertical airtight members 57c, 57d extending along the vertical frames 47, 47 of the outer peripheral frame 2 are in contact with the sealing material 56, and the horizontal airtight members 57a, 57b are in contact with the sealing material 56 via the sealing material 56. 57a, 57b and vertical airtight members 57c, 57d are continuous. This prevents rainwater from entering the room through the gap between the newly installed frame 1 and the outer peripheral frame 2.
In addition, the gap between the cover piece 50 of the upper frame 45 of the outer peripheral frame 2 and the outdoor wall of the upper frame 31 of the existing frame 4, the cover pieces 50, 50 of the vertical frames 47, 47 of the outer peripheral frame 2, and the vertical frame of the existing frame 4. Airtight materials 58a and 58b are also continuously provided in the gaps between the walls 33 and 33 on the outdoor side. This prevents rainwater from entering the gap between the reform frame 3 and the existing frame 4.

As shown in FIGS. 1 and 2, on the inner circumferential side of the existing frame 34 on the indoor side of the existing frame 4, mounting auxiliary materials 6, which serve as a base for fixing the remodeling frame 3 to the frame 5, are provided around the four sides. . The mounting auxiliary member 6 is made of an aluminum profile, and is formed into a U-shape in cross section by the facing walls 59a, 59b on the outdoor side and the indoor side and the facing wall 60. A plurality of breakable portions 61 are provided on the outdoor side and indoor side facing walls 59a, 59b at intervals in the inner and outer circumferential directions. The mounting auxiliary material 6 is adjusted by appropriately breaking off the facing walls 59a and 59b at the breakable portion 61, and adjusting the facing dimensions so that the position of the inner circumferential side surface of the facing wall 60 protrudes most toward the inner circumferential side of the existing frame 4. It is arranged to be located at approximately the same position in the inner and outer circumferential directions as the portion 62. In addition, in FIGS. 1 and 2, it appears that the facing walls 59a and 59b are interfering with the existing picture frame 34, but in reality, they are broken off at the breakable portion 61, and the portions that interfere with the existing picture frame 34 are eliminated.
Each mounting auxiliary material 6 is placed so that the outdoor facing wall 59a is in contact with the indoor wall of the existing frame 4, so that the indoor end of the mounting auxiliary material 6 is positioned at a predetermined distance from the outdoor end of the existing frame 4. The mounting aid 6 is positioned in the projection direction so that the dimension A (specifically, 110 mm) is obtained. The mounting aid 6 is fixed to the frame 5 with screws 63 inserted into the expected wall 60 from the inner circumferential side.

As shown in FIGS. 1 and 2, the remodeling frame 3 is positioned in the prospective direction so that the indoor end 64 of the outer peripheral frame 2 coincides with the indoor end of the mounting auxiliary material 6, and is extended at the location of the mounting auxiliary material 6. It is fixed to the frame 5 with screws 52 inserted into the protrusion 51 from the inner circumferential side. A pet tree 65 is interposed between the outer peripheral frame 2 and the attachment auxiliary material 6 as necessary.
In this renovated sash, the installation auxiliary material 6 is installed in such a state that it is in contact with the indoor wall of the existing frame 4, and the indoor end 64 of the remodeled frame 3 (the outer peripheral frame 2) is attached to the installation auxiliary material 6. By positioning the renovation frame 3 in the expected direction so as to match the indoor end, the renovation frame 3 is naturally placed at an appropriate position in the expected direction, and the cover piece 50 of the renovation frame 3 and the exterior of the existing frame 4 are aligned in advance. Airtight materials 58a and 58b provided on one side wall are in close contact with the other side wall, and water is stopped between the reform frame 3 and the existing frame 4 on the outdoor side.

Furthermore, as shown in FIGS. 1 and 2, this renovated sash has an existing frame-side waterproof tape 7 attached across the existing frame 4 and the mounting aid 6, and the extension wall 60 of the mounting aid 6 and the indoor side view. A waterproof tape 66 for hiding screws is attached across the attached wall 59b, and a waterproof tape 8 on the remodeling frame side is provided spanning the remodeling frame 3 and the attachment auxiliary material 6. The waterproof tape 66 for hiding screws hides the screws 63 that attach the mounting auxiliary material 6 to the frame 5, and the waterproof tape 8 on the reform frame side hides the screws 52 that attach the reform frame 3 to the frame 5. . Each of the waterproof tapes 7, 8, and 66 is attached to the existing frame 4 and the remodeled frame 3 by continuously pasting them along the circumferential direction using commercially available waterproof tapes having appropriate widths.

In this way, this renovated sash has the existing frame side waterproof tape 7 attached across the existing frame 4 and the installation aid 6, and the renovation frame side waterproof tape 8 attached across the installation aid 6 and the renovation frame 3. Thus, even if rainwater should enter between the remodeling frame 3 and the existing frame 4 from the outdoor side, it can be prevented from penetrating into the indoor side. By providing the mounting aid 6 on the periphery of the opening 26 and pasting the waterproof tapes 7 and 8 on the mounting aid 6, a smooth surface to which the waterproof tapes 7 and 8 are attached can be ensured, and the waterproof tapes 7, 8 can be applied neatly, so it has high water-stop properties. Moreover, rather than applying one piece of waterproof tape across the existing frame 4 and reform frame 3, it is more efficient to apply it separately to the existing frame side waterproof tape 7 and the reform frame side waterproof tape 8. Furthermore, since the screws 63 for attaching the mounting auxiliary material 6 to the frame body 5 are hidden by the screw-concealing waterproof tape 66, rainwater can be prevented from entering the frame body 5 through the holes of the screws 63.

As shown in FIGS. 1, 2, and 4, reinforcing members 24 made of metal plates are placed at intervals in the longitudinal direction of the frames 67 and 68 on the outer peripheral sides of the vertical frame 67 and the upper frame 68 of the reform frame 3. A plurality of them (three in FIG. 4) are provided. The reinforcing material 24 is provided over almost the entire width of the remodeling frame 3 in the expected direction, and is attached to the vertical frame 67 and the upper frame 68 by screws 69 from the outer circumferential side. A hole 70 into which a screw 52 for fixing the reform frame 3 to the frame 5 is inserted is provided at the indoor end of the reinforcing member 24 in alignment with the position of the hole 53 in the reform frame 3. The reform frame 3 and reinforcing material 24 are fixed together to the frame 5 with screws 52 on the indoor side.

In this renovated sash, the reinforcing material 24 is provided on the outer periphery of the renovated frame 3, and the renovated frame 3 and the reinforcing material 24 are both fixed to the frame 5 on the indoor side, so that the renovated frame 3 can be attached to the indoor side. Even if it is fixed to the frame 5 in a cantilevered manner at one end portion, the reform frame 3 can be prevented from falling toward the inner circumference or the outer circumference using the portion fixed to the frame 5 as a fulcrum. Note that the same points regarding the reinforcing material 24 apply to the second to fifth embodiments described later.

Furthermore, as shown in FIG. 1, in this renovated sash, a gap adjustment part 72 is arranged at the outdoor end of the gap between the upper surface of the lower frame 32 of the existing frame 4 and the lower surface of the lower frame 71 of the remodeled frame 3. be. The height of the gap adjustment component 72 is adjustable according to the size of the gap. The cover piece 50 of the lower frame 71 of the remodeling frame 3 is of a fitting type so that it can be easily attached and removed from the outdoor side, and the gap adjustment component 72 is hidden by the cover piece 50.
In this way, the gap adjustment component 72 is provided in the gap between the upper surface of the lower frame 32 of the existing frame 4 and the lower surface of the lower frame 71 of the remodeling frame 3, so that the lower frame 71 of the remodeling frame 3 hangs down on the outdoor side. This can prevent deformation.

The resin picture frame 27 is made of an extruded resin material, and as shown in FIGS. 1 and 2, it has a projected surface portion 73 that extends indoors continuously from the resin angle 39 of the newly installed frame 1, and an indoor end of the projected surface portion 73. It has a finding surface part 74 extending toward the outer circumferential side from the part. The resin angle 39 of the newly installed frame 1 is screwed to the prospective surface portion 73 from the inner peripheral side with a screw 75. The indexing surface part 74 is provided with a plurality of breakable parts 76 at intervals in the inner and outer circumferential directions on the outdoor side surface, and the indexing surface part 74 By appropriately breaking off the material at the breakable portion 76, the dimensions can be adjusted. An angled decorative material 77 is attached to the existing picture frame 34, and the gap between the tip of the facing surface part 74 and the existing picture frame 34 is hidden by the decorative material 77.
By attaching the resin frame 27 in this way, the present renovated sash has a good design because the resin frame 27 hides the existing frame 4, the mounting auxiliary material 6, and the remodeled frame 3. Furthermore, the resin picture frame 27 is formed into an L-shaped cross section by a facing surface portion 73 that is continuous with the resin angle 39 of the new frame 1 and a facing surface portion 74 that extends outward from the indoor end of the facing surface portion 73. , the interior design can be further improved.

Next, we will explain the construction procedure for this renovated sash. First, as shown in FIGS. 5 and 6, the attachment auxiliary material 6 is attached to the indoor side of the existing frame 4 with screws 63. At that time, the mounting auxiliary material 6 is made by appropriately breaking off the facing walls 59a and 59b at the breakable portion 61, so that the part 62 that protrudes most toward the inner circumference of the existing frame 4 and the facing wall 60 of the mounting auxiliary material 6 are separated. After adjusting the facing dimensions so that they are approximately on the same plane in the projected direction, the facing wall 59a on the outdoor side of the mounting auxiliary material 6 is brought into contact with the indoor wall of the existing frame 4, and positioned in the projected direction for installation.
Next, an existing frame-side waterproof tape 7 is attached spanning the existing frame 4 and the mounting auxiliary material 6, and a screw-hiding waterproof tape 66 is attached from the expected wall 60 of the mounting auxiliary material 6 to the existing frame 34.
Next, the reform frame 3 is assembled. The remodeling frame 3 is assembled by placing the upper frame 45, the lower frame 46, and the left and right vertical frames 47, 47 of the outer frame 2 over the new frame 1, which has been framed in advance, from the outer periphery while positioning them with the positioning parts 54. The end surfaces of the frames 45, 46 are abutted against the inner circumferential surfaces of the vertical frames 47, 47 via the sealing material 56, and the screws 103 inserted through the vertical frames 47 from the side are screwed into the tapping holes 48 of the upper and lower frames 45, 46. Frame it with. After that, the reinforcing material 24 is attached to the outer peripheral side surfaces of the vertical frames 47, 47 and the upper frame 45. Note that the remodeling frame 3 may be assembled at the construction site of the remodeled sash, but it can also be assembled at a factory and transported to the construction site.
Next, as shown in FIGS. 5 and 6, the reform frame 3, which is made by integrating the new frame 1 and the outer peripheral frame 2 as described above, is fitted from the outdoor side into the opening 26 to which the existing frame 4 is attached. The reform frame 3 is positioned in the expected direction so that the indoor end (indoor end of the outer peripheral frame 2) 64 coincides with the indoor end of the mounting auxiliary material 6. Additionally, the cover piece 50 of the lower frame 71 of the remodeling frame 3 is removed once, and the height of the gap adjustment component 72 is adjusted to match the size of the gap between the lower frame 32 of the existing frame 4 and the lower frame 71 of the remodeling frame 3. After that, the cover piece 50 is attached. Thereafter, the reform frame 3 is fixed to the frame from the inner circumferential side on the indoor side with screws 52. Thereafter, the renovation frame side waterproof tape 8 is attached across the installation auxiliary material 6 and the renovation frame 3.
After that, the resin picture frame 27 is attached from the indoor side.

25 and 26 show a modification of the renovated sash of the first embodiment, which is applied to a bathroom window. Hereinafter, the differences from a normal living room window (see FIGS. 1 and 2) will be explained.
First, the waterproof tape 66 for hiding screws is extended toward the outer periphery, and its outer periphery end is adhered to the frame (frame 34). Next, a renovation frame side waterproof tape 104 is continuously provided four times over the indoor side of the new frame 1 and the indoor side of the outer peripheral frame 2. Furthermore, instead of hiding the gap between the tip of the marking piece 74 of the resin picture frame 27 and the existing picture frame 34 with the angled decorative material 77, it is sealed with a sealing material 105.
By doing so, the renovated sash of this embodiment can prevent water from entering the frame from the bathroom side when water is applied from the bathroom side.

As described above, this renovated sash is constructed by surrounding the new frame 1 with the outer frame 2, and the new frame 1 and the outer frame 2 are integrated into the opening to which the existing frame 4 is attached. 26 from the outdoor side and fixing the outer circumferential frame 2 to the frame 5, it is not necessary to process the existing frame 4 or attach members to the inner circumferential side of the existing frame 4, resulting in good workability. By fixing the outer peripheral frame 2 to the frame 5 on the indoor side, workability is further improved.

FIG. 9 shows a second embodiment of the refurbished sash of the present invention. This renovated sash is applied to a double-sliding window like the first embodiment, except that the lower frame 32 of the existing frame 4 is provided with an angle 78. The mounting auxiliary member 79 on the lower frame 32 side is a substantially band-shaped component made of an aluminum profile. This attachment aid 79 is provided with a breakable portion 80 on the lower surface on the outdoor side, and the expected dimensions can be adjusted by breaking it off at the breakable portion 80. This installation auxiliary material 79 is positioned in the expected direction so that the indoor end is a certain distance A (specifically, 110 mm) from the outdoor end of the existing frame 4, and the outdoor end is placed under the existing frame 4. It is stacked on the angle 78 of the frame 32, and the indoor side part is fixed to the frame 5 with screws 63.

As shown in FIGS. 10(a) and 10(b), the mounting auxiliary material 79 is stored in the recess 83, and the main jig 81 is brought into contact with the abutting part 82 against the outdoor end of the lower frame 32 of the existing frame 4. By applying the mounting aid 79 to the lower frame 32 of the existing frame 4 from above, the mounting auxiliary material 79 is positioned so that its indoor end is a constant dimension A from the outdoor end of the lower frame 32 of the existing frame 4. .

In this way, the mounting aid 79 is positioned so that its indoor end is a certain distance A from the outdoor end of the existing frame 4 and fixed to the frame 5, and the mounting aid 79 is connected to the indoor end 64 of the remodeled frame 3. By positioning the remodeling frame 3 and fixing it to the frame 5 so that the indoor side edges of the frames 79 and 79 coincide with each other, the cover piece 50 of the remodeling frame 3 and the outdoor side wall of the existing frame 4 can be connected, similarly to the first embodiment. The gap is water-tight with airtight materials 58a and 58b.

FIG. 11 shows a modification of the renovated sash of the second embodiment, in which the expected dimension B of the existing frame 4 is smaller than that of FIG. 9 (specifically, the estimated dimension B of the existing frame 4 of FIG. The estimated dimension B is 70 mm, and the estimated dimension B of the existing frame 4 in FIG. 11 is 60 mm). In this case as well, the mounting auxiliary material 79 is attached so that its indoor end is a certain distance A (specifically 110 mm) from the outdoor end of the existing frame 4, and The mounting auxiliary material 79 moves toward the indoor side by the amount (10 mm) that the expected dimension B becomes smaller.
On the other hand, if the estimated dimension B of the existing frame 4 is larger than that shown in FIG. 9, the mounting auxiliary member 79 will be moved to the outdoor side by that amount. When the mounting aid 79 is moved to the outdoor side, if the outdoor end of the mounting aid 79 protrudes beyond the indoor wall of the existing frame 4, it can be broken off at the breakable portion 80 and installed. The dimensions of the auxiliary material 79 are reduced.

12 and 13 show a third embodiment of the refurbished sash of the present invention. The renovated sash of this embodiment has a substantially L-shaped cross section in which the upper frame 45 and vertical frame 47 of the outer peripheral frame 2 are integrally formed with a portion 84 extending in the forward direction and a cover piece 50 extending toward the outer peripheral side on the outdoor side. It has become a material. In this way, by making the upper frame 45 and the vertical frame 47 of the outer peripheral frame 2 integrally molded, the number of members can be reduced and the time and labor required for assembling the reform frame 3 can be saved.

Further, in the renovated sash of this embodiment, as shown in FIG. 14, a reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 47 of the outer peripheral frame 2. That is, the reinforcing plates 25 are disposed at two locations on the upper and lower sides of the outer circumferential side of the vertical frame 47 of the outer circumferential frame 2, at positions on the sides of the upper frame 45 and the lower frame 46 of the outer circumferential frame 2, and the reinforcing plates 25 are arranged from the outer circumferential side.
