[0007] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figures 1 to 5 show a first embodiment of a remodeled sash of the present invention. This remodeled sash is applied to a double sliding window of the French style, and as shown in Figures 1 and 2, it comprises a remodeled frame 1 fitted from the outside into an opening 6 to which an existing frame 4 is attached and fixed to a frame 7, a resin frame 8 attached to the inside of the remodeled frame 1, and an outer shoji screen 9, an inner shoji screen 10, and a screen door 11 fitted slidably along the upper and lower horizontal frames of the remodeled frame 1.

[0008] The existing frame 4 is a sash frame for a sliding window, and as shown in Figures 1 and 2, is composed of an upper frame 12, a lower frame 13, and left and right vertical frames 14, 14 made of aluminum extrusions, and is attached to the main body 7 in a so-called semi-external state. An existing wooden frame (indoor component) 15 is provided on the indoor side of the upper frame 12 and left and right vertical frames 14, 14 of the existing frame 4. The lower frame 13 of the existing frame 4 has an angle 16, and a floorboard (indoor component) 17 is provided on the indoor side of the lower frame 13.

[0009] As shown in Figures 1 and 2, the reform frame 1 is composed of a new frame 18 and an outer frame 19 that surrounds the new frame 18. The new frame 18 is made up of an upper frame 20, a lower frame 21, and left and right vertical frames 22, 22, all of which are made of aluminum extrusions. The upper frame 20 and the lower frame 21 are insulated by an insulating bridge 23 in the middle in the prospective direction. The new frame 18 also has a resin angle 24 on the indoor side to prevent condensation on the indoor side. This new frame 18 is made by breaking off the fins used to secure the frame to the semi-external sash frame of a regular sash or general sash, which is not a reformed frame.

[0010] 1, 2, and 7, the outer peripheral frame 19 is formed by a framework of an upper frame 25, a lower frame 26, and left and right vertical frames 27, 27, all of which are made of aluminum extrusions. More specifically, the longitudinal end faces of the upper frame 25 and the lower frame 26 are abutted against the inner peripheral side surfaces of the vertical frames 27, 27 via sealing material 28 (see FIG. 7), and screws 29 (see FIG. 7) are inserted through the vertical frames 27, 27 from the side and screwed into tapping holes 30 (see FIG. 1) in the upper and lower frames 25, 26 to form the framework. As shown in Figures 1 and 2, the upper frame 25, lower frame 26, and left and right vertical frames 27, 27 are each composed of two members: a main member 31 extending in the prospective direction, and a cover piece 32 that is detachably attached to the outside end of the main member 31 and extends toward the outer periphery. Each cover piece 32 overlaps the outside of the outside wall of the existing frame 4, and the cover piece 32 hides the existing frame 4 so that it cannot be seen from the outside. The main member 31 has an extension portion 33 that extends further indoors than the indoor-side walls of the new frame 18 and the existing frame 4, and the extension portion 33 is fixed to the main body 7 with screws 34 from the inner periphery. The main member 31 also has a positioning portion 35 on the outdoor side, and by engaging the positioning portion 35 with the upper frame 20, lower frame 21, and vertical frames 22, 22 of the new frame 18 from the outer periphery, the upper frame 25, lower frame 26, and vertical frames 27, 27 of the outer periphery frame 19 can be positioned in the prospective direction, and the new frame 18 and the outer periphery frame 19 can be integrated. The cover piece 32 has a plurality of breakable sections 36 spaced apart in the inner and outer periphery on the indoor side, and the visible dimensions can be changed by breaking off the breakable sections 36 as appropriate according to the shape of the existing frame 4, etc.

[0011] 1 and 2, airtight material 37 is provided continuously around all four sides in the gap between the outer peripheral side surface of the new frame 18 and the inner peripheral side surface of the outer peripheral frame 19. This airtight material 37 is provided at the position where the fins for fixing the new frame 18 to the body were broken off. By providing airtight material 37 continuously around all four sides in the gap between the new frame 18 and the outer peripheral frame 19 in this way, rainwater is prevented from entering the room through the gap between the new frame 18 and the outer peripheral frame 19. In addition, airtight material 38 is continuously provided in the gap between the cover piece 32 of the upper frame 25 of the outer perimeter frame 19 and the outdoor wall of the upper frame 12 of the existing frame 4, and in the gap between the cover piece 32 of the vertical frames 27, 27 of the outer perimeter frame 19 and the outdoor wall of the vertical frames 14, 14 of the existing frame 4. This prevents rainwater from entering the gap between the reform frame 1 and the existing frame 4.

[0012] 1 and 4, an auxiliary mounting member (indoor member) 5 for adjusting the mounting position of the reform frame 1 in the inner and outer periphery directions is provided on the indoor side of the angle 16 of the bottom frame 13 of the existing frame 4. The auxiliary mounting member 5 is formed, for example, from a wooden board, and the upper surface of the auxiliary mounting member 5 is flush with the upper surface of the angle 16 of the bottom frame 13 of the existing frame 4. An outdoor waterproof tape 2a is provided across the outdoor side of the indoor wall 39 of the bottom frame 13 of the existing frame 4, the upper surface of the angle 16, and the upper surface of the auxiliary mounting member 5. In addition, an intermediate waterproof tape 2b is provided across the upper surface of the mounting support material 5 and the upper surface of the floorboard 17. The intermediate waterproof tape 2b has an outdoor portion 57 attached to the inner periphery of the outdoor waterproof tape 2a. Furthermore, an indoor waterproof tape 2c is provided spanning from the indoor side of the lower frame 26 of the reform frame 1 (peripheral frame 19) to the intermediate waterproof tape 2b. Each waterproof tape 2a, 2b, 2c is made of commercially available waterproof tape of an appropriate width and is attached along the length of the bottom frame 13 of the existing frame 4. Specifically, the exterior waterproof tape 2a, intermediate waterproof tape 2b, and interior waterproof tape 2c are basically 35 mm wide. However, the intermediate waterproof tape 2b and the interior waterproof tape 2c must be overlapped (by at least 10 mm), and if 35 mm is insufficient, a 50 mm wide tape is used (the same applies to the waterproof tapes 2a, 2b, 2c on the upper frame side and vertical frame side, described below). If the waterproof tapes 2b and 2c are wide and extend beyond the resin frame 8, the excess tape is cut off. However, the present invention is not limited to the above, and it is also possible to use a 35 mm or 50 mm wide tape for the outdoor waterproof tape 2a, and a 35 mm wide tape for the intermediate waterproof tape 2b and the indoor waterproof tape 2c.

[0013] As shown in Figure 1, an attachment support member 5 is also provided on the inner periphery of the existing frame 15, located on the indoor side of the upper frame 12 of the existing frame 4. An exterior waterproof tape 2a is provided between the exterior surface of the indoor wall 39 of the upper frame 12 of the existing frame 4 and the interior side of the attachment support member 5. An intermediate waterproof tape 2b is also provided between the interior side of the attachment support member 5 and the interior side of the existing frame 15. The exterior portion 57 of the intermediate waterproof tape 2b is attached to the exterior waterproof tape 2a. Furthermore, an interior waterproof tape 2c is provided from the interior side of the upper frame 25 of the renovation frame 1 (periphery frame 19) to the intermediate waterproof tape 2b. Each waterproof tape 2a, 2b, and 2c is attached along the longitudinal direction of the upper frame 12 of the existing frame 4. As shown in Figure 2, an attachment support member 5 is also provided on the inner periphery of the existing frame 15, located on the indoor side of the vertical frame 14 of the existing frame 4. An exterior waterproof tape 2a is provided between the exterior surface of the indoor wall 39 of the vertical frame 14 of the existing frame 4 and the interior side of the attachment support member 5. An intermediate waterproof tape 2b is also provided between the interior side of the attachment support member 5 and the interior side of the existing frame 15. The exterior portion 57 of the intermediate waterproof tape 2b is attached to the exterior waterproof tape 2a. Furthermore, an interior waterproof tape 2c is provided from the interior side of the vertical frame 27 of the renovation frame 1 (periphery frame 19) to the intermediate waterproof tape 2b. Each waterproof tape 2a, 2b, and 2c is attached along the longitudinal direction of the vertical frame 14 of the existing frame 4. The four outer waterproof tapes 2a, intermediate waterproof tapes 2b and inner waterproof tapes 2c are all provided at the same position in the prospective direction and are provided contiguously with one another so that there are no gaps between the ends.

[0014] In this renovated sash, the exterior waterproof tape 2a is provided from the interior side of the existing frame 4 to the mounting support material 5, the intermediate waterproof tape 2b is provided from the mounting support material 5 to the floorboard 17 and existing frame 15, and the exterior side portion 57 of the intermediate waterproof tape 2b is attached overlapping the exterior waterproof tape 2a, so even if rainwater seeps in between the existing frame 4 and the renovated frame 1, it can be prevented from seeping into the main body 7. Furthermore, a step 59 is formed by the exterior end of the intermediate waterproof tape 2b (see Figure 4), and this step 59 makes it difficult for rainwater that seeps in between the existing frame 4 and the renovated frame 1 to reach the interior side. If waterproof tape were to be applied from the indoor side of the existing frame 4 across the floorboards 17 and existing frame 15 to prevent rainwater from seeping into the main body 7, it would be necessary to use a wide waterproof tape that is 70 mm or wider, and it would be extremely difficult to apply such wide waterproof tape neatly and straight without creating wrinkles.However, by applying the waterproof tape separately to the outdoor waterproof tape 2a and the intermediate waterproof tape 2b, as in this renovated sash, it is possible to use relatively narrow widths (35 mm or 50 mm) for each waterproof tape 2a, 2b, making it easier to apply the waterproof tapes 2a, 2b. Furthermore, this renovated sash has an interior waterproofing tape 2c that runs from the interior side of the renovated frame 1 to the intermediate waterproofing tape 2b, so that even if rainwater seeps in between the existing frame 4 and the renovated frame 1, it can be prevented from seeping inside the room. The interior waterproofing tape 2c can be made relatively narrow, just like the exterior waterproofing tape 2a and intermediate waterproofing tape 2b, so it is easy to apply.

[0015] As shown in Figures 4 and 5, the bottom frame 40 of the renovation frame 1 is provided with a hanging stopper 41 to prevent the exterior side from sagging under the weight of the shoji screens 9 and 10, and a rotation-restricting element 42 to restrict the rotation of the hanging stopper 41. More specifically, the exterior end of the bottom frame 26 of the perimeter frame 19 has a groove 43 with a roughly U-shaped cross section that opens toward the exterior. The hanging stopper 41 and the rotation-restricting element 42 are fastened to the groove 43 by screws 44 and 45, respectively, from the exterior side. As shown in Figure 5, the lower wall of the groove 43 has a notch 46 that allows the hanging stopper 41 to protrude downward. Reference numeral 47 in the figure denotes a back plate with female-threaded holes that engage with the screws 44 and 45. The hanging stoppers 41 and the rotation-restricting element 42 are provided at intervals along the length of the bottom frame 40, for example, at three locations: on both the left and right sides and in the center.

[0016] The sagging stopper 41 is formed from a metal plate and, as shown in Figure 5, is rotatable around the axis of the screw 44 as a fulcrum.It can be rotated downward to protrude downward from the lower frame 40, and its lower end abuts against the upper surface 13a of the lower frame 13 of the existing frame 4, thereby using the lower end 41a as a support to prevent the lower frame 40 from sagging. The rotation restricting part 42 is formed from a metal plate, has a left-right elongated hole 48 through which a screw 45 is inserted, and is held within the groove 43 of the lower frame 40 so as to be slidable in the longitudinal direction of the lower frame 26 within the range of the elongated hole 48. As shown in FIG. 5, the rotation restricting part 42 has diagonally chamfered lower left and right corner portions 49, and by abutting the corner portions 49 against the hanging stopper 41 which has been rotated downward and tightening the screws 45 to fix the rotation restricting part 42, the hanging stopper 41 is restricted from rotating upward. As shown in Figure 4, the cover piece 32 of the lower frame 40 is attached detachably by engaging a pair of claw pieces 50, 50 with the groove 43 of the lower frame 40, and by attaching the cover piece 32, the hanging stopper 41 and the rotation restriction part 42 are hidden by the cover piece.

[0017] When fitting the reform frame 1 to the inner periphery of the existing frame 4, as shown in Figure 6(a), the rotation restriction part 42 is slid away from the hanging stopper 41, and the hanging stopper 41 is rotated upward so that it barely protrudes from the lower frame 40. Once the reform frame 1 is placed inside the existing frame 4, the rotation restriction component 42 is slid toward the sagging stop 41, as shown in FIG. 6(b). This sliding of the rotation restriction component 42 can be achieved by placing the tip of a tool such as a screwdriver against the recess 60 formed on the side edge of the rotation restriction component 42 and striking the handle of the tool with a hammer. The sagging stop 41 is pressed downward by the corner portion 49 of the rotation restriction component 42, and the lower end of the sagging stop 41 abuts against the upper surface 13a of the bottom frame 13 of the existing frame 4. Then, by tightening the screws 44 and 45 to fix the sagging stop 41 and the rotation restriction component 42, the bottom frame 40 is supported by the lower end 41a of the sagging stop 41, preventing the bottom frame 40 from sagging. Thereafter, when the cover piece 32 is attached by engaging it with the groove 43 of the lower frame 40, the hanging stopper 41 and the rotation restricting part 42 are hidden by the cover piece 32.

[0018] The resin frame 8 is made of extruded resin material. As shown in Figures 1 and 2, it has a front surface 51 that extends indoors, continuing from the resin angle 24 of the new frame 18, and a facing surface 52 that extends from the interior end of the facing surface 51 toward the periphery. The resin angle 24 of the new frame 18 is screwed to the facing surface 51 from the inside with screws 53. The facing surface 52 has multiple breakable sections 54 spaced apart on the exterior side, allowing the facing surface 52 to be broken off appropriately using the breakable sections 54 depending on the distance from the existing frame 15 to the resin angle 24 of the new frame 18, thereby adjusting the facing dimension. An angle-shaped decorative material 55 is attached to the existing frame 15, and the decorative material 55 hides the gap between the tip of the facing surface 52 and the existing frame 15. By attaching the resin frame 8 in this way, the existing frame 4, resin board 5, and reform frame 1 are hidden by the resin frame 8, resulting in a good design. Moreover, the resin frame 8 is formed with an L-shaped cross section, with a visible surface 51 that continues with the resin angle 24 of the new frame 18, and a visible surface 52 that extends from the interior end of the visible surface 51 toward the outer periphery, further improving the interior design.

[0019] Next, we will explain the construction procedure for this remodeled sash. First, as shown in Figures 8 and 9, the mounting support material 5 is placed on the indoor side of the existing frame 4, and the outdoor waterproof tape 2a is applied continuously around four sides, straddling the indoor side of the existing frame 4 and the mounting support material 5. Next, the outdoor side portion 57 is overlapped on the outdoor waterproof tape 2a, and the intermediate waterproof tape 2b is applied continuously around four sides, straddling the mounting support material 5, the existing frame 15, and the floorboard 17. Next, the reform frame 1 is assembled. The reform frame 1 is assembled by positioning the upper and lower frames 25 and 26 of the outer frame 19 and the left and right vertical frames 27, 27 around the pre-framed new frame 18 using the positioning parts 35, and then fitting them from the outer periphery. As shown in Figure 7, the end faces of the upper and lower frames 25, 26 are butted against the inner periphery of the vertical frames 27, 27 via the sealing material 28, and screws inserted through the vertical frames 27, 27 from the side are screwed into the tapping holes 30 of the upper and lower frames 25, 26 to complete the framing. The water-stopping material 3 is then attached by gluing it to a predetermined position in the projection direction on the outer periphery of the reform frame 1. The reform frame 1 can be assembled at the sash construction site, or it can be assembled in a factory and transported to the construction site. Next, the renovation frame 1, which is made by integrating the new frame 18 and the outer peripheral frame 19 as described above, is fitted from the outside of the room into the opening 6 to which the existing frame 4 is attached, as shown in Figures 8 and 9, and the renovation frame 1 is positioned in the forward direction so that the indoor end of the renovation frame 1 (the indoor end of the outer peripheral frame 19) coincides with the indoor end of the mounting support material 5. In addition, the cover piece 32 of the lower frame 40 of the reform frame 1 is first removed, and as described above, the hanging stopper 41 is rotated downward so that the lower end of the hanging stopper 41 abuts against the upper surface 13a of the lower frame 13 of the existing frame 4, and the rotation control part 42 is fixed in a position where it abuts against the hanging stopper 41, and then the cover piece 32 is attached. Thereafter, the reform frame 1 is fixed to the main body 7 from the inner periphery on the inside of the room with screws 34. Then, the indoor waterproof tape 2c is applied continuously around four circumferences so as to straddle the indoor part of the reform frame 1 and the intermediate waterproof tape 2b. Thereafter, a resin frame 8 is attached from the inside of the room. In addition, the reform frame 1 may be placed in the opening 26 without attaching the cover piece 32 to the lower frame 40 of the reform frame 1, and the cover piece 32 may be attached after adjusting the sagging stopper 41 and the rotation restriction part 42.

[0020] In this way, this remodeled sash is easy to install because the new frame 18, which is framed all around, is surrounded by the outer frame 19, and the new frame 18 and outer frame 19, when integrated, are fitted into the opening 6 to which the existing frame 4 is attached from the outside of the room, and the outer frame 19 is fixed to the frame 7, eliminating the need to process the existing frame 4 or attach components to the inner periphery of the existing frame 4. Fixing the outer frame 19 to the frame 7 from the inside of the room further improves installability. Furthermore, this renovated sash has an exterior waterproof tape 2a extending from the interior side of the existing frame 4 to the mounting support material 5, an intermediate waterproof tape 2b extending from the mounting support material 5 to the existing frame 15 and floorboard 17 while overlapping the exterior side 57 onto the exterior waterproof tape 2a, and an interior waterproof tape 2c extending from the interior side of the reformed frame 1 to the intermediate waterproof tape 2b, so that even if rainwater seeps in between the existing frame 4 and the reformed frame 1, it can be prevented from seeping into the frame 7 or the interior of the room. Each waterproof tape 2a, 2b, 2c can be relatively narrow, making it easy to apply the waterproof tapes 2a, 2b, 2c.

[0021] Figure 10 shows a second embodiment of the remodeled sash of the present invention. Like the first embodiment, this remodeled sash is applied to a double-sliding French door window. It includes an outer-periphery mounting support 5a on the interior side of the angle 16 of the bottom frame 13 of the existing frame 4, and an inner-periphery mounting support (indoor component) 5b extending from the angle 16 to the inner periphery of the outer-periphery mounting support 5a. Furthermore, like the first embodiment, an exterior waterproofing tape 2a extends from the exterior side of the interior wall 39 of the bottom frame 13 of the existing frame 4 to the inner periphery of the inner-periphery mounting support 5b, an intermediate waterproofing tape 2b extends from the exterior waterproofing tape 2a to the floorboard 17, and an interior waterproofing tape 2c extends from the interior side of the bottom frame 26 of the remodeled frame 1 (periphery frame 19) to the intermediate waterproofing tape 2b.

[0022] In the renovated sash of the second embodiment, as in the first embodiment, even if rainwater seeps in through the gap between the existing frame 4 and the renovated frame 1, the exterior waterproofing tape 2a and the intermediate waterproofing tape 2b can prevent the rainwater from seeping into the frame 7, and the interior waterproofing tape 2c can further prevent the rainwater from seeping inside the room. By overlapping the inner peripheral side mounting auxiliary member 5b on the inner peripheral side of the outer peripheral side mounting auxiliary member 5a, it becomes even easier to adjust the mounting position of the renovated frame 1.

[0023] Figure 11 shows a third embodiment of the remodeled sash of the present invention. This remodeled sash is applied to a waist-high sliding window. The bottom frame 13 of the existing frame 4 does not have an angle 16. An existing frame 15 is attached to the interior side of the bottom frame 13, and a mounting support member (indoor component) 5 is attached to the interior periphery of the existing frame 15. An exterior waterproof tape 2a is attached from the exterior side of the interior wall 39 of the bottom frame 13 of the existing frame 4 to the interior side of the mounting support member 5. An intermediate waterproof tape 2b is attached from the exterior waterproof tape 2a to the interior side of the mounting support member 5. An interior waterproof tape 2c is attached from the interior side of the bottom frame 26 of the remodeled frame 1 (periphery frame 19) to the intermediate waterproof tape 2b.

[0024] As with the first embodiment, even if rainwater seeps in through the gap between the existing frame 4 and the renovated frame 1, the renovated sash of the third embodiment can prevent the rainwater from seeping into the main body 7 by the outdoor waterproof tape 2a and the intermediate waterproof tape 2b, and can further prevent the rainwater from seeping inside the room by the indoor waterproof tape 2c.

[0025] Figure 12 shows a fourth embodiment of the remodeled sash of the present invention. Like the third embodiment, this remodeled sash is applied to a waist-high sliding window. The bottom frame 13 of the existing frame 4 does not have an angle 16. An existing frame (interior component) 15 is attached to the interior side of the bottom frame 13. An exterior waterproof tape 2a is attached from the exterior side of the interior wall 39 of the bottom frame 13 of the existing frame 4 to the interior side of the existing frame 15. An intermediate waterproof tape 2b is attached to the interior side of the existing frame 15, overlapping the exterior portion 57 of the bottom frame 13 with the exterior waterproof tape 2a. An interior waterproof tape 2c is attached from the interior side of the bottom frame 26 of the remodeled frame 1 (periphery frame 19) to the intermediate waterproof tape 2b. The bottom frame 40 of the reform frame 1 is placed directly on the existing frame 15 without using the mounting support material 5 (waterproof tapes 2a, 2b are placed between the bottom frame 40 of the reform frame 1 and the existing frame 15), and is fixed to the main body 7 with screws 34 from the inner side.

[0026] As with the first embodiment, even if rainwater seeps in through the gap between the existing frame 4 and the reformed frame 1, the exterior waterproofing tape 2a and the intermediate waterproofing tape 2b can prevent the rainwater from seeping into the frame 7, and the interior waterproofing tape 2c can further prevent the rainwater from seeping inside the room. By placing the bottom frame 40 of the reformed frame 1 directly on the existing frame 15, construction can be simplified.

[0027] As described above, this renovated sash (first, second, third and fourth embodiments) comprises a reform frame 1 provided on the inner periphery of the existing frame 4, an outdoor waterproof tape 2a, an intermediate waterproof tape 2b and an indoor waterproof tape 2c, the outdoor waterproof tape 2a being provided across from the indoor side of the existing frame 4 to the indoor side components (mounting auxiliary material 5, inner periphery mounting auxiliary material 5b, existing frame 15) located on the indoor side of the existing frame 4, the outdoor side portion 57 of the intermediate waterproof tape 2b being overlapped on the outdoor waterproof tape 2a and attached to the indoor side components 5, 5b and 15, and the indoor side waterproof tape 2c being provided across the reform frame 1 and the intermediate waterproof tape 2b, which makes it easy to apply the waterproof tapes 2a, 2b and 2c, resulting in good workability. Furthermore, the outdoor side portion 57 of the intermediate waterproof tape 2b is overlapped on the outdoor side waterproof tape 2a, and the indoor side waterproof tape 2c is provided across the renovation frame 1 and the intermediate waterproof tape 2b, thereby preventing rainwater from seeping into the main body 7 or the inside of the room. By using the exterior waterproof tape 2a, the intermediate waterproof tape 2b, and the interior waterproof tape 2c with a specified width of 50 mm or less, the work of applying the waterproof tapes 2a, 2b, and 2c can be standardized regardless of the construction site, making the work of applying the waterproof tapes 2a, 2b, and 2c even easier. This remodeled sash (first, second and third embodiments) has mounting auxiliary materials 5, 5a and 5b for adjusting the mounting position of the reform frame 1, so that the mounting position of the reform frame 1 can be easily adjusted, improving workability.

[0028] The manufacturing method for this remodeled sash (first, second, third, and fourth embodiments) involves applying an exterior waterproofing tape 2a from the interior side of the existing frame 4 to the interior components (mounting support 5, inner peripheral mounting support 5b, and existing frame 15) located on the interior side of the existing frame 4. Then, the intermediate waterproofing tape 2b is applied to the interior components 5, 5b, and 15, overlapping the exterior portion 57 of the exterior waterproofing tape 2a. Then, the remodeled frame 1 is placed inside the existing frame 4, and the interior waterproofing tape 2c is applied across the remodeled frame 1 and the intermediate waterproofing tape 2b. This simplifies the application of the waterproofing tapes 2a, 2b, and 2c, resulting in excellent workability. Furthermore, by overlapping the exterior portion 57 of the intermediate waterproofing tape 2b with the exterior waterproofing tape 2a, and applying the interior waterproofing tape 2c across the remodeled frame 1 and the intermediate waterproofing tape 2b, rainwater can be prevented from seeping into the main frame 7 or the interior of the room.

[0029] The present invention is not limited to the above-described embodiments. The specific structure of the remodeling frame can be modified as needed, and it is not limited to a double structure consisting of a new frame and an outer frame, but may also be a single frame. The exterior waterproofing tape need only be installed across the interior side of the existing frame to the interior side component located on the interior side of the existing frame, and the interior side component may be any component. The present invention is not limited to sliding windows, but can be applied to any sash, such as sliding windows, fixed windows, back doors, and sliding entrance doors. [Explanation of symbols]
