[0007] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 5 show a first embodiment of the remodeled sash of the present invention. This remodeled sash is applied to a bay-type sliding window, and as shown in Figures 1 and 2, includes a remodeled frame 1 that is fitted from the outside of the room into an opening 6 to which an existing frame 4 is attached and fixed to a framework 7, a resin frame 8 that is attached to the inside of the remodeled frame 1, and an outer screen 9, an inner screen 10, and a screen door 11 that are slidably fitted 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 shaped material, and is attached to the main body 7 in a so-called semi-external state. An existing wooden frame (indoor member) 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 attached, and a floorboard (indoor member) 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 peripheral 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 material. The upper frame 20 and the lower frame 21 are insulated by providing 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 structure of a semi-external sash frame of a regular sash or ordinary sash that 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 made of aluminum extrusions. More specifically, the longitudinal end faces of the upper frame 25 and the lower frame 26 are butted against the inner peripheral side faces of the vertical frames 27, 27 via a sealing material 28 (see FIG. 7), and the framework is formed by screwing screws 29 (see FIG. 7) inserted through the vertical frames 27, 27 from the side into tapping holes 30 (see FIG. 1) of the upper and lower frames 25, 26. 1 and 2, the upper frame 25, the lower frame 26, and the 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 exterior end of the main member 31 and extends toward the outer periphery. Each cover piece 32 overlaps with the exterior side of the exterior 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 33 that extends further inside the room than the indoor side walls of the new frame 18 and the existing frame 4, and the extension 33 is fixed to the main body 7 with screws 34 from the inner periphery side. 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 side, 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 depending on the shape of the existing frame 4, etc.

[0011] 1 and 2, an airtight material 37 is provided continuously around the 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 fin for fixing the new frame 18 to the body was broken off. By providing the airtight material 37 continuously around the 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 side 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 side walls 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 material (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 material 5 is formed, for example, from a wooden board, and the upper surface of the auxiliary mounting material 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 side 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 material 5. Further, an intermediate waterproof tape 2b is provided across the upper surface of the mounting auxiliary material 5 and the upper surface of the floor board 17. The intermediate waterproof tape 2b has an outdoor side portion 57 overlapping and affixed to the inner periphery side of the outdoor side waterproof tape 2a. Furthermore, an indoor waterproof tape 2c is provided spanning from the indoor side part 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 a commercially available waterproof tape of an appropriate width, and is attached along the longitudinal direction 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 10 mm or more), 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, which will be described later). If the waterproof tapes 2b and 2c are wide and extend beyond the resin frame 8, the excess portion is cut off. However, without being limited to the above, it is also possible to use a 35 mm or 50 mm wide tape for the exterior waterproof tape 2a, and a 35 mm wide tape for the intermediate waterproof tape 2b and the interior waterproof tape 2c.

[0013] As shown in FIG. 1, the mounting auxiliary material 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, and the outdoor waterproof tape 2a is provided across the outdoor side of the indoor wall 39 of the upper frame 12 of the existing frame 4 and the indoor side of the mounting auxiliary material 5. In addition, the intermediate waterproof tape 2b is provided across the indoor side of the mounting auxiliary material 5 and the indoor side of the existing frame 15. The outdoor side portion 57 of the intermediate waterproof tape 2b is attached overlapping the outdoor waterproof tape 2a. Furthermore, the indoor waterproof tape 2c is provided from the indoor side of the upper frame 25 of the reform frame 1 (peripheral frame 19) to the intermediate waterproof tape 2b. Each waterproof tape 2a, 2b, 2c is attached along the longitudinal direction of the upper frame 12 of the existing frame 4. As shown in FIG. 2, the mounting auxiliary material 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, and the outdoor waterproof tape 2a is provided across the outdoor side of the indoor wall 39 of the vertical frame 14 of the existing frame 4 and the indoor side of the mounting auxiliary material 5. In addition, the intermediate waterproof tape 2b is provided across the indoor side of the mounting auxiliary material 5 and the indoor side of the existing frame 15. The outdoor side portion 57 of the intermediate waterproof tape 2b is attached overlapping the outdoor waterproof tape 2a. Furthermore, the indoor waterproof tape 2c is provided from the indoor side of the vertical frame 27 of the reform frame 1 (peripheral frame 19) to the intermediate waterproof tape 2b. Each waterproof tape 2a, 2b, 2c is attached along the longitudinal direction of the vertical frame 14 of the existing frame 4. The four outer waterproof tapes 2a, the intermediate waterproof tapes 2b and the inner waterproof tapes 2c mentioned above are each provided at the same position in the prospective direction and are provided contiguous to each other so that there are no gaps between the ends.

[0014] In this remodeled sash, the exterior waterproof tape 2a is provided from the interior side of the existing frame 4 to the auxiliary mounting material 5, the intermediate waterproof tape 2b is provided from the auxiliary mounting material 5 to the floor board 17 and existing frame 15, and the exterior side part 57 of the intermediate waterproof tape 2b is overlapped and attached onto the exterior waterproof tape 2a, so that even if rainwater seeps in between the existing frame 4 and the remodeled frame 1, it can be prevented from seeping into the framework 7. Moreover, a step 59 is formed by the exterior side end of the intermediate waterproof tape 2b (see Figure 4), and the presence of this step 59 makes it difficult for rainwater that seeps in between the existing frame 4 and the remodeled frame 1 to flow to the interior side. If one were to apply waterproof tape from the indoor side of the existing frame 4 across the floorboards 17 and existing frame 15 to prevent rainwater from entering the main structure 7, it would be necessary to use a wide waterproof tape that is 70 mm or more wide, and it would be extremely difficult to apply such a wide waterproof tape neatly and straight without creating wrinkles. However, by applying the tape separately to the outdoor side 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 remodeled sash has an interior waterproof tape 2c that is provided from the interior side of the remodeled frame 1 across the intermediate waterproof tape 2b, so that even if rainwater seeps in between the existing frame 4 and the remodeled frame 1, it can prevent the rainwater from seeping in to the interior side. The interior waterproof tape 2c can be made relatively narrow, just like the exterior waterproof tape 2a and intermediate waterproof tape 2b, so it is easy to apply.

[0015] As shown in Figs. 4 and 5, the bottom frame 40 of the reform frame 1 is provided with a hanging stopper 41 to prevent the outside from sagging due to the weight of the shoji screens 9 and 10, and a rotation restriction part 42 to restrict the rotation of the hanging stopper 41. More specifically, the outside end of the bottom frame 26 of the outer periphery frame 19 is provided with a groove 43 with a roughly U-shaped cross section that opens toward the outside of the room, and the hanging stopper 41 and the rotation restriction part 42 are screwed into the groove 43 with screws 44 and 45 from the outside of the room. As shown in Fig. 5, the lower wall of the groove 43 is provided with a notch 46 so that the hanging stopper 41 can be protruded downward. The reference number 47 in the figure is a back plate formed with female screw holes into which the screws 44 and 45 are screwed. The hanging stopper 41 and the rotation restriction part 42 are provided at intervals in the longitudinal direction 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 of a metal plate and, as shown in Figure 5, is rotatably mounted on the axis of the screw 44 as a fulcrum. It is rotated downward to protrude downward from the lower frame 40, and its lower end is abutted against the upper surface 13a of the lower frame 13 of the existing frame 4, thereby preventing the lower frame 40 from sagging by using the lower end portion 41a as a support. The rotation restricting part 42 is formed from a metal plate, has a left-right long hole 48 through which a screw 45 is inserted, and is held in a groove 43 of the lower frame 40 within the range of the long hole 48 so as to be slidable in the longitudinal direction of the lower frame 26. As shown in Fig. 5, the rotation restricting part 42 has left and right lower corner portions 49 that are beveled at an angle, and by bringing the corner portions 49 into contact with the hanging stopper 41 that has been rotated downward and tightening the screw 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 removably attached by engaging a pair of claw pieces 50, 50 with a groove 43 of the lower frame 40, and by attaching the cover piece 32, the sagging stopper 41 and the rotation restriction part 42 are hidden by the cover piece.

[0017] When fitting the reform frame 1 into the inner circumference 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. After the reform frame 1 is placed on the inner periphery of the existing frame 4, the rotation restriction part 42 is slid in a direction approaching the sagging stopper 41 as shown in FIG. 6(b). The rotation restriction part 42 can be slid by placing the tip of a tool such as a screwdriver against the recess 60 formed on the side edge of the rotation restriction part 42 and hitting the handle of the tool with a hammer. The sagging stopper 41 is pushed by the corner part 49 of the rotation restriction part 42 and rotates downward, and the lower end of the sagging stopper 41 abuts against the upper surface 13a of the lower frame 13 of the existing frame 4. After that, if the screws 44 and 45 are tightened to fix the sagging stopper 41 and the rotation restriction part 42, the lower frame 40 is supported by the lower end part 41a of the sagging stopper 41 as a support part, and the sagging of the lower frame 40 can be prevented. 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 a resin extruded material, and as shown in Figs. 1 and 2, has a projection surface 51 that extends from the interior side of the room to the resin angle 24 of the new frame 18, and a facing surface 52 that extends from the interior end of the projection surface 51 toward the outer periphery. The resin angle 24 of the new frame 18 is screwed to the projection surface 51 with a screw 53 from the inner periphery side. The facing surface 52 has a plurality of breakable parts 54 at intervals in the inner and outer periphery directions on the exterior side of the room, and the facing surface 52 can be appropriately broken off with the breakable parts 54 according to the distance from the existing frame 15 to the resin angle 24 of the new frame 18, so that the facing dimension can be adjusted. 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 to the outer periphery, thereby further improving the interior design.

[0019] Next, the construction procedure for this remodeled sash will be explained. 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 all four sides so as to straddle the indoor part of the existing frame 4 and the mounting support material 5. Next, the intermediate waterproof tape 2b is applied continuously around all four sides so as to straddle the mounting support material 5, the existing frame 15, and the floorboard 17, with the outdoor part 57 overlapping the outdoor waterproof tape 2a. Next, the reform frame 1 is assembled. The reform frame 1 is assembled by positioning the upper frame 25 and lower frame 26 of the outer peripheral frame 19 and the left and right vertical frames 27, 27 around the previously framed new frame 18 with the positioning parts 35, and then, as shown in FIG. 7, the end faces of the upper and lower frames 25, 26 are butted against the inner peripheral side surfaces of the vertical frames 27, 27 via the sealing material 28, and the screws inserted into the vertical frames 27, 27 from the side are screwed into the tapping holes 30 of the upper and lower frames 25, 26 to frame the frame. After that, the water-stopping material 3 is attached by bonding to a predetermined position in the prospective direction of the outer peripheral side surface of the reform frame 1. The reform frame 1 may be assembled at the sash construction site, but it can also 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 prospective direction so that the indoor side end of the renovation frame 1 (the indoor side end of the outer peripheral frame 19) coincides with the indoor side end of the mounting support material 5. In addition, the cover piece 32 of the bottom frame 40 of the reform frame 1 is temporarily 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 bottom 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 renovation frame 1 is fixed to the main body 7 from the inner circumference side on the inside of the room with screws 34. Then, the indoor waterproof tape 2c is applied continuously around four sides 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 into the opening 26 without attaching the cover piece 32 to the bottom 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 has a framework on all four sides, is surrounded by the outer frame 19, and the new frame 18 and the outer frame 19, as one unit, 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 main body 7, eliminating the need to process the existing frame 4 or attach components to the inner side of the existing frame 4. Fixing the outer frame 19 to the main body 7 from the inside of the room further improves ease of installation. In addition, this remodeled sash has an exterior waterproof tape 2a extending from the interior side of the existing frame 4 to the auxiliary mounting material 5, an intermediate waterproof tape 2b extending from the auxiliary mounting 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 framework 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] 10 shows a second embodiment of the remodeled sash of the present invention. This remodeled sash is applied to a sliding window of a bay window type, as in the first embodiment, and an outer peripheral side mounting auxiliary material 5a is provided on the indoor side of the angle 16 of the bottom frame 13 of the existing frame 4, and an inner peripheral side mounting auxiliary material (indoor member) 5b is provided across the angle 16 and the inner peripheral side of the outer peripheral side mounting auxiliary material 5a. In addition, as in the first embodiment, an outdoor waterproof tape 2a is provided across the indoor side of the indoor side wall 39 of the bottom frame 13 of the existing frame 4 to the inner peripheral side of the inner peripheral side mounting auxiliary material 5b, an intermediate waterproof tape 2b is provided across the outdoor waterproof tape 2a to the floor board 17, and an indoor waterproof tape 2c is provided across the indoor side of the bottom frame 26 of the reformed frame 1 (outer peripheral frame 19) to the intermediate waterproof tape 2b.

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

[0023] Fig. 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, and an existing frame 15 is provided on the indoor side of the bottom frame 13, and an attachment auxiliary material (indoor member) 5 is provided on the inner periphery of the existing frame 15. In addition, an outdoor waterproof tape 2a is provided from the outdoor side of the indoor wall 39 of the bottom frame 13 of the existing frame 4 to the inner periphery side of the attachment auxiliary material 5, an intermediate waterproof tape 2b is provided from the outdoor waterproof tape 2a to the indoor side of the attachment auxiliary material 5, and an indoor waterproof tape 2c is provided from the indoor side of the bottom frame 26 of the reformed frame 1 (periphery frame 19) to the intermediate waterproof tape 2b.

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

[0025] Fig. 12 shows a fourth embodiment of the remodeled sash of the present invention. This remodeled sash is applied to a waist-high sliding window, as in the third embodiment. The bottom frame 13 of the existing frame 4 does not have an angle 16, and an existing frame (indoor member) 15 is provided on the indoor side of the bottom frame 13. An outdoor waterproof tape 2a is provided from the outdoor side of the indoor wall 39 of the bottom frame 13 of the existing frame 4 to the inner peripheral side of the existing frame 15, an intermediate waterproof tape 2b is provided on the inner peripheral side of the existing frame 15 with the outdoor part 57 overlapping the outdoor waterproof tape 2a, and an indoor waterproof tape 2c is provided from the indoor side of the bottom frame 26 of the reformed frame 1 (peripheral 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 the aid of an installation support material 5 (waterproof tapes 2a, 2b are interposed 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] In the remodeled sash of the fourth embodiment, as in the first embodiment, even if rainwater seeps in through the gap between the existing frame 4 and the remodeled frame 1, the exterior waterproof tape 2a and the intermediate waterproof tape 2b can prevent the rainwater from seeping into the frame 7, and the interior waterproof tape 2c can further prevent the rainwater from seeping into the room. By directly placing the bottom frame 40 of the remodeled frame 1 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 exterior waterproof tape 2a, an intermediate waterproof tape 2b and an interior waterproof tape 2c, the exterior waterproof tape 2a being provided across from the interior side of the existing frame 4 to the interior members (mounting auxiliary material 5, inner periphery mounting auxiliary material 5b, existing frame 15) located on the interior side of the existing frame 4, the exterior side portion 57 of the intermediate waterproof tape 2b being overlapped on the exterior waterproof tape 2a and affixed to the interior members 5, 5b and 15, and the interior 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 penetrating 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. Since the present 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, the mounting position of the reform frame 1 can be easily adjusted, improving workability.

[0028] The manufacturing method of this remodeled sash (first, second, third, and fourth embodiments) is to apply the outdoor waterproof tape 2a from the indoor side of the existing frame 4 to the indoor side members (attachment auxiliary material 5, inner periphery side attachment auxiliary material 5b, existing frame 15) located on the indoor side of the existing frame 4, and apply the intermediate waterproof tape 2b to the indoor side members 5, 5b, and 15 by overlapping the outdoor side portion 57 on the outdoor waterproof tape 2a, and then to place the remodeled frame 1 on the inner periphery of the existing frame 4, and apply the indoor side waterproof tape 2c across the remodeled frame 1 and the intermediate waterproof tape 2b, which makes it easy to apply the waterproof tapes 2a, 2b, and 2c, and therefore makes the work of construction easy. Moreover, the outdoor side portion 57 of the intermediate waterproof tape 2b is overlapped on the outdoor waterproof tape 2a, and the indoor side waterproof tape 2c is applied across the remodeled frame 1 and the intermediate waterproof tape 2b, which makes it possible to prevent rainwater from infiltrating into the frame 7 or the room side.

[0029] The present invention is not limited to the above-described embodiment. The specific structure of the reform frame can be changed as appropriate, and it is not limited to a double structure of a new frame and an outer frame, but may be a single frame. The exterior waterproof tape only needs to be provided across the interior part of the existing frame from the interior part to the interior part of the existing frame, and the interior part may be any material. The present invention is not limited to sliding windows, but can be applied to any sash, such as sliding windows, fixed windows, back door doors, and entrance sliding doors. [Explanation of symbols]
