BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. Figures 1 and 2 show a first embodiment of the retrofit sash of the invention. This refurbished sash is applied to a double sliding window, and is attached to the remodeling frame 3 which 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 the remodeling frame 3 on the indoor side. It has a resin frame 27, an outer shoji 28, an inner shoji 29 and a screen door 30 which are slidably housed along the upper and lower lateral frames of the reform frame 3. - 特許庁

The existing frame 4 is a sash frame without angles for double sliding windows, and as shown in FIGS. , and attached to the frame 5 in a so-called semi-external state. An existing wooden frame 34 is provided on the indoor side of the existing frame 4 .

The renovation frame 3 is composed of a new frame 1 and an outer frame 2 surrounding the new frame 1, as shown in FIGS.
The newly installed frame 1 is constructed by forming an upper frame 35, a lower frame 36, and left and right vertical frames 37, 37 made of an aluminum shape member. The upper frame 35 and the lower frame 36 are insulated by providing a heat insulating bridge 38 at an intermediate portion in the viewing direction. Also, the new frame 1 is provided with a resin angle 39 on the indoor side to prevent dew condensation on the indoor side.
The new frame 1, as shown in FIG. 7, is obtained by breaking off a fin 40 for fixing the skeleton of a general semi-external sash frame.

As shown in FIG. 8, the new frame 1 is provided with metal reinforcing plates 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 positions on the upper and lower sides of the outer peripheral side of the vertical frame 37 at positions on the sides of the upper frame 35 and the lower frame 36. Screws 41 pass through the reinforcing plate 25 and the vertical frame 37 from the outer peripheral side. are screwed into the tapping holes 42 of the upper frame 35 and the lower frame 36 to fasten the reinforcing plate 25 and the vertical frame 37 to the upper frame 35 and the lower frame 36 together. 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 abuts a piece 44 protruding toward the outer peripheral side of the vertical frame 37 at its outdoor-side end.

In this way, the reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 37, and the reinforcing plate 25 and the vertical frame 37 are fastened together to the horizontal frames (upper frame, lower frame) 35, 36 with the screws 41. It is possible to prevent the vertical frame 37 from being deformed so as to expand to the outer peripheral side when the door is closed forcefully, and watertightness can be maintained. The effect of preventing deformation of the vertical frame 37 is enhanced by abutting the end portion of the reinforcement plate 25 on the outdoor side against the piece 44 projecting toward the outer peripheral side of the vertical frame 37 . It should be noted that the fact that the reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 37 of the new frame 1 is the same for the second, fourth and fifth embodiments, which will be described later.

As shown in FIGS. 1 to 4, the outer peripheral frame 2 is composed of an upper frame 45, a lower frame 46, and left and right vertical frames 47, 47 made of an aluminum profile. More specifically, the longitudinal end surfaces of the upper frame 45 and the lower frame 46 are abutted against the inner peripheral side surfaces of the vertical frames 47, 47 via the sealing material 56 (see FIGS. 2 and 3), and the vertical frames are pushed from the sides. The framework 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 detachably attached to a main member 49 extending in the direction of projection and to the outdoor end of the main member 49. 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 portion 51 that extends toward the interior of the room from the indoor side wall of the new frame 1 and the existing frame 4. The extension portion 51 is provided with screws for fixing the remodeling frame 3 to the frame 5. A hole 53 through which 52 is inserted is provided. The main member 49 is provided with positioning portions 54 at two locations, one on the outdoor side and the other on the indoor side. Thus, the upper frame 45, the lower frame 46 and the vertical frame 47 of the outer peripheral frame 2 can be positioned in the viewing direction, and the new frame 1 and the outer peripheral frame 2 can be integrated. The cover piece 50 has a plurality of breakable portions 55 provided at intervals in the inner and outer peripheral directions on the inner side surface of the room. You can change the dimensions.

As shown in FIGS. 1 and 2, airtight members 57a, 57b, 57c, and 57d are continuously provided in the gap between the outer peripheral side surface of the new frame 1 and the inner peripheral side surface of the outer peripheral frame 2. As shown in FIGS. The airtight members 57a, 57b, 57c, and 57d are provided at positions where the fins 40 of the new frame 1 are broken off.
The vertical frame 47 of the outer peripheral frame 2 is provided with a sealing material 56 at the joint portion with the end faces of the horizontal frames (upper frame, lower frame) 45, 46, and extends along the horizontal frames 45, 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 member 56. 57a, 57b and vertical airtight members 57c, 57d are continuous. This prevents rainwater from entering the room through the gap between the new frame 1 and the outer frame 2. - 特許庁
Also, the gap between the cover piece 50 of the upper frame 45 of the outer peripheral frame 2 and the outdoor side wall of the upper frame 31 of the existing frame 4, the cover pieces 50 of the vertical frames 47 of the outer peripheral frame 2 and the vertical frame of the existing frame 4 Airtight members 58a and 58b are also continuously provided in the gaps between the 33 and the outdoor side wall. This prevents rainwater from entering the gap between the reforming frame 3 and the existing frame 4. - 特許庁

As shown in FIGS. 1 and 2, on the inner peripheral side of the existing frame 34 on the indoor side of the existing frame 4, mounting aids 6 serving as a base for fixing the reforming frame 3 to the frame 5 are provided around the four sides. . The mounting support member 6 is made of an aluminum profile, and is formed into a U-shaped cross section by the projection walls 59a and 59b on the outside and inside of the room and the projection wall 60. As shown in FIG. A plurality of breakable portions 61 are provided at intervals in the inner and outer peripheral directions on the outdoor and indoor side walls 59a and 59b. The auxiliary mounting material 6 adjusts the width by appropriately breaking off the mounting walls 59a and 59b with the breakable portion 61 so that the position of the inner peripheral side surface of the mounting wall 60 protrudes most to the inner peripheral side of the existing frame 4. It is arranged to be positioned substantially at the same position in the inner and outer peripheral directions as the portion 62 which has been cut. 1 and 2, it appears that the attachment walls 59a and 59b are interfering with the existing frame 34, but in reality there is no portion that interferes with the existing frame 34 by being broken off by the breakable portion 61. FIG.
Each of the auxiliary mounting members 6 is arranged with the outdoor side wall 59a in contact with the indoor side wall of the existing frame 4, so that the position of the indoor side end of the mounting auxiliary member 6 is positioned from the outdoor side end of the existing frame 4 to a predetermined position. The mounting support member 6 is positioned in the viewing direction so that the dimension A (specifically, 110 mm) is obtained. The mounting support member 6 is fixed to the frame 5 with a screw 63 inserted through the projection wall 60 from the inner peripheral side.

As shown in FIGS. 1 and 2, the reforming frame 3 is positioned in the prospective direction so that the indoor-side end 64 of the outer peripheral frame 2 coincides with the indoor-side end of the mounting support member 6, and extends at the position of the mounting support member 6. It is fixed to the frame 5 with a screw 52 inserted into the projecting portion 51 from the inner peripheral side. Between the outer peripheral frame 2 and the mounting support member 6, a pet tree 65 is interposed as required.
In this refurbished sash, after attaching the auxiliary mounting material 6 in contact with the indoor side wall of the existing frame 4, the indoor side end 64 of (the outer peripheral frame 2 of) the reformed frame 3 is attached to the auxiliary mounting material 6. By positioning the remodeling frame 3 in the prospective direction so as to coincide with the indoor side end, the remodeling frame 3 is naturally arranged at an appropriate position in the prospective direction, and the cover piece 50 of the reforming frame 3 and the existing frame 4 are arranged in advance. The airtight members 58a and 58b provided on one of the side walls are in close contact with the other, and the space between the reforming frame 3 and the existing frame 4 is stopped on the outdoor side.

1 and 2, the existing frame side waterproof tape 7 is attached across the existing frame 4 and the mounting auxiliary material 6, and the projection wall 60 of the mounting auxiliary material 6 and the room inside are visible. A waterproof tape 66 for hiding screws is attached across the attached wall 59b, and a waterproof tape 8 on the side of the remodeling frame is provided across the remodeling frame 3 and the mounting auxiliary member 6. - 特許庁The screw hiding waterproof tape 66 hides the screws 63 that attach the auxiliary mounting material 6 to the frame 5, and the remodeling frame side waterproof tape 8 hides the screws 52 that attach the remodeling frame 3 to the frame 5. . The waterproof tapes 7, 8 and 66 are commercially available waterproof tapes having appropriate widths, and are attached continuously along the circumferential direction of the existing frame 4 and the reformed frame 3. As shown in FIG.

Thus, the refurbished sash has the existing frame side waterproof tape 7 attached across the existing frame 4 and the mounting auxiliary material 6, and the reformed frame side waterproof tape 8 attached across the mounting auxiliary material 6 and the reformed frame 3. Thus, even if rainwater enters between the reforming frame 3 and the existing frame 4 from the outdoor side, it is possible to prevent rainwater from entering the room. By providing an auxiliary mounting material 6 on the peripheral edge of the opening 26 and adhering the waterproof tapes 7 and 8 to the auxiliary mounting material 6, a smooth adhered surface for the waterproof tapes 7 and 8 can be ensured. Since 8 can be pasted cleanly, water stoppage is high. Further, rather than sticking a single waterproof tape over the existing frame 4 and the reformed frame 3, it is better to separate the waterproof tape 7 on the existing frame side and the waterproof tape 8 on the reformed frame side for better workability. Furthermore, since the screws 63 that attach the mounting aid 6 to the frame 5 are hidden by the waterproof tape 66 for screw hiding, rainwater can be prevented from entering the frame 5 through the holes of the screws 63 .

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

In this refurbished sash, the reinforcing member 24 is provided on the outer peripheral side of the remodeling frame 3, and the remodeling frame 3 and the reinforcing member 24 are fixed together to the frame 5 on the indoor side, so that the remodeling frame 3 is on the indoor side. Even if the remodeling frame 3 is fixed to the frame 5 in a cantilever manner at one end portion, it is possible to prevent the reform frame 3 from falling over to the inner peripheral side or the outer peripheral side with the fixing portion to the frame 5 as a fulcrum. Note that the points regarding the reinforcing member 24 are the same for the second to fifth embodiments described later.

Further, in this modified sash, as shown in FIG. 1, a gap adjustment part 72 is arranged at the outdoor end position 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 reformed frame 3. be. The gap adjusting component 72 is adjustable in height 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 detached from the outdoor side, and the gap adjusting part 72 is hidden by the cover piece 50.例文帳に追加
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 outdoor side of the lower frame 71 of the remodeling frame 3 hangs down. You can prevent it from deforming like this.

The resin picture frame 27 is made of an extruded shape made of resin, and as shown in FIGS. It has a viewing surface portion 74 extending toward the outer peripheral side from the portion. The resin angle 39 of the newly installed frame 1 is screwed to the projection surface portion 73 with a screw 75 from the inner peripheral side. The viewing surface portion 74 is provided with a plurality of breakable portions 76 spaced apart in the inner and outer peripheral directions on the outdoor side surface. is appropriately broken off by the snap-off portion 76 so that the width can be adjusted. An angle-shaped decorative material 77 is attached to the existing frame 34, and the gap between the tip of the viewing surface portion 74 and the existing frame 34 is hidden by the decorative material 77. - 特許庁
By attaching the resin frame 27 in this manner, the refurbished sash hides the existing frame 4, the mounting auxiliary member 6, and the reformed frame 3 with the resin frame 27, so that the design is excellent. Moreover, the resin picture frame 27 is formed to have an L-shaped cross section by the projection surface portion 73 which is continuous with the resin angle 39 of the new frame 1 and the projection surface portion 74 which extends from the indoor-side end of the projection surface portion 73 to the outer peripheral side. , the interior design can be further improved.

Next, the construction procedure of this refurbished sash will be explained. First, as shown in Figs. At that time, the auxiliary mounting member 6 is formed by appropriately breaking off the attachment walls 59a and 59b with the snap-off portion 61 so that the portion 62 protruding most to the inner peripheral side of the existing frame 4 and the allowance wall 60 of the attachment auxiliary member 6 are separated. After adjusting the width dimension so that they are substantially on the same plane in the projection direction, the projection wall 59a on the outdoor side of the mounting support member 6 is brought into contact with the indoor side wall of the existing frame 4 and positioned in the projection direction and attached.
Next, the existing frame-side waterproof tape 7 is attached across the existing frame 4 and the mounting auxiliary member 6, and the screw hiding waterproof tape 66 is attached across the existing frame 34 from the projection wall 60 of the mounting auxiliary member 6. - 特許庁
Next, the reform frame 3 is assembled. To assemble the remodeling frame 3, the upper frame 45, the lower frame 46, and the left and right vertical frames 47, 47 of the outer peripheral frame 2 are positioned around the new frame 1, which has been framed in advance, from the outer peripheral side while being positioned by the positioning part 54. The end faces of the frames 45, 46 are abutted against the inner peripheral side surfaces of the vertical frames 47, 47 via the sealing material 56, and the screws 103 inserted through the vertical frames 47 are screwed into the tapping holes 48 of the upper and lower frames 45, 46 from the side. framed by After that, the reinforcement member 24 is attached to the outer peripheral side surfaces of the vertical frames 47 , 47 and the upper frame 45 . The remodeling frame 3 may be assembled at the construction site of the refurbished sash, but it may be assembled at a factory and carried to the construction site.
Next, as shown in FIGS. 5 and 6, the remodeling frame 3 obtained 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 remodeling frame 3 is positioned in the prospective direction so that the indoor end (the indoor end of the outer peripheral frame 2 ) 64 coincides with the indoor end of the mounting support member 6 . In addition, the cover piece 50 of the lower frame 71 of the remodeling frame 3 is once removed, and the height of the gap adjusting component 72 is adjusted according to 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. After that, the reforming frame 3 is fixed to the frame with screws 52 from the inner peripheral side inside the room. Thereafter, the remodeling frame side waterproof tape 8 is attached across the mounting auxiliary member 6 and the remodeling frame 3. - 特許庁
After that, the resin frame 27 is attached from the indoor side.

Figures 25 and 26 show a modification of the modified sash of the first embodiment, which is applied to a bathroom window. Differences from the window of a normal living room (see FIGS. 1 and 2) will be described below.
First, the screw concealing waterproof tape 66 is extended to the outer peripheral side, and its outer peripheral side end portion is adhered to the frame (frame 34). Next, a remodeling frame side waterproof tape 104 is continuously provided on four circumferences across 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 front end of the tab portion 74 of the resin frame 27 and the existing frame 34 with the angle-shaped decorative material 77, the sealing material 105 is used to seal the gap.
By doing so, the refurbished sash of this embodiment can prevent water from entering the frame from the bathroom side when water is splashed from the bathroom side.

As described above, the refurbished sash is constructed by enclosing the periphery of the new frame 1, which is framed on all four sides, with the outer peripheral frame 2, and integrating the new frame 1 and the outer peripheral frame 2, and the opening to which the existing frame 4 is attached. Since it is not necessary to process the existing frame 4 or attach a member to the inner peripheral side of the existing frame 4 by fixing the outer peripheral frame 2 to the frame 5 by fitting it from the outdoor side to 26, workability is good. By fixing the outer peripheral frame 2 to the frame 5 on the indoor side, workability is further improved.

Figure 9 shows a second embodiment of the retrofit sash of the invention. This refurbished sash is applied to a double sliding window as in the first embodiment, and differs in that the lower frame 32 of the existing frame 4 is provided with an angle 78 . The mounting support member 79 on the lower frame 32 side is a substantially strip-shaped component made of an aluminum profile. This attachment support member 79 has a breakable portion 80 provided on the lower surface of the outdoor side, and by breaking off the breakable portion 80, the estimated dimension can be adjusted. This mounting support member 79 is positioned in the prospective direction so that the indoor side end is a certain dimension A (specifically, 110 mm) from the outdoor side end of the existing frame 4, and the outdoor side part is positioned under the existing frame 4. It is overlaid on the angle 78 of the frame 32 and fixed to the frame 5 with screws 63 at the inner side of the room.

FIG. 10 shows a jig 81 that is used to position the mounting aid 79 in the prospective direction. This jig 81 is a plate-shaped member cut along the outer shape of the lower frame 71 of the reforming frame 3 , and has a contact portion 82 that contacts the outdoor side end of the lower frame 32 of the existing frame 4 . , a recess 83 for accommodating the mounting aid 79 is provided. As shown in FIGS. 10(a) and 10(b), the attachment support member 79 is accommodated in the recess 83, and the jig 81 is installed while the contact portion 82 is brought into contact with the outdoor end of the lower frame 32 of the existing frame 4. As shown in FIGS. is applied to the lower frame 32 of the existing frame 4 from above, so that the indoor end of the mounting auxiliary member 79 is positioned at a constant dimension A from the outdoor end of the lower frame 32 of the existing frame 4. .

In this way, the mounting auxiliary member 79 is positioned so that the indoor end thereof is within a certain dimension A from the outdoor end of the existing frame 4 and fixed to the frame 5, and the indoor end 64 of the renovation frame 3 and the mounting auxiliary member are positioned. By positioning and fixing the remodeling frame 3 to the building frame 5 so that the interior side end of the remodeling frame 79 is aligned, the cover piece 50 of the remodeling frame 3 and the exterior wall of the existing frame 4 are separated from each other in the same manner as in the first embodiment. The gap is sealed with airtight materials 58a and 58b.

FIG. 11 is a modified example of the modified sash of the second embodiment, showing a case where the estimated dimension B of the existing frame 4 is smaller than that 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 attachment support member 79 is attached so that the position of the indoor end of the existing frame 4 is a constant dimension A (specifically, 110 mm) from the outdoor end of the existing frame 4. The auxiliary mounting member 79 moves toward the interior of the room by the amount (10 mm) that the projected dimension B is reduced.
Conversely, if the estimated dimension B of the existing frame 4 is larger than that shown in FIG. 9, the auxiliary mounting member 79 moves to the outdoor side by that amount. When the mounting support material 79 is moved to the outdoor side, if the outdoor side end of the mounting support material 79 protrudes to the outdoor side from the indoor side wall of the existing frame 4, it is broken off by the breakable part 80 and attached. The nominal size of the auxiliary material 79 is reduced.

Figures 12 and 13 show a third embodiment of the retrofit sash of the invention. The modified sash of this embodiment has a substantially L-shaped cross section in which the upper frame 45 and the vertical frame 47 of the outer peripheral frame 2 are formed integrally with a portion 84 extending in the viewing direction and a cover piece 50 extending to the outer peripheral side on the outdoor side. It is made of wood. By integrally forming the upper frame 45 and the vertical frame 47 of the outer peripheral frame 2 in this way, the number of members can be reduced, and the time and labor required for assembling the reforming frame 3 can be saved.

Further, in the modified sash of this embodiment, as shown in FIG. That is, the reinforcing plate 25 is arranged at two positions, namely, the upper part and the lower part, on the outer peripheral side surface of the vertical frame 47 of the outer peripheral frame 2, at positions on the sides of the upper frame 45 and the lower frame 46 of the outer peripheral frame 2. The reinforcing plate 25 and the vertical frame 47 are fastened together to the upper frame 45 and the lower frame 46 by screwing the screw 103 penetrating the vertical frame 47 into the tapping hole 48 of the upper frame 45 and the lower frame 46 . A sealing material 56 is interposed between the longitudinal end surfaces of the upper frame 45 and the lower frame 46 and the inner peripheral side surface of the vertical frame 47 . The reinforcing plate 25 abuts against a cover piece 50 protruding toward the outer peripheral side of the vertical frame 47 at its outdoor end.
Thus, even when the reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 47 of the outer peripheral frame 2, the shojis 28 and 29 are similar to the case where the reinforcing plate 25 is provided on the outer peripheral side of the vertical frame 37 of the new frame 1. It is possible to prevent the vertical frame 47 from being deformed so as to expand to the outer peripheral side when the door is closed forcefully, and watertightness can be maintained.

Figures 15 and 16 show a fourth embodiment of the retrofit sash of the invention. In the refurbished sash of this embodiment, the existing frame 4 is a sash frame with shutters 85 attached. As shown in FIG. 15, the upper frame 31 of the existing frame is provided with a guide groove 86 that guides the upper part of the rain door 85, and the lower frame 32 of the existing frame 4 guides the lower part of the rain door 85. A rail 87 is provided so as to protrude to the outside of the room.

As in the first embodiment, the outer peripheral frame 2 of the reforming frame 3 includes a main member 49 in which an upper frame 45 and a vertical frame 47 extend in the prospective direction, and a cover piece detachably attached to the outdoor end of the main member 49. 50 , and the upper frame 45 has an auxiliary member 22 attached instead of the cover piece 50 .
