[0018] An upper rail 311C is attached to the lower surface of the upper slide portion 311B, and a lower rail 312C is attached to the upper surface of the lower slide portion 312B. The upper rail 311C and the lower rail 312C are attached so as to be positioned between the slide regulating portion 313B and the left vertical frame member 315. The upper slide portion 311B, the lower slide portion 312B, the slide regulating portion 313B, and the left vertical frame member 315 constitute an inner window frame portion 317 that supports the functional inner window shutter 32. The inner window frame portion 317, the upper rail 311C, and the lower rail 312C constitute a slide portion 318 that slides the functional inner window shutter 32 along the X-axis direction between a closed position where the wall opening 115 is closed as shown in FIG. 2 and an open position where the wall opening 115 is opened by more than half as shown in FIG. 3.

[0019] The functional inner window shutter 32 includes a dimming glass 321 and an inner window frame body 322 attached to the outer peripheral portion of the dimming glass 321. The dimming glass 321 includes two sheets of glass and a dimming film composed of, for example, liquid crystal sandwiched between these glasses, and has a dimming function of adjusting the light transmittance of the dimming film by the power supplied through the wiring 323. The light whose transmittance is adjusted by the dimming glass 321 includes at least one of visible light and ultraviolet light. The inner window frame body 322 includes an upper inner window frame 322A, a lower inner window frame 322B, a right inner window frame 322C, and a left inner window frame 322D, each formed of wood. A concave portion recessed downward is provided on the upper surface of the upper inner window frame 322A. An upper guide 322A1 into which the upper rail 311C of the inner frame body portion 31 fits is provided in this concave portion. Door wheels 322B1 that travel on the lower rail 312C of the inner frame body portion 31 are provided at a plurality of positions along the X-axis direction in the lower inner window frame 322B. A stopper 322C1 is provided on the outdoor side surface of the right inner window frame 322C. The stopper 322C1 is formed so as not to contact the inner frame body portion 31 when the functional inner window shutter 32 is in the closed position, and to contact the left molding member 314 in a state where the left inner window frame 322D is separated from the left vertical frame member 315 when the functional inner window shutter 32 is in the open position.

[0020] The wiring 323 comprises a flexible cable 323A and a round cable 323B. As shown in Figures 4 and 5, one end of the flexible cable 323A is fixed to the center of the X-axis direction in the recess of the inner window upper frame 322A via a mounting bracket 323C, with the indoor end of the flexible cable 323A located on the outdoor side of the indoor surface of the inner window upper frame 322A, and the outdoor end not in contact with the upper sliding part 311B and the upper rail 311C. The glass-side terminal 321A of the dimmable glass 321 is connected to the cable-side terminal 323A1 provided on one end of the flexible cable 323A. The other end of the flexible cable 323A is fixed to the upper and left side of the wall opening 115 in the inner wall 12 when viewed from the indoor side, via a mounting bracket 323D. In this way, by fixing both ends of the flexible cable 323A to the upper frame 322A of the inner window and the inner wall 12, the flexible cable 323A deforms as shown in Figure 5 as the functional inner window sash 32 slides. One end of a round cable 323B is electrically connected to the other end of the flexible cable 323A. The other end of the round cable 323B is connected to a power source and is configured to supply power from the power source to the dimmable glass 321.

[0021] The insulation panel 4 comprises an insulation material 41 and a decorative panel 42 attached to one side of the insulation material 41, and is configured such that its thickness is thinner than or equal to the protrusion dimensions of the lower member 312 and the right vertical member 313 from the inner wall 12, that is, the maximum protrusion dimension of the inner frame body 31. The insulation panel 4 is attached to the inner wall 12 so as to surround the inner frame body 31 of the inner window 3 via double-sided tape (not shown) provided on the other side of the insulation material 41. Specifically, the insulation panel 4 provided above the upper member 311 is attached such that the lower end of the panel is positioned above the upper end of the mounting bracket 323D. The insulation panel 4 installed on the underside of the lower member 312 has its upper end edge in contact with the lower member 312, the insulation panel 4 installed on the right side of the right vertical member 313 has its left end edge in contact with the right vertical member 313, and the insulation panel 4 installed on the left side of the left vertical frame member 315 has its right end edge in contact with the left vertical frame member 315.

[0022] After the interior window 3 and insulation panel 4 are installed on the interior side of the wall 1, the furniture 9 shown in Figure 6 is placed there. The furniture 9 is made of wood, for example, and comprises a first row 91, a second row 92, a third row 93, a fourth row 94, and a fifth row 95. The first row 91, second row 92, third row 93, fourth row 94, and fifth row 95 are arranged in this order from right to left when viewed from the interior side. The first row section 91, the second row section 92, and the fourth row section 94 each include a shelf with a lower door 9A, two open shelves 9B located above the lower shelf with a door 9A, and a first upper shelf with a door 9C located above the upper open shelf 9B. The third row section 93 comprises a bench 9D located between the left and right lower shelves 9A with doors, and a second upper shelf 9E located between the left and right first upper shelves 9C with doors. A rectangular opening 96 for exposing an inner window sash is provided in the right center in the vertical direction of the third row section 93. The opening 96 for exposing an inner window sash is composed of a lower back plate 931 that constitutes the bench 9D, a bottom plate 932 (see Figure 1) that constitutes the second upper shelf 9E with doors, and a pair of support columns 97 that support the lower back plate 931 and the bottom plate 932. The fifth column section 95 is equipped with a decorative panel 9F. The decorative panel 9F has approximately the same thickness as the back panels 911, 921, 941 of the lower shelf with door 9A, the open shelf 9B, and the first upper shelf with door 9C that constitute the first, second, and fourth columns 91, 92, and 94, as well as the upper back panel 933 of the second upper shelf with door 9E that constitutes the third column section 93, and is provided so that its interior surface lies approximately flush with the interior surfaces of each back panel 911, 921, 941 and the upper back panel 933. In the following description, each back panel 911, 921, 941, the lower back panel 931, the upper back panel 933, the decorative panel 9F, and the support columns 97 that support them may be collectively referred to as the back panel section 98.

[0023] As shown in Figures 1 to 3, the furniture 9 is positioned such that the opening 96 for exposing the inner window sash exposes the functional inner window sash 32 in the closed position to the interior side, and the back panel portion 98 abuts against the interior end faces of the lower member 312, right vertical member 313, and left vertical frame member 315 that constitute the inner frame body 31. In this simple manner, by positioning the furniture 9 so that it abuts against the inner frame body 31, a gap S is formed between the inner wall 12, insulation panel 4, upper member 311 and the back panel portion 98. Note that the furniture 9 only needs to be positioned so that a gap S is formed, and it may be positioned so that it does not abut against the interior end faces of the lower member 312, right vertical member 313, and left vertical frame member 315. Of the gap S, the portion to the left of the functional inner window sash 32 in the closed position and to the right of the left vertical frame member 315 functions as an inner window sash gap S1 for pulling the functional inner window sash 32 into the open position. Of the gap S, the portion above the movable area of ​​the functional inner window sash 32 and below the insulation panel 4 located above the inner window 3 constitutes a wiring gap S2 in which the wiring 323 is placed. The round cable 323B is extended through the wiring gap S2, for example to the right when viewed from the interior side, and connected to the power supply.

[0024] Next, the method for renovating wall 1 will be explained. Note that the renovation procedure is not limited to the procedure shown below; any procedure is acceptable as long as the interior window 3, insulation panel 4, and furniture 9 are installed, as shown in Figures 1 to 3. First, the mounting bracket 323D is attached to the inner wall 12 of the frame 11 to which the outer window 2 is installed. Next, the inner window 3, to which one end of the flexible cable 323A is fixed via the mounting bracket 323C, is installed in the wall opening 115. After this, the other end of the flexible cable 323A, which is connected to the round cable 323B, is fixed to the mounting bracket 323D. Then, the round cable 323B is extended to the right when viewed from the inside of the room, along the inner wall 12, at a position below the upper end of the mounting bracket 323D, that is, extended to the right at a position where a wiring gap S2 is formed, and connected to the power supply. Alternatively, as will be described later, the round cable 323B may be connected to the power supply after the furniture 9 has been placed. Next, the insulation panel 4 is attached to the interior wall 12 so as to surround the inner frame portion 31 of the interior window 3. Then, the functional interior window sash 32, which is in the closed position of the opening 96 for exposing the interior window sash, is exposed to the interior side, and the furniture 9 is arranged so that a gap S1 for the interior window sash and a gap S2 for wiring are formed.

[0025] According to the above embodiment, the furniture 9 is arranged so that a wiring gap S2 is formed. Therefore, it is not necessary to form holes for inserting wiring in the structural frame 11 of the wall 1, and the interior window 3 equipped with dimmable glass 321 can be easily installed. Furthermore, since the wiring 323 is hidden by the furniture 9, a decrease in the aesthetic appearance of the room can be suppressed. The interior window 3 is equipped with dimmable glass 321. This allows the amount of natural light entering the room to be adjusted to the desired level. An insulation panel 4 is attached to the interior wall 12. This improves the insulation of the room. The furniture 9 is positioned so that a gap S1 for the inner window sash is formed. By sliding the functional inner window sash 32 to the open position and opening the wall opening 115 more than halfway, maintenance of the outer window 2 and operation of the outer window 2's handle 23 can be easily performed, and ventilation through the outer window 2 and inner window 3 is improved. In addition, the functional inner window sash 32 in the open position is hidden by the furniture 9, which helps to prevent a decrease in the aesthetic appearance of the room. The wiring 323 is connected to the upper side of the functional inner window sash 32, that is, to the side perpendicular to the left-right direction which is the sliding direction of the functional inner window sash 32, and a wiring gap S2 is formed on the upper side relative to the inner window 3. As a result, the wiring 323 is no longer present on the side of the functional inner window sash 32 in the sliding direction, thus suppressing problems such as the wiring 323 getting caught when the functional inner window sash 32 slides. The furniture 9 is provided with an opening 96 for exposing the inner window sash. As a result, the area around the functional inner window sash 32 in the closed position is surrounded by the furniture 9, which enhances the sense of unity between the inner window 3 and the furniture 9. As furniture 9, a configuration including bench 9D is applied. Therefore, an interior space with bench 9D can be provided.

[0026] [Differentiation] Functional interior window sashes may include a blind sandwiched between two panes of glass, and may also include double-glazed glass with a built-in blind that adjusts the light-blocking rate by electrically adjusting the angle of the multiple slats that make up the blind. The electrically operated functional component may be a locking mechanism that locks the interior window sash, or an opening and closing mechanism that opens and closes the interior window sash. It is not necessary to install the insulation panel 4 on the interior wall 12. The sliding direction of the functional inner window sash 32 may be in the Y-axis direction (up and down direction). The inner window may be a sliding window configured so that a pair of sashes can be opened and closed in a sliding manner, or it may be a casement window or a fixed window, in which case it is not necessary to provide a gap for the inner window sash. The outer window may be a sliding window or a fixed window. For example, without providing the left vertical frame member 315, the portion to the left of the functional inner window sash 32 at the closed position in the gap S may be made to function as a gap for the inner window sash, the wiring 323 may be connected to the left side of the functional inner window sash 32 as viewed from the interior side, that is, the side in which the functional inner window sash 32 slides, and the round cable 323B may be extended to the left and connected to the power supply. In this case, by composing the furniture 9 with, for example, only the fourth row section 94 and the fifth row section 95, the opening 96 for exposing the inner window sash may be omitted, and the area around the functional inner window sash 32 at the closed position may not be surrounded by the furniture 9. Furniture 9 does not necessarily have to include bench 9D; instead of bench 9D, or along with bench 9D, a desk, drawers, etc., may be included. Furniture 9 may consist only of decorative panels.
