The upper frame 21 and the vertical frames 23 are formed hollow with a rectangular cross section.
The reform frame 13 has a door stop piece 47 protruding inward on the interior side of the door 14, and an airtight material 26 attached to the door stop piece 47 abuts against the interior side of the door 14.

As shown in Figures 2 and 3, the door 14 is attached to the right-hand vertical frame 23 when viewed from outside the room by a hinge 27, and is designed to rotate toward the outside of the room around the hinge 27 as a fulcrum to open.

As shown in Figures 1 to 3, the frame 1 has a horizontal frame 1b attached to the outdoor side surface of the upper frame 21 of the reform frame 13 and arranged along the longitudinal direction of the upper frame 21, and left and right vertical frames 1a, 1a attached to the outdoor side surfaces of the left and right vertical frames 23, 23 of the reform frame 13 and arranged along the longitudinal direction of the vertical frames 23, 23.
As shown in Figure 1, the vertical frame 1a protrudes further outward than the horizontal frame 1b, and a notch (not shown) is provided on the inner circumferential surface of the upper end of the vertical frame 1a, and as shown in Figure 3, both longitudinal ends of the horizontal frame 1b are inserted into the vertical frame 1a through the notch. A resin cap 28 is attached to the upper end of the vertical frame 1a.
As shown in Figures 1 and 2, the frame 1 covers the outer periphery of the upper frame 21 and the left and right vertical frames 23, 23 of the reform frame 13 from the outside of the room, and the upper frame 17 and the left and right vertical frames 19, 19 of the existing frame 12 are hidden by the frame 1.

As shown in FIG. 4, the vertical frame 1a is composed of two members, a front side member 2 and a rear side member 3, both of which are made of extruded aluminum alloy material.
The facing-side member 2 is formed with an approximately U-shaped cross section by an inner facing wall 29, a facing wall 4, and an outer facing wall 30. On the inner side of the facing wall 4, the frame-side end of the inner facing wall 29 has a mounting portion 5 with an approximately U-shaped cross section that is open on the side opposite the frame. As shown in Figure 2, the mounting portion 5 abuts against the outdoor side surface of the vertical frame 23 of the renovation frame 13 and is fastened with screws 31 from the outdoor side. Then, a batten 32 is engaged and attached to the mounting portion 5 from the outdoor side, with the heads of the screws 31 hidden by the batten 32.
As shown in Figure 4, the facing wall 4 is slightly inclined and curved so that it bulges toward the opposite side of the body as it approaches the outer periphery. An attachment portion 6 to which the facing-side member 3 is attached is provided on the outer periphery of the facing wall 4. More specifically, the attachment portion 6 has a shoulder 33 recessed toward the body at the outer periphery end of the facing wall 4. A projection 34 protruding toward the outer periphery is formed on the facing portion 33a of the shoulder 33, and a projection 35 protruding toward the opposite side of the body is formed on the facing portion 33b of the shoulder 33. The projection 35 of the facing portion 33b has a hook 36 at its tip that protrudes toward the inner periphery.
A plurality of break grooves 37 are provided at intervals in the left-right direction on the back surface (body side surface) of the visible wall 4. A plurality of break grooves 37 are also provided at intervals in the projection direction on the outer peripheral side surface of the outer peripheral-side visible wall 30.
The visible-side member 2 has a decorative sheet with a printed wood grain pattern or the like attached to the inner peripheral side surface of the inner peripheral-side visible wall 29 and the opposite side surface of the visible wall 4 to the frame (the dashed line 38 in the drawing indicates the area where the decorative sheet is attached), and the outer peripheral edge of the decorative sheet is folded toward the frame and extends to a position where it abuts on the protrusion 34 of the projected portion 33a of the shoulder portion 33. In addition, a decorative sheet is attached to the inner peripheral side surface of the mounting portion 5.

The projection-side member 3 is formed with a generally L-shaped cross section, consisting of a facing wall 10 located on the opposite side of the frame and a facing wall 8 extending from the outer periphery of the facing wall 10 toward the frame. An attachment portion 7 for the projection-side member 2 is formed on the frame side of the facing wall 10. The attachment portion 7 consists of two claws 39, 40 spaced apart in the inner and outer periphery and protruding toward the frame. Each claw 39, 40 engages with two protrusions 34, 35 on the attachment portion 6 of the projection-side member 2, respectively, allowing the projection-side member 3 to be attached to the projection-side member 2 without rattle. The inner claw 39 has an inclined portion 39a at its tip end that slopes toward the outer periphery, and the outer claw 40 has an inclined portion 40a at its tip end that slopes toward the inner periphery.
The projection wall 8 has a plurality of break grooves 9 (length adjustment parts) provided at intervals in the projection direction on the back surface (inner peripheral side surface), and the length in the projection direction can be adjusted by breaking it at any of the break grooves 9.
The concealed side member 3 has a decorative sheet attached from the opposite side of the frame of the concealed wall 10 to the outer peripheral side of the concealed wall 8.

As shown in Figures 5(a) and (b), when the two claws 39, 40 of the mounting portion 7 of the prospective side member 3 are inserted between the protrusions 34, 35 of the mounting base 6 of the prospective side member 2 and the prospective wall 10 is pushed from the opposite side of the frame toward the frame, as shown in Figure 5(c), the two claws 39, 40 of the mounting portion 7 resiliently engage with the protrusions 34, 35 of the mounting base 6, thereby stably attaching the prospective side member 3 to the prospective side member 2. The inclined portions 39a, 40a at the tips of the claws 39, 40 make it easy to fit the mounting portion 7 of the prospective side member 3 into the mounting base 6 of the prospective side member 2 from the opposite side of the frame.

As shown in Figure 4(a), when installed, the visible wall 10 of the visible side member 3 is positioned toward the main body relative to the visible wall 4 of the visible side member 2, and a step is formed between the two visible walls 10, 4.
The inner edge 10a of the visible wall 10 of the prospective side member 3 is not covered with a decorative sheet, and the color of the aluminum is exposed. However, if the visible wall 10 of the prospective side member 3 and the visible wall 4 of the visible side member 2 were flush with each other, the edge 10a would be visible depending on the viewing direction, which would be undesirable.
As described above, in the vertical frame 1a of this embodiment, the visible wall 10 of the visible side member 3 is positioned shifted toward the main body side of the visible wall 4 of the visible side member 2, so that the edge 10a is hidden opposite the visible portion 33a of the shoulder portion 33 of the visible side member 2 to which the decorative sheet is attached, and therefore the edge 10a is not noticeable when viewed from the outside, thereby improving the design.

As shown in Figure 1, horizontal frame 1b has the same structure as vertical frame 1a described above, with only a slight difference in cross-sectional shape. That is, horizontal frame 1b is composed of two components: a front-side member 2 and a recessed-side member 3. The front-side member 2 is attached by abutting the mounting portion 5 on its inner periphery against the exterior surface of the upper frame 21 of the renovation frame 13 and screwing it in with screws 31 from the exterior. The recessed-side member 3 is attached by fitting the mounting portion 7 on the frame side of the front wall 10 into the mounting portion 6 of the front-side member 2 from the opposite frame side (exterior side).

As shown in Figures 1 and 2, the internal cover 16 has horizontal cover material 16b arranged along the longitudinal direction of the upper frame 21 on the indoor side of the upper frame 21 of the reform frame 13, and vertical cover materials 16a, 16a arranged along the longitudinal direction of the vertical frames 23, 23 on the indoor sides of the left and right vertical frames 23, 23 of the reform frame 13, with the horizontal cover material 16b hiding the upper frame 17 of the existing frame 12 and the vertical cover materials 16b, 16b hiding the vertical frames 19, 19 of the existing frame 12.
The horizontal cover material 16b and the vertical cover material 16a are made of aluminum extrusions having the same cross-sectional shape, which is approximately L-shaped, and have a concealed wall 41 and facing walls 42, 42, and the concealed wall 41 and facing walls 42, 42 are each provided with a breaking groove 43 so that the length can be adjusted by breaking it at the breaking groove 43.
After adjusting the lengths of the projection wall 41 and the facing walls 42, 42, the horizontal cover material 16b and the vertical cover material 16a are attached to the body 20 by abutting the tip of the projection wall 41 against the interior side of the renovation frame 13 and the tips of the facing walls 42, 42 against the inner side of the body 20 with screws 44 from the inner side.

Next, the construction procedure of this opening device will be explained.
First, the reform frame 13 is placed on the inner periphery of the existing frame 12 from either the outside or inside of the room, and the reform frame 13 is fixed with screws 24, 25 from the inner periphery.
Next, the horizontal frame 1b and the vertical frames 1a, 1a are attached in order. To attach the horizontal frame 1b, first, as shown in Figure 7(a), the mounting portion 5 of the front-side member 2 is screwed to the exterior surface of the upper frame 21 of the reform frame 13 with screws 31 from the exterior side. Then, as shown in the same figure, the front-side member 3 is held upside down, the front wall 10 is abutted against the exterior wall 45, and the front wall 8 is cut at the break groove 9 one step below the same line as the front wall 4 of the front-side member 2.
Next, as shown in Figure 7(b), while visually checking the attached portion 6 of the visible side member 2, the attachment portion 7 of the visible side member 3 is placed opposite the attached portion 6 on the opposite side of the structure, and the visible wall 10 of the visible side member 3 is pushed toward the structure, and as shown in Figure 7(c), the attachment portion 7 engages with the attached portion 6 and the visible side member 3 is attached to the visible side member 2.
Thereafter, as shown in FIG. 7( c ), the gap between the frame-side end of the projection wall 8 of the projection-side member 3 and the outer wall 45 is sealed from the outer periphery with a sealing material 46 .
Next, the vertical frames 1a, 1a are attached in the same manner as the horizontal frame 1b. To attach the vertical frame 1a, first, as shown in Figure 6(a), the mounting portion 5 of the front-side member 2 is screwed to the exterior side surface of the vertical frame 23 of the renovation frame 13 with screws 31 from the exterior side. Then, as shown in the same figure, the front-side member 3 is held upside down, the front wall 10 is abutted against the exterior wall 45, and the front wall 8 is cut at the break groove 9 one step below the same line as the front wall 4 of the front-side member 2.
Next, as shown in Figure 6(b), while visually checking the attached portion 6 of the visible side member 2, the attachment portion 7 of the visible side member 3 is placed opposite the attached portion 6 on the opposite side of the structure, and the visible wall 10 of the visible side member 3 is pushed toward the structure, and as shown in Figure 6(c), the attachment portion 7 engages with the attached portion 6 and the visible side member 3 is attached to the visible side member 2.
Thereafter, as shown in FIG. 6( c ), the gap between the frame-side end of the projection wall 8 of the projection-side member 3 and the outer wall 45 is sealed from the outer periphery with a sealing material 46 .
Next, the inner cover 16 is attached to the inside of the room.
Finally, the door 14 is attached to the reform frame 13.

Figure 8 shows an example of a variation of the vertical frame 1a. Figure 8(a) is the same as that described above, while Figure 8(b) shows the facing wall 10 of the recessed-side member 3 extending outward from the attached portion 6 of the recessed-side member 2. The facing wall 10 of the recessed-side member 3 is slightly inclined toward the frame as it approaches the outer periphery, and has a curved shape, symmetrical to the facing wall 4 of the recessed-side member 2. The facing wall 10 of the recessed-side member 3 is not limited to this shape, and can also be shaped to protrude away from the frame as it approaches the outer periphery.
In this way, the design of the vertical frame 1a can be changed simply by replacing the projected side member 3. The same applies to the horizontal frame 1b.
