Description

  The present invention relates to an additional window arranged in a window frame in which an existing window is installed.

  The following structure is known as one example of a conventional anti-condensation structure for an existing window glass. A dew condensation prevention panel member is attached to the inside (inside air side) surface of the existing window glass arranged in the window frame via a double-sided adhesive tape. The dew condensation prevention panel member is a plate-like body made of a polycarbonate material excellent in transparency, weather resistance, and heat resistance. And between the panel surface parts which the dew condensation prevention panel mutually opposes is divided | segmented at equal intervals in the fixed direction via the partition part, and the dew condensation prevention panel has a some hollow part. With this structure, outside air is blocked from entering the room by the double air layer formed by the air layer of the existing window glass and the dew condensation prevention panel and the air layer in the hollow portion of the dew condensation prevention panel. And it prevents that dew condensation generate | occur | produces in the existing window glass from the temperature difference of outside air and inside air (for example, refer patent document 1).

  The following apparatus is known as an example of the conventional dew condensation prevention apparatus for the existing window glass. A square frame-like window frame member is constructed on the wall surface of the building, and an aluminum sash frame and a pair of window glasses are attached to the inside of the window frame member. A holding member made of an elongate bendable sponge material is adhered to the inner side surface of the window frame member. For example, an adhesive layer made of a double-sided pressure-sensitive adhesive tape is formed on the side surface of the holding member. For example, a sheet material made of a synthetic resin is stretched on the holding member using an adhesive layer. With this structure, a substantially sealed air layer is formed between the window glass and the sheet material, and condensation is prevented from occurring in the window glass due to the presence of the air layer (for example, see Patent Document 2). .)

The following retrofit kit is known as an example of a conventional retrofit kit for forming a double window for an existing window glass. In the building, a sash window made of a pair of window glass and an aluminum sash is arranged, and, for example, a wooden indoor window frame is arranged on the indoor side of the sash window. A double window forming retrofit kit is installed directly above the upper frame of the indoor window frame. The double window forming retrofit kit includes a winding device having a winding roll, a non-air-permeable and light-shielding film having an upper end fixed to the winding roll, and a locking member fixed to the lower end of the film. It is comprised by. The locking member is engaged with the lower frame of the indoor window frame so that the window frame and the film are in close contact with each other, and the existing window glass and film form a double window structure. With this structure, it is possible to prevent condensation from occurring on the existing window glass and to save energy for cooling and heating (see, for example, Patent Document 3).
JP 2004-293280 A (page 5-6, Fig. 1-4) JP-A-7-269244 (page 2-3, Fig. 1-4) Japanese Unexamined Patent Publication No. 2000-213247 (page 6-8, FIGS. 1, 3, and 9)

  As described above, in the conventional dew condensation prevention structure, a dew condensation prevention panel member that is the same as or slightly smaller than the size of an existing window glass is prepared, and the dew condensation prevention panel is attached to the existing window glass with a double-sided adhesive tape. Except for the time when condensation is likely to occur, the condensation prevention panel member is unnecessary and must be stored in a closet or the like. At this time, since the dew condensation prevention panel member is the same size or slightly smaller than the existing window glass, it is difficult to carry the dew condensation prevention panel member, and it is difficult to secure a storage space for the dew condensation prevention panel member. There is.

  Furthermore, when the existing window glass is larger than the person who installs the dew condensation prevention panel member, the dew condensation prevention panel member also becomes larger, and it is difficult to perform installation work on the existing window glass by one person. There is a problem.

  Further, in order to realize the opening / closing operation of the existing window glass after the dew condensation prevention panel member is installed, it is necessary to install the dew condensation prevention panel member in a narrow space between the pair of existing window glasses. At this time, there is a problem that it is difficult to install the condensation prevention panel member on the existing window glass while securing a space layer between the existing window glass and the condensation prevention panel member.

  Furthermore, the size of the existing window glass varies depending on the size of the building, the room, and the design requirements. Therefore, in order to prevent dew condensation on the existing window glass, it is necessary to prepare a dew condensation prevention panel member suitable for its size, and there is a problem that it is difficult to install easily due to poor mass production.

  Further, in the conventional dew condensation prevention device, the holding member is adhered to the inner side surface of the window frame member in an enclosed state, and an adhesive layer made of, for example, a double-sided adhesive tape is formed on the holding member side surface. For example, a sheet material made of a synthetic resin is stretched on the holding member using an adhesive layer. Therefore, there is a problem that the pair of window glasses cannot be opened and closed when one sheet material is stretched over the entire inside of the window frame member. On the other hand, in order to open and close the window glass, it is necessary to remove the installed sheet material, and further, after the window glass opening and closing operation, it is necessary to stretch the sheet material again using the holding member, There is a problem that the installation work and the removal work of the materials are troublesome. Moreover, there is a problem that the work of maintaining the airtightness of the air layer between the window glass and the sheet material is troublesome each time.

  Furthermore, when the existing window glass is larger than the person who installs the holding member and the sheet material, there is a problem that it is difficult for one person to perform the installation work on the existing window glass. Moreover, there exists a problem that the operation | work which installs a sheet | seat material is difficult, maintaining the airtightness of the air layer between a window glass and a sheet | seat material.

  In the simple double window forming retrofit kit, the double window forming retrofit kit is installed immediately above the upper frame of the indoor window frame. And the latching member fixed to the lower end of a film is engaged using the lower frame of an indoor side window frame. Therefore, it is easy to ensure the adhesion between the upper and lower frames of the indoor side window frame and the film, but it is difficult to ensure the adhesion between the left and right frames of the window frame and the film. There is a problem that it is difficult to ensure the airtightness of the air layer. On the other hand, when a double-sided adhesive tape is placed on the side of the indoor window frame to improve the adhesion between the window frame and the film, the film is wound up in the double window forming retrofit kit, but remains on the film. There is a problem that the film sticks due to the adhesive force of the double-sided adhesive tape.

  Further, the retrofit kit for forming a double window is installed on a wall or the like on the indoor side of the building using the window frame itself. Therefore, the distance between the window glass and the film is determined by the existing indoor side window frame, and the distance between the window glass and the film is changed to the most suitable distance according to the area and season where it is installed. There is a problem that cannot be done.

FIG. 5B is a diagram for explaining a usage state of the additional window according to the present embodiment.

  As shown in FIG. 1 (A), the extension window 1 is installed in a window frame 4 of an opening region 3 formed in a structure 2 such as a building, a condominium, an apartment, or a house. It is located between the existing windows 7 and 8. The window frame 4 is made of, for example, wood, and is attached to the structure 2 on the indoor side of the opening region 3. On the other hand, for example, aluminum sash frames 5 and 6 are attached to the structure 2 outside the opening region 3. A pair of existing windows 7 and 8 are attached to the aluminum sash frames 5 and 6 so as to be freely opened and closed. The window frame 4 may be already attached to the structure 2 or may be newly attached to the existing window frame 4 or the structure 2.

  As shown in FIGS. 1A and 1B, the expansion window 1 is installed in close contact with the window frame 4 so that the air layer between the expansion window 1 and the existing windows 7 and 8 is substantially airtight. Has been. Although details will be described later, for example, the panel suspension plate 10 of the additional window 1 is fixed to the upper frame 9 of the window frame 4 with double-sided adhesive tape or the like, and is attached to the lower frame 11, the left frame 12, and the right frame 13 of the window frame 4.

The panel suspension plate 10 is fixed to the window frame 4 with a double-sided adhesive tape or the like, so that the window frame 4 can be prevented from being damaged by nails, screws or the like.

  As shown in FIG. 2 (A), the expansion window 1 (see FIG. 1 (A)) has a plurality of panels 15, 16, 17, 18, 19 connected by connecting sheets 20, 21, 22, 23. It consists of Since the panels 15 to 19 are made of, for example, a polycarbonate material, they are excellent in lightness, daylighting, durability, impact resistance, and the like. And the panels 15-19 are the structures which have a hollow part between an indoor side and an outdoor side (existing window side), and the panels 15-19 itself prevent the fluidity | liquidity of air, and existing windows 7, 8 ( The dew-proofing property in FIG. 1A and the heat insulating property in the opening region 3 (see FIG. 1A) can be improved.

  The panels 15 to 19 are connected by connecting sheets 20 to 23 on the side surface on the indoor side and the side surface on the outdoor side, and are substantially used as an integrated plate-like body when used as the additional window 1. Here, the term “integrated” refers to a state in which the individual panels 15 to 19 are separated from each other, but are connected so as to be used as an additional window 1 as an airtight structure. And the connection sheets 20-23 consist of a resin sheet, a film, etc. excellent in daylighting property, air permeability, and a softness | flexibility, and what has adhesiveness on one side is used. The magnitude | size of the connection sheets 20-23 should just be a magnitude | size which can maintain at least the adjacent panels 15-19 in a connection state. In the present embodiment, the size of the connection sheets 20 to 23 is substantially the same as the size of the two adjacent panels 15 to 19, and the indoor side and the outdoor side of the panels 15 to 19 are used. Is covered with a connection sheet.

  If it demonstrates using the panel 17 concretely, the panel 17 will be arrange | positioned so that the panel 16 and the panel 18 may be adjoined. The panel 16 and the panel 17 are connected by a connection sheet 21 on the side surface on the outdoor side. On the other hand, the panel 17 and the panel 18 are connected by a connection sheet 22 on the side surface on the indoor side. That is, the panel 17 is connected to the panels 16 and 18 by using the side surfaces on the indoor side and the outdoor side.

  Moreover, as shown by a circle, the openings 24, 25, 26, and 27 of the connection sheets 20 to 23 are alternately arranged on the side surface on the indoor side or the side surface on the outdoor side. However, when the opening 25 between the connection sheets 20 and 22 is disposed on the side surface on the indoor side, the side surface on the outdoor side is covered with the connection sheet 21. With this structure, the panels 15 to 19 are substantially formed as a single plate-like body, and the air flow between the panels 15 to 19 is suppressed to realize an airtight structure. Note that the panels 15 to 19 may not have a hollow structure.

  As shown in FIG. 2 (B), the eight panels 15 to 19 and 28 to 30 constituting the additional window 1 are connected to form a single plate-like body by connecting sheets 20 to 23 and 31 to 35. Has been. As described above, in the connection sheets 20 to 23 and 31 to 35, a plurality of openings 24 to 27, 36, and 37 are alternately formed on the indoor side or the outdoor side. With this structure, the eight panels 15 to 19 and 28 to 30 are folded in a bellows state. At this time, the openings 24 to 27, 36 and 37 are formed by providing a slight gap between the panels 15 to 19 and 28 to 30. And by providing the said clearance gap, foldability is improved and durability of the connection sheet in a folding area | region is also improved.

  Furthermore, in a season where the dew proofing of the existing windows 7 and 8 and the heat insulation of the opening region 3 of the structure 2 (see FIG. 1A) are not considered, the additional window 1 is stored in a closet or the like in a folded state. Thus, the storage space can be used efficiently. Moreover, since the installation work to the window frame 4, the removal work from the window frame 4, a carrying work, etc. can be performed in the state which extended window 1 was folded, it is excellent in workability | operativity.

  As shown in FIG. 1A, in the present embodiment, the case where the additional window 1 is configured using eight panels has been described, but the present invention is not limited to this case. The design of the number of panels can be arbitrarily changed according to the size of the window frame in which the additional windows are installed. Then, the size of the extension window can be adjusted by the number of panels, and an extension window excellent in versatility can be realized because it can easily cope with a window frame of any size.

  As shown in FIG. 3A, the panel 16 and the panel 17 are connected by the connection sheet 21 in a state where a slight gap 38 is provided between the panel 16 and the panel 17. As described above, providing the gap 38 improves the durability of the connection sheet 21 in the folded region. On the other hand, the opening 25 indicated by a circle is covered with an extension region 39 of the connection sheet 22 connected to the panel 17. With this structure, the airtightness of the additional window 1 itself is further improved, and the air flow can be suppressed at the width of the panels 16 and 17 in the opening 25, and the above-described dewproofing and heat insulating properties are improved. Although not shown, when the extension region 39 of the connection sheet 22 and the connection sheet 20 are appropriately fastened with a joint fitting such as a clip, the airtightness of the additional window 1 itself is more reliably improved. But you can.

  As shown in FIG. 3B, the gap 38 (see FIG. 3A) between the panel 16 and the panel 17 may be filled with the resin sheet 40. The resin sheet 40 is a material excellent in elasticity and may be attached to one of the side surfaces of the panels 16 and 17. And although mentioned later for details, when using as the expansion window 1, air is inject | poured in the hollow tube 14 (refer FIG. 1 (A)), and the panels 16 and 17 are pressed. Due to the pressing force, the resin sheet 40 and the panels 16 and 17 are in close contact with each other, and the airtightness of the additional window 1 itself is further improved. With this structure, also in the panels 15 to 19 and 28 to 30 (see FIG. 2 (B)), the flow of air can be suppressed with the widths of the panels 16 and 17, and the above-described dew prevention and heat insulation are improved.

  In addition, the structure which covers the opening part 25 with the connection sheet | seat 22 is demonstrated using FIG. 3 (A), and the structure which fills the clearance gap 38 between the panels 16 and 17 with the resin sheet 40 using FIG. 3 (B). However, the combination of both structures may further improve the airtightness of the additional window 1 itself.

  As shown in FIG. 4A, hollow tube mounting frames 41 and 42 are arranged on both sides of the panel 17, for example, on the side surfaces of the window frame 4 facing the left and right frames 12 and 13 (see FIG. 1B). Has been. The hollow tube attachment frames 41 and 42 are, for example, H-shaped, and the panel 17 is fitted in one concave portion, and the hollow tube 14 is disposed in the other concave portion. The hollow tube mounting frames 41 and 42 serve as guide rails for the hollow tube 14 to be always positioned on the side surface of the panel 17. In addition, the hollow tube attachment frame is arrange | positioned at each panel 15-19, 28, 29 (refer FIG. 2 (B)) which comprises the additional window 1, respectively. The hollow tube mounting frame is formed independently for each of the panels 15 to 19, 28, and 29.

  As shown in FIG. 4B, for example, the panel 30 positioned at the lower end of the additional window 1 is provided with hollow tube mounting frames 43 and 44 on both ends thereof, for example, below the window frame 4. A hollow tube mounting frame 45 is disposed on the side surface facing the frame 11. The hollow tube mounting frames 43, 44, 45 are, for example, H-shaped, and the panel 30 is fitted in one concave portion, and the hollow tube 14 is disposed in the other concave portion. The hollow tube mounting frames 43, 44, and 45 serve as guide rails for the hollow tube 14 to be always positioned on the side surface of the panel 30. That is, the hollow tube 14 is arranged on the side surface of the panel 30 in a U-shape.

  With this structure, the panels 15 to 19 and 28 to 30 are substantially integrated into a plate-like body, and when used as the additional window 1, the hollow tube 14 is securely attached to the panels 15 to 19 and 28 to 30. The panel 15-19, 28-30 receives a pressing force from the hollow tube attachment frames 41-45, 51-62 (see FIG. 5B). At this time, since the hollow tube mounting frames 41 to 45 and 51 to 62 are fitted to the panels 15 to 19 and 28 to 30, the pressing force is applied in a direction perpendicular to the side surfaces of the panels 15 to 19 and 28 to 30. It is transmitted. As a result, the panels 15 to 19 and 28 to 30 are reliably connected to the window frame 4 without being displaced in the vertical direction. At this time, the hollow tube mounting frames 41 to 45 and 51 to 62 are also connected to each other without any substantial gap due to the pressing force caused by the hollow tube 14 swelling, and the airtightness of the additional window 1 itself is improved. That is, the additional window 1 is used as if it were an integral window.

  In addition, even when only a panel is fitted by the hollow tube attachment frame, the case where the panel by which the connection sheet was bonded to the hollow tube attachment frame may be fitted.

  As shown in FIG. 4C, in the folded region of the panels 15 to 19 and 28 to 30, a part 46 of the hollow tube 14 is connected, and the other parts indicated by circles 47 and 48 are divided. It may be the case. In this case, it is only necessary to bend the portion 46 of the hollow tube 14, and it is easy to fold, so that it can be folded thinner when the additional window 1 is stored. On the other hand, as shown by circles 47 and 48, even in the divided region, by extending the hollow tube 14 to the periphery of a part 46 of the hollow tube 14, airtightness is impaired when used as the additional window 1. There is no.

  When the expansion window 1 is not in use, air is extracted from the hollow tube 14 and the hollow tube 14 is in a deflated state. There is no particular problem with ease.

  FIG. 5A shows a state in which the additional window 1 is installed in the window frame 4 and wound up and stored on the upper frame 9 side of the window frame 4 when not in use. A panel suspension plate 10 is fixed to the upper frame 9 of the window frame 4 using an adhesive material such as a double-sided adhesive tape. At this time, by making the width of the panel suspension plate 10 equal to the width of the window frame 4, there is no gap between the window frame 4 and the panel suspension plate 10, and the airtightness as the additional window 1 can be improved. .

  The panel suspension plate 10 includes, for example, a winding reel mechanism, and winds up a plurality of panels 15 to 19 and 28 to 30 via winding ropes 49 and 50. For example, when the thickness of the panels 15 to 19 and 28 to 30 is 1.0 (cm), the panel suspension plate 10 is thinned to about 8.0 (cm) on the upper frame 9 side of the window frame 4. Can be stored in a state.

  With this structure, consideration is given to dew proofing of the existing windows 7 and 8 (see FIG. 1A) and heat insulation of the opening region 3 (see FIG. 1A) of the structure 2 (see FIG. 1A). In such a situation, the additional window 1 is simply housed on the upper frame 9 side of the window frame 4. And since the storage space is not bulky, the opening and closing operation of the existing windows 7 and 8 is not hindered, and the scenery from the existing windows 7 and 8 is not impaired.

  The panel suspension plate 10 and the panel 15 are, for example, openings (not shown) formed in the panel suspension plate 10 with, for example, T-shaped suspension pins (not shown) fixed to the panel 15. It is connected by hooking. With this structure, after the panel suspension plate 10 is fixed to a desired location on the upper frame 9 of the window frame 4, the additional window 1 can be easily installed by hooking the bellows-like panel. Moreover, the installation location of the panel suspension board 10 is not limited to the upper frame 9 of the window frame 4, and is installed in the lower frame 11 and the left and right frames 12 and 13 of the window frame 4 according to the usage and the like. May be.

  In FIG. 5 (B), the extension window 1 is installed in the window frame 4, and the plurality of panels 15-19 and 28-30 are substantially integrated into a plate-like body and used as the extension window 1 having an airtight structure. The state is shown.

  First, the plurality of panels 15 to 19 and 28 to 30 are suspended from the panel suspension plate 10 by opening the winding reel mechanism of the panel suspension plate 10. At this time, as described above, since the plurality of panels 15 to 19 and 28 to 30 are connected by the connection sheets 20 to 23 and 31 to 35 (see FIG. 2B), they fall from the panel suspension plate 10. There is no. And since the panel 15-19, 28-30 width is narrower than the width | variety of the window frame 4, the lower frame 11, the left-right frames 12, 13 of the window frame 4, and the hollow tube attachment frames 41, 42, 43-45, 51- A gap is formed between the two and 62.

  Thereafter, air is injected into the hollow tube 14 to inflate the hollow tube 14. The hollow tube 14 swells in the hollow tube mounting frames 41 to 45 and 51 to 62, and then between the lower frame 11 and the left and right frames 12 and 13 of the window frame 4 and the hollow tube mounting frames 41 to 45 and 51 to 62. Fill the gap. At this time, the hollow tube 14 and the lower frame 11 and the left and right frames 12 and 13 of the window frame 4 are in close contact with each other, and by pressing from the hollow tube 14, the panels 15 to 19, 28 to 30 and the hollow tube mounting frames 41 to 45, 51-62 are also connected. With this structure, the air layer between the existing windows 7 and 8 and the additional window 1 uses the window frame 4 to be in an airtight state, so that the existing windows 7 and 8 are dew-proof and the heat insulating properties of the opening region 3 of the structure 2. Is realized. The suspension pin is inserted into the opening of the panel suspension plate 10 by the pressing force caused by the swelling of the hollow tube 14, and the panel suspension plate 10 and the panel 15 are brought into direct contact with each other. Airtightness between them is ensured.

  Furthermore, since the panel 15-19, 28-30 width is narrower than the width | variety of the window frame 4, a working space can be ensured and installation work is easy. And since the airtight state between the existing windows 7 and 8 and the extension window 1 can be adjusted by the amount of air injected into the hollow tube 14, it can be used as the extension window 1 easily.

  Although not shown, air injection holes (not shown) are provided in the hollow tube mounting frames 41 to 45 and 51 to 62 located on the indoor side, and air connected to the hollow tube 14 is provided in the air injection holes. A valve is arranged. Then, by using the air valve of the air injection hole, for example, by connecting a known air pump, it is possible to inject air into the hollow tube 14, so that the extension window 1 can be easily installed at home. It can be carried out.

  In the present embodiment, the structure in which the hollow tube mounting frames 41 to 45 and 51 to 62 are disposed on the three side surfaces of the additional window 1 and the panel suspension plate 10 is disposed on the remaining one side surface has been described. It is not limited to. For example, the hollow tube mounting frame is arranged on the four side surfaces of the extension window 1, and the air layer between the existing windows 7 and 8 and the extension window 1 is kept airtight by the hollow tube 14 on all sides of the extension window 1. It may be the case.

  Moreover, although this embodiment demonstrated the case where the expansion window 1 was comprised from several panels 15-19, 28-30, it is not limited to this case. For example, it may be composed of a single panel according to the shape of the window frame 4. Even in this case, the airtightness of the air layer between the existing windows 7 and 8 and the additional window 1 can be easily maintained by using the hollow tube and the hollow tube mounting frame.

  In the present embodiment, the case where the panel suspension plate 10 has a winding reel mechanism has been described. However, the present invention is not limited to this case. For example, the plurality of panels 15 to 19 and 28 to 30 may be manually folded and temporarily folded by hooking rubber or strings having locking members such as L-shaped hooks at both ends to the window frame 4. . In addition, for example, magnets may be arranged on the plurality of panels 15 to 19 and 28 to 30 and the hollow tube attachment frames 41 to 45 and 51 to 62 and temporarily folded into the window frame 4 by the magnets. In these cases, the hoisting reel mechanism (including the hoisting ropes 49 and 50) is omitted, so that there is no hoisting ropes 49 and 50 when used as the additional window 1, and the appearance from the additional window 1 is also improved. It becomes easy to see. In addition, various modifications can be made without departing from the scope of the present invention.

  Although the details will be described later, the structure of the extension window of the second embodiment is different in the structure of the panel suspension plate 10 (see FIG. 1 (A)) in the first embodiment. 1 is the same as the constituent member. Specifically, a plurality of panels constituting the additional window, a connection sheet, a resin sheet, a hollow tube, a hollow tube mounting frame, and the like. For the structure and effects in the structure, refer to the description of the first embodiment. Then, I omit the detailed explanation. In the description of the additional window in the second embodiment, the same reference numerals are given to the same components as those of the additional window in the first embodiment described above.

  As shown in FIG. 6A, the additional window 71 is installed in a window frame 74 of an opening area 73 formed in a structure 72 such as a building, a condominium, an apartment, or a house. It is located between the existing windows 77 and 78. The window frame 74 is made of, for example, wood, and is attached to a structure 72 on the indoor side of the opening region 73. On the other hand, for example, aluminum sash frames 75 and 76 are attached to the structure 72 on the outdoor side of the opening region 73. A pair of existing windows 77 and 78 are attached in the aluminum sash frames 75 and 76 so as to be freely opened and closed. The window frame 74 may be already attached to the structure 72, or may be newly attached to the existing window frame 74 or structure 72.

  As shown in FIGS. 6A and 6B, the extension window 71 is installed in close contact with the window frame 74 so that the air layer between the extension window 71 and the existing windows 77 and 78 is substantially airtight. Has been. Although details will be described later, for example, a movable panel suspension plate 80 of the additional window 71 is fixed to the upper frame 79 of the window frame 74 with double-sided adhesive tape or the like, and the lower frame 81, the left frame 82, and the right frame of the window frame 74 are fixed. 83 is in contact with the hollow tube 14 of the additional window 71 and the airtight state is maintained.

  As shown in FIGS. 7A and 7B, the side surface 84 of the movable panel suspension plate 80 is fixed to the upper frame 79 of the window frame 74 (see FIG. 6A) by an adhesive material such as a double-sided adhesive tape. The The movable panel suspension plate 80 is fixed to the window frame 74 with a double-sided adhesive tape or the like, thereby preventing the window frame 74 from being damaged by nails, screws, or the like. Particularly, when it is desired to install an additional window 71 (see FIG. 6A) for an existing window such as a rental apartment or an apartment, it is an effective installation method that prevents damage to the window frame 74.

  Movable grooves 86 and 87 are formed in the movable panel suspension plate 80 so that the side surface 85 facing the side surface 84 is open. The opening grooves 86 and 87 are, for example, T-shaped and open from the indoor side to the existing window side. The extension window 71 can move in the window frame 74 using the opening grooves 86 and 87, and the distance between the existing windows 77 and 78 (see FIG. 6A) and the extension window 71 is the purpose. It can be changed easily according to the situation. The opening shapes of the opening grooves 86 and 87 are not limited to the T-shape, and movable pins 94 and 95 (see FIG. 8A) for suspending a plurality of panels are movable grooves 86 and 87. Any shape that does not fall from the surface may be used.

  As shown in FIG. 7C, a supplementary plate 88 can be attached to the movable panel suspension plate 80 according to the size of the window frame 74. The size of the window frame 74 varies depending on the design of the structure, the size of the room, the design requirements, and the like. At this time, a size suitable for the width of the window frame 74 can be obtained by fixing the supplementary plate 88 to the movable panel suspension plate 80 with, for example, screws 89 and 90 and adding them. The movable panel suspension plate 80 and the supplementary plate 88 can be fixed in the window frame 74 by springs (not shown) instead of the screws 89 and 90.

  The caps 91, 92, 93 made of rubber, resin, etc. are fitted into the gaps between the opening grooves 86, 87 and the movable panel suspension plate 80 and the supplementary plate 88, thereby suppressing the flow of air. The airtight state of the air layer between the windows 77 and 78 and the additional window 71 can be maintained.

  As shown in FIG. 8A, the plurality of panels 15 to 19 and 28 to 30 are substantially formed as an integrated plate-like body, and a state of being used as the additional window 1 is shown. Movable pins 94 and 95 are attached to the panel 15 adjacent to the movable panel suspension plate 80. The movable pins 94 and 95 have, for example, a T shape together with the shapes of the opening grooves 86 and 87. The movable pins 94 and 95 can be freely rotated with respect to the panel 15 by being connected to the panel 15 by the rotary hinge structure. Further, the separation distance between the movable pins 94 and 95 and the separation distance between the opening grooves 86 and 87 are equal so that the movable pins 94 and 95 are disposed in the opening grooves 86 and 87.

  Although not shown, the movable panel suspension plate 80 may be provided with, for example, a winding reel mechanism, and the winding reel mechanism is provided between the movable panel suspension plate 80 and the panel 15. It may be the case. In the case where a winding reel mechanism is provided between the movable panel suspension plate 80 and the panel 15, the movable pins 94 and 95 only need to be mounted on the winding reel mechanism. When the winding reel mechanism is not used as the additional window 71, the plurality of panels 15 to 19 and 28 to 30 are wound up via the winding rope, and the plurality of panels 15 to 19, 28 to 30 can be temporarily stored.

  As shown in FIG. 8B, the extension window 71 is installed in the window frame 74, and the plurality of panels 15 to 19, 28 to 30 are substantially integrated into a plate-like body and have an airtight structure. The state being used as is shown.

  As described above, by installing the additional window 71 using the window frame 74, the air layer between the existing windows 77 and 78 and the additional window 71 becomes airtight. The heat insulating property of the opening region 73 (see FIG. 6A) of the structure 72 (see FIG. 6A) can be realized. At this time, with respect to the dew-proofing property, for example, it becomes a problem when the outside air temperature decreases in the winter, spring or autumn morning and evening, and the temperature difference between the inside and outside becomes large. Further, regarding heat insulation, for example, there is a problem of efficiency of heat insulation during heating in winter and cooling in summer. Furthermore, for example, the Japanese archipelago is long from north to south, and the outside air temperature and humidity are different depending on the region. In addition, the dew-proofing and heat-insulating efficiency vary depending on the weather conditions and the size of existing windows.

  In the present embodiment, by using the movable panel suspension plate 80 fixed to the window frame 74 and the movable pins 94 and 95 fixed to the panel 15, the existing windows 77 and 78 and the additional window 71 are appropriately connected. The separation distance can be changed. And after determining the separation distance between the existing windows 77 and 78 and the additional window 71, air is inject | poured in the hollow tube 14 and the hollow tube 14 is expanded. The hollow tube 14 swells in the hollow tube mounting frames 41 to 45 and 51 to 62, and then between the lower frame 81 and the left and right frames 82 and 83 of the window frame 74 and the hollow tube mounting frames 41 to 45 and 51 to 62. Fill the gap. At this time, the hollow tube 14 and the lower frame 81 and the left and right frames 82 and 83 of the window frame 74 are in close contact with each other, and the panels 15 to 19 and 28 to 30 and the hollow tube mounting frames 41 to 45 are pressed by the hollow tube 14. 51-62 are also connected. With this structure, the air layer between the existing windows 77 and 78 and the additional window 71 uses the window frame 74 to be in an airtight state, and the dew-proof property of the existing windows 77 and 78 and the heat insulation of the opening region 73 of the structure 72 Can be realized.

  As shown in the drawing, the movable pins 94 and 95 are inserted into the opening grooves 86 and 87 of the movable panel suspension plate 80 by the pressing force caused by the swelling of the hollow tube 14, and the movable panel suspension plate 80 and the panel 15 are connected to each other. By directly contacting, the airtightness between the movable panel suspension plate 80 and the panel 15 is ensured. As described above, the caps 91 and 92 are fitted into the opening grooves 86 and 87 of the movable panel suspension plate 80, so that the airtightness at the opening grooves 86 and 87 is secured.

  In other words, in the present embodiment, an optimum space between the existing windows 77 and 78 and the additional window 71 is easily determined according to various conditions such as the area where the additional window 1 is installed, the location conditions of the area, the weather, and the season.
