It is also conceivable to install sashes having the required heat insulation performance in terms of surface. However, the insulation sash window has a larger prospect of indoor / outdoor direction than a normal sash window, and when the insulation sash window and the general sash window are installed in one building, the window mounting structure, internal construction material and outer wall material With the
There was a problem that the appearance design and the like would be different.

A second object of the present invention is, when installing a general sash window or a heat insulating sash window, a sash window capable of unifying a mounting structure for a building, for example, a mounting structure for a building material or an outer wall material, and an external appearance design. To provide.

Here, the lower frames 73, 74 of the shoji screens 5A, 5B, the upper frame (not shown), the vertical frames, etc. have the expected dimensions in the indoor / outdoor direction corresponding to the frames 21-26 of the shoji screens 6A, 6B by the amount of holding the single plate glass 75. It is smaller than that. However, door carriage 3 of shoji 5A, 5B
The dimension between the two is the same as the dimension L2 between the rails 18 and 19, that is, the dimension between the door rollers 32 of the shoji screens 6A and 6B.

Further, (A) a general window frame 2 and (a1) a general sash screen 5 in combination, or (A) a general window frame 2
Since the sash window combining (1) and (a2) the general multi-layered shoji 6 has the same structure, the description thereof will be omitted.

In this embodiment as described above, appropriate window frames 1 and 2 and shoji 5 to 7 are selected in consideration of the area and environment in which the building where the sash window is installed, the installation location of the sash window in the building, and the like. Combine various sash windows 10, 40,
70 and 80 are formed. For example, when heat insulation performance is not so required in a warm region or when a sash window is installed on the south side of a building, the general window frame 2 and the general veneer shoji 5 may be combined to form the sash window. . When it is necessary to improve the insulation performance of the shoji by installing a sash window on the north side of the building, the general window frame 2 may be combined with the general multi-layered shoji 6 in order to further improve the insulation performance. The sash window 40 in which the heat insulating multi-layered screen 7 is combined with the general window frame 2 may be installed.

On the other hand, when the heat insulation performance of the window frame is improved, the heat insulation window frame 1 is used in place of the general window frame 2 and the sash window 1 in which the shoji 5, 5, and 7 are combined with the heat insulation window frame 1 is used.
It is sufficient to install 0, 70, 80. Among these, the sash window 80 in which the heat insulating window frame 1 and the heat insulating multilayered screen 7 are combined has the highest heat insulating performance.

The shoji screens 5 to 7 are originally the window frames 1 and 2.
Since it is removable, the heat insulating performance may be changed by appropriately replacing the shoji 5 to 7 in the sash window in which the window frame 1 or 2 is already installed.

According to this embodiment, the following effects can be obtained. That is, two types of window frames 1 and 2 and three types of shoji 5 to 7 are prepared, and each of the window frames 1 and 2 and shoji 5 to 7 is freely combined to produce various sash windows 10 and 4.
Since 0, 70, and 80 can be configured, it is possible to easily configure the sash window having the necessary heat insulation performance in each building. For this reason, in particular, like the sash windows 10 and 70 in which the heat insulating window frame 1 and the general shoji 5 and 6 are combined, only the window frame 1 is made an insulating type, and it is particularly effective in preventing dew condensation on the surface of the window frame 1. Like the type or the sash window 40 in which the general window frame 2 and the heat insulating multilayer shoji 7 are combined, only the shoji 7 is a heat insulating type to improve the heat insulating performance of the shoji 7 which holds the glass 29 having a large area. The type and the like can be appropriately selected.

Therefore, by combining the window frames 1 and 2 and the shoji 5 to 7, it is possible to construct the sash windows 10, 40, 70 and 80 having six stages of different heat insulating performance, respectively, as compared with the conventional one. It is possible to set a window having a heat insulation performance according to each building or the installation position of the window in the building. As a result, it is possible to use the heat insulating window frame 1 and the heat insulating multi-layered shoji 7 which are higher in cost than the general window frame 2 and the shoji 5 and 6, as much as necessary, and an inexpensive sash window suitable for heat insulating performance. Can be provided. Therefore, even in a region where a general sash window was used because the conventional heat insulating sash window did not match the cost, it is possible to use the sash window with improved heat insulating performance without increasing the cost so much. . Therefore, it is possible to improve the cooling and heating effect in the building, save energy, and suppress the occurrence of dew condensation.

Further, each of the shoji 5 to 7 has a window frame 1,
Since it can be attached to 2 as well, for example, even in a building where general veneer shoji 5 is attached, the sash window in which the shoji 5 is replaced with another shoji 6 or 7 to change the heat insulation performance later. Can be configured. In particular, since the shoji screens 5 to 7 are originally designed to be removable from the window frames 1 and 2, they can be easily replaced, and the heat insulation performance of the existing sash window can be easily and inexpensively changed.

Furthermore, the prospective dimensions of each shoji 5-7 are almost the same, and in particular, in the heat insulating multilayer shoji 7, by disposing the screw hole member 60 in the heat insulating materials 51C to 54C,
Since it is possible to have the same estimated size as the general multi-layered shoji 6, it is possible to use common accessories such as the screen door 33, and the cost can be reduced accordingly.

The estimated dimensions of the window frames 1 and 2 are the dimension L1.
The sash window is installed in the same structure as that of the sash window, and the estimated dimensions of each shoji 5-7 are almost the same. Which window frame 1, etc.
2 and shoji 5, 6, and 7 can be used in common. Therefore, in any combination of sash windows, design and construction can be simplified, workability can be improved, and cost can be reduced.

Furthermore, even if the types of sash windows to be installed on the south and north surfaces of one building are made different according to the required heat insulation performance, the installation structure and design can be made common, and It is possible to construct a building that has a good appearance and has a unified exterior and interior. Therefore, even in one building, it is possible to appropriately select and install the optimum sash window for each part such as the south surface and the north surface having different environments.

Further, in the heat insulating window frame 1, since the four heat insulating members 11C to 13C are continuously provided, the heat insulating members 11C to 13C are provided at positions closer to the indoor side than the rails 16 to 19, that is, along the indoor sides of the inner shoji 6B and 7B. 16 to 19 are outdoor members 11
Even if the rails 16 to 19 provided on the indoor members 11B and 12B are cooled by being exposed to the outside air.
It can be prevented from being transmitted to, and the heat insulation performance can be improved. Therefore, in the heat-insulating window frame 1, generation of dew condensation can be suppressed as compared with the general window frame 2, and a more comfortable living space can be formed.

Moreover, when the heat insulating member is arranged between the inner and outer rails, a part of the heat insulating member and the indoor member is exposed to the outside of the room, so that a resin cover material or the like must be provided. However, the number of parts increases and the cost increases, and since the cover material is closely attached to the rail, the thickness of the rail increases by the amount of the cover material added, and the shoji is formed according to the rail thickness. It must be done, and the structure of the shoji for heat insulating window frames and the shoji for general window frames is different,
Although it is not possible to switch to each other to form various combinations of sash windows, in the present embodiment, the heat insulating members 11C to 11C are used.
Since 13C is arranged at a position closer to the indoor side than the rails 16 to 19, a cover material is unnecessary, cost can be reduced correspondingly, and the thickness of the rail in the heat insulating window frame and the general window frame is reduced. It is the same, and therefore, various sash windows can be configured by appropriately combining each window frame and each shoji.

Further, each shoji 6 and 7 has each rail 16
Sealing material 59 that contacts the outdoor surface of -19 and the vertical frames 13 and 43
Since it is provided, it is possible to prevent the outside air from flowing into the indoor side from between the shoji screens 6 and 7 and the rails 16 to 19 and to further improve the heat insulation performance. In particular, adiabatic multi-layered shoji 7
In the above, by preventing the inflow of the outside air with the sealing material 59, the indoor members 51B to 56B of the shoji 7 can be prevented from being cooled by the outside air, and the heat insulation performance of the shoji 7 can be further improved.

The present invention is not limited to the above embodiment. For example, the heat insulating window frame 1 is not limited to that of the above embodiment, and as shown in FIG. 9, a non-ferrous metal outdoor member 91 and an indoor member 92 are separately molded and made of synthetic resin. It is also possible to use the heat insulating window frame 90 in which two plate-shaped heat insulating members 93 are arranged between the members 91 and 92 and caulked and connected (B2).

Further, as shown in FIG. 10, a (C1) heat insulating window frame 95 constituted by joining an outdoor member 96 made of a non-ferrous metal such as aluminum and a wooden indoor member 97 which is a heat insulating member is used. May be. Further, as shown in FIG. 11, an outdoor member 101 made of a non-ferrous metal such as aluminum and an indoor member 102 made of a synthetic resin such as polyvinyl chloride resin, which is a heat insulating member, are joined (C2) for heat insulation. The window frame 100 may be used.

In short, in the present invention, the heat insulating window frame has a heat insulating member (a member made of synthetic resin such as urethane or wood) in a part thereof so that the temperature of the outdoor member is not transmitted to the indoor side. It should be configured in. In addition, when the heat insulating window frame is used for the sliding window, the rail 1
It suffices that the dimension between the cores 6 to 19 is shared by L2. As a result, which window frame 1, 2, 90, 95, 100
Also in, the shoji 5 to 7 can be attached. Furthermore, if the estimated dimensions of the window frames 1, 2, 90, 95, 100 are made common to the dimension L1, the window frames 1, 2, 90, 95,
When 100 is attached to the body, the attachment structure can be made common and the workability can be improved.

The heat-insulating multilayer shoji 7 is not limited to the one in the above embodiment, but as shown in FIG. 12, the non-ferrous metal outdoor member 111 and the indoor member 112 are separately molded and made of synthetic resin. The two plate-shaped heat insulating materials 113 are attached to the respective members 111,
A heat insulating multilayer shoji 110 arranged between 112 and caulked and connected (b2) may be used.

As shown in FIG. 13, the outdoor member 116 made of non-ferrous metal and the wooden indoor member 11 which is a heat insulating member.
Alternatively, the heat insulating multilayer shoji 115 (c1) configured by joining 7 and 7 may be used. Further, as shown in FIG. 14, a non-ferrous metal outdoor member 121 and an indoor member 122 made of a synthetic resin such as polyvinyl chloride resin, which is a heat insulating member, are joined together (c2) heat insulating multilayer shoji 120 may be used.

In short, the heat insulating multi-layered shoji has a heat insulating member (a member made of synthetic resin such as urethane or wood) in a part thereof so that the temperature of the outdoor member is not transmitted to the indoor side. If you have. Further, when the heat insulating multi-layer shoji is used for the sliding window, the dimension between the door rollers of the indoor and outdoor shoji may be the same as the dimension L2 between the rail cores of the window frame. As a result, which shoji 5, 6, 7, 110, 11
5,120 can also be attached to the window frame. further,
If the shoji screens have almost the same expected dimensions, some screens will not interfere with the screen door 33, and other members such as the screen door 33 can be shared and the workability can be improved. Can be provided at low cost.

Further, although the sash window used as the sliding window has been described in the above embodiment, the present invention is
It can be applied to various sash windows having window frames and sliding doors such as a sliding window other than a sliding window, an opening window, a sliding window, a vertical sliding window, a raising / lowering window, an inside opening window, an outside opening window and the like.

For example, as shown in FIG. 15, (A1) a general window frame 132 made of non-ferrous metal as a window frame, and (B1) a mounting piece 131D to the body side on the indoor side in order to form a vertically extending window. 2 kinds of a heat insulating window frame 131 having a heat insulating member 131C are provided, and (a3) a general single plate shoji 135 in which single plate glass is incorporated into a non-ferrous metal window frame, and (a4) a non-ferrous metal window. General double-screen shoji with double-layer glass incorporated in the frame 1
36, (b3) Insulating multi-layered shoji 1 having a heat insulating member 137C
37 types, and these window frames 131, 132
One of the sliding doors 135, 136, 137 may be combined with one of the shoji screens to form the vertical sliding window.

Here, one of the general shoji 135, 136 is combined with the general window frame 132, and the heat insulation window frame 1 is formed.
With respect to 31, one of the shoji 135, 136, and 137 is appropriately combined. In addition,
The combination of the (A1) general window frame 132 and the (b3) heat-insulating multilayer shoji 137 may be set as necessary, and is not necessarily set. That is, when the general window frame 132 and the heat-insulating multilayer shoji 137 are combined, only the shoji is insulated, but in this case, in terms of heat insulation and dew-proofing compared to the case where only the window frame is heat-insulated. This is because the effect is small and not very practical.

Even in such a vertical sliding window, (A
1) General window frame 132 + (a3) General veneer shoji 135, (A
1) General window frame 132+ (a4) General multi-layered shoji 136, (B
1) Insulated window frame 131 + (a3) general veneer shoji 135, (B
1) Insulation window frame 131+ (a4) general multi-layered shoji 136, (B
1) It is possible to construct a vertical sliding window of a combination of five types of heat-insulating window frame 131+ (b3) heat-insulating multi-layered shoji 137 (6 types by setting a combination of general window frame 132 + heat-insulating multi-layered shoji 137). Since these 5 (6) types of vertical sliding windows have slightly different heat insulating performances, an optimum sash window can be set according to the building location area, environment, window installation position, and the like.

It should be noted that the same setting can be made for a pull-out window, an opening window, a side-opening window, a raising / lowering window, an inside opening window, an outside opening window, etc. other than the vertical opening window. Here, when constructing a heat insulating window frame in each of these windows, the heat insulating member may be semi-externally mounted and may be provided on the indoor side with respect to the mounting piece to the body. If the heat insulating member is provided on the indoor side of the frame mounting piece in this way, the heat conduction from the outdoor surface of the window frame can be reliably blocked by the heat insulating member, and the temperature decrease on the indoor surface of the window frame can be suppressed. , The dewproof performance can be improved. On the other hand, as in the above-mentioned embodiment, when the sliding doors such as sliding windows are provided inside and outside, the heat insulating member of the window frame is located along the indoor side of the sliding doors regardless of whether it is semi-externally attached or externally attached. Should be provided.

Further, various window frames and shoji screens are set according to the type of window so that they can be freely combined when constructing various windows, for example, in the case of sliding windows, window frames are used. The size of the rail core is the same as the size of the door roller of each shoji, and the other windows may have the same expected width, for example.

When constructing various sash windows including a sliding window and a vertical sliding window, whether or not a combination of a general window frame and a heat-insulating multilayered screen is possible or not can be appropriately selected in practice. Good.

Further, the parts other than the heat insulating member of each window frame and shoji may be made of non-ferrous metal such as aluminum or stainless steel, and the specific material may be appropriately selected according to the environment around the building to be installed. Good.

Further, the present invention, like the above embodiment,
(A) and (B) two types of window frames 1 and 2, and (a1) and (a
2), 3 is not limited to those with type shoji 5-7, For example, (A) Non-ferrous metal window frames, window frames with (B) a heat insulating member, (C) thermally insulating (b) Types of window frames (for example, C1 and C2 window frames 95 and 100) having indoor members of (1), (a) non-ferrous metal shoji, (b) shoji having a heat insulating member, (c) heat insulating property Shoji with indoor members (for example, c
The sash window may be configured by appropriately combining the three types of window frames (shoji 115, 120 of 1 and c2). In short, according to the present invention, at least two kinds of shoji screens and one or more kinds of window frames are prepared, and the heat insulation performance of the sash window can be made different by appropriately combining these shoji screens and window frames. It only has to be configured.

[0080]

According to the sash window of the present invention as described above,
The heat insulation performance can be set in multiple stages to achieve a cost commensurate with the performance, and the heat insulation performance of the existing sash window can be easily changed.

Further, if the estimated dimensions are the same in various window frames, when installing a general sash window or a heat insulating sash window, a mounting structure for a building, for example, a mounting structure for a work material or an outer wall material, or an external appearance design Etc. can be unified, construction workability can be improved, and a building with a unified design and excellent appearance can be obtained.
