Description

[Detailed description of the invention] This invention relates to a triple-insulated window whose insulation effect is particularly increased.

In order to improve the insulation performance of windows, so-called double sashes are used, in which sliding sliding shoji are installed double inside and outside.

The window frames that make up this type of double sash include a single type that is continuous from the indoor end to the outdoor end, and an inner window frame that has an inner sliding shoji and an outer sliding sash. A split type is known in which the outer window frame is formed separately and the inner window frame is connected with a heat insulating material interposed between them.The latter has a significantly lower heat transfer coefficient in the window frame. Therefore, it has better insulation properties than the former.

However, since window frames and shoji frames are both made of materials with good thermal conductivity, even with double sash, the insulation properties are not perfect.Especially in cold regions where the outside temperature drops significantly, or at night, the indoor temperature There was a problem that the performance was reduced.

In addition, double sashes have also been proposed that allow the shutters to be opened and closed, but they do not require the windows to be opened temporarily in order to close the shutters, especially when the outside temperature is low in the evening. It has the disadvantage that it escapes to the outside.

This idea involves integrally providing the inner window frame of the split window frame with a fitting part that holds the heat-insulating fittings on the indoor side, and triple-blocking the window opening with the inner and outer sliding shoji and the heat-insulating fittings. The purpose of the present invention is to provide a triple-insulated window that significantly improves the insulation effect when closed.

Next, one embodiment of this invention will be explained based on the drawings.
1 is a semi-external type outer window frame, and as in the past, the upper frame H1, lower frame S1, and left and right vertical frames J1 are framed into a rectangular shape using well-known technology using screw holes and screws. It is equipped with shoji fitting parts a, l) in which the outer sliding shoji 1 and 2 are slidably fitted, and a screen door fitting part C in which the screen door 3 is slidably fitted, It has a flange-shaped mounting edge 4 that extends outward from the base frame along a common vertical plane on the indoor side of the inner shoji fitting part a, and extends from the inner peripheral part to the indoor side end of the outer window frame. A connecting edge 5 is provided that projects toward the interior.

Further, reinforcing walls 6 are formed on the base frame as necessary.

7 is the incisal edge of the external appliance. F2 is an inner window frame, and similarly, the upper frame H2, the lower frame S2, and the left and right vertical frames J2 are framed in a rectangular shape using screw holes and screws, and the inner sliding shoji 8, A connecting edge 10 that has shoji fitting parts d and e that slidably fit into the connecting edge 9 of the inner window frame, and that protrudes toward the outdoor direction corresponding to each connecting edge 5 of the outer window frame at the outdoor end of the inner window frame. In addition, a fitting sliding part f for slidably fitting and holding the heat insulating fitting 11 is integrally provided at the indoor end.

The connecting edge 5 of the outer window frame and the connecting edge 10 of the inner window frame are:
Each is continuous in a rectangular shape, and the rectangle formed by the former connecting edge 5 is larger than the rectangle formed by the latter connecting edge 10, so that the latter connecting edge can be fitted inside the former connecting edge in a nesting manner. can.

A dovetail groove 10' is formed on the outer periphery of the connecting edge 10 of the inner window frame, and a heat insulating material 12 projecting outward from the connecting edge is fitted into the groove.

The heat insulating material 12 is also continuous in a rectangular shape along the periphery of the inner window frame.

With the above-mentioned configuration, first, the connecting edge 5 of the outer window frame F1 is brought into contact with the inner circumferential surface of the window opening formed by the window frame 13 consisting of the lintel, window sill, and pillar from the outdoor side, and the attachment is performed. The edge 4 is brought into contact with the outdoor side of the wooden window frame, nails 14 are driven into the mounting edge 4 to fix the outer window frame to the building, and then the inner window frame F2 is fitted from the indoor side to the inside of the window opening. Then, the connecting edge 10 is fitted inside the connecting edge 5 of the outer window frame while compressing the heat insulating material, and the outer window frame and the inner window frame are heated by the heat insulating material 12 interposed therebetween. Connect in an insulated state.

Both window frames are fixed to the window frame by screwing screws 15 into the window frame from inside the window opening at the overlapping connecting edges 5 and 10.

If necessary, screws 16' may be further screwed into the upper frame H2 and vertical frame J2 of the inner window frame to further securely fix the inner window frame.

The fitting sliding part f of the inner window frame F2 has a downward opening guide groove f1 provided at the indoor end of the upper frame H2 on the indoor side of the wooden window frame than the indoor side, and a lower opening guide groove f1 provided on the indoor side of the lower frame S2. It consists of a rail f2 provided at the end of the wooden window frame closer to the indoor side than the indoor side.

In the illustrated example, the rail f2 is composed of a protruding line 17 and a protruding line support part 18 on which the door roller is placed, and the protruding line support part is formed into a square tube shape to increase its strength. may be a simple flat plate, or rail f2
may be in the form of a groove that opens upward.

The fitting sliding part extends the guide groove f1 and the rail f2 along the indoor wall surface to the outside of either the left or right side of the window opening, or both, so that the door pocket f is opened indoors. ′ is provided in series, and the fittings are connected to this door pocket f.
1, and the window opening can be completely opened.

An auxiliary vertical frame J3 having a doorstop groove 19 and a mounting edge 20 is attached to the end of the door pocket f'1 by driving a nail 21 into a post 22 from the mounting edge.

The guide groove f1 and rail f2 of the fitting sliding part f are provided so as to be located on the indoor side of the wooden window frame, so the fitting sliding part f is placed on the left and right outside of the window opening. By extending it integrally and making it a door pocket part, the window opening can be easily opened completely by sliding the fittings.

Depending on how the sliding part of the fitting is extended, it is possible to pull the fitting to either one side or to the other.

The heat-insulating fitting f may be any known sliding door made of a material with a low heat transmission coefficient, and one or more sliding doors may be transparent depending on the width of the window opening.

Translucent materials may be used, but if you use light-blocking materials (↓
, and can be turned into rain shutters to block out external light at night (
I'm blindfolded too.

Window frame F1. Installation of F2, auxiliary vertical frame J
After the installation in step 3 is completed, the wall base 23 is fixed, and the interior and exterior finishing walls 24, 25 and caulking material are applied.

In the illustrated embodiment, an example in which only one fitting sliding portion is formed has been described, but two or more fitting sliding portions may be provided, and the fittings may be transparent in a user-like manner.

In this case, the fitting sliding part may be extended to the outside of the window opening so that it can be fully opened, but it may not be extended and may be drawn to one side within the window opening.

In any case, when the shoji 1, 2, 8, 9 are installed in each shoji fitting part of the installed window frame, and the insulation fittings 11 are installed in the sliding part of the fittings, and closed, the window is closed. Tachi Shoji 1
. Highly insulating air layers 27 and 28 are formed.

Therefore, compared to conventional double-glazed windows, a much higher thermal insulation effect can be obtained.

It goes without saying that since the windows are triple-shielded, the soundproofing effect is significantly better than that of conventional windows.

Furthermore, if the fittings 11 are light-blocking, opening them allows for daylight, a view of the outside, and ventilation in the same way as a conventional double sash.

As shown in FIG. 3, the inner window frame F2 and the fitting sliding portion f may be formed separately and connected integrally.

By having separate configurations, the outer window frame F1 and the inner window frame F
2 are connected in advance with a heat insulating material 12 interposed therebetween, and after this is fitted and attached to the window opening from the outdoor side, the fitting sliding part f can be attached.

Alternatively, connecting edges 27 and 28 that protrude toward the interior of the room are provided at the indoor end of the upper frame H2 and lower frame S2 of the inner window frame F2, and the guide groove f1 and the rail f that constitute the sliding part of the fittings are provided.
Connecting edges 29 and 30 protruding toward the outside of the room are provided on each of the connecting edges 29 and 30, and a heat insulating material 31 is interposed between the connecting edge of the upper frame and the connecting edge of the guide groove, and the connecting edge of the lower frame and the connecting edge of the rail. Alternatively, they may be overlapped and each connecting edge may be connected and fixed with screws 32 without intervening a heat insulating material.

In this way, when the sliding parts of the fittings are formed separately, when installing the heat-insulating fittings 11 so that they can be fully opened, it is necessary to distinguish between the molding material forming the inner window frame and the molding material forming the guide groove f1 and the rail f2. Since it can be cut to a predetermined length, yields are high.

As described above, according to this invention, since a split window frame is used, heat conduction through the window frame is blocked, and in addition, the sliding part of the fittings is placed closer to the indoor side than the sliding shoji of the inner window frame. Since the heat insulating fittings are slidably held in the sliding parts of the fittings,
When all the sliding shoji and heat-insulating fittings are closed, the window is triple-blocked, resulting in much better heat and sound insulation than before.

Furthermore, when using heat-insulating fittings with light-shielding properties, it prevents light leakage and intrusion at night, and also serves as a blindfold, making it possible to live a safe and peaceful life.

Furthermore, since the fitting sliding part is naturally installed on the indoor side, by extending it outward from the window opening along the indoor wall surface, all the insulation fittings can be slid and stored outside the window opening. It is easy to open the entire opening.

Since the heat-insulating fittings face the interior of the room, they can be used for interior decoration by drawing various pictures, pasting photographs, wallpaper, etc. on them.
