Description

[Detailed explanation of the idea] This invention relates to an insulated double window frame.

An insulated double window frame was previously proposed in which insulation was improved by connecting an outer window frame and an inner window frame, which were framed separately, with a heat insulating material interposed between them. The fittings installed on these insulated double window frames were sliding glass shoji framed with metal frames, or sliding shoji and metal shutters.

Therefore, even if the window frame is thermally insulated from the inside and outside by a heat insulating material, the expected insulation effect cannot be obtained because heat leakage is likely to occur in the metal and glass parts of the shutter and sliding shoji.

This idea improves the mounting position of the outer window frame and the inner window frame that make up the double window frame with respect to the window opening forming frame, as well as the types and installation methods of fittings to be installed on each of these window frames. The purpose of the present invention is to provide a heat-insulating double window frame that provides high heat-insulating performance.

Next, an embodiment of this invention will be described based on the drawings.

Fl is the outside window frame of the semi-external type, and the upper frame H1,
The lower frame S1 and the left and right vertical frames J1□, J12 are connected in a rectangular shape, and the connecting edge 1 provided at the indoor end of each frame is connected to the inside of the window opening formed by the window opening forming frame 2. The lintel 2h, the window sill 2S, and the lintel 2h constituting the window opening forming frame are fitted with a flange-shaped mounting edge 3 that fits into the interior end of each window and extends outward along a common vertical plane. It is attached to the outdoor side of the pillar 2j by fixing it with nails 4.

The outer window frame F1 has a shoji fitting part a on the indoor side part,
1), and sliding shoji 5, 6 are slidably fitted and held in each shoji fitting portion.

The outer window frame also has a screen door sliding part C on the outdoor side of the shoji fitting part, if necessary, so that a screen door 7 can be installed.

In addition, the outer window frame is placed on the outdoor side of the screen door sliding part C.
It has an integral sliding part d for holding the shutter so that it can be opened and closed.

This shutter sliding part has a guide groove d1 for the lower opening formed in the upper frame H1 and a guide groove d2 for the upper opening formed in the lower frame SI.
and a door stop groove d3 formed by an auxiliary vertical frame J13, which will be described later, fixed to the outdoor side of one vertical frame J12.

The auxiliary vertical frame J13 has a mounting edge 9 provided at the indoor end, a base plate 10 extending from the mounting edge along the vertical frame J12 toward the outdoors beyond the vertical frame, and a vertical frame J1□. a bent edge 12 that is engaged with the locking edge 11 of the door stop groove d3;
and a surface grid fixing edge 1 which will be described later.
4, and the bent edge 12 is connected to the locking edge 11.
The mounting edge 9 is overlapped with the mounting edge 3 of the vertical frame J1□ and fixed with a common nail 4, so that it is integrally attached to the vertical frame J1□.

The auxiliary vertical frame J13 is also fixed to the upper frame and the lower frame by screws 15 screwed into the screw holes of the upper frame H1 and the screw holes of the lower frame S1.

Vertical frame J1. Since J1□ is formed symmetrically, the auxiliary vertical frame J13 can be attached to the vertical frame J1□ or J1□ depending on whether the door pocket described later is provided on either the left or right side of the window opening.

The upper frame H1 extends in the outdoor direction from the guide groove d1 forming the shutter sliding part to a vertical plane common to the surface grid fixing edge 14, and a downwardly opening groove e1 is formed at the outdoor end thereof. has been done.

Further, the lower frame S1 extends in the outdoor direction from the guide groove d2 forming the shutter sliding part d to a vertical plane common to the surface grid fixing edge 14, and has a concave groove with an upward opening at the outdoor end thereof. e2 is formed.

The upper surface of the lower frame S1 is sloped downward from the indoor end to the groove at the outdoor end, so that rain, cleaning water, or condensed water can easily flow outdoors.

Drain holes are provided in the groove e2 as appropriate.

The upper frame H1 and the lower frame S2 have hollow parts 16 and 17 between their respective mounting edges and the shutter sliding part d, so that the strength against the load of the shoji when the outer window frame is partially attached is increased. Reinforced.

A longitudinal half of a connecting block 18.19 having the same cross-sectional shape as the hollow portion is inserted into each of the hollow portions 16.17.

C is a door pocket, and with respect to the vertical frame J11, there is a pillar 2 on the opposite side of the vertical frame J1□ to which the auxiliary vertical frame J13 is attached.
A door bottom board 23 fixed to d with nails 21, a end board 24 provided at an appropriate distance on the outdoor side of the vertical frame J1+, and a door bottom board 23
and a mirror plate 25 fixed between the outdoor end portions of the end plates 24, a plate plate 26 extending in an extension of the lower frame and extending in the outdoor direction to the lower side of the mirror plate, and the upper frame. It is composed of a top plate (not shown) that continues on the extension of H1 and extends downwardly in the outdoor direction to the upper side of the mirror plate 25, and a mounting edge provided at the indoor end of the door end plate 23. 23' to the pillar 2d with nails 21, and the connecting block 18.1
The remaining half of the block 9 is pushed into a hollow part provided in the top plate and plate plate 26 and having the same cross-sectional shape as the block.

In this way, the shutter sliding part d communicates with the shutter storage part f formed in the door pocket C between the end plate 24 and the vertical frame J1□, and the shutter 8 is connected to the shutter sliding part d or the shutter storage part f. can be moved to open and close window openings.

The end plate 24 is the surface lattice fixing edge 1 of the auxiliary vertical frame J13.
4, and these end plates 24 and the surface lattice fixing edge 1
4 and the grooves e□ and e2 on the upper and lower frames constitute a surface grid mounting portion e.

The area grid according to the illustrated embodiment includes a plurality of vertical grids 27...
..., groove e1. e2 are arranged at appropriate intervals in the longitudinal direction, and the upper and lower ends of each vertical lattice are formed into grooves e1. e2 from the inside of the indoor side hanging wall 28 that forms the upper groove e1, and the indoor side hanging wall 2 that forms the lower groove e2.
9 are fastened from the inside with screws 30, respectively.

Since the screws 30 are fixed from the indoor side, there is a crime prevention effect.

Incidentally, if vertical lattice parts 24', 14' having the same appearance as the vertical lattice 27 are integrally provided on the auxiliary vertical frame J 13 and the end plate 24, the external appearance on both sides of the surface lattice can be improved.

However, the structure of the surface lattice installation is not limited to that shown in the figure, and the surface lattice assembled in advance can be attached to the auxiliary vertical frame J13 and the end plate, and if necessary, the upper and lower frames extend toward the outside. Just install it.

Figures 3 and 4 show an embodiment in which the handrail is integrally attached.

When attaching a handrail, it is preferable that the upper frame H1 not extend toward the outside from the shutter sliding part d as shown in the figure, so that the amount of daylight from the window becomes greater than in the first embodiment.

Further, the lower frame S1 integrally has a handrail fitting part e2' on the lower side of the guide groove d2 forming the shutter sliding part d.

Then, the cap 31 is fitted between the opposing surfaces of the auxiliary vertical frame J 13 and the end plate 24, and the auxiliary vertical frame J 13 and the end plate 24 are fitted.
Screws are screwed into the screw holes 32 of the cap 31 from the outside to fix the cap, and the lower end of each balustrade 34 whose upper end is connected to the cap 31 with the screw 33 is fitted into the balustrade. The handrail is attached by fitting into the joint e2' and circumferentially surrounding it with a screw 35.

In the illustrated embodiment, the auxiliary vertical frame J is separate from the vertical frame J12.
13, and by integrally connecting this to the vertical frame, a face lattice handrail can be installed between the end plate 24 and the auxiliary vertical frame J.

With such a configuration, there is an advantage that the mounting position of the auxiliary vertical frame can be easily changed depending on the position where the door pocket is installed.

However, instead of using a separate auxiliary vertical frame, the vertical frame J12 itself is extended toward the outdoors beyond the shutter sliding part to form a fixed edge, and a surface lattice etc. is installed between the fixed edge and the end plate. It's okay.

F2 is an inner window frame, and similarly, an upper frame H2 and a lower frame S2,
A shoji fitting part in which the left and right vertical frames J2□, J2□ are framed in a rectangular shape by a well-known technique using screw holes and screws, and the inner sliding shoji 5', 6' are slidably fitted. a

The connecting edge 1 of the outer window frame and the connecting edge 36 of the inner window frame are:
Each of them is continuous in a rectangular shape, and the rectangle formed by the former connecting edge 1 is larger than the rectangle formed by the latter connecting edge 36, so that the latter connecting edge can be fitted inside the former connecting edge in a nesting manner. can.

A dovetail groove 36 is formed on the outer periphery of the connecting edge 36 of the inner window frame, and a heat insulating material 37 protruding outward from the connecting edge is fitted into the groove.

The heat insulating material 37 is also continuous in a rectangular shape along the periphery of the inner window frame.

In this way, the inner window frame F2 is fitted to the inside of the window opening from the indoor side, and its connecting edge 36 is fitted to the inner side of the connecting edge 1 of the outer window frame while compressing the heat insulating material, thereby forming the outer window frame. The inner window frame is connected to the inner window frame in a thermally insulated state with a heat insulating material 37 interposed therebetween.

Both window frames are fixed to the window opening forming frame by screwing screws 38 into the window opening forming frame from inside the window opening at the overlapping connecting edges 1 and 36.

If necessary, add upper frame H2 and vertical frame J1□ of the inner window frame.
The inner window frame may be more firmly fixed by screwing in the screws 39 from above.

The fitting sliding part g of the inner window frame F2 has a guide groove g1 for a lower opening provided at the indoor end of the upper frame H2 on the indoor side of the window opening forming frame, and a guide groove g1 for the lower opening provided in the indoor side end of the upper frame H2 It consists of a rail g2 provided at the inner end portion of the window opening forming frame closer to the indoor side than the indoor side surface.

In the illustrated example, the rail g2 is composed of a protrusion 40 on which the door roller is placed and a protrusion support part 41.The protrusion support part is formed into a rectangular tube shape to increase its strength, but the protrusion support part is The rail g2 may have a simple flat plate shape, or the rail g2 may have a groove shape that opens upward.

The fitting sliding part extends the guide groove g1 and the rail g2 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 g is opened indoors. ' are provided in series, and when the heat insulating fittings 42 are slid and housed in this door pocket g', the window opening can be completely opened.

An auxiliary vertical frame J13 having a doorstop groove 43 and a mounting edge 44 is provided at the end of the door pocket g', and a nail 45 is inserted into the pillar 2d from the mounting edge.
It is installed by driving it into the

The guide groove g' and rail g2 of the fitting sliding part g are provided so as to be located on the indoor side of the window opening forming frame, so that the fitting sliding part g can be moved to the left and right sides of the window opening. The window opening can be easily opened completely by extending it outward and using it as a door pocket and 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 fittings 42 may be any known sliding door made of a material with a low heat transmission coefficient, and one, two or more sliding doors may be installed depending on the width of the window opening.

Translucent materials may be used, but if you use light-blocking materials,
It can be used as a shutter to block out external light at night, and can also be used as a blindfold.

Window frame F1. Installation of F2, auxiliary vertical frame J
After the installation of work 3 is completed, the wall base 46 is fixed, and the interior and exterior finishing walls 47, 48 and caulking material 49 are applied.

In the illustrated embodiment, an example has been described in which only one fitting sliding portion g is formed, but two or more fitting sliding portions may be provided and the fittings may be installed in a sliding pattern.

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.

A shutter 8, outer sliding shoji 5, 6, inner sliding shoji 5', 6', and insulation fittings 42 are installed on the inner and outer window frames installed as described above, and when all of these are closed,
The windows are arranged in four layers, and a relatively airtight insulating air layer is formed between them, resulting in an extremely high heat insulating effect.

In particular, if airtight materials 50, 51 that are in close contact with the fittings 42 are attached to the guide groove g1 and rail g2 of the sliding part of the fittings, cold air flowing into the room from the window can be more effectively prevented.

As shown in FIG. 5, the inner window frame F2 and the fitting sliding part g may be formed separately and connected integrally.

By having separate configurations, the outer window frame F1 and the inner edge frame F2
are connected in advance with a heat insulating material 37 interposed between them, and this is fitted into the window opening from the outdoor side and installed.
Fitting sliding part g can be attached.

Alternatively, connecting edges 52 and 53 protruding 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 g1 and the rail g that constitute the sliding part of the fittings are provided.
Connecting edges 54 and 55 protruding toward the outside of the room are provided on each of the connecting edges 54 and 55, and a heat insulating material 56 is interposed between the connecting edge of the upper frame, the connecting edge of the guide groove, the connecting edge of the lower frame, and the connecting edge of the rail. Alternatively, they may be stacked one on top of the other without intervening a heat insulating material, and the respective connecting edges may be connected and fixed with screws 57.

If the sliding parts of the fittings are formed separately in this way, when installing the heat-insulating fittings 42 so that they can be fully opened, the molding materials forming the inner window frame and the molding materials forming the guide grooves and rails can be separated as required. Since it can be cut to length, it is good for deep cuts.

As described above, according to this invention, firstly, the outer window frame is extended outward from the window opening forming frame and fixed to the outdoor side of the window opening forming frame, and the inner window frame is fixed to the outside side of the window opening forming frame. Since it is fitted and fixed inside the window opening forming frame, the window
It can easily accommodate four types of fittings: shutters, external sliding shoji, internal sliding shoji, and insulating fittings.

Second, because the insulating fittings were installed on the indoor side of the inner window frame, which is thermally insulated from the outer window frame by insulation material, it is better to install the insulating fittings on the outer window frame, which is not completely thermally insulated from the outside temperature. Also, a significantly higher insulation effect can be obtained.

Moreover, from the outdoor side to the indoor direction, there are shutters, external sliding shoji,
The inner sliding shoji and the insulating fittings are connected in four layers in this order, and due to the insulating air layer between each fitting, the heat transmission coefficient of each fitting becomes lower as it moves towards the indoor side, Since heat is most effectively blocked, the heat transmission coefficient of the entire window is also extremely low.
