Description

[Detailed explanation of the idea] The present invention relates to the improvement of double-tiered windows using metal profiles.

BACKGROUND OF THE INVENTION With the recent rise in the quality of living, attempts have been made to create windows using metal profiles such as aluminum sash to create step windows.

For the same reason, it has become necessary to install at least Japanese-style shoji, glass shoji, and shutters in that order from the indoor side, as well as blinds, screen doors, etc., as fittings to be built into the window frame. There is.

However, in order to erect such various types of fittings, the width of the upper and lower frame materials that make up the window frame, as well as the left and right vertical roofs, must necessarily be increased in width.To do this, the mechanical strength of the frame materials must be increased. It is necessary to significantly increase the width of the frame, and measures such as using hollow frames have been taken, but since these frames are attached to lintels, sills, and left and right pillars, only the left and right ends have to be No increase in wall thickness is required for the solid wood wall that is installed and supported.

If you create a two-tiered window by incorporating a matching blind into a large window frame that houses the outer and inner shoji,
The wall thickness of the blank material is very large, and therefore the price is high.

The present invention was developed in response to the demand for higher quality shoji and the problem of material saving. A stepped window with a blind accommodating part integrally provided between the two, and the blind accommodating part is separately attached to an outer shoji tiered window mumume and an inner shoji shoji, which are attached to both the left and right vertical frames at intervals in the indoor and outdoor directions. This is a two-tiered window made of a metal profile, characterized by a vertical gap between the two tiered windows.

The housing will be described with reference to the accompanying drawings showing one mode of its implementation.

In the figure, 1 is the upper frame, 2 is the lower frame, and 3 is the left and right vertical frames,
From the outside of the room, a screen door A, which forms one of the outer shoji screens, an outer shoji B, a blind D, and an inner shoji C are installed. .

In the present invention, in order to create a two-tiered window by incorporating blinds into such a large window frame, as shown in Fig. Uses a different Mume from Mume 5.

The width of the outer shoji step windowless 4 is equal to the width of the above-mentioned outer shoji accommodating section A, and the width of the inner shoji tier windowless 5 is similarly formed to be equal to y to the width of the inner shoji accommodating section opening. has been done.

The blind storage area C has this inner/outer shoji stage windowless 4°5.
This is the vertical space portion extending over the upper and lower frames 1 and 2 with an interval of .

In this way, the reason why the Mume 6 for the inner and outer shoji is not made as one piece as shown in the reference diagram is that with the one-piece Mume 6, the overall wall thickness is significantly increased to increase the strength. However, if divided blinds are used as in the present invention, the strength of the blinds 5 for internal shoji can be significantly reduced.
Even in terms of the total amount of inner and outer painting mumu, the required amount of mumu material is much smaller than that of a one-piece mumu, and incidentally, the space between the upper and lower frames that constitutes the above-mentioned space, the storage section. This is because it is possible to provide a blind D that passes through the window, and enjoy the benefits of lighting, heat insulation, etc.

The blind is hung in the usual manner on the upper frame 1 and closed by hooks I provided on the lower frame.

In addition, since the double-tiered window of the present invention has the inner and outer blinds completely separated, condensation is unlikely to occur on the indoor side of the inner shoji tier window 5.

In the present invention, the inner shoji tier windowless 5 can reduce the consideration on strength to a much greater extent than the outer shoji tier windowless 4.

For example, when external pressure such as wind pressure is applied to a window, the load is mainly borne by the outer shoji, but the inner shoji has very little of it.

Therefore, the reason is that even the strength of the outer shoji tiers and windows need to be satisfied.

Such a blind material for inner and outer windows according to the present invention can be easily manufactured by conventional extrusion molding means,
It is not comparable to the conventional large-scale integrated product shown in the reference drawing, which is difficult to manufacture.

In addition, as for the shape of these blind members, it is preferable to provide upright walls 4a, 5a at the upper end on the indoor side to prevent condensed water from flowing into the room.

In particular, the standing wall 4a of the outdoor wall contributes to preventing wind and rain from blowing in from the outside, and in the event that rainwater overflows the iron wall, the rainwater will fall into the center of the lower frame. It has the advantage of not contaminating indoor tatami mats, etc.

If the standing wall 6a is provided only at the upper end of the indoor side of the integrated wall 6 as shown in the reference drawing, such an effect will not be obtained, and rainwater will fall directly into the indoor side and cause contamination. be.

In addition, when attaching the blind D to the blind accommodating portion, a groove large enough to accommodate the blade of the closed blind is formed in the upper frame 1, and the groove is secured to the groove X as shown in the figure.

The opened blades are secured to hooks I provided on the lower frame in the usual manner.

Since the double-tiered window according to the present invention is entirely made of metal profiles, it is natural that the shutter housing section can be extruded in the upper, lower, and vertical sections as usual, but the shutter housing section can also be extruded in one piece. ,
As shown by reference numeral 8 in the figure, the outer shoji step window can be provided integrally with the outer shoji step window.

[Brief explanation of the drawing]

The accompanying drawings illustrate one embodiment of the double-stage window of the present invention, with FIG. 1 being a longitudinal cross-sectional view thereof, and FIG. 2 being a cross-sectional view thereof. In the figure, 1 is the upper frame, 2 is the lower frame, 3 is the vertical frame, 4 is the outer shoji tier windowless, and 5 is the inner shoji tier windowless.
