Description

[Detailed description of the invention] Built-in aluminum slat Venetian blind. In conventional double-glazed windows, the slats descend from the top to provide sunshading and interior glazing.

In this case, the slats are turned from outward to inward and completely closed, completely blocking the view.

Also, in the summer, the aluminum slats inside the hollow layer of double-glazed glass absorb radiant heat from the sun, which causes the temperature inside the hollow layer to rise, and that heat is transferred into the room through the inner glass.

Therefore, this type of double-glazed window cannot maximize the effectiveness of blinds in reducing the cooling load of the building.

Furthermore, with the structure in which the slats descend from above, it was not possible to shield the lower half of the window, which is particularly necessary.

The window of the present invention is a double-glazed window that solves these drawbacks, and has a fabric-like sunshade built into the hollow layer of the double-glazed window that rises from below and is not made of metal and absorbs less heat. It is a double-glazed window that can be raised and lowered freely by operating the lifting cord that is taken out from the indoor side.

The following describes an embodiment of a double glass window that rotates on the horizontal axis. In the window of the present invention, as shown in FIG. 1, 1 is a window frame and 2 is a double glass shoji. open,
and invert.

31 and 32 are strings for raising and lowering the awning 4, and this figure shows the awning 4 raised to the lower half of the shoji screen.

The lifting strings 31 and 32 are stopped by a stopper 6 attached to the shoji screen.

As shown in FIGS. 2 and 3, the sunshade 4 has an outer glass 10. In the hollow layer surrounded by the inner glass 11, an upper plate 14 is fixed to the upper end, and a lower plate 15 is fixed to the lower end, and is foldable by folds 12 and 13.

An axle box 17 is fixed to the hollow layer 16 side of the lower frame 9 of the shoji 2 along the lower frame 9, and the lower plate 15 is fixed to the upper part of the axle box 17.

On the other hand, a rotating shaft 23 is horizontally suspended in the axle box 17, and winding drums 19.20 are fixed to both ends of the rotating shaft 23. On the outside of each winding drum 19.20, there are threaded portions 21.22 in the same direction.
is provided.

The rotating shaft 23 is rotatably supported by left and right bearings 24,25.

26 is a coil spring which is wound in the middle of the winding drum 19, 20, has an inner diameter sufficiently larger than the diameter of the rotating shaft 23, and whose winding direction is opposite to the direction of the threads of the left and right threaded parts 21, 22. There is.

One end of the coil spring 26 is fixed to the winding drum 19, and the other end does not rotate even if it moves from side to side within the axle box 17.

In this embodiment, as shown in FIG. 3a, a longitudinal groove 42 is provided in the upper part of the inside of the axle box 17, and the end portion of the coil spring 26 is formed into an L shape, and a portion parallel to the rotation axis 23 is formed. The movable piece 43 to which 26a is fixed is slidably inserted into the groove 4.
It is included in 2.

Alternatively, the other end may be located at a corner of the axle box 17.

Two guide strings 27 and 28 are fixed to the left and right sides of the back surface of the upper plate 14, and pass through the through holes 29 and 30 between the folds 12 and 13 of the sunshade 4 and the through holes 39 and 40 of the lower plate 15. , are wound in the same direction on each drum 19,20.

This connects the two guide strings 27 and 28 to one of the drums 19 and 20.
It is fixed to the end, the rotating shaft 23 is rotated in the same direction as the threaded parts 21 and 22, and the threaded parts 21 and 22 are wound.

The number of windings is 27 when the guide string is returned to its original position.
The upper plate 14 to which the other end of the shoji 28 is fixed is wound so that it has a sufficient length up to the shoji upper frame 5.

At the left and right ends of the upper part of the upper plate 14, there are strings 31 and 32 for lifting and lowering.
is fixed, passes through the upper part of the upper part of the shoji upper part 5 and the husband rollers 33, 34, 35, 36 in the vertical part 8, and is taken out from the vertical part 8 of the shoji 2 to the indoor side, and there is a knob at the end. 38 is fixed.

Since the window of the present invention has the above-described structure, the sunshade 4 shown in FIG.
9.20, the threaded portion 21.22 at the end of the rotating shaft 23 is wound in any direction with a pinch.

When the awning 4 is in this state, if you pull the lifting strings 31 and 32 coming out of the vertical wall 8 of the shoji 2 toward the guide side, the other ends of each lifting string are fixed to the upper plate 14, so The upper plate 14 is pulled up in the direction of arrow 8.

Therefore, it is fixed to this.

The awning 4 is pulled up and raised one by one.

At this time, the guide strings 27.28 previously wound around each winding drum 19.20 are also passed through the respective through holes 39.40 while rotating the drum in the direction of arrow B, and the guide strings 27.28 are wound around the upper plate 14.
It is raised as the value increases.

The two guide strings 27.28 are connected to the winding drum 19.2.
Since the winding drum 19.20 is wound in the same direction and at the same pitch as the threaded portion 21.22, the winding drum 19.20 moves in the direction of arrow C while rotating.

Therefore, since the point where the guide string separates from the drum 19.20 is always directly below the through holes 39, 40, the guide string 27.2
8 is released from the through holes 39 and 40 without any difficulty.

In this way, for example, when the lower half of the sunshade 4 is blocked, by tying the lifting cords 31 and 32 to the stopper 6, the sunshade 4
will stop at that position.

In this way, the double-glazed window of the present invention becomes a double-glazed window in which the lower half of the window is shielded.

Next, in the same manner as above, the lifting strings 27 and 28 are further pulled until the upper plate 14 reaches the shoji upper frame 5 of the shoji 2, thereby making it possible to cover the entire window.

In such a double-glazed window, the sunshade 4 absorbs much less heat than metal, so the double-glazed window of the present invention has excellent shielding performance and can reduce the cooling load to the maximum. Moreover, since the window of the present invention is not obstructed at all, the livability of the building equipped with the window of the present invention is also extremely good.

Next, when the awning 4 is in the position shown in FIG.
．． 32 from the stopper 6, the upper plate 14 descends in the direction of arrow D, and the awning 4 extends above the lower plate 15 with the respective extensions 12
．． The tiles are alternately folded by 13.

At this time, the guide strings 27 and 28 are connected to the rotating shaft 2 when the sunshade 4 is raised.
3 rotates in the direction of arrow B, and the coil spring 26
is rotated in the winding direction, so when the sunshade 4 rises, the rotational force that always returns it to the state shown in Fig. 1 is applied to the rotating shaft 2.
3 acts in the direction of arrow E, which is the opposite direction to when it rotates, the winding drum 19,20 moves in the direction of arrow F while being wound in this direction.

Therefore, the guide strings 27, 28 do not slacken (as when the sunshade 4 is raised, they are wound around the winding drums 19, 20 directly under each of the through holes 39, 40, The awning 4 can be folded and returned smoothly to the position shown in FIG.

As described above, the window shoji 2 of the present invention can be moved at a certain angle lO
Even when the sunshade 40 is opened to an angle of 15° to 15°, the sunshade 40 guide strings 27 and 28 are always in a state where they do not loosen and the folds 12 of the sunshade 4
, 13, the sunshade can be raised and lowered smoothly, which was impossible with conventional Venetian blinds that lowered due to the weight of the lower plate. .

Therefore, it also has the feature that the shoji 2 can be opened to allow natural breeze to enter the room while shielding the lower half of the shoji 2 from the outside.

Further, in the horizontal axis rotating window as in this embodiment, the outer glass can be cleaned.

Even when the shoji 2 is reversed in this way, even if the axle box 17 is at the top, the winding drum 19.
If the force of the coil spring 26 is set so that the coil spring 20 does not rotate, the sunshade 4 will not fall.

Therefore, when raising the sunshade 4 in a normal case, the force required to raise the sunshade 4 while pulling the lift strings 31 and 32 and rotating the coil spring 26 in the winding direction is extremely small, and the operation can be performed smoothly.

FIG. 6 shows another embodiment of a double-glazed window with two built-in sunshades, in which a venetian blind 41 using slats descending from top to bottom, conventionally used on the outside of the sunshade 4, is shown. In such a double-glazed window, the two sunshades 4.41 can be raised and lowered freely to create a double-glazed window that meets the needs of various residents.

For example, when the room is darkened in order to have a good night's sleep, the room can be further darkened by lowering a normal Penetian blind to the outside of the sunshade 4.

Also, at a certain time, in order to block the upper half of the shoji from sunlight and hide the lower half of the shoji from the sun, so that the outside can be seen from inside, the Penetian blind 41 is lowered to the upper half of the shoji 2. This purpose can be easily achieved by raising the sunshade 4 to the lower half.
