Description

[Detailed description of the invention] The present invention relates to a blind that improves the heating and cooling effect in summer and winter, and also aims at a design effect by changing the color on the indoor side.

The blind referred to in this invention is a type of sunshade in which a large number of slats made of thin metal plates are arranged horizontally in parallel and connected to a cord for tilting the slats, and the inclination angle of the slats can be adjusted arbitrarily. This refers to something that blocks light.

Blinds that absorb or reflect solar heat have been known for a long time, and a typical air-conditioning sash described in Japanese Patent Publication No. 198, 1973, has the upper surface of each slat formed as a heat-reflecting surface and the lower surface formed as a heat-absorbing surface. , each slat can be rotated 180 degrees around its respective horizontal axis.

Therefore, if one surface is placed at a desired inclination angle facing outside, the other surface will face indoors, and since several surfaces are formed of a heat reflecting surface and a heat absorbing surface, It is possible to produce design changes.

However, since this air conditioning satsume was originally invented to absorb or reflect solar heat and effectively utilize the air conditioning function in buildings, the shape and color of the heat reflecting surface and heat absorbing surface are unique. However, the design value of the room cannot be improved.

In addition to this air-conditioning window, there is a blind that absorbs or reflects solar heat as described in Japanese Utility Model Publication No. 53-30840.

As shown in FIG. 10, each slat A has a width 2d that is approximately twice the distance d between adjacent slats.
By color-coding, solar heat is absorbed and reflected.In the winter, when solar heat is absorbed, the inside of the room is a warm light pink, and in the summer, when solar heat is reflected, the inside is a cool light blue. It was designed so that it was facing the right direction.

The structure is shown in FIG. 10. B is a reflective color with aluminum foil etc. attached, C is a solar heat absorbing color such as black, D is a pale blue cladding, and E is a pale pink cladding.

In the summer, as shown in Figure 11, this usage method is to paint all the outdoor surfaces of the blinds with a reflective color B, so that the indoor surface faces a pale blue color, while in the winter, as shown in Figure 12. As shown, the absorption color 0 is on the outdoor surface and the light pink color E is on the indoor surface.

Therefore, in this case, the indoor side becomes pale pink when heat is absorbed, and the indoor side becomes pale blue when heat is reflected.Although the color of the indoor side has been improved by the prior art described above, there are still the following drawbacks.

In other words, when the flats of the blind are used completely closed, favorable colors appear on the interior side, but when the blinds are used with the slats open, i.e. when daylight is required, the color tones on the interior side are more favorable. Discordant absorption color (
(black) or reflective color (white) appears.

Generally, it is during the day that solar heat needs to be absorbed and reflected.
It is necessary from the viewpoint of energy conservation to bring in the brightness of the outdoors during the day and save energy for indoor lighting.Therefore, it is necessary to improve the problem of inharmonious color tone when the slats are open. was desired.

The present invention improves the drawbacks of both conventional techniques, and includes a blind composed of a large number of slat plates that are rotatable around their respective horizontal longitudinal axes. The main slat plate has a light color on the bottom surface that gives a cool feeling, such as light blue paint, and a solar heat reflective surface on the top surface, and a warm color color that gives a warm feeling, such as orange paint on the bottom surface. The secondary slat plates are arranged horizontally and parallelly at regular intervals, and one of the slat plates of the above-mentioned type and the comic slat plate is placed on the upper or lower surface of the other adjacent slat plate. By making it possible to move up and down so that they are in contact with each other, it is possible to select either the solar heat absorbing surface or the solar heat reflecting surface as appropriate, which improves the cooling and heating effect in summer or winter, and also improves the indoor side during each use. The objective is to provide a blind that can have a great design effect by changing the color on the indoor side by making it possible to make the color tone suitable for each period of use.

Hereinafter, the present invention will be described with reference to embodiments shown in the accompanying drawings.

In Fig. 1, 1 is a top box with a hollow space, 2 is a bottom rail with rigidity and appropriate weight, and a number of rectangular plate-shaped slats with a medium-height curved cross section are spaced apart from each other at regular intervals between the top box and the bottom rail. Arrange the board group.

The slat plate group is constructed by alternately arranging main slat plates 3 and sub-slat plates 4.

Both slat plates are provided with elongated holes 5 through which a slat plate hoisting cord, which will be described later, is inserted, and both slat plates 3.4 are formed of thin plates such as aluminum alloy plates having exactly the same shape.

A slat board tilting board 31 is provided in the top box 1, and between the board 31 and the bottom rail 2, a plurality of slat board winding cords 7 and a plurality of pairs of slat board tilting cords 8, 8 are installed.
Set up.

The slat board-wrapped soil cord 7 is inserted into the long hole 5 described above, and its upper end is the long hole 3 provided in the slat board tilting board 31.
Penetrate 2.

The pair of slat plate tilting cords 8.8 are attached to the main slat plate 3, and are normally engaged with both ends of the main slat plate 3 in the width direction around the elongated hole 5, and their upper ends are attached to the slat tilting base plate 31. Fixed.

The tilting cord 8.8 used in the present invention has the same structure as the stepped tape used in ordinary blinds, and is formed into a ladder shape by connecting both cords with a horizontal hanging string.

FIGS. 2 and 3 show the locked state of the main slat plate 3 and the slat plate tilting cord 8.

As shown in FIG. 2, the locking metal fitting 11 has a base 13 having a notch 12 on the side and a curved base 13 having a middle height, and a partially notched portion 14.14 on the upper surface bent inward from both edges of the base. A notch 16.16 is formed near both ends of the base 13 corresponding to the bottom of the notch 14.14 and perpendicular to the notch 14.14.

FIG. 3 shows a state in which the main slat plate 3 is fitted onto the above-mentioned locking metal fitting 11.

H-shaped connection with horizontal hanging line 17 and slat plate tilting cord 8.8 (shown with dotted lines for clarity)
is first introduced into the notch 16.16 and then into the notch 14.14 of the locking metal fitting 11 to attach the locking metal fitting, and the main slat plate 3 is inserted into the U-shape of the locking metal fitting from above in FIG. Groove 15.
15 using its elasticity.

Returning to FIG. 1, between the top box 1 and the lowest sub-slat plate 4, there are multiple pairs of sub-slat board lifting cords 9.9.
is installed.

The sub-slat board lifting cord pair 9.9 is connected to the sub-slat board 4 in the same manner as the slat board tilting cord 8, and its upper end extends through the insertion hole 33.33 provided in the slat board tilting base plate 31. Then, they pass through the insertion hole 34 together.

Therefore, the cord 9 for lifting and lowering the sub-slat plate also serves as a cord for tilting the sub-slat plate 4.

The locking metal fittings 11 are used in the above explanation to prevent the slats from swerving in an incorrect posture within the tilting cord pair when the slat plates are tilted, and the slat plates must have sufficient weight. At times, no locking hardware is required.

Further, the shape of the locking metal fitting 11 is not limited to this embodiment.

Figure 4 is a diagram showing the relationship between each cord 7, 8, 9 and the main and sub-slat plates 3 and 4. For ease of explanation, the relative positions of the hoisting cord 7 and tilting cord 8 are shown in the blind. The difference from FIG. 1 is that they are spaced apart from each other in the longitudinal direction.

In the blind constructed as described above, the main slat plate 3 has a solar heat absorbing surface 3a that is painted black or selectively treated with heat absorption on the upper surface, and a bright color 3b that is painted light blue or the like on the lower surface to give a refreshing feeling. On the other hand, the sub-slat plate 4 has a solar heat reflecting surface 4a on the upper surface which has been made bright by sulfuric acid alumite treatment, etc., and a warm color 4b with a warm feeling by applying orange painting etc. on the lower surface. .

Hereinafter, the operation of the blind according to the present invention will be explained. In winter, the operating rope 10 shown in FIG. 1 is operated to pull up the auxiliary slat plate lifting cord 9 connected thereto.

Each auxiliary slat plate 4 is lifted by the lifting cord 9, and reaches from the intermediate position shown in FIG. 5 to the lower surface of the main slat plate 3 adjacent above as shown in FIG.

In this state, the upper surface of all the slat plates becomes only the heat-absorbing surface 3a, and each heat-absorbing surface absorbs solar heat and convection heats the air around the slat plate, contributing to indoor heating.

Also, at this time, warm colors 4b appear on the side surfaces of the slats in the room, giving a warm feeling to the occupants.

In the summer, contrary to the above, the sub-slat plate 4 is pulled down and brought into contact with the upper surface of the downwardly adjacent main slat plate 3.

(Figure 7). In this state, the upper surface of all the slat plates becomes only the heat reflecting surface 4a, and each reflecting surface reflects the global heat and contributes to cooling the room.

Also, at this time, a light color 3b that gives a refreshing feeling appears on the indoor side of the slat board, giving a cool feeling to the occupants.

In practice, the standard angle of incidence of sunlight in winter and summer is set, and the inclination angle of the slat plate is adjusted accordingly by rotating the slat plate tilting board 31, which is fixed to the slat plate tilting cord. It is sufficient to adjust and set 8.

In other words, Fig. 8 shows that since the angle of incidence of sunlight is small in winter, the slats are set at a constant angle with the main slats 3 facing upward to guide the absorbed heat into the room, and to direct the absorbed heat into the room while also directing the lower surface of the slats toward the indoor side. In addition, as shown in Figure 9, since the angle of incidence of sunlight is large in the summer, the slats are set at a constant angle with the sub-slats 4 facing upward. This shows a state in which the light is totally reflected, and the lower surface is directed toward the indoor side, giving a refreshing feeling with the light color 3b.

The above-mentioned switching of the top surface of the slat plate is done at the change of seasons between summer and winter.
In other words, you only have to do it twice in one move.

The sub-slat plate 4 is also provided with a tilting device and is formed to be rotatable, although this is because the sub-slat plate 4 is not used in the state shown in Fig. 5 (Fig. 5 is for understanding the present invention). This is to facilitate the movement of the main slat plate 3 which is set at a constant inclination above or below the sub-slat plate, and the sub-slat plate lifting cord pair 9 .9 has the same movement as the slat plate tilting cord pair 8.8.

In the above explanation, the upper surface of the main slat plate 3 is formed as a heat absorbing surface, and the upper surface of the sub slat plate 4 is formed as a heat reflecting surface, but these can also be reversed, and in that case, of course, each lower surface is also formed as a heat reflecting surface. It needs to be reversed.

The blind according to the present invention configured as described above can have different colors on the upper and lower surfaces of the slat plates with an extremely simple structure, and can be easily switched.

Especially in a series of solar blinds, it is basically important to use colors that emphasize function on the outside, and colors that give a warm feeling in the indoors in the winter and cool in the summer, but in the case of this invention, For this reason, it is possible to create any color tone for the interior of the room, and various combinations are possible.

Further, even when the blinds are not completely closed and allow sunlight to enter, the color tones on the outdoor side and the indoor side can be maintained in the same manner as described above.

Moreover, it has many advantages, such as being able to use the conventional blind mechanism without making any changes by simply adding a cord for lifting and lowering the sub-slats, and also having the light blocking function of a normal blind.
