Description

[Detailed description of the invention] purpose of invention (Industrial application field) The present invention relates to the structure of a curtain.

(Prior Art) Curtains or blinds are used to prevent indoor areas from becoming hot due to direct sunlight and to ensure privacy within the room. It is convenient to have curtains or blinds that allow the outside to be seen from inside the room.

(Problems to be Solved by the Invention) Lace curtains are curtains that allow the outside to be seen from inside the room, but lace curtains do not have sufficient light-shielding properties.

On the other hand, although blinds have sufficient light-blocking properties, they completely block light, making it impossible to see outside from inside the room.

In addition, although the outside can be seen from inside the room in a semi-shaded state, the inside can also be clearly seen, making it impossible to ensure sufficient privacy.

Therefore, it is conceivable to use lace curtains and blinds together, but in that case, the installation of these would be partial or large-scale, and operation during use would be troublesome.

Therefore, an object of the present invention is to provide a curtain that has the excellent properties of both a lace curtain and a blind at the same time.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a pleat-like material in which horizontally elongated light-shielding portions and non-light-shielding portions are alternately connected in the vertical direction. We adopted a structure called curtains.

Note that the term "shading part" here refers not only to a planar member that does not allow any sunlight to pass through it, but also to a material that is so non-transparent that the outside world cannot be completely recognized through it, even if it allows a small amount of sunlight to pass through. means something that has

(Function) Since a pleat-like object is formed by the light-shielding part and the non-light-shielding part, if the curtain is installed near a window so that sunlight hits the light-shielding part, the sunlight that hits the light-shielding part will not be able to pass through it. Therefore, the back side will be in the shade. Since the non-shading area is located in the shade, sunlight does not enter the room through it. Therefore, it is not dazzling when looking outside through the non-shading part, and it is possible to see the outside through the non-shading part, and conversely, it is difficult to see into the room from the outside.

(Example) Next, an example embodying the present invention will be described based on FIGS. 1 to 6. In this embodiment, a curtain is constructed using a pleated fabric in which the densely woven portions serve as light-shielding portions and the coarsely woven portions serve as non-light-shielding portions.

As shown in FIG. 1, the curtain 24 of this embodiment is made of a woven fabric, and the woven fabric has densely woven portions 20 and coarsely woven portions 21 woven alternately. Both the dense portion 20 and the coarse portion 21 have a horizontally long rectangular shape,
An insertion hole 22 for inserting a curtain string, which will be described later, is provided at the center of both ends of each portion 20, 21.

Further, as shown in FIG. 2, the curtain 24 of this embodiment is bent near the boundary 6a between the dense portion 20 and the coarse portion 21, and is a pleated fabric having a zigzag shape in longitudinal section. The shape of the pleats is created after the fabric is treated with resin.
Since it is formed by hot pressing, it will last semi-permanently.

The upper end of the curtain 24 is held between the lower surface of the curtain box 23, which has an inverted U-shaped cross section, and an upper plate 25. Further, a lower plate 26 having a shape slightly smaller than the inner surface of the curtain box 23 is attached to the lower end, and serves to hang the curtain 24 down.

Between the curtain box 23 and the lower plate 26, two curtain strings 27 are inserted through the insertion holes 22 so as to sew both sides of the dense portion 20 and the coarse portion 21, This serves to adjust the inclination angle of the portion 21.

Also, when this curtain string 27 is pulled upward, the curtain 24
As shown in FIG. 3, it is stored in the curtain box 23.

The curtain 24 of this embodiment having the above structure is manufactured, for example, as follows.

First, according to a known method, a plain woven curtain fabric 6 having warp 17 and weft 18 made of 5-denier polyethylene terephthalate multifilament as shown in FIG. 4 is obtained. At this time, the density of the weave is, for example, 20
The rough part 21 should be about 10 meshes.

Next, one side of this curtain fabric 6 is subjected to sputtering treatment.

Sputtering is carried out by passing the curtain material 6 through a sputtering device having an argon gas atmosphere of 4.times.10@-4 Torr.

As shown in FIG. 5, the sputtering apparatus 1 used at this time is equipped with a bottomed cylindrical target 2 made of Ni-Cr alloy as a cathode in the center of the cylindrical part of a casing 3, and around the target 2 are eight It has a structure in which linear anodes 5 extending in the vertical direction of the book are arranged so as to be located on the same circumference with the target 2 at the center. A DC voltage of 50 to 1000 ports is applied between the target 2 and the anode 5. Note that a ring-shaped permanent magnet 4 is arranged inside the target 2.

Further, around the anode 5, six guide rollers 7 for guiding the curtain fabric 6 are arranged at equal intervals on the same circumference with the target 2 as the center, and there is a gap between two of the guide rollers. is provided with an auxiliary guide roller 8.

On the outside of the circumference where the guide roller 7 is arranged, on the side of the auxiliary guide roller 8, there is a supply roller 9 for supplying the curtain fabric 6 to the guide roller 7, etc., and a supply roller 9 for winding up the curtain fabric 6 after the sputtering process. A winding roller 10 is installed. The curtain fabric 1 is supplied from the supply roller 9 to one auxiliary guide roller 8 and then to the guide roller 7.
, and another auxiliary guide roller 8, and are sputtered while being sequentially guided.

Incidentally, an exhaust pipe 11 and a supply pipe 12 for supplying argon gas and oxygen gas are connected to the casing 3 to reduce the pressure inside the sputtering apparatus 1.

As shown in FIG. 6, metal M (N1-Cr alloy) is adhered to the surface of the sputtered curtain fabric 6 as a film having an average thickness of 300 angstroms.

Next, in order to make the curtain fabric 6 easier to make into pleated fabric, the fabric 6 is treated with resin, and the curtain fabric 6 is cut and processed to form the surrounding folded portions, attachment portions, and insertion holes 22. After sewing, etc., fold it in a zigzag shape near the boundary 6a between the dense part 20 and the coarse part 21,
When hot-pressed, a curtain fabric 6 having the vertical cross-sectional shape shown in FIG. 7 is obtained.

When the obtained curtain fabric 6 is attached to the curtain box 23, the curtain 24 having the structure shown in FIGS. 1 to 3 is completed.

Next, the functions and effects of this embodiment will be described.

As shown in FIG. 2, the curtain 24 of this embodiment is installed near a window in a room so that sunlight S hits the densely woven portion 20.

Then, since the gap between the warp threads or the weft threads is small in the dense portion 20, the sunlight S is blocked without passing through the dense portion 20, and the metal M is roughly attached to the surface of the dense portion 20. Therefore, sunlight S is reflected by that film. Therefore, the temperature rise in the room exposed to sunlight is suppressed.

On the other hand, since the rough portion 21 is shaded by the dense portion, sunlight S does not enter the room through it. Even if you look outside from the direction of arrow E from inside the room, you will not feel dazzled, and only the densely woven portion 20 will obstruct your vision, but you will be able to see outside through the coarsely woven portion 20. It becomes possible.

Conversely, even when looking into the room from the outside through the coarsely woven portion 21, it is difficult to see inside the room. Therefore, indoor privacy is maintained. - The present invention is not limited to the above embodiments, but includes, for example,
It can also be implemented in the following manner.

(1> Although the effects of the present invention can be obtained without attaching the metal M to the curtain fabric 6, it is better to attach the metal M to the curtain fabric 6 in order to further improve the light-shielding properties and heat-shielding properties.

(2) When depositing the metal M, various methods such as a vapor deposition method may be employed in addition to the sputtering method. Preferably, a sputtering method is recommended from the viewpoint of excellent adhesion between the metal M and the fibers.

The sputtering method is preferable if it is applied to the curtain fabric 6 from the viewpoints of higher productivity and no need to attach metal to excess parts. Moreover, sputtering can also be applied to the multifilament before it is made into the curtain fabric 6.

(3) The filament or curtain fabric 6 can be flame-retardantly treated.

(4) The fibers may be in the form of spun yarn, but in order to permanently hold the pleats, filaments with a strong so-called ``woven fiber stiffness'' are used.Furthermore, the curtain fabric 6 is made of a knitted fabric. However, in order to maintain the shape of the pleats and to better exhibit the effects of the present invention, a woven fabric is preferable.

This fabric includes any fabric that uses warp and weft yarns.

(5) In addition to the mode in which the two sections are alternately folded only at the boundary 6a between the dense portion 20 and the coarse portion 21 to form a pleat-like object, as shown in FIG. It is also possible to fold the center part of the rough part 21 in addition to the boundary 6a with the part 21.

(6) In addition to forming the dense portion 20 and the coarse portion 21 using a common warp thread, the dense portion 20 and the coarse portion 21 are woven separately and cut into appropriate widths, They can also be alternately connected to form one curtain fabric 6. The width of each portion 20 and 21 can also be changed as required.

(7) Metals that are roughly coated include gold, silver,
In short, any metal can be used as long as it can be attached to or coated with fibers, such as single metals such as iron, copper, nickel, chromium, and aluminum, or alloys containing these as components.

(8) The metal does not necessarily need to cover the entire surface of the fiber, and may cover only a part of it. Also, its thickness is 1
The thickness is approximately 00 to 1000 angstroms.

(9) A light-shielding resin plate can be used as the light-shielding part 20, and a colored transparent film, sheet, etc. can be used as the non-light-shielding part 21. These can be combined with textiles and the like.

Effects of the Invention As detailed above, the present invention exhibits the light-shielding properties inherent to curtains, and also has the excellent effect of allowing the outside to be seen from inside the room through the non-shading portion, and conversely making it difficult to see into the room from outside. demonstrate. As a result, it is possible to suppress the rise in temperature in the room and to ensure privacy in the room.
