Abstract

This utility model discloses a fine linen pleated window screen, relating to the field of window screens. Its key technical features are: it includes an outer layer and an inner layer, with a pleated layer between the two layers. The pleated layer includes horizontal pleats and vertical pleats, each with several light-blocking pleats. The light-blocking pleats on the horizontal pleats are perpendicular to those on the vertical pleats, and are horizontally positioned below them. By incorporating a pleated layer between the inner and outer layers, including horizontal and vertical pleats, this utility model effectively blocks direct sunlight from entering the room when the sun's altitude angle is high and sunlight intensity is also high, as sunlight travels downwards from high altitudes. This prevents the room from becoming hot and glaringly bright due to sunlight exposure. When sunlight intensity is low, it ensures indoor brightness, preventing the window screen from being too dark and causing the room to remain completely dark.

Description

Technical Field

[0001] This utility model relates to the field of window screens, and more specifically, to fine linen pleated window screens. Background Technology

[0002] Window screens are a type of fabric material used for windows, typically to keep out insects and prevent dust from entering the room.

[0003] While window screens can obstruct the view, they do not completely block sunlight, allowing the room to maintain a certain level of brightness. However, when the light intensity is too high, window screens often cannot effectively reduce the light intensity, resulting in excessively glaring sunlight filtering through them.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fine linen pleated window screen that can prevent excessive sunlight from passing through the window screen.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: the fine linen pleated window screen includes an outer layer and an inner layer, and a pleated layer is provided between the inner layer and the outer layer. The pleated layer includes horizontal pleats and vertical pleats. Both the horizontal pleats and the vertical pleats include a number of light-blocking pleats. The light-blocking pleats on the horizontal pleats are perpendicular to the light-blocking pleats on the vertical pleats. The light-blocking pleats on the horizontal pleats are arranged horizontally, and the horizontal pleats are located below the vertical pleats.

[0007] The present invention is further configured such that the orthographic projection area of ​​the longitudinal pleats on the outer surface layer is 1 / 2 of the orthographic projection area of ​​the transverse pleats on the outer surface layer.

[0008] The present invention is further configured such that: the outer surface layer is woven with a plurality of holes, the side of the outer surface layer away from the pleats is provided with an anti-aging coating, and the outer surface layer is woven from a plurality of anti-aging yarns.

[0009] The present invention is further configured such that: the inner surface layer is woven from several fine linen yarns and polyester organza yarns, wherein the warp yarns of the inner surface layer are polyester organza yarns and the weft yarns of the inner surface layer are fine linen yarns.

[0010] The present invention is further configured such that: the count of the fine linen yarn is 60, and the count of the polyester organ yarn is 80.

[0011] The present invention is further configured such that the weaving density of the pleated layer is 50-60 threads / inch.

[0012] In summary, this utility model has the following beneficial effects:

[0013] This invention features a pleated layer between the inner and outer surfaces. This pleated layer includes horizontal and vertical pleats. When the sun's altitude angle is low, the sunlight intensity is weak, and sunlight propagates towards the window from a lower position. The horizontal shading pleats on the horizontal pleats cannot effectively block the path of sunlight, allowing the weak sunlight to reflect onto the inner surface, ensuring indoor brightness and preventing the window screen from being too dark. When the sun's altitude angle is high, the sunlight intensity is also high. Sunlight propagates downwards from a high position and needs to pass through multiple shading pleats. Therefore, the horizontal shading pleats can effectively block sunlight with a high sun altitude angle, reducing the amount of strong sunlight passing through the window screen and preventing excessive sunlight intensity.

[0016] In the diagram: 1. Outer layer; 2. Inner layer; 3. Wrinkle layer; 4. Horizontal fold; 5. Vertical fold. Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: Fine linen pleated window screen, such as Figure 1 , Figure 2 As shown, the structure includes an outer layer 1 and an inner layer 2. A pleated layer 3 is provided between the inner layer 2 and the outer layer 1. The pleated layer 3 includes horizontal pleats 4 and vertical pleats 5. Both the horizontal pleats 4 and the vertical pleats 5 include several light-blocking pleats. The light-blocking pleats on the horizontal pleats 4 are perpendicular to the light-blocking pleats on the vertical pleats 5, and the light-blocking pleats on the horizontal pleats 4 are horizontally arranged. The horizontal pleats 4 are located below the vertical pleats 5. When the solar altitude angle is small, the sunlight intensity is weak, and the sunlight will propagate towards the window from a lower position. The horizontal light-blocking pleats on the horizontal pleats 4 cannot effectively block the path of sunlight propagation. This allows the soft sunlight to be reflected onto the inner surface 2, ensuring indoor brightness and preventing the room from being constantly dark due to excessive light blocking by the window screen. When the sun's altitude angle is large, the sunlight intensity is also large. As sunlight travels downwards from high places, the horizontal light-blocking folds on the horizontal pleats 4 can effectively block the path of sunlight directly into the room. Because when the angle of light is steep, sunlight will be blocked by multiple light-blocking folds at the same time. This can reduce strong sunlight passing through the window screen, prevent the room from becoming hot and glaring due to sunlight, and prevent excessive sunlight intensity passing through the window screen.

[0019] like Figure 1 , Figure 2As shown, the projected area of ​​the longitudinal pleats 5 on the outer surface layer 1 is half the projected area of ​​the transverse pleats 4 on the outer surface layer 1. The light-blocking pleats on the longitudinal pleats 5 are perpendicular to the horizontal plane, and the sunlight path is from top to bottom. Therefore, the sunlight path will not be blocked by multiple longitudinal light-blocking pleats. The longitudinal pleats 5 have better light transmission. The area of ​​the longitudinal pleats 5 is small, which makes the part of the window screen with good light transmission smaller. When the sun altitude angle is large, only 1 / 3 of the window screen can pass through the sunlight well. It can also ensure that a small amount of sunlight passes through the window screen when the sunlight is strong.

[0020] The outer layer 1 has several holes woven into it. The side of the outer layer 1 away from the pleated layer 3 is provided with an anti-aging coating. The outer layer 1 is woven from several anti-aging yarns. The holes woven into the outer layer 1 can increase the breathability and ventilation of the window screen, while also allowing a certain amount of sunlight to pass through the window screen into the room to provide lighting. The anti-aging coating is also a UV protection coating, which can form a film on the outer layer 1 to prevent UV rays from passing through, thus preventing the fabric in the window screen from being decomposed by UV rays. The anti-aging yarn is made of several twisted nylon fibers, which has good weather resistance and ensures the service life of the window screen.

[0021] The inner layer 2 is woven from several fine linen yarns and polyester organza yarns. The warp yarn of the inner layer 2 is polyester organza yarn, and the weft yarn is fine linen yarn. Polyester organza yarn has strong moisture absorption and UV protection properties, which increases the moisture absorption and UV protection of the window screen. The fine linen yarn is made of several flax fibers twisted together, which has good antibacterial properties, thus preventing bacterial growth.

[0022] The fine linen yarn has a count of 60, and the polyester organza yarn has a count of 80. Both the fine linen yarn and the polyester organza yarn have a relatively low thickness, resulting in larger gaps between the fibers, which ensures a certain degree of light transmission.

[0023] The weave density of the pleated layer 3 is 50-60 threads / inch. At this weave density, the pleated layer 3 is not too thick and will not completely block sunlight, but it can still block most of the sunlight, so that some sunlight is reflected on the side of the inner surface layer 2 facing the pleated layer 3. This ensures that sunlight can pass through the pleated layer 3 slightly when the light is weak.

[0024] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
