Description

  The present invention relates to a awning sheet body, and more particularly, to a awning sheet body capable of transmitting sunlight with a desired degree of strength.

The sunshade is used in various places to attenuate sunlight, and various sunshade sheets used for the sunshade have been proposed (see, for example, Patent Document 1).
Patent Document 1 provides “a awning sheet material that is light and low in volume, has low light transmittance, can be used even in rain, and can be used for frequent folding” (Patent Document 1, Invention) In the detailed description, paragraph No. 0007), specifically, an aluminum metal layer is provided on at least one side of a base fabric made of a knit fabric as a sunshade sheet body. An awning sheet material, characterized in that a urethane-based resin film layer is provided on the outer surface of the sheet (Patent Document 1, Claim 1). According to such a sunscreen sheet disclosed in Patent Document 1, “In the above configuration, the aluminum metal layer is provided, so that the heat ray is reflected and it is cool when used for sunshade and can prevent sunburn. Furthermore, because it is based on knit fabric, it has a light and soft touch, and the aluminum metal layer in use is hardly damaged by the stretch and elasticity that are the characteristics of the knit. Since it is provided, it can be used not only in the sunshade but also in rainy weather. ”(Patent Document 1, paragraph number 0010 in the detailed description of the invention), thereby,“ Because an aluminum metal layer is provided on at least one side. The surface of this aluminum metal layer can reflect not only ultraviolet rays but also so-called heat rays such as visible rays and infrared rays, and it is cool when used for sunshade. In addition, it is notable for sun protection, which is a major cause of skin disorders such as skin spots, buckwheat, wrinkles, skin cancer, etc. It is also good for beauty.Because it is based on knitted fabric, it has a light and soft hand touch, and features of knit Due to its extensibility and elasticity, there is very little damage to the aluminum metal layer in use, and since the urethane resin film layer is provided on the outer surface, it can be used not only in the sun, but also in rainy weather. It can be widely used for parasols, especially umbrellas for sports such as golf, tents for general leisure, etc. "(Patent Document 1, paragraph number 0017 in the detailed description of the invention).

JP-A-6-134929 (for example, abstract, paragraph numbers 0001 to 0010, 0017, FIG. 1 etc.)

According to such an awning sheet body disclosed in Patent Document 1 (the awning sheet material in Patent Document 1), it is light and low in bulk, has low light transmittance, and can be used even during rain. Although it can form sunlight, it attenuates sunlight with a certain shading rate, so the intensity of sunlight that has passed through the shade sheet may not be comfortable (for example, sunlight When the intensity is high (for example, in summer), the intensity of sunlight that has passed is too strong, or when the intensity of sunlight is weak (for example, in winter), the intensity of sunlight that has passed may be too low. ).
Therefore, an object of the present invention is to provide a sunshade body in which the intensity of sunlight passing through the sunshade body is comfortable.

  A sunshade sheet body of the present invention (hereinafter referred to as “a sunshade sheet body” hereinafter) is a sunshade sheet body having both main surfaces, and is one of the two main surfaces. When the main surface is along a plane, the imaginary line segments that cross the one main surface are separated from each other by dividing lines that are perpendicular to the line segments on the one main surface. Passing through a plurality of areas forming the main surface, and the overall light blocking ratio of each of the plurality of areas decreases from the area existing on one end side of the line segment to the area existing on the other end side of the line segment It is a sheet body for sunshade.

The sunshade sheet body is a sunshade sheet body having both main surfaces, similar to the awning sheet material in Patent Document 1, and sunlight passes from one of the two main surfaces toward the other. This is to weaken the sunlight.
The sheet body for sunshade has a plurality of regions forming one main surface which is one of the two main surfaces. The area is defined by one or more dividing lines existing on the one main surface along a plane (if two or more dividing lines exist, the two or more dividing lines are parallel to each other). The surface is formed by dividing the surface (if the number of dividing lines is N, (N + 1) areas are formed), and the dividing line is a virtual crossing the main surface. It is perpendicular to the top one line segment. For this reason, the line segment passes through the plurality of regions forming the one main surface.
Then, the overall light shielding rate of each of the plurality of regions decreases from the region existing on one end side of the line segment to the region existing on the other end side of the line segment. Here, the “light shielding rate of the entire region” means the light shielding rate (R = (1−I / I0) × 100) in each part of the region, where I0 is the illuminance of incident light incident on one of the two main surfaces. Where I is the illuminance of the transmitted light transmitted to the other of the two main surfaces.)
By doing so, the strong sunlight passes through the region existing on one end side of the line segment and the weak sunlight passes through the region existing on the other end side of the line segment. In this case, strong sunlight is greatly reduced by being largely shielded from light. (E.g., strong sunlight in summer passes through an area on one end of the line and weak sunlight in winter passes through an area on the other end of the line. For example, the sun is sufficiently weakened in the summer and not so weak in the winter, so it is possible to obtain passing sunlight with a comfortable intensity throughout the seasons.)

In the present sun protection sheet, the plurality may be at least three.
In the plurality of regions forming the one main surface, the overall light shielding rate of each of the plurality of regions decreases from a region existing on one end side of the line segment to a region existing on the other end side of the line segment. Thus, as described above, the strong sunlight passes through the region existing on one end side of the line segment, and the weak sunlight passes through the region existing on the other end side of the line segment. The intensity of sunlight that has passed through is adjusted to a suitable one. For this reason, the larger the number of the regions (the plurality), the finer the light shading rate can be adjusted. Therefore, the intensity of the sunlight that has passed can be finely adjusted. Since there is a problem that it becomes complicated, it may be made a range in which these are compatible, preferably 3 or more, more preferably 4 or more, and preferably 10 or less, more preferably 8 or less.

In the sun protection sheet, a plurality of high light-shielding rate portions that are portions having a relatively high light-shielding rate, and a portion having substantially the same light-shielding rate that is relatively lower than the high light-shielding rate portion. A plurality of low light-shielding rate portions, and the ratio of each region of the low light-shielding rate portion to the high light-shielding rate portion is changed from the region existing on the one end side of the line segment to the other end side of the line segment. The overall light shielding rate decreases as it goes from the region existing on the one end side of the line segment to the region existing on the other end side of the line segment (hereinafter, “ High and low light shielding rate partial sheet body for sunshade ").
Various methods may be used so that the overall light blocking ratio of each of the plurality of regions decreases from the region existing on the one end side of the line segment to the region existing on the other end side of the line segment. For example, (1) when each region is formed of a resin material, the light shielding rate is changed depending on the type and amount of filler mixed in the resin material, or (2) a layer that absorbs or reflects sunlight in each region (3) including a plurality of high light-shielding rate parts and a plurality of low light-shielding rate parts, For example, the ratio of the low light shielding ratio to the high light shielding ratio in each of the plurality of regions may be changed to change the light shielding ratio.
In particular, the sun protection sheet body of (3) above includes a plurality of high light blocking ratio portions and a plurality of low light blocking ratio portions (the plurality of high light blocking ratio portions have substantially the same light blocking ratio, and a plurality of low light blocking ratio portions). All the rate portions have substantially the same light shielding rate, and the light shielding rate of the low light shielding rate portion is smaller than the light shielding rate of the high light shielding rate portion.) The ratio of the low light shielding rate portion to the high light shielding rate portion in each of the plurality of regions (The ratio of the area forming the one main surface. For example, if the area S2 occupies the low light-shielding ratio portion relative to the area S1 occupied by the high light-shielding ratio portion in a certain region, (S2 / S1)). By increasing from the region existing on the one end side of the line segment to the region existing on the other end side of the line segment, the overall light blocking rate is changed from the region existing on the one end side of the line segment to the line segment. To go to the area on the other end If to reduce is, it is possible to easily configure the sheet member for keeping off today by varying the ratio by two parts with high shading rate portion and a lower light blocking ratio portion.

High and low light blocking ratio part In the sun protection sheet body, the high light blocking ratio part has a light blocking material for attenuating or blocking sunlight, and the low light blocking ratio part has no light blocking material, and both the main surfaces May be formed (hereinafter referred to as “opening sunshade sheet”).
By doing so, the low light blocking ratio portion does not require a light blocking material, and can be formed by the opening connecting the two main surfaces, so that no member for forming the low light blocking ratio portion is required today. The shade body can be constructed at a low weight and at a low cost, and ventilation can be obtained between the two main surfaces through the opening, so that the use of the shade body is made comfortable.
In addition, what is necessary is just to attenuate or block sunlight as a light shielding material.

In the opening sunshade sheet, the light shielding material includes an elongated light shielding longitudinal member, and the plurality of light shielding longitudinal members are arranged along the one main surface so that the longitudinal directions thereof are substantially parallel to each other. (Hereinafter, referred to as a “light shielding longitudinal member today's sunshade sheet”).
By using the light shielding material including the elongated light shielding longitudinal member as described above, and arranging the plurality of light shielding longitudinal members along the one main surface so that the longitudinal directions thereof are substantially parallel to each other, the high light shielding ratio portion is regularly arranged. And it can form easily. The elongated light-shielding longitudinal member refers to the maximum dimension D1 (dimension along the longitudinal direction) of the light-shielding longitudinal member and the maximum dimension D2 among the dimensions along the direction perpendicular to the direction of the maximum dimension D1. The ratio (D1 / D2) is preferably 10 or more, more preferably 200 or more, and most preferably 400 or more (although there is no particular upper limit, it is usually 2000 or less).

In the light shielding longitudinal member, the sheet for awning may be such that the longitudinal direction of the light shielding longitudinal member and the line segment are substantially orthogonal to each other on the one main surface.
In this way, the longitudinal direction of the light shielding longitudinal member (the direction along the maximum dimension D1) and the line segment are substantially orthogonal to each other on the one main surface, thereby changing the arrangement of the light shielding longitudinal member along the line segment. By a simple method, the overall light shielding rate of each region can be configured to decrease from the region existing on one end side of the line segment to the region existing on the other end side of the line segment.

In the light shielding longitudinal member sheet for sun protection, a gap formed between the plurality of light shielding longitudinal members may constitute a low light shielding rate portion.
By doing this, the area ratio of the gap formed between the plurality of light shielding longitudinal members (the area forming the one main surface of the light shielding longitudinal member and the one of the gaps formed between the light shielding longitudinal members) The ratio of the area forming the surface) is changed in each region, so that the overall light blocking ratio of each region is changed from the region existing on one end side of the line segment to the region existing on the other end side of the line segment. It can be easily configured to decrease as it goes.

In the light shielding longitudinal member of the present awning sheet body, the light shielding longitudinal member may have a strip shape elongated in the longitudinal direction constituting both main surfaces of the sheet body.
In this way, if the elongated light-shielding longitudinal member has a strip shape elongated in the longitudinal direction, and the elongated strip-shaped light shielding longitudinal member constitutes the main surfaces of the sun protection sheet body, By arranging the thin strips having both substantially parallel edges so that the edges are along each other, it is possible to efficiently form the sun protection sheet.

In the sheet for a light-shielding longitudinal member, the plurality of light-shielding longitudinal members have substantially the same length, and the plurality of light-shielding longitudinal members are located at substantially the same position in the longitudinal direction so that the one main surface is rectangular. May be substantially formed.
In this way, by arranging a plurality of light-shielding longitudinal members having substantially the same length (dimension along the longitudinal direction) so that both ends thereof are at substantially the same position in the longitudinal direction, the one main surface is substantially formed in a rectangle. It is possible to form a convenient sunshade having a substantially rectangular main surface (the part where the sunshade such as a window or a building entrance is installed is generally rectangular, If the main surface is roughly rectangular, it can be used better with improved versatility.)

The light shielding longitudinal member of the present awning sheet body may have a support wire that binds and supports a plurality of light shielding longitudinal members.
In this way, by arranging and supporting a plurality of light shielding longitudinal members by supporting wire members, the plurality of light shielding longitudinal members can be easily and reliably arranged along the one main surface so that their longitudinal directions are substantially parallel to each other. Can do.

The present invention also provides an awning (hereinafter referred to as “today's awning”) using a sheet body for awning.
That is, the sunshade is a sunshade that uses the sunshade sheet body described above, and the sunshade having the sunshade sheet body is a strong member of the sunshade sheet body. If sunlight passes through the region existing on the one end side of the line segment and weak sunlight passes through the region existing on the other end side of the line segment, strong sunlight is greatly shielded. However, since the weak sunlight is not shielded so much and is not so weak, the intensity of sunlight can be adjusted to a suitable one.

The sunshade may have an attachment portion that is formed in the vicinity of the edge portion of the one main surface existing on the one end side of the line segment and attaches and supports the sunshade to a support.
In this way, the attachment portion for attaching and supporting the sunshade to the support is formed in the vicinity of the edge portion of the one main surface existing on the one end side of the line segment of the sunshade sheet member included in the sunshade. Then, when the mounting portion is attached to a support and the sunshade is supported, the one end side is present at the upper side and the other end side is present at the lower side, and the strong sunlight emitted from the high altitude sun in the summer is the above-mentioned The weak sunlight emitted from the sun having a low altitude in the winter passes through the region existing on the one end side of the line segment and passes through the region existing on the other end side of the line segment. As a result, today's awning allows the sunlight to pass sufficiently weak in the summer and passes through the sunlight without weakening in the winter, so that it is possible to obtain passing sunlight with a comfortable intensity throughout the seasons.

  Embodiments of the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto.

  FIG. 1 is a front view showing a sunshade (awning) 11 according to an embodiment of the present invention (showing a vertical direction with respect to a surface irradiated with sunlight), and FIG. 2 is an enlarged view of a portion surrounded by a dotted line A in FIG. 1, FIG. 3 is a sectional view taken along line FF in FIG. 2, and FIG. 4 is an enlarged view of a portion surrounded by a dotted line B in FIG. 5 is a sectional view taken along line GG in FIG. 4, FIG. 6 is an enlarged view of a portion surrounded by a dotted line C in FIG. 1, and FIG. 7 is a sectional view taken along line JJ in FIG. 8 is an enlarged view of a portion surrounded by a dotted line D in FIG. 1, and FIG. 9 is a sectional view taken along the line KK in FIG. The sunshade 11 will be described with reference to FIGS.

The awning 11 is generally formed of a flexible material that can follow a plane. Specifically, the awning 11 is attached to the awning body 13 and the awning body 13 having a front surface 13a and a back surface 13b that are substantially the same rectangle. And a locking portion 19 provided.
The awning body 13 includes a plurality of elongated strip-shaped film pieces 15 whose longitudinal direction extends in the film continuous direction L, and support yarns 17 that interweave and support (engage) the plurality of film pieces 15. And the plurality of film pieces 15 are supported by the support yarn 17 so that their longitudinal directions are substantially parallel to each other (all of the plurality of film pieces 15 have their longitudinal directions parallel to the film continuous direction L). In addition, any surface of the film piece 15 forms a surface 13a, and any back surface of the film piece 15 is supported so as to form a back surface 13b.

  The plurality of film pieces 15 are the same in shape and material (the film pieces 15 are the same), and are formed of a thin film made of a synthetic resin whose main surfaces are elongated rectangles. ing. The film piece 15 hardly transmits sunlight incident from the front surface (surface that forms the front surface 13a) to the back surface (surface that forms the back surface 13b) (specifically, the light shielding rate of sunlight (according to the JIS L 1055A method). The measured value is about 99.8%, and various methods can be used to change the light shielding rate of the film piece 15. For example, the filler kneaded into the resin material forming the film piece 15 Depending on the type and amount of (filler), the shading rate is changed, or a layer that absorbs or reflects sunlight is provided on the surface of the film piece 15 (the layer is provided by printing, or an aluminum foil is applied The shading rate can be changed by attaching to the surface).

  In detail, the support yarn 17 has individual yarns circulated around each film piece 15 (the yarn abuts on the front surface (forming the front surface 13a) and the back surface (forming the back surface 13b) of the film piece 15, 15), and a thread wound around one of a pair of film pieces 15 adjacent to each other in the vertical direction (indicated by an arrow Z in the figure, perpendicular to the film continuous direction L); The plurality of film pieces 15 are supported so as to be continuous in the vertical direction Z by being twisted between the pair of film pieces 15 and the yarn wound around the other of the pair of film pieces 15. FIG. 10 is a diagram illustrating details of the support yarn 17, and details of the support yarn 17 will be described with reference to FIG. 10. FIG. 10A is an enlarged view (partially enlarged view of FIG. 2) of the film pieces 15a and 15b whose longitudinal direction is along the film continuous direction L, and FIG. FIG. A thread 17a is circulated around the film piece 15a, and a thread 17b is circulated around the film piece 15b. And the connection part 17c where these thread | yarns 17a and the thread | yarn 17b were put together was formed between the film pieces 15a and 15b, and the film pieces 15a and 15b are supported so that it may continue in the up-down direction Z. Thus, the film pieces 15 adjacent to each other in the up-down direction Z are supported so as to be continuous in the up-down direction Z by the yarns fixed around each other being supported between the film pieces 15.

  The locking portions 19 include four upper locking portions 19a attached at substantially equal intervals along one edge 13c (here, the upper edge) which is one side of the rectangle formed by the front surface 13a and the back surface 13b of the sunshade body 13. And four lower locking portions 19b attached at substantially equal intervals along the other edge 13d (here, the lower edge) substantially parallel to the one side of the rectangle. Each of these eight locking portions 19 is here formed by a grommet that forms a through hole that connects the front surface 13a and the back surface 13b. The sun protection 11 is supported by locking the upper locking portion 19a formed along the one edge 13c and the lower locking portion 19b formed along the other edge 13d to some support. Can be used.

The awning body 13 includes a first portion 21 that is present at the top in the vertical direction Z, a second portion 31 that is formed below the first portion 21 so as to be adjacent to the first portion 21, A third portion 41 formed below the second portion 31 so as to be adjacent to the second portion 31, and a fourth portion 51 formed below the third portion 41 so as to be adjacent to the third portion 41 (mostly Lies below). The difference between the first portion 21 to the fourth portion 51 is the arrangement of the film piece 15. Specifically, the first portion 21 has the film piece 15 arranged in the vertical direction Z without a gap. On the other hand, in the second part 31 to the fourth part 51, the film piece 15 is not arranged, so that a slit 18 (a gap elongated in the film continuation direction L. The shape and size is almost the same as that of the film piece 15 of 1) is formed. The difference between the second portion 31 and the fourth portion 51 is the formation ratio of the slit 18 along the vertical direction Z.
Specifically, along the vertical direction Z, three film pieces 15 are arranged between the pair of adjacent slits 18 in the second portion 31, and between the pair of adjacent slits 18 in the third portion 41. Two film pieces 15 are arranged, and in the fourth portion 51, one film piece 15 is arranged between a pair of adjacent slits 18. As a result, the ratio of the slits 18 to the unit area of the surface 13a increases as going to the first part 21, the second part 31, the third part 41, and the fourth part 51 (specifically, the ratio is The first portion 21 is 0%, the second portion 31 is about 25%, the third portion 41 is about 33%, and the fourth portion 51 is about 50%.)
Thus, the ratio of the slit 18 occupying the unit area of the surface 13a is different in the first portion 21, the second portion 31, the third portion 41, and the fourth portion 51, so that the first portion 21, the second portion 31, The third part 41 and the fourth part 51 have different sunlight blocking rates. That is, as described above, the sunlight shading rate of the film piece 15 is about 99.8%, and the slit 18 is about 0%. Therefore, the ratio of the slit 18 in the unit area of the surface 13a is different. The light blocking rate of the entire first part 21, second part 31, third part 41, and fourth part 51 is different. For example, assuming that the sunlight shielding rate of the film piece 15 is X% (as described above, about 99.8% here), and the ratio of the slits 18 to the unit area of the surface 13a is y%, 0% × y / 100 + X% × (100−y) / 100 = (X (1−y / 100))%.

FIG. 11 shows an example of a method of using the sunshade 11, and the method of using the sunshade 11 will be described with reference to FIG. 11.
First, the sunshade 11 is supported on a support (not shown). Specifically, the upper locking portion 19a formed along the one edge 13c and the lower locking portion 19b formed along the other edge 13d are locked to a support (not shown) (upper portion). The locking portion 19a is locked upward and the lower locking portion 19b is positioned downward).
At this time, when the sun 201 at a high altitude (for example, summer) irradiates very strong sunlight, and does not want to receive sunlight from the sun 201, the sun 201 as viewed from the position of the user 301 The position of the awning 11 is determined so that the first portion 21 exists between the user 301 and the user 301. As a result, the first portion 21 does not allow sunlight to pass through, so the user 301 does not receive sunlight.

When the sun 203 (for example, early summer) at a slightly lower altitude irradiates strong sunlight, the sun 203 is viewed from the position of the user 301 when the sun 201 is hardly received. The position of the sunshade 11 is determined so that the second portion 31 exists between the user 301 and the user 301. As a result, the second portion 31 hardly transmits sunlight, so that the user 301 does not receive strong sunlight.
When the sun 205 (for example, spring and autumn) at a position where the altitude is lowered irradiates slightly strong sunlight, when the sun 205 from the sun 205 is slightly weakened, the sun 205 is viewed from the position of the user 301. The position of the awning 11 is determined so that the third portion 41 exists between the user 301 and the user 301. As a result, the third portion 41 allows the sunlight to pass through slightly weakened, so that the user 301 can receive the slightly weakened sunlight.
When the sun 207 at a sufficiently low altitude (for example, winter) irradiates weak sunlight, the sun 207 and the user are viewed from the position of the user 301 when the sun 207 sufficiently receives sunlight. The position of the sunshade 11 is determined so that the fourth portion 51 exists between the current part 301 and the third part 51. As a result, the fourth portion 51 allows sunlight to pass through without weakening so that the user 301 can receive sufficient sunlight.

As described above, the sunshade 11 has the first portion 21, the second portion 31, and the second portion so that the transmittance of sunlight increases from the one edge 13 c (upper edge) side toward the other edge 13 d (lower edge). Since the 3 part 41 and the 4th part 51 are formed, the sun from the high sun where the intensity | strength of sunlight is large is installed by setting the one edge 13c as an upper edge and setting the other edge 13d as a lower edge like FIG. Light can be attenuated or blocked greatly, and sunlight from a low sun with low sunlight intensity can be transmitted well, so that the user 301 can be made comfortable.
Further, the sunshade 11 is different from the first portion 21, the second portion 31, the third portion 41, and the fourth portion 51 by changing the ratio of the slits 18 occupying the unit area of the surface 13 a to the first portion 21, Since the sunlight shading rate of each of the second part 31, the third part 41, and the fourth part 51 is changed, ventilation is obtained through the slit 18 between the front surface 13a and the back surface 13b. For this reason, even if the sunshade 11 is installed today, a desired ventilation can be obtained, and the user 301 is made comfortable from this point as well (particularly, the ratio of the slits 18 to the unit area of the surface 13a is at a low position). Since it is large in the 4th part 51 and the 3rd part 41, the wind which blows a low position along the ground surface can pass the 4th part 51 and the 3rd part 41 well, and a comfortable ventilation can be obtained.

FIG. 12 is a front view of the awning body 13 for explaining the divided straight lines and the line segments (as viewed from the same position as in FIG. 1), and a first part for easy illustration and understanding. 21, the patterns of the second portion 31, the third portion 41, and the fourth portion 51, the illustration of the locking portion 19, and the like are omitted. In addition to FIGS. 1 to 11 described above, the awning body 13 will be described with reference to FIG.
The sunshade body 13 of the sunshade 11 is a awning sheet having both main surfaces (here, the front surface 13a and the back surface 13b), and is one of the main surfaces (the front surface 13a and the back surface 13b). When the main surface (for example, the surface 13a) is set along a plane (FIGS. 1 and 12), an imaginary line segment 401 crossing the one main surface (surface 13a) is formed on the one main surface (surface 13a). A plurality of (here, four) regions (here, the first portion) forming the one main surface (surface 13a), which are divided from each other by divided straight lines 501a, 501b, and 501c that are straight lines perpendicular to the line segment 401 21, the second part 31, the third part 41, and the fourth part 51, the first part 21 and the second part 31 are divided by a virtual dividing straight line 501 a, and the second part 31 and the third part 41 is divided by a virtual dividing line 501b. The third part 41 and the fourth part 51 are divided by a virtual dividing line 501b), and the plurality of regions (first part 21, second part 31, third part 41, 4th part 51) The shading rate of each whole decreases as it goes from the area | region which exists in the one end 401a side of this line segment 401 to the area | region which exists in the other end 401b side of this line segment 401 It is a sheet body. Specifically, the light shielding rate of sunlight of the film piece 15 is X%, and the ratio of the slits 18 in each region (here, the first portion 21, the second portion 31, the third portion 41, and the fourth portion 51) is set. If y%, the light shielding rate (X (1-y / 100))% is obtained, so that y = 0% in the first portion 21 and therefore X%, and in the second portion 31, y = about 25%. 0.75X%, so that in the third portion 41 y = about 33%, so 0.67X%, and in the fourth portion 51 y = about 50%, so 0.5X%. . Therefore, the overall light shielding rate X% of the first portion 21> the overall light shielding rate 0.75X% of the second portion 31> the overall light shielding rate 0.67X% of the third portion 41> the overall light shielding of the fourth portion 51.
