Here, the "fractal structure" refers to a structure having a plurality of clusters, in which the clusters form a hierarchical structure, and the shapes of the clusters belonging to each hierarchy are similar to each other. The Sierpinski tetrahedron is known as one of such self-similar solid figures.
Since the awning member embodying such a fractal structure itself has an extremely complicated shape, it will be described in detail below based on the description of Patent Document 2.

As shown in an enlarged view in FIG. 20, the four dihedrals 11, 12, 13, and 14 constituting the basic element 2 (the same applies to the other basic elements 3, 4, and 5) have the same shape, and each of them has the same shape. The face pieces 11, 12, 13, and 14 are composed of small triangular plate portions 11a, 12a, 13a, and 14a forming the front surface and small triangular plate portions 11b, 12b, 13b, and 14b forming the side surfaces.

The first dihedral 11 extends diagonally upward from the intersections of the lower sides 21 and 22 in the left-right and front-rear directions that are located on the horizontal plane and form two sides of a square, and has a ridgeline R. It consists of a common side 23 to be formed, and upper sides 24 and 25 on the front side and the back side connecting the upper end portion of the common side 23 and the end portions of the lower sides 21 and 22.

The second dihedral body 12 has a left-right lower side 21 in which the left-right lower side 21 of the first dihedral 11 is extended in the left-right direction and a front-back parallel to the front-back lower side 22 of the first dihedral body 11. The lower side 22 in the direction, the common side 23 parallel to the common side 23 of the first dihedral body 11, and the front side and the back side parallel to the upper sides 24 and 25 of the front side and the back side of the first dihedral body 11, respectively. It consists of upper 24 and 25 sides.

The third dihedral body 13 has a front-rear lower side 22 in which the front-rear lower side 22 of the first dihedral body 11 is extended in the front-rear direction, and left and right parallel to the left-right lower side 21 of the first dihedral body 11. The lower side 21 in the direction, the common side 23 parallel to the common side 23 of the first dihedral body 11, and the front side and the back side parallel to the upper sides 24 and 25 of the front side and the back side of the first dihedral body 11, respectively. It consists of upper 24 and 25 sides.

The fourth dihedral 14 has a common side 23 in which the common side 23 of the first dihedral 11 is extended diagonally upward and a front side 24 in which the upper side 24 on the front side of the second dihedral 12 is extended diagonally upward. The upper side 24 on the side, the upper side 25 on the back side where the upper side 25 on the back side of the third dihedral 13 is extended diagonally upward, and the left-right side parallel to the lower side 21 in the left-right direction of the first dihedral body 11. It consists of a lower side 21 and a lower side 22 in the front-rear direction parallel to the lower side 22 in the front-back direction of the first dihedral body 11.

In FIG. 20, the small triangular plate portions 11a, 12a, 14a forming the front surfaces of the first, second, and fourth dihedral bodies 11, 12, and 14 are on the same plane (front surface) with respect to the front surface. Since the small triangular plate portion 12b forming the side surface of the second dihedral body 12 is bent toward the bottom surface, a triangular small triangular through hole 15 is formed on the front surface of the basic element 2. There is.
Further, the small triangular plate portions 11b, 13b, 14b forming the side surfaces of the first, third and fourth dihedral bodies 11, 13 and 14 are on the same plane (side surface), and the side surfaces thereof. Since the small triangular plate portion 13a forming the front surface of the third dihedral body 13 is bent toward the bottom surface, a triangular small triangular through hole 15 is formed on the side surface of the basic element 2.
In this way, the basic element 2 is for the dihedral body portion in which the two middle triangular plate portions 2a and 2b having the small triangular through holes 15 in the central portion are joined via the ridge line R and the middle triangular plate portions 2a and 2b. It has a dihedral shape consisting of small triangular plate parts (protruding parts) 12b and 13a bent toward the bottom surface.

In the awning member 1 composed of the four basic elements 2, 3, 4, 5, the middle triangular plate portions 2a, 3a, 5a forming the front surfaces of the first, second, and fourth basic elements 2, 3, 5 are The middle triangular plate portion 3b, which is on the same plane (front surface) and forms the side surface of the second basic element 3, is bent toward the bottom surface with respect to the front surface, so that the large triangular portion 1a on the front surface is bent. Is formed with a triangular middle triangular through hole 6.
Further, the middle triangular plate portions 2b, 4b, and 5b forming the side surfaces of the first, third, and fourth basic elements 2, 4, and 5 are on the same plane (side surface), with respect to the side surfaces. Since the middle triangular plate portion 4a forming the front surface of the third basic element 4 is bent toward the bottom surface, a triangular middle triangular through hole 6 is formed in the large triangular portion 1b on the side surface. ..
As a result, the awning member molded product 1 has a dihedral body portion in which two large triangular plate portions 1a and 1b having a middle triangular through hole 6 in the central portion are joined via a ridge line R, and a large triangular plate portion 1a, It has a dihedral shape consisting of a middle triangular plate portion (protruding portion) 3b and 4a bent toward the bottom surface with respect to 1b.

Therefore, the awning member 1 is regarded as a basic element, and four of them are used and arranged in the same manner as the above basic elements 2, 3, 4, and 5, so that the awning member 1 is arranged horizontally, front-back, and vertically. A awning block that is an assembly of the member 1 can be obtained, and a awning of a required size can be obtained by appropriately increasing the number of awning blocks to be used.

When forming a awning using this awning member 1, a large number of awning blocks in which four awning members 1 are connected are prepared, and each awning block is assembled to a rectangular frame member in advance to form a awning unit. It is formed.
Further, the awning is formed by placing and fixing the plurality of awning units on the foundation frame supported by the plurality of legs.

By directing the ridgeline R of each awning member 1 included in the awning block to the south side, the sun's rays are blocked by the awning member 1, so that the awning effect can be exhibited.
Further, since a large number of triangular through-hole portions are formed in each awning member 1 and the light-shielding surfaces are dispersedly arranged in the three-dimensional space, the light-shielding surfaces are distributed through the gaps provided between the light-shielding surfaces. It is possible to quickly release heat into the air.

However, in the above prior art, the Sierpinski tetrahedron is used as a light-shielding surface to block the through-hole portion when viewed from a specific direction, but when the Sierpinski tetrahedron deviates from a specific direction, that is, the sun at noon. When trying to block the light to the maximum, the sunlight leaking from the through-hole portion increases in the time zone outside noon such as 11:00 and 13:00, and the awning performance deteriorates.
Also, if you try to maximize the light blocking performance at the end of July or early August when the sunlight is severe, the light leaked from the through hole will increase during the period before mid-July and after mid-August. The awning performance is reduced.

In order to solve the above problems, it is an object of the present invention to provide a awning structure in which the awning performance does not easily deteriorate even when the sunlight is strong or the season is different.

In order to achieve the above object, in the awning according to claim 1, a plurality of light-shielding surfaces and a plurality of gaps are three-dimensionally arranged, and each of the above-mentioned gaps is arranged behind when observed from a predetermined light-shielding angle. It is a awning with a plurality of awning blocks in which a plurality of awning members having a structure that looks almost blocked by each of the light-shielding surfaces are arranged in a certain direction, and the awning member is circular or. It is formed by using a plurality of curved circular members in which an elliptical plate material is curved, arranging the curved circular members so that their respective bending directions are aligned, and connecting the ends of each other. It is a feature.

Further, the awning according to claim 2 is the awning according to claim 1, and further, a plurality of awning units in which the above-mentioned awning blocks are assembled to a frame material with their curved concave surfaces aligned in a certain direction, and a plurality of awning units. It is characterized by having a support structure that supports each awning unit at a predetermined height from the ground.

Further, the awning according to claim 3 is the awning according to claim 1, and further, the awning block is a plurality of vertically placed units in which each curved concave surface is aligned in a certain direction and a plurality of awnings are assembled to a frame material. The above-mentioned vertical unit is provided with a plurality of inverted units assembled on the frame material with the awning block turned upside down, and a support structure for supporting each vertical unit and the inverted unit at a predetermined height from the ground. And the inverted units are characterized in that they are arranged alternately on the support structure.

The awning according to claim 4 is the awning according to claim 2 or 3, and further, each awning block is placed and fixed at a predetermined inclination angle with respect to the ground between the frame material and the support structure. It is characterized in that a tilting means is provided for the purpose.
The tilting means includes, for example, a substrate arranged on the upper part of the support structure, a movable plate on which the unit of the awning member is placed and fixed, and the movable plate rotatably fixed to one end of the substrate. It consists of a hinge and a spacer interposed between the substrate and the movable plate, and by changing the height of the spacer, the tilt angle of the movable plate and the unit of the awning member can be arbitrarily adjusted. The ones that have been made are applicable.

In the awning according to the present invention, the curved circular member forming the light-shielding surface has a circular or elliptical shape literally surrounded by a curved line, and bulges between the ends of the curved circular members arranged above and below. It has a structure in which parts overlap.
Therefore, as compared with the light-shielding surface of the conventional awning member surrounded by a straight line, it is possible to effectively alleviate the deterioration of the light-shielding performance due to the time and season deviation.

As shown in FIGS. 1 to 3, the awning according to the present invention is configured by combining a plurality of curved circular members 50 in which an elliptical plate material is curved around a short axis (minor diameter). The convex surfaces 51 of each curved circular member 50 are aligned so as to face the same direction.

As shown in FIG. 1, on top of (A) in which the long-axis ends of the pair of curved circular members 50 are joined to each other, (B) in which the short-axis ends of the pair of curved circular members 50 are joined to each other. Both ends of the long axis of each curved circular member 50 arranged above are joined near both ends of the short axis of each curved circular member 50 arranged below, that is, four curved circular members. The basic building block 52 is formed by three-dimensionally connecting the members 50.

This basic constituent block 52 is a "sunshade member" which is the smallest unit for constructing a sunshade.
In FIG. 2, the pair of curved circular members 50 arranged on the lower side are provided with a satin pattern for convenience to differentiate them from the curved circular members 50 arranged on the upper side. The black dots in the figure indicate the joints.

The convex surface 51 or the concave surface 56 of the curved circular member 50 included in each basic constituent block 52 functions as a light-shielding surface for awning.
As shown in FIG. 2, a gap α is generated between the pair of curved circular members 50 arranged on the upper side, but when observed from a plane, the convex surface of the curved circular member 50 arranged on the lower side. The gap α is shielded by 51.
Further, as shown in FIG. 3, there is a gap β due to the curvature between the curved circular member 50 arranged on the upper side and the curved circular member 50 arranged on the lower side.

The material of the curved circular member 50 is not particularly limited, and is formed of a synthetic resin, a metal such as aluminum, wood, or the like.
Instead of the elliptical curved circular member 50, a circular plate material can be used and curved around its diameter to form a curved circular member.

The joining method of each curved circular member 50 is not particularly limited, and adhesion, welding, or the like can be selected depending on the material.
Further, in the case of a synthetic resin, it is also possible to form a basic constituent block 52 in a state where each curved circular member 50 is connected from the beginning by injection molding.

When the light-shielding surface has an elliptical shape, the range of major axis: minor axis = 2: 1 to 1: 1 (circle) is preferable, and 3: 2 is more preferable.
Since the sun moves from east to west, if the long axis is set in the east-west direction, the light-shielding area of the ground will increase.
If the long axis is too large, the light-shielding surfaces will not overlap each other in the north-south direction, and direct sunlight will be more likely to enter when the seasons change and the solar altitude changes.

As for the curved shape of the light-shielding surface, the ratio of the linear length in the long axis direction to the height of the central portion is preferably 2: 1 to 4: 1, and more preferably 3: 1.
If it is smaller than 2: 1, it will be close to a flat surface, and air convection is unlikely to occur, so the temperature will rise. If it is larger than 4: 1, direct sunlight is likely to be incident when the season is out of midsummer and the solar altitude changes.

By combining the basic building blocks 52 according to a certain rule, a large-scale awning block having a fractal (self-similar) structure is formed.
First, as shown in FIG. 4 (a), by combining the four basic constituent blocks 52, as shown in FIG. 4 (b), a medium-sized block 53 having 16 curved circular members 50 is formed. It is formed.

Specifically, on top of (C) where the long axis ends of the curved circular members 50 arranged under the pair of basic constituent blocks 52 are joined to each other, the upper side of the other pair of curved circular members 50. (D) is arranged by joining the short axis ends arranged in the above, and both ends of the long axis of each curved circular member 50 arranged above are short of each curved circular member 50 arranged below. The medium-sized block 53 is joined near both ends of the shaft.

Further, as shown in FIG. 5 (a), by combining four medium-scale blocks 53, as shown in FIG. 5 (b), a large-scale block 54 provided with 64 curved circular plate members can be obtained. It is formed.

Specifically, on top of (E) where the long axis ends of the curved circular members 50 arranged at the bottom of the pair of medium-scale blocks 53 are joined to each other, the top stage of the other pair of medium-scale blocks 53. (F) in which the short-axis ends of the curved circular members 50 arranged in the above are joined to each other is arranged.
Next, both ends of the long axis of the curved circular member 50 arranged at the bottom of each upper medium-sized block 53 are placed on the uppermost stage of each of the lower medium-sized blocks 53. A large-scale block 54 is completed by joining near both ends of the short axis.

A protrusion 55 with a hole is provided at the long axis end of each curved circular member 50 arranged at both ends of the lowermost stage of the large-scale block 54.
Similarly, a protrusion 55 with a hole is also provided at the short shaft end of each curved circular member 50 arranged at both ends of the uppermost stage of the large-scale block 54.
These perforated protrusions 55 can be attached after the formation of the large-scale block 54, but curved circular members 50 in which the perforated protrusions 55 are previously formed at the long-axis end or the short-axis end can also be used. ..

6 to 8 are 3D images of the large-scale block 54 (however, for convenience of illustration, the holed protrusion 55 is omitted).
As shown in FIG. 6, when observed from a plane, the large-scale block 54 has almost no gap, and the gap between the basic constituent blocks 52 arranged on the upper side is a light-shielding surface of the basic constituent block 52 arranged on the lower side. It can be understood that it is almost completely closed by (the convex surface 51 of the curved circular member 50).

On the other hand, as shown in FIG. 7, when the viewpoint is slanted, it can be seen that a large number of gaps 57 exist between the curved circular members 50 or between the basic constituent blocks 52.
Further, as shown in FIG. 8, when the large-scale block 54 is observed from the lateral direction, a large number of large gaps 57 exist between the curved circular members 50 or between the basic constituent blocks 52, and sufficient air permeability is ensured. You can see that there is.

In the present invention, the large-scale block 54 may be used in the same orientation as shown in FIG. 6 or may be used in an inverted state. Therefore, the former is referred to as a normal block 60 and the latter is referred to as an inverted block. By calling it 61, the two will be distinguished from now on.

FIG. 9 is a 3D image showing the inverted block 61, in which a light-shielding surface is formed by the concave surface 56 of each curved circular member 50.
At the uppermost stage of the inverted block 61, eight curved circular members 50 having long shaft ends connected to each other are arranged. Further, at the lowermost stage, eight curved circular members 50 in which the ends of the short shafts are connected to each other are arranged.

By using a plurality of the large-scale blocks 54 and arranging and fixing each of them as the orthodox blocks 60 shown in FIG. 6 to the frame, an orthodox unit for awning is formed.
10 and 11 show an example of the formation process of the upright unit 70.

First, as shown in FIG. 10, four vertical leaf bars 73 are arranged and fixed in parallel with each other at predetermined intervals in a quadrangular frame formed by a pair of vertical bars 71 and a pair of horizontal bars 72. The first frame member 74 having the above-mentioned structure is prepared.

Two vertical blocks 60 are placed on each vertical leaf rail 73 of the first frame member 74, and then a screw is inserted into a holed protrusion 55 of the curved circular member 50 at the bottom of each. , Screw to the horizontal rail 72 or the vertical leaf rail 73.

At this time, a common screw is inserted through the holed protrusion 55 of one of the vertical blocks 60 and the holed protrusion 55 of the other vertical block 60, and is screwed into the vertical leaf rail 73.
As a result of the above, as shown in FIG. 11A, a total of eight vertically placed blocks 60 constituting the first stage are fixed to the first frame member 74.

Next, as shown in FIG. 11 (b), the normal block 60 constituting the second stage is placed on the pair of adjacent normal blocks 60.
At this time, the holed protrusion 55 of the lowermost curved circular member 50 of the upper vertical block 60 and the holed protrusion 55 of the uppermost curved circular member 50 of the lower vertical block 60 are aligned. Then, fix each hole with a screw and a nut.

By repeating this work, as shown in FIG. 11 (c), a vertical unit 70 equipped with a total of 13 (1st stage: 8 pieces, 2nd stage: 5 pieces) normal placement blocks 60 is completed. ..
At this time, with respect to each of the vertical blocks 60 constituting the second stage, the protrusion 55 with a hole at the top of the vertical block 60 located in front and the protrusion with a hole at the top of the vertical block 60 located at the rear. 55 and 55 are connected to each other via screws and nuts.

FIG. 12 shows a second frame member 75, in which two horizontal leaf bars 76 are spaced apart from each other in a rectangular frame formed by a pair of vertical bars 71 and a pair of horizontal bars 72. It has a structure in which it is arranged and fixed in parallel with a space.

An inverted block 61 is placed on each of the horizontal leaf bars 76 of the second frame member 75, and a screw is inserted into the protrusion 55 with a hole at the bottom of each to form the horizontal leaf bar 76 or the vertical bar 71. It is fixed by screwing.

At this time, the uppermost holed protrusion 55 of one inverted block 61 and the uppermost holed protrusion 55 of the other adjacent inverted block 61 are connected by screws and nuts.
As a result of the above, as shown in FIG. 13A, a total of eight inverted blocks 61 constituting the first stage are fixed to the second frame member 75.

Next, as shown in FIG. 13B, the inverted block 61 constituting the second stage is placed on the inverted block 61 of the first stage.
At this time, the holed protrusion 55 of the lowermost curved circular member 50 of the upper inverted block 61 and the holed protrusion 55 of the uppermost curved circular member 50 of the lower inverted block 61 are aligned with each other. Insert a screw into each hole and fix it with a nut.
Further, the uppermost holed protrusion 55 of each inverted block 61 constituting the second stage is connected to the uppermost holed protrusion 55 of the other inverted block 61 located laterally via screws and nuts. Will be done.

By repeating this operation, as shown in FIG. 13 (c), an inverted unit 77 equipped with a total of 17 inverted blocks 61 (first stage: 8 pieces, second stage: 9 pieces) is completed.

The vertical unit 70 and the inverted unit 77 are manufactured in the required number in advance at the factory, then transported by truck to the installation site, and assembled as a shade.
FIG. 14 illustrates the completed awning 80, in which the foundation frame 83 is placed on a plurality of legs 82 vertically erected with respect to the installation surface 81, and the vertical unit 70 and the inverted unit 70 are placed on the base frame 83. It depicts the unit 77 being fixed.
The upright unit 70 and the inverted unit 77 are lifted onto the base frame 83 by a forklift or a unic vehicle and fixed by a connector (not shown).

FIG. 15 is a plan view of the awning 80, and shows that the vertical unit 70 and the inverted unit 77 are arranged alternately in the front-rear and left-right directions.
In this way, by arranging the vertical unit 70 having a plurality of vertical blocks 60 and the inverted unit 77 having a plurality of inverted blocks 61 in a so-called checkered pattern, the blocks protruding from one of the units can be formed. It fits into the empty space of the other unit, and it is possible to efficiently form a light-shielding surface with few gaps.

However, the present invention is not limited to such a configuration, and does not exclude the configuration of the awning by using only a large number of awning units of either the normal unit 70 or the inverted unit 77.
In addition, when the awning unit is used to configure the awning in this way, gaps may occur in places on the light-shielding surface. In that case, the gaps can be individually filled by attaching additional awning blocks. Just do it.

In addition, the configuration of each awning unit is not limited to the above, and there are various variations in the number of vertical leaf bars 73 and horizontal leaf bars 76, the mutual spacing, the number of awning blocks to be attached, the mounting method, and the number of stages. Conceivable.

As described above, by directing the long axis of each curved circular member 50 included in each awning block in the east-west direction, the sun's rays are shielded by the convex surface 51 or concave surface 56 of the curved circular member 50, so that the awning effect is obtained. Can be demonstrated. However, the direction of installation is not limited to this.

Moreover, a large number of gaps 57 are formed between each of the curved circular members 50 constituting the awning block or between the basic constituent blocks 52, and the light-shielding surfaces are distributed and arranged in a three-dimensional space. Further, since air convection is generated by the curved surface of each curved circular member 50, heat can be quickly released into the air through the gap 57.

Further, the curved circular member 50 forming the light-shielding surface is based on an "elliptical shape" literally surrounded by a curved line, and the bulging portion overlaps between the ends of the curved circular members 50 arranged above and below. It is equipped (see Fig. 2).
Therefore, as compared with the light-shielding surface of the conventional awning member surrounded by a straight line, it is possible to alleviate the deterioration of the light-shielding performance due to the time and season deviation.

FIG. 16 shows shadows reflected on the ground at the beginning, middle, and end of July in order to confirm the light blocking performance of the conventional awning block having a structure in which the tetrahedron is bent diagonally. Was taken.

Since this conventional awning block is installed at an angle that can block the sunlight as much as possible in early July, as shown in Fig. 16 (a), almost the entire area is shaded in early July. Almost no sunlight leaks.
On the other hand, as shown in Fig. 16 (b), it can be seen that the area of shadows decreased in mid-July, and the area of the sunbeams area γ increased by that amount.
By the end of July, as shown in Fig. 17 (c), it can be seen that the area of the sunbeams region γ has further expanded and the light-shielding region has receded.

On the other hand, FIG. 17 shows the light-shielding performance of sunlight by the awning block formed by using the curved circular member 50, and similarly to the above, on the ground at each south-central time in early, mid-July, and late July. This is a photograph of the reflected shadow.

In this case as well, the sunshade block is installed at an angle that can block the maximum amount of sunlight in early July, but as shown in FIGS. 17 (b) and 17 (c), it is in mid-July and late July. However, it can be confirmed that the high light-shielding performance is maintained with almost no occurrence of the sunbeams region γ.
Incidentally, in this experiment, the following curved circular member 50 was used.
Long axis: 56 mm
Short axis: 37.5 mm
Curved height: 18.8mm

In the above, an example is shown in which the vertical unit 70 and the inverted unit 77 are arranged and fixed horizontally with respect to the installation surface 81, but the vertical unit 70 and the inverted unit 77 can be arbitrarily arranged and fixed with respect to the installation surface 81. It can also be arranged and fixed at an inclination angle.

FIG. 18 shows an example thereof, in which the vertical unit 70 and the inverted unit 77 are placed on a movable plate 84 inclined at a predetermined angle and fixed by screws or the like (not shown).
The tip of the movable plate 84 is rotatably fixed to the base frame 83 via the hinge 85.

A plurality of spacers 86 having a trapezoidal cross section are arranged and fixed between the foundation frame 83 and the movable plate 84.
That is, a first spacer 86a having a relatively low height is placed and fixed at a position close to the hinge 85, and a relatively high third spacer 86c is placed and fixed on the rear end side of the movable plate. There is. Further, a second spacer 86b having a medium height is arranged and fixed in the vicinity of the middle of both spacers.
The upper surface of each spacer 86 is an inclined surface having an angle corresponding to the inclination angle of the movable plate 84.
Due to the presence of these spacers 86, the tilt angle of the movable plate 84 is kept constant, but the number of installations and the installation location are not particularly limited.

The tilt angle of the movable plate 84 can be easily adjusted by replacing each spacer 86 with one having a different height.
That is, although not shown, the tilt angle of the movable plate 84 can be increased by using the first spacer 86a to the third spacer 86c, which are higher than the above.
Alternatively, conversely, the inclination angle of the movable plate 84 can be reduced by replacing the first spacer 86a to the third spacer 86c with ones lower than the above.

By making the tilt angles of the upright unit 70 and the upside-down unit 77 variable in this way, one type of large-scale block 54 (normally placed block 60 and inverted block 61) made of curved circular members 50 having the same configuration can be used. , There is an advantage that it can be applied to various parts of the world with different latitudes.
For example, when installing the awning 80 at a point directly below the equator, the angle of the movable plate 84 is lowered to a state close to horizontal.
On the other hand, when installing the awning 80 in Japan located in the northern hemisphere, the tilt angle of the movable plate 84 is set large.

The tilt angle of the movable plate 84 is not particularly limited, but for example, in the northern hemisphere, the tilt angle can be determined based on the following equation.
■ Tilt angle of movable plate 84 = Latitude of installation location-23.4 degrees (tilt of earth's axis)
The angle obtained by this formula means the tilt angle optimized for the solar solstice at the installation location, but if you want to shift the solar altitude that matches the maximum shielding angle of each awning member after the summer solstice. It can be dealt with by returning it to the horizontal direction by about 8 degrees per month.
However, returning it to the horizontal direction by 20 degrees or more is not preferable because the direct sunlight shielding rate at the summer solstice decreases.

The tilting means of the vertical unit 70 and the inverted unit 77 is not limited to the combination of the above-mentioned "movable plate 84 + hinge 85 + foundation frame 83 + spacer 86".
