fourth dihedrons

11, 12, 14 are on the same plane (front surface). Since the small triangular plate portion 12b forming the side surface of the second dihedron 12 is bent to the bottom side, a triangular small triangular through hole 15 is formed on the front surface of the basic element 2. I have.

triangular plate portions

1a and 1b having a middle triangular through hole 6 at the center are joined via a ridge line R, and a large

triangular plate portion

Therefore, the sunshade member 1 is regarded as a basic element, and four of the sunshade members 1 are arranged right and left, front and rear, and up and down in the same manner as the above

basic elements

2, 3, 4, and 5, so that the sunshade shown in FIG. A shade block which is an assembly of the member 1 is obtained, and a shade having a required size can be obtained by appropriately increasing the number of shade blocks used.

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

By directing the ridge line R of each sunshade member 1 included in the sunshade block to the south side, the sun rays are blocked by the sunshade member 1, so that a sunshade effect can be exhibited.
In addition, a large number of triangular through holes are formed in each sunshade member 1 and the light shielding surfaces are distributed and arranged in a three-dimensional space. Heat can be quickly released into the air.

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

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

In order to achieve the above object, in the awning described in claim 1, a plurality of light-shielding surfaces and a plurality of gaps are three-dimensionally arranged, and when observed from a predetermined light-shielding angle, the respective gaps are arranged behind. A plurality of awning members having a structure that appears to be substantially closed by each light-shielding surface, is a awning provided with a plurality of awning blocks arranged in a certain direction, wherein the awning member is circular or It is formed by using a plurality of curved circular members obtained by curving an elliptical plate material, arranging each curved circular member so that their respective bending directions are aligned, and connecting the mutual ends. Features.

The awning described in claim 2 is the awning according to claim 1, and further includes a plurality of awning units formed by assembling a plurality of the awning blocks to a frame member with their curved concave surfaces aligned in a certain direction, And a support structure for supporting each awning unit at a predetermined height from the ground.

The awning described in claim 3 is the awning according to claim 1, and further includes a plurality of normal units formed by assembling a plurality of the awning blocks to a frame member with their curved concave surfaces aligned in a certain direction. A plurality of inverted units each of which is assembled with the frame material in a state where the sunshade blocks are turned upside down, and a support structure for supporting each of the inverted units and the inverted unit at a predetermined height from the ground, The inverted units are alternately arranged on the support structure.

The awning described in claim 4 is the awning according to

claim

2 or 3, and furthermore, each awning block is placed and fixed between the frame member and the support structure at a predetermined inclination angle with respect to the ground. A tilting means for performing the operation.
As the tilt means, for example, a substrate disposed on the support structure, a movable plate on which the sunshade member unit is mounted and fixed, and the movable plate is rotatably fixed to one end of the substrate. Hinge, and a spacer interposed between the substrate and the movable plate. By changing the height of the spacer, the tilt angle of the unit of the movable plate and the sunshade member can be arbitrarily adjusted. The following 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 curve, and bulges between the ends of the curved circular members arranged vertically. It has a structure where parts overlap.
For this reason, compared with the conventional light-shielding surface of the sunshade member surrounded by a straight line, it is possible to effectively reduce the decrease in light-shielding performance with respect to time and seasonal deviation.

(1) 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 obtained by bending an elliptical plate material around a short axis (short diameter). The convex surfaces 51 of the curved circular members 50 are aligned so as to face the same direction.

As shown in FIG. 1, the long axis ends of a pair of curved circular members 50 are joined together (A), and the short axis ends of a pair of curved circular members 50 are joined together (B). The two curved circular members 50 arranged above are arranged such that both ends of the long axis of each curved circular member 50 are joined to both ends of the short axis of each curved circular member 50 arranged below, that is, four curved circular members The three-dimensional combination of the members 50 is the basic building block 52.

The basic configuration block 52 is a “shade member” that is a minimum unit for configuring the awning.
In FIG. 2, the pair of curved circular members 50 disposed on the lower side is provided with a satin pattern for convenience, thereby distinguishing the pair from the curved circular members 50 disposed on the upper side. In addition, black dots in the figure indicate joining points.

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

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

There is also no particular limitation on the method of joining the curved circular members 50, and bonding, welding, or the like can be selected according to the material.
In the case of a synthetic resin, the basic constituent blocks 52 in which the curved circular members 50 are connected from the beginning can be formed by injection molding.

When the light-shielding surface is formed in an elliptical shape, a range of major axis: minor axis = 2: 1 to 1: 1 (circle) is preferable, and 3: 2 is more preferable.
The sun moves from east to west, so setting the major axis to east-west would increase the light-blocking area of the ground.
If the major axis is too large, the north-south overlap of the light-shielding surfaces decreases, and direct sunlight easily enters when the season changes and the solar altitude changes.

The curved shape of the light-shielding surface preferably has a ratio of the linear length in the major axis direction to the height of the central portion of 2: 1 to 4: 1, more preferably 3: 1.
If the ratio is less than 2: 1, the surface becomes close to a plane, and convection of air is unlikely to occur, so that the temperature rises. If the ratio is larger than 4: 1, when the season is out of the middle of summer and the solar altitude changes, direct sunlight is likely to enter.

By combining the basic building blocks 52 according to a certain rule, a large-scale shade block having a fractal (self-similar shape) structure is formed.
First, as shown in FIG. 4 (a), by combining 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, (C) in which the long axis ends of the curved circular members 50 arranged below the pair of basic constituent blocks 52 are joined together, and above the other pair of curved circular members 50 (D) in which the short-axis end portions arranged at the bottom are joined together, and the long-axis end portions of each curved circular member 50 arranged at the top are shorted to the short ends of the curved circular members 50 arranged at the bottom. What is joined near both ends of the shaft is a medium-sized block 53.

Also, as shown in FIG. 5 (a), by combining four medium-sized blocks 53, as shown in FIG. 5 (b), a large-scale block 54 having 64 curved circular plate members is formed. It is formed.

Specifically, (E) in which the long axis ends of the curved circular members 50 arranged at the lowermost stage of the pair of middle-sized blocks 53 are joined together, and the uppermost stage of the other pair of middle-sized blocks 53 (F) in which the short-axis end portions of the curved circular member 50 arranged in (1) are joined.
Next, both ends of the long axis of the curved circular member 50 arranged at the lowermost stage of each upper middle-sized block 53 are connected to the curved circular members 50 arranged at the uppermost stage of each lower middle-sized block 53. By joining near both ends of the short axis, the large-scale block 54 is completed.

At the long axis end of each of the curved circular members 50 arranged at both ends of the lowermost stage of the large-scale block 54, projections 55 with holes are provided.
Similarly, a projection 55 with a hole is also provided at the short-axis end of each curved circular member 50 disposed at both ends of the uppermost stage of the large-scale block 54.
These projections 55 with holes can be attached after the formation of the large-scale block 54, but it is also possible to use the curved circular member 50 in which the projections 55 with holes are formed at the long axis end or the short axis end in advance. .

6 to 8 show 3D images of the large-scale block 54 (however, the projections 55 with holes are omitted for convenience of illustration).
As shown in FIG. 6, when viewed 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 (the convex surface 51 of the curved circular member 50) is almost completely closed.

On the other hand, as shown in FIG. 7, when the viewpoint is shifted obliquely, it can be seen that many 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 sideways 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 secured. You can see that there is.

In the present invention, the large-scale block 54 may be used in the same orientation as that shown in FIG. 6 or may be used in an inverted state, so the former is referred to as a normal block 60 and the latter is an inverted block. By referring to 61, the two will be distinguished hereinafter.

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

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

First, as shown in FIG. 10, in a rectangular frame formed by a pair of vertical rails 71 and a pair of horizontal rails 72, four vertical leaf rails 73 are arranged and fixed in parallel at a predetermined interval from each other. A first frame member 74 having the above structure is prepared.

After the two normal blocks 60 are placed on each of the vertical leaf bars 73 of the first frame member 74, screws are inserted into the projections 55 with holes of the respective lowermost curved circular members 50. And screw it into the horizontal rail 72 or the vertical leaf rail 73.

At this time, a common screw is inserted into the projection 55 with a hole of one of the normal blocks 60 and the projection 55 with a hole of the other of the normal blocks 60, and screwed into the vertical leaf bar 73.
As a result, as shown in FIG. 11A, a total of eight regular blocks 60 constituting the first stage are fixed to the first frame member 74.

Next, as shown in FIG. 11B, the normal block 60 forming the second stage is placed on a pair of adjacent normal blocks 60.
At this time, the projection 55 with a hole of the lowermost curved circular member 50 of the upper fixed block 60 and the projection 55 with the hole of the uppermost curved circular member 50 of the lower fixed block 60 are aligned. Then, fix each hole with screws and nuts.

By repeating this operation, as shown in FIG. 11 (c), a fixed unit 70 equipped with a total of 13 fixed blocks 60 (first stage: 8, second stage: 5) is completed. .
At this time, with respect to each of the normal blocks 60 forming the second stage, the uppermost holed projection 55 of the frontal block 60 and the uppermost holed protrusion of the rearward block 60 are located. 55 are interconnected via screws and nuts.

FIG. 12 shows a second frame member 75 in which a pair of vertical bars 71 and a pair of horizontal bars 72 form a rectangular frame formed by two horizontal leaf bars 76 at a predetermined distance from each other. Are arranged in parallel and fixed.

The 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 each of the lowermost holed projections 55, so that the horizontal leaf bar 76 or the vertical bar 71 is inserted. 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, 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 projection 55 of the lowermost curved circular member 50 of the upper inverted block 61 and the holed projection 55 of the uppermost curved circular member 50 of the lower inverted block 61 are aligned, Insert screws into each hole and fix with nuts.
Further, the uppermost holed projection 55 of each inverted block 61 constituting the second stage is connected to the uppermost holed projection 55 of the other inverted block 61 located sideways via screws and nuts. Is 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, second stage: 9) is completed.

The required number of the normal unit 70 and the inverted unit 77 are manufactured in advance in a factory, then transported by truck to an installation site, and assembled as a sunshade.
FIG. 14 exemplifies a completed awning 80, in which a base frame 83 is placed on a plurality of legs 82 erected perpendicularly to an installation surface 81, on which a normal unit 70 and an inverted unit The state in which the unit 77 is fixed is illustrated.
The normal unit 70 and the inverted unit 77 are lifted on the base frame 83 by a forklift or a UNIC vehicle, and are fixed by a coupling (not shown).

FIG. 15 is a plan view of the awning 80, and shows a state in which the normal unit 70 and the inverted unit 77 are alternately arranged in the front, rear, left, and right directions.
In this way, by arranging a normal unit 70 including a plurality of normal blocks 60 and an inverted unit 77 including a plurality of inverted blocks 61 in a so-called checkerboard pattern, a block that protrudes from one unit is formed. The shape fits into an empty space in the other unit, and a light-shielding surface with a small gap can be efficiently formed.

However, the present invention is not limited to such a configuration, and does not exclude the configuration of a sunshade by using a large number of sunshade units, either the normal unit 70 or the inverted unit 77.
In addition, when the sunshade is configured using the sunshade unit in this manner, a gap may be formed in some places of the light shielding surface. In such a case, the gap is individually filled by additionally installing a sunshade block. Just fine.

Also, 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, their mutual intervals, or the number and mounting method of sunshade blocks and the number of stages. Conceivable.

As described above, by directing the major axis of each curved circular member 50 included in each awning block in the east-west direction, the sunlight is shielded by the convex surface 51 or the concave surface 56 of the curved circular member 50, so that the shade effect is obtained. Can be exhibited. However, the direction of installation is not limited to this.

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

Furthermore, the curved circular member 50 forming the light-shielding surface is based on an “elliptical shape” literally surrounded by a curve, and a structure in which the bulging portion overlaps between the ends of the curved circular member 50 arranged vertically. (See FIG. 2).
For this reason, compared with the conventional light-shielding surface of the sunshade member surrounded by a straight line, it is possible to alleviate a decrease in light-shielding performance with respect to time or seasonal deviation.

FIG. 16 shows shadows reflected on the ground at each of the southern middle times of early July, middle, and late in order to confirm the solar shading performance of a conventional sunshade block having a structure in which a tetrahedron is bent diagonally. Is taken.

Since this conventional sunshade block is installed at an angle capable of blocking the sunlight in early July as much as possible, as shown in FIG. 16 (a), almost the entire area is shadowed in early July, There is almost no leakage of sunlight.
On the other hand, as shown in FIG. 16 (b), it can be seen that the area of the shadow decreases in the middle of July and the area of the tree leakage day area γ increases accordingly.
At the end of July, as shown in FIG. 17 (c), it can be seen that the area of the tree leakage day area γ further increases, and the light-shielding area recedes.

On the other hand, FIG. 17 shows the light-shielding performance of sunlight by the sunshade block formed using the curved circular member 50. It is a picture of the reflected shadow.

In this case as well, the sunshade block is set at an angle that can block the sunlight in early July as much as possible, but as shown in FIGS. However, it can be confirmed that the tree leakage day region γ hardly occurs and the high light shielding performance is maintained.
Incidentally, the following curved circular member 50 was used in this experiment.
Long axis: 56mm
Short axis: 37.5mm
Curved height: 18.8mm

In the above description, an example is shown in which the normal unit 70 and the inverted unit 77 are arranged and fixed horizontally with respect to the installation surface 81. The arrangement can be fixed at an inclination angle.

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

Between the base frame 83 and the movable plate 84, a plurality of spacers 86 having a trapezoidal cross section are arranged and fixed.
That is, a first spacer 86a having a relatively low height is arranged and fixed at a position close to the hinge 85, and a relatively high third spacer 86c is arranged and fixed at the rear end side of the movable plate. I have. A second spacer 86b having a middle height is arranged and fixed near the middle between the two 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.
Although the inclination angle of the movable plate 84 is kept constant by the presence of these spacers 86, the number and locations of the movable plates 84 are not particularly limited.

The inclination 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 inclination angle of the movable plate 84 can be increased by using first to third spacers 86a to 86c that are higher than those described above.
Alternatively, conversely, by replacing the first spacer 86a to the third spacer 86c with lower spacers, the inclination angle of the movable plate 84 can be reduced.

As described above, by making the inclination angles of the normal unit 70 and the inverted unit 77 variable, one type of large-scale block 54 (the normal block 60 and the inverted block 61) composed of the curved circular member 50 having the same configuration can be used. This has the advantage that it can be used in different parts of the world with different latitudes.
For example, when installing the sunshade 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 sunshade 80 in Japan located in the northern hemisphere, the movable plate 84 is set to have a large inclination angle.

The tilt angle of the movable plate 84 is not particularly limited. For example, in the Northern Hemisphere, the tilt angle can be determined based on the following equation.
■ Inclination angle of movable plate 84 = Latitude of installation location-23.4 degrees (tilt of earth 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 matching the maximum shielding angle of each sunshade member after the summer solstice, It can be dealt with by returning it horizontally about 8 degrees per month.
However, it is not preferable to return the lens to the horizontal direction by 20 degrees or more, since the direct sunlight shielding rate at the summer solstice decreases.

The tilting means of the normal unit 70 and the inverted unit 77 is not limited to the above-described combination of “movable plate 84 + hinge 85 + base frame 83 + spacer 86”.
