  The present invention relates to a repeat arrangement system having a plurality of plate members having a length in a longitudinal direction and a length in a short direction, and a plate member.

Conventionally, a tile unit is known (Patent Document 1).
The tile unit includes a plurality of tiles and a tile connecting unit that integrally connects the plurality of tiles while maintaining a joint gap, and the tile connecting unit exposes a back surface that forms an adhesive surface of the tile. Then, at least the side surface of the tile is detachably gripped without using an adhesive.

However, the tile unit described in Patent Document 1 includes tile connecting means for connecting the plurality of tiles together while maintaining the joint gap, in addition to the plurality of tiles. The arrangement pattern that appears when the unit is constructed is limited, and the design is low.
Furthermore, in the tile unit of Patent Document 1, since the tile connecting means for connecting a plurality of tiles is integrally connected while maintaining the joint gap, the tile connecting means is complicated, and the tile connection according to the arrangement pattern to be constructed is performed. Means are required and manufacturing efficiency is reduced.

  Therefore, the present invention is designed only by manufacturing one type of plate member by setting the repeat length in the longitudinal direction of the unit repeat arrangement portion to (2 × a) times the length in the short direction of the plate member. It is an object of the present invention to provide a repeat arrangement system and a plate member that can simultaneously improve performance, simplify members, and increase manufacturing efficiency.

  The repeat arrangement system 1 according to the present invention is a repeat arrangement system having a plurality of plate members having a length in the longitudinal direction and a length in the short direction, and a ratio a: b of the length in the longitudinal direction and the length in the short direction. A and b in (longitudinal length: short length = a: b) are mutually prime positive integers and a is larger than b (a> b), and one set of two plate members Unit units are formed adjacent to each other, and unit repeat arrangement portions are repeatedly formed by adjoining a plurality of unit units, and this unit repeat arrangement portion is formed by a predetermined plate member in the unit repeat arrangement portion. The repeat length in the longitudinal direction until it appears again at the same position along the longitudinal direction of the predetermined plate member is (2 × a) times (2 × a × short direction length) of the short direction length. ) The first feature that a.

  The second feature of the repeat placement system 1 according to the present invention is that, in addition to the first feature, the unit repeat placement portion is configured such that a predetermined plate member in the unit repeat placement portion is the predetermined repeat member in the unit repeat placement portion. The repeat length in the short direction until it appears again at the same position along the short direction of the plate member is also (2 × a) times (2 × a × short direction length) of the short direction length. There is a point.

  A third feature of the repeat placement system 1 according to the present invention is a repeat placement system having a plurality of plate members having a length in the longitudinal direction and a length in the short direction, the length in the longitudinal direction and the length in the short direction. In the ratio a: b (longitudinal length: short-side length = a: b), a and b are relatively prime positive integers and a is larger than b (a> b), and the plate member A unit unit is formed by adjoining a set of two sheets, and a unit repeat arrangement part is repeatedly formed by adjoining a plurality of the unit units, and the unit repeat arrangement part has a predetermined plate member in the unit repeat arrangement part. In the unit repeat arrangement portion, the longitudinal repeat length until it appears again at the same position along the longitudinal direction of the predetermined plate member is (2 × a) times (2 × a ×) times the lateral length. Short And / or the unit repeat placement portion is located at the same position in the unit repeat placement portion along the short direction of the predetermined plate member in the unit repeat placement portion. The repeat length in the short direction until it appears again is at least (2 × a) times (2 × a × short direction length) the short direction length.

  The fourth feature of the repeat placement system 1 according to the present invention is that, in addition to the first to third features, the plate member is substantially rectangular, and the plate member has a chamfered edge of the plate surface. A chamfered portion is provided, and at least one groove portion formed substantially along the longitudinal direction on the plate surface is provided, and the groove width of the groove portion is approximately twice the chamfer width of the chamfered portion. is there.

  A fifth feature of the repeat placement system 1 according to the present invention is that, in addition to the fourth feature, the groove is formed at a position that equally divides the length in the lateral direction of the plate member. is there.

Due to these characteristics, a and b in the ratio a: b of the longitudinal length L and the lateral length S of the plate member 2 are mutually positive positive integers, and a is larger than b (a> b ), A unit unit 3 in which two plate members 2 are adjacent to each other is formed, a plurality of unit units 3 are adjacent to each other to form a unit repeat arrangement portion 4, and a longitudinal repeat length R of the unit repeat arrangement portion 4 is formed. Unlike the tile unit of Patent Document 1, one type of plate member 2 is manufactured by setting _L to be (2 × a) times (2 × a) times the lateral length S (2 × a × short direction length S). Thus, various arrangement patterns can be made to appear, and the longitudinal repeat length R _L in the unit repeat arrangement portion 4 can be easily determined by the ratio a: b between the longitudinal direction length L and the short direction length S. Adjustable, the length L in the longitudinal direction of the plate member 2 is short Even if the difference in the length in the hand direction S is small (that is, the plate member 2 is not excessively thin), the unit repeat arrangement portion 4 having a sufficient longitudinal repeat length R _L can be formed, and the monotonous repetition However, the repeat arrangement system 1 is rich in design.
Furthermore, unlike the tile unit connecting means of Patent Document 1, the manufacturing efficiency is increased because a separate member corresponding to the arrangement pattern to be constructed is not essential without being complicated.
Therefore, “improvement in design”, “simplification of members”, and “increase in manufacturing efficiency” can be realized at the same time.
In other words, in other words, the repeat arrangement system 1 has the longitudinal repeat length R _{L of} the unit repeat arrangement portion 4 that is (2 × a) times the short direction length S (2 × a × short direction). It can be said that the unit unit 3 is formed by adjoining a pair of two plate members 2 so as to be the length S), and the unit repeat arrangement portion 4 is formed by adjoining a plurality of unit units 3.
In addition, the short direction repeat length R _{S of} the unit repeat arrangement portion 4 may be (2 × a) times the short direction length S (2 × a × short direction length S).
Then, a and b in the ratio a: b of the longitudinal length L and the lateral length S of the plate member 2 are set to prime positive integers and a is larger than b (a> b), and the plate A unit unit 3 in which two members 2 are adjacent to each other is formed, a plurality of unit units 3 are adjacent to each other to form a unit repeat arrangement portion 4, and the unit repeat arrangement portion 4 has a longitudinal repeat length R _L. More than (2 × a) times (2 × a × short direction length S) of the short direction length S and / or the short direction repeat length R _S of the short direction length S ( It may be 2 × a) times (2 × a × short direction length S).

The plate member 2 has a substantially rectangular shape, and includes at least one chamfered portion 11 on the edge of the plate surface 10 and a groove portion 12 substantially along the longitudinal direction on the plate surface 10, and the groove width 12 W of the groove portion 12 is chamfered. By setting the chamfering width 11W of the portion 11 to be approximately twice the minimum chamfering width 11W, a plurality of minimum units of the handle (flat portions of the plate surface 10 (portions other than the chamfered portion 11 and the groove portion 12)) are provided in one plate member 2. It can be formed, and naturally the size of the plate member 2 itself is larger than the minimum unit of the handle. Improves.
In addition to this, since the plate member 2 is larger than the minimum unit of the handle, it is difficult to be affected by the foundation to be constructed (unevenness such as unevenness).
At the same time as these features, the groove portion 12 may be formed at a position where the lateral length S of the plate member 2 is substantially equally divided.

  The plate member 2 according to the present invention is a plate member having a length in the longitudinal direction and a length in the short direction, and the ratio of the length in the longitudinal direction to the length in the short direction a: b (length in the longitudinal direction: short). In the direction length = a: b), a and b are relatively prime positive integers, a is larger than b (a> b), and a is not a positive integer multiple of b (a ≠ n × b , N is a positive integer).

  The second feature of the plate member 2 according to the present invention is that, in addition to the first feature, the plate member is substantially rectangular, and the plate member is a chamfered portion having a chamfered edge of the plate surface. And at least one groove portion formed substantially along the longitudinal direction on the surface of the plate, and the groove width of the groove portion is approximately twice the chamfer width of the chamfered portion.

  A third feature of the plate member 2 according to the present invention is that, in addition to the first feature, the groove is formed at a position that equally divides the length of the plate member in the lateral direction. .

Due to these characteristics, a and b in the ratio a: b of the longitudinal length L and the lateral length S of the plate member 2 are mutually positive positive integers, and a is larger than b (a> b ) A is not a positive integer multiple of b (a ≠ n × b, where n is a positive integer), even if the difference between the length L in the plate member 2 and the length S in the short direction is small. In particular, since a ≠ n × b, even if the plate member 2 is not excessively thin, the predetermined plate member 2 is identical to the adjacent plate member 2 among the plurality of applied plate members. The plate member 2 can be constructed and arranged so that the length until it reappears at the relative position becomes a sufficient length, does not repeat monotonously, and is rich in design.
Further, unlike the tile unit connecting means of Patent Document 1, it is not complicated and a separate member corresponding to the arrangement pattern to be constructed is not essential, so that the manufacturing efficiency is increased.
By this, it can be said that “improvement in design”, “simplification of members”, and “increase in production efficiency” can be realized simultaneously.

The plate member 2 has a substantially rectangular shape, and includes at least one chamfered portion 11 on the edge of the plate surface 10 and a groove portion 12 substantially along the longitudinal direction on the plate surface 10, and the groove width 12 W of the groove portion 12 is chamfered. By setting the chamfering width 11W of the portion 11 to be approximately twice the minimum chamfering width 11W, a plurality of minimum units of the handle (flat portions of the plate surface 10 (portions other than the chamfered portion 11 and the groove portion 12)) are provided in one plate member 2. It can be formed, and naturally the size of the plate member 2 itself is larger than the minimum unit of the handle. Improves.
In addition to this, since the plate member 2 is larger than the minimum unit of the handle, it is difficult to be affected by the foundation to be constructed (unevenness such as unevenness).
At the same time as these features, the groove portion 12 may be formed at a position where the lateral length S of the plate member 2 is substantially equally divided.

  According to the repeat arrangement system according to the present invention, by making the repeat length of the unit repeat arrangement portion to be (2 × a) times the short direction length of the plate member, etc., only one type of plate member is manufactured. "Improvement of design", "Simplification of members", and "Increase in production efficiency" can be realized at the same time.

The chamfered portion 11 is formed by obliquely cutting the edge of the plate surface 10, but the angle of the chamfered portion 11 with respect to the plate surface 10 is not particularly limited, for example, 30 ° or more and 60 °. In the following, it may be preferably 35 ° or more and 55 °, more preferably 40 ° or more and 50 ° (approximately 45 ° or the like).
Further, the depth of the chamfered portion 11 (width of the chamfered portion 11 in the side view of the plate member 2) is not particularly limited, but when the angle of the chamfered portion 11 with respect to the plate surface 10 is approximately 45 °. Is substantially the same value as the chamfer width 11W, for example, 0.1 mm or more and 10.0 mm or less, preferably 0.3 mm or more and 5.0 mm, more preferably 0.6 mm or more and 2.0 mm (1.0 mm or the like). It may be.
The chamfered portion 11 may be formed by cutting obliquely, or may be formed by pressing, and the means thereof is not limited. Further, the chamfered portion 11 may be colored later, or it may be cut at an angle to expose the underlying hue. Furthermore, the chamfered portion 11 may be subjected to protective coating or the like.

<Groove part 12, groove width 12W>
As shown in FIGS. 1 to 24 (particularly, FIGS. 2 and 3), the plate member 2 includes at least one groove portion 12 formed substantially along the longitudinal direction L ′ with respect to the plate surface 10. Yes.
In addition, when the planar view shape of the plate member 2 is a substantially rectangular shape, the groove part 12 will be formed substantially along two long sides in the plate member 2, and the length of the groove part 12 is the long side length. The length may be substantially the same as the length L, or may be shorter than the long side length L.

Further, even when the planar shape of the plate member 2 is other than a substantially rectangular shape (a shape in which irregularities are provided on each side of a substantially rectangular shape, a substantially parallelogram, etc.), the groove portion 12 is in contact with the plate surface 10. In this case, the length of the groove 12 may be substantially the same as the length L in the longitudinal direction or shorter than the length L in the longitudinal direction. It doesn't matter.
The groove width 12 (width of the groove 12 in plan view of the plate member 2) 12W is not particularly limited, but is, for example, 0.2 mm or more and 20.0 mm or less, preferably 0.6 mm or more and 10.0 mm, and more preferably. May be 1.2 mm or more and 4.0 mm (2.0 mm or the like).

The groove portion 12 is formed by providing a concave portion that is continuous with the plate surface 10, but the depth of the groove portion 12 of such a concave portion (that is, the groove portion 12) is not particularly limited as with the chamfered portion 11. For example, it may be 0.1 mm or more and 10.0 mm or less, preferably 0.3 mm or more and 5.0 mm, more preferably 0.6 mm or more and 2.0 mm (1.0 mm or the like).
Further, the cross-sectional shape of the groove portion 12 is not particularly limited, and may be, for example, a substantially V shape, a laterally substantially U shape, a substantially semicircular shape, a substantially semielliptical shape, or the like.

Hereinafter, the cross-sectional shape of the groove part 12 will be described in detail mainly when it is substantially V-shaped. The substantially V-shaped groove part 12 has the most concave center in the groove width direction, and from the groove edge of the groove part 12, It is formed by cutting obliquely toward the most concave portion in the approximate center.
The angle of the cut substantially V-shaped groove 12 with respect to the plate surface 10 is not particularly limited, and is, for example, 30 ° to 60 °, preferably 35 ° to 55 °, and more preferably 40 ° to 50 ° (approximately 45). ° etc.).
The groove part 12 may be cut and formed in the same manner as the chamfered part 11, or may be formed by pressing, and the means thereof is not limited. Further, the groove 12 may be colored later, or may be cut obliquely to expose the underlying hue. Further, protective coating or the like may be applied to the groove 12.

With the plate member 2 described so far, it is possible to form a plurality of minimum handle units (portions surrounded by the chamfered portion 11 and the groove portion 12 on the plate surface 10) in one plate member 2, and naturally the size of the plate member 2 itself. Since the length becomes larger than the minimum unit of the handle, the workability is improved as much as the plate member 2 can be put together as compared with the case where the member divided for each minimum unit of the handle is applied.
In addition to this, since the plate member 2 is larger than the minimum unit of the handle, it is difficult to be affected by the foundation to be constructed (unevenness such as unevenness).

The groove width 12W of the groove portion 12 may be approximately twice the chamfering width 11W of the chamfered portion 11, and when the chamfered portions 11 of the adjacent plate members 2 are combined, the combined 2 The width of one chamfered portion 11 (two chamfered widths 12W) is substantially the same as the groove width 12W of the grooved portion 12.
In particular, as described later, if the cross-sectional shape of the groove portion 12 is substantially V-shaped, it is difficult to distinguish between the chamfered portion 11 and the groove portion 12 that are joined together, and the joint between the adjacent plate members 2 is difficult to distinguish. Becomes inconspicuous.

Moreover, the groove part 12 may be formed in the position which divides | segments the short side length (short-side direction length) S in the plate member 2 substantially equally, for example, one plate member 2 is provided with the two groove parts 12. FIG. In this case, these groove portions 12 are formed at positions that divide the short side length S into approximately three parts (the minimum unit of the handle in the plate member 2 is three).
Similarly, when one plate member 2 includes three groove portions 12, these groove portions 12 are formed at positions that divide the short side length S into approximately four equal parts and include four groove portions 12. In this case, these groove portions 12 are formed at positions that divide the short side length S into approximately five equal parts.
The plate member 2 described so far can be said to be common in the repeat arrangement system 1 of the first embodiment and the second embodiment.

<Unit unit 3>
As shown in FIGS. 1, 4 to 24, the unit unit 3 is formed by adjoining the plate member 2 described above as a set (on a surface such as a floor surface).
At this time, the two plate members 2 constituting the unit unit 3 have at least the same shape in plan view, and in addition, the thickness t of the plate member 2 may be the same.

The unit unit 3 may be formed such that the two plate members 2 are adjacent to each other so that the respective longitudinal directions L ′ intersect, or adjacent to each other so that the respective longitudinal directions L ′ are substantially parallel. .
First, the case where the longitudinal directions L ′ of the two plate members 2 intersect will be described.

When the unit unit 3 intersects the longitudinal direction L ′ of the two plate members 2, the intersecting angle is substantially the same as the angle at which the longitudinal direction L ′ and the short direction S ′ of the plate member 2 intersect. The same.
As long as the longitudinal direction L ′ of the two plate members 2 intersects, the unit unit 2 is not particularly limited in the positional relationship between the two plate members 2 that intersect, but for example, the overall shape of the unit unit 2 The (planar shape) may be L-shaped, substantially L-shaped, substantially T-shaped, T-shaped, or the like.

If the entire shape of the unit unit 3 is described in detail, first, the L-shaped unit unit 3 (3A) is placed at the end position of one long side of one plate member 2 and one of the other plate members 2 The short sides are adjacent (contact), the short side of one plate member 2 (the end on the side where the other plate member 2 is adjacent), and the long side of the other plate member 2 (L-shaped) The long side on the outside is substantially straight (see FIGS. 1, 4 to 24).
In addition, it can be said that Examples 1-1 to 1-11 shown in FIGS. 1 and 4 to 13 have the L-shaped unit unit 3A, and at the same time, a stepped type (later longitudinal direction L). It can be said that it has the unit unit 3 ('is substantially parallel) (reference numeral 3E in FIGS. 1, 4 to 13).

On the other hand, although it can be said that Examples 2-6 to 2-12 shown in FIGS. 19 to 24 have the L-shaped unit unit 3 (3A), at the same time, the substantially L-shaped unit described later, It can also be said that it has a substantially T-shaped and T-shaped unit unit 3 (reference numerals 3B, 3C, and 3D in FIGS. 19 to 24).
Then, the substantially L-shaped unit unit 3 (3B) will be described in detail next. The substantially L-shaped unit unit 3B is located at the end position of one long side of the one plate member 2 on the other plate member 2. The point where one short side is adjacent (contacted) is the same as the L-shape, but the short side of one plate member 2 (the end on the side where the other plate member 2 is adjacent) is The other side of the plate member 2 is different from the long side (the long side outside the L-shape) in that it is not substantially straight (reference numeral 3B in FIGS. 19, 22, and 24). 6, 2-9, 2-11)).

The substantially L-shaped unit unit 3B refers to a unit in which the short side of one plate member 2 is not substantially aligned with the long side of the other plate member 2 (that is, shifted). The other plate member 2 is slightly displaced to the inside of the substantially L shape (see FIGS. 19 and 22), or is slightly displaced to the outside of the substantially L shape (see FIG. 24). Any of these may be used.
Note that the other plate member 2 is displaced outward in a substantially L-shape (substantially L-shaped unit unit 3B) is displaced outward within a range in which the adjacent state of the two plate members 2 can be secured.

Next, the substantially T-shaped unit unit 3 (3C) will be described in detail. The substantially T-shaped unit unit 3C has a substantially central position of one long side of one plate member 2 (a position excluding an accurate central position). ), One short side of the other plate member 2 is adjacent (contacted) (reference numeral 3C in FIGS. 19 and 21 (Examples 2-6 and 2-8)).
The unit unit 3 shown in FIG. 19 is substantially T-shaped, but as described above, it can be said that it is a substantially L-shaped unit unit 3B shifted inward.

The T-shaped unit unit 3 (3D) will be described in detail. The T-shaped unit unit 3D is located at the center of one long side of one plate member 2 at one short side of the other plate member 2. The sides are adjacent (contact) (reference numeral 3D in FIG. 20 (Example 2-7)).
In the case of this T-shaped unit unit 3D, in one long side of one plate member 2, there is a portion where the short side of the other plate member 2 is not adjacent, but the non-adjacent portion is There are two places across the other plate member 2, and the lengths of the two non-adjacent portions are the same.

Finally, the stepped unit unit 3E (3E) formed adjacently so that the longitudinal direction L ′ of the two plate members 2 is substantially parallel will be described in detail. One long side of the other plate member 2 is adjacent to (in contact with) one long side of the other plate member 2 (reference numeral 3E in FIGS. 1, 4 to 13 (Examples 1-1 to 1-1). -11)).
As shown in FIGS. 1 and 4 to 13, the length in which the long sides of the two plate members 2 are adjacent to each other is the length in the longitudinal direction of the plate member 2 (long side length) L-short. The direction length (short side length) S (that is, LS) is obtained.

As described so far, the unit unit 3 uses two plate members 2 having the same planar view shape depending on how the two plate members 2 are adjacent to each other, adjacent positions, and adjacent lengths (adjacent lengths). Even if it exists, it turns out that it forms in a wide variety of whole shapes, such as L shape, a substantially L shape, a substantially T shape, a T shape, and a step type.
As described above, the unit repeat arrangement unit 4 described below is required to appropriately arrange the unit units 3 from various unit units 3 according to the length in the longitudinal direction: the length in the short direction = a: b. longitudinal repeat length R _L is not a (2 × a) times (2 × a × short direction length S) of the short-side direction length S.

<Unit Repeat Arrangement Unit 4>
As shown in FIGS. 1 and 4 to 24, the unit repeat placement unit 4 is formed by adjoining a plurality of the above unit units 3, and this unit repeat placement unit 4 is repeated (repeat) in the repeat placement system 1. Has been placed.
At this time, the plurality of unit units 3 forming the unit repeat arrangement unit 4 are repeatedly arranged adjacent to each other in the same direction so that the mutual positional relationship is the same.

  As shown in the above-described embodiments (Examples 1-1 to 1-11, 2-1 to 2-11), the unit repeat arrangement unit 4 is configured so that the unit unit 3 (plate member 2) is separated by a gap (or another The second embodiment in which the arrangement unit 4 of the first embodiment arranged without laying out without M and the unit unit 3 (plate member 2) is laid out with a gap (or another member) M between them. The arrangement section 4 is roughly divided.

As shown in FIGS. 1 and 4 to 13, in the unit repeat arrangement unit 4 in the first embodiment, the unit unit 3 that forms the arrangement unit 4 is the above-described step type unit unit 3E (L It can be said that it is a character-type unit 3A).
In the unit repeat arrangement portion 4 of the first embodiment, the side of the plate member 2 in the arrangement portion 4 (if the planar view shape of the plate member 2 is a substantially rectangular shape, the long side and the short side are the plate member 2. If the shape of the plan view of 2 is not substantially rectangular, all of the surrounding sides (peripheries)) must be any of the other plate members 2 arranged around the plate member 2. Adjacent to crab.

14-24, the unit repeat arrangement | positioning part 4 in 2nd Embodiment is unit unit 3B which forms this arrangement | positioning part 4, The substantially L-shaped unit unit 3B mentioned above, The substantially T-shaped unit unit 3B. The unit unit 3C is a T-shaped unit unit 3D (this embodiment can also be said to be an L-shaped unit unit 3A).
In the unit repeat arrangement part 4 of the second embodiment, since there is a gap (or another member) M, the side of the plate member 2 in the arrangement part 4 (long side and short side of the substantially rectangular plate member 2) Or a portion of the periphery of the plate member 2 other than the substantially rectangular shape (periphery) that is not adjacent to any of the plurality of other plate members 2 arranged around the plate member 2 ing.

<Repeat length R>
As shown in FIGS. 1, 4 to 24, the repeat length R is the length until the predetermined plate member 2 in the unit repeat arrangement portion 4 appears again at the same position in the unit repeat arrangement portion 4. It is.
Specifically, there are two repeat lengths R: a longitudinal repeat length R _L and a short repeat length R _S , which will be described in detail below.

<Longitudinal repeat length R _L >
As shown in FIGS. 1, 4 to 24, the longitudinal repeat length R _L is a predetermined plate member 2 in the unit repeat arrangement portion 4 (for example, the plate member 2 at the upper left in the unit repeat arrangement portion 4 ( 1, 4 to 24) is a length until the unit repeat arrangement portion 4 appears again at the same position along the longitudinal direction L ′ of the predetermined plate member 2.
This longitudinal repeat length R _L is expressed by the following common formula 1 shown below regardless of whether the first embodiment or the second embodiment described above.

Here, c and d in the above formula 1 will be described.
First, c represents one unit unit 3 among adjacent unit units 3 along the longitudinal direction L ′ of a predetermined plate member 2 (for example, the plate member 2A described above) in the unit repeat arrangement portion 4. The length (M _L ) of the gap (or another member) M formed when the position is shifted is set to a ratio of the length _L in the longitudinal direction to the length S in the short direction a: b: c (length L in the longitudinal direction: This is the ratio value c in the short direction length S: the length M _L in the longitudinal direction M = a: b: c) (see symbol c in FIGS. 1 and 4 to 24). The gap (or another member) M formed when the unit unit 3 is displaced along the longitudinal direction L ′ of the predetermined plate member 2 has a length in the longitudinal direction _ML, but the length in the short direction is the plate. It becomes the length L in the longitudinal direction of the member 2 itself.

On the other hand, d indicates that one of the adjacent unit units 3 is placed in the short direction S ′ of the predetermined plate member 2 (for example, the plate member 2A described above) in the unit repeat arrangement portion 4. the lateral direction length M _S of the gap (or another member) M capable when shifted along, the ratio a between the longitudinal length L and a lateral direction length S: b: d (longitudinal length L: Short direction length S: Ratio value d in the short direction length M _S = a: b: d) of the gap M (see symbol d in FIGS. 1 and 4 to 24). Note that the gap (or another member) M formed when the unit unit 3 is shifted along the short direction S ′ of the predetermined plate member 2 has a short length M _S, but the long length is The length (LS) is obtained by subtracting the length in the lateral direction from the length L in the longitudinal direction of the plate member 2.
That is, the length in the longitudinal direction L: the length in the short direction S: the length in the longitudinal direction M _{L of the} gap M: the length in the short direction M _{S of the} gap M = a: b: c: d, and the values of c and d May not be a positive integer as long as a and b are relatively prime positive integers, and c> 0 and d = 0, c = 0 and d> 0, or , C = 0 and d = 0.
Note that, depending on the values of a, b, c, and d described above, Equation 1 can be expressed as R _L = m × {L × x + S × y} (where m is a positive integer, x and y are positive, 0 In other words, the longitudinal repeat length R _L in this case is L × x + S × y (R _L = L × x + S × y) divided by m. In addition to the above three cases, the values of c and d may be c> 0 and d> 0, but only the arrangement in which the unit units 3 can be repeatedly adjacent to each other is indicated.

Thus, the longitudinal repeat length R _L is determined by the values of a, b, c, and d, but a and b are mutually prime positive integers, and a is larger than b (a> b), c By setting = 0 and d = 0, the longitudinal repeat length R _L can be expressed by (product of the longitudinal length L and b) and (short) from R _L = L (b + 0) + S (a + 0-0) (The product of the direction lengths S and a) (R _L = L × b + S × a).
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b is L × b = S × a, the longitudinal repeat length R _L is R _L = L × b + S × a = S × a + S × a (= 2 × S × a = 2 × a × S) or R _L = L × b + S × a = L × b + L × b (= 2 × L × b = 2 × b × L) It can be said that there is.
Hereinafter, description will be made mainly assuming that R _L = 2 × a × S.

As described above, when R _L = 2 × a × S, as in Examples 1-1 to 1-11 described later, only one type of plate member 2 is manufactured. Plate arrangement member, the longitudinal repeat length _RL in the unit repeat placement portion 4 can be easily adjusted by the ratio a: b between the longitudinal length L and the transverse length S, and the plate member 2 is a unit repeat arrangement having a sufficient longitudinal repeat length R _L even if the difference between the longitudinal length L and the lateral length S in FIG. 2 is small (ie, the plate member 2 is not excessively thin). The part 4 can be formed, and the repeat arrangement system 1 is rich in design without being monotonous.
At the same time, by setting R _L = 2 × a × S, the unit repeat arrangement unit 4 (that is, the repeat arrangement system 1) allows the unit unit 3 (plate member 2) to have a gap (or another member) M. It becomes 1st Embodiment arrange | positioned without laying down, and since the means etc. which connect the plate member 2 are unnecessary, it does not become complicated, and since the separate member according to the arrangement pattern to construct is not essential, manufacturing efficiency rises. .
Therefore, “improvement in design”, “simplification of members”, and “increase in manufacturing efficiency” can be realized at the same time.
In other words, in other words, the repeat arrangement system 1 has the longitudinal repeat length R _{L of} the unit repeat arrangement portion 4 that is (2 × a) times the short direction length S (2 × a × short direction). It can be said that the unit unit 3 is formed by adjoining a pair of two plate members 2 so as to be the length S), and the unit repeat arrangement portion 4 is formed by adjoining a plurality of unit units 3.

The specific length of the longitudinal repeat length _RL is, for example, a longitudinal length (long side length) L of 457.2 mm and a short side length (short side length) S of 304.8 mm ( L = 457.2 mm, S = 304.8 mm), and when c = 0 and d = 0, the longitudinal length L: the transverse length S: the longitudinal length M _{L of the} gap M: the gap M The length in the short direction M _S = a: b: c: d = 3: 2: 0: 0. In this case, since R _L = 2 × a × S, the longitudinal repeat length R _L is short. From (2 × 3) times the side length S304.8 mm, (2 × 3 × 304.8 mm =) 1828.8 mm.
That is, it turns out that the longitudinal repeat length R _L in the unit repeat arrangement portion 4 is close to 2 m by using the rectangular plate member 2 of 457.2 mm × 304.8 mm.

Further, by making a and b a relatively positive integer and a being larger than b (a> b), and c ≧ 0 and d = 0, or c = 0 and d ≧ 0, the longitudinal direction The repeat length R _L can be set to (2 × a) times or more (R _L ≧ 2 × a × S) of the short direction length S, and has a sufficient longitudinal repeat length R _L. The unit repeat arrangement part 4 can also be formed, and the repeat arrangement system 1 does not have a monotonous repetition and is rich in design.
In particular, when R _L > 2 × a × S, the unit repeat arrangement unit 4 (that is, the repeat arrangement system 1) has a gap (or another member) between each unit unit 3 (plate member 2). ) It becomes 2nd Embodiment of the repeat arrangement | positioning system 1 arrange | positioned by laying down, having M, It is also possible to arrange | position each unit unit 3 (plate member 2) with the clearance gap M, and it is another member which fills the clearance gap M, for example Even if it is used, it is sufficient if there is one kind of separate member corresponding to the shape of the gap M, so that it is not excessively complicated, and it can be said that the manufacturing efficiency is increased.

<Repeat length R _S in the short direction>
As shown in FIGS. 1, 4 to 24, the short direction repeat length R _S is determined by the predetermined plate member 2 (for example, the plate member 2 </ b> A described above) in the unit repeat arrangement portion 4. 4, the length until the plate member 2 appears again at the same position along the short direction S ′ of the predetermined plate member 2.
This short direction repeat length R _S is also expressed by the following common formula 2 shown below regardless of whether the first embodiment or the second embodiment described above.

Here, c and d in the formula 2 are the same as c and d described in the formula 1.
Further, depending on the values of a, b, c, and d described so far, Equation 2 can also be expressed as R _S = m ′ × {S × x ′ + L × y ′} (where m ′ is a positive integer, x ′ , Y ′ may be expressed in the form of a positive, 0, or negative integer), and the short direction repeat length R _{S in} this case is also S × x ′ + L × y ′ (divided by m ′. R _S = S × x ′ + L × y ′).

Thus, the short direction repeat length R _S is also determined by the values of a, b, c, and d, and a and b are mutually prime positive integers and a is larger than b (a> b), By setting c = 0 and d = 0, the short direction repeat length R _S can be expressed as (product of the short direction length S and a) from R _S = S (a + 0-0) + L (b + 0) (The product of the longitudinal lengths L and b) (R _S = S × a + L × b).
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b is L × b = S × a, the repeat length R _S in the short direction is also R _S = S × a + L × b = It can be said that 2 × a × S = 2 × b × L.
Hereinafter, description will be made mainly assuming that R _S = 2 × a × S.

Thus, even if R _S = 2 × a × S, as in Examples 1-1 to 1-11 described later, only one type of plate member 2 is manufactured, and the short direction S ′ is The repeat arrangement system 1 is rich in design.
Further, even if R _S = 2 × a × S, the unit repeat arrangement unit 4 (that is, the repeat arrangement system 1) spreads the unit unit 3 (plate member 2) without a gap (or another member) M. It can be said that the first embodiment is arranged and the complication of the members is suppressed, and the manufacturing efficiency is increased.
Therefore, “improvement in design”, “simplification of members”, and “increase in manufacturing efficiency” can be realized at the same time.
The plate member 2 is arranged such that the short direction repeat length R _{S of} the unit repeat arrangement portion 4 is (2 × a) times the short direction length S (2 × a × short direction length S). It can also be said that the unit repeater 4 is formed by adjoining a pair of two units to form a unit unit 3 and adjoining a plurality of unit units 3.

The specific length of the short direction repeat length R _S is, for example, L = 457.2 mm, S = 304.8 mm, and c = 0 and d = 0, the long direction length L: the short direction length S: Longitudinal length M _{L of the} gap M _L : Length of the gap M in the short direction M _S = a: b: c: d = 3: 2: 0: 0 In this case, R _S = 2 × From a × S, the short direction repeat length R _S is also 2 × 3 × 304.8 mm = 1828.8 mm.
That is, it can be seen that by using the rectangular plate member 2 of 457.2 mm × 304.8 mm, the short direction repeat length R _S in the unit repeat arrangement portion 4 is also close to 2 m.

Also, by making a and b a relatively positive integer and a greater than b (a> b), and c ≧ 0 and d = 0, or c = 0 and d ≧ 0, The direction repeat length R _S can also be greater than or equal to (2 × a) times the short direction length S (R _S ≧ 2 × a × S), and the repeat arrangement system 1 is rich in design.
In particular, when R _S > 2 × a × S, the unit repeat arrangement unit 4 (that is, the repeat arrangement system 1) has a gap (or another member) between the unit units 3 (plate members 2). ) It becomes 2nd Embodiment of the repeat arrangement | positioning system 1 arrange | positioned by laying down, having M, Even if another member which fills the clearance gap M is used, it is enough if there is one kind of separate member according to the shape of the clearance gap M Therefore, it can be said that the manufacturing efficiency is increased because it is not excessively complicated.

<Example 1-1 (a: b = 3: 2 (= 1.5: 1.0))>
As shown in FIGS. 1 to 3, in the repeat arrangement system 1 of Example 1-1, the planar view shape of the plate member 2 is substantially rectangular, and the length L in the longitudinal direction: the length S in the short direction: Length M _L in the longitudinal direction of the gap M: Length M _S in the short direction of the gap M = a: b: c: d = 3: 2: 0: 0 (= 1.5: 1.0: 0.0: 0.0).
That is, in Example 1-1, the repeat arrangement system 1 according to the first embodiment in which the unit units 3 (plate members 2) are spread and arranged without gaps (or other members) M from c = 0 and d = 0. And it can be said that the unit unit 3 is an L-shaped unit unit 3A (or a stepped unit unit 3E).

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d as described above, the repeat length R in the longitudinal direction of the unit repeat arrangement portion 4 of Example 1-1. _L is 6 × S (6 times the length in the short side direction (short side length) S), which is expressed by the above equation 1 with a = 3, b = 2, c = 0, d = 0. Is the same value as R _L = 2 × 3 × S = 6 × S calculated by substituting.

<Summary of Examples 1-1 to 1-11>
Table 1 below summarizes the longitudinal repeat length R _L and the short repeat length R _S of Examples 1-1 to 1-11 described so far.
The order of publication in Table 1 is not the order of the numbers in the examples, but the length (long side length) L in the longitudinal direction is the order in which the ratio (magnification) of the length in the short direction (short side length) S is small. It is posted.

As shown in Table 1, the plate member 2 (unit unit 3) is set to a value of prime positive integers a and b and c = 0 and d = 0 in the respective examples 1-1 to 1-11. As a matter of fact, in any of the embodiments, the unit repeat arrangement unit 4 always has a square shape with one side (2 × a) times the short side length S (R _L = R _S = 2 × a × S).
Therefore, by substituting the values of relatively prime positive integers a and b other than the examples 1-1 to 1-11 listed here and c = 0 and d = 0 into equations 1 and 2, unit repeat It can be said that the longitudinal direction repeat length R _L and the short direction repeat length R _S of the arrangement part 4 can be derived.

In particular, in Examples 1-5 and 1-7, although the ratio is shifted by 0.2 from Example 1-6 in which a is twice b, the longitudinal repeat length R _L and the short length The direction repeat length R _S extends up to about 5 times.
Further, even when Examples 1-5 and 1-7 are longer than Examples 1-9 and 1-10, where a is 3 or 5 times as long as b, the longitudinal repeat length R _L and The short direction repeat length R _S is about double.
Therefore, when the plate member 2 in which a is not a positive integer multiple of b is used, even if the difference between the length L in the longitudinal direction and the length S in the short direction is small, the unit repeat arrangement portion 4 is not monotonously repeated. It can be said that the repeat arrangement system 1 is rich in design.

<Example 2-1 (a: b = 9: 5 (= 1.8: 1.0), c = 1)
As shown in FIG. 14, in the repeat arrangement system 1 of Example 2-1, the planar view shape of the plate member 2 is a substantially rectangular shape, and the length L in the longitudinal direction: the length S in the short direction: the gap M Length in the longitudinal direction M _L : length in the transverse direction M _S = a: b: c: d = 9: 5: 1: 0 (= 1.8: 1.0: 0.2: 0. 0).
That is, Example 2-1 is a second embodiment in which c> 0 and d = 0, and the two unit units 3 (plate members 2) are laid and arranged with a gap (or another member) M between the unit units 3 (plate members 2). In the repeat arrangement system 1, the unit unit 3 can be said to be an L-shaped unit unit 3 </ b> A (or a unit unit 3 </ b> E having a different level).

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the longitudinal repeat length R _L of Example 2-1 is 19.8 × S. has a (widthwise direction 19.8 times the length S), which, in the formula 1 a = 9, b = 5 , c = 1, by substituting d = 0 is calculated R _L = L × (5 + 0) + S × {9+ (9/5) −0} = L × 5 + S × 9 + S × (9/5), longitudinal length L: lateral length S = a: b Since b = S × a, R _L = 2 × 9 × S + (9/5) × S = {18+ (9/5)} × S = 19.8 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-1 is 6.6 × S (6.6 times the short direction length S).
On the other hand, R _s = S × (9 + 0−0) + L × {5 + 1} = S × 9 + L × 6 = calculated by substituting a = 9, b = 5, c = 1, and d = 0 into Equation 2 above. 3 × (S × 3 + L × 2).
This R _S = 3 × (S × 3 + L × 2) is the above-described R _S = m ′ × {S × x ′ + L × y ′}, where m ′ = 3, x ′ = 3, and y ′ = 2. In this case, the short direction repeat length R _S is R _S = S × 3 + L × 2 divided by 3.
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b, L = S × (a / b) = S × (9/5), R _S = S × 3 + S × ( 9/5) × 2 = {3+ (9/5) × 2} × S = {3+ (18/5)} × S = (33/5) × S = 6.6 × S. This is the same value as the short direction repeat length R _S 6.6 × S in Example 2-1.

That is, in Example 2-1, the longitudinal repeat length R _L of 19.8 × S is three times shorter than the short direction repeat length R _S 6.6 × S, and the unit repeat arrangement unit 4 Is a rectangular shape (in other words, a horizontally long rectangular shape) whose longitudinal direction L ′ is three times longer than the short direction S ′ of the predetermined plate member.
Note that this value of “3” times is the same as the value of m ′ = “3”, which was divided last when the short direction repeat length R _S was calculated by the above equation 2.

This is calculated by substituting a = 9, b = 5, c = 2, and d = 0 into Equation 1 above, R _L = L × (5 + 0) + S × {9+ (18/5) ) −0} = L × 5 + S × 9 + S × (18/5), since the length in the longitudinal direction L: the length in the short direction S = a: b, L × b = S × a, so that R _L = It is the same value as 2 × 9 × S + (18/5) × S = {18+ (18/5)} × S = 21.6 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of the embodiment 2-2 is also found. 21.6 × S.
On the other hand, R _s = S × (9 + 0−0) + L × {5 + 2} = S × 9 + L × 7 calculated by substituting a = 9, b = 5, c = 2, and d = 0 into Equation 2 above. Since the length in the longitudinal direction L: the length in the short direction S = a: b is L = S × (a / b), R _L = S × 9 + S × (9/5) × 7 = {9+ ( 63/5)} × S = 21.6 × S, which is the same value as the repeat length R _S 21.6 × S in the short direction of Example 2-2 when actually arranged.
That is, in Example 2-2, the unit repeat arrangement unit 4 has a square shape (R _L = R _S = 21.6 × S) having one side that is 21.6 times the short side length S.

<Example 2-3 (a: b = 9: 5 (= 1.8: 1.0), c = 3>
As shown in FIG. 16, in the repeat arrangement system 1 of Example 2-3, the plate member 2 has a substantially rectangular shape in plan view, and has a longitudinal length L: a lateral length S: a gap M. Length M _L : length in the short direction M _S = a: b: c: d = 9: 5: 3: 0 (= 1.8: 1.0: 0.6: 0. 0).
That is, Example 2-3 is also the second embodiment in which c> 0 and d = 0, so that each unit unit 3 (plate member 2) is laid and arranged with a gap (or another member) M between them. In the repeat arrangement system 1, the unit unit 3 can be said to be L-shaped or uneven unit units 3 </ b> A and 3 </ b> E.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the longitudinal repeat length R _L of Example 2-3 is 23.4 × S. This is calculated by substituting a = 9, b = 5, c = 3, and d = 0 into the above equation 1, R _L = L × (5 + 0) + S × {9+ (27/5) ) −0} = L × 5 + S × 9 + S × (27/5), L × b = S × a from the length in the longitudinal direction L: the length in the short direction S = a: b, so that R _L = It is the same value as 2 × 9 × S + (27/5) × S = {18+ (27/5)} × S = 23.4 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-3 is also found. 23.4 × S.
On the other hand, R _s = S × (9 + 0−0) + L × {5 + 3} = S × 9 + L × 8 calculated by substituting a = 9, b = 5, c = 3, and d = 0 into the above equation 2. Since the length in the longitudinal direction L: the length in the short direction S = a: b is L = S × (a / b), R _L = S × 9 + S × (9/5) × 8 = {9+ ( 72/5)} × S = 23.4 × S, which is the same value as the short direction repeat length R _S 23.4 × S of Example 2-3 when actually arranged.
That is, also in Example 2-3, the unit repeat arrangement unit 4 has a square shape (R _L = R _S = 23.4 × S) having one side that is 23.4 times the short side length S.

<Example 2-4 (a: b = 9: 5 (= 1.8: 1.0), c = 4)
As shown in FIG. 17, in the repeat arrangement system 1 of Example 2-4, the planar view shape of the plate member 2 is substantially rectangular, and the longitudinal direction length L: the lateral direction length S: the gap M Length in the longitudinal direction M _L : length in the short direction M _S = a: b: c: d = 9: 5: 4: 0 (= 1.8: 1.0: 0.8: 0. 0).
In Example 2-4, the length M _L in the longitudinal direction of the gap M is equal to the difference obtained by subtracting the length S in the short direction from the length _L in the longitudinal direction (c = a−b).
Further, in Example 2-4, since c> 0 and d = 0, the unit unit 3 (plate member 2) is laid and arranged with a gap (or another member) M between the unit units 3 (plate members 2). It can be said that the unit unit 3 of the repeat arrangement system 1 is an L-shaped unit unit 3A.

When the plate member 2 (unit unit 3) is actually arranged with the values a, b, c, and d described above, the longitudinal repeat length R _L of Example 2-4 is 25.2 × S. This is calculated by substituting a = 9, b = 5, c = 4, and d = 0 into Equation 1 above. R _L = L × (5 + 0) + S × {9+ (36/5) ) −0} = L × 5 + S × 9 + S × (36/5), L × b = S × a from the length L in the longitudinal direction and the length in the short direction S = a: b, so that R _L = It is the same value as 2 × 9 × S + (36/5) × S = {18+ (36/5)} × S = 25.2 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-3 is It is very small and is 2.8 × S.
On the other hand, R _s = S × (9 + 0−0) + L × {5 + 4} = S × 9 + L × 9 = calculated by substituting a = 9, b = 5, c = 4, and d = 0 into the above formula 2. 9 × (S × 1 + L × 1).
This R _S = 9 × (S × 1 + L × 1) is the above-mentioned R _S = m ′ × {S × x ′ + L × y ′}, where m ′ = 9, x ′ = 1, and y ′ = 1. The short direction repeat length R _S is R _S = S × 1 + L × 1 divided by 9.
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b, L = S × (a / b) = S × (9/5), R _S = S × 1 + S × ( 9/5) × 1 = {1+ (9/5)} × S = (14/5) × S = 2.8 × S, and the repeat length in the short direction of Example 2-4 when actually arranged R _S is the same value as 2.8 × S.

That is, in Example 2-4, 25.2 × S of the longitudinal repeat length R _L is 9 times the short-direction repeat length R _S 2.8 × S, and the unit repeat arrangement unit 4 Is a rectangular shape (in other words, a very horizontally long rectangular shape) whose longitudinal direction L ′ is 9 times longer than the short direction S ′ of the predetermined plate member.
Note that the value of “9” times is the same as the value of m ′ = “9”, which is finally divided when the short direction repeat length R _S is calculated by the above equation 2.

<Example 2-5 (a: b = 9: 5 (= 1.8: 1.0), c = 5)
As shown in FIG. 18, in the repeat arrangement system 1 of Example 2-5, the planar view shape of the plate member 2 is substantially rectangular, and the length L in the longitudinal direction: the length S in the short direction: the gap M Length in the longitudinal direction M _L : length in the short direction M _S = a: b: c: d = 9: 5: 5: 0 (= 1.8: 1.0: 1.0: 0. 0).
In Example 2-5, the length M _L in the longitudinal direction of the gap M is larger than the difference obtained by subtracting the length S in the short direction from the length _L in the longitudinal direction (c> ab).
Further, in Example 2-5, since c> 0 and d = 0, each unit unit 3 (plate member 2) is laid and arranged with a gap (or another member) M between the unit units 3 (plate member 2). It can be said that the unit unit 3 of the repeat arrangement system 1 is an L-shaped unit unit 3A.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c and d described above, the longitudinal repeat length R _L of Example 2-5 is 27.0 × S. This is calculated by substituting a = 9, b = 5, c = 5, and d = 0 into Equation 1 above. R _L = L × (5 + 0) + S × {9+ (45/5) ) −0} = L × 5 + S × 9 + S × 9, since the length L in the longitudinal direction: the length in the short direction S = a: b, L × b = S × a, so that R _L = 3 × 9 × It is the same value as S = 27.0 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the short direction repeat length R _{S of} Example 2-5 is also found. 27.0 × S.
On the other hand, R _s = S × (9 + 0−0) + L × {5 + 5} = S × 9 + L × 10 calculated by substituting a = 9, b = 5, c = 5, and d = 0 into Equation 2 above. Since the length in the longitudinal direction L: the length in the short direction S = a: b is L = S × (a / b), R _L = S × 9 + S × (9/5) × 10 = {9+ ( 90/5)} × S = 27.0 × S, which is the same value as the repeat length R _S 27.0 × S in Example 2-5 when actually arranged.
That is, also in Example 2-5, the unit repeat arrangement unit 4 has a square shape (R _L = R _S = 27.0 × S) having one side that is 27.0 times the short side length S.

<Example 2-6 (a: b = 9: 5 (= 1.8: 1.0), d = 1)>
As shown in FIG. 19, in the repeat arrangement system 1 of Example 2-6, the planar view shape of the plate member 2 is substantially rectangular, but is different from the previous Examples 2-1 to 2-5. Longitudinal length L: Short direction length S: Longitudinal length M _{L of} gap M: Short direction length M _{S of} gap M = a: b: c: d = 9: 5: 0: 1 (= 1.8: 1.0: 0.0: 0.2).
That is, Example 2-6 is the second embodiment in which c = 0 and d> 0, and the two unit units 3 (plate members 2) are laid and arranged with a gap (or another member) M between the unit units 3 (plate members 2). It is a repeat arrangement system 1 and its unit unit 3 is an L-shaped unit unit 3A (or a substantially L-shaped unit unit 3B, a substantially T-shaped unit unit 3C, or a stepped unit unit 3E). It can be said that.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the longitudinal repeat length R _L of Example 2-6 is 9.4 × S. This is calculated by substituting a = 9, b = 5, c = 0, and d = 1 into Equation 1 above. R _L = L × (5 + 1) + S × {9 + 0−1} = L × 6 + S × 8 = 2 × (L × 3 + S × 4).
This R _L = 2 × (L × 3 + S × 4) is the case where m = 2, x = 3, and y = 4 in the above-described R _L = m × {L × x + S × y}. The repeat length R _L is R _L = L × 3 + S × 4 divided by 2.
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b, L = S × (a / b) = S × (9/5), so that R _L = S × (9 / 5) × 3 + S × 4 = {(27/5) +4} × S = (47/5) × S = 9.4 × S, and the repeat length in the longitudinal direction of Example 2-6 when actually arranged It is the same value as R _L 9.4 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-6 is 18.8 × S.
On the other hand, R _s = S × {9+ (9/5) −1} + L × (5 + 0) = S calculated by substituting a = 9, b = 5, c = 0, and d = 1 into Equation 2 above. Since X {8+ (9/5)} + L × 5 and L × b = S × a from the length in the longitudinal direction L: the length in the short direction S = a: b, R _L = S × {8+ (9/5)} + S × 9 = {17+ (9/5)} × S = 18.8 × S, and the repeat length R _{S in} the short direction of Example 2-6 when actually arranged is 18. The value is the same as 8 × S.

That is, in Example 2-6, the short direction repeat length R _S 18.8 × S is twice the long direction repeat length R _L 9.4 × S, and the unit repeat arrangement unit 4 is The rectangular direction (that is, a vertically long rectangular shape) in the short direction S ′ is twice as long as the longitudinal direction L ′ of the predetermined plate member.
Note that the value of “2” times is the same as the value of m = “2” divided last when the longitudinal repeat length R _L is calculated by the above equation 1.

<Example 2-7 (a: b = 9: 5 (= 1.8: 1.0), d = 2)>
As illustrated in FIG. 20, in the repeat arrangement system 1 of Example 2-7, the planar view shape of the plate member 2 is a substantially rectangular shape, and the longitudinal length L: the short direction length S: the gap M Length in the longitudinal direction M _L : Length in the transverse direction M _S = a: b: c: d = 9: 5: 0: 2 (= 1.8: 1.0: 0.0: 0.4 ).
That is, Example 2-7 is the second embodiment in which c = 0 and d> 0, and the two unit units 3 (plate members 2) are laid and arranged with a gap (or another member) M between the unit units 3 (plate members 2). In the repeat arrangement system 1, the length M _S in the short direction of the gap M is equal to one half of (the difference obtained by subtracting the length S in the short direction from the length L in the long direction) {d = (a -B) / 2}, it can be said that the unit 3 is an L-shaped, T-shaped, or uneven unit unit 3A, 3D, 3E.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c and d described above, the longitudinal repeat length _RL of Example 2-7 is very small. It is 8xS.
This is calculated by substituting a = 9, b = 5, c = 0, and d = 2 into Equation 1 above. R _L = L × (5 + 2) + S × {9 + 0-2} = L × 7 + S × 7 = 7 × (L × 1 + S × 1).
This R _L = 7 × (L × 1 + S × 1) is a case where, in the above-described R _L = m × {L × x + S × y}, m = 7, x = 1, y = 1, and the longitudinal direction The repeat length R _L is R _L = L × 1 + S × 1 divided by 7.
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b, L = S × (a / b) = S × (9/5), so that R _L = S × (9 / 5) × 1 + S × 1 = {(9/5) +1} × S = (14/5) × S = 2.8 × S, and the repeat length in the longitudinal direction of Example 2-7 when actually arranged R _L is the same value as 2.8 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-7 is 19.6 × S.
On the other hand, R _s = S × {9+ (18/5) −2} + L × (5 + 0) = S calculated by substituting a = 9, b = 5, c = 0, and d = 2 into Equation 2 above. Since X {7+ (18/5)} + L × 5, L × b = S × a from the length in the longitudinal direction L: the length in the short direction S = a: b, R _L = S × {7+ (18/5)} + S × 9 = {16+ (18/5)} × S = 19.6 × S, and the repeat length R _{S in} the short direction of Example 2-7 when actually arranged is 19. The value is the same as 6 × S.

That is, in Example 2-7, the short direction repeat length R _S 19.6 × S is seven times the long direction repeat length R _L 2.8 × S, and the unit repeat arrangement unit 4 is The rectangular direction S ′ is 7 times longer than the longitudinal direction L ′ of the predetermined plate member (in other words, a very vertically long rectangular shape).
Note that this value of “7” times is the same as the value of m = “7”, which is divided last when the longitudinal repeat length R _L is calculated by the above equation 1.

<Example 2-8 (a: b = 9: 5 (= 1.8: 1.0), d = 3)
As shown in FIG. 21, in the repeat arrangement system 1 of Example 2-8, the planar view shape of the plate member 2 is a substantially rectangular shape, and the longitudinal length L: the short direction length S: the gap M Longitudinal length M _L : Short direction length M _{S of} gap M = a: b: c: d = 9: 5: 0: 3 (= 1.8: 1.0: 0.0: 0.6 ).
That is, Example 2-8 is the second embodiment in which c = 0 and d> 0, and the two unit units 3 (plate members 2) are laid and arranged with a gap (or another member) M between the unit units 3 (plate members 2). In the repeat arrangement system 1, the unit 3 can be said to be an L-shaped, a substantially L-shaped, a substantially T-shaped or a stepped unit unit 3A, 3B, 3C, 3E.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the longitudinal repeat length R _L of Example 2-8 is 10.2 × S. It has become.
This is calculated by substituting a = 9, b = 5, c = 0, d = 3 into Equation 1 above, R _L = L × (5 + 3) + S × {9 + 0-3} = L × 8 + S × 6 = 2 × (L × 4 + S × 3).
This R _L = 2 × (L × 4 + S × 3) is the case where, in the above-mentioned R _L = m × {L × x + S × y}, m = 2, x = 4, and y = 3, and the longitudinal direction The repeat length R _L is R _L = L × 4 + S × 3 divided by 2.
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b, L = S × (a / b) = S × (9/5), so that R _L = S × (9 / 5) × 4 + S × 3 = {(36/5) +3} × S = (51/5) × S = 10.2 × S, and the repeat length in the longitudinal direction of Example 2-8 when actually arranged It is the same value as R _L 10.2 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-8 is 20.4 × S.
On the other hand, R _s = S × {9+ (27/5) −3} + L × (5 + 0) = S calculated by substituting a = 9, b = 5, c = 0, and d = 3 into Equation 2 above. Since X {6+ (27/5)} + L × 5 and L × b = S × a from the length in the longitudinal direction L: the length in the short direction S = a: b, R _L = S × {6+ (27/5)} + S × 9 = {15+ (27/5)} × S = 20.4 × S, and the repeat length R _{S in} the short direction of Example 2-8 when actually arranged 20. The value is the same as 4 × S.

That is, in Example 2-8, the short direction repeat length R _S 20.4 × S is twice the long direction repeat length R _L 10.4 × S, and the unit repeat arrangement unit 4 is The rectangular direction (that is, a vertically long rectangular shape) in the short direction S ′ is twice as long as the longitudinal direction L ′ of the predetermined plate member.
Note that the value of “2” times is the same as the value of m = “2” divided last when the longitudinal repeat length R _L is calculated by the above equation 1.

<Example 2-9 (a: b = 9: 5 (= 1.8: 1.0), d = 8)
As shown in FIG. 22, in the repeat arrangement system 1 of Example 2-9, the plate member 2 has a substantially rectangular shape in plan view, and has a longitudinal length L: a lateral length S: a gap M. Length M _L : length in the short direction M _S = a: b: c: d = 9: 5: 0: 8 (= 1.8: 1.0: 0.0: 1. 6).
That is, Example 2-9 is also the second embodiment in which c> 0 and d = 0, so that each unit unit 3 (plate member 2) is laid and arranged with a gap (or another member) M between them. In the repeat arrangement system 1, the unit unit 3 can be said to be L-shaped, substantially L-shaped or uneven unit units 3 </ b> A, 3 </ b> B, 3 </ b> E.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the longitudinal repeat length R _L of Example 2-9 is 24.4 × S. This is calculated by substituting a = 9, b = 5, c = 0, and d = 8 into Equation 1 above. R _L = L × (5 + 8) + S × {9 + 0−8} = L × 13 + S × longitudinal length 1 L: short direction length S = a: since b is from L = S × (a / b ), R L = S × (9/5) × 13 + S × 1 = {(117/5) +1} × S = 24.4 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c and d described above, the repeat length R _{S in} the short direction of Example 2-9 is also found. 24.4 × S.
On the other hand, R _s = S × (9+ (72/5) −8) + L × {5 + 0} = S calculated by substituting a = 9, b = 5, c = 0, and d = 8 into Equation 2 above. Since X {1+ (72/5)} + L × 5, the length in the longitudinal direction L: the length in the short direction S = a: b, and L × b = S × a, R _L = S × {1+ (72/5)} + S × 9 = {10+ (72/5)} × S = 24.4 × S, and the repeat length R _{S in} the short direction of Example 2-9 when actually arranged 24. The value is the same as 4 × S.
That is, in Example 2-9, the unit repeat arrangement unit 4 has a square shape (R _L = R _S = 24.4 × S) having one side that is 24.4 times the short side length S.

<Example 2-10 (a: b = 9: 5 (= 1.8: 1.0), d = 9)>
As shown in FIG. 23, in the repeat arrangement system 1 of Example 2-10, the planar view shape of the plate member 2 is a substantially rectangular shape, and the longitudinal length L: the short direction length S: the gap M Length in the longitudinal direction M _L : Length in the transverse direction M _S = a: b: c: d = 9: 5: 0: 9 (= 1.8: 1.0: 0.0: 1.8 ).
In Example 2-10, the length M _S in the short direction of the gap M is equal to the length L in the long direction (d = a).
Further, in Example 2-10, since c = 0 and d> 0, each unit unit 3 (plate member 2) is laid and arranged with a gap (or another member) M between the unit units 3 (plate member 2). It can be said that the unit unit 3 of the repeat arrangement system 1 is an L-shaped unit unit 3A.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c and d described above, the longitudinal repeat length R _L of Example 2-10 is very small. It is 8xS.
This is calculated by substituting a = 9, b = 5, c = 0, and d = 9 into Equation 1 above. R _L = L × (5 + 9) + S × {9 + 0-9} = L × 14 + S × 0 = 14 × L + S × 0.
This R _L = 14 × L + S × 0 is a case where m = 14, x = 14, and y = 0 in the above-described R _L = m × {L × x + S × y}, and the longitudinal repeat length R _L is R _L = L divided by 14.
Here, since the length in the longitudinal direction L: the length in the short direction S = a: b, L = S × (a / b) = S × (9/5), so that R _L = L = (9 / 5) × S, which is the same value as the longitudinal repeat length R _L 1.8 × S of Example 2-10 when actually arranged.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-8 is 25.2 × S.
On the other hand, R _s = S × {9+ (81/5) −9} + L × (5 + 0) = S calculated by substituting a = 9, b = 5, c = 0, and d = 9 into Equation 2 above. Since X (81/5) + L × 5, the length in the longitudinal direction L: the length in the short direction S = a: b, and L × b = S × a, R _L = S × {9+ (81 / 5)} = (126/5) × S = 25.2 × S, which is the same value as the repeat length R _S 25.2 × S in the short direction of Example 2-10 when actually arranged. Yes.

That is, in Example 2-10, the short direction repeat length R _S 25.2 × S is 14 times the long direction repeat length R _L 1.8 × S, and the unit repeat arrangement unit 4 is The rectangular direction S ′ is 14 times longer than the longitudinal direction L ′ of the predetermined plate member (in other words, a very vertically long rectangular shape).
The value multiplied by “14” is the same as the value of m = “14”, which is finally divided when the longitudinal repeat length R _L is calculated by the above equation 1.

<Example 2-11 (a: b = 9: 5 (= 1.8: 1.0), d = 10)

In Example 2-11, the length M _S in the short direction of the gap M is larger than the length L in the long direction (d> a).
Further, in Example 2-11, since c> 0 and d = 0, each unit unit 3 (plate member 2) is laid and arranged with a gap (or another member) M between the unit units 3 (plate members 2). In the repeat arrangement system 1, the unit unit 3 can be said to be L-shaped or uneven unit units 3 </ b> A and 3 </ b> E.

When the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the longitudinal repeat length R _L of Example 2-11 is 26.0 × S. This is calculated by substituting a = 9, b = 5, c = 0, and d = 10 into Equation 1 above. R _L = L × (5 + 10) + S × {9 + 0-10} = L × 15−S × 1 Longitudinal length L: Short direction length S = a: From b = L = S × (a / b), R _L = S × (9/5) × It is the same value as 15−S × 1 = (27−1) × S = 26.0 × S.

Similarly, when the plate member 2 (unit unit 3) is actually arranged with the values of a, b, c, and d described above, the repeat length R _{S in} the short direction of Example 2-11 is also found. 26.0 × S.
On the other hand, R _s = S × (9+ (90/5) −10) + L × {5 + 0} = S calculated by substituting a = 9, b = 5, c = 0, and d = 8 into Equation 2 above. Since X (18-1) + L × 5, the length in the longitudinal direction L: the length in the short direction S = a: b, and L × b = S × a, R _L = S × (17 + 9) + S × 9 = 26.0 × S, which is the same value as the repeat length R _S 26.0 × S in the short direction of Example 2-11 when actually arranged.
That is, in Example 2-11, the unit repeat arrangement unit 4 has a square shape (R _L = R _S = 26.0 × S) having one side as long as 26.0 times the short side length S.

<Summary of Examples 2-1 to 2-11>
Table 2 below summarizes the lengthwise repeat length R _L and the widthwise repeat length R _S of Examples 2-1 to 2-11 described so far.
In addition, the order of publication in Table 2 is the order of numbers in the examples.

As shown in Table 2, among Examples 2-1 to 2-11, Examples 2-1 to 2-5 where c> 0 and d = 0 are the lengths M _L in the longitudinal direction of the gap M. Each time the value of the ratio c increases by 1, the longitudinal repeat length _RL increases by 1.8. This 1.8 is the ratio of the plate member 2 (the length in the short direction of the length L in the longitudinal direction). It can be said that it is equal to the ratio to S).
On the other hand, in Examples 2-6 to 2-11 in which c = 0 and d> 0, each time the value d of the ratio d of the short direction length M _S of the gap M increases by 1, the short direction repeat length R _S. Can be said to be equal to a value obtained by subtracting a ratio value 1.0 corresponding to the length S in the lateral direction from the ratio 1.8 of the plate member 2.

In Examples 2-1, 2-4, 2-6 to 2-8, and 2-10, the unit repeat arrangement portion 4 has a rectangular shape. -4 is a horizontally long rectangular shape whose longitudinal repeat length _RL is a positive integer multiple of the short repeat length _RS , and Examples 2-6 to 2-8 and 2-10 are The short direction repeat length R _S is a vertically long rectangular shape that is a positive integer multiple of the long direction repeat length R _L.
The repeat arrangement system 1 having such a rectangular unit repeat arrangement portion 4 has a plate member 2 having the same ratio as the length L in the longitudinal direction: the length S in the short direction S = 9: 5 in the first to fifth embodiments. The gap (or another member) M is opened by slightly changing the ratio value c of the length M _L in the longitudinal direction of the gap M and the value d of the ratio of the length M _{S in} the short direction. For example, the longitudinal repeat length R _L and the short repeat length R _{S of} the unit repeat arrangement portion 4 are the same as the longitudinal repeat length R _L (2 × a × S) of Example 1-5. It can be said that the repeat arrangement system 1 is larger and has more design.
On the other hand, the other short direction repeat length R _S and the long direction repeat length R _L of the rectangular unit repeat arrangement portion 4 are smaller than 2 × a × S.
Therefore, in the repeat placement system 1 having the rectangular unit repeat placement portion 4, at least one of the longitudinal repeat length R _L and the short repeat length R _S is 2 × a × S or more (longitudinal direction). It can be said that the repeat length R _L is 2 × a × S) or more and / or the short direction repeat length R _S is 2 × a × S or more).

And in the other Examples (Examples 2-2, 2-3, 2-5, 2-9, 2-11), the longitudinal repeat length R _{L of} the unit repeat placement portion 4 is the short direction repeat. It is equal to the length R _S (R _L = R _S ) and has a square shape with one side.
The repeat arrangement system 1 having such a square unit repeat arrangement section 4 has a plate member 2 having the same ratio as the length L in the longitudinal direction and the length S in the short direction in the embodiment 1-5 described above. The gap (or another member) M is opened by slightly changing the ratio value c of the length M _L in the longitudinal direction of the gap M and the value d of the ratio of the length M _{S in} the short direction. Only the longitudinal repeat length R _L and the short repeat length R _S of the unit repeat arrangement portion 4 are larger than the longitudinal repeat length R _{L of} Example 1-5. Thus, it can be said that the repeat arrangement system 1 is richer in design.
Therefore, in the repeat arrangement system 1 having the square unit repeat arrangement section 4, both the longitudinal repeat length R _L and the short repeat length R _S are 2 × a × S or more (longitudinal repeat length). The length R _L is 2 × a × S) and / or the short direction repeat length R _S is 2 × a × S).
