Description

本発明は、建築用板と、基材の表面を装飾する模様とに関する。 The present invention relates to building boards and patterns for decorating the surface of a substrate.

建築用板に関する技術が提案されている。例えば、特許文献１は、建築板を開示する。建築板は、外装材である。建築板は、矩形状の凸部を上下左右に複数隣り合うように配置して形成される。凸部は、斜面を有する。斜面は、対向する一対の端部に向かって下り傾斜する。斜面のうちの少なくとも一方には、陰影形成構造が設けられる。陰影形成構造は、突起部である。突起部は、リブ状突起である。リブ状突起は、斜面の傾斜方向に略直交する方向に設けられる。突起部の密度は、凸部の中央部側から端部側に向かって高くなる。突起部の突出高さは、凸部の中央部側から端部側に向かって高くなる。建築板は、十分に立体感を強調することができる。 Technologies related to building boards have been proposed. For example, Patent Document 1 discloses a building board. The building board is an exterior material. The building board is formed by arranging a plurality of rectangular convex portions adjacent to each other vertically and horizontally. The convex portions have slopes. The slopes slope downward toward a pair of opposing ends. At least one of the slopes is provided with a shadow-forming structure. The shadow-forming structure is a protrusion. The protrusion is a rib-shaped protrusion. The rib-shaped protrusion is provided in a direction approximately perpendicular to the inclination direction of the slope. The density of the protrusions increases from the center side of the protrusions toward the ends. The protrusion height increases from the center side of the protrusions toward the ends. The building board can sufficiently emphasize the three-dimensional effect.

特許文献２は、インクジェットプリント物を開示する。インクジェットプリント物は、車両若しくは建築物の内装材又は壁紙である。インクジェットプリント物は、基材と、複数のインクドットとを含む。基材は、吸放湿性を有する。複数のインクドットは、基材の表面に表現された絵柄を形成し、基材の表面の一部領域に形成される。複数のインクドットにより基材の表面に表現された絵柄は、明度が連続的に変化するグラデーションを含む。グラデーションは、Ｌ^＊ａ^＊ｂ^＊表色系における明度Ｌ^＊の最高値と最低値との明度差ΔＬ^＊が８～１２の範囲に設定されている。 Patent Document 2 discloses an inkjet printed matter. The inkjet printed matter is an interior material or wallpaper for a vehicle or building. The inkjet printed matter includes a substrate and a plurality of ink dots. The substrate has moisture absorbing and releasing properties. The plurality of ink dots form a pattern expressed on the surface of the substrate, and are formed in a partial area of the substrate surface. The pattern expressed on the substrate surface by the plurality of ink dots includes a gradation in which the lightness changes continuously. In the gradation, the lightness difference ΔL ^* between the maximum and minimum lightness values L ^* in the L ^* a ^* b ^* color system is set to a range of 8 to 12.

意匠性を有する建築用板が求められている。例えば、建築用板の表面を凹凸状とすることで、表面が平滑な建築用板と比較して表面の立体感を高めることができる。しかしながら、このような建築用板では、これの素材となる板の表面を凹凸状に造形する必要がある。発明者は、建築用板の表面に模様を設け、この模様によって表面に立体感を付与する技術について検討した。 There is a demand for architectural boards with design features. For example, by making the surface of an architectural board uneven, it is possible to enhance the three-dimensional appearance of the surface compared to architectural boards with smooth surfaces. However, in order to produce such architectural boards, it is necessary to mold the surface of the board from which the boards are made to have an uneven appearance. The inventor has investigated a technology for providing a pattern on the surface of an architectural board and using this pattern to give the surface a three-dimensional appearance.

本発明は、立体的な視覚効果を有する建築用板及び模様を提供することを目的とする。 The present invention aims to provide architectural boards and patterns that have a three-dimensional visual effect.

本発明を実施するための実施形態について図面を用いて説明する。本発明は、以下に記載の構成に限定されるものではなく、同一の技術的思想において種々の構成を採用することができる。例えば、以下に示す構成の一部は、省略し又は他の構成に置換してもよい。本発明は、他の構成を含んでもよい。図面は、所定の構成を模式的に示す。 The following describes an embodiment of the present invention with reference to the drawings. The present invention is not limited to the configurations described below, and various configurations can be adopted within the same technical concept. For example, some of the configurations shown below may be omitted or replaced with other configurations. The present invention may include other configurations. The drawings show a schematic representation of a given configuration.

＜建築用板２００＞
建築用板２００について図１～５を参照して説明する。例えば、建築用板２００は、外装材、内装材及び玄関扉用装飾板に使用可能である。外装材の例としては、サイディングが挙げられる。例えば、内装材は、調湿建材、壁材及び室内扉に用いられる。建築用板２００は、基材２１０と、模様２２０とを含む（図１，２参照）。建築用板２００は、模様２２０を含む面を表側として建築物に設けられる。建築用板２００の看者は、建築用板２００が建築物に設置された状態で基材２１０の表面に設けられた模様２２０を視認する。実施形態では、基材２１０の表面は、板状の基材２１０を形成する複数の面のうち、模様２２０が設けられる面を意味する。この場合、基材２１０の表面は、基材２１０の正面（表側面）となり、模様２２０が設けられた状態で建築用板２００の表面（正面，表側面）となる。 <Construction Board 200>
The building board 200 will be described with reference to FIGS. 1 to 5. For example, the building board 200 can be used as an exterior material, an interior material, and a decorative board for an entrance door. An example of an exterior material is siding. For example, the interior material is used for humidity-regulating building materials, wall materials, and interior doors. The building board 200 includes a base material 210 and a pattern 220 (see FIGS. 1 and 2). The building board 200 is installed on a building with the surface including the pattern 220 as the front side. A person viewing the building board 200 visually recognizes the pattern 220 provided on the surface of the base material 210 when the building board 200 is installed on a building. In the embodiment, the surface of the base material 210 means the surface on which the pattern 220 is provided among the multiple surfaces forming the plate-shaped base material 210. In this case, the surface of the base material 210 becomes the front surface (front side surface) of the base material 210, and becomes the surface (front, front side surface) of the building board 200 when the pattern 220 is provided.

基材２１０の例としては、窯業板、金属板、樹脂板、ガラス板及び木板が挙げられる。木板は、木質板を含む。例えば、建築用板２００がサイディングである場合、基材２１０は、窯業板、金属板又は樹脂板であってもよい。但し、基材２１０は、前述とは異なる材質の板材であってもよい。この他、基材２１０は、異なる材質又は同じ材質の板材を含む２層以上の積層板であってもよく、又は２種以上の材質の複合材製の板材であってもよい。基材２１０となる板材の材質は、諸条件を考慮して適宜決定される。例えば、この材質は、建築用板２００の用途又は仕様に応じて適宜決定される。基材２１０の表面は、公知の建築用板の基材と同様、下地処理されてもよい。建築用板２００は、基材２１０として公知の建築用板と同様の基材を採用する。基材２１０の表面が下地処理される場合、公知の下地処理が採用される。従って、基材２１０に関するこの他の説明は省略する。 Examples of the substrate 210 include ceramic boards, metal boards, resin boards, glass boards, and wooden boards. Wooden boards include wood boards. For example, when the building board 200 is siding, the substrate 210 may be a ceramic board, a metal board, or a resin board. However, the substrate 210 may be a board material of a different material than the above. In addition, the substrate 210 may be a laminated board of two or more layers including board materials of different materials or the same material, or may be a board material made of a composite material of two or more materials. The material of the board material to be the substrate 210 is appropriately determined in consideration of various conditions. For example, this material is appropriately determined according to the application or specifications of the building board 200. The surface of the substrate 210 may be primed in the same way as the substrate of a known building board. The building board 200 employs a substrate similar to that of a known building board as the substrate 210. When the surface of the substrate 210 is primed, a known primer treatment is adopted. Therefore, other explanations regarding the substrate 210 are omitted.

模様２２０は、基材２１０の表面を装飾する。基材２１０の表面は、平面形状を有し、模様２２０は、基材２１０の表面に二次元的に形成される（図３参照）。模様２２０の形成方法の例としては、印刷が挙げられる。模様２２０が基材２１０の表面に印刷される場合、模様２２０は、二次元の印刷柄である。印刷の例としては、スクリーン印刷、グラビア印刷及びインクジェット印刷が挙げられる。模様２２０は、基材２１０の表面の全部に設けられる（図１，２参照）。但し、模様２２０が設けられる領域は、基材２１０の表面の一部であってもよい。建築用板２００は、表面に模様２２０を被覆するクリア層を含んでもよい。このクリア層は、模様２２０を保護する。表面にクリア層を設けた建築用板は公知である。従って、クリア層に関するこの他の説明は省略する。 The pattern 220 decorates the surface of the substrate 210. The surface of the substrate 210 has a planar shape, and the pattern 220 is formed two-dimensionally on the surface of the substrate 210 (see FIG. 3). An example of a method for forming the pattern 220 is printing. When the pattern 220 is printed on the surface of the substrate 210, the pattern 220 is a two-dimensional printed pattern. Examples of printing include screen printing, gravure printing, and inkjet printing. The pattern 220 is provided on the entire surface of the substrate 210 (see FIGS. 1 and 2). However, the area on which the pattern 220 is provided may be a part of the surface of the substrate 210. The building board 200 may include a clear layer that covers the pattern 220 on the surface. This clear layer protects the pattern 220. Building boards with a clear layer on the surface are known. Therefore, further explanation of the clear layer is omitted.

模様２２０は、複数の模様部分を含む。模様２２０で任意の１つの模様部分は、１以上の他の模様部分と接する。模様２２０は、複数の模様部分として、模様部分Ａ，Ｂ，Ｃ，Ｄと、模様部分Ｅ，Ｆ，Ｇ，Ｈとを含む（図２，４，５参照）。 Pattern 220 includes multiple pattern portions. Any one pattern portion of pattern 220 is in contact with one or more other pattern portions. Pattern 220 includes multiple pattern portions, including pattern portions A, B, C, and D, and pattern portions E, F, G, and H (see Figures 2, 4, and 5).

模様部分Ａは、模様部分Ｂ，Ｄと接し、模様部分Ｃと向かい合う（図２，４参照）。実施形態では、模様部分Ａ内の領域として、３つの境界領域、別領域及び高明度領域を定義する。３つの境界領域を「境界領域Ａ１，Ａ２，Ａ３」といい、別領域を「別領域Ａ４」といい、高明度領域を「高明度領域Ａ５」という。境界領域Ａ１は、測定位置１０，９，８，７，４２，４１を含み、境界領域Ａ２は、測定位置１１，１３を含み、境界領域Ａ３は、測定位置１０，１１を含む（図４参照）。測定位置については後述する。境界領域Ａ１は、模様部分Ｂと接する。境界領域Ａ２は、模様部分Ｄと接する。境界領域Ａ３は、模様部分Ｃと向かい合う。 Pattern portion A is in contact with pattern portions B and D and faces pattern portion C (see Figs. 2 and 4). In this embodiment, three boundary regions, another region, and a high-brightness region are defined as regions within pattern portion A. The three boundary regions are referred to as "boundary regions A1, A2, and A3," the other region is referred to as "another region A4," and the high-brightness region is referred to as "high-brightness region A5." Boundary region A1 includes measurement positions 10, 9, 8, 7, 42, and 41, boundary region A2 includes measurement positions 11 and 13, and boundary region A3 includes measurement positions 10 and 11 (see Fig. 4).

The multiple pattern portions are each colored differently. The color of the pattern 220 including the multiple pattern portions is specified by the L ^* value, the a ^* value, and the b ^* value in the L ^* a ^* b ^* color system. The L ^* a ^* b ^* color system is a color display method standardized by the International Commission on Illumination (CIE1976) and also specified in JIS (JIS Z 8781-4). The L ^* value is called the lightness index. With regard to the relationship between the L ^* value and the lightness, the higher the lightness, the larger the L ^* value. The difference (lightness difference) between two L ^* values is called the "ΔL ^* value". The ΔL ^* value is the absolute value of the difference between the two L ^* values. The ^a* value and the b ^* value are called the chromaticness index. The a ^* and b ^* values correspond to chromaticity, which indicates hue and saturation. The ^a* value (+) indicates the red direction. The ^a* value (-) indicates the green direction. The ^b* value (+) indicates the yellow direction. The ^b* value (-) indicates the blue direction.

模様部分のａ^＊値及びｂ^＊値は、±５以下であることが好ましい。更に、模様部分のａ^＊値は、±２以下であることがより好ましく、模様部分のｂ^＊値は、±４以下であることがより好ましい。複数の模様部分は、同系色であることが好ましい。この場合、複数の模様部分におけるａ^＊値の範囲は、１０以内であることが好ましく、４以内であることがより好ましい。複数の模様部分におけるｂ^＊値の範囲は、１０以内であることが好ましく、８以内であることがより好ましい。複数の模様部分におけるａ^＊値の範囲は、ａ^＊値が最も大きな模様部分とａ^＊値が最も小さな模様部分とにおけるａ^＊値の差の絶対値を示す。複数の模様部分におけるｂ^＊値の範囲は、ｂ^＊値が最も大きな模様部分とｂ^＊値が最も小さな模様部分とにおけるｂ^＊値の差の絶対値を示す。 The a ^* value and b ^* value of the pattern portion are preferably ±5 or less. Furthermore, the a ^* value of the pattern portion is more preferably ±2 or less, and the b ^* value of the pattern portion is more preferably ±4 or less. The multiple pattern portions are preferably of similar colors. In this case, the range of the a ^* values in the multiple pattern portions is preferably within 10, more preferably within 4. The range of the b ^* values in the multiple pattern portions is preferably within 10, more preferably within 8. The range of the a ^* values in the multiple pattern portions indicates the absolute value of the difference in the a ^{* values between the pattern portion with the largest a*} ^value and the pattern portion with the smallest a ^* value. The range of the b ^* values in the multiple pattern portions indicates the absolute value of the difference in the b ^* values between the pattern portion with the largest b ^* value and the pattern portion with the smallest b ^* value.

In other words, the ΔL ^* value of 24.4 in boundary region F1 where the L ^* value is large is larger than the ΔL ^* value of 9.6 in boundary region E1 where the L ^* value is small.

これに対して、隣接する境界領域Ｇ２，Ｈ１を比較した場合、Ｌ^＊値が小さくなる境界領域Ｈ１のΔＬ^＊値の６．１は、Ｌ^＊値が大きくなる境界領域Ｇ２のΔＬ^＊値の１．２より大きくなる。換言すれば、Ｌ^＊値が大きくなる境界領域Ｇ２のΔＬ^＊値の１．２は、Ｌ^＊値が小さくなる境界領域Ｈ１のΔＬ^＊値の６．１より小さくなる。 In contrast, when comparing the adjacent boundary regions G2 and H1, the ΔL ^* value of 6.1 in the boundary region H1 where the L ^* value is small is greater than the ΔL ^* value of 1.2 in the boundary region G2 where the L ^* value is large.
