Description
本発明は、化粧シートに関するものであり、特には、車や家屋等の室内装飾、基材，機器，物品の表面装飾等に適した化粧シートに関するものである。 The present invention relates to a decorative sheet, and more particularly, to a decorative sheet suitable for interior decoration of a car, a house, etc., a surface decoration of a base material, equipment, or article.
化粧シートは、基材，機器，物品の外観的付加価値を高めるために広く使用されており、特に、乗用車の車内装飾ではインパネやシートの高級感を高める目的等で各種の化粧シートが用いられている。 Decorative sheets are widely used to increase the added value of the appearance of substrates, equipment, and articles. Various decorative sheets are used for the interior decoration of passenger cars and for the purpose of enhancing the sense of quality of instrument panels and sheets. ing.
この化粧シートとしては、凹凸面によるコントラストの違いによって絵柄を表すものが一般に知られているが、更に付加価値を高めるために、視認する方向によって異なる絵柄が視認できるものが提案されている。 As this decorative sheet, a sheet representing a pattern due to a difference in contrast due to the uneven surface is generally known, but in order to further increase the added value, a sheet capable of visually recognizing a different pattern depending on the viewing direction has been proposed.
下記特許文献１には、表面に形成された複数の平行線状凸部と複数の平行線状凹部と、複数の平行線状凸部のうちの所定の凸部の第１側に突出して形成された第１画素部と、複数の平行線状凸部のうちの所定の凸部の第１側に突出して形成された第２画素部とを備え、第１画素部が集まって第１画像を形成し、第２画素部が集まって第２画像を形成し、第１画素部の表面は線状凸部から第１側に向かって下がる第１角度傾斜面を有し、第２画素部の表面は線状凸部から第２側に向かって下がる第２角度傾斜面を有するエンボス版が記載されている。
前述した従来技術を採用してエンボス加工した化粧シートを形成すると、第１側から斜視した場合には第１の絵柄を見ることができ、第２側から斜視した場合には第２の絵柄を見ることができる。しかしながら、表面を正面から見た場合には、第１の絵柄と第２の絵柄が合成された画像が見えることになり、化粧シートに適用した場合に、最も頻繁に視認される正面視で意図する絵柄を視認できないという問題がある。 When the decorative sheet embossed with the above-described conventional technology is formed, the first pattern can be seen when viewed from the first side, and the second pattern when viewed from the second side. Can see. However, when the surface is viewed from the front, an image in which the first pattern and the second pattern are synthesized can be seen, and when applied to a decorative sheet, it is the most frequently viewed front view. There is a problem that the pattern to be viewed is not visible.
これに対して、表面に照射される光を散乱する梨地面の表面と表面に照射される光を特定方向に反射する表面を形成して、その梨地面の表面部分と反射面の表面部分とのコントラスト差によって絵柄を形成することで、正面視の場合にも所定の絵柄を得ることが可能になる。 On the other hand, the surface of the pear ground that scatters the light applied to the surface and the surface that reflects the light applied to the surface in a specific direction are formed. By forming the pattern based on the difference in contrast, it is possible to obtain a predetermined pattern even when viewed from the front.
しかしながら、この梨地面の表面部分を単に前述した従来技術に適用して、正面視の場合も含めてユニークな複数の絵柄が得られるように構成することを考えた場合には、斜視の場合に梨地面の表面部分が暗く見えてしまい、斜視の場合に視認できる絵柄に正面視の場合に視認できる絵柄が合成された状態になり、やはり、意図する絵柄を視認できないという問題が生じる。 However, in the case of strabismus, it is considered that the surface portion of the pear ground is simply applied to the above-described conventional technology so as to obtain a plurality of unique patterns including a front view. The surface portion of the pear ground looks dark, and the pattern that can be seen in front view is combined with the pattern that can be seen in perspective, and the intended pattern cannot be seen again.
そして、前述したように合成された絵柄が視認される場合には、一つの絵柄から急に他の絵柄に変わる場合に得られる意外性が失われることになり、異なる絵柄を切り換えるという付加価値が十分に発揮できない問題が生じる。 When the synthesized pattern is visually recognized as described above, the unexpectedness obtained when one pattern is suddenly changed to another pattern is lost, and the added value of switching between different patterns is lost. There is a problem that cannot be fully demonstrated.
本発明は、このような問題に対処することを課題とするものである。すなわち、表面を正面視する場合を含めて、視認方向に応じて異なる絵柄を視認できるようにすること、正面視の場合に視認できる絵柄と斜視の場合に視認できる絵柄がそれぞれ合成されること無く視認できること、一つの絵柄から視認方向を変えるだけで急に他の絵柄に切り変わるようにすることで、高い意外性が得られ、異なる絵柄を切り換えるという付加価値を十分に発揮できること、等が本発明の目的である。 An object of the present invention is to deal with such a problem. In other words, including the case where the surface is viewed from the front, it is possible to visually recognize different patterns depending on the viewing direction, and the design that can be viewed in front view and the design that can be viewed in perspective are not combined. The fact that it is possible to visually recognize, by changing the viewing direction from one design to another design suddenly, high unexpectedness is obtained, and the added value of switching between different designs can be fully demonstrated, etc. It is an object of the invention.
このような目的を達成するために、本発明による化粧シートは、表面に照射された光を乱反射する梨地面が形成された第1の表面部分と、前記第1の表面部分以外の表面に形成され、一方向への反射光が主に得られる表面が形成された第2の表面部分と、前記第1及び第2の表面部分以外の表面に形成され、前記第2の表面部分における反射光の方向とは異なる他方向への反射光が主に得られる表面が形成された第３の表面部分とを少なくとも備え、前記第1の表面部分における凸部の頂点を他の表面部分と同一面上に形成し、前記第１の表面部分と当該第１の表面部分以外の表面のコントラスト差によって、正面視による第１の視認絵柄が形成され、前記第２の表面部分と前記第３の表面部分のコントラスト差によって、斜視による第２の視認絵柄が形成されることを特徴とする。 In order to achieve such an object, the decorative sheet according to the present invention is formed on a first surface portion on which a textured surface that irregularly reflects light irradiated on the surface is formed, and on a surface other than the first surface portion. The second surface portion on which a surface from which reflected light in one direction is mainly obtained is formed, and the reflected light on the second surface portion is formed on a surface other than the first and second surface portions. At least a third surface portion on which a surface from which reflected light in the other direction different from the direction is mainly obtained is formed, and the vertex of the convex portion in the first surface portion is flush with the other surface portion A first visual pattern is formed by a front view due to a contrast difference between the first surface portion and a surface other than the first surface portion, and the second surface portion and the third surface. Due to the difference in the contrast of the part, the second visual pattern by the perspective is It is formed.
本発明によると、化粧シートを正面視した場合には、梨地面と非梨地面とのコントラスト差によって第１の表面部分に応じた第１の視認絵柄が形成される。正面視した場合には、第２の表面部分と第３の表面部分とは大きなコントラスト差を示さないので、第２の表面部分と第３の表面部分との境界線に応じた第２の視認絵柄は隠すことができる。 According to the present invention, when the decorative sheet is viewed from the front, the first visual design corresponding to the first surface portion is formed by the contrast difference between the pear surface and the non-pear surface. When viewed from the front, since the second surface portion and the third surface portion do not show a large contrast difference, the second visual recognition according to the boundary line between the second surface portion and the third surface portion. The pattern can be hidden.
また、化粧シートを斜めから見た場合には、第２の表面部分と第３の表面部分との反射方向の違いによるコントラスト差によって、第２の表面部分と第３の表面部分との境界線に応じた第２の視認絵柄が形成される。この際、第1の表面部分における凸部の頂点を他の表面部分と同一面上に形成しているので、斜めから見た場合に、第１の表面部分の存在を第２の表面部分と第３の表面部分との反射方向の違いによるコントラスト差によって隠すことができる。 Further, when the decorative sheet is viewed obliquely, a boundary line between the second surface portion and the third surface portion is caused by a contrast difference due to a difference in reflection direction between the second surface portion and the third surface portion. A second visual image corresponding to the above is formed. At this time, since the apex of the convex portion in the first surface portion is formed on the same plane as the other surface portions, the presence of the first surface portion is defined as the second surface portion when viewed from an oblique direction. It can be hidden by the difference in contrast due to the difference in reflection direction from the third surface portion.
これによって、表面を正面視する場合を含めて、視認方向に応じて異なる絵柄を視認でき、正面視の場合に視認できる絵柄と斜視の場合に視認できる絵柄をそれぞれ独立に視認することができる。また、一つの絵柄から視認方向を変えるだけで急に他の絵柄に切り変わるようにできるので、高い意外性が得られ、異なる絵柄を切り換えるという付加価値を十分に発揮することができる。 Thus, different patterns can be visually recognized depending on the viewing direction, including the case where the surface is viewed from the front, and the images that can be viewed in the front view and the images that can be viewed in the perspective view can be independently viewed. In addition, since it is possible to suddenly switch from one pattern to another by simply changing the viewing direction, high unexpectedness can be obtained, and the added value of switching between different patterns can be fully exhibited.
以下、本発明の実施形態を図面に基づいて説明する。図１及び図２は、本発明の実施形態に係る化粧シートの構造を説明する説明図である。図１は、第１の表面部分ａ，第２の表面部分ｂ，第３の表面部分ｃの境界を破線で示した平面図であって、図２は、その断面図である（同図（ａ）は、図１におけるＸ−Ｘ断面図、同図（ｂ）は、拡大断面図）。ここに破線で示された絵柄は一例であって、特にこの絵柄に限定されることはなく、どのような絵柄を形成することも可能である。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG.1 and FIG.2 is explanatory drawing explaining the structure of the decorative sheet which concerns on embodiment of this invention. FIG. 1 is a plan view showing the boundaries of the first surface portion a, the second surface portion b, and the third surface portion c with broken lines, and FIG. 2 is a cross-sectional view thereof. a) is a cross-sectional view taken along line XX in FIG. 1, and FIG. The picture shown here by a broken line is an example, and is not particularly limited to this picture, and any picture can be formed.
図示の例では、第１の表面部分ａは、表面に照射された光を乱反射する梨地面が形成された表面部分であり、第２の表面部分ｂは、一方向への反射光が主に得られる表面が形成された表面部分であり、第３の表面部分ｃは、他方向への反射光が主に得られる表面が形成された表面部分である。 In the example shown in the figure, the first surface portion a is a surface portion on which a textured surface that irregularly reflects the light irradiated on the surface is formed, and the second surface portion b is mainly reflected light in one direction. The obtained surface is a surface portion on which the surface is formed, and the third surface portion c is a surface portion on which a surface from which reflected light in the other direction is mainly obtained is formed.
第１の表面部分ａは梨地面であって、それ以外の表面の非梨地面が第２の表面部分ｂ及び第３の表面部分ｃになっている。第２の表面部分ｂと第３の表面部分ｃは、例えば、異なる方向性を有する凹凸面によって形成することができる。この場合には、凹凸面に形成される斜面（反射面）が第２の表面部分ｂと第３の表面部分ｃとで異なる方向に向くように形成されている（図２の例では、第２の表面部分ｂの直線的な凹凸方向に沿った断面が記載されている）。 The first surface portion a is a pear surface, and the other non-pear surface is a second surface portion b and a third surface portion c. The 2nd surface part b and the 3rd surface part c can be formed by the uneven surface which has different directionality, for example. In this case, the inclined surface (reflecting surface) formed on the uneven surface is formed to face in different directions in the second surface portion b and the third surface portion c (in the example of FIG. 2 shows a cross section along the linear unevenness direction of the surface portion b of 2).
そして、第１の表面部分ａとそれ以外の表面部分の境界によって第１の視認絵柄（ここでは「◎」の絵柄）が形成されており、第２の表面部分ｂと第３の表面部分ｃの境界によって第２の視認絵柄（ここでは「Ａ」の絵柄）が形成されている。 A first visual pattern (here, “◎” pattern) is formed by the boundary between the first surface portion a and the other surface portions, and the second surface portion b and the third surface portion c. A second visual design pattern (here, “A” design) is formed by the boundary.
ここで重要な点は、図２（ｂ）に示すように、第1の表面部分ａにおける凸部の頂点が第２の表面部分ｂ及び第３の表面部分ｃと同一面上に形成されていることである。第２の表面部分ｂ及び第３の表面部分ｃを凹凸面とした場合には、第１の表面部分ａ，第２の表面部分ｂ，第３の表面分ｃの各頂点が同一平面上に形成されることになる。 The important point here is that, as shown in FIG. 2 (b), the apex of the convex portion in the first surface portion a is formed on the same plane as the second surface portion b and the third surface portion c. It is that you are. When the second surface portion b and the third surface portion c are uneven surfaces, the vertices of the first surface portion a, the second surface portion b, and the third surface portion c are on the same plane. Will be formed.
このような実施形態に係る化粧シートを正面視した場合には、図３に示すように、第１の表面部分ａとそれ以外の表面部分の境界によって形成される第１の視認絵柄のみが形成されることになる。これは、正面から見た場合には、第２の表面部分ｂと第３の表面部分ｃとは、反射方向に違いがあってもコントラストの違いとしては現れないからであり、正面視した場合には、第２の視認絵柄はほぼ完全に隠れた状態になる。 When the decorative sheet according to such an embodiment is viewed from the front, only the first visual image formed by the boundary between the first surface portion a and the other surface portion is formed as shown in FIG. Will be. This is because when viewed from the front, the second surface portion b and the third surface portion c do not appear as a difference in contrast even if there is a difference in the reflection direction. The second visual image is almost completely hidden.
一方、このような実施形態に係る化粧シートを斜視した場合には、図４に示すように、第２の表面部分ｂと第３の表面部分ｃの境界によって形成される第２の視認絵柄のみが形成されることになる。これは、斜めからみた場合には、反射方向の違いによって第２の表面部分ｂと第３の表面部分ｃでコントラストの違いが大きく現れて、第２の視認絵柄が浮き彫りにされることになるが、第1の表面部分ａにおける凸部の頂点を第２の表面部分ｂ及び第３の表面部分ｃと同一面上に形成することで、第１の表面部分ａと第２の表面部分ｂ、或いは第１の表面部分ａと第３の表面部分ｃとのコントラスト差は、前述した第２の表面部分ｂと第３の表面部分ｃとのコントラスト差に比べて無視できるほど小さくなるので、第１の視認絵柄はほぼ完全に隠れた状態になり、第２の視認絵柄のみが形成されることになる。 On the other hand, when the decorative sheet according to such an embodiment is perspectived, as shown in FIG. 4, only the second visual image formed by the boundary between the second surface portion b and the third surface portion c is used. Will be formed. This is because, when viewed from an oblique direction, a difference in contrast appears greatly between the second surface portion b and the third surface portion c due to a difference in reflection direction, and the second visual design pattern is highlighted. However, the first surface portion a and the second surface portion b are formed by forming the vertices of the convex portions on the first surface portion a on the same plane as the second surface portion b and the third surface portion c. Alternatively, the contrast difference between the first surface portion a and the third surface portion c is so small that it can be ignored as compared with the contrast difference between the second surface portion b and the third surface portion c described above. The first visual design is almost completely hidden, and only the second visual design is formed.
図示の例では、前述した非梨地面に第２の表面部分ｂと第３の表面部分ｃを形成しているが、これに加えて第４，第５の表面部分等を加えることができる。第４の表面部分を加える場合には、第２の表面部分と第３の表面部分と第４の表面部分とがそれぞれ異なる方向性を有する凹凸面にすることが有効である。その場合には、第２の表面部分と第３，第４の表面部分とのコントラスト差で一つの絵柄が視認でき、第３の表面部分と第２，第４の表面部分とのコントラスト差で一つの絵柄が視認でき、第４の表面部分と第２，第３の表面部分とのコントラスト差で一つの絵柄が視認できることになる。すなわち、異なる方向からの斜視で異なる絵柄が視認できることになる。 In the example shown in the figure, the second surface portion b and the third surface portion c are formed on the above-mentioned non-pear surface, but in addition to this, the fourth and fifth surface portions can be added. When the fourth surface portion is added, it is effective that the second surface portion, the third surface portion, and the fourth surface portion have an uneven surface having different directions. In that case, one pattern can be visually recognized by the contrast difference between the second surface portion and the third and fourth surface portions, and the contrast difference between the third surface portion and the second and fourth surface portions. One pattern can be visually recognized, and one pattern can be visually recognized by the difference in contrast between the fourth surface portion and the second and third surface portions. That is, a different pattern can be visually recognized by perspective from different directions.
このような実施形態によると、前述した特徴を有することで、表面を正面視する場合を含めて、視認方向に応じて異なる絵柄を視認でき、正面視の場合に視認できる絵柄と斜視の場合に視認できる絵柄をそれぞれ独立に視認することができる。また、一つの絵柄から視認方向を変えるだけで急に他の絵柄に切り変わるようにできるので、高い意外性が得られ、異なる絵柄を切り換えるという付加価値を十分に発揮することができる。 According to such an embodiment, by having the above-described features, it is possible to visually recognize different patterns depending on the viewing direction, including the case where the surface is viewed from the front. The visually recognizable pattern can be visually recognized independently. In addition, since it is possible to suddenly switch from one pattern to another by simply changing the viewing direction, high unexpectedness can be obtained, and the added value of switching between different patterns can be fully exhibited.
