Description

本発明は光による加飾効果を利用した装飾体、及びそれを蓋部として用いた収容箱に関する。   The present invention relates to a decorative body that utilizes a decorative effect by light, and a storage box that uses the decorative body as a lid.

快適性の向上や高級感の演出などを目的として車室内を光で加飾することが行われている。従来の加飾方法は、加飾領域に光を照射する方法（即ち光による照明）と、加飾領域自体を発光させる方法に大別される。前者の一例として特許文献１にはランプの光でアームレスト付近を照明する構成が開示されている。また、後者の一例として特許文献２には所望の形状を発光表示するスカッフプレートが開示されている。   Car interiors are decorated with light for the purpose of improving comfort and producing a high-class feel. Conventional decoration methods are roughly classified into a method of irradiating light on the decoration region (that is, illumination by light) and a method of causing the decoration region itself to emit light. As an example of the former, Patent Document 1 discloses a configuration in which the vicinity of an armrest is illuminated with light from a lamp. As an example of the latter, Patent Document 2 discloses a scuff plate that emits and displays a desired shape.

特許第３２４６２２１号公報Japanese Patent No. 3246221 特開２００１−１６３１１７号公報JP 2001-163117 A

以上の加飾方法では光源の発光状態に従って加飾領域の意匠が変化し、光源がオン（発光）のときにのみ光による加飾効果が奏される。即ち、１種類の加飾効果しか得られないものであり、単調で演出効果に乏しい。そこで本発明は、異なる２種類の加飾効果が発揮されることで演出効果が高い装飾体を簡易な構成で提供することを課題とする。   In the above decoration method, the design of the decoration region changes according to the light emission state of the light source, and the decoration effect by light is exhibited only when the light source is on (light emission). That is, only one type of decoration effect can be obtained, and it is monotonous and has a poor production effect. Then, this invention makes it a subject to provide the decoration body with a high production | presentation effect by simple structure by exhibiting two different types of decoration effects.

以上の課題を解決すべく、本発明は以下の構成からなる。即ち、
光源と、
表面の一部が前記光源に対向するように配置され、上面が発光面となる導光体と、
前記導光体の前記発光面上に配置され、印加電圧によって透視度が制御される調光層と、及び
前記調光層上に配置される光透過性カバーと、
を備える装飾体である。 In order to solve the above problems, the present invention has the following configuration. That is,
A light source;
A light guide that is arranged so that part of the surface faces the light source, and the upper surface is a light emitting surface;
A light control layer disposed on the light emitting surface of the light guide, the transparency of which is controlled by an applied voltage, and a light transmissive cover disposed on the light control layer;
Is a decorative body.

本発明の装飾体では光源の光が最終的に光透過性カバーの表面から放射することによって装飾体が発光し、これによって装飾効果（加飾）が発揮されることになるが、導光体の発光面上に調光層を配したことによって当該調光層への印加電圧を変えれば装飾体の発光状態を変化させることができる。即ち、異なる複数の加飾状態を作り出すことができ、また意外性も演出される。このように本発明の装飾体は調光層の利用によって高い演出効果を発揮する。   In the decorative body of the present invention, the light of the light source is finally emitted from the surface of the light-transmitting cover, so that the decorative body emits light, thereby exhibiting a decorative effect (decoration). If the voltage applied to the light control layer is changed by arranging the light control layer on the light emitting surface, the light emission state of the decorative body can be changed. That is, a plurality of different decoration states can be created, and unexpectedness is also produced. Thus, the decorative body of the present invention exhibits a high effect by using the light control layer.

本発明の装飾体は光源、導光体、調光層、及び光透過性カバーを備える。これらの各要素について以下に詳述する。   The decorative body of the present invention includes a light source, a light guide, a light control layer, and a light transmissive cover. Each of these elements will be described in detail below.

（光源）
光源は特に限定されるものではなく、ＬＥＤランプ、バルブ等を用いることができる。中でもＬＥＤランプを用いることが好ましい。ＬＥＤランプは小型であるため装飾体の小型化を図れるからである。また、発熱量が小さく、周囲の部材への熱の影響を少なくすることができるといった利点も有する。さらには、駆動電力が小さく、また長寿命であるといった利点も有する。ＬＥＤランプの種類は特に限定されず、砲弾型、チップ型等、種々のタイプのＬＥＤランプを採用できる。
光源の色は任意に選択できる。複数の光源を用い、これらを制御することにより発光色を変化させることも可能である。 (light source)
The light source is not particularly limited, and an LED lamp, a bulb, or the like can be used. Among them, it is preferable to use an LED lamp. This is because the LED lamp is small, so that the decorative body can be miniaturized. In addition, there is an advantage that the calorific value is small and the influence of heat on the surrounding members can be reduced. Furthermore, there are advantages such as low driving power and long life. The type of the LED lamp is not particularly limited, and various types of LED lamps such as a shell type and a chip type can be adopted.
The color of the light source can be arbitrarily selected. It is also possible to change the emission color by using a plurality of light sources and controlling them.

（導光体）
導光体はその表面の一部が光源に対向するように配置される。導光体に取り込まれた光は導光体内を導光した後、導光体の上面（発光面）から放射する。導光体の裏面（発光面と反対側の面）の一部に粗面加工、凹部ないし溝の形成、着色層や金属層の形成などの加飾処理が施されていることが好ましい。このような加飾処理が施された領域では、処理の種類に応じて光の反射や集中、散乱、及び／又は着色が生じ、その結果、導光体の発光面から放射される光が特有の態様を呈する。これによって例えば所望の図形や文字などを光で表示するといった加飾効果が奏される。尚、これらの加飾処理は単独又は二つ以上を組み合わせて用いられる。
導光体の裏面に上記の如き加飾処理を行うことに代えて又はこれに加えて、導光体の裏面側に加飾シートを配置することにしても良い。例えば所望の図形や文字の形の打ち抜き部を有する金属板を加飾シートとして利用できる。このような加飾シートを導光体の裏面に密着させて配置すれば、加飾シート表面の反射作用によって、金属色を帯びた光の中に所望の図形や文字が打ち抜き的に観察されるという発光態様となる。
導光体の材質は特に限定されない。例えばポリカーボネート、アクリル樹脂、エポキシ樹脂、ウレタン樹脂等の合成樹脂、ガラス等の無機材料で導光体を形成することができる。着色した光透過性材料（即ち、有色透明樹脂など）で導光体を構成してもよい。 (Light guide)
The light guide is arranged such that a part of its surface faces the light source. The light taken into the light guide is guided through the light guide and then emitted from the upper surface (light emitting surface) of the light guide. It is preferable that a part of the back surface (surface opposite to the light emitting surface) of the light guide is subjected to a decoration process such as roughening, formation of recesses or grooves, formation of a colored layer or a metal layer. In the region subjected to such a decoration treatment, light reflection, concentration, scattering, and / or coloring occurs depending on the type of treatment, and as a result, the light emitted from the light emitting surface of the light guide is unique. The aspect of this is exhibited. As a result, for example, a decoration effect of displaying a desired figure, character, or the like with light is produced. In addition, these decorating processes are used individually or in combination of 2 or more.
Instead of or in addition to performing the decoration process as described above on the back surface of the light guide, a decoration sheet may be disposed on the back surface side of the light guide. For example, a metal plate having a punched portion having a desired figure or character shape can be used as the decorative sheet. If such a decorative sheet is placed in close contact with the back surface of the light guide, a desired figure or character is punched and observed in the light with a metallic color due to the reflective action of the decorative sheet surface. It becomes the light emission mode.
The material of the light guide is not particularly limited. For example, the light guide can be formed of a synthetic resin such as polycarbonate, acrylic resin, epoxy resin, or urethane resin, or an inorganic material such as glass. You may comprise a light guide with the colored light-transmitting material (namely, colored transparent resin etc.).

（調光層）
本発明では印加電圧によって透視度（透過率）が制御される調光層が使用される。このような調光層としていわゆるエレクトロクロミックガラスや液晶方式の調光シート（又は調光ガラス）を用いることができる。中でも応答性などの面から液晶方式の調光シート（又は調光ガラス）を採用することが好ましい。液晶方式の調光シート（又は調光ガラス）を採用することによって瞬間的な意匠の変化も実現できる。液晶方式の調光シートは、液晶層を一対の透明電極膜で挟んだ構成からなり（調光ガラスは各透明電極膜の外側にガラスを配した構造を有する）、無通電時には不透視状態（光遮蔽状態）であり、通電させると透視状態（光透過状態）になる。本発明では、不透視状態の平行光線透過率が約１〜約１５％の範囲にあり、透視状態の平行光線透過率が約６０〜約８０％の範囲にある調光シートを好適に使用することができる。このような調光シートとしてウムフィルム（登録商標、日本板硝子株式会社製）を用いることができる。尚、調光シート（又は調光ガラス）は電圧の制御によって透視度を調整することも可能である。調光シートのこのような性質を利用して、無通電時と通電時との間で意匠が変化するだけでなく、印加電圧に応じて意匠が変化するように本発明の装飾体を構成することもできる。 (Light control layer)
In the present invention, a light control layer whose transparency (transmittance) is controlled by an applied voltage is used. As such a light control layer, so-called electrochromic glass or a liquid crystal type light control sheet (or light control glass) can be used. Among these, it is preferable to employ a liquid crystal light control sheet (or light control glass) in terms of responsiveness. By adopting a liquid crystal light control sheet (or light control glass), an instantaneous design change can be realized. A liquid crystal type light control sheet has a structure in which a liquid crystal layer is sandwiched between a pair of transparent electrode films (the light control glass has a structure in which a glass is arranged outside each transparent electrode film) and is in a non-transparent state when not energized ( Light shielding state), and when energized, it enters a see-through state (light transmitting state). In this invention, the light control sheet | seat in which the parallel light transmittance of an opaque state exists in the range of about 1 to about 15%, and the parallel light transmittance of a transparent state exists in the range of about 60 to about 80% is used suitably. be able to. Umm film (registered trademark, manufactured by Nippon Sheet Glass Co., Ltd.) can be used as such a light control sheet. In addition, the light control sheet (or light control glass) can also adjust a transparency by voltage control. Utilizing such properties of the light control sheet, the decorative body of the present invention is configured such that the design changes not only between the time of no energization and the time of energization, but also the design changes according to the applied voltage. You can also.

調光層は導光体の発光面上に配置される。調光層によって導光体の発光面全体が被覆されるように、又は調光層によって導光体の発光面が部分的に被覆されるように構成される。前者の構成では導光体の発光面から放射された光の全てが調光層による調光作用を受ける。一方、後者の構成では、導光体の発光面から放射された光の一部は調光層の影響を受けることなく、調光層の上に配置される光透過性カバーを通過し外部放射することになる。従って、当該構成では調光層によって調光された光と調光されない光の２種類の光が観察されることになる。これによって装飾性に一層優れた意匠を構成することが可能である。例えば導光体の発光面の周縁部を除く領域を被覆するように調光層を形成すれば、周縁部のみが発光態様の異なる意匠が作り出される。同様に、導光体の発光面において調光層の被覆領域（又は非被覆領域）を図形や文字などの形にすれば、所望の図形や文字などが発光表示される発光態様を作り出すことも可能である。   The light control layer is disposed on the light emitting surface of the light guide. The entire light emitting surface of the light guide is covered with the light control layer, or the light emitting surface of the light guide is partially covered with the light control layer. In the former configuration, all of the light emitted from the light emitting surface of the light guide is subjected to a dimming action by the dimming layer. On the other hand, in the latter configuration, a part of the light emitted from the light emitting surface of the light guide is not affected by the light control layer, and passes through the light-transmitting cover disposed on the light control layer and is externally radiated. Will do. Therefore, in the said structure, two types of light of the light adjusted by the light control layer and the light which is not light-controlled is observed. As a result, it is possible to construct a design with even better decorativeness. For example, if the light control layer is formed so as to cover the region excluding the peripheral portion of the light emitting surface of the light guide, designs having different light emission modes are created only at the peripheral portion. Similarly, if the covering region (or non-covering region) of the light control layer is formed into a shape such as a figure or a character on the light emitting surface of the light guide, a light emitting mode in which a desired figure or character is displayed and emitted can be created. Is possible.

（光透過性カバー）
光透過性カバーは調光層の上に配置される。光透過性カバーによってエレクトロクロミック型調光シートが保護されることになる。光透過性カバーの材質は良好な光透過性が発揮される限り特に限定されない。例えばポリカーボネート、アクリル樹脂、エポキシ樹脂、ウレタン樹脂等の合成樹脂、ガラス等の無機材料で光透過性カバーを形成することができる。着色した光透過性材料（即ち、有色透明樹脂など）で光透過性カバーを構成してもよい。 (Light transmissive cover)
The light transmissive cover is disposed on the light control layer. The electrochromic light control sheet is protected by the light transmissive cover. The material of the light transmissive cover is not particularly limited as long as good light transmittance is exhibited. For example, the light-transmitting cover can be formed of a synthetic resin such as polycarbonate, acrylic resin, epoxy resin, or urethane resin, or an inorganic material such as glass. The light transmissive cover may be made of a colored light transmissive material (that is, a colored transparent resin or the like).

（装飾体を利用した収容箱）
本発明の装飾体の好ましい適用対象の一つとして収容箱（例えば車室内に設置されるコンソールボックスやグローブボックス）が挙げられる。本発明の装飾体を収容箱に適用する場合、例えば収容箱の蓋部を本発明の装飾体で構成する。かかる装飾体では調光層への通電状態の切り換えによって、蓋部を通して収納部内が見えない状態（無通電状態）から見える状態（通電時）への変化を可逆的に行うことができる。これによって意外性の演出、利便性の向上、高級感の付与などの効果が奏される。また、車室内の収容箱（例えばコンソールボックス）など、運転時以外はその内部が観察されることが好ましくない収容箱に適用すればセキュリティー効果も得られる。具体的には例えば、コンソールボックスの蓋部に本発明の装飾体を適用し、イグニッションのオンに連動して調光層に通電するように構成すれば、運転時のみ蓋部を介してコンソールボックスの内部を観察可能となる。
ここで、装飾体を構成する導光体と調光層を蓋部の可動部に配置し、光源を収容箱の本体側に配置することにし、蓋部が閉状態から開状態に移行する際、光源の光放射側が開放されて光源の光が収容箱内を照明するように構成することができる。かかる構成によれば、収容箱の蓋部を開いたときに収容箱内が照明されることによって利便性が向上するとともに光による演出効果が発揮される。 (Containment box using decorative body)
An example of a preferable application object of the decorative body of the present invention is a storage box (for example, a console box or a glove box installed in a vehicle interior). When the decorative body of the present invention is applied to a storage box, for example, the lid portion of the storage box is configured with the decorative body of the present invention. In such a decorative body, by switching the energized state to the light control layer, it is possible to reversibly change from a state in which the inside of the storage unit cannot be seen through the lid (non-energized state) to a state in which it is visible (during energization). As a result, effects such as production of unexpectedness, improvement of convenience, and provision of a high-class feeling are exhibited. In addition, a security effect can also be obtained if the present invention is applied to a storage box such as a storage box (for example, a console box) in a passenger compartment where it is not preferable to observe the interior of the vehicle except during operation. Specifically, for example, if the decorative body of the present invention is applied to the lid portion of the console box and the dimming layer is energized in conjunction with the ignition being turned on, the console box is passed through the lid portion only during operation. The inside can be observed.
Here, when the light guide and the light control layer constituting the decorative body are arranged on the movable part of the lid, and the light source is arranged on the main body side of the storage box, the lid moves from the closed state to the open state. The light emission side of the light source can be opened, and the light of the light source can illuminate the inside of the storage box. According to such a configuration, when the lid of the storage box is opened, the interior of the storage box is illuminated, so that convenience is improved and an effect effect by light is exhibited.

本発明の実施例を図１〜図３に示す。この実施例は、本発明の装飾体を蓋部に適用した自動車用センターコンソールボックスである。図１は実施例に係るセンターコンソールボックス１の斜視図、図２は図１のＡ−Ａ線位置での断面図、図３はセンターコンソールボックス１の発光態様を説明する図である。   An embodiment of the present invention is shown in FIGS. This embodiment is an automobile center console box in which the decorative body of the present invention is applied to a lid. FIG. 1 is a perspective view of a center console box 1 according to the embodiment, FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG.

センターコンソールボックス１は上方が取り出し口となる収容部２０を備える。図２に示すように収容部２０の取り出し口を覆う蓋部１０は導光板１１、調光シート１２、及び意匠レンズ（光透過性カバー）１３が順に積層した構造を有する。当該構造はその外縁部において上下方向に枠体１４で狭持されている。尚、符号２１は蓋部１０の開閉操作用のスイッチである。
導光板１１は無色透明のアクリル樹脂製であり、その裏面側には平面視で特定形状の凹部（加飾加工部）１１ａが形成されている。また、導光板１１の裏面の周縁部には粗面加工が施されている。一方、導光板１１の左右端面１１ｂに沿ってＬＥＤランプ３０が配置される。この例では合計４個のＬＥＤランプ３０を使用し、一つの端面１１ｂから二個のＬＥＤランプ３０の光を導入することにしている。ＬＥＤランプ３０は白色光を発する。白色発光のＬＥＤランプに限らず、様々な発光色のＬＥＤランプを採用することができる。異なる発光色のＬＥＤランプを組み合わせて使用してもよい。このような構成によればグラデーション効果など混色による演出を行うことも可能である。
ＬＥＤランプ３０は制御回路を介して車両側の電源に接続されており、イグニッションの動作状態に連動した点灯制御を受ける（詳細は後述）。 The center console box 1 includes an accommodating portion 20 whose upper side is a take-out port. As shown in FIG. 2, the lid portion 10 that covers the outlet of the housing portion 20 has a structure in which a light guide plate 11, a light control sheet 12, and a design lens (light transmissive cover) 13 are sequentially stacked. The structure is held by the frame 14 in the vertical direction at the outer edge. Reference numeral 21 denotes a switch for opening and closing the lid 10.
The light guide plate 11 is made of a colorless and transparent acrylic resin, and a concave portion (decoration processing portion) 11a having a specific shape is formed on the back surface side in a plan view. In addition, the peripheral surface of the back surface of the light guide plate 11 is roughened. On the other hand, the LED lamps 30 are arranged along the left and right end surfaces 11 b of the light guide plate 11. In this example, a total of four LED lamps 30 are used, and light from two LED lamps 30 is introduced from one end face 11b. The LED lamp 30 emits white light. Not only a white light emitting LED lamp but also various light emitting LED lamps can be adopted. You may use combining the LED lamp of a different luminescent color. According to such a configuration, it is also possible to perform effects by color mixing such as a gradation effect.
The LED lamp 30 is connected to a power source on the vehicle side via a control circuit, and is subjected to lighting control that is linked to the operation state of the ignition (details will be described later).

導光体１１の上面側はその周縁部を除いて調光シート１２で被覆された状態となる。調光シート１２はネマチック液晶層を一対の透明導電膜フィルムで挟んだ構造を備え、通電時に透視状態（平行光線透過率が約７０％）となり、無通電時に不透視状態（平行光線透過率が約５％）となる。通電状態と無通電状態の切り換えはイグニッションの動作状態に連動する（詳細は後述）。   The upper surface side of the light guide 11 is in a state of being covered with the light control sheet 12 except for its peripheral edge. The light control sheet 12 has a structure in which a nematic liquid crystal layer is sandwiched between a pair of transparent conductive films, and is in a see-through state (parallel light transmittance is about 70%) when energized, and in a non-permeable state (parallel light transmittance is not energized). About 5%). Switching between the energized state and the non-energized state is linked to the operation state of the ignition (details will be described later).

意匠レンズ１３は無色透明のポリカーボネート樹脂製である。意匠レンズ１３の上面側は緩やかな凸曲面形状を有する。面意匠レンズの上面（意匠面）に強化処理や耐候処理などを施してもよい。   The design lens 13 is made of a colorless and transparent polycarbonate resin. The upper surface side of the design lens 13 has a gentle convex curved surface shape. The upper surface (design surface) of the surface design lens may be subjected to a strengthening process, a weather resistance process, or the like.

以上の構成の蓋部１０の発光態様は次の通りとなる。まず、イグニッションスイッチがオフ（運転前）の状態では蓋部１０内の調光シート１２は通電されない。そのため調光シート１２は不透視状態であり、蓋部１０は枠体１４部分を除いて乳白色で観察される。これによって、蓋部１０を介して収容部２０内が外部から見えず、セキュリティー効果が得られる。尚、調光シート１２と同様、ＬＥＤランプ３０にも電圧は印加されず、ＬＥＤランプは消灯状態である。
キーの挿入によってイグニッションスイッチがオンになると、これに連動してＬＥＤランプ３０が点灯し、その数秒後には調光シート１２も通電状態となる。ＬＥＤランプ３０が点灯すると（調光シート１２は無通電状態）ＬＥＤランプ３０の光が導光板１１に導入される。導入光の一部は導光体裏面の周縁部に施された粗面加工によって、導光体１１の上面周縁部（調光シート１２で被覆されない領域）を介して上方に出射する。このようにして取り出された光は意匠レンズ１３を通って最終的に外部放射する。これによって蓋部１０は枠体１４の内側に沿ってライン状に発光する（図３（ａ））。尚、図３（ａ）の斜線部１５が発光領域である。調光シート１２への通電が開始されると（ＬＥＤランプ３０は点灯状態を維持する）調光シート１２は不透視状態から透視状態に変化する。その結果、蓋部１０は枠体１４部分を除いて光透過性となる。この状態では蓋部１０を介して外部より収納部２０内が観察可能である。一方、導光体１１内に取り込まれたＬＥＤランプ３０の光の一部が、導光体裏面に形成された凹部１１ａのエッジに集中し、及びそこで反射・拡散されることによって図３（ｂ）に示すように所望の文字１６（この例ではＣＯＯＬ）が発光表示される。尚、調光シート１２への印加電圧を短時間で最大電圧までリニアに増加させることによって、フェードイン効果を得つつ、瞬間的な状態変化による意外性を演出している。
エンジン停止後、イグニションスイッチがオフにされると調光シート１２及びＬＥＤランプ３０への通電状態が解除され、蓋部１０は再び不透視状態（枠体部分を除いて乳白色）となる。
以上のように、イグニッションスイッチがオンになるとまずライン状の光で蓋部１０が加飾された後、蓋部１０が透視状態に変化するとともに所望の文字が浮かび上がるという演出が行われる。このように光による演出が行われ、同時に意匠の連続的且つ瞬間的な変化が生ずる結果、センターコンソールボックスのデザイン性が高められ、また高級感や意外性が演出される。さらには、運転時に収納部内の収納物を確認できることによる利便性の向上といった効果も発揮される。 The light emission mode of the lid 10 having the above configuration is as follows. First, the light control sheet 12 in the lid portion 10 is not energized when the ignition switch is off (before operation). Therefore, the light control sheet 12 is in a non-transparent state, and the lid 10 is observed in milky white except for the frame body 14 portion. As a result, the inside of the accommodating portion 20 cannot be seen from the outside through the lid portion 10, and a security effect is obtained. As with the light control sheet 12, no voltage is applied to the LED lamp 30, and the LED lamp is off.
When the ignition switch is turned on by inserting a key, the LED lamp 30 is turned on in conjunction with this, and the light control sheet 12 is also energized several seconds later. When the LED lamp 30 is turned on (the light control sheet 12 is in a non-energized state), the light from the LED lamp 30 is introduced into the light guide plate 11. A part of the introduced light is emitted upward through the upper surface peripheral portion (region not covered with the light control sheet 12) of the light guide 11 by roughening the peripheral portion of the rear surface of the light guide. The light thus extracted is finally emitted outside through the design lens 13. As a result, the lid 10 emits light in a line along the inner side of the frame body 14 (FIG. 3A). The shaded area 15 in FIG. 3A is a light emitting area. When energization to the light control sheet 12 is started (the LED lamp 30 maintains the lighting state), the light control sheet 12 changes from the non-transparent state to the transparent state. As a result, the lid 10 is light transmissive except for the frame 14 portion. In this state, the inside of the storage portion 20 can be observed from the outside through the lid portion 10. On the other hand, a part of the light of the LED lamp 30 taken into the light guide 11 is concentrated on the edge of the recess 11a formed on the back surface of the light guide, and is reflected and diffused there, whereby FIG. ), The desired character 16 (COOL in this example) is lit and displayed. In addition, by increasing the voltage applied to the light control sheet 12 linearly up to the maximum voltage in a short time, an unexpected effect due to an instantaneous state change is produced while obtaining a fade-in effect.
When the ignition switch is turned off after the engine is stopped, the energized state of the light control sheet 12 and the LED lamp 30 is released, and the lid portion 10 becomes opaque again (milky white except for the frame portion).
As described above, when the ignition switch is turned on, the lid portion 10 is first decorated with line-shaped light, and then the lid portion 10 changes to a see-through state and a desired character emerges. As described above, the effect by the light is performed, and at the same time, the design of the center console box is enhanced as a result of the continuous and instantaneous change of the design. Furthermore, the effect of the convenience improvement by being able to confirm the storage thing in a storage part at the time of a driving | operation is also exhibited.

この実施例では調光シート１２の通電タイミングとＬＥＤランプ３０の点灯タイミングをずらしたが、これらを同期させることにしてもよい。
また、この実施例ではイグニッションスイッチのオンオフに連動させて調光シート１２及びＬＥＤランプ３０の駆動状態を制御したが、車幅灯又はヘッドライトの操作に連動ないし同期させて調光シート１２及び／又はＬＥＤランプ３０の駆動状態を制御することにしてもよい。或いは、イグニッションスイッチ、車幅灯、及びヘッドライトの中の二つ以上に連動ないし同期させて調光シート１２等の駆動状態を制御してもよい。 In this embodiment, the energization timing of the light control sheet 12 and the lighting timing of the LED lamp 30 are shifted, but they may be synchronized.
In this embodiment, the driving state of the light control sheet 12 and the LED lamp 30 is controlled in conjunction with the on / off of the ignition switch. However, the light control sheet 12 and / or Alternatively, the driving state of the LED lamp 30 may be controlled. Or you may control the drive state of the light control sheet | seat 12 grade | etc., Interlocking with or synchronizing with two or more in an ignition switch, a vehicle width light, and a headlight.

本発明の他の実施例を図４及び５に示す。図４はこの実施例に係るセンターコンソールボックス２の断面図（図２に対応する）、図５は蓋部５０が開状態のセンターコンソールボックス２の斜視図である。尚、説明の便宜上、これらの図面において上記実施例と同一の部材には同一の符号を付す。センターコンソールボックス２の蓋部５０では導光板１１の左右端部が枠体１４に挟み込まれた状態となっており、導光板１１の左右端面１１ｂは露出する。そして、この導光体露出面に対向する位置においてセンターコンソールボックス本体４０内にＬＥＤランプ３０が組み込まれている。このような構成によって、蓋部５０が閉状態にあるときにＬＥＤランプ３０が点灯すると導光体１１の左右端面１１ｂから光の導入が行われることになる。これによって上記実施例と同様の光による演出が行われる。一方、スイッチ操作によって蓋部５０が開状態になったときは（図５）ＬＥＤランプ３０の前方が開放されることになり、ＬＥＤランプ３０の光は収容部２０内に照射する。これによって収容部２０内が照明され、収容部２０内の視認性が高まる。このように本実施例の構成ではＬＥＤランプ３０の光を二つの目的、即ち蓋部５０の加飾と収容部２０内の照明に利用することにし、センターコンソールボックス２のデザイン性及び利便性の向上を実現している。   Another embodiment of the present invention is shown in FIGS. 4 is a cross-sectional view of the center console box 2 according to this embodiment (corresponding to FIG. 2), and FIG. 5 is a perspective view of the center console box 2 with the lid 50 open. For convenience of explanation, the same reference numerals are given to the same members as those in the above embodiment in these drawings. In the lid portion 50 of the center console box 2, the left and right end portions of the light guide plate 11 are sandwiched between the frames 14, and the left and right end surfaces 11b of the light guide plate 11 are exposed. The LED lamp 30 is incorporated in the center console box body 40 at a position facing the light guide exposed surface. With such a configuration, when the LED lamp 30 is lit when the lid portion 50 is in the closed state, light is introduced from the left and right end surfaces 11b of the light guide 11. As a result, an effect by light similar to that in the above embodiment is performed. On the other hand, when the lid portion 50 is opened by the switch operation (FIG. 5), the front of the LED lamp 30 is opened, and the light from the LED lamp 30 is irradiated into the housing portion 20. As a result, the interior of the housing portion 20 is illuminated, and the visibility within the housing portion 20 is enhanced. As described above, in the configuration of the present embodiment, the light of the LED lamp 30 is used for two purposes, that is, decoration of the lid 50 and illumination in the housing 20, and the design and convenience of the center console box 2 are improved. Improvement has been realized.
