Description

本発明は、加飾パネル構造及びその製造方法に関する。 The present invention relates to a decorative panel structure and a method for manufacturing the same.

従来、オートクルーズ用のレーダ波（ミリ波）を透過するエンブレム（加飾パネル構造）が知られている（例えば、特許文献１参照）。このエンブレムは、フロントグリルの車幅方向略中央にあって、そのロゴタイプ（logotype）等が金属光沢を有しながらも後方のミリ波レーダ装置から発信されるミリ波が透過可能となっている。具体的には、このエンブレムは、平面視でロゴタイプ等の図柄をかたどった加飾部材と、この加飾部材が嵌り込む凹部が形成されたパネル状の透明カバー部材と、を有している。また、加飾部材は、樹脂ベース上にインジウム蒸着フィルムが付与されて構成され、透明カバー部材には、凹部を除く領域にマスク層がグラビア印刷されている。そして、透明カバー部材の凹部に接着剤を介して加飾部材が嵌め込まれることでエンブレムが得られることとなる。
このようなエンブレムは、透明カバー部材側から見ると、ロゴタイプ等の図柄が、グラビア印刷されたマスク層を背景に金属光沢にて浮かび上がる。そして、この図柄を形成するインジウム蒸着フィルム（金属光沢部）は、微視的に海島状になって広がるインジウム粒子同士の間（海部）でミリ波の透過を可能にする。 Conventionally, an emblem (decorative panel structure) that transmits a radar wave (millimeter wave) for auto cruise is known (see, for example, Patent Document 1). This emblem is located approximately in the center of the front grille in the vehicle width direction, and while its logotype has a metallic luster, it is capable of transmitting millimeter waves transmitted from the rear millimeter wave radar device. .. Specifically, this emblem has a decorative member in the shape of a logotype or the like in a plan view, and a panel-shaped transparent cover member in which a recess into which the decorative member is fitted is formed. .. Further, the decorative member is configured by applying an indium-deposited film on a resin base, and the transparent cover member is gravure-printed with a mask layer in a region excluding recesses. Then, the emblem can be obtained by fitting the decorative member into the recess of the transparent cover member via the adhesive.
When viewed from the transparent cover member side, such an emblem has a pattern such as a logotype with a metallic luster against the background of a gravure-printed mask layer. The indium-deposited film (metallic luster portion) that forms this pattern enables the transmission of millimeter waves between the indium particles that microscopically form a sea island and spread (the sea portion).

特許第４２２４７９４号公報Japanese Patent No. 4224794

ところで、従来のエンブレム（例えば、特許文献１参照）においては、透明カバー部材の凹部に、図柄をかたどった加飾部材を嵌め込む際に、凹部内の接着剤は、この加飾部材に押されて凹部外へと移動する。しかしながら、このようなエンブレムにおいては、凹部内での接着剤の移動量や移動方向の制御が難しく、透明カバー部材の凹部に対する加飾部材の押し込み量や、押し込み方向などが変動するおそれがある。そして、これらの押し込み量や、押し込み方向などが変動すると、加飾部材と透明カバー部材との相対距離が変動し、又は凹部に対して加飾部材がずれて嵌め込まれるおそれがある。これにより従来のエンブレム（加飾パネル構造）においては、得られる製品ごとに、透明カバー部材側に浮かび上がるロゴタイプの美観やレーダ波透過性能などのエンブレムの品質にバラツキを生じるおそれがある。 By the way, in the conventional emblem (see, for example, Patent Document 1), when the decorative member in the shape of a pattern is fitted into the concave portion of the transparent cover member, the adhesive in the concave portion is pressed by the decorative member. Move out of the recess. However, in such an emblem, it is difficult to control the amount and direction of movement of the adhesive in the recess, and the amount of pushing the decorative member into the recess of the transparent cover member, the pushing direction, and the like may fluctuate. If the pushing amount, pushing direction, or the like fluctuates, the relative distance between the decorative member and the transparent cover member may fluctuate, or the decorative member may be misaligned and fitted with respect to the recess. As a result, in the conventional emblem (decorative panel structure), the quality of the emblem such as the aesthetic appearance of the logotype that emerges on the transparent cover member side and the radar wave transmission performance may vary depending on the obtained product.

本発明の課題は、従来と比べて品質のバラツキをより確実に抑制することができる加飾パネル構造及びその製造方法を提供することにある。 An object of the present invention is to provide a decorative panel structure and a method for manufacturing the same, which can more reliably suppress the variation in quality as compared with the conventional one.

前記課題を解決した本発明の加飾パネル構造は、パネル状の透明カバー部材と、前記透明カバー部材の両面のうち一面側に形成される凹部と、前記凹部を除いて前記透明カバー部材の一面側に形成される着色層と、前記透明カバー部材の前記凹部に接着剤を介在させて嵌め込まれる加飾部材と、を有し、前記加飾部材は、前記凹部の開口部周囲のパネル面に沿うように張り出す縁部を一体に備えていることを特徴とする。
また、前記課題を解決した本発明の加飾パネル構造の製造方法は、パネル状の透明カバー部材の両面のうち一面側に形成される凹部に加飾部材が嵌め込まれた加飾パネル構造の製造方法であって、前記凹部に前記加飾部材を嵌め込む際に、前記加飾部材の外周部に設けた縁部を前記凹部の開口部周囲に支持させることを特徴とする。 The decorative panel structure of the present invention that solves the above problems includes a panel-shaped transparent cover member, a recess formed on one side of both sides of the transparent cover member, and one surface of the transparent cover member excluding the recess. It has a colored layer formed on the side and a decorative member that is fitted by interposing an adhesive in the concave portion of the transparent cover member, and the decorative member is formed on a panel surface around an opening of the concave portion. It is characterized by having an integral edge that overhangs along the line.
Further, the method for manufacturing a decorative panel structure of the present invention that solves the above problems is to manufacture a decorative panel structure in which a decorative member is fitted in a recess formed on one side of both sides of a panel-shaped transparent cover member. The method is characterized in that, when the decorative member is fitted into the concave portion, an edge portion provided on the outer peripheral portion of the decorative member is supported around the opening of the concave portion.

本発明によれば、従来と比べて品質のバラツキをより確実に抑制することができる加飾パネル構造及びその製造方法を提供することができる。 INDUSTRIAL APPLICABILITY According to the present invention, it is possible to provide a decorative panel structure and a method for manufacturing the same, which can more reliably suppress quality variation as compared with the prior art.

次に、本発明を実施するための形態（本実施形態）の加飾パネル構造及びその製造方法について適宜図面を参照しつつ詳細に説明する。
以下では、本実施形態の加飾パネル構造である車両用のエンブレムを例にとって説明した後に、このエンブレムの製造方法について説明する。なお、以下の説明における前後上下の方向は、エンブレムを取り付ける車体の前後上下の方向を基準とする。
なお、本実施形態のエンブレムは、加飾パネル構造の一例であり、後に詳しく説明するように、透明カバー部材に形成された凹部に縁部を有する加飾部材が嵌め込まれたことを主な特徴とする。したがって、本発明は、このエンブレムに限定されずに、このような特徴点を有する種々の加飾パネル構造に適用することができる。 Next, the decorative panel structure of the embodiment (the present embodiment) for carrying out the present invention and the method for manufacturing the decorative panel structure will be described in detail with reference to the drawings as appropriate.
In the following, an emblem for a vehicle, which is a decorative panel structure of the present embodiment, will be described as an example, and then a method for manufacturing the emblem will be described. In the following description, the front-back and up-down directions are based on the front-back and up-down directions of the vehicle body to which the emblem is attached.
The emblem of the present embodiment is an example of a decorative panel structure, and as will be described in detail later, the main feature is that a decorative member having an edge is fitted into a recess formed in the transparent cover member. And. Therefore, the present invention is not limited to this emblem, and can be applied to various decorative panel structures having such features.

＜エンブレム＞
図１は、本実施形態に係るエンブレム１（加飾パネル構造）を有する車体前部の部分拡大正面図である。図２は、図１のII−II断面図である。
図１に示すように、エンブレム１は、車体前部に配置されるフロントグリル（ラジエータグリルともいう）２０の車幅方向の略中央に配置されている。
フロントグリル２０は、図示しないフロントバルクヘッドの前方に配置されるとともに、フロントバンパフェース２１の上部に設けられている。 <Emblem>
FIG. 1 is a partially enlarged front view of a front portion of a vehicle body having an emblem 1 (decorative panel structure) according to the present embodiment. FIG. 2 is a sectional view taken along line II-II of FIG.
As shown in FIG. 1, the emblem 1 is arranged substantially in the center of the front grille (also referred to as a radiator grille) 20 arranged in the front portion of the vehicle body in the vehicle width direction.
The front grill 20 is arranged in front of the front bulkhead (not shown) and is provided on the upper part of the front bumper face 21.

図２に示すように、フロントグリル２０の後面には、図示しないレーダマウントを介してレーダ装置２２が取り付けられている。具体的には、レーダ装置２２は、フロントグリル２０に設けられた開口を介してエンブレム１の真後に配置されている。
ちなみに、本実施形態でのレーダ装置２２は、車両前方に向かって、例えば、波長１〜１０ｍｍ程度のレーダ波（ミリ波）を発信するものを想定しているがこれに限定するものではない。そして、レーダ装置２２は、このような送信波を出力し、対応物にて反射された反射波を、電子スキャン方式を用いて複数の受信アンテナにて受信する。これによりレーダ装置２２は、反射波の受信結果をオートクルーズシステム（図示省略）に供することとなる。 As shown in FIG. 2, a radar device 22 is attached to the rear surface of the front grill 20 via a radar mount (not shown). Specifically, the radar device 22 is arranged directly behind the emblem 1 through an opening provided in the front grill 20.
Incidentally, the radar device 22 in the present embodiment is assumed to emit a radar wave (millimeter wave) having a wavelength of, for example, about 1 to 10 mm toward the front of the vehicle, but the present invention is not limited to this. Then, the radar device 22 outputs such a transmitted wave, and receives the reflected wave reflected by the corresponding object with a plurality of receiving antennas by using an electronic scanning method. As a result, the radar device 22 supplies the reception result of the reflected wave to the auto cruise system (not shown).

そして、このようなレーダ波（ミリ波）が透過可能なエンブレム１は、図２に示すように、透明カバー部材２と、縁部４が設けられた加飾部材３と、背面部材５と、を主に備えている。また、エンブレム１は、後記の所定位置に第一の加飾層６と、第二の加飾層７と、接着剤層８と、をさらに備えている。
なお、第一の加飾層６は、特許請求の範囲にいう「着色層」に相当する。また、第二の加飾層７は、加飾部材３を構成し、特許請求の範囲にいう「金属調加飾層」を形成する。 As shown in FIG. 2, the emblem 1 capable of transmitting such a radar wave (millimeter wave) includes a transparent cover member 2, a decorative member 3 provided with an edge portion 4, a back surface member 5, and the like. Mainly equipped with. Further, the emblem 1 further includes a first decorative layer 6, a second decorative layer 7, and an adhesive layer 8 at predetermined positions described later.
The first decorative layer 6 corresponds to the "colored layer" in the claims. Further, the second decorative layer 7 constitutes the decorative member 3 and forms the "metal-like decorative layer" as defined in the claims.

（透明カバー部材）
図２に示すように、透明カバー部材２は、エンブレム１の外周部を縁取る後記の背面部材５を除いて、エンブレム１の前面部の殆どを占めるように配置されている。
ちなみに、このような透明カバー部材２によれば、図２に示すように、エンブレム１の前側からユーザが見ると、後記する第一の加飾層６と、後記する透明の接着剤層８によって透明カバー部材２の裏面（後面）に接着される加飾部材３（第二の加飾層７）とを見通すことができる。 (Transparent cover member)
As shown in FIG. 2, the transparent cover member 2 is arranged so as to occupy most of the front surface portion of the emblem 1 except for the back surface member 5 described later, which borders the outer peripheral portion of the emblem 1.
By the way, according to such a transparent cover member 2, as shown in FIG. 2, when the user sees from the front side of the emblem 1, the first decorative layer 6 described later and the transparent adhesive layer 8 described later are used. It is possible to see through the decorative member 3 (second decorative layer 7) adhered to the back surface (rear surface) of the transparent cover member 2.

つまり、図１は、不図示の透明カバー部材２を介して、エンブレム１の前側（図１の紙面手前側）から第一の加飾層６（着色層）と、加飾部材３（第二の加飾層７（金属調加飾層））とを見た様子を示している。
そして、本実施形態での透明カバー部材２は、図１においては、エンブレム１の外周部を縁取る背面部材５の内側で、第一の加飾層６と、加飾部材３（第二の加飾層７）とが占める領域の平面形状に略等しく、楕円の平面形状を呈している。
このような透明カバー部材２の外周部には、図２に示すように、ステップ状の段差１１が形成されている。この段差１１には、後記するように、背面部材５の外周部が外側から嵌り込むように一体成形されることとなる。 That is, FIG. 1 shows the first decorative layer 6 (colored layer) and the decorative member 3 (second) from the front side of the emblem 1 (the front side of the paper surface in FIG. 1) via the transparent cover member 2 (not shown). It shows a state of seeing the decorative layer 7 (metal-like decorative layer) of.
In FIG. 1, the transparent cover member 2 in the present embodiment has the first decorative layer 6 and the decorative member 3 (second) inside the back member 5 that borders the outer peripheral portion of the emblem 1. It is substantially equal to the planar shape of the area occupied by the decorative layer 7), and has an elliptical planar shape.
As shown in FIG. 2, a step-shaped step 11 is formed on the outer peripheral portion of the transparent cover member 2. As will be described later, the step 11 is integrally molded so that the outer peripheral portion of the back surface member 5 is fitted from the outside.

このような透明カバー部材２の裏面側（一面側）には、図２に示すように、加飾部材３が嵌め込まれる凹部１２が形成されている。
そして、透明カバー部材２の裏面側（一面側）には、凹部１２を除く裏面全体に、前記の第一の加飾層６（着色層）が形成されている。 As shown in FIG. 2, a recess 12 into which the decorative member 3 is fitted is formed on the back surface side (one surface side) of the transparent cover member 2.
On the back surface side (one surface side) of the transparent cover member 2, the first decorative layer 6 (colored layer) is formed on the entire back surface excluding the recess 12.

本実施形態での第一の加飾層６は、着色樹脂の塗膜を想定している。塗料としては、特に制限はなく、例えば、ウレタン系、アクリル系、ポリエステル系、ラッカー系、メラミン系等が挙げられる。
塗装方法としては、特に制限はなく、例えば、スクリーン印刷、グラビア印刷などの印刷法や、所定のマスキングを施した上でのスプレー法等の塗布法が挙げられる。
塗膜の厚さは、特に制限はなく、例えば、５〜５０μｍ程度に設定することができる。
このような第一の加飾層６は、エンブレム１に浮かび上がる図柄の背景色を設定する。 The first decorative layer 6 in the present embodiment is assumed to be a coating film of a colored resin. The paint is not particularly limited, and examples thereof include urethane-based, acrylic-based, polyester-based, lacquer-based, and melamine-based paints.
The painting method is not particularly limited, and examples thereof include a printing method such as screen printing and gravure printing, and a coating method such as a spray method after applying a predetermined masking.
The thickness of the coating film is not particularly limited and can be set to, for example, about 5 to 50 μm.
Such a first decorative layer 6 sets the background color of the pattern that emerges in the emblem 1.

本実施形態での透明カバー部材２は、ポリカーボネートからなる樹脂製のものを想定している。ただし、透明カバー部材２の材料は、レーダ波を透過するとともに、可視光を透過するいわゆる透明（半透明、着色透明を含む）であれば特に制限はなく、例えば、アクリル樹脂、ポリスチレン、ポリ塩化ビニル等の熱可塑性樹脂を使用することもできる。
なお、このような透明カバー部材２の表面側（他面側）には、図示しないがハードコート層を形成することもできる。このハードコート層としては、使用する透明カバー部材２の材料に応じて公知のものを使用することができ、例えばポリカーボネートからなる透明カバー部材２に適用するハードコート層としては、例えばシリコーンハードコート塗膜（オルガノポリシロキサン塗膜）が挙げられる。 The transparent cover member 2 in the present embodiment is assumed to be made of a resin made of polycarbonate. However, the material of the transparent cover member 2 is not particularly limited as long as it is so-called transparent (including translucent and colored transparent) that transmits radar waves and visible light, and is, for example, acrylic resin, polystyrene, or polyvinyl chloride. Thermoplastic resins such as vinyl can also be used.
Although not shown, a hard coat layer can be formed on the surface side (other surface side) of such a transparent cover member 2. As the hard coat layer, known ones can be used depending on the material of the transparent cover member 2 to be used. For example, as the hard coat layer applied to the transparent cover member 2 made of polycarbonate, for example, a silicone hard coat coating can be used. Examples include a film (organopolysiloxane coating film).

（加飾部材及び縁部）
加飾部材３と縁部４とは、図２に示すように、ベース部材（インナベース）１３を共通にし、このベース部材１３の透明カバー部材２と向き合う側の表面に第二の加飾層７を設けて構成されている。
図１に示すように、加飾部材３は、平面視でのエンブレム１において、ロゴタイプ（logotype）、ロゴタイプを囲む枠部等の図柄を形成する。
ちなみに、本実施形態での加飾部材３は、図１に示す平面視で、エンブレム１の外周部を縁取る背面部材５の内側で、白抜きにて表された部分である。この加飾部材３は、後記の第一の加飾層６（図１中の網掛け部分）によって枠取りや縁取りがなされている。 (Decorative members and edges)
As shown in FIG. 2, the decorative member 3 and the edge portion 4 share a base member (inner base) 13, and a second decorative layer is formed on the surface of the base member 13 on the side facing the transparent cover member 2. 7 is provided and configured.
As shown in FIG. 1, the decorative member 3 forms a design such as a logotype and a frame portion surrounding the logotype in the emblem 1 in a plan view.
Incidentally, the decorative member 3 in the present embodiment is a portion shown in white inside the back surface member 5 that borders the outer peripheral portion of the emblem 1 in the plan view shown in FIG. The decorative member 3 is framed or bordered by the first decorative layer 6 (shaded portion in FIG. 1) described later.

そして、加飾部材３は、図２に示すように、透明カバー部材２の凹部１２に嵌め込まれている。
加飾部材３は、後記する縁部４と一体成形されたベース部材１３と、このベース部材１３の表面に形成された第二の加飾層７とで形成されている。 Then, as shown in FIG. 2, the decorative member 3 is fitted in the recess 12 of the transparent cover member 2.
The decorative member 3 is formed of a base member 13 integrally molded with an edge portion 4 described later, and a second decorative layer 7 formed on the surface of the base member 13.

ベース部材１３は、加飾部材３と縁部４の表面に付される第二の加飾層７の下地となる。ベース部材１３としては、例えば熱可塑性樹脂の成形品を使用することができるが、中でも耐候性、耐衝撃性に富むアクリロニトリル・エチレン・スチレン樹脂からなる成形品が好ましい。 The base member 13 serves as a base for the second decorative layer 7 attached to the surfaces of the decorative member 3 and the edge portion 4. As the base member 13, for example, a molded product of a thermoplastic resin can be used, but among them, a molded product made of acrylonitrile, ethylene, and styrene resin having excellent weather resistance and impact resistance is preferable.

本実施形態での第二の加飾層７は、レーダ波（ミリ波）の透過可能な金属調加飾層を想定している。
具体的には、第二の加飾層７は、ベース部材１３の表面に金属調加飾フィルムを三次元表面加飾工法(Three dimension Overlay Method;ＴＯＭ）にて付与したものである。
この工法では、大気圧を利用した真空成形にてベース部材１３の表面（凹部１２側に向き合う面）に沿うように、金属調加飾フィルムが三次元的に熱成形される。
金属調加飾フィルムとしては、例えば、インジウム蒸着層を含む積層複合フィルムを使用することができる。ちなみに、金属調加飾フィルムとしては、インジウム蒸着層が１０〜１００ｎｍ程度で、全厚が２５μｍ〜１００μｍ程度の市販品を使用することができる。 The second decorative layer 7 in the present embodiment is assumed to be a metallic decorative layer capable of transmitting radar waves (millimeter waves).
Specifically, the second decorative layer 7 is obtained by applying a metallic decorative film to the surface of the base member 13 by a three-dimensional surface decoration method (TOM).
In this method, the metallic decorative film is three-dimensionally thermoformed along the surface of the base member 13 (the surface facing the concave portion 12 side) by vacuum forming using atmospheric pressure.
As the metallic decorative film, for example, a laminated composite film including an indium-deposited layer can be used. Incidentally, as the metallic decorative film, a commercially available product having an indium-deposited layer of about 10 to 100 nm and a total thickness of about 25 μm to 100 μm can be used.

縁部４は、図２に示すように、加飾部材３と一体に成形されている。つまり、縁部４と加飾部材３とは、前記のように、共通するベース部材１３の表面に、第二の加飾層７としての金属調加飾フィルムが付与されて形成されている。
具体的には、縁部４は、凹部１２に嵌め込まれた加飾部材３から凹部１２の開口部周囲のパネル面２ａに沿うように張り出すように形成されている。
そして、縁部４（図２参照）は、図１中、隠れ線（点線）にて示すように、加飾部材３の周縁に沿ってフランジ状に連続して延びるように形成されている。 As shown in FIG. 2, the edge portion 4 is integrally molded with the decorative member 3. That is, the edge portion 4 and the decorative member 3 are formed by applying a metallic decorative film as the second decorative layer 7 to the surface of the common base member 13 as described above.
Specifically, the edge portion 4 is formed so as to project from the decorative member 3 fitted in the recess 12 along the panel surface 2a around the opening of the recess 12.
The edge portion 4 (see FIG. 2) is formed so as to extend continuously in a flange shape along the peripheral edge of the decorative member 3 as shown by a hidden line (dotted line) in FIG.

このような加飾部材３は、凹部１２に接着剤層８を介して嵌め込まれるとともに、縁部４は、凹部１２の開口部周囲で接着剤層８を介して第一の加飾層６（着色層）上に配置されている。
そして、縁部４は、接着剤層８上で段差１４を形成している。
なお、本実施形態での接着剤層８を構成する接着剤は、少なくとも凹部１２内で加飾部材３と透明カバー部材２とを接合可能な透明性を有するものであれば特に制限はない。
接着剤層８の厚さとしては、特に制限はないが、例えば１００μｍ〜２ｍｍ程度に設定することができる。

FIG. 3F is a process explanatory view for fitting the decorative member 3 into the recess 12 of the transparent cover member 2.

本実施形態での製造方法においては、図３Ａに示すように、まず所定形状の透明カバー部材２を用意する。この透明カバー部材２は、射出成形などの公知の樹脂成形法にて得ることができる。
そして、透明カバー部材２の一面側には、凹部１２を除く範囲で、第一の加飾層６（着色層）が形成される。具体的には、透明カバー部材２の一面側には、前記のように、着色樹脂の塗膜が形成される。 In the manufacturing method of the present embodiment, as shown in FIG. 3A, first, a transparent cover member 2 having a predetermined shape is prepared. The transparent cover member 2 can be obtained by a known resin molding method such as injection molding.
Then, a first decorative layer 6 (colored layer) is formed on one surface side of the transparent cover member 2 in a range excluding the recess 12. Specifically, as described above, a coating film of colored resin is formed on one surface side of the transparent cover member 2.

次に、この製造方法においては、図３Ｂに示すように、透明カバー部材２の一面側に接着剤層８を形成する。接着剤層８は、凹部１２内及び第一の加飾層６を含めて透明カバー部材２の一面側の全てに前記の接着剤が塗布されることで形成される。 Next, in this manufacturing method, as shown in FIG. 3B, the adhesive layer 8 is formed on one surface side of the transparent cover member 2. The adhesive layer 8 is formed by applying the adhesive to all of the one side of the transparent cover member 2 including the inside of the recess 12 and the first decorative layer 6.

その一方で、この製造方法においては、図３Ｃに示すベース部材１３を用意する。
このベース部材１３は、前記のように、加飾部材３（図２参照）と縁部４（図２参照）とに対応するように形成され、透明カバー部材２（図３Ｂ参照）の凹部１２（図３Ｂ参照）に嵌り込む部分と、この凹部１２（図３Ｂ参照）の開口部周囲のパネル面２ａ（図３Ｂ参照）に沿うように張り出す部分とを一体に有している。 On the other hand, in this manufacturing method, the base member 13 shown in FIG. 3C is prepared.
As described above, the base member 13 is formed so as to correspond to the decorative member 3 (see FIG. 2) and the edge portion 4 (see FIG. 2), and the recess 12 of the transparent cover member 2 (see FIG. 3B). It integrally has a portion that fits into (see FIG. 3B) and a portion that projects along the panel surface 2a (see FIG. 3B) around the opening of the recess 12 (see FIG. 3B).

次いで、この工程では、図３Ｃに示すように、ベース部材１３の表面、つまり透明カバー部材２（図２参照）と向き合う側の面に、図２に示す第二の加飾層７（金属調加飾層）を形成するための金属調加飾フィルム１６が三次元表面加飾工法(Three dimension Overlay Method;ＴＯＭ）にて付与される。
これによりベース部材１３の表面１３ａには、金属調加飾フィルム１６が密着することによって、第二の加飾層７（金属調加飾層）が形成される。そして、ベース部材１３の開口部１３ｂには、この開口部１３ｂを塞ぐように、第二の加飾層７の形成に関与しない余分な金属調加飾フィルム１６が残される。この余分な金属調加飾フィルム１６は、後の工程で切り取られる。 Next, in this step, as shown in FIG. 3C, the surface of the base member 13, that is, the surface on the side facing the transparent cover member 2 (see FIG. 2), is the second decorative layer 7 (metal tone) shown in FIG. A metallic decorative film 16 for forming a decorative layer) is applied by a three-dimensional surface decoration method (TOM).
As a result, the metal-like decorative film 16 is in close contact with the surface 13a of the base member 13, so that the second decorative layer 7 (metal-like decorative layer) is formed. Then, in the opening 13b of the base member 13, an extra metallic decorative film 16 that does not participate in the formation of the second decorative layer 7 is left so as to close the opening 13b. This extra metallic decorative film 16 is cut off in a later step.

この金属調加飾フィルム１６は、前記のように、例えばインジウム蒸着フィルム（インジウム蒸着層）を含む積層複合フィルムを使用することができる。
図３Ｄに示すように、このようなインジウム蒸着フィルム１７は、例えば平面視で長径が５０ｎｍ〜５００ｎｍ程度のインジウム粒子１７ａが海島状に広がるように形成される。 As the metallic decorative film 16, for example, a laminated composite film including an indium-deposited film (indium-deposited layer) can be used.
As shown in FIG. 3D, such an indium-deposited film 17 is formed so that, for example, indium particles 17a having a major axis of about 50 nm to 500 nm spread in a sea-island shape in a plan view.

インジウム蒸着フィルム１７を含む積層複合フィルムからなる第二の加飾層７（図２参照）は、金属光沢を有している。そして、第二の加飾層７（図２参照）は、インジウム蒸着フィルム１７におけるインジウム粒子１７ａ同士の間に形成される海部１７ｂにてミリ波の透過を可能にする。
そして、図３Ｅに示すように、縁部４に対応するベース部材１３の外端で、つまり図３Ｅの矢示Ｃｔ部分にて余分な金属調加飾フィルム１６が切り取られることによって、図２に示す加飾部材３と縁部４との一体成形物が得られる。 The second decorative layer 7 (see FIG. 2) made of a laminated composite film containing the indium-deposited film 17 has a metallic luster. The second decorative layer 7 (see FIG. 2) enables transmission of millimeter waves at the sea portion 17b formed between the indium particles 17a in the indium-deposited film 17.
Then, as shown in FIG. 3E, the excess metal-like decorative film 16 is cut off at the outer end of the base member 13 corresponding to the edge portion 4, that is, at the arrow Ct portion of FIG. 3E, so that FIG. 2 shows. An integrally molded product of the decorative member 3 and the edge portion 4 shown is obtained.

次に、この製造方法においては、図３Ｆに示すように、透明カバー部材２の凹部１２に加飾部材３が嵌め込まれ、透明カバー部材２に対して加飾部材３と縁部４とが接着剤層８を形成する接着剤によって接着される。
そして、凹部１２に加飾部材３が嵌め込まれる際に、加飾部材３の外周部に設けられた縁部４は、接着剤層８を介して凹部１２の開口部周囲に支持される。 Next, in this manufacturing method, as shown in FIG. 3F, the decorative member 3 is fitted into the recess 12 of the transparent cover member 2, and the decorative member 3 and the edge portion 4 are adhered to the transparent cover member 2. It is adhered by the adhesive forming the agent layer 8.
Then, when the decorative member 3 is fitted into the recess 12, the edge portion 4 provided on the outer peripheral portion of the decorative member 3 is supported around the opening of the recess 12 via the adhesive layer 8.

次に、この製造方法においては、図示は省略するが、所定の金型内に、図３Ｆに示す加飾部材３が嵌め込まれた透明カバー部材２が配置されるとともに、この金型内に所定の溶融樹脂材料が注入される。これにより、金型内には、インサート部材としての加飾部材３を有する透明カバー部材２が背面部材５（図２参照）にて裏打ちされたエンブレム１（図２参照）が得られることとなる。 Next, in this manufacturing method, although not shown, a transparent cover member 2 in which the decorative member 3 shown in FIG. 3F is fitted is arranged in a predetermined mold, and is predetermined in the mold. The molten resin material of is injected. As a result, an emblem 1 (see FIG. 2) in which the transparent cover member 2 having the decorative member 3 as the insert member is lined with the back member 5 (see FIG. 2) can be obtained in the mold. ..

≪作用効果≫
次に、本実施形態のエンブレム１（加飾パネル構造）及びその製造方法の奏する作用効果について説明する。 ≪Action effect≫
Next, the operation and effect of the emblem 1 (decorative panel structure) of the present embodiment and the manufacturing method thereof will be described.

本実施形態のエンブレム１（加飾パネル構造）においては、加飾部材３は、透明カバー部材２の凹部１２の開口部周囲に沿うように張り出す縁部４を一体に備えている。そして、縁部４は、凹部１２に加飾部材３を嵌め込む際に、凹部１２の開口部周囲に支持される。このことについて図を参照しながら詳しく説明する。 In the emblem 1 (decorative panel structure) of the present embodiment, the decorative member 3 integrally includes an edge portion 4 projecting along the periphery of the opening of the recess 12 of the transparent cover member 2. Then, the edge portion 4 is supported around the opening of the recess 12 when the decorative member 3 is fitted into the recess 12. This will be explained in detail with reference to the figure.

図４Ａは、本実施形態において、透明カバー部材２の凹部１２に対して加飾部材３の位置決めを行う際の縁部４周りの部分拡大図である。図４Ｂは、透明カバー部材２の凹部１２に加飾部材３を嵌め込む際の縁部４周りの部分拡大図である。図５Ａは、比較例に係るエンブレム１０において、透明カバー部材２の凹部１２に対して加飾部材３の位置決めを行う際の図４Ａに対応する部分拡大図である。図５Ｂは、比較例に係るエンブレム１０において、透明カバー部材２の凹部１２に加飾部材３を嵌め込む際の図４Ｂに対応する部分拡大図である。 FIG. 4A is a partially enlarged view around the edge portion 4 when the decorative member 3 is positioned with respect to the recess 12 of the transparent cover member 2 in the present embodiment. FIG. 4B is a partially enlarged view around the edge portion 4 when the decorative member 3 is fitted into the recess 12 of the transparent cover member 2. FIG. 5A is a partially enlarged view corresponding to FIG. 4A when the decorative member 3 is positioned with respect to the recess 12 of the transparent cover member 2 in the emblem 10 according to the comparative example. FIG. 5B is a partially enlarged view corresponding to FIG. 4B when the decorative member 3 is fitted into the recess 12 of the transparent cover member 2 in the emblem 10 according to the comparative example.

まず、比較例について説明すると、図５Ａに示すように、エンブレム１０は、本実施形態のエンブレム１（図４Ａ参照）と異なって、加飾部材３に縁部４（図４Ａ参照）を有していない。
図５Ａに示すように、透明カバー部材２の凹部１２に対して位置決めされた加飾部材３が、白抜き矢印の方向に凹部１２内に押し込まれていく。この際、エンブレム１０においては、凹部１２内での接着剤８ａの移動量や移動方向の制御が難しく、加飾部材３の押し込み量や、押し込み方向などが変動するおそれがある。 First, to explain a comparative example, as shown in FIG. 5A, the emblem 10 has an edge portion 4 (see FIG. 4A) on the decorative member 3 unlike the emblem 1 (see FIG. 4A) of the present embodiment. Not.
As shown in FIG. 5A, the decorative member 3 positioned with respect to the recess 12 of the transparent cover member 2 is pushed into the recess 12 in the direction of the white arrow. At this time, in the emblem 10, it is difficult to control the moving amount and the moving direction of the adhesive 8a in the recess 12, and the pushing amount and the pushing direction of the decorative member 3 may fluctuate.

その結果、図５Ｂに示すように、比較例のエンブレム１０は、加飾部材３の押し込み量や、押し込み方向などが変動することによって、加飾部材３と透明カバー部材２との相対距離が変動し、又は凹部１２に対して加飾部材３がずれて嵌め込まれることがある。
これによりエンブレム１０は、得られる製品ごとに、透明カバー部材２側から見通した加飾部材３の美観等の品質にバラツキを生じることとなる。 As a result, as shown in FIG. 5B, in the emblem 10 of the comparative example, the relative distance between the decorative member 3 and the transparent cover member 2 changes due to the change in the pushing amount of the decorative member 3, the pushing direction, and the like. Alternatively, the decorative member 3 may be misaligned and fitted into the recess 12.
As a result, the emblem 10 will vary in quality such as the aesthetic appearance of the decorative member 3 as seen from the transparent cover member 2 side for each product obtained.

これに対して本実施形態のエンブレム１によれば、図４Ａに示すように、加飾部材３が透明カバー部材２の凹部１２に対して位置決めされる際に、縁部４は、凹部１２の開口部周囲のパネル面２ａに対向するように配置される。
そして、図４Ａに示すように、加飾部材３が透明カバー部材２の凹部１２に対して白抜き矢印の方向に押し込まれていく。
そして、図４Ｂに示すように、加飾部材３が凹部１２内に押し込まれていくにつれて、縁部４は、接着剤８ａにて形成される接着剤層８を介して凹部１２の開口部周囲に対する押圧力Ｆ１に応じた反力Ｆ２を開口部周囲から受ける。
つまり、縁部４は、凹部１２に対する加飾部材３の過度の押し込みを規制する。これによりエンブレム１は、比較例のエンブレム１０（図５Ｂ参照）とは異なって、加飾部材３の押し込み量や、押し込み方向などの変動が防止される。その結果、エンブレム１は、得られる製品ごとの品質のバラツキを抑制することができる。 On the other hand, according to the emblem 1 of the present embodiment, as shown in FIG. 4A, when the decorative member 3 is positioned with respect to the recess 12 of the transparent cover member 2, the edge portion 4 is formed on the recess 12. It is arranged so as to face the panel surface 2a around the opening.
Then, as shown in FIG. 4A, the decorative member 3 is pushed into the recess 12 of the transparent cover member 2 in the direction of the white arrow.
Then, as shown in FIG. 4B, as the decorative member 3 is pushed into the recess 12, the edge portion 4 is formed around the opening of the recess 12 via the adhesive layer 8 formed by the adhesive 8a. A reaction force F2 corresponding to the pressing force F1 is received from around the opening.
That is, the edge portion 4 regulates the excessive pushing of the decorative member 3 into the recess 12. As a result, unlike the emblem 10 of the comparative example (see FIG. 5B), the emblem 1 is prevented from fluctuating in the pushing amount and pushing direction of the decorative member 3. As a result, the emblem 1 can suppress the variation in quality for each obtained product.

また、本実施形態のエンブレム１においては、図２に示したように、加飾部材３と縁部４とが、ベース部材１３の表面にレーダ波透過可能な第二の加飾層７（金属調加飾層）が付与されて構成されている。そして、透明カバー部材２の凹部１２の開口部周囲においては、透明カバー部材２側から順番に第一の加飾層６（着色層）、透明な接着剤層８、第二の加飾層７（金属調加飾層）及び縁部４の順番で積層されている。 Further, in the emblem 1 of the present embodiment, as shown in FIG. 2, the decorative member 3 and the edge portion 4 have a second decorative layer 7 (metal) capable of transmitting radar waves to the surface of the base member 13. It is configured with a decorative layer). Then, around the opening of the recess 12 of the transparent cover member 2, the first decorative layer 6 (colored layer), the transparent adhesive layer 8, and the second decorative layer 7 are arranged in order from the transparent cover member 2 side. (Metallic decorative layer) and edge 4 are laminated in this order.

ところで、比較例のエンブレム１０は、図５Ｂに示すように、透明カバー部材２側から見た際に、透明カバー部材２における第一の加飾層６（着色層）の端部と加飾部材３との間に介在する透明な接着剤層８を介してエンブレム１０の裏側へと見通してしまう。つまり、加飾部材３にて形成されるエンブレム１０における図柄の輪郭と、第一の加飾層６（着色層）が形成する背景との境が不明確となる。 By the way, as shown in FIG. 5B, the emblem 10 of the comparative example has the end portion of the first decorative layer 6 (colored layer) in the transparent cover member 2 and the decorative member when viewed from the transparent cover member 2 side. It is visible to the back side of the emblem 10 through the transparent adhesive layer 8 interposed between the three and the emblem 10. That is, the boundary between the outline of the pattern in the emblem 10 formed by the decorative member 3 and the background formed by the first decorative layer 6 (colored layer) becomes unclear.

これに対して本実施形態のエンブレム１では、図４Ｂに示すように、第一の加飾層６（着色層）の端部と加飾部材３との間に介在する透明な接着剤層８を見通す先には、第一の加飾層６（着色層）の端部で見切った縁部４における第二の加飾層７（金属調加飾層）が存在する。
したがって、このエンブレム１によれば、第二の加飾層７（金属調加飾層）にて形成される図柄の輪郭と、第一の加飾層６（着色層）が形成する背景との境が明確となって、エンブレム１の美観が向上する。 On the other hand, in the emblem 1 of the present embodiment, as shown in FIG. 4B, the transparent adhesive layer 8 interposed between the end portion of the first decorative layer 6 (colored layer) and the decorative member 3. There is a second decorative layer 7 (metal-like decorative layer) at the edge 4 cut off at the end of the first decorative layer 6 (colored layer).
Therefore, according to this emblem 1, the outline of the pattern formed by the second decorative layer 7 (metal-like decorative layer) and the background formed by the first decorative layer 6 (colored layer). The boundary becomes clear and the aesthetics of Emblem 1 are improved.

また、図５Ｂに示す比較例のエンブレム１０においては、前記のように加飾部材３がずれて傾くことによって、得られる製品ごとに第二の加飾層７（金属調加飾層）におけるミリ波透過性能にバラツキを生じるおそれがある。 Further, in the emblem 10 of the comparative example shown in FIG. 5B, when the decorative member 3 is displaced and tilted as described above, the millimeter in the second decorative layer 7 (metal-like decorative layer) is used for each product obtained. There is a risk of variation in wave transmission performance.

これに対して図４Ｂに示す本実施形態のエンブレム１によれば、前記のように加飾部材３がずれて傾くことが防止されるので、第二の加飾層７（金属調加飾層）におけるミリ波透過性能のバラツキを抑制することができる。 On the other hand, according to the emblem 1 of the present embodiment shown in FIG. 4B, since the decorative member 3 is prevented from being displaced and tilted as described above, the second decorative layer 7 (metal-like decorative layer) is prevented. ), It is possible to suppress the variation in the millimeter wave transmission performance.

また、本実施形態のエンブレム１においては、第二の加飾層７（金属調加飾層）が三次元表面加飾成形樹脂層である。
このようなエンブレム１は、図３Ｅに示したように、三次元表面加飾工法にて第二の加飾層７（金属調加飾層）が形成された後に、余分な金属調加飾フィルム１６が縁部４の矢示IIIｅ部分にて切り取られる。 Further, in the emblem 1 of the present embodiment, the second decorative layer 7 (metal-like decorative layer) is a three-dimensional surface decorative molded resin layer.
As shown in FIG. 3E, such an emblem 1 is an extra metallic decorative film after the second decorative layer 7 (metal-like decorative layer) is formed by the three-dimensional surface decoration method. 16 is cut off at the arrow IIIe portion of the edge 4.

ところで、比較例のエンブレム１０の第二の加飾層７（金属調加飾層）が、三次元表面加飾成形樹脂層である場合には、図５Ｂに示す切断部１８にて余分な金属調加飾フィルム１６が切り取られることとなる。つまり、比較例のエンブレム１０においては、金属調加飾フィルム１６の切断部１８が第一の加飾層６（着色層）の端部と加飾部材３との間に介在する透明な接着剤層８を介して見えてしまう。これによりこの切断部１８が、透明カバー部材２側から見た加飾部材３のエッジ部の美観を損ねることがある。 By the way, when the second decorative layer 7 (metal-like decorative layer) of the emblem 10 of the comparative example is a three-dimensional surface decorative molded resin layer, excess metal is formed at the cut portion 18 shown in FIG. 5B. The decorative film 16 will be cut off. That is, in the emblem 10 of the comparative example, the cut portion 18 of the metallic decorative film 16 is a transparent adhesive interposed between the end portion of the first decorative layer 6 (colored layer) and the decorative member 3. It is visible through layer 8. As a result, the cut portion 18 may impair the aesthetic appearance of the edge portion of the decorative member 3 as seen from the transparent cover member 2 side.

これに対して本実施形態のエンブレム１においては、図４Ｂに示すように、第一の加飾層６（着色層）によって、金属調加飾フィルム１６の切断部１８が見えることがない。これによりエンブレム１においては、金属調加飾フィルム１６の切断部１８が美観を損ねることはない。 On the other hand, in the emblem 1 of the present embodiment, as shown in FIG. 4B, the cut portion 18 of the metallic decorative film 16 is not visible due to the first decorative layer 6 (colored layer). As a result, in the emblem 1, the cut portion 18 of the metallic decorative film 16 does not spoil the aesthetic appearance.

また、本実施形態のエンブレム１においては、図２に示したように、背面部材５が、透明カバー部材２の一面側から透明カバー部材２の周側面部２ｂを外側から囲むように一体成形されている。
このようなエンブレム１によれば、透明カバー部材２と背面部材５との接合強度が一段と高められる。 Further, in the emblem 1 of the present embodiment, as shown in FIG. 2, the back surface member 5 is integrally molded from one side of the transparent cover member 2 so as to surround the peripheral side surface portion 2b of the transparent cover member 2 from the outside. ing.
According to such an emblem 1, the joint strength between the transparent cover member 2 and the back surface member 5 is further increased.

以上、本発明の実施形態について説明したが、本発明は前記した実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々変更することができる。
前記実施形態のエンブレム１においては、透明カバー部材２に形成される第一の加飾層６が着色樹脂で形成され、加飾部材３及び縁部４に設けられる第二の加飾層７が金属調加飾層にて形成されている。
しかしながら、エンブレム１においては、第一の加飾層６を金属調加飾層にて形成し、第二の加飾層７を着色樹脂の塗膜にて形成することもできる。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

However, in the emblem 1, the first decorative layer 6 can be formed of a metallic decorative layer, and the second decorative layer 7 can be formed of a colored resin coating film.

また、前記実施形態では、縁部４は、連続するフランジ状に形成されているが、これに限定されずに、例えば加飾部材３が形成する図柄が囲み込む領域の内周側角隅などに部分的に形成されるものであってもよい。 Further, in the above-described embodiment, the edge portion 4 is formed in a continuous flange shape, but the edge portion 4 is not limited to this, for example, an inner peripheral side corner of a region surrounded by a pattern formed by the decorative member 3. It may be partially formed on the flange.

また、前記実施形態では、車体前部に配置されるエンブレム１について説明したが、本発明の加飾パネル構造は、これが取り付けられる対象物を車体に限定するものではない。したがって、加飾パネル構造は、船舶、航空機などの他の移動体に取り付けることもできる。また、加飾パネル構造は、対象物の前後左右上下のいずれにも配置可能である。 Further, in the above-described embodiment, the emblem 1 arranged in the front portion of the vehicle body has been described, but the decorative panel structure of the present invention does not limit the object to which the emblem 1 is attached to the vehicle body.
