As compared with the case of the case, the striate body can emit light with uniform brightness, and the decorativeness can be improved. When the outer flexible locking portion is provided in parallel with the central axis of the linear body to be held, the linear body and the linear body holder are continuously locked in the axial direction by the flexible locking portion. Therefore, it is possible to reliably prevent the striatum and the striatum holder from coming off.

以下に本発明の実施の形態の具体例を図面を用いて詳細に説明する。図１は、本発明に係る線条体固定構造の一実施形態を示す。本実施形態の線条体固定構造は、装飾用のライトファイバ（線条体）１と、ライトファイバ１に光を供給する光源（不図示）と、ライトファイバ１を保持するファイバホルダ（線条体ホルダ）３と、このファイバホルダ３を介してライトファイバ１を固定させるパネル（被取付体）１３とから構成されている。ライトファイバ１とファイバホルダ３とからファイバアッセンブリ１１が構成されている。   Specific examples of embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of a striatum fixing structure according to the present invention. The linear body fixing structure of the present embodiment includes a decorative light fiber (wire body) 1, a light source (not shown) that supplies light to the light fiber 1, and a fiber holder (wires) that holds the light fiber 1. Body holder) 3 and a panel (attached body) 13 for fixing the light fiber 1 through the fiber holder 3. A fiber assembly 11 is composed of the light fiber 1 and the fiber holder 3.

ライトファイバ１は、一端から内部に送り込まれた光をファイバ１内で均一に繰り返し反射させ、自身が光源でコントロールされた明るさで発光する発光体であり、プラスチックを構成材料として長尺かつ大径に成形されたものである。プラスチック製のライトファイバ１は、可撓性に優れるため、取り扱いの自由度が高く、任意の方向に湾曲させることが可能である。このようなライトファイバ１は、一例として、コア材をアクリル系樹脂、クラッド材をフッ素系樹脂で構成することができる。ライトファイバ１の長さは任意であり、長尺物を一体成形したり、複数の短尺物を光コネクタを用いて相互接続して用いたりすることも可能である。   The light fiber 1 is a light-emitting body that uniformly and repeatedly reflects light transmitted from one end inside the fiber 1 and emits light with brightness controlled by a light source. It is molded into a diameter. Since the plastic light fiber 1 is excellent in flexibility, it has a high degree of freedom in handling and can be bent in any direction. In such a light fiber 1, as an example, the core material can be made of acrylic resin and the clad material can be made of fluorine resin. The length of the light fiber 1 is arbitrary, and a long object can be integrally formed, or a plurality of short objects can be interconnected using an optical connector.

ライトファイバ１は、太いもので直径１０ｍｍ程度のものが安定して製造されるようになっている。現在では、さらに太いものでも製造可能になっている。ファイバ径の太いものは、相互接続する際の軸ずれを吸収することができる。また、光の接続損失が少なく、ファイバ端面の研磨加工も容易であり、細いものに比べて取扱性が良好である。   A light fiber 1 having a diameter of about 10 mm is stably manufactured. At present, even thicker ones can be manufactured. A fiber having a large fiber diameter can absorb an axial deviation when interconnected. In addition, the optical connection loss is small, the fiber end face is easily polished, and the handleability is better than a thin one.

なお、ライトファイバ１の構成材料に石英を適用することも可能であるが、プラスチックに比べると可撓性が低く、また大径化に難点があるため、車両への適用は制限されている。   In addition, although it is possible to apply quartz to the constituent material of the light fiber 1, its application to a vehicle is limited because it is less flexible than plastic and has a difficulty in increasing the diameter.

図示しない光源は、ライトファイバ１の一端から内部へ光を入れ、ライトファイバ１を任意の明るさで、かつ、任意の色で発光させるための光源装置である。例えば、出力１００Ｗのハロゲンランプ光源装置などを用いることができる。   A light source (not shown) is a light source device that enters light from one end of the light fiber 1 and causes the light fiber 1 to emit light with an arbitrary brightness and an arbitrary color. For example, a halogen lamp light source device having an output of 100 W can be used.

ファイバホルダ１は、塩化ビニールなどの弾性を有する樹脂材料から一体成形されたものである。樹脂材料は弾性を有する軟質材料に制限するものではなく、ポリプロピレンやポリエチレンなどの弾性を有しない硬質材料とすることもできる。   The fiber holder 1 is integrally formed from an elastic resin material such as vinyl chloride. The resin material is not limited to a soft material having elasticity, and may be a hard material having no elasticity such as polypropylene and polyethylene.

図２や図４にその断面形状が示されているように、ライトファイバ１の軸方向に延在する底壁５と、底壁５の両側から同一方向に立ち上がる一対の対向壁６，６とを有し、Ｕ字状断面が長手方向に連続する樋状に形成されている（図３参照）。底壁５と一対の対向壁６，６は、滑らかに繋がれており、ライトファイバ１の外表面２とファイバホルダ３の内面とが隙間無く接触するようになっている。底壁５と一対の対向壁６，６で囲まれる内側の空間は保持空間１０となっている。ライトファイバ１の非固定側部分２ｂの外表面２は、ファイバホルダ３の開口端９から露出している。   As shown in FIG. 2 and FIG. 4, the bottom wall 5 extending in the axial direction of the light fiber 1 and a pair of opposing walls 6, 6 rising in the same direction from both sides of the bottom wall 5, The U-shaped cross section is formed in a bowl shape that is continuous in the longitudinal direction (see FIG. 3). The bottom wall 5 and the pair of opposed walls 6 and 6 are smoothly connected so that the outer surface 2 of the light fiber 1 and the inner surface of the fiber holder 3 are in contact with each other without any gap. An inner space surrounded by the bottom wall 5 and the pair of opposing walls 6, 6 is a holding space 10. The outer surface 2 of the non-fixed side portion 2 b of the light fiber 1 is exposed from the open end 9 of the fiber holder 3.

一対の対向壁６，６の高さ寸法は、一対の対向壁６，６の端部がライトファイバ１より突出しないように、ライトファイバ１の直径と同程度ないしはそれより低く形成されている。底壁５及び一対の対向壁６，６の肉厚は、ファイバホルダ３の弾性や振動吸収性、ライトファイバ１とパネル１３の係合溝１４との隙間を考慮して設定されている。   The height of the pair of opposing walls 6 and 6 is formed to be the same as or lower than the diameter of the light fiber 1 so that the ends of the pair of opposing walls 6 and 6 do not protrude from the light fiber 1. The thickness of the bottom wall 5 and the pair of opposing walls 6 and 6 is set in consideration of the elasticity and vibration absorption of the fiber holder 3 and the clearance between the light fiber 1 and the engagement groove 14 of the panel 13.

一対の対向壁６，６の内面６ａでその先端側には、相互に対向する位置でライトファイバ１がファイバ保持空間１０から不用意に抜け出すのを防止する内爪（内側可撓係止部）７が、ライトファイバ１の中心軸と平行になるように条設されている。内爪７は、根元側が太く先端側が細くなっていて、根元側を支点として撓み可能になっている。内爪７の突き出し長さは任意であり、ライトファイバ１の外観を損なわず、ライトファイバ１を係止できる程度の長さに形成されている。内爪７の裏面はライトファイバ１に対する係止面７ａとして作用し、表面は傾斜形成された案内面７ｂとして作用する。   An inner claw (inner flexible locking portion) that prevents the light fiber 1 from inadvertently coming out of the fiber holding space 10 at the front end side of the inner surfaces 6a of the pair of opposing walls 6, 6 7 is provided so as to be parallel to the central axis of the light fiber 1. The inner claw 7 is thick at the base side and thin at the tip side, and can be bent with the base side as a fulcrum. The protruding length of the inner claw 7 is arbitrary, and is formed to such a length that the light fiber 1 can be locked without impairing the appearance of the light fiber 1. The back surface of the inner claw 7 acts as a locking surface 7a for the light fiber 1, and the surface acts as an inclined guide surface 7b.

ライトファイバ１の固定側部分２ａをファイバホルダ３に取り付ける際は、ライトファイバ１を案内面７ｂの幅方向に沿ってスライドさせ、内爪７を根元側を支点として内向きに撓ませ、一対の対向壁６，６を押し広げながら、ファイバホルダ３の開口端９から底壁５に当接するまでライトファイバ１を押し込んで取り付ける。図２には、ライトファイバ１の固定状態が示されている。   When attaching the fixed side portion 2a of the light fiber 1 to the fiber holder 3, the light fiber 1 is slid along the width direction of the guide surface 7b, the inner claw 7 is bent inward with the root side as a fulcrum, and a pair of The light fiber 1 is pushed in and attached from the open end 9 of the fiber holder 3 until it abuts against the bottom wall 5 while spreading the opposing walls 6 and 6. FIG. 2 shows a fixed state of the light fiber 1.

ライトファイバ１の取付後は、内爪７が元位置に弾性復元し、内爪７の係止面７ａが略水平になる。ライトファイバ１は、一対の対向壁６，６の弾性力によって狭持され、内爪７の係止面７ａによって係止され、ファイバホルダ３からの抜けが防止される。また、ライトファイバ１と内爪７は長手方向の全長に渡って線接触し、ライトファイバ１と一対の対向壁６，６及び底壁５は長手方向の全長に渡って面接触するから、ライトファイバ１の振動吸収性が向上し、がたつきが防止される。このようにして、ライトファイバ１の外表面２の一部を露出させた状態の組立体として、パネル１３の係合溝１４に固定する前の中間製品としてのファイバアッセンブリ１１が構成される。   After the light fiber 1 is attached, the inner claw 7 is elastically restored to the original position, and the locking surface 7a of the inner claw 7 becomes substantially horizontal. The light fiber 1 is pinched by the elastic force of the pair of opposing walls 6 and 6 and is locked by the locking surface 7a of the inner claw 7, so that the light fiber 1 is prevented from coming off from the fiber holder 3. The light fiber 1 and the inner claw 7 are in line contact over the entire length in the longitudinal direction, and the light fiber 1 and the pair of opposing walls 6 and 6 and the bottom wall 5 are in surface contact over the entire length in the longitudinal direction. The vibration absorbability of the fiber 1 is improved and rattling is prevented. Thus, the fiber assembly 11 as an intermediate product before being fixed to the engagement groove 14 of the panel 13 is configured as an assembly in which a part of the outer surface 2 of the light fiber 1 is exposed.

一対の対向壁６，６の外面６ｂでその根元側には、ファイバホルダ３がパネル１３の係合溝１４から抜けるのを防止する外爪（外側可撓係止部）８がライトファイバ１の中心軸と平行になるように条設されている。外爪８は、ファイバホルダ３の長手方向の全長に渡って連続形成されているため、外爪８とパネル１３の係合溝１４の内面１４ａは線接触し、係止力が高められるようになっている。   An outer claw (outer flexible locking portion) 8 for preventing the fiber holder 3 from coming out of the engaging groove 14 of the panel 13 is provided on the base side of the outer surface 6 b of the pair of opposing walls 6, 6. It is provided so as to be parallel to the central axis. Since the outer claw 8 is continuously formed over the entire length in the longitudinal direction of the fiber holder 3, the outer claw 8 and the inner surface 14a of the engagement groove 14 of the panel 13 are in line contact so that the locking force is increased. It has become.

外爪８は、根元側から先端側にかけてやや上向き（挿入反対方向）に傾斜して形成されている。また、外爪８の根元側には部分的に細い部分が形成されていて、外爪８は外向き（開き方向に）に撓み易くなっている。外爪８の先端は、係合溝１４内面１４ａとの接触面積が大きくなるように、丸く形成されている。このため、パネル１３の係合溝１４から抜け出す方向でファイバホルダ３に力が作用すると、外爪８の先端と係合溝１４の内面１４ａとの摩擦力によって外爪８が抜けを妨げる方向に変形する。したがって、係合溝１４からのファイバホルダ３の不用意な抜けを確実に防止することができる。   The outer claw 8 is formed to be inclined slightly upward (in the direction opposite to the insertion direction) from the base side to the tip side. Moreover, the thin part is partially formed in the base side of the outer nail | claw 8, and the outer nail | claw 8 is easy to bend outward (in an opening direction). The tip of the outer claw 8 is formed in a round shape so that the contact area with the inner surface 14a of the engagement groove 14 is increased. For this reason, when a force acts on the fiber holder 3 in the direction in which the panel 13 is pulled out from the engaging groove 14, the outer claw 8 is prevented from being pulled out by the frictional force between the tip of the outer claw 8 and the inner surface 14 a of the engaging groove 14. Deform. Therefore, inadvertent removal of the fiber holder 3 from the engaging groove 14 can be reliably prevented.

ライトファイバ１が固定される被取付体としてのパネル１３は、ライトファイバ１が自動車に適用される場合には、図５に示されるように、主として車室内のインストルメントパネル１５やドアパネル１６などであり、ライトファイバ１が建物に適用される場合には、内壁や外壁に取り付けられるパネルボードなどである。上述したように、ライトファイバ１が可撓性を有し、任意の方向に湾曲させて用いることができるため、ライトファイバ１を固定するパネル１３は、平面的なものに限られず、３次元的に湾曲したものであってもよい。   When the light fiber 1 is applied to an automobile, the panel 13 as the mounted body to which the light fiber 1 is fixed is mainly an instrument panel 15 or a door panel 16 in the vehicle interior as shown in FIG. Yes, when the light fiber 1 is applied to a building, it is a panel board or the like attached to an inner wall or an outer wall. As described above, since the light fiber 1 has flexibility and can be used by being bent in an arbitrary direction, the panel 13 for fixing the light fiber 1 is not limited to a planar one, but is three-dimensional. It may be curved.

パネル１３には、例えば、ポリプロピレン（ＰＰ）やポリエチレン（ＰＥ）などの樹脂材料から成形されたものが用いられる。パネル１３面には、ライトファイバ１の所定の配索経路を形成する係合溝１４が凹設されている。係合溝１４の断面形状はファイバホルダ３との関係によって決定されるものであり、本実施形態ではＵ字状に形成されている（図２参照）。溝深さは、ライトファイバ１が多少出っ張っても構わないが、本実施形態では係合溝１４からライトファイバ１が出っ張らない寸法に形成されている。溝幅は、ライトファイバ１の直径とファイバホルダ３の厚みとの関係で決定される。すなわち、ファイバアッセンブリ１１が係合溝１４に固定された際に、係合溝１４とファイバアッセンブリ１１とが接触し、ライトファイバ１がファイバホルダ３によって狭持される寸法に設定されている。   The panel 13 is made of, for example, a resin material such as polypropylene (PP) or polyethylene (PE). On the surface of the panel 13, an engagement groove 14 that forms a predetermined routing path of the light fiber 1 is recessed. The cross-sectional shape of the engagement groove 14 is determined by the relationship with the fiber holder 3 and is formed in a U shape in this embodiment (see FIG. 2). The groove depth may be such that the light fiber 1 protrudes to some extent, but in this embodiment, the groove is formed to have a dimension such that the light fiber 1 does not protrude from the engagement groove 14. The groove width is determined by the relationship between the diameter of the light fiber 1 and the thickness of the fiber holder 3. That is, when the fiber assembly 11 is fixed to the engagement groove 14, the engagement groove 14 and the fiber assembly 11 are in contact with each other, and the light fiber 1 is set to a size that is held by the fiber holder 3.

ライトファイバ１の非固定側部分２ｂの外表面２が露出するようにして、ライトファイバ１をファイバホルダ３を介してパネル１３に取り付けると、取り付けの際に内向きに撓んだ一対の対向壁６，６が外向きに弾性復元しようとする弾性力が、係合溝１４の内面１４ａとファイバホルダ３の外面６ｂとの接触面に面圧力として働き、ファイバホルダ３ないしはファイバアッセンブリ１１が係合溝１４に固定される。   When the light fiber 1 is attached to the panel 13 via the fiber holder 3 so that the outer surface 2 of the non-fixed side portion 2b of the light fiber 1 is exposed, a pair of opposing walls that are bent inward during attachment The elastic force 6 and 6 attempt to elastically recover outward acts as a surface pressure on the contact surface between the inner surface 14a of the engagement groove 14 and the outer surface 6b of the fiber holder 3, and the fiber holder 3 or the fiber assembly 11 is engaged. It is fixed to the groove 14.

図５には、ライトファイバ１の自動車への適用例が示されている。ライトファイバ１は、車室内のインストルメントパネル１５と、ドアパネル１６と、コンソールボックス１７に取り付けられている。図示しないが、ライトファイバ１を、カーテシーランプやマップランプやルームランプや外装用途として用いることも可能である。   FIG. 5 shows an application example of the light fiber 1 to an automobile. The light fiber 1 is attached to an instrument panel 15, a door panel 16, and a console box 17 in the vehicle interior. Although not shown, the light fiber 1 can also be used as a courtesy lamp, a map lamp, a room lamp, or an exterior application.

以上のように、本実施形態の線条体固定構造によれば、ライトファイバ１がファイバホルダ３を介してパネル１３に固定されるから、ライトファイバ１の非固定側部分２ｂである外表面２をパネル１３の係合溝１４の開口端をから一様に露出させることができ、照明の光むらやライトファイバ１の美観を損なうことを防止することができる。ライトファイバ１がパネル１３から出っ張らないから、ライトファイバ１と他部品との干渉を回避することができる。弾性を有するファイバホルダ３を用いることによって、ライトファイバ１をがたつきなく固定でき、ライトファイバ１の傷や破損などの損傷を防止することができる。   As described above, according to the linear body fixing structure of the present embodiment, since the light fiber 1 is fixed to the panel 13 via the fiber holder 3, the outer surface 2 that is the non-fixed side portion 2 b of the light fiber 1. Can be uniformly exposed from the opening end of the engaging groove 14 of the panel 13, and it is possible to prevent the light unevenness of illumination and the appearance of the light fiber 1 from being impaired. Since the light fiber 1 does not protrude from the panel 13, interference between the light fiber 1 and other components can be avoided. By using the fiber holder 3 having elasticity, the light fiber 1 can be fixed without rattling, and damage such as scratches and breakage of the light fiber 1 can be prevented.

また、本実施形態のファイバホルダ３は、樋状断面で長手方向に連続して形成されているから、ライトファイバ１の固定側部分２ａの外表面２全体を軸方向と円周方向の両方向で連続して拘束することができると共に、ライトファイバ１の非固定側部分２ｂの外表面２をこのファイバホルダ３から一様に露出させることができる。ファイバホルダ３の一対の対向壁６，６の内面６ａと外面６ｂとには、それぞれ内爪７と外爪８とが条設されているから、ファイバホルダ３からのライトファイバ１の抜けを確実に防止することができると共に、パネル１３の係合溝１４からのファイバホルダ３の抜けを防止することができる。   Further, since the fiber holder 3 of the present embodiment is continuously formed in the longitudinal direction with a bowl-shaped cross section, the entire outer surface 2 of the fixed-side portion 2a of the light fiber 1 is both axially and circumferentially. The outer surface 2 of the non-fixed side portion 2b of the light fiber 1 can be uniformly exposed from the fiber holder 3 while being able to be constrained continuously. Since the inner claw 7 and the outer claw 8 are provided on the inner surface 6a and the outer surface 6b of the pair of opposing walls 6 and 6 of the fiber holder 3, respectively, the light fiber 1 can be securely removed from the fiber holder 3. The fiber holder 3 can be prevented from coming off from the engagement groove 14 of the panel 13.

また、ファイバホルダ３を用いたライトファイバ１の固定方法によれば、ライトファイバ１の無垢の硬質面をファイバホルダ３で保護した状態で、パネル１３に固定することができるため、ライトファイバ１の取り付け時の傷や損傷を防止でき、取付性やメンテナンス性を向上することもできる。   Further, according to the fixing method of the light fiber 1 using the fiber holder 3, the solid hard surface of the light fiber 1 can be fixed to the panel 13 while being protected by the fiber holder 3. Scratches and damage during mounting can be prevented, and mounting and maintenance can be improved.
