Description

本発明は、車両用ドアのドアパネルの上縁に沿って装着され、ドアパネルと窓板（サイドウインドゥガラス）との間をシールするためのベルトモールに関する。 The present invention relates to a belt molding that is mounted along an upper edge of a door panel of a vehicle door and seals between the door panel and a window plate (side window glass).

一般にベルトモールは、金属製の芯材に合成樹脂製のリップ等を接合一体化して構成される。ベルトモールでは、金属製芯材の表面の一部を意図的に露出させて、この露出面を金属的な外観を呈する意匠面として活用する設計も多く採用されている。また、ベルトモールのドアパネル上縁への装着時に、ベルトモールの末端部が車体の一部（例えば、ドア窓枠を構成するガーニッシュ）に干渉するのを避けるために、ベルトモールの末端部領域を一部切り欠き形成する設計も採用されており、その場合には、この切り欠き部位（欠損部）を覆うための「エンドキャップ」と呼ばれる被覆材を装着することも行われている。つまり、ベルトモールの一類型として、長尺なベルトモール本体と、ベルトモール本体の末端部領域に装着されるエンドキャップとからなるものが知られている。 In general, a belt molding is configured by joining and integrating a synthetic resin lip or the like with a metal core. In the belt molding, many designs are employed in which a part of the surface of the metal core material is intentionally exposed and the exposed surface is used as a design surface having a metallic appearance. In addition, when the belt molding is attached to the upper edge of the door panel, the belt molding end region is set to prevent the belt molding end from interfering with a part of the vehicle body (for example, garnish constituting the door window frame). A design in which a part of the cutout is formed is also employed, and in that case, a covering material called an “end cap” for covering the cutout portion (defect portion) is also mounted. That is, one type of belt molding is known that is composed of a long belt molding main body and an end cap that is attached to the end region of the belt molding main body.

ちなみに、ベルトモール本体をインサートとしてエンドキャップを射出成形で一体成形しようとする試みもある。但し、ベルトモール本体（特に芯材）が金属製であると、当該金属製のインサートが射出成形型（金型）内で滑りを生じ、金型内の所定位置にベルトモール本体を正しくセットできなかったり、金属製のベルトモール本体に樹脂製のエンドキャップが十分に接合しなかったりといった不具合が生じることがある。このため、ベルトモール本体とエンドキャップを別体とすることが通例となっている。 Incidentally, there is an attempt to integrally mold the end cap by injection molding with the belt molding body as an insert. However, if the belt molding body (especially the core material) is made of metal, the metal insert slips in the injection mold (mold), and the belt molding body can be correctly set in a predetermined position in the mold. Or a resin end cap may not be sufficiently bonded to the metal belt molding body. For this reason, it is customary to separate the belt molding body and the end cap.

そして、エンドキャップは一般に、ベルトモールを車体（ドアパネル）に装着するためのクリップ片や、ベルトモールの上記切り欠き部位（欠損部）を覆うための被せ部を備えており、形状が複雑になり易い。このため、射出成形によってエンドキャップを一体物（単一品）として製造しようとすると、成形型の構造の複雑化や成形型の開閉性の確保といった困難な問題に直面する。それ故、エンドキャップを最初から一体物として成形することを断念する代わりに、基体（又は基部）と蓋体のツーピースに分け、それぞれを個別に射出成形した後に組み合わせるという設計手法が提案されている。 The end cap generally includes a clip piece for attaching the belt molding to the vehicle body (door panel) and a covering portion for covering the cutout portion (defect portion) of the belt molding, which makes the shape complicated. easy. For this reason, when it is going to manufacture an end cap as a one-piece | unit (single article) by injection molding, it faces difficult problems, such as complication of the structure of a shaping | molding die and ensuring of the openability of a shaping | molding die. Therefore, instead of giving up forming the end cap as a single piece from the beginning, a design method has been proposed in which the base (or base) and the lid are divided into two pieces, which are individually injection molded and then combined. .

特許文献１は、そのようなツーピース型エンドキャップの先行例を示す。特許文献１の段落００１８によると、合成樹脂製のクリップ体（エンドキャップ）１は、基部１１と、基部１１から突設されたクリップ片１２と、基部１１及びクリップ片１２とは別体に構成された蓋体１４とから成っている。そして同文献の段落００２２によれば、基部１１をモール本体５内に挿入すると共に、蓋体１４をモール本体の端部５ａに嵌着した後で、所与のカシメ片を折り曲げて、蓋体１４及び基部１１の各対応部位に設けられているカシメ受部に圧接することにより、蓋体１４と基部１１（及び基部１１と一体のクリップ片１２）がモール本体５に固定される。 Patent document 1 shows the prior example of such a two-piece type end cap. According to paragraph 0018 of Patent Document 1, a synthetic resin clip body (end cap) 1 is composed of a base 11, a clip piece 12 projecting from the base 11, and the base 11 and the clip piece 12. The lid 14 is made up of. According to paragraph 0022 of the same document, the base 11 is inserted into the molding body 5 and the lid 14 is fitted to the end 5a of the molding body, and then a given caulking piece is bent to form the lid. The lid body 14 and the base portion 11 (and the clip piece 12 integral with the base portion 11) are fixed to the molding body 5 by press-contacting the caulking receiving portions provided at the corresponding portions of the base portion 11 and the base portion 11.

特開２０１１−２４５９５９号公報JP 2011-245959 A

しかしながら、特許文献１のクリップ体（エンドキャップ）１は、基部１１と蓋体１４との相対配置関係を確定的又は固定的に保持する構造を持っていないため、基部１１及び蓋体１４をそれぞれモール本体５にカシメ（加締め）る際に、それぞれの固定位置が僅かにずれることがある。つまり、蓋体１４と、基部１１と一体化したクリップ片１２との間の寸法（又は相対配置）にバラつきが生じ、モールをクリップ片１２で車体に取り付けたときに、モールの端部位置（即ち、蓋体１４の位置）にバラつきが生じてしまう。その結果、蓋体１４と基部１１との間に無視し得ない大きさの隙間が発生し、見栄えが悪くなってしまうことがある。 However, since the clip body (end cap) 1 of Patent Document 1 does not have a structure that holds the relative positional relationship between the base portion 11 and the lid body 14 deterministically or fixedly, the base portion 11 and the lid body 14 are respectively attached. When caulking (caulking) the molding body 5, the respective fixing positions may be slightly shifted. That is, the dimension (or relative arrangement) between the lid body 14 and the clip piece 12 integrated with the base portion 11 varies, and when the molding is attached to the vehicle body with the clip piece 12, the end position ( In other words, the lid 14 has a variation in position). As a result, a gap having a size that cannot be ignored is generated between the lid body 14 and the base portion 11, and the appearance may deteriorate.

本発明の目的は、基体および蓋体からなるツーピース型エンドキャップを備えたベルトモールにおいて、エンドキャップの基体と蓋体との相対配置関係を確定的又は固定的に保持することで、基体および蓋体が互いに位置ズレすることなくエンドキャップをベルトモール本体に対して取り付け可能なベルトモールを提供することにある。 An object of the present invention is to provide a belt molding having a two-piece type end cap comprising a base body and a lid body, by deterministically or securely holding the relative arrangement relationship between the base body and the lid body of the end cap, thereby An object of the present invention is to provide a belt molding capable of attaching an end cap to a belt molding main body without causing the bodies to be displaced from each other.

図３（及び図４）の断面図に示すように、ベルトモール本体７は、金属製の芯材１１と、その芯材１１の外表面及び内表面の一部に押出成形によって接合された樹脂製のリップ等（１５ａ〜１５ｆ）とを備えてなる異材複合体である。なお、図３及び図４に示す芯材１１は断面であるが、線の錯綜による見難さを回避するため敢えてハッチングを付与していない。 As shown in the cross-sectional view of FIG. 3 (and FIG. 4), the belt molding body 7 includes a metal core 11 and a resin bonded to the outer surface and a part of the inner surface of the core 11 by extrusion molding. It is a dissimilar material composite provided with manufactured lips and the like (15a to 15f). The core material 11 shown in FIGS. 3 and 4 has a cross section, but is not provided with hatching in order to avoid difficulty in viewing due to the complexity of the lines.

図３に示すように、金属製の芯材１１は、互いに対向する車内側側壁部１２および車外側側壁部１３、並びに、これら両側壁部１２，１３をそれらの頂部で一体に連結する頂壁部１４を有しており、車内側側壁部１２、頂壁部１４および車外側側壁部１３によって上に凸で下に凹の横断面形状をなしている。芯材１１の一部表面（例えば図３の頂壁部１４の外面や車外側側壁部１３の外面）は、その金属地肌が露出されてベルトモールの外観を向上させる装飾面として利用されている。なお、芯材１１を構成する金属は、好ましくはステンレス鋼であるが、これに代えてアルミニウム等の他の金属を使用してもよい。 As shown in FIG. 3, the metal core 11 includes a vehicle interior side wall portion 12 and a vehicle exterior side wall portion 13 that face each other, and a top wall that integrally connects these side wall portions 12 and 13 at their top portions. The vehicle interior side wall portion 12, the top wall portion 14, and the vehicle exterior side wall portion 13 form a cross section that is convex upward and concave downward. A part of the surface of the core material 11 (for example, the outer surface of the top wall portion 14 or the outer surface of the vehicle outer side wall portion 13 in FIG. 3) is used as a decorative surface that exposes the metal background and improves the appearance of the belt molding. . The metal constituting the core member 11 is preferably stainless steel, but other metals such as aluminum may be used instead.

ベルトモール本体７の芯材の車内側側壁部１２の表面は概ね樹脂１５で被覆され、その車内側側壁部１２の表面には、同じ樹脂製の上側リップ１５ａ、車内側リップ１５ｂおよび第１の下部係合部１５ｃが設けられている。また、芯材の車外側側壁部１３の内側面には、同じ樹脂製の保持リップ１５ｄ、第２の下部係合部１５ｅおよび車外側リップ１５ｆが設けられている。上側リップ１５ａおよび車内側リップ１５ｂは、窓板５との間に生じた隙間をシールして雨水や埃が車室内およびドアパネル２内に浸入するのを防止する。また、第１の下部係合部１５ｃ、保持リップ１５ｄ、第２の下部係合部１５ｅおよび車外側リップ１５ｆは、ベルトモール本体７をドアパネル２の上縁に保持・固定するための係合部位である。なお、芯材１１に接合される樹脂は、好ましくはオレフィン系熱可塑性エラストマーであるが、芯材１１に接合されるリップ等（１５ａ〜１５ｆ）は弾性変形可能な材料で成形されていればよく、他の種類の熱可塑性エラストマー（例えばスチレン系熱可塑性エラストマー）、軟質ポリ塩化ビニル又はゴム等で代替されてもよい。 The surface of the inner side wall portion 12 of the core material of the belt molding body 7 is generally covered with a resin 15, and the upper side lip 15 a, the inner side lip 15 b and the first lip 15 b made of the same resin are formed on the surface of the inner side wall portion 12. A lower engaging portion 15c is provided. Further, the same resin-made holding lip 15d, second lower engaging portion 15e, and vehicle outer lip 15f are provided on the inner surface of the vehicle outer side wall portion 13 of the core material. The upper lip 15a and the vehicle inner lip 15b seal a gap formed between the window plate 5 and prevent rainwater and dust from entering the vehicle interior and the door panel 2. The first lower engagement portion 15c, the holding lip 15d, the second lower engagement portion 15e, and the vehicle outer lip 15f are engagement portions for holding and fixing the belt molding body 7 to the upper edge of the door panel 2. It is. The resin bonded to the core material 11 is preferably an olefin-based thermoplastic elastomer, but the lips and the like (15a to 15f) bonded to the core material 11 may be formed of an elastically deformable material. Other types of thermoplastic elastomers (for example, styrenic thermoplastic elastomers), soft polyvinyl chloride or rubber may be substituted.

ベルトモール本体７は、その長手方向全体にわたって一様な横断面形状を有しているわけではなく、その後端部領域において、エンドキャップ８が取り付けられる欠損部１６を有している（図８（Ｂ）参照）。図８（Ｂ）からわかるように、欠損部１６においては、ベルトモール本体７を構成する前記三つの壁部（１２，１３，１４）の一部を切り欠いて、より具体的には頂壁部１４の一部と車内側側壁部１２とを取り除くように切り欠いて形成されており、その結果、当該欠損部１６は、車外側側壁部１３と、それに繋がった頂壁部１４の一部分だけを残して構成されている。ベルトモール本体７の端部領域にこのような欠損部１６を設定することで、ベルトモール本体７の末端部が、ドアパネル２に立設されたガーニッシュ４と干渉する事態を回避できる。但し、この欠損部１６を切り欠いたままの状態にしておくと、切り欠いた部分のバリや変形などが露出し、外観の悪化や接触時の危険を招くため、この欠損部１６に対してはエンドキャップ８が取り付けられる。 The belt molding body 7 does not have a uniform cross-sectional shape over the entire longitudinal direction thereof, but has a defect portion 16 to which the end cap 8 is attached in the rear end region (FIG. 8 ( B)). As can be seen from FIG. 8 (B), in the missing part 16, a part of the three wall parts (12, 13, 14) constituting the belt molding body 7 is notched, and more specifically, the top wall. The part 14 and the vehicle interior side wall part 12 are cut out so as to be removed. As a result, the defect part 16 is formed only in the vehicle outer side wall part 13 and a part of the top wall part 14 connected thereto. It is configured to leave. By setting such a missing portion 16 in the end region of the belt molding body 7, it is possible to avoid a situation in which the end portion of the belt molding body 7 interferes with the garnish 4 erected on the door panel 2. However, if the defect portion 16 is left in a notched state, burrs and deformations of the notched portion are exposed, resulting in deterioration of the appearance and danger at the time of contact. The end cap 8 is attached.

［エンドキャップ］
図８（Ａ）に示すように、本実施形態のエンドキャップ８は、基体２０と蓋体３０とからなり、それらは別部品として個別に射出成形されたものである。なお、基体２０および蓋体３０を構成する樹脂は、好ましくはポリブチレンテレフタレート（ＰＢＴ）であるが、これに代えて、ポリプロピレン（ＰＰ）、ポリアセタール（ＰＯＭ）、ポリアミド（ＰＡ）、ポリフェニレンスルフィド（ＰＰＳ）、ポリエーテルエーテルケトン（ＰＥＥＫ）等の熱可塑性樹脂を使用してもよい。 [end cap]
As shown in FIG. 8A, the end cap 8 of this embodiment includes a base body 20 and a lid body 30, which are individually injection-molded as separate parts. The resin constituting the substrate 20 and the lid 30 is preferably polybutylene terephthalate (PBT), but instead of this, polypropylene (PP), polyacetal (POM), polyamide (PA), polyphenylene sulfide (PPS). ), Or a thermoplastic resin such as polyetheretherketone (PEEK).

［エンドキャップの基体］
図２，図５および図８（Ａ），（Ｂ）に示すように、エンドキャップの基体２０は、ベルトモールの長手方向に延びる長板状の基体本体部２１を有している。基体本体部２１は、基体２０のほぼ全長にわたって延設された被せ部２２を有し、この被せ部２２は、ベルトモール本体の欠損部１６の上方を覆うべく基体２０の上縁に沿って延び且つ車外側に向けて突出するように形成されている。また図５に示すように、基体本体部２１の蓋体側端部の近傍には、被せ部２２の真下に位置する片持ち梁形状の棒状部２３と、その棒状部２３の蓋体側端部の下方に位置する規制凸部２５とが設けられている。 [End cap substrate]
As shown in FIGS. 2, 5, and 8A and 8B, the base 20 of the end cap has a long plate-like base body 21 extending in the longitudinal direction of the belt molding. The base body portion 21 has a covering portion 22 extending over almost the entire length of the base body 20, and the covering portion 22 extends along the upper edge of the base body 20 so as to cover the upper portion of the defect portion 16 of the belt molding body. And it is formed so that it may protrude toward the vehicle outer side. Further, as shown in FIG. 5, in the vicinity of the lid-side end portion of the base body portion 21, a cantilever-shaped rod-shaped portion 23 positioned directly below the covering portion 22, and the lid-side end portion of the rod-shaped portion 23. A regulating convex portion 25 located below is provided.

片持ち梁形状の棒状部２３は、被せ部２２の真下に位置してベルトモールの長手方向に沿って延びている。ここで「片持ち梁形状」とは、棒状部２３が、その直下にある短い隙間Ｓ（図５）を間に挟んで基体本体部２１から部分的に分離された状態にあることを表現している。棒状部２３がこのような片持ち梁形状をなしていることで、棒状部２３の先端部（蓋体側端部）付近は、多少の弾性変形が可能な自由端又は弾性端となっている。そして、この片持ち梁形状の棒状部２３の先端には、凸状の基体係止部２４が形成されている。この基体係止部２４は、後述する蓋体３０の一部（突起部３３）と係合して、基体装着時の蓋体３０が基体２０から離脱するのを防止する。 The cantilever-shaped rod-shaped portion 23 is located directly below the covering portion 22 and extends along the longitudinal direction of the belt molding. Here, the “cantilever shape” represents that the rod-like portion 23 is partially separated from the base body portion 21 with a short gap S (FIG. 5) immediately below it interposed therebetween. ing. Since the rod-like portion 23 has such a cantilever shape, the vicinity of the tip portion (end portion on the lid side) of the rod-like portion 23 is a free end or an elastic end capable of some elastic deformation. A convex base locking portion 24 is formed at the tip of the cantilever-shaped rod-shaped portion 23. The base locking portion 24 engages with a part of the lid 30 (projection 33) described later to prevent the lid 30 from being detached from the base 20 when the base is mounted.

図５に示すように、規制凸部２５は、基体本体部２１の蓋体側末端位置にあって、基体本体部２１から車外側に向けて突出した概略六面体状のブロック体として形成されている。この規制凸部２５は、上面２５ａ、下面２５ｂ、末端側側面２５ｃ、中央側側面２５ｄ（末端側側面２５ｃの反対面）、車外側端面２５ｅ、更には、この車外側端面よりも低い位置で且つ車内側寄りの奥まった位置にある段差部端面２５ｆを有している。これら複数の面が、後ほど説明するような蓋体３０との相互当接関係に基づいて基体２０に対する蓋体３０の一義的な位置決めに関与する。より具体的には、上面２５ａおよび下面２５ｂは、それぞれ上側規制部および下側規制部として基体２０に対する蓋体３０の上下方向位置決めに関与する。また、末端側側面２５ｃおよび中央側側面２５ｄは、それぞれ末端側規制部および中央側規制部として基体２０に対する蓋体３０の長手方向位置決めに関与する。更に、車外側端面２５ｅおよび段差部端面２５ｆは、基体２０に対する蓋体３０の車内外方向位置決めに部分的に関与する。 As shown in FIG. 5, the restriction convex portion 25 is formed as a substantially hexahedral block body that protrudes from the base body portion 21 toward the vehicle outer side at the lid body side end position of the base body portion 21. The restricting convex portion 25 has an upper surface 25a, a lower surface 25b, a terminal side surface 25c, a center side surface 25d (a surface opposite to the terminal side surface 25c), a vehicle outer end surface 25e, and a position lower than the vehicle outer end surface. It has a stepped portion end face 25f located at a deep position on the inner side of the vehicle. The plurality of surfaces are involved in the unique positioning of the lid body 30 with respect to the base body 20 based on the mutual contact relationship with the lid body 30 as will be described later. More specifically, the upper surface 25a and the lower surface 25b are involved in the vertical positioning of the lid 30 with respect to the base body 20 as an upper restricting portion and a lower restricting portion, respectively. Further, the end side surface 25c and the center side surface 25d are involved in positioning in the longitudinal direction of the lid body 30 with respect to the base body 20 as a terminal side restricting portion and a center side restricting portion, respectively. Furthermore, the vehicle outer end surface 25e and the stepped portion end surface 25f are partly involved in the positioning of the lid 30 with respect to the base body 20 in the vehicle interior / exterior direction.

図８に示すように、基体本体部２１には、その車内側の側面においてクリップ片２６が設けられている。ドアパネル２には、当該クリップ片２６に対応するクリップ止め部（図示略）が設けられており、このクリップ止め部にクリップ片２６を係合させることで、ベルトモール６がドアパネル２に取り付けられる。 As shown in FIG. 8, the base body 21 is provided with a clip piece 26 on the side surface on the vehicle inner side. The door panel 2 is provided with a clip stopper (not shown) corresponding to the clip piece 26, and the belt molding 6 is attached to the door panel 2 by engaging the clip piece 26 with the clip stopper.

なお、図６は、図５の矢印Ａ方向から見た説明用の概略側面図である。図６に示すように、被せ部２２の車外側に向けた突出方向（破線Ｌ１で示す）と規制凸部２５の車外側に向けた突設方向（破線Ｌ２で示す）が、基体２０を射出成形する場合に使用する成形型の脱型方向と略平行となるように、両部（２２，２５）が設計されている。この設計によれば、ここで説明したような複雑な形状の基体２０を射出成形で製造することが容易になる。なお、図６中の二点鎖線Ｐは、成形型のパーティングラインを示す。 6 is a schematic side view for explanation as viewed from the direction of arrow A in FIG. As shown in FIG. 6, the projecting direction of the cover portion 22 toward the vehicle outer side (shown by a broken line L1) and the projecting direction of the restricting convex portion 25 toward the vehicle outer side (shown by a broken line L2) inject the base body 20. Both parts (22, 25) are designed so as to be substantially parallel to the mold releasing direction of the mold used for molding. According to this design, it becomes easy to manufacture the base body 20 having a complicated shape as described here by injection molding. In addition, the dashed-two dotted line P in FIG. 6 shows the parting line of a shaping | molding die.

［エンドキャップの蓋体］
図４，図５，図７および図８（Ａ）に示すように、エンドキャップの蓋体３０は、ベルトモール本体７の端面を覆うための蓋体本体部３１を有している。更に蓋体本体部３１には、覆い部３２、突起部３３および取付部３４が設けられている。なお、突起部３３は、蓋体係止部として機能する。 [End cap lid]
As shown in FIG. 4, FIG. 5, FIG. 7 and FIG. 8A, the end cap lid 30 has a lid body 31 for covering the end surface of the belt molding body 7. Further, the lid body portion 31 is provided with a cover portion 32, a projection portion 33, and an attachment portion 34. The protrusion 33 functions as a lid locking portion.

図４および図５に示すように、覆い部３２は、蓋体本体部３１の外側縁（上側及び車外側の縁）に位置してベルトモール本体７の端面の外周縁位置を覆うための縦長な帯状部である。この覆い部３２の縦長帯状の外周面は、ベルトモール本体７の芯材の車外側側壁部１３および頂壁部１４の外面と共にベルトモールの装飾面を構成する。他方、突起部３３は、蓋体本体部３１の上端の車内側寄り位置に設けられた係合部位（蓋体係止部）であり、基体本体部２１の基体係止部２４と係合して基体装着時の蓋体３０が基体２０から離脱するのを防止する。 As shown in FIGS. 4 and 5, the cover portion 32 is positioned vertically on the outer edge (upper side and outer edge of the vehicle) of the lid body portion 31 to cover the outer peripheral edge position of the end surface of the belt molding body 7. This is a strip-shaped part. The longitudinal strip-shaped outer peripheral surface of the cover portion 32 constitutes a decorative surface of the belt molding together with the outer surface of the outer side wall portion 13 and the top wall portion 14 of the core material of the belt molding main body 7. On the other hand, the projecting portion 33 is an engaging portion (lid body locking portion) provided at a position closer to the vehicle inner side of the upper end of the lid body portion 31 and engages with the base body locking portion 24 of the base body portion 21. This prevents the lid 30 from being detached from the substrate 20 when the substrate is mounted.

取付部３４は、蓋体本体部３１の基体本体部２１との対向面側において、蓋体本体部３１から基体本体部２１に向けて突設された凸部である。取付部３４には、車内側に向けて開口した規制凹部３５が設けられている。規制凹部３５は、基体の規制凸部２５を収容可能であると共に、当該規制凹部３５の内壁部が規制凸部２５の上面２５ａ、下面２５ｂ、末端側側面２５ｃおよび中央側側面２５ｄと当接可能であるように形成されている。具体的には図７に示すように、規制凹部３５の内壁部には、規制凸部の上面２５ａに対応する内壁上面３５ａ、規制凸部の下面２５ｂに対応する内壁下面３５ｂ、規制凸部の末端側側面２５ｃに対応する内壁末端側側面３５ｃ、規制凸部の中央側側面２５ｄに対応する内壁中央側側面３５ｄが形成されている。また、規制凹部３５の奥には、奥底面３５ｅが形成されている。かくして本実施形態では、基体の規制凸部２５と蓋体の規制凹部３５とが相互に嵌合可能となっている。 The attachment portion 34 is a convex portion protruding from the lid body portion 31 toward the base body portion 21 on the side of the lid body portion 31 facing the base body portion 21. The attachment portion 34 is provided with a regulation recess 35 that opens toward the vehicle interior side. The restricting recess 35 can accommodate the restricting convex portion 25 of the base body, and the inner wall portion of the restricting recessed portion 35 can come into contact with the upper surface 25a, the lower surface 25b, the distal side surface 25c and the central side surface 25d of the restricting convex portion 25. It is formed to be. Specifically, as shown in FIG. 7, the inner wall portion of the restriction concave portion 35 includes an inner wall upper surface 35 a corresponding to the upper surface 25 a of the restriction convex portion, an inner wall lower surface 35 b corresponding to the lower surface 25 b of the restriction convex portion, and a restriction convex portion. An inner wall end side surface 35c corresponding to the end side surface 25c and an inner wall center side surface 35d corresponding to the center side surface 25d of the restricting convex portion are formed. Further, a back bottom surface 35 e is formed in the back of the regulation recess 35. Thus, in the present embodiment, the restriction convex portion 25 of the base body and the restriction concave portion 35 of the lid can be fitted to each other.

［実施形態の作用および効果］
本実施形態のベルトモールは図８（Ａ），（Ｂ）のような手順で組み立てられる。
先ず、エンドキャップの基体２０の端部に蓋体３０を取り付けることでエンドキャップ８が組み立てられる。具体的には、図５および図８（Ａ）に示すように、基体２０の規制凸部２５に対し蓋体３０の取付部３４の規制凹部３５を嵌合させるべく、規制凹部３５内に規制凸部２５を挿入させる。 [Operation and Effect of Embodiment]
The belt molding of this embodiment is assembled in the procedure as shown in FIGS.
First, the end cap 8 is assembled by attaching the lid 30 to the end portion of the base 20 of the end cap. Specifically, as shown in FIG. 5 and FIG. 8A, the restriction recess 35 of the mounting portion 34 of the lid 30 is fitted into the restriction recess 35 of the base body 20 so that the restriction recess 35 of the base body 20 is fitted. The convex part 25 is inserted.

規制凸部２５を規制凹部３５に挿入すべく蓋体３０を基体２０に接近させる過程で、蓋体の突起部３３が基体係止部２４を乗り越えて当該基体係止部２４と係合する（図４参照）。この係合により、蓋体３０が基体２０から離脱することが阻止される。突起部３３と基体係止部２４との係合完了とほぼ同時に、図４に示すように、規制凸部の車外側端面２５ｅが規制凹部の奥底面３５ｅに当接すると共に、規制凸部の段差部端面２５ｆが、規制凹部３５の下側を区画形成する規制凹部下側壁部３６（図７参照）に当接する。車外側端面２５ｅと奥底面３５ｅとの当接、及び、段差部端面２５ｆと規制凹部下側壁部３６との当接によって、基体２０に対する蓋体３０の車内側への移動（相対変位）が規制される。その一方で、蓋体係止部としての突起部３３と基体係止部２４との相互係合によって、基体２０に対する蓋体３０の車外側への移動（相対変位）が規制される。 In the process of bringing the lid 30 close to the base body 20 so as to insert the regulating convex part 25 into the regulating concave part 35, the projection 33 of the lid gets over the base locking part 24 and engages with the base locking part 24 ( (See FIG. 4). This engagement prevents the lid 30 from being detached from the base body 20. Almost simultaneously with the completion of the engagement between the protrusion 33 and the base locking portion 24, as shown in FIG. 4, the vehicle outer end surface 25e of the restricting convex portion comes into contact with the back bottom surface 35e of the restricting concave portion, and the step of the restricting convex portion. The part end face 25f abuts on a regulating recess lower side wall portion 36 (see FIG. 7) that defines and forms the lower side of the regulating recess 35. The movement (relative displacement) of the lid 30 toward the vehicle inner side with respect to the base body 20 is restricted by the contact between the vehicle outer end surface 25e and the back bottom surface 35e and the contact between the stepped portion end surface 25f and the restriction recessed lower wall portion 36. Is done. On the other hand, the movement (relative displacement) of the lid 30 to the vehicle outer side with respect to the base 20 is restricted by the mutual engagement of the protrusion 33 as the lid locking portion and the base locking portion 24.

また、突起部３３と基体係止部２４の係合完了とほぼ同時に、基体の規制凸部２５と蓋体の規制凹部３５との嵌合も完了する。規制凸部２５が規制凹部３５に嵌合した状態では、規制凸部２５の４つの面（２５ａ〜２５ｄ）が規制凹部３５の４つの内壁面（３５ａ〜３５ｄ）にそれぞれ当接する。即ち、規制凸部の上面２５ａおよび下面２５ｂが規制凹部の内壁上面３５ａおよび内壁下面３５ｂにそれぞれ当接する。この上下の当接関係に基づいて、基体２０に対する蓋体３０の上下方向移動が規制される。また、規制凸部の末端側側面２５ｃおよび中央側側面２５ｄが規制凹部の内壁末端側側面３５ｃおよび内壁中央側側面３５ｄにそれぞれ当接する。この前後（図５）の当接関係に基づいて、基体２０に対する蓋体３０の前後方向移動（長手方向移動）が規制される。このように、基体の規制凸部２５と蓋体の規制凹部３５とを嵌合させることで、基体２０と蓋体３０とを強固に相互固定することができる。 In addition, the fitting of the restricting convex portion 25 of the base and the restricting concave portion 35 of the lid is completed almost simultaneously with the completion of the engagement between the protrusion 33 and the base engaging portion 24. In a state in which the restriction convex portion 25 is fitted in the restriction concave portion 35, the four surfaces (25a to 25d) of the restriction convex portion 25 abut on the four inner wall surfaces (35a to 35d) of the restriction concave portion 35, respectively. In other words, the upper surface 25a and the lower surface 25b of the restricting convex portion abut on the inner wall upper surface 35a and the inner wall lower surface 35b of the restricting concave portion, respectively. Based on this vertical contact relationship, the vertical movement of the lid 30 relative to the base body 20 is restricted. Further, the terminal side surface 25c and the central side surface 25d of the restricting convex part come into contact with the inner wall terminal side surface 35c and the inner wall central side surface 35d of the restricting concave part, respectively. Based on the front-rear (FIG. 5) contact relationship, the front-rear movement (longitudinal movement) of the lid 30 with respect to the base body 20 is restricted. In this manner, the base 20 and the lid 30 can be firmly fixed to each other by fitting the regulation convex portion 25 of the base and the regulation concave 35 of the lid.

次に図８（Ｂ）に示すように、組立てが完了したエンドキャップ８をベルトモール本体７の端部（欠損部１６）に差し込むと共に、エンドキャップ８をベルトモール本体７に接着剤で接着して固定する。その結果、欠損部１６はエンドキャップ８で覆い隠される。この後、エンドキャップ８のクリップ片２６をドアパネル２のクリップ止め部に係合させることで、ベルトモール６をドアパネル２に取り付けることができる。 Next, as shown in FIG. 8B, the assembled end cap 8 is inserted into the end portion (defect portion 16) of the belt molding body 7, and the end cap 8 is bonded to the belt molding body 7 with an adhesive. And fix. As a result, the missing part 16 is covered with the end cap 8. Thereafter, the belt molding 6 can be attached to the door panel 2 by engaging the clip piece 26 of the end cap 8 with the clip stopper of the door panel 2.

本実施形態のベルトモール６によれば、エンドキャップ８の基体２０の被せ部２２でベルトモール本体７の欠損部１６の上方を覆うことにより、並びに、エンドキャップ８の蓋体３０の蓋体本体部３１および覆い部３２でベルトモール本体７の端面および該端面の外周縁位置を覆うことにより、ベルトモール本体７の端部領域の外観を向上させることができる。また本実施形態では、上述のように、基体２０の規制凸部２５および蓋体３０の規制凹部３５の嵌合関係、並びに、基体２０の基体係止部２４および蓋体３０の蓋体係止部（突起部３３）の係合関係に基づいて、基体２０に対する蓋体３０の上下方向移動、前後方向移動（長手方向移動）並びに内外方向移動（車内側および車外側への相対変位）を効果的に規制することができる。それ故、エンドキャップ８が基体２０および蓋体３０からなるツーピース構造を採用するにもかかわらず、基体２０と蓋体３０とが互いに位置ズレしたりガタついたりすることを防止して、基体２０と蓋体３０との相対配置関係を確定的又は固定的に保持することができる。従ってベルトモール６をドアパネル２に取り付けた場合でも、基体２０の被せ部２２と蓋体３０の覆い部３２との間に無視し得ない大きさの隙間が発生するのを防止して、ベルトモール６の端部領域の外観（見栄え）を良好に保つことができる。 According to the belt molding 6 of the present embodiment, the covering portion 22 of the base 20 of the end cap 8 covers the upper portion of the defective portion 16 of the belt molding main body 7, and the lid body of the lid 30 of the end cap 8. By covering the end surface of the belt molding body 7 and the outer peripheral edge position of the end surface with the portion 31 and the covering portion 32, the appearance of the end region of the belt molding body 7 can be improved. Further, in the present embodiment, as described above, the fitting relationship between the restriction convex portion 25 of the base body 20 and the restriction concave portion 35 of the lid body 30, and the base body locking portion 24 of the base body 20 and the lid body latching of the lid body 30. Based on the engagement relationship of the portion (projection portion 33), the vertical movement, forward / backward movement (longitudinal movement) and inward / outward movement (relative displacement to the vehicle interior and vehicle exterior) of the lid body 30 with respect to the base body 20 are effective. Can be regulated. Therefore, even though the end cap 8 employs a two-piece structure including the base body 20 and the lid body 30, the base body 20 and the lid body 30 are prevented from being displaced from each other or rattled. And the relative arrangement relationship between the lid 30 and the lid 30 can be held deterministically or fixedly. Therefore, even when the belt molding 6 is attached to the door panel 2, it is possible to prevent a gap having a size that cannot be ignored between the covered portion 22 of the base body 20 and the covering portion 32 of the lid 30 from occurring. The appearance (appearance) of the end region 6 can be kept good.

本発明に従うエンドキャップにおける基体の規制凸部および蓋体の規制凹部は、上記のような規制凸部２５（図５）および規制凹部３５（図７）に限定されるものではなく、本発明の趣旨に従う限り適宜設計変更可能である。例えば図９および図１０に示すような形状としてもよい。 [Other Embodiments]
The restriction convex part of the base body and the restriction concave part of the lid body in the end cap according to the present invention are not limited to the restriction convex part 25 (FIG. 5) and the restriction concave part 35 (FIG. 7) as described above. As long as the purpose is followed, the design can be changed as appropriate. For example, the shape shown in FIGS. 9 and 10 may be used.

図９に示す規制凸部１２５は、基体本体部２１から車外側に向けてあたかも「凸」字状に突出した多面体状のブロック体として形成されている。この規制凸部１２５は、図５の規制凸部２５と同様、上面１２５ａ、下面１２５ｂ、末端側側面１２５ｃ、中央側側面１２５ｄ、車外側端面１２５ｅ、更には、この車外側端面１２５ｅよりも低い位置で且つ車内側寄りの奥まった位置にある段差部端面１２５ｆを有している。これらの面１２５ａ〜１２５ｆの役割は、図５の規制凸部２５の対応する各面２５ａ〜２５ｆの役割と同じである。更に、規制凸部１２５には、車外側端面１２５ｅと交差する段差面１２５ｇが形成されている。 The restriction convex portion 125 shown in FIG. 9 is formed as a polyhedral block body projecting in a “convex” shape from the base body portion 21 toward the outside of the vehicle. Like the restricting convex portion 25 in FIG. 5, the restricting convex portion 125 has an upper surface 125a, a lower surface 125b, a terminal side surface 125c, a central side surface 125d, a vehicle outer end surface 125e, and a position lower than the vehicle outer end surface 125e. In addition, it has a stepped end face 125f located at the back of the vehicle interior. The roles of these surfaces 125a to 125f are the same as the roles of the corresponding surfaces 25a to 25f of the restricting convex portion 25 in FIG. Further, the regulating convex portion 125 is formed with a step surface 125g that intersects with the vehicle outer end surface 125e.

図９および図１０は、図９の規制凸部１２５に対応する規制凹部１３５を具備した蓋体１３０を示す。図９および図１０の蓋体１３０は、図５および図７の蓋体３０と基本的な構造を同じくするが、取付部１３４および規制凹部１３５の形状が前記蓋体３０とは若干異なっている。即ち図９および図１０に示すように、蓋体１３０は、図９の規制凸部１２５を嵌合可能な規制凹部１３５を区画する取付部１３４を有している。そして、その規制凹部１３５の内壁部には、規制凸部の上面１２５ａに対応する内壁上面１３５ａ、規制凸部の下面１２５ｂに対応する内壁下面１３５ｂ、規制凸部の末端側側面１２５ｃに対応する内壁末端側側面１３５ｃ、規制凸部の中央側側面１２５ｄに対応する内壁中央側側面１３５ｄが形成されている。また、規制凹部１３５の奥には段差形状の奥底面１３５ｅが形成されている。更に、規制凹部１３５の内壁部には、規制凸部１２５の段差面１２５ｇに対応する内壁段差面１３５ｇが形成されている。規制凹部１３５の上記各面１３５ａ〜１３５ｅの役割は、図７の規制凹部３５の対応する各面３５ａ〜３５ｅの役割と同じである。そして、規制凸部１２５と規制凹部１３５とを嵌合させることで、基体２０と蓋体１３０との相対配置関係を確定的又は固定的に保持できることは、図１〜８の実施形態と同じである。なお、図９および図１０の例では、規制凸部１２５の段差面１２５ｇと規制凹部１３５の内壁段差面１３５ｇとが当接することによっても、基体２０に対する蓋体１３０の上下方向の動きが規制される。 FIGS. 9 and 10 show a lid 130 having a regulation recess 135 corresponding to the regulation projection 125 of FIG. 9 and 10 has the same basic structure as the lid 30 of FIGS. 5 and 7, but the shapes of the attachment portion 134 and the regulation recess 135 are slightly different from those of the lid 30. . That is, as shown in FIG. 9 and FIG. 10, the lid body 130 has an attachment portion 134 that defines a regulation recess 135 into which the regulation projection 125 of FIG. 9 can be fitted. The inner wall portion of the restriction recess 135 includes an inner wall upper surface 135a corresponding to the upper surface 125a of the restriction protrusion, an inner wall lower surface 135b corresponding to the lower surface 125b of the restriction protrusion, and an inner wall corresponding to the terminal side surface 125c of the restriction protrusion. An inner wall central side surface 135d corresponding to the terminal side surface 135c and the central side surface 125d of the restricting convex portion is formed. A step-shaped back bottom surface 135e is formed in the back of the regulation recess 135. Furthermore, an inner wall step surface 135 g corresponding to the step surface 125 g of the restriction convex portion 125 is formed on the inner wall portion of the restriction concave portion 135. The roles of the surfaces 135a to 135e of the restricting recess 135 are the same as the roles of the corresponding surfaces 35a to 35e of the restricting recess 35 in FIG. And it is the same as that of embodiment of FIGS. 1-8 that the relative arrangement | positioning relationship of the base | substrate 20 and the cover body 130 can be hold | maintained definitely or fixedly by making the control convex part 125 and the control recessed part 135 fit. is there. 9 and 10, the vertical movement of the lid body 130 with respect to the base body 20 is also restricted by the contact between the step surface 125g of the restriction convex portion 125 and the inner wall step surface 135g of the restriction concave portion 135. The

図１〜８の実施形態および図９，１０の実施形態では、基体２０の棒状部２３の先端に位置する基体係止部２４と蓋体（３０，１３０）の突起部３３とを係合させて、蓋体が基体２０から離脱するのを防止する離脱防止構造を構築したが、この離脱防止構造は図１１及び図１２に示すような構造で代替することもできる。具体的には、蓋体に突起部３３を形成することに代えて、図１１（Ｂ１）及び（Ｂ２）に示すように、蓋体１３０の取付部１３４の上端面上に蓋体係止部１３７を突設する。他方で、基体２０の棒状部２３の先端に基体係止部２４を形成することに代えて、片持ち梁形状の棒状部２３自体を、前記蓋体係止部１３７と係合する基体係止部（２３）として利用する（図１１（Ａ１）及び（Ａ２）参照）。なお、図１１（Ａ１）及び（Ａ２）の棒状部２３の端部は、蓋体１３０を取り付けやすくするために一部がテーパー形状となっている。この離脱防止構造によれば、基体２０の規制凸部１２５を蓋体１３０の規制凹部１３５に嵌合させたとき、図１２に示すように、基体係止部としての棒状部２３と蓋体係止部１３７とが互いに係合し、この相互係合によって基体２０に対する蓋体１３０の車外側への移動（相対変位）が規制される。また、図１１及び１２の実施形態では、基体係止部としての棒状部２３を上側に変位させて棒状部２３と蓋体係止部１３７とを係合させるため、棒状部２３を上側に大きく撓ませることができる。このため、蓋体係止部１３７を所望の大きさに形成しやすく、蓋体係止部１３７と棒状部２３とを安定して係合させることができて好ましい。なお、図１２は、図２におけるＢ−Ｂ線位置での断面に相当する。 In the embodiment of FIGS. 1 to 8 and the embodiment of FIGS. 9 and 10, the base locking portion 24 located at the tip of the rod-like portion 23 of the base 20 is engaged with the protrusion 33 of the lid (30, 130). Thus, a detachment preventing structure for preventing the lid from detaching from the base body 20 is constructed, but this detachment preventing structure can be replaced with a structure as shown in FIGS. Specifically, instead of forming the projection 33 on the lid, as shown in FIGS. 11 (B1) and 11 (B2), the lid locking portion is provided on the upper end surface of the attachment portion 134 of the lid 130. 137 is projected. On the other hand, instead of forming the base locking portion 24 at the tip of the rod-shaped portion 23 of the base body 20, the cantilever-shaped rod-shaped portion 23 itself engages with the lid locking portion 137. It uses as a part (23) (refer FIG. 11 (A1) and (A2)). In addition, in order to make it easy to attach the cover body 130, the edge part of the rod-shaped part 23 of FIG. 11 (A1) and (A2) has a part taper shape. According to this structure for preventing detachment, when the restricting convex portion 125 of the base body 20 is fitted into the restricting concave portion 135 of the lid body 130, as shown in FIG. The stoppers 137 engage with each other, and the mutual engagement restricts the movement (relative displacement) of the lid body 130 relative to the base body 20 to the vehicle exterior side. Further, in the embodiment shown in FIGS. 11 and 12, the rod-like portion 23 serving as the base engaging portion is displaced upward to engage the rod-like portion 23 and the lid engaging portion 137. Can be bent. For this reason, it is preferable that the lid locking portion 137 can be easily formed in a desired size, and the lid locking portion 137 and the rod-like portion 23 can be stably engaged. 12 corresponds to a cross section taken along the line BB in FIG.
