Description

本発明は、車両用板状体である窓ガラスを車両本体の窓用開口枠部に仮止めするための仮止めクリップ及び仮止めクリップの製造方法並びに仮止めクリップ付き窓用板状体に関する。   The present invention relates to a temporary fixing clip for temporarily fixing a window glass, which is a vehicle plate-like body, to a window opening frame portion of a vehicle body, a method for manufacturing the temporary fixing clip, and a window plate-like body with a temporary fixing clip.

近年、車両の窓用開口枠部により形成される開口部に取り付けられる車両用窓ガラスは、開口枠部にウレタン系等の接着剤によって固定されている。この窓ガラスの固定方法は、接着剤が硬化して所定の接着強度を得るまでに数時間を要することから、窓ガラス側に仮止めクリップをあらかじめ固着しておき、この仮止めクリップを開口枠部に形成された嵌合用孔に嵌着することにより、接着剤が硬化するまでの間、窓ガラスを開口枠部に仮止めするようにしている。   In recent years, a vehicle window glass attached to an opening formed by an opening frame portion for a vehicle window is fixed to the opening frame portion with an adhesive such as urethane. This window glass fixing method requires several hours for the adhesive to harden and obtain a predetermined adhesive strength. Therefore, the temporary fixing clip is fixed to the window glass in advance, and the temporary fixing clip is attached to the opening frame. The window glass is temporarily fixed to the opening frame until the adhesive is cured by fitting in the fitting hole formed in the part.

特許文献1に開示された仮止めクリップのクリップ本体は、PBT又は硬質PVCで形成されており、略直方体状の基部と、基部の側面から水平に延出するアームと、基部の上面から上方に延出する爪部とによって構成されている。また、この仮止めクリップの底面は、窓ガラスに対する溶着を促進するために板状の軟質PVCシートが接着されている。この仮止めクリップを窓ガラスの所定の位置に溶着し、仮止めクリップの爪部を、車両の開口枠部に形成された嵌合用孔に嵌着することにより、窓ガラスを仮止めする。   The clip body of the temporary fixing clip disclosed in Patent Document 1 is formed of PBT or rigid PVC, and has a substantially rectangular parallelepiped base, an arm extending horizontally from the side of the base, and an upper surface of the base upward. It is comprised by the nail | claw part extended. In addition, a plate-like soft PVC sheet is bonded to the bottom surface of the temporary fixing clip in order to promote welding to the window glass. The temporary fixing clip is welded to a predetermined position of the window glass, and the window glass is temporarily fixed by fitting the claw portion of the temporary fixing clip into the fitting hole formed in the opening frame portion of the vehicle.

特許文献1の仮止めクリップのクリップ本体は、硬質樹脂で射出成形することにより製造され、このクリップ本体の底面に前記軟質PVCシートを後工程にて接着している。   The clip main body of the temporarily fixing clip of Patent Document 1 is manufactured by injection molding with a hard resin, and the soft PVC sheet is bonded to the bottom surface of the clip main body in a subsequent process.

特許第3680270号公報Japanese Patent No. 3680270

しかしながら、特許文献1の仮止めクリップは、車体に発生した振動、コーナーリング時やタイヤの突き上げ時に生じる車体の捩れ等に起因して、クリップ本体と嵌合用孔の縁部とが擦れ合い、その部分から擦過音、きしみ音、低級音等の異音が発生するという欠点があった。異音の発生原因は、硬質樹脂製のクリップ本体と自動車用鋼板製の窓用開口枠部の硬質部材同士が擦れ合うことにあると考えられる。   However, the temporary fixing clip of Patent Document 1 rubs the clip main body and the edge of the fitting hole due to vibrations generated in the vehicle body, torsion of the vehicle body that occurs when cornering or pushing up the tire, and the like. Therefore, there is a drawback that abnormal noise such as scratching sound, squeak noise, and low-order sound is generated. The cause of abnormal noise is considered to be that the hard members of the clip body made of hard resin and the window opening frame made of steel plate for automobiles rub against each other.

よって、このような異音問題は、クリップ本体の、嵌合用孔の縁部に当接する部分に不織布等の緩衝部材を貼り付け、この緩衝部材によって硬質部材同士の擦れ合いを緩衝することにより解消できる。しかし、緩衝部材付きの仮止めクリップを製造するためには、緩衝部材を貼り付ける工程が加わるため、仮止めクリップの生産性が悪くなりコストが増大するという問題があった。   Therefore, such an abnormal noise problem is solved by attaching a cushioning member such as a nonwoven fabric to the portion of the clip body that contacts the edge of the fitting hole, and cushioning the friction between the hard members by this cushioning member. it can. However, in order to manufacture the temporary fixing clip with the buffer member, a process of attaching the buffer member is added, which causes a problem that productivity of the temporary fixing clip is deteriorated and cost is increased.

本発明は、このような事情に鑑みてなされたもので、車体側との擦れ合いに起因する異音の発生を防止するとともに生産性の高い仮止めクリップ及び仮止めクリップの製造方法並びに仮止めクリップ付き窓用板状体を提供することを目的とする。   The present invention has been made in view of such circumstances, and prevents temporary noise caused by friction with the vehicle body side, and has a high productivity and a temporary fixing clip manufacturing method and a temporary fixing. It aims at providing the plate-like body for windows with a clip.

本発明の仮止めクリップは、前記目的を達成するために、基部と、前記基部の底面に略平行に形成された基台部と、前記基部の上面から該基部の底面に対して略平行に延出形成された爪部とからなる樹脂製のクリップ本体を備え、前記基台部と前記爪部との間の隙間に仮止め用の凹部が形成された仮止めクリップであって、前記仮止めクリップは、少なくとも二つ以上の異なる組成の樹脂材料を用いて一体に押し出し形成され、前記クリップ本体には、少なくとも前記凹部が仮止めされる車両本体と当接する面に緩衝層が一体形成され、前記緩衝層は、前記クリップ本体よりも軟質の樹脂材料によって形成されていることを特徴としている。 Temporary fixing clip of the present invention, substantially parallel in order to achieve the above object, a base, a base portion which is substantially parallel to the bottom surface of said base, the bottom surface of the base portion from the upper surface of the base consisting of extending the formed claw portion comprises a plastic clip body, a temporarily fixing clip recess for temporary fixing is formed in the gap between the claw portion and the base portion, the The temporary fixing clip is integrally formed by using resin materials having at least two different compositions , and at least a buffer layer is integrally formed on the clip main body on a surface that abuts the vehicle main body on which the concave portion is temporarily fixed. The buffer layer is formed of a resin material that is softer than the clip body .

発明によれば、基部、基台部、及び爪部からなる樹脂製のクリップ本体と、車両に当接される緩衝層とを一体形成して仮止めクリップを製造するので、後工程にて緩衝部材をクリップ本体に貼り付ける従来の仮止めクリップと比較して、高い生産性を得ることができる。また、一体成形された緩衝層により車体側との擦れ合いによる異音の発生を防止することができる。一体成形の手法としては、仮止めクリップの断面形状に対応した金型から樹脂材料を押し出すことにより仮止めクリップを成形する押出成形法、仮止めクリップの形状に対応した空間を有する金型に樹脂材料を射出することにより仮止めクリップを成形する射出成形法がある。 According to the present invention, since the clip main body made of resin including the base portion, the base portion, and the claw portion and the buffer layer that comes into contact with the vehicle are integrally formed, the temporary fixing clip is manufactured. High productivity can be obtained compared with the conventional temporary fix | stop clip which affixes a buffer member to a clip main body. In addition, the integrally formed buffer layer can prevent the generation of abnormal noise due to friction with the vehicle body side. As a method of integral molding, an extrusion molding method for molding a temporary fixing clip by extruding a resin material from a mold corresponding to the cross-sectional shape of the temporary fixing clip, a resin having a space corresponding to the shape of the temporary fixing clip There is an injection molding method in which a temporary fixing clip is formed by injecting a material.

発明によれば、緩衝層はクリップ本体よりも軟質の樹脂製であるので、車両との擦れ合いを緩衝することができ、異音の発生を防止することができる。一方でクリップ本体は、板状体を所定の位置に位置ずれすることなく仮止めする必要があるため、剛性のある硬質の樹脂材料で製造される。ここで硬質とはHsA85以上、好ましくはHsA85〜100、更に好ましくはHsA85〜95までの樹脂を指し、軟質樹脂とはHsA85以下、好ましくはHsA50〜70、更に好ましくはHsA55〜65までの樹脂を指す。HsA85未満であると、クリップ本体に要求される仮止め機能が低下し、HsA70を超えると、擦れ合いの緩衝機能が低下するからである。また、HsA60未満であっても緩衝機能が得られるが、あまりにも軟質であると、仮止め機能に悪影響を及ぼす。このような理由から、双方の機能を兼備するため緩衝層の硬さはHsA60以上が好ましい。クリップ本体の樹脂材料としては、硬質塩化ビニル樹脂(PVC)又はポリブチレンテレフタレート(PBT)等の熱可塑性樹脂、緩衝層の樹脂材料としては、軟質ΡVC又は塩素化エチレンコポリマー架橋体アロイによる熱可塑性ゴム(商品名:アルクリン(米国デュポン社製))を例示できる。 According to the present invention, since the buffer layer is made of a softer resin than the clip body, the friction with the vehicle can be buffered, and the generation of abnormal noise can be prevented. On the other hand, the clip main body is manufactured from a rigid hard resin material because the plate-like body needs to be temporarily fixed without being displaced in a predetermined position. Here, hard means a resin of HsA85 or more, preferably HsA85 to 100, more preferably HsA85 to 95, and soft resin means a resin of HsA85 or less, preferably HsA50 to 70, more preferably HsA55 to 65. . This is because if it is less than HsA85, the temporary fixing function required for the clip body is lowered, and if it exceeds HsA70, the frictional buffering function is lowered. Moreover, even if it is less than HsA60, a buffer function is obtained, but if it is too soft, the temporary fixing function is adversely affected. For these reasons, the hardness of the buffer layer is preferably HsA60 or higher in order to have both functions. The resin material for the clip body is a thermoplastic resin such as hard vinyl chloride resin (PVC) or polybutylene terephthalate (PBT), and the resin material for the buffer layer is a thermoplastic rubber made of soft cocoon VC or a chlorinated ethylene copolymer crosslinked alloy. (Product name: Alclin (manufactured by DuPont, USA)).

発明は、前記クリップ本体の窓用板状体と当接される面には接着層が形成され、該接着層は前記クリップ本体よりも軟質の樹脂材料によって形成されていることを特徴とする。 The present invention, before Symbol the window plate body and contact the surface to the clip body adhesive layer is formed, the adhesive layer and characterized in that it is formed of a resin material softer than the clip body To do.

発明によれば、クリップ本体の窓用板状体と当接される面に接着層を形成したので、窓用板状体に仮止めクリップを容易に取り付けることができる。この接着層は、クリップ本体の成形後にクリップ本体に接着してもよいが、生産性を高めることから緩衝層と同様にクリップ本体と一体形成することが好ましい。また、この接着層は、車体からクリップ本体を介して伝達された振動を、窓用板状体に伝達することなく緩衝するために、軟質の樹脂製であることが好ましい。 According to the present invention, since the adhesive layer is formed on the surface of the clip body that is in contact with the window plate, the temporary fixing clip can be easily attached to the window plate. The adhesive layer may be adhered to the clip body after the clip body is formed, but it is preferably formed integrally with the clip body in the same manner as the buffer layer in order to increase productivity. In addition, the adhesive layer is preferably made of a soft resin in order to buffer the vibration transmitted from the vehicle body via the clip body without transmitting it to the window plate.

発明は、前記緩衝層と前記接着層とが同一の樹脂材料によって前記クリップ本体に一体成形されていることを特徴とする。 The present invention is characterized in that the front Symbol buffer layer and the adhesive layer is integrally formed on the clip body by a same resin material.

発明によれば、緩衝層は擦れ合いによる異音を防止することを目的とし、接着層は振動を緩衝することを目的としており、目的はそれぞれ異なるが、双方の目的を達成する樹脂の特性は、クリップ本体よりも軟質であることを要する。よって、緩衝層及び接着層をわざわざ別の軟質樹脂とするのではなく、同一の樹脂とすることにより、樹脂材料の管理が容易になり、また、樹脂材料のコストを削減することができる。 According to the present invention, the buffer layer is intended to prevent abnormal noise due to rubbing, and the adhesive layer is intended to cushion vibrations. The purpose of the resin is to achieve both purposes, although the purpose is different. Needs to be softer than the clip body. Therefore, by making the buffer layer and the adhesive layer different from each other and using the same resin, management of the resin material can be facilitated, and the cost of the resin material can be reduced.

本発明の仮止めクリップの製造方法は、前記目的を達成するために、本発明の仮止めクリップは、少なくとも二つ以上の異なる組成の樹脂材料を用いて一体に成形されて製造されることを特徴とする。 Temporary fixing clip production how the present invention, in order to achieve the above object, the temporary fixing clip of the present invention, be produced with integrally formed with at least two different compositions of resinous material It is characterized by.

発明によれば、少なくとも二つ以上の異なる組成の樹脂材料を用いて一体に成形することにより、仮止めクリップを製造する。これにより、高い生産性を得ることができるとともに、前記樹脂材料のうち軟質の樹脂材料によって、車体側との擦れ合いによる異音の発生を防止することができる。 According to the present invention, the temporary fixing clip is manufactured by integrally molding at least two resin materials having different compositions. Thereby, high productivity can be obtained, and generation of abnormal noise due to friction with the vehicle body can be prevented by the soft resin material of the resin materials.

発明前記仮止めクリップは、まず、一体に押し出し成形された後に1個長分に分断され、次に、前記分断された仮止めクリップ成形体を切削加工することにより製造されることを特徴とする。 The temporary fixing clip of the present invention is manufactured by first extruding integrally and then dividing into one piece, and then cutting the divided temporary fixing clip molded body. And

発明によれば、少なくとも二つ以上の異なる組成の樹脂材料を用いて一体に押し出し成形(多層同時押し出し形成)することにより仮止めクリップを製造する。例えば、ダイと称される金型の出口から樹脂材料を押し出すことにより、仮止めクリップを押し出し形成する。このダイの出口には、クリップ本体用樹脂材料と緩衝層用樹脂材料とを隔離する隔壁が設けられ、クリップ本体用樹脂材料と緩衝層用樹脂材料とをダイの出口に設けられた別々の出口より押し出し、押し出されたクリップ本体部と緩衝層部とを融着させて仮止めクリップを成形する方法を例示できる。 According to the present invention, a temporary fixing clip is manufactured by integrally extruding (multi-layer simultaneous extrusion formation) using at least two resin materials having different compositions. For example, a temporary fixing clip is formed by extruding a resin material from an outlet of a mold called a die. The outlet of the die is provided with a partition that separates the clip body resin material and the buffer layer resin material, and the clip body resin material and the buffer layer resin material are provided separately at the exit of the die. A method of forming a temporary clip by fusing the extruded clip body portion and the buffer layer portion together can be exemplified.

このように多層同時押し出し成形により仮止めクリップを製造することにより、短時間で仮止めクリップを製品化できるので、コストダウンを図ることができる。また、押し出し成形は、ダイの金型の形状を変えるだけで、製品の断面形状を自由に変更できる特性を有しているので、仮止めクリップの形状を自由に設定することができるとともに製品設計の自由度が広がる利点がある。   As described above, by manufacturing the temporary fixing clip by multilayer simultaneous extrusion, the temporary fixing clip can be commercialized in a short time, so that the cost can be reduced. Extrusion molding has the property that the cross-sectional shape of the product can be freely changed simply by changing the shape of the die mold, so that the shape of the temporary clip can be set freely and the product design There is an advantage that the degree of freedom increases.

本発明の仮止めクリップ付き窓用板状体は、前記目的を達成するために、本発明の仮止めクリップが固着されたことを特徴とする。 Tacking clip attached window plate-like body of the present invention, in order to achieve the above object, the temporary fixing clip of the present invention is characterized in that it is fixed.

発明によれば、本発明の仮止めクリップが固着された仮止めクリップ付き窓用板状体を提供する。すなわち、車体との間で擦れ合いにより生じる異音の発生を防止した仮止めクリップ付きの窓用板状体を提供できる。板状体としては、単板ガラス、強化ガラス、合わせガラス等のガラス板の他、ポリカーボネート類やポリスチレン類等のいわゆる有機透明樹脂材等を例示できる。 According to the present invention provides a temporary fixing clip attached window plate body tacking clip is fixed in the present invention.

以下、添付図面に従って本発明に係る仮止めクリップ及び仮止めクリップの製造方法並びに仮止めクリップ付き窓用板状体の好ましい実施の形態について説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a temporary fixing clip, a method of manufacturing a temporary fixing clip, and a window plate with a temporary fixing clip according to the present invention will be described with reference to the accompanying drawings.

図1は、実施の形態の仮止めクリップ付き窓用板状体10の斜視図、図2は、その仮止めクリップ12の斜視図がそれぞれ示されている。   FIG. 1 is a perspective view of a plate 10 for a window with a temporary fixing clip according to the embodiment, and FIG. 2 is a perspective view of the temporary fixing clip 12.

図1に示す仮止めクリップ付き窓用板状体10は、車両の窓用開口枠部により形成される開口部に取り付けられる略矩形状の車両用窓ガラスであり、その周縁部にはモールド、ガーニッシュと称される樹脂製の周縁部材14が一体に固着されている。そして、この窓用板状体10のコーナー部近傍位置に実施の形態の仮止めクリップ12、12が固着されている。   1 is a substantially rectangular vehicle window glass that is attached to an opening formed by an opening frame portion for a vehicle window. A resin peripheral member 14 called garnish is integrally fixed. The temporary fixing clips 12 and 12 of the embodiment are fixed to positions near the corners of the window plate 10.

なお、実施の形態の窓用板状体10としては単板ガラスを例示するが、これに限定されるものではなく、例えば強化ガラス、合わせガラス等のガラス板の他、ポリカーボネート類やポリスチレン類等のいわゆる有機透明樹脂材製の板状体であってもよい。   In addition, although the single plate glass is illustrated as the plate 10 for windows of embodiment, it is not limited to this, For example, besides glass plates, such as tempered glass and a laminated glass, polycarbonates, polystyrenes, etc. A plate-like body made of a so-called organic transparent resin material may be used.

また、実施の形態では、2個の仮止めクリップ12、12をコーナー部近傍位置に固着した窓用板状体10を例示しているが、1枚の窓用板状体10に対する仮止めクリップ12の個数及び固着位置はこれに限定されるものではなく、車両の窓用開口枠部に形成される嵌合用孔の個数及び位置に依存する。   Further, in the embodiment, the window plate 10 having the two temporary fixing clips 12 and 12 fixed in the vicinity of the corner portion is illustrated. However, the temporary clip for the single window plate 10 is illustrated. The number of 12 and the fixing position are not limited to this, and depend on the number and position of the fitting holes formed in the window opening frame of the vehicle.

更に、窓用板状体10に対する仮止めクリップ12の固着方法としては、図3の如く窓用板状体10の表面にプライマー16を塗布し、このプライマー16の塗布部に仮止めクリップ12の基台部18を載置し、仮止めクリップ12を加圧しつつ振動させて、窓用板状体10に仮止めクリップ12を超音波溶着する方法が知られている。   Further, as a method of fixing the temporary clip 12 to the window plate 10, a primer 16 is applied to the surface of the window plate 10 as shown in FIG. 3, and the temporary clip 12 is applied to the primer 16 application portion. A method is known in which the base portion 18 is placed, the temporary fixing clip 12 is pressurized and vibrated, and the temporary fixing clip 12 is ultrasonically welded to the window plate 10.

一方、仮止めクリップ12の基台部18の下面全域には、溶着促進層(接着層)20が一体形成され、この溶着促進層20の溶着促進作用により窓用板状体10に対する仮止めクリップ12の溶着時間が短縮されている。溶着促進層20は、樹脂製品である仮止めクリップ12との相溶性がよく、且つ仮止めクリップ12より短時間で溶融する軟質の材料、例えば、軟質ΡVC等で形成されることが好ましい。この軟質PVCは溶着を促進する他、軟質であるが故に衝撃吸収機能も有している。   On the other hand, a welding promotion layer (adhesive layer) 20 is integrally formed on the entire lower surface of the base portion 18 of the temporary fastening clip 12, and the temporary fastening clip for the window plate 10 by the welding promotion action of the welding promotion layer 20. 12 welding time is shortened. The welding promotion layer 20 is preferably formed of a soft material that has good compatibility with the temporary fixing clip 12 that is a resin product and melts in a shorter time than the temporary fixing clip 12, for example, a soft bag VC. This soft PVC not only promotes welding but also has an impact absorbing function because it is soft.

ところで、実施の形態の仮止めクリップ12は図2の如く、断面が台形の角柱状の基部22と、基部22の底面に略平行に一体形成された板状の基台部18と、基部22の上面から基部22の底面に対して略平行に延出形成された爪部24とからなる樹脂製のクリップ本体26を備えている。また、基台部18と爪部24との間の隙間には、仮止め用の凹部28が形成され、更にクリップ本体26には、少なくとも凹部28が仮止めされる車両本体と当接する面に緩衝層30が一体形成されている。   By the way, as shown in FIG. 2, the temporary fixing clip 12 of the embodiment has a trapezoidal prism-shaped base portion 22, a plate-like base portion 18 integrally formed substantially parallel to the bottom surface of the base portion 22, and a base portion 22. A clip main body 26 made of a resin is provided that includes a claw portion 24 that extends substantially parallel to the bottom surface of the base portion 22. Further, a recess 28 for temporary fixing is formed in the gap between the base portion 18 and the claw portion 24, and the clip main body 26 has at least a surface in contact with the vehicle main body to be temporarily fixed. The buffer layer 30 is integrally formed.

この仮止めクリップ12は、図4に示すように、車両の鋼板製窓用開口枠部32に形成される嵌合用孔34に爪部24の凹部28が挿入されるととともに、凹部28と基部22との境界コーナー部29が、嵌合用孔34の近傍のL字状フック部35に係合されることにより嵌合用孔34に取り付けられる。この状態において、クリップ本体26は緩衝層30を介して窓用開口枠部32に当接されるため、接着剤36が硬化するまでの間、窓用板状体10が窓用開口枠部32に仮止めされる。なお、この接着剤36は、窓用板状体10の周縁部に予め塗布されたウレタン系等の接着剤である。   As shown in FIG. 4, the temporary fastening clip 12 includes a recess 28 of a claw 24 inserted into a fitting hole 34 formed in an opening frame 32 for a steel plate window of a vehicle, and a recess 28 and a base. 22 is attached to the fitting hole 34 by engaging the L-shaped hook part 35 in the vicinity of the fitting hole 34. In this state, the clip main body 26 is brought into contact with the window opening frame portion 32 via the buffer layer 30, so that the window plate 10 is held until the adhesive 36 is cured. Temporarily fixed. The adhesive 36 is a urethane-based adhesive or the like previously applied to the peripheral edge of the window plate 10.

このように構成されて使用される仮止めクリップ12によれば、基部22、基台部18、及び爪部24からなる樹脂製のクリップ本体26と、車両側の窓用開口枠部32に当接される緩衝層30とが一体形成されることにより製造されるので、後工程にて緩衝部材をクリップ本体に貼り付ける従来の仮止めクリップと比較して、高い生産性を得ることができる。また、一体成形された緩衝層30により、窓用開口枠部32との擦れ合いによる異音の発生を防止することができる。一体成形の手法としては、仮止めクリップ12の断面形状に対応した金型の出口から樹脂材料を押し出すことにより仮止めクリップを成形する押出成形法、仮止めクリップ12の形状に対応した空間を有する金型に樹脂材料を射出することにより仮止めクリップを成形する射出成形法を例示できる。   According to the temporary fixing clip 12 configured and used in this manner, the resin clip main body 26 including the base portion 22, the base portion 18, and the claw portion 24 and the window opening frame portion 32 on the vehicle side are contacted. Since it is manufactured by integrally forming the buffer layer 30 that is in contact with the buffer layer 30, higher productivity can be obtained as compared with a conventional temporary fixing clip in which the buffer member is attached to the clip body in a later step. Further, the integrally formed buffer layer 30 can prevent the generation of abnormal noise due to friction with the window opening frame portion 32. As an integral molding method, there is an extrusion molding method in which a temporary fixing clip is formed by extruding a resin material from an outlet of a mold corresponding to the cross-sectional shape of the temporary fixing clip 12, and a space corresponding to the shape of the temporary fixing clip 12 is provided. An injection molding method in which a temporary fixing clip is molded by injecting a resin material into a mold can be exemplified.

また、この緩衝層30は、クリップ本体26よりも軟質の樹脂によって形成されている。このように緩衝層30が、クリップ本体26よりも軟質であると、硬質のクリップ本体26と車両用鋼板製の窓用開口枠部32との硬質部材同士の擦れ合いを緩衝することができ、異音の発生を防止することができる。   The buffer layer 30 is formed of a softer resin than the clip body 26. Thus, if the buffer layer 30 is softer than the clip body 26, the friction between the hard members of the hard clip body 26 and the window opening frame portion 32 made of a steel plate for vehicles can be buffered. Generation of abnormal noise can be prevented.

一方でクリップ本体26は、窓用板状体10を所定の位置に位置ずれすることなく仮止めする必要があるため、前述の如く剛性のある硬質の樹脂材料によって製造される。ここで硬質とはHsA85以上、好ましくはHsA85〜100、更に好ましくはHsA85〜95までの樹脂を指し、軟質樹脂とはHsA85以下、好ましくはHsA50〜70、更に好ましくはHsA55〜65までの樹脂を指す。HsA85未満であると、クリップ本体26に要求される仮止め機能が低下し、HsA70を超えると、擦れ合いの緩衝機能が低下するからである。また、HsA60未満であっても緩衝機能が得られるが、あまりにも軟質であると、仮止め機能に悪影響を及ぼす。このような理由から、双方の機能を兼備するため緩衝層30の硬さはHsA60以上が好ましい。クリップ本体26の樹脂材料としては、硬質塩化ビニル樹脂(PVC)又はポリブチレンテレフタレート(PBT等の熱可塑性樹脂、緩衝層30の樹脂材料としては、軟質ΡVC又は塩素化エチレンコポリマー架橋体アロイによる熱可塑性ゴム(商品名:アルクリン(米国デュポン社製)))、ウレタン系熱可塑性エラストマー(TPU)、アクリロニトリル・ブタジエン・スチレン樹脂(ABS)、アクリレート・スチレン・アリロニトリル(ASA)、接着促進層20の樹脂材料としては、軟質PVCを例示できる。クリップ12は、上記の材料から二つ又は三つ以上の材料を適宜組み合わせて製造される。   On the other hand, the clip body 26 is manufactured by a rigid hard resin material as described above because the window plate 10 needs to be temporarily fixed without being displaced in a predetermined position. Here, hard means a resin of HsA85 or more, preferably HsA85 to 100, more preferably HsA85 to 95, and soft resin means a resin of HsA85 or less, preferably HsA50 to 70, more preferably HsA55 to 65. . This is because if it is less than HsA85, the temporary fixing function required for the clip body 26 is lowered, and if it exceeds HsA70, the frictional buffering function is lowered. Moreover, even if it is less than HsA60, a buffer function is obtained, but if it is too soft, the temporary fixing function is adversely affected. For this reason, the hardness of the buffer layer 30 is preferably HsA60 or more in order to have both functions. The resin material of the clip body 26 is a hard vinyl chloride resin (PVC) or a polybutylene terephthalate (a thermoplastic resin such as PBT), and the resin material of the buffer layer 30 is a thermoplastic resin made of soft straw VC or a chlorinated ethylene copolymer cross-linked alloy Rubber (trade name: Alclin (manufactured by DuPont USA))), urethane-based thermoplastic elastomer (TPU), acrylonitrile / butadiene / styrene resin (ABS), acrylate / styrene / allylonitrile (ASA), resin material for adhesion promoting layer 20 As an example, soft PVC can be exemplified. The clip 12 is manufactured by appropriately combining two or more materials from the above materials.

更に、仮止めクリップ12は前述の如く、クリップ本体26の窓用板状体10と当接される面には接着促進層20が形成され、この接着層20はクリップ本体26よりも軟質の樹脂材料によって形成されている。このように、クリップ本体26の窓用板状体10と当接される面に接着促進層20を形成することにより、窓用板状体10に仮止めクリップ12を短時間で容易に固着することができる。この接着促進層20は、クリップ本体26の成形後にクリップ本体26に接着してもよいが、生産性を高めることから緩衝層30と同様にクリップ本体26と一体形成することが好ましい。また、この接着促進層20は、車両からクリップ本体26を介して伝達された振動を、窓用板状体10に伝達することなく緩衝するために、上述の如く軟質の樹脂(軟質PVC)であることが好ましい。   Further, as described above, the temporary fastening clip 12 is provided with the adhesion promoting layer 20 on the surface of the clip body 26 that is in contact with the window plate 10, and the adhesion layer 20 is a resin that is softer than the clip body 26. It is made of material. In this way, by forming the adhesion promoting layer 20 on the surface of the clip body 26 that comes into contact with the window plate 10, the temporary fixing clip 12 is easily fixed to the window plate 10 in a short time. be able to. The adhesion promoting layer 20 may be adhered to the clip body 26 after the clip body 26 is formed, but it is preferably formed integrally with the clip body 26 in the same manner as the buffer layer 30 in order to increase productivity. Further, the adhesion promoting layer 20 is made of a soft resin (soft PVC) as described above in order to buffer the vibration transmitted from the vehicle through the clip body 26 without transmitting it to the window plate 10. Preferably there is.

実施の形態の仮止めクリップ12では、緩衝層30は擦れ合いによる異音を防止することを目的とし、接着促進層20は振動を緩衝することを目的としており、目的はそれぞれ異なるが、双方の目的を達成する樹脂の特性は、クリップ本体26よりも軟質であることを要する。よって、緩衝層30及び接着促進層20をわざわざ別の軟質樹脂とするのではなく、同一の樹脂(例えば軟質PVC)とすることにより、多数の樹脂材料を管理するよりもその管理が容易になる。また、樹脂材料のコストも削減することができる。すなわち、仮止めクリップ12は、少なくとも二つ以上の異なる組成の樹脂材料を用いて一体に成
形されて製造される。これにより、高い生産性を得ることができる。
In the temporary fixing clip 12 according to the embodiment, the buffer layer 30 is intended to prevent abnormal noise due to rubbing, and the adhesion promoting layer 20 is intended to cushion vibrations. The characteristic of the resin that achieves the purpose needs to be softer than the clip body 26. Therefore, by using the same resin (for example, soft PVC) instead of making the buffer layer 30 and the adhesion promoting layer 20 different soft resins, the management becomes easier than managing a large number of resin materials. . In addition, the cost of the resin material can be reduced. That is, the temporary fixing clip 12 is manufactured by being integrally molded using at least two resin materials having different compositions. Thereby, high productivity can be obtained.

次に、図を参照して仮止めクリップ12の製造方法の一例を説明する。   Next, an example of a method for manufacturing the temporary fixing clip 12 will be described with reference to the drawings.

図5は、仮止めクリップ12の押出成形装置50の要部を示す斜視図であり、この押出成形装置50は、少なくとも二つ以上の異なる組成の樹脂材料を用いて一体に押し出すことにより仮止めクリップ12を製造する。   FIG. 5 is a perspective view showing a main part of the extrusion molding device 50 of the temporary fixing clip 12, and this extrusion molding device 50 is temporarily fixed by extruding it integrally using resin materials having at least two different compositions. The clip 12 is manufactured.

ダイ52と称される成形金型の出口は、その断面形状が仮止めクリップの断面形状に合わせて形成されており、この出口には図6に示すように、クリップ本体用樹脂材料と緩衝層用樹脂材料とを隔離する略杓子状の隔壁54が設けられるとともに、クリップ本体用樹脂材料と接着促進層用樹脂材料とを隔離する略L字状の一対の隔壁56、56が設けられている。   The outlet of the molding die called die 52 is formed so that the cross-sectional shape thereof matches the cross-sectional shape of the temporary clip, and at this outlet, as shown in FIG. A substantially insulator-shaped partition wall 54 that separates the resin material from the resin is provided, and a pair of substantially L-shaped partition walls 56 and 56 that separate the resin material for the clip body and the resin material for the adhesion promoting layer are provided. .

そして、クリップ本体用樹脂材料を不図示のクリップ本体用押出機からダイ52に供給し、ダイ52の前記出口を形成するクリップ本体用出口58より押し出し、緩衝層用樹脂材料を不図示の緩衝層用押出機からダイ52に供給し、ダイ52の前記出口を形成する緩衝層用出口60より押し出し、そして、接着促進層用樹脂材料を接着促進用押出機からダイ52に供給し、ダイ52の前記出口に設けられた接着促進層出口62より押し出す。これらの出口58、60、62から押出されたそれぞれの樹脂材料は、不図示の押付部材により互いに押し付けられて融着される。これにより、図7に示す長尺状の仮止めクリップ成形体13が連続成形される。この後、所定長さに成形された仮止めクリップ成形体13をダイ52から切断し、次に、これを1個長分に分断する。次いで、この分断した仮止めクリップ成形体13を切削加工して図2に示した仮止めクリップ12を製造する。   Then, the clip body resin material is supplied from a clip body extruder (not shown) to the die 52 and extruded from the clip body outlet 58 that forms the outlet of the die 52, and the buffer layer resin material is supplied to the buffer layer (not shown). Is supplied from the extruder for extrusion to the die 52, extruded from the buffer layer outlet 60 forming the outlet of the die 52, and the adhesion promoting layer resin material is supplied from the adhesion promotion extruder to the die 52. It extrudes from the adhesion promoting layer outlet 62 provided at the outlet. The resin materials extruded from the outlets 58, 60, 62 are pressed against each other by a pressing member (not shown) and fused. Thereby, the elongate temporary fix | stop clip molded object 13 shown in FIG. 7 is continuously shape | molded. Thereafter, the temporary fixing clip molded body 13 formed into a predetermined length is cut from the die 52, and then divided into one piece. Next, the divided temporary fixing clip molded body 13 is cut to produce the temporary fixing clip 12 shown in FIG.

このように多層同時押し出し成形により仮止めクリップ12を製造することにより、短時間で仮止めクリップ12を製品化できるので、コストダウンを図ることができる。また、押し出し成形は、ダイ52の出口の形状を変更するだけで、製品の断面形状を自由に変更できる特性を有しているので、仮止めクリップ12の形状を自由に設定することができるとともに製品設計の自由度が広がるという利点がある。   Thus, by manufacturing the temporary fixing clip 12 by multilayer simultaneous extrusion molding, the temporary fixing clip 12 can be commercialized in a short time, and thus the cost can be reduced. In addition, the extrusion molding has a characteristic that the sectional shape of the product can be freely changed only by changing the shape of the outlet of the die 52, so that the shape of the temporary fixing clip 12 can be freely set. There is an advantage that the degree of freedom in product design is expanded.

また、このような仮止めクリップ12が固着された窓用板状体10は、車体との間で擦れ合いにより生じる異音の発生を防止した仮止めクリップ付きの窓用板状体10として提供できる。   Further, the window plate 10 to which such a temporary fixing clip 12 is fixed is provided as a window plate 10 with a temporary fixing clip that prevents generation of abnormal noise caused by friction with the vehicle body. it can.

なお、図5の押出成形装置50において、符号64は金型を成形する入子であり、符号66は、入子64を鉛直方向に押下するアクチュエータであり、符号68は、ブロック70を介して入子64を水平方向に押圧するアクチュエータである。   In the extrusion molding apparatus 50 shown in FIG. 5, reference numeral 64 is an insert for forming a mold, reference numeral 66 is an actuator for pressing the insert 64 in the vertical direction, and reference numeral 68 is connected via a block 70. It is an actuator that presses the insert 64 in the horizontal direction.

更にまた、図8に示すように接着促進層20、20は、基台部18の長手方向(押出し形成方向)に複数(図2では2列)の帯状に分割して形成してもよく、一方で、図9に示すように緩衝層30を基部22の全面に形成してもよい。   Furthermore, as shown in FIG. 8, the adhesion promoting layers 20 and 20 may be formed by being divided into a plurality of strips (two rows in FIG. 2) in the longitudinal direction (extrusion forming direction) of the base portion 18, On the other hand, the buffer layer 30 may be formed on the entire surface of the base 22 as shown in FIG.

図10は、仮止めクリップ12Aの第1の変形例を示した断面図である。   FIG. 10 is a cross-sectional view showing a first modification of the temporary fixing clip 12A.

同図に示す仮止めクリップ12Aと図3に示した仮止めクリップ12との構成の相違点は、図3に示した仮止めクリップ12の凹部28に対して、図10の仮止めクリップ12Aの凹部28Aを大きめに形成し、この凹部28Aのみに緩衝層30Aを一体形成した点、及び仮止めクリップ12Aの基台部18Aの底面に接着剤80を塞き止めるための一対の凸部82、82を図11の如く一体形成した点にある。   The difference between the configuration of the temporary fixing clip 12A shown in FIG. 3 and the temporary fixing clip 12 shown in FIG. 3 is that the temporary fixing clip 12A shown in FIG. The recess 28A is formed in a large size, and the buffer layer 30A is integrally formed only in the recess 28A, and a pair of protrusions 82 for blocking the adhesive 80 on the bottom surface of the base portion 18A of the temporary fixing clip 12A. 82 is integrally formed as shown in FIG.

このように構成された仮止めクリップ12Aによれば、図12の如く、凸部82と凸部82との間のポケット84に塗布された接着剤84によって仮止めクリップ12Aが窓用板状体10に固定される。また、接着剤80は凸部82、82がスペーサーの役目を果たすことにより、接着剤80の厚さが一定になり、安定した接着力が得られる。また、仮止めクリップ12Aと窓用板状体10とによって接着剤80が塞き止められるためポケット84から流出せず、ポケット84内で固化される。このため、接着剤80の凸部82の外へのはみ出しが抑制でき、接着作業の効率が向上する。また、この仮止めクリップ12Aは、端部がストレートに形成された窓用開口枠部32の嵌合用孔34に、クリップ本体26Aの爪部24Aが嵌合される。   According to the temporary fixing clip 12A configured as described above, the temporary fixing clip 12A is formed into the window plate by the adhesive 84 applied to the pocket 84 between the convex portions 82 as shown in FIG. 10 is fixed. Further, since the convex portions 82 and 82 serve as spacers in the adhesive 80, the thickness of the adhesive 80 becomes constant, and a stable adhesive force can be obtained. Further, since the adhesive 80 is blocked by the temporary fixing clip 12 </ b> A and the window plate 10, the adhesive 80 does not flow out of the pocket 84 and is solidified in the pocket 84. For this reason, the protrusion of the adhesive 80 to the outside of the convex portion 82 can be suppressed, and the efficiency of the bonding work is improved. Further, in the temporary fixing clip 12A, the claw portion 24A of the clip body 26A is fitted into the fitting hole 34 of the window opening frame portion 32 whose end is formed straight.

図13は、第2の変形例の仮止めクリップ12Bを利用して仮止めクリップ付き窓用板状体10が車体に取り付けられた状態を示す要部拡大断面図である。   FIG. 13 is an enlarged cross-sectional view of a main part showing a state where the window plate 10 with a temporary fixing clip is attached to the vehicle body using the temporary fixing clip 12B of the second modified example.

同図によれば、仮止めクリップ12Bの基台部18Bが両面テープ86によって窓用板状体10に固着されている。なお、両面テープ86に代えてプライマーと接着剤とによって仮止めクリップ12Bを窓用板状体10に固着してもよい。   According to the figure, the base portion 18B of the temporary fixing clip 12B is fixed to the window plate 10 by the double-sided tape 86. The temporary fixing clip 12B may be fixed to the window plate 10 with a primer and an adhesive instead of the double-sided tape 86.

また、仮止めクリップ12Bの爪部24Bが、端部がストレートに形成された窓用開口枠部32の嵌合用孔34に嵌合される。   Further, the claw portion 24B of the temporary fixing clip 12B is fitted into the fitting hole 34 of the window opening frame portion 32 whose end portion is formed straight.

ところで、同図に示す仮止めクリップ12Bは、窓用板状体10を鉛直方向に仮止めするクリップである。窓用板状体10の仮止め中において、仮止めクリップ12Bには、窓用板状体10の質量により、すなわち、図中矢印A方向で示す窓用板状体10の重力により、図中B方向で示す力(窓用板状体10から仮止めクリップ12Bを剥離させようとする力)が加えられることになる。ここで仮止めクリップ12Bには、基台部18Bから窓用開口枠部32に当接するストッパ片88が一体形成されている。ストッパ片88が窓用開口枠部32に当接することにより、B方向で示す力を窓用開口枠部32に負荷させることができ、それにより仮止めクリップ12Bの窓用板状体10からの剥離を防止できる。また、ストッパ片88の窓用開口枠部32に当接する端面には、ゴム等の緩衝部材90が貼り付けられ、又はストッパ片90に一体形成されている。なお、同図において、符号22Bは仮止めクリップ12Bの基部、符号30Bは緩衝層である。   Incidentally, the temporary fixing clip 12B shown in the figure is a clip for temporarily fixing the window plate 10 in the vertical direction. During temporary fixing of the window plate 10, the temporary fixing clip 12 </ b> B is caused by the mass of the window plate 10, that is, due to the gravity of the window plate 10 indicated by the arrow A in FIG. The force shown in the B direction (the force for peeling the temporary fixing clip 12B from the window plate 10) is applied. Here, the temporary fastening clip 12B is integrally formed with a stopper piece 88 that comes into contact with the window opening frame portion 32 from the base portion 18B. When the stopper piece 88 abuts on the window opening frame portion 32, the force indicated in the B direction can be applied to the window opening frame portion 32, whereby the temporary clip 12B from the window plate 10 is removed. Separation can be prevented. Further, a buffer member 90 such as rubber is affixed to the end surface of the stopper piece 88 that contacts the window opening frame portion 32 or is integrally formed with the stopper piece 90. In the figure, reference numeral 22B denotes a base portion of the temporary fixing clip 12B, and reference numeral 30B denotes a buffer layer.

図14には、仮止めクリップ12Cの第3の変形例を示した断面図が示されている。   FIG. 14 is a sectional view showing a third modification of the temporary fixing clip 12C.

同図に示す仮止めクリップ12Cは、基台部18Cの底部の略中央部に凸部92を形成し、超音波溶着時において、凸部92により仮止めクリップ12Cと窓用板状体10とが確実に接触し、これを起点として仮止めクリップ12Cを窓用板状体10にプライマー16を介して確実に溶着するように構成したものである。なお、同図において、符号22Cは仮止めクリップ12Cの基部、24Cは仮止めクリップ12Cの爪部、符号30Cは緩衝層である。   The temporary fixing clip 12C shown in the figure forms a convex portion 92 at the substantially central portion of the bottom of the base portion 18C, and the temporary fixing clip 12C and the window plate 10 are formed by the convex portion 92 during ultrasonic welding. Are securely contacted, and the temporary fixing clip 12C is reliably welded to the window plate 10 via the primer 16 from the starting point. In the figure, reference numeral 22C denotes a base part of the temporary fixing clip 12C, 24C denotes a claw part of the temporary fixing clip 12C, and reference numeral 30C denotes a buffer layer.
