Abstract

<P>PROBLEM TO BE SOLVED: To provide a clip capable of firmly mounting a component to be mounted onto a mounting surface while reducing an assembly load without producing an unfitted state. <P>SOLUTION: This clip 1 comprises a fitting part 2 fitted to a thread part 8 of a stud bolt 6, a pressing part 3 extending from the lower end of a side plate 2a of the fitting part 2 and elastically pressing the component 7, and a locking part 4 extending from a side plate 2b of the fitting part 2 and locking the pressing part 3 in a retracted state. When the fitting part 2 is fitted to the thread part 8 and the locking part 4 is pressed against the component 7 together with the pressing part 3, the locking of the locking part 4 to the pressing part 3 is released. Accordingly, the assembly load in assembling can be minimized, and the unfitted state can be avoided by confirming click sound emitted instantaneously when the pressing part 3 is released from the locking part 4. Furthermore, the component 7 can be firmly mounted on the mounting surface 5 by both the elastic forces of locking claw parts 9 and 9 and the pressing force of the pressing part 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、取付面から延設されるスタッドボルトに嵌合して、被取付部品を取付面に取り付けるクリップに関するものである。 The present invention relates to a clip that fits a stud bolt extending from an attachment surface and attaches a part to be attached to the attachment surface.

従来、例えば、特許文献１には、車両の下面側において、マフラーからの放熱を遮断する遮熱板（被取付部品）を、マフラーの周面を囲うアンダパネル（取付面）に取り付ける際、アンダパネルから突設されたスタッドボルトを遮熱板内に挿通させ、遮熱板から突設したスタッドボルトにクリップを係合させて押し込み、遮熱板をアンダパネルに取り付ける形態が開示されている。また、この特許文献１で開示されたクリップは、円筒状で、内周面の周方向には、中心に向って突設される複数の係止爪部が形成され、さらに、遮熱板に当接するフランジ面から前記係止爪部が突設される部位までの距離を大きく設定した板バネ部が形成されており、係止爪部及び板バネ部の両者の弾性反発力により遮熱板の保持力を高めようとしている。 Conventionally, for example, Patent Document 1 discloses that, on the lower surface side of a vehicle, when a heat shield plate (attached part) that blocks heat radiation from the muffler is attached to an under panel (attachment surface) that surrounds the muffler peripheral surface, A configuration is disclosed in which a stud bolt projecting from a panel is inserted into a heat shield plate, a clip is engaged with a stud bolt projecting from the heat shield plate and pushed into the under panel, and the heat shield plate is attached to the under panel. Further, the clip disclosed in Patent Document 1 is cylindrical, and in the circumferential direction of the inner peripheral surface, a plurality of locking claws protruding toward the center are formed, and further, the heat shield plate A leaf spring portion is formed with a large distance from the abutting flange surface to the portion where the locking claw portion protrudes, and a heat shield plate is formed by the elastic repulsive force of both the locking claw portion and the leaf spring portion. I am trying to increase the holding power.

しかしながら、特許文献１で開示されたクリップでは、クリップに設けた係止爪部及び板バネ部の両方の弾性反発力を利用して遮熱板の保持力を高めようとしているので、組み付けの際、クリップを、係止爪部の弾性力に抗しながらスライドさせる荷重に加え、板バネ部を押し潰す荷重が必要で、しかも、このクリップが装着される部位は視認性が悪く、良好な作業性を確保することができない部位であるため、作業者はクリップが所定位置まで押し込まれたか否かが確認できず、クリップの挿入作業を途中で止め、未嵌合状態が発生する虞がある。さらに、この形態では、組み付けの際の組付荷重が相当高くなるため、組み付けのための工具が必要になる虞があり、ワンタッチでの組み付けが困難で組付作業が煩雑になる虞がある。 However, in the clip disclosed in Patent Document 1, the holding force of the heat shield plate is increased by using the elastic repulsive force of both the locking claw portion and the leaf spring portion provided in the clip. In addition to the load that slides the clip against the elastic force of the latching claw, a load that crushes the leaf spring part is required, and the part where this clip is attached has poor visibility and is a good work Therefore, the operator cannot confirm whether or not the clip has been pushed to a predetermined position, so that the clip insertion operation may be stopped halfway and an unfitted state may occur. Further, in this embodiment, since the assembly load during assembly becomes considerably high, a tool for assembly may be necessary, and assembly with one touch may be difficult and the assembly work may be complicated.

そこで、こうした問題点を解決するための従来技術として、例えば、特許文献２には、クリップの嵌合部の押圧される側の上端面に、軸方向に揺動自在となるヒンジにより嵌合部と連結された蓋部が形成され、また、嵌合部外周の押圧される側には、第１ノッチ及び第２ノッチが軸方向に並んで形成され、これら第１ノッチ及び第２ノッチとの間には、これらを分離するための当接部が形成されており、嵌合部をスタッドボルトの所定位置まで挿入させるのに十分な力で蓋部の爪を第１ノッチから第２ノッチまで移動させて、爪が第２ノッチに係合する際のクリック感及びクリック音で、嵌合部をスタッドボルトの所定位置まで挿入されたか否かを明瞭にしたクリップが開示されている。 Therefore, as a conventional technique for solving such a problem, for example, in Patent Document 2, a fitting portion is provided on an upper end surface on a pressed side of a fitting portion of a clip by a hinge that can swing in an axial direction. And a first notch and a second notch are formed side by side in the axial direction on the pressed side of the outer periphery of the fitting portion, and the first notch and the second notch A contact portion for separating them is formed between the first notch and the second notch of the lid portion with sufficient force to insert the fitting portion to a predetermined position of the stud bolt. There is disclosed a clip that is moved to clarify whether or not the fitting portion has been inserted to a predetermined position of the stud bolt by a click feeling and a clicking sound when the claw is engaged with the second notch.

しかしながら、特許文献２の発明では、クリップとスタッドボルトとの未嵌合状態に係る問題については解決されているものの、クリップをスタッドボルトの所定位置まで挿入させるためには、蓋部に相当大きい力を付与しなければならず、組み付けのための工具が必要となり、組付作業性の効率化に係る問題については、解決されていない。また、この特許文献２の発明では、嵌合部に設けた係止爪がスタッドボルトの先端ねじ軸部の周面に弾力的に当接して係合するだけの作用で、被固定物を固定面に固定しているため、被固定物を保持する保持力が不足する虞があり、まだ多くの課題を残している。 However, in the invention of Patent Document 2, although the problem relating to the unfitted state of the clip and the stud bolt is solved, in order to insert the clip to the predetermined position of the stud bolt, a considerably large force is applied to the lid portion. Therefore, a tool for assembling is required, and the problem concerning the efficiency of assembling work has not been solved. Further, in the invention of Patent Document 2, the object to be fixed is fixed by an action in which the locking claw provided in the fitting portion is elastically contacted and engaged with the peripheral surface of the tip screw shaft portion of the stud bolt. Since it is fixed to the surface, there is a risk that the holding force for holding the object to be fixed may be insufficient, and many problems still remain.

本発明は、かかる点に鑑みてなされたものであり、組み付けの際の組付荷重を低減しつつ、未嵌合状態を発生させることなく、強固に被取付部品を取付面に取り付けるクリップを提供することを目的とする。 The present invention has been made in view of the above points, and provides a clip that securely attaches a part to be attached to an attachment surface without causing an unfitted state while reducing an assembly load during assembly. The purpose is to do.

本発明は、上記課題を解決するための手段として、請求項１に記載したクリップの発明は、取付面から延び被取付部品に挿通されるスタッドの外周面に設けられた突条部に嵌合して、前記被取付部品を前記取付面に取り付けるクリップであって、前記突条部に嵌合される嵌合部と、該嵌合部の一端から延び前記被取付部品を前記取付面に弾性的に押圧する押圧手段と、前記嵌合部の他端から延び前記押圧手段を押し縮めた状態で係止する係止手段とから構成され、前記嵌合部を前記突条部に嵌合して、前記係止手段を、前記押圧手段と共に前記被取付部品に押し付けると、前記係止手段と前記押圧手段との係止が解除されることを特徴とするものである。
請求項２に記載したクリップの発明は、請求項１に記載した発明において、前記押圧手段は、前記嵌合部に連設された湾曲部と、前記スタッドが挿通される挿通孔を有する押圧アーム部とから構成され、また、前記係止手段は、前記嵌合部との境界部を中心に揺動可能な係止アーム部と、該係止アーム部の下部に設けられ、前記押圧アーム部の先端が挿脱される係止孔とから構成されており、前記押圧アーム部及び前記係止アーム部の下端が前記被取付部品に押し付けられると、前記係止アーム部が前記境界部を中心に外方に開き、前記押圧アーム部の先端が前記係止孔から離脱することを特徴とするものである。
請求項３に記載したクリップの発明は、請求項１または２に記載した発明において、前記嵌合部、前記押圧手段及び前記係止手段は、一枚のバネ鋼板を折り曲げて構成されていることを特徴とするものである。 According to the present invention, as a means for solving the above-described problems, the clip invention described in claim 1 is fitted to a protruding portion provided on an outer peripheral surface of a stud extending from a mounting surface and inserted into a mounted component. A clip for attaching the attached component to the attachment surface, the fitting portion being fitted to the protruding portion, and extending from one end of the fitting portion, the attached component being elastic to the attachment surface And pressing means that presses and contracts in a state where the pressing means is pressed and contracted, and the fitting part is fitted to the protruding part. When the locking means is pressed against the attached component together with the pressing means, the locking between the locking means and the pressing means is released.
The invention of the clip according to claim 2 is the invention according to claim 1, wherein the pressing means includes a bending portion provided continuously with the fitting portion and a pressing arm through which the stud is inserted. And the locking means is provided at a lower part of the locking arm portion, the locking arm portion being swingable about a boundary portion with the fitting portion, and the pressing arm portion. A locking hole into which the distal end of the locking arm is inserted and removed, and when the lower end of the pressing arm portion and the locking arm portion is pressed against the attached part, the locking arm portion is centered on the boundary portion. And the distal end of the pressing arm part is detached from the locking hole.
The invention of the clip described in claim 3 is the invention described in claim 1 or 2, wherein the fitting portion, the pressing means, and the locking means are configured by bending a single spring steel plate. It is characterized by.

従って、請求項１に記載したクリップの発明では、押圧手段を押し縮め係止手段に係止された状態で、嵌合部をスタッドの突条部に係合させて押し込み、押圧手段及び係止手段を被取付部品に押し付けると、押圧手段が係止手段から開放され、押圧手段の弾性力により被取付部品が取付面に押圧されると同時に、嵌合部が突条部に嵌合し、被取付部品が取付面に取り付けられる。つまり、組み付けの際の組付荷重は、押圧手段が係止手段に係止された状態であるため、嵌合部を突条部に嵌合させる荷重だけが必要で、組付荷重が最小限に抑えられる。また、クリップが所定位置まで嵌合された後は、嵌合部により突条部に付与される弾性力に加え、押圧手段による押圧力が被取付部品に付与されているため、被取付部品の取付面への保持力が高められる。
請求項２に記載したクリップの発明では、押圧アーム部の先端が係止手段の係止孔に挿入されると、押圧手段は湾曲部により下方に付勢する付勢力を有する形態となり、この状態で、嵌合部をスタッドに係合させて押し込み、押圧アーム部及び係止アーム部の下端を被取付部品に押し付けると、係止アーム部が嵌合部との境界部を中心に外方に開き、押圧アーム部の先端が係止孔から離脱して湾曲部の付勢力により被取付部品に勢いよく接触する。つまり、嵌合部が所定位置まで押し込まれた瞬間に、押圧アーム部の先端が係止孔から離脱して被取付部品に接触する際のクリック音やクリック感等により、嵌合部がスタッドの所定位置まで押し込まれたか否かが明瞭になる。
請求項３に記載したクリップの発明では、嵌合部及び押圧手段に、それぞれ所望の弾性力及び押圧力を設定でき、強固に被取付部品が取付面に取り付けられる。 Therefore, in the invention of the clip according to the first aspect, in the state where the pressing means is compressed and contracted by the locking means, the fitting portion is engaged with the projecting portion of the stud and pushed in. When the means is pressed against the mounted part, the pressing means is released from the locking means, and the mounting part is pressed against the mounting surface by the elastic force of the pressing means, and at the same time, the fitting portion is fitted to the protrusion, A part to be attached is attached to the attachment surface. In other words, the assembling load at the time of assembling is a state in which the pressing means is locked to the locking means, so only a load for fitting the fitting portion to the protruding portion is necessary, and the assembling load is minimal. Can be suppressed. In addition, after the clip is fitted to a predetermined position, in addition to the elastic force applied to the protrusion by the fitting portion, the pressing force by the pressing means is applied to the mounted component. The holding force on the mounting surface is increased.
In the invention of the clip according to claim 2, when the tip of the pressing arm portion is inserted into the locking hole of the locking means, the pressing means has a form having a biasing force biased downward by the curved portion, and this state Then, when the fitting part is engaged with the stud and pushed in, and the lower end of the pressing arm part and the locking arm part is pressed against the part to be attached, the locking arm part moves outwards around the boundary part with the fitting part. The tip of the pressing arm part is released from the locking hole and comes into contact with the mounted part vigorously by the urging force of the bending part. In other words, at the moment when the fitting portion is pushed to a predetermined position, the fitting portion is not connected to the stud due to a click sound or a clicking feeling when the tip of the pressing arm portion comes out of the locking hole and comes into contact with the mounted part. It becomes clear whether or not it has been pushed to a predetermined position.
In the invention of the clip according to the third aspect, desired elastic force and pressing force can be set for the fitting portion and the pressing means, respectively, and the mounted component is firmly attached to the mounting surface.

本発明によれば、組み付けの際の組付荷重を低減しつつ、未嵌合状態を発生させることなく、強固に被取付部品を取付面に取り付けるクリップを提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the clip which attaches a to-be-attached component to an attachment surface firmly can be provided, without generating a non-fitting state, reducing the assembly load at the time of an assembly | attachment.

以下、本発明を実施するための最良の形態を図１〜図３に基いて詳細に説明する。
本発明の実施の形態に係るクリップ１は、図１及び図２に示すように、取付面５から被取付部品７の挿通孔７ａを介して突設されるスタッドボルト６のねじ部（突条部）８に係止される複数の係止爪部９を有する嵌合部２と、この嵌合部２の一方の側板２ａの下端から延び被取付部品７を弾性的に押圧する押圧部（押圧手段）３と、嵌合部２の他方の側板２ｂの下端から延び押圧部３を押し縮めた状態で係止する係止部（係止手段）４とから構成されている。
これら嵌合部２、押圧部３及び係止部４は、一枚のバネ鋼板を折り曲げて構成されている。 Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to FIGS.
As shown in FIGS. 1 and 2, the clip 1 according to the embodiment of the present invention includes a threaded portion (protrusion) of a stud bolt 6 that protrudes from an attachment surface 5 through an insertion hole 7 a of an attached component 7. Part) The fitting part 2 having a plurality of locking claws 9 that are locked to the part 8, and a pressing part that extends from the lower end of one side plate 2a of the fitting part 2 and elastically presses the attached part 7 (Pressing means) 3 and a locking portion (locking means) 4 that extends from the lower end of the other side plate 2b of the fitting portion 2 and locks the pressing portion 3 in a compressed state.
The fitting portion 2, the pressing portion 3, and the locking portion 4 are configured by bending a single spring steel plate.

嵌合部２は、図１及び図２に示すように、下方を開放するコ字状に形成されており、両側板２ａ、２ｂのそれぞれには、各側板２ａ、２ｂの略中央を下辺を残して切断した略矩形状の切片を、内方に所定の傾斜角度で折り曲げて、斜め上方に突設させた一対の係止爪部９、９が形成されている。これら一対の係止爪部９、９の先端間の距離Ｌは、スタッドボルト６のねじ溝８’径よりも小さく設定されている。そして、これら一対の係止爪部９、９の先端間にスタッドボルト６が挿入されると、各係止爪部９、９の弾性力により、スタッドボルト６のねじ部８またはねじ溝８’が押圧され、嵌合部２はスタッドボルト６に係止される。 As shown in FIGS. 1 and 2, the fitting portion 2 is formed in a U-shape that opens downward, and each side plate 2 a, 2 b has a substantially central portion of each side plate 2 a, 2 b at the lower side. A pair of locking claws 9 and 9 are formed by bending a substantially rectangular section that is cut off and bending inward at a predetermined inclination angle and projecting obliquely upward. A distance L between the tips of the pair of locking claws 9, 9 is set to be smaller than the diameter of the thread groove 8 'of the stud bolt 6. When the stud bolt 6 is inserted between the ends of the pair of locking claws 9, 9, the threaded portion 8 or the thread groove 8 'of the stud bolt 6 is caused by the elastic force of the locking claws 9, 9. Is pressed, and the fitting portion 2 is locked to the stud bolt 6.

押圧部３は、図１及び図２に示すように、係止部４に係止された状態において、嵌合部２の一方の側板２ａの下端から連続して下方に湾曲する湾曲部１１と、この湾曲部１１から係止部４側に略水平に延びる押圧アーム部１２とから構成されている。この押圧アーム部１２にスタッドボルト６が挿通される挿通孔１３が形成されている。この挿通孔１３は、押圧部３が係止部４に係止された状態で、各係止爪部９、９の先端間の略中央に位置するように形成されている。これら湾曲部１１及び押圧アーム部１２は、その幅が嵌合部２の幅と略同一に設定されており、押圧アーム部１２の先端２１は幅狭に形成され、後述する係止孔１６に挿入できる幅に設定されている。
また、押圧部３が係止部４に係止された状態では、押圧部３は、湾曲部１１の復元力により、その押圧アーム部１２が下方に付勢する付勢力を有する形態となる。この付勢力は、嵌合部２がスタッドボルト６の所定位置まで押し込まれた際、押圧アーム部１２が被取付部品７を適切に押圧するように設定されている。また、バネ鋼板の板厚や湾曲部１１の曲率等を適宜設定することにより、付勢力を調整することができる。なお、押圧部３が係止部４に係止される形態については、後で詳述する。 As shown in FIGS. 1 and 2, the pressing portion 3 includes a bending portion 11 that continuously curves downward from the lower end of one side plate 2 a of the fitting portion 2 in a state where the pressing portion 3 is locked to the locking portion 4. The pressing arm portion 12 extends substantially horizontally from the bending portion 11 to the locking portion 4 side. An insertion hole 13 through which the stud bolt 6 is inserted is formed in the pressing arm portion 12. The insertion hole 13 is formed so as to be positioned approximately at the center between the tips of the locking claws 9 and 9 in a state where the pressing portion 3 is locked to the locking portion 4. The width of the bending portion 11 and the pressing arm portion 12 is set to be substantially the same as the width of the fitting portion 2, and the distal end 21 of the pressing arm portion 12 is formed to be narrow, and a locking hole 16 described later is formed. The width is set to allow insertion.
Further, in a state where the pressing portion 3 is locked to the locking portion 4, the pressing portion 3 is configured to have a biasing force that biases the pressing arm portion 12 downward due to the restoring force of the bending portion 11. This urging force is set so that when the fitting portion 2 is pushed to a predetermined position of the stud bolt 6, the pressing arm portion 12 appropriately presses the attached component 7. Further, the urging force can be adjusted by appropriately setting the plate thickness of the spring steel plate, the curvature of the curved portion 11, and the like. The form in which the pressing portion 3 is locked to the locking portion 4 will be described in detail later.

係止部４は、図１及び図２に示すように、嵌合部２の他方の側板２ｂの下端から連続して嵌合部２と離間する方向に斜め下方に延びる係止アーム部１５と、この係止アーム部１５の下部に設けられ、押圧部３の押圧アーム部１２の先端２１が挿脱される係止孔１６と、係止アーム部１５の下端に形成された外方に湾曲する湾曲部１７とから構成されている。
係止アーム部１５は、嵌合部２の幅と略同一に形成され、嵌合部２との境界部２０を中心に揺動自在に構成されている。また、係止アーム部１５の傾斜角度は、湾曲部１７の外周面及び押圧アーム部１２が被取付部品７に押し付けられた時、係止アーム部１５が境界部２０を中心に外方にスムーズに開くような所定角度θに設定されている。
湾曲部１７は、その外周面が被取付部品７に押し付けられた時、係止アーム部１５が境界部２０を中心に外方にスムーズに開くような所定の曲率に設定されている。また、係止孔１６は、押圧アーム部１２の先端２１が挿通される長孔に形成されている。ここで、押圧部３が係止部４により係止される形態とは、押圧部３の押圧アーム部１２の先端２１が係止アーム部１５の係止孔１６に挿入されて係止された形態であり、この状態において、前述したように、押圧部３に形成された湾曲部１１が押圧アーム部１２を下方に付勢する付勢力を有することになる。 As shown in FIGS. 1 and 2, the locking portion 4 includes a locking arm portion 15 that extends obliquely downward in a direction away from the fitting portion 2 continuously from the lower end of the other side plate 2 b of the fitting portion 2. The locking arm 16 is provided at a lower portion of the pressing arm 3, and the locking arm 16 is formed at the lower end of the locking arm 15. It is comprised from the curved part 17 which does.
The locking arm portion 15 is formed substantially the same as the width of the fitting portion 2 and is configured to be swingable about a boundary portion 20 with the fitting portion 2. Further, the inclination angle of the locking arm portion 15 is such that when the outer peripheral surface of the bending portion 17 and the pressing arm portion 12 are pressed against the mounted part 7, the locking arm portion 15 is smoothly outward with the boundary portion 20 as the center. Is set to a predetermined angle θ that opens at a predetermined angle.
The curved portion 17 is set to have a predetermined curvature such that when the outer peripheral surface thereof is pressed against the mounted part 7, the locking arm portion 15 smoothly opens outwardly around the boundary portion 20. The locking hole 16 is formed as a long hole through which the tip 21 of the pressing arm portion 12 is inserted. Here, the form in which the pressing portion 3 is locked by the locking portion 4 is that the tip 21 of the pressing arm portion 12 of the pressing portion 3 is inserted into the locking hole 16 of the locking arm portion 15 and locked. In this state, as described above, the curved portion 11 formed in the pressing portion 3 has a biasing force that biases the pressing arm portion 12 downward.

さらに、係止アーム部１５の上端と側板２ｂの下端との境界部２０の両端には、湾曲状の切欠部２２、２２が嵌合部２の幅方向中心に向かってそれぞれ形成されている。これら切欠部２２、２２は、境界部２０の幅が係止爪部９の幅と略一致するように設定されている。このように各切欠部２２、２２を設けることにより、これら切欠部２２、２２に応力を集中させると共に、係止アーム部１５だけを揺動し易く構成することができる。その結果、係止アーム部１５が境界部２０を中心に外方に開いた時、側板２ｂが係止アーム部１５に追従して開くことがなく、スタッドボルト６に付与される係止爪部９の弾性力が低減されることはない。 Further, curved notches 22 and 22 are formed at both ends of the boundary portion 20 between the upper end of the locking arm portion 15 and the lower end of the side plate 2 b toward the center in the width direction of the fitting portion 2. These notches 22, 22 are set so that the width of the boundary 20 substantially matches the width of the locking claw 9. Thus, by providing each notch part 22 and 22, stress can be concentrated on these notch parts 22 and 22, and only the latching arm part 15 can be comprised easily. As a result, when the locking arm portion 15 opens outward with the boundary portion 20 as the center, the side plate 2b does not open following the locking arm portion 15 and the locking claw portion applied to the stud bolt 6 The elastic force of 9 is not reduced.

以上のように構成されたクリップ１を使用して、被取付部品７を取付面５に取り付ける手順を図１〜図３に基いて説明する。
まず、押圧部３の押圧アーム部１２の先端２１が係止孔１６に挿入された状態で、嵌合部２の一対の係止爪部９、９を、取付面５から被取付部品７の挿通孔７ａを介して突設されたスタッドボルト６の上端のねじ溝８’に係合させる。次に、嵌合部２を、押圧アーム部１２が被取付部品７に当接し、被取付部品７が取付面５に当接するまで押し込む。すると、一対の係止爪部９、９がスタッドボルト６のねじ部８を乗り越えながら下方にスライドする。さらに連続して嵌合部２を押し込み、湾曲部１７の外周面及び押圧アーム部１２が被取付部品７を介して取付面５に押し付けられると、係止アーム部１５が境界部２０を中心に若干外方（矢印の方向）に開くと同時に、押圧アーム部１２の先端２１が係止孔１６から離脱して、勢いよく被取付部品７に接触する。
そして、被取付部品７が押圧部３の湾曲部１１により取付面５に押圧されると共に、一対の係止爪部９、９がスタッドボルト６のねじ部８に係止されることより、被取付部品７が取付面５に強固に取り付けられることになる。 A procedure for attaching the attached component 7 to the attachment surface 5 using the clip 1 configured as described above will be described with reference to FIGS.
First, in a state where the tip 21 of the pressing arm portion 12 of the pressing portion 3 is inserted into the locking hole 16, the pair of locking claw portions 9, 9 of the fitting portion 2 are moved from the mounting surface 5 to the mounted component 7. The stud bolt 6 projecting through the insertion hole 7a is engaged with the thread groove 8 'at the upper end. Next, the fitting portion 2 is pushed in until the pressing arm portion 12 comes into contact with the attached component 7 and the attached component 7 comes into contact with the attachment surface 5. Then, a pair of latching claw parts 9 and 9 slides downward while getting over the threaded part 8 of the stud bolt 6. Further, when the fitting portion 2 is continuously pushed and the outer peripheral surface of the bending portion 17 and the pressing arm portion 12 are pressed against the mounting surface 5 via the attached component 7, the locking arm portion 15 is centered on the boundary portion 20. At the same time as opening outward (in the direction of the arrow), the tip 21 of the pressing arm portion 12 is detached from the locking hole 16 and vigorously contacts the mounted component 7.
Then, the mounted component 7 is pressed against the mounting surface 5 by the curved portion 11 of the pressing portion 3, and the pair of locking claws 9, 9 are locked to the screw portion 8 of the stud bolt 6. The attachment part 7 is firmly attached to the attachment surface 5.

また、上述した一連の取付手順において、嵌合部２を、押圧アーム部１２の先端２１が係止孔１６から離脱するまで押し込む際、作業者は、一対の係止爪部９、９がスタッドボルト６のねじ部８を乗り越えるに十分な荷重だけで押し込むだけで良い。換言すれば、押圧部３は係止部４により係止されているため、作業者は、嵌合部２を各係止爪部９、９のねじ部８への弾性力に抗するだけの荷重で押し込めば良く、大きな押し込み荷重を必要としない。さらに、嵌合部２が所定位置まで押し込まれた瞬間には、押圧アーム部１２の先端２１が係止孔１６から離脱して被取付部品７に勢いよく接触するので、その際、作業者に伝達されるクリック感やクリック音を確認することで、クリップ１が所定の位置まで押し込まれたことが認識される。 Further, in the above-described series of attachment procedures, when the fitting portion 2 is pushed in until the tip 21 of the pressing arm portion 12 is detached from the locking hole 16, the operator has a pair of locking claw portions 9 and 9 as studs. It is only necessary to push in with a load sufficient to get over the threaded portion 8 of the bolt 6. In other words, since the pressing portion 3 is locked by the locking portion 4, the operator only resists the fitting portion 2 against the elastic force to the screw portion 8 of each locking claw portion 9, 9. It only needs to be pushed in with a load, and a large pushing load is not required. Further, at the moment when the fitting portion 2 is pushed to a predetermined position, the tip 21 of the pressing arm portion 12 is detached from the locking hole 16 and vigorously contacts the mounted component 7. By confirming the transmitted click feeling and click sound, it is recognized that the clip 1 has been pushed to a predetermined position.

以上説明した本発明の実施の形態によれば、嵌合部２をスタッドボルト６に押し込む際には、嵌合部２を各係止爪部９、９のスタッドボルト６への弾性力に抗するだけの荷重で押し込めば良く、組付荷重を最小限に抑えることができ、ワンタッチでの組み付けが可能となる。また、クリップ１が所定位置まで押し込まれた瞬間に、押圧アーム部１２の先端２１が係止孔１６から離脱して、被取付部品７に接触する際のクリック感やクリック音を確認することで、嵌合の完了を認識することができ、未嵌合状態の発生を防ぐことができる。さらに、本発明の実施の形態によれば、クリップ１が所定位置まで押し込まれた後は、押圧部３により被取付部品７を取付面５に押圧すると共に、一対の係止爪部９、９がスタッドボルト６のねじ部８に弾性力を付与してスタッドボルト６を係止しているので、強固に被取付部品７を取付面５に取り付けることができ、被取付部品７の保持力を高めることができる。 According to the embodiment of the present invention described above, when the fitting portion 2 is pushed into the stud bolt 6, the fitting portion 2 is resisted against the elastic force of the locking claws 9, 9 to the stud bolt 6. It is only necessary to push in with a load as much as possible, the assembly load can be minimized, and one-touch assembly is possible. Further, at the moment when the clip 1 is pushed to a predetermined position, the tip 21 of the pressing arm portion 12 is detached from the locking hole 16 and the click feeling and the clicking sound when contacting the attached component 7 are confirmed. The completion of the fitting can be recognized, and the occurrence of the unfitted state can be prevented. Furthermore, according to the embodiment of the present invention, after the clip 1 is pushed to a predetermined position, the attached part 7 is pressed against the attachment surface 5 by the pressing part 3 and the pair of locking claws 9, 9 are pressed. Since the stud bolt 6 is locked by applying an elastic force to the threaded portion 8 of the stud bolt 6, the attached component 7 can be firmly attached to the attachment surface 5, and the holding force of the attached component 7 can be increased. Can be increased.

なお、本実施の形態に係るクリップ１が使用される部位は特に限定されないが、視認性が悪く、作業性を確保できない部位に使用する際特に有効に機能する。例えば、このクリップ１を、自動車の底部に配設されるマフラーからの放熱を遮断するヒートインシュレータを、マフラーを囲うように配設される車体パネルに取り付ける際のクリップとして採用すると特に有効である。この時には、ヒートインシュレータが被取付部品７に相当し、車体パネルが取付面５に相当する。 In addition, although the site | part in which the clip 1 which concerns on this Embodiment is used is not specifically limited, When it uses for the site | part which has bad visibility and cannot ensure workability | operativity, it functions especially. For example, it is particularly effective to employ the clip 1 as a clip for attaching a heat insulator that blocks heat radiation from a muffler disposed at the bottom of an automobile to a vehicle body panel disposed so as to surround the muffler. At this time, the heat insulator corresponds to the mounted component 7, and the vehicle body panel corresponds to the mounting surface 5.

また、本実施の形態に係るクリップ１は、各係止爪部９、９の弾性力や押圧部３の押圧力を高めるために、一枚のバネ鋼板を折り曲げて構成されているが、各係止爪部９、９の弾性力や押圧部３の押圧力がそれほど必要でないクリップの形態として、図示はしないが、クリップ１を樹脂製素材で形成し、嵌合部２を円筒状または角筒状に形成し、またその内部に係止爪部９を全周あるいは部分的に一体成形すると共に、押圧部３を嵌合部２の一方から直線状に延びるように一体成形してもよい。その場合、嵌合部２の他方には幅狭のヒンジ部を介して係止アーム部１５が揺動自在になるように一体成形して、押圧部３を湾曲させてその先端２１を係止孔１６に挿入し、押圧部３を下方に付勢する付勢力を有した形態として、クリップ１を構成することも可能である。 Further, the clip 1 according to the present embodiment is configured by bending a single spring steel plate in order to increase the elastic force of each of the locking claws 9, 9 and the pressing force of the pressing portion 3, Although not shown in the drawings, the clip 1 is formed of a resin material and the fitting portion 2 is formed in a cylindrical shape or a corner shape. It may be formed in a cylindrical shape, and the locking claw portion 9 may be integrally formed inside or partially in the inside thereof, and the pressing portion 3 may be integrally formed so as to extend linearly from one of the fitting portions 2. . In that case, the engaging arm 15 is integrally formed on the other side of the fitting portion 2 via a narrow hinge portion so as to be swingable, the pressing portion 3 is bent, and the tip 21 is locked. It is also possible to configure the clip 1 as a form having an urging force that is inserted into the hole 16 and urges the pressing portion 3 downward.

さらに、本実施の形態に係るクリップ１では、押圧アーム部１２は、その直線状の先端２１が係止孔１６に挿入されて係止される構成であるが、押圧アーム部１２の先端２１は、係止アーム部１５及び押圧アーム部１２が被取付部品７に押し付けられると、係止孔１６から離脱し易くなるように構成され、また平常時には離脱し難くなるように構成する必要がある。そのため、図示はしないが、先端２１に湾曲部や溝部を設け、先端２１を係止孔１６に引っ掛けるように係合させる形態を採用することも可能である。 Furthermore, in the clip 1 according to the present embodiment, the pressing arm portion 12 is configured such that the linear tip 21 is inserted into the locking hole 16 and locked, but the tip 21 of the pressing arm 12 is When the locking arm portion 15 and the pressing arm portion 12 are pressed against the part to be attached 7, the locking arm portion 15 and the pressing arm portion 12 are configured to be easily detached from the locking hole 16, and it is necessary to be configured to be difficult to separate in normal times. Therefore, although not shown, it is also possible to employ a form in which a curved portion or a groove portion is provided at the tip 21 and the tip 21 is engaged so as to be hooked on the locking hole 16.
