Description

本発明は、ピンとグロメットからなるクリップに関し、特にパネル等の取付孔が小さい場合であっても高い軸力（この軸力は、取付孔に対する係合力ないしは引込力と称されることもある。以下同じ）が得られるようにしたクリップに関する。 The present invention relates to a clip composed of a pin and a grommet, and particularly has a high axial force (this axial force may be referred to as an engaging force or a retracting force with respect to the attaching hole even when the attaching hole of a panel or the like is small. The same) as to the clip that was obtained.

図１０は特許文献１のクリップを示している。このクリップは、本体（鍔）２及び本体２に突出された脚部（胴部）１並びに本体２から脚部１に貫通された挿入穴を有したグロメット（雌部材）と、頭部１１及び頭部に突出された軸部１２とを有したピン（雄部材）とからなり、ピンが脚部１の挿入穴に対し軸部１２を途中まで挿入した同（ａ）の仮組付け状態から更なる押込みにより脚部１を拡開状態に切り換える。詳述すると、グロメットは、脚部１がスリット３で区画された複数の切割り片４にて構成され、各切割り片４の下端内向に突出された爪５と、本体の窪み６の内底面に設けられた段差付きの複数の鋸歯形カム７とを有している。ピンは、頭部１１の下面に設けられて鋸歯形カム７に摺接する突起１４と、軸部１２の下端側外周に間隔を保って設けられて爪５を受入れる凹部１５と、各凹部１５の上側にあって突起１４が鋸歯形カム７の下面に摺接しているときに各爪５が乗り上げて切割り片４を拡開した状態に維持する係止***１６と、凹部１５の周側を区画している仕切壁１８とを有している。 FIG. 10 shows the clip of Patent Document 1. This clip includes a main body (flame) 2, a leg portion (trunk portion) 1 protruding from the main body 2, and a grommet (female member) having an insertion hole penetrating from the main body 2 to the leg portion 1, a head portion 11, and From a temporary assembly state of the same (a) in which the shaft (12) is inserted halfway into the insertion hole of the leg (1). The leg 1 is switched to the expanded state by further pushing. More specifically, the grommet includes a plurality of slits 4 in which the leg 1 is divided by slits 3, and a claw 5 protruding inward at the lower end of each slit 4 and a recess 6 in the main body. It has a plurality of serrated cams 7 with steps provided on the bottom surface. The pin is provided on the lower surface of the head portion 11 and slidably contacts the saw-toothed cam 7, a concave portion 15 which is provided on the outer periphery of the lower end side of the shaft portion 12 at a distance to receive the pawl 5, and a concave portion of each concave portion 15. When the projection 14 is on the upper side and the projection 14 is in sliding contact with the lower surface of the saw-toothed cam 7, the claws 5 ride up to keep the slit piece 4 in an expanded state, and the peripheral side of the concave portion 15. It has the partition wall 18 which has divided.

以上のクリップは、ピン側の仕切壁１８と、グロメット側のスリット３の向きを合わせて、軸部１２を脚部１の挿入穴に押し込むと、仕切壁１８がスリット３に入り、かつ各爪５が軸部側の凹部１５に入ることにより両部材が同（ａ）の仮組付け状態になる。この状態で、本体２がパネルＰ1の上面に当接するまで脚部１を各パネルの取付孔に挿入した後、軸部１２が脚部の挿入穴に更に押し込まれると、各切割り片の爪５が軸部側の係止***１６を乗り越えて外方に拡開し、同図（ｂ）のごとく本体２の下面との間に各パネルを重合状態に固定可能となる。 In the above clip, when the shaft portion 12 is pushed into the insertion hole of the leg portion 1 with the partition wall 18 on the pin side and the slit 3 on the grommet side aligned, the partition wall 18 enters the slit 3 and By inserting 5 into the recess 15 on the shaft side, both members are in the temporarily assembled state of the same (a). In this state, after inserting the leg portion 1 into the mounting hole of each panel until the main body 2 comes into contact with the upper surface of the panel P1, when the shaft portion 12 is further pushed into the insertion hole of the leg portion, the claw of each cut piece is formed. 5 overcomes the locking ridge 16 on the shaft side and expands outward, so that the panels can be fixed in a superposed state with the lower surface of the main body 2 as shown in FIG.

上記文献１のクリップでは、パネル等の取付孔の孔径又は孔幅が小さくなると、脚部である切割り片の拡開寸法を大きくし高い軸力を付与し難くなる。これは、脚部ないしは切割り片の拡開寸法が専ら切割り片の下端内向に突出された爪の大きさに制約されるためである。そこで、本発明の目的は、パネル等の取付孔の孔径又は孔幅が小さい場合であっても、脚部の拡開を多少なりとも大きくしてより高い軸力が得られるようにすることにある。他の目的は以下の内容説明のなかで明らかにする。 In the clip of Document 1 described above, when the hole diameter or the hole width of the mounting hole of the panel or the like becomes small, it becomes difficult to apply a high axial force by increasing the expansion dimension of the slit piece that is the leg portion. This is because the expansion dimension of the leg portion or the slit piece is limited only by the size of the claw protruding inward at the lower end of the slit piece. Therefore, an object of the present invention is to increase the expansion of the legs to some extent to obtain a higher axial force even when the hole diameter or the hole width of the mounting hole of the panel or the like is small. is there. Other purposes will be made clear in the following description.

上記目的を達成するため請求項１の発明は、図面を参照して特定すると、本体（１０）及び該本体に突出された脚部（１５）並びに前記本体から前記脚部に貫通された挿入穴（１６）を有したグロメット（１）と、頭部（２０）及び該頭部に突出された軸部（２５）とを有したピン（２）とからなり、前記挿入穴（１６）に対し前記軸部を途中まで挿入したピンとグロメットの仮組付け状態から前記ピンの更なる押入により前記脚部が拡開状態に切り換えられるクリップ（３）であって、前記脚部（１５）に設けられて前記挿入穴に通じている凹部（１８又は１８０）と、前記軸部（２５）に設けられて前記凹部（１８又は１８０）の開口下端に当接して前記脚部を外方へ拡開可能にする突部（２７，２８又は２７０）とを有していることを特徴としている。 In order to achieve the above object, the invention of claim 1 is specified with reference to the drawings, and a main body (10), a leg portion (15) protruding from the main body, and an insertion hole penetrated from the main body to the leg portion. A grommet (1) having (16), and a pin (2) having a head (20) and a shaft (25) protruding from the head, and with respect to the insertion hole (16) A clip (3) for switching the leg portion to an expanded state by further pushing the pin from the temporarily assembled state of the pin and the grommet with the shaft portion inserted halfway, which is provided on the leg portion (15). And the recess (18 or 180) communicating with the insertion hole and the shaft (25) are in contact with the lower end of the opening of the recess (18 or 180) to expand the leg outward. It is characterized in that it has a protrusion (27, 28 or 270).

ここで、対象のクリップは、例えば、第１パネルに単一又は複数の第２パネルを取り付けたり、部材同士を重ね合わせた状態で結合したり、パネル等の被取付部材に装着する場合に好適なものであり、また、形態例のごとくグロメット又はピン側にフック等の機能部を有した態様も含まれる。工夫点は、特に、パネル等の脚部を挿入する取付孔の孔径又は孔幅が小さくなる場合にも、グロメット側脚部の拡開状態において取付孔に対する高い軸力を得られるようにしたものである。 Here, the target clip is suitable when, for example, a single panel or a plurality of second panels are attached to the first panel, the members are combined in a state of being overlapped with each other, or attached to a member to be attached such as a panel. In addition, a mode in which a functional part such as a hook is provided on the grommet or pin side as in the case of the embodiment is also included. A special point is that even when the hole diameter or the hole width of the mounting hole for inserting the leg portion such as the panel becomes small, a high axial force with respect to the mounting hole can be obtained when the leg portion on the grommet side is expanded. Is.

すなわち、従来のクリップにおいて、グロメット側脚部とピン側軸部とは図１０（特許文献１のクリップ）に例示されるごとく脚部に脚部拡開用の脚内側に突出した爪（先端側を内側に絞り込んだ形状）を設けておき、その爪が軸部に当たることで脚部を拡開方向へ変形可能にする。他の構成としては前記爪に代えて脚部の先端内側の肉厚を大きくした構成もある（例えば、特開平７−１１００２１号公報）。 That is, in the conventional clip, the grommet-side leg portion and the pin-side shaft portion are, as illustrated in FIG. 10 (the clip of Patent Document 1), a leg portion that extends inside the leg for expanding the leg portion (tip side). Is provided inward), and its claws hit the shaft to allow the legs to be deformed in the expanding direction. As another configuration, instead of the claw, there is also a configuration in which the thickness of the inside of the tip of the leg is increased (for example, Japanese Patent Laid-Open No. 7-11002).

これに対し、本発明のクリップは、図３及び図４に例示されるごとく軸部に拡開用の突部を形成することで脚部の拡開度合いを大きく設定容易となり、それによってパネル等の取付孔に対する軸力を高くできる。この場合、軸部の突部は、脚部に設けられて挿入穴に通じている凹部の開口下端に当接し、その状態で脚部を拡開状態に維持可能となる。この拡開状態では、取付孔に対し脚部が最大まで拡開されると共にピンの移動が規制されることになる。加えて、このような構成では、脚部拡開用の突部をピンに設定するため、ピン側の成形型に比べ複雑になるグロメット用成形型を多少なりとも簡易化できる利点もある。 On the other hand, in the clip of the present invention, as shown in FIGS. 3 and 4, by forming the expanding projection on the shaft portion, it becomes easy to set the expansion degree of the leg portion to a large degree, thereby facilitating the panel or the like. The axial force of the mounting hole can be increased. In this case, the projection of the shaft portion abuts on the lower end of the opening of the recess provided in the leg portion and communicating with the insertion hole, and in that state, the leg portion can be maintained in the expanded state. In this expanded state, the legs are expanded to the maximum with respect to the mounting holes, and movement of the pins is restricted. In addition, in such a configuration, since the protrusion for expanding the leg is set to the pin, there is an advantage that the grommet forming die, which is more complicated than the forming die on the pin side, can be simplified to some extent.

以上の本発明は、請求項２〜８で特定したように具体化されることがより好ましい。
（ア）図４に示されるごとく前記突部の下端又は前記凹部の開口下端側の一方に案内用の斜面を形成している構成である（請求項２）。この斜面は、下に行くほど挿入穴の中心ないしは脚部の軸芯に近づく形状である。

(A) A slope for guiding is formed on each of the lower end of the protrusion and the lower end of the opening of the recess (claim 3).

（ウ）前記突部を上下の位置をずらした態様で形成している構成である（請求項４）。
（エ）前記脚部は前記挿入穴の下穴を挟んで対向した少なくとも一対の脚片からなり、前記各脚片に前記凹部を形成している構成である（請求項５）。 (C) It is a configuration in which the protrusion is formed in a manner that the vertical position is shifted (claim 4).
(D) The leg portion is composed of at least a pair of leg pieces opposed to each other with the pilot hole of the insertion hole interposed therebetween, and the recess is formed in each of the leg pieces (claim 5 ).

（オ）前記凹部は図１に例示されるごとく前記各脚片の厚み方向に貫通した貫通孔からなる構成である（請求項６）。
（カ）前記凹部は図９に例示されるごとく前記各脚片の側面部の一部を切り欠いた段差からなる構成である（請求項７）。同様に、前記凹部は前記各脚片の両側面部の一部を切り欠いた段差からなる構成である（請求項８）。
（キ）前記本体に設けられて前記挿入穴に露出している係止穴と、前記頭部に設けられた弾性爪部との係合により、前記脚部の拡開状態で前記グロメットに対する前記ピンの不用意な引き抜きを規制する規制手段４を有している構成である（請求項９）。 (E) As shown in FIG. 1, the recess has a through hole penetrating in the thickness direction of each leg (claim 6).
(F) As shown in FIG. 9, the recess has a structure in which a step is formed by cutting out a part of the side surface of each leg (claim 7 ). Similarly, the recess is formed by a step formed by cutting out a part of both side surfaces of each leg (claim 8).
(G) The engagement of the locking hole provided in the main body and exposed to the insertion hole with the elastic claw portion provided in the head portion causes the leg portion to expand with respect to the grommet. It is configured to have a regulation means 4 for regulating the careless pulling out of the pin (claim 9).

請求項１の発明では、グロメット側の脚部に設けられて挿入穴に通じている凹部と、ピン側の軸部に設けられて凹部の開口下端に当接して脚部を外方向へ拡開可能にする突部とを有しているため、パネル等の取付孔が小さい場合であっても、形態例のごとく突部を凹部の一部で逃がしながら（この点は取付孔の孔径又は孔幅に対する脚部の大きさを維持しつつ、突部を相対的に大きく形成可能となる）、最終的に凹部の開口下端に当接して脚部を拡開し、より高い軸力を付与できる。また、このような構成では、脚部拡開用の突部をピンの軸部に設けるため、相対的に複雑となるグロメットの成形型を多少なりとも単純化できるという利点もある。 According to the first aspect of the invention, the leg portion on the grommet side is provided with a recess communicating with the insertion hole, and the shaft portion on the pin side is brought into contact with the opening lower end of the recess to expand the leg portion outward. Even if the mounting hole of the panel or the like is small because it has a protrusion that enables it, the protrusion is allowed to escape in a part of the recess as in the case of the embodiment (this point is the hole diameter of the mounting hole or the hole. The protrusion can be formed relatively large while maintaining the size of the leg portion with respect to the width), and finally the leg portion is expanded by contacting the lower end of the opening of the recessed portion, and a higher axial force can be applied. .. Further, in such a configuration, since the protrusion for expanding the leg is provided on the shaft of the pin, there is an advantage that the relatively complicated grommet mold can be simplified to some extent.

請求項２の発明では、図４に示されるごとく突部の下端又は凹部の開口下端側の少なくとも一方に設けられた案内用の斜面により、軸部の挿入穴への押込みがスムースとなり、その結果、脚部の拡開操作を良好に行うことができる。 According to the second aspect of the invention, as shown in FIG. 4, the guide slope provided on at least one of the lower end of the protrusion and the lower end side of the opening of the recess makes it possible to smoothly press the shaft portion into the insertion hole. It is possible to satisfactorily perform the operation of expanding the legs.

請求項３の発明では、突起の下端及び凹部の開口下端側の両方に案内用の斜面を有しているため、軸部の挿入穴への押入がよりスムースとなり、脚部の拡開操作を一層良好に行うことができる。 According to the third aspect of the invention, since the guide slopes are provided on both the lower end of the protrusion and the lower end side of the opening of the recess, the shaft portion can be pushed into the insertion hole more smoothly, and the leg portion can be expanded. It can be performed even better.

請求項４の発明では、突部を上下の位置をずらして形成しているため、軸部の挿入穴への押入力が分散され、それにより脚部を拡開状態に切り換える際の軸部の押圧力を低減でき、作業性も改善できる。 In the invention of claim 4, since the protrusions are formed by shifting the vertical position, the pushing force to the insertion holes of the shaft portion is dispersed, whereby the shaft portion of the shaft portion when the leg portion is switched to the expanded state is dispersed. The pressing force can be reduced and workability can be improved.

請求項５の発明では、脚部が挿入穴の下穴を挟んで対向した少なくとも一対の脚片からなり、各脚片に凹部を形成しているため、凹部及び突部の位置が簡明となり成形精度を向上し、それによって突部が凹部の開口下端に確実に当接可能となる。 In the invention of claim 5, the leg portion is composed of at least a pair of leg pieces facing each other with the pilot hole of the insertion hole sandwiched therebetween, and the concave portion is formed in each leg piece. The accuracy is improved so that the protrusion can surely contact the lower end of the opening of the recess.

請求項６の発明では、凹部が各脚片の厚み方向に貫通した貫通孔であるため、成形容易となりグロメット側の成形型を簡略化したり凹部の精度を向上できる。 In the invention of claim 6, since the recess is a through hole penetrating in the thickness direction of each leg piece, the molding is facilitated, the molding die on the grommet side can be simplified, and the accuracy of the recess can be improved.

請求項７の発明では、凹部が各脚片の側面部の一部を切り欠いた段差であるため、請求項６に比べグロメット側の成形型を一層簡略化できる。また、請求項８の発明では、凹部が各脚片の両側面部の一部を切り欠いた段差であるため、請求項５に比べより確実な拡開とグロメット側の成形型を更に一層簡略化したり凹部の精度をより向上できる。 In the invention of claim 7, since the recess is a step formed by cutting out a part of the side surface of each leg piece, the molding die on the grommet side can be further simplified as compared with claim 6. Further, in the invention of claim 8, since the concave portion is a step formed by cutting out a part of both side surfaces of each leg piece, more reliable expansion and simplification of the molding die on the grommet side than in claim 5 are achieved. The accuracy of the concave portion can be further improved.

請求項９の発明では、規制手段がグロメット側の本体内の係止穴と、ピン側の頭部の弾性爪部との係合により、グロメットに対するピンの不用意な引き抜きを規制する。この規制手段では、軸部側突部が本体側凹部の開口下端に当接して脚部を外方向へ拡開したときに、ピン側の弾性爪部が本体側係止穴に係合するが、その係合時に弾性爪部のクリック感が得られると共に、係止穴と爪部の係合が本体内であるため係合状態を確実に維持可能となる。 In the invention of claim 9, the regulating means regulates the careless pulling-out of the pin with respect to the grommet by the engagement of the locking hole in the main body on the grommet side with the elastic claw portion of the head portion on the pin side. In this restricting means, when the shaft side projection abuts the lower end of the opening of the main body side recess to expand the leg portion outward, the pin side elastic claw portion engages with the main body side locking hole. A click feeling of the elastic claw portion is obtained at the time of the engagement, and the engagement state between the engagement hole and the claw portion can be surely maintained because it is within the main body.

It is the same as the conventional one in that the leg portion 15 is switched to the expanded state by further pushing the pin 2.

主な要部は、脚部１５の挿入穴１６に通じている凹部である貫通孔１８と、軸部２５に設けられて貫通孔１８の開口下端１８ｂ（図４のごとく貫通孔１８の内側にある開口下端１８ｂ）に当接して脚部１５を外方向へ拡開可能にする突部２７，２８とを有している点、突部２７，２８の下端又は／及び貫通孔１８の開口下端１８ｂ側に案内用の斜面２７ａ，２８ａ又は／及び１８ａを形成している点、軸部２５が略板状をなし、該板状の前後面に突起２７，２８を上下の位置をずらした態様で形成している点、脚部１５が挿入穴１６を挟んで対向した一対の脚片１７，１７からなる点、軸部２５に設けられた仮組付け用爪２９及びその上側の爪２９ａを有している点と、グロメット１に対るピン２の不用意な引き抜きを規制する規制手段４を有している点とにある。以下、これらの構成を明らかにする。 Main parts are a through hole 18 which is a recess communicating with the insertion hole 16 of the leg portion 15, and an opening lower end 18b of the through hole 18 provided in the shaft portion 25 (inside the through hole 18 as shown in FIG. 4). And a projection 27, 28 that abuts against a certain opening lower end 18b) to allow the leg 15 to expand outward, the lower end of the projection 27, 28 and/or the lower opening end of the through hole 18. A point in which guide slopes 27a, 28a or/and 18a are formed on the 18b side, the shaft portion 25 has a substantially plate-like shape, and the projections 27, 28 are vertically displaced on the plate-like front and rear surfaces. The point where the leg portion 15 is composed of a pair of leg pieces 17, 17 facing each other with the insertion hole 16 in between, the temporary assembly nail 29 provided on the shaft portion 25 and the upper nail 29a. The point is that it has, and the point that it has a regulation means 4 that regulates the careless pulling out of the pin 2 with respect to the grommet 1. Hereinafter, these configurations will be clarified.

まず、図１〜図６において、グロメットの本体１０は、台座１１と両側壁１２，１２及び引っ掛け用フック１３とからなり、中央部に前後貫通した略矩形の開口１４を有している。台座１１は、内側が矩形の窪み部になっており、該窪み部の底壁１１ａから脚部１５に向けて挿入穴１６を貫通形成している。該窪み部は、内側に張り出した対向内側面１１ｂと、各内側面１１ｂの後面側の角部に設けられた係止穴１１ｃと、前後内面に対向して設けられた縦方向の案内溝１１ｄとを有している。 First, in FIGS. 1 to 6, a main body 10 of the grommet is composed of a pedestal 11, side walls 12 and 12, and a hook 13 for hooking, and has a substantially rectangular opening 14 penetrating in the front-rear direction in a central portion. The pedestal 11 has a rectangular recess inside, and an insertion hole 16 is formed through the bottom wall 11 a of the recess toward the leg 15. The recessed portion is a facing inner side surface 11b projecting inward, a locking hole 11c provided at a corner on the rear surface side of each inner side surface 11b, and a vertical guide groove 11d provided so as to face the front and rear inner surface. And have.

底壁１１ａの下面には、中央部に突出された脚部１５と、脚部１５を挟んだ左右に突出された差込片１９，１９と、各差込片１９の外側に比較的深く窪んだ凹所１１ｅ，１１ｅとが設けられている。フック１３は、図３（ｂ）から推察されるごとく同図のクリップ３を天地逆転した状態で袋や紐等の部材９を引っ掛ける箇所である。このフック１３では、図６（ｂ）のごとく後面が上記窪み部の真上部分と連通する段差１３ａに形成されている。段差１３は、後述するピンの軸部２５を挿入穴１６へ真っ直ぐに差込可能にする。 On the lower surface of the bottom wall 11a, the leg portion 15 protruding in the central portion, the insertion pieces 19 and 19 protruding left and right sandwiching the leg portion 15, and a relatively deep recess on the outside of each insertion piece 19 are formed. The recesses 11e and 11e are provided. The hook 13 is a portion for hooking a member 9 such as a bag or a string with the clip 3 shown in FIG. 3B turned upside down as inferred from FIG. 3B. As shown in FIG. 6B, the hook 13 has a rear surface formed with a step 13a communicating with the portion directly above the recess. The step 13 enables the pin shaft portion 25 described later to be inserted straight into the insertion hole 16.

脚部１５は、挿通穴１６の下穴１６ａを挟んで対向した一対の脚片１７からなる。各脚片１７には、厚み方向に同軸線上に貫通した上下に長い矩形の貫通孔１８が設けられている。各貫通孔１８は対応する案内溝１１ｄから延びた状態となっている。また、各脚片１７のうち、各貫通孔１８を区画している内側の開口下端側が下に行くに従って次第に中央よりないしは挿通穴１６の軸芯側に傾いた斜面１８ａに形成されている。なお、前記下穴１６ａは脚片１７同士の間の空間ないしは間隔である。 The leg portion 15 is composed of a pair of leg pieces 17 facing each other with the prepared hole 16a of the insertion hole 16 interposed therebetween. Each leg piece 17 is provided with a vertically long rectangular through hole 18 penetrating coaxially in the thickness direction. Each through hole 18 is in a state of extending from the corresponding guide groove 11d. In addition, of the leg pieces 17, an inner opening lower end side that defines each through hole 18 is formed on a sloped surface 18a that is gradually inclined from the center or toward the axial center side of the insertion hole 16 as it goes downward. The pilot hole 16a is a space or space between the leg pieces 17.

各差込片１９は、脚部１５を挟んで対向しており、パネルないしは被取付部材の矩形の取付孔に対し脚片１７と共に挿入されることで、クリップ３を安定した固定状態に保つ。但し、差込片１９は省略してもクリップ３が取付孔に回動不能に固定される。各凹所１１ｅには、図５（ｃ）のごとく脚部１５よりでかつ後面側の角部を***１１ｆにより前記窪み部に貫通している。この***１１ｆは、前記係止穴１１ｃを作る際の型抜き用の穴である。 The insertion pieces 19 are opposed to each other with the leg portion 15 sandwiched therebetween, and are inserted together with the leg piece 17 into a rectangular attachment hole of a panel or a member to be attached, thereby keeping the clip 3 in a stable fixed state. However, even if the insertion piece 19 is omitted, the clip 3 is non-rotatably fixed in the mounting hole. As shown in FIG. 5C, each of the recesses 11e has a corner portion on the rear surface side of the leg portion 15 penetrating the recessed portion by a small hole 11f. This small hole 11f is a hole for die cutting when making the locking hole 11c.

これに対し、ピン２は、図３（ｂ）のごとくグロメット１を貫通する長さとなっている。頭部２０は、段差１３ａ及び開口１４にほぼ収まる略湾曲状の上部２１と、上記窪み部に収まる下部２２からなる。上部２１には、前面に位置し上側に突出して段差１３ａに当接する小さな凸部２１ａと、下部２２との境界部分を欠肉させた横溝２１ｂとが設けられている。符号２１ｃは上部２１の両側面に設けられた欠肉用の空洞である。なお、横溝２１ｂ及び空洞２１ｃは省略可能である。 On the other hand, the pin 2 has a length that penetrates the grommet 1 as shown in FIG. The head 20 is composed of a substantially curved upper portion 21 that fits in the step 13a and the opening 14, and a lower portion 22 that fits in the recess. The upper portion 21 is provided with a small convex portion 21a located on the front surface, protruding upward, and abutting the step 13a, and a lateral groove 21b having a boundary portion with the lower portion 22 lacking in thickness. Reference numeral 21c is a hollow for hollowing, which is provided on both side surfaces of the upper portion 21. The lateral groove 21b and the cavity 21c can be omitted.

下部２２は、上部２１に比べて上下寸法が上記台座１１に対応して前面に比べ後面を長く形成しており、図７及び図８のごとく前面側の左右中間に設けられたガイド突起２６と、後面の両側に設けられた弾性爪部２４とを有している。 The lower portion 22 has a rear surface longer than the front surface in the vertical dimension corresponding to the pedestal 11 as compared with the upper portion 21, and as shown in FIGS. , And elastic claw portions 24 provided on both sides of the rear surface.

ガイド突起２６は、案内溝１１ｄに摺動自在に嵌合する箇所であり、軸部２５の上側まで延び、傾斜部２６ａを介在して後述する突部２７に接続されている。各弾性爪部２４は、図８（ａ）のごとく対応側面の後側に設けられた窪み２３ａと、図７（ｃ）のごとく後面に位置し対応側面の手前に設けられて窪み２３ａに連通した窪み２３ｂとにより区画された弾性片であり、該弾性片の上下略中間に側方に向けて突出された爪を有している。この弾性爪部２４は上記係止穴１１ｃとで規制手段４を構成している。 The guide projection 26 is a portion slidably fitted in the guide groove 11d, extends to the upper side of the shaft portion 25, and is connected to a projection portion 27 described later with an inclined portion 26a interposed therebetween. Each elastic claw portion 24 communicates with the depression 23a provided on the rear side of the corresponding side surface as shown in FIG. 8A and the depression 23a provided on the rear surface as shown in FIG. 7C and before the corresponding side surface. The elastic piece is defined by the recess 23b, and has a claw projecting laterally at approximately the middle of the upper and lower sides of the elastic piece. The elastic claw portion 24 constitutes the regulating means 4 together with the locking hole 11c.

軸部２５は、上記脚片１７同士の間の下穴１６ａに差し込まれる板厚に形成されていると共に、下側２５ａが少し薄く形成されている。また、軸部２５は、前後面に設けられた脚片拡開用の突部２７，２８と、前面の下両側に設けられてグロメット１に対するピン２の仮組み付け用爪２９及びその上側の爪２９ａとを有している。 The shaft portion 25 is formed to have a plate thickness that can be inserted into the prepared hole 16a between the leg pieces 17, and the lower side 25a is formed to be slightly thin. The shaft portion 25 includes projections 27 and 28 for expanding the leg pieces provided on the front and rear surfaces, a claw 29 for temporarily assembling the pin 2 to the grommet 1 and claws on the upper side thereof, which are provided on both lower sides of the front surface. 29a.

突部２７と２８は、高さ寸法がほぼ等しい点と、下端部が下に行くほど次第に低くなる斜面２７ａ，２８ａとなっている点で同じである。但し、両者は、突部２７が軸部下端の少し手前まで延びているのに対し突部２８が軸部下端まで延びている。また、突部２７は、上部分が幅細に形成されて上記傾斜部２６ａに接続されている。符号２７ｂはその幅細部である。突部２８は軸部２５の上下略中間から下端まで延びている。爪２９と爪２９ａは階段状に設けられている。 The protrusions 27 and 28 are the same in that they have substantially the same height dimension and that the lower end portions thereof have slopes 27a and 28a that gradually decrease as they go downward. However, in both of them, the protrusion 27 extends slightly before the lower end of the shaft portion, whereas the protrusion 28 extends to the lower end of the shaft portion. The upper portion of the protrusion 27 has a narrow width and is connected to the inclined portion 26a. Reference numeral 27b is a width detail thereof. The protrusion 28 extends from substantially the middle of the shaft 25 up and down to the lower end. The claw 29 and the claw 29a are provided stepwise.

（作動）以下、以上のクリップ３の主な作動を図２〜図４を参照し明らかにする。なお、図２〜図４において、この例では、符号６が自動車の室内側のインナーパネルであり、符号５がサンシェードである。また、このクリップ３は、サンシェード用フックとして設計されている。但し、このクリップ３は、フック１３及びそれと関連する部分を省いて、取付用クリップとして構成できるものである。 (Operation) Hereinafter, the main operation of the clip 3 will be clarified with reference to FIGS. 2 to 4, in this example, reference numeral 6 is an inner panel on the indoor side of the automobile, and reference numeral 5 is a sunshade. Further, the clip 3 is designed as a sun shade hook. However, the clip 3 can be configured as a mounting clip by omitting the hook 13 and the portion related thereto.

（ア）クリップ３は、グロメット１とピン２が分離されていると扱い難いことから、通常は図３及び図４の各（ａ）のごとくピン２をグロメット１に仮組み付け状態ないしは仮止め状態で取り扱われたり組立工程に投入される。この操作では、図２のごとくピン２がグロメット１の挿入穴１６に対し各案内溝１１ｄに対応する突部２７，２８を嵌合した状態で下向きに押圧される。すると、ピン２は、軸部の下両側の爪２９が挿入穴１６の穴内面を圧接しながら底壁１１ａの下面側へ通過し、以後は爪２９が底壁１１ａに引っ掛かるため簡単には引き抜かれない。換言すると、この構成では、ピン２が仮組み付け状態でグロメットの挿入穴１６から引き抜き方向の加重を受けると、各爪９が底壁１１ａの下面に当たって抜け止めされる。なお、爪９ａは、爪９との間に底壁１１ａを上下から挟み、それによりピン２の仮組み付け状態を確実に保たれるよう機能する。 (A) Since the clip 3 is difficult to handle when the grommet 1 and the pin 2 are separated, normally, the pin 2 is temporarily assembled or temporarily fixed to the grommet 1 as shown in (a) of FIGS. 3 and 4. It is handled in and put into the assembly process. In this operation, as shown in FIG. 2, the pin 2 is pressed downward with the protrusions 27 and 28 corresponding to the guide grooves 11d fitted in the insertion holes 16 of the grommet 1. Then, the pin 2 passes through to the lower surface side of the bottom wall 11a while the claws 29 on both lower sides of the shaft portion press-contact the inner surface of the insertion hole 16, and thereafter, the claws 29 are caught on the bottom wall 11a, so that the pin 2 is easily pulled. Can't be pulled out. In other words, in this configuration, when the pin 2 is temporarily assembled and receives a load in the pulling-out direction from the insertion hole 16 of the grommet, each claw 9 hits the lower surface of the bottom wall 11a and is prevented from coming off. The claw 9a functions so that the bottom wall 11a is sandwiched between the claw 9 and the claw 9 from above and below so that the temporarily assembled state of the pin 2 can be reliably maintained.

（イ）図３（ｂ）は以上のグロメット１に対するピン２の仮組み付け状態から、ピン２が更に同（ａ）の矢印方向へ押圧されて脚部１５ないしは各脚片１７が突部２７，２８により拡開状態に切り換えられた状態を示している。この場合、ピン２は、まず、突部２７，２８が対応する脚片１７の貫通孔１８に収まった後、ピン２が更に押圧されると、相対的に下側にある突起２８の斜面２８ａが対応する右側脚片１７の貫通孔１８の開口下端１８ｂに当接し、該脚片１７を少しづつ拡開し、その後、突起２８が貫通孔１８の開口下端１８ｂに当接することで該脚片１７が拡開状態となる。また、開口下端１８ｂに対し斜面２８ａから突部２８の直線部に乗り上げると同時、ないしは乗り上げる少し手前で、突起２７の斜面２７ａが対応する左側脚片１７の貫通孔１８の開口下端１８ｂに当接し、該脚片１７を少しづつ拡開し、その後、突起２７が貫通孔１８の開口下端１８ｂに当接することで該脚片１７が拡開状態となる。 (A) In FIG. 3(b), the pin 2 is further pressed in the arrow direction of the same (a) from the above-mentioned provisionally assembled state of the pin 2 to the grommet 1 so that the leg portion 15 or each leg piece 17 is projected. 28 shows a state in which the state is switched to the expanded state by 28. In this case, the pin 2 is first accommodated in the through hole 18 of the corresponding leg piece 17 after the protrusions 27 and 28 are accommodated, and then when the pin 2 is further pressed, the sloped surface 28a of the protrusion 28 located relatively below. Abuts on the lower end 18b of the opening of the through hole 18 of the corresponding right leg piece 17, expands the leg piece 17 little by little, and then the protrusion 28 abuts on the lower end 18b of the opening of the through hole 18, thereby 17 is in the expanded state. Also, at the same time when the sloped surface 28a rides on the straight portion of the protrusion 28 with respect to the opening lower end 18b, or slightly before the riding, the sloped surface 27a of the protrusion 27 abuts the corresponding opening lower end 18b of the through hole 18 of the left leg 17. The leg pieces 17 are opened little by little, and then the projections 27 are brought into contact with the opening lower ends 18b of the through holes 18, whereby the leg pieces 17 are opened.

（ウ）また、ピン２が図４（ａ）の状態から同（ｂ）の拡開状態に切り換えられると同時に、上記規制手段４を構成している頭部両側の弾性爪部２４が上記した台座１１の内側の窪み部から対応する係止穴１１ｃに係合する。この係合により、作業者は係合時のクリック感により、拡開完了を認識できると共に、ピン２はグロメット１に対し結合されて不用意に抜けなくなる。 (C) Further, the pin 2 is switched from the state shown in FIG. 4(a) to the expanded state shown in FIG. 4(b), and at the same time, the elastic claw portions 24 on both sides of the head constituting the regulating means 4 are moved to the above-mentioned state. The recesses inside the pedestal 11 are engaged with the corresponding locking holes 11c. By this engagement, the operator can recognize the completion of the expansion by the click feeling at the time of engagement, and the pin 2 is coupled to the grommet 1 so that the pin 2 cannot be accidentally pulled out.

換言すると、図３及び図４の各（ｂ）は、ピン２がグロメット１に対し係合した拡開状態ないしは本止め状態である。この例では、クリップ３が車室内側のインナーパネルである第１パネル５にサンシェード等である第２パネル６を各パネルに設けられた取付孔５ａ，５ｂに挿通された状態で装着される。つまり、クリップ３は、各取付孔５ａ，５ｂに挿通した対のグロメット側の脚片１５がピン軸部側の突部２７，２８で拡開されることで、各パネル５，６をグロメット側台座１１と脚片１５，１５の拡開部との間に挟時した状態で装着される。この装着力ないしは挟時力は、軸部側突起２７，２８が脚片１５，１５に設けられた貫通孔１８の開口下端１８ｂに圧接し、その各脚片１５に対する拡開力ないしは圧接力に比例する。また、この装着状態は、その脚片１５の拡開力ないしは圧接力と、規制手段４である弾性爪部２４と係止穴１１ｃの係合力とにより維持される。弾性爪部４と係止穴１１ｃの係合では、ピン側の弾性爪部２４がグロメットの台座１１内の窪み部内から横穴である係止穴１１ｃに係合されるため外力の影響を受けず、弾性爪部２４が係止穴１１ｃに弾性係合された後は係合解除され難くなる。 In other words, each (b) of FIGS. 3 and 4 is in the expanded state or the final stopped state in which the pin 2 is engaged with the grommet 1. In this example, the clip 3 is mounted in a state in which a second panel 6 such as a sunshade is inserted in a first panel 5 which is an inner panel on the vehicle interior side and is inserted through mounting holes 5a and 5b provided in each panel. That is, in the clip 3, the pair of grommet-side leg pieces 15 that are inserted into the mounting holes 5a and 5b are expanded by the protrusions 27 and 28 on the pin shaft portion side, so that the panels 5 and 6 are grommet-sided. It is mounted in a state of being sandwiched between the pedestal 11 and the expanded portions of the leg pieces 15, 15. This mounting force or pinching force causes the shaft-side protrusions 27, 28 to come into pressure contact with the lower end 18b of the opening of the through hole 18 provided in the leg pieces 15, 15 so as to be expanded force or pressure contact force with respect to each leg piece 15. Proportional. Further, this mounted state is maintained by the expanding force or pressure contact force of the leg piece 15 and the engaging force of the elastic claw portion 24 which is the restricting means 4 and the locking hole 11c. When the elastic claw portion 4 and the locking hole 11c are engaged, the elastic claw portion 24 on the pin side is engaged with the locking hole 11c, which is a lateral hole, from within the recess in the pedestal 11 of the grommet, and thus is not affected by external force. After the elastic claw portion 24 is elastically engaged with the locking hole 11c, it is difficult to release the engagement.

（エ）以上のクリップ３では、軸部２５に拡開用の突部２７，２８を形成することで脚部１５ないしは対の脚片１７の拡開度合いを大きく設定容易となり、それによってパネル等の取付孔５ａ，６ａに対する高い軸力を得ることも可能となる。すなわち、軸部の突部２７，２８は、脚部１５ないしは対の脚片１７に設けられて挿入穴１６の下穴１６ａに通じている貫通孔（凹部）１８の開口下端１８ｂに当接し、その状態で脚部１５ないしは対の脚片１７を拡開状態に維持可能となる。この拡開状態では、取付孔５ａ，６ａに対し脚部１５ないしは対の脚片１７が最大まで拡開されると共にピン２の移動が規制される。この構造では、パネル等の取付孔５ａ，６ａが小さい場合であっても、突部２７，２８を貫通孔（凹部）１８の一部で逃がしながら、換言すると、取付孔５ａ，６ａの孔径又は孔幅に対する脚部１５ないしは対の脚片１７が大きさを維持しつつ、突部２７，２８を相対的に大きく形成可能となり、最終的に貫通孔（凹部）１８の開口下端１８ｂに当接して脚部１５ないしは対の脚片１７を拡開し、より高い軸力を付与できる。また、このような構成では、脚部拡開用の突部２７，２８をピンの軸部２５に設けるため、相対的に複雑となるグロメット１の成形型を多少なりとも単純化でき、コスト低減も図りやすいという利点もある。 (D) In the clip 3 described above, by forming the protrusions 27 and 28 for expanding on the shaft 25, it becomes easy to set the expanding degree of the leg 15 or the pair of leg pieces 17 to a large degree, and thereby the panel or the like can be set. It is also possible to obtain a high axial force with respect to the mounting holes 5a and 6a. That is, the protrusions 27 and 28 of the shaft portion come into contact with the opening lower end 18b of the through hole (recessed portion) 18 provided in the leg portion 15 or the pair of leg pieces 17 and communicating with the prepared hole 16a of the insertion hole 16, In this state, the leg portion 15 or the pair of leg pieces 17 can be maintained in the expanded state. In this expanded state, the leg 15 or the pair of leg pieces 17 is expanded to the maximum with respect to the mounting holes 5a and 6a, and the movement of the pin 2 is restricted. In this structure, even when the mounting holes 5a, 6a of the panel or the like are small, the protrusions 27, 28 are escaped by a part of the through holes (recesses) 18, in other words, the diameter of the mounting holes 5a, 6a or The projections 27 and 28 can be formed relatively large while the size of the leg portion 15 or the pair of leg pieces 17 with respect to the hole width is maintained, and finally, the protrusion portions 27 and 28 come into contact with the opening lower end 18b of the through hole (recess) 18. The leg portion 15 or the pair of leg pieces 17 can be expanded to give a higher axial force. Further, in such a configuration, since the protrusions 27 and 28 for expanding the legs are provided on the shaft portion 25 of the pin, the relatively complicated molding die of the grommet 1 can be simplified to some extent, and the cost can be reduced. There is also an advantage that it is easy to plan.

（変形例）図９は以上のクリップを変形した一例を示している。この変形例では、上記したグロメット側脚部１５の貫通孔ないしは凹部と、ピン側軸部２５の突部の形成箇所などを変更している。この説明では、重複記載を極力避けるため上記形態と同じ部位ないしは作用的に同じ部位に同一符号を付し、変更点を明らかにする。 (Modification) FIG. 9 shows an example in which the above clip is modified. In this modified example, the through hole or the recess of the grommet side leg 15 and the location where the protrusion of the pin side shaft portion 25 is formed are changed. In this description, in order to avoid duplicated description as much as possible, the same parts as those in the above-mentioned embodiment or the same parts as in operation are denoted by the same reference numerals to clarify the changed points.

図９において、グロメット１の脚部１５は、上記形態と同じく挿通穴１６の下穴１６ａを挟んで対向した一対の脚片１７からなる。各脚片１７には、両側面部の一部を略Ｌ形に切り欠いた段差１８０が設けられている。この段差１８０には、段差の水平部が上記形態の開口下端１８ｂに相当する開口下端１８０ｂとなっている。 In FIG. 9, the leg portion 15 of the grommet 1 is composed of a pair of leg pieces 17 that are opposed to each other with the prepared hole 16a of the insertion hole 16 interposed therebetween as in the above embodiment. Each leg piece 17 is provided with a step 180 in which a part of both side surfaces is cut out into a substantially L shape. In this step 180, the horizontal part of the step is an opening lower end 180b corresponding to the opening lower end 18b in the above-described embodiment.

一方、ピン２の軸部２５は、上記形態と同じく脚片１７同士の間の下穴１６ａに差し込まれる板厚に形成されていると共に、下側２５ａが少し薄く形成されている。そして、軸部２５には、前後面にあって、両側に沿って脚片拡開用の突部２７０，２８０（図面上は突部２７０だけ図示され、突部２８０が見えないため省略されている）と、下両側面に設けられてグロメット１に対するピン２の仮組み付け用爪２９０及びその上側の爪２９０ａとを有している。 On the other hand, the shaft portion 25 of the pin 2 is formed to have a plate thickness that can be inserted into the prepared hole 16a between the leg pieces 17 as in the above embodiment, and the lower side 25a is formed to be slightly thin. The shaft portion 25 has projections 270, 280 on the front and rear surfaces for expanding the leg pieces along both sides (only the projection 270 is shown in the drawing, and the projection 280 is not visible, so it is omitted). And a claw 290 for temporarily assembling the pin 2 with respect to the grommet 1 and a claw 290a on the upper side thereof, which are provided on both lower side surfaces.

なお、突起２７０と２８０は、形態例の突部２７，２８と同じく高さ寸法がほぼ等しい点と、下端部が下に行くほど次第に低くなる斜面２７０ａ，２８０ａとなっている。両者は、突部２７０が軸部下端の少し手前まで延びているのに対し、不図示の突部２８０が軸部下端まで延びている。また、爪２９０と２９０ａは形態例の爪２９，２９ａに対応している。但し、形態例の爪２９は底壁１１ａの挿通穴１６を区画している下面のうち前後の下面部分に抜け止めされるのに対し、爪２９０は底壁１１ａの挿通穴１６を区画している下面のうち左右の下面部分に抜け止めされる。 The protrusions 270 and 280 are similar in height to the protrusions 27 and 28 of the embodiment, and have slopes 270a and 280a whose lower end portions are gradually lowered. In both of them, the protrusion 270 extends slightly before the lower end of the shaft portion, while the protrusion 280 (not shown) extends to the lower end of the shaft portion. Further, the claws 290 and 290a correspond to the claws 29 and 29a of the embodiment. However, the claw 29 of the embodiment example is prevented from coming off from the front and rear lower surfaces of the lower surface that defines the insertion hole 16 of the bottom wall 11a, whereas the claw 290 defines the insertion hole 16 of the bottom wall 11a. The left and right lower surfaces of the lower surface are prevented from coming off.

そして、変形例のクリップは、同図のグロメット１に対するピン２の仮組み付け状態から、ピン２が更に下向きに押圧操作されると、各脚片１７が突部２７０，２８０により拡開状態に切り換えられる。この作動は形態例と同様である。すなわち、ピン２は、まず、突部２７０，２８０が対応する脚片１７の段差１８０，１８０に収まった後、ピン２が更に押圧されると、相対的に下側にある不図示の突起２８０の斜面が対応する段差１８０の開口下端１８０ｂに当接し、該脚片１７を少しづつ拡開し、その後、不図示の突起２８０が段差１８０の開口下端１８０ｂに当接することで該脚片１７が拡開状態となる。 Then, in the clip of the modified example, when the pin 2 is pressed further downward from the temporarily assembled state of the pin 2 with respect to the grommet 1 in the same figure, each leg piece 17 is switched to the expanded state by the protrusions 270 and 280. To be This operation is similar to that of the embodiment. That is, the pin 2 first fits into the step 180, 180 of the corresponding leg piece 17 by the protrusion 270, 280, and then, when the pin 2 is further pressed, the protrusion 280 (not shown) relatively below. The sloped surface of the leg contacts the lower end 180b of the opening of the corresponding step 180, expands the leg piece 17 little by little, and then the projection 280 (not shown) abuts the lower end 180b of the opening of the step 180 so that the leg piece 17 moves. Expanded state.

なお、以上のクリップは、各請求項で特定される構成を備えておればよく、細部はこの形態例や変形例を参考にして更に変更したり展開可能なものである。その一例として、脚部１５の脚片１７に設けた貫通孔１８に代えて、脚片の内面に挿通穴１６ａに通じている凹部を設ける構成でもよい。この場合は、軸部２５の突起２７，２８がその凹部の開口下縁に当接して脚部を外方向へ拡開可能にする。また、脚部１５の脚片１７は、一対ではなく二対の脚片又は３つの脚片でもよい。全体の形状は、グロメット側本体１０の両側壁１２及びフック１３を省き、かつピン側頭部２０の両側壁１２及びフック１３と嵌合する部分を省略する構成、つまり単純な取付用クリップに簡略化してもよい。更に、パネルや被取付部材の取付孔に対する差込片１９を省略したり、取付孔を略矩形から楕円や円形に変更しても差し支えない。 The clip described above may be provided with the configuration specified in each claim, and the details can be further modified or expanded with reference to the form example and the modified example. As an example thereof, instead of the through hole 18 provided in the leg piece 17 of the leg portion 15, a configuration may be used in which a recess communicating with the insertion hole 16a is provided on the inner surface of the leg piece. In this case, the protrusions 27 and 28 of the shaft portion 25 come into contact with the lower edge of the opening of the concave portion to allow the leg portion to expand outward. The leg pieces 17 of the leg portion 15 may be two pairs of leg pieces or three leg pieces instead of one pair. The overall shape is a structure in which both side walls 12 and hooks 13 of the grommet side main body 10 are omitted, and parts which are fitted with both side walls 12 and hooks 13 of the pin side head 20 are omitted, that is, a simple mounting clip. May be turned into. Furthermore, the insertion piece 19 for the mounting hole of the panel or the member to be mounted may be omitted, or the mounting hole may be changed from a substantially rectangular shape to an oval or circular shape.
