Abstract

PROBLEM TO BE SOLVED: To suitably constitute a resin plug body having a function capable of easily inserting the plug body into a hole of an attachment target and preventing the plug body from being easily detached after insertion into the hole.SOLUTION: The resin plug body includes a head part 1, a shaft part 2 extended from the head part 1 and an engagement part 3 connected to the head part 1 or the shaft part 2 through an elastic deformation part 4 so as to be moved in a direction crossing with an axis x of the shaft part 2 on the side of the shaft part 2. When a portion other than the head part 1 is inserted into a hole Na formed on an attachment target N, the engagement part 3 is engaged with an engaged part Nb in the hole Na by elastic force of the elastic deformation part 4. The shaft part 2 includes a guide part 22 which when force of a direction for detaching the portion other than the head part 1 from the hole Na is applied, guides the engagement part 3 in a direction of pressing the engagement part 3 to an inner surface of the hole Na while being in contact with a guided part 34 of the engagement part 3.

Description

この発明は、取付対象に形成された孔に頭部以外の部分を挿入可能で且つこの挿入によりこの孔側に掛合可能に構成されて、かかる掛合により前記取付対象に取り付け用いられる樹脂製プラグ体の改良に関する。   The present invention is configured so that a portion other than the head can be inserted into a hole formed in the attachment target and can be engaged with the hole side by this insertion, and the resin plug body used for attachment to the attachment object by such engagement. Regarding improvements.

頭部とアンカー状部を有し、アンカー状部の弾性変形によりこのアンカー状部のネジ孔への挿入を許容させると共に、この挿入停止位置でのアンカー状部の弾性復帰によりこのアンカー状部の先端をネジ孔の雌ネジ部に掛合させるようにしてなるクリップがある。(特許文献1参照)かかるクリップにあっては、前記アンカー状部を弾性変形し難くすればネジ孔とアンカー状部との掛合状態は強固となるが、単純にアンカー状部を弾性変形し難くするとこれをネジ孔へ挿入するときの挿入力を大きくさせてしまうため、前記掛合状態を強固とするのに限界がある。   It has a head and an anchor-like part, and allows the anchor-like part to be inserted into the screw hole by elastic deformation of the anchor-like part, and the anchor-like part of the anchor-like part by elastic return of the anchor-like part at the insertion stop position. There is a clip that has a tip engaged with a female screw portion of a screw hole. (See Patent Document 1) In such a clip, if the anchor-like portion is hardly elastically deformed, the engagement state between the screw hole and the anchor-like portion becomes strong, but it is difficult to simply elastically deform the anchor-like portion. Then, since the insertion force when inserting this into a screw hole will be enlarged, there exists a limit in strengthening the said engagement state.

この発明が解決しようとする主たる問題点は、取付対象の孔に挿入し易く且つこの挿入後は抜け難い機能をもった樹脂製プラグ体を適切に構成できるようにする点にある。   The main problem to be solved by the present invention is to make it possible to appropriately configure a resin plug body having a function that is easy to insert into a hole to be attached and difficult to come out after this insertion.

前記課題を達成するために、この発明にあっては、樹脂製プラグ体を、頭部と、この頭部から延出される軸部と、この軸部の側方にあってこの軸部の軸線に交叉する向きの移動可能に弾性変形部を介して前記頭部又は軸部に連接された掛合部とを有し、前記頭部以外の部分を取付対象に形成された孔に挿入したときにこの孔内の被掛合部に前記掛合部を前記弾性変形部の弾性力により掛合させるようになっていると共に、
前記軸部に、前記頭部以外の部分を前記孔から抜き出す向きの力が作用されたときに、前記掛合部の被案内部に接して前記孔の内面に押しつける向きにこの掛合部を案内する案内部が備えられているものとした。
In order to achieve the above object, according to the present invention, the resin plug body includes a head portion, a shaft portion extending from the head portion, a side of the shaft portion, and an axis of the shaft portion. And a hook part connected to the head part or the shaft part through an elastically deformable part so as to be movable in the direction of crossing, and when a part other than the head part is inserted into a hole formed in the attachment target The hooked portion is hooked to the hooked portion in the hole by the elastic force of the elastically deformable portion, and
When a force is applied to the shaft portion so as to pull out a portion other than the head from the hole, the hook portion is guided in a direction to contact the guided portion of the hook portion and press against the inner surface of the hole. It was assumed that a guide was provided.

前記取付対象の孔に頭部以外の部分を挿入・掛合させた状態から、プラグ体にこの頭部以外の部分を前記孔から抜き出す向きの力が作用されると、案内部と被案内部の協働によって、掛合部は弾性変形部を変形させながら被掛合部との掛合を解く向きと逆の前記孔の内面に押しつけられる向きに案内される。これにより取付対象の孔に対するプラグ体の取り付け状態は安定的に維持される。すなわち、かかるプラグ体は、取付対象の孔に挿入し易く構成できる一方で、この孔より抜け難く構成することができる。   From the state in which the part other than the head is inserted and engaged with the hole to be attached, when a force is applied to the plug body in a direction to extract the part other than the head from the hole, the guide part and the guided part By the cooperation, the engaging part is guided in a direction to be pressed against the inner surface of the hole opposite to the direction in which the engaging part is released while deforming the elastically deforming part. Thereby, the attachment state of the plug body with respect to the hole to be attached is stably maintained. That is, such a plug body can be configured to be easily inserted into a hole to be attached, while being configured to be difficult to be removed from the hole.

前記案内部及び被案内部の双方又は一方を、軸部の軸線に対して傾きを持った傾斜面としておくことが、この発明の好ましい態様の一つとなる。   It is one of the preferable aspects of the present invention that both or one of the guide portion and the guided portion is an inclined surface having an inclination with respect to the axis of the shaft portion.

以下、図1〜図11に基づいて、この発明の典型的な実施の形態について、説明する。この実施の形態にかかる樹脂製プラグ体は、取付対象Nに形成された孔Naに頭部1以外の部分を挿入可能で且つこの挿入によりこの孔Na側に掛合可能に構成されて、かかる掛合により前記取付対象Nに取り付け用いられるものである。かかるプラグ体は、典型的にはプラスチック材料を金型を使って成形することにより構成される。かかるプラグ体は、前記取付対象Nに取り付けられて、前記頭部1とこの取付対象Nとの間で別の対象物(図示は省略する。)を挟み込み状に保持するように用いることもできる。すなわち、かかるプラグ体は、いわゆるホールプラグとして用いることができるだけでなく、いわゆるクリップとしても用いることができるものである。   Hereinafter, typical embodiments of the present invention will be described with reference to FIGS. The resin plug body according to this embodiment is configured so that a portion other than the head 1 can be inserted into the hole Na formed in the attachment target N and can be engaged with the hole Na by this insertion. Is attached to the attachment object N. Such a plug body is typically formed by molding a plastic material using a mold. Such a plug body is attached to the attachment object N, and can also be used so as to hold another object (not shown) sandwiched between the head 1 and the attachment object N. . That is, such a plug body can be used not only as a so-called hole plug but also as a so-called clip.

かかるプラグ体は、頭部1と、軸部2と、掛合部3とを備えている。
図1〜図8に示される第一例及び図9に示される第二例では、一つの頭部1の一方側に一つの軸部2と掛合部3とを形成させてプラグ体を構成させている。
図10に示される第三例では、一つの頭部1の一方側に一つの軸部2を形成させると共に、この軸部2の両側にそれぞれ掛合部3を形成させてプラグ体を構成させている。
図11に示される第四例では、一つの頭部1の両側にそれぞれ、軸部2及び掛合部3を形成させてプラグ体を構成させている。
The plug body includes a head 1, a shaft portion 2, and a hook portion 3.
In the first example shown in FIGS. 1 to 8 and the second example shown in FIG. 9, a plug body is formed by forming one shaft portion 2 and a hook portion 3 on one side of one head 1. ing.
In the third example shown in FIG. 10, one shaft portion 2 is formed on one side of one head 1, and engaging portions 3 are formed on both sides of the shaft portion 2 to form a plug body. Yes.
In the fourth example shown in FIG. 11, the plug body is configured by forming the shaft portion 2 and the engaging portion 3 on both sides of one head 1.

頭部1は、前記取付対象Nの孔Naに入り込まない大きさを備えている。図示の例では、かかる頭部1は前記取付対象Nの孔Naに入り込まない大きさの円板状部10を有している。第一例〜第三例では、頭部1の他方側には、プラグ体を全体として捻り回し可能とする捻回操作用の操作部11が形成されている。図示の例では、かかる操作部11は、筒一端を頭部1の他方側の面に一体に連接させた短寸筒部11aを有している。この短寸筒部11aは、その筒軸に直交する断面において、その外側及び内側の輪郭形状をいずれも多角形、図示の例では六角形としている。これにより、前記孔Naに掛合した状態から、操作部11を手指で摘み持って、あるいは、工具を嵌め合わせることで、プラグ体をスムースに捻り回すことができるようになっている。図示の例では、掛合部3は、取付対象Nの孔Na内に形成された被掛合部Nbとしての雌ネジ部Ncに対応した雄ネジ部の一部よりなる掛合部分30を備え、この掛合部分30によって孔Na側に掛合されるようになっており、前記捻り回しによりプラグ体を螺退させて前記孔Naからプラグ体の前記頭部1以外の部分、つまり、前記軸部2と掛合部3を抜き出し前記取付対象Nからプラグ体を取り外せるようになっている。図示の例ではまた、前記短寸筒部11a内において頭部1にドライバの先端の嵌まる凹部11bが形成されている。これにより、図示の例では、短寸筒部11aに先端を外嵌めされるレンチ、短寸筒部11aに先端を内嵌めされるスパナ、前記凹部11bに対応した先端を持ったドライバのいずれによっても、プラグ体をスムースに捻り回すことができるようになっている。   The head 1 has a size that does not enter the hole Na of the attachment target N. In the illustrated example, the head 1 has a disk-shaped portion 10 having a size that does not enter the hole Na of the attachment target N. In the first to third examples, on the other side of the head 1, an operation portion 11 for twisting operation that allows the plug body to be twisted as a whole is formed. In the illustrated example, the operation unit 11 includes a short cylinder part 11 a in which one end of the cylinder is integrally connected to the other surface of the head 1. In the cross section perpendicular to the cylinder axis, the short cylindrical portion 11a has a polygonal outer shape and a hexagonal shape in the illustrated example. As a result, the plug body can be smoothly twisted by holding the operation unit 11 with fingers or fitting a tool from the state of being engaged with the hole Na. In the illustrated example, the hooking portion 3 includes a hooking portion 30 formed of a part of a male screw portion corresponding to the female screw portion Nc as the hooked portion Nb formed in the hole Na of the attachment target N. The portion 30 is engaged with the hole Na side, and the plug body is screwed out by the twisting to engage the portion other than the head portion 1 of the plug body from the hole Na, that is, the shaft portion 2. The part 3 is extracted and the plug body can be removed from the attachment object N. In the illustrated example, a concave portion 11b into which the tip of the driver fits is formed in the head portion 1 in the short cylindrical portion 11a. Thus, in the example shown in the drawing, any of a wrench having a tip fitted to the short cylindrical portion 11a, a spanner having a tip fitted to the short cylindrical portion 11a, and a driver having a tip corresponding to the concave portion 11b. However, the plug body can be twisted smoothly.

軸部2は、軸一端を前記頭部1の一方側に一体に連接させてこの頭部1から延出されている。図示の例では、軸部2の軸一端20は前記頭部1を構成する円板状部10の中央に一体に連接されている。   The shaft portion 2 extends from the head portion 1 with one end of the shaft integrally connected to one side of the head portion 1. In the illustrated example, the shaft end 20 of the shaft portion 2 is integrally connected to the center of the disk-shaped portion 10 constituting the head 1.

掛合部3は、前記軸部2の側方にあってこの軸部2の軸線xに交叉する向きの移動可能に弾性変形部4を介して前記頭部1又は軸部2に連接されている。第一例、第三例及び第四例では、前記軸部2と掛合部3とが弾性変形部4によって連接されている。一方、第二例では、前記頭部1と掛合部3とが弾性変形部4によって連接されている。図示の例では、掛合部3は、軸部2の軸一端20と軸他端21との間において、軸部2との間に間隔を開けて配されている。図示の例では、かかる掛合部3における軸部2に向き合う背面部33と反対の表面部32にネジ孔Naとして構成された前記取付対象Nの孔Naの内面の雌ネジ部Ncに対応した雄ネジ部の一部により構成された掛合部分30が形成されている。図示の例では、掛合部3の表面部32に、前記雄ネジ部のネジ山を構成するリブ31が、前記軸線方向において隣り合うリブ31との間に間隔を開けて三カ所設けられており、この三カ所のリブ31…31によって前記掛合部分30が構成されている。   The hook portion 3 is connected to the head portion 1 or the shaft portion 2 via the elastic deformation portion 4 so as to be movable in a direction crossing the axis line x of the shaft portion 2 on the side of the shaft portion 2. . In the first example, the third example, and the fourth example, the shaft portion 2 and the engaging portion 3 are connected by an elastic deformation portion 4. On the other hand, in the second example, the head 1 and the engaging portion 3 are connected by an elastic deformation portion 4. In the illustrated example, the engaging portion 3 is arranged between the shaft end 20 and the shaft other end 21 of the shaft portion 2 with a space from the shaft portion 2. In the illustrated example, the male portion Nc corresponding to the female screw portion Nc on the inner surface of the hole Na of the mounting target N formed as the screw hole Na on the surface portion 32 opposite to the back surface portion 33 facing the shaft portion 2 in the hook portion 3 is illustrated. An engaging portion 30 constituted by a part of the screw portion is formed. In the illustrated example, ribs 31 constituting the threads of the male screw portion are provided at three positions on the surface portion 32 of the engaging portion 3 with a gap between the ribs 31 adjacent in the axial direction. The hook portion 30 is constituted by the three ribs 31... 31.

そして、この実施の形態にかかるプラグ体にあっては、前記頭部1以外の部分を取付対象Nに形成された孔Naに挿入したときにこの孔Na内の被掛合部Nbに前記掛合部3を前記弾性変形部4の弾性力により掛合させるようになっている。図示の例では、軸部2における前記掛合部3の背面部33と向き合う側と反対の表面部26と、この掛合部3の表面部33との間の距離は、前記孔Naの雌ネジ部Ncのネジ山の頂部位置での内径よりもやや大きくなっている。従って、プラグ体の頭部1以外の部分の前記孔Naへの挿入は、掛合部3の掛合部分30と雌ネジ部Ncとの接触に伴うこの掛合部分30を軸部2に近接させる向きの前記弾性変形部4の弾性変形により許容される。(図6)前記孔Naへのプラグ体の頭部1以外の部分の挿入を止めると前記弾性変形部4の弾性復帰により前記雌ネジ部Ncに掛合部分30がかみ合いプラグ体の掛合部3の前記孔Na側への掛合がなされる。(図7)   And in the plug body concerning this embodiment, when a part other than the said head 1 is inserted in the hole Na formed in the attachment object N, the said engagement part is connected to the to-be-engaged part Nb in this hole Na. 3 is engaged by the elastic force of the elastic deformation portion 4. In the illustrated example, the distance between the surface portion 26 opposite to the side facing the back surface portion 33 of the hook portion 3 in the shaft portion 2 and the surface portion 33 of the hook portion 3 is the female screw portion of the hole Na. It is slightly larger than the inner diameter at the top position of the Nc thread. Accordingly, the insertion of the portion other than the head portion 1 of the plug body into the hole Na is performed in such a direction that the engagement portion 30 accompanying the contact between the engagement portion 30 of the engagement portion 3 and the female screw portion Nc is brought close to the shaft portion 2. Allowed by elastic deformation of the elastic deformation portion 4. (FIG. 6) When the insertion of the part other than the head 1 of the plug body into the hole Na is stopped, the engagement part 30 is engaged with the female thread part Nc by the elastic return of the elastic deformation part 4, and the engagement part 3 of the plug body Engagement with the hole Na side is performed. (Fig. 7)

また、この実施の形態にかかるプラグ体にあっては、前記軸部2に、前記頭部1以外の部分を前記孔Naから抜き出す向きの力が作用されたときに、前記掛合部3の被案内部34に接して前記孔Naの内面に押しつける向きにこの掛合部3を案内する案内部22が備えられている。   Further, in the plug body according to this embodiment, when a force is applied to the shaft portion 2 so as to extract a portion other than the head portion 1 from the hole Na, the covering portion 3 is covered. A guide portion 22 is provided that guides the engaging portion 3 in such a direction as to contact the guide portion 34 and press against the inner surface of the hole Na.

図示の例では、案内部22及び被案内部34の双方が、軸部2の軸線xに対して傾きを持った傾斜面t、t’となっている。案内部22は、軸部2における前記掛合部3の背面部33と向き合う側であって、この軸部2の軸線x方向略中程の位置に形成されている。図示の例では、案内部22の傾斜面tは軸部2の前記位置に形成された山状の膨出部23の頭部1側に向けられた側面よって形成されている。一方、掛合部3の傾斜面t’は、掛合部3の背面部33に形成されており、前記案内部22の傾斜面tと同じ向きの傾きを持ったものとなっている。すなわち、いずれの傾斜面t、t’も前記頭部1側に向かうに連れて軸部2の表面部26に近づく傾きを持つように構成されている。   In the illustrated example, both the guide portion 22 and the guided portion 34 are inclined surfaces t and t ′ that are inclined with respect to the axis x of the shaft portion 2. The guide portion 22 is formed on the shaft portion 2 on the side facing the back surface portion 33 of the hook portion 3 and at a position approximately in the middle of the shaft portion 2 in the axis x direction. In the illustrated example, the inclined surface t of the guide portion 22 is formed by a side surface directed to the head 1 side of the mountain-shaped bulged portion 23 formed at the position of the shaft portion 2. On the other hand, the inclined surface t ′ of the engaging portion 3 is formed on the back surface portion 33 of the engaging portion 3, and has an inclination in the same direction as the inclined surface t of the guide portion 22. That is, any of the inclined surfaces t and t ′ is configured to have an inclination that approaches the surface portion 26 of the shaft portion 2 as it goes toward the head 1 side.

取付対象Nの孔Naに頭部1以外の部分を挿入・掛合させた状態から、プラグ体にこの頭部1以外の部分を前記孔Naから抜き出す向きの力が作用されると、案内部22と被案内部34の協働によって、掛合部3は弾性変形部4を変形させながら被掛合部Nbとの掛合を解く向きと逆の前記孔Naの内面に押しつけられる向きに案内される。(図8)これにより取付対象Nの孔Naに対するプラグ体の取り付け状態は安定的に維持される。すなわち、かかるプラグ体は、取付対象Nの孔Naに挿入し易く構成できる一方で、この孔Naより抜け難く構成することができる。図示の例とは異なり、案内部22及び被案内部34のいずれか一方を、軸部2の軸線xに対して傾きを持った傾斜面としておいても同様の機能を奏することができる。   When a force is applied to the plug body in a direction in which a portion other than the head 1 is pulled out from the hole Na from a state in which a portion other than the head 1 is inserted and engaged with the hole Na of the attachment target N, the guide portion 22 is applied. By the cooperation of the guided portion 34, the engaging portion 3 is guided in a direction in which the engaging portion 3 is pressed against the inner surface of the hole Na opposite to the direction in which the engaging portion Nb is released while deforming the elastic deformation portion 4. (FIG. 8) Thereby, the attachment state of the plug body with respect to the hole Na of the attachment object N is stably maintained. That is, such a plug body can be configured to be easily inserted into the hole Na of the attachment target N, but can be configured to be difficult to come out from the hole Na. Unlike the example shown in the figure, the same function can be achieved even if one of the guide portion 22 and the guided portion 34 is an inclined surface inclined with respect to the axis x of the shaft portion 2.

(第一例)
図1〜図8に示される第一例では、軸部2の軸他端21は、頭部1の中心を通る仮想の直線y上に円の中心を位置させる円板体24によって構成されている。軸部2の軸他端21と軸一端20との間は、軸他端21より細く、前記仮想の直線yとの間に間隔を開けて形成された前記掛合部3側に向いた背面部25と、前記仮想の直線yを中心軸とする仮想の円柱の外面に倣った表面部26とから構成されている。この第一例では、弾性変形部4は、軸部2の軸他端21と膨出部23との間において前記背面部25から前記軸線xに略直交する向きに突き出すと共に、膨出部23の頂部より前方となる位置において頭部1側に向けて屈曲されてこの頭部1側に向けられた端部を掛合部3における軸他端21側に向けられた側部に一体に連接させた屈曲腕部40によって構成されている。
(First example)
In the first example shown in FIGS. 1 to 8, the shaft other end 21 of the shaft portion 2 is configured by a disc body 24 that positions the center of a circle on a virtual straight line y passing through the center of the head 1. Yes. A back surface portion between the shaft other end 21 and the shaft one end 20 of the shaft portion 2 is narrower than the shaft other end 21 and is formed with a space between the virtual straight line y and facing the engaging portion 3 side. 25 and a surface portion 26 that follows the outer surface of a virtual cylinder having the virtual straight line y as a central axis. In this first example, the elastic deformation portion 4 protrudes from the back surface portion 25 in a direction substantially perpendicular to the axis line x between the shaft other end 21 of the shaft portion 2 and the bulging portion 23, and the bulging portion 23. The end portion that is bent toward the head 1 side at a position in front of the top of the head and directed toward the head 1 side is integrally connected to the side portion of the hooking portion 3 that faces toward the other end 21 of the shaft. The bent arm portion 40 is configured.
