本発明は、ボルトに取り付けるボルトクリップに関する。   The present invention relates to a bolt clip attached to a bolt.

車両の車体などの板状部材にはスタッドボルトが板状部材から突出した状態で取り付けられる。所定の部品を車体に固定するため、そのスタッドボルトにはボルトクリップが装着される。   A stud bolt is attached to a plate-like member such as a vehicle body of the vehicle in a state of protruding from the plate-like member. In order to fix a predetermined part to the vehicle body, a bolt clip is attached to the stud bolt.

特許文献1は、自動車部品を車体パネルに固定するために用いるものであって、スタッドボルトに係止するプッシュナットを開示する。このプッシュナットは、中空胴部と、中空胴部の内側に形成された複数の係止爪とを有する。中空胴部にスタッドボルトが挿入されると、係止爪がスタッドボルトの螺旋溝に係止する。   Patent document 1 is used in order to fix an automobile part to a vehicle body panel, and discloses a push nut that is locked to a stud bolt. This push nut has a hollow body part and a plurality of locking claws formed inside the hollow body part. When the stud bolt is inserted into the hollow body, the locking claw is locked in the spiral groove of the stud bolt.

特開平9−273528号公報JP-A-9-273528

特許文献1に記載の技術は、プッシュナットに係止爪を一体に設ける構成であるため、作業者がプッシュナットをスタッドボルトに挿入して所定の荷重で押し込んで固定を完了する際に、どこまで挿入しているか把握することが難しい。押し込み力が弱いとスタッドボルトへの固定が不完全になり、プッシュナットに固定する部品にガタが生じるおそれがある一方、押し込み力が強すぎると固定する部品を傷つけたり、固定保持期間中に係止爪が破損するおそれがある。   Since the technology described in Patent Document 1 is a structure in which a locking claw is provided integrally with a push nut, when the operator inserts the push nut into the stud bolt and pushes it with a predetermined load to complete the fixing. It is difficult to grasp whether it is inserted. If the pushing force is weak, fixing to the stud bolt may be incomplete, and there is a risk of looseness in the parts that are fixed to the push nut. On the other hand, if the pushing force is too strong, the fixing parts may be damaged or the The pawl may be damaged.

本発明はこのような課題に鑑みてなされたものであり、その目的は、作業者に取り付け完了を示す操作感を伝達して押し込み力のバラツキを抑えるとともに、小型化を実現するボルトクリップを提供することにある。   The present invention has been made in view of such a problem, and an object of the present invention is to provide a bolt clip that transmits an operational feeling indicating the completion of attachment to an operator to suppress variation in pushing force and achieve miniaturization. There is to do.

上記課題を解決するために、本発明のある態様のボルトクリップは、ボルトに装着されて部品を固定するボルトクリップであって、ボルトが挿入される中央孔を有するベース部材と、ベース部材に取り付けられるキャップ部材と、を備える。ベース部材は、中央孔を取り囲むベース柱状部と、ベース柱状部の内側に形成され、ボルトのねじ溝に係合する複数の弾性爪体と、ベース柱状部の内側に形成され、ボルトに近接対向する突状部と、ベース柱状部の外側でキャップ部材を係止する係止部を有する複数の弾性部材と、を有し、弾性爪体と弾性部材とは周回り方向に交互に配置され、キャップ部材は、ベース柱状部の外周を覆う中空のキャップ柱状部と、キャップ柱状部に軸方向に並んで配置され、係止部を受け入れる2つの受入部と、を有する。ベース柱状部およびキャップ柱状部は、互いの相対回転を規制する形状を有する。このボルトクリップは、中央孔にボルトが挿入されてキャップ部材が押し込まれると弾性爪体が撓んでボルトのねじ溝からねじ山を乗り越え、さらに押し込まれると一方の受入部に位置していた係止部が他方の受入部に移動し、キャップ部材が押し込まれて弾性爪体がボルトのねじ溝からねじ山を乗り越えるために必要な第1荷重と、キャップ部材が押し込まれて係止部が一方の受入部から他方の受入部へ移動するために必要な第2荷重とを比べると、第2荷重が第1荷重より大きい。   In order to solve the above-described problem, a bolt clip according to an aspect of the present invention is a bolt clip that is attached to a bolt and fixes a component, and has a base member having a central hole into which the bolt is inserted, and is attached to the base member. A cap member. The base member is formed inside the base columnar part surrounding the central hole, a plurality of elastic claws formed inside the base columnar part and engaged with the screw groove of the bolt, and formed inside the base columnar part, in close proximity to the bolt. And a plurality of elastic members having locking portions for locking the cap member outside the base columnar portion, and the elastic claws and the elastic members are alternately arranged in the circumferential direction, The cap member includes a hollow cap columnar portion that covers the outer periphery of the base columnar portion, and two receiving portions that are arranged side by side in the axial direction on the cap columnar portion and receive the locking portion. The base columnar portion and the cap columnar portion have shapes that restrict relative rotation of each other. When this bolt clip is inserted into the center hole and the cap member is pushed in, the elastic claw body bends and climbs over the thread from the screw groove of the bolt, and when it is pushed further, it is located at one receiving part. Part moves to the other receiving part, the cap member is pushed in, the first load necessary for the elastic claw body to get over the screw thread from the screw groove of the bolt, and the cap member is pushed in and the locking part When compared with the second load required to move from the receiving part to the other receiving part, the second load is larger than the first load.

この態様によると、第2荷重が第1荷重より大きいため、先に弾性爪体が撓んでボルトを受け入れ、ベース部材がボルトを支持する台座に着座してからさらに押し込まれない限り、ベース部材の弾性部材の係止部がキャップ部材の他方の受入部に移動しない。これによりベース部材の弾性部材の係止部がキャップ部材の他方の受入部に移動したときにボルトへの取り付けが完了するため、作業者は係止部の移動を確認することで取り付けが完了したことを認識することができる。また、弾性爪体の弾性力を確保して、突状部によりボルトの位置ずれを抑え、さらに弾性部材の撓み幅を確保するためにはそれぞれ径方向の幅を確保する必要があるが、複数の弾性爪体と弾性部材を周回り方向に交互に配置することで、小型化を図ることができる。   According to this aspect, since the second load is larger than the first load, unless the elastic claw body first bends and receives the bolt, and the base member is seated on the pedestal that supports the bolt and then pushed further, The locking portion of the elastic member does not move to the other receiving portion of the cap member. As a result, when the locking portion of the elastic member of the base member moves to the other receiving portion of the cap member, the mounting to the bolt is completed, so the operator has completed the mounting by confirming the movement of the locking portion I can recognize that. Moreover, in order to secure the elastic force of the elastic claw body, to suppress the displacement of the bolt by the projecting portion, and to secure the bending width of the elastic member, it is necessary to secure the width in the radial direction. By alternately arranging the elastic claws and elastic members in the circumferential direction, the size can be reduced.

本発明によれば、作業者に取り付け完了を示す操作感を伝達しつつ、小型化を実現したボルトクリップを提供できる。   ADVANTAGE OF THE INVENTION According to this invention, the bolt clip which implement | achieved size reduction can be provided, conveying the operation feeling which shows completion of attachment to an operator.

図1は、実施形態に係るボルトクリップ10の斜視図である。図1(a)はボルトクリップ10をスタッドボルトに取り付ける前の状態を示し、図1(b)はボルトクリップ10のスタッドボルトへの取り付けが完了した状態を示す。ここで各図面に示される同一または同等の構成要素、部材には、同一の符号を付するものとし、適宜重複した説明は省略する。   FIG. 1 is a perspective view of a bolt clip 10 according to the embodiment. 1A shows a state before the bolt clip 10 is attached to the stud bolt, and FIG. 1B shows a state where the attachment of the bolt clip 10 to the stud bolt is completed. Here, the same or equivalent components and members shown in the drawings are denoted by the same reference numerals, and repeated description thereof is omitted as appropriate.

ボルトクリップ10は、たとえば車体パネルに取り付けられたスタッドボルトに挿入して所定の部品を固定する。たとえばスタッドボルトは車体パネルのうち車輪の後部の箇所から突出し、そのスタッドボルトに泥よけカバーの取り付け孔を嵌め合わせて泥よけカバーを装着し、さらにその上からスタッドボルトにボルトクリップ10の中央孔を合わせてボルトクリップ10を挿入して所定の押し込み力で押しつけることにより固定される。ボルトクリップ10の外形はたとえば6角柱状に形成されている。スタッドボルトの外周面にはねじ溝が形成されている。   The bolt clip 10 is inserted into a stud bolt attached to the vehicle body panel, for example, and fixes a predetermined part. For example, the stud bolt protrudes from the rear part of the wheel of the vehicle body panel, the mudguard cover mounting hole is fitted to the stud bolt, and the mudguard cover is attached to the stud bolt. The bolts 10 are inserted by aligning the center holes and fixed by pressing with a predetermined pushing force. The outer shape of the bolt clip 10 is formed in a hexagonal prism shape, for example. A thread groove is formed on the outer peripheral surface of the stud bolt.

ボルトクリップ10は、スタッドボルトが挿入される中央孔を有し、スタッドボルトに装着するベース部材20と、ベース部材20に取り付けるキャップ部材50とを備える。それぞれの部材について以下の図を用いて具体的に説明する。   The bolt clip 10 has a central hole into which the stud bolt is inserted, and includes a base member 20 that is attached to the stud bolt and a cap member 50 that is attached to the base member 20. Each member will be specifically described with reference to the following drawings.

図2は、実施形態に係るベース部材20の斜視図を示す。また図3は、実施形態に係るベース部材20を3方向から見た図を示す。図3(a)は上面図を示し、図3(b)は側面図を示し、図3(c)は下面図を示す。ベース部材20は、座部22、フランジ部24、ベース柱状部26、係止部28、弾性部材30、突状部32、直立部34、弾性爪体38およびガイド溝40を有する。   FIG. 2 is a perspective view of the base member 20 according to the embodiment. Moreover, FIG. 3 shows the figure which looked at the base member 20 which concerns on embodiment from 3 directions. FIG. 3A shows a top view, FIG. 3B shows a side view, and FIG. 3C shows a bottom view. The base member 20 includes a seat portion 22, a flange portion 24, a base columnar portion 26, a locking portion 28, an elastic member 30, a protruding portion 32, an upright portion 34, an elastic claw body 38, and a guide groove 40.

座部22は円盤形状に形成され、その中央にはベース中央孔44が形成される。座部22の外周に径方向に延在するフランジ部24が形成される。また座部22の上面にはベース柱状部26が立設する。フランジ部24は下方に垂れるように傘状に形成され、厚さが座部22より薄肉で形成されて弾性を有する。   The seat portion 22 is formed in a disk shape, and a base central hole 44 is formed at the center thereof. A flange portion 24 extending in the radial direction is formed on the outer periphery of the seat portion 22. A base columnar portion 26 stands on the upper surface of the seat portion 22. The flange portion 24 is formed in an umbrella shape so as to hang downward, and is thinner than the seat portion 22 and has elasticity.

ベース柱状部26の断面は、6角形状の3辺を凹ませた形状である。ベース柱状部26の最外径に位置する部分であって、6角の頂点に相当する箇所を直立部34という。隣り合う直立部34は壁部により連結される。壁部の一部には内向きに凹んだ内方突出壁部46が3箇所に設けられる。ベース柱状部26は中央孔を取り囲む。   The cross section of the base columnar portion 26 has a shape in which three sides of a hexagonal shape are recessed. A portion located at the outermost diameter of the base columnar portion 26 and corresponding to a hexagonal apex is referred to as an upright portion 34. Adjacent upright portions 34 are connected by a wall portion. Inwardly projecting wall portions 46 that are recessed inwardly are provided in three portions of the wall portions. The base columnar portion 26 surrounds the central hole.

内方突出壁部46には中心軸に向かって突出する突状部32が形成される。突状部32はベース柱状部26の内側に形成され、内方突出壁部46の内壁面から突出する。突状部32は、挿入されたスタッドボルトに近接対向し、突状部32はスタッドボルトの動きを規制してガタツキを抑える。なお突状部32は、突出した内方突出壁部46自体であってもよい。   The inward protruding wall portion 46 is formed with a protruding portion 32 that protrudes toward the central axis. The protruding portion 32 is formed inside the base columnar portion 26 and protrudes from the inner wall surface of the inward protruding wall portion 46. The projecting portion 32 is in close proximity to the inserted stud bolt, and the projecting portion 32 restricts the movement of the stud bolt and suppresses rattling. The protruding portion 32 may be the protruding inner protruding wall portion 46 itself.

内方に凹んだ内方突出壁部46により形成された空隙42に弾性部材30が設けられる。なお空隙42については後段にて詳述する。外壁面36の内方突出壁部46が設けられていない箇所には軸方向に伸びるガイド溝40が形成される。弾性部材30は、座部22から立設する本体部31と、本体部31から径方向外向きに突出する爪状の係止部28とを有する。係止部28はベース柱状部26の外側でキャップ部材50を係止する。   The elastic member 30 is provided in the space 42 formed by the inwardly projecting wall portion 46 that is recessed inwardly. The gap 42 will be described in detail later. A guide groove 40 extending in the axial direction is formed in a portion of the outer wall surface 36 where the inward protruding wall portion 46 is not provided. The elastic member 30 includes a main body portion 31 standing from the seat portion 22 and a claw-shaped locking portion 28 that protrudes radially outward from the main body portion 31. The locking portion 28 locks the cap member 50 outside the base columnar portion 26.

弾性爪体38は、ベース柱状部26の内側に3箇所で形成され、座部22から中心方向に傾斜して立設する。3つの弾性爪体38は周方向に等間隔に配置される。弾性爪体38の先端がスタッドボルトのねじ山に引っかかり、スタッドボルトに係合する。   The elastic claws 38 are formed at three locations on the inner side of the base columnar portion 26 and are erected from the seat portion 22 while being inclined toward the center. The three elastic claws 38 are arranged at equal intervals in the circumferential direction. The tip of the elastic claw 38 is caught by the thread of the stud bolt and engages with the stud bolt.

図3(a)に示すように弾性爪体38を傾斜させて径方向にも延在させることで所定の弾性力を得て、スタッドボルトにしっかり係合させることができる。弾性部材30が所定の弾性力を得るためには弾性爪体38の径方向幅を確保する必要がある。一方、弾性部材30は内向きに撓むため、弾性部材30より径方向内側に所定の空間を確保する必要がある。実施形態では複数の弾性爪体38と弾性部材30とは周回り方向に交互に配置される。このように、交互に配置することで、弾性爪体38の弾性力および弾性部材30に必要な径方向の空間を確保しつつ、ベース部材20の直径を小さくでき、コストを抑えることができる。なお突状部32は弾性部材30の径方向内側に配置されているため、突状部32と弾性爪体38が周回り方向に交互に配置されている。   As shown in FIG. 3A, a predetermined elastic force can be obtained by inclining the elastic claw 38 and extending in the radial direction, and can be firmly engaged with the stud bolt. In order for the elastic member 30 to obtain a predetermined elastic force, it is necessary to ensure the radial width of the elastic claw body 38. On the other hand, since the elastic member 30 bends inward, it is necessary to secure a predetermined space radially inward from the elastic member 30. In the embodiment, the plurality of elastic claws 38 and the elastic members 30 are alternately arranged in the circumferential direction. Thus, by arranging alternately, the diameter of the base member 20 can be made small, and cost can be suppressed, ensuring the elastic force of the elastic claw body 38 and the radial space required for the elastic member 30. Since the protrusions 32 are arranged on the radially inner side of the elastic member 30, the protrusions 32 and the elastic claws 38 are alternately arranged in the circumferential direction.

図4は、実施形態に係るキャップ部材50の裏側を見た斜視図を示す。また図5は、実施形態に係るキャップ部材50を3方向から見た図を示す。図5(a)は上面図を示し、図5(b)は側面図を示し、図5(c)は下面図を示す。   FIG. 4 is a perspective view of the back side of the cap member 50 according to the embodiment. Moreover, FIG. 5 shows the figure which looked at the cap member 50 which concerns on embodiment from 3 directions. 5A shows a top view, FIG. 5B shows a side view, and FIG. 5C shows a bottom view.

キャップ部材50は、キャップ柱状部52、上蓋部54、張出部58、第1受入部60および第2受入部62を有する。中空のキャップ柱状部52は、ベース柱状部26の外周を覆う。キャップ柱状部52の上端には上蓋部54が設けられ、上蓋部54の中央にはキャップ中央孔56が形成される。図4および図5(c)に示すようにキャップ柱状部52の内壁面は、ベース柱状部26の形状に応じて6角柱状に形成される。したがって、ベース柱状部26およびキャップ柱状部52は、互いの相対回転を規制する形状である。   The cap member 50 includes a cap columnar part 52, an upper lid part 54, an overhang part 58, a first receiving part 60, and a second receiving part 62. The hollow cap columnar part 52 covers the outer periphery of the base columnar part 26. An upper lid portion 54 is provided at the upper end of the cap columnar portion 52, and a cap center hole 56 is formed at the center of the upper lid portion 54. As shown in FIGS. 4 and 5C, the inner wall surface of the cap columnar portion 52 is formed in a hexagonal column shape according to the shape of the base columnar portion 26. Therefore, the base columnar portion 26 and the cap columnar portion 52 have a shape that restricts relative rotation of each other.

第1受入部60および第2受入部62は、キャップ柱状部52に軸方向に並んで配置され、弾性部材30の数に応じて3つずつ形成される。第1受入部60および第2受入部62はキャップ柱状部52に形成された孔であり、この孔に係止部28を受け入れる。なお、第1受入部60および第2受入部62を区別しない場合は単に受入部という。   The first receiving part 60 and the second receiving part 62 are arranged side by side in the axial direction on the cap columnar part 52, and three are formed according to the number of elastic members 30. The first receiving part 60 and the second receiving part 62 are holes formed in the cap columnar part 52, and the locking part 28 is received in these holes. In addition, when not distinguishing the 1st receiving part 60 and the 2nd receiving part 62, it is only called a receiving part.

キャップ柱状部52の内壁面には中心方向に張り出し、軸方向に伸びる張出部58が形成される。張出部58はベース部材20のガイド溝40に摺動可能に嵌まる。なお、キャップ柱状部52にガイド溝が形成され、ベース柱状部26に張出部が形成されてよい。すなわち、キャップ柱状部52の内壁面およびベース柱状部26の外壁面の一方に軸方向に伸びる張出部が形成され、他方に軸方向に伸びるガイド溝部が形成される。これにより、ベース部材20とキャップ部材50の相対回転を防止して、弾性部材30と受入部の位置を確実に合わせることができる。張出部58と受入部とは、ともにキャップ柱状部52の内壁面に形成され、周方向に交互に配設される。   On the inner wall surface of the cap columnar portion 52, a protruding portion 58 is formed that extends in the center direction and extends in the axial direction. The overhang portion 58 is slidably fitted into the guide groove 40 of the base member 20. Note that a guide groove may be formed in the cap columnar portion 52, and an overhang portion may be formed in the base columnar portion 26. That is, an overhanging portion extending in the axial direction is formed on one of the inner wall surface of the cap columnar portion 52 and the outer wall surface of the base columnar portion 26, and a guide groove portion extending in the axial direction is formed on the other side. Thereby, the relative rotation of the base member 20 and the cap member 50 can be prevented, and the positions of the elastic member 30 and the receiving portion can be reliably matched. Both the protruding portion 58 and the receiving portion are formed on the inner wall surface of the cap columnar portion 52 and are alternately arranged in the circumferential direction.

ここで図2および図4を参照する。弾性爪体38は、ベース柱状部26の下端側から上端側に向かうほど中央孔の内側へ向かうように傾斜している。一方、係止部28を有する弾性部材30とスタッドボルトに近接対向する突状部32とは、空隙42を介して突状部32を空隙42の径方向内側に、弾性部材30を空隙42の径方向外側に位置させる。これにより、弾性爪体38に関して傾斜させることで十分に長いアーム長さを確保でき、太さにより強度、長さにより柔軟さを、両立してボルトクリップ10の最重要特性を確保できる。このように最優先して設置した弾性爪体38の周方向の隣には、突状部32、空隙42、および弾性部材30を位置させたことにより、突状部32は弾性撓みを必要とせずスタッドボルトに近接してガタツキを防止でき、前記弾性部材は空隙42により撓み可能となる。これらの結果、十分な強度等の特性を確保しつつ小型化が可能である。   Reference is now made to FIGS. The elastic claw body 38 is inclined so as to go to the inside of the central hole as it goes from the lower end side to the upper end side of the base columnar portion 26. On the other hand, the elastic member 30 having the locking portion 28 and the protruding portion 32 that is close to and opposed to the stud bolt have the protruding portion 32 in the radial direction inside the gap 42 through the gap 42 and the elastic member 30 in the gap 42. It is located radially outside. Accordingly, a sufficiently long arm length can be ensured by inclining the elastic claw body 38, and the most important characteristics of the bolt clip 10 can be ensured while attaining both strength and flexibility by the thickness. The protrusion 32, the gap 42, and the elastic member 30 are positioned next to the circumferential direction of the elastic claw 38 placed with the highest priority in this manner, so that the protrusion 32 needs to be elastically bent. Therefore, rattling can be prevented in the vicinity of the stud bolt, and the elastic member can be bent by the gap 42. As a result, it is possible to reduce the size while securing characteristics such as sufficient strength.

ベース柱状部26の外形に応じてキャップ柱状部52の内壁面のラジアル方向断面が6角形状に形成される。ベース柱状部26の外壁面36のラジアル方向断面は、キャップ柱状部52の内壁面のラジアル方向断面の6角形状に対応する6角の頂点を有し、かつ、その6角の頂点の隣り合う2点を結ぶ辺の少なくとも一つに中心方向に向かって凹む内方突出部を有する。6角形の張り出した辺の内側に弾性爪体38を位置させてその長さを十分に確保でき、中心に向かって凹んだ内方突出部に突状部32を、その外側空間に弾性部材50を位置させて、より一層小型化できる。なお、この内方突出部は内方突出壁部46を形成する一部をいう。キャップ部材50はベース柱状部26にキャップ柱状部52を嵌めるように組み付けられる。ベース柱状部26の外壁面36は、キャップ柱状部52の内壁面に接触する面37と接触しない面(内方突出壁部46の外面)がある。ベース柱状部26は、内方突出壁部46によりキャップ柱状部52の内壁面に接触しないように中心方向に向かって凹んだ空隙42を形成し、空隙42に弾性部材30が配される。内方突出壁部46と弾性部材30の間も所定幅の空間が形成されており、その空間が弾性部材30が径方向内向きに撓むスペースとなる。弾性部材30の本体部31はキャップ柱状部52の内壁面に接触する。   The radial cross section of the inner wall surface of the cap columnar portion 52 is formed in a hexagonal shape according to the outer shape of the base columnar portion 26. The radial cross section of the outer wall surface 36 of the base columnar portion 26 has a hexagonal apex corresponding to the hexagonal shape of the radial cross section of the inner wall surface of the cap columnar portion 52 and is adjacent to the hexagonal apex. At least one of the sides connecting the two points has an inward protruding portion that is recessed toward the center. The elastic claw body 38 is positioned inside the hexagonal protruding side to sufficiently secure the length thereof, the projecting portion 32 is formed in the inward projecting portion recessed toward the center, and the elastic member 50 is disposed in the outer space. Can be further reduced in size. In addition, this inward protrusion part means the part which forms the inward protrusion wall part 46. FIG. The cap member 50 is assembled so that the cap columnar portion 52 is fitted into the base columnar portion 26. The outer wall surface 36 of the base columnar portion 26 has a surface that does not contact the surface 37 that contacts the inner wall surface of the cap columnar portion 52 (the outer surface of the inwardly projecting wall portion 46). The base columnar portion 26 forms a void 42 that is recessed toward the center so as not to contact the inner wall surface of the cap columnar portion 52 by the inward protruding wall portion 46, and the elastic member 30 is disposed in the void 42. A space having a predetermined width is also formed between the inward projecting wall portion 46 and the elastic member 30, and this space becomes a space where the elastic member 30 bends inward in the radial direction. The main body portion 31 of the elastic member 30 contacts the inner wall surface of the cap columnar portion 52.

図6(a)〜図6(d)は、実施形態に係るボルトクリップ10の使用態様を説明する図である。なお、簡略のために固定される部品、たとえば泥よけカバーを省略している。図6ではボルトクリップ10の中心を通る断面図を示す。図6(a)は、図1(a)に示すスタッドボルト12への取り付け前の状態を示しており、作業者が手を触れて挿入作業を行うキャップ部材50と、スタッドボルト12の雄ねじの谷に係止する弾性爪体38を設けたベース部材20の2部品が予め組み付けされた状態であり、ボルトクリップ10はこの状態で提供される。第1受入部60は係止部28を受け入れた状態である。係止部28は第1受入部60の下面に引っかかり、ベース部材20とキャップ部材50が分離しないようにしている。なおベース中央孔44とキャップ中央孔56を区別しない場合は単に中央孔という。   Fig.6 (a)-FIG.6 (d) are the figures explaining the usage condition of the bolt clip 10 which concerns on embodiment. For simplicity, parts to be fixed, such as a mudguard cover, are omitted. FIG. 6 shows a cross-sectional view through the center of the bolt clip 10. FIG. 6A shows a state before attachment to the stud bolt 12 shown in FIG. 1A, and the cap member 50 on which the operator touches and inserts, and the male screw of the stud bolt 12 is shown. The two parts of the base member 20 provided with the elastic claw bodies 38 to be engaged with the valleys are assembled in advance, and the bolt clip 10 is provided in this state. The first receiving part 60 is in a state where the locking part 28 is received. The locking portion 28 is caught on the lower surface of the first receiving portion 60 so that the base member 20 and the cap member 50 are not separated. In addition, when not distinguishing the base center hole 44 and the cap center hole 56, they are simply called a center hole.

次に、図6(b)ではスタッドボルト12が中央孔に挿入し、取り付け途中の状態を示す。スタッドボルト12は車体パネル14に固定され、車体パネル14から突き出ている。作業者はキャップ部材50を掴んで、キャップ部材50を押してボルトクリップ10の中央孔にスタッドボルト12を挿入させる。弾性爪体38の先端はスタッドボルト12のねじ部分に当接しており、弾性によりねじ溝からねじ山を何度も越えながら挿入される。突状部32はスタッドボルト12に近接対向し、スタッドボルト12が中心軸からずれないようにしている。   Next, in FIG.6 (b), the stud bolt 12 is inserted in a center hole, and the state in the middle of attachment is shown. The stud bolt 12 is fixed to the vehicle body panel 14 and protrudes from the vehicle body panel 14. The operator grasps the cap member 50 and pushes the cap member 50 to insert the stud bolt 12 into the central hole of the bolt clip 10. The tip of the elastic claw body 38 is in contact with the threaded portion of the stud bolt 12, and is inserted while repeatedly exceeding the thread from the thread groove due to elasticity. The projecting portion 32 is in close proximity to the stud bolt 12 so that the stud bolt 12 does not deviate from the central axis.

図6(b)の状態において係止部28は、第1受入部60に受け入れられた状態である。弾性爪体38は、弾性部材30より弾性的に柔らかく形成され、弾性爪体38はスタッドボルト12から荷重を受けてねじ溝からねじ山を越えるように撓む。一方、ベース部材20は係止部28より弾性的に堅いため、ボルトクリップ10を押し込む際にキャップ部材50から荷重を受けてもほとんど撓まないように構成されている。そのため、挿入途中においては、弾性爪体38は撓んでスタッドボルト12のねじ山を越えるものの、弾性部材30は第1受入部60に受け入れられた状態を維持する。つまり、キャップ部材50が押し込まれて弾性爪体38がボルトのねじ溝からねじ山を乗り越えるために最低限必要な第1荷重と、キャップ部材50が押し込まれて係止部28が第1受入部60から第2受入部62へ移動するために最低限必要な第2荷重とを比べると、第2荷重が第1荷重より大きい。   In the state of FIG. 6B, the locking portion 28 is in a state received by the first receiving portion 60. The elastic claw body 38 is formed to be elastically softer than the elastic member 30, and the elastic claw body 38 receives a load from the stud bolt 12 and bends so as to exceed the thread from the thread groove. On the other hand, since the base member 20 is elastically stiffer than the locking portion 28, the base member 20 is configured to hardly bend even when a load is applied from the cap member 50 when the bolt clip 10 is pushed. Therefore, in the middle of insertion, the elastic claw body 38 bends and exceeds the thread of the stud bolt 12, but the elastic member 30 remains in a state of being received by the first receiving portion 60. That is, the cap member 50 is pushed in so that the elastic claw 38 can get over the thread from the screw groove of the bolt, and the minimum load necessary for the cap member 50 to be pushed in and the locking portion 28 is the first receiving portion. When compared with the second load that is the minimum required to move from 60 to the second receiving portion 62, the second load is larger than the first load.

次に、図6(c)ではフランジ部24が車体パネル14に接触した状態を示す。作業者がキャップ部材50を押してフランジ部24が車体パネル14に接触すると、フランジ部24は車体パネル14から反力を受ける。この反力が所定の荷重を越えると、弾性部材30が内向きに大きく撓んで、係止部28が第1受入部60から外れる。   Next, FIG. 6C shows a state in which the flange portion 24 is in contact with the vehicle body panel 14. When the operator presses the cap member 50 and the flange portion 24 comes into contact with the vehicle body panel 14, the flange portion 24 receives a reaction force from the vehicle body panel 14. When the reaction force exceeds a predetermined load, the elastic member 30 is greatly bent inward, and the locking portion 28 is detached from the first receiving portion 60.

次に、図6(d)ではボルトクリップ10のスタッドボルト12への取り付けが完了した状態を示し、図1(b)に示す状態でもある。図6(c)に示す状態からさらに押されて、係止部28が第2受入部62に受け入れられる。このように、中央孔にスタッドボルト12が挿入されて、ベース部材20がスタッドボルト12を支持する台座に着座してからさらに押し込まれると、一方の受入部に位置していた係止部28が他方の受入部に移動して、キャップ部材50が2つの受入部の間の距離分だけ滑動し、その後に第2受入部62が係止部28に受け入れられて滑動が終了することとなり、作業者の手には一瞬押し込み力無しに滑動した後に再度押し込み力が急増するという感覚が作業者に伝達され、作業者が係止部28の移動を確認し、取り付けを完了したことを認識することができる。これにより作業者はボルトクリップ10を確実に取り付けることができ、取り付け不良によってガタツキが発生する可能性を低減できる。   Next, FIG. 6D shows a state in which the bolt clip 10 is completely attached to the stud bolt 12, and is also a state shown in FIG. 1B. The locking portion 28 is received by the second receiving portion 62 by being further pushed from the state shown in FIG. As described above, when the stud bolt 12 is inserted into the central hole and the base member 20 is further pushed after being seated on the pedestal that supports the stud bolt 12, the locking portion 28 located at one receiving portion is The cap member 50 moves to the other receiving portion and slides by the distance between the two receiving portions, and then the second receiving portion 62 is received by the locking portion 28 and the sliding is finished. The operator feels that the pushing force suddenly increases again after sliding for a moment without any pushing force, and the worker confirms the movement of the locking portion 28 and recognizes that the installation is completed. Can do. As a result, the operator can securely attach the bolt clip 10 and reduce the possibility of rattling due to poor attachment.

次にボルトクリップ10の変形例を示す。図7は、ベース部材120の斜視図を示す。ボルトクリップ10では弾性爪体38が3つである態様を示したが、この変形例では弾性爪体138が2つである。またボルトクリップ10ではベース柱状部26の外形が6角を有する態様を示したが、この変形例ではベース柱状部126が円柱形状に形成される。   Next, a modified example of the bolt clip 10 will be shown. FIG. 7 shows a perspective view of the base member 120. Although the bolt clip 10 has an aspect in which there are three elastic claws 38, in this modification, there are two elastic claws 138. In the bolt clip 10, the base columnar portion 26 has a hexagonal outer shape. In this modification, the base columnar portion 126 is formed in a cylindrical shape.

ベース柱状部126は座部22から立設し、円柱形状の外形の一部が凹んで形成される。この凹んだ空間142は、対向して2つの内壁部146により形成され、それぞれに弾性部材130が配される。内壁部146の内側には中心に向かって突出する突状部132が形成される。突状部132はスタッドボルトに近接対向する。   The base columnar portion 126 is erected from the seat portion 22 and is formed with a part of the cylindrical outer shape being recessed. The recessed space 142 is formed by two inner wall portions 146 facing each other, and the elastic member 130 is disposed on each of them. A protruding portion 132 that protrudes toward the center is formed inside the inner wall portion 146. The projecting portion 132 is in close proximity to the stud bolt.

弾性爪体138は、座部22から内向きに傾斜して立設する。2つの弾性爪体138は対向して配置される。ベース柱状部26の外壁面には軸方向に伸びるガイド溝140が形成される。   The elastic claw body 138 is erected and inclined inward from the seat portion 22. The two elastic claws 138 are arranged to face each other. A guide groove 140 extending in the axial direction is formed on the outer wall surface of the base columnar portion 26.

また図8は、ベース部材120に取り付けるキャップ部材150の斜視図を示す。キャップ柱状部152の外形はキャップ柱状部52と同様に6角形状であるものの、内壁面は、ベース柱状部126に応じて円柱形状である。第1受入部60および第2受入部62は弾性部材130の位置に応じてキャップ柱状部152の内壁面にそれぞれ2つずつ形成される。また、張出部158もガイド溝140の位置に応じてキャップ柱状部152の内壁面に2つ形成される。この変形例においても、ボルトクリップ10と同様の効果が得られる。   FIG. 8 is a perspective view of the cap member 150 attached to the base member 120. Although the outer shape of the cap columnar portion 152 is hexagonal like the cap columnar portion 52, the inner wall surface has a columnar shape according to the base columnar portion 126. Two first receiving portions 60 and two second receiving portions 62 are respectively formed on the inner wall surface of the cap columnar portion 152 according to the position of the elastic member 130. Also, two overhanging portions 158 are formed on the inner wall surface of the cap columnar portion 152 according to the position of the guide groove 140. Also in this modified example, the same effect as the bolt clip 10 can be obtained.

本発明は上述の各実施例に限定されるものではなく、当業者の知識に基づいて各種の設計変更等の変形を各実施例に対して加えることも可能であり、そのような変形が加えられた実施例も本発明の範囲に含まれうる。   The present invention is not limited to the above-described embodiments, and various modifications such as design changes can be added to the embodiments based on the knowledge of those skilled in the art. Embodiments described may also be included within the scope of the present invention.

たとえば実施形態ではキャップ柱状部52に孔状の第1受入部60および第2受入部62を形成する態様を示したが、第1受入部60および第2受入部62は孔ではなく窪みであってよい。具体的にはキャップ柱状部52の内壁面に軸方向に並んで2つの窪みが形成され、その窪みに係止部28が受け入れられる。   For example, in the embodiment, a mode in which the hole-shaped first receiving portion 60 and the second receiving portion 62 are formed in the cap columnar portion 52 is shown. However, the first receiving portion 60 and the second receiving portion 62 are not holes but hollows. It's okay. Specifically, two recesses are formed in the inner wall surface of the cap columnar portion 52 in the axial direction, and the locking portion 28 is received in the recess.

また実施形態ではキャップ部材50がキャップ中央孔56を有する態様を示したが、キャップ中央孔56が形成されておらず、上蓋部54が閉じられた状態であってよい。スタッドボルト12をボルトクリップ10により完全に覆うことができる。   Moreover, although the cap member 50 showed the aspect which has the cap center hole 56 in embodiment, the cap center hole 56 may not be formed but the state which the upper cover part 54 was closed may be sufficient. The stud bolt 12 can be completely covered by the bolt clip 10.
