Description

本発明は、トリムボード等の部品と車体パネル等の部品とを連結するための、クリップに関する。   The present invention relates to a clip for connecting a component such as a trim board and a component such as a vehicle body panel.

例えば、トリムボード等の部品を、自動車の車体パネルや車体フレーム等の部品に連結する場合には、頭部及び脚部を有するクリップが用いられている。具体的には一方の部品に取付座を設けておき、この取付座にクリップの頭部を組付けておき、このクリップの脚部を他方の部品に設けた係止孔に挿入し係止させることで、クリップを介して一方の部品と他方の部品とが連結されるようになっている。   For example, when a part such as a trim board is connected to a part such as a vehicle body panel or a body frame of an automobile, a clip having a head and a leg is used. Specifically, a mounting seat is provided on one component, the head of the clip is assembled on the mounting seat, and the leg portion of this clip is inserted into the locking hole provided on the other component and locked. Thus, one part and the other part are connected via the clip.

従来のこの種のクリップとして、下記特許文献1には、頭部と係止脚とを有し、係止脚は、頭部の下面中央部から垂設した軸心部と、該軸心部から外方に放射状に突出した4つの突片と、これらの4つの突片の間に配置された4つの弾性係止片とから構成された止め具が記載されている。   As a conventional clip of this type, the following Patent Document 1 has a head and a locking leg, and the locking leg includes an axial center portion suspended from the center of the lower surface of the head, and the axial center portion. A stopper composed of four projecting pieces radially projecting outward from the four and four elastic locking pieces arranged between the four projecting pieces is described.

前記頭部は、大径な円形の鍔と、該鍔の上面中央部から立設した円柱状の頸部と、該頸部の上端に連結された小径な円形の鍔とから構成されている。また、トリムボードには、鍵穴形状をなした係止穴を有する取付座が設けられている。   The head is composed of a large-diameter circular heel, a columnar neck standing from the center of the upper surface of the heel, and a small-diameter circular heel connected to the upper end of the neck. . Further, the trim board is provided with a mounting seat having a locking hole having a keyhole shape.

そして、取付座に上記止め具を取付ける際には、まず、鍵穴形状をなした係止穴に、頭部の頸部を整合させて、その状態で止め具を押し込んでいく。すると、頭部の頸部が、係止穴の幅狭の導入通路を通ってその奥方の取付孔に嵌合し、係止穴の上下周縁に上方の鍔及び下方の鍔が係合して、両鍔により取付座が挟み込まれることにより、トリムボードに止め具が取付けられるようになっている。   When the stopper is attached to the mounting seat, first, the neck of the head is aligned with the locking hole having the keyhole shape, and the stopper is pushed in that state. Then, the neck of the head passes through the narrow introduction passage of the locking hole and fits into the mounting hole at the back, and the upper and lower rims engage with the upper and lower peripheral edges of the locking hole. The stopper is attached to the trim board by the attachment seat being sandwiched between the both sides.

なお、係止脚40の構造は特に限定はなく、例えば、頭部裏面から柱状部のステム部を設けておき、このステム部の先端から碇足状に一対の係止脚を設けたものなど、係止脚が他方の部品の係止孔に係止する構造であればよく、公知の構造を採用することができる。   The structure of the locking leg 40 is not particularly limited. For example, a column-shaped stem portion is provided from the back of the head, and a pair of locking legs are provided in a foot-like shape from the tip of the stem portion. Any structure may be used as long as the locking leg is locked to the locking hole of the other part, and a known structure can be adopted.

次に上記構成からなるクリップ10の使用方法について説明する。   Next, a method of using the clip 10 having the above configuration will be described.

まず、一方の部品1の取付座3にクリップ10の頭部20を装着する。すなわち、図1に示すように、クリップ10の第1フランジ部21を取付座3の底壁5の内面側に配置し、第2フランジ部23を底壁5の外面側に配置し、首部25を導入通路7のテーパ状通路7bに位置するように、取付座3の正面側開口にクリップ10の頭部20を整合させ、この状態で取付座3に向けてクリップ10を押し込んでいく。すると、クリップ10の首部25がテーパ状通路7bにガイドされながら導入通路7内を移動し、首部25が直線状通路7aに至ると、図6に示すように、首部25外周から突設された拡径部31が、直線状通路7aの内面に当接しながら移動する。そして、首部25が直線状通路7aを通過して取付孔6まで移動すると、幅狭の直線状通路7aにより首部25の戻りが阻止されると共に、第1フランジ部21が取付孔6の内面側周縁に係合し、第2フランジ部23の内側傾斜部23aの頂部23bが取付孔6の外面側周縁に係合して、両フランジ部21,23により取付座3の底壁5が挟み込まれて、頭部20が抜け止め保持されて、頭部20を介してクリップ10を取付座3に装着することができる(図7参照)。   First, the head 20 of the clip 10 is mounted on the mounting seat 3 of one component 1. That is, as shown in FIG. 1, the first flange portion 21 of the clip 10 is disposed on the inner surface side of the bottom wall 5 of the mounting seat 3, the second flange portion 23 is disposed on the outer surface side of the bottom wall 5, and the neck portion 25. The head 20 of the clip 10 is aligned with the opening on the front side of the mounting seat 3 so as to be positioned in the tapered passage 7b of the introduction passage 7, and the clip 10 is pushed toward the mounting seat 3 in this state. Then, the neck portion 25 of the clip 10 is moved in the introduction passage 7 while being guided by the tapered passage 7b. When the neck portion 25 reaches the linear passage 7a, as shown in FIG. The enlarged diameter portion 31 moves while contacting the inner surface of the linear passage 7a. When the neck portion 25 passes through the linear passage 7 a and moves to the attachment hole 6, the neck portion 25 is prevented from returning by the narrow linear passage 7 a and the first flange portion 21 is located on the inner surface side of the attachment hole 6. The top wall 23b of the inner inclined portion 23a of the second flange portion 23 is engaged with the outer surface side peripheral edge of the mounting hole 6 so that the bottom wall 5 of the mounting seat 3 is sandwiched between the flange portions 21 and 23. Thus, the head 20 is retained and the clip 10 can be attached to the mounting seat 3 via the head 20 (see FIG. 7).

そして、このクリップ10においては、導入通路7に首部25を挿入して押し込んでいくときに、図6に示すように、首部25の軸方向両端部に設けられた第1環状凹部33,第2環状凹部37に、導入通路7の直線状通路7aにおける上下周縁の角部や、同角部に生じたバリ等を入り込ませて、これらの角部やバリ等が首部25に接触することを抑制して、首部25の軸方向中間部に突設された拡径部31のみを、直線状通路7aの内面に当接させることができるので、首部外周と導入通路内面との接触面積を小さくして、導入通路7への首部25の挿入抵抗を低く抑えることができ、頭部20を取付座3にスムーズに装着することができる。   In the clip 10, when the neck 25 is inserted and pushed into the introduction passage 7, as shown in FIG. 6, the first annular recess 33 and the second annular recess 33 provided at both ends in the axial direction of the neck 25. The corners of the upper and lower peripheral edges of the linear passage 7a of the introduction passage 7 and the burrs generated at the same corners are inserted into the annular recess 37 to prevent these corners and burrs from coming into contact with the neck 25. Since only the diameter-expanded portion 31 protruding from the axially intermediate portion of the neck portion 25 can be brought into contact with the inner surface of the linear passage 7a, the contact area between the outer periphery of the neck portion and the inner surface of the introduction passage can be reduced. Thus, the insertion resistance of the neck 25 into the introduction passage 7 can be kept low, and the head 20 can be smoothly mounted on the mounting seat 3.

また、この実施形態における拡径部31は、首部25の軸方向両端部と、第1フランジ部21及び第2フランジ部23との連結部外周に形成された各R状部35の、第1フランジ部21又は第2フランジ部23との連結端部35aよりも、外径方向に突出しているので(図6参照)、取付座3に頭部20を装着すべく導入通路7に首部25を挿入するときに、各R状部35が、導入通路7の直線状通路7a周縁の角部に接触するのを防止して、挿通抵抗をより確実に低減することができる。   Moreover, the enlarged diameter part 31 in this embodiment is the 1st of each R-shaped part 35 formed in the axial direction both ends of the neck part 25, and the connection part outer periphery of the 1st flange part 21 and the 2nd flange part 23. Since it protrudes in the outer diameter direction from the connecting end portion 35a with the flange portion 21 or the second flange portion 23 (see FIG. 6), the neck portion 25 is provided in the introduction passage 7 so as to attach the head portion 20 to the mounting seat 3. When inserting, each R-shaped part 35 can be prevented from coming into contact with the corner of the peripheral edge of the straight passage 7a of the introduction passage 7, and the insertion resistance can be more reliably reduced.

更に本実施形態では、拡径部31の断面形状が円弧状曲面をなし、その頂部が導入通路7の直線状通路7aの内面と線接触するようになっているので(図6参照)、拡径部31と導入通路内面との接触面積をより小さくすることができ、導入通路7に対する首部25の挿入抵抗を更に低くすることができる。   Furthermore, in this embodiment, the cross-sectional shape of the enlarged diameter portion 31 is an arcuate curved surface, and the top portion is in line contact with the inner surface of the linear passage 7a of the introduction passage 7 (see FIG. 6). The contact area between the diameter portion 31 and the inner surface of the introduction passage can be further reduced, and the insertion resistance of the neck portion 25 with respect to the introduction passage 7 can be further reduced.

また、この実施形態における拡径部31は、拡径部31が首部25の外周に沿って環状に突出しているので、取付座3に頭部20を装着すべく導入通路7に首部25を挿入するときに、首部25をどのような方向から挿入しても、拡径部31を導入通路の7の直線状通路7aの内面に確実に当接させることができ、取付座3に対する頭部20の装着作業性を向上させることができる。   Moreover, since the enlarged diameter part 31 protrudes cyclically | annularly along the outer periphery of the neck part 25, the enlarged diameter part 31 in this embodiment inserts the neck part 25 in the introduction channel | path 7 so that the head 20 may be mounted | worn. When the neck portion 25 is inserted from any direction, the enlarged diameter portion 31 can be reliably brought into contact with the inner surface of the linear passage 7a of the introduction passage 7, and the head portion 20 with respect to the mounting seat 3 The mounting workability can be improved.

更に本実施形態では、第2フランジ部23側に設けられた第2環状凹部37は、首部25の径方向に凹むと共に、第2フランジ部23に向けて軸方向にも凹んだ形状をなしているので、導入通路7の直線状通路7a周縁の角部から、軸方向に直交する方向や、斜め方向、更には軸方向の、どのような方向にバリが突出していても、これらを第2環状凹部37に受け入れて、首部25に接触することを確実に防止することができる。   Further, in the present embodiment, the second annular concave portion 37 provided on the second flange portion 23 side is recessed in the radial direction of the neck portion 25 and is also recessed in the axial direction toward the second flange portion 23. Therefore, no matter what direction the burr protrudes from the corner of the peripheral edge of the straight passage 7a of the introduction passage 7 in the direction orthogonal to the axial direction, in the oblique direction, or further in the axial direction, the second It is possible to reliably prevent contact with the neck portion 25 by being received in the annular recess 37.

上記のようにして、取付座3に頭部20を介してクリップ10を取付けた状態で、同クリップ10の係止脚40を他方の部品2の係止孔2aに挿入し押し込むことにより、複数の弾性係止片43の係止段部43aが係止孔2aの裏側周縁に係合すると共に、第3フランジ部27が係止孔2aの表側周縁に弾性的に当接して、クリップ10を介して一方の部品1と他方の部品2とを連結することができる。   As described above, in a state where the clip 10 is attached to the attachment seat 3 via the head 20, the engaging leg 40 of the clip 10 is inserted into the engaging hole 2 a of the other component 2 and pushed into a plurality of parts. The engaging step portion 43a of the elastic engaging piece 43 engages with the back side periphery of the engaging hole 2a, and the third flange portion 27 elastically contacts the front side periphery of the engaging hole 2a. The one component 1 and the other component 2 can be connected via each other.
