Description

クリップclip
　この発明は、取付孔を有する被取付部材に使用するクリップに関し、特に自動車のインナーパネルにトリムボード等を係止するとともに、止水効果（シール性）も有するクリップに関するものである。 The present invention relates to a clip used for a member to be attached having a mounting hole, and more particularly to a clip that locks a trim board or the like on an inner panel of an automobile and also has a water stop effect (sealability).
　例えば、従来のクリップは、図８に示すように鍔部１とそれに続く軸部２と皿形スカート３及び弾性プレート４、弾性係合部５を備えた脚部６等から構成されている。このように構成されたクリップは、鍔部１にトリムボード等を取付た後、車体のインナーパネルに形成された取付孔に脚部６を挿入して固定する。このようにして、被取付部材と皿形スカートとの間のシールを行っていた（特許文献１）。
　また、他の従来例として、被取付部材とフランジ部との間に別部材であるシール部材を設置し、止水性を向上する例が提案されている（特許文献２）。 For example, as shown in FIG. 8, the conventional clip is composed of a flange portion 1, a shaft portion 2 subsequent thereto, a dish-shaped skirt 3, an elastic plate 4, a leg portion 6 having an elastic engagement portion 5, and the like. The clip configured in this manner is fixed by inserting a leg portion 6 into an attachment hole formed in the inner panel of the vehicle body after attaching a trim board or the like to the collar portion 1. In this way, the seal between the mounted member and the dish-shaped skirt was performed (Patent Document 1).
As another conventional example, there has been proposed an example in which a sealing member, which is a separate member, is installed between the attached member and the flange portion to improve the waterstop (Patent Document 2).
特公昭６３－２７５６７号公報Japanese Examined Patent Publication No. 63-27567 特開２００６－２２６３６８号公報JP 2006-226368 A
　しかし、図８に示すような従来のクリップは、皿形スカート３（フランジ部）の肉厚が薄く、低い剛性を有するものであった。特に、皿形スカート３のインナーパネル等と当接する先端部が薄く、止水性の低いものであった。したがって、自動車ドアのベルトライン等から雨水等が浸入した場合の防水性に問題が存在した。また、鍔部（頭部）に外力が加わった場合にも、フランジ部が変形し易く、溢水の虞が存在した。更に、皿形スカート（フランジ部）の肉厚が薄いために、クリップを成型する際に変形し易いと云う欠点が存在した。
　更にまた、フランジ部の剛性を高めるために、肉厚を厚くしようとしても、金型の構造上フランジ部の無理抜きが必要となり、必要とする肉厚まで厚くできないのが現状である。
　また、特許文献２に示す例にあっては、成型に際して金型の構造上、フランジ部の離型時に無理抜きが必要となり、ヨタリが発生する可能性が高かった。更に、経年劣化した際、シール部材とフランジ部の中心がズレて止水効果が低下する虞が存在した。また、別部材のシール部材を使用することは、コストの増加を招くものであった。 However, the conventional clip as shown in FIG. 8 has a thin plate-shaped skirt 3 (flange portion) and a low rigidity. In particular, the tip of the dish-shaped skirt 3 that is in contact with the inner panel or the like is thin and has a low water-stopping property. Therefore, there has been a problem in waterproofness when rainwater or the like enters from the belt line of the automobile door. Further, even when an external force is applied to the heel portion (head), the flange portion is easily deformed, and there is a risk of overflow. Furthermore, since the thickness of the dish-shaped skirt (flange) is thin, there is a drawback that it is easily deformed when the clip is molded.
Furthermore, in order to increase the rigidity of the flange portion, even if an attempt is made to increase the thickness, it is necessary to forcibly remove the flange portion due to the structure of the mold, and it is not possible to increase the thickness to the required thickness.
Further, in the example shown in Patent Document 2, due to the structure of the mold at the time of molding, it is necessary to forcibly remove the flange portion when releasing the mold, and there is a high possibility of occurrence of dripping. Furthermore, when the aging deteriorates, the center of the seal member and the flange portion may be misaligned and the water stop effect may be reduced. In addition, the use of a separate sealing member causes an increase in cost.
　この発明は、上記したような不都合を解消するためになされたもので、成型時の変形を防止するとともに、先端の周縁部の剛性を増して、止水性（シール性）を向上することのできるクリップを提供するものである。 The present invention has been made to solve the above-mentioned disadvantages, and can prevent deformation during molding and can increase the rigidity of the peripheral edge portion of the tip to improve water-stop (sealability). A clip is provided.
　本発明のクリップは、鍔部とフランジ部とから成る頭部と、前記頭部の下面に垂設され、被取付部材に形成された取付孔内に押し込まれて前記被取付部材を前記フランジ部との間で係止する係止部を備えた弾性係合脚を有する脚部とを有するクリップであって、前記フランジ部は、先端の周縁部を肉厚に形成したことを特徴とする。
　本発明のクリップにおいて、前記フランジ部の周縁部は、被取付部材と当接する当接面の中心に向かう延長線とフランジ部先端の内接線とが鋭角を成していることが好ましい。この場合、フランジ部の当接面と被取付部材との間に水が浸入した際に、水の表面張力で形成される水膜による止水効果が得られる。
　本発明のクリップにおいて、前記フランジ部の周縁部は、被取付部材と当接する当接面から略垂直に立ち上がって形成されたことが好ましい。この場合、フランジ部先端の肉厚を確保することができ、剛性を増すことができる。
　本発明のクリップにおいて、前記フランジ部は、球面状に湾曲形成されたことが好ましい。この場合、フランジ部の反力が増し、止水性能を向上することができる。また、クリップ本体にこじり荷重が加わった場合にも、耐力を増すことができる。
　本発明のクリップにおいて、前記脚部は、前記係止部を有する径方向に縮径可能な弾性係合脚と、中心柱から放射状に周方向に延設された突片が前記弾性係合脚の間にそれぞれ位置する横断面が十字型の軸部とを備えたことが好ましい。この場合、十字型空間の存在により弾性係合脚を撓み易くすることができる。したがって、被取付部材への挿入力を小さくすることができる。
　本発明のクリップにおいて、前記頭部は、間隔を有して配設された複数の鍔部を備え、鍔部と鍔部とを連結する軸部にトリムボード等を係止することが好ましい。この場合、取付部材に予めクリップを取り付けた後に組み立て作業を行うことができる。 The clip according to the present invention includes a head composed of a flange portion and a flange portion, and is suspended from a lower surface of the head portion and is pushed into a mounting hole formed in the mounted member so that the mounted member is inserted into the flange portion. And a leg portion having an elastic engagement leg provided with a locking portion for locking between the flange portion and the flange portion, wherein the peripheral edge portion at the tip is formed thick.
In the clip of the present invention, it is preferable that the peripheral portion of the flange portion has an acute angle between an extension line toward the center of the contact surface that contacts the attached member and an inscribed line at the tip of the flange portion. In this case, when water permeates between the contact surface of the flange portion and the mounted member, a water stop effect by a water film formed by the surface tension of water is obtained.
In the clip of the present invention, it is preferable that the peripheral edge portion of the flange portion is formed so as to rise substantially perpendicularly from the abutting surface that abuts the attached member. In this case, the thickness of the flange portion tip can be ensured, and the rigidity can be increased.
In the clip of the present invention, it is preferable that the flange portion is curved and formed in a spherical shape. In this case, the reaction force of the flange portion is increased and the water stop performance can be improved. Further, the proof stress can be increased even when a twisting load is applied to the clip body.
In the clip according to the aspect of the invention, the leg portion may include an elastic engagement leg having the locking portion that can be radially reduced in diameter, and a protruding piece that extends radially from the central column in the circumferential direction. It is preferable that the cross section located in each has a cross-shaped axial part. In this case, the elastic engagement leg can be easily bent due to the presence of the cross-shaped space. Therefore, the insertion force to the attached member can be reduced.
In the clip according to the present invention, it is preferable that the head portion includes a plurality of flange portions disposed at intervals, and a trim board or the like is locked to a shaft portion that connects the flange portions and the flange portions. In this case, the assembly work can be performed after the clip is previously attached to the attachment member.
　この発明によれば、鍔部とフランジ部とから成る頭部と、前記頭部の下面に垂設され、被取付部材に形成された取付孔内に押し込まれて前記被取付部材を前記フランジ部との間で係止する係止部を備えた弾性係合脚を有する脚部とを有するクリップであって、前記フランジ部は、先端の周縁部を肉厚に形成したので、フランジ部先端の剛性が増加して、被取付部材との間のシール性が向上する。また、成型時にフランジ部が反り返る等の変形を防止することができる。 According to the present invention, the head portion composed of the flange portion and the flange portion, and the bottom portion of the head portion is suspended, and is pushed into the mounting hole formed in the mounting member so that the mounting member is the flange portion. And a leg portion having an elastic engagement leg with a locking portion for locking between the flange portion and the flange portion, since the peripheral edge portion of the tip portion is formed thick, the rigidity of the flange portion tip end As a result, the sealing performance with the mounted member is improved. Further, it is possible to prevent deformation such as the flange portion warping during molding.

　本発明は、鍔部とフランジ部とから成る頭部と、頭部の下面に垂設され脚部を有するクリップであって、フランジ部の先端の周縁部を肉厚に形成したので、成型時の変形を防止するとともに、先端の周縁部の剛性を増して、シール性を向上することができる。 The present invention is a clip that has a head part composed of a flange part and a flange part and a leg part that is suspended from the lower surface of the head part, and the peripheral edge part at the tip of the flange part is formed thickly. Can be prevented, and the rigidity of the peripheral edge of the tip can be increased to improve the sealing performance.
　以下、一実施の形態を示す図面に基づいて本発明を詳細に説明する。図１は本発明の一実施の形態であるクリップの全体構成を示す斜視図、図２は本発明のクリップの正面図、図３は本発明のクリップの縦断面図である。ここで、本発明のクリップ１０は、第１の鍔部１１と第２の鍔部１２とフランジ部１３とから成る頭部１４と、前記頭部１４の下面に垂設され、被取付部材に形成された取付孔内に押し込まれて前記被取付部材を前記フランジ部１３との間で係止する係止部１５を備えた弾性係合脚１６を有する脚部１７とから構成されており、フランジ部１３は、先端の周縁部１８が肉厚に形成されている。 Hereinafter, the present invention will be described in detail with reference to the drawings showing an embodiment. FIG. 1 is a perspective view showing the overall configuration of a clip according to an embodiment of the present invention, FIG. 2 is a front view of the clip of the present invention, and FIG. 3 is a longitudinal sectional view of the clip of the present invention. Here, the clip 10 of the present invention is suspended from a head 14 composed of a first collar 11, a second collar 12, and a flange 13, and a lower surface of the head 14, and is attached to a mounted member. A leg portion 17 having an elastic engagement leg 16 provided with a locking portion 15 which is pushed into the formed mounting hole and locks the mounted member with the flange portion 13; As for the part 13, the peripheral part 18 of the front-end | tip is formed thickly.
　頭部１４は、図１～図３に示すように、所定の外径を有した中央の開口した円板状の第１の鍔部１１と、この第１の鍔部１１の下側の中心に連設され、第１の鍔部１１の外径よりも小径の頸部１９と、この頸部１９の下端外周に頸部１９を中心にして連設され、第１の鍔部１１よりも大径の第２の鍔部１２と、この第２の鍔部１２の下側に第２の鍔部１２の中心を中心として連設され、第２の鍔部１２よりも大径で略半球状のフランジ部１３とで構成されている。 As shown in FIGS. 1 to 3, the head portion 14 has a disc-shaped first flange portion 11 having a predetermined outer diameter and a center on the lower side of the first flange portion 11. The neck 19 having a diameter smaller than the outer diameter of the first collar 11 and the lower end outer periphery of the neck 19 centered on the neck 19, and more continuous than the first collar 11. A large-diameter second flange 12 and a lower side of the second flange 12 centered on the center of the second flange 12 and having a larger diameter than the second flange 12 and a substantially hemispherical shape. It is comprised with the shape flange part 13. FIG.
　図４は、本発明のクリップ１０のフランジ部先端を示す要部拡大断面図である。フランジ部１３の先端の周縁部１８は、それ以外の部位より肉厚に形成され、被取付部材２０と当接する当接面２１の中心に向かう延長線Ｒとフランジ部先端の内接線Ｌとが鋭角θを成している。また、フランジ部１３の周縁部１８の先端１８ａは、被取付部材２０と当接する当接面２１から略垂直に立ち上がって形成されている。したがって、フランジ部１３の先端部は、断面２次モーメントが大きく、剛性が高く構成されている。 FIG. 4 is an enlarged cross-sectional view of the main part showing the front end of the flange portion of the clip 10 of the present invention. The peripheral edge 18 at the front end of the flange portion 13 is formed thicker than other portions, and an extension line R toward the center of the contact surface 21 that contacts the attached member 20 and an inscribed line L at the front end of the flange portion. An acute angle θ is formed. Further, the front end 18 a of the peripheral edge portion 18 of the flange portion 13 is formed so as to rise substantially perpendicularly from the contact surface 21 that contacts the attached member 20. Therefore, the front end portion of the flange portion 13 is configured to have a large cross-sectional secondary moment and high rigidity.
　このように構成された周縁部１８において、フランジ部１３と被取付部材２０との間に水分が浸入した場合、被取付部材２０と当接する当接面２１の中心に向かう延長線Ｒとフランジ部先端の内接線Ｌとが鋭角θに形成されている為に、水分Ａｑが表面張力で丸くなり、当接面２１から漏れる虞がない。したがって、当接面２１に於けるシール性を向上することができる。また、クリップの製造時、射出成型する際の変形を防止できる。 In the peripheral portion 18 configured in this manner, when moisture enters between the flange portion 13 and the mounted member 20, the extension line R and the flange portion toward the center of the contact surface 21 that contacts the mounted member 20. Since the tip inscribed line L is formed at an acute angle θ, the moisture Aq is rounded by the surface tension, and there is no possibility of leakage from the contact surface 21. Therefore, the sealing performance on the contact surface 21 can be improved. Further, it is possible to prevent deformation during injection molding at the time of manufacturing the clip.
　次に、脚部１７は、図１～図３および図５に示すように、フランジ部１３（頭部１４）の下側に、フランジ部１３の中心を中心にして周方向に所定の等間隔を有して複数、例えば、４つ連設（垂設）され、径方向に弾性的に縮径可能な水平断面形状が扇型をした弾性係合脚１６と、フランジ部１３（頭部１４）の下側の中心に連設（垂設）され、中心柱２２から放射状に周方向に等間隔で延びる４つの突片２３が弾性係合脚１６の間にそれぞれ位置し、各突片２３の最外縁を連ねた仮想軸の直径が被取付部材２０に設けた係止孔２４の直径に満たない平断面形状が十字形状の支柱２５とで構成されている。また、各弾性係合脚１６は、図１～図３および図５に示すように、突片２３（支柱２５）に連結されている。 Next, as shown in FIG. 1 to FIG. 3 and FIG. 5, the legs 17 are arranged at regular intervals in the circumferential direction below the flange 13 (head 14) and centered on the center of the flange 13. A plurality of, for example, four (for example, four) continuous elastic legs 16 having a fan-shaped horizontal cross-sectional shape that can be elastically reduced in the radial direction, and a flange portion 13 (head portion 14). Four projecting pieces 23 that are connected (suspended) at the center on the lower side and extend radially from the central column 22 at equal intervals in the circumferential direction are positioned between the elastic engagement legs 16, respectively. A cross-sectional column 25 having a cross-sectional shape in which the diameter of the virtual axis that is connected to the outer edge is less than the diameter of the locking hole 24 provided in the mounted member 20 is configured. Each elastic engagement leg 16 is connected to the projecting piece 23 (the column 25) as shown in FIGS. 1 to 3 and FIG.
　次に、以上のように構成されたクリップ１０の使用状態を図６に従って説明する。図６において、被取付部材２０としてのドアインナーパネルには、クリップ１０を係合させるための係止孔２４が設けられている。この係止孔２４の直径は、４つの突片２３の最外側（最外縁）が形成する直径よりも僅かに大きな直径で、４つの弾性係合脚１６の最外側（最外縁）が形成する直径よりも僅かに小さな直径とされている。また、取付部材２６としてのトリムボードには、クリップ１０に取り付けるための取付孔としての鍵孔２７が設けられており、この鍵孔２７を介して、トリムボードをクリップ１０に取り付けた後、ドアインナーパネルに取り付ける。 Next, the usage state of the clip 10 configured as described above will be described with reference to FIG. In FIG. 6, the door inner panel as the mounted member 20 is provided with a locking hole 24 for engaging the clip 10. The diameter of the locking hole 24 is slightly larger than the diameter formed by the outermost sides (outermost edges) of the four projecting pieces 23, and the diameter formed by the outermost sides (outermost edges) of the four elastic engagement legs 16. The diameter is slightly smaller than that. The trim board as the attachment member 26 is provided with a key hole 27 as an attachment hole for attachment to the clip 10. After the trim board is attached to the clip 10 through the key hole 27, the door is opened. Attach to the inner panel.
　本発明のクリップにおいて、フランジ部１３の先端の周縁部１８は、それ以外の部位より肉厚に形成されているので、フランジ部の先端の剛性が増加して、被取付部材２０とより強固に圧接される。したがって、外力が加わった場合にも、被取付部材２０との間に隙間が生じる虞がなく、シール性の向上が可能である。 In the clip of the present invention, the peripheral edge portion 18 at the front end of the flange portion 13 is formed thicker than the other portions, so that the rigidity at the front end of the flange portion increases and becomes stronger with the attached member 20. Press contact. Therefore, even when an external force is applied, there is no possibility that a gap will be formed between the mounted member 20 and the sealing performance can be improved.
　図７は、本発明のクリップの水漏れ試験を示す説明図である。水漏れ試験は、水槽２８の側壁に係止孔２４を形成し、クリップ１０を取り付けた後に、係止孔２４から上に１００ｍｍの水を充填し、且つ頸部１９に負荷Ｗを加えた。この様な水漏れ試験を行っても、水が漏れることはなかった。つまり、フランジ部１３の先端の周縁部１８は、それ以外の部位より肉厚に形成されたので、剛性が増し、頸部１９に負荷を加えてもフランジ部１３の変形を殆どなくすことができる。また、被取付部材２０と当接する当接面２１の中心に向かう延長線Ｒとフランジ部先端の内接線Ｌとが鋭角θに形成されている為に、水分Ａｑが表面張力で丸くなり、当接面２１から漏れる虞がない。したがって、フランジ部１３に於ける充分なシール効果を達成することができた。 FIG. 7 is an explanatory view showing a water leak test of the clip of the present invention. In the water leak test, a locking hole 24 was formed in the side wall of the water tank 28, and after attaching the clip 10, 100 mm of water was filled up from the locking hole 24, and a load W was applied to the neck 19. Even if such a water leak test was conducted, water did not leak. That is, since the peripheral edge 18 at the tip of the flange portion 13 is formed thicker than other portions, the rigidity is increased, and even when a load is applied to the neck portion 19, deformation of the flange portion 13 can be almost eliminated. . Further, since the extension line R toward the center of the contact surface 21 that contacts the mounted member 20 and the inscribed line L at the front end of the flange portion are formed at an acute angle θ, the moisture Aq is rounded by the surface tension. There is no risk of leakage from the contact surface 21. Therefore, a sufficient sealing effect in the flange portion 13 could be achieved.
