Description

本発明は、給油ノズル差込部を構成して給油ノズルのフィラーパイプ内への挿入を案内する給油ノズル用ガイド装置に関する。   The present invention relates to a guide device for an oil supply nozzle that constitutes an oil supply nozzle insertion portion and guides insertion of the oil supply nozzle into a filler pipe.

図８は特許文献１に開示の車両の給油口構造を示し、（ａ）は給油ノズルをフィラーパイプの給油口側筒部に差し込んで給油している状態、（ｂ）は給油ノズルを案内するノズルガイド（本願の給油ノズル用ガイド装置に対応）を示している。同図の構造では、給油ノズルＮｚを差し込む筒部６と、給油ノズルＮｚから吐出された燃料Ｆを燃料タンク側へ送る供給経路を形成しているフィラーチューブ３と、筒部６に接続されて燃料タンクの燃料ベーパを排出するベントチューブ４と、筒部６に内設されて給油ノズルをフィラーパイプ３内へ案内するノズルガイド１０とを備えている。   FIG. 8 shows a vehicle fuel filler structure disclosed in Patent Document 1, wherein (a) shows a state in which a fuel nozzle is inserted into a filler pipe side cylinder portion of a filler pipe and fuel is supplied, and (b) guides the fuel nozzle. A nozzle guide (corresponding to the oil supply nozzle guide device of the present application) is shown. In the structure shown in the figure, the cylinder part 6 into which the fuel nozzle Nz is inserted, the filler tube 3 that forms a supply path for sending the fuel F discharged from the fuel nozzle Nz to the fuel tank side, and the cylinder part 6 are connected. A vent tube 4 for discharging the fuel vapor of the fuel tank and a nozzle guide 10 provided in the cylinder portion 6 for guiding the fuel nozzle into the filler pipe 3 are provided.

このノズルガイド１０は分割体１１，１２からなる。分割体１１には可動爪１１ｂ及び壁部１１ｃが設けられ、分割体１０には押圧部１２ｅが設けられている。そして、可動爪１１は、分割体１１と分割体１２とが相対移動させると押圧部１２ｅによって押圧変形される。一方、筒部６には筒体２の段差端縁で形成された被係合部２ｃが設けられている。そして、ノズルガイド１０は、筒部６内で、可動爪１１ｂ付きの分割体１１と押圧部１２ｅ付きの分割体１２とを相対移動して、可動爪１１ｂを押圧部１２ｅにて押圧変位して被係合部２ｃに係合することにより筒内に固定される。   The nozzle guide 10 includes divided bodies 11 and 12. The divided body 11 is provided with a movable claw 11b and a wall portion 11c, and the divided body 10 is provided with a pressing portion 12e. And the movable nail | claw 11 will be press-deformed by the press part 12e, if the division body 11 and the division body 12 move relatively. On the other hand, the cylindrical portion 6 is provided with an engaged portion 2 c formed by a step edge of the cylindrical body 2. Then, the nozzle guide 10 relatively moves the divided body 11 with the movable claw 11b and the divided body 12 with the pressing portion 12e within the cylindrical portion 6, and the movable claw 11b is pressed and displaced by the pressing portion 12e. By being engaged with the engaged portion 2c, it is fixed in the cylinder.

すなわち、ノズルガイド１０の組み付けに際しては、まず、分割体１１を筒部６内の奥側に差し込み、次いで分割体１２を筒部６内に差し込む。この場合、分割体１２を筒部６内に差し込むと、分割体１１，１２同士が差込方向Ｉに相対的に近接し、分割体１１の可動爪１１ｂ及び壁部１１ｃが分割体１２の切欠部１２ｄに挿入される。このとき、切欠部１２ｄの開放側の拡開部１２ｆ，１２ｇが可動爪１１ｂのガイドとなるため、可動爪１１ｂを切欠部１２ｄに円滑に移動可能となる。そして、可動爪１１ｂ及び壁部１１ｃは、切欠部１２ｄの内壁部１２ｅにより筒外側に押し出される。これにより、可動爪１１ｂの係止突起１１ｄと壁部１１ｃの側壁部１１ｇの先端部分とが、被係合部２ｃに係合し、分割体１１が筒部６内に係合される。同時に、分割体１１，１２同士は、分割体１２を差込方向Ｉに押し込むことで、係合機構１３を構成している分割体１１側の開口部１２ｈと分割体１２側の突起１２ｉとの係合により一体化される。   That is, when the nozzle guide 10 is assembled, first, the divided body 11 is inserted into the inner side of the cylindrical portion 6, and then the divided body 12 is inserted into the cylindrical portion 6. In this case, when the divided body 12 is inserted into the cylindrical portion 6, the divided bodies 11 and 12 are relatively close to each other in the insertion direction I, and the movable claw 11 b and the wall portion 11 c of the divided body 11 are notched in the divided body 12. It is inserted into the part 12d. At this time, since the widened portions 12f and 12g on the open side of the notch 12d serve as a guide for the movable claw 11b, the movable claw 11b can be smoothly moved to the notch 12d. And the movable nail | claw 11b and the wall part 11c are extruded to the cylinder outer side by the inner wall part 12e of the notch part 12d. As a result, the locking projection 11d of the movable claw 11b and the tip end portion of the side wall portion 11g of the wall portion 11c are engaged with the engaged portion 2c, and the divided body 11 is engaged in the cylindrical portion 6. At the same time, the divided bodies 11 and 12 push the divided body 12 in the insertion direction I, so that the opening 12h on the divided body 11 side and the projection 12i on the divided body 12 side constituting the engagement mechanism 13 are formed. It is integrated by engagement.

Centering on the tubular portion 13 is possible.

筒状部１３は、筒内１４が円筒状に形成にされ、外周が一部を平らな板状部１６に形成し、板状部１６及び導入部１０と反対側の端部である径小の配置部１７を除いた周囲部に筒方向の横リブ１５ａ及び周方向のリブ１５ｂを形成している。このうち、板状部１６は、図１のごとくベントチューブ４の出口側端部４ａと対向した状態で端部４ａと隙間を保って配置される。板状部１６には、仮止め用の規制リブ１６ａ，１６ｂが後端側に突設されている。各規制リブ１６ａ，１６ｂは、所定間隔を保っており、図３（ｃ）のごとく配置部１７に嵌合されたグロメット２を規制リブ１６ａと１６ｂとの間に挟み込んだ状態で仮止め可能となっている。   The cylindrical portion 13 is formed in a cylindrical shape in the cylinder 14, and a part of the outer periphery is formed into a flat plate-shaped portion 16, and the small diameter is the end opposite to the plate-shaped portion 16 and the introduction portion 10. The horizontal ribs 15a in the cylindrical direction and the ribs 15b in the circumferential direction are formed in the peripheral part excluding the arrangement part 17 of FIG. Among these, the plate-like portion 16 is arranged with a gap from the end portion 4a in a state of facing the outlet side end portion 4a of the vent tube 4 as shown in FIG. The plate-like portion 16 is provided with restricting ribs 16a and 16b for temporary fixing on the rear end side. The regulating ribs 16a and 16b are kept at a predetermined interval, and can be temporarily fixed in a state where the grommet 2 fitted to the arrangement portion 17 is sandwiched between the regulating ribs 16a and 16b as shown in FIG. It has become.

配置部１７は、図４（ｃ）のごとく端部から離れる側の段差により第１係止部１７ａを形成しており、グロメット２を第１係止部１７ａに当接することにより相対的な移動を規制可能となっている。配置部１７の後端外周は、一段径大に形成されており、その径大部に設けられた複数（この例では板状部１６の両側近くと、板状部１６と対向する下側の３箇所）の台座部１９と、各台座部１９に連接した状態に設けられている第２係止部１８とを有している。この例では、配置部１７の後端外周を径大部にし、その径大部のうち、台座部１９同士の間の内側部分を切り欠くことにより第２係止部１８を形成している。   As shown in FIG. 4C, the arrangement portion 17 forms a first locking portion 17a with a step on the side away from the end portion, and the grommet 2 is moved relatively by contacting the first locking portion 17a. Can be regulated. The outer periphery of the rear end of the arrangement portion 17 is formed to be one step larger in diameter, and a plurality of (in this example, near both sides of the plate-like portion 16 and on the lower side facing the plate-like portion 16 provided in the large-diameter portion. (3 places) pedestal portions 19 and second locking portions 18 provided in a state of being connected to each pedestal portion 19. In this example, the outer periphery of the rear end of the arrangement portion 17 is a large diameter portion, and the second locking portion 18 is formed by cutting out the inner portion between the pedestal portions 19 among the large diameter portion.

一方、グロメット２は、図３及び図７に示されるごとく筒状部１３の外周に嵌合される環状部２０と、環状部２０に突設されて互いに間隔２５を保っている複数の弾性脚部２３とからなる。環状部２０は、一部が板状部１６に対応した直線状の片部２１に形成されている。片部２１は、規制リブ１６ａと１６ｂとの間に挟み込まれる太さである。各脚部２３は、環状部２０の端面に径小首部２２を介して突出されて、先端内側に段差状の係止肩部２４を形成している。なお、片部２１には脚部２３が設けられていない。   On the other hand, the grommet 2 includes an annular portion 20 fitted to the outer periphery of the tubular portion 13 as shown in FIGS. 3 and 7 and a plurality of elastic legs that protrude from the annular portion 20 and maintain a distance 25 from each other.

The piece portion 21 has a thickness that is sandwiched between the regulating ribs 16a and 16b. Each leg portion 23 protrudes from the end surface of the annular portion 20 via a small-diameter neck portion 22 to form a stepped locking shoulder portion 24 inside the tip. Note that the leg portion 23 is not provided on the piece portion 21.

（組込操作）以上のグロメット２は、ガイド本体１に仮止めされた状態で給油口側筒部３０に組込操作される。
（１）本発明のガイド装置は、ガイド本体１及びグロメット２が車体組立ラインないしはフィラーパイプ回りの組立ラインに投入される前の段階で、グロメット２がガイド本体１に対し仮組み付けされた状態で管理されたり搬送されるため取扱性に優れている。勿論、仮組み付け操作はワンタッチ操作で行える。すなわち、作業者は、例えば、グロメット２を持って、環状部２０をガイド本体１の配置部１７の後端に対向配置し、かつ嵌合した状態から押し込める。すると、グロメット２は、片部２１が規制リブ１６ａを弾性的に乗り越えて、規制リブ１６ａと規制リブ１６ｂとの間に挟み込まれてガイド本体１に仮組み付けされる。図３は、このようにしてグロメット２がガイド本体１の筒状部１３に設けられた仮止め位置に配置された仮組み付け状態（以下、この状態のガイド装置をグロメット付きガイド本体という）を示している。 (Assembly Operation) The grommet 2 described above is assembled into the filler port side cylinder portion 30 while being temporarily fixed to the guide body 1.
(1) The guide device of the present invention is in a state where the grommet 2 is temporarily assembled to the guide body 1 at a stage before the guide body 1 and the grommet 2 are put into the vehicle body assembly line or the assembly line around the filler pipe. It is easy to handle because it is controlled and transported. Of course, the temporary assembly operation can be performed by a one-touch operation. That is, for example, the operator holds the grommet 2 and presses the annular portion 20 from the fitted state by placing the annular portion 20 opposite to the rear end of the placement portion 17 of the guide body 1. Then, the grommet 2 is temporarily attached to the guide body 1 by being sandwiched between the regulating rib 16a and the regulating rib 16b, with the piece portion 21 elastically moving over the regulating rib 16a. FIG. 3 shows a temporarily assembled state in which the grommet 2 is thus disposed at the temporary fixing position provided on the cylindrical portion 13 of the guide body 1 (hereinafter, the guide device in this state is referred to as a guide body with a grommet). ing.

（２）本発明のガイド装置は、以上の仮組み付け状態で給油口側筒部３０にワンタッチ操作により組み込まれる。この作業では、図５（ｂ）に示したごとくグロメット付きガイド本体１を、板状部１６がベントチューブ４の出口側端部４ａを向くように位置だして、筒部３０内にグロメット２側より挿入すると、導入部１０を構成している翼部１１の先端側がリング状ボス３３に当接する。更に、グロメット付きガイド本体１を筒部３０内に押し入れると、各翼部１１が縮径方向に変形してボス３３を通過し、完全に通過すると元の形状に復元される。また、グロメット付きガイド本体１は、図３（ｃ）に示したごとく更に筒部３０の奥側に移動されると、各脚部２３が筒部内の突起３５と当たった後、縮径方向に変形しながら突起３５が首部２４に係合される。 (2) The guide device of the present invention is incorporated into the filler port side cylinder portion 30 by a one-touch operation in the above temporarily assembled state. In this operation, as shown in FIG. 5B, the guide body 1 with grommet is positioned so that the plate-like portion 16 faces the outlet side end portion 4 a of the vent tube 4, and the grommet 2 side is placed in the cylindrical portion 30. When inserted further, the tip side of the wing part 11 constituting the introduction part 10 comes into contact with the ring-shaped boss 33. Further, when the guide main body 1 with grommet is pushed into the cylindrical portion 30, each wing portion 11 is deformed in the diameter reducing direction, passes through the boss 33, and is restored to its original shape when completely passed. When the guide body 1 with grommet is further moved to the back side of the cylindrical portion 30 as shown in FIG. 3C, each leg portion 23 comes into contact with the projection 35 in the cylindrical portion, and then in the reduced diameter direction. The protrusion 35 is engaged with the neck portion 24 while being deformed.

（３）この構造では、更にガイド本体１が筒部３０の奥側に押されると、グロメット２が各突起３５に首部２４を係合し、それにより筒部３０に対して位置規制ないしは移動不能な状態となっているため、ガイド本体１だけが単独で奥側に移動される。すると、図１及び図４（ｃ）に示したごとく、ガイド本体１は、筒部３０に位置固定されているグロメット側環状部２０の外端面に第１係止部１７ａが当接して移動が規制される。この過程では、グロメットの脚部２３が内面に圧接する台座部１９より拡径方向に変形され、グロメットの係止肩部２４が第２係止部２８と係合される。 (3) In this structure, when the guide main body 1 is further pushed to the inner side of the cylindrical portion 30, the grommet 2 engages the neck portion 24 with each protrusion 35, thereby restricting the position or movement of the cylindrical portion 30. Therefore, only the guide body 1 is moved to the back side alone. Then, as shown in FIG. 1 and FIG. 4C, the guide body 1 is moved by the first locking portion 17 a coming into contact with the outer end surface of the grommet-side annular portion 20 fixed to the cylindrical portion 30. Be regulated. In this process, the leg portion 23 of the grommet is deformed in the diameter-expanding direction from the pedestal portion 19 pressed against the inner surface, and the locking shoulder portion 24 of the grommet is engaged with the second locking portion 28.

すなわち、台座部１９は、グロメット２が配置部１７に沿って相対的に移動されて第１係止部１７ａに当たった本止め位置で、脚部２３を拡開方向ないしは筒状部径方向に変形し、それにより突起３５に対する首部２２の係合を解除不能にする。第２係止部１８は、図４（ｃ）の拡大図のごとくグロメット２が前記の本止め位置に配置されたとき、脚部２３の内側に設けられた係止肩部２４と係合してグロメット２の配置部１７から外れる方向への移動を不能にする。   That is, the pedestal portion 19 moves the leg portion 23 in the expanding direction or the cylindrical portion radial direction at the main locking position where the grommet 2 is relatively moved along the arrangement portion 17 and hits the first locking portion 17a. Deforms, thereby disengaging the neck 22 from the projection 35. The second locking portion 18 engages with a locking shoulder portion 24 provided on the inner side of the leg portion 23 when the grommet 2 is disposed at the main locking position as shown in the enlarged view of FIG. Thus, the movement of the grommet 2 in the direction away from the arrangement portion 17 is disabled.

(４)、従って、以上のガイド装置は、筒部３０に対してグロメット付きガイド本体１を給油口側筒部３０内へ挿入操作することによりグロメット側首部２２と筒部側突起３５との係合により固定される。この係合状態は、ガイド本体１の筒部３０内への更なる挿入によりグロメット２を配置部１７の仮止め位置から本止め位置に切り換えて解除不能となる。これらは、ガイド装置の簡易性を維持しつつ、良好な組込操作性及び安定係合性（過大な衝撃を受けても係合解除の虞をなくすること）を確実に得られるようにする。 (4) Therefore, in the above guide device, the grommet-side neck portion 22 and the cylinder-side protrusion 35 are engaged by inserting the grommet-equipped guide body 1 into the oil filler-side cylinder portion 30 with respect to the cylinder portion 30. It is fixed by the combination. This engagement state cannot be released by switching the grommet 2 from the temporary stop position of the placement portion 17 to the final stop position by further insertion of the guide body 1 into the cylindrical portion 30. These make it possible to reliably obtain good assembling operability and stable engagement (to eliminate the possibility of disengagement even under excessive impact) while maintaining the simplicity of the guide device. .

また、以上のガイド装置は、グロメット２がガイド本体１の本止め位置に相対的に移動されたとき、環状部２０が筒状部側第１係止部１７ａに当接してガイド本体１の挿入を規制したり、脚部２３の内側に設けられた係止肩部２４が筒状部側第２係止部１８に係合するため、ガイド本体１に対するグロメット２の一体化を全体の長さを抑えながら精度よく行える。しかも、以上のガイド装置は、筒部３０内に固定された状態において、ガイド本体１が各翼部１１が筒部内周面３０ａに圧接していること、筒状部１３が筒部内の受け面３４に支持されていることからも上記した安定係合性に優れている。   Further, in the above guide device, when the grommet 2 is relatively moved to the main stop position of the guide body 1, the annular portion 20 comes into contact with the cylindrical portion side first locking portion 17a and the guide body 1 is inserted. The locking shoulder 24 provided on the inner side of the leg portion 23 engages with the cylindrical portion side second locking portion 18, so that the grommet 2 is integrated with the guide body 1 over the entire length. Can be performed with high accuracy. In addition, in the guide device described above, in the state where the guide body 1 is fixed in the cylindrical portion 30, the guide body 1 is such that each wing portion 11 is in pressure contact with the cylindrical inner peripheral surface 30a and the cylindrical portion 13 is a receiving surface in the cylindrical portion. 34, the above-described stable engagement is excellent.

更に、以上のガイド装置では、給油口側筒部３０内において、ベントチューブ４から上昇される燃料ペーパをガイド本体１の板状部１６との間に形成された隙間から、ガイド本体１の翼部１１同士の間の間隔を通って流れ易くし、それにより燃料ペーパを筒部３０の奥側つまりフィラーパイプ３の燃料供給通路内に導入され難くすることができる。   Further, in the guide device described above, the fuel paper that is lifted from the vent tube 4 in the filler port side cylinder portion 30 passes through the gap formed between the plate-like portion 16 of the guide body 1 and the blades of the guide body 1. It is possible to facilitate flow through the space between the portions 11, thereby making it difficult to introduce the fuel paper into the back side of the cylindrical portion 30, that is, into the fuel supply passage of the filler pipe 3.

なお、本発明のガイド装置は、請求項で特定される構成を備えておればよく、細部は形態例を参考にして変更したり展開可能なものである。その例としては、燃料ペーパをフィラーパイプ３の燃料供給通路内により導入され難くするため、板状部１６のうちベントチューブ側端部４ａより奥側に、フィラーパイプ３側と端部４ａ側とを仕切るような立壁などを設けることである。   In addition, the guide apparatus of this invention should just be equipped with the structure specified by a claim, and a detail can be changed and developed with reference to the form example. As an example, in order to make it difficult for the fuel paper to be introduced into the fuel supply passage of the filler pipe 3, the filler pipe 3 side and the end portion 4 a side are disposed on the back side of the vent tube side end portion 4 a of the plate-like portion 16. It is to provide a standing wall or the like that partitions.
