Description

本発明は、燃料タンクに取り付けられ、燃料供給管等の配管の接続に用いられる管継手に関する。   The present invention relates to a pipe joint that is attached to a fuel tank and used for connecting a pipe such as a fuel supply pipe.

燃料タンクに対して燃料供給管等の配管を接続するために、燃料タンクに予め管継手を設けておくことが、従来から一般的に行われている。   In order to connect a pipe such as a fuel supply pipe to the fuel tank, it has been generally performed to provide a pipe joint in advance in the fuel tank.

従来のこの種の管継手１００は、図５（特許文献１の図３に基づく）に示すように、燃料タンクの壁面に設けられた開口部の周縁に当接されるフランジ部１２０と、当該フランジ部１２０から燃料タンクの外側に突出するように設けられる接続管部１３０と、を備えている。そして、接続管部１３０の内周側に、金属製の補強用カラー１６０が設けられている。   As shown in FIG. 5 (based on FIG. 3 of Patent Document 1), a conventional pipe joint 100 of this type includes a flange portion 120 that is in contact with a peripheral edge of an opening provided on a wall surface of a fuel tank, And a connecting pipe part 130 provided so as to protrude from the flange part 120 to the outside of the fuel tank. A metal reinforcing collar 160 is provided on the inner peripheral side of the connecting pipe portion 130.

一般に、燃料供給管等の配管Ｐを接続管部１３０に接続する際には、ホースクランプやホースバンド等の固定具Ｈを用いた締付固定が採用される。そして、配管Ｐの抜け外れを防止するために、締付固定の締付力は比較的強固に設定される。そのため、接続管部１３０の破損等を回避するために、金属製の補強用カラー１６０が用いられているのである。   In general, when connecting the pipe P such as the fuel supply pipe to the connecting pipe portion 130, tightening and fixing using a fixing tool H such as a hose clamp or a hose band is employed. In order to prevent the piping P from coming off, the tightening force for tightening and fixing is set relatively firmly. For this reason, a metal reinforcing collar 160 is used in order to avoid damage to the connecting pipe portion 130 and the like.

特開２０１０−１１１３１６JP 2010-111316 A 特許４２５３６２０Patent 4253620

金属製の補強用カラー１６０は、確かに、接続管部１３０の強度を補強するのに十分効果的である。しかしながら、金属製であるために、コストが高い。また、金属製の補強用カラー１６０を固定するためには熱カシメ工程等が必要であり、そのための専用設備が必要である。一方、樹脂によって補強用カラー１６０を製造しても、強度的に十分なものができない。   The metal reinforcing collar 160 is certainly effective enough to reinforce the strength of the connecting pipe portion 130. However, since it is made of metal, the cost is high. Further, in order to fix the metal reinforcing collar 160, a heat caulking process or the like is necessary, and dedicated equipment for that is required. On the other hand, even if the reinforcing collar 160 is made of resin, it cannot be sufficiently strong.

本発明は、以上の知見に基づいて創案されたものである。本発明の目的は、金属製の補強用カラーを用いることなく、接続管部において十分な強度を有する燃料タンク用管継手を提供することである。   The present invention has been created based on the above findings. An object of the present invention is to provide a fuel tank pipe joint having a sufficient strength in a connecting pipe portion without using a metal reinforcing collar.

本発明は、燃料タンクの壁面に設けられた開口部の周縁に当接されるフランジ部と、前記フランジ部から燃料タンクの外側に突出するように設けられる接続管部と、を備え、前記接続管部の内側に、補強用リブが渡されていることを特徴とする燃料タンク用管継手である。   The present invention includes a flange portion that is in contact with a peripheral edge of an opening portion provided on a wall surface of a fuel tank, and a connection pipe portion that is provided so as to protrude from the flange portion to the outside of the fuel tank. A fuel tank pipe joint characterized in that a reinforcing rib is provided inside the pipe part.

本発明によれば、接続管部の内側に補強用リブが渡されていることにより、金属製の補強用カラーを用いずとも、接続管部において十分な強度を実現することができる。特に、本件発明者による知見によれば、樹脂製の補強用リブであっても、接続管部において十分な強度を実現することができる。従って、金属製の補強用カラーを用いる従来の燃料タンク用管継手と比較して、コストの面で非常に有利である。   According to the present invention, since the reinforcing rib is provided inside the connecting pipe portion, sufficient strength can be realized in the connecting pipe portion without using a metal reinforcing collar. In particular, according to the knowledge of the present inventors, even a resin reinforcing rib can achieve a sufficient strength in the connecting pipe portion. Therefore, it is very advantageous in terms of cost as compared with a conventional fuel tank fitting using a metal reinforcing collar.

補強用リブは、接続管部の中心軸を中心とした放射線上に延びる放射線部と、接続管部の内側断面と略同心状の環状部と、を有するように設けられることが好ましい。この場合、補強用リブの配置バランスが良く補強強度の点で好適であるだけでなく、接続管部内の流路抵抗も低いという利点が得られる。更にこの場合、アンチサイフォン機能をも奏することができる。   The reinforcing rib is preferably provided so as to have a radiation part extending on the radiation around the central axis of the connection pipe part, and an annular part substantially concentric with the inner cross section of the connection pipe part. In this case, not only is the arrangement balance of the reinforcing ribs good and the reinforcing strength is favorable, but also the advantage that the flow resistance in the connecting pipe portion is low is obtained. Furthermore, in this case, an anti-siphon function can also be achieved.

もっとも、少なくとも本願出願の時点においては、補強用リブが接続管部の中心軸を中心とした放射線上に延びる放射線部のみからなるものも、本発明の範囲に含まれる。   However, at least at the time of filing the present application, it is also included in the scope of the present invention that the reinforcing rib is composed only of a radiation portion extending on the radiation centering on the central axis of the connecting pipe portion.

なお、接続管部は、フランジ部から燃料タンクの内側にも突出していてよい。この場合、補強用リブは、フランジ部に対して燃料タンクの外側の領域の接続管部の内側に設けられることが好ましい。ホースクランプやホースバンド等の固定具は、フランジ部に対して燃料タンクの外側の領域の接続管部に対して適用されるからである。また、接続管部がフランジ部から燃料タンクの内側にも突出している場合、当該内側の領域の接続管部の内側に、弁装置が設けられ得る。弁装置としては、例えば公知のフラップ弁装置が適用され得る。   The connecting pipe portion may also protrude from the flange portion to the inside of the fuel tank. In this case, the reinforcing rib is preferably provided inside the connecting pipe portion in the region outside the fuel tank with respect to the flange portion. This is because fixing tools such as a hose clamp and a hose band are applied to the connecting pipe portion in the region outside the fuel tank with respect to the flange portion. Further, when the connecting pipe portion protrudes also from the flange portion to the inside of the fuel tank, a valve device can be provided inside the connecting pipe portion in the inner region. As the valve device, for example, a known flap valve device can be applied.

また、接続管部は、フランジ部と一体の外側管部と、外側管部に対して結合（嵌合、溶着、インサート成形等）される内側管部と、を有していることが好ましい。この場合、補強用リブは、内側管部の内部に設けられる。このような場合、燃料タンクに対してフランジ部と一体の外側管部を取り付ける際に内側管部が直接には関与しないため、部品点数が多く高価になりがちな内側管部を損傷してしまうというおそれが顕著に軽減される。   Moreover, it is preferable that a connection pipe part has an outer side pipe part integral with a flange part, and an inner side pipe part couple | bonded (fitting, welding, insert molding, etc.) with respect to an outer side pipe part. In this case, the reinforcing rib is provided inside the inner tube portion. In such a case, when the outer pipe unit integrated with the flange part is attached to the fuel tank, the inner pipe unit is not directly involved, and therefore, the inner pipe unit which tends to be expensive due to a large number of parts is damaged. Is significantly reduced.

本発明によれば、接続管部の内側に補強用リブが渡されていることにより、金属製の補強用カラーを用いずとも、接続管部において十分な強度を実現することができる。特に、本件発明者による知見によれば、樹脂製の補強用リブであっても、接続管部において十分な強度を実現することができる。従って、金属製の補強用カラーを用いる従来の燃料タンク用管継手と比較して、コストの面で非常に有利である。   According to the present invention, since the reinforcing rib is provided inside the connecting pipe portion, sufficient strength can be realized in the connecting pipe portion without using a metal reinforcing collar. In particular, according to the knowledge of the present inventors, even a resin reinforcing rib can achieve a sufficient strength in the connecting pipe portion. Therefore, it is very advantageous in terms of cost as compared with a conventional fuel tank fitting using a metal reinforcing collar.

FIG. 2 is a longitudinal sectional view taken along line BB in FIG. FIG. 3 is a schematic plan view of the fuel tank fitting of FIG.

特に図１及び図２に示すように、本実施の形態の燃料タンク用管継手１０は、不図示の燃料タンクの壁面に設けられた開口部の周縁に当接されるフランジ部２０と、フランジ部２０から燃料タンクの外側（図２の上側）に突出するように設けられた接続管部３０と、を備えている。   In particular, as shown in FIGS. 1 and 2, the fuel tank fitting 10 according to the present embodiment includes a flange portion 20 that is in contact with a peripheral edge of an opening provided on a wall surface of a fuel tank (not shown), and a flange. And a connecting pipe portion 30 provided so as to protrude from the portion 20 to the outside of the fuel tank (upper side in FIG. 2).

本実施の形態の接続管部３０は、フランジ部２０に対して燃料タンクの内側（図２の上側）にも突出している。そして、接続管部３０は、図２に示すように、フランジ部２０の一部を構成する小フランジ２１と一体の外側管部３１と、外側管部３１の燃料タンク内側端部（図２の下側端部）を挟み込むようにして嵌合されるようになっている内側管部３２（フラップケースの差込部とも称される）と、を有している。   The connecting pipe portion 30 of the present embodiment also protrudes from the inside of the fuel tank (upper side in FIG. 2) with respect to the flange portion 20. As shown in FIG. 2, the connecting pipe part 30 includes an outer pipe part 31 integrated with a small flange 21 constituting a part of the flange part 20, and a fuel tank inner end part (see FIG. 2). And an inner tube portion 32 (also referred to as an insertion portion of the flap case) that is fitted so as to sandwich the lower end portion).

本実施の形態では、更に、小フランジ２１を覆う大フランジ２３と一体のハウジング部３３（取付部とも称される）が、外側管部３１に対して、性質が異なる２種類の樹脂材料を２色成形することによって一体に形成されている。より具体的には、小フランジ２１を含む外側管部３１がポリアミドで形成され、大フランジ２３を含むハウジング部３３がポリエチレンで形成され、両者が一体化されている。   In the present embodiment, the housing portion 33 (also referred to as an attachment portion) integral with the large flange 23 covering the small flange 21 is further provided with two types of resin materials having different properties with respect to the outer tube portion 31. It is integrally formed by color molding. More specifically, the outer pipe portion 31 including the small flange 21 is formed of polyamide, the housing portion 33 including the large flange 23 is formed of polyethylene, and both are integrated.

そして、フランジ部２０に対して燃料タンクの外側の領域の縦方向の略中央位置の内側管部３２の内側に、本発明の特徴である補強用リブ６０が渡されている。本実施の形態の補強用リブ６０は、具体的には、図２及び図３に示すように、内側管部３２の中心軸を中心とした放射線上に延びる６本の放射線部６１と、内側管部３２の内側断面と略同心状の環状部６２と、を有している。また、図２に示すように、補強用リブ６０の６本の放射線部６１の各々は、内側管部３２の中心軸に近い部分より内側管部３２の中心軸から遠い部分の方が高さが末広がり状に２倍程度にまで高くなっている（幅に関しては、図３に示す通り、一様である）。   A reinforcing rib 60 that is a feature of the present invention is provided inside the inner pipe portion 32 at a substantially central position in the vertical direction in the region outside the fuel tank with respect to the flange portion 20. Specifically, as shown in FIGS. 2 and 3, the reinforcing rib 60 of the present embodiment includes six radiation portions 61 extending on the radiation around the central axis of the inner tube portion 32, and an inner side. An inner cross section of the pipe portion 32 and an annular portion 62 that is substantially concentric are provided. Further, as shown in FIG. 2, each of the six radiation parts 61 of the reinforcing rib 60 is higher in a part far from the central axis of the inner pipe part 32 than in a part near the central axis of the inner pipe part 32. Is widened in a divergent shape to about twice (the width is uniform as shown in FIG. 3).

本実施の形態では、ハウジング部３３、外側管部３１、内側管部３２、補強用リブ６０の全てが樹脂製である。具体的には、ハウジング部３３は、燃料タンクに対する溶着が容易であるように、燃料タンクと同様の樹脂、例えばポリエチレン（ＰＥ）等のポリオレフィン系の合成樹脂、で形成される。一方、内側管部３２と補強用リブ６０とは、強度が高く耐燃料油性に優れる樹脂、例えばポリオキシメチレン（ＰＯＭ）、ポリアミド（ＰＡ）、ポリブチレンテレフタレート（ＰＢＴ）等で形成される。   In the present embodiment, the housing part 33, the outer pipe part 31, the inner pipe part 32, and the reinforcing rib 60 are all made of resin. Specifically, the housing part 33 is formed of the same resin as the fuel tank, for example, a polyolefin-based synthetic resin such as polyethylene (PE), so that the welding to the fuel tank is easy. On the other hand, the inner pipe portion 32 and the reinforcing rib 60 are formed of a resin having high strength and excellent fuel oil resistance, such as polyoxymethylene (POM), polyamide (PA), polybutylene terephthalate (PBT), and the like.

また、本実施の形態では、フランジ部２０に対して燃料タンクの内側の領域の内側管部３２の内側に、弁装置７０が設けられている。本実施の形態の弁装置７０は、公知のフラップ弁装置であり、それ自体の詳細な説明は省略する。   In the present embodiment, the valve device 70 is provided inside the inner pipe portion 32 in the region inside the fuel tank with respect to the flange portion 20. The valve device 70 of the present embodiment is a known flap valve device, and detailed description thereof is omitted.

次に、以上のような本実施の形態の燃料タンク用管継手１０の作用について説明する。   Next, the operation of the fuel tank fitting 10 of the present embodiment as described above will be described.

まず、補強用リブ６０及び弁装置７０を有する内側管部３２が、図２に示すように、外側管部３１に対して嵌合される。本実施の形態では、前述の通り、外側管部３１とハウジング部３３とが２色成形によって予め一体形成されていて、ハウジング部３３の大フランジ２３と外側管部３１の小フランジ２１とがフランジ部２０を形成している。このフランジ部２０が、燃料タンクの壁面に設けられた開口部の周縁に取り付けられ、ハウジング部３３が燃料タンクの壁面に溶着される。このように、本実施の形態の燃料タンク用管継手１０は、金属部材の熱カシメのような特殊な工程を要することなく、燃料タンクに容易に取り付けることができる。   First, the inner tube portion 32 having the reinforcing rib 60 and the valve device 70 is fitted to the outer tube portion 31 as shown in FIG. In the present embodiment, as described above, the outer tube portion 31 and the housing portion 33 are integrally formed in advance by two-color molding, and the large flange 23 of the housing portion 33 and the small flange 21 of the outer tube portion 31 are flanged. Part 20 is formed. The flange portion 20 is attached to the periphery of the opening provided on the wall surface of the fuel tank, and the housing portion 33 is welded to the wall surface of the fuel tank. Thus, the fuel tank fitting 10 of the present embodiment can be easily attached to the fuel tank without requiring a special process such as heat caulking of the metal member.

以上のようにして燃料タンクに取り付けられた本実施の形態の燃料タンク用管継手１０は、内側管部３２の内側に補強用リブ６０が渡されていることにより、金属製の補強用カラーを用いずとも、接続管部３０において十分な強度を実現することができる。特に、本実施の形態では、補強用リブ６０が樹脂製であるにも拘わらず接続管部３０において十分な強度を実現するため、金属製の補強用カラーを用いる従来の燃料タンク用管継手と比較してコストの面で非常に有利である。   In the fuel tank pipe joint 10 of the present embodiment attached to the fuel tank as described above, the reinforcing rib 60 is passed inside the inner pipe portion 32, so that the metal reinforcing collar can be used. Even if it does not use, sufficient intensity | strength can be implement | achieved in the connection pipe part 30. FIG. In particular, in the present embodiment, in order to realize sufficient strength in the connecting pipe portion 30 even though the reinforcing rib 60 is made of resin, a conventional fuel tank pipe joint using a metal reinforcing collar is provided. In comparison, it is very advantageous in terms of cost.

また、本実施の形態の補強用リブ６０は、接続管部３０の中心軸を中心とした放射線上に延びる放射線部６１と、接続管部３０の内側断面と略同心状の環状部６１と、を有するように設けられているため、補強用リブ６０の配置バランスが良く補強強度の点で好適である。また、接続管部３０内の流路抵抗も低く、例えば燃料供給時の圧力損失が小さいという利点がある。更に、アンチサイフォン機能を奏することができるという利点もある。   Further, the reinforcing rib 60 of the present embodiment includes a radiation part 61 extending on the radiation around the central axis of the connection pipe part 30, an annular part 61 substantially concentric with the inner cross section of the connection pipe part 30, and Therefore, the arrangement balance of the reinforcing ribs 60 is good, which is preferable in terms of reinforcing strength. In addition, the flow path resistance in the connecting pipe part 30 is low, and there is an advantage that, for example, the pressure loss during fuel supply is small. Furthermore, there is an advantage that an anti-siphon function can be achieved.

また、本実施の形態の補強用リブ６０の環状部６１は、接続管部３０の中心軸に近い部分より接続管部３０の中心軸から遠い部分の方が高さが高くなっている。このことによっても、補強用リブ６０の配置バランスが良くなっていて、補強強度の点で好適となっている。   Further, the annular portion 61 of the reinforcing rib 60 of the present embodiment has a height higher in a portion farther from the central axis of the connecting tube portion 30 than in a portion near the central axis of the connecting tube portion 30. This also improves the arrangement balance of the reinforcing ribs 60, which is preferable in terms of reinforcing strength.

以上の通り、本実施の形態によれば、内側管部３２の内側に補強用リブ６０が渡されていることにより、金属製の補強用カラーを用いずとも、接続管部３０において十分な強度を実現することができる。特に、本実施の形態では、補強用リブ６０が樹脂製であるにも拘わらず接続管部３０において十分な強度を実現するため、金属製の補強用カラーを用いる従来の燃料タンク用管継手と比較してコストの面で非常に有利である。   As described above, according to the present embodiment, since the reinforcing rib 60 is passed inside the inner tube portion 32, sufficient strength is provided in the connecting tube portion 30 without using a metal reinforcing collar. Can be realized. In particular, in the present embodiment, in order to realize sufficient strength in the connecting pipe portion 30 even though the reinforcing rib 60 is made of resin, a conventional fuel tank pipe joint using a metal reinforcing collar is provided. In comparison, it is very advantageous in terms of cost.

また、本実施の形態によれば、接続管部３０が、フランジ部２０と一体の外側管部３１と、外側管部３１に対して嵌合される内側管部３２と、を有していて、燃料タンクに対してフランジ部２０と一体の外側管部３１を取り付ける際に内側管部３２が直接には関与しない。このため、燃料タンクに燃料タンク用管継手１０を取り付ける際に、部品点数が多く高価になりがちな内側管部３２を損傷してしまうというおそれが顕著に軽減される。   Further, according to the present embodiment, the connecting pipe part 30 has the outer pipe part 31 integral with the flange part 20 and the inner pipe part 32 fitted to the outer pipe part 31. The inner pipe portion 32 is not directly involved when the outer pipe portion 31 integrated with the flange portion 20 is attached to the fuel tank. For this reason, when attaching the fuel tank pipe joint 10 to the fuel tank, the risk of damaging the inner pipe portion 32, which tends to be expensive due to a large number of parts, is significantly reduced.

以上の実施の形態では、補強用リブ６０が、接続管部３０の中心軸を中心とした放射線上に延びる放射線部６１と、接続管部３０の内側断面と略同心状の環状部６１と、を有するように設けられていたが、少なくとも本願出願の時点においては、そのような態様に限定されない。例えば図４に示すように、補強用リブ６０’が接続管部３０の中心軸を中心とした放射線上に延びる放射線部６１’のみからなる燃料タンク用管継手１０’も、本発明の範囲に含まれる。但し、図４に示す補強用リブ６０’は、図３に示す補強用リブ６０と比較すると、流路抵抗が大きいという点で劣る。   In the above embodiment, the reinforcing rib 60 has a radiation part 61 extending on the radiation around the central axis of the connecting pipe part 30, an annular part 61 substantially concentric with the inner cross section of the connecting pipe part 30, and However, the present invention is not limited to such an embodiment at least at the time of filing this application. For example, as shown in FIG. 4, a fuel tank pipe joint 10 ′ in which the reinforcing rib 60 ′ includes only the radiation part 61 ′ extending on the radiation around the central axis of the connection pipe part 30 is also within the scope of the present invention. included. However, the reinforcing rib 60 'shown in FIG. 4 is inferior in that the flow path resistance is larger than the reinforcing rib 60 shown in FIG.
