以下、添付図面を参照して、本発明の実施の形態について説明する。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

図１及び図２に示すように、本発明の実施の対象とする燃料配管保護部材１は、自動車のエンジンの燃料配管２に装着することにより燃料配管２を保護するものである。この燃料配管保護部材１は、図２に示すように、燃料配管２の周面を被う形状とされる。また、この燃料配管保護部材１は、高強度の材料を用いて、燃料配管２に作用する大荷重（最大２７ｋＮ）に耐えられる肉厚に形成される。 As shown in FIGS. 1 and 2, a fuel pipe protection member 1 to which the present invention is applied protects a fuel pipe 2 by attaching it to a fuel pipe 2 of an automobile engine. The fuel pipe protection member 1 is shaped to cover the peripheral surface of the fuel pipe 2, as shown in FIG. Moreover, the fuel pipe protection member 1 is made of a high-strength material and formed to have a thickness that can withstand a large load (up to 27 kN) acting on the fuel pipe 2 .

図１及び図２に示す燃料配管保護部材１においては、図２より明らかのように、断面形状がＵ字状に形成され、開口部３を利用して燃料配管２に対して装着できるようになっている。燃料配管保護部材１の前記断面の内面は、燃料配管２の外周面の形状に対応している。燃料配管保護部材１の前記断面の外面は、図２に示すＵ字状のほか、コ字状や図３に示す台形状とすることもできる。 As is clear from FIG. 2, the fuel pipe protection member 1 shown in FIGS. 1 and 2 has a U-shaped cross-section and can be attached to the fuel pipe 2 using the opening 3. It's becoming The inner surface of the cross section of the fuel pipe protection member 1 corresponds to the shape of the outer peripheral surface of the fuel pipe 2 . The outer surface of the cross section of the fuel pipe protection member 1 may be U-shaped as shown in FIG. 2, U-shaped, or trapezoidal as shown in FIG.

次に、前記高強度の材料としては、機械構造用炭素鋼、アルミ合金、チタン合金等の金属が挙げられる。これらの高強度の材料のいずれかを用いて、燃料配管保護部材１は、燃料配管２に作用する大荷重（最大２７ｋＮ）に耐えられる肉厚Ｔに形成される。具体的な肉厚値としては、２～５ｍｍとするのが好ましい。燃料配管保護部材１の、燃料配管２の軸線Ｘ方向の長さＬは任意であるが、背景技術の項で述べた前記従来の保護部材よりも短く形成するのが好ましい。具体的な長さＬは、例えば１０～３０ｍｍ程度とするのが好ましい。燃料配管保護部材１を前記のような寸法にすると、長さＬがはるかに短く肉厚Ｔが厚いことにより、燃料配管保護部材１の強度が相乗的に高まる。 Next, examples of the high-strength materials include metals such as carbon steel for machine structural use, aluminum alloys, and titanium alloys. Using any one of these high-strength materials, the fuel pipe protection member 1 is formed with a wall thickness T that can withstand a large load (up to 27 kN) acting on the fuel pipe 2 . A specific thickness value is preferably 2 to 5 mm. Although the length L of the fuel pipe protection member 1 in the direction of the axis X of the fuel pipe 2 is arbitrary, it is preferably formed shorter than the conventional protection member described in the background art section. A specific length L is preferably about 10 to 30 mm, for example. When the fuel pipe protection member 1 is dimensioned as described above, the strength of the fuel pipe protection member 1 is synergistically increased due to the much shorter length L and the thicker wall thickness T.

なお、前記の燃料配管保護部材１は、長さＬが短いので、燃料配管２の軸線Ｘ方向に沿って複数並べて配設することができる。燃料配管２に対する燃料配管保護部材１の固定は、後述する本発明の燃料配管保護部材用固定具６を用いて行うと好適である。この場合、燃料配管保護部材１と燃料配管保護部材用固定具６との組み合わせで燃料配管２の軸線Ｘ方向に沿って複数配設される。 Since the length L of the fuel pipe protection member 1 is short, a plurality of fuel pipe protection members 1 can be arranged along the axis X direction of the fuel pipe 2 . It is preferable to fix the fuel pipe protection member 1 to the fuel pipe 2 by using the fuel pipe protection member fixture 6 of the present invention , which will be described later. In this case, a plurality of fuel pipe protection members 1 and fuel pipe protection member fixtures 6 are arranged along the axis X direction of the fuel pipe 2 in combination.

前記の特徴を有する燃料配管保護部材１は、それ自体が比較的強固であるため、車両の衝突により燃料配管２がフレームとキャビンクロスの間に挟まれても、燃料配管保護部材１が燃料配管２を確実に保護する。よって、車両衝突時に燃料配管２の損壊が生ずることがなく、燃料漏れやそれに起因する火災発生等の心配がない。 Since the fuel pipe protection member 1 having the above characteristics is itself relatively strong, even if the fuel pipe 2 is caught between the frame and the cabin cloth due to a collision of the vehicle, the fuel pipe protection member 1 can To surely protect a fuel pipe 2. - 特許庁Therefore, the fuel pipe 2 will not be damaged when the vehicle collides, and there is no fear of fuel leakage or the resulting fire.

燃料配管保護部材１の長さＬは、前記長さの範囲の中でも特に２０ｍｍに形成すると好適である。強度の高さと燃料配管２の軸線Ｘ方向における保護範囲の広さとの双方において利点が得られるからである。 It is preferable that the length L of the fuel pipe protection member 1 is set to 20 mm in the above length range. This is because advantages can be obtained in both high strength and a wide protection range in the direction of the axis X of the fuel pipe 2 .

前記燃料配管保護部材１を燃料配管２に対して固定するために用いる本発明の燃料配管保護部材用固定具６は、図１、図４及び図５に示すように、燃料配管２に装着された燃料配管保護部材１を包み込んで互いに結合可能な、複数のカバー片６ａ、６ｂを備える。そして、該複数のカバー片６ａ、６ｂの少なくともいずれかに、燃料配管２上における燃料配管保護部材用固定具６の位置ずれを防止する位置固定手段７が配設される。 The fuel pipe protection member fixture 6 of the present invention used for fixing the fuel pipe protection member 1 to the fuel pipe 2 is attached to the fuel pipe 2 as shown in FIGS. It includes a plurality of cover pieces 6a, 6b that can wrap the fuel pipe protection member 1 and can be connected to each other. At least one of the plurality of cover pieces 6a and 6b is provided with a position fixing means 7 for preventing positional deviation of the fixing member 6 for the fuel pipe protection member on the fuel pipe 2. As shown in FIG.

前記複数のカバー片６ａ、６ｂは、一例として、第１カバー片６ａと第２カバー片６ｂとを備える。これらのカバー片６ａ、６ｂは、適宜の金属材料を用いて形成される。下側の第１カバー片６ａは平板状に形成され、上側の第２カバー片６ｂは燃料配管保護部材１の外周形状に対応する形状を有する。そして、図４に示すように、燃料配管２に装着された燃料配管保護部材１を包み込むようにして第１カバー片６ａと第２カバー片６ｂとを相互に結合させた状態において、第１カバー片６ａの内面６ｃが燃料配管保護部材１の開口部３の端面３ａ、３ｂに当接し、第２カバー片６ｂの内面６ｄが燃料配管保護部材１の外面に当接する。 For example, the plurality of cover pieces 6a and 6b include a first cover piece 6a and a second cover piece 6b. These cover pieces 6a and 6b are formed using an appropriate metal material. The lower first cover piece 6 a is formed in a flat plate shape, and the upper second cover piece 6 b has a shape corresponding to the outer peripheral shape of the fuel pipe protection member 1 . Then, as shown in FIG. 4, in a state in which the first cover piece 6a and the second cover piece 6b are joined together so as to wrap the fuel pipe protection member 1 attached to the fuel pipe 2, the first cover The inner surface 6c of the piece 6a contacts the end surfaces 3a and 3b of the opening 3 of the fuel pipe protection member 1, and the inner surface 6d of the second cover piece 6b contacts the outer surface of the fuel pipe protection member 1.

前記第１カバー片６ａと第２カバー片６ｂは、非結合状態において分離する態様であってもよいが、図１に示すように、可撓性連結部８を介して常時連結状態にある態様にすると好適である。可撓性連結部８とは逆側において、第２カバー片６ｂには係止部９ｂが形成され、第１カバー片６ａには、前記係止部９ｂと係合する係止受部９ａが形成される。係止部９ｂと係止受部９ａとの係合により、第１カバー片６ａと第２カバー片６ｂとの結合状態が維持される。なお、複数のカバー片６ａ、６ｂは、三つ以上のカバー片で構成してもよいことは勿論である。 The first cover piece 6a and the second cover piece 6b may be separated in a non-bonded state, but as shown in FIG. It is preferable to use On the side opposite to the flexible connecting portion 8, the second cover piece 6b is formed with an engaging portion 9b, and the first cover piece 6a is provided with an engaging portion 9a that engages with the engaging portion 9b. It is formed. The engagement between the locking portion 9b and the locking receiving portion 9a maintains the coupled state between the first cover piece 6a and the second cover piece 6b. It goes without saying that the plurality of cover pieces 6a and 6b may be composed of three or more cover pieces.

図１、図４及び図５に示す燃料配管保護部材用固定具６は、前記位置固定手段７として、第１カバー片６ａと第２カバー片６ｂとの相互結合状態において燃料配管２の外周面２ａを挟持する挟持部１０を備えている。すなわち、第１カバー片６ａの両端部に、燃料配管２の外周面２ａの一部に当接する第１当接片１０ａが形成され、第２カバー片６ｂの両端部に燃料配管２の外周面２ａの一部に当接する第２当接片１０ｂが形成されている。第２当接片１０ｂは燃料配管２の外周形状に適合する円弧状に形成されている。そして、第１カバー片６ａと第２カバー片６ｂの両端部のそれぞれにおいて、第１当接片１０ａと第２当接片１０ｂとの組み合わせによって前記挟持部１０が構成される。 1, 4 and 5, the fixing member 6 for the fuel pipe protection member shown in FIGS. A clamping portion 10 for clamping 2a is provided. That is, first contact pieces 10a are formed on both ends of the first cover piece 6a to contact a part of the outer peripheral surface 2a of the fuel pipe 2, and both ends of the second cover piece 6b are formed on the outer peripheral surface of the fuel pipe 2. A second abutment piece 10b is formed to abut on a portion of the 2a. The second contact piece 10b is formed in an arc shape that conforms to the outer peripheral shape of the fuel pipe 2. As shown in FIG. The clamping portion 10 is formed by combining the first contact piece 10a and the second contact piece 10b at both ends of the first cover piece 6a and the second cover piece 6b, respectively.

第１カバー片６ａと第２カバー片６ｂとを相互に結合させると、第１当接片１０ａと第２当接片１０ｂとが燃料配管２の外周面２ａを挟持する。これにより、燃料配管保護部材用固定具６と燃料配管保護部材１が燃料配管２の軸線Ｘ方向に位置ずれしたり、燃料配管２の周方向に回ったりすることが防止される。なお、図２に示すように、燃料配管２の表面に樹脂被覆１１が施されている場合には、この樹脂被覆１１に対して第１当接片１０ａと第２当接片１０ｂとが噛み込むように構成すると、位置固定作用が確実に奏されて一層好適である。 When the first cover piece 6a and the second cover piece 6b are joined together, the outer peripheral surface 2a of the fuel pipe 2 is sandwiched between the first contact piece 10a and the second contact piece 10b. This prevents the fuel pipe protection member fixture 6 and the fuel pipe protection member 1 from being displaced in the axial line X direction of the fuel pipe 2 or from rotating in the circumferential direction of the fuel pipe 2 . As shown in FIG. 2, when the surface of the fuel pipe 2 is covered with a resin coating 11, the first contact piece 10a and the second contact piece 10b engage with the resin coating 11. It is more preferable to make the structure so that the position is fixed reliably.

別の態様の位置固定手段７として、図６に示すように、前記挟持部１０に代えて、又は前記挟持部１０に加えて、前記燃料配管２に隣接する適宜の固定フレーム１２の取付孔１２ａに嵌合する脚部１３を備えるものを例示する。すなわち、複数のカバー片６ａ、６ｂの少なくともいずれかに前記脚部１３を設ける態様である。図６の例では、第１カバー片６ａの外面に前記脚部１３を設けてある。前記固定フレーム１２としては、自動車の車体内において燃料配管２に隣接して不動状態で位置する適宜の部材を活用することができる。 As another embodiment of the position fixing means 7, as shown in FIG. An example is provided with a leg portion 13 that fits into the. That is, in this mode, the leg portion 13 is provided on at least one of the plurality of cover pieces 6a and 6b. In the example of FIG. 6, the legs 13 are provided on the outer surface of the first cover piece 6a. As the fixed frame 12, an appropriate member that is positioned adjacent to the fuel pipe 2 in the body of the automobile in an immovable state can be used.

図６に示すように、第１カバー片６ａと第２カバー片６ｂとを結合させるとともに、燃料配管２に隣接する固定フレーム１２の取付孔１２ａに脚部１３を嵌合させることによって、燃料配管保護部材用固定具６と燃料配管保護部材１が燃料配管２の軸線Ｘ方向に位置ずれしたり、燃料配管２の周方向に回ったりすることが防止される。 As shown in FIG. 6, the first cover piece 6a and the second cover piece 6b are joined together, and the leg portion 13 is fitted into the mounting hole 12a of the fixed frame 12 adjacent to the fuel pipe 2, whereby the fuel pipe is The protective member fixture 6 and the fuel pipe protective member 1 are prevented from being displaced in the direction of the axis X of the fuel pipe 2 and from rotating in the circumferential direction of the fuel pipe 2 .
