Description

本発明は、複数のパイプを保持するパイプの保持構造に関する。   The present invention relates to a pipe holding structure for holding a plurality of pipes.

従来、車両の床下に敷設されるフューエルパイプやブレーキパイプ等の径の異なるパイプの車両の床下への取付けは、図６に示すように、パイプ１２１，１２２，１２３の周りを被覆部材１１０で覆い、さらに外側からブラケット１０１で保持され、ブラケット１０１が車両の床下に図示しないボルトにより取付けられる。ここでは、１本の細径のパイプ１２２と、パイプ１２２より太く、同じ直径を有する２本のパイプ１２１，１２３とを保持するパイプの保持構造である。   Conventionally, pipes having different diameters such as fuel pipes and brake pipes laid under the floor of the vehicle are mounted under the floor of the vehicle by covering the pipes 121, 122, and 123 with a covering member 110 as shown in FIG. Further, the bracket 101 is held from the outside, and the bracket 101 is attached to the under floor of the vehicle with a bolt (not shown). Here, it is a pipe holding structure that holds one small-diameter pipe 122 and two pipes 121 and 123 that are thicker than the pipe 122 and have the same diameter.

ブラケット１０１は被覆部材１１０の上側を挟み付ける上側締め付け部材１０２と、下側を挟み付ける下側締め付け部材１０３とからなる。被覆部材１１０は、例えば、ＥＰＤＭなどのゴムや樹脂などの弾性体からなる。
図７に示すように、上側締め付け部材１０２と下側締め付け部材１０３とで被覆部材１１０を締め付ける方向におけるパイプ１２１の外側と上側締め付け部材１０２または下側締め付け部材１０３との間の被覆部材１１０の大きさ、パイプ１２２の外側と上側締め付け部材１０２または下側締め付け部材１０３との間の被覆部材１１０の大きさ、パイプ１２３の外側と上側締め付け部材１０２または下側締め付け部材１０３との間の被覆部材１１０の大きさは異なる。
そのため、パイプ１２１，１２２，１２３を被覆部材１１０で覆い、被覆部材１１０を上側締め付け部材１０２と下側締め付け部材１０３とで挟み付けたときに、各パイプ１２１，１２２，１２３にかかる力が異なる。 The bracket 101 includes an upper fastening member 102 that sandwiches the upper side of the covering member 110 and a lower fastening member 103 that sandwiches the lower side. The covering member 110 is made of an elastic body such as rubber or resin such as EPDM, for example.
As shown in FIG. 7, the size of the covering member 110 between the outside of the pipe 121 and the upper fastening member 102 or the lower fastening member 103 in the direction in which the covering member 110 is fastened by the upper fastening member 102 and the lower fastening member 103. The size of the covering member 110 between the outside of the pipe 122 and the upper fastening member 102 or the lower fastening member 103, and the covering member 110 between the outside of the pipe 123 and the upper fastening member 102 or the lower fastening member 103 The size of is different.
Therefore, when the pipes 121, 122, 123 are covered with the covering member 110 and the covering member 110 is sandwiched between the upper fastening member 102 and the lower fastening member 103, the forces applied to the pipes 121, 122, 123 are different.

具体的には、図８に示すように、従来のパイプの保持構造は、直径Ｄ51が３０ｍｍのパイプ１３０と、直径ｄ51が２０ｍｍのパイプ１３１とをゴムなどの被覆部材１３２で覆い、被覆部材１３２の下側を下側締め付け部材１３３で締め付け、パイプ１３０，１３１を保持する構造である。下側締め付け部材１３３で被覆部材１３２を締め付ける前の下側締め付け部材１３３で被覆部材１３２を締め付ける方向におけるパイプ１３０，１３１の外側と下側締め付け部材１３３との間の被覆部材１３２の大きさ、即ち被覆部材１３２のパイプ１３０側の厚さＬ51は１５ｍｍであり、被覆部材１３２のパイプ１３１側の厚さｌ51は２０ｍｍである。下側締め付け部材１３３で被覆部材１３２を締め付けた後の被覆部材１３２が縮んでなる締め代ｈ51は、パイプ１３０側およびパイプ１３１側では５ｍｍである。 Specifically, as shown in FIG. 8, the conventional pipe holding structure is such that a pipe 130 having a diameter D 51 of 30 mm and a pipe 131 having a diameter d 51 of 20 mm are covered with a covering member 132 such as rubber. In this structure, the lower side of the member 132 is fastened by the lower fastening member 133 to hold the pipes 130 and 131. The size of the covering member 132 between the outside of the pipes 130 and 131 and the lower fastening member 133 in the direction in which the covering member 132 is fastened by the lower fastening member 133 before the covering member 132 is fastened by the lower fastening member 133, that is, The thickness L 51 on the pipe 130 side of the covering member 132 is 15 mm, and the thickness l 51 on the pipe 131 side of the covering member 132 is 20 mm. A fastening allowance h 51 formed by shrinking the covering member 132 after the covering member 132 is tightened by the lower fastening member 133 is 5 mm on the pipe 130 side and the pipe 131 side.

よって、被覆部材１３２のパイプ１３０の側における締め代の割合ρ51は１／３であり、被覆部材１３２のパイプ１３１の側における締め代の割合ρ52は１／４である。つまり、パイプ１３０を締め付ける力は、パイプ１３１を締め付ける力よりも大きい。
したがって、直径が細いパイプ１３１を締め付ける力は、パイプ１３１より太い直径を有する他のパイプ１３０を締め付ける力より小さく、それぞれのパイプ１３０，１３１に均一に力がかからないので、直径が細いパイプ１３１が回転したり、固定位置がずれたりしてしまうおそれがある。 Therefore, the tightening margin ratio ρ 51 on the pipe 130 side of the covering member 132 is ３, and the tightening margin ratio ρ 52 on the pipe 131 side of the covering member 132 is ¼. That is, the force for tightening the pipe 130 is larger than the force for tightening the pipe 131.
Therefore, the force for tightening the pipe 131 having a small diameter is smaller than the force for tightening the other pipe 130 having a diameter larger than that of the pipe 131, and the force is not applied uniformly to each of the pipes 130 and 131. Or the fixing position may be shifted.

自動車等の車体フロア下面に配設されるフューエルパイプやブレーキパイプ等の配管の前記車体フロア下面へ固定構造を工夫した技術として、下記特許文献１には配管固定構造に関する技術が開示されている。この技術では、部品点数を削減しつつパイプを車体フロア下面に極めて簡単に集束保持し固定できるものの、上記従来のパイプの保持構造と同様に、パイプ自体が回転したり、パイプの固定位置がずれたりしてしまうおそれがあった。   As a technique for devising a structure for fixing a pipe such as a fuel pipe or a brake pipe disposed on the lower surface of a vehicle body floor such as an automobile to the lower surface of the vehicle body floor, the following Patent Document 1 discloses a technique related to a pipe fixing structure. With this technology, while reducing the number of parts, it is very easy to focus and hold and fix the pipe to the underside of the vehicle floor. However, as with the conventional pipe holding structure described above, the pipe itself rotates or the pipe fixing position shifts. There was a risk of losing.

実公平５−１２１２９号公報No. 5-12129

本発明は、このような問題を解決するためになされたものであり、パイプが回転したり、該パイプを固定する位置がずれたりすることを防止するパイプの保持構造を提供するものである。   The present invention has been made to solve such a problem, and provides a pipe holding structure that prevents the pipe from rotating and the position where the pipe is fixed from being displaced.

上記課題を解決する第１の発明に係るパイプの保持構造は、径が異なる複数のパイプと、前記パイプを覆う弾性体の被覆部材と、前記被覆部材を挟んで締め付ける締め付け部材と、を備えるパイプの保持構造において、前記締め付け部材による締め付け方向の前記パイプの直径の方向における前記被覆部材の締め付け前の寸法に対する、前記直径の方向における前記被覆部材の締め代寸法の割合が、前記径が異なる複数のパイプの部分において略等しいことを特徴とする。   A pipe holding structure according to a first aspect of the present invention that solves the above problem includes a pipe comprising a plurality of pipes having different diameters, an elastic covering member that covers the pipe, and a tightening member that is clamped with the covering member interposed therebetween. In the holding structure, the ratio of the tightening allowance dimension of the covering member in the diameter direction to the dimension before the covering member is tightened in the diameter direction of the pipe in the tightening direction by the tightening member is a plurality of different diameters. It is characterized by being substantially equal in the pipe part.

上記課題を解決する第２の発明は、第１の発明に係るパイプの保持構造において、前記直径の方向における前記被覆部材の締め付け前の寸法と、前記直径の方向における前記被覆部材の締め代寸法とが、前記径が異なる複数のパイプの部分において略等しいことを特徴とする。   According to a second invention for solving the above-mentioned problem, in the pipe holding structure according to the first invention, a dimension before tightening of the covering member in the diameter direction and a tightening allowance dimension of the covering member in the diameter direction Are substantially equal in a plurality of pipe portions having different diameters.

第１の発明に係るパイプの保持構造によれば、径が異なる複数のパイプと、前記パイプを覆う弾性体の被覆部材と、前記被覆部材を挟んで締め付ける締め付け部材と、を備えるパイプの保持構造において、前記締め付け部材による締め付け方向の前記パイプの直径の方向における前記被覆部材の締め付け前の寸法に対する、前記直径の方向における前記被覆部材の締め代寸法の割合が、前記径が異なる複数のパイプの部分において略等しいことにより、同一の力で各パイプが保持されることになり、各パイプの回転や各パイプの固定位置のずれが抑止され、パイプ自体に余計な力が係ることを防ぐので、各パイプの品質の低下を抑止することができる。   According to the pipe holding structure according to the first aspect of the present invention, a pipe holding structure comprising a plurality of pipes having different diameters, an elastic covering member that covers the pipe, and a clamping member that is clamped with the covering member interposed therebetween. The ratio of the tightening allowance dimension of the covering member in the diameter direction to the dimension before the covering member is tightened in the diameter direction of the pipe in the tightening direction by the tightening member is a plurality of pipes having different diameters. By being substantially equal in the part, each pipe is held with the same force, and the rotation of each pipe and the displacement of the fixing position of each pipe are suppressed, so that unnecessary force is applied to the pipe itself, The deterioration of the quality of each pipe can be suppressed.

第２の発明に係るパイプ保持構造によれば、第１の発明において、前記直径の方向における前記被覆部材の締め付け前の寸法と、前記直径の方向における前記被覆部材の締め代寸法とが、前記径が異なる複数のパイプの部分において略等しいことにより、被覆部材と締め付け部材は各パイプの外縁に沿う形状となり一層パイプが安定して保持される。   According to the pipe holding structure according to the second invention, in the first invention, the dimension before tightening of the covering member in the diameter direction and the tightening allowance dimension of the covering member in the diameter direction are By being substantially equal in the portions of the plurality of pipes having different diameters, the covering member and the fastening member have a shape along the outer edge of each pipe, and the pipe is further stably held.

以下に、本発明の一実施形態に係るパイプの保持構造を説明する。   Below, the holding structure of the pipe which concerns on one Embodiment of this invention is demonstrated.

図１は、本発明の一実施形態に係るパイプの保持構造の斜視図であり、図２はその断面図である。   FIG. 1 is a perspective view of a pipe holding structure according to an embodiment of the present invention, and FIG. 2 is a sectional view thereof.

図１に示すように、このパイプの保持構造は、複数のパイプ１１，１２，１３を被覆部材、例えば弾性力を有するゴム１０などで覆い、さらにこの外側からブラケット１で保持している。複数のパイプ１１，１２，１３は横に並び、両側に配設され、太い直径を有する太径パイプ１１，１３と、真ん中に配設され、太径パイプ１１，１３より細い直径を有する細径パイプ１２とからなる。尚、太径パイプ１１の外径と太径パイプ１３の外径とは同じ大きさである。例えば、このようなパイプ１１，１２，１３としては、車両の床下に敷設されるフューエルパイプやブレーキパイプや冷却水が循環する冷却水用パイプなどが挙げられる。なお、冷却水用パイプなどでは、ゴム１０としてある程度耐熱性を有するＥＰＤＭなどを用いると好的である。   As shown in FIG. 1, in this pipe holding structure, a plurality of pipes 11, 12, and 13 are covered with a covering member, for example, rubber 10 having elasticity, and further held by a bracket 1 from the outside. The plurality of pipes 11, 12, 13 are arranged side by side, are arranged on both sides, and have a large diameter pipe 11, 13 having a large diameter, and a small diameter having a diameter smaller than that of the large diameter pipes 11, 13. It consists of a pipe 12. The outer diameter of the large-diameter pipe 11 and the outer diameter of the large-diameter pipe 13 are the same size. Examples of such pipes 11, 12, and 13 include a fuel pipe laid under the floor of a vehicle, a brake pipe, and a cooling water pipe through which cooling water circulates. In addition, in a pipe for cooling water or the like, it is preferable to use EPDM having a certain degree of heat resistance as the rubber 10.

ゴム１０はゴム１０の中央が中心に向って絞られた形状である。このゴム１０の中央には、太径パイプ１１の外径と同じ大きさの穴１０ａと、太径パイプ１３の外径と同じ大きさの穴１０ｃと、細径パイプ１２の外径と同じ大きさの穴１０ｂとが設けられる。
ゴム１０に設けられたこれらの穴１０ａ、１０ｂ、１０ｃは、ほぼ平面状に配設される。ゴム１０は、穴１０ａと穴１０ｂとの間、及び穴１０ｂと穴１０ｃとの間、並びに穴１０ｃとゴム１０の側面との間をそれぞれ切断した切込み１０ｄを有する。よって、この切込みによりゴム１０の一側側を広げることができるので、それぞれのパイプ１１，１２，１３を容易に所定の位置に配設することができる。 The rubber 10 has a shape in which the center of the rubber 10 is squeezed toward the center. At the center of the rubber 10, a hole 10 a having the same size as the outer diameter of the large diameter pipe 11, a hole 10 c having the same size as the outer diameter of the large diameter pipe 13, and the same size as the outer diameter of the small diameter pipe 12 A hole 10b is provided.
These holes 10a, 10b, and 10c provided in the rubber 10 are arranged in a substantially planar shape. The rubber 10 has cuts 10d that are cut between the hole 10a and the hole 10b, between the hole 10b and the hole 10c, and between the hole 10c and the side surface of the rubber 10. Therefore, since one side of the rubber 10 can be widened by this incision, the respective pipes 11, 12, 13 can be easily disposed at predetermined positions.

ブラケット１は、ゴム１０を上側から挟み付ける上側締め付け部材２と、ゴム１０を下側から保持する下側締め付け部材３とからなる。上側締め付け部材２は、ゴム１０の上面に接する形状である。
下側締め付け部材３は、ゴム１０を下側から把持する下側把持部４と、この下側把持部４の両側からそれぞれ外側へ延伸した第１下側フランジ５、第２下側フランジ６とからなる。つまり、下側締め付け部材３にゴム１０を収容することができる。なお、上側締め付け部材２の両端の近傍、第１下側フランジ５、第２下側フランジ６には、図示しないボルトが貫通するボルト孔２ａ，２ｂ，５ａ，６ａがそれぞれ設けられる。 The bracket 1 includes an upper fastening member 2 that sandwiches the rubber 10 from above, and a lower fastening member 3 that holds the rubber 10 from below. The upper fastening member 2 has a shape that is in contact with the upper surface of the rubber 10.
The lower clamping member 3 includes a lower grip 4 that grips the rubber 10 from below, a first lower flange 5 and a second lower flange 6 that extend outward from both sides of the lower grip 4. Consists of. That is, the rubber 10 can be accommodated in the lower fastening member 3. In addition, bolt holes 2a, 2b, 5a, and 6a through which bolts (not shown) pass are provided in the vicinity of both ends of the upper fastening member 2, the first lower flange 5, and the second lower flange 6, respectively.

次に、パイプをブラケット１での保持手順を説明する。
最初に、太径パイプ１１，１３及び細径パイプ１２におけるブラケット１の取付け位置に、ゴム１０を取り付ける。
続いて、ゴム１０の下側からブラケット１の下側締め付け部材３を取付ける。さらに、ゴム１０の上側からブラケット１の上側締め付け部材２を取付ける。このとき、ゴム１０を上側締め付け部材２及び下側締め付け部材３で挟み締め付けてゴム１０が縮んでなるゴム１０の締め代の大きさだけ、下側締め付け部材３の第１下側フランジ部５及び第２下側フランジ部６よりもゴム１０が上方にはみ出す。
続いて、上側締め付け部材２と下側締め付け部材３の第１下側フランジ部５及び第２下側フランジ部６とが接するまで、上側締め付け部材２と下側締め付け部材３とで図示しないボルトによってゴム１０を締め付ける。よって、ブラケット１により太径パイプ１１，１３及び細径パイプ１２が保持される。この締め付けにより、ゴム１０が上側締め付け部材２と下側締め付け部材３との間で縮み、この縮んだ大きさがゴム１０の締め代である。図２に示すように、太径パイプ１１，１３の外側と上側締め付け部材２または下側締め付け部材３との間のゴム１０の締め代と、細径パイプ１２の外側と上側締め付け部材２または下側締め付け部材３との間のゴム１０の締め代とは、ほぼ同一の大きさとなる。 Next, a procedure for holding the pipe with the bracket 1 will be described.
First, the rubber 10 is attached to the attachment position of the bracket 1 in the large diameter pipes 11 and 13 and the small diameter pipe 12.
Subsequently, the lower fastening member 3 of the bracket 1 is attached from the lower side of the rubber 10. Further, the upper fastening member 2 of the bracket 1 is attached from the upper side of the rubber 10. At this time, the first lower flange portion 5 of the lower tightening member 3 and the lower tightening member 3 are clamped by the size of the rubber 10 which is formed by sandwiching and tightening the rubber 10 between the upper tightening member 2 and the lower tightening member 3. The rubber 10 protrudes upward from the second lower flange portion 6.
Subsequently, until the upper tightening member 2 and the first lower flange portion 5 and the second lower flange portion 6 of the lower tightening member 3 are in contact with each other, the upper tightening member 2 and the lower tightening member 3 are connected by bolts (not shown). Tighten the rubber 10. Therefore, the large diameter pipes 11 and 13 and the small diameter pipe 12 are held by the bracket 1. By this tightening, the rubber 10 is contracted between the upper tightening member 2 and the lower tightening member 3, and the contracted size is the tightening allowance of the rubber 10. As shown in FIG. 2, the fastening allowance of rubber 10 between the outside of the large diameter pipes 11 and 13 and the upper fastening member 2 or the lower fastening member 3, and the outside of the small diameter pipe 12 and the upper fastening member 2 or below The fastening allowance of the rubber 10 between the side fastening members 3 is almost the same size.

よって、ゴム１０を上側締め付け部材２および下側締め付け部材３とにより締め付ける方向におけるゴム１０の締め代を、上側締め付け部材２および下側締め付け部材３とによりゴム１０を締め付ける前のパイプの外側と上側締め付け部材２または下側締め付け部材３との間のゴム１０の厚さで割ることにより算出される締め代の割合ρは、太径パイプ１１，１３の近傍と細径パイプ１２の近傍とで同一になる。
したがって、ゴム１０をブラケット１で保持したときに、パイプ１１，１２，１３のそれぞれを圧縮する力が同じであり、パイプ１１，１２，１３の固定位置がずれたり、回転したりすることが抑止され、パイプ１１，１２，１３に余計な力がかかることがないので、パイプ１１，１２，１３の品質の低下を抑止することができる。 Therefore, the fastening allowance of the rubber 10 in the direction in which the rubber 10 is fastened by the upper fastening member 2 and the lower fastening member 3, and the outer side and the upper side of the pipe before the rubber 10 is fastened by the upper fastening member 2 and the lower fastening member 3. The fastening ratio ρ calculated by dividing by the thickness of the rubber 10 between the fastening member 2 or the lower fastening member 3 is the same in the vicinity of the large diameter pipes 11 and 13 and in the vicinity of the small diameter pipe 12. become.
Therefore, when the rubber 10 is held by the bracket 1, the force for compressing each of the pipes 11, 12, 13 is the same, and the fixing positions of the pipes 11, 12, 13 are prevented from shifting or rotating. In addition, since no extra force is applied to the pipes 11, 12, and 13, it is possible to suppress deterioration of the quality of the pipes 11, 12, and 13.

より具体的に、各構成品の寸法を含めて、パイプの保持構造について、以下に説明する。なお、寸法は発明の理解を助けるために、あくまで例として挙げるものである。   More specifically, the pipe holding structure including the dimensions of each component will be described below. It should be noted that the dimensions are given as examples only to help the understanding of the invention.

以下に、本発明の第１の実施例に係るパイプの保持構造を説明する。
図３は、本発明の第１の実施例に係るパイプの保持構造の作用説明図である。 The pipe holding structure according to the first embodiment of the present invention will be described below.
FIG. 3 is an operation explanatory view of the pipe holding structure according to the first embodiment of the present invention.

細径パイプ２２の近傍におけるブラケット及びゴム２０を共に細径パイプ２２側に絞った形態である。
図３に示すように、直径Ｄ1が３０ｍｍである太径パイプ２１と、直径ｄ1が２０ｍｍである細径パイプ２２とを被覆部材であるゴム２０で覆い、ゴム２０の下側を下側締め付け部材２３で締め付け、パイプ２１及びパイプ２２を保持する構造である。
下側締め付け部材２３でゴム２０を締め付ける前の下側締め付け部材２３でゴム２０を締め付ける方向のパイプ２１，２２の直径の方向における直径延長線上のゴム２０の締め付け前の寸法、即ちゴム２０のパイプ２１側における厚さＬ21は１５ｍｍであり、ゴム２０のパイプ２２側における厚さｌ22も１５ｍｍである。
下側締め付け部材２３でゴム２０を締め付けた後のゴム２０のパイプ２１側における締め代ｈ21（前記締め付け前の寸法に対応する位置）は５ｍｍであり、パイプ２２側における締め代ｈ22も５ｍｍである。
よって、パイプ２１側における締め代の締め付け前寸法に対する割合ρ21は１／３であり、パイプ２２側における締め代の割合ρ22も１／３である。
したがって、ゴム２０を下側締め付け部材で締め付けることにより、パイプ２１にかかる力とパイプ２２にかかる力とは同じであるので、パイプ２１の固定位置およびパイプ２２の固定位置がずれたり、パイプ２１及びパイプ２２が回転したりすることがない。また、ゴム２０と下側締め付け部材２３はパイプ２１，２２の外縁に沿う形状となり、一層パイプが安定して保持される。 The bracket and the rubber 20 in the vicinity of the small diameter pipe 22 are both narrowed to the small diameter pipe 22 side.
As shown in FIG. 3, a large-diameter pipe 21 having a diameter D 1 of 30 mm and a small-diameter pipe 22 having a diameter d 1 of 20 mm are covered with a rubber 20 as a covering member, and the lower side of the rubber 20 is a lower side. The pipe 21 and the pipe 22 are held by fastening with the fastening member 23.
Before tightening the rubber 20 with the lower tightening member 23, the dimension of the rubber 20 on the diameter extension line in the direction of the diameter of the pipes 21, 22 in the direction of tightening the rubber 20 with the lower tightening member 23, that is, the pipe of the rubber 20 the thickness L 21 at 21 side is 15 mm, the thickness l 22 in the pipe 22 side of the rubber 20 is also 15 mm.
After tightening the rubber 20 with the lower tightening member 23, the tightening allowance h 21 on the pipe 21 side of the rubber 20 (position corresponding to the dimension before the tightening) is 5 mm, and the tightening allowance h 22 on the pipe 22 side is also 5 mm. It is.
Therefore, the ratio ρ 21 of the tightening allowance on the pipe 21 side to the dimension before tightening is 1/3, and the ratio ρ 22 of the tightening allowance on the pipe 22 side is also 1/3.
Therefore, when the rubber 20 is tightened with the lower tightening member, the force applied to the pipe 21 and the force applied to the pipe 22 are the same, and therefore, the fixing position of the pipe 21 and the fixing position of the pipe 22 are shifted. The pipe 22 does not rotate. Further, the rubber 20 and the lower fastening member 23 are shaped along the outer edges of the pipes 21 and 22, and the pipe is further stably held.

以下に、本発明の第２の実施例に係るパイプの保持構造を説明する。

FIG. 4 is an operation explanatory view of the pipe holding structure according to the second embodiment of the present invention.

細径パイプ３２の近傍におけるゴム３０を厚くし、このゴム３０を平らな下側締め付け部材により締め付けた形態である。
図４に示すように、第２の実施例のパイプの保持構造は、上記実施例１に記載されたパイプの保持構造における保持する前のゴム２０の厚さおよびゴム２０の締め代を変えた形態である。なお、パイプ３１はパイプ２１と同じ大きさであり、パイプ３２はパイプ２２と同じ大きさである。
