Description

本発明は、チューブやパイプ等の被保持部材を保持するクランプに関する。   The present invention relates to a clamp for holding a member to be held such as a tube or a pipe.

従来、例えば、ウォッシャーチューブやワイヤハーネス等を保持して自動車のボデー側に固定するクランプとして、チューブやワイヤハーネス等を粘着テープで巻き付けるようにしたものがある（例えば、特許文献１，２参照。）。   Conventionally, for example, as a clamp that holds a washer tube, a wire harness, and the like and is fixed to the body side of an automobile, the tube, the wire harness, and the like are wound with an adhesive tape (see, for example, Patent Documents 1 and 2). ).

しかし、チューブ等を粘着テープで巻き付ける上記クランプでは煩雑なテープ巻き作業工数が多く、作業時間が長くかかるという問題があった。そこで、粘着テープを不要にして作業工数の減少を図れるクランプとして、チューブ等をそれぞれ別個独立に保持するチューブ保持部と、このチューブ保持部の一側端部にヒンジ機構を介して回転自在に取り付けられた押え蓋とからなり、チューブ保持部に挿入されたチューブ等を押え蓋で押え込むようにしたものがある（例えば、特許文献３，４参照。）。   However, the above-described clamp that winds a tube or the like with an adhesive tape has a problem that it takes a lot of troublesome tape winding work and takes a long time. Therefore, as a clamp that eliminates the need for adhesive tape and reduces the work man-hours, a tube holding part that holds tubes and the like separately and is attached to one end of this tube holding part via a hinge mechanism so as to be rotatable. There is a structure in which a tube or the like inserted into a tube holding portion is pressed with a presser lid (for example, see Patent Documents 3 and 4).

しかしながら、特許文献３，４に記載された上記クランプでは、チューブ保持部に挿入されたチューブ等に対する押え蓋による押え込み力が不足すると、チューブ等がチューブ保持部内で滑ってチューブ長手方向（軸方向）にずれたり、チューブ円周方向にずれたりする。   However, in the clamps described in Patent Documents 3 and 4, if the pressing force by the pressing lid on the tube or the like inserted into the tube holding part is insufficient, the tube or the like slides in the tube holding part and is in the tube longitudinal direction (axial direction). Or in the tube circumferential direction.

The locking means 6 is not limited to this, and is in a locked state in which the other circumferential ends 3b, 4b of the holding semi-cylindrical portions 3, 4 are held in a closed position and an unlocked state in which the closed position is released. Any other configuration may be used as long as it can be switched.

他方の保持半円筒部４には、図３、図６のように、本クランプ１全体を例えば車体パネル１２等の所定箇所に取り付けて保持するための取付部１３が設けられる。この取付部１３は、例えば、図３、図６に示すように、上記両爪受脚部９，１０の下端に一体に連設した取付板１４に、車体パネル１２等の所定箇所に設けたクランプ孔１５へ挿入係止する矢印形状の係止羽根部１６を一体に突設するとともに、係止羽根部１６の付け根部周囲より車体パネル１２等へ圧接するための圧接用皿部１７を一体に張り出し形成している。   As shown in FIGS. 3 and 6, the other holding semi-cylindrical portion 4 is provided with an attachment portion 13 for attaching and holding the entire clamp 1 to a predetermined location such as a vehicle body panel 12. For example, as shown in FIGS. 3 and 6, the mounting portion 13 is provided at a predetermined position such as the vehicle body panel 12 on a mounting plate 14 integrally connected to the lower ends of the both claw receiving leg portions 9 and 10. An arrow-shaped locking blade portion 16 that is inserted into and locked in the clamp hole 15 is integrally projected, and a pressure-contacting plate portion 17 that is pressed from the periphery of the base portion of the locking blade portion 16 to the vehicle body panel 12 and the like is integrated.

本発明は、このような構成のクランプ１において、両保持半円筒部３，４の各内周に、滑り止めリブ２０を設けて、該滑り止めリブ２０を被保持部材２の外周に対して圧接し、この圧接により滑り止めリブ２０と被保持部材２の外周との接触面間で大きい摩擦力を発生し、被保持部材２がその長手方向にずれたり、回転方向にずれたりするのを規制するようにしてある点に特徴を有するものである。   According to the present invention, in the clamp 1 having such a configuration, the anti-slip ribs 20 are provided on the inner peripheries of the both holding semi-cylindrical portions 3 and 4, and the anti-slip ribs 20 are disposed on the outer periphery of the held member 2. Due to this pressure contact, a large frictional force is generated between the contact surfaces of the anti-slip rib 20 and the outer periphery of the held member 2, and the held member 2 is displaced in the longitudinal direction or in the rotational direction. It is characterized in that it is regulated.

図７、図８は、滑り止めリブ２０の第１実施例を示している。この実施例では、滑り止めリブ２０は、各保持半円筒部３，４の内周に沿い且つ該保持半円筒部３，４の筒中心軸に対し交差する斜め形状の円弧状リブ２１を複数個、各保持半円筒部３，４の筒中心軸方向に所定間隔置きに並べて設けてなる。円弧状リブ２１は断面形状が三角形や半円形状等の断面山形に形成している。
このように両保持半円筒部３，４の各内周に円弧状リブ２１を設けておくと、両保持半円筒部３，４を閉じてチューブ等の被保持部材２を保持する状態下においては、円弧状リブ２１は、図８（ａ），（ｂ）に示すように、被保持部材２の外周に対して圧接ないし食い込み係合し、被保持部材２との接触面間で生じる大きい摩擦力で、被保持部材２がその長手方向にずれたり、回転方向にずれたりするのを確実に規制することができる。 7 and 8 show a first embodiment of the anti-slip rib 20. In this embodiment, the anti-slip rib 20 includes a plurality of oblique arc-shaped ribs 21 along the inner circumference of each holding semi-cylindrical part 3, 4 and intersecting the cylinder center axis of the holding semi-cylindrical part 3, 4. The holding semi-cylindrical portions 3 and 4 are arranged at predetermined intervals in the cylinder central axis direction. The arc-shaped rib 21 has a cross-sectional mountain shape such as a triangular shape or a semicircular shape.
When the arc-shaped ribs 21 are provided on the inner peripheries of the holding semi-cylindrical parts 3 and 4 in this way, the holding semi-cylindrical parts 3 and 4 are closed and the held member 2 such as a tube is held. As shown in FIGS. 8A and 8B, the arc-shaped rib 21 is large in pressure contact or bite engagement with the outer periphery of the held member 2 and is generated between the contact surfaces with the held member 2. With the frictional force, the held member 2 can be reliably restricted from shifting in the longitudinal direction or in the rotational direction.

図１０〜図１２は、滑り止めリブ２０の第２実施例を示している。この実施例では、滑り止めリブ２０は、各保持半円筒部３，４の内周に沿い且つ該保持半円筒部３，４の筒中心軸に対し交差する第１の円弧状リブ２２と、この円弧状リブ２２にクロスする第２の円弧状リブ２３とからなり、これら第１，２の円弧状リブ２２，２３の複数組が各保持半円筒部３，４の筒中心軸方向に所定間隔置きに並べて設けられてなる。この場合において、各保持半円筒部３，４の筒中心軸に対し交差する第１の円弧状リブ２２には、各保持半円筒部３，４の筒中心軸に対し交差する斜め形状のものに限られず、各保持半円筒部３，４の筒中心軸に対し直角に交差するものをも含むものである。なお、第１，２の円弧状リブ２２，２３は、第１実施例の円弧状リブ２１と同様に、断面形状が三角形や半円形状等の断面山形に形成している。   10 to 12 show a second embodiment of the anti-slip rib 20. In this embodiment, the anti-slip rib 20 includes a first arc-shaped rib 22 that extends along the inner circumference of each holding semi-cylindrical part 3, 4 and intersects the cylinder center axis of the holding semi-cylindrical part 3, 4; A second arc-shaped rib 23 crossing the arc-shaped rib 22 is formed, and a plurality of sets of the first and second arc-shaped ribs 22 and 23 are predetermined in the cylinder central axis direction of the holding semi-cylindrical portions 3 and 4. It is arranged side by side at intervals. In this case, the first arc-shaped rib 22 that intersects the cylinder center axis of each holding semi-cylindrical portion 3, 4 has an oblique shape that intersects the cylinder center axis of each holding semi-cylindrical portion 3, 4. It is not restricted to this, The thing which cross | intersects perpendicularly with respect to the cylinder central axis of each holding | maintenance semi-cylindrical parts 3 and 4 is also included. The first and second arc-shaped ribs 22 and 23 are formed in a cross-sectional mountain shape such as a triangular shape or a semicircular shape in a cross-sectional shape, similar to the arc-shaped rib 21 of the first embodiment.

このように両保持半円筒部３，４の各内周に第１，２の円弧状リブ２２，２３を設けておいても、両保持半円筒部３，４を閉じてチューブ等の被保持部材２を保持する状態下においては、第１，２の円弧状リブ２２，２３は、図１１（ａ），（ｂ）、図１２（ａ），（ｂ）に示すように、第１実施例の円弧状リブ２１の場合とほぼ同様に、被保持部材２の外周に対して圧接ないし食い込み係合する。図１１（ａ），（ｂ）は第１，２の円弧状リブ２２，２３のクロス部分で切った断面図を示し、図１２（ａ），（ｂ）は第１，２の円弧状リブ２２，２３のクロスしていない部分で切った断面図を示す。したがって、被保持部材２は、第１，２の円弧状リブ２２，２３との接触面間で生じる大きい摩擦力で、その長手方向にずれたり、回転方向にずれたりするのを確実に規制することができる。   Thus, even if the first and second arc-shaped ribs 22 and 23 are provided on the inner peripheries of the holding semi-cylindrical portions 3 and 4, both the holding semi-cylindrical portions 3 and 4 are closed to hold the tube or the like. In the state where the member 2 is held, the first and second arc-shaped ribs 22 and 23 are formed in the first embodiment as shown in FIGS. 11 (a), 11 (b), 12 (a) and 12 (b). In substantially the same manner as in the case of the arcuate rib 21 in the example, the outer periphery of the held member 2 is pressed or bite engaged. FIGS. 11A and 11B are cross-sectional views taken along the cross portions of the first and second arc-shaped ribs 22 and 23, and FIGS. 12A and 12B are first and second arc-shaped ribs. Sectional drawing cut | disconnected in the part which is not crossing 22 and 23 is shown. Therefore, the held member 2 reliably restricts displacement in the longitudinal direction or in the rotational direction by a large frictional force generated between the contact surfaces with the first and second arc-shaped ribs 22 and 23. be able to.

図１３〜図１５は、滑り止めリブ２０の第３実施例を示している。この実施例では、滑り止めリブ２０は、各保持半円筒部３，４の内周に沿い且つ該保持半円筒部３，４の筒中心軸に対し交差する斜め形状の円弧状リブ２４を各保持半円筒部３，４の筒中心軸方向にジグザグ状に設けてなる。なお、この場合における円弧状リブ２４も、第１実施例の円弧状リブ２１と同様に、断面形状が三角形や半円形状等の断面山形に形成している。
このように両保持半円筒部３，４の各内周に円弧状リブ２４をジグザグ状に設けておいても、両保持半円筒部３，４を閉じてチューブ等の被保持部材２を保持する状態下においては、円弧状リブ２４は、図１４（ａ），（ｂ）、図１５（ａ），（ｂ）に示すように、これ又、第１実施例の円弧状リブ２１の場合とほぼ同様に、被保持部材２の外周に対して圧接ないし食い込み係合する。図１４（ａ），（ｂ）はジグザグ状の円弧状リブ２４のピッチの密な部分で切った断面図を示し、図１５（ａ），（ｂ）はジグザグ状の円弧状リブ２４のピッチの粗い部分で切った断面図を示す。したがって、ジグザグ状の円弧状リブ２４と被保持部材２との接触面間で生じる大きい摩擦力で、被保持部材２がその長手方向にずれたり、回転方向にずれたりするのを確実に規制することができる。 13 to 15 show a third embodiment of the anti-slip rib 20. In this embodiment, the anti-slip rib 20 is formed by forming an oblique arc-shaped rib 24 along the inner circumference of each holding semi-cylindrical portion 3, 4 and intersecting the cylinder center axis of the holding semi-cylindrical portion 3, 4. The holding semi-cylindrical portions 3 and 4 are provided in a zigzag shape in the cylinder central axis direction. Note that the arc-shaped rib 24 in this case is also formed in a cross-sectional mountain shape such as a triangle or a semicircular shape in the same manner as the arc-shaped rib 21 of the first embodiment.
Thus, even if the arc-shaped ribs 24 are provided in a zigzag shape on the inner peripheries of the holding semi-cylindrical portions 3 and 4, both the holding semi-cylindrical portions 3 and 4 are closed to hold the held member 2 such as a tube. Under the condition, the arc-shaped rib 24 is also the case of the arc-shaped rib 21 of the first embodiment as shown in FIGS. 14 (a), 14 (b), 15 (a), 15 (b). In substantially the same manner as above, the outer periphery of the held member 2 is pressed or bite engaged. 14A and 14B are cross-sectional views taken along a dense portion of the zigzag arcuate rib 24, and FIGS. 15A and 15B are pitches of the zigzag arcuate rib 24.

The third arc-shaped ribs 25 are obliquely arranged along the inner circumference of the other holding semi-cylindrical portion 4 and with respect to the cylinder central axis of the holding semi-cylindrical portion 4. A plurality of slanted fourth arc-shaped ribs 26 intersecting in the opposite direction to each other are arranged at predetermined intervals in the cylinder central axis direction. In this case, the third and fourth arc-shaped ribs 25 and 26 are also formed in a cross-sectional mountain shape such as a triangle or a semicircular shape in the same manner as the arc-shaped rib 21 of the first embodiment.

このように一方の保持半円筒部３の内周の第３の円弧状リブ２５と他方の保持半円筒部４の内周の第４の円弧状リブ２６とを互いに反対方向に斜め形状に設けておいても、両保持半円筒部３，４を閉じてチューブ等の被保持部材２を保持する状態下においては、第３，４の円弧状リブ２５，２６は、図１７（ａ），（ｂ）、図１８（ａ），（ｂ）に示すように、これ又、第１実施例の円弧状リブ２１の場合とほぼ同様に、被保持部材２の外周に対して圧接ないし食い込み係合し、被保持部材２との接触面間で生じる大きい摩擦力で、被保持部材２がその長手方向にずれたり、回転方向にずれたりするのを確実に規制することができる。   In this way, the third arc-shaped rib 25 on the inner periphery of one holding semi-cylindrical portion 3 and the fourth arc-shaped rib 26 on the inner periphery of the other holding semi-cylindrical portion 4 are provided obliquely in opposite directions. However, in a state where both the holding semi-cylindrical portions 3 and 4 are closed and the held member 2 such as a tube is held, the third and fourth arc-shaped ribs 25 and 26 are formed as shown in FIG. (B), as shown in FIGS. 18 (a) and 18 (b), as in the case of the arc-shaped rib 21 of the first embodiment, it is pressed against the outer periphery of the held member 2 or is engaged with the bite. In addition, it is possible to reliably regulate the displacement of the held member 2 in the longitudinal direction or the rotational direction by a large frictional force generated between the contact surfaces with the held member 2.
