Description
本発明は、水道管やガス管等の配管作業に適したパイプレンチに関するものである。
The present invention relates to a pipe wrench suitable for piping work such as a water pipe and a gas pipe.
水道管やガス管等を接続する場合には、図１に示すようにエルボ１やニップル２等の継手が用いられる。このような場合に、ニップルのねじ部を疵付けないように締め付けるためには、図１に示されるように幅の狭い部分に２本のパイプレンチを差し込んで互いに逆方向に回転させる作業が必要となる。
When connecting a water pipe or a gas pipe, a joint such as an elbow 1 or a nipple 2 is used as shown in FIG. In such a case, in order to tighten the screw portion of the nipple so as not to be damaged, it is necessary to insert two pipe wrenches into the narrow portion and rotate them in the opposite directions as shown in FIG. It becomes.
このため本出願人は、特許文献１に示される薄型のコーナーレンチを開発した。しかしこのコーナーレンチは図２に示すように、上顎５を移動可能に支持するフレーム３が本体４の長手方向に対して直角方向に大きく突出しているため、壁や別の配管に対して平行に配管を設置する場合には、フレーム３がまわりの障害物に当たり、締付作業が行えない場合があった。
Therefore, the present applicant has developed a thin corner wrench shown in Patent Document 1. However, in this corner wrench, as shown in FIG. 2, the frame 3 that supports the upper jaw 5 so as to be movable protrudes in a direction perpendicular to the longitudinal direction of the main body 4, so that it is parallel to the wall or another pipe. When installing piping, the frame 3 hits obstacles around it, and tightening work may not be possible.
このような場合には、特許文献２に示されるフレームの突出量が小さい一般的なパイプレンチを用いることが考えられる。しかし一般的なパイプレンチは図３に示すように、外径の大きい丸ナット６の内部に上顎５のラック部７を挿入し、丸ナット６を回転させて上顎５を本体４の長手方向に移動させる構造となっている。このため、パイプレンチの幅を丸ナット６の直径より薄くすることはできず、幅の狭い部分で２つのパイプレンチを使用すると、互いが干渉することがあった。
In such a case, it is conceivable to use a general pipe wrench with a small amount of projection of the frame shown in Patent Document 2. However, as shown in FIG. 3, a general pipe wrench inserts the rack portion 7 of the upper jaw 5 into the round nut 6 having a large outer diameter, and rotates the round nut 6 so that the upper jaw 5 extends in the longitudinal direction of the main body 4. It has a structure to move. For this reason, the width | variety of the pipe wrench cannot be made thinner than the diameter of the round nut 6, and when two pipe wrench was used in the narrow part, it might interfere with each other.
従って本発明の目的は上記した従来の問題点を解決し、狭い間隔で２本のパイプレンチを使用する必要がある場合にも相互の干渉を避けることができ、コーナーレンチ形状のパイプレンチを使用できない場所でも使用することができる新規なパイプレンチを提供することである。
Therefore, the object of the present invention is to solve the above-mentioned conventional problems, and even when it is necessary to use two pipe wrench at a narrow interval, mutual interference can be avoided, and a corner wrench-shaped pipe wrench is used. It is to provide a new pipe wrench that can be used even in places where it cannot.
上記の課題を解決するためになされた本発明のパイプレンチは、先端に植歯を備えた細長い本体と、本体の先端部側方にリベットにより軸支されたフレームと、このフレームを貫通する上顎と、この上顎を本体の長手方向に移動させるウォームとからなり、このウォームを本体と上顎との間の位置でフレームに支持させたことを特徴とするものである。
The pipe wrench of the present invention, which has been made to solve the above-mentioned problems, includes an elongated body having a tooth implant at the tip, a frame pivotally supported by a rivet on the side of the tip of the body, and an upper jaw passing through the frame And a worm for moving the upper jaw in the longitudinal direction of the main body, and the worm is supported by the frame at a position between the main body and the upper jaw.
好ましい実施形態においては、フレームが鋼板をＵ字状に折り曲げたものであり、その窓穴に形成された角部と上顎とによってウォームを支持させた構造とすることができる。また、ウォームがその両端部に突起を備え、これらの突起をＵ字状に折り曲げた鋼板間に挿入した構造とすることができる。さらに、フレームの前記リベットとは反対側の端部を斜めに突出させ、本体に形成した傾斜面と当接させた構造とすることができる。
In a preferred embodiment, the frame is formed by bending a steel plate into a U shape, and the worm can be supported by the corner portion and the upper jaw formed in the window hole. Further, the worm can have a structure in which protrusions are provided at both ends, and these protrusions are inserted between U-shaped steel plates. Further, the end of the frame opposite to the rivet can be protruded obliquely so as to be in contact with an inclined surface formed on the main body.
本発明のパイプレンチは、細長い本体と上顎との間の位置にウォームを配置し、このウォームを上顎の本体側の側面に形成されたラックと噛みあわせ、ウォームを回転させることによって上顎を本体の長手方向に移動させる構造とした。このため従来のような外径の大きい丸ナットを無くすことができ、パイプレンチの横幅を薄くすることができた。従って、狭い間隔で２本のパイプレンチを使用する必要がある場合にも相互の干渉を避けることができる。
In the pipe wrench of the present invention, a worm is disposed at a position between the elongated main body and the upper jaw, the worm is meshed with a rack formed on the side surface of the upper jaw on the main body side, and the worm is rotated to rotate the upper jaw to the main body. The structure is moved in the longitudinal direction. For this reason, the conventional round nut having a large outer diameter can be eliminated, and the horizontal width of the pipe wrench can be reduced. Therefore, even when it is necessary to use two pipe wrenches at a narrow interval, mutual interference can be avoided.
また本発明のパイプレンチは、本体の先端部側方に軸支されたフレームに本体の長手方向に移動する上顎を設けた構造であり、特許文献１に示すコーナーレンチ形状ではなく、一般的なパイプレンチと同様の基本形態を備えている。このため、壁や別の配管に対して平行に配管を設置する場合のように、コーナーレンチ形状のパイプレンチを使用できない場所でも使用することができる。
The pipe wrench of the present invention has a structure in which an upper jaw that moves in the longitudinal direction of the main body is provided on a frame that is pivotally supported on the side of the front end of the main body. It has the same basic form as a pipe wrench. For this reason, it can be used even in a place where a corner wrench-shaped pipe wrench cannot be used, as in the case of installing a pipe parallel to a wall or another pipe.
鋼板をＵ字状に折り曲げてフレームを構成し、その窓穴に形成された角部と上顎とによってウォームを支持させた構造とすれば、ウォームを支持させるための軸が不要となり、軸を支持する穴をフレームへ設けることも不要となる。このため部品点数の削減と、加工・組立の手数を省略することができる。
If the steel plate is bent in a U-shape to form a frame and the worm is supported by the corners and upper jaws formed in the window holes, the shaft for supporting the worm becomes unnecessary and the shaft is supported. It is not necessary to provide a hole to be formed in the frame. For this reason, it is possible to reduce the number of parts and the processing and assembly work.
また、ウォームの両端部に突起を形成し、これらの突起をＵ字状に折り曲げた鋼板間に挿入した構造とすれば、構造を複雑化することなく、ウォームのガタツキを防止することができる。
Further, if the protrusions are formed at both ends of the worm and the protrusions are inserted between U-shaped steel plates, the worm can be prevented from rattling without complicating the structure.
さらにフレームを本体に枢着するリベットとは反対側のフレーム端部を斜めに突出させ、本体に形成した傾斜面と当接させた構造とすれば、パイプや継手の締付時のフレームの回転力をフレーム端部の回転方向に対してより直角に近い面で受けることができる。このためフレームの加工誤差等があっても、締付け時のフレームの傾きをほぼ一定に維持することができる。
Furthermore, if the frame end opposite to the rivet that pivots the frame is protruded diagonally and is in contact with the inclined surface formed on the body, the frame rotates when tightening pipes and joints. The force can be received on a plane closer to the right angle with respect to the direction of rotation of the frame end. For this reason, even if there is a processing error of the frame, the inclination of the frame at the time of tightening can be maintained almost constant.
図４～図１１を参照しつつ、本発明の実施形態を説明する。
図４は実施形態のパイプレンチの正面図である。図中、１０は細長いハンドル部１１を備えた本体であり、その先端には植歯１２が固定されている。植歯１２はその歯面１３が本体１０の長手方向に対してほぼ直角となるように取付けられている。 An embodiment of the present invention will be described with reference to FIGS.
FIG. 4 is a front view of the pipe wrench of the embodiment. In the figure,reference numeral 10 denotes a main body provided with an elongated handle portion 11, and a tooth implant 12 is fixed to the tip thereof. The tooth implant 12 is attached so that its tooth surface 13 is substantially perpendicular to the longitudinal direction of the main body 10.
図４は実施形態のパイプレンチの正面図である。図中、１０は細長いハンドル部１１を備えた本体であり、その先端には植歯１２が固定されている。植歯１２はその歯面１３が本体１０の長手方向に対してほぼ直角となるように取付けられている。 An embodiment of the present invention will be described with reference to FIGS.
FIG. 4 is a front view of the pipe wrench of the embodiment. In the figure,
本体１０は図４、図７に示すように先端部の植歯１２よりもやや後方位置に貫通孔１４を備え、この貫通孔１４を貫通するリベット１５によって、本体１０の先端部側方にフレーム１６が軸支されている。フレーム１６は図８、図９に示すように鋼板をＵ字状に折り曲げたものであり、その先端側が本体１０に軸支されている。
As shown in FIGS. 4 and 7, the main body 10 includes a through hole 14 at a position slightly rearward of the tooth implant 12 at the tip, and a rivet 15 passing through the through hole 14 causes a frame to be formed on the side of the tip of the main body 10. 16 is pivotally supported. As shown in FIGS. 8 and 9, the frame 16 is formed by bending a steel plate into a U shape, and the front end side thereof is pivotally supported by the main body 10.
フレーム１６には窓穴１７が形成されており、その内部にウォーム１８が支持されている。ウォーム１８は円柱部１９の外周面に螺旋羽根２０を突出させたものである。またこの円柱部１９の両端部には、小径円柱状の突起２１、２１が形成されている。図８に示すように、窓穴１７はウォーム１８の前後左右に円柱部１９を受ける角部２２を備えている。フレーム１６は鋼板をＵ字状に折り曲げたものであるから、角部２２は前後左右の４か所となり、ウォーム１８の円柱部１９が支持される。
A window hole 17 is formed in the frame 16, and a worm 18 is supported therein. The worm 18 has a spiral blade 20 protruding from the outer peripheral surface of the cylindrical portion 19. Further, small-diameter columnar projections 21 and 21 are formed at both ends of the columnar portion 19. As shown in FIG. 8, the window hole 17 includes corner portions 22 that receive the cylindrical portion 19 on the front, rear, left, and right sides of the worm 18. Since the frame 16 is formed by bending a steel plate into a U-shape, the corner portions 22 are at four locations, front, rear, left, and right, and the column portion 19 of the worm 18 is supported.
また、ウォーム１８の両端部の小径円柱状の突起２１、２１が、図１０のＢ矢視図に示すようにＵ字状の折り曲げ部に挟み込まれることにより、矢印方向の移動が防止され、ウォーム１８のガタツキが防止される。
Further, the small-diameter columnar projections 21 and 21 at both ends of the worm 18 are sandwiched between U-shaped bent portions as shown in FIG. 18 rattles are prevented.
図４、図６に示すように、上顎２３のラック部２４がフレーム１６の折り曲げ部を貫通しており、ラック部２４とウォーム１８とが噛み合っている。すなわち、ウォーム１８は本体１０と上顎２３との間の位置でフレーム１６に備えられた円柱部１９を受ける角部２２と上顎２３のラック部２４に挟み込まれるように支持されており、ウォーム１８を回転させることによって、上顎２３を本体１０の長手方向に移動させることができる。
4 and 6, the rack portion 24 of the upper jaw 23 passes through the bent portion of the frame 16, and the rack portion 24 and the worm 18 are engaged with each other. That is, the worm 18 is supported so as to be sandwiched between the corner portion 22 that receives the cylindrical portion 19 provided in the frame 16 and the rack portion 24 of the upper jaw 23 at a position between the main body 10 and the upper jaw 23. By rotating, the upper jaw 23 can be moved in the longitudinal direction of the main body 10.
このような構造としたので、ウォーム１８を支持する軸は不要となり、軸を支持する穴をフレームへ設けることも不要となる。このため部品点数の削減を図ることができる。またウォーム１８をフレーム１６の窓穴１７内に落とし込むだけでよい。また従来のような外径の大きい丸ナットを用いないので、図５に示すようにパイプレンチの全幅を小さくすることができ、狭い間隔で２本のパイプレンチを使用する必要がある場合にも相互の干渉を避けることができる。
Because of such a structure, the shaft for supporting the worm 18 is not necessary, and it is not necessary to provide a hole for supporting the shaft in the frame. For this reason, the number of parts can be reduced. Further, it is only necessary to drop the worm 18 into the window hole 17 of the frame 16. In addition, since a conventional round nut with a large outer diameter is not used, the overall width of the pipe wrench can be reduced as shown in FIG. 5, and it is necessary to use two pipe wrench at a narrow interval. Mutual interference can be avoided.
図６に示すように、本体１０の中央部には２枚の突起２５が形成されており、上顎２３のラック部２４がこれらの突起２５，２５の間に挟み込まれるようになっている。そしてこの突起２５，２５の内側には、圧縮コイルばね２６が設けられており、上顎２３のラック部２４を常に本体１０から離れる方向に弾発している。このため従来と同様、上顎２３は植歯１２に接近する方向の力を受けている。
As shown in FIG. 6, two protrusions 25 are formed at the center of the main body 10, and the rack portion 24 of the upper jaw 23 is sandwiched between these protrusions 25 and 25. A compression coil spring 26 is provided inside the protrusions 25, 25, and the rack portion 24 of the upper jaw 23 is always repelled in a direction away from the main body 10. For this reason, as in the prior art, the upper jaw 23 receives a force in a direction approaching the tooth implant 12.
このように構成されたパイプレンチは、図１１に示すように上顎２３を開き、エルボやニップル等を植歯１２との間に噛み込ませて、本体１０のハンドル部１１に矢印方向の力を加えて回転させるものである。この構造は図３に示した一般的なパイプレンチに近いので、コーナーレンチ形状のパイプレンチが使用できない場合、例えば壁や別の配管に対して平行に配管を設置するような場合でも使用することができる。
The pipe wrench constructed in this manner opens the upper jaw 23 as shown in FIG. 11 and bites an elbow, nipple, or the like between the tooth implant 12 and applies a force in the direction of the arrow to the handle portion 11 of the main body 10. In addition, it is rotated. Since this structure is close to the general pipe wrench shown in Fig. 3, use it even when a corner wrench-shaped pipe wrench cannot be used, for example, when installing a pipe parallel to a wall or another pipe. Can do.
図４において本体１０のハンドル部１１に矢印方向の力を加えて回転させる時、上顎２３と植歯１２の歯面１３の摩擦力により、フレーム１６はリベット１５を回転中心として斜めに突出させた端部２７が本体１０の傾斜面２８に当接する。
In FIG. 4, when the handle portion 11 of the main body 10 is rotated by applying a force in the direction of the arrow, the frame 16 protrudes obliquely with the rivet 15 as the rotation center due to the frictional force between the upper jaw 23 and the tooth surface 13 of the tooth implant 12. The end portion 27 contacts the inclined surface 28 of the main body 10.
図３に示した従来構造では、本体４に矢印方向の力を加えた時、フレーム３が本体４と当接する面は垂直面８となっており、フレーム３にかかる回転力と垂直面８で受ける力のなす角度はθAとなる。θAが直角に近いほど当接する面の加工寸法のバラつきによりフレーム３の角度がバラつきやすい。このため図３の従来品はフレーム３の端部を大きく下方に延ばしてθAを大きくしている。
In the conventional structure shown in FIG. 3, when a force in the direction of the arrow is applied to the main body 4, the surface on which the frame 3 comes into contact with the main body 4 is the vertical surface 8. The angle formed by the force received is θA. As θA is closer to a right angle, the angle of the frame 3 tends to vary due to variations in the processing dimensions of the abutting surface. For this reason, in the conventional product of FIG. 3, the end of the frame 3 is greatly extended downward to increase θA.
これに対して本実施形態においては、図４に示すようにフレーム１６の端部２７を本体１０に形成した傾斜面２８と当接させ、フレーム１６にかかる回転力と当接面で受ける力のなす角度θBを大きくしている。これによりフレーム１６の端部を大きく下方に延ばすことなく、加工寸法のバラつきによるフレーム１６の角度のバラつきを最小限に抑制することができる利点がある。
On the other hand, in the present embodiment, as shown in FIG. 4, the end portion 27 of the frame 16 is brought into contact with the inclined surface 28 formed on the main body 10 so that the rotational force applied to the frame 16 and the force received by the contact surface are reduced. The formed angle θB is increased. Accordingly, there is an advantage that the variation in the angle of the frame 16 due to the variation in the processing dimension can be suppressed to the minimum without greatly extending the end portion of the frame 16 downward.
以上に説明したように、本発明のパイプレンチは薄型であり、狭い間隔で２本使用する必要がある場合にも相互の干渉を避けることができ、コーナーレンチ形状のパイプレンチを使用できない場所でも使用することができる利点がある。
As described above, the pipe wrench of the present invention is thin and can avoid mutual interference even when it is necessary to use two with a narrow interval, even in a place where a corner wrench shaped pipe wrench cannot be used. There are advantages that can be used.
