Description

本発明は、ボルトを締め込む工具と組み合わせる締め込み補助工具の構造に関する。 The present invention relates to the structure of a tightening auxiliary tool to be combined with a tool for tightening bolts.

従来、軸本体の一端にボルトの頭部と嵌合する作業部を備え、軸本体の他端にハンドル部を備えている工具が知られている。工具は、作業部を深い穴の底又は周囲を構造物に囲まれた狭い箇所に入れ、ボルトの緩めや締め付けを行っていた（例えば、特許文献１を参照）。 Conventionally, there is known a tool having a working portion that fits with the head of a bolt at one end of the shaft body and a handle portion at the other end of the shaft body. The tool puts the working part in a narrow place surrounded by a structure at the bottom or the periphery of a deep hole to loosen or tighten bolts (see, for example, Patent Document 1).

特開平９−１５０３７３号公報Japanese Unexamined Patent Publication No. 9-150373

特許文献１に開示されている工具によれば、ボルトの頭部に対しボルトの軸方向からアクセスできる状況であればボルトの締め付けを行える。しかし、ボルトの軸方向に障害物が存在するような場合は、工具を使用することができない、という課題があった。また、ボルトの軸方向に障害物がある箇所においては、六角レンチ又はモンキースパナ等の締め込み工具を用いる場合がある。例えば、六角レンチを用いてボルトを締め込む際に、六角レンチの長さが短いため、ボルトの締め込みトルクが不足する場合がある。このとき、真っ直ぐに延びるパイプを締め込み補助工具として六角レンチの端部に嵌合させて、作業者がパイプに力を加えて、締め込みトルクを確保していた。しかし、真っ直ぐなパイプを使用した場合、周囲の障害物によりパイプを動かせる範囲が狭く、作業効率が低下してしまうという課題があった。 According to the tool disclosed in Patent Document 1, the bolt can be tightened as long as the head of the bolt can be accessed from the axial direction of the bolt. However, there is a problem that the tool cannot be used when there is an obstacle in the axial direction of the bolt. Further, in a place where there is an obstacle in the axial direction of the bolt, a tightening tool such as a hexagon wrench or a monkey spanner may be used. For example, when tightening a bolt with a hexagon wrench, the tightening torque of the bolt may be insufficient because the length of the hexagon wrench is short. At this time, the straight pipe was fitted to the end of the hexagon wrench as a tightening auxiliary tool, and the operator applied force to the pipe to secure the tightening torque. However, when a straight pipe is used, there is a problem that the range in which the pipe can be moved is narrow due to surrounding obstacles and the work efficiency is lowered.

本発明は上記課題を解決するものであって、周囲に障害物があってもボルトの締め込み作業の効率を確保できる締め込み補助工具を提供することを目的としている。 The present invention solves the above problems, and an object of the present invention is to provide a tightening auxiliary tool capable of ensuring the efficiency of bolt tightening work even if there are obstacles in the surroundings.

本発明に係る締め込み補助工具は、柱形状の基礎部と、前記基礎部の一方の端から前記基礎部の延びる第１方向に対し交差する第２方向に延びる第１端部と、前記第１方向及び前記第２方向に対し交差する第３方向に沿って延びる短尺部と、を備え、前記短尺部は、前記基礎部の他方の端に中央部が接合され、一方の端に第２端部と、他方の端に第３端部と、を備え、前記第１端部、前記第２端部、及び前記第３端部は、管状に形成されており端面から工具が挿入自在に形成されている。 The tightening auxiliary tool according to the present invention includes a pillar-shaped foundation portion, a first end portion extending from one end of the foundation portion in a second direction intersecting with the first direction in which the foundation portion extends, and the first end portion. A short portion extending along a third direction intersecting one direction and the second direction is provided, and the short portion has a central portion joined to the other end of the foundation portion and a second portion to one end. It is provided with an end portion and a third end portion at the other end, and the first end portion, the second end portion, and the third end portion are formed in a tubular shape so that a tool can be inserted from the end face. It is formed.

本発明に係る締め込み補助工具によれば、上記の構成により、周囲に障害物があっても、工具が差し込まれた第１端部、第２端部、又は第３端部の何れかの中心軸周りに、締め込み補助工具を回転させることにより、締め込み補助工具が延びる方向を変更しながらボルトの締め込みが行える。そのため、締め込み補助工具を動かすことにより得られるボルトの回転量を増加させることができ、ボルトの締め込み作業の効率が向上する。 According to the tightening auxiliary tool according to the present invention, according to the above configuration, even if there is an obstacle in the surroundings, any one of the first end portion, the second end portion, or the third end portion into which the tool is inserted. By rotating the tightening auxiliary tool around the central axis, the bolt can be tightened while changing the direction in which the tightening auxiliary tool extends. Therefore, the amount of rotation of the bolt obtained by moving the tightening auxiliary tool can be increased, and the efficiency of the bolt tightening work is improved.

以下、本発明の実施の形態を図面に基づいて説明する。なお、以下に説明する実施の形態によって本発明が限定されるものではない。各図は模式的に示すものであって、各部材の相対的な大きさや板厚等は図示する寸法に限定されるものではない。また、以下の図面では各構成部材の大きさの関係が実際のものとは異なる場合がある。また、図において各部分に付された符号について、添え字（ａ、ｂ等）を付していない場合は、添え字が付された符号を総称しているものとする。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below. Each figure is schematically shown, and the relative size, plate thickness, etc. of each member are not limited to the dimensions shown. Further, in the drawings below, the relationship between the sizes of the constituent members may differ from the actual one. In addition, when the subscripts (a, b, etc.) are not added to the codes attached to each part in the figure, the codes with the subscripts are generically referred to.

実施の形態１．
図１は、実施の形態１に係る締め込み補助工具１００の三面図である。図１（ａ）は、締め込み補助工具１００の上面図、図１（ｂ）は、締め込み補助工具１００の平面図、図１（ｃ）は、締め込み補助工具１００の底面図である。締め込み補助工具１００は、ボルト８１（図２参照）等の締結要素を締め込む又は緩める場合に用いるものである。例えば六角レンチ又はモンキースパナ等の工具を第１端部２０の端面２１から差し込み、締め込み補助工具１００の短尺部３０側の一部分を把持して力を加えることにより、作業者はボルト８１に締結又は緩めに十分なトルクを容易に加えることができる。 Embodiment 1.
FIG. 1 is a three-view view of the tightening auxiliary tool 100 according to the first embodiment. 1 (a) is a top view of the tightening auxiliary tool 100, FIG. 1 (b) is a plan view of the tightening auxiliary tool 100, and FIG. 1 (c) is a bottom view of the tightening auxiliary tool 100. The tightening auxiliary tool 100 is used when tightening or loosening a fastening element such as a bolt 81 (see FIG. 2). For example, a tool such as a hexagon wrench or a monkey spanner is inserted from the end surface 21 of the first end portion 20, and a part of the tightening auxiliary tool 100 on the short portion 30 side is grasped and a force is applied to the operator to fasten the bolt 81. Alternatively, sufficient torque can be easily applied for loosening.

締め込み補助工具１００は、柱形状の基礎部１０を備える。基礎部１０は、直線状に延びる柱形状であり、実施の形態１においては円柱形状、更に詳細には中空円筒形状となっている。当該基礎部１０が延びる方向を第１方向と呼ぶ。実施の形態１において、第１方向は、図１に示されているｘ方向と一致している。なお、図１（ｂ）において、ｘ方向に直交する上方向をｙ方向、ｘｙ平面に直交する方向をｚ方向としている。また、締め込み補助工具１００は、基礎部１０の一方の端１１、即ちｘ方向の端１１から基礎部１０が延びる第１方向に対し交差する第２方向に延びる第１端部２０を備える。第１端部２０は、管状に形成されており、工具が挿入自在に構成されている。実施の形態１においては、第１端部２０と基礎部１０とが成す角度θ１は、１６０°に設定されているが、この角度だけに限定されるものではない。また、実施の形態１において、基礎部１０の長さは、４２０ｍｍに設定されており、第１端部２０の長さは、９０ｍｍに設定されている。 The tightening auxiliary tool 100 includes a pillar-shaped base portion 10. The foundation portion 10 has a columnar shape extending in a straight line, and in the first embodiment, it has a cylindrical shape, and more specifically, a hollow cylindrical shape. The direction in which the foundation portion 10 extends is called the first direction. In Embodiment 1, the first direction coincides with the x direction shown in FIG. In FIG. 1B, the upward direction orthogonal to the x direction is the y direction, and the direction orthogonal to the xy plane is the z direction. Further, the tightening auxiliary tool 100 includes one end 11 of the foundation portion 10, that is, a first end portion 20 extending in the second direction intersecting the first direction in which the foundation portion 10 extends from the end 11 in the x direction. The first end portion 20 is formed in a tubular shape, and is configured so that a tool can be inserted freely. In the first embodiment, the angle θ1 formed by the first end portion 20 and the foundation portion 10 is set to 160 °, but the angle is not limited to this angle. Further, in the first embodiment, the length of the foundation portion 10 is set to 420 mm, and the length of the first end portion 20 is set to 90 mm.

また、基礎部１０の他方の端、即ちｘ方向逆側の端１２には、第１方向及び第２方向に交差する第３方向に延びる短尺部３０が接合されている。短尺部３０は、基礎部１０と比較して短く、実施の形態１においては短尺部３０の長さは、１１０ｍｍに設定されている。短尺部３０は、基礎部１０の他方の端１２に中央部が接合されている。実施の形態１においては、短尺部３０と基礎部１０とが成す角度θ２は、６０°に設定されているが、この角度だけに限定されるものではない。短尺部３０は、一方の端に第２端部３３、他方の端に第３端部３４、を備える。第２端部３３及び第３端部３４は、管状に形成されており端面３１及び端面３２から工具を挿入自在に形成されている。基礎部１０は、第１端部２０及び短尺部３０に対し長い。そのため、第１端部２０、第２端部３３、又は第３端部３４に六角レンチ８０が挿し込まれた状態において、締め込み補助工具１００は、六角レンチ８０から遠い部分に力を加えることができ、ボルトの締め込み又は緩め時に比較的大きな力を加えることが可能となる。 Further, a short portion 30 extending in the third direction intersecting the first direction and the second direction is joined to the other end of the foundation portion 10, that is, the end 12 on the opposite side in the x direction. The short portion 30 is shorter than the foundation portion 10, and in the first embodiment, the length of the short portion 30 is set to 110 mm. The short portion 30 has a central portion joined to the other end 12 of the foundation portion 10. In the first embodiment, the angle θ2 formed by the short portion 30 and the foundation portion 10 is set to 60 °, but the angle is not limited to this angle. The short portion 30 includes a second end portion 33 at one end and a third end portion 34 at the other end. The second end portion 33 and the third end portion 34 are formed in a tubular shape, and a tool can be freely inserted from the end face 31 and the end face 32. The foundation portion 10 is longer than the first end portion 20 and the short portion 30. Therefore, when the hexagon wrench 80 is inserted into the first end portion 20, the second end portion 33, or the third end portion 34, the tightening auxiliary tool 100 applies a force to a portion far from the hexagon wrench 80. It is possible to apply a relatively large force when tightening or loosening the bolt.

図１に示される様に、基礎部１０、第１端部２０、及び短尺部３０は、それぞれ中心軸が同一面上にあるように配置されている。即ち、基礎部１０、第１端部２０、及び短尺部３０の中心軸は、それぞれ図１に示される様にｘｙ平面上に配置されている。また、基礎部１０、第１端部２０、及び短尺部３０は、鋼製のパイプにより構成されている。つまり、締め込み補助工具１００は、鋼製のパイプを曲げて、又は溶接等の手段により接合して形成される。実施の形態１においては、締め込み補助工具１００は、直径３０ｍｍの鋼製の円管により構成されている。 As shown in FIG. 1, the foundation portion 10, the first end portion 20, and the short portion 30 are arranged so that their central axes are on the same plane. That is, the central axes of the foundation portion 10, the first end portion 20, and the short portion 30 are arranged on the xy plane as shown in FIG. 1, respectively. The foundation portion 10, the first end portion 20, and the short portion 30 are made of steel pipes. That is, the tightening auxiliary tool 100 is formed by bending a steel pipe or joining them by means such as welding. In the first embodiment, the tightening auxiliary tool 100 is composed of a steel circular tube having a diameter of 30 mm.

図２は、実施の形態１に係る締め込み補助工具１００の使用状態の一例を示す図である。締め込み補助工具１００は、例えばボルト８１の頭部に形成された六角穴に六角レンチを挿し込んで締め付け又は緩めを行う際に用いるものである。図２は、ボルト８１の頭部をボルト８１の軸方向に沿った方向の視点から見た図であり、ボルト８１の頭部の六角穴には六角レンチ８０が挿し込まれた状態となっている。 FIG. 2 is a diagram showing an example of a usage state of the tightening auxiliary tool 100 according to the first embodiment. The tightening auxiliary tool 100 is used, for example, when a hexagon wrench is inserted into a hexagonal hole formed in the head of a bolt 81 to tighten or loosen the bolt. FIG. 2 is a view of the head of the bolt 81 as viewed from the viewpoint in the direction along the axial direction of the bolt 81, and the hexagon wrench 80 is inserted into the hexagonal hole of the head of the bolt 81. There is.

図２に示される様に、ボルト８１を締め込む場合、締め込み補助工具１００は、締め込み補助工具１００Ａの状態から締め込み補助工具１００Ｂに示される状態まで動かすことができる。締め込み補助工具１００Ａの状態と締め込み補助工具１００Ｂの状態とを比較すると、ボルト８１の中心を通る直線Ｃについて対称になっている。締め込み補助工具１００は、締め込み補助工具１００Ａの状態からボルト８１を締め込んでいき、障害物８３に締め込み補助工具１００が当接する前に、六角レンチ８０に挿し込んだまま六角レンチ８０の中心軸Ｃ１を中心として１８０°回転される。すると、締め込み補助工具１００は、反転して障害物８３との距離が確保され、さらに締め込むことができる。 As shown in FIG. 2, when tightening the bolt 81, the tightening auxiliary tool 100 can be moved from the state of the tightening auxiliary tool 100A to the state shown in the tightening auxiliary tool 100B. Comparing the state of the tightening auxiliary tool 100A and the state of the tightening auxiliary tool 100B, it is symmetrical with respect to the straight line C passing through the center of the bolt 81. The tightening auxiliary tool 100 tightens the bolt 81 from the state of the tightening auxiliary tool 100A, and before the tightening auxiliary tool 100 comes into contact with the obstacle 83, the hexagon wrench 80 is inserted into the hexagon wrench 80. It is rotated 180 ° about the central axis C1. Then, the tightening auxiliary tool 100 is inverted so that a distance from the obstacle 83 is secured, and the tightening auxiliary tool 100 can be further tightened.

図２に示されるように、締め込み補助工具１００は、障害物８２と障害物８３との間で、六角レンチ８０をθ３の角度だけ締め込むことができる。 As shown in FIG. 2, the tightening auxiliary tool 100 can tighten the hexagon wrench 80 between the obstacle 82 and the obstacle 83 by an angle of θ3.

図３は、実施の形態１に係る締め込み補助工具１００の比較例である締め込み補助工具１１００の使用状態を示す図である。比較例に係る締め込み補助工具１１００は、直線状の鋼製のパイプにより構成されている。この場合、締め込み補助工具１１００を六角レンチ８０と嵌合させて、ボルト８１を締め込むことが可能であるが、締め込み補助工具１１００は、締め込み補助工具１１００Ａの状態から締め込み補助工具１１００Ｂの状態までの範囲のみ移動可能である。このとき、六角レンチ８０及び締め込み補助工具１１００Ａの回転できる角度はθ４である。 FIG. 3 is a diagram showing a usage state of the tightening auxiliary tool 1100, which is a comparative example of the tightening auxiliary tool 100 according to the first embodiment. The tightening auxiliary tool 1100 according to the comparative example is composed of a straight steel pipe. In this case, the tightening auxiliary tool 1100 can be fitted with the hexagon wrench 80 to tighten the bolt 81, but the tightening auxiliary tool 1100 is the tightening auxiliary tool 1100B from the state of the tightening auxiliary tool 1100A. Only the range up to the state of can be moved. At this time, the rotatable angle of the hexagon wrench 80 and the tightening auxiliary tool 1100A is θ4.

図２及び図３を比較すると、締め込み補助工具１００によりボルト８１を締め込んだ場合の回転角度θ３は、比較例に係る締め込み補助工具１１００で締め込んだ場合の回転角度θ４よりも大きい。比較例に係る締め込み補助工具１１００は、直線状に形成されているため、障害物８３及び８４により一義的に移動可能な範囲が決まってしまう。一方、実施の形態１に係る締め込み補助工具１００は、六角レンチ８０の中心軸Ｃ１を中心として回転させることにより、障害物８３及び８４との接触を避けることができる。そのため、六角レンチ８０の締め込み量は、比較例よりも大きくなる。 Comparing FIGS. 2 and 3, the rotation angle θ3 when the bolt 81 is tightened by the tightening auxiliary tool 100 is larger than the rotation angle θ4 when the bolt 81 is tightened by the tightening auxiliary tool 1100 according to the comparative example. Since the tightening auxiliary tool 1100 according to the comparative example is formed in a straight line, the movable range is uniquely determined by the obstacles 83 and 84. On the other hand, the tightening auxiliary tool 100 according to the first embodiment can avoid contact with the obstacles 83 and 84 by rotating the hexagon wrench 80 around the central axis C1. Therefore, the tightening amount of the hexagon wrench 80 is larger than that of the comparative example.

図４及び図５は、実施の形態１に係る締め込み補助工具１００の使用状態の一例を示す図である。締め込み補助工具１００は、短尺部３０に設けられた第２端部３３及び第３端部３４を用いても、六角レンチ８０を動かすことができる。図４に示されているボルト８１を締める場合、作業領域Ｐに対しボルト８１が障害物８５の裏側に位置し、ボルト８１の上方にも障害物８４が配置されているため、締め込み補助工具１００は、締め込み補助工具１００Ｄの状態で設置される。このとき、第２端部３３と六角レンチ８０とが嵌合している。一方、締め込み補助工具１００Ｃの状態で六角レンチ８０と第３端部３４とを嵌合させた場合、上方に位置する障害物８４と締め込み補助工具１００Ｃとが接触してしまう。実施の形態１に係る締め込み補助工具１００は、六角レンチ８０を嵌合させることができる第１端部２０、第２端部３３、又は第３端部３４の３箇所有している。そのため、図４に示される様な、作業員が作業する作業領域Ｐからは狭くて入り組んだボルト８１の配置であっても、工具に設置できる自由度が高い。 4 and 5 are views showing an example of a usage state of the tightening auxiliary tool 100 according to the first embodiment. The tightening auxiliary tool 100 can also move the hexagon wrench 80 by using the second end portion 33 and the third end portion 34 provided on the short portion 30. When tightening the bolt 81 shown in FIG. 4, since the bolt 81 is located on the back side of the obstacle 85 with respect to the work area P and the obstacle 84 is also arranged above the bolt 81, the tightening auxiliary tool 100 is installed in the state of the tightening auxiliary tool 100D. At this time, the second end portion 33 and the hexagon wrench 80 are fitted. On the other hand, when the hexagon wrench 80 and the third end portion 34 are fitted in the state of the tightening auxiliary tool 100C, the obstacle 84 located above and the tightening auxiliary tool 100C come into contact with each other. The tightening auxiliary tool 100 according to the first embodiment has three locations, a first end portion 20, a second end portion 33, and a third end portion 34, to which the hexagon wrench 80 can be fitted. Therefore, even if the bolts 81 are arranged in a narrow and intricate manner from the work area P where the worker works as shown in FIG. 4, the degree of freedom of installation on the tool is high.

図５に示される様に、図４の締め込み補助工具１００Ｄの状態から六角レンチ８０を回した場合、締め込み補助工具１００Ｅは障害物８５と接触する。このとき、短尺部３０の第３端部３４と六角レンチ８０とを嵌合させるように、締め込み補助工具１００Ｆを設置することにより、六角レンチ８０を更に締め込み方向に回転させることができる。 As shown in FIG. 5, when the hexagon wrench 80 is turned from the state of the tightening auxiliary tool 100D of FIG. 4, the tightening auxiliary tool 100E comes into contact with the obstacle 85. At this time, the hexagon wrench 80 can be further rotated in the tightening direction by installing the tightening auxiliary tool 100F so as to fit the third end portion 34 of the short portion 30 and the hexagon wrench 80.

以上の様に、実施の形態１に係る締め込み補助工具１００は、工具と嵌合させる第１端部２０、第２端部３３、及び第３端部３４がそれぞれ開口されている方向が異なる。つまり、締め込み補助工具１００において、第１方向、第２方向、及び第３方向が異なった方向に設定されているため、周辺の障害物８２〜８５の配置に応じて、締め込み補助工具１００は工具と嵌合させることができる。 As described above, in the tightening auxiliary tool 100 according to the first embodiment, the directions in which the first end portion 20, the second end portion 33, and the third end portion 34 to be fitted with the tool are opened are different from each other. .. That is, in the tightening auxiliary tool 100, since the first direction, the second direction, and the third direction are set in different directions, the tightening auxiliary tool 100 is set according to the arrangement of the surrounding obstacles 82 to 85. Can be fitted with a tool.

また、実施の形態１に係る締め込み補助工具１００は、第１端部２０、第２端部３３、及び第３端部３４に対し、基礎部１０が長く形成されており、第１端部２０、第２端部３３、及び第３端部３４のうち何れを工具と嵌合させても、力を加え易い。そのため、締め込み補助工具１００によれば、ボルト８１の配置に拘わらず適正な締め付けトルクを確保でき、緩めることも可能となる。 Further, in the tightening auxiliary tool 100 according to the first embodiment, the foundation portion 10 is formed longer than the first end portion 20, the second end portion 33, and the third end portion 34, and the first end portion is formed. No matter which of 20, the second end 33, and the third end 34 is fitted with the tool, it is easy to apply a force. Therefore, according to the tightening auxiliary tool 100, an appropriate tightening torque can be secured regardless of the arrangement of the bolts 81, and the bolts can be loosened.

また、締め込み補助工具１００は、基礎部１０、第１端部２０、及び短尺部３０のそれぞれの中心軸が、同一面上に位置するため、コンパクトで障害物の隙間等に挿入する際、収納する際にも有利である。 Further, since the central axes of the foundation portion 10, the first end portion 20, and the short portion 30 of the tightening auxiliary tool 100 are located on the same surface, the tightening auxiliary tool 100 is compact and can be inserted into an obstacle gap or the like. It is also advantageous when storing.

以上に本発明を実施の形態に基づいて説明したが、本発明は上述した実施の形態の構成のみに限定されるものではない。例えば、基礎部１０と第１端部２０と短尺部３０とが成す角度は、変更することができる。また、基礎部１０、第１端部２０、及び短尺部３０の長さも変更しても良い。また、締め込み補助工具１００を構成する材料は、鋼以外のその他の金属製であっても良い。また、基礎部１０は、中空の部材に限定されず、中実の部材であっても良い。つまり、基礎部１０は、筒状部材又は棒状部材のどちらでも良い。さらに、第１端部２０及び短尺部３０は、筒状部材であれば、断面形状が円形でも多角形でも良い。要するに、いわゆる当業者が必要に応じてなす種々なる変更、応用、利用の範囲をも本発明の要旨（技術的範囲）に含むことを念のため申し添える。 Although the present invention has been described above based on the embodiments, the present invention is not limited to the configuration of the above-described embodiments. For example, the angle formed by the foundation portion 10, the first end portion 20, and the short portion 30 can be changed. Further, the lengths of the foundation portion 10, the first end portion 20, and the short portion 30 may be changed. Further, the material constituting the tightening auxiliary tool 100 may be made of a metal other than steel.
