Description

【0001】
【発明の属する技術分野】
本発明は、多角レンチ装置に関し、特に径が異なる断面積の複数の多角レンチを備え且つこの複数の多角レンチの中から所望のものを選択できるようにした多角レンチ装置に関する。
【0002】
【従来の技術】
異なる大きさの径のボルトの締めつけ作業を1本の多段式多角レンチで行うことができる、従来の多角レンチ装置は、径が大小複数の相似形の多角レンチを、最も小さい径の多角レンチを最も突出させるように順次突出させ、最も大きい径の多角レンチが最外側となるように、前記各多角レンチをテレスコピック形式で摺動自在に、かつ常時各々の軸方向に圧縮バネで偏倚し、突出させるように収納して構成されている(例えば、特許文献1参照)。
【0003】
【特許文献1】
特開平8−039443号公報 (第1〜5頁、図1〜9)
【0004】
【発明が解決しようとする課題】
しかしながら、上記した各多角レンチはテレスコピック形式で摺動されるように構成されるので、最も内側に位置する多角レンチ(つまり最も小さい径の多角レンチ)以外は、中空体としてしか形成し得ない。しかして、多角レンチ装置の外殻寸法は、狭小な空間での作業を予定している関係上、大きくさせるわけにはいかないので、中空体として形成された多角レンチの板厚は薄くならざるを得ない。かような多角レンチは締め付けトルクが弱く、家電製品におけるボルトの締め付けに使用する場合は格別、一般機械におけるボルトの締め付けに使用することは事実上、不可能であった。
【0005】
それ故に、本発明は、かような不具合が惹起されない多角レンチ装置を提供することを、その技術的課題とする。
【0006】
【課題を解決するための手段】
上記した課題を解決するために講じた技術的手段は、「一端部が把持部となる操作棒と、前記操作棒の他端部に一体回転可能に設けられた保持部と、前記操作棒の軸芯と直交する軸芯を持つように前記保持部材に回転可能に装架された回転軸と、前記回転軸上に固定されたドラム体と、前記ドラム体から放射状に延出し且つ径が異なる断面積の複数の多角レンチと、前記ドラム体及び前記回転軸を前記保持体に対して回動させて、前記複数の多角レンチのなかから所望のものを選択したあと前記ドラム体を前記保持体に固定する固定手段とを備える、多角レンチ装置」を構成したことである。
【0007】
【発明の実施の形態】
以下、添付図面に依拠して、本発明にかかる多角レンチ装置の一実施形態について説明する。
【0008】
図1及び図2に示すように、多角レンチ装置10は、操作棒12を備える。しかして、操作棒12の一方端部側は把持部12Aとして機能し、操作棒12の他方端部には、保持体20が固定される。すなわち、保持体20は、全体が略U字型をなすように、基部22並びに基部22の両端部から延出する一対の腕部24及び腕部26から形成されており、基部22が操作棒12の他方端部と螺着されることにより、保持体20が操作棒12の他方端部に固定される。
【0009】
回転軸30の両端部が、夫々、保持体20の一対の腕部24及び腕部26に、回転可能に支持される。回転軸30の一端部に形成されたフランジ部32は、腕部26の外面と係合しており、回転軸30の、腕24方向への移動を規制する。回転軸30の軸芯は、操作棒12の軸芯と直交関係にある。
【0010】
回転軸30の他端部は、腕部24の外側において、回転レバー40とスプライン係合(図示略)しており、回転レバー40は、回転軸30と一体回転可能であると共に回転軸30の他端部上を軸方向移動可能となる。すなわち、回転レバー40は、図の実線表示位置と破線表示位置との間を移動可能となる。
【0011】
回転軸30には、腕部24と腕部26との間において、ドラム体50がネジ(図示略)により、一体回転可能となるべく固着されている。ドラム体50の外周には90度間隔で4つの穴(図示略)が形成されており、この4つの穴には6角レンチ70、72、74及び76の基部が着脱自在に嵌着されている。6角レンチ70、72、74及び76の基部の径は全て同じであるが、基部以外は、6角レンチ70、72、74及び76の径は、異なる。
【0012】
回転レバー40を90度、180度、270度及び360度回動すると、回転軸30及びドラム体50も、回転レバー40の回動に追随すると共に、6角レンチ70、72、74及び76の軸芯が、操作棒12の軸芯と同芯となるようになっている。
【0013】
しかして、回転レバー40には、腕部24の遊端部近傍と対峙する位置に、突起42が形成されており、この突起42は、6角レンチ70、72、74及び76の軸芯が、操作棒12の軸芯と同芯となるとき、回転レバー40を破線位置から実線位置に移動すれば、腕部の外側に90度ピッチで形成された4つのブラインドボア80(1箇所のみ図示)内に挿入され、ドラム体50の回転が規制される。つまり、操作棒12の先端部に選択された6角レンチが同芯的に装着されることになり、右利きの作業者が、右手及び左手で、夫々、操作棒12の把持部及び他端部を握って所定角度、軸芯廻りに回動すれば、図示されないボルトを締め付けることが出来る。しかして、6角レンチ70、72、74及び76は、その基部をドラム体50に装着するだけなので、大部分を中空に形成するする必然性はない。つまり、6角レンチ70、72、74及び76は充分な肉厚を有することが出来て、充分に強度を保持でき、締め付けトルクを大きくすることが出来る。
【0014】
以上、本発明の実施の形態について説明したが、本発明は上述した実施の形態に限定される意図はなく、本発明の趣旨に沿った形態の多角レンチ装置であれば、どのようなものでもよい。
【0015】
【発明の効果】
請求項1の発明によれば、径が異なる断面積の複数の多角レンをドラム体から放射状に延出させるようにしているので、各多角レンチは充分な肉厚を有することが出来て、充分に強度を保持し、締め付けトルクを大きくすることが出来る。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a polygon wrench apparatus, and more particularly to a polygon wrench apparatus including a plurality of polygon wrenches having different cross-sectional areas with different diameters, and allowing a desired one to be selected from the plurality of polygon wrenches.
[0002]
[Prior art]
A conventional polygon wrench device capable of tightening bolts of different sizes with a single multi-stage polygon wrench. A conventional polygon wrench having a large or small diameter and a polygon wrench with the smallest diameter. Each polygonal wrench is slidably slid in a telescopic manner and always biased by a compression spring in the axial direction so that the polygonal wrench with the largest diameter is on the outermost side. (See, for example, Patent Document 1).
[0003]
[Patent Document 1]
JP-A-8-039443 (pages 1 to 5, FIGS. 1 to 9)
[0004]
[Problems to be solved by the invention]
However, since each of the above-mentioned polygonal wrenches is configured to be slid in a telescopic manner, only the innermost polygonal wrench (that is, the polygonal wrench having the smallest diameter) can be formed only as a hollow body. However, since the outer shell dimensions of the polygon wrench device cannot be increased due to the planned work in a small space, the thickness of the polygon wrench formed as a hollow body must be reduced. I can't get it. Such a polygon wrench has a low tightening torque, and when used for tightening bolts in home electric appliances, it is practically impossible to use it for tightening bolts in general machines.
[0005]
Therefore, an object of the present invention is to provide a polygon wrench device in which such a problem is not caused.
[0006]
[Means for Solving the Problems]
The technical means taken to solve the above-mentioned problem includes: an operation rod having one end serving as a gripping part, a holding part provided at the other end of the operation rod so as to be integrally rotatable, A rotating shaft rotatably mounted on the holding member so as to have an axis perpendicular to the axis, a drum body fixed on the rotating shaft, and radially extending from the drum body and having different diameters A plurality of polygonal wrenches having a sectional area, the drum body and the rotating shaft are rotated with respect to the holding body, and a desired one is selected from the plurality of polygonal wrenches. And a fixing means for fixing the wrench to the polygon wrench.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a polygon wrench device according to the present invention will be described with reference to the accompanying drawings.
[0008]
As shown in FIGS. 1 and 2, the polygon wrench device 10 includes an operation rod 12. Thus, one end of the operation rod 12 functions as a gripper 12A, and the holder 20 is fixed to the other end of the operation rod 12. That is, the holding body 20 is formed of a base 22 and a pair of arms 24 and 26 extending from both ends of the base 22 so that the entire body forms a substantially U-shape. The holding body 20 is fixed to the other end of the operation rod 12 by being screwed to the other end of the operation rod 12.
[0009]
Both ends of the rotating shaft 30 are rotatably supported by the pair of arms 24 and 26 of the holder 20, respectively. A flange 32 formed at one end of the rotating shaft 30 is engaged with the outer surface of the arm 26, and regulates the movement of the rotating shaft 30 in the direction of the arm 24. The axis of the rotation shaft 30 is orthogonal to the axis of the operation rod 12.
[0010]
The other end of the rotating shaft 30 is spline-engaged (not shown) with the rotating lever 40 outside the arm 24, and the rotating lever 40 can rotate integrally with the rotating shaft 30, and It becomes axially movable on the other end. That is, the rotary lever 40 can move between the solid line display position and the broken line display position in the figure.
[0011]
A drum body 50 is fixed to the rotating shaft 30 between the arm 24 and the arm 26 by a screw (not shown) so as to be integrally rotatable. Four holes (not shown) are formed at 90-degree intervals on the outer periphery of the drum body 50, and bases of hexagonal wrenches 70, 72, 74, and 76 are detachably fitted into these four holes. I have. The diameters of the bases of the hex wrenches 70, 72, 74 and 76 are all the same, but the diameters of the hex wrenches 70, 72, 74 and 76 are different except for the base.
[0012]
When the rotation lever 40 is rotated by 90 degrees, 180 degrees, 270 degrees, and 360 degrees, the rotation shaft 30 and the drum body 50 also follow the rotation of the rotation lever 40, and the hex wrenches 70, 72, 74, and 76 The axis is concentric with the axis of the operation rod 12.
[0013]
The rotation lever 40 has a projection 42 formed at a position facing the vicinity of the free end of the arm 24. The projection 42 has an axis of the hexagonal wrench 70, 72, 74, or 76. When the rotary lever 40 is moved from the position indicated by the broken line to the position indicated by the solid line when the operating rod 12 is concentric with the axis of the operating rod 12, four blind bores 80 formed at a 90-degree pitch outside the arm (only one is shown) ), The rotation of the drum body 50 is regulated. In other words, the selected hexagon wrench is concentrically attached to the tip of the operating rod 12, and the right-handed worker can use the right and left hands to grip the operating rod 12 and the other end, respectively. By gripping the part and rotating it about the axis by a predetermined angle, a bolt (not shown) can be tightened. However, the hexagonal wrenches 70, 72, 74 and 76 do not need to be largely hollow because the bases thereof are merely mounted on the drum body 50. That is, the hexagonal wrenches 70, 72, 74, and 76 can have a sufficient thickness, maintain sufficient strength, and can increase a tightening torque.
[0014]
As described above, the embodiments of the present invention have been described. However, the present invention is not intended to be limited to the above-described embodiments, and any polygon wrench device having a form in accordance with the gist of the present invention may be used. Good.
[0015]
【The invention's effect】
According to the first aspect of the present invention, a plurality of polygonal wrenches having different diameters in cross-sectional area are radially extended from the drum body. Therefore, each polygonal wrench can have a sufficient wall thickness, And the tightening torque can be increased.
