Can be provided.

<第1の実施形態>
本発明を電動工具に適用した第1の実施形態を図1乃至図5を用いて説明する。図1は、ハウジング2及びプロテクタ3などの外枠を有するインパクトドライバであるが、略T字形状を成しており、ハウジング2によって形成される本体胴体部4には電気或いは空気式の駆動源であるモータや減速機構部を構成する遊星ギヤ部(図示省略)などを収容し、且つ本体胴体部4から垂下するハンドル握り部5にはモータに電力を供給するためのトリッガスイッチ6やバッテリ7の接続端子と電気的に接続される接点などが収容されている。
<First Embodiment>
A first embodiment in which the present invention is applied to a power tool will be described with reference to FIGS. FIG. 1 shows an impact driver having an outer frame such as a housing 2 and a protector 3. The impact driver has a substantially T shape, and an electric or pneumatic drive source is provided in a main body body 4 formed by the housing 2. A trigger gear 6 and a battery 7 for supplying electric power to the motor are accommodated in a handle grip part 5 that suspends the motor, a planetary gear part (not shown) constituting the speed reduction mechanism part, and the like, and hangs down from the body body part 4. The contact etc. which are electrically connected with the connection terminal are accommodated.

また、ハウジング2に当接して配置されるプロテクタ3内にはモータの回転動力を打撃力に変換するための打撃機構部及びビット等を保持するための先端工具保持部8などが収容されている。上記インパクトドライバのハンドル握り部5の下部には、抜け止め防止機能をもち、作業者のベルト等に掛止可能なフックとしての機能を有するナスカン9と、ナスカン9を固定するためのナスカン保持部10が配設されている。   Further, the protector 3 disposed in contact with the housing 2 accommodates an impact mechanism portion for converting the rotational power of the motor into impact force, a tip tool holding portion 8 for holding a bit and the like. . At the lower part of the handle grip portion 5 of the impact driver, there is an anti-removal function, and an eggplant 9 that functions as a hook that can be hooked on an operator's belt or the like, and an eggplant holder for fixing the eggplant 9 10 is disposed.

図2乃至図5を用いてナスカン9及びナスカン保持部10の構造について具体的に説明する。図2は図1の部分拡大図、図3は図2の側面図、図4は図2のA−A断面図でナスカン9固定状態、図5は図2のA−A断面図でナスカン9を取外した状態である。ナスカン保持部10の構成部品であるベース11は、ハウジング2内に設けられたナット(図示せず)と、ベース止めネジ12によりハウジング2に固定されている。ベース11にはカバー13の突起部13aを通し、はめ込むための穴11aが設けられており、穴11aにカバーの突起部13aをはめ込んでカバー13の一端を抑え、もう一端はカバー止めネジ14でベース11とカバー13を連結する構造となっている。なお、ナスカン9の交換は固定部材であるカバー止めネジ14を取り外すことによって、カバー13が外れるので、簡単に交換することができる。   The structure of the eggplant 9 and the eggplant holder 10 will be specifically described with reference to FIGS. 2 is a partially enlarged view of FIG. 1, FIG. 3 is a side view of FIG. 2, FIG. 4 is a sectional view taken on line AA of FIG. It is the state which removed. A base 11, which is a component part of the eggplant holder 10, is fixed to the housing 2 by a nut (not shown) provided in the housing 2 and a base set screw 12. The base 11 is provided with a hole 11a through which the protrusion 13a of the cover 13 is inserted and fitted. The protrusion 11a of the cover is inserted into the hole 11a to suppress one end of the cover 13, and the other end is a cover set screw 14. The base 11 and the cover 13 are connected. The replacement of the eggplant 9 can be easily replaced because the cover 13 is removed by removing the cover set screw 14 which is a fixing member.

ここで、ナスカン9はベース11とカバー13の間に弾性体15を介して配設されている。弾性体15を介してナスカン9を配設することで、次の2つの利点がある。1つは、弾性体15は、ナスカン9の直径φの大きさに応じて変形してくれるので、作業者は任意の大きさのナスカン9を自由に装着することが可能である。2つは、弾性体15は常にナスカン9を付勢しているので、図4のように作業者が任意の角度に回動が可能であり、ナスカン9で腰ベルト等に掛止しない場合は、ナスカン9を図4に示した(a)の位置や(b)の位置に配置することで、工具本体を使用する場合に、邪魔にならず取り回しもよい。   Here, the eggplant 9 is disposed between the base 11 and the cover 13 via an elastic body 15. By arranging the eggplant 9 via the elastic body 15, there are the following two advantages. One is that the elastic body 15 is deformed according to the diameter φ of the eggplant 9 so that the operator can freely attach the eggplant 9 of an arbitrary size. Secondly, since the elastic body 15 always urges the eggplant 9, the operator can rotate it at an arbitrary angle as shown in FIG. By arranging the eggplant 9 at the position (a) or the position (b) shown in FIG.

次に、ナスカン9の構造について説明する。ナスカンのレバー9aはレバーに内蔵されたスプリング(図示省略)によって、常に(c)方向に付勢されている。ナスカン9を作業者の腰ベルト等に掛止する場合は、レバー9aを(d)方向に移動させ、腰ベルト等にナスカン9を通す。ナスカン9が通ったあとレバー9aを離せば、内蔵されたスプリングによってレバー9aは元の位置に戻り、ナスカン9が腰ベルト等から外れる心配はなくなる。このように、ナスカン9と、ナスカン9を固定するためのナスカン保持部10を備えた電動工具を用いれば、どのような作業や移動時にも作業者の腰ベルト等から外れることがない安全性の高く、作業者がナスカン9を邪魔にならない位置へ任意に回動することができる電動工具を提供することができる。
<第2の実施形態>
第2の実施形態を図6、7を用いて説明する。図6は、図2の変形例を示す正面図であり、図7は、図6のB−B断面図である。この実施例では、カバー13の形状を一部変形させ板バネ13bとしての機能を持たせてある。この板バネ13bは常にナスカン9を付勢させているので、前記弾性体15と同様の機能を持たせることができる。よって別部品として弾性体15を設ける必要なくなるので、安価で安全性、作業性にすぐれた電動工具を提供することができる。
<第3の実施形態>
第3の実施形態を図8、9を用いて説明する。図8は、図2の変形例を示す正面図であり、図9は、図8のC−C断面図である。この実施例では、ベース11に数箇所の穴11aを設け、カバー13には変形可能なカエリ13bが設けてある。ベース11に設けた穴11aにカバーのカエリ13bを変形させながら挿入し、穴11aを通りきったら変形が開放されカバー13とベース11が連結される構造となっている。この構造にすることで、カバー13とベース11を連結するカバー止めネジ14が不要になるため、簡単な構造且つ安価にすることができる。
Next, the structure of the NASCAN 9 will be described. The lever 9a of the eggplant is always urged in the direction (c) by a spring (not shown) built in the lever. When hooking the eggplant 9 on an operator's waist belt or the like, the lever 9a is moved in the direction (d), and the eggplant 9 is passed through the waist belt or the like. If the lever 9a is released after the eggplant 9 has passed, the lever 9a is returned to its original position by the built-in spring, and there is no fear that the eggplant 9 will come off the waist belt or the like. In this way, if the power tool provided with the eggplant 9 and the eggplant holder 10 for fixing the eggplant 9 is used, the safety of the worker's waist belt and the like will not come off during any work or movement. It is possible to provide a high-powered electric tool that allows an operator to arbitrarily rotate the eggplant 9 to an unobstructed position.
<Second Embodiment>
A second embodiment will be described with reference to FIGS. 6 is a front view showing a modification of FIG. 2, and FIG. 7 is a cross-sectional view taken along the line BB of FIG. In this embodiment, the cover 13 is partially deformed to have a function as a leaf spring 13b. Since the leaf spring 13b always urges the eggplant 9, it can have the same function as the elastic body 15. Therefore, since it is not necessary to provide the elastic body 15 as a separate part, it is possible to provide an electric tool that is inexpensive, excellent in safety and workability.
<Third Embodiment>
A third embodiment will be described with reference to FIGS. FIG. 8 is a front view showing a modification of FIG. 2, and FIG. 9 is a cross-sectional view taken along the line CC of FIG. In this embodiment, the base 11 is provided with several holes 11a, and the cover 13 is provided with a deformable burr 13b. The cover burrs 13b are inserted into the holes 11a provided in the base 11 while being deformed. After passing through the holes 11a, the deformation is released and the cover 13 and the base 11 are connected. By adopting this structure, the cover set screw 14 for connecting the cover 13 and the base 11 is not necessary, so that the structure can be simplified and the cost can be reduced.

第1〜3の実施形態では電動工具の一例としてインパクトドライバを用いて説明したが、インパクトドライバに限定されるものではなく、ドライバドリル、釘打機、丸鋸等その他の電動工具にも適用可能である。   In the first to third embodiments, the impact driver is used as an example of the power tool. However, the present invention is not limited to the impact driver, and can be applied to other power tools such as a driver drill, a nailing machine, and a circular saw. It is.
