It is not a thing.

この電動ドライバ１は、本体部２と、把持部３と、電源部４を備える。本体部２は筒状のハウジング２１を有する。このハウジング２１の内部に、図４に示すように、駆動源であるモータ２２、回転力を伝達するスピンドル２３、打撃力を生じさせるハンマ機構２４等が収納されている。尚、本体部２における内部機構の構造に関しては従来どおりであることから、詳細な説明は行わない。本体部２の正面からはチャック部２５が突出しており、このチャック部２５に、作業時において締結部材に接続されるビット（図示しない）を取り付けることができる。   The electric driver 1 includes a main body portion 2, a grip portion 3, and a power supply portion 4. The main body 2 has a cylindrical housing 21. As shown in FIG. 4, the housing 21 houses a motor 22 that is a driving source, a spindle 23 that transmits rotational force, a hammer mechanism 24 that generates striking force, and the like. Since the structure of the internal mechanism in the main body 2 is the same as the conventional structure, detailed description will not be given. A chuck portion 25 protrudes from the front surface of the main body portion 2, and a bit (not shown) connected to a fastening member during operation can be attached to the chuck portion 25.

把持部３は、本体部２から径外方向に延びており、作業時等に作業者が把持する部分である。把持部３における本体部２寄り端部における正面側にはトリガスイッチ３１が設けられている。作業者はこのトリガスイッチ３１を押し込むことにより、チャック部２５に取り付けられたビットを所望の回転数で回転させることができる。また、本体部２における把持部３との境界部分には、回転方向を正転方向と逆転方向とに切り換えるための切り換えスイッチ２６が設けられている。図１に示すように、この切り換えスイッチ２６は左右両側面に突出しており、作業者が押し込むことができるように構成されている。また、把持部３には、図示していないが制御基板が内蔵されている。   The grip portion 3 extends from the main body portion 2 in the radially outward direction, and is a portion that is gripped by an operator during work. A trigger switch 31 is provided on the front side of the grip portion 3 near the main body portion 2. The operator can rotate the bit attached to the chuck portion 25 at a desired rotational speed by pressing the trigger switch 31. A changeover switch 26 for switching the rotation direction between the forward rotation direction and the reverse rotation direction is provided at a boundary portion of the main body 2 with the grip portion 3. As shown in FIG. 1, the changeover switch 26 protrudes from both the left and right side surfaces, and is configured to be pushed by the operator. Moreover, although not shown in figure, the control board is incorporated in the holding part 3. FIG.

電源部４は、把持部３における本体部２とは反対側の端部（図示下端部）に位置しており、電源である電池パック４１を着脱可能に保持している。尚、電動ドライバ１に外部からコード等を介して電力を供給するよう構成することもでき、その場合には電池パック４１を設けないようにもできる。   The power supply unit 4 is located at the end (the lower end in the figure) of the gripping unit 3 opposite to the main body 2 and holds a battery pack 41 that is a power supply in a detachable manner. In addition, it can also comprise so that electric power may be supplied to the electric driver 1 via a code | cord | chord etc. from the outside, and it can also be made not to provide the battery pack 41 in that case.

本体部２におけるハウジング２１は、側面に径方向へ膨出した膨出部５を有する。本実施形態では、図１に示すように、ハウジング２１の右側面(正面から見た場合であって、作業者から見ると左側面となる)が左側面よりもスピンドル２３及びチャック部２５の回転中心（径中心）を基準に径外位置に張り出している。この張り出した部分が膨出部５である。本実施形態における膨出部５の形状は、図２に示すように、正面側が幅広であり背面側が幅狭に形成された略台形状、または、横倒しの「Ａ」字形状である。図３に示すように、デザイン上の観点により、膨出部５の相当部分９は左側面にも形成されているが、ハウジング２１から径外位置（図１における左右方向）への張り出し量は、左側面における相当部分９よりも右側面における膨出部５の方が大きくなっている。ただし、膨出部５の形状はこれに限定されず、種々の形状とできる。また、本実施形態の膨出部５には、エラストマー等の軟質樹脂で形成されたカバー部２９が含まれる。このカバー部２９により、ハウジング２１の内外を連通する隙間を生じないようにできるため、ハウジング２１の内部に粉塵等が侵入して本体部２の内部機構が故障することを抑制できる。   The housing 21 in the main body 2 has a bulging portion 5 bulging in the radial direction on the side surface. In the present embodiment, as shown in FIG. 1, the right side surface of the housing 21 (when viewed from the front and the left side when viewed from the operator) is the rotation of the spindle 23 and the chuck portion 25 rather than the left side surface. Projects to the outer diameter position with the center (diameter center) as a reference. This protruding portion is the bulging portion 5. As shown in FIG. 2, the shape of the bulging portion 5 in the present embodiment is a substantially trapezoidal shape in which the front side is wide and the back side is narrow, or a sideways “A” shape. As shown in FIG. 3, the corresponding portion 9 of the bulging portion 5 is also formed on the left side surface from the viewpoint of design, but the amount of protrusion from the housing 21 to the radially outside position (left-right direction in FIG. 1) is The bulging portion 5 on the right side is larger than the corresponding portion 9 on the left side. However, the shape of the bulging part 5 is not limited to this, and can be various shapes. Further, the bulging portion 5 of the present embodiment includes a cover portion 29 formed of a soft resin such as an elastomer. Since this cover part 29 can prevent a gap communicating between the inside and outside of the housing 21, it is possible to prevent dust and the like from entering the inside of the housing 21 and failure of the internal mechanism of the main body part 2.

膨出部５は、ハウジング２１の側面において径方向に貫通した開口である窓部６と、窓部６を囲む窓枠部７を備える。本実施形態における窓部６は、図５及び図６に示すように、ハウジング２１の内部に位置しており前記ハンマ機構２４等を保持するギアケース２７の、更に径外方向に位置する支持部材２８であって、運転操作部８（後述）を支持する支持部材２８に形成されている開口である。この支持部材２８は、カバー部２９の縁部と共に、ハウジング２１とギアケース２７とに挟持されている。本実施形態の窓部６はカバー部２９の一部により覆われている。そして、窓部６に対応するようにロゴ６Ｌ（図示の「Ｒ」は一例であって、ロゴの形状は限定されない）が設けられ、このロゴ６Ｌの部分が半透明とされている（透明であってもよい）。そして、ロゴ６Ｌの部分以外は不透明である。このロゴ６Ｌを通して、運転操作部８における点灯部８２が発する光を本体部２の外部から視認できる。   The bulging portion 5 includes a window portion 6 that is an opening penetrating in the radial direction on the side surface of the housing 21, and a window frame portion 7 that surrounds the window portion 6. As shown in FIGS. 5 and 6, the window portion 6 in the present embodiment is located inside the housing 21 and is a support member that is located further radially outward of the gear case 27 that holds the hammer mechanism 24 and the like. 28 is an opening formed in the support member 28 that supports the operation unit 8 (described later). The support member 28 is sandwiched between the housing 21 and the gear case 27 together with the edge portion of the cover portion 29. The window portion 6 of this embodiment is covered with a part of the cover portion 29. A logo 6L ("R" in the figure is an example and the shape of the logo is not limited) is provided so as to correspond to the window portion 6, and the logo 6L is translucent (transparent May be). The portions other than the logo 6L are opaque. Through this logo 6L, the light emitted from the lighting part 82 in the driving operation part 8 can be visually recognized from the outside of the main body part 2.

窓枠部７は、膨出部５の外縁に一致して形成され、図５及び図６に示すように、他の部分よりも一段高く突出した部分である。本実施形態の窓枠部７は、カバー部２９の一部として形成されており、側面視にて窓部６の周囲に位置している。尚、本実施形態ではデザイン上の観点により、前記略台形状である底辺部分の両端から正面側へと突出した部分が延長されているが、この部分は設けないこともできる。また、本実施形態では膨出部５の形成領域と窓部６及び窓枠部７の形成領域とが一致しているが、これに限定されず、膨出部５の形成領域の一部に窓部６及び窓枠部７が形成されていてもよい。   The window frame portion 7 is formed so as to coincide with the outer edge of the bulging portion 5 and protrudes one step higher than the other portions as shown in FIGS. 5 and 6. The window frame portion 7 of the present embodiment is formed as a part of the cover portion 29 and is located around the window portion 6 in a side view. In the present embodiment, from the viewpoint of design, the portions that protrude from both ends of the substantially trapezoidal bottom portion to the front side are extended, but this portion may not be provided. Further, in the present embodiment, the formation region of the bulging portion 5 and the formation region of the window portion 6 and the window frame portion 7 are the same. The window part 6 and the window frame part 7 may be formed.

膨出部５には、作業者により運転に関する操作がなされる運転操作部８が設けられている。運転に関する操作の一例としては、トリガスイッチ３１を最大に押し込んだ場合の最高回転数の設定に関する操作が挙げられるが、その他種々の運転モードの設定に関する操作が該当する。また、前記運転モードの他、例えば、運転の際にビット周辺を照らすための照明装置の点灯・消灯を行う等、電動ドライバ１の運転を補助できる種々の操作を行うことができる。本実施形態の運転操作部８は、作業者が押すことで複数の運転モード等を選択できる押しボタン式スイッチであるが、これに限定されず、運転操作部８には、スライドスイッチやタッチパネル等、種々の構成を有するスイッチ類を採用できる。   The bulging portion 5 is provided with a driving operation portion 8 where an operation related to driving is performed by an operator. An example of the operation related to the operation is an operation related to the setting of the maximum number of revolutions when the trigger switch 31 is pushed in to the maximum, and other operations related to the setting of various operation modes are applicable. In addition to the operation mode, various operations that can assist the operation of the electric driver 1 can be performed, such as turning on / off the illumination device for illuminating the periphery of the bit during operation. The driving operation unit 8 of the present embodiment is a push button type switch that can be selected by a worker to select a plurality of operation modes, but is not limited thereto, and the driving operation unit 8 includes a slide switch, a touch panel, and the like. The switches having various configurations can be employed.

本実施形態では、膨出部５の内部に設けられた支持部材２８に運転操作部８が支持されている。運転操作部８及び支持部材２８はカバー部２９により覆われている。膨出部５は、ハウジング２１から径外位置に張り出しているため、作業者から見て隠れにくい位置に存在するので、作業者は、運転操作部８がどこにあるか一目でわかる。このため、従来のように把持部３、及び、把持部３を握った作業者の手により隠れてしまうことがない。よって、従来の、運転操作部８に相当するスイッチが電源部４における前方上面に設けられていた構成（特許文献１参照）のように、運転操作部８を操作する際に把持部３を持ち換えたり、両手で操作したりする必要がない。従って、運転操作部８の視認性及び操作性が良い。また、膨出部５はハウジング２１の側面に設けられるため、広い面積で形成することが可能である。このため、膨出部５に合わせて運転操作部８を大きく形成することにより、操作性を更に向上できる。   In the present embodiment, the driving operation unit 8 is supported by the support member 28 provided inside the bulging unit 5. The driving operation unit 8 and the support member 28 are covered with a cover unit 29. Since the bulging portion 5 protrudes from the housing 21 to a position outside the diameter, the bulging portion 5 is present at a position that is difficult to hide from the operator, so that the operator can know at a glance where the driving operation portion 8 is. For this reason, it is not hidden by the grip part 3 and the operator's hand holding the grip part 3 as in the conventional case. Therefore, like the conventional configuration in which the switch corresponding to the driving operation unit 8 is provided on the front upper surface of the power supply unit 4 (see Patent Document 1), the holding unit 3 is held when the driving operation unit 8 is operated. There is no need to change or operate with both hands. Therefore, the visibility and operability of the driving operation unit 8 are good. Moreover, since the bulging part 5 is provided in the side surface of the housing 21, it can be formed in a wide area. For this reason, the operability can be further improved by forming the driving operation portion 8 to be large in accordance with the bulging portion 5.

運転操作部８は、作業者が把持部３を把持したまま指が届く位置に設けられている。この位置は、具体的には、作業者の親指を除く指で把持部３を把持した状態における、親指の可動範囲に少なくとも一部が重なる位置である。尚、前記可動範囲は、電動ドライバ１の販売対象地域における人種の平均的な手指の大きさを基準として定めることができる。   The driving operation unit 8 is provided at a position where the operator can reach the finger while holding the holding unit 3. Specifically, this position is a position at least partially overlapping the movable range of the thumb in a state in which the grip portion 3 is gripped with fingers other than the operator's thumb. The movable range can be determined based on the average finger size of the race in the sales target area of the electric driver 1.

運転操作部８は操作状態（作業者の操作により選択された運転モード等）を視覚的に表示する表示部８１を備える。本実施形態の表示部８１は、操作状態を複数の点灯態様で区別して表示できる点灯部８２を備える。点灯部８２はＬＥＤを備えており、操作状態に応じた色彩で点灯する。尚、操作状態は色彩により表示する以外に、色彩が同一であって異なる点灯パターン（例えば点滅）で表示することもできる。更に、色彩と点灯パターンとを組み合わせることもでき、点灯態様は限定されない。このように点灯部８２の点灯で操作状態を区別して表示するため、光で作業者に操作状態を報知できる。このため、視認性が更に良くなる。   The driving operation unit 8 includes a display unit 81 that visually displays an operation state (such as an operation mode selected by an operator's operation). The display unit 81 of the present embodiment includes a lighting unit 82 that can distinguish and display the operation state in a plurality of lighting modes. The lighting unit 82 includes an LED and lights up with a color corresponding to the operation state. In addition to displaying the operation state by color, the operation state can also be displayed by different lighting patterns (for example, blinking) with the same color. Furthermore, a color and a lighting pattern can also be combined, and the lighting mode is not limited. Thus, since the operation state is distinguished and displayed by the lighting of the lighting unit 82, the operator can be notified of the operation state with light. For this reason, the visibility is further improved.

表示部８１は膨出部５において径方向に貫通した窓部６に臨むように配置される。この配置状態にて、操作状態が視覚的に表示される。本実施形態では、窓部６に対応して設けられた半透明のロゴ６Ｌを通して、点灯部８２の色彩が表示される。このため、視認性が良い。特に本実施形態では、他の部分よりも一段高く突出した窓枠部７に囲まれるように表示部８１が位置するため、視覚的に目立つ窓枠部７に作業者の視線が向かいやすくなることから、視認性を更に良くできる。そして、窓枠部７は一段高く突出した部分であるから、作業者は触覚により運転操作部８の位置を把握できる。このため、作業者はいちいち膨出部５に視線を移さなくても、「手さぐり」で運転操作部８を操作することもできる。   The display part 81 is arranged so as to face the window part 6 penetrating in the radial direction in the bulging part 5. In this arrangement state, the operation state is visually displayed. In the present embodiment, the color of the lighting part 82 is displayed through a semi-transparent logo 6L provided corresponding to the window part 6. For this reason, visibility is good. In particular, in the present embodiment, the display unit 81 is positioned so as to be surrounded by the window frame portion 7 that protrudes one step higher than the other portions, so that the operator's line of sight can easily face the visually conspicuous window frame portion 7. Therefore, the visibility can be further improved. And since the window frame part 7 is the part which protruded one step higher, the operator can grasp | ascertain the position of the driving | operation operation part 8 by tactile sense. For this reason, the operator can also operate the driving operation unit 8 by “hand scissors” without shifting the line of sight to the bulging unit 5 one by one.

また、窓枠部７は、運転操作部８よりもハウジング２１の径方向へ更に膨出している。このため、窓枠部７に対して運転操作部８が凹んだ位置にある。よって、例えば不意に物体が当たった際でも運転操作部８に物体が当たる可能性を減少させることができ、誤動作を抑制できる。尚、窓枠部７と運転操作部８との位置関係はこれに限定されず、例えば、窓枠部７に対して運転操作部８が同一高さとすることもできる。   Further, the window frame portion 7 further bulges in the radial direction of the housing 21 as compared with the driving operation portion 8. For this reason, the driving operation portion 8 is in a recessed position with respect to the window frame portion 7. Therefore, for example, even when an object hits unexpectedly, the possibility that the object hits the driving operation unit 8 can be reduced, and malfunction can be suppressed. The positional relationship between the window frame portion 7 and the driving operation portion 8 is not limited to this, and for example, the driving operation portion 8 can have the same height with respect to the window frame portion 7.

以上、本実施形態について説明した。しかし、本発明に係る電動ドライバ１は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変更が可能である。   The present embodiment has been described above. However, the electric driver 1 according to the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.
