Description

本発明は、照明のためのライトを備えているライト付き電動工具に関するものである。   The present invention relates to an electric tool with a light including a light for illumination.

暗所での作業を容易にするために、作業対象箇所を照らすためのライトを備えている電動工具がある（特許文献１参照）。この場合、ライトは工具ビット先端付近を効率良く照らすために、特許文献１にも示されているように、電動工具における出力軸を保持している駆動部ケースの外周部に配置することになる。   In order to facilitate work in a dark place, there is an electric tool provided with a light for illuminating a work target location (see Patent Document 1). In this case, in order to efficiently illuminate the vicinity of the tip of the tool bit, the light is arranged on the outer peripheral portion of the drive unit case holding the output shaft in the electric tool as shown in Patent Document 1. .

しかし、電動工具がインパクトドライバーのような振動を伴うものである場合、金属製である上記駆動部ケースは、振動や熱を伝えやすいことから、ライトの発光部やリード線が断線したり焼き切れたりする虞が高いものとなっている。   However, when the power tool is accompanied by vibration like an impact driver, the drive case made of metal is easy to transmit vibration and heat, so the light emitting part and the lead wire of the light are disconnected or burnt out. There is a high risk of losing.

また、駆動部ケースの断面形状が円形の場合、その外周面にライトを隙間無く装着することが困難であり、これ故に生じた隙間からエッジのある異物が入って断線したり、水が入ってショートしてしまう虞がある。
特開２００３−１４５４３９号公報 Also, if the drive unit case has a circular cross-sectional shape, it is difficult to mount the light without any gap on its outer peripheral surface. There is a risk of short circuit.
JP 2003-145439 A

本発明は上記の従来の問題点に鑑みて発明したものであって、ライトを振動や熱から保護することができるとともに、防塵防水性を高めることができるライト付き電動工具を提供することを他の課題とするものである。   The present invention has been invented in view of the above-described conventional problems, and provides a light-equipped electric tool capable of protecting a light from vibration and heat and improving dustproof and waterproof properties. It is set as an issue.

上記課題を解決するために本発明は、出力部を覆っている駆動部ケースの外面に、作業対象箇所の照明用のライトを配しているライト付き電動工具において、上記ライトと駆動部ケースの外面との間に弾性体を介在させているとともに、上記弾性体が駆動部ケースの外面を被覆している保護カバーであることに特徴を有している。駆動部ケースからの振動や熱の影響を受けにくくしたものであり、また弾性体の存在により、駆動部ケース外面へのライトの装着を隙間無く行うことを容易にしたものである。 In order to solve the above problems, the present invention provides an electric tool with a light in which a light for illuminating a work target portion is arranged on an outer surface of a drive unit case covering an output unit. The elastic body is interposed between the outer surface and the elastic body is a protective cover that covers the outer surface of the drive unit case . It is made less susceptible to vibrations and heat from the drive unit case, and the presence of the elastic body makes it easy to mount the light on the outer surface of the drive unit case without any gaps.

上記弾性体には、駆動部ケースの外面を被覆している保護カバーを流用することができる。   A protective cover covering the outer surface of the drive unit case can be used for the elastic body.

また、上記弾性体が断熱性を有していると、熱の影響をより確実に避けることができる。   Moreover, when the elastic body has a heat insulating property, the influence of heat can be avoided more reliably.

本発明は、ライトと駆動部ケースの外面との間に介在している弾性体が、駆動部ケースからの振動や熱の影響がライトに生じることを抑制するために、ライトを振動や熱から保護することができて、ライトの断線や焼き切れ等を防ぐことができるものであり、また弾性体の存在により、駆動部ケース外面へのライトの装着を隙間無く行うことが容易となって、ライト回りの防塵防水性を高めることができる。   In the present invention, the elastic body interposed between the light and the outer surface of the drive unit case prevents the vibration and heat from the drive unit case from affecting the light. It is possible to protect and prevent disconnection, burnout, etc. of the light, and the presence of the elastic body makes it easy to attach the light to the outer surface of the drive unit case without gaps, Dust proofing and waterproofing around the light can be improved.

以下、本発明を添付図面に示す実施形態に基いて説明すると、図２に示す電動工具は、モータ及び駆動機構を内蔵する本体部１と一体のグリップ部１０の下端に電池パック１５を着脱自在に装着した電動インパクトドライバーであり、グリップ１０の上端部にトリガースイッチ１６と回転方向切換レバー１７とを備えており、本体部１の前端にはドライバービット９を保持するチャック２０を備えている。図２中の１９はグリップ部１０の下端部に配設したフックである。   Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. In the electric tool shown in FIG. 2, a battery pack 15 is detachably attached to a lower end of a grip portion 10 integral with a main body portion 1 incorporating a motor and a drive mechanism. The trigger switch 16 and the rotation direction switching lever 17 are provided at the upper end of the grip 10, and the chuck 20 that holds the driver bit 9 is provided at the front end of the main body 1. Reference numeral 19 in FIG. 2 denotes a hook disposed at the lower end of the grip portion 10.

上記本体部１及びグリップ部１０は、左右二つ割のハウジング１ａ，１ｂに、出力軸２が先端から突出するインパクト駆動機構３を覆う駆動部ケース１１を連結したものとして形成されており、金属製である駆動部ケース１１の外面には保護カバー１３，１４が装着されている。これら保護カバー１３，１４は、弾性及び断熱性を有する材料、たとえばウレタンゴムで形成されたものであり、前端側の保護カバー１３は駆動部ケース１１に対して着脱自在とされて、図３に示すアタッチメント６の装着は、保護カバー１３を取り外した状態で行われる。   The main body 1 and the grip 10 are formed by connecting a drive case 11 that covers an impact drive mechanism 3 in which an output shaft 2 protrudes from a tip to a left and right housing 1a, 1b. Protective covers 13 and 14 are attached to the outer surface of the drive unit case 11 that is made of. These protective covers 13 and 14 are formed of a material having elasticity and heat insulation, such as urethane rubber, and the protective cover 13 on the front end side is detachable from the drive unit case 11 and is shown in FIG. The attachment 6 shown is attached with the protective cover 13 removed.

上記アタッチメント６は、締め付け深さの調整用のアジャスターであって、駆動部ケース１１の前端部外周に固定される取付部６０と、この取付部６０に螺合して螺進退で前後に移動するアジャスト部６５で構成されたものである。   The attachment 6 is an adjuster for adjusting the tightening depth, and is attached to the outer periphery of the front end of the drive unit case 11 and is moved forward and backward by screwing into the attachment 60 and screwing back and forth. The adjustment unit 65 is configured.

作業対象箇所の照明用であるライト５は、駆動部ケース１１の外周部でグリップ部１０の上端前方位置に取り付けられているのであるが、透明樹脂製のレンズブロック５０と、このレンズブロック５０に設けられた発光体収納凹部内に配された高輝度発光ダイオード５１とからなる該ライト５は、前記ハウジング１ａ，１ｂとの係合部を備えている取付枠５５を介して取り付けられている。 The light 5 for illuminating the work place is attached to the upper end front position of the grip portion 10 on the outer peripheral portion of the drive unit case 11, and the lens block 50 made of transparent resin and the lens block 50 The light 5 including the high-intensity light-emitting diode 51 disposed in the provided light emitter housing recess is mounted via a mounting frame 55 having an engaging portion with the housings 1a and 1b.

この時、取付枠５５を含むライト５は、図１(b)及び図５から明らかなように、駆動部ケース１１に直接接触することはなく、弾性体で形成されている保護カバー１４がライト５の前端部及び両側部と駆動部ケース１１との間に介在する状態で取り付けられているとともに、保護カバー１４が介在しないライト５の中央部上面と駆動部ケース１１との間には空間が空けられている。   At this time, the light 5 including the mounting frame 55 does not directly contact the drive unit case 11 as is apparent from FIGS. 1B and 5, and the protective cover 14 formed of an elastic body is used as the light. 5 is attached in a state of being interposed between the front end portion and both side portions of the light source 5 and the drive unit case 11, and there is a space between the upper surface of the central portion of the light 5 where the protective cover 14 is not interposed and the drive unit case 11. It is vacant.

トリガースイッチ１６の操作でモータを駆動している時には常時点灯するように構成されている上記ライト５は、インパクト駆動機構３が発生する振動及び熱を本来であれば駆動部ケース１１を介して受けてしまうのであるが、ここでは弾性体からなるとともに断熱性を有している保護カバー１４が駆動部ケース１１との間に介在しているために、ライト５に伝わる振動及び熱が抑制されているものであり、このためにライト５の断線や焼き切れ等が生じにくくなっている。   The light 5, which is configured to always light when the motor is driven by the operation of the trigger switch 16, receives vibration and heat generated by the impact drive mechanism 3 through the drive unit case 11. However, since the protective cover 14 made of an elastic material and having heat insulation is interposed between the drive unit case 11 and the vibration and heat transmitted to the light 5 are suppressed here. For this reason, the light 5 is less likely to break or burn out.

また、断面円形である駆動部ケース１１の外面にライト５を配置する場合、両者の間に隙間が生じて、異物や水がライト内に侵入しやすいのであるが、弾性を有している保護カバー１４が介在するために、防塵防水性の向上も得ることができる。   In addition, when the light 5 is arranged on the outer surface of the drive unit case 11 having a circular cross section, a gap is formed between the two, and foreign matter and water easily enter the light. Since the cover 14 is interposed, an improvement in dustproof and waterproof properties can be obtained.

さらに、保護カバー１４は、使用者が作業に際して手を当てることが多い本体部１の前端部、つまりは駆動部ケース１１外面を覆って振動や熱が使用者に直接伝わることがないようにしている部材であるとともに、電動工具を所持及び搬送する時に滑り止めとして機能しているものであるが、この保護カバー１４の一部をライト５と駆動部ケース１１との間に介在させていることから、ライト５の保護用に別途弾性体を用意する必要がないものとなっている。   Further, the protective cover 14 covers the front end of the main body 1 that is often touched by the user, that is, the outer surface of the drive unit case 11 so that vibration and heat are not directly transmitted to the user. It is a member that functions as an anti-slip when the electric tool is held and transported, and a part of the protective cover 14 is interposed between the light 5 and the drive unit case 11. Therefore, it is not necessary to prepare a separate elastic body for protecting the light 5.
