照明ライト付き電動工具 Electric tool with illumination light
技術分野 Technical field
[0001] 本発明は照明ライトを備えた電動工具の改良技術に関する。 [0001] The present invention relates to a technique for improving a power tool provided with an illumination light.
背景技術 Background art
[0002] 従来から、暗い場所での作業を容易に行うために、作業対象箇所を照らす照明ライ トを備えた電動工具が知られている。この電動工具においては、照明ライトにより工具 の先端付近を効率良く照らす必要性があることから、照明ライトの取付けは、電動ェ 具のインパクト駆動出力を出力する駆動機構を収納する振動が大きく加熱し易い駆 動部ケース外面においてなされている。このため駆動部ケースの振動と加熱から照 明ライトを保護するための対策が採られて 、る。 Conventionally, in order to easily perform work in a dark place, an electric tool including an illumination light that illuminates a work target place is known. In this electric tool, it is necessary to efficiently illuminate the vicinity of the tip of the tool with the illumination light. Therefore, when installing the illumination light, the vibration that houses the drive mechanism that outputs the impact drive output of the electric tool is heated greatly. It is made on the outer surface of the drive unit case. For this reason, measures are taken to protect the illumination light from vibration and heating of the drive case.
[0003] 具体的には、駆動部ケースの外面に対し断熱性を有する弾性部材を介して取り付 けられている。上記弾性部材として駆動部ケースを覆う保護カバーの一部が使用さ れている(例えば、特開 2005— 040934参照)。 [0003] Specifically, it is attached to the outer surface of the drive unit case via an elastic member having heat insulation properties. A part of a protective cover that covers the drive unit case is used as the elastic member (see, for example, JP-A-2005-040934).
[0004] し力しながら、上述の照明ライトの取付けに限定されるところではないが、一般的に 上述のような振動伝達の緩和と熱伝達の遮断を目的とする弾性部材を介在させる部 品等の取付けにおいては、弾性部材の部材の選択にもよるが、弾性部材本来の機 能である弾性力の利用による振動伝達の緩和効果ではそれなりに満足できる結果が 得られるとしても、熱伝達の遮断という視点からは、たとえ断熱性を有する弾性部材 の使用であってもその効果はかなり限られたものであり、必ずしも満足できる結果を 得ることはできない。してみると、上述の部品等の取付けにおいて熱伝達の遮断対策 に視点が置かれる場合には、弾性部材の使用は必ずしも好適な選択であるとは言え ない。 [0004] However, although it is not limited to the above-described installation of the illumination light, in general, a component that interposes an elastic member for the purpose of relaxing vibration transmission and blocking heat transmission as described above Depending on the selection of the elastic member, the vibration transmission mitigation effect by the use of elastic force, which is the original function of the elastic member, may provide a satisfactory result, From the point of view of blocking, even the use of an elastic member with thermal insulation has a very limited effect, and satisfactory results cannot always be obtained. In view of this, the use of an elastic member is not necessarily a suitable choice when the viewpoint is placed on heat transfer interruption measures in the mounting of the above-described components.
[0005] また、弾性部材の介在による取付けにおいて重視されるべきは、弾性部材の長期 使用における熱等の種々の周辺状況力 の影響による損傷や弾性疲労等による劣 化であり、この問題は避けて通ることはできない。弾性部材の劣化は、振動伝達の緩 和効果の著しい低下をもたらすば力りでなぐ熱伝達の遮断効果を低下させるもので
あり、照明ライトの取付けにおいては、取付け部が緩んでガタつきを起こして異音を 発生し、時には照明ライトの破損を招くことにもなる。 [0005] Further, it should be emphasized in the installation by interposing an elastic member that damage due to the influence of various surrounding state forces such as heat in the long-term use of the elastic member, deterioration due to elastic fatigue, and the like should be avoided. Can't pass. The deterioration of the elastic member reduces the heat transfer interruption effect by force if the vibration transfer relaxation effect is significantly reduced. Yes, when mounting an illumination light, the mounting part loosens and rattles and generates an abnormal noise, sometimes resulting in damage to the illumination light.
[0006] 上述の事情力 すると、部品等の取付けにおける弾性部材の介在使用は決して好 適な選択とはいえず、熱伝達の遮断効果向上の視点力 他の照明ライトの取付けに おける好適な改良策の提供が求められている。 [0006] Given the circumstances described above, the use of elastic members in the installation of components and the like is by no means a good choice, and the viewpoint power for improving the heat transfer interruption effect. The preferred improvement in the installation of other lighting lights. There is a need to provide a solution.

In the moving tool, the illumination light is disposed below the drive unit case that houses the rotation drive unit, and a gap is formed between the illumination light and the drive unit case.
[0009] 上記のライト付き電動工具では、照明ライトが回転駆動部を収納する駆動部ケース の下側に配置され、上記照明ライトと駆動部ケースとの間には空隙部が形成されてい るから、駆動部ケース側力 照明ライト側への熱の伝達は上記空隙部により効果的に 遮断される。また、両者間における空隙部は駆動部ケースの振動の伝達も効果的に 遮断する。さらに、空隙部により駆動部ケース外面の放熱効果が高められる。 [0009] In the electric tool with a light, the illumination light is disposed below the drive unit case that houses the rotation drive unit, and a gap is formed between the illumination light and the drive unit case. Drive unit side force Heat transfer to the illumination light side is effectively blocked by the gap. In addition, the gap between the two effectively blocks transmission of vibration in the drive case. Furthermore, the heat radiation effect on the outer surface of the drive unit case is enhanced by the gap.
[0010] また、上記のライト付き電動工具において、上記ハウジングが左右 2つのハウジング 部に縦割り 2分割とされてもよぐ上記照明ライトが一方のハウジング部と他方のハウ ジング部との間に挟持固定されてもよい。 [0010] Further, in the electric tool with a light, the housing light may be divided into two vertically divided into two left and right housing parts, and the illumination light is interposed between one housing part and the other housing part. It may be clamped and fixed.
[0011] 照明ライトが左右のハウジング部の間に挟持固定される場合は、照明ライトの取付 けは強固であり長期使用においても緩むことがない。また、照明ライトの挟持による取 付け作業は比較的容易である。 [0011] When the illumination light is sandwiched and fixed between the left and right housing parts, the illumination light is firmly attached and does not loosen even during long-term use. Also, the installation work by holding the illumination light is relatively easy.
[0012] その他の特徴および効果は、実施例の記載および添付のクレームより明白である。 [0012] Other features and advantages will be apparent from the description of the examples and the appended claims.

As a result, the illumination light 5 is sandwiched and fixed between the housing parts 2a and 2b.
[0024] ところで、上述のように取り付けられたとき、照明ライト 5とハンマケース 13との間に は空隙部 Sが形成されるように構成されている。すなわち、図 6および図 7に示される ように、照明ライト 5のレンズブロック 26の上面部には段部が形成され、中央部分 33 が低くなつている。したがって、両側部 34はハンマケース 13の下面に当接されず、中 央部分 33には空隙部 Sが形成されている。 By the way, when attached as described above, a gap S is formed between the illumination light 5 and the hammer case 13. That is, as shown in FIGS. 6 and 7, a step portion is formed on the upper surface portion of the lens block 26 of the illumination light 5, and the central portion 33 is lowered. Therefore, the side portions 34 are not in contact with the lower surface of the hammer case 13, and the gap portion S is formed in the central portion 33.
[0025] この空隙部 Sには断熱材である空気が満たされているので、ハンマケース 13で発 生した熱の照明ライト 5側への伝達を効果的に遮断することができる。また、この空隙 部 Sは、ハンマケース 13と照明ライト 5間の振動伝達を遮断することができる。さらに、 空隙部 Sはハンマケース 13における熱の発散を良くする。 [0025] Since the space S is filled with air as a heat insulating material, the transfer of heat generated in the hammer case 13 to the illumination light 5 side can be effectively blocked. Further, the gap S can block vibration transmission between the hammer case 13 and the illumination light 5. Further, the gap S improves heat dissipation in the hammer case 13.
[0026] ノ、ウジング 2に対する照明ライト 5の取付けは、 2分割されたノ、ウジング 2の両ノ、ウジ ング部 2a、 2bの照明ライト収容部 18内に収納した状態でレンズブロック 26を挟持し てネジ締め固定することでなされるが、さらに、ハウジング部 2a、 2b側と照明ライト 5側 のそれぞれに形成された係合溝 24と係合凸部 31とが互いに係合するので、長期使 用においても緩むことのない強固な取付け強度が得られる。また、照明ライト 5の挟持 による取付け作業は比較的容易である。 [0026] The illumination light 5 is attached to the louver 2 and the wing 2 by holding the lens block 26 in a state of being housed in the illuminating light housing 18 of the two divided wings 2 and 2 of the wing 2a and 2b. Further, since the engagement grooves 24 and the engagement protrusions 31 formed on the housing portions 2a and 2b and the illumination light 5 side are engaged with each other, it is possible to A strong mounting strength that does not loosen even during use can be obtained. Also, the installation work by holding the illumination light 5 is relatively easy.
[0027] なお、上記照明ライト 5の放熱構造はインパクトドライバに限定されない。電動ドリル 、電動ドライバのような発熱を伴う電動工具にも適用することができる。 [0027] The heat dissipation structure of the illumination light 5 is not limited to the impact driver. It can also be applied to electric tools with heat generation such as electric drills and electric drivers.
[0028] 本発明を詳細にまた特定の実施態様を参照して説明したが、本発明の精神と範囲 を逸脱することなく様々な変更や修正を加えることができることは当業者にとって明ら
かである。 [0028] Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. It is.
[0029] 本出願は、 2006年 3月 30日出願の日本特許出願(特願 2006-095385)に基づくもの であり、その内容はここに参照として取り込まれる。 [0029] This application is based on a Japanese patent application filed on March 30, 2006 (Japanese Patent Application No. 2006-095385), the contents of which are incorporated herein by reference.
