Description

充電式の電気機器Rechargeable electrical equipment
　本発明は、バッテリ装着部を備える電気機器本体と、バッテリ装着部に連結されるバッテリパックを備える充電式の電気機器に関する。 The present invention relates to an electric device main body including a battery mounting portion and a rechargeable electric device including a battery pack connected to the battery mounting portion.
　充電式の電気機器は、例えば特開２０１２－８１５７６号公報に開示されている。電気機器は、図５に示すように充電式のインパクトドライバ１００である。インパクトドライバ１００は、インパクトドライバ本体１０２とバッテリパック１０４と防水カバー１０６を有する。インパクトドライバ本体１０２は、グリップ部１０２ｇの下端にバッテリ装着部１０２ｂを有する。バッテリ装着部１０２ｂにバッテリパック１０４が前方から後方にスライドして連結される。バッテリ装着部１０２ｂの上方部分の全周に段差状のシール面１０２ｓが形成される。 A rechargeable electric device is disclosed in, for example, Japanese Patent Application Laid-Open No. 2012-81576. The electric device is a rechargeable impact driver 100 as shown in FIG. The impact driver 100 includes an impact driver main body 102, a battery pack 104, and a waterproof cover 106. The impact driver main body 102 has a battery mounting portion 102b at the lower end of the grip portion 102g. The battery pack 104 is connected to the battery mounting portion 102b by sliding from the front to the rear. A step-shaped seal surface 102s is formed on the entire periphery of the upper portion of the battery mounting portion 102b.
　防水カバー１０６は、シール面１０２ｓの下側においてバッテリ装着部１０２ｂとバッテリパック１０４を覆う。防水カバー１０６は、袋状であって、上部に開口１０６ｅを備える。防水カバー１０６は、前カバー部１０６ｆと後カバー部１０６ｂと連結機構１０７を有する。前後カバー部１０６ｆ，１０６ｂは、相互に当接する接合面１０６ｘ，１０６ｙを有する。連結機構１０７は、前後カバー部１０６ｆ，１０６ｂを前後方向に押すことで保持する。防水カバー１０６の開口１０６ｅの周縁部がインパクトドライバ本体１０２のシール面１０２ｓに当接される。これにより防水カバー１０６は、インパクトドライバ本体１０２とバッテリパック１０４の連結部をある程度防水し得る。 The waterproof cover 106 covers the battery mounting portion 102b and the battery pack 104 below the seal surface 102s. The waterproof cover 106 has a bag shape and includes an opening 106e in the upper part. The waterproof cover 106 includes a front cover portion 106f, a rear cover portion 106b, and a connecting mechanism 107. The front and rear cover portions 106f and 106b have joint surfaces 106x and 106y that abut against each other. The coupling mechanism 107 holds the front and rear cover portions 106f and 106b by pushing them in the front and rear direction. The peripheral edge portion of the opening 106 e of the waterproof cover 106 is brought into contact with the seal surface 102 s of the impact driver main body 102. Thereby, the waterproof cover 106 can waterproof the connection part of the impact driver main body 102 and the battery pack 104 to some extent.
　防水カバー１０６は、連結機構１０７が前後カバー部１０６ｆ，１０６ｂを前後方向に押すことで袋状に保持される。このため前後カバー部１０６ｆ，１０６ｂの接合面１０６ｘ，１０６ｙ間がある程度シールされる。しかし連結機構１０７は、防水カバー１０６の開口１０６ｅの周縁部をインパクトドライバ本体１０２のシール面１０２ｓに均等に当接させる押圧力を付与しない。このため開口１０６ｅの周縁部とシール面１０２ｓ間のシール性が不十分になり得る。 The waterproof cover 106 is held in a bag shape when the connecting mechanism 107 pushes the front and rear cover portions 106f and 106b in the front and rear direction. For this reason, the space between the joint surfaces 106x and 106y of the front and rear cover portions 106f and 106b is sealed to some extent. However, the connecting mechanism 107 does not apply a pressing force that evenly contacts the peripheral edge of the opening 106 e of the waterproof cover 106 with the seal surface 102 s of the impact driver main body 102. For this reason, the sealing performance between the peripheral edge portion of the opening 106e and the sealing surface 102s may be insufficient.
　そのため電気機器本体と防水カバー間のシール性の高い充電式の電気機器が従来必要とされている。 Therefore, a rechargeable electric device having a high sealing property between the electric device main body and the waterproof cover is conventionally required.
　１つの特徴によると充電式の電気機器は、電気機器本体、バッテリパック、防水カバー、カバー受け部、防水カバー保持機構を有する。バッテリパックは、電気機器本体のバッテリ装着部に接続される。防水カバーは、有底筒形でバッテリパックとバッテリ装着部を覆う。カバー受け部は、防水カバーの開口周縁の全周と水密に当接するように電気機器本体に形成される。防水カバー保持機構は、防水カバーの開口周縁をカバー受け部に当接した状態に保持する。防水カバーの開口周縁は、カバー受け部に直接的に当接しても良いし、あるいはシール材等を介して当接しても良い。 According to one characteristic, the rechargeable electric device has an electric device main body, a battery pack, a waterproof cover, a cover receiving portion, and a waterproof cover holding mechanism. The battery pack is connected to a battery mounting portion of the electric device main body. The waterproof cover has a bottomed cylindrical shape and covers the battery pack and the battery mounting portion. The cover receiving portion is formed on the main body of the electric device so as to be in watertight contact with the entire periphery of the opening peripheral edge of the waterproof cover. The waterproof cover holding mechanism holds the peripheral edge of the waterproof cover in contact with the cover receiving portion. The opening peripheral edge of the waterproof cover may be in direct contact with the cover receiving portion, or may be in contact with a sealing material or the like.
　したがって防水カバーの開口周縁と電気機器本体のカバー受け部間のシール性が確保される。さらに防水カバーは、単一の部材で、従来のように複数の部材を組み合わせて構成されるものではない。そのため防水カバー本体のシール性も高くなる。 Therefore, the sealing property between the opening peripheral edge of the waterproof cover and the cover receiving portion of the electric device main body is ensured. Further, the waterproof cover is a single member and is not configured by combining a plurality of members as in the conventional case. Therefore, the sealing performance of the waterproof cover body is also improved.
　他の特徴によると防水カバー保持機構は、防水カバーの開口周縁をカバー受け部に周方向に均一な力で押圧するように構成されても良い。したがって防水カバーの周方向においてシール性能がばらつくことがなくなる、あるいは少なくなる。 According to another feature, the waterproof cover holding mechanism may be configured to press the peripheral edge of the waterproof cover against the cover receiving portion with a uniform force in the circumferential direction. Accordingly, the sealing performance does not vary or decreases in the circumferential direction of the waterproof cover.
　他の特徴によると電気機器は、カバー受け部と防水カバーの開口周縁を水密に保持するようにカバー受け部と防水カバーの開口周縁に挟持される防浸部材を有しても良い。したがって防浸部材がない場合と比較してシール性能が高い。 According to another feature, the electrical device may include an immersion member that is sandwiched between the cover receiving portion and the opening periphery of the waterproof cover so as to keep the opening periphery of the cover receiving portion and the waterproof cover watertight. Therefore, the sealing performance is high as compared with the case where there is no immersion member.
　他の特徴によるとカバー受け部あるいは防水カバーの開口周縁には、防浸部材が設置される凹部が形成され得る。したがって防浸部材は、カバー受け部あるいは防水カバーの開口周縁に保持され得る。これにより防水カバーを電気機器本体に取付ける際または防水カバーを電気機器本体から取外す際に防浸部材が脱落することが防止され得る。 According to another feature, a recess in which the water-proof member is installed may be formed at the periphery of the opening of the cover receiving portion or the waterproof cover. Therefore, the immersion preventing member can be held on the opening periphery of the cover receiving portion or the waterproof cover. Thereby, when the waterproof cover is attached to the electric device main body or when the waterproof cover is removed from the electric device main body, the immersion member can be prevented from falling off.
　他の特徴によると防水カバー保持機構は、防水カバーが被せられる電気機器本体の外周面に形成された雄ネジと、防水カバーの内周面に形成されて雄ネジと螺合される雌ネジを有し得る。したがって防水カバーの開口周縁が電気機器本体のカバー受け部に対し周方向に均一な力で押圧され得る。また電気機器本体と防水カバーを確実に連結し得る。 According to another feature, the waterproof cover holding mechanism includes a male screw formed on the outer peripheral surface of the electric device body to be covered with the waterproof cover and a female screw formed on the inner peripheral surface of the waterproof cover and screwed with the male screw. Can have.

　図２－４に示すように防水カバー４０は、開口４５の周縁にリング先端面４５ｆとテーパ面４５ｔが設けられる。リング先端面４５ｆは、ドライバ本体２０の段差部２９ｄに当接される。テーパ面４５ｔは、リング先端面４５ｆの半径方向内側にリング先端面４５ｆと同軸に形成される。テーパ面４５ｔは、オーリング２９ｒを軸方向へ押し、かつオーリング２９ｒを半径方向外側から押す。 2-4, the waterproof cover 40 is provided with a ring front end surface 45f and a tapered surface 45t on the periphery of the opening 45. The ring front end surface 45f is in contact with the stepped portion 29d of the driver main body 20. The tapered surface 45t is formed coaxially with the ring front end surface 45f on the radially inner side of the ring front end surface 45f. The tapered surface 45t pushes the O-ring 29r in the axial direction and pushes the O-ring 29r from the outside in the radial direction.
　図１，２に示すようにバッテリパック３０をドライバ本体２０に連結し、バッテリ装着部２８の雄ネジ２８ｍに防水カバー４０の雌ネジ４３を螺合させる。これにより防水カバー４０がバッテリ装着部２８とバッテリパック３０を覆う。防水カバー４０のリング先端面４５ｆが段差部２９ｄに全周に亘って当接し、テーパ面４５ｔがオーリング２９ｒを押圧する。これにより防水カバー４０の開口４５の周縁とドライバ本体２０のカバー受け部２９のシール性が確保される。 1 and 2, the battery pack 30 is connected to the driver body 20, and the female screw 43 of the waterproof cover 40 is screwed into the male screw 28m of the battery mounting portion 28. Thereby, the waterproof cover 40 covers the battery mounting portion 28 and the battery pack 30. The ring front end surface 45f of the waterproof cover 40 contacts the step portion 29d over the entire circumference, and the tapered surface 45t presses the O-ring 29r. Thereby, the sealing performance of the peripheral edge of the opening 45 of the waterproof cover 40 and the cover receiving portion 29 of the driver main body 20 is ensured.
　上述するようにバッテリ装着部２８とバッテリパック３０が有底筒形の防水カバー４０に覆われる。防水カバー保持機構（バッテリ装着部２８の雄ネジ２８ｍと防水カバー４０の雌ネジ４３）は、防水カバー４０のリング先端面４５ｆとテーパ面４５ｔ（開口周縁）を全周に亘ってドライバ本体２０のカバー受け部２９に水密に当接させる。 As described above, the battery mounting portion 28 and the battery pack 30 are covered with the bottomed cylindrical waterproof cover 40. The waterproof cover holding mechanism (the male screw 28m of the battery mounting portion 28 and the female screw 43 of the waterproof cover 40) has a ring front end surface 45f and a tapered surface 45t (opening peripheral edge) of the waterproof cover 40 over the entire circumference. The cover receiving portion 29 is brought into watertight contact.
　このため防水カバー４０とドライバ本体２０間のシール性が確保される。防水カバー４０は、単一の部材である。一方従来のカバーは、複数の部材を組み合わせて構成される。そのため防水カバー４０は、従来の構造に比べてシール性に優れ得る。 Therefore, the sealing property between the waterproof cover 40 and the driver main body 20 is ensured. The waterproof cover 40 is a single member. On the other hand, the conventional cover is configured by combining a plurality of members. Therefore, the waterproof cover 40 can be excellent in sealing performance as compared with the conventional structure.
　図１，２に示すように防水カバー保持機構は、バッテリ装着部２８の雄ネジ２８ｍと防水カバー４０の雌ネジ４３を有する。そのため防水カバー保持機構は、防水カバー４０の開口周縁をドライバ本体２０のカバー受け部２９に周方向に均一な力で押し付け得る。また防水カバー保持機構は、ドライバ本体２０と防水カバー４０を確実に連結し得る。 1 and 2, the waterproof cover holding mechanism has a male screw 28 m of the battery mounting portion 28 and a female screw 43 of the waterproof cover 40. Therefore, the waterproof cover holding mechanism can press the opening peripheral edge of the waterproof cover 40 against the cover receiving portion 29 of the driver main body 20 with a uniform force in the circumferential direction. Further, the waterproof cover holding mechanism can reliably connect the driver main body 20 and the waterproof cover 40.
　図４に示すようにオーリング（防浸部材）２９ｒは、リング溝部２９ｋに保持される。そのため防水カバー４０をドライバ本体２０に取付ける際あるいは防水カバー４０をドライバ本体２０から取外す際、オーリング２９ｒがカバー受け部２９から脱落することが防止され得る。 As shown in FIG. 4, the O-ring (anti-immersion member) 29r is held in the ring groove 29k. Therefore, when attaching the waterproof cover 40 to the driver main body 20 or when removing the waterproof cover 40 from the driver main body 20, it is possible to prevent the O-ring 29 r from falling off from the cover receiving portion 29.
