The handle part 3 is detachably attached to a terminal part of a rechargeable battery pack 30 serving as a power source for the electric tool 1. Specifically, the handle portion 3 has an opening at a terminal portion (an end portion on the side opposite to the rotation shaft 10 in the axial direction of the handle portion 3), and the battery cell 30a of the battery pack 30 is inserted into the handle portion 3 from the opening. The battery pack 30 can be attached to the handle portion 3 by inserting the battery pack 30 into the handle portion 3 and locking the battery pack 30 to the end portion of the handle portion 3 by a known latch mechanism. Further, the battery pack 30 can be removed from the handle portion 3 by releasing the latch by the latch mechanism by the latch operation portion 31. In the handle portion 3, a switch mechanism 6 that controls energization and stoppage from the battery pack 30 to the motor 4 is provided. The user can operate energization and stop (drive and stop of the motor 4) of the motor 4 by operating (pulling) the switch operation unit (trigger) 7 provided in the handle unit 3.
フック5は、電動工具1を不使用時に掛止する(吊り下げる)ための好ましくは金属製の部材であり、ハンドル部3の末端部に設けられる。フック5の回動支点部5aは、ハンドル部3に設けられた貫通穴3aに挿入される。貫通穴3aは、ハンドル部3の軸周り方向に関する位置がトリガ7と同じである。すなわち、貫通孔3aは、ハンドル部3においてトリガ7と同じ側であって、ガンタイプの形態とした場合には図1及び図2に示すように取付穴25a側(前側)に設けられる。フック5は、図2、図4及び図6に示す角度θの範囲でハンドル部3に対して回動可能である。すなわち、フック5は、図2に示す使用位置と退避位置との間で回動可能である。フック5は、退避位置において、ハンドル部3の末端側(ハンドル部3の末端部と電池パック30)を、ハンドル部3の軸周り方向に囲む。
The hook 5 is preferably a metal member for hooking (suspending) the electric power tool 1 when not in use, and is provided at the end of the handle portion 3. The pivot fulcrum part 5 a of the hook 5 is inserted into a through hole 3 a provided in the handle part 3. The position of the through hole 3 a in the direction around the axis of the handle portion 3 is the same as that of the trigger 7. That is, the through-hole 3a is provided on the same side as the trigger 7 in the handle portion 3 and on the mounting hole 25a side (front side) as shown in FIGS. The hook 5 is rotatable with respect to the handle portion 3 within the range of the angle θ shown in FIGS. 2, 4 and 6. That is, the hook 5 is rotatable between the use position and the retracted position shown in FIG. The hook 5 surrounds the end side of the handle portion 3 (the end portion of the handle portion 3 and the battery pack 30) in the direction around the axis of the handle portion 3 in the retracted position.
図10に示すように、フック5の自由端部5d(ハンドル部3の中心軸を挟んで回動支点部5aと反対側の端部)は、電池パック30の角部と係合し、退避位置から使用位置に向けての回動が規制される。すなわち、ハンドル部3の貫通穴3aと電池パック30の前記角部との間の距離は、フック5の回動支点部5aと自由端部5dとの間の距離よりも僅かに大きく、フック5の自由端部5dは電池パック30の角部を跨ぐところで引っ掛かるようになっている。ユーザは、フック5の自由端部5dに回動支点部5aから離れるように軽く力を加えることにより、回動支点部5aと自由端部5dとの間の距離を広げ、フック5を電池パック30の角部を跨いで回動させることができる。
As shown in FIG. 10, the free end 5d of hook 5 (the end opposite to the rotation fulcrum 5a across the central axis of the handle 3) engages with the corner of the battery pack 30 and retracts. The rotation from the position toward the use position is restricted. That is, the distance between the through hole 3a of the handle portion 3 and the corner portion of the battery pack 30 is slightly larger than the distance between the rotation fulcrum portion 5a of the hook 5 and the free end portion 5d. The free end 5d of the battery pack is caught at the corner of the battery pack 30. The user applies a light force to the free end portion 5d of the hook 5 so as to move away from the rotation fulcrum portion 5a, thereby widening the distance between the rotation fulcrum portion 5a and the free end portion 5d. It can be rotated across 30 corners.
図7に示すように、退避位置にあるフック5は、回動支点部5aから延びてハンドル部3の軸と垂直な平面内でハンドル部3の末端部及び電池パック30の周りを周回する平面周回部5bと、平面周回部5bからハンドル部3の末端側に傾斜して自由端部5dに向かって延びる傾斜部5cと、を含む。すなわち、フック5は回動支点部5a、平面周回部5b、傾斜部5c、自由端部5d、傾斜部5c、平面周回部5b及び回動支点部5aによってリング状(ループ状)に形成される。なお、一対の回転支点部5a間は互いに離れているため図8に示すようにC字のリング状(ループ状)に形成される。また、平面周回部5b、傾斜部5c及び自由端部5dは一対の回動支点部5aを接続する接続部を構成する。フック5は、傾斜部5cがあることにより、回動支点部5aの位置と、自由端部5dの位置とが、ハンドル部3の軸方向にずれている。平面周回部5bと傾斜部5cは、電池パック30のラッチ操作部31と重ならない位置で相互に接続されている。すなわち、フック5は、退避位置において、電池パック30のラッチ操作部31と重ならないように、ハンドル部3の軸垂直方向から見て曲がっている。
As shown in FIG. 7, the hook 5 in the retracted position extends from the rotation fulcrum portion 5 a and circulates around the end portion of the handle portion 3 and the battery pack 30 in a plane perpendicular to the axis of the handle portion 3. It includes a circumferential portion 5b and an inclined portion 5c that is inclined from the planar circumferential portion 5b to the distal end side of the handle portion 3 and extends toward the free end portion 5d. That is, the hook 5 is formed in a ring shape (loop shape) by the rotation fulcrum part 5a, the plane circumference part 5b, the inclined part 5c, the free end part 5d, the inclination part 5c, the plane circumference part 5b, and the rotation fulcrum part 5a. . Since the pair of rotation fulcrum portions 5a are separated from each other, they are formed in a C-shaped ring shape (loop shape) as shown in FIG. Moreover, the plane periphery part 5b, the inclination part 5c, and the free end part 5d comprise the connection part which connects a pair of rotation fulcrum part 5a. Since the hook 5 has the inclined portion 5 c, the position of the rotation fulcrum portion 5 a and the position of the free end portion 5 d are shifted in the axial direction of the handle portion 3. The planar rotating portion 5b and the inclined portion 5c are connected to each other at a position that does not overlap the latch operation portion 31 of the battery pack 30. That is, the hook 5 is bent when viewed from the direction perpendicular to the axis of the handle portion 3 so as not to overlap the latch operation portion 31 of the battery pack 30 at the retracted position.
図2に示すように電動工具1をガンタイプ形態で使用する際は、フック5が角度θの範囲内のいずれの位置にあっても、フック5がユーザの手9に接触することない。図4に示すように、電動工具1をストレート形態で使用し、水平方向に推力を加える際も、フック5が角度θの範囲内のいずれの位置にあっても、フック5がユーザの手9に接触することない。図6に示すように、電動工具1をストレート形態で使用し、鉛直方向(図中下方)に推力を加える際も、フック5が角度θの範囲内のいずれの位置にあっても、フック5がユーザの手9に接触することない。いずれの場合も、フック5が使用位置にあると、狭所での作業で構造物等に接触する等で操作性が損なわれるのであれば、フック5を図2等に示す退避位置に回動させればよい。
As shown in FIG. 2, when the electric tool 1 is used in a gun type configuration, the hook 5 does not contact the user's hand 9 regardless of the position of the hook 5 within the range of the angle θ. As shown in FIG. 4, when the electric tool 1 is used in a straight form and the thrust is applied in the horizontal direction, the hook 5 remains in the user's hand 9 regardless of the position of the hook 5 in the range of the angle θ. Never touch. As shown in FIG. 6, even when the electric tool 1 is used in a straight configuration and thrust is applied in the vertical direction (downward in the figure), the hook 5 can be placed at any position within the range of the angle θ. Does not touch the user's hand 9. In any case, when the hook 5 is in the use position, if the operability is impaired due to contact with a structure or the like by working in a narrow place, the hook 5 is rotated to the retracted position shown in FIG. You can do it.
フック5をハンドル部3から取り外す場合には、金属のバネ性を利用して図8の状態から一対の回動支点部5aを互いに離間する方向に押し広げ(図9のF方向に力を加え)、図9に示すように一対の回動支点部5aをハンドル部3の貫通穴3aから外せばよい。フック5をハンドル部3に取り付ける場合には、一対の回動支点部5aを押し広げて図9に示すように貫通穴3aの両側にセットし、図8に示すように一対の回動支点部5aを貫通穴3a内に挿入すればよい。
When the hook 5 is removed from the handle portion 3, the pair of rotating fulcrum portions 5a are pushed away from the state shown in FIG. 8 using the metal spring property (force is applied in the F direction in FIG. 9). 9), the pair of rotation fulcrum parts 5a may be removed from the through holes 3a of the handle part 3 as shown in FIG. When the hook 5 is attached to the handle portion 3, the pair of rotating fulcrum portions 5a are spread and set on both sides of the through hole 3a as shown in FIG. 9, and the pair of rotating fulcrum portions as shown in FIG. What is necessary is just to insert 5a in the through-hole 3a.
