- this mounting portion is utilized to mount the battery protector 121.
- This mounting portion is a feature that corresponds to the "mounting portion" according to the present invention.
- an engagement piece 123d is integrally formed on the upper frame portion of the rigid element 123a of each of the side frames 123 and extends horizontally inward from the rear region (in the longitudinal direction) of the upper frame portion. Further, a mounting hole 123e is formed slightly below the engagement piece 123d and extends through the upper frame portion in the lateral direction. The right and left engagement pieces 123d are inserted into the associated engagement grooves 109a of the battery holder 109 and thereby serve as a means for positioning and temporarily fixing the battery protector 121 to the battery holder 109 when the battery protector 121 is mounted to the battery holder 109.
- the battery protector 121 having the above-described construction is mounted to the battery holder 109 in the following procedures. First, the side frames 123 are rotated on the connecting pin 127 in a direction that increases the distance between the side frames 123 on the rear side. In this state, the side frames 123 are then positioned to face the sides 111b of the battery pack 111. Thereafter, the side frames 123 are rotated back on the connecting pin 127 in a direction that decreases the distance between the side frames 123 on the rear side. In this manner, the engagement pieces 123d are fitted into the associated engagement grooves 109a of the battery holder 109. Thus, the battery protector 121 is positioned and temporarily fixed to the battery holder 109.
- the mounting screws 129 are passed through the mounting holes 123e and driven into the screw holes of the protector mounting portions 109b.
- the battery protector 121 can be mounted to the battery holder 109. Further, the battery protector 121 can be removed from the battery holder 109 by reversing the above-described mounting procedure.
- FIGS. 3 and 4 show the battery protector 121 attached to the battery holder 109.
- the inner faces of the side frames 123 of the battery protector 121 are located along the associated sides 111b of the battery pack 111 with a clearance therebetween.
- the upper face of the connecting plate 125 is located under a bottom 111d of the battery pack 111 with a clearance therebetween.
- the front end portions of the side frames 123 protrude a predetermined distance forward from the front 111a of the battery pack 111, and the rear end portions of the side frames 123 protrude a predetermined distance rearward from a back 111c of the battery pack 111. Further, the lower end portions of the side frames 123 protrude a predetermined distance downward from the bottom 111d of the battery pack 111.
- a front portion of the protector 121 which faces the front 111 a of the battery pack 111 on which the lock release lever 117 is mounted and a rear portion of the protector 121 which faces the back 111c of the battery pack 111 are open.
- the user's fingers holding the battery pack 111 can pass through the open front and rear portions together with the battery pack 111 when the battery pack 111 is attached to and removed from the battery holder 109.
- the open front portion and the open rear portion are designated by symbols "FO” and "RO", respectively.
- the user when removing the battery pack 111 from the battery holder 109 in order, for example, to charge the battery pack 111, the user insert the thumb into the open front portion FO and the other fingers into the open rear portion RO. Then, the lock release lever 117 is pressed with the thumb in order to release the lock of the battery pack 111 by the lock device with respect to the battery holder 109. In this state, the battery pack 111 is slid forward while holding the back 111c ofthe battery pack 111 with the fingers other than the thumb. Thus, the battery pack 111 can be removed from the battery holder 109 via the open front portion FO of the battery protector 121 without interfering with the battery protector 121.
- the lock device When the battery pack 111 is in a position a predetermined distance away from its mounting position, the lock device is kept in the lock-released state even if the lock release lever 117 is released. Therefore, it is not necessary to keep pressing the lock release lever 117 until the battery pack is completely removed. Thus, the user is allowed to once release the fingers from the battery pack 111 and then hold it again in the process of its removal.
- the fingers other than the thumb are initially placed to cross the connecting plate 125.
- the fingers can be released from the battery pack 111 and then held again in the process of its removal. Further, the battery pack 111 can be attached to the battery holder 109 by reversing the above-described removing procedure.
- the battery protector 121 can be left attached to the battery holder 109 while the battery pack 111 is attached to and removed from the battery holder 109.
- the open front and rear portions FO, RO of the battery protector 121 are features that correspond to the "open region" according to the present invention.
- the vibration driver drill 100 is provided with the battery protector 121 for protecting the battery pack 111.
- the inner faces of the right and left side frames 123 of the battery protector 121 are located along the associated sides 111b of the battery pack 111 with a clearance of certain distances. Further, the front, rear and lower end portions of the side frames 123 protrude outward from the front 111a, the back 111c and the bottom 111d of the battery pack 111, respectively.
- the vibration driver drill 100 is dropped on the ground during use or carry, either one or both of the frames 123 hit the ground, so that not only the sides 111 b but also the front 111a, the back 111c and the bottom 111d of the battery protector 121 can be protected from directly hitting the ground.
- the same protective effect can be obtained as a construction in which the entire outside surface of the battery pack 111 is covered.
- the side frames 123 are spaced apart from the associated sides 111b of the battery pack 111. Therefore, an external force (impact force) upon the side frames 123 can be prevented from being transmitted to the battery pack 111.
- the battery protector 121 can effectively protect the battery pack 111 against impact when the vibration driver drill 100 is dropped or struck against something during use or carry.
- the rigid element 123a made of sheet metal and the elastic element 123b covering the rigid element 123a form each of the side frames 123. Therefore, the side frames 123 are capable of cushioning the impact of hitting the ground or any other object while maintaining a predetermined rigidity. Thus, the protection performance for protecting the battery pack 111 can be further improved.
- the battery protector 121 can be removably attached to the battery holder 109 formed on the tool body side. Therefore, in contrast to the construction in which a cushioning element is directly provided on the battery pack 111, if the battery protector 121 is broken, only the broken battery protector 121 can be replaced with a new one, and thus the whole battery pack itself need not be replaced with a new one.
- the engagement groove 109a and the mounting portion 109b of the battery holder 109 form a mounting portion for mounting attachments, namely a hook or a bit holder.
- the existing mounting portion is utilized to mount the battery protector 121.
- each of the side frames 123 of the battery protector 121 is formed with the engagement piece 123d that can be engaged in the engagement groove 109a and the mounting hole 123e for the mounting screw 129, so that the battery protector 121 can be attached to the battery holder 109.
- the mounting structure for the battery protector 121 can be efficiently provided.
- either the attachment or the battery protector 121 can be selectively mounted to the attachment mounting portion.
- the side frames 123 can be rotated horizontally on the connecting pin 127, so that the distance between the side frames 123 on the side of the engagement pieces 123d can be increased or decreased.
- the engagement pieces 123d can be easily engaged in or disengaged from the engagement grooves 109a when the battery protector 121 is attached to or removed from the battery holder 109. Therefore, this construction is effective in work simplification of mounting and removing the battery protector 121.
- the battery protector 121 is generally U-sbaped as viewed from the front, including a pair ofright and left side frames 123 extending in the longitudinal direction ofthe body 101 and a connecting plate 125 that connects the side frames 123 on the bottom side.
- the battery protector 121 is configured to have open front and back located in the direction of attachment and removal of the battery pack 111. With this configuration, the battery protector 121 can be left attached to the battery holder 109 while the battery pack 111 is attached to and removed from the battery holder 109. Therefore, ease of operation of mounting and removing the battery pack 111 can be improved.
- each of the right and left side frames 123 is formed by only the rigid element 123a of the metal sheet.
- the connecting plate 125 is integrally formed with the side frames 123 and extends between the lower frame portions of the side frames 123.
- the side frames 123 are connected to each other by the connecting plate 125.
- the engagement piece 123d and the mounting hole 123e for mounting the battery protector 121 to the battery holder 109 are formed in the upper frame portion of each of the side frames 123.
- the engagement pieces 123d are engaged in the associated engagement groove 109a which are formed in the battery holder 109 on the lower end ofthe handgrip 107, and the mounting screws 129 are inserted through the mounting holes 123e and driven into the screw holes of the mounting portions 109b.
- the distance between the upper frame portions of the side frames 123 can be increased such that the upper frame portions are moved away from each other by utilizing the elastic deformation of the connecting plate 125. Therefore, the engagement pieces 123d can be inserted into and removed from the associated engagement groove 109a without any trouble.
- the battery protector 121 is positioned and temporarily fixed to the battery holder 109 by the engagement pieces 123d, so that the screw-tightening operation by using the mounting screws 129 can be facilitated. Further, the battery protector 121 is manufactured from only the rigid element 123a or metal sheet. This is effective in realizing simplification of the structure and weigh reduction while ensuring a predetermined rigidity, and also in reduction of the manufacturing costs.
- the power tool is describe as being of the slide type in which the battery pack 111 is mounted to and removed from the battery holder 109 by moving in a direction that intersects with the extending direction of the handgrip 107.
- this invention can also be applied to a power tool of an insertion type in which the battery pack is mounted and removed by moving the battery pack 111 in the extending direction of the handgrip 107.
- the battery protector 121 for protecting the insertion-type battery pack has an open side that faces one side (for example, the front) of the outer surface of the battery pack 111 on which at least the lock release lever 117 of the locking device that locks the battery pack 111 to the battery holder 109 is provided.
- the battery protector 121 also has another open side which faces the bottom of the battery pack 111 in the direction of removal of the battery pack 111.
- frame portions are provided as a battery pack protection area.
- the battery protector 121 can be left attached to the battery holder 109 while the user operates the lock release lever 117 in order to allow removal of the battery pack and then withdraws the battery pack 111 while holding the front and the back of the battery pack 111 by the fingers inserted through the open sides.
- the battery pack 111 can also be mounted while the battery protector 121 is left attached to the battery holder 109.
- the user operates the lock release lever 117 with the finger to allow the battery pack 111 to be removed, and while keeping this state, the user holds the battery pack 111 and removes the battery pack 111 from the battery holder 109.
- the fingers holding the battery pack 111 are placed to cross the connecting plate 125.
- the battery protector 121 may be configured such that the fingers holding the battery pack 111 are not placed to cross the connecting plate 125, or specifically such that the fingers can be passed through the open area without interference (without need of holding the battery pack 111 again after once released).
- the construction in which the side frames 123 rotate horizontally via the connecting pins 127 may be changed into the construction as described in the second embodiment in which the side frames 123 are integrally formed with the connecting plate 125.
- the mounting structure for mounting the battery protector 121 to the battery holder 109 may be changed to a different one from that shown in the drawings.
- the side frames 123 may be changed to a construction not having an opening in the center, such as a construction in which a flat plate forms the side frames 123 and entirely covers the side surfaces of the battery pack 111.
