| 20110025207 | ELECTRIC POWER TOOL - An electric power tool can include a main body, which rotates a motor with a pull operation of the switch lever and actuates a head tool by a rotative force of the motor, and an auxiliary tool configured for attaching and detaching to and from the electric power tool main body. In the main body, an actuating part actuated with the pull operation of the switch lever is provided. The auxiliary tool includes a detecting part, which noncontactly detects an actuation of the actuating part, and an electric circuit section for actuating electric devices, provided in the auxiliary part, by a detecting actuation of the detecting part. | 02-03-2011 |
| 20110030986 | POWER TOOLS - A plurality of components of a power tool are coupled to each other to form a component assembly. Positioning members are disposed within a housing body and resiliently support the component assembly from opposite sides in an axial direction. | 02-10-2011 |
| 20110031098 | SWITCH DEVICES - A switch device includes a switch body and an operation member. The switch body includes a case and a rotary shaft rotatably supported by the case and extending from one end of the case in an axial direction. The operation member is joined to the rotary shaft. The case has a cylindrical outer surface and the operation member has a cylindrical inner surface disposed coaxial with the cylindrical outer surface of the case. A support member is disposed at one of the cylindrical outer surface of the case and the cylindrical inner surface of the operation member and has an edge portion extending linearly along a circumferential direction of the one of the cylindrical outer surface and the cylindrical inner surface, so that the edge portion can slidably contact the other of the cylindrical outer surface of the case and the cylindrical inner surface of the operation member. | 02-10-2011 |
| 20110108300 | HOOK FOR ELECTRIC POWER TOOL AND RECHARGEABLE ELECTRIC POWER TOOL EQUIPPED WITH THE HOOK - A hook for an electric power tool is engageable with a carabiner comprising a hook end portion, and a gate member capable of opening the hook end portion. The hook includes: a base portion attached to a housing of a rechargeable electric power tool; an engagement portion positioned outside the base portion and having a first through-hole; a folded-back portion connecting the base portion and the engagement portion and having a second through-hole; and an outer abutment portion formed between the first and second through-holes and configured to cause the gate member to be bent inwardly when the gate member is pressed against the outer abutment portion. The outer abutment portion is engaged with the carabiner by inserting the hook end portion into the first and second through-holes, while the gate member is pressed against the outer abutment portion to open the hook end portion. | 05-12-2011 |
| 20110113587 | DUST COLLECTOR - In a dust collector, a main body includes a motor and a rotary fan. The rotary fan is to be driven by the motor to suck air from outside through an intake port provided at the main body. A receptacle unit configured to allow a battery pack to be attached thereto and an exhaust port configured to allow a dust bag to be detachably attached thereto are provided at the main body. A handle capable of being grasped and a belt fastening part configured to allow a belt to be fastened thereto are also provided at the main body. At an underside of the main body, a supporting surface is provided which is configured to allow the dust collector with the dust bag and the battery pack attached to the exhaust port and to the receptacle unit respectively to be placed thereon. | 05-19-2011 |
| 20110139479 | HOOK FOR ELECTRIC POWER TOOLS AND ELECTRIC POWER TOOL EQUIPPED WITH THE HOOK - A hook for electric power tools is disclosed. The hook is used with an electric power tool comprising a handle and a battery pack detachably mounted to a lower end portion of the handle. The hook is designed to be attached to the electric power tool in the proximity of the lower end portion of the handle and includes a ring-shaped slip-off preventing portion having an opening into which, when the battery pack is not attached to the handle, the handle can be inserted into the opening of the slip-off preventing portion, and when the battery pack is attached to the handle, the slip-off preventing portion can be prevented from being pulled out from the handle by the battery pack attached to the handle. | 06-16-2011 |
| 20110180289 | IMPACT TOOL - The cover is provided with engaging pieces that engage with a recessed groove provided on the outer peripheral surface of a hammer case and hold the cover on the hammer case to prevent the cover from being detached. The cover is also provided with bumper receiving portions extending from the front end of the cover and allowing the bumper to be externally attached to the cover, and engaging claws formed on the bumper receiving portions and engaging with engaged recessed portions formed on the inner peripheral surface of the bumper for holding the bumper to prevent the bumper from being detached from the cover. The cover with the bumper attached to the bumper receiving portions is provided to the hammer case. | 07-28-2011 |
| 20120000683 | IMPACT TOOL - To ensure that a hammer can retract by a sufficient amount without interfering with a washer receiving a rear end of a coil spring, there is disclosed an impact driver having a washer receiving a rear end of a coil spring biasing a hammer of an impact mechanism to an advanced position. The washer is annular with an inner diameter larger than an inner diameter of an annular groove disposed on a rear surface of the hammer, and includes a frontward extended portion disposed at an inner circumference of the washer. Between a carrier portion of the spindle and the washer, there is disposed a positioner that positions the washer coaxially with the spindle. | 01-05-2012 |
