20090039136 | ELECTRIC FASTENER DRIVER - An electric fastener driver having a compact size and simple construction. A driver segment provided with a rack is movably disposed in a housing. A flywheel is driven by a motor. A drive shaft is concentric with and integral with the flywheel. A coil spring is fixed to the drive shaft. A driven rotor is coaxial with the drive shaft and has one end portion serving as a spring seat portion positioned within the coil spring. A pinion is disposed at the driven rotor and is meshedly engaged with the rack. An urging section is disposed within the driven rotor. A ball is movably disposed in a through-hole formed in the driven rotor for urging an end portion of the coil spring by the urging section. A solenoid controls a protruding amount of the ball from the surface of the driven rotor. | 02-12-2009 |
20100102104 | FASTENER DRIVING TOOL - A fastener driving tool includes a housing, a motor, a plunger, a spring, a drum, and one of a cable and a sheet member. The motor is provided in the housing. The plunger is provided in the housing for impacting a fastener in a fastener driving direction. The spring urges the plunger in the fastener driving direction. The drum is rotatably supported in the housing and is rotationally driven by the motor. The one of a cable and a sheet member is capable of being wound over the drum and has one end fixed to the drum and another end acting on the spring for transmitting a driving force of the motor to the spring. The spring is configured to accumulate a resilient energy therein for impacting the fastener by the plunger. The resilient energy of the spring is accumulated by forcible resilient deformation thereof as a result of winding of the one of the cable and the sheet member over the drum rotationally driven by the motor. | 04-29-2010 |

20080237294 | FASTENER DRIVING TOOL HAVING IMPACT BUFFERING MECHANISM - A fastener driving tool includes a housing, a motor, a plunger, a spring, a power transmission mechanism, and an impact buffering portion. The motor is provided in the housing. The plunger is provided in the housing and impacts a fastener in one direction. The spring urges the plunger in the one direction. The power transmission mechanism connects the motor and the plunger for moving the plunger in another direction opposite to the one direction against an urging force of the spring. The impact buffering portion is provided in one of the power transmission mechanism and the plunger. | 10-02-2008 |
