| 20080257934 | NAILING MACHINE - According to an aspect of the present invention, there is provided a nailing machine including: a housing; a motor that is accommodated in the housing; a plunger that plunges a nailing member; and a spring that is expanded or compressed by the motor to store an elastic energy therein and that accelerates the plunger by releasing the elastic energy, wherein a spring constant of the spring at one end of the spring in an expanding/compressing direction is set smaller than that of the spring at a center in the expanding/compressing direction. | 10-23-2008 |
| 20090071998 | DRIVING MACHINE - According to an aspect of the present invention, there is provided a driving device including: a driver bit for striking a fastener loaded in a launching section; a driver for driving the fastener from the launching section by reciprocating the driver bit; triggering means pullable to control the driver; and locking means that locks the pulling operation of the triggering means when being set to a lock position and that releases the locking state when being set to a release position, wherein the locking means includes release means to operate the locking means toward the release position when the triggering means is pulled and returning means to return the locking means toward the lock position when the pulling is released. | 03-19-2009 |
| 20090188766 | FASTENER DRIVING TOOL - A spring-type fastener driving tool includes a plunger having a blade that drives in fasteners, a spring that urges the plunger downwards and is capable of being compressed upwards, a spring compression mechanism unit that includes a drum that causes the plunger to move in a compression direction of the spring based on rotational force of a motor, a reduction mechanism unit, and a one-way clutch than prohibits reverse rotation of the motor. Reverse rotation of the drum due to the urging force of the spring is prevented by providing the one-way clutch between an input side rotating shaft of the reduction mechanism unit and a rotation output shaft of the motor. | 07-30-2009 |
| 20090255972 | ELECTRIC DRIVING MACHINE - An electric driving machine includes a remaining fastener sensor | 10-15-2009 |
| 20100133313 | Nailing Machine - According to an aspect of the present invention, there is provided a nailing machine, including: a drive unit that drives a blade to strike a nail; a blade guide that includes a guide groove to guide the blade; a guide plate that is attached on the blade guide to cover the guide groove; and a magazine that is held with respect to the blade guide and that feeds a nail to the guide groove, wherein the nailing machine further includes a blade fixing unit that limits a movement of the blade when the guide plate is detached. | 06-03-2010 |
| 20100140316 | Fastener Driving Tool - A fastener driving tool providing a prolonged durability and stabilized fastener driving operation. The tool includes a housing | 06-10-2010 |
| 20100237124 | ELECTRIC DRIVING MACHINE - A controller | 09-23-2010 |
