    Abstract: A power tool has a motor, a clutch device for adjusting torque, a percussion device which has two cam discs, and two adjusting rings for selectively setting four operating modes including a “screwdriving” operating mode, an “impacting” operating mode, a “drilling” operating mode and a “percussion drilling” operating mode. One of the two adjusting rings is a torque adjusting ring operable to select one of the “screwdriving” operating mode, the “impacting” operating mode, and the “drilling” operating mode while the other one of the two adjusting rings is a percussion ring operable to selectively set “percussion drilling” operating mode.

    Abstract: A percussion mechanism for a repetitively hammering hand power tool in the form of a rotary hammer has a striker movable axially forward and backward in a guide barrel and imparting impacts directly and without any intermediate parts to an end section of a tool bit that is insertable into the hand power tool, a device that exerts pressure on the striker, by which the striker is capable of being set into a forward motion in the direction of the tool bit, a blocking element, with which the striker is blockable in its forward motion, and the striking frequency of the striker is adjustable by controlling the blocking time of the blocking element, so that the striking frequency of the striker depends on how long the blocking element blocks the forward motion of the striker.

    Abstract: An improved impact power tool for carving and engraving an article comprises an air delivery system operable to communicate with a pressurized air source; a drive assembly operable to receive air from the pressurized air source via the air delivery system; a hand held device in driven communication with the drive assembly; and a housing for storage of the air delivery system and drive assembly. The tool includes an improved valve design, a throttle bias valve, and an air storage tank housed within the housing, and an improved housing construction. The improved valve design and air storage tank enable greater stroke speeds of a work tool over a wider power range while also improving the crispness and speed of the impact reaction time over the entire range. The throttle bias valve is in communication with an additional exhaust path, such that th bias valve allows improved control of the hand held device and improved operation over a wider range of air pressures.

    Abstract: A hammer drill comprising: a motor; a drive transmission capable of operating in at in at least a rotary mode and a reciprocating mode; a mode change mechanism; a switch which, when closed, provides power to the motor; and a mechanical lock-on mechanism which, when locked mechanically holds the switch closed to maintain the power to the motor. Additionally, the hammer drill includes a first sensor, which indicates the mode of operation of drive transmission; and a second sensor which indicates whether the lock-on mechanism is locked; and a controller which is capable of interfering with the operation of the motor, when the controller detects that the drive transmission is in the rotary mode of operation and the lock-on mechanism has been locked.

    Abstract: A hand tool has a shifting gear unit containing an output drive shaft. The drive shaft can be coupled with different gears by a connecting device so that a coupled gear drives the shaft. The connecting device is displaced by a slide and the slide is, in turn, displaced by a rotatable handle. Drive cams on the handle seat in engagement recesses in the slide. The drive cams and engagement recesses are spaced equal distances apart, so that as the handle is rotated, the drive cams, one after the other, entrain the engagement recesses and move the slide.

    Abstract: A power tool includes a housing in which a drive unit is arranged, and a tool holder for the detachable holding of a tool insert. The tool insert is configured to be driven percussively and/or rotationally. A sensor unit is configured to detect at least one movement variable, and electronics are configured to control or regulate the power tool. The electronics have a percussion detection unit configured to determine a percussion mode based on at least one movement variable and/or a rotation detection unit configured to determine a rotation of the housing. The electronics control the drive unit based on the determined percussion mode and/or the determined rotation of the housing. The electronics have at least two parameter sets for the percussion detection unit and/or at least two parameter sets for the rotation detection unit. The electronics are configured to select one of the at least two parameter sets.
