  • Patent number: 11084160
    Abstract: A hand-held power tool has a tool holder for holding a tool, an electric motor for driving the tool holder, and a handle for holding and guiding the hand-held power tool. A button has a button housing, a pin that can be moved on an actuation axis, and an electric slider which is connected to the pin and which slides on an electric slider track. The button housing is suspended in the handle in such a way that the button housing can be pivoted about a pivot axis perpendicular to the actuation axis.

  • Patent number: 10414036
    Abstract: The control method for a hammer drill (1) provides the following steps. During basic operation, the motor (5) rotates at an operating speed for the drilling operation with chiseling action in order to rotationally drive the tool holder (2) and to drive the hammer mechanism (6) with a nominal striking power. The torque coupling (21) is monitored with the aid of a sensor (26). If a disengagement of the torque coupling (21) occurs, the striking power of the hammer mechanism (6) is reduced to below 10% of the nominal striking power during a disengagement of the torque coupling (21), and the torque coupling (21) is driven. When the disengagement of the torque coupling (21) ends, the striking power of the hammer mechanism (6) is increased to the nominal striking power and the torque coupling (21) is driven at the operating speed for the drilling operation with chiseling action.

    Abstract: A hand-held power tool has a tool holder for holding a tool, an electric motor for driving the tool holder, and a handle for holding and guiding the hand-held power tool. A button has a button housing, a pin that can be moved on an actuation axis, and an electric slider which is connected to the pin and which slides on an electric slider track. The button housing is suspended in the handle in such a way that the button housing can be pivoted about a pivot axis perpendicular to the actuation axis.

  • Publication number: 20180043521
    Abstract: A hand-held power tool (1) includes a tool holder (2) for holding a tool on a working axis (11) and a motor (5) for rotationally driving the tool holder (2) about the working axis (11). The motor (5) is situated in a power-tool housing (16) and a handle (9) is fastened on the power-tool housing (16) for guiding the hand-held power tool (1) during operation. A rotary motion sensor (15) detects a rotary motion of the power-tool housing (16) about the working axis (11). A monitor (19) ascertains a holding force based on an amplitude of the rotary motion in a frequency range between 0.4 Hz and 4 Hz. A safety device (13) reduces a torque output to the tool holder (2) when the detected rotary motion exceeds a limiting value, the limiting value being set as a function of the holding force.
