  • Patent number: 10562164
    Abstract: The invention relates to a drive-in device, comprising a hand-held housing having a piston element received therein for transmitting energy onto a fastening element to be driven in, an exchangeable propellant charge, a combustion chamber, arranged between the propellant charge and the piston element and extending about a center axis (A), and a control element by means of which a starting position of the piston element can be set to be modified in order to modify the energy transmitted by the propellant charge onto the piston element, the control element having an operating element that can be pivoted about the center axis (A).
    Type: Grant
    Filed: December 16, 2014
    Date of Patent: February 18, 2020

  • Patent number: 10160109
    Abstract: The invention relates to a driving device, comprising a hand-held housing having an energy transmission element accommodated therein for transmitting energy to a fastening element to be driven in, an exchangeable propellant charge and a combustion chamber arranged between the propellant charge and the energy transmission element, said combustion chamber extending about a central axis, wherein the combustion chamber is subdivided by means of a dividing member having a number of interruptions into a first subchamber adjoining the propellant charge and at least one second subchamber adjoining the energy transmission element, wherein an ejection region, enclosing a central axis, for the propellant charge is provided in the first subchamber, said ejection region extending between the propellant charge and a central region of the dividing member, wherein the ejection region is bounded at the central region of the dividing member by a closed surface of the dividing member.

  • Patent number: 6799643
    Abstract: The present invention relates to a percussion electrical hand-held tool having an electronic control unit (5) for controlling at least one power parameter of the electrical tool, and a substantially flat force sensor for controlling operation of the electronic control unit (5) and arranged sliding displacement-free for sensing a press-on force (F, F1) applied by a user in an operational direction of the electric tool, without being displaced, between at least two, associated with each other, press-surfaces (7a, 7b) extending at least partially transverse to a percussion axis (A) of the electrical tool.
