  • Patent number: 9475182
    Abstract: A hand-held power tool includes a tool housing and a handle housing. The handle housing is movable relative to the tool housing. The hand-held power tool also includes an electric motor for driving the hand-held power tool. The electric motor is switched on and off by a relative movement of the handle housing relative to the tool housing. The hand-held power tool also includes a main electrical switch configured to apply an electrical voltage supply to the electric motor. The main electrical switch is switched by an actuating mechanism. The main electrical switch is actuatable with the aid of a movable component that is movable relative to the tool housing handily via the actuating mechanism, either directly or by the actuating mechanism.

  • Patent number: 8662197
    Abstract: The disclosure relates to a method of assembling a hand machine tool having (i) an intermediate flange that includes (i) at least one base body having a slot-shaped opening extending in a bearing position and in a bearing, (ii) an intermediate shaft assembly that includes an intermediate shaft and a wobble bearing having a wobble pin, and (iii) a drive piston. The method includes sliding the drive piston onto the wobble pin, introducing the wobble pin into the slot-shaped opening such that the drive piston slides into the at least one base body, and inserting, in an assembly direction corresponding to a direction of a longitudinal axis of the base body, the intermediate shaft of the intermediate shaft assembly into a second base body of the immediate flange.

  • Publication number: 20120279741
    Abstract: An electric tool includes a vibratory means which is configured to impart a counteracting vibration which counteracts a housing vibration of the electric tool. A vibration-relevant characteristic of the vibratory means can be adapted during the operation of the electric tool in such a way that the amplitude, the phase position and/or the frequency of the counteracting vibration varies with a change in the vibration-relevant characteristic. The vibratory means of the electric tool has a natural frequency which can be varied by variation means of the electric tool. A method for compensating housing vibrations, in particular of the electric tool, includes imparting a counteracting vibration by a vibratory means which counteracts a housing vibration of the electric tool. The amplitude, the phase position and/or the frequency of the counteracting vibration is varied during the operation of the electric tool.

  • Publication number: 20120227995
    Abstract: An electric tool includes a striking mechanism assembly, which can be driven in and against a striking direction in a cyclic manner, and a counter-oscillator for compensating for vibrations of the electric tool, in particular of housing oscillations, comprising a balancing mass. The balancing mass can be driven in a movement direction by driving the striking mechanism assembly, wherein the movement direction extends at an angle to the striking direction.

  • Patent number: 8245791
    Abstract: The invention relates to a hand-held tool, in particular a rotary hammer, a percussion hammer, or a sabre saw. The hand-held tool is equipped with a drive unit and a stroke-generating element; the drive unit is embodied to move the stroke-generating element in a reciprocating fashion along a translation axis. The hand-held tool has at least one counterweight; the counterweight is operatively connected to the drive unit in such a way that it is possible to at least partially compensate for forces at least indirectly caused by the reciprocating motion. According to the invention, the counterweight in the hand-held tool is supported so that it is able to move, in particular to reciprocate, coaxial or parallel to the translation axis.
