Definitions

  • the present invention relates to a hand tool for drilling, chiselling or combined drilling chiseling tools.
  • the hand tool includes a percussion, before the return of which the user is protected by vibration-damping decoupling between the percussion and a handle.
  • the hand tool of the invention has a tool holder for receiving a chiselling, drilling or drilling chiseling tool and a striking mechanism.
  • the percussion mechanism is arranged in a machine housing.
  • a handle is oriented along a tilted to the working axis, inclined by at least 70 degrees or perpendicular handle axis and applied with three suspensions on the machine housing.
  • the first suspension is located closer to the working axis than the second suspension.
  • the third suspension is offset from the first suspension and the second suspension along the working axis, for example offset in the direction of impact.
  • the second suspension has a lever arm extending along the handle axis.
  • the first end of the lever arm is attached to one of the machine housing and handle.
  • a guide is attached to the other of the machine housing and handle.
  • the second end of the lever arm is forced in the guide on a tilted or perpendicular to the working axis path against a spring device deflected.
  • the arrangement of the three suspensions is particularly suitable for a hand tool, the focus is outside the working axis.
  • the first suspension may be located closer to the working axis than the second suspension.
  • the second suspension isolates by means of the guide the vibration damping along the handle axis of a required connection along the working axis.
  • the spring device and the lever arm can be designed independently of each other in order to optimize the vibration damping in the individual directions.
  • One embodiment provides to provide the second end of the lever arm for further decoupling with a pivot bearing.
  • the lever arm may be formed as a leaf spring, which geometrically has a high rigidity along the handle axis and a low rigidity along the working axis.
  • the third suspension has a in a linear guide parallel to the working axis sliding pivot bearing whose axis of rotation is perpendicular to a plane spanned by the working axis and the handle axis.
  • the third suspension allows the handle to move freely for damping the recoil along the working axis.
  • the pivot bearing reduces the transmission of the torque of the power tool around its center of gravity.
  • the guide allows only parallel to the working axis displacement of the machine housing relative to the handle.
  • the rotary bearing complements the translatory degree of freedom of the guide by a rotational degree of freedom, the axis of rotation of the pivot bearing, however, remains within the leadership. Other translational or rotational movements are inhibited by the third suspension.
  • the third suspension can be advantageously arranged at the height of the intermediate racket.
  • the percussion has successively arranged on the working axis in the direction of impact a racket and an intermediate racket.
  • the intermediate bat lies between the bat and the tool.

  • the exciter 12 is coupled via an eccentric 15 or a wobble finger to the motor 5 and forced to a periodic, linear movement.
  • An air spring formed by a pneumatic chamber 16 between exciter 12 and racket 13 couples a movement of the racket 13 to the movement of the exciter 12 at.
  • the racket 13 transmits part of its impulse to the drill bit 4 indirectly via an intermediate racket 17 substantially resting during operation .
  • the motor 5, the percussion 6 and other drive components of the chisel hammer 1 are arranged in a continuous, one-piece or multi-part machine housing 18 .

  • the linear guide 35 may be formed, for example, by an elongated groove extending parallel to the working axis 11 in the machine housing 18 .
  • the groove has for example a length of 1 cm to 2 cm, which corresponds approximately to the lifting height 29 of the first suspension 24 .
  • the handle 7 has, for example, a cylindrical pin which engages in the groove. The pin can rotate in the groove about its axis forming the axis of rotation 44 . Similarly, the pin may be provided on the machine housing 18 and the groove in the handle 7 .
