Definitions

  • the invention relates to a hand machine tool according to claim 1.
  • a first housing of the hand power tool has a first housing part and a second housing part.
  • the first housing part and the second housing part are to be understood here in particular as being theoretical constructions that do not exist in practice. This means that the first housing part and the second housing part are not component units that can be assembled and / or disassembled. However, it is also conceivable that the first housing part and the second housing part are designed as separate component units.
  • an electric motor drive is received by the first housing part.
  • the second housing part is designed as a handle educated.
  • the term “handle” should be understood to mean a component around which at least one hand of an operator can be placed in order to guide the hand-held power tool 10.
  • the ratio of a length of the hand power tool to a height of the first housing part should be between 1.6 and 2.8, but preferably be 2.25. This makes it particularly easy to handle.
  • the height h should be understood here to mean the geometric dimensions of the first housing part in the y direction.
  • the length I of the handheld power tool is to be understood as the dimension of the handheld power tool in the x direction.
  • the length I includes an externally visible length I 1 of the rechargeable battery that extends on an upper edge of the handheld power tool.
  • a rechargeable battery is provided as an energy source for the handheld power tool.
  • An energy source is to be understood here as a component which provides the electrical energy for the electric motor drive.

  • the first axis is advantageously coaxial with a motor axis.
  • the height h of the first housing is at least between 70 mm and 90 mm, but is preferably 80 mm.
  • the height h is defined here along the first axis.
  • At least one electronic system is provided for energizing the electromotive drive.
  • the electronics are advantageously at least partially accommodated in the second housing.
  • the rechargeable battery advantageously forms a second common axis with the second housing part, which axis penetrates the rechargeable battery.
  • the length I of the handheld power tool is between 150 mm and 200 mm, but is preferably 180 mm.
  • the length I is defined here along the second axis.
  • the length I of the handheld power tool includes a length I 1 of the rechargeable battery. Without the length I 1 of the rechargeable battery, the length I of the handheld power tool is preferably between 130 mm and 170 mm. However, the length I of the handheld power tool without the length I 1 of the rechargeable battery is particularly preferably 150 mm.
