Definitions

  • the spring element can also be referred to as an elastomer spring element, elastomer spring or elastomer element.
  • the spring element can be made from any other elastic deformable material.
  • the spring element can be made from a foamed material. This means that the spring element can have pores.
  • the material can be open-pore or closed-pore.
  • the material can be a foam.
  • the spring element can also be solid.
  • the spring element can also comprise a metallic material.
  • the spring element can be a wire mesh, an adjustable leaf spring or the like.
  • the spring element is tubular.
  • the spring element is linearly displaceable along a longitudinal direction of the spring element to adjust the spring stiffness of the spring element.
  • the longitudinal direction can coincide with an axis of symmetry of the handle section or can be oriented parallel to this.
  • the handheld power tool can be, for example, a hammer drill, a chisel hammer, a core drill, a saw, a grinder, a screwdriver, a bolt feed tool or the like.
  • the handheld power tool preferably has a housing with a main handle and the previously explained handle.
  • the handle is preferably laterally connected to the housing.
  • the handle can therefore also be called a side handle.
  • the handle is detachably connected to a cylindrical fastening section of the housing.
  • the handle can be pushed onto the fastening section of the housing and then fixed to the fastening section by twisting the grip section. Conversely, the handle can also be released from the hand-held power tool by relaxing the fastening section.
  • a handle 5 is detachably fastened to the fastening section 4.
  • “Detachable” here means that the handle 5 can be separated from the fastening section 4 and connected to it again.
  • the handle 5 can also be rotatably attached to the fastening section 4.
  • the handle 5 in the Orientation of the Fig. 1 pushed from the left to the right onto the fastening section 4 and pulled from the fastening section 4 from the right to the left.
  • the handle 5 is in particular a so-called side handle or can be referred to as a side handle.
  • the handle 5 comprises a handle section 6, which can be gripped by a user to operate the handheld power tool 1, and a preferably annular fastening section 7, which can be detachably connected to the fastening section 4 of the housing 2.
  • the spring element 19 is an elastomer spring element or can be referred to as such.
  • the spring element 19 has a hollow cylindrical geometry with an annular base.
  • the geometry of the spring element 19 extends along the axis of symmetry M6 in the longitudinal direction L19.
  • the spring element 19 is there rotationally symmetrical to the axis of symmetry M6.
  • the spring element 19 can, for example, be glued to the spring element holder 18 or vulcanized to it. That is, the spring element 19 can be integrally connected to the spring element holder 18. In the case of integral connections, the connection partners are held together by atomic or molecular forces. Integral connections are non-detachable connections that can only be separated by destroying the connecting means.
