Definitions

  • the present invention relates to a device for holding a hand-held power tool.
  • the device can serve as an interface between the hand-held power tool and a support or carrying structure and comprises a first and a second fastening means and a counter structure.
  • the interface can be adapted to different hand-held power tools or types of hand-held power tools by means of an adjustable distance between the first fastening means and the counter structure or an adjustable diameter of the counter structure.
  • the invention relates to a use of the proposed interface for fastening a hand-held power tool to a support structure, as well as a corresponding method.
  • Heavy power tools such as drilling, chiseling or combination hammers, as well as core drilling machines, are often used in serial or long-term applications.
  • the user In order to compensate for the forces that occur, especially weight forces, the user is exposed to high physical strain, which can cause rapid fatigue or even physical damage. Therefore, many users strive to use support structures in which the handheld power tools can be hung or latched in order to reduce the physical strain.
  • These body-worn and/or external support structures can at least partially absorb the forces that occur and thus enable the user to work with the handheld power tool for longer. Possible designs of known support structures are described in Fig.1 shown.
  • a mounting bracket for a working device such as a brush cutter
  • the mounting bracket is designed to be flexible and transverse to a slot, so that the slot can be widened.
  • the elastic properties of a clamp are used to connect the clamp to a working tool.
  • an arrangement for a machine tool comprising an eyelet device so that the machine tool can be attached to a safety belt by means of the eyelet device and a tensioning belt.
  • the US 2017 0042 314 A1 discloses a machine tool that can be carried with a sling around the shoulder of a user.
  • a disadvantage of the suspension solutions for hand-held power tools known from the prior art is that the elastic properties of materials, ropes or mounting clamps are often used to create a connection between a hand-held power tool and a support structure.
  • Such connections based on the elasticity of a material are hardly suitable for use in connection with hammering and/or rotating hand-held power tools, as they absorb the vibrations that can occur when working with the hand-held power tools and can, for example, resonate.
  • the absorption of the vibrations can also lead to a weakening of the connection between the hand-held power tool and the support structure, which in the worst case can lead to the connection breaking down.
  • a fastening solution for a hand-held power tool to a support structure would be desirable that is user-friendly and less susceptible to the vibrations that occur when working with the hand-held power tools.
  • the technical solution to be provided should ensure optimal balancing of the hand-held power tool in relation to the Support structure to make working with the handheld power tool even easier.
  • the technical solution to be provided could be used as universally as possible for a large number of different handheld power tools or types of handheld power tools.
  • the object of the present invention is to provide solutions for the technical needs described above and to provide a fastening solution for connecting a hand-held power tool to a support structure which overcomes the deficiencies and disadvantages of the prior art.
