Definitions

  • the present invention relates to a device for receiving a handheld power tool.
  • the device can serve as an interface between the handheld 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 handheld power tools or types of handheld power tools by 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 handheld power tool to a support structure, as well as a corresponding method.
  • Heavy power tools such as drill, chisel or combination hammers, as well as core drilling devices, are often used in serial or long-term applications.
  • the user In order to compensate for the forces that occur, in particular weight forces, the user is exposed to high physical stress, which can cause rapid fatigue or even physical damage. Therefore, many users endeavor to reduce the physical stress to use support structures in which the hand-held power tools can be suspended or latched.
  • These body-borne and / or external support structures can at least partially absorb the forces that occur and thus enable the user to work longer with the hand-held power tool. Possible configurations of known support structures are shown in Fig. 1 shown.
  • the DE 10 2016 013 145 A discloses a mounting bracket for a work implement, such as a brushcutter.
  • the receiving clip is designed to be flexible and to run transversely to a slot, so that the slot can be widened.
  • elastic properties of a receiving clip are thus used to connect the clip to an implement.
  • a disadvantage of the suspension solutions for handheld power tools known from the prior art is that the elastic properties of materials, ropes or mounting clips are often used to establish a connection between a handheld 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 handheld power tools, since they absorb the vibrations that can occur when working with the handheld power tools and, for example, can come into resonance. The absorption of the vibrations can also lead to a weakening of the connection between the handheld power tool and the support structure, which in the worst case can lead to the connection being broken.

  • the provision of two contact areas (18, 19) enables the hand-held power tool (2) to be suspended in the device (1) with little vibration.
  • the retaining ring of the basic structure (11) advantageously surrounds the neck of the handheld power tool (2), so that a particularly stable connection between the handheld power tool (2) and the device (1) can be achieved in this way.
  • Fig. 8 shows a side view of the second preferred embodiment of the interface (1).
  • the first fastening means (7) and the basic structure (11) can be clearly seen in the front area (16) of the interface (1), the first fastening means (7), which is preferably designed as a hook, having a first contact area (18) between the handheld power tool (2) and the device (1) forms, while the base structure (11), which is preferably designed as a retaining ring, forms a second contact area (19) between the handheld power tool (2) and the device (1).
