Definitions

  • the invention is based on a hand tool according to the type of the main claim.
  • Different versions of dust extraction devices e.g. for orbital sanders - deal with the absorption and transfer of the grinding dust (see e.g. DE-PS 34 13 028), but only provide an unchangeable position of the dust container if the dust container is placed directly on the tool (see e.g. EP-PS 01 68 531 or DE-GM 70 40 819). It is disadvantageous in these known designs that the dust collection container hinders the grinding process or the view from the workpiece when machining hard-to-reach places.
  • Dust collection containers that are separate from the working device and are connected to the sleeper by a flexible hose, at least in the first place, restrict the degree of freedom of the worker, which is why attempts have been made to minimize this hindrance by combining the dust extraction and supply lines (see, for example, DE- OS 25 12 435).
  • a relatively thick feed or discharge in turn reduces the maneuverability of the machine.
  • the arrangement according to the invention with the characterizing features of the main claim has the advantages of better maneuverability in poorly accessible places and a better view of the workpiece compared to versions with a fixed position of the dust collection container.
  • the greater manageability is advantageous, since only a thin, preferably electrical feed line emanates from the device, which hinders handling much less than a suction line.
  • FIG. 1 shows a top view of the conventional arrangement of the dust collection container on an orbital sander in an unchangeable position
  • FIG. 2 shows the same hand power tool to which the dust collection container according to an embodiment of the invention is shown 3 and 4, the hand-held power tool according to FIG. 2 is shown in a top view and a side view, the dust collection container being connected to the machine in a changed position.
  • the orbital sander 1 shown in Figure 1 has a connecting piece 2, to which a dust collector 5 is connected in a known manner. The latter can only be connected to the machine in this one predetermined position.
  • the dust collecting container 5 is connected to the connecting piece 2 via two pipe bends 3 and 4.
  • the pipe bends 3 and 4 form, each individually, a right angle and can be rotated at their junctions with the connecting piece 2 and the dust collector 5, as well as with each other, so that the position of the dust collector 5 to the machine 1 adapted to the respective conditions is selected can be.
  • the fit of the plug-in connection of the pipe bends with a circular cross-section is dimensioned such that the frictional torque present at the connection points forming the joints is greater in every position than the moment caused by the weight of the filled dust-collecting container 5.
  • the pipe bends 3 and 4 have a polygonal cross section. Here changes in the position of the dust collecting container 5 can be achieved by repositioning the pipe bends 3 and 4.
