Definitions

  • the U.S. 2014/0271013 A1 describes an angle grinder with a hood covering the grinding wheel, the grinding wheel being connected to an extension piece with an output shaft of the angle grinder.
  • the U.S. 2003/0224707 A1 describes a dust extraction hood that can be attached to an angle grinder as an additional device.
  • the hood can be made of plastic, sheet metal or cast metal and can be connected to the power tool in particular with an angular flat metal strip, so that the hood is connected to the housing of the power tool in a rotationally fixed manner.
  • the anti-rotation element formed by the metal strip can be connected on the one hand to the rear wall of the hood and on the other hand to the power tool with a screw, with which a handle is otherwise held on the housing of the power tool.
  • the anti-rotation element may have a short leg attached to the hood.
  • the hood can have a longitudinal slit, for example an arcuate slit, through which a fastening element, for example the shank of a fastening screw, protrudes.
  • a locking means can be provided with which the pivoted position of the hood relative to the base plate can be fixed.
  • the fixing means can be a metal strip with a slit, in particular an arcuate slit.
  • a clamping element can protrude into the curved slot.
  • the clamping element can be a threaded shank of a screw which is non-rotatably inserted in a hole in the rear wall.
  • a clamping nut can be screwed onto the threaded shank of the screw.
  • the clamping nut can be a wing nut.
  • the base plate can consist of two elements.
  • the base plate can have a metal body which the hood is attached. The metal body can be placed on the workpiece to be machined.
  • the invention also relates to a dust extraction device with a hood having a cavity delimited by a rear wall, a narrow wall and a work opening and a suction nozzle, wherein a circular disc-shaped processing tool can be fastened to a rotary bearing assigned to the rear wall and can be driven in rotation about an axis of rotation by an output shaft of the power tool.
  • the rear wall 3 of the housing forms an arcuate slot 28 .
  • the arcuate slot lies in relation to the axis of rotation D of the shaft extension piece 7 28 of the working opening 4 opposite.
  • a fastening screw 29 is inserted in the arcuate slot 28.
  • the fastening screw 29 has a head 29' which is followed by a square section with which the fastening screw 29 is rotationally fixed in the arcuate slot 28.
  • a dust extraction device which is characterized in that the base plate 18 forms a plastic trough 35, in which there is a sheet metal body 38, to which the means 41 forming the pivot axis S and the locking means 22 are fastened, with provision being made in particular for the locking means 22 to be a is a strip 22 cut free from the sheet metal body 38 with a slot 23 through which a clamping element 25" attached to the side wall protrudes, it being provided in particular that the edges 40 of the sheet metal body 38 are bent in a direction away from the plastic trough 35 and have snap-in hooks 37 of the plastic trough 35 are overlapped and/or that the pivot axis S is formed by screws 39 screwed into fastening eyes 41 .
