Definitions

  • the invention is based on a hand tool according to the preamble of claim 1.
  • US 3 160 995 discloses a hand tool for grinding surfaces close to the edge, in particular in corners or along fillets.
  • the hand tool has a sanding plate with a triangular base. Its working movement swings back and forth about a fixed axis that is normal to the base. The axis penetrates the grinding disc geometrically near a forward-facing corner.
  • the angle of the corner in the front area of the sanding plate is less than 90 °, so that the sanding plate can be used for sanding in the outermost, near-edge areas of corners or fillets.
  • the edges of the grinding tool are curved, as is also known in the case of irons, for grinding flush at hard-to-reach places. bulges, as is also known with irons, for flush grinding in hard-to-reach places.
  • the layout of the sanding plate designed as an equilateral triangle with curved side edges, has, like all such triangles, three corner angles, each less than 90 °.
  • hand-held machine tools with a rectangular grinding plate which, by means of an eccentric drive, perform a tied, circular movement.
  • These hand-held machine tools are referred to as orbital sanders, although their tool does not actually perform any oscillating movement.
  • a grinding machine is known with a rotating grinding plate driven via a flexible shaft, which is overlapped by a shell-like, fixed protective hood, which is supported with its shell-like edge on a workpiece to be machined and which has a pipe socket and one Hose is connected to a vacuum cleaner, which can suck up grinding dust to the outside .
  • the hand tool according to the invention with the characterizing features of claim 1 has the advantage of simple design, convenient quick change of the tool, especially the sanding sheet together with the sanding plate, without auxiliary tools, or the simple fastening and unlocking, for example, for turning and cleaning the sanding plate.
  • the tool holder does not necessarily have to be designed like a shell.
  • the grinding plate is held securely in the area of the bolt in that the bolt engages under a locking hook on the grinding plate on its side facing the tool holder .
  • the grinding plate is held particularly securely under pretension on the tool holder by, in addition to at least one latching hook, one-piece support means, in particular support claws, carries, which are supported on the tool holder and by the tool holder, in particular on the side facing the grinding plate, preferably near an engagement opening for the support claws of the grinding plate, in particular cams and support bevels, which are braced against the grinding plate, in particular against its supporting claws .
  • the pre-tensioned mounting position of the grinding plate on the tool holder which can be rotated by 120 ° in each case, is ensured by the fact that one locking hook and two supporting claws are arranged on each of the grinding plate corners.
  • the integrated design of the tool holder together with the oscillating elements such that the tool holder on the side facing away from the sanding plate carries, in particular in one piece, elastic oscillating elements which hold the tool holder securely on the machine housing against rotational entrainment and against loss, enables particularly economical production of the tool holder together with the Vibrating elements.
  • the passage of dust between the sanding plate and the tool holder is ensured in every mounting position of the sanding plate in the same quality by forming an intermediate space between the sanding plate and the tool holder which, apart from the dust extraction openings and a mouth of a dust removal channel, is essentially sealed to the outside and serves for the passage of the extracted dust.
  • the dust extraction leaves the view of the workpiece undisturbed by arranging a, in particular rectangular, mouth of a dust removal channel centrally on an outside of the tool holder.
  • the path for the dust extraction from the workpiece to the channel outlet is short and streamlined in that the mouth is connected to the machine housing via a, in particular rectangular, bellows.
  • the bellows is arranged so that it can be easily plugged in between the tool holder and the machine housing and also serves as a further vibration-damping element for the tool holder or for the grinding plate.
  • the sanding plate on the tool holder can be replaced quickly and easily with other tools with the same clip-on fastening structure, such as scraper, saw blade, separating plate or the like, without auxiliary tools.
  • the grinding plate with the mounted tool holder rise above the base like a truncated pyramid. Vibrations of the hand tool during grinding are effectively reduced with little effort, in that the eccentric pin carries a leveling compound between the lower roller bearing and the tool holder.
  • the tool holder is designed with a triangular base or contour that substantially matches the base of the grinding plate and is supported with its outer edge on the grinding plate, a particularly light, material-saving design of the tool holder is possible, with a hollow shape due to the shell shape Space is created opposite the sanding plate, which is particularly easy to pass for the extracted grinding dust and which can accommodate the components of the control button and holding means of the sanding plate.
  • the sanding plate and the tool holder are constructed symmetrically and the corners of the sanding plate can be locked and / or latched to the corners of the tool holder, it is possible to quickly and precisely twist the sanding plate by 120 ° relative to its original position position so that when the grinding effect of the first corner area of the sanding plate and the sanding sheet, e.g. in the event of wear or soiling, the second and third corner areas can be used instead of the first or second for further corner grinding, the corner always being directed exactly to the front. Since the sanding plate is a wearing part, the quick repositioning of the corner areas in relation to the tool holder or the easy interchangeability of the sanding plate is of considerable advantage.
  • Both the tool holder and the grinding plate thus have features of the invention, the tool holder also being an important component or spare part on which differently equipped grinding plates or other tools can be exchanged or releasably or locked without an auxiliary tool.
