Definitions

  • the invention relates to a motor-driven hand tool for grinding, with an elongated housing in which on the one hand a motor drive connected thereto, rotatably mounted drive shaft is provided, wherein the housing serves as a handle at one end and at the other end a particular triangular grinding tool , which is displaceable by the drive shaft in motion, is provided outside the housing.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a motor-driven hand tool for grinding, with which also in the other applications described above, a good and ergonomic operation is possible.
  • a motor-driven hand tool for grinding with an elongate housing, in which on the one hand a motor drive connected thereto, rotatably mounted drive shaft is provided, wherein the housing serves as a handle at one end and a particular at the other end triangular grinding tool, which is displaceable by the drive shaft in motion, is provided outside of the housing, wherein the end is formed with the grinding tool as between a aligned with the rest of the housing housing alignment and a pivotable about the rest of the housing in approximately rectangular pivot head and; wherein the drive shaft is connected via at least one intermediate element with a first coupling part in the swivel head and the grinding tool is associated with a second coupling part, which is in engagement with the first coupling part.
  • the orientation of the grinding tool can be changed to the handle and adapted to the specific needs.
  • the pivot axis of the pivoting head may be formed concentrically with the axis of rotation of the intermediate element, so that by a coaxial design of the bearing and power transmission as small as possible Passage is given and thus the weakening of the housing and the space requirement are kept low.
  • the pivot axis of the swivel head can be aligned approximately at a 45 ° angle to the longitudinal extent of the elongate housing, so that with a technically simple design by a simple pivoting 180 °, the desired change in alignment by 90 ° can be achieved.
  • the second coupling part is designed as a bevel gear.
  • FIGS. 1 and 2 show a motor-driven hand tool 1 for grinding.
  • the hand tool 1 comprises an elongated housing 2, in which a motor drive 3 is provided with a rotatably mounted drive shaft 4 connected thereto.
  • the one end of the housing 2 serves as a handle 5, and at the other end an approximately triangular grinding tool 6 is provided outside of the housing 2.
  • the end of the housing 2 with the grinding tool 6 is formed as a pivoting head 7, which is arranged by means of a pivot bearing 7 pivotally mounted on the housing 2.
  • the swivel head 7 is located between an aligned with the rest of the housing 2 alignment (see. Fig. 2 ) and to the rest of the housing 2 in approximately rectangular orientation (see. Fig. 1 ) pivotable.
  • the drive shaft 4 is provided with a gear 9 which is in engagement with a provided on the located in the housing 2 end of the intermediate drive shaft 11 inner bevel gear 10.
  • the intermediate drive shaft 11 is in the region of the rotary bearing 8 of the pivoting head 7 in the pivoting head 7 in and is formed coaxially with the pivot bearing 8.
  • the grinding tool 6 is assigned a bevel gear 12 formed as a second coupling part, which is in engagement with a provided at the located in the swivel head 7 end of the intermediate drive shaft 11 and formed as a gear 13 second coupling part.
  • the pivot axis of the swivel head 7 is aligned at an angle of approximately 45 ° to the longitudinal extension of the elongated housing 2.
