- the necessary contact pressure must be applied to the surface of the working tool 11 in a substantially vertical direction.
- the device 10 must be moved in alternating grinding direction, z. B. in the direction indicated in Fig. 2 Gepatiuselibilsauscardi 21 and transversely thereto.
- Grip surface 20 makes it possible to run the device 10 with one hand and with the second hand for processing, for. B. for grinding, necessary contact force directly above the surface of the working tool 11, in particular of the grinding tool 12, apply. Furthermore, a one-hand operation on each of the two handles 19 and 20 is possible.
- the additional Grip surface or the additional handle 20 have shown in FIG. 1 a nose-like to the left projecting contour with projection 22. This allows the handling of the device 10 can be improved.
- devices 10 with battery power supply 17 compared to power supplies usually a lower weight and lower power. Because of the lower weight, a larger proportion of the contact pressure must be applied by the user when processing by means of a device 10. This is facilitated by the additional handle 19 and the additional grip surface or the additional handle 20, wherein the handle 19 not only allows the most accurate guidance of the device 10 but also additionally for transmitting the contact pressure on the surface of the
- Working tool 11 can contribute.
- the handle 19 is at a distance above the working surface of the working tool 11 and thereby laterally next to this.
- the handle 19 is thus completely or at least largely outside the installation space of the device 10, which is limited by the vertical projection of the working surface of the working tool 11.
- the additional grip surface 20 or the additional handle lies in the vertical direction over the working surface of the
- the handle 19 has a significantly elongated shape, although in another embodiment, not shown, for. B. also a spherical shape can be used.
- the handle 19 is formed by the elongated shape and the cross-sectional configuration as a hand-encompassing encompassing handle. It has cross-sectional areas which are preferably round, oval and / or angular. Also, cross-sectional areas of the handle 19 of the aforementioned
- the length of the handle 19 may be approximately between 7 cm and 10 cm, but even longer sizes are conceivable.
- z. B. be a length of at least 9.5 cm.
- the handle 19 may be fixedly and permanently connected to the housing 13. It can be attached to the housing 13 or placed on it. Instead, the handle 19 with the housing 13 may also be integral. In other configurations, the handle 19 z. B. releasably connected to the housing 13 while z. B. with respect to the housing 13 adjustable and fixable in the respective adjusted position.
- the elongated handle 19 may be positioned obliquely with its longitudinal central axis 23 at an angle with respect to the plane of the working tool 11 upwards and / or to the side and / or be adjustable to such positions. In the second embodiment shown in Fig. 4, the handle 19 with his
- Adjustments could be particularly advantageous in which the handle 19 is pivoted about a vertical axis and locked in the desired position. Instead, or in addition to a pivoting adjustment with subsequent locking about such a transverse axis is possible, as the longitudinal central axis 23 in Fig. 4 horizontally and transversely to
- Housing longitudinal alignment 21 runs.
