Abstract

A bearing device of a portable power tool, in particular a router, has at least one main body unit. The main body unit is formed as a corner guiding unit and has a bearing surface and a lead-through opening. The bearing surface is configured to bear on a workpiece. The lead-through opening is configured to receive an insert tool configured to perform work on a workpiece.

Claims

1. A bearing device of a portable power tool comprising:

at least one main body unit configured as a corner guiding unit having;

at least one bearing surface configured to bear on a workpiece; and

at least one lead-through opening through which an insert tool configured to perform work on a workpiece is led.

2. The bearing device of claim 1, wherein the at least one main body unit has at least two guiding edges which run substantially perpendicularly to each other when considered in a plane which runs substantially parallel to the at least one bearing surface.

3. The bearing device of claim 2, wherein the at least one main body unit further comprises:

a further guiding edge configured as an arc of a circle, the at least two guiding edges connected to each other via the further guiding edge.

4. The bearing device of claim 1, further comprising:

at least one guiding-device receiving unit configured to fix a guiding device positively and/or non-positively on the main body unit, the at least one guiding-device receiving unit having at least one guiding-device receiving element having a longitudinal extent that extends substantially parallel to one of the at least two guiding edges.

5. A portable power tool with a bearing device comprising:

at least one main body unit configured as a corner guiding unit having;

at least one bearing surface configured to bear on a workpiece; and

at least one lead-through opening through which an insert tool configured to perform work on a workpiece is led.

6. The portable power tool of claim 5, further comprising:

at least one housing unit having a transverse direction of extent, the at least one housing unit, when mounted on the at least one main body unit, encloses an angle of less than 60°

with one of at least two guiding edges of the main body unit.

7. The portable power tool of claim 6, wherein the transverse direction of extent is an angle bisector with respect to an angle enclosed by the at least two guiding edges.
