Abstract

A portable power tool, in particular a hand-held planing machine, includes at least one workpiece contact unit and at least one handle unit. The workpiece contact unit has at least one workpiece contact surface, and the handle unit has at least one main handle. The main handle has at least one maximum distance point that, in a direction extending at least substantially perpendicularly to a workpiece contact surface, has a maximum distance from the at least one workpiece contact surface. The maximum distance is less than 150 mm.

First claim

The invention claimed is:

1. A power tool system, comprising:
at least one portable power tool including:
at least one workpiece contact unit having at least one workpiece contact surface, and
at least one handle unit having a main handle, wherein at least one drive unit having at least one drive axis which interests an axis of main extent of the main handle, and
the main handle has at least one maximum distance point that, as viewed along a direction that is at least substantially perpendicular to the at least one workpiece contact surface, has a maximum distance of less than 150 mm in relation to the at least one workpiece contact surface;

at least one energy storage unit configured to be positioned in the main handle and to store power and configured such that, when positioned in the main handle as viewed along the direction that is at least substantially perpendicular to the at least one workpiece contact surface, the at least one energy storage unit is disposed at least substantially entirely above a center of gravity axis of the portable power tool; and
an operating element configured to actuate a switch, the operating element located directly above the at least one workpiece contact unit and at least in part directly beneath the at least one handle unit.

2. The power tool system as claimed in claim 1 , wherein the power tool system has a maximum total mass of less than 1.5 kg.

3. The power tool system as claimed in claim 1 , wherein the power tool system has a maximum longitudinal extent of less than 230 mm.

4. A portable power tool, further comprising:
at least one workpiece contact unit having at least one workpiece contact surface;
at least one handle unit having at least one main handle, wherein the at least one main handle has at least one maximum distance point that, as viewed along a direction that is at least substantially perpendicular to the at least one workpiece contact surface, has a maximum distance of less than 150 mm in relation to the at least one workpiece contact surface;
an operating element configured to actuate a switch, the operating element located directly above the at least one workpiece contact unit and at least in part directly beneath the at least one main handle; and
one or more of at least one open-loop and closed-loop control unit, which, as viewed along the direction that is at least substantially perpendicular to the at least the workpiece contact surface, is disposed between a center of gravity axis of the portable power tool and the workpiece contact unit.

5. The portable power tool as claimed in claim 4 , wherein the maximum distance point, as viewed along the direction that is at least substantially perpendicular to the at least one workpiece contact surface, is less than 120 mm above the at least one workpiece contact surface.

6. The portable power tool as claimed in claim 4 , including a center of gravity axis which is at least substantially parallel to the at least one workpiece contact surface and which, as viewed along the direction that is at least substantially perpendicular to the at least one workpiece contact surface, has a maximum distance of less than 90 mm in relation to the at least one workpiece contact surface.

7. The portable power tool as claimed in claim 4 , including a center of gravity axis, the portable power tool further comprising:
at least one drive unit, wherein the at least one drive unit, which, as viewed along the direction that is at least substantially perpendicular to the at least one workpiece contact surface, is disposed, at least mostly, above the center of gravity axis.

8. The portable power tool as claimed in claim 4 , further comprising at least one drive unit having at least one drive axis, which, as viewed along the direction that is at least substantially perpendicular to the at least one workpiece contact surface, has a minimum distance of greater than 45 mm in relation to the at least one workpiece contact surface.

9. The portable power tool as claimed in claim 4 , further comprising an insert tool unit and at least one drive unit configured to drive the insert tool unit, wherein the at least one drive unit, as viewed along the direction that is at least substantially perpendicular to the at least one workpiece contact surface, is disposed mostly above the insert tool unit.

10. The portable power tool as claimed in claim 4 , further comprising at least one drive unit having at least one drive axis, which intersects an axis of main extent of the at least one main handle.

11. The portable power tool as claimed in claim 10 , wherein the at least one drive axis is located forwardly of the at least one main handle and above the at least one workpiece contact surface.

12. The portable power tool as claimed in claim 11 , wherein the axis of the main extent of the at least one main handle is parallel to the at least one workpiece contact surface.

13. The portable power tool as claimed in claim 4 , further comprising:
at least one drive unit, wherein the at least one drive unit is configured as an EC motor unit.

14. The portable power tool as claimed in claim 4 , further comprising at least one insert tool unit, and at least one workpiece debris discharge unit, which, as viewed along a direction that is at least substantially parallel to the at least one workpiece contact surface, is disposed completely in front of an axis of rotation of the insert tool unit.

15. The portable power tool as claimed in claim 4 , further comprising at least one energy storage receiving unit disposed mostly in the at least one main handle.

16. The portable power tool as claimed in claim 15 , wherein the energy storage receiving unit has at least one energy storage guide element, the energy storage guide element having a main extent that is at least substantially parallel to the at least one workpiece contact surface.

17. The portable power tool as claimed in claim 4 , wherein the portable power tool is configured as a hand-held power planer.

18. A portable power tool, comprising:
at least one workpiece contact unit having at least one workpiece contact surface;
at least one handle unit having at least one main handle, wherein the at least one main handle has at least one maximum distance point that, as viewed along a direction that is at least substantially perpendicular to the at least one workpiece contact surface, has a maximum distance of less than 150 mm in relation to the at least one workpiece contact surface;
an operating element configured to actuate a switch, the operating element located directly above the at least one workpiece contact unit and at least in part directly beneath the at least one main handle; and
at least one drive unit having at least one drive axis, which intersects an axis of main extent of the at least one main handle.

19. The portable power tool as claimed in claim 18 , wherein the at least one drive axis is located forwardly of the at least one main handle and above the at least one workpiece contact surface.

20. The portable power tool as claimed in claim 19 , wherein the axis of the main extent of the at least one main handle is parallel to the at least one workpiece contact surface.
