Abstract

A hand-held power tool, in particular an angle grinder, includes a drive unit, a machine housing, and a user interface unit. The machine housing surrounds the drive unit. The drive unit is configured to transmit a motion to an output unit. The user interface unit is configured to operate the hand-held power tool, and is either (i) positioned on an inner element of the hand-held power tool, in particular a flat outer surface of the inner element, or (ii) connected to the inner element, in particular the flat outer surface of the inner element.

First claim

What is claimed is:

1. A hand-held power tool, comprising:
a drive unit configured to transmit a motion to an output unit;
a machine housing that surrounds the drive unit in a first plane;
an inner element completely surrounded by the machine housing in a second plane; and
a user interface unit configured to operate the hand-held power tool, and at least one of (i) positioned on the inner element, and (ii) connected to the inner element.

2. The hand-held power tool of claim 1 , wherein:
the user interface unit is positioned on or connected to a flat outer surface of the inner element; and
an inner surface of the inner element faces toward a cavity in which the drive unit is located.

3. The hand-held power tool of claim 1 , wherein the inner element is one of (i) a motor housing of the drive unit, and (ii) an air guide element.

4. The hand-held power tool of claim 1 , wherein the machine housing completely surrounds the user interface unit in at least one of the first plane and the second plane.

5. The hand-held power tool of claim 1 , wherein:
an inner surface of the user interface unit faces toward a cavity in which the drive unit is located; and
the machine housing overlaps the user interface unit such that portion of the machine housing is located directly outwardly of an outer surface of the user interface unit in a plane parallel to the second plane.

6. The hand-held power tool of claim 5 , wherein the machine housing overlap is on a side facing away from the inner element.

7. The hand-held power tool of claim 1 , wherein the user interface unit is materially bonded to the inner element.

8. The hand-held power tool of claim 7 , wherein the user interface unit is materially bonded to the inner element via at least one of adhesive bonding, positive engagement, clamping, non-positive engagement, and tensioning.

9. The hand-held power tool of claim 1 , wherein the user interface unit includes:
a first user interface element that includes a human-machine interface configured to actuate or indicate a function of the hand-held power tool; and
a second user interface element that includes an actuating element configured to actuate the drive unit.

10. The hand-held power tool of claim 1 , wherein the machine housing is formed from a shell construction, and includes a machine-housing shell.

11. The hand-held power tool of claim 1 , wherein the machine housing is formed from a barrel construction, and includes a machine-housing barrel.

12. The hand-held power tool of claim 1 , wherein the machine housing includes a delimitation recess configured to receive the user interface unit such that the user interface unit is viewable by a user through the delimitation recess.

13. The hand-held power tool of claim 12 , wherein:
an outer surface of the inner element delimits the delimitation recess; and
the user interface unit is positioned on the outer surface.

14. The hand-held power tool of claim 12 , wherein:
an inner surface of the inner element faces toward a cavity in which the drive unit is located; and
an outer surface of the inner element delimits the delimitation recess.

15. The hand-held power tool of claim 1 , further comprising:
a sealing element positioned in a gap between the user interface unit and the machine housing and sealing the gap between the user interface unit and the machine housing.

16. The hand-held power tool of claim 1 , wherein the first plane is orthogonal to the second plane.
