Abstract

A handheld power tool includes at least one housing unit, at least one tool receptacle, at least one operating unit that has at least one operating element, and at least one electrical and/or electronic indication unit. The indication unit has at least one at least partially circumferentially arranged indication element that is configured to indicate at least one handheld power tool characteristic variable. The indication element in one embodiment is arranged on the housing unit in a region between the operating element the tool receptacle The indication element in another embodiment is arranged at least substantially adjacent to the operating element.

First claim

What is claimed is:

1. A handheld power tool, comprising:
at least one housing unit including at least one curved surface, the at least one housing unit defining a main direction of extent of the handheld power tool;
at least one tool receptacle;
at least one operating unit having at least one operating element; and
at least one electrical and/or electronic indication unit having at least one at least partially circumferentially arranged indication element arranged on the at least one curved surface and configured to indicate at least one handheld power tool characteristic variable,
wherein the indication element is arranged on the housing unit in a region between the operating element and the tool receptacle along the main direction of extent,
wherein the indication element extends around an entire maximum overall circumferential extent of the housing unit, and
wherein the indication unit further comprises at least one projection unit that is configured to project at least one handheld power tool characteristic variable onto a machining tool arranged on the tool receptacle.

2. The handheld power tool according to claim 1 , wherein the indication element is arranged on the housing unit close to an output movement axis of the at least one tool receptacle.

3. The handheld power tool according to claim 1 , wherein the indication element terminates at least substantially flush with an outer surface of the housing unit.

4. The handheld power tool according to claim 1 , wherein the indication unit has at least one further indication element that has a main extent running at least substantially perpendicular to a main extent of the indication element.

5. The handheld power tool according to claim 1 , wherein the indication unit has at least one electrical and/or electronic graphic indication element that is at least partially circumferentially arranged on the housing unit.

6. The handheld power tool according to claim 5 , wherein the indication element at least partially forms the graphic indication element.

7. The handheld power tool according to claim 1 , wherein the indication unit has at least one electrical and/or electronic graphic indication element that is arranged at least substantially adjacent to the indication element.

8. The handheld power tool according to claim 5 , wherein the graphic indication element is of touch-sensitive design.

9. The handheld power tool according to claim 7 , wherein the graphic indication element is of touch-sensitive design.

10. The handheld power tool according to claim 1 , wherein a minimum spacing between the indication element and the operating element is less than 20 mm.

11. The handheld power tool according to claim 1 , wherein the indication element is configured to electrically and/or electronically indicate the at least one handheld power tool characteristic variable.

12. The handheld power tool according to claim 1 , wherein the indication element includes at least one of a luminous element cover, a light conductor, a reflector, a luminous element, an individual LED, a printed circuit board with multiple LEDs, a backlit indication unit, a matrix indication unit, an LCD display, an OLED display, and electronic paper.

13. The handheld power tool according to claim 5 , wherein the graphic indication element is configured to visually depict at least one of alphabetic characters, diagrams, symbols, pictograms, images, and films via at least one of a line display, an LCD, an AMOLED, an LED display, a multi-line display, and at least five interconnected LED-type luminous strips.

14. The handheld power tool according to claim 7 , wherein the graphic indication element is configured to visually depict at least one of alphabetic characters, diagrams, symbols, pictograms, images, and films via at least one of a line display, an LCD, an AMOLED, an LED display, a multi-line display, and at least five interconnected LED-type luminous strips.

15. The handheld power tool according to claim 1 , wherein the at least one housing unit houses a drive unit having an axis of rotation, and the main direction of extent of handheld power tool is at least substantially parallel to the axis of rotation.

16. The handheld power tool according to claim 8 , wherein the graphic indication element is a touch-sensitive display.

17. The handheld power tool according to claim 1 , wherein the at least one projection unit is oriented so as to emit a projection corresponding to the at least one handheld power tool characteristic variable onto the machining tool.

18. The handheld power tool according to claim 1 , wherein the at least one handheld power tool characteristic variable projected onto the machining tool by the projection unit is a colored marking corresponding to a machining tool wear.
