Abstract

A positioning aid is disclosed for a core drilling machine, having a core drill for creating a hollow-cylindrical drill hole. The positioning aid includes a light source for creating a centring pattern on a workpiece. The positioning aid is fastened in a releasable and centered manner to the core drilling machine. The positioning aid may include a laser pointer, which is releasably fastened to a centring pin.

First claim

The invention claimed is:

1. A positioning aid for a core drilling machine having a drill chuck for receiving a core drill for creating a hollow-cylindrical drill hole, comprising a light source for creating a centring pattern on a workpiece, said light source comprising a housing having a recess being configured for centred attachment to an outer surface of a centring pin being adapted for attachment within said drill chuck of said core drilling machine, and a switch for switching said light source on and off, wherein said light source is configured for generating a light field for the lighting of a working area and a centring pattern for the centring, and wherein said switch is configured for separately switching said centring pattern and said light field.

2. The positioning aid of claim 1 , wherein said light source comprises a laser pointer for creating said centring pattern.

3. The positioning aid of claim 1 , wherein said light source is permanently connected to said centring pin.

4. The positioning aid of claim 3 , wherein said recess is configured for releasably attaching onto said outer surface of said centring pin.

5. The positioning aid of claim 1 , wherein said light source is configured to be automatically switched on when mounted onto said centring pin.

6. The positioning aid of claim 1 , wherein said light source is configured for generating a light field for the lighting of a working area and a centring pattern for the centring.

7. The positioning aid of claim 6 , wherein said centring pattern comprises a first illumination, and wherein said light field comprises a second illumination, said first illumination being brighter than said second illumination.

8. The positioning aid of claim 1 , further comprising a fastening device for securing to said core drilling machine when not in use.

9. The positioning aid of claim 8 , wherein said fastening device is configured as a magnet.

10. The positioning aid of claim 1 , wherein said centring pattern comprises at least one element selected from the group consisting of a laser point, a reticle, and a circle.

11. A positioning aid for a core drilling machine with a core drill for creating a hollow-cylindrical drill hole, comprising a light source for creating a centring pattern on a workpiece, said light source being configured for releasable, centred fastening to a centring pin configured for attachment within a drill chuck of said core drilling machine, wherein said light source is configured for generating a light field for the lighting of a working area and a centring pattern for the centring, and wherein a switch is provided for separately switching said centring pattern and said light field.

12. The positioning aid of claim 11 , wherein said light source is configured for generating a light field for the lighting of a working area and a centring pattern for the centring.

13. The positioning aid of claim 12 , wherein said centring pattern comprises a first illumination, and wherein said light field comprises a second illumination, said first illumination being brighter than said second illumination.

14. A positioning aid for a core drilling machine with a core drill for creating a hollow-cylindrical drill hole, comprising:
a light source for creating a centring pattern on a workpiece, said light source comprising a housing having a recess being configured for centred attachment to an outer surface of a centring pin for said core drilling machine, and
a switch for switching said light source on and off,
wherein said light source is configured for generating a light field for the lighting of a working area and a centring pattern for the centring, and wherein said switch is configured for separately switching said centring pattern and said light field.

15. The positioning aid of claim 14 , wherein said light source comprises a laser pointer for creating said centring pattern.

16. The positioning aid of claim 14 , wherein said light source is permanently connected to said centring pin.

17. The positioning aid of claim 16 , wherein said recess is configured for releasably attaching onto said outer surface of said centring pin.

18. The positioning aid of claim 14 , wherein said light source is configured to be automatically switched on when mounted onto said centring pin.

19. The positioning aid of claim 14 , wherein said light source is configured for generating a light field for the lighting of a working area and a centring pattern for the centring.

20. The positioning aid of claim 19 , wherein said centring pattern comprises a first illumination, and wherein said light field comprises a second illumination, said first illumination being brighter than said second illumination.

21. The positioning aid of claim 14 , further comprising a fastening device for securing to said core drilling machine when not in use.

22. The positioning aid of claim 21 , wherein said fastening device is configured as a magnet.

23. The positioning aid of claim 14 , wherein said centring pattern comprises at least one element selected from the group consisting of a laser point, a reticle, and a circle.
