Abstract

A cut-length indicating device for a portable power tool comprises at least one indicating unit including at least one movably mounted indicating element configured to indicate at least one position of a cut edge of a machining tool in dependence on a set cut depth of the machining tool, and at least one position setting unit configured to move the indicating element into a position that is dependent on a cut-depth setting of the machining tool. The cut-length indicating device further comprises at least one adjusting unit configured to adapt at least one maximum setting movement distance of the indicating element to at least one machining-tool parameter of the machining tool.

First claim

What is claimed is:

1. A cut-length indicating device for a portable power tool, a cut-length defined between opposite cut edges of a machining tool when the machining tool is at a set cut depth within a workpiece, comprising:
at least one indicating unit including at least one movably mounted indicating element configured to indicate at least one position of a cut edge of the machining tool in dependence on the set cut depth of the machining tool;
at least one position setting unit configured to move the indicating element into a position that is dependent on a cut-depth setting of the machining tool; and
at least one adjusting unit configured to adapt at least one maximum setting movement distance of the indicating element to at least one machining-tool parameter of the machining tool, wherein the adjusting unit, for the purpose of adapting the at least one maximum setting movement distance of the indicating element, is configured to set at least one maximum distance between two connection regions of at least one guide element of the position setting unit on which the indicating element is movably mounted.

2. The cut-length indicating device according to claim 1 , wherein the adjusting unit is further configured to adapt the at least one maximum setting movement distance of the indicating element to at least one machining-tool diameter of the machining tool.

3. The cut-length indicating device according to claim 1 , wherein:
the at least one maximum setting movement distance has an initial adjustment state; and
the adjusting unit includes at least one resetting element configured to enable at least partial automatic resetting of the at least one maximum setting movement distance of the indicating element to return to said initial adjustment state.

4. The cut-length indicating device according to claim 1 , wherein the adjusting unit includes at least one operating element configured to adapt the at least one maximum setting movement distance of the indicating element to at least one machining-tool parameter of the machining tool.

5. The cut-length indicating device according to claim 1 , wherein:
the adjusting unit includes at least one adjusting-tool receiving interface configured to adapt the at least one maximum setting movement distance of the indicating element to the at least one machining-tool parameter of the machining tool, and
the adjusting-tool receiving interface is configured for detachable engagement to an adjusting tool.

6. The cut-length indicating device according to claim 1 , further comprising:
at least one output unit configured to output at least one adjustment parameter of the adjusting unit.

7. A cut-length indicating device for a portable power tool, a cut-length defined between opposite cut edges of a machining tool when the machining tool is at a set cut depth within a workpiece, comprising:
at least one indicating unit including at least one movably mounted indicating element configured to indicate at least one position of a cut edge of the machining tool in dependence on the set cut depth of the machining tool;
at least one position setting unit configured to move the indicating element into a position that is dependent on a cut-depth setting of the machining tool; and
at least one adjusting unit configured to adapt at least one maximum setting movement distance of the indicating element to at least one machining-tool parameter of the machining tool, wherein the adjusting unit includes at least one self-inhibiting unit configured to prevent an inadvertent adjustment of the at least one maximum setting movement distance of the indicating element.

8. The cut-length indicating device according to claim 7 , wherein the adjusting unit is further configured to adapt the at least one maximum setting movement distance of the indicating element to at least one machining-tool diameter of the machining tool.

9. The cut-length indicating device according to claim 7 , wherein the adjusting unit, for the purpose of adapting the at least one maximum setting movement distance of the indicating element, is configured to set at least one maximum distance between two connection regions of at least one guide element of the position setting unit on which the indicating element is movably mounted.

10. The cut-length indicating device according to claim 7 , wherein:
the at least one maximum setting movement distance has an initial adjustment state; and
the adjusting unit includes at least one resetting element configured to enable at least partial automatic resetting of the at least one maximum setting movement distance of the indicating element to return to said initial adjustment state.

11. The cut-length indicating device according to claim 7 , wherein the adjusting unit includes at least one operating element configured to adapt the at least one maximum setting movement distance of the indicating element to at least one machining-tool parameter of the machining tool.

12. The cut-length indicating device according to claim 7 , wherein:
the adjusting unit includes at least one adjusting-tool receiving interface configured to adapt the at least one maximum setting movement distance of the indicating element to the at least one machining-tool parameter of the machining tool, and
the adjusting-tool receiving interface is configured for detachable engagement to an adjusting tool.

13. The cut-length indicating device according to claim 7 , further comprising:
at least one output unit configured to output at least one adjustment parameter of the adjusting unit.

14. A portable power tool, comprising:
at least one cut-depth setting unit configured to set a maximum cut depth of a machining tool, wherein when the machining tool is at the maximum cut depth within a workpiece the machining tool defines opposite cut edges corresponding to the cut length in the workpiece; and
at least one cut-length indicating device including (i) at least one indicating unit including at least one movably mounted indicating element configured to indicate at least one position of a cut edge of the machining tool in dependence on the set cut depth of the machining tool, (ii) at least one position setting unit configured to move the indicating element into a position that is dependent on the cut-depth setting of the machining tool, and (iii) at least one adjusting unit configured to adapt at least one maximum setting movement distance of the indicating element to at least one machining-tool parameter of the machining tool,
wherein the adjusting unit, for the purpose of adapting the at least one maximum setting movement distance of the indicating element, is configured to set at least one maximum distance between two connection regions of at least one guide element of the position setting unit on which the indicating element is movably mounted.

15. The portable power tool according to claim 14 , further comprising:
at least one housing unit on which the at least one adjusting unit of the cut-length indicating device is disposed such that the at least one adjusting unit can be operated from outside the at least one housing unit.
