Abstract

A device for setting the miter angle of a machine tool is disclosed. The device includes a clamping block having at least one slot, and a pivot lever on which the machine tool can be mounted and which is pivotable about a pivot point relative to the clamping block between a minimum and a maximum miter angle. The slot includes at least two stop elements offset relative to one another. A setting mechanism includes a lever element for the selection of a maximum miter angle, where the lever element includes a mating stop element is alignable in such a way corresponding to the rotational alignment of the lever element that the mating stop element is able to strike the respective stop element in accordance with the selected maximum miter angle and by which the pivoting movement of the pivot lever relative to the clamping block can be limited.

First claim

The invention claimed is:

1. A device for setting a miter angle of a machine tool, comprising:
a clamping block with a slot, wherein the slot includes at least two stop elements that are positioned offset relative to one another at a first end of the slot;
a pivot lever, wherein the machine tool is mountable on the pivot lever and wherein the pivot lever is pivotable around a pivot point relative to the clamping block between a minimum miter angle and a maximum miter angle; and
a setting mechanism that includes a lever element for selection of the maximum miter angle, wherein the lever element includes a mating stop element that strikes a respective one of the at least two stop elements based on a selected maximum miter angle;
wherein the at least two stop elements include a first stop element, a second stop element, and a third stop element and wherein the mating stop element respectively strikes each of the first stop element, the second stop element, and the third stop element to set a respective corresponding first miter angle, a second miter angle, and a third miter angle;
wherein the setting mechanism further includes an indicator and limiting element, wherein the indicator and limiting element includes an indicator scale and an elongated recess, wherein the indicator scale indicates a selectable maximum miter angle, and wherein the elongated recess guides and limits a rotational motion of the mating stop element.

2. The device according to claim 1 , wherein the machine tool is a circular saw.

3. The device according to claim 1 , wherein the mating stop element is a protrusion.

4. The device according to claim 1 , wherein the lever element includes the mating stop element on a first side of the lever element and wherein the lever element includes a first protrusion and a second protrusion on a second side of the lever element.

5. The device according to claim 4 , wherein the first protrusion is tapered.

6. The device according to claim 4 , wherein the second side defines a cavity and wherein a first elastic protrusion and a second elastic protrusion are disposed in the cavity.
