Abstract

Claims (39)

1 . A saw blade guiding device for a saw, comprising:

at least one guide unit configured to guide a saw blade of the saw in a sawing operation, the at least one guide unit comprising two guide elements, which together form a guide holder for the saw blade, the guide holder having a width that is adjustable by the two guide elements,

wherein at least one guide element of the two guide elements has, on a side facing the other guide element of the two guide elements, at least two guide faces, each of which is configured to, depending on a guiding position of the guide element, form a side face of the guide holder, and

wherein the at least two guide faces of the guide element are arranged offset with respect to one another at least substantially parallel to an extent of the width of the guide holder.

2 . The saw blade guiding device according to claim 1 , wherein:

the at least one guide element is movably mounted such that movement of the at least one guide elements adjusts the width of the guide holder and

the at least one guide element has at least two guiding positions and, in a first guiding position of the at least two guiding positions, a first guide face of the at least two guide faces forms the side face of the guide holder and, in a second guiding position of the at least two guiding positions, a second guide face of the at least two guide faces forms the side face of the guide holder.

3 . The saw blade guiding device according to claim 2 , wherein:

in order to adjust the width of the guide holder, the guide element is rotatable about an axis of rotation of the guide element, and

the at least two guide faces of the guide element are arranged offset in a circumferential direction with respect to one another about the axis of rotation.

4 . The saw blade guiding device according to claim 2 , further comprising:

at least one holding unit, which is at least substantially fixed to a housing in order to retain the at least one guide unit,

wherein the at least one guide unit comprises at least one fixing structure,

wherein the at least one guide element is movably mounted relative to the at least one holding unit in order to adjust the width of the guide holder, and

wherein the at least one fixing structure is configured to fix the at least one guide element in at least one of the at least two guiding positions relative to the holding unit.

5 . The saw blade guiding device according to claim 4 , wherein:

the at least one fixing structure includes a plurality of fixing structures arranged on the at least one guide element, and

individual fixing structures of the plurality of fixing structures are configured to fix the guide element to the at least one holding unit in one of the at least two guiding positions in a frictional and/or interlocking manner.

6 . The saw blade guiding device according to claim 2 , wherein the at least one guide unit comprises at least one reset element configured to counteract movement of the at least one guide element from one of the at least two guiding positions.

7 . The saw blade guiding device according to claim 2 , wherein

the other guide element comprises at least two further guide faces on a side facing the at least one guide element, each of the two further guide faces forming another side face of the guide holder, and

the at least two further guide faces of the other guide element are arranged offset with respect to one another at least substantially parallel to the extent of the width of the guide holder.

8 . The saw blade guiding device according to claim 7 , wherein:

the other guide element is designed configured to be movably coupled to the at least one guide element to adjust the width of the guide holder, and

in the at least two guiding positions of the guide element and the other guide element, other respective guide faces of the guide element and the other guide element form the guide holder.

9 . The saw blade guiding device according to claim 3 , wherein:

the at least two guide faces comprises three guide faces, each of which is configured to form the side face of the guide holder,

the three guide faces are arranged offset with respect to one another at least substantially parallel to the extent of the width of the guide holder,

the three guide faces are arranged at a regular distance distributed about the axis of rotation, and

the three guide faces each extend over an angular range of at least 90° about the axis of rotation.

10 . A jig saw, comprising:

at least one saw blade guiding device comprising:

at least one guide unit configured to guide a saw blade of the saw in a sawing operation, the at least one guide unit comprising two guide elements, which together form a guide holder for the saw blade, the guide holder having a width that is adjustable by the two guide elements,

wherein at least one guide element of the two guide elements has, on a side facing the other guide element of the two guide elements, at least two guide faces, each of which is configured to, depending on a guiding position of the guide element, form a side face of the guide holder, and

wherein the at least two guide faces of the guide element are arranged offset with respect to one another at least substantially parallel to an extent of the width of the guide holder.

11 . The saw blade guiding device according to claim 1 , wherein the saw blade guiding device is configured for a jigsaw.

12 . The saw blade guiding device according to claim 1 , wherein the guide holder is configured to guide an untoothed saw blade back.

13 . The saw blade guiding device according to claim 1 , wherein the guide holder is configured to guide an untoothed saw blade back.

14 . The saw blade guiding device according to claim 8 , wherein the other guide element is movably coupled to the at least one guide element in a rotatable manner about an axis of rotation.
