Abstract

A hand-held power tool includes a machine housing, in which an electric drive motor is arranged that is paired with an output shaft for rotatably driving an insert tool, at least one battery pack, and a support device for guiding the machine housing on a workpiece. The support device has a support section, which has a foot plate for contacting the workpiece that includes a passage for the insert tool. The battery pack is arranged in a first machine section, the electric drive motor is arranged in a second machine section, and a handle for a user is arranged in a third machine section, at least in some sections. The three machine sections are arranged next to one another along a transverse axis, which is aligned at an angle to the output shaft of the drive motor.

First claim

1 . A hand-held power tool, comprising:
a machine housing; an electric drive motor arranged in the machine housing, the electric drive motor having an output shaft configured to rotatably drive an insert tool; at least one battery pack configured to provide energy to the electric drive motor; and a support device configured to guide the machine housing on a workpiece, the support device having a support section for the machine housing and a foot plate configured to contact the workpiece, the foot plate defining a passage for the insert tool, wherein the at least one battery pack is arranged in a first machine section, the electric drive motor is arranged in a second machine section, and a handle for a user is arranged at least partially in a third machine section, and wherein the first, second, and third machine sections are arranged next to one another along a transverse axis, which is aligned at an angle to the output shaft of the drive motor.

2 . The hand-held power tool according to claim 1 , wherein the at least one battery pack is arranged at a connection interface aligned substantially parallel to the output shaft of the drive motor on the machine housing and is replaceable.

3 . The hand-held power tool according to claim 1 , wherein the foot plate continues into a lateral widening section.

4 . The hand-held power tool according to claim 3 , wherein the lateral widening section is supported against the support section by at least one support structure.

5 . The hand-held power tool according to claim 3 , wherein the at least one battery pack is at a vertical distance from the lateral widening section of the foot plate.

6 . The hand-held power tool according to claim 2 , wherein the connection interface is arranged at a battery-side end region of the machine housing, and an electronic control device is integrated into the battery-side end region.

7 . The hand-held power tool according to claim 5 , wherein the drive motor is arranged, at least partially, in an insert tool-side end region of the machine housing, which is received and fixed at least in sections in the support section of the support device.

8 . The hand-held power tool according to claim 1 , wherein the handle in the third machine section surrounds the machine housing coaxially at least in regions.

9 . The hand-held power tool according to claim 1 , wherein:
a machine center of gravity is defined at a predetermined distance relative to a workpiece-facing side of the foot plate that is less than an overall length of the machine housing, and the machine center of gravity is arranged at least approximately between the first and second machine sections.

10 . The hand-held power tool according to claim 1 , wherein the handle is designed for one-handed operation of the hand-held power tool.

11 . The hand-held power tool according to claim 1 , wherein the hand-held power tool is at least one of a router and a trimmer.

12 . The hand-held power tool according to claim 1 , wherein the transverse axis is aligned at least approximately perpendicularly to the output shaft of the drive motor.
