Abstract

A cutting tool has a housing. A blade bar projects forwards from the housing along a longitudinal axis. An electric drive motor drives the blade bar. At least one battery supplies the drive motor with electrical energy. The blade bar, the drive motor and the battery are mounted on the housing. The cutting tool has a top handle arranged above a center of gravity of the hedge trimmer, and a rear handle arranged behind the hedge-trimmer center of gravity. The battery is arranged on the housing at least mainly in front of the rear handle.

First claim

What is claimed is:

1 . An outdoor power tool comprising:
a main housing having an upper side and a lower side, the upper and lower side being defined when the tool is in a horizontal orientation with a longitudinal axis of the blade bar substantially parallel to the ground; a blade bar projecting forward from the housing along the longitudinal axis; an electric drive motor for driving the blade bar arranged within the housing; at least one battery for supplying the drive motor with electrical energy arranged mainly within an outer contour of the housing; and a top handle arranged above a center of gravity of the outdoor power tool when the tool is in a horizontal orientation with the longitudinal axis of the blade bar substantially parallel to the ground, and a rear handle formed integrally with the housing and arranged behind the outdoor power tool center of gravity and the top handle when the tool is in a horizontal orientation with the longitudinal axis of the blade bar substantially parallel to the ground, the battery being arranged on the housing at least mainly in front of the rear handle, the housing having a receptacle for interchangeably accommodating the battery, wherein the receptacle has an interface for the battery that is generally accessible from the upper side of the housing, such that the battery can be inserted into an opening of the receptacle at the upper side of the housing and connected to the interface with the battery received at least partly within the receptacle, wherein, when the tool is in the horizontal orientation, the lower side of the main housing generally defines a lower plane and the blade bar projects forward from the housing entirely above the lower plane.

2 . The outdoor power tool according to claim 1 , wherein the battery is arranged on the housing in front of the drive motor as viewed in the longitudinal direction.

3 . The outdoor power tool according to claim 1 , wherein the battery is arranged on the housing in an overlapping manner with the drive motor as viewed in the height direction.

4 . The outdoor power tool according to claim 3 , wherein the battery is arranged on the housing at least partly above the drive motor.

5 . The outdoor power tool according to claim 3 , wherein the battery is arranged on the housing at least partly below the drive motor.

6 . The outdoor power tool according to claim 1 , wherein the battery is arranged on the housing at least partly in an overlapping manner with the drive motor as viewed in the lateral direction.

7 . The outdoor power tool according to claim 6 , wherein the battery is arranged on the housing laterally next to the drive motor.

8 . The outdoor power tool according to claim 1 , wherein the battery is arranged on the housing behind the drive motor as viewed in the longitudinal direction.

9 . The outdoor power tool according to claim 1 , wherein the battery has two sections which are arranged approximately symmetrically with respect to the drive motor.

10 . The outdoor power tool according to claim 1 , wherein the battery is arranged on the housing obliquely with respect to the longitudinal axis.

11 . The outdoor power tool according to claim 1 , wherein the drive motor has a motor shaft which is arranged obliquely with respect to the longitudinal axis.

12 . The outdoor power tool according to claim 11 , wherein the motor shaft is connected to the blade bar via an angular gear unit.

13 . The outdoor power tool according to claim 1 , wherein the battery is arranged on the housing on the whole in front of the rear handle as viewed in the longitudinal direction.

14 . The outdoor power tool according to claim 1 , wherein the battery has a battery center of gravity, and wherein the battery is arranged on the housing in such a way that the battery center of gravity is arranged behind the top handle as viewed in the longitudinal direction.

15 . The outdoor power tool according to claim 1 , wherein the battery is arranged on the housing on the whole behind the top handle as viewed in the longitudinal direction.

16 . The outdoor power tool according to claim 1 , wherein the interface comprises at least one of a mechanical and an electrical interface.

17 . The outdoor power tool according to claim 16 , wherein the interface on the housing is accessible from the front, in particular obliquely from the front, such that a battery is connected to the interface essentially from the front.

18 . The outdoor power tool according to claim 16 , wherein the interface on the housing is accessible obliquely from the front.

19 . The outdoor power tool according to claim 16 , wherein the interface on the housing is accessible from a side, such that a battery is connected to the interface essentially from the side.

20 . The outdoor power tool according to claim 1 , wherein the top handle is connected to the housing via at least one handle web angled relative to the top handle, the handle web engaging the housing in a region below the outdoor power tool center of gravity.

21 . The outdoor power tool according to claim 1 , wherein a handle axis of the rear handle is oriented within the range of −30° to +30° with respect to the longitudinal axis.

22 . The outdoor power tool according to claim 1 , wherein the center of gravity of the battery is arranged above the blade bar.

23 . The outdoor power tool according to claim 22 , wherein the battery is arranged completely above the blade bar.

24 . The outdoor power tool according to claim 1 , wherein the rear handle is directly coupled to the housing.

25 . The outdoor power tool according to claim 1 , wherein the rear handle is rigidly coupled to the housing.

26 . The outdoor power tool according to claim 1 , wherein the rear handle is formed by to the housing.

27 . The outdoor power tool according to claim 1 , wherein the battery is received entirely within the receptacle.

28 . An outdoor power tool comprising:
a main housing having an upper side and a lower side, the upper and lower side being defined when the tool is in a horizontal orientation with a longitudinal axis of the blade bar substantially parallel to the ground; a blade bar positionable to project forward from the housing along the longitudinal axis; an electric drive motor for driving the blade bar, arranged within the housing; at least one battery for supplying the drive motor with electrical energy, arranged mainly within an outer contour of the housing; a top handle coupled to the housing; and a rear handle formed integrally with the housing and arranged behind the top handle and an outdoor power tool center of gravity when the tool is in a horizontal orientation with the longitudinal axis of the blade bar substantially parallel to the ground, the battery being arranged on the housing in front of the rear handle, and the center of gravity of the battery being arranged generally above the longitudinal axis of the blade bar when the tool is in a horizontal orientation with the blade bar substantially parallel to the ground, and the housing having a receptacle for interchangeably accommodating the battery, wherein the receptacle has an interface for the battery that is generally accessible from the upper side of the housing, such that the battery can be inserted into an opening of the receptacle at the upper side of the housing and
