Abstract

The present disclosure relates to a battery powered tool (1) extending in a longitudinal direction (Z), comprising a tool body (10) and a battery pack (20), which battery pack is arranged on the tool body and adapted to power the tool. The tool body is provided with a through aperture adapted to receive the battery pack, such that the tool body at least partly surrounds the battery pack.

Claims

1. A battery powered tool extending in a longitudinal direction, comprising:

a tool body;

a battery pack, wherein the battery pack is configured to be installed into the tool body to power the battery powered tool;

an electric motor configured to be powered by the battery pack and drive an operating part of the battery powered tool during operation; and

wherein the tool body is provided with a through aperture defined by a continuous enclosure extending through the tool body in an elongation direction perpendicular to the longitudinal direction of extension of the battery powered tool, wherein the longitudinal direction of extension of the battery powered tool is defined by the operating part, and wherein the tool body is configured to receive the battery pack into the through aperture by insertion of the battery pack in the elongation direction of the through aperture such that the tool body surrounds a perimeter of the battery pack when the battery pack is received in the through aperture, wherein the battery pack comprises sidewalls extending in the elongation direction between opposing ends of the battery pack, wherein the perimeter is defined around the sidewalls between the opposing ends, and wherein the opposing ends of the battery pack are visible when the battery pack is received in the through aperture of the tool body;

wherein the battery powered tool further comprises;

a first handle affixed to the tool body at a rear of the tool body opposite the operating part and along the longitudinal direction, and

a second handle affixed to the tool body, the second handle being positioned forward of the through aperture and rearward of the operating part along the longitudinal direction.

2. The battery powered tool according to claim 1, wherein a length of the battery pack is substantially the same as a length of the through aperture.

3. The battery powered tool according to claim 1, wherein at least one end of the battery pack protrudes outside the tool body when mounted in the through aperture.

4. The battery powered tool according to claim 1, wherein each of the opposing ends of the battery pack protrude outside the tool body in two directions along the elongation direction of the through aperture when the battery pack is mounted in the through aperture.

5. The battery powered tool according to claim 4, wherein the each of the opposing ends of the battery pack are adapted to protrude in substantially equal amounts in the two directions.

6. The battery powered tool according to claim 1, wherein the tool body is provided with a connector within the through aperture, which connector is adapted to integrate with a corresponding connector on the battery pack when the battery pack is mounted in the through aperture.

7. The battery powered tool according to claim 1, wherein the battery pack is visible from the outside when mounted in the through aperture.

8. The battery powered tool according to claim 1, wherein the battery powered tool is provided with an indicator adapted to indicate whether or not the battery pack is correctly fitted in the through aperture.

9. The battery powered tool according to claim 1, wherein the battery pack comprises a locking device adapted to lock the battery pack to the tool body.

10. The battery powered tool according to claim 1, wherein the tool is a handheld garden tool.

11. The battery powered tool according to claim 1, wherein the tool is a handheld forestry tool.

12. The battery powered tool according to claim 1, wherein the portion of the battery pack surrounded by the tool body is not visible.

13. The battery powered tool according to claim 12, wherein no part of the battery pack extends outside of the tool body.

14. The battery powered tool according to claim 12, wherein at least one of the opposing ends extends outside of the tool body.

15. The battery powered tool according to claim 12, wherein the opposing ends extend outside the tool body by an equal distance.

16. The battery powered tool according to claim 1, wherein the operating part comprises a vegetation trimmer or a chain saw.

17. The battery powered tool according to claim 1, wherein the second handle is oriented parallel to the elongation direction.

18. A battery powered tool comprising:

a tool body;

an operating part affixed to and extending from the tool body in a longitudinal direction;

a first handle affixed to the tool body at a rear of the tool body opposite the operating part;

a through aperture passing through the tool body and externally open and visible at ends of the through aperture, the through aperture being positioned forward of the first handle along the longitudinal direction, the through aperture extending through the tool body in an elongation direction that is directed through the externally open visible ends of the through aperture;

a second handle affixed to the tool body, the second handle being positioned forward of the through aperture and rearward of the operating part along the longitudinal direction; and

a battery pack configured to be received in the through aperture such that opposing ends of the battery pack are externally visible through the ends of the through aperture; and

an electric motor configured to be powered by the battery pack and drive the operating part during operation of the battery powered tool;

wherein the through aperture is configured to receive the battery pack into the through aperture by insertion of the battery pack in the elongation direction of the through aperture.

19. The battery powered tool of claim 18, wherein the operating part comprises a vegetation trimmer or a chain saw.

20. The battery powered tool of claim 18, wherein a weight of the battery pack is balanced with respect to the longitudinal direction.
