Abstract

A laser level system including a laser level, the laser level projecting at least one laser line. The system also includes a bracket on which the laser level is mounted and a battery pack. The bracket includes a battery pack receptacle into which the battery pack is removably coupled. The battery pack powers the laser level. The battery pack has a maximum initial battery pack voltage (measured without a workload) of at least 18 volts. The system also includes at least one electrical conductor which delivers power from the battery pack in the battery pack receptacle to the laser level.

Claims (43)

1. A laser level assembly, comprising:

a laser level; and

a bracket;

wherein the bracket includes a base portion, a battery pack receptacle portion and a mounting portion;

wherein the laser level is mounted on the base portion;

wherein the mounting portion is perpendicular to the base portion and includes at least one magnet for mounting the bracket to a structure;

wherein the battery pack receptacle portion is configured to receive a battery pack;

wherein the laser level is configured to project at least two laser lines.

2. The laser level assembly of claim 1 , wherein the laser level is rotatably mounted to the base portion.

3. The laser level assembly of claim 2 , wherein the laser level is rotatable about a vertical axis.

4. The laser level assembly of claim 2 , wherein the laser level is rotatable about an axis that is generally parallel to a surface of the structure to which the mounting portion is mounted.

5. The laser level assembly of claim 2 , further comprising an electrical connection from the battery pack mounting portion through the base portion to the laser level.

6. The laser level assembly of claim 2 , wherein the battery pack has a maximum initial battery pack voltage, measured without a workload, of at least 18 volts.

7. The laser level assembly of claim 2 , wherein rotation of the laser level is limited.

8. The laser level assembly of claim 2 , wherein rotation of the laser level is limited to 355 degrees or less.

9. The laser level assembly of claim 1 , wherein the battery pack receptacle portion includes a pair of rails and an electrical connector configured to engage the battery pack.

10. The laser level assembly of claim 9 , wherein the electrical connector is disposed between the pair or rails.

11. The laser level assembly of claim 1 , wherein the two laser lines comprise a vertical laser line and a horizontal laser line.

12. The laser level assembly of claim 1 , wherein the mounting portion includes at least six magnets.

13. The laser level assembly of claim 1 , wherein the mounting portion includes at least eight magnets.

14. A laser level assembly, comprising:

a laser level; and

a bracket;

wherein the bracket includes a base portion, a battery pack receptacle portion and a mounting portion;

wherein the laser level is mounted on the base portion;

wherein the mounting portion is perpendicular to the base portion;

wherein the battery pack receptacle portion is configured to receive a removable battery pack;

wherein the laser level is configured to project a vertical laser line and a horizontal laser line; and

wherein the laser level is rotatably mounted to the base portion.

15. The laser level assembly of claim 14 , wherein the laser level is rotatable about a vertical axis.

16. The laser level assembly of claim 15 , further comprising an electrical connection from the battery pack mounting portion through the base portion to the line laser level.

17. The laser level assembly of claim 16 , wherein the mounting portion includes at least six magnets.

18. The laser level assembly of claim 17 , wherein rotation of the laser level is limited to 355 degrees or less.

19. A laser level assembly, comprising:

a laser level; a

a bracket including a base portion, a battery pack receptacle portion and a mounting portion;

a removable battery pack engaged with the bracket at the battery pack receptacle portion;

wherein the laser level is mounted on the base portion;

wherein the mounting portion is transverse to the base portion and includes at least one magnet;

wherein the removable battery pack has a maximum initial battery pack voltage, measured without a workload, of at least 18 volts;

further comprising an electrical connection from the battery pack mounting portion through the base portion to the laser level; and

wherein the laser level is configured to project a vertical laser line and a horizontal laser line.

20. The laser level assembly of claim 19 , wherein the battery pack receptacle portion includes a pair of rails and an electrical connector configured to engage the battery pack.
