Abstract

The present disclosure relates to a laser level system. The laser level system includes a laser level, a quick connect tool mounting bracket, and/or other components. The laser level may be mounted to the quick connect tool mounting bracket in one or more different orientations via a quick connect adapter. The quick connect adapter may be removably coupled with the bracket and/or one or more quick connect mounts supported by one or more external surfaces a housing of the laser level. One or more laser beams generated by the laser level may be controlled via a controller to visually indicate whether the laser level is in a “manual” mode, whether the laser level is in a “self-leveling” mode, and/or whether the laser level is “out of level” while in the “self-leveling” mode. In some embodiments, the laser level system includes a self-leveling mechanism lock.

First claim

What is claimed is:

1. A laser level system, the laser level system comprising a laser level, the laser level comprising:
a housing including a plurality of external surfaces;
a first quick connect mount supported by the housing and disposed in a first orientation, the first quick connect mount being configured to removably engage a quick connect tool mounting bracket in the first orientation;
a second quick connect mount supported by the housing and disposed in a second orientation that differs from the first orientation, the second quick connect mount being configured to removably engage the quick connect tool mounting bracket in the second orientation;
at least one laser generator disposed in the housing and configured to emit at least one laser beam;
a self-leveling mechanism disposed in the housing and configured to orient the at least one laser beam in a predetermined direction relative to gravity; and
further comprising one or more optical components disposed in the housing and configured to convert the at least one laser beam into a horizontal fan beam and a vertical fan beam that intersects the horizontal fan beam.

2. The system of claim 1 , wherein the first quick connect mount comprises a first slot in the housing, and wherein the second quick connect mount comprises a second slot in the housing.

3. The system of claim 1 , wherein the first quick connect mount is disposed on an opposite side of the housing from the second quick connect mount.

4. The system of claim 1 , further comprising a third quick connect mount supported by the housing and disposed in a third orientation that differs from the first and second orientations, the third quick connect mount being configured to removably engage the quick connect tool mounting bracket in the third orientation.

5. The system of claim 4 , wherein the first, second, and third orientations are generally orthogonal to each other.

6. A laser level system, the laser level system comprising a laser level, the laser level comprising:
a housing including a plurality of external surfaces;
a first quick connect mount supported by the housing and disposed in a first orientation, the first quick connect mount being configured to removably engage a quick connect tool mounting bracket in the first orientation;
a second quick connect mount supported by the housing and disposed in a second orientation that differs from the first orientation, the second quick connect mount being configured to removably engage the quick connect tool mounting bracket in the second orientation;
at least one laser generator supported by the housing and configured to emit at least one laser beam; and
a self-leveling mechanism supported by the housing and configured to orient the at least one laser beam in a predetermined direction relative to gravity; and
further comprising a quick connect tool mounting bracket comprising:
a clamp configured to removably clamp to an external base support; and
a quick connect portion connected to the clamp, the quick connect portion being configured to alternatively and removably engage either of the first and second quick connect mounts so as to connect the housing to the quick connect tool mounting bracket in either the first or second orientation.

7. The system of claim 6 , wherein the clamp is connected to the quick connect portion via first and second serial ball-and-socket mechanisms, the balls of the first and second ball-and-socket mechanisms being spaced from each other.

8. The system of claim 6 , wherein:
the quick connect portion comprises one of a slot and a protrusion with an enlarged head;
the first and second quick connect mounts each comprise the other of the slot and the protrusion with the enlarged head; and
the slot and enlarged head are configured to releasably engage each other so as to provide a quick connect connection between the laser level and the quick connect tool mounting bracket.

9. The system of claim 6 , wherein the first quick connect mount is disposed on an opposite side of the housing from the second quick connect mount.

10. The system of claim 6 , further comprising a third quick connect mount supported by the housing and disposed in a third orientation that differs from the first and second orientations, the third quick connect mount being configured to removably engage the quick connect tool mounting bracket in the third orientation.

11. The system of claim 10 , wherein the first, second, and third orientations are generally orthogonal to each other.

12. The system of claim 6 , further comprising one or more optical components configured to convert the at least one laser beam into a horizontal fan beam and a vertical fan beam that intersects the horizontal fan beam.

13. A laser level system, the laser level system comprising:
a housing including a plurality of external surfaces;
at least one laser generator supported by the housing and configured to emit at least one laser beam;
a self-leveling mechanism supported by the housing and configured to orient the at least one laser beam in a predetermined direction relative to gravity; and
a controller configured to control the at least one laser generator, the controller having at least the following user-selectable modes:
an off mode wherein the at least one laser generator is off;
a self-leveling mode wherein,

responsive to the housing being tilted to less than or equal to a tilt angle threshold level, the at least one laser generator is on and the self-leveling mechanism orients the at least one laser beam in the predetermined direction relative to gravity,
responsive to the housing being tilted past the tilt angle threshold level, the controller is configured to provide a visually perceptible out-of-level indication; and
a manual mode wherein the controller is configured to sequentially turn the at least one laser generator on and off repetitively to provide a visually perceptible manual mode indication,
wherein the out-of-level indication is different than the visually perceptible manual mode indication.

14. The laser level system of claim 13 , further comprising a self-leveling mechanism lock having an ON state that deactivates the self-leveling mechanism and locks an orientation of the at least one laser beam into a locked position relative to the housing, regardless of the orientation of the housing relative to gravity,
wherein the controller is configured to place the self-leveling mechanism lock in its ON state when in the manual mode.

15. The laser level system of claim 14 , wherein the self-leveling mechanism comprises a pendulum pendulously supported by the housing, and wherein the self-leveling mechanism lock prevents pendulous movement of the pendulum relative to the housing when the self-leveling mechanism lock is in its ON state.

16. The system of claim 15 wherein the first quick connect mount comprises a first slot in the housing, and wherein the second quick connect mount comprises a second slot in the housing.

17. The laser level system of claim 14 , wherein the controller is configured to place the self-leveling mechanism lock in its ON state when in the off mode.

18. The laser level system of claim 14 , wherein, when the controller is in the manual mode such that the self-leveling mechanism lock is in its ON state, at least one of the at least one laser beams is projected from the housing in a direction that is parallel to a reference surface defined by the housing regardless of the orientation of the housing relative to gravity.
