LASER LEVEL DEVICE WITH REFERENCE MARKING
First Claim
Patent Images
1. A laser level device, comprising:
- a housing having a first outer reference plane and a second outer reference plane;
a light exiting element exposed from the housing; and
a light emitting system within the housing;
wherein the light emitting system is configured to generate a light beam that exits the light exiting element in a direction substantially parallel to at least one of the first outer reference plane or the second outer reference plane; and
wherein the housing includes a marking element indicating a distance of the light beam to the at least one of the first outer reference plane or the second outer reference plane.

Abstract
A laser level device with a marking feature indicates a relative position of the emitting light beam/ray with respect to a geometry of the housing of the laser level device. One or more of the outer surfaces of the laser level device includes a reference plane that provides a reference to measure a distance to the laser light beam. A distance of the light beam to the reference plane may be pre-marked on another outer surface of the laser level device, which is convenient for a user to check or mark the distance in a use scenario.

18. A laser level device, comprising:
-
a housing having a first outer reference plane and a second outer reference plane; a light exiting element exposed from the housing; and a light emitting system within the housing; wherein the light emitting system is configured to generate a light beam that exits the light exiting element in a direction one of substantially level or substantially plumb; and wherein the housing includes a marking element indicating a distance of the light beam to at least one of the first outer reference plane or the second outer reference plane before or upon the light beam exiting the light exiting element. - View Dependent Claims (19)

20. A method, comprising:
-
providing a laser level device, the laser device including a housing having an outer reference plane, a light exiting element exposed from the housing, and a light emitting system within the housing that is configured to generate a light beam that exits the light exiting element in a direction one of substantially in parallel to the outer reference plane, substantially level, or substantially plumb, and the housing including a marking element indicating a marked distance of the light beam to the outer reference plane before or upon the light beam exiting the light exiting element; positioning the laser device to a first surface that is adjacent to the outer reference plane; operating the laser level device to emit the light beam; determining a measured distance between the light beam and a second surface; and determining a relative position between the first surface and the second surface by comparing the measured distance with the marked distance.
