An operation unit with an input unit and a display unit is also provided. Summary of the Invention

[0003] This invention relates to a rotating laser having a housing in which a laser unit and a leveling unit are arranged. The leveling unit includes at least one tilt sensor for determining the orientation of an axis to which the laser unit is attached relative to the housing, and at least one tilt adjustment unit for setting a preset target tilt angle of the attached axis relative to the housing. An operation unit with an input unit and a display unit is provided. The display unit is configured to visualize the preset target tilt angle of the attached axis in a first display type, specifically a first color, in a first operating mode of the rotating laser.

[0004] Therefore, the present invention can provide a rotating laser in which a simple and reliable visualization of an activated first operating mode can be achieved through a first display form.

[0005] Preferably, the display unit is configured to visualize, in a second display type, particularly a second color, the preset target tilt or current tilt of the associated axis in a second and / or third operating mode of the rotating laser.

[0006] Therefore, it is possible to safely and reliably achieve visualization of the second and third operating modes, which are different from the first operating mode.

[0007] Preferably, the first operating mode is a self-leveling mode, in which the preset target tilt corresponds to the tilt of the associated axis relative to the horizontal plane. Preferably, the second operating mode is a tilt setting mode, in which the preset target tilt corresponds to the tilt of the associated axis relative to the horizontal plane at a preset angle. Preferably, the third operating mode is a manual mode, in which the display unit displays the current tilt of the associated axis relative to the horizontal plane.

[0008] Therefore, the corresponding tilt of the associated axis relative to the horizontal plane can be assigned to each operating mode in a simple manner.

[0009] Preferably, in manual mode, the user of the rotating laser manually operates the at least one tilt adjustment unit to align the associated axis to a preset target tilt relative to the horizontal plane.

[0010] Therefore, it is easy and straightforward to align the device to a preset target angle in manual mode.

[0011] Preferably, a control and adjustment unit is provided, which operates the at least one tilt adjustment unit in at least one operating mode such that the tilt of the associated axis determined by the at least one tilt sensor is aligned to coincide with the horizontal plane or a preset target tilt of the associated axis, wherein the display unit flashes the value associated with the horizontal plane or the preset target tilt during alignment.

[0012] Therefore, the alignment process can be visualized safely and reliably.

[0013] Preferably, in at least one operating mode, when the tilt of the associated axis is adjusted to coincide with the horizontal plane and / or when the tilt coincides with a preset target tilt of the associated axis, the display unit continuously displays the value associated with the target tilt.

[0014] Therefore, visualization of the alignment of the associated axis with the horizontal plane and / or the preset target tilt angle can be achieved simply and without complexity.

[0015] The display unit is preferably configured as a segment display, wherein separate segments are provided for visualizing numerical values ​​belonging to at least one operating mode as a percentage, numerical values ​​belonging to at least one operating mode as a degree, and / or the sign of the displayed numerical values.

[0016] Therefore, it is possible to achieve specific visualizations of numerical values ​​in a simple way.

[0017] Preferably, the segment display is configured as dual-color and / or the individual segment is configured as monochrome or dual-color, or the backlight of the display unit is configured as dual-color.

[0018] Therefore, color display units can be provided easily and without complexity.

[0019] Preferably, the display unit has a first region belonging to a first tilt axis for displaying a first tilt of the associated axis along the first tilt axis, and a second region belonging to a second tilt axis for displaying a second tilt along the second tilt axis.

[0020] Therefore, a highly efficient display unit for precise and accurate display can be provided.

[0021] Furthermore, the present invention also relates to a method for displaying the tilt of the association axis of the laser unit of the rotating laser relative to the housing of the rotating laser, the rotating laser described above, the method comprising the following steps: Choose the first, second, or third operating mode. Set the target tilt angle relative to the horizontal plane, or set the current tilt angle of the associated axis relative to the horizontal plane, and In the first operating mode, the target tilt is displayed by visualization with a first display type, particularly a first color; or in the second operating mode, the target tilt is displayed with a second display type, particularly a second color; or in the third operating mode, the current tilt of the associated laser unit axis is displayed in the display unit with the second display type, particularly a second color.

[0022] Therefore, the present invention can provide a method for displaying the tilt of the associated axis of the laser unit of a rotating laser relative to a horizontal plane, wherein a simple and reliable visualization of the determined tilt can be achieved through first and second display forms.

[0023] Preferably, the value associated with the current tilt or the preset target tilt is displayed as a percentage or in degrees.

[0024] Therefore, the obtained values ​​can be displayed appropriately in a simple way.

[0025] Preferably, in the method, when the associated axis is aligned with the horizontal plane or a preset target tilt angle by the tilt adjustment unit, the target tilt angle is flashed on the display unit.

[0026] Therefore, the alignment process can be visualized safely and reliably.

[0027] In at least one operating mode, preferably, the target tilt of the associated axis or the value associated with the current tilt up to a preset value is displayed with a separator for generating decimal places, and starting from a value greater than the preset value, it is displayed with the separator disabled.

[0028] Therefore, it is possible to achieve accurate display of the determined tilt angle in a simple and uncomplicated manner. Attached Figure Description
