Definitions
- the invention relates to a distance measuring device according to the preamble of claim 1 and a use according to claim 11.
- Distance measuring devices which determine the distance to this object on the basis of the evaluation of a measuring signal which is reflected on an object. It is known to use laser light, ultrasound or radar as the measurement signal. The actual distance measurement is based, for example, on a transit time measurement of the measurement signal or on interferometric measurement methods. The determined measurement result is then displayed on a display as display content.
- measurement applications often occur in which the distance measuring device has to be held in such a way that the display content can no longer be read by the user from the front, ie in the horizontal direction.
- Examples of such measuring applications are measuring on a wall or measuring a window width.
- the fact that the display content can not be optimally read in these frequently occurring measurement applications is perceived as uncomfortable by users of such distance measuring devices.
- To read the display contents these must cover the entire distance measuring device. turn it around so that the contents of the display are readable from the front.
- the invention is therefore based on the object to propose a distance measuring device which can be comfortably operated even in measuring applications in which the distance measuring device has to be turned relative to the user.
- the invention is based on the idea to provide a distance measuring device with means for rotating the entire display content and / or a subsection of the display content, wherein the means are designed such that the display content or the at least a subsection of the display content by at least one predetermined or individually predefinable rotation angle in the display, ie relative to the display, is rotatable.
- the core idea of the invention is a Distance measuring device, which is equipped with means for distance measurement and a display for displaying a display content, equipped with a so-called pivot function, as it is known for example from modern computer monitors.
- the twisting function can be realized by software and / or hardware.
- the display content or a subsection of the display content can be rotated relative to the distance measuring device or relative to the display by at least one predefined or predefinable angle of rotation, it is possible for the user to optimally read the display content from various relative positions to the display, especially in the case that the distance measuring device is rotated relative to the user for special measuring tasks.
- at least one measurement result, at least one input made using input means and / or date and / or time functions, etc. can be displayed as the display content or as a subsection of the display content.
- the angle through which the display content is rotated by the means for rotating the display content at least approximately corresponds to the angle at which the distance measuring device is rotated relative to the user.
- the display content or the at least one subsection of the display content is rotatable relative to the distance measuring device in at least one, preferably in several 90 ° rotation steps.
- the realization of the rotatability of the display content or of the subsection of the display content by 90 °, preferably in several 90 ° increments, enables the user to be able to read the display contents well in almost all imaginable rotational positions of the distance measuring device.
- the display is designed as a TFT display (liquid crystal display).
- the means for rotating the display content is assigned at least one input unit, wherein as a result of the actuation of the input unit by the user of the display content or the subsection of the display content is rotated.
- the input unit can be specified in which rotational position of the display content or the subsection of the display content is to be rotated relative to the distance measuring device.
- the input means preferably four input options, for example in the form of a cross-shaped input key with four input contacts, with the respective desired rotational position can be selected.
- the input unit by means of the input unit to be rotated portion of the display content can be selected.
- the input unit is designed such that it can be used to select whether the entire display content or only a subsection of the display content should preferably be rotated by a predefinable angle of rotation.
- the display content or the subset of the display content section of the display content is automatically rotated.
- the means for rotating the display content or the subsection of the display content associated with at least one position sensor, by means of which the orientation or the position of the distance measuring device and / or the display can be determined, wherein the means for rotating the display content or the subsection of the Display contents the display content or the subsection are formed in rotation depending on the position sensor information.
- the position sensor is designed to determine the orientation of the distance measuring device and / or of the display relative to a predetermined or individually predeterminable reference plane. It is particularly advantageous if this reference plane is a horizontal plane and / or a vertical plane, with the position sensor so the rotational position of the distance measuring device or the display relative to the vertical and / or horizontal can be determined.
- this reference plane is a horizontal plane and / or a vertical plane, with the position sensor so the rotational position of the distance measuring device or the display relative to the vertical and / or horizontal can be determined.
- the display or the display content and / or the subsection of the display content can be displayed in a simple manner in the event that the display content or the subsection of the display content is rotatable through 90 ° or in several 90 ° increments, it can be represented in a simple manner It is advantageous if the display or the display content and / or the subsection of the display content is contoured in a square or the display content and / or the subsection of the Displayin- haltes has the same number of pixels in the high and in the transverse direction.
- an embodiment can be realized in which the display and / or the subsection of the display content have / have a different number of pixels in two directions extending at right angles to one another.
- the means for rotating the display content or the subsection of the display content are designed such that they take into account the different extension in two mutually perpendicular directions of the display or a subsection of the display content.
- the means can display content depending on the rotational position, for example, identical, or stretch the display content depending on the rotational position in at least one display direction and / or compress.
- the distance measuring device is designed as a laser distance measuring device
- the measuring signal by means of which a distance to an object is measured, that is designed as a laser beam.
- the means for distance measurement comprise at least one laser beam source and a receiving unit, with which a laser beam reflected at the object can be received.
- the means comprise an evaluation unit, which determines the distance to the object, for example, by measuring the travel time of the laser beam and / or by interferometric methods.
- the distance measuring device in which it is designed as a hand-held device, which is selected by the user, preferably with the aid of Only one hand, relative to the user is rotatable.
- the rotation function ie the means for rotating the display content and / or at least a portion of the display content, manually activated and / or manually deactivated is formed.
- This embodiment is advantageous, in particular in combination with automatically operating means for rotating the display content or the subsection of the display content.
- the invention also leads to the use of means known per se for rotating a display content and / or at least a subsection of the display content as a means for rotating the display content or the subsection of the display content in a display of a distance measuring device.
