Definitions

  • the invention relates to a distance measuring device, in particular a laser distance measuring device, according to the preamble of claim 1.
  • the means for measuring the distance comprise a transmitting unit and a receiving unit, wherein a measuring signal is emitted by the transmitting unit in the direction of an object to which the distance is to be determined.
  • the measuring signal reflected on the object is received by the receiving unit, with evaluation electronics determining the distance to the object, for example by means of transit time measurement or interferometric methods. It is known to use laser light, ultrasonic waves or radar waves as the measurement signal.
  • known distance measuring devices have operating means designed as pushbuttons. Furthermore, known distance measuring devices are provided with display means designed as display in order to display the measurement result and / or inputs made via the operating means.
  • the display means and the operating means are usually located on an upper side of the distance measuring device, which is arranged substantially at right angles to an end face of the distance measuring device is, from which the measuring signal emerges and in which the measuring signal is received. Since known distance measuring devices are frequently used in heavily polluted locations, in particular on construction sites, soiling and / or damage of the display means and / or the operating means often results, which in turn leads to a shortened service life of the distance measuring device.
  • the invention is therefore based on the object to propose a distance measuring device in which the risk of damage and / or contamination is minimized.
  • the invention is based on the idea of assigning the distance measuring device a protective cover, with which the first display means and / or the first operating means, at least partially, can be covered, ie, protected.
  • the first display means and / or the first operating means by means of the at least one protective cover at least partially, preferably completely covered so that contamination of the display means and / or operating means, in particular scratching a display or a control button difficult or preferably avoided.
  • the operability in particular the handling or grip of miniaturization efforts ever smaller distance measuring devices is improved.
  • the protective cover need not exclusively have a protective function for the first display means and / or the first operating means, but the protective cover itself can, as will be explained later, as a support for operating means and / or Display means serve, in particular in distance measuring devices, in which the operating means and / or the display means would otherwise have to be made too small due to the miniaturization efforts (lack of space).
  • the invention relates to all automatic distance-measuring devices, regardless of the specific design of the means for measuring distance.
  • the means for distance measurement at least one laser transmitting unit (in particular laser diode) and a laser receiving unit (in particular photodiode), wherein the specific distance determination, for example by a transit time measurement and / or interference considerations can be done.
  • the protective cover is permanently, so captive on the distance measuring device, in particular on a housing of the distance measuring device is arranged.
  • An age Native solution provides detachably connect the protective cover with the distance measuring device, in particular with the housing of the distance measuring device to (completely) if necessary, especially if the measuring station requires this, especially for reasons of space, the protective cover.
  • the protective cover can be arranged or arranged to be pivotable relative to the first display means and / or the first operating means. This can be realized for example by an articulated connection of the protective cover to the housing of the distance measuring device.
  • an embodiment can be realized in which the protective cover is arranged displaceable relative to the first display means and / or the first operating means between an open position and a closed position, preferably parallel to a surface of the housing of the distance measuring device.
  • a roller shutter-like design of the protective cover is likewise possible, so that the protective cover, in particular in guide rails, can be guided so that the protective cover can be adjusted around an end face of the distance measuring device to a rear side of the distance measuring device.
  • first display means are arranged at least partially on the protective cover.
  • second display means eg, a second display
  • the protective cover in addition to the display means, in particular as a display. It is not absolutely necessary that the first and / or second display means (exclusively) display measurement results and / or inputs made, but that, for example, time and / or date information are displayed on the first and / or second display means.
  • the first operating means may for example consist of one or more input keys and / or scroll wheels, etc.
  • the first display means may be formed as first operating means (touchscreen).
  • further operating means for example a further group of keys and / or at least one scroll wheel
  • the operating means and / or display means are arranged on the protective cover such that they are covered by closing the protective cover.
  • the protective cover in particular on an outer side of the protective cover, at least one display means is arranged, which is visible when the protective cover is closed, for example, to display time or date functions and / or the battery level.
  • a notepad for recording is arranged on the protective cover and / or means for releasably securing a notepad are provided on the protective cover.
  • the means for releasably securing the notepad be formed for example as a retaining clip or as a latching mechanism.
  • lighting means are arranged on the protective cover with which the operating means and / or display means can be at least partially illuminated when the protective cover is open. Additionally or alternatively, the illumination means can be designed such that the distance measuring device can be used as a kind of flashlight.
