Abstract

Laser rangefinder with a measuring unit (12), which is intended to determine a distance between a reference surface and a measurement object (14), characterized by a light source (16) which illuminates the reference surface in at least one operating state.

Description

  • State of the art
  • The invention relates to a laser rangefinder according to the preamble of claim 1.
  • A laser range finder having a measuring unit provided to determine a distance between a reference surface and a measured object has already been proposed.
  • Disclosure of the invention
  • The invention is based on a laser rangefinder with a measuring unit, which is intended to determine a distance between a reference surface and a measured object.
  • It is proposed that the laser distance measuring device has a luminous means which illuminates the reference surface in at least one operating state. A "measuring unit" is to be understood in particular as meaning a unit which is intended to determine the distance, in particular by a transit time and / or a phase position of a signal emitted by the measuring unit and reflected by the measuring object. The measuring unit preferably has a laser which emits a laser beam for determining the distance. By "provided" is intended to be understood in particular specially programmed, designed and / or equipped. In particular, a "distance" is to be understood as meaning a distance between an attachment point and the measurement object. Preferably, the attachment point is arranged in a certain position relative to the measuring unit. In particular, a "reference surface" is to be understood as meaning an area of a measurement object from which the distance is to be measured. Preferably, during the measurement process, the attachment point bears against the reference surface. A "measuring object" should be understood to mean, in particular, an object which limits the distance in at least one side during a measuring operation. Preferably, the measurement object reflects the laser beam. A "light source" is to be understood in particular as meaning a means which emits a visible light in at least one operating state. The light-emitting means has a light source which appears meaningful to the person skilled in the art, but preferably a light-emitting diode. In addition, the light source advantageously has a light guide. The inventive design of the laser rangefinder a particularly comfortable and accurate striking the reference surface is possible.
  • In a further embodiment, it is proposed that the laser range finder has a corner measuring pin, which is intended to abut against a reference surface in at least one operating state, whereby a comfortable and accurate striking on a hard to reach place of the object to be measured is possible. A "corner measuring pin" should in particular be understood to mean a means having an abutment point which is intended to rest against a location of the reference surface which is difficult to reach. The corner measuring pin preferably has a ratio between a main extension and at least one extension perpendicular to the main extension of a ratio greater than 2, preferably greater than 4, particularly preferably greater than 8. Preferably, the corner measuring pin is knife-shaped.
  • Furthermore, it is proposed that the laser rangefinder comprises a switching unit which is provided to switch on and / or off the illuminant during a stop changeover, as a result of which a particularly advantageous operation and a high-quality impression can be achieved. A "switching unit" is to be understood in particular as meaning a unit which is intended to detect a stop changeover and to provide a parameter which has at least information about the attachment point for this purpose. Preferably, a computing unit of the laser rangefinder is provided to evaluate the characteristic. In particular, a "stop changeover" is to be understood as a process in which an arrangement of the stop point is changed relative to the measuring unit.
  • drawing
  • Further advantages emerge from the following description of the drawing. In the drawing, an embodiment of the invention is shown. The drawing, the description and the claims contain numerous features in combination. The person skilled in the art will expediently also consider the features individually and combine them into meaningful further combinations.
  • It shows:
  • 1 an inventive laser rangefinder with a lighting means and a Eckenmesspin in a perspective view.
  • Description of the embodiment
  • 1 shows a laser rangefinder 10 with a measuring unit 12 , a light source 16 , a corner measuring pin 18 , a display 20 and controls 22 , The measuring unit 12 has a laser, not shown, which in a measurement a laser beam 24 sending out. A measurement object 14 reflects a part of the laser beam 24 , An unspecified sensor of the measuring unit 12 detects a part of the reflected light of the laser beam 24 , The measuring unit 12 has a computing unit, which in a measurement by means of a transit time and / or a phase position, a distance between the measuring unit 12 and the measurement object 14 certainly.
  • When measuring in a first measurement mode, the operator places the laser range finder 10 with a laser of the measuring unit 12 facing away back 26 to a reference surface, not shown here, of another measurement object or the same measurement object 14 at. The backside 26 thus has an attachment point in the first measurement mode. The arithmetic unit adds in the first measuring mode to the specific distance between the measuring unit 12 and the measurement object 14 a distance between the measuring unit 12 and the back 26 , Thus, the measuring unit 12 provided a distance between the to the back 26 adjacent reference surface and the measurement object 14 to determine. the display 20 gives the measured distance to the operator.
  • The corner measuring pin 18 is mounted on and swiveled by an operator. The measuring unit 12 has a switching unit, which is a stop switching, that is, swing in or swing out of the corner measuring pin 18 , detected. The changeover unit switches between the first measuring mode and a second measuring mode during the stop switching.
  • In a measurement operation in the second measurement mode, the operator places the laser range finder 10 with the corner measuring pin 18 to the reference surface. The arithmetic unit adds in the second measuring mode to the specific distance between the measuring unit 12 and the measurement object 14 a distance between the measuring unit 12 and an anchor point 28 of the corner measuring pin 18 , Thus, the measuring unit determines 12 in the second measuring mode, a distance between one at the anchor point 28 applying reference surface and the measurement object 14 ,
  • The light source 16 is at the back 26 of the laser rangefinder 10 arranged. In addition, the laser rangefinder could be more bulbs 16 have, for example, a circumferential light-conducting edge. Furthermore, a corner measuring pin could have a transparent and / or light-conducting material and be illuminated by a light source. The light source 16 has a light-emitting diode, not shown. The light source 16 Illuminates in the second measuring mode, the reference surface, and at a point where the corner measuring pin 18 is applied. The switching unit automatically switches on the light source in the second measuring mode. In addition, the operator can use the controls 22 the bulb 16 to switch on and off. Furthermore, the light bulb could 16 be switched together with a lighting of the display or be switched by a triggered by the operator stop switching.
