Abstract

A method for applying a position marking for a working position to a substrate, for example a wall, a ceiling, a floor or the like, at a marking position assigned to it, comprising: a. unsystematically or systematically moving a portable marking system over a marking area of the substrate; b. determining at least one position of the marking system; c. marking at the determined position of the marking system, provided that the determined position coincides with the marking position or at least coincides with the marking position to a predefined or predefinable degree of accuracy. The invention also relates to a marking system.

First claim

1 . A method for applying a position marking for a working position to a substrate, at a marking position assigned to the substrate, comprising:
a. unsystematically or systematically moving a portable marking system over a marking area of the substrate; b. determining, at least one position of the portable marking system; c. marking at the at least one determined position of the marking system provided that the at least one determined position coincides with the marking position or at least coincides with the marking position to a predefined or predefinable degree of accuracy.

2 . The method as claimed in claim 1 , including establishing a stationary coordinate system in relation to the substrate.

3 . The method as claimed in claim 1 , including determining at least one position of the portable marking system.

4 . The method as claimed in claim 1 , including determining at least two positions and/or a position range of the marking system in parallel.

5 . The method as claimed in claim 1 , including using a marking unit with at least two markers for marking at the at least one determined position.

6 . The method as claimed in claim 1 , wherein a user moves the portable marking system manually over the marking area according to b.

7 . The method as claimed in claim 1 , including marking the position marking on and/or in a building or a building element.

8 . The method as claimed in claim 1 , including marking several position markings within the marking area.

9 . The method as claimed in claim 1 , including first moving the portable marking system to a starting point within the marking area as part of an initial positioning.

10 . A portable marking system for marking a position marking on a substrate at a marking position assigned to the position marking, comprising
a marking unit with at least one marker; a position determining system for detecting a position of the marking system and a control unit which is set up to mark a position marking or at least part of the position marking on the substrate at least once by the marking unit if the marking system is at the marking position or is in a measuring range corresponding to a predefined or predefinable degree of accuracy around the marking position, and not to mark a marking if the marking system is outside the measuring range.

11 . The marking system as claimed in claim 10 , wherein the marking system has a handle.

12 . The marking system as claimed in claim 10 , wherein the marking system has a guide rod and/or a receptacle for a guide rod.

13 . The marking system as claimed in claim 10 , wherein the marking system has at least one distance sensor, a structured light source in connection with a structured-light-receiving and evaluation unit, a transit time sensor and/or an acceleration sensor.

14 . The marking system as claimed in claim 10 , wherein the marking system has a tachymeter and/or is set up for communication with a tachymeter.

15 . The marking system as claimed in claim 10 , wherein the marking system comprises a motorized means of transport or in that the marking system can be arranged on the motorized means of transport.

16 . The marking system as claimed in claim 10 , wherein the marking system is set up to apply to the surrounding area a light geometry projected onto the surrounding area.

17 . The method of claim 1 , wherein the substrate is a wall, a ceiling, or a floor.

18 . The method of claim 1 , wherein b comprises regularly determining at least one position of the portable marking system.

19 . The method of claim 5 , including using at least 25 markers for marking the at least one determined position.

20 . The method as claimed in claim 2 , including determining at least two positions and/or a position range of the marking system in parallel.
