Device and method for marking indicia on terrestrial surfaces in topographical surveying

A device for marking indicia on a terrestrial surface implemented in topographical surveying comprises:

• (a) a support element terminating with essentially pointed tip, defining a centerline of said indicia marking device,
• said support element is operationally connectable to a topographic surveying instrument configured for determining geographical coordinates;
• (b) at least one holder, mountable onto said support element, configured to accommodate a paint container;
• (c) at least one pre-pressurized paint container, comprising a discharge nozzle configured to controllably discharge a stream of a paint from said at least one pre-pressurized paint container;
• (d) an actuator configured for manipulating said discharge nozzle of said at least one pre-pressurized paint container, to dispense said stream of said paint from said at least one pre-pressurized paint container;
• (e) at least one swinging nozzle comprising a bottom end from which said paint is discharged and a top portion operationally connectable to said support element, wherein said top portion of said at least one swinging nozzle forms a hinged connection with said support element, and wherein said bottom end of said at least one swinging nozzle is configured to move away and towards said centerline of said support element;
• wherein said at least one swinging nozzle is configured to reversibly assume:
• (I) a convergent configuration, in which said bottom end of said at least one swinging nozzle is disposed essentially alongside said centerline;
• or
• (II) a divergent configuration, in which said bottom end of said at least one swinging nozzle is disposed essentially offset said centerline;
• (f) at least one driving mechanism selected from the group consisting of:
• (I) a pushing mechanism;
• and
• (II) a pulling mechanism;
• wherein said at least one driving mechanism is configured for driving said at least one swinging nozzle between said divergent configuration and said convergent configuration;
• (g) at least one outlet disposed at a terminal portion of said at least one swinging nozzle, operationally connectable to said discharge nozzle of said at least one pre-pressurized paint container, configured to dispense said paint from said at least one pre-pressurized paint container on a terrestrial surface, to mark a desired indicium thereon related to the terrestrial surface adjacent to said essentially pointed tip.
