Field of the invention
[0001] The present invention refers to the field of traffic signalling devices, for example
of roadway type, in particular in the form of signalling milestones of alignments
of circulation ways, and similar devices.
Background of the invention
[0002] The prior art includes different solutions of traffic signalling devices of pole
type in general, and of device of milestone type for signalling of alignments in circulation
ways.
[0003] It is known to produce this type of devices in synthetic material, including one
pole part, for example with a general shape of cylindrical type produced by means
of plastic extrusion, and one base part with a general shape of disc type.
[0004] One of the problems associated with this type of devices is respective fixation,
in simple and ergonomic manner to the pavement, by means of reduced cost and providing
a reliable retention.

EP 3150263 A1 discloses an anchor of marker for installation in the snow, and that can be rotationally
fitted under pressure in a hole when the hole has a relatively small diameter.
[0011] There is therefore the need of a traffic signalling pole that provides a simpler
and more reliable fixation of the pole to the pavement.
[0012] Another problem associated with this type of poles is the possibility of they recovering
their initial shape in case of impact thereupon, in particular after being hit by
a vehicle.

particular of milestone type, adapted so that provides a simpler fixation, less laborious
and more reliable to the pavement.

signalling pole according to claim 1, whereby preferred embodiments are disclosed

presents first and second engagement parts on the mutually opposing faces of the pole
and base parts thereof, adapted so that provide reciprocal engagement and, preferentially,
removable blocking of said pole and base parts, by means of one vertical translation
movement and of one rotation movement with relation to an engagement axis.
