Description

The innovation relates to a road marker according to the preamble of the protection claim. 1

Road markers and road markings fulfill a multitude of tasks. In particular, they improve orientation on traffic areas and create safe traffic routing.

Road markers are already known from the prior art. For example, Holophane Cryzal of France offers road markers of tempered glass with a retroreflective marking head. For installation, a hole is drilled in the pavement using a core drill and then the pavement marker is attached using a 2-component adhesive. When installed, the road marker is approximately 12 mm above the road surface. The supernatant results in particular in the disadvantage that, for example, a snow blade of a snowplow causes severe damage to the marker. In addition, the projection of the marker is a danger for cyclists, as they can fall because of the uneven and smooth road surface.

From the prior art, it is also known to arrange a light guide mat in an existing of a curable casting mass light guide. This subject matter is apparent, for example, from that of the same assignee WO 2012/097975 A1 , Likewise, from this document has become known for embedding in the light guide suitable injection molding mat. Reference is made to the disclosure there. This disclosure is fully within the subject of the present disclosure.

In the embodiments of the prior art, the optical fiber mat was always cast in a pourable plastic or in a concrete material. However, both materials are not suitable for this with a vehicle such. B. to overtake a truck. Furthermore, when driving over high loads on the road marker, so it must be completely replaced in case of failure, which is very expensive and expensive.

The novelty is therefore the object of providing a road marker ready, which is stable enough for driving over with a motor vehicle and is flush mounted in the road surface.

To solve the problem, the innovation is characterized by the technical teaching of claim 1.

An essential feature of the innovation is that the road marker consists of a frame and a lid pivotally mounted thereto, wherein the frame and the lid are made of metal and the lid has at least one recess for receiving a light-guiding element of a light-conducting mat.

The innovation according to the invention has the advantage that the finished frame and the cover can be pre-produced and assembly with the light guide mat can take place at the installation site. Due to the easy mounting of the light guide mat, this can also be changed at any time at the installation.

The road marker according to the invention is preferably designed as a caisson made of metal, which results in the advantage that it can be easily integrated in the road surface and also withstands the high loads of road traffic.

Due to the two-part frame-lid construction, the optical fiber mats or individual components thereof can be easily exchanged, whereby the subsequent costs are significantly reduced, since not the entire road marker for the replacement of the light source has to be removed from the road surface.

The light guide mat for the road marker at least partially consists of a light-conducting plastic, wherein light guide elements are formed from an at least partially photoconductive plastic, one end face is formed as a light-emitting surfaces on the top of the road marker (light guide).
