Retractable marker disc for road traffic with spike-protected Reflectors

However, the above glass reflectors are also used in these devices touched and damaged at the same time by the spiked tires. All of the previously described iMarking Bodies were either built into the roadway or glued using adhesives. These articles were mostly glued only for construction site markings, but occasionally also for Permanent markings. The difficulties of permanent marking by gluing metal bodies or plastic bodies on the carriageways lie in the fact that £ Grs3 £ sflSch # n between the marker body-n and the adhesive with each other do not stick firmly enough. Audi undercuts and Cones on the marker bodies only solved this problem insufficient. Especially since bonding plastic bodies to concrete or black ceilings is difficult at all, especially home plastic polyethylene, which is mainly used as a manufacturing material serves. A useful bonding option for such materials were identified with the German utility model D 3> 4 785/19 e. This is followed by adhesive anchoring preferably with grid-shaped bottom parts, (7) where the glue can flow around the bars.

The invention now combines known possibilities of anchoring with a solution to protect the reflectors from damage. According to the invention, one is assembled from several parts Marking disc constructed in such a way that a base made of metal or plastic has a grid shape on its bottom surface Has. The body can be round, polygonal, rectangular or even be oval in shape, as well as multicolored in itself through subdivision be composed of the body. An exemplary embodiment is shown in the drawing.

In the lower part (1) is an upper part (2), which as required laterally provided with reflectors (3) is used. This top (2) protrudes with the reflectors (j5) over the upper surface of the Lower part. Here, inclined, ramp-like projections (4) cause lateral sliding interlocking with the lower part (.1).

If the marker body is driven over, the vehicle tire first touches the inclined projections (4) and thus forces the upper part (2) to dive into the corresponding recess in the lower part, (l). Here, the reflectors (2) touch a rubber strip (5) or plastic strip of appropriate elasticity on the end faces, whereby the reflectors clean themselves. In addition to the protective effect against contact with the spike, which is achieved by the inclined projections of the upper part, there is also self-cleaning, as was previously known in a similar form. (I9e / 6.3O No. 66 " 4 * 3 v. 29.II.36) A suspension (6) inserted in the lower part acts against the pressure of the KPZ tire. This can either be an air cushion or foam rubber part or a combination thereof consist of spring parts or only one spring. However, a corrosion-resistant spring in a rubber cap that is open at the bottom is preferably used. The air cushion enclosed in this rubber cap prevents water from getting into the rubber cap. As this cap takes up the entire space (8) of the Fills the recess in the lower part fairly, this also prevents damage to the marker body by ice formation in winter.

The laying of the marker body in the form described takes place by gluing on the road surface. A hot melt adhesive or another suitable adhesive can be used for this purpose. whose nature is suitable to flow through the grid parts (7) on the underside. However, the lower part can also be attached to the upper Page be made flat. Then the lower part can be installed flat in the road surface. Then only the one protrudes over the road surface movable reflector part addition. With this solution, a bump-free Marking done with a floor reflector. This becomes one remedied the major disadvantage of the previous designs of floor reflectors. The entire surface of the lower part serves with its upper side as a marking element which lies flat in the road surface.

The reflector protrudes somewhat above the surface, but since it dips away when sowing at the bottom, it does not form an obstacle on the fan. This makes it possible for the first time to use floor reflectors even in snowy areas that have to reckon with the use of snow clearing.
