Abstract
The present invention relates to a device designed for use with traffic signs and road paving, for providing better road conditions, which comprises an outer framework which can be embedded in the road subgrade, with its top edge flush with the road paving, the outer framework being removably coupled to an inner framework supporting a panel made of a glossy, anti-slipping and wear-resistant material.
Description
- The present invention relates to traffic sign and road paving devices for improving road safety conditions.
- As is known, for making traffic signs, suitable paints are conventionally used to be applied on the road paving.
- Such a solution is affected by several problems since, at first, for applying the mentioned paints and allowing them to be properly dried, it is necessary to interrupt, for comparatively long time periods, the road traffic, i.e. both the pedestrian and vehicle traffics.
- Another important problem affecting prior solutions, is that cyclists and motorcyclists, as well as pedestrians, are subjected to frequent accidents since, by applying several paint layers on already painted road regions, the road surface becomes very slipping.
- The above accidents, in turn, are associated with very high social costs.
- Yet another problem is that prior solutions are very expensive, since it is necessary to perform frequent re-painting operations, since, within few days, the traffic signs become poorly visible and, consequently, constitute a further danger for the road users.
- Accordingly, the aim of the present invention is to overcome the above mentioned problems, by providing traffic sign and road paving devices, allowing the road to always have a glossy and anti-slipping surface, which, in addition, is very resistant to wear, atmospheric agents, as well as to any types of traffic, both pedestrian and vehicle traffic.
- Within the scope of the above mentioned aim, a main object of the present invention is to provide devices requiring a very reduced maintenance.
- Another object of the present is to provide devices which are very advantageous from a mere economic standpoint.
- Another object of the present invention is to provide devices which, upon assembling on a road, can be easily interexchanged in a very quick time, thereby solving all the problems related to the interruption of the traffic which at present affect all of the conventional devices.
- Yet another object of the present invention is to provide traffic sign and road paving devices which can be easily made starting from easily available elements and materials, and which, moreover, are very competitive from a mere economic standpoint.
- According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a traffic sign and paving device, designed for improving road safety conditions, characterized in that said device comprises an outer framework, which can be embedded in a road subgrade, said outer framework having a top edge adapted to be flush arranged with the road paving, said outer framework being removably coupled to an inner framework, supporting a panel made of a glossy, anti-slipping and wear-resistant material.
- Further characteristics and advantages of the present invention will become more apparent hereinafter from the following detailed disclosure of a preferred, though not exclusive, embodiment of traffic sign and road paving devices, for improving road safety conditions, which are illustrated, by way of an indicative, but not limitative example, in the accompanying drawings, where:
