Abstract
Abstract This invention relates to safety devices placed on the side of highways, of the barrier, rail or curb type, comprising a continuous strip parallel to the road and exposed to the shocks of the vehicles, intended for retaining the latter, which continuous strip bears a solid or pasty sliding coating, for example a coating of polytetrafluoroethylene or a solid silicone resin, or a layer of a paraffin wax or of micronized graphite, or a layer of grease.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
51 words
A safety device to be implanted along a road to retain vehicles thereon, said device comprising a surface to be exposed to the shocks of vehicles, and said surface bearing a sliding coating comprising a layer of paraffin comprising a solid alkane having a number of carbon atoms greater than 15.
Claim 2
Dependent Claim
51 words
A safety device to be implanted along a road to retain vehicles thereon, said device comprising a surface to be exposed to the shocks of vehicles, and said surface bearing a sliding coating comprising a layer of paraffin comprising a solid alkane having a number of carbon atoms greater than 15.
Claim 3
Dependent Claim
67 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a surface to be exposed to the shocks of vehicles, wherein at least a part of said surface bears a strip of a sliding coating comprising micro-balls having a diameter of less than 3 mm which are fixed by means of a binding agent to said surface.
Claim 4
Dependent Claim
67 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a surface to be exposed to the shocks of vehicles, wherein at least a part of said surface bears a strip of a sliding coating comprising micro-balls having a diameter of less than 3 mm which are fixed by means of a binding agent to said surface.
Claim 5
Dependent Claim
82 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising metallic profiles to be placed end to end along the road to form a continuous surface parallel to the road and which is to be exposed to shocks of vehicles, said surface being upwardly curved and having a convexity to be directed towards the road and bearing a sliding coating, and said surface being adapted to be in contact with the ground.
Claim 6
Dependent Claim
82 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising metallic profiles to be placed end to end along the road to form a continuous surface parallel to the road and which is to be exposed to shocks of vehicles, said surface being upwardly curved and having a convexity to be directed towards the road and bearing a sliding coating, and said surface being adapted to be in contact with the ground.
Claim 7
Dependent Claim
52 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a curb comprising prefabricated concrete elements, wherein said prefabricated concrete elements comprise a horizontal rib having a convex surface to be directed towards the road, which convex surface bears a sliding coating.
Claim 8
Dependent Claim
52 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a curb comprising prefabricated concrete elements, wherein said prefabricated concrete elements comprise a horizontal rib having a convex surface to be directed towards the road, which convex surface bears a sliding coating.
Claim 9
Dependent Claim
60 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a concrete barrier to separate two carriageways of traffic, wherein said barrier comprises, in its upper part, a vertical wall which is capped by tunnel-shaped metallic profiles which mutually overlap and which bear on their outer surfaces a sliding coating.
Claim 10
Dependent Claim
60 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a concrete barrier to separate two carriageways of traffic, wherein said barrier comprises, in its upper part, a vertical wall which is capped by tunnel-shaped metallic profiles which mutually overlap and which bear on their outer surfaces a sliding coating.
Claim 11
Dependent Claim
88 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising safety rails comprising round timber sections assembled end to end to form a horizontal rail, wherein said round timber sections are to be assembled, on the road side, by longitudinal metallic profiles each having a surface to face towards the road, the surfaces bearing a sliding coating, which metallic profiles extend over the whole length of the rail and mutually overlap at the joins between two timber sections.
Claim 12
Dependent Claim
88 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising safety rails comprising round timber sections assembled end to end to form a horizontal rail, wherein said round timber sections are to be assembled, on the road side, by longitudinal metallic profiles each having a surface to face towards the road, the surfaces bearing a sliding coating, which metallic profiles extend over the whole length of the rail and mutually overlap at the joins between two timber sections.
Claim 13
Dependent Claim
71 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a horizontal rail comprising metallic tubes assembled end to end and mounted on posts, each of said tubes having a surface to face towards the road, the surfaces bearing a sliding coating forming a longitudinal strip which is located along the generatrix of the tube to be closest to the road.
Claim 14
Dependent Claim
71 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a horizontal rail comprising metallic tubes assembled end to end and mounted on posts, each of said tubes having a surface to face towards the road, the surfaces bearing a sliding coating forming a longitudinal strip which is located along the generatrix of the tube to be closest to the road.
Claim 15
Dependent Claim
46 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a surface to be exposed to shocks of vehicles, wherein at least a part of said surface bears a sliding coating comprising a solid silicon resin.
Claim 16
Dependent Claim
46 words
A safety device to be implanted along a road to retain vehicles thereon, said device being of the type comprising a surface to be exposed to shocks of vehicles, wherein at least a part of said surface bears a sliding coating comprising a solid silicon resin.
Claim 17
Dependent Claim
21 words
A safety device according to any of claims 1 to 8 wherein said sliding coating is applied directly on said surface.
Claim 18
Dependent Claim
43 words
