Definitions

  • the present invention relates to protective structures which are arranged on road sides to prevent accidental exit of vehicles, particularly the structures of that type provide added protection for motorcyclists.
  • VCS vehicle containment systems for containing vehicles on roads
  • P Circular Order 321/95 T and P. It includes a specific motorcyclist protective system.
  • Circular Order 18/2004 establishes criteria for using motorcyclist protective systems in addition to defining a system developed by the Directorate General of Roads which proposes the use of structures which ensure that the motorcyclists are not able to go beyond the protective barrier upon sliding on the pavement during an accident as a preferred solution.
  • the lower complementary screen is attached by means of anchoring supports on the support posts of the structure and anchoring supports on the upper rail, said anchoring supports determining certain flexibility for absorbing the collision impacts against said complementary screen.
  • EP 1,184,515 and EP 1,182,296 disclose protective structures of this type formed by an upper rail fixed to support posts through several parts known as barriers, a lower screen attached by means of anchoring supports on the support posts of the structure being arranged therebelow, making use of the set screws typical of the upper rail on said support posts.
  • the drawback of this embodiment is that in order to assemble the lower screen it is necessary to loosen the securing anchors of the upper rail making the assembly difficult.
  • Spanish patent P200900337 belonging to the same applicant as the present invention contemplates the production of a protective structure of that type with the lower screen anchored on the upper rail with flexible parts made of sheet metal and on the support posts of the structure by means of other flexible parts of sheet metal which are fixed on the support posts regardless of the anchoring of the upper rail.
  • This solution allows a simple and fast assembly of the lower screen since it does not require loosening the anchoring of the upper rail.
  • the invention proposes improvements in the mentioned road side protective structures incorporating an upper rail and a lower screen determining structural features which allow the assembly of the lower screen regardless of the anchoring of the upper rail on the posts, and which further establish a lower screen shock-absorbing arrangement in advantageous effectiveness and safety conditions.
  • the lower screen of the protective structure is attached on the upper rail which is supported by structural support posts by means of anchoring arms comprising a rigid profile section which is attached by one end directly on the upper rail, incorporating at said end an angular plate providing a second support on the mentioned upper rail, whereas said rigid profile section incorporates a J-shaped part at the other end establishing attachment on the lower screen.
  • This assembly arrangement of the lower screen determines conditions for attaching said screen making it flexible in a backwards direction when receiving a frontal impact but in a manner such that the flexibility decreases as the deformation progresses backwards, whereby said screen has a very affective impact absorption capacity in the first phase of backwards deformation, but as the deformation progresses the flexibility decreases, preventing motorcyclists from being able to pass below the protective structure in the event of an accident in which they slide on the pavement.
  • the anchoring arms between the lower screen and the upper rail can be one-piece, the end parts being determined as extensions from the ends of the rigid profile section, or the rigid profile section and the end parts can be independent parts anchored to one another, the rigid profile section may be in this case a section of the same profile as the support posts of the protective structure whereby a cheaper embodiment of the assembly of the protective structure is produced.
  • Parts made of bent sheet with a U-shaped part from which an extension determining two successive sloping bends protrude outwards from one side are further arranged between the lower screen and the posts supporting the upper rail.
  • said parts are anchored on the lower screen of the protective structure by means of the side extension, or on the supporting assembly of the upper rail by means of the U-shaped part such that anchoring is only established in one of the parts, whereas support without anchoring which favors the elasticity of the assembly of the lower screen is established on the other part.
  • these parts intercalated between the lower screen and the support posts of the structure can also be anchored to the two parts.
  • the improvements of the invention determine very advantageous features, the embodiment of the protective structure with said improvements acquiring its own identity and preferential nature with respect to the known protective structures of the same function.
  • the object of the invention relates to a road side protective structure of the type comprising an upper rail (1) attached by means of barriers (2) on support posts (3) staked in the ground, a lower screen (4) passing under said upper rail (1) closing the gap from the protection to the ground to prevent motorcyclists involved in an accident sliding on the road pavement from being able to pass under the protection.
  • Both the upper rail (1) and the lower screen (4) are made of sheet metal with a corrugated-shaped cross section providing rigidity, according to any conventional embodiment of the rails which are used in the road side protections; where the support posts (3) are made up of tubular "C" shaped metal profiles, or any other conventional section of the support posts of the protective structures of this type.
  • the lower screen (4) is attached on the upper rail (1) by means of arms (5) comprising a rigid profile section (6) which is attached at one end directly on the upper rail (1), whereas it is attached at the other end on the lower screen (4) by means of a J-shaped part (7), as seen in Figure 3 .
  • the rigid profile section (6) further incorporates an angular part (8) establishing a second support on the mentioned upper rail (1), as seen in the same Figure 3 .
  • the structural assembly of the mentioned arms (5) can be of a single part, the part (7) being J-shaped and the angular part (8) being formed as end extensions of the rigid profile section (6); but in a preferred manner an embodiment with the three parts formed by independent parts is provided, the rigid profile section (6) may be in this case a section of the same profile as the support posts (3) of the structure, said rigid profile section (6) having a slit (9) for anchoring the J-shaped part (7), thus allowing the regulation of the attachment height of the lower screen (4) as deemed appropriate.
  • any of the end parts (7, 8) can be formed as an extension of the rigid profile section (6) and the other can be an independent part.
  • the lower screen (4) is supported by means of parts (10) made of bent sheet which determine ( Figures 4 and 5 ) a U-shaped part (10.1) from which an extension (10.2) determining two successive sloping bends protrude outwards from one side.
  • said parts (10) are anchored on the lower screen (4) or on the structural assembly of the support posts (3), being supported without anchoring on the other part in each of the cases, i.e., in this case, non-anchoring support is established between the lower screen (4) and the support posts (3) by means of those parts (10), thus determining a very flexible elastic play between both parts.
  • said parts (10) can be anchored on the lower screen (4) and on the structural assembly of the support posts (3).
  • the mentioned parts (10) are attached on the lower screen (4) by means of the extension (10.2) through a slit (11) which allows regulating the height, whereas they are supported, but without anchoring, with the U-shaped part (10.1) on the support posts (3) of the structure, as seen in Figure 2 .
  • the arrangement can also be a reverse arrangement, i.e., anchoring of the U-shaped part (10.1) on the structural assembly of the support posts (3) and with the extension (10.2) anchored on the lower screen (4).
