Modular crash barrier system

Abstract

The present invention relates to a modular crash barrier system for impact absorption. The system comprises at least one post having a longitudinal direction, said at least one post being elastically deformable, said at least one post comprising at least one attachment groove defined by an inner wall and a first and a second side wall, said at least one attachment groove extending in said longitudinal direction. The system further comprises a protrusion arranged in said at least one attachment groove and connected to said inner wall, said protrusion having an extension along said longitudinal direction, at least one transverse barrier element comprising at least one attachment element slideably arrangeable within said at least one attachment groove for engagement with the protrusion, and wherein said inner wall, in an assembled state of the modular crash barrier system, is more prone to deformation than said first and second side wall in response to a force applied to said at least one post and caused by an impact to the transverse barrier element.

1 . A modular crash barrier system for impact absorption comprising:
 at least one post having a longitudinal direction, said at least one post being elastically deformable, said at least one post comprising at least one attachment groove defined by an inner wall and a first and a second side wall, said at least one attachment groove extending in said longitudinal direction;   a protrusion arranged in said at least one attachment groove and connected to said inner wall, said protrusion having an extension along said longitudinal direction;   at least one transverse barrier element comprising at least one attachment element slideably arrangeable within said at least one attachment groove for engagement with the protrusion;   wherein said inner wall, in an assembled state of the modular crash barrier system, is more prone to deformation than said first and second side wall in response to a force applied to said at least one post and caused by an impact to the transverse barrier element.   
     
     
         2 . The system according to  claim 1 , wherein the at least one attachment element has a shape and size substantially corresponds to the shape and size of the at least one attachment groove. 
     
     
         3 . The system according to  claim 1 , wherein said system comprises a first post and a second post, wherein each of said first and said second post comprises at least one attachment groove,
 wherein said at least one transverse barrier element comprises a first attachment element and a second attachment element, and   wherein said first attachment element is arranged at a predetermined height within said at least one attachment groove of said first post and wherein said second attachment element is arranged at a predetermined height within said at least one attachment groove of said second post such that said at least one transverse barrier element is arranged between said first and said second post at a predetermined height.   
     
     
         4 . The system according to  claim 1 , further comprising at least one spacer element slideably arrangeable within said at least one attachment groove. 
     
     
         5 . The system according to  claim 4 , wherein all portions of said at least one attachment groove not occupied by said at least one attachment element, in said assembled state, is occupied by said at least one spacer element. 
     
     
         6 . The system according to  claim 1 , wherein a transverse direction of said transverse barrier element is substantially perpendicular to said longitudinal direction of said post when said at least one attachment element is arranged within said at least one attachment groove of said at least one post. 
     
     
         7 . The system according to  claim 1 , wherein said protrusion has an extension perpendicular to said longitudinal direction, wherein a cross-section of said protrusion at a first end portion thereof has a width smaller than a cross-section of said protrusion at a second end portion thereof, wherein the second end portion is more distal to the inner wall of the at least one attachment groove than the first end portion. 
     
     
         8 . The system according to  claim 7 , wherein said at least one protrusion has a mushroom-shaped cross-section across said transverse extension of said at least one protrusion. 
     
     
         9 . The system according to  claim 8 , wherein the mushroom-shaped cross-section comprises two undercut engagement surfaces facing the inner wall. 
     
     
         10 . The system according to  claim 5 , wherein said at least one attachment element comprises at least two attachment portions, and wherein said at least two attachment portions are slideably arrangeable within a respective one of a first and second subgroove of the attachment groove separated by the protrusion. 
     
     
         11 . The system according to  claim 1 , further comprising a rigid core element configured to support said at least one post.
