Security barrier for forcing vehicles to a stop

Abstract

The invention relates to a security barrier for stopping a vehicle, comprising a base ( 2 ) which is designed to lie on the ground, a frame ( 3 ) which extends above the base ( 2 ) and is designed to absorb the impact of the vehicle, and a pair of loading structures ( 4 ) which are designed to connect the frame ( 3 ) to the base, wherein each loading structure ( 4 ) comprises a spur ( 14 ) which is designed to contact the ground from the side opposite the impact of the vehicle and which is connected to the base ( 2 ) by means of at least one hinge ( 22 ) that has an axis (A), said axis sliding relative to the loading structure ( 4 ) in a direction which is inclined downwards from the frame ( 3 ) to the spur ( 14 ).

1 . A security barrier for stopping a vehicle, comprising
 a base plate which is configured to lie on the ground,   a frame which extends above the base plate and is configured to absorb the impact of the vehicle, and   a pair of load structures which are configured to connect the frame to the base plate,   wherein each load structure comprises a spur which is configured for contacting the ground on the opposite side to the impact of the vehicle and is connected to the base plate by means of at least one hinge which has an axis which, in relation to the load structure, slides in a downwardly inclined direction from the frame ( 3 ) to the spur.   
     
     
         2 . The security barrier according to  claim 1 , wherein the frame comprises:
 a pair of lateral vertical bars which have a lower end which lies on the base plate or is positioned in the vicinity thereof,   at least one upper transverse bar which is connected to the upper ends of the vertical bars or is located in the vicinity thereof, and   a lower transverse bar which is connected to the lower ends of the vertical bars or is located in the vicinity thereof.   
     
     
         3 . The security barrier according to  claim 1 , wherein the hinge comprises a pin which slides along an inclined rail of the associated load structure. 
     
     
         4 . The security barrier according to  claim 3 , wherein each delimiting structure has:
 a first sloping bar which defines the rail, and   a second sloping bar;   wherein the first sloping bar is connected to the vertical bar in the vicinity of the lower end, and   wherein the second sloping bar is connected to an upper end of the vertical bar or to an end of the upper transverse bar,   wherein the first and the second sloping bar converge with one another to the spur.   
     
     
         5 . The security barrier according to  claim 1 , wherein compression rods are present, which compression rods extend forwards or upwards from upper ends of vertical bars and which are connected together at their ends by a transverse bar. 
     
     
         6 . The security barrier according to  claim 1 , wherein the base plate has a lower surface with increased friction. 
     
     
         7 . The security barrier according to  claim 6 , wherein the lower surface is defined by a coating of elastomeric material. 
     
     
         8 . The security barrier according to  claim 6 , wherein the lower surface has elevations which are configured to increase its adhesion to the ground. 
     
     
         9 . The security barrier according to  claim 1 , wherein the security barrier is provided with a bicycle rack. 
     
     
         10 . The security barrier according to  claim 1 , further comprising a tank. 
     
     
         11 . The security barrier according to  claim 1 , further comprising a container which is filled with stones or other heavy material. 
     
     
         12 . The security barrier according to  claim 1 , wherein the load structures are connected to the base plate by means of two hinges which have respective axes which extend parallel to one another and slide in the inclined direction relative to the load structure. 
     
     
         13 . The security barrier according to  claim 12 , wherein the frame is raised relative to the base plate. 
     
     
         14 . The security barrier according to  claim 1 , wherein at least one auxiliary load structure mounted on the base plate is provided between the pair of load structures. 
     
     
         15 . A security barrier system comprising a plurality of security barriers according to  claim 1 , in which security barriers are coupled with one another.
