Anchored safety barrier

Abstract

A barrier system located between an access area such as a road and an adjoining hazard has barrier elements mounted on posts secured to inwardly directed, buried and anchored beam members, which extend below the surface of the access area. The posts may be cantilevered from the beams, with bracing means connecting the system members. The post, beam and its anchor members may be pivotally linked, so as to be foldable. The beam anchor may be a cable connected beneath the road to an oppositely located beam and post. The posts can project below the beam support means, and can have stabilizing blades near their lower ends. Posts can be made withdrawable, and can be cross-braced to adjacent posts.

1 . A barrier system for use between an access area and an adjacent environmental hazard, said system having elongated barrier elements supported upon upstanding posts, wherein said posts are each individually secured to post support means, each support means having an inwardly directed beam member extending beneath the surface of said access area, to retain said posts in predetermined, positioned relation with said access area. 
   
   
       2 . The barrier system as set forth in  claim 1 , including anchor means located beneath said surface and secured to said beam member, to secure said beam member substantially immovable. 
   
   
       3 . The barrier system as set forth in  claim 1 , wherein said post is in cantilevered, substantially rigid secured relation with and extending upwardly substantially at right-angles from said beam. 
   
   
       4 . The barrier system as set forth in  claim 3 , including bracing means extending between said post and said beam member. 
   
   
       5 . The barrier system as set forth in  claim 2 , wherein said anchor means extends substantially at right-angles from said beam member. 
   
   
       6 . The barrier system as set forth in  claim 2 , wherein said anchor means extends substantially at right-angles from said beam member, and is substantially parallel with the surface of said area. 
   
   
       7 . The barrier system as set forth in  claim 5 , including bracing means extending between said beam and said anchor means. 
   
   
       8 . The barrier system as set forth in  claim 1 , wherein said beam member is buried beneath the surface of said access area at a substantially predetermined depth. 
   
   
       9 . The barrier system as set forth in  claim 7 , wherein said beam and said beam/anchor bracing means are buried beneath the surface of said access area at a substantially predetermined depth. 
   
   
       10 . The barrier system as set forth in  claim 2 , wherein said anchor means comprises a second upstanding post and second support means, and cable means connected in load transfer relation between said support means and said second support means. 
   
   
       11 . The barrier means as set forth in  claim 1 , wherein said post extends downwardly below said support means. 
   
   
       12 . The barrier means as set forth in  claim 10 , said post including stabilizing blade means located near the post lower end. 
   
   
       13 . The barrier means as set forth in  claim 1 , wherein said posts are withdrawably attached to said post support means. 
   
   
       14 . The barrier means as set forth in  claim 13 , wherein said posts include stop means to provide predetermined vertical positioning of said posts relative to said support means. 
   
   
       15 . The barrier means as set forth in  claim 13 , the outer end of said post support means having a recess to receive said post in entered, secured relation therein. 
   
   
       16 . The barrier means as set forth in  claim 15 , having a beam member of said post support means with top and bottom plate portions of the beam removed, whereby the remaining beam sides form a slotted recess to receive the post in pinned relation to the beam. 
   
   
       17 . The barrier means as set forth in  claim 1 , including inclined cross-bracing means connecting an upper end portion of one said post with a lower connection point of an adjacent said post. 
   
   
       18 . The barrier means as set forth in  claim 17 , having a plurality of said posts with said elongated barrier elements supported therebetween; and having said inclined cross bracing means supporting all intermediate ones of said posts in two-directional braced relation, with the outermost ones of said posts braced outwardly to ground-anchor means.
