Post

Abstract

A post is provided which includes apertures on alternate sides of the post which, in use, receive and retain at least one cable therein, the same number of apertures are on each side of the post wherein each aperture: has a side opening in the form of a mouth, wherein the mouth is at a distal region thereof configured to have a top surface with an angle greater than the angle at a proximate region of the mouth so as to reduce the travel path of, and/or; any frictional contact with; the cable, during ejection from aperture following a collision.

What we claim is: 
     
       1. A road barrier post, comprising:
 at least one aperture on alternate sides of the post which, in use, each receives and retains at least one cable therein, wherein each aperture includes: 
 a top edge extending from a side of the post to each aperture, 
 wherein the top edge comprises a distal linear surface and a proximal linear surface, said distal linear surface extending to the side of the post and forming a quick cable release portion, and said proximal linear surface forming the remainder of the top edge, the proximal linear surface extending from the distal linear surface toward a longitudinal axis of the post, and 
 wherein the distal linear surface comprises a first angle relative to a horizontal line transverse to the longitudinal axis, that is greater than a second angle of the proximal linear surface relative to the horizontal line, wherein the first angle and the second angle are positive non-zero angles so as to reduce: 
 the travel path of or; 
 any frictional contact with; 
 the at least one cable during ejection from the aperture following a collision by a vehicle. 
 
     
     
       2. The post as claimed in  claim 1 , wherein in use, the post is hollow and includes a cap that fits seamlessly over the open-ended top of the post and at least one elongated appendage extending from the cap and substantially inside the post, wherein the cap and appendage are integrally formed as a single piece. 
     
     
       3. A barrier which includes a post as claimed in  claim 1  together with a plurality of cables supported in the apertures of the post.
