The invention relates to a security barrier apparatus (10, 70, 100) comprising a support (12) having at least three upright posts (14, 16, 18, 72) thereon. Two of the posts (14, 18) being fixed to the support (12) and at least one post (16, 72) being translatably movable relative to the two fixed posts (14, 18). The two fixed posts (14, 18) being spaced apart from one another and comprise a first plane (19) therebetween. The movable post (16, 72) being mounted to a slide device (24) of the support (12) for providing said translatable movement. The slide device (24) to operate the apparatus (10, 70) between an open position and a closed position such that in the closed position the movable post (16, 72) is between the fixed posts (14, 18) for inhibiting the passage of a vehicle, and in the open position the movable post (16, 72) is out of alignment with the first plane (19) and adjacent to one of the fixed posts (14, 18) for allowing the passage of a vehicle therebetween. |

1. A security barrier apparatus, comprising a support having at least three upright posts thereon, two of the posts being fixed to the support and at least one post being translatably movable relative to the two fixed posts, the two fixed posts being spaced apart from one another and defining a first plane therebetween, the movable post being mounted to a slide device of the support for providing said translatable movement, wherein the slide device includes a belt or track to operate the movable post, the belt or track being arranged to move in a horizontal plane to operate the apparatus between an open position and a closed position such that in the closed position the movable post is between the fixed posts for inhibiting the passage of a vehicle, and in the open position the movable post is out of alignment with the first plane and adjacent to one of the fixed posts for allowing the passage of a vehicle therebetween. |
