Abstract: Security barrier apparatus (10) comprising a support (12, 14) and a barrier member (18, 20) movable relative to the support between a stowed position and a deployed position, the support (12, 14) having an upper part (16) for positioning substantially at ground level. The barrier member (18, 20) has at least two telescopic posts one within the other, the inner post (20) being lowermost in the deployed position. A linkage is provided between an outer post (18) and the inner post (20). In use, motion of the outer post (18) between the stowed position and the deployed position causes corresponding motion of the inner post (20).

Abstract: 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.

Abstract: The invention relates to a security barrier, and a method for operation thereof. The security barrier (10) comprising a support (12) and a barrier member (30) movable relative to the support between a stowed position and a deployed position. The support (12) having an upper part (22) for positioning substantially at ground level (106). The barrier member (30) being rotatably mounted relative to the support (12) such that an axis of rotation (76) of the barrier member (30) is above the upper part (22).
