Abstract:
1. A bollard assembly comprising a housing part containing a hollow bollard part mounted therein to be slidingly moveable relative to the housing part, and an actuator part arranged within the hollow of the bollard part to urge the bollard part to move relative to the housing part from: a refracted state unsupported by the actuator in which at least some of the length of the bollard part resides within the housing part, to an extended state supported by the actuator part in which relatively less of the length of the bollard part resides within the housing part and relatively more of said length extends beyond the housing part; and, a fixed stop part extending in to the hollow of the bollard part between the head of the bollard part and the actuator part; and, a detachable interface part arranged within the hollow of the bollard part between the stop part and the actuator part to abut the stop part and to be abutted by the actuator part to permit the actuator part via the interface part to support the bollard part at the stop part in the extended state; wherein the actuator part is operable to disengage from the interface part when the bollard part is in the retracted state to permit the interface part to separate from the stop part to be detached therefrom to enable access to the actuator part within the hollow of the bollard part.
