PCT No. PCT/FR93/00013 Sec. 371 Date Sep. 23, 1994 Sec. 102(e) Date Sep. 23, 1994 PCT Filed Jan. 8, 1993 PCT Pub. No. WO93/14272 PCT Pub. Date Jul. 22, 1993.The invention relates to a self-contained bollard device of variable height for dispensing electricity supplies or various fluids, the device comprising vertically movable equipment, supporting a bollard, which contains a co-axial rotary shutter. Rotation of the shutter, which is controlled by a lock with pins, presents a dispensing surface to the user or closes the window of the bollard. A single wrench-type key controls holding of the bollard in the raised or lowered positions, and also rotation of the shutter, by means of two identical locks. The bollard includes safety devices, in particular to interrupt the electricity supply when the shutter starts to rotate or the bollard starts to descend, and also in the event of a shock. The field of the invention is that of street furniture, and in particular for equipping places open to the public, such as marketplaces, camping sites, quays or piers, and service stations.
