Abstract (en)
[origin: EP0857826A1] The bollard consists of a housing (1) which surrounds the bollard (2) itself and contains a cover with a sleeve (4) for the bollard to slide in. The cover is removable for maintenance purposes. The housing contains a rotary lock (5) which lies parallel to the sleeve and is equipped with a lateral projection (8) which engages with ribs (9,10) projecting from the sleeve to prevent any unauthorised removal of the cover. The lock has a polygonal top (19) which can be turned by a special tool after sliding open a spring-loaded cover (18).
