Bollard for car parks, fences, etc. has connector part between anchoring sleeve and upper part, locked in place by clamping cones tightened by special tool

摘要

The bollard consists of a foundation sleeve imbedded flush in concrete in the ground, and an upper part fastened to it. A connection part (2) between sleeve (1) and upper part (3) is connected bayonet-like to the sleeve. The connection part has a cross bore (11) with conical wider ends (12), which are continued in opposite conical bores (10) of the upper part, and each contain a clamping cone (4,5). Screws (6) in the clamping cones are tightened by a special tool to lock the connector positively within the bayonet lock (8,9), and so lock the upper part to the sleeve.
