PCT No. PCT/DE85/00518 Sec. 371 Date Aug. 12, 1986 Sec. 102(e) Date Aug. 12, 1986 PCT Filed Dec. 10, 1985 PCT Pub. No. WO86/03531 PCT Pub. Date Jun. 19, 1986.For the temporary blocking of the access to parking places, driveways and access roads a post is used, which is anchored in the ground and is foldable about an articulation arranged over the ground, whereby a drive is located in the post which can be activated over a receiver in correspondence with a portable emitter. Thereby, the post is suitably built as a hollow body, so that the drive and the remaining parts can be safely lodged therein. This way, the barrier post can be remote-controlled without difficulty from an approaching vehicle by means of a portable emitter, or for instance in the case of blocking the access to football stadiums, from a control center.
