When the barrier member 12 is raised to a sufficient height, the foot 60 extends out of the opening in the barrier member 12 and over the guide rail 28 under the biasing action of the spring 58.

This locks or secures the barrier member 12 in the extended condition since the tongue 70 engaging in the notch 68 locks the locking member 52 since it prevents the locking member 52 from pivoting. This in turn prevents the foot 60 from being drawn back into the barrier member 12.

Abstract

La présente invention concerne un bollard de sécurité (1) constitué d'un élément d'arrêt (12) pouvant sortir et rentrer dans un logement (14). Un organe de verrouillage (52) est monté sur pivot à l'intérieur de l'élément d'arrêt (12). L'organe de verrouillage (52) comporte un pied (60) maintenant l'élément d'arrêt (12) en position sortie. Un verrou (52) permet de bloquer l'organe de verrouillage (52) par rapport au mouvement de pivotement pour que l'élément d'arrêt (12) reste bloqué en position 'sorti'. Selon une autre réalisation, le boîtier est remplacé par un plateau ascenseur (104) servant de support à l'élément d'arrêt (12). Le pied de l'élément d'arrêt (52) est en contact avec le plateau ascenseur (104) et peut se verrouiller en position de façon que l'élément d'arrêt (21) soit verrouillé en position 'dressé'.
