Title (EN) IMPROVEMENTS IN AND RELATING TO BOLLARDS
(FR) AMÉLIORATIONS DANS DES BOLLARDS ET ASSOCIÉES À CEUX-CI
Abstract:
(EN) A bollard apparatus comprising an outer bollard member (3) comprising a bore, an inner bollard member (5) at least a part of which is located within said bore and is moveable along the bore from a retracted state in which at least some of the inner bollard member is located within the bore to an extended state in which less of the inner bollard member is located within the bore. At least one urging member (19) is arranged to exert an urging force upon the inner bollard member to urge the inner bollard member towards the extended state. A lifting apparatus (12) is coupled to the inner bollard member and operable to exert a lifting force thereupon sufficient to lift the inner bollard to the extended state when also subject to the urging force.
(FR) L'invention porte sur un appareil de bollard, lequel appareil comprend un élément de bollard externe (3) comprenant un perçage, un élément de bollard interne (5) dont au moins une partie est disposée à l'intérieur dudit perçage et est mobile le long du perçage à partir d'un état rétracté dans lequel au moins une partie de l'élément de bollard interne est disposée à l'intérieur du perçage jusqu'à un état étendu dans lequel une moins grande partie de l'élément de bollard interne est disposée à l'intérieur du perçage. Au moins un élément de poussée (19) est agencé de façon à exercer une force de poussée sur l'élément de bollard interne, de façon à pousser l'élément de bollard interne vers l'état étendu. Un appareil d'élévation (12) est couplé à l'élément de bollards interne et peut fonctionner de façon à exercer une force d'élévation sur celui-ci, suffisante pour élever le bollard interne jusqu'à l'état étendu tout en étant également soumis à la force de poussée.
