Abstract

Une ancre pliable comprend une tige (1) possedant des pivots perpendiculaires (A et B) aux extremites opposees. Le pivot (A) supporte les bras (2) et le pivot (B) supporte les bras de jas (5). Les paires de bras peuvent se replier contre la tige ou etre ouverts dans une position de fonctionnement. Les attaches de levier (4A et 4B) peuvent coulisser le long de la tige et s'y accrocher (par une action surcentrique) pour maintenir les bras dans la position de fonctionnement. Des realisations alternatives decrites presentent une ancre dans laquelle une des paires de bras est montee a mi chemin le long de la tige ainsi que des ancres dans lesquelles des anneaux (maintenus en position par des ergots passant au travers de la tige) ou des chaines detachables sont utilises pour maintenir les bras dans les positions ouverte et fermee. L'ancre pliee est stockee a l'interieur d'un tube qui peut etre monte de maniere rotative pour faciliter l'enroulement du cable d'ancre autour de celui-ci.
