Patent

CA 2482465

A belay device for climbing with at least one rope is provided. The belay device comprises a first plate having a first lobe with the rope wrapping at least partially about the first lobe and a second plate having a second lobe. A connection mechanism connects the first plate to the second plate through a rotation point with the rotation point positioned inside the second lobe. A first channel is defined by the first plate and the first lobe and the second plate and the second lobe with the rope moveable through the first channel wherein tension on the rope rotates the first plate and the second plate relative to each other thereby narrowing the first channel and impeding movement of the rope through the first channel.

L'invention concerne un dispositif d'assurage pour l'escalade, comportant au moins une corde. Ce dispositif comprend une première plaque à premier lobe, la corde s'enroulant au moins en partie autour du premier lobe, et une seconde plaque à second lobe. Un mécanisme de liaison relie les première et seconde plaques, via un point de rotation placé dans le second lobe. Un premier canal est défini par la première plaque et le premier lobe et par la seconde plaque et le second lobe, la corde se déplaçant dans ce premier canal, et une tension de cette corde mettant en rotation les deux plaques l'une par rapport à l'autre pour rétrécir ledit premier canal et empêcher tout mouvement de la corde à travers le canal en question.
