Abstract

La présente invention a pour but d'assurer qu'un mécanisme de liaison et un mécanisme de rochet sont couplés de manière fiable dans un régulateur qui peut maintenir un état dans lequel le mécanisme de liaison et un poids de cliquet sont indépendants. Pour atteindre ce but, l'invention porte sur un régulateur d'ascenseur qui comprend : un mécanisme de rochet (204), qui comporte une pluralité de points d'action de cliquet (204a) qui viennent en prise avec une masselotte (202) ; un disque (205), qui est intégré au mécanisme de rochet (204) et qui comprend une unité de mise en prise (209) avec laquelle vient en prise un premier mécanisme de liaison (206). Le disque (205) possède une partie formée de prévention de couplage (301) qui empêche le premier mécanisme de liaison (206) de se trouver dans une orientation dans laquelle le premier mécanisme de liaison (206) peut se coupler avec un poids de cliquet (207) quand le premier mécanisme de liaison (206) n'est pas dans une position pour venir en prise avec l'unité de prise (209).
