A safety brake apparatus for a vehicle traveling in an elevator hoistway is provided, comprising a first link (52), a pair of second links (54), a connector rod (56), and an intermediate link (58). The first link is pivotally attached to a first side member of the vehicle. The connecting rod extends through the first and second side members, pivotally mounted within each side member. One of the second links is fixed to the connecting rod on the first side member side of the vehicle and the other second link is fixed to the connecting rod on the second side member side of the vehicle. The intermediate link is pivotally attached to both the first and second links on the first side member side of the counterweight. Each second link is connected to a safety brake. Actuating the first link causes the intermediate link to rotate the second links and therefore the connector rod, and causes the second links to actuate the respective safety brake.
Un frein de sécurité, conçu pour un véhicule transporté dans un compartiment d'ascenseur, comprend une première articulation (52), une paire de secondes articulations (54), une tige de raccordement (56) et une articulation intermédiaire (58). La première articulation est fixée pivotante à un premier élément latéral du véhicule. La tige de raccordement s'étend dans les premier et second éléments latéraux, montée pivotante dans le premier élément latéral. Une des secondes articulations est fixée à la tige de raccordement sur le côté du second élément latéral du véhicule. L'articulation intermédiaire est fixée pivotante aux première et seconde articulations se trouvant sur le côté du premier élément latéral du contrepoids. Chaque seconde articulation est raccordée à un frein de sécurité. Par l'actionnement de la première articulation, l'articulation intermédiaire fait tourner les secondes articulations et, par conséquent, la tige de raccordement, et les secondes articulations actionnent le frein de sécurité respectif.
