However, the car-side engagement element 32 is arranged in a state where it is lifted upward by the first link member 41A and the second link member 41B. Therefore, a downward force G1 in the vertical direction is applied to the car-side engagement element 32 by its own weight.
  • first link member 41A that supports the car-side engaging element 32 is restricted by the first stopper 45 from rotating upward in the counterclockwise direction, that is, in the vertical direction.
  • the weight of the locking side hook member 33 also acts to hold the locked state, the urging force F1 of the locking holding member 39 can be reduced, and the locking holding member 39 can be downsized.
  • FIG. 9 is a front view showing the car-side lock mechanism 30 when the car 110 is lowered and accelerated downward.
  • the locking side hook member 33 is acted on by the weight of the locking side hook member 33 in the direction opposite to the release moment M1 shown in FIG. Furthermore, the locking holding member 39 is arranged in a compressed state. Therefore, the locking holding member 39 urges the locking-side hook member 33 downward in the vertical direction by an urging force F2 that is a restoring force generated when compressed.
  • the interval between the rotation shaft 35 and the lock holding member 39 is set longer than the interval between the transmission pin 37 and the rotation shaft 35. Therefore, even if the urging force F2 of the locking holding member 39 is reduced, the moment in the locking direction caused by the urging of the locking holding member 39 is larger than the release moment F4 applied to the transmission pin 37 by the car-side engagement element 32. Can be easily enlarged.
  • the car-side lock mechanism 30 and the building-side lock mechanism 230 are arranged on the door hanger.
  • the present invention is not limited to this, and the car-side lock mechanism and the building-side lock are not limited thereto.
  • only the lock-side hook member 33 and the fixed hook member 34 in the car-side lock mechanism 30 may be arranged on the door hanger, and other members may be provided on the door portion.
  • the locking side hook member 33 and the car side engaging element 32 are connected by a transmission mechanism including a link mechanism, for example, and the operation of the car side engaging element 32 is transmitted to the locking side hook member 33.

Abstract

La présente invention concerne un dispositif d'ascenseur, un mécanisme de verrouillage côté cabine étant doté d'une plaque de support, d'un arbre de pivot, d'un élément crochet côté verrouillage, d'un élément crochet fixe, d'une section de mise en prise côté cabine, d'un élément de liaison, d'un élément de transmission et d'un élément de maintien de verrouillage. L'élément de maintien de verrouillage presse l'élément crochet côté verrouillage dans la direction dans laquelle l'élément crochet côté verrouillage vient en prise avec l'élément crochet fixe. En outre, l'élément de liaison est placé dans un état où l'extrémité de l'élément de liaison, qui est située sur le côté relié à la section de mise en prise côté cabine, est tournée davantage vers le haut dans la direction verticale que l'extrémité de l'élément de liaison, qui est reliée à la plaque de support.
