Description

  The present invention relates to an elevator sill device provided at a lower part of an entrance between a car and a landing.

  Generally, a clearance of about 30 mm is secured between the elevator car sill and the landing sill because it is necessary to secure a clearance through which the door engaging device passes when the car travels. However, the sill gap is unnecessary when the car is stopped on the floor, and the sill gap may be required to be reduced when all the doors are open. In response to such a requirement, in the conventional sill gap closing device, the closing plate stored under the car floor projects toward the landing side when all the doors are open, and the sill gap is closed (see, for example, Patent Document 1). .
