Description

  The present invention relates to an elevator that includes a landing and an elevator car that stops opposite the landing, and that is provided with a movable platform that fills a gap between the elevator car and the landing.

  In a conventional elevator, as shown in Patent Document 1, a fixed platform is fixed to a car sill provided in a car in order to compensate (fill) a gap between the car and a landing. In this case, in order to avoid interference between the fixed platform and the landing when the elevator car moves up and down in the hoistway, it is necessary to secure a certain amount of clearance between the fixed platform and the landing. Therefore, when the user moves between the car and the landing, there is a problem that an object is dropped in the gap or shoes or high heels are put in the gap.

  In recent years, as shown in Patent Document 2, an elevator including a car-side movable platform that is provided so as to freely advance and retreat from a car sill toward a landing side is used. In this case, when the elevator car is stopped at the landing, the car-side movable platform protrudes toward the landing sill side to fill a gap between the car sill and the landing sill. On the other hand, when the elevator car moves up and down in the hoistway, the car-side movable platform is prevented from retreating to the car sill side and interfering with the landing sill. According to such a car-side movable step, the gap between the car and the landing can be filled more narrowly than the elevator described in Patent Document 1.
