Abstract

Provided is an elevator device, including: a cage; a car entrance frame including: entrance columns provided at a car entrance of the cage; and an entrance top plate provided on a top side of the car entrance; a car door configured to open and close the car entrance; a projector, which is provided to the car entrance frame so as to be capable of projecting information onto an image display surface provided at a landing when the car door is opened upon arrival of a car at the landing; and a control device configured to control respective operations of the car door and the projector. When the control device controls the car door to open, the control device controls the projector to project the information onto the image display surface.

First claim

The invention claimed is:

1. An elevator device, comprising:
a cage;
a car entrance frame including:
entrance columns provided at a car entrance of the cage; and
an entrance top plate provided on a top side of the car entrance;

a car door configured to open and close the car entrance;
a projector, which is provided to the car entrance frame so as to be capable of projecting information onto an image display surface provided at a landing when the car door is opened upon arrival of a car at the landing; and
a control device configured to control respective operations of the car door and the projector,
wherein, when the control device controls the car door to open, the control device controls the projector to project the information onto the image display surface.

2. The elevator device according to claim 1 ,
wherein the image display surface is provided on a floor of the landing, and
wherein the projector is provided to the entrance top plate of the car entrance frame so as to be capable of projecting the information onto the image display surface.

3. The elevator device according to claim 1 , further comprising a jamb including:
vertical frames provided at a landing entrance of the landing; and
a head frame provided at a top side of the landing entrance,

wherein the image display surface is provided on the vertical frame of the jamb of the landing, and
wherein the projector is provided to the entrance column of the car entrance frame so as to be capable of projecting the information onto the image display surface.

4. The elevator device according to claim 3 , wherein light projected from the projector enters perpendicularly on the image display surface.

5. The elevator device according to claim 1 , wherein, when the control device controls the car door to close, the control device controls the projector to stop projection of the information onto the image display surface.

6. The elevator device according to claim 2 , wherein, when the control device controls the car door to close, the control device controls the projector to stop projection of the information onto the image display surface.

7. The elevator device according to claim 3 , wherein, when the control device controls the car door to close, the control device controls the projector to stop projection of the information onto the image display surface.

8. The elevator device according to claim 4 , wherein, when the control device controls the car door to close, the control device controls the projector to stop projection of the information onto the image display surface.
