Description: |
| This invention consists of a series of "small objects" such as chains, ropes or cloth from the leading edges and surfaces of an elevator car to provide a warning touch to anyone in the way of the car while it is moving. The invention relies on the person being able to quickly move out of the way when they feel the touch ("tickle") of the small objects. |
