Description

  The present invention relates to an elevator entrance / exit rainwater intrusion prevention device suitable for use in an elevator in which an elevator car is installed outdoors.

  In the elevator for observation, since the elevator car is installed outdoors, rainwater falls directly on the elevator car. Therefore, in the conventional elevator, rain gutters are provided at the upper part of the landing side entrance and the upper part of the car side entrance, respectively.

  In addition, as a conventional elevator for observation, an elevator is provided with a bowl-shaped member that receives rainwater dripping from above along the car glass of an elevator car installed outdoors or a car glass upper exterior plate material, and causes the rainwater to flow out of the glass surface. An elevator provided at the lower part of a car room is known (for example, see Patent Document 1).
