| | Patent 4723627: Double decked elevator car |
 | | A double decked elevator car as claimed in claim 2 wherein the common back wall of the upper and lower cars is formed with an outwardly projecting portion spaced apart from the floor of said upper car and the ceiling of said lower car so as to constitute said communicating means. |
 | | A double decked elevator car as claimed in claim 2 wherein said opening of the upper car is disposed in the floor thereof and said opening of the lower car is disposed in the ceiling thereof, each said opening being immediately adjacent to said common back wall. |
 | | Therefore, in a conventional double decked elevator, an indicator is disposed within each car for communicating the calls to the passengers in the upper and lower cars, which however is insufficient to remove an anxiety arisen due to the passengers feeling isolated. |
