Claims3
In a double deck elevator operable in an upward direction, said upward direction defining a corresponding leading deck and a trailing deck of said elevator, said elevator further being operable in response to upward direction hall calls at a plurality of floors input by waiting passengers and car destination calls input by riding passengers on one or both decks, a method for operating said elevator to service intermediate floors during periods when the trailing deck is empty, comprising the step of:
- answering all upward direction hall calls for said elevator by the leading deck, except upon occurrence of at least one of the following conditions:
- a) wherein a first, next upward direction hall call at a first floor occurs concurrently with a second unanswered hall call at the next upwardly sequential floor, or
- b) wherein a next upward direction hall call at a first floor occurs concurrently with a car destination call for the next upwardly sequential floor.
In a double deck elevator operable in an upward direction and a downward direction, each operating direction defining a corresponding leading deck and a trailing deck of said elevator, said elevator further being operable in response to upward and downward direction hall calls at a plurality of floors input by waiting passengers and car destination calls input by riding passengers on one or both decks, a method for operating said elevator comprising the steps of:
- determining the absence of passengers on the trailing deck of said elevator, and in response to said absence of said passengers performing the step of:
- answering all hall calls for said elevator's current operating direction by the leading deck, except upon the occurrence of at least one of the following conditions:
- a) wherein a first hall call at a first floor occurs concurrently with a second hall call at the next sequential floor, or
- b) wherein a next hall call at a first floor occurs concurrently with a car destination call for the next sequential floor.
