Definitions

  • Controls for multicompartment elevator cars including, one, an arrangement operating while a car is parked and in response to the answering of a hall call for one direction of travel by one compartment to delay for at least a predetermined period the answering of a hall call for the other direction by the other compartment; two, an arrangement for preventing under certain circumstances the registration of certain car calls in each of the compartments of a car; three.
  • FIG. 9 FREDERICK HENRY NOWAK HENRY JOSEPH PASTERNAK sYz ig ATTORNEY PATENTED DEC 7 I97I SHEET OSUF 17 FREDERICK HENRY NO WAK HENRY JOSEPH PASTERNAK BY Z'f ATTORNEY so I HGE FIG. IO
  • This invention relates to elevator control systems for cars having multiple passenger compartments. More particularly, it pertains to improvements in-elevator control systems for cars having two compartments.
  • a double compartment elevator car can serve two landings simultaneously.
  • a single compartment car would in the same installation because it can answer the same number of calls in less time with less stops.
  • One known arrangement for multicompartment cars operates a group of such cars under the control of a well known groups supervisory system in which the cars travel in what is known as round trips. Each car starts each trip from the bottom tenninal, travels up either to the top terminal or to a landing below that terminal for which a call is registered, usually the highest call, and then returns to the bottom terminal. During light traffic periods all cars park at the bottom terminal waiting to be dispatched as needed.
  • the answering of an up or a down hall call registered at the landing at which a single compartment car is located is accompanied by the opening of the car's doors in response thereto.
  • This is accomplished by providing either an arrangement in which the hall call establishes the appropriate direction of travel for the car before the doors are opened or an arrangement in which the car call registered by the passenger upon entering the car establishes the appropriate direction of travel.
  • neither arrangement is there anything more than a remote chance of a passenger unknowingly boarding the car and being taken in a direction opposite to that in which he desires to travel; even in those situations in which he is one of two passengers who both register calls at the same landing for opposite directions of travel.
  • that which establishes direction before the doors are opened one of these two calls is not cancelled and the system indicates which passenger has preference in using the car.
  • both calls might be cancelled but the passengers themselves can decide who should have preference.
  • a double compartment passenger elevator car is employed in a suitable installation having a control system in which the car can remain at rest at a position intermediate the terminal landings, it means that the car can park with its upper compartment located adjacent one landing and with its lower compartment located adjacent the next lower landing.
  • the system it is desirable to have the system arranged so that the answering of a hall call for one direction of travel registered at the landing adjacent one compartment delays the answering of a hall call for the other direction of travel registered at the landing adjacent the other compartment for at least a predetermined period of time. Otherwise, one compartment could answer a hall call registered by an intending passenger desiring to travel in one direction while the other compartment was answering a hall call registered by another intending passenger desiring to travel in the opposite direction.
  • a hall call herein is meant those operations which a car undergoes in order to provide service to the intending passenger who registered the call.
  • these include (i), causing the car to travel to the landing at which the call is registered and to stop with one of its compartments located adjacent thereto, if one of its compartments is' not already so located, (2), opening the doors of that compartment, (3), cancelling the call, and (4), lighting a hall lantern indicating the availability of the car to travel in the direction indicated by the call.
  • control systems can be arranged so that some of the forgoing operations take place notwithstanding a call is not being answered.
  • a hall call is registered at the landing adjacent the other compartment for the direction opposite that of the hall call being answered, according to the invention, the answering of the opposite direction hall call is delayed for at least a predetermined period of time.
  • the unanswered hall call is not cancelled and does not cause the lighting of a hall lantern indicating the availability of the car for travel in its direction. Should this time elapse without the registration of a further call for the same direction of travel as the answered call, the opposite direction hall call is then answered as a result of which it is cancelled and the proper hall lantern is lighted.
  • the disclosed embodiment is arranged so that a car answers a hall call only after it has a direction of travel established which corresponds to that indicated by the call which is being answered. This insures the availability of the car for travel in the direction indicated by the call before the call is answered. Thus, some of the operations included in answering a hall call such as cancelling the call and lighting the proper hall lantern cannot occur before the direction corresponding to the call is established. Accordingly, the passenger is provided with an indication that his call is being answered only after the car is prepared to travel in the direction indicated by his call.
  • multicompartment elevator cars Another advantage of multicompartment elevator cars is that the service they provide from particular landings can be restricted.
  • service from the first two landings can be restricted such that passengers boarding the lower compartment at the first, or lower lobby, landing can only register car calls for landings arbitrarily identified as odd landings while those boarding the upper compartment at the second or upper lobby, landing can only register car calls for the remaining landings identified as even landings.
  • a car can stop in answer to a hall call with either compartment located adjacent an intermediate landing. If restricted service is provided in this system, provision must be made to remove the restriction to permit an intending passenger at such an intermediate landing to register a car call for any landing in either compartment.
  • Restricted service may also extended to an intermediate landing above the first two landings, not withstanding passengers enter one of the compartments at this landing.
  • separate odd and even landing hall call registration devices are provided at this landing.
  • intending passengers by registering whether they desire to travel to an odd or even landing cause a lower, or odd landing serving compartment, or an upper, or even landing serving compartment, respectively, to stop in answer to the call adjacent the landing at which the call is registered.
  • Signs may be employed at this landing to instruct intending passengers which landings a compartment is serving so that when the doors open they may be informed as to whether the compartment will transport them to their desired destination or not.
  • the disclosed system attempts to keep two cars parked with their compartments adjacent the upper and lower lobbies for serving intending passengers thereat. Moreover the system is arranged to attempt to keep at these lobbies one car whose lower compartment serves a particular intermediate landing to which restricted service is extended and one car whose upper compartment serves this particular landing.
  • the third landing is the intermediate landing to which restricted service is extended and by parking cars at the lobbies in the foregoing manner, a car which can serve the third landing is provided at both lobbies for passengers who desire to travel from either lobby to the third landing.
  • One of the cars at the lobbies is selected as the next to leave.
  • provision is made for transferring selection in case the selected car is not capable of serving the third landing with that one of its compartments which is adjacent the lobby level at which a passenger desiring to travel to the third landing is located.
  • the registration of a hall call at either of the lobbies without the subsequent registration of a car call in one of the compartments of the selected car within a predetermined period causes a selection transfer operation to select the other car parked at the lobbies.
