Abstract:
An elevator shuttle includes a plurality of elevator hoistways (14, 19, 24) which overlap, the elevator car frames (13, 21, 25) traveling in each hoistway including two decks per cab being carried by the car frame, plus an extra deck on car frames (20) in other than the highest (24) and lowest (14) hoistways. This allows cabs (C) traveling simultaneously, upwardly, in three or more hoistways to pass cabs (A, B) simultaneously traveling downwardly in those hoistways. The cabs may be loaded and unloaded while in the hoistway (Figs. 1, 13, 21) , or while in off-hoistway landing areas (Fig. 28). Embodiments include one cab per hoistway and two cabs per hoistway; three hoistways and four hoistways.
Abstract:
To prevent elevator rope stretch effects when a horizontally transferable elevator cab (18) is rolled onto and off of an elevator car frame (10), an elevator car/floor lock (31) includes a bolt which extends across the interface between the car frame and the building and engages a strike. Jack screw and solenoid embodiments are shown. The bolt may extend from the car frame to the building (Figs. 1-4) or from the building to the car frame (Fig. 5).
Abstract:
An elevator system has a low rise group of floors and a high rise group of floors and a swing car 16 having doors and car call buttons enabling it to operate in either the low rise or high rise, the swing car 16 being assignable to one of the other rise depending upon the burden, but also being able to accept calls in the other rise in response to a variety of characteristics of traffic within the elevator system. In one embodiment, the swing car 16 is always assigned at the lobby to the low rise but proceeds into the high rise in response to hall calls therein; the swing car 16 can accept down calls in the low rise if there is a high burden in the low rise or a down call has been waiting for a long time, or if the car has a very light load. Dedicated cars 15,17 may be shut down and only the swing cars 16 used at nights and on weekends. At nights and on weekends, the high rise and low rise can be effectively merged into a single system served by swing cars, thereby to save energy in light traffic.

Abstract:
An elevator control system employs a microprocessor- based group controller 17 which communicates with the cars 3,4 of the elvator system to determine the condition of the cars, and responds to hall calls 18, 19, 20 registered at a plurality of landings in the building serviced by the cars under control of the group controller, on a cyclic basis which recurs several times per second, to assign every unanswered hall call to a car deemed best suited for response to that call, in each cycle, based upon the information provided by the car to the group controller within that cycle of operation, In any cycle in which a call is assigned to a car other than a car to which the call had previously been assigned, the assignment of the call to the previous car is nullified. At the end of each cycle, any car which indicates that its committable position coincides with the floor of a hall call which has been assigned to it will receive a stop command. In the assignment ofcallsto cars, preference is given to any car which previously had the call assigned to it, although the preference is relative and not absolute.
Abstract:
An elevator control system employs a microprocessor- based group controller 17 which communicates with the cars 3, 4 of the elevator system to determine conditions of the cars and responds to hall calls 18, 19, 20 registered at a plurality of landings in the building serviced by the cars under control of the group controller, to provide assignments of calls to cars based on the summation for each car, with respect to each call, of a plurality of weighted system response factors some of which are indicative of conditions of the car irrespective of the call to be assigned, and some indicative of conditions of the car relative to the call to be assigned. Such factors include preferring cars which are running, which require motion to provide service already assigned to the car, which do not have lobby calls, which are not positioned at the lobby, which are not full, even though the car may have a car call at the floor of the hall call under consideration, which do not have excessive car calls in them, and so forth.
