Abstract:
An elevator system provides service between a ground level and each of three upper levels through a single elevator shuttle hoistway system. Three elevator cabs (B,D,F) are moved in a triple deck elevator car frame, or a four deck elevator car frame (75) in a low hoistway (51); two cabs (A,C) are moved in a double deck elevator car frame or four deck car frame (76) in a mid hoistway (52); and one cab (P) is moved in a single deck car frame or triple deck car frame (77) in a high hoistway (53). Other embodiments have other car frame arrangements.
Abstract:
A particular elevator is commandeered to transfer an emergency cab F to (or near) a floor where an alarm has been sounded. The commandeered car is brought to the floor FF where the emergency cab is parked. The fire cab is exchanged for the normal cab C on the commandeered car, and is then carried to (or near) the alarm floor for responding to the alarm. Passengers in the normal cab may exit through landing doorways (23). Emergency personnel have access to the alarm area through emergency hoistway doors (27). A rack and pinion horizontal motive means for moving the cabs is illustrated.
Abstract:
Elevator cabs A-C move upwardly through three or more contiguous overlapping hoistways 38-40 in the upper decks of double deck car frames 41-43, and move downwardly through the hoistways in the lower decks (or vice versa). To switch between decks, the cabs are offloaded from the hoistways into auxiliary elevators 50, 51 at the terminal ends of the shuttle, and are moved to be adjacent to the other deck by the auxiliary elevator and loaded thereon for the trip in the opposite direction. A second embodiment has additional auxiliary elevators 64, 65 and additional cabs D, E so that loading and unloading of passengers do not delay movement of the cabs in the hoistways.

Abstract:
Double deck elevator cars (10-12) are moveable in corresponding adjacent overlapping hoistways (7-9). Passengers who have entered the bottom deck (39) of a first elevator (12) from a ground landing (41) are transferred into the bottom deck (47) of a second elevator (11) as passengers in the upper deck (46) of the second elevator are transferred to the upper deck (38) of the first elevator. Passengers in the lower deck (31) of a third elevator (10) are transferred to a lower landing (33) as passengers in an upper landing (32) enter an upper deck (30) of the third elevator. Passengers are thereafter transferred in the same fashion between the second elevator and the third elevator at a second transfer level (49).
Abstract:
In an elevator system having a low rise group of floors and a high rise group of floors and a swing car 16 having doors and car call buttons that enable it to operate in both the low rise group of floors and the high rise group of floors, interrise hall calls made within one of said group of floors for service within another of said group of floors are assigned to the swing car for response. In one embodiment, the call is assigned to the first car approaching the call in the right direction; in another embodiment, the call is assigned in accordance with ordinary hall call assignment logic.
Abstract:
An elevator cab X is moved from alanding TL to a car frame (11) simultaneously with moving a cab Y from the car frame (11) onto a landing TR. Double deck car frames (11a) may be utilized with cars P, Q going in the opposite direction of cars X, Y as they are transferred between the car frame and corresponding landings.
