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:
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:
A plurality of elevator shuttles (1-10) are dispatched in a sequence at regular intervals which extend across the average round trip run time for all of the shuttles, by enabling a shuttle to run (101, in response to the shuttle being ready to run (96) following expiration of a dispatching interval (97) which equals the average run time of all the shuttles (91).
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.
Abstract:
Horizontally movable elevator cabs (22, 23) are transferred from the upper deck of a first car frame (26) to the upper deck of a second car frame (27) and from the lower deck of the second car frame to the lower deck of the first car frame. Three elevator hoistways, each with a double deck car frame are controlled by computer routines. A rack and pinion horizontal motive means, for moving the cab from car frame to car frame is also briefly disclosed.
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).
