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:
A rope climbing elevator (10) includes prime movers (40,42) and drive sheaves (32,34) secured to the car (10) and engaging stationary ropes (12-26).
Abstract:
The hoistways of passenger shuttle elevators are provided with freight landings (78) adjacent commercial businesses in the higher floors of a tall building; passenger cabs (71) are exchanged for freight containers (73) on the car frames (48) of the shuttle elevators, and the shuttle elevators are utilized to move the containers of freight from a freight receiving area (68) at the lower end of the building to the respective freight landings (78). In one embodiment, a ballast weight (80) is loaded onto a car frame as a container of freight is offloaded from the car frame so that the car frame may return to the freight receiving area for another container of freight, without the elevator being misbalanced. Another embodiment utilizes one of two decks for carrying containers of freight while the other deck carries an empty passenger cab, thereby to reduce the difference between the heaviest and lightest that the car frame will be as it returns empty to the freight receiving area for a subsequent container of freight. Another embodiment uses compound or other extensive roping and an extra large traction machine to permit returning a totally empty car frame to pick up a subsequent freight container.
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.
