  • Patent number: 5861586
    Abstract: Elevator cabs are transferred between elevators, which may be shuttles, in various levels of a building, such as transport floors, in response to car calls registered in the cabs and hall calls registered on the transport floors. The cabs may be transferred from carriages or bogeys onto elevator car frames in a lateral direction, which is perpendicular to the motion of the cab on a carriage or bogey, or in a longitudinal direction which is the same as the direction of motion of a cab on a carriage or bogey. The horizontal/vertical control and transfer may be effected in response to the arrival at transport floors of elevators having cabs therein, or in response to the arrival at an elevator of a bogey carrying a cab which must be transported between a transport floor on one level of a building and a transport floor on another level of a building, in order to serve the need of a car call registered therein or a hall call.

  • Patent number: 5785153
    Abstract: The arrival of each of four dual-hoistway shuttle elevators S1-S4 is synchronized with a selected one of ten local elevators L1-L10, or ten low rise elevators L1-L10 and ten high rise elevators H1-H10 at a transfer floor 26 by limiting 140 the speed of the shuttle, gradually 149, or rapidly 154, 155 decreasing the speed of the shuttle, delaying a local elevator by holding its doors open for extra time, or controlling the speed of a local elevator, by cancelling or avoiding hall calls. Empty local elevators may be allowed to remain at the high end of the building, or compelled to travel to the lobby if needed. Elevators approaching a transfer floor may be synchronized by adjusting the speed of one of them until the remaining distance is the same for both. Hall calls may be prevented, cancelled, or negatively biased in dependence upon the tardiness of a local elevator.

  • Patent number: 5752585
    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.

  • Patent number: 5732795
    Abstract: Normal power for the fan (22), lights (23), operating car panel (26), and cab controller functions (29) is provided from a voltage regulator (41) driven by a flywheel motor generator (38) which is accelerated when the elevator car (11) is near a landing by power supplied through brushes (34) from power tracks (32) disposed on the building (33). Power for the cab door operator (21) is supplied only directly from the brushes (34). A transceiver (46) provides all operational, safety and emergency phone voice communication with the building, whereby the traveling cable normally used on an elevator car is eliminated. The brushes are extended to engage the power tracks by means of springs (176), and are retracted into a clearance position by means of solenoids (174).

  • Patent number: 5712456
    Abstract: An elevator system, having a three phase rectifier (20) which converts energy from a three phase AC main (21) to provide DC power on a bus (19) to a three phase inverter (18) that drives a three phase inductive hoist motor (17), utilizes regenerated energy applied (46, 47) to a boost regulator (52) to drive (54, 55) a flywheel motor generator (26) to store the regenerated energy in the form of inertia therein. When the flywheel motor generator reaches a limiting speed, any continued regenerated energy is dumped (59, 60) in an energy dissipating device (61). During periods of high demand, the inertial energy stored in the flywheel motor generator is utilized (67, 68) to add energy to the DC bus to provide additional current to the three phase inverter for driving the hoist motor. The control is provided by software embedded in an elevator computer (such as used for dispatching and motion control).
