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 first slidable auxiliary pinion (58a) on the bottom of a horizontally moveable elevator cab A disposed on a car frame (14) or a landing is moved out from under the cab toward another car frame (13) or landing by means of a motorized pinion (56) until it engages a motorized pinion (57) on the adjacent car frame (13) or landing, which then pulls the auxiliary pinion and the entire cab toward the other car frame or landing until a main rack (45) fixed to the bottom of the cab engages a motorized pinion (34) on the other car frame (13) or landing, which pinion then pulls the entire cab onto the other car frame or landing. The auxiliary racks (58a, 58b) may be mounted on a common auxiliary rack member (58), or may be separate. The auxiliary motorized pinions (55, 56, 57) may be bidirectional, or may be unidirectional and mounted on the same shaft with main pinions (32a, 32c; 33a, 33c; 34a, 34c).
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:
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 cab lock (25) includes a lug (32) on a horizontally moveable elevator cab (17) that receives a bolt (35) which is urged into the lug by a spring (45) and retracted from the lug by means of a solenoid (43) disposed on the elevator car frame. Switches (41, 42) keep track of the position of the bolt; locks may be used on car frames, landings and carriers in various configurations.
Abstract:
To prevent elevator rope stretch effects when a horizontally transferable elevator cab is rolled onto and off of an elevator car frame, an elevator car/floor lock 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. To take the weight off the lock bolts so that they may be retracted to permit moving the car frame vertically in the hoistway, strain gages or load sensors provided in or adjacent the bolts sense the weight supported thereby, and a pretorque program provides armature current to the hoisting motor to raise or lower the car frame sufficiently to reduce the load on the bolts to nil.
Abstract:
Horizontally moveable elevator cabs A-E are transferrable between the car frames (72) of two elevators HI, LO in adjacent hoistways which extend between at least three levels (GND, MID, SKY) of a building, and between the car frames and landings L, R at said levels. The vertical movement of cars in the hoistways is synchronized, and transfer of elevator cabs between landings and car frames is simultaneous.
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:
A safety gate (24) is slidable vertically from an upper position at an elevator cab landing (22) where it obstructs movement of the elevator cab (20) into a hoistway, and a lower position that permits cab travel between a car frame (29) and the landing. An actuator (42) normally urges the gate upwardly; the actuator is moved by a cam assembly (35) on an approaching elevator car frame so as to slide the gate (24) downward, out of the way of cab motion.
