Abstract: There is provided a display system for an elevator which can display an operating state of an elevator car without a sense of discomfort even though data transmission performance is not improved. Data concerning an operating state of an elevator car is transmitted from an elevator control device to an information display device set in the elevator car or the like through a transmission cable. At this time, the information display device side infers the next data which should be displayed in synchronization with an operation of the elevator car. As a result, even if data transfer from the elevator control device is delayed at the time of a high-speed operation, the inferred data can be used to display an operating state of the elevator car without a sense of discomfort.

Abstract: A position indicator display system for an elevator. The elevator position indicator has a segmented display capable of producing alpha-numeric characters. The segmented display operates in a predetermined power range that may or may not match the operational voltage used by the rest of the elevator's systems. Within the elevator position indicator, a display driver is coupled to the segmented display. The display driver receives a location signal from the systems controller of the elevator. The display driver arranges the location signal to drive the segmented display and produce an alpha-numeric character indicative of the location signal. Since the elevator's operational voltage may differ from that of the elevator position indicator, a power conditioning circuit is provided. The power conditioning circuit selectively alters the power of the location signal so that the location signal falls within the operational power range of the segmented display.

Abstract: An elevator drive has a traction sheave over which ropes are passed to move an elevator car and a counterweight up and down in an elevator hoistway. An elevator control in a control cabinet on a landing is connected with another elevator control in the hoistway and with the elevator car, and controls how the elevator car moves. The control cabinet also has a handle that is part of a Bowden cable acting on a brake of the elevator drive. The handle can be used to manually release the brake which permits the elevator car to move up or down depending on the difference in weight between the elevator car and the counterweight. The position of the elevator car in the hoistway is of significance to the elevator control. A tensioned toothed belt spanning the height of the hoistway is in contact with an encoder that detects the absolute position of the elevator car for the elevator control. For evacuation, a signal device is provided which allows evacuation of the car without looking into the elevator hoistway.
