Abstract
Abstract An elevator system including an elevator car mounted for movement in a building to serve the floors therein. The elevator system includes control apparatus for selecting the service direction in which the elevator car will proceed from a floor it is serving. A display having an array of electrically energizable elements visually indicates the selected up or down service direction by sequentially energizing the elements to provide a predetermined pattern which moves upwardly, or downwardly, through the array, or which causes a predetermined pattern to lengthen in the upward, or downward direction.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
100 words
An elevator system, comprising: a building having a plurality of floors, an elevator car mounted for movement in said building to serve the floors, control means for selecting the service direction in which said elevator car will proceed from a floor it is serving, and display means having an array of electrically energizable elements, said display means including pattern selection means responsive to said control means, said pattern selection means selectively energizing said elements while said elevator car is serving a floor to provide a predetermined sequence of at least three different patterns which visually indicate the selected service direction.
Claim 2
Dependent Claim
100 words
An elevator system, comprising: a building having a plurality of floors, an elevator car mounted for movement in said building to serve the floors, control means for selecting the service direction in which said elevator car will proceed from a floor it is serving, and display means having an array of electrically energizable elements, said display means including pattern selection means responsive to said control means, said pattern selection means selectively energizing said elements while said elevator car is serving a floor to provide a predetermined sequence of at least three different patterns which visually indicate the selected service direction.
Claim 3
Dependent Claim
27 words
The elevator system of claim 1 wherein at least certain of the energizable elements are included in patterns used for both the up and down service directions.
Claim 4
Dependent Claim
53 words
The elevator system of claim 1 wherein the elevator car and building include cooperative doors for controlling access to the elevator car, and wherein the display means is carried by the elevator car in a position visible outside the car from a floor at which the car is standing with the doors open.
Claim 5
Dependent Claim
40 words
The elevator system of claim 1 wherein the elevator car and building include cooperative doors for controlling access to the car, and wherein the display means is located outside of the elevator car adjacent to the door of the building.
Claim 6
Dependent Claim
32 words
The elevator system of claim 1 including audio signal means, said audio signal means providing an audio signal when the pattern selection means energizes the elements to indicate the selected service direction.
Claim 7
Dependent Claim
37 words
The elevator system of claim 5 wherein the audio signal includes a plurality of discrete audio signals with a predetermined characteristic of the discrete audio signals changing from signal to signal to indicate the selected service direction.
Claim 8
Dependent Claim
43 words
The elevator system of claim 6 wherein the predetermined characteristic is the frequency of the discrete audio signals, with the frequency increasing from signal to signal when the selected service direction is up, and decreasing from signal to signal when it is down.
Claim 9
Dependent Claim
45 words
The elevator system of claim 6 wherein the predetermined characteristic of the discrete audio signals is the sound level, with the sound level increasing from signal to signal when the selected service direction is up, and decreasing from signal to signal when it is down.
Claim 10
Dependent Claim
17 words
The elevator system of claim 5 wherein the audio signal is continuous through a sequence of patterns.
Claim 11
Dependent Claim
41 words
The elevator system of claim 9 wherein a predetermined characteristic of the audio signal continuously changes to audibly indicate the selected service direction, with the predetermined characteristic increasing when the selected service direction is up, and decreasing when it is down.
Claim 12
Dependent Claim
23 words
The elevator system of claim 1 wherein the predetermined sequence of different patterns repeats during the time the car is serving a floor.
Claim 13
Dependent Claim
21 words
The elevator system of claim 11 including audio signal means which is energized for only one sequence of the different patterns.
Claim 14
Dependent Claim
14 words
The elevator system of claim 1 wherein the one sequence is the first sequence.
Claim 15
Dependent Claim
22 words
The elevator system of claim 1 wherein the electrially energizable elements of the array are arranged in a single vertically oriented column.
Claim 16
Dependent Claim
44 words
The elevator system of claim 14 wherein the elements are sequentially energized and deenergized to provide an ascending visual signal in response to a selection of the up service direction, and a descending visual signal in response to selection of the down service direction.
Claim 17
Dependent Claim
65 words
The elevator system of claim 14 wherein the elements are sequentially energized and each element remains energized for a selected period of time, to provide a visual signal which increases in length in the ascending direction in response to a selection of the up service direction, and which increases in length in the descending direction in response to a selection of the down service direction.
Claim 18
Dependent Claim
78 words
The elevator system of claim 1 wherein the electrically energizable elements of the array are arranged in rows and columns, with the different patterns of a predetermined sequence responsive to the selection of the up service direction each including an inverted V-shaped configuration which moves upwardly through the array, and with the different patterns of a predetermined sequence responsive to the selection of the down service direction each including a V-shaped configuration which moves downwardly through the array.
Claim 19
Dependent Claim
30 words
The elevator system of claim 17 wherein the inverted V and normal V configurations each include a trailing portion which grows in length with each new pattern of a sequence.
Claim 20
Dependent Claim
77 words
The elevator system of claim 1 wherein the electrically energizable elements of the array are arranged in rows and columns, with the different patterns of a predetermined sequence each including a triangular configuration which increases in area with each step of the sequence, with one side of the triangular configuration being horizontal and with the opposite corner thereof being above said side when the selected service direction is up, and below said side when it is down.
