METHOD AND EQUIPMENT FOR INVITEING CALLS

The invention relates to a method and apparatus for displaying valid basket calls to passengers traveling from the floor to the elevator 5, where in the elevator the basket calls are provided by basket mounted basket call buttons and the basket calls are taken to the elevator control.

In the elevator car, passengers define their target layer by pressing the 10-mile basket call buttons on the elevator car. The buttons are mounted on the wall of the elevator car or on a separate control panel which also contains other control and display devices. Usually, the selection of the target layer is indicated by an indicator next to the button, on top of which the passenger pressing the button 15 and other passengers in the basket and later on may indicate that the call is being served. The basket call buttons are usually located in the immediate vicinity of the basket door, either on the door wall, which is the only practice in many countries, or on the wall adjacent to the door.

20 The arrangement works when the elevator cars are small and the number of passengers is small. Passengers do not have difficulty detecting the call button.

'···' When the elevator cars are large and the number of passengers' 25 becomes significant, especially in congested situations, it is difficult for a new passenger entering the elevator in all situations: to detect the status of the push button on his target floor, i.e.

•:: whether it has already been printed by a person who has already entered the elevator or has a .'j *. not yet selected. With the basket call buttons placed on the 30 door walls, the passenger still has to turn to see the y · 'buttons. Because call buttons are usually located about 0.9 - * ..! At a height of 1.2 meters, a new passenger will have to peek at • or among other passengers or penetrate past them near the call buttons in order to: 35 be able to ascertain the status of his target layer.

• · · •> • · i • · ·

Not only do passengers feel uncomfortable * · the situation results in a significant reduction in the transport capacity of the elevator under certain operating conditions.

2 111935

The elevator car door is blocked as passengers stop and turn to check the status of the push button on their target floor. As a result, the opening hours of the elevator in question will increase. In addition, it may still be the case that, as a reflective effect, the actual travel time or standstill time of the elevator car belonging to the same elevator group differs from what is assumed in each traffic situation when designing group control programs. Further, the elevator start delay may be delayed because the elevator door control interprets 10 movements as meaning that someone still wants to exit the elevator car at that level. Passengers in the basket, on the other hand, find the situation intrusive when their "intimacy" is disturbed. All in all, the uncertainty about the future behavior of the elevator, previously picked up by passengers using the basket buttons 15, causes delays, especially for those using the elevator daily, and causes aggressive feelings on an otherwise pleasant and relaxing elevator journey.

20

The object of the present invention is to eliminate, or at least significantly reduce, the disadvantages described above for elevator passengers and elevator use, and thus to improve the transport capacity of the elevator, as well as its comfort and comfort.

To achieve this, the method according to the invention is characterized in that at least when the elevator car reaches the floor level: providing a display device which at least indicates information on which floors the car call exists. Correspondingly, the apparatus according to the invention is characterized in that a display device is provided in the elevator car with which to operate. invitations are visible at least when the elevator car is stopped for a passenger entering the elevator on the floor level.

The solution according to the invention significantly improves: 35 the comfort of the elevator passenger when he / she can easily. detect whether the call button on his target layer has already been pressed.

! Particularly in office buildings with a large number of daily elevator users, passengers will greatly benefit not only from a quiet elevator journey but also from a fast service as the 3 111935 elevator capacity increases in practice due to reduced waiting times. The elevator also works better with the rules and controls designed for the elevator.

5 The additional layer indicating target layer is simple and easy to implement at no cost. The solution according to the invention is illustrative and easy to understand.

The auxiliary display can also be retrofitted to various existing elevators having control systems 10 different from those currently in use.

The invention will now be described in more detail with reference to an embodiment, with reference to the drawings, in which Fig. 15 shows a display according to the invention, Fig. 2 shows a connection of the display to the elevator control apparatus.

When the elevator car 2 is stopped on the floor level 4, the car doors and the level doors 6 are guided to the open position as shown in Figure 1. external calls in any direction, up or down. A display panel 25 12 is provided above the elevator level door indicating the direction of travel of the elevator in question. Direction of travel: the display and the corresponding loudspeaker connected to the device are usually displayed shortly before the lift reaches floor level 4, allowing passengers to advance; to the right elevator car.

30th On the side wall of the elevator car 2 or, as shown in dashed lines in Figure 1, on the door wall there are mounted call buttons 14 for elevator calls, whereby the elevator passengers can select:; : after entering its target floor in the elevator car 2. Call buttons 14 are implemented, for example, with push buttons having an indicator light, *, which indicates activation of the basket call in question. Call buttons •; other * * «*» signaling devices are often provided in the vicinity or in the vicinity to inform passengers of the direction of movement of the elevator, the location or the upcoming stops.

At the top of the elevator door opening is mounted a basket call display 16 according to the invention, showing the target layers of the activated basket calls of the elevator car, i.e. the layers on which 5 basket call buttons are printed. The numeric display activates the selected target layer identification 18 by illuminating the lamp at that identification. The selected target layer may also be displayed, for example, by activating the perimeter around the number or by other known techniques.

In the case of Fig. 1, target layers 5,6 and 12 are active. Preferably, standard display information 16, and in particular an audio outboard or loudspeaker directed outwardly from the car, are attracted to the display 16 to draw attention of

As the elevator car 2 reaches level 4 and the elevator doors 6 open, the passenger detects valid basket calls 18 on the basket call screen 16 and, if the call is already on, can enter directly into the basket 20 without having to access the basket call buttons 14.

In the event of a congestion, the first press of the body button on the target layer in question is transmitted to the rest of the screen so that they do not have to rush to the push buttons. Thus ':' the elevator car will be loaded faster and the stop time at: j (: 25 will decrease accordingly.

; The basket call display 16 is preferably implemented by pressing. screen with screen printing building floors and; , when the basket call is active, the respective floor number 30 is illuminated by an LED mounted above the floor number. The display is., Positioned above the door as in Figure 1, where it is displayed on the floor level. The display may also be located at the top of the rear wall of the basket s * '·; · * such that it is clearly visible from the plane.

::: This will also allow passengers already in the basket to see the activated 35 basket calls throughout the journey. Another advantageous solution is to · · », arrange the display duplex and set the display doorway; at the top or slightly above the door and at the same time slightly off the wall so that the display is clearly visible from the plane when the doors are open and passengers in the basket see the display 5111935 in the natural direction, i.e. looking towards the door.

Figure 2 illustrates the connection of the display 16 according to the invention to the basket calling apparatus. The basket call buttons 14 are coupled 5 to the elevator control device 20 via the elevator access device 24 and the communication link 22, which upon receipt of the call sends the acknowledgment information to the call buttons 14. The communication technology used and other peripheral equipment can be implemented in a number of An indicator light 19 of the basket call display 16 is connected in parallel with the signaling light circuit of the call button 10 via the conductors 28 and the ballast 26. The ballast may simply be a terminal block on a display board and the wires are implemented with a flat cable. The 15 basket calls given by the basket call button will cause the indicator light on the corresponding call button to light up when the elevator control has accepted the call and thus promised to serve it. Simultaneously, the corresponding light of the basket call screen 16, which in the example of the figure is implemented by LEDs 19, indicates the selected target layer.
