Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an elevator in which one car has two or more entrances and exits, and relates to a car circle display device that displays which door will open in four rooms. .

[Background of the invention]

In elevators where one car has two or more entrances and exits, opening the doors at the same time must be avoided for the safety of the passengers. For this reason, on a floor with an entrance/exit on only one side, the car door opposite the landing entrance/exit opens, and on a floor with two entrances/exits, depending on the passenger's request (car call, hall call registration status), either It is common to force one side to open one at a time. On the other hand, it is difficult for passengers in the car to predict which side door will open when the elevator stops at the landing floor.

In such cases, conventional methods were only recognized by the movement of the door opening, which lacked safety. Particularly in the case of a wheelchair user, etc., there was a drawback that safety was lacking and preparations for getting on and off the vehicle could not be made in advance.

[Purpose of the invention]

The purpose of non-invention is to have two or more out of one car.

To improve safety and provide an elevator that is easy to ride by guiding passengers in the car to which door is h<71> et+ when the elevator stops at a visitor floor in a crowded elevator.

[Summary of the invention]

The key point of the present invention is to provide a door opening guidance indicator light above each doorway of the next car, and to illuminate the door opening side before the door opens to guide passengers.
Alternatively, a speaker may be installed near each entrance and exit, and before the door opens, a speaker on the door opening side may be used to announce to passengers that the door is opening.

[Embodiments of the invention]

Figure 81!1 is a sectional view of the elevator hoistway. The front side stops on the 1st and 3rd floors, with landing doors 11i'D and 3FD7 respectively.
5, and the rear (1ftl stops on the 2nd and 4th floors, with landing doors 2FB and 4FR respectively, in the hoistway, the front side car p
A car C with two entrances, cpD and rear car door CRD, is suspended by a rope R, indicating an elevator that is in service from the first to fourth floors.

Figure 2 (a) is a plan view of the elevator hoistway, showing the case where the elevator is stopped on the first floor. are provided, and furthermore, a front side speaker 81'B' and a rear speaker 81'B' are provided.
A downward facing S I) R is provided near the door.

FIG. 2(b) is an elevational view of the front side car door.

A display device IP including a door opening guide device is installed above the front car door CFD, and a speaker 8 PF is installed above the elevator operation panel OFF.

As expected, each device is installed on the back side as well as the front side.

Figure 2(C) is a detailed diagram of the display device Ii), the car position indicator lights CP, IL and the door opening guide indicator lights DLA, J)L.
B is provided.

Door opening guide indicator light 1) LA lights up when the front side is opened if it is on the front side, and when the back side 1111 is opened if it is on the back side. Further, the door opening guide indicator light DLB lights up under the opposite condition.

FIG. 3 is a circuit diagram of the present invention. L1 and L2 are power supply busbars, and SD is a contact of the 1 speed relay, which closes at 1 when the vehicle starts decelerating and the door is opened to stop at an arbitrary floor. IS to 4S are fixed contact pieces of the car position detection device, and IS is provided on the first floor and 4S is provided on the 41st floor, and they are arranged so that the center of the vertical length is at the level of the corresponding floor. Fll-j: A movable contact that moves in synchronization with the car and is installed at the floor level 1k of the corner of the car.

Now, to explain the case where the elevator operates from the 1st floor to the 3rd floor, when the elevator reaches the 3rd floor, the movable contact F faces the fixed contact piece 3S, and the contact SD of the deceleration relay closes, the circuit of Structure #: To be done. In other words, the speaker on the front side J11 broadcasts that the front I country F opens (broadcast content is "The door on this side opens @ first", etc.), and the front (4th 1st) is the DLA
The DLB lights up on the back side B, and the front side F opens to guide the cow. In this way, the structure is the same no matter which floor it stops at.

This is naive, even if there are entrances and exits on both the front and back of the landing, there will be a guide linked to the door opening condition, and this will not be a problem in implementing the present invention. For the voice guidance of the speaker, you can use a pre-recorded red tape or a voice synthesis LSi. Furthermore, the content of the guide text is not suitable if it expresses which door is to be opened.

It is also possible to intuitively guide a misfire ψJ by painting the car door in a different color from the front and back when viewed from inside the car.

〔Effect of the invention〕

According to the present invention, safety is improved by guiding passengers in the car as to which side of the door will be opened before opening the door, and alerting them to the door.

[Brief Description of the Drawings] Fig. 1 is a sectional view of the elevator hoistway, Fig. 2 is a plan view of the elevator hoistway of the present invention (a), a front view (bl and an explanatory view of the door opening guide device i (c), FIG. 3 is a circuit diagram of the door opening guide device of the present invention.
