Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator hall entrance/exit device.

In particular, the present invention relates to an elevator landing entrance/exit device in which the landing door can be opened with an unlock key.

[Conventional technology]

Generally, the elevator landing door and car door are opened and closed by the first car door drive system after the passenger has stopped at the destination floor when a call is made using the call button or when a destination is instructed in the car. This allows the shutters to open and close at the same time. However, the landing door and the car door are opened and closed not only during the normal operation but also during maintenance operations and emergencies. That is, an unlock key is given to a specific manager such as a maintenance worker or a building manager so that the landing door can be opened from the landing side when necessary (Japanese Utility Model Publication No. 53-96761).

[Problem that the invention seeks to solve]

Opening and closing of the landing door from the landing side using the above-mentioned unlock key is done using the second door.
As shown in Figure 0, if the passenger door 12 is located opposite the landing door 1 where you are trying to get 1g1, there will be no problem with the stationery to open the landing door 1, but if the passenger door 12 is located opposite the landing door 1, then Even though it's not.

If the passenger thinks that the passenger car 12 is stopped on the other side of the landing door 1 and opens the landing door 1 after unlocking, the passenger may accidentally fall into the hoistway 20 and be seriously injured. This requires a lot of force when landing door 1 begins to open, and once it opens! When the door is opened, it takes a small amount of force to open it, so if the door is opened with too much force, the person's upper body will be caught and fall into the hoistway 20.

The present invention addresses the above-mentioned problems, and its purpose is to provide an elevator landing entrance that allows the presence or absence of a car to be checked from the first landing side and allows the door to be opened carefully. The goal is to provide equipment.

c. Means for Solving Problems] In order to achieve the above object, the present invention provides a display device near the first landing door to display the presence or absence of the first car.

Further, a detection hole 7 passing through the inside and outside of the landing door 1 is provided in the vicinity thereof, and a lens 8 is fitted into the detection hole 7.

On the other hand, a lamp 10 is provided at a position facing the detection hole of the car door 9 on the first and twelfth sides.

This car door 9 also has an upper end suspended from a door rail 12R via a hanger 11, and a lower end engaged with a sill 125.

The lamp 10 has a circuit structure that turns on when the passenger car 12 stops at the landing floor and enters a predetermined stopping zone, and a cover 10a is provided to prevent the light from being diffused. I am trying to illuminate door 1. The lens (concave) 8 allows the light of the lamp 10 to be confirmed through the detection hole 7 even if one landing type winding occurs.

With this configuration, when inserting the unlocking key 6 into the lock hole 5 during maintenance and inspection, if you look into the detection hole 7, you will be able to see if it will be inserted there.
You can know whether there is or not.

That is, if there is a power of 1 and 12, the detection hole 7 will be bright due to the light from the lamp 10, and if there is no power of 1 and 12, the detection hole 7 will be dark, so it is possible to confirm the presence or absence of the power of 1 and 12.

Therefore, when opening the landing door 1, if the passenger seat 12 has not landed on the floor, the door must be opened carefully, and accidents of falling into the hoistway can be avoided.

However, in the above embodiment, the detection hole 7 is provided in the vicinity of the lock hole 5 of the landing door 1, but if it is desired to avoid installing unnecessary things on the landing door 1 as much as possible, it is possible to install the detection hole 7 as shown in FIGS. 4 and 5. The presence or absence of a car may be confirmed using such a configuration. 4 and 5, a recess 13G is provided in the ceiling frame 13 forming the landing entrance 4, and a floodlight lamp 14 is housed in the recess 13G.
4 has a circuit configuration similar to the previous embodiment, so that the light is turned on when the driver and driver 12 enter a predetermined stop zone. 4, the landing door 1 is illuminated with a floodlight 14, and the fifth @ is to illuminate the landing floor F to confirm the presence or absence of the landing door 12. When the landing surface F is illuminated, it means that the passenger car seats 12 are on the floor. Further, the blinking of the floodlight lamp 14 can also bring about a change in a deserted boarding area.

Fig. 6 shows that light 15A from the landing side is introduced through the detection hole 7 of the landing door 1, and is reflected by the reflection plate 16 provided on the car door 9.The presence or absence of the reflected light 15B indicates whether the passenger has landed on the floor. This is to check if there is.

It is advantageous in that it does not require any special equipment. but.

If the lighting on the landing side is dark or if the detection hole 7 cannot be enlarged, install a lamp 17 on the back side of the landing door 1 as shown in FIG.
What is necessary is to provide a camera and check the reflected light.

By the way, in the above embodiment, landing of the car on the floor is confirmed by looking through the detection hole 7 or by illuminating the area around the first landing door. However, if special processing is not desired on the front side of the landing door 1, as shown in FIG.

The key guide 5G in the lock hole 5 is made of a light-transmitting material (for example, acrylic resin), and a lamp 1o is provided on the car door 9 facing the key guide 5G, so that the key guide 5G is illuminated when the car is in the car. The light is illuminated to confirm the presence or absence of a car.

Next, in FIGS. 9 to 11, a confirmation device 18 is provided near the lock hole 5 of the landing door 1. This confirmation device 18 is
A display body 19 capable of displaying a "basket dot", a 'basket bar' or a color-coded display is attached to the hole provided in the hole, and corresponding lamps 20A, 20B are provided behind the display to confirm whether the car has landed on the floor. This allows you to see at a glance whether or not there is a first-power car.

FIG. 12 shows a car door 1 in which a light spot such as a light emitting diode 21 is flashed toward the door surface in the vicinity of the lock hole 5.

Furthermore, in FIG. 13, the area around the landing door 1 seen from the landing side is exactly the same as the conventional shape, but there is a lamp 2 on the car 12 side.
2A and 22B are provided, and these lamps illuminate the gap between the landing door 1 and the landing entrance 4 to confirm the presence or absence of the car 12.

Incidentally, among the above-mentioned embodiments, the lamps and light emitting diodes that light up may be turned on when the car lands on the floor, or when the unlock key is inserted into the lock hole. Good too.

In each of the embodiments described above, the presence or absence of a car has been confirmed using an optical display device, but it goes without saying that confirmation can also be made using an audio display device. That is, in FIGS. 14 and 15, a sound device b! is installed inside the ceiling frame 13 forming the landing entrance/exit of each floor. Ls1* Sze 5a-
8N is installed, and the presence or absence of a passenger car is confirmed by vocalization or buzzer sound. Each sound device ll S 1 ” S N
and the power supply E are connected to the floor switch normally open contact F1”F.
N and door lock switch normally open contacts DI to DN are connected in series. And the floor switch normally open contact F! ~
FN is closed when the car enters the destination floor zone,
When the unlock key is inserted into the lock hole 5 of the landing door 1 on that floor, the normally open contacts D1 to DN of the door lock switch are closed and the sounding devices Sr to SN are activated. Since the sound device does not operate when the heel is not on the floor, it is possible to confirm whether there is a car or not. Conversely, when the first car is not on the target floor, the sound device
Alternatively, the SN may be activated.

By the way, in the above embodiment, the sounding device 8 is installed in the ceiling frame of the landing entrance.
1 to SN, but in this case, a large number of sounding devices must be installed in multi-story buildings, which is uneconomical. For this reason, as shown in Figures 16 and 17, one sound system is used! i! Sc may be attached to the passenger seat 12. Note that the arrangement and operation of the floor switch normally open contacts Fz"Fs and the door lock normally open contacts D1 to DN are the same as in the previous embodiment.

Next, FIGS. 18 and 19 show a display device formed using the sill 3 on the landing side. In FIG. 18, a storage case 23 is attached to the bottom of the sill 3 and a lamp 24 is stored inside. On the other hand, a hole is provided in the housing 3 that passes through the top and bottom, and a light-transmitting display member 25 is fitted into the hole. Then, when a car is in the landing zone (or not in the landing zone), the light is turned on to confirm the presence or absence of the first car. If the light is turned on only when landing on the car, it is possible to ventilate the area around the feet of general passengers when getting on and off the car. On the other hand, Figure 19 shows storage case 2.
A sound device W126 and a speaker 26S are housed inside the vehicle, and the presence or absence of a passenger car can be confirmed by sound or buzzer sound from the foot of the car.

In this case, it is preferable to operate the lock when the unlock key is inserted into the lock hole.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to check whether the passenger car is on the floor or not before opening the fifth landing door by installing simple parts, so that the opening of the first landing door can be carried out. Opening one door can prevent accidental falls into the hoistway during work.
