Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) This invention relates to a home elevator installed in a private residence, and particularly relates to a rescue device for when a passenger is trapped in a car. It is something.

(Prior Art) In recent years, elevators have been installed in private residences as a measure for physically disabled and elderly people, or as a measure for residential land use. This elevator is called a home elevator.

On the other hand, with the spread of electronics, microcomputers have come to be widely used as elevator control devices.

Although the reliability of these control devices has certainly improved, it cannot be said that there are no unexplained failures caused by noise or the like.

If the control device malfunctions, the elevator may stop midway between floors, resulting in a so-called jamming failure, where passengers are trapped. In the event of such a jamming failure, an automatic recovery function provided in advance in the control device is activated to safely rescue passengers.

(Problem to be Solved by the Invention) However, if the automatic recovery function of the control device does not operate, rescue work by a specialized maintenance worker from an elevator maintenance company is required. This notification to the elevator maintenance company is made by an external notification device inside the car, but if the entrance is locked even when maintenance personnel arrive, it will take time to rescue the elevator. This will be explained using FIG. 5.

In the figure, an elevator 1 is provided inside a house 3. Suppose that this elevator 1 breaks down and a crushing failure occurs in which passengers are trapped in the car IC.

Assume that when this breakdown occurs, the elevator maintenance company is contacted through the notification device in the car IC or the telephone in the house, and the maintenance worker 4 actually arrives at the front door.

At this time, if other family members are at home, the lock 2 on the door 2d can be unlocked, so the maintenance worker 4 can enter the house 3 and carry out the rescue work.

However, if the other family members are absent and the door 2d is locked, the maintenance person 4 cannot enter the house 3 even if he/she arrives.

The reality is that almost all windows and entrances in modern houses are locked for security reasons, which makes it extremely difficult to enter the house and poses an obstacle to rescuing passengers in elevators.

In such cases, they have no choice but to either break a window and gain entry, or wait for other family members to return home. However, both of these methods are time consuming and can be extremely problematic, especially if the suffocated passenger is a sick person or a child.

One possible solution to this problem would be to ask a maintenance company to entrust and manage the duplicate key for lock 2, but from a safety perspective, entrusting the front door key to a private residence to a third party is not recommended. It's not good for both parties.

This invention was made to solve the above problems, and aims to provide a rescue device for a home elevator that enables quick rescue operations for passengers inside the elevator even when there are no other family members in the house. purpose.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a reporting means that can report from inside the car to a predetermined service organization outside the residence, and a failure detection means that detects a failure in which a passenger is trapped in the car. and an unlocking switch provided in the car so that passengers can operate it at any time, and the failure detection means outputting an unlocking command on the condition that a failure is detected and the unlocking switch is turned on. The present invention is characterized by comprising an unlocking command means for issuing an unlock command, and an unlocking means for unlocking an entrance to the house in response to the unlock command.

(Function) In this invention, if the unlock switch is turned on after the notification is made from inside the car to the outside of the house and before the house maintenance personnel arrive, the doorway to the house will be unlocked. Personnel can quickly enter the interior of the house and quickly rescue passengers inside the elevator.

(Embodiment) FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In the figure, a descending operation command relay (not shown),
A failure detection device 11 detects a failure of the elevator 1 based on the status of the ascending operation command relay, start detection relay, door open command relay, door close detection relay, etc., and automatically reports to the maintenance company 5 based on this failure detection signal. an unlocking switch 14 that can be operated by a passenger at any time to unlock the doorway, and an unlocking command that issues an unlocking command on the condition that the unlocking switch 14 is turned on when a failure is detected. An unlock command device 15 for outputting the lock is provided on the in-car operation panel 6 of the elevator 1. Residential entrance/exit part 2 such as entrance
is provided with an electric unlocking device 17 and an unlocking detection device 18 that detects unlocking and sends a confirmation signal back to the unlocking command device 15. On the other hand, the maintenance company 5 is equipped with a receiving device 21 that receives information from the failure transmitting device 12 and a recording device bag 22 that records the received contents.

FIG. 2 is a relay circuit diagram showing the detailed structure of the unlock command device 15. Here, a failure detection device 1 is installed between the DC power bus R and 7, which is maintained uninterrupted even in the event of a power outage of the commercial power supply.
1. Unlock output relay 31, unlock detection relay 18R1 The electric lock solenoid coil 17c of the unlock device 17 is connected.

Among these, the unlock output relay 31 has a failure detection device 11.
The failure detection contact 11a1 of the mode changeover switch 13, the unlocking switch 14, and the b contact 18b of the unlocking detection relay 18R are connected in series. In this case, the common contact terminal C of the mode changeover switch 13 is connected to the unlock switch 14 and the contact 1
The contact terminal on the normally closed side of the mode changeover switch 13 is connected to the unlock output relay 31 through
The normally open contact terminal a of the mode changeover switch 13 is directly connected to the DC power supply bus R via 1a.

Furthermore, the unlock detection limit switch 18S of the unlock detection device J8 is connected in series to the unlock detection relay 18R, and the unlock output relay 31 a is connected to the electric lock solenoid coil 17c.
The contacts 31a are connected in series.

FIG. 3 is a relay circuit diagram showing the detailed configuration of the failure detection device 11. This device is a failure detection time relay that performs delay operation between the DC power supply bus 211. is connected, and a parallel circuit of the a contact 41 of the descending operation command relay and the a contact 42 of the ascending operation command relay and the b contact 43 of the start detection relay are connected in series to this failure detection time relay = 11H, Furthermore, these contact circuits include a series circuit of the a contact 44a of the door open command relay and the a contact 45a of the door close detection relay, and the b contact 44 of the door open command relay.
b and the series circuit of the b contact 45b of the door close detection relay are connected in parallel.

FIG. 4 is a front view of the in-car operation panel 6, in which a door open button switch 7 and a door close button switch 8 are arranged on the left and right at the top. Below that, a destination call button switch 9 is arranged vertically. Then, at the bottom of °C1, a mode changeover switch 13 and an unlock switch 14 are arranged on the left and right,
Since these are to be operated in an emergency, they are covered with a sliding lid [6].

The operation of the sixth embodiment configured as described above will be described below.

First, relatively serious failures, including passenger jamming failures, include elevators not starting even though the control device has issued an ascending or descending operation command, and doors not starting even though a door opening command has been issued. If the door does not open or the door does not close even though a door close command has been output for a certain period of time or more, the failure detection device 1fLL determines that there is a failure and outputs a failure detection signal. In response to this failure detection signal, the failure transmission device 12 transmits a failure occurrence signal to the maintenance company 5 using, for example, a telephone line.

At the maintenance company, the receiving device 21 receives this signal, records it in the recording device 22, and notifies the maintenance personnel. Therefore, a maintenance worker from maintenance company 5 is dispatched to the relevant residence.

On the other hand, the passenger trapped in the elevator 1 opens the sliding lid 16 of the in-car operation panel 6 (FIG. 4) and presses the unlock switch 14. As a result, the unlocking command device 15 receives the failure detection signal of the failure detection device 11 and the unlocking switch 1.
4 on-operation signal is added. The unlocking command device 15 operates the unlocking device 17 of the house entrance/exit section 2 on the condition that both of these signals are applied. Then, the unlocking detection device 18 detects that the lock is unlocked and sends it to the unlocking command device 15 to restore the state.

Next, the detailed operation of the unlock command device 15 will be explained using FIG. 2. When the failure detection device 11 detects a failure, the failure detection contact 11a is closed. In addition, since the mode selector switch 13 is normally connected to the b terminal side,
When a passenger in the car turns on the unlock switch 14, the unlock output relay 31 is energized. This unlock output relay 3
1, the contact 31a is closed and the electric lock solenoid coil 17c is energized. As a result, an actuator (not shown) of the electric lock is activated by electromagnetic attraction, and the lock is moved from the locked side to the unlocked side. In other words, it is unlocked.

On the other hand, the limit switch 18s is closed by the movement of the actuator, and the unlock detection relay 18R is energized. This energization of the unlock detection relay 18H causes its contact 18b to open. Therefore, even if the unlock switch 14 continues to be pressed, the unlock output relay 31 becomes de-energized at this point, and overheating can be prevented.

Here, if the cause of the failure is removed by the maintenance personnel's rescue work, the failure detection device 11 is restored and the failure detection contact 11a is opened, thereby completing the restoration work.

By the way, suppose that while the elevator is in use, passengers are trapped due to a cause other than a malfunction, such as a power outage.

At this time, the control device does not operate and the failure detection device 11 also does not operate, making unlocking impossible. The mode selector switch 13 is operated under such circumstances, and if you switch it to the special side and connect it to the terminal a side, then press the unlock switch 14, the series of operations will be performed in the same way as described above. The unlocking operation is performed.

Next, the detailed operation of the failure detection device 11 will be explained using FIG. When a descending operation command is issued to the elevator, the a contact 41 of the descending operation command relay is closed, and when an ascending operation command is issued, the a contact 42 of the ascending operation command relay is closed. On the other hand, if the elevator starts, the b contact 43 of the start detection relay
is open. Therefore, the failure detection time relay 11R is energized from the time the ascending operation command or the descending operation command is issued until it is actually activated. However, since this failure detection time relay 11R operates on-delay for only 30 seconds, it will not operate unless this state continues for 30 seconds or more. As a result, a failure is detected when the engine does not start even after 30 seconds have elapsed since the descending operation command or the ascending operation command was issued.

Similarly, when a door open command is issued, the door open command relay a
Even though the contact 44a is closed, if the a contact 45a of the door close detection relay remains closed for 30 seconds or more while the door is closed, it will still be detected as a failure.

Furthermore, the b contact 44b of the door open command relay, which was opened by the door open command, is not actually closed even though it is closed by the door close command, so the b contact 45b of the door close detection relay is not closed. If the condition continues for more than 30 seconds, it is also considered a failure.

Therefore, the failure detection device 11 can generate a failure detection signal by exciting the failure detection time relay 11R and opening the contact 11a in the event of a serious failure including a single failure.

According to this embodiment, the door is unlocked by pressing the unlock switch 14 in the event of a jamming failure, so maintenance personnel who arrive upon notification can immediately carry out rescue work.

Further, the unlocking of the entrance/exit is not only conditioned on the pressing of the unlock switch 14, but also on the failure detection operation of the failure detection device 11, thereby preventing unnecessary unlocking other than when a failure occurs. be able to.

Furthermore, since the mode changeover switch 13 is provided, the lock can be unlocked even if the lock is locked due to a reason other than a failure of the control device.

Furthermore, since the unlock detection limit switch 18S is provided to de-energize the unlock output relay 31 after unlocking, it is possible to prevent the unlock output relay 31 from overheating, and a small one can be used as the unlock output relay 31. .

In the above embodiment, the unlock switch 14 is provided on the in-car operation panel 6, but it may be provided in any other suitable location within the car.

Further, in the above embodiment, the failure transmitting device 12 is installed in the car.
Although the maintenance company 5 is provided with a receiving device 21 and a recording device 22, a regular telephone may be used instead.

Furthermore, in the above embodiment, the unlocking device is used exclusively for elevator failures, but it goes without saying that this unlocking device may be operated from other sources.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, the user can make a report by simply turning on the unlock switch in anticipation of the arrival of maintenance personnel by making a report to a designated service organization outside the residence from inside the car. Maintenance personnel who arrive can quickly carry out rescue work.
