Description

  The present invention relates to an elevator apparatus, and more particularly to an elevator apparatus that can use a car as a disaster prevention shelter when a disaster such as an earthquake, a fire, or radioactive contamination occurs.

  Disaster prevention shelters are known in which users of buildings evacuate in the event of a disaster such as an earthquake or fire. For example, as a technique for using a bathroom as a fireproof shelter in the event of a fire, the surrounding wall of the bathroom has a two-layer structure, and a water supply member and water supply piping for water spraying are arranged between the inner layer and the outer layer, respectively. There has been disclosed a technique for constructing a fire wall by sprinkling water from a water supply pipe sometimes to fill the wall with water (see Patent Document 1).

  On the other hand, for example, disaster prevention shelters for protecting themselves against accidental accidents such as nuclear facilities and radioactive contamination in the event of an emergency are rarely used in Japan due to problems such as installation space and installation costs.

  On the other hand, for example, an attempt to use an elevator car as a shelter as a facility installed in a building has been studied. For example, an elevator car such as a private house is used as a security shelter, the car door has a flameproof and bulletproof structure, and a mechanism that locks the car door to prevent it from opening inside the car An elevator for emergency evacuation provided with a wireless communication device is disclosed (see Patent Document 2).

Japanese Patent Laid-Open No. 4-155077 Japanese Patent Laid-Open No. 2005-194063

  However, for example, when a disaster such as a fire or an earthquake occurs in a high-rise building, the conventional elevator moves to the refuge floor etc. and opens the door, and then when the set time elapses, it closes again and waits. It is mandatory. In other words, a car that is in a standby state on a refuge floor or the like is invalidated to open the door, and may not be able to evacuate into the car even if the user performs the door opening operation from the outside. .

  For example, depending on the fall of rubble in the elevator hoistway at the time of an earthquake, the high temperature around the platform at the time of a fire, the radiation level at the time of radioactive contamination, etc. Even if it is used, the function as a disaster prevention shelter may not be fully exhibited due to the structure of the car. Furthermore, when a car breaks down in the event of a disaster and a user is trapped in the car for a long time, there is a risk of suffering in terms of hunger and excretion.

  This invention makes it a subject to provide the elevator apparatus which can function the inside of a passenger car as a disaster prevention shelter at the time of disasters, such as an earthquake, a fire, and radioactive contamination.

  In order to solve the above-mentioned problems, an elevator apparatus according to the present invention includes a car configured to have a disaster prevention shelter function, lifting means for raising and lowering the car, and door opening and closing means for opening and closing the car door. And a disaster detection means for detecting a disaster, and a control means for controlling the lifting means and the opening / closing means. The control means moves the car to the set floor based on the disaster detection signal of the disaster detection means. When the operation button provided outside the car is operated, the car is opened when the operation button provided on the outside of the car is operated, and when the operation button inside the car opened is operated, or when the set time elapses, It is characterized by controlling the car to be closed.

  According to such a configuration, when a disaster occurs, the user can operate the car waiting on the set floor from the outside to open the door, enter the car, and then close the door again. Therefore, the inside of the car can be used as a disaster prevention shelter, and the safety of the user can be ensured.

  In this case, the car shall have at least one of a heat-resistant structure, an earthquake-resistant structure, and a radiation shielding structure. These structures can be realized, for example, by configuring the surrounding wall or door of the car with a well-known fireproof panel, impact-resistant reinforcing member, radiation shielding panel, or the like.

  Moreover, it is preferable that the car is provided with a reporting means for reporting to the outside. According to this, for example, the presence of a user in the car can be reported to the disaster prevention center, etc., so that the user can confirm the safety from the outside and recover from the car until it is rescued. Can be used as a disaster prevention shelter.

  The disaster detection means has detection means for detecting at least one of a physical quantity representing the magnitude of an earthquake, a temperature outside the car, and a radiation dose outside the car, and is based on a detection signal of the detection means. Informing means for informing the detection information in the car is provided. According to this, the user in the car can grasp the disaster situation outside the car, and can notify the detection information to the outside by the reporting means if necessary.

  Further, the control means may perform control so that the car door opening operation is invalid based on the detection information. According to this, since the inside of the car can be completely isolated from the external disaster environment, the safety of the users in the car can be ensured.

  Further, it is preferable that the car is provided with at least one of an openable and closable stored food storage container and an openable and filthy storage container on the inner surface of the car. According to this, even if the user is confined in the car for a long time, the pain associated with thirst, hunger and excretion can be alleviated.

  According to the elevator apparatus of the present invention, the car can function as a disaster prevention shelter during disasters such as earthquakes, fires, and radioactive contamination.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a configuration diagram of an elevator apparatus to which the present invention is applied. The elevator apparatus according to the present embodiment is adapted to any disaster such as a fire, an earthquake, and radioactive contamination, and can cause the car 1 to function as a disaster prevention shelter by performing predetermined control.

  The elevator apparatus of this embodiment includes a car 1, a controller 3, an automatic notification device 5, a seismic intensity detector 7, a temperature detector 9, and a radiation detector 11.

  The controller 3 is installed in the upper part of the car 1, and incorporates a microcomputer 13 that functions as a central processing unit. The microcomputer 13 configures various functions necessary for operating the elevator by a program.

  In the platform of the car 1, a seismic intensity detector 7 for detecting the magnitude of the earthquake, a temperature detector 9 for detecting the temperature of the platform, and a radiation detector 11 for detecting the radiation level of the platform are installed. These are all electrically connected to the controller 3, and the detection signals detected by the detectors are respectively input to the controller 3. A call button 10 for the car 1 is installed on the wall of the platform.

  A fireproof structure, an earthquake resistant structure, and a radiation shielding structure are applied to part or all of the side wall, floor surface, door, and ceiling surface of the car 1, for example, a heat resistant material 17 (fireproof tile, etc.) and a radiation shielding material 19 ( A high strength member having a predetermined strength against external impact or the like is incorporated as a reinforcing member.

  A seismic intensity indicator lamp 21, a temperature indicator lamp 23, and a radiation indicator lamp 25 are installed in the car 1, and detection signals output from the seismic intensity detector 7, the temperature detector 9, and the radiation detector 11 are provided in these. The seismic intensity detection value, the temperature detection value, and the radiation detection value are respectively displayed via the controller 3. An operation panel 15 in which a destination floor button, a door opening / closing button, and the like are disposed is installed in the car 1, and the operation panel 15 is electrically connected to the controller 3.

  A stored food storage box 27 is stored in the back of the door in the side wall of the car 1, and for example, stored food for two weeks is stored here. In addition, a filth storage box 29 for storing filth is stored under the door in the floor of the car 1.

  The automatic notification device 5 is electrically connected to the controller 3 and, as will be described later, when a disaster occurs, for example, the presence of a user in the car 1 is automatically notified to an external disaster prevention center. report. Moreover, the automatic reporting device 5 reports the detection signals of the seismic intensity detection value, the temperature detection value, and the radiation detection value output from the controller 3 to the disaster prevention center.

  Next, the operation of the elevator apparatus configured as described above will be described. FIG. 2 is a flowchart for explaining an example of the operation in the elevator apparatus to which the present invention is applied.

  For example, when an earthquake occurs while the car 1 is moving up and down and the seismic intensity detector 7 detects a seismic intensity detection value that is greater than or equal to the set value, the controller 3 causes the operation control of the car 1 to start a disaster from the normal operation mode. Switch to operation mode. Thereby, for example, the car 1 moves to the nearest floor and stops, and the door 31 is opened. At this time, the seismic intensity detection value detected by the seismic intensity detector 7 is displayed on the seismic intensity indicator lamp 21 in the car 1. When the set time elapses after the door 31 is opened, the car 1 closes the door 31 by a door closing signal from the controller 3 and enters a standby state (step S1).

  Next, the car 1 is set when the temperature detection value is detected by the temperature detector 9 in the standby state in step 1 or when the seismic intensity detection value by the seismic intensity detector 7 is less than the set value. While moving to the accused floor and stopping, the door 31 is opened. At this time, the temperature detection value detected by the temperature detector 9 is displayed on the temperature indicator lamp 23 in the car 1. When the set time elapses after the door 31 is opened, the car 1 closes the door 31 by a door closing signal from the controller 3 and enters a standby state (step S2).

  Next, in the standby state of step 1 or 2, or when the detection values by the seismic intensity detector 7 and the temperature detector 9 are both less than or equal to the set values, the radiation detector 11 detects a radiation detection value greater than or equal to the set value. The car 1 moves to the set refuge floor and stops, and the door 31 is opened. At this time, a radiation detection value detected by the radiation detector 11 is displayed on the radiation indicator lamp 25 in the car 1. When the set time elapses after the door 31 is opened, the car 1 closes the door 31 by a door closing signal from the controller 3 and enters a standby state (step S3).

  In Steps S1 to S3, when none of the detectors can detect a disaster, or even when at least one disaster is detected and a standby state is established, if a predetermined safety level is secured after that, The operation control of the car 1 is switched to the normal operation mode and returned to step S1 (step S4).

  On the other hand, when the landing call button 10 is pressed by the user in the standby state of steps S <b> 1 to S <b> 3, the car 1 opens the door 31 again by a door open signal from the controller 3. When the user enters the car 1 with the door 31 open and the door close button on the operation panel 15 is pressed, the car 1 closes the door 3 by a door close signal from the controller 3 and the disaster prevention shelter. It becomes. At this time, for example, the presence of the user in the car 1, and information on the detected values detected by the seismic intensity detector 7, the temperature detector 9, and the radiation detector 11 are automatically notified to an external disaster prevention center. It should be noted that the door 31 of the car 1 may be controlled so that the door is automatically closed when the set time has passed without the user pressing the door closing button in the car 1 (step S5).

  In step S5, the car 1 functioning as a disaster prevention shelter has detected values of the seismic intensity detector 7, the temperature detector 9, and the radiation detector 11 that are equal to or higher than a set value after the user gets into the car 1. When the danger value is reached, the door opening operation from inside and outside the car 1 can be invalidated. According to this, since the disaster prevention center can secure a disaster prevention shelter that blocks the inside of the car from the outside until the door 31 is opened after the external safety is secured, Can be secured.

  And when these detection values fall and satisfy a certain safety standard, the door opening operation can be switched effectively and the door 31 of the car 1 can be opened. Moreover, various detection values can be reported to the disaster prevention center one after another, and the door opening operation can be performed by remote operation from the disaster prevention center based on the detection values.

  By the way, the user is confined in the car 1 until personal safety is ensured. For example, in the case of radioactive contamination, when the radiation detection value is 10,000 X-rays, it takes about two weeks for the radioactivity to be reduced to 1/1000 and to ensure a certain level of safety. Meanwhile, since the user is confined in the car 1 for a long time, the problem of hunger, thirst and excretion may occur, which may cause pain. Therefore, a stored food storage box 27 and a filth storage box 29 are installed in the car 1, for example, about 2 weeks of stored food is stored in the stored food storage box 27, and portable paper diapers are stored. Keep it. According to this, since excrement etc. can be stored in the filth storage box 29, a user's pain can be eased.

  As described above, according to the present embodiment, when the disaster occurs, the car 1 is moved to a safe floor to be on standby, and can be evacuated into the car 1 by the operation of the user. Safety is confirmed and restored from outside by automatic notification, and the car 1 can be used as a disaster prevention shelter until the passenger is rescued, thus ensuring the safety of users who encounter earthquakes, fires and nuclear disasters. be able to.

  In the present embodiment, an example in which the seismic intensity detector 7, the temperature detector 9, and the radiation detector 11 are each installed at one place on the elevator landing is described. However, the present invention is not limited to this example. You may make it install in a location.

It is a block diagram of the elevator apparatus with which this invention is applied. It is a flowchart explaining an example of operation | movement of the elevator apparatus with which this invention is applied.
