Disclosure of Invention

Problems to be solved by the invention

When an intercom call button (emergency call button) provided in the car is operated, the elevator is operated to an alarm device that notifies the outside of occurrence of an emergency, and is placed in a state of being able to communicate with the outside through a car speaker and a microphone. The power supply for operating the intercom call button and the intercom (speaker and microphone) uses a battery as a backup power supply that can be operated even when power is cut. As in the technology described in patent document 1, a talk-back call button, a speaker, and a microphone generally operate on a common battery. Therefore, in the technique described in patent document 1, when the battery is exhausted due to the continued use of the intercom button and the intercom (speaker and microphone), these devices are no longer usable, and the alarm device linked to the emergency call button is no longer operable. When the alarm device linked to the emergency call button is no longer operable, there is a possibility that passengers enclosed in the car become uneasy.

The invention aims to provide an elevator device which can enable an alarm device linked with an intercom calling button to work even if an intercom can no longer be used.

Means for solving the problems

In order to achieve the above object, the present invention provides an elevator apparatus comprising: a car that can be lifted and lowered in a hoistway; a traction machine for lifting the car; a talk-back call button arranged on the car; an intercom provided in the car and operating in response to an operation of the intercom call button; an alarm device provided in the car and operated in response to an operation of the intercom call button; a battery for the intercom call button for supplying power to the intercom call button and the alarm device; and a battery for interphone for supplying power to the interphone, wherein the power supply capacity of the battery for interphone call button is larger than that of the battery for interphone.

Effects of the invention

According to the present invention, it is possible to provide an elevator apparatus capable of operating an alarm device linked to an intercom call button even when the intercom is no longer usable.

Example 1

Fig. 1 is a front view of the elevator apparatus of embodiment 1, and fig. 2 is a schematic view of the elevator apparatus of embodiment 1.

The elevator apparatus 1 is provided with an elevator landing 10 at each floor. There are three boxes 11 at the landing of the elevator landing 10. The three-party frame is arranged at the upper part and the left and right parts of the boarding and disembarking opening. The frame is not present in the lower part of the three frames, thereby eliminating the height difference due to the frame and improving the riding quality for the car of the elevator apparatus 1. Because there is no difference in height, it is particularly effective for wheelchair and scooter access. A door 12 for opening and closing the entrance is attached to the three-part frame 11. The elevator hall 10 is provided with an alarm device 14 (first alarm device) for giving an alarm by an operation of an intercom call button 44 described later.

On the side of the door 12 there is a call button 13 for calling the car.

The elevator apparatus 1 includes a car 20 on which passengers ride, a wire rope 21 having one end connected to the car 20, a counterweight 22 connected to the other end of the wire rope 21, and a hoisting machine 23 for driving and rotating a sheave around which the wire rope 21 is wound to raise and lower the car 20. The car 20 is lifted and lowered in the hoistway by a hoisting machine 23 via a wire rope 21. The elevator apparatus 1 further includes a control device 24 that transmits and receives signals to and from the car 20, supplies electric power, and controls the hoisting machine 23, devices provided in the car 20, and the like. The car 20 is electrically connected to the control device 24 via a tail cable 25.

Further, in the upper part of the car 20, there are provided a battery 26 for an intercom call button for supplying power to an intercom call button 44 (fig. 4) when the car 20 is stopped in an emergency, a battery 27 for an intercom for supplying power to a speaker 48 and a microphone 49 constituting an intercom 41 (fig. 4), and an alarm device 28 (second alarm device) for giving an alarm by operation of the intercom call button 44. As described in detail later, embodiment 1 is characterized by having an intercom call button battery 26 for supplying power to the intercom call button 44 and the alarm devices 14 and 28, in addition to the intercom battery 27. The elevator apparatus 1 of embodiment 1 is connected to a remote monitoring center 29 via a control device 24 and is remotely monitored.

In example 1, since the car 20 has the intercom battery 26 and the intercom battery 27, the installation of 2 batteries is easy.

Next, the structure in the car will be described. Fig. 3 is a front view of the car of example 1. The periphery of the car 20 is covered with a top wall 31, a bottom wall 32, and side walls 33, 34. The front surface of the car 20 has a car door 35 for passengers to get in and out, and an in-car operation panel 36 disposed laterally of the car door 35.

The structure of the in-car operation panel 36 will be described with reference to fig. 4. Fig. 4 is a schematic view of an in-car operation panel of embodiment 1.

In fig. 4, the in-car operation panel 36 includes a display device 40, an intercom 41, a destination floor button 42 for inputting a destination floor to a passenger, an opening/closing button 43 for instructing opening/closing operation of the car door 35, and an intercom call button 44 for activating the intercom 41 for connecting the passenger enclosed in the car 20 to the remote monitoring center 29 and operating the alarm device 28 provided in the car 20 and the alarm device 14 provided in the elevator hall 10 of each floor at the time of emergency stop of the car.

The display device 40 includes a lift display unit 45 that indicates the lift direction of the car 20, a car position display unit 46 that indicates the position of the car 20, and a message display unit 47 that displays a message when the car 20 is stopped in an emergency.

The intercom 41 has a speaker 48 and a microphone 49 for performing a conversation with the remote monitoring center 29. When the intercom call button 44 is pressed, the intercom 41 is connected to the remote monitoring center 29, and can communicate with the remote monitoring center 29 using the speaker 48 and the microphone 49.

Next, the configuration of the intercom system will be described with reference to fig. 5. Fig. 5 is a diagram showing a connection relationship between the intercom system and the battery in example 1.

In fig. 5, the intercom system 50 of embodiment 1 is constituted by an intercom 41 and an intercom call button 44.

The intercom 41 is connected to the intercom battery 27, and is a power source for operating a speaker 48 and a microphone 49 constituting the intercom 41. The intercom call button 44 is connected to the intercom call button battery 26, and is a power source for operating the alarm devices 14 and 28 linked to the intercom call button 44. The intercom 41 is interlocked with the intercom call button 44, and the intercom 41 can be operated by pressing the intercom call button 44. The alarm device 14 is an alarm device provided in the elevator hall 10, and power supplied from the battery 26 for the intercom call button to the alarm device 14 is supplied via the tail cable 25 and the control device 24.

In embodiment 1, the power supply for operating the intercom 41 is configured separately from the power supply for operating the intercom call button 44 and the alarm devices 14 and 28. The power supply capacity of the intercom battery 26 is set to be larger than the power supply capacity of the intercom battery 27.

When the car 20 is stopped in an emergency and enclosed in the car 20, passengers wait for rescue in the enclosed car 20 until the longer the time for rescue is, the more passengers are not safe. When a call can be made with the remote monitoring center 29 through the intercom 41, the passenger's anxiety is alleviated to some extent, but when the battery for the intercom 41 to operate is exhausted and the means for notifying the outside is broken, the passenger considers that the passenger himself or herself is enclosed in the car 20 to be forgotten, and the anxiety increases.

In example 1, the intercom battery 26 is provided in addition to the intercom battery 27, and the power supply capacity of the intercom battery 26 is set to be larger than the power supply capacity of the intercom battery 27. In embodiment 1, even when the intercom battery 27 is exhausted and the intercom 41 is no longer available for communication between the car 20 and the remote monitoring center 29, the power supply from the intercom call button 44 battery 26 can be provided by pressing the intercom call button 44, and the alarm devices 14 and 28 can be operated, so that the passenger enclosed in the car 20 can notify himself or herself of the presence, and the anxiety can be alleviated.

The above-described flow is described next with reference to fig. 6. Fig. 6 is a flowchart of the process when the car 20 is stopped abnormally. The control device 24 monitors whether the talk over call button 44 in the car 20 is pressed.

The control device 24 determines whether or not the talk back call button 44 in the car 20 is pressed (step S601). When the talk back call button 44 is pressed (yes in step S601), the flow proceeds to step S602. If the talk back button 44 is not pressed (no in step S601), the process in step S601 is repeated.

In step S602, when the charge capacity of the intercom button battery 26 is sufficient (yes in step S602), the flow proceeds to step S603. When the charge capacity of the battery 26 for the intercom call button is insufficient (no in step S602), the process ends.

In step S603, the control device 24 receives power supply from the battery 26 for the intercom call button, and activates the alarm devices 14 and 28 provided in the elevator hall 10 and the car 20. An alarm sound sounds in the elevator hall 10 and the car 20. In addition, by pressing the intercom call button 44, the intercom 41 can operate. After that, the process advances to step S604.

In step S604, the control device 24 reports to the remote monitoring center 29 that the intercom call button 44 is pressed. After that, the process advances to step S605.

In step S605, when the charge capacity of the battery 27 for interphone is sufficient (yes in step S605), the passenger communicates with the remote monitoring center 29 using the speaker 48 and the microphone 49. After that, the process advances to step S606. If the charge capacity of the battery 27 for interphone is insufficient (no in step S605), the process proceeds to step S607.

In step S606, the passenger waits until a response is received from the remote monitoring center 29. When receiving the response from the remote monitoring center 29 (yes in step S606), the process proceeds to step S607. If no response is received from the remote monitoring center 29 (no in step S606), the process in step S605 is performed again.

In step S607, the control device 24 monitors whether or not a stop instruction is issued from the remote monitoring center 29 to the alarm devices 14 and 28, and when the stop instruction is issued (yes in step S607), the flow proceeds to step S608, and the operation of the alarm devices 14 and 28 is stopped. If the stop instruction is not issued (no in step S607), the process in step S607 is repeated. The process of step S607 can be executed irrespective of the charge capacity of the battery 27 for interphone.

When the passenger enclosed in the car 20 presses the intercom button 44 again after the alarm device 14, 28 stops in step S608, the process of step S601 is repeated.

In example 1, as described above, the intercom battery 26 is provided in addition to the intercom battery 27, and the power supply capacity of the intercom battery 26 is set to be larger than the power supply capacity of the intercom battery 27. Therefore, even when the charge capacity of the intercom battery 27 is exhausted, the alarm devices 14 and 28 can be operated.

Even when the charge capacity of the battery 27 for interphone is exhausted, the information that the talk-back call button 44 is pressed is transmitted to the remote monitoring center 29, and the remote monitoring center 29 can stop the alarm devices 14 and 28 regardless of the charge capacity of the battery 27 for interphone.

Further, after the alarm devices 14 and 28 are stopped, when the passenger enclosed in the car 20 presses the talk back call button 44 again, the alarm devices 14 and 28 are operated by supplying power from the talk back call button battery 26.

In this embodiment, even when the charge capacity of the intercom battery 27 is exhausted, when the intercom button 44 is pressed, the alarm devices 14 and 28 can be operated by supplying power from the intercom button battery 26, so that the passenger's anxiety in the car 20 can be alleviated.

Example 2

Next, embodiment 2 of the present invention will be described with reference to fig. 7. Fig. 7 is a schematic view of the elevator apparatus of embodiment 2. The same reference numerals are given to the same structures as those of embodiment 1, and detailed description thereof is omitted.

In embodiment 2, the point different from embodiment 1 is the installation position of the battery 26 for the talk back call button.

In example 1, the battery 26 for the intercom call button is disposed on the car 20, but in example 2, the battery 26 for the intercom call button is disposed in the control device 24.

As in embodiment 1, the car 20 and the control device 24 are connected by a tail cable 25.

An intercom battery 27 for supplying power to a speaker 48 and a microphone 49 constituting an intercom 41 (fig. 4), and an alarm device 28 for giving an alarm by an operation of an intercom call button 44 are provided at an upper portion of the car 20.

The control device 24 includes a battery 26 for an intercom call button that supplies power to an intercom call button 44 (fig. 4) when the car 20 is stopped in an emergency.

In example 2, as in example 1, an intercom call button battery 26 for supplying power to an intercom call button 44 is provided in addition to the intercom battery 27. The power supply capacity of the intercom battery 26 is set to be larger than the power supply capacity of the intercom battery 27.

By pressing the intercom call button 44, the intercom 41 is supplied with power from the intercom battery 27, and can be operated. When the intercom button 44 is pressed, the battery 26 for intercom button provided in the control device 24 supplies power to the alarm device 14, and also supplies power to the alarm device 28 via the tail cable 25 to give an alarm.

According to embodiment 2, even when the intercom battery 27 is exhausted and the car 20 and the remote monitoring center 29 can no longer communicate with each other through the intercom 41, the power supply from the intercom call button 44 battery 26 can be made to operate the alarm devices 14 and 28 by pressing the intercom call button 44, so that the passenger enclosed in the car 20 can notify himself or herself of the presence, and the anxiety can be alleviated.

In addition, in embodiment 2, since the intercom call button battery 26 having a larger power supply capacity than the intercom battery 27 is provided in the control device 24, the weight of the car 20 can be reduced, and the load applied to the wire rope 21 can be reduced. Further, since the weight of the car 20 can be reduced, the driving load of the hoisting machine 23 can be reduced, and energy saving can be achieved.

The present invention is not limited to the above-described embodiments, and includes various modifications. The above-described embodiments are described in detail for the purpose of easily understanding the present invention, and are not limited to the configuration in which all the descriptions are necessarily provided.
