DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment will be described with reference to the drawings. Note that elements common to the various drawings are given the same reference numerals and redundant explanations will be omitted.

[0010] Embodiment 1. Elevator equipment configuration FIG. 1 is a diagram illustrating an overview of an elevator to which an elevator device according to this embodiment is applied. FIG. 2 is a functional block diagram illustrating the control configuration of the elevator device according to this embodiment. The elevator device 10 according to this embodiment is a device that notifies users standing in front of the hall doors of the elevator 100 in advance that the hall doors will open. The elevator 100 is installed in a facility consisting of a building or the like having multiple floors.

[0011] A hoistway 3 for an elevator 100 is provided in a facility. The hoistway 3 is a long space extending vertically across multiple floors. A landing 4 for the elevator 100 is provided on each floor of the facility. The landing 4 is located adjacent to the hoistway 3. A landing door 8 is provided at the landing entrance / exit of the landing 4 on each floor. The landing door 8 is a door that separates the landing 4 from the hoistway 3. The landing door 8 is, for example, of a center-opening type in which two panels open and close left and right, with the center of the landing entrance / exit in the left-right direction as the door closed position. The landing door 8 may also be of a single-wing type in which two panels open and close left and right, with the door closed position at the right or left end of the landing entrance / exit as the starting point.

[0012] The elevator 100 comprises a car 1, a control panel 6, a door operating device 12, and an object detection sensor 14. The car 1 is a device that transports passengers and others inside between multiple floors by traveling up and down a hoistway 3. The car 1 is equipped with a pair of car doors 2 at the car entrance that can be opened and closed in the left-right direction. The car doors 2 are either a center-opening type or a single-opening type, the same type as the hall doors 8.

[0013] When the car 1 stops at any floor, the car door 2 is opened and closed in conjunction with the hall door 8 of the hall 4 of that floor by the door opening and closing device 12 so that passengers can get on and off at the hall 4 of that floor and at the car 1. There are no limitations on the configuration of the door opening and closing device 12. The door opening and closing device 12 may be configured to mechanically engage and link the hall door 8 with the car door 2, or may be configured to electrically link and open and close the respective doors.

[0014] The object detection sensor 14 is a non-contact sensor that detects an object approaching the hall door 8 at the hall 4. There are no limitations on the configuration of the object detection sensor 14. For example, the object detection sensor 14 can be configured to have a light emitter having a light-emitting surface and a camera that captures an image of the light-emitting surface, arranged so as to straddle the hall entrance in the left-right direction. The object detection sensor 14 can detect the presence or absence of a user in the area near the hall door 8 at the hall 4. A detection signal from the object detection sensor 14 is sent to the control panel 6.

[0015] The control panel 6 is a device that controls the operation of the elevator 100. The control panel 6 is part of the control device 50 of the elevator system 10 of this embodiment. The operation of the elevator 100 controlled by the control panel 6 includes, for example, the opening and closing operation of the door opening and closing device 12, management of registered calls, and running of the car 1 in response to calls.

[0016] The elevator device 10 according to this embodiment includes a speaker device 20, a push-out mechanism 30, and a speaker control unit 40 in addition to the configuration of the elevator 100 described above.

[0017] The speaker device 20 is a device for making announcements to users by audio output. Fig. 3 is a perspective view seen through the car 1 moving in the hoistway 3. Fig. 4 is a perspective view seen through the car 1 in the hoistway 3 stopped at the landing 4. Fig. 5 is a cross-sectional schematic view of the elevator device 10 of Fig. 4 cut along a vertical plane passing through the central axis A of the speaker device 20. Fig. 6 is a diagram showing the configuration of the speaker device 20 and the push-out mechanism 30.

[0018] The speaker device 20 is installed on the panel back surface 2a of the car door 2 of the car 1, which is exposed to the elevator shaft 3. There are no limitations on the number of speaker devices 20 and their arrangement on the panel back surface 2a. In the example shown in the figure, a speaker device 20 is installed on the panel back surface 2a of each of the two panels of the car door 2. The speaker device 20 is arranged in a direction that outputs sound toward the panel back surface 8a of the hall door 8 that faces the panel back surface 2a of the car door 2 when the car 1 is in a hall stop state where it is stopped at the hall 4.

[0019] The speaker device 20 contains a diaphragm 22, a moving coil 23, and a permanent magnet 24 housed inside a cylindrical enclosure 21 with a bottom. The moving coil 23 is disposed at the center of the cylindrical permanent magnet 24. When a current corresponding to an audio signal flows through the moving coil 23, the moving coil 23 becomes an electromagnet and vibrates. The diaphragm 22 is connected to the moving coil 23, and emits the vibrations of the moving coil 23 into space as sound waves.

[0020] The enclosure 21 and the diaphragm 22 are open toward the rear panel surface 8a of the landing door 8. The diaphragm 22 is exposed from the opening. It is desirable that the enclosure 21 and the diaphragm 22 be made of a highly weather-resistant material and have a sealed structure so that they can withstand the installation environment of the elevator.

[0021] The opening edge 21a at the tip end of the enclosure 21 and the panel back surface 8a are spaced apart by a reference distance L. The reference distance L is set to a distance at which the opening edge 21a of the enclosure 21 does not come into contact with other parts in the hoistway 3 when the car 1 moves within the hoistway 3.

[0022] The push-out mechanism 30 is a device that moves the speaker device 20 in a horizontal movement direction toward the panel back surface 8a of the hall door 8 when the hall is stopped. The push-out mechanism 30 is arranged between the base end side of the enclosure 21 of the speaker device 20 and the panel back surface of the car door 2. The push-out mechanism 30 includes a case 31, a screw fastener 32, and a motor 33. The case 31 is a cylindrical part that houses the screw fastener 32 and the motor 33, and has a base end side fixed to the panel back surface 2a of the car door 2. The screw fastener 32 is screwed into the tip end side of the case 31. The tip end side of the screw fastener 32 is fixed to the base end side of the enclosure 21 of the speaker device 20. The base end side of the screw fastener 32 is connected to the rotation shaft of the motor 33 so as to be able to transmit rotational power.

[0023] When the motor 33 is rotated clockwise, the screw part 32 is rotated. As a result, the speaker device 20 is pushed out toward the panel back surface 8a of the landing door 8. In other words, the pushing mechanism 30 converts the rotational motion of the motor 33 into linear motion in the axial direction of the screw part 32. When the opening edge part 21a on the tip side of the enclosure 21 comes into contact with the panel back surface 8a of the landing door 8, the panel back surface 8a of the landing door 8 functions as a second diaphragm.

[0024] On the other hand, when the motor 33 is rotated counterclockwise, the screw part 32 is rotated in the reverse direction. As a result, the speaker device 20 is pushed back toward the panel back surface 2a of the car door 2, and the opening edge portion 21a on the tip side of the enclosure 21 moves away from the panel back surface 8a of the landing door 8. This enables the car 1 to move up and down within the hoistway 3.

[0025] The speaker control unit 40 is a part of the control device 50 of the elevator device 10. The speaker control unit 40 controls the operation of the speaker device 20 and the push mechanism 30. The speaker control unit 40 instructs the speaker device 20 to output a door-opening announcement to notify users at the landing 4 in advance of the door-opening operation of the landing door 8. Examples of the door-opening announcement include "The door is opening" and "Please move away from the door." The door-opening announcement may be, for example, a buzzer sound.

[0026] Alternatively, the speaker control unit 40 instructs the speaker device 20 to output a door closing announcement to notify users at the landing 4 in advance of the closing operation of the landing door 8. Examples of the door closing announcement include "The door is closing" and "Please move away from the door." The door closing announcement may be, for example, a buzzer sound.

[0027] Furthermore, the speaker control unit 40 controls the supply of electricity to the motor 33 of the push-out mechanism 30. Specifically, the speaker control unit 40 supplies a current for rotating the motor 33 forward when pushing out the speaker device 20, and supplies a current for rotating the motor 33 in the reverse direction when pushing back the speaker device 20.

[0028] 2. Features of the elevator equipment Next, a characteristic operation of the elevator device 10 of this embodiment will be described. When the car 1 arrives at the destination floor, the control panel 6 drives the door opening and closing device 12 to open the car doors 2 and the landing doors 8 in conjunction with each other. This operation will be hereinafter referred to as the "door opening operation." Furthermore, upon receiving a door closing command after the door opening operation, the control panel 6 drives the door opening and closing device 12 to close the car doors 2 and the landing doors 8 in conjunction with each other. This operation will be hereinafter referred to as the "door closing operation."

[0029] If no audio output device is installed at each landing, audio announcements cannot be made to users at each landing. In this case, users at the elevator landing 4 may not notice the door opening or closing. As a result, there is a risk that belongings of users near the landing door 8 may be pulled into the gap when the door opens or closes.

[0030] Therefore, the elevator device 10 of this embodiment makes an audio announcement from the car 1 to the users at the hall 4. Specifically, when the car 1 arrives at the hall 4 at the destination floor, the elevator device 10 makes an audio announcement to the users at the hall 4 before executing the door-opening operation. This operation is hereinafter referred to as the "pre-door-opening notification operation." Furthermore, when the car 1 departs from the hall 4, the elevator device 10 makes an audio announcement to the users at the hall 4 before executing the door-closing operation. This operation is hereinafter referred to as the "pre-door-closing notification operation." The pre-door-opening notification operation and the pre-door-closing notification operation will be described in more detail.

[0031] 2-1. Door opening warning operation When the car 1 arrives at the landing 4 at the destination floor, the panel back surface 2a of the car door 2 faces the panel back surface 8a of the landing door 8. Before starting the door-opening operation, the speaker control unit 40 drives the push-out mechanism 30 to push out the speaker device 20 toward the panel back surface 8a of the landing door 8. This operation will be referred to as the "push-out operation" hereinafter.

[0032] The pushing operation is performed until the opening edge portion 21a of the enclosure 21 of the speaker device 20 comes into contact with the panel back surface 8a of the landing door 8. As a result, the panel back surface 8a of the landing door 8 functions as a second diaphragm that transmits sound to the landing 4. In the door-opening warning operation, the speaker control unit 40 makes the speaker device 20 emit a door-opening announcement to notify in advance of the door-opening operation of the landing door 8. According to the door-opening warning operation, the landing door 8 as a second diaphragm can be used as a pseudo speaker to transmit the door-opening announcement to users at the landing 4. In addition, since the landing door 8 vibrates as a second diaphragm, it is possible to alert users leaning against the landing door 8 or users with hearing impairments by vibration, for example.

[0033] If the object detection sensor 14 detects an object after the door pre-opening notification operation is performed, there is a high possibility that a user or a user's belongings are near the landing door 8. Therefore, the speaker control unit 40 performs the door pre-opening notification operation again if the object detection sensor 14 detects an object after the door pre-opening notification operation is performed.

[0034] 2-2. Door closing warning operation In the pre-door-closing notification operation, the speaker control unit 40 makes the speaker device 20 emit a door-closing announcement to notify in advance of the door-closing operation of the landing door 8 before the door-closing operation starts.

[0035] If the object detection sensor 14 detects an object after the door-pre-closing notification operation is performed, there is a high possibility that a user or the user's belongings are near the landing door 8. Therefore, in the door-pre-closing notification operation, the speaker control unit 40 performs the door-pre-closing notification operation again if the object detection sensor 14 detects an object after the door-pre-closing notification operation is performed. Also, if the object detection sensor 14 detects an object during the door-closing operation, the speaker control unit 40 stops the door-closing operation and performs the door-opening operation. This operation is hereinafter referred to as the "door-opening reversal operation."

[0036] When the door closing operation is completed, the speaker control unit 40 drives the push-out mechanism 30 to push back the speaker device 20 toward the panel rear surface 2a of the car door 2. This operation will be referred to hereinafter as the "push-back operation."

[0037] The push-back operation is performed until the distance between the opening edge 21a of the enclosure 21 of the speaker device 20 and the panel back surface 8a of the landing door 8 exceeds the reference distance L. This makes it possible to prevent the opening edge 21a of the enclosure 21 from coming into contact with other parts in the elevator shaft 3 when the car 1 moves in the elevator shaft 3.

[0038] 3. Specific processing executed in the elevator device Next, specific processing executed in the elevator apparatus 10 will be described with reference to a flowchart. Fig. 7 is a flowchart of the pre-door-opening notification operation executed in the control device 50 of the elevator apparatus 10. In step S100, it is determined whether the elevator has arrived at the hall 4 of the destination floor based on the detection results of various sensors installed in the elevator 100. As a result, if the determination is not established, the process returns to step S100 again, and if the determination is established, the process proceeds to step S102.

[0039] In step S102, the speaker control unit 40 of the control device 50 outputs an operation command to perform a push-out operation to the push-out mechanism 30. Upon receiving the operation command, the push-out mechanism 30 moves the speaker device 20 in the horizontal movement direction until it contacts the panel back surface 8a of the landing door 8. After the process of step S102 is performed, the process proceeds to step S104.

[0040] In step S104, the speaker control unit 40 of the control device 50 outputs an operation command for a door-open announcement operation to the speaker device 20. Upon receiving the operation command, the speaker device 20 issues a door-open announcement.

[0041] After the process of step S104 is executed, the process proceeds to step S106. In step S106, it is determined whether the door opening operation can be started. Here, it is determined whether the object detection sensor 14 has detected an object. As a result, if the determination is not established, the process proceeds to step S108, and if the determination is established, the process proceeds to step S110.

[0042] In step S108, the speaker control unit 40 of the control device 50 again outputs an operation command for the door-open announcement operation to the speaker device 20. The speaker device 20 that has received the operation command again issues the door-open announcement. When the process of step S108 is completed, the process returns to step S106 again.

[0043] In step S110, the control panel 6 of the control device 50 executes the door-opening operation with the speaker device 20 in contact with the panel back surface 8a of the landing door 8. When the processing of step S110 is completed, this routine is ended.

[0044] Fig. 8 is a flowchart of the door-close pre-announcement operation executed by the control device 50 of the elevator device 10. The routine of Fig. 8 is executed upon receiving an operation command for the door-closing operation after the door-opening operation of the elevator 100. In step S120, the speaker control unit 40 of the control device 50 outputs an operation command for the door-close pre-announcement operation to the speaker device 20. Upon receiving the operation command, the speaker device 20 sounds a door-close announcement.

[0045] After the process of step S120 is executed, the process proceeds to step S122. In step S106, it is determined whether the door closing operation can be started. Here, it is determined whether the object detection sensor 14 has detected an object. As a result, if the determination is not established, the process proceeds to step S124, and if the determination is established, the process proceeds to step S126.

[0046] In step S124, the speaker control unit 40 of the control device 50 again outputs an operation command for the door pre-closing notification operation to the speaker device 20. The speaker device 20 that has received the operation command again sounds the door closing announcement. When the process of step S124 is completed, the process returns to step S122 again.

[0047] In step S126, the control panel 6 of the control device 50 executes the door closing operation with the speaker device 20 in contact with the panel back surface 8a of the landing door 8. In step S128, it is determined whether or not the object detection sensor 14 has detected an object during the door closing operation. As a result, if it is determined that the determination is true, the process proceeds to step S130, and if it is determined that the determination is false, the process proceeds to step S132.

[0048] In step S130, the control panel 6 of the control device 50 executes the reversing door-opening operation with the speaker device 20 in contact with the panel back surface 8a of the landing door 8. After the processing of step S130 is executed, the processing returns to step S120 again.

[0049] In step S132, the speaker control unit 40 of the control device 50 outputs an operation command to perform a push-back operation to the push-out mechanism 30. Upon receiving the operation command, the push-out mechanism 30 moves the speaker device 20 in the horizontal movement direction until the opening edge portion 21a of the speaker device 20 is separated from the panel back surface 8a of the landing door 8 by the reference distance L or more. When the processing of step S132 is performed, this routine is ended.

[0050] As is clear from the above description, according to the elevator system 10 of the present embodiment, it is possible to make an advance announcement of the opening of the landing doors to users at each landing without providing a speaker device at each of the multiple landings.

[0051] Furthermore, according to the elevator device 10 of this embodiment, the landing door 8 vibrates as a second vibrating plate, so that it is possible to alert, for example, a user leaning against the landing door 8 or a hearing-impaired user by vibration.

[0052] Moreover, according to the elevator device 10 of the present embodiment, the door-opening operation and the door-closing operation are performed with the speaker device 20 in contact with the rear panel surface 8a of the landing door 8. This makes it possible to sound an announcement toward the landing 4 while the door-opening operation or the door-closing operation is being performed.

[0053] 4.Modifications of elevator equipment The elevator device 10 according to the present embodiment may be modified as follows.

[0054] 4-1. Functional layout of the control device 50 There is no limitation on the location of the functions of the control device 50. In other words, some or all of the functions of the speaker control section 40 included in the control device 50 may be located on the control panel 6.
