[0003] JP 2014-73890 A

[0004] When performing maintenance on elevator shaft equipment installed in an elevator shaft, maintenance workers may become so engrossed in searching for things invisible to the human eye, such as abnormal noises, that they may not notice other elevator shaft equipment approaching overhead. In light of this background, if it were possible to make it difficult for maintenance workers to approach other elevator shaft equipment even while concentrating on maintaining the elevator shaft equipment, not only would it be possible to achieve the significant effect of increasing the safety of the maintenance workers, but it would also be possible to create an environment in which the maintenance workers could concentrate on maintenance, enabling high-quality maintenance to be performed efficiently. Therefore, an object of the present disclosure is to provide an elevator that makes it difficult for maintenance workers to approach elevator shaft equipment, thereby increasing the safety of the maintenance workers.

[0005] In order to solve the above problems, the elevator of the present disclosure includes one or more elevator shaft devices that are arranged in an elevator shaft and whose vertical distance from the car changes as the car moves, a detection device attached to the elevator shaft devices, and a control device that receives information from the detection device, wherein the detection device is capable of detecting a physical quantity that can identify a car deceleration start state in which at least a part of a person is in a specified area below the elevator shaft device to which it is attached, and when the control device receives information based on the physical quantity that corresponds to the car deceleration start state detected by at least one of the detection devices, it controls the car to decelerate its moving speed.

[0006] The predetermined lower area may be, for example, a detection area of ​​a detection device attached to the lower side of the elevator shaft equipment, or an area within the detection area of ​​the detection device attached to the lower side of the elevator shaft equipment where the vertical distance from the lower end of the elevator shaft equipment to the lower side is equal to or less than a predetermined distance. Alternatively, the predetermined lower area may be an area that satisfies the following conditions: it includes all areas where the horizontal distance between the person (maintenance worker) and the elevator shaft equipment is equal to or less than a first predetermined distance, but it does not include all areas where the horizontal distance between the person and the elevator shaft equipment is equal to or greater than a second predetermined distance (> the first predetermined area), and it does not include all areas where the vertical distance from the lower end of the elevator shaft equipment to the lower side is equal to or less than a predetermined distance.

[0007] According to the present disclosure, when the car enters a car deceleration start state in which at least a part of a person has entered a predetermined area below the elevator shaft equipment, the moving speed of the car decelerates. Therefore, by setting (matching) the predetermined area below to an area where there is a risk of people approaching the elevator shaft equipment, it is possible to prevent people from approaching the elevator shaft equipment, thereby increasing the safety of people.

[0008] The predetermined area may include an area whose distance in the height direction from a lower end of the elevator shaft equipment to a lower side is equal to or less than a predetermined distance and which overlaps with the elevator shaft equipment in the height direction.

[0009] With this configuration, the car always decelerates when conditions make it particularly likely for people to get close to the elevator shaft equipment. This further increases human safety. Furthermore, because high human safety can be guaranteed, it becomes possible to check even the smallest details that could not be checked in current maintenance, enabling more thorough maintenance. Furthermore, because it is possible to check even the smallest details that could not be checked before, points discovered during maintenance can be used in the design of new elevators, leading to a reduction in malfunctions in new elevators. Furthermore, maintenance can be performed quickly and efficiently, reducing the burden on people.

[0010] The one or more detection devices may include at least one of a first detection device attached to the counterweight and a second detection device attached to the guide plate.

[0011] The horizontal distance between the guide plate and the counterweight is relatively short, making them prone to come close to people performing maintenance work on the car. There is also a risk that the counterweight may come close to people working in the pit.

[0012] According to the above configuration, proximity between elevator shaft equipment and people can be effectively prevented.

[0013] The one or more elevator shaft pieces of equipment may include the counterweight having a spacer provided on the underside thereof, and the first detection device may be attached to the spacer.

[0014] According to this configuration, the first detection device can be easily fixed to the counterweight using the spacer.

[0015] The first detection device may be attachable to both one side of the spacer in the width direction and the other side of the spacer in the width direction.

[0016] If an object is present in a position that interferes with the light or radio waves output by the first detection device to detect a person, false detection is likely to occur.

[0017] According to this configuration, the first detection device can be attached to both sides of the spacer in the width direction, so that the first detection device can be fixed to the side that is less likely to cause erroneous detection based on the arrangement of objects in the elevator shaft for each elevator specification, making it easier to detect people with high accuracy.

[0018] The detection device may be detachable from the elevator shaft equipment, and the detection device and the control device may communicate wirelessly.

[0019] If the detector is permanently installed, there is a risk that it may malfunction and cause disruption to normal operation. Furthermore, if the detector is permanently installed, the running costs will be high.

[0020] According to this configuration, the detection device is detachable from the elevator shaft equipment, so it can be installed in the elevator shaft only during elevator shaft maintenance and inspection. Therefore, malfunctions of the detection device do not interfere with normal operation, and elevator running costs can be reduced. Furthermore, wireless communication between the detection device and the control device allows for greater flexibility in the installation location of the detection device. This facilitates highly accurate detection and makes installation of the detection device simple.

[0021] Furthermore, the control device may stop the car when it receives information based on the physical quantity corresponding to the car deceleration start state detected by at least one of the detection devices.

[0022] According to the above configuration, the safety of people can be further improved.

[0023] In addition, the control device may determine whether to perform control to slow down the car's movement speed only when the car is in a maintenance and inspection mode in which it does not move, based on a destination floor designation button installed inside the car.

[0024] According to this configuration, the car deceleration control of the present disclosure is not performed during normal operation when the maintenance inspection mode is not in effect, thereby preventing the car deceleration control from being performed due to a malfunction during normal operation.

[0025] In addition, the control device can determine, based on the physical quantity, that the vertical distance is less than a second predetermined distance that is less than the predetermined distance, and is equipped with a sound output device, and when it determines that at least a portion of the person has entered an area that is included in the predetermined area and where the vertical distance is less than the second predetermined distance, the control device may cause the sound output device to output sound.

[0026] According to this configuration, for example, when at least a portion of a person enters the predetermined area after the vertical distance from the bottom of the elevator shaft equipment to a person below the elevator shaft equipment becomes equal to or less than a second predetermined distance, or when at least a portion of a person remains in the predetermined area even after the car starts to decelerate and deceleration begins, the sound output device can output a warning sound or a message informing the person that they are approaching overhead elevator shaft equipment, such as "Please keep away from overhead elevator shaft equipment" or "Please immediately withdraw your head and hands." This ensures the safety of the person. In this case, the second predetermined distance may be the same as the predetermined distance or may be less than the predetermined distance.

[0027] Furthermore, the control device can determine, based on the physical quantity, that the vertical distance is equal to or less than a third predetermined distance that is longer than the predetermined distance, and is equipped with a sound output device, and when the control device determines that at least a portion of a person has entered a second predetermined area that includes an area that vertically overlaps with the elevator shaft equipment within a vertical range where the vertical distance is longer than the predetermined distance and less than the third predetermined distance, the control device may cause the sound output device to output a message instructing the user to be careful of the elevator shaft equipment above.

[0028] Possible phrases to indicate caution against overhead elevator equipment include, for example, "Be careful of overhead elevator equipment," and "If you continue like this, you will come into contact with elevator equipment."

[0029] This configuration can further improve the safety of people, and can also prevent frequent car deceleration control, thereby improving the efficiency of maintenance and inspection work.

[0030] The sound output device may be integral with the detection device.

[0031] According to this configuration, the sound output device can be installed at the same time as the detection device, thereby improving convenience and ease of use. Furthermore, since the sound output device is disposed near the detection device, a sound to alert people can be output from near the elevator shaft equipment, which is the object that needs to be alerted to people's proximity. Therefore, the warning sound can be effectively and reliably conveyed to people, thereby significantly improving their safety.

[0032] According to the elevator of the present disclosure, people (maintenance workers) are less likely to approach the elevator shaft equipment, thereby increasing the safety of people.

[0034] Embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It is anticipated that, when multiple embodiments and variations are included below, new embodiments can be constructed by appropriately combining their characteristic features. In the following examples, identical components are designated by the same reference numerals in the drawings, and redundant description will be omitted. The drawings include schematic diagrams, and the dimensional ratios of the length, width, height, etc., of each component between different drawings do not necessarily match. In the following description and drawings, the X direction is the depth direction of the car 11 of the elevator 10, the Y direction is the width direction of the car 11, and the Z direction is the height direction of the car 11. The X direction, Y direction, and Z direction are perpendicular to each other. Among the components described below, components not recited in the independent claims representing the highest concept are optional components and not essential components.

[0035] FIG. 1 is a schematic diagram of an elevator 10 according to an embodiment of the present disclosure. As shown in FIG. 1 , the elevator 10 includes a car 11, a hoist 12, a counterweight 13, a wire rope 14, a car call button 15, a destination floor designation button 16, a landing position detection sensor 18, and a control panel 19 as a control device. The control panel 19 and the hoist 12 are provided in a machine room 30 above a hoistway 20. If the elevator does not have a machine room, the control panel and the hoist 12 are provided, for example, in a pit below the hoistway. The wire rope 14 is wound around the hoist 12, with one end fixed to the top of the car 11 and the other end fixed to the counterweight 13 via a deflector sheave (not shown). The car call button 15, which calls the car 11 and specifies the direction of travel of the car 11, is provided at each landing 22 on every floor. In addition, a destination floor designation button 16 is provided inside the car 11 for designating the destination floor of the car 11.

[0036] The control panel 19 includes a computer, such as a microcomputer, and includes a control unit and a memory unit. The control unit, i.e., the processor, includes, for example, a CPU (Central Processing Unit). The memory unit is configured with a hard disk drive (HDD), a solid state drive (SSD), or the like, and may include a nonvolatile memory, such as a ROM (Read Only Memory), and a volatile memory, such as a RAM (Random Access Memory). The memory unit may be configured with only one storage medium, or may be configured with multiple different storage media. The CPU reads and executes control programs and the like stored in the memory unit. The nonvolatile memory stores the control programs, predetermined thresholds, and the like in advance. The volatile memory temporarily stores the read control programs, processing data, and the like.

[0037] The car 11 and the counterweight 13 are each guided by a guide rail provided in the hoistway 20. A control panel 19 receives signals from the car call button 15 and the destination floor designation button 16 and appropriately controls the rotation speed and direction of the hoist motor 12a of the hoist 12, causing the car 11 to rise and fall in the hoistway 20. A landing position detection sensor 18 detects the landing position of a hall 22 at which the car 11 lands. The landing position detection sensor 18 includes, for example, a metal (e.g., iron) guide plate 18a installed in the hoistway 20 at a height position that allows the car 11 to stop at the landing position on each floor, and a magnetic detector 18b installed on the car 11 and that detects the guide plate 18a. The detector 18b detects the guide plate 18a. The control panel 19 receives a signal indicating that the detector 18b has detected the guide plate 18a and controls the hoist motor 12a, causing the car 11 to land at the floor for which the stop command was input. After that, the control panel 19 controls the car door motor (not shown), causing the car door 32 to open and the hall door 31 to open in conjunction with this, allowing people to get on and off the car 11.

[0038] The elevator 10 further includes one first detection device 35, one first sound output device 46, one first wireless communication device 51, multiple second detection devices 39, multiple second sound output devices 47, and multiple second wireless communication devices 52. The one first detection device 35, the one first sound output device 46, and the one first wireless communication device 51 are integrated together to form a first integrated device 55. The one second detection device 39, the one second sound output device 47, and the one second wireless communication device 52 are also integrated together to form a second integrated device 56. The number of second integrated devices 56 corresponds to the number of guide boards 18a provided corresponding to each floor. The first integrated devices 55 and the second integrated devices 56 are integrated using an integration means, such as one or more of a fastening means, an adhesive, and a welding joint.

[0039] The first integrating device 55 is fixed to the counterweight 13, which is an example of elevator shaft equipment, using a detachable structure. FIG. 2 is a front view of the counterweight 13, and FIGS. 3 and 4 are diagrams illustrating the fixing of the first integrating device 55 to the counterweight 13. As shown in FIG. 2, the counterweight 13 includes a frame 13b that fixes the wire rope 14 and houses multiple rod-shaped weights 13a, and a spacer 13c located below the frame 13b. The spacer 13c protrudes downward from the center in the Y direction of a lower frame portion 13d of the frame 13b. As shown in FIGS. 3 and 4, the first integrating device 55 is actually installed only on one side in the width direction (coincident with the Y direction), but can be attached to both one side and the other side of the spacer 13c in the width direction. Therefore, the first detection device 35 included in the first integration device 55 can also be attached to both one side in the width direction of the spacer 13c and the other side in the width direction of the spacer 13c.

[0040] Specifically, the spacer 13c has a first screw hole (not shown) with a bottom extending in the Y direction on a first side in the Y direction, and a second screw hole (not shown) with a bottom extending in the Y direction on a second side in the Y direction. The first screw hole is identical to the second screw hole. Each screw hole can receive a male screw (not shown) of a rod-shaped member 60 having a small-diameter rod-shaped portion (not shown) with a male screw at its tip. As shown in FIGS. 3 and 4 , when the male screw is fastened to the spacer 13c by being fastened to the screw hole of the spacer 13c, the rod-shaped member 60 extends in the Y direction. The rod-shaped member 60 has one or more screw holes with a bottom extending in the Y direction on its outer side surface in the Y direction. The first integrating device 55 also has one or more screw holes at its upper end that extend in the Y direction and penetrate the first integrating device 55. The male threads of bolts (screw members) (not shown) are fastened into the threaded holes of the first integrating device 55, and then fastened into the bottomed threaded holes of the rod-shaped member 60, thereby fixing the first integrating device 55 to the rod-shaped member 60 using one or more bolts. The first integrating device may have a permanent magnet, and may be fixed to the spacer 13c using a permanent magnet or a clip, or may be fixed to the rod-shaped member attached to the spacer 13c using a permanent magnet or a clip.

[0041] Meanwhile, the second integrating devices 56 are fixed, one by one, to a plurality of guide plates 18a provided corresponding to each floor using a detachable structure. The guide plates 18a are an example of elevator shaft equipment. FIGS. 5 and 6 are diagrams illustrating the fixing of the second integrating devices 56 to the guide plates 18a. As shown in FIGS. 5 and 6 , each guide plate 18a is attached at a predetermined height range in the elevator shaft 20. Each guide plate 18a has a plurality of through holes (elongated holes in this embodiment) 63 spaced apart in the Z direction for attaching the guide plate 18a to the elevator shaft 20. The second integrating device 56 also has one or more bottomed screw holes (not shown). The second integrating device 56 is fixed to the guide plate 18a using one or more bolts 68 by passing the shank of a bolt (screw member) through the through hole 63 and then tightening it into the screw hole of the second integrating device 56.

[0042] Each guide plate 18a may be attached to a wall portion on the landing side 22 in the X direction of the hoistway 20, or may be attached to a wall portion on the far side of the hoistway 20 in the X direction (opposite the landing 22 side). Alternatively, each guide plate 18a may be installed on one side in the width direction of the car 11, as described in JP-A-9-278299. Furthermore, the second integrating device may have a permanent magnet or a clip, and the second integrating device may be fixed to the guide plate 18a using the permanent magnet or the clip.

[0043] The first detection device 35 is configured to detect a physical quantity that can determine whether at least a portion of a person has entered a predetermined area below the first detection device 35. The first detection device 35 may include, for example, a millimeter-wave sensor, a LIDAR sensor, or an ultrasonic sensor. Here, the millimeter-wave sensor emits millimeter waves (electromagnetic waves with a wavelength of 1 to 10 mm) and can measure the distance to an obstacle and the direction of the obstacle based on the time it takes for the millimeter waves to reflect off the obstacle and return. The LIDAR sensor measures scattered light in response to irradiation with pulsed laser light and can detect the distance to a distant object and the direction of the object. The ultrasonic sensor emits ultrasonic waves toward the object using a transmitter and receives the reflected waves using a receiver, thereby detecting the presence or absence of the object and the distance to the object.

[0044] The first detection device 35 equipped with these sensors can freely adjust the detection area for a person by adjusting the installation position, the oscillation direction of the oscillating waves, the wavelength of the oscillating waves, the output power of the emitted waves, etc. For example, by appropriately adjusting these conditions, the first detection device 35 can set a predetermined area below the counterweight 13 as its detection area, and can set this predetermined area below to an area that satisfies the following conditions: the area includes all areas where the horizontal distance between the person (maintenance worker) and the counterweight 13 is less than a first predetermined distance, but does not include all areas where the horizontal distance between the person and the counterweight 13 is more than a second predetermined distance (> the first predetermined area), and the distance in the height direction (vertical direction) from the bottom end of the counterweight 13 to the lower side is less than a predetermined distance.

[0045] Here, for example, the first predetermined distance can be set to a length of 15 cm or more and 30 cm or less, and the second predetermined distance can be set to a length of 20 cm or more and 50 cm or less, regarding the horizontal distance between the person and the counterweight 13. Furthermore, for example, the predetermined distance can be set to a length of 1 m or more and 4 m or less, regarding the vertical distance from the lower end of the counterweight 13 to the lower side.

[0046] The first sound output device 46 also includes a voice generation unit that generates a synthesized sound and a speaker electrically connected to the voice generation unit. The voice generation unit generates the synthesized sound in response to a control signal from the control panel 19, and the generated synthesized sound is output from the speaker to the elevator shaft 20. The control panel 19 and the first wireless communication device 51 each have a wireless signal transceiver and perform wireless communication based on a wireless communication standard such as Bluetooth (registered trademark), Wi-Fi (registered trademark), or WiMAX. The first detection device 35 transmits detection information to the transceiver of the control panel 19 via the first wireless communication device 51. The control panel 19 also transmits a control signal to the first sound output device 46 via the transceiver and the first wireless communication device 51.

[0047] The second detection device 39 is configured to detect a physical quantity that can determine whether at least a portion of a person has entered a predetermined area below the second detection device 39. The second detection device 39 may include, for example, a millimeter wave sensor, a LIDAR sensor, or an ultrasonic sensor. The second detection device 39 can freely adjust its detection area by adjusting its installation position, the direction of oscillation of the oscillating waves, the wavelength of the oscillating waves, the output power of the emitted waves, and the like. By appropriately adjusting these conditions, the second detection device 39 can set the predetermined area below the guide board 18a as its detection area. For example, the second detection device 39 can match the predetermined area below the guide board 18a to an area that satisfies the following conditions: the area includes all areas where the horizontal distance between the person and the guide board 18a is less than a first predetermined distance, but excludes all areas where the horizontal distance between the person and the guide board 18a is greater than a second predetermined distance (> the first predetermined area); and the vertical distance from the bottom end of the guide board 18a to the lower side is less than a predetermined distance.

[0048] Here, for example, the first predetermined distance with respect to the horizontal distance between the person and the guide board 18a can be set to a length of 15 cm or more and 30 cm or less, and the second predetermined distance can be set to a length of 20 cm or more and 50 cm or less. Also, for example, the height distance from the bottom end of the guide board 18a to the lower side can be set to a length of 1 m or more and 4 m or less.

[0049] The second sound output device 47 also includes a voice generation unit that generates a synthesized sound and a speaker electrically connected to the voice generation unit. The voice generation unit generates the synthesized sound in response to a control signal from the control panel 19, and the generated synthesized sound is output from the speaker to the elevator shaft 20. The control panel 19 and the second wireless communication device 52 each have a wireless signal transceiver and perform wireless communication based on a wireless communication standard such as Bluetooth (registered trademark), Wi-Fi (registered trademark), or WiMAX. The second detection device 39 transmits detection information to the transceiver of the control panel 19 via the second wireless communication device 52. The control panel 19 also transmits a control signal to the second sound output device 47 via the transceiver and the second wireless communication device 52.

[0050] Fig. 7 is a schematic diagram for explaining a situation in which the first detection device 35 detects a person, and is a schematic diagram for explaining the transmission of a signal from the first detection device 35 to the control panel 19. Fig. 8 is a schematic diagram for explaining a situation in which the second detection device 39 detects a person, and is a schematic diagram for explaining the transmission of a signal from the second detection device 39 to the control panel 19.

[0051] If the predetermined area includes an area that overlaps the counterweight 13 in the height direction within the height direction of the predetermined area, for example, as illustrated in FIG. 7 , while the car 11 is ascending in the direction of arrow A during maintenance, if at least a portion of a person 80 enters the area that overlaps the counterweight 13 in the height direction and the height distance between the lower end of the counterweight 13 and the person 80 approaches a predetermined distance, the first detection device 35 detects that at least a portion of the person 80 has entered the predetermined distance. Then, a signal from the first detection device 35 is transmitted to the control unit of the control panel 19 via the first wireless communication device 51 and the transceiver 19a of the control panel 19, or a signal from the first detection device 35 is transmitted to the control unit of the control panel 19 via the first wireless communication device 51, a wireless repeater (not shown), and the transceiver 19a of the control panel 19. Based on this signal transmission, the control panel 19 determines that at least a portion of the person 80 has entered the predetermined area below the counterweight 13.

[0052] Furthermore, if the predetermined area includes an area that overlaps with the guide board 18a in the height direction within the predetermined area, for example, as illustrated in FIG. 8 , while the car 11 is ascending in the direction of arrow A during maintenance, if at least a portion of a person 80 enters the area that overlaps with the guide board 18a in the height direction and the vertical distance between the lower end of the guide board 18a and the person 80 approaches a predetermined distance, the second detection device 39 detects that at least a portion of the person 80 has entered the predetermined distance. Then, a signal from the second detection device 39 is transmitted to the control unit of the control panel 19 via the second wireless communication device 52 and the transceiver 19a of the control panel 19, or a signal from the second detection device 39 is transmitted to the control unit of the control panel 19 via the second wireless communication device 52, a wireless repeater (not shown), and the transceiver 19a of the control panel 19. Based on this signal transmission, the control panel 19 determines that at least a portion of the person 80 has entered the predetermined area below the guide board 18a. The elevator of the present disclosure does not necessarily have to include the sound output devices 46, 47. In this case, the wireless communication device 51 for transmitting a wireless signal based on the signal from the first detection device 35 to the control unit of the control panel 19 only needs to have a wireless signal transmitter, and the wireless communication device 52 for transmitting a wireless signal based on the signal from the second detection device 39 to the wireless communication device of the control panel 19 only needs to have a wireless signal transmitter. Furthermore, the wireless communication device of the control panel (control device) only needs to have a wireless signal receiver.

[0053] Next, an example of control that the control panel 19 performs to increase the safety of the person 80 based on information from the first detection device 35 will be described. Note that the control panel 19 can perform control similar to the control described below based on information from the second detection device 39, and a description of that control will be omitted with the description of the control that will be described next. Also, if the car 11 is decelerated based on the detection result of any one of the detection devices 35, 39 while the control described below is being performed using the first detection device 35 and all of the second detection devices 39, the control based on the detection results of the detection devices 35, 39 other than that one is terminated, and after the deceleration operation is completed, the control may be restarted from step S1.

[0054] 9 is an example of a flowchart illustrating an example of control performed by the control panel 19 of the elevator 10 to increase the safety of the person 80 by making it difficult for the person 80 to approach the counterweight 13. For example, when the mode of the elevator 10 is changed from a normal mode in which the raising and lowering of the car 11 is controlled based on the destination floor designation button 16, which is used by a person inside the car 11 to designate a destination floor for the car 11, to a maintenance and inspection mode in which the car 11 does not move based on the destination floor designation button 16, by operating a mode selection unit provided on the back side of the destination floor designation button 16, the control starts.

[0055] In step S1 after the start of control, the control panel 19 determines, based on information from the first detection device 35, whether at least a part of the person 80 has entered a second predetermined area including an area that overlaps vertically with the counterweight 13, within a vertical range in which the vertical distance from the lower end of the counterweight 13 downward is longer than a predetermined distance and less than a third predetermined distance.

[0056] If a positive determination is made in step S1, the process proceeds to step S2, where the control panel 19 causes the first sound output device 46 to output a message urging the user to be careful of the overhead counterweight 13, and then the process proceeds to step S3. Here, examples of messages urging the user to be careful of the overhead counterweight 13 include "Be careful of the overhead counterweight" and "If you continue like this, you will come into contact with the counterweight." On the other hand, if a negative determination is made in step S1, the process proceeds to step S3, where the control panel 19 determines, based on information from the first detection device 35, whether or not at least a part of the person 80 is present at a height included in a height range in which the height direction distance from the bottom end of the counterweight 13 downward is equal to or less than a predetermined distance.

[0057] If a negative determination is made in step S3, step S1 and subsequent steps are repeated. On the other hand, if a positive determination is made in step S3, the process proceeds to step S4, where the control panel 19 determines, based on information from the first detection device 35, whether at least a portion of the person 80 has entered a predetermined area below the counterweight 13. For example, the control panel 19 determines whether at least a portion of the person 80 has entered a predetermined area including an area overlapping the counterweight 13 in the height direction, within a height range where the height direction distance from the lower end of the counterweight 13 to the lower side is equal to or less than the predetermined distance. If a negative determination is made in step S4, the process proceeds to step S6. On the other hand, if a positive determination is made in step S4, the process proceeds to step S5, where the control panel 19 controls the hoist motor 12a to start a stopping operation of the car 11, and then the process proceeds to step S6.

[0058] In step S6, the control panel 19 determines, based on information from the first detection device 35, whether or not at least a part of the person 80 has entered an area that is included in the predetermined area and whose vertical distance is equal to or less than a second predetermined distance that is equal to or less than the predetermined distance. If a positive determination is made in step S6, the process proceeds to step S7, in which the control panel 19 causes the first sound output device 46 to output a message notifying the person 80 that they are about to come close to the overhead counterweight 13, and then the process proceeds to step S8. Examples of the message to be output in step S7 include "Please keep away from the overhead counterweight 13," or "Please immediately remove your head and hands."

[0059] On the other hand, if a negative determination is made in step S6, the process proceeds to step S8, where the control panel 19 determines, for example, based on information from an encoder (not shown), whether either the car 11 has stopped or the lower end of the counterweight 13 and the upper end of the car 11 are at the same height. If the encoder is an absolute encoder, it can detect the rotation distance from the origin of the hoist motor 12a of the hoist 12, and the positions of the car 11 and the counterweight 13 can be detected with high accuracy. The encoder may be of any of a mechanical (contact), optical, magnetic, and electromagnetic induction type.

[0060] If the determination in step S8 is negative, step S4 and subsequent steps are repeated. On the other hand, if the determination in step S8 is positive, control returns and step S1 is repeated. This control ends, for example, when the mode of the elevator 10 is changed by operation of the mode selection unit from a maintenance and inspection mode in which the car 11 does not move based on the destination floor designation button 16 to a normal mode in which the lifting and lowering of the car 11 is controlled based on the destination floor designation button 16, which is used by a person inside the car 11 to designate a destination floor for the car 11.

[0061] As described above, elevator 10 is arranged in elevator shaft 20 and comprises one or more elevator shaft pieces of equipment (balance weight 13, guide plate 18a) whose vertical distance from car 11 changes as car 11 moves, detection devices 35, 39 attached to elevator shaft pieces 13, 18a, and a control device (control panel 19) that receives information from detection devices 35, 39, wherein detection devices 35, 39 are capable of detecting physical quantities that can identify a car deceleration start state in which at least a part of person 80 has entered a specified area below elevator shaft piece 13, 18a to which they are attached, and when control panel 19 receives information based on the physical quantities corresponding to the car deceleration start state detected by at least one detection device 35, 39, it performs control to slow down the moving speed of car 11.

[0062] The predetermined lower area may be, for example, the detection area of ​​the detection device 35, 39 attached to the lower side of the elevator shaft equipment 13, 18a, or may be an area within the detection area of ​​the detection device 35, 39 attached to the lower side of the elevator shaft equipment 13, 18a where the vertical distance from the lower end of the elevator shaft equipment 13, 18a to the lower side is equal to or less than a predetermined distance. Alternatively, the predetermined lower area may be an area that satisfies the conditions that it includes all areas where the horizontal distance between the person 80 and the elevator shaft equipment 13, 18a is equal to or less than a first predetermined distance and excludes all areas where the horizontal distance between the person 80 and the elevator shaft equipment 13, 18a is equal to or greater than a second predetermined distance (> the first predetermined area), and that it excludes all areas where the vertical distance from the lower end of the elevator shaft equipment 13, 18a to the lower side is equal to or less than a predetermined distance.

[0063] According to the present disclosure, when the car deceleration start state is reached in which at least a part of the person 80 has entered a predetermined area below the elevator shaft equipment 13, 18a, the moving speed of the car 11 is decelerated. Therefore, by setting (matching) the predetermined area below to an area where the person 80 is likely to come close to the elevator shaft equipment 13, 18a, it is possible to prevent the person 80 from coming close to the elevator shaft equipment, thereby increasing the safety of the person 80.

[0064] The predetermined area may also include an area that is a predetermined distance or less in height direction from the lower end of the elevator shaft equipment 13, 18a downward and that overlaps with the elevator shaft equipment 13, 18a in the height direction.

[0065] According to this configuration, the car always decelerates when a person 80 is particularly likely to come close to the elevator shaft equipment 13, 18a. This further increases the safety of the person 80. Furthermore, since the high safety of the person 80 can be guaranteed, it becomes possible to check even the smallest details that could not be checked in current maintenance, enabling more thorough maintenance. Furthermore, because it is possible to check even the smallest details, points discovered during maintenance can be used in the design of new elevators, leading to a reduction in malfunctions in new elevators. Furthermore, maintenance can be performed quickly and efficiently, reducing the burden on the person 80.

[0066] The one or more detection devices may also include at least one of a first detection device 35 attached to the counterweight 13 and a second detection device 39 attached to the guide plate 18a.

[0067] The horizontal distance between the guide plate 18a and the counterweight 13 and the car 11 is relatively short, and they are likely to come close to a person 80 performing maintenance work on the car 11. There is also a risk that the counterweight 13 may come close to a person 80 working in the pit.

[0068] According to the above configuration, proximity between the elevator shaft equipment 13, 18a and the person 80 can be effectively prevented.

[0069] Additionally, one or more of the hoistway equipment 13, 18a may include a counterweight 13 having a spacer 13c on the underside thereof, and the first detection device 35 may be attached to the spacer 13c.

[0070] According to this configuration, the first detection device 35 can be easily fixed to the counterweight 13 using the spacer 13c.

[0071] Furthermore, the first detection device 35 may be attachable to both one side of the spacer 13c in the width direction and the other side of the spacer 13c in the width direction.

[0072] If an object is present in a position that interferes with the light or radio waves output by the first detection device 35 to detect the person 80, false detection is likely to occur.

[0073] According to this configuration, the first detection device 35 can be attached to both sides of the spacer 13c in the width direction, so that the first detection device 35 can be fixed to the side that is less likely to cause erroneous detection based on the arrangement of objects in the hoistway 20 for each specification of the elevator 10. This makes it easier to detect the person 80 with high accuracy.

[0074] Furthermore, the detection devices 35, 39 may be detachable from the elevator shaft equipment 13, 18a, and the detection devices 35, 39 and the control panel 19 may communicate wirelessly.

[0075] If the detectors 35 and 39 are permanently installed, there is a risk that malfunctions may cause disruption to normal operation. Furthermore, if the detectors 35 and 39 are permanently installed, the running costs will be high.

[0076] According to this configuration, the detection devices 35, 39 are detachable from the elevator shaft equipment 13, 18a, so the detection devices 35, 39 can be installed in the elevator shaft 20 only during maintenance and inspection of the elevator shaft 20. As a result, malfunction of the detection devices 35, 39 will not interfere with normal operation, and the running costs of the elevator 10 can be reduced. Furthermore, because the detection devices 35, 39 communicate wirelessly with the control panel 19, the installation position of the detection devices 35, 39 can be more freely selected. This makes it easier to perform detection with high accuracy, and the detection devices 35, 39 can be installed easily.

[0077] Furthermore, the control panel 19 may stop the car 11 when it receives information based on a physical quantity corresponding to the car deceleration start state detected by at least one of the detection devices 35, 39.

[0078] According to the above configuration, the safety of the person 80 can be further improved.

[0079] In addition, the control panel 19 may determine whether or not to perform control to slow down the movement speed of the car 11 only when the car 11 is in a maintenance inspection mode in which the car 11 does not move, based on the destination floor designation button 16 provided inside the car 11.

[0080] According to this configuration, the car deceleration control of the present disclosure is not performed during normal operation when the maintenance inspection mode is not in effect, thereby preventing the car deceleration control from being performed due to a malfunction during normal operation.

[0081] Furthermore, the control panel 19 can determine, based on the physical quantities detected by the detection devices 35, 39, that the vertical distance from the lower end of the elevator shaft equipment 13, 18a to the downward side is less than a second predetermined distance, which is less than a predetermined distance, and is equipped with sound output devices 46, 47, so that when it is determined that at least a part of the person 80 has entered an area that is included in the predetermined area and whose vertical distance is less than the second predetermined distance, the control panel 19 may cause the sound output devices 46, 47 to output a sound.

[0082] According to this configuration, for example, when at least a portion of the person 80 enters a predetermined area after the vertical distance from the lower end of the elevator shaft equipment 13, 18a to the person 80 located below the elevator shaft equipment 13, 18a becomes equal to or less than the second predetermined distance, or when at least a portion of the person 80 continues to enter the predetermined area even after the car deceleration start state is reached and deceleration of the car has begun, the sound output devices 46, 47 can output a warning sound or, as in the above embodiment, can output a message or the like informing the person 80 that they are approaching overhead elevator shaft equipment. Therefore, the safety of the person 80 can be fully ensured. In this case, the second predetermined distance may be less than the predetermined distance, as in the above embodiment, or may be the same as the predetermined distance.

[0083] Furthermore, the control panel 19 can determine, based on the physical quantities detected by the detection devices 35, 39, that the vertical distance from the lower end of the elevator shaft equipment 13, 18a to the downward side is longer than a predetermined distance and is equal to or shorter than a third predetermined distance, and is equipped with sound output devices 46, 47, and when the control panel 19 determines that at least a part of a person has entered a second predetermined area including an area that vertically overlaps with the elevator shaft equipment 13, 18a within a vertical range where the vertical distance is longer than the predetermined distance and is equal to or shorter than the third predetermined distance, the control panel 19 may cause the sound output devices 46, 47 to output a message urging people to be careful of the elevator shaft equipment 13, 18a above.

[0084] This configuration can further improve the safety of the person 80. In addition, frequent execution of car deceleration control can be suppressed, and the efficiency of maintenance and inspection work can be improved.

[0085] Furthermore, the sound output devices 46 and 47 may be configured integrally with the detection devices 35 and 19 .

[0086] According to this configuration, the sound output devices 46, 47 can be installed at the same time as the detection devices 35, 39. This improves convenience and ease of use. Furthermore, since the sound output devices 46, 47 are disposed near the detection devices 35, 39, a sound can be output to alert the person 80 from near the elevator shaft equipment 13, 18a, which is the object that needs to be alerted to the proximity of the person 80. This allows the alert sound, etc. to be effectively and reliably conveyed to the person 80, thereby significantly improving the safety of the person 80.

[0087] The present disclosure is not limited to the above-described embodiment and its modifications, and various improvements and modifications are possible within the scope of the claims of the present application and their equivalents.

[0088] For example, in the above embodiment, the detection devices 35, 39 are described as being integrated with the wireless communication devices 51, 52 and the sound output devices 46, 47. However, the elevator of the present disclosure does not need to have a sound output device that outputs a sound to alert people to the proximity of elevator shaft equipment, and the detection devices may be integrated with only the wireless communication devices. Alternatively, the elevator of the present disclosure does not need to have a sound output device that outputs a sound to alert people to the proximity of elevator shaft equipment, and the detection devices may transmit signals to the control unit of the control device via a wireless communication device configured separately from the detection devices and a wireless communication device of the control device (control panel).

[0089] Alternatively, the elevator of the present disclosure may transmit information from the detection device to a control device (control panel) via a cable. FIG. 10 is a schematic diagram of a modified elevator 110 corresponding to FIG. 1 , FIG. 11 is a schematic diagram of the elevator 110 corresponding to FIG. 7 , and FIG. 12 is a schematic diagram of the elevator 110 corresponding to FIG. 8 . As shown in FIGS. 10 and 11 , the first detection device 135 may be fixed to the counterweight 13, while the wireless communication device and the sound output device may not be fixed to the counterweight 13. For example, while the car 11 is ascending in the direction of arrow A during maintenance, if at least a portion of a person 80 enters a first region including an area overlapping the counterweight 13 in the height direction and the height distance between the counterweight 13 and the person 80 approaches a predetermined distance, the first detection device 135 may detect that at least a portion of the person 80 has entered the predetermined distance. A signal from the first detection device 135 may be transmitted to a control unit of the control panel 119 via a cable 175. The control panel 119 may then determine, based on the transmitted signal, that at least a portion of the person 80 has entered a predetermined area below the counterweight 13 .

[0090] Similarly, as shown in Figures 10 and 12, the second detection device 139 may be fixed to the guide board 18a, while the wireless communication device and the sound output device may not be fixed to the guide board 18a. For example, while the car 11 is ascending in the direction of arrow A during maintenance, if at least a portion of the person 80 enters a second area including an area overlapping the guide board 18a in the vertical direction and the vertical distance between the guide board 18a and the person 80 approaches a predetermined distance, the second detection device 139 may detect that at least a portion of the person 80 has entered the predetermined distance. A signal from the second detection device 139 may be transmitted to a control unit of the control panel 119 via a cable 185. The control panel 119 may determine, based on the transmitted signal, that at least a portion of the person 80 has entered the predetermined area below the guide board 18a.

[0091] When the control panel 119 receives signals from the detectors 135 and 139 via wires, the detectors 135 and 139 may change the strength of the current sent from the detectors 135 and 139 to the control panel 119 to transmit information from the detectors 135 and 139 to the control panel 119. The control panel 119 may also activate the brake by changing the amount of current supplied to the coil of the hoist motor 12a in accordance with the change in the current sent from the detectors 135 and 139.

[0092] In addition, when at least a part of the person 80 enters a specified area, the detection devices 135, 139 may change the amount of transmission current sent to the control panel 119 depending on the vertical distance between the elevator shaft equipment 13, 18a and the person 80; for example, the detection devices 135, 139 may send to the control panel 119 a transmission current that increases as the vertical distance decreases, and the control panel 119 may perform control such that the deceleration acceleration of the car 11 when decelerating increases as the received transmission current increases.

[0093] Alternatively, when at least a portion of the person 80 enters a specified area, the detection devices 135, 139 may send to the control panel 119 a transmission current that decreases as the vertical distance decreases, and the control panel 119 may perform control such that the deceleration acceleration of the cage 11 increases as the received transmission current decreases.

[0094] Furthermore, when the first detection device 135 is fixed to the balance weight 13 while the wireless communication device and sound output device are not fixed to the balance weight 13, and when the detection device 139 is fixed to the guide plate 18a while the wireless communication device and sound output device are not fixed to the guide plate 18a, the control panel 119 may perform an example of control to increase the safety of the person 80 based on information from the first detection device 135, which will be described next.

[0095] In this case, the control panel 119 can perform the same control as that described below based on information from the second detection device 139, but the description of this control will be omitted with the description of the control that will be described next. Also, while the control described below is being performed using the first detection device 135 and all of the second detection devices 139, if a deceleration operation of the car 11 is performed based on the detection result of any one of the detection devices 135, 139, the control based on the detection result of the detection devices 135, 139 other than that one may be terminated, and the control of the detection devices 135, 139 other than that one may be started from step S11 after the deceleration operation has ended.

[0096] 13 is an example of a flowchart illustrating an example of control performed by the control panel 119 of the elevator 110 to increase the safety of the person 80 by making it difficult for the person 80 to approach the counterweight 13. For example, the control starts when the mode of the elevator 110 is changed from a normal mode in which the raising and lowering of the car 11 is controlled based on the destination floor designation button 16, which is used by a person inside the car 11 to designate a destination floor for the car 11, to a maintenance and inspection mode in which the car 11 does not move based on the destination floor designation button 16, by operating a mode selection unit provided on the back side of the destination floor designation button 16 or the like.

[0097] In step S11 after the start of control, the control panel 119 determines, based on information from the first detection device 135, whether at least a part of the person 80 has entered a specified area below the counterweight 13, for example, whether at least a part of the person 80 has entered a specified area that is a vertical distance from the lower end of the counterweight 13 downward that is less than a specified distance and that includes an area that overlaps the counterweight 13 vertically.

[0098] If a negative determination is made in step S11, the control returns and step S11 is performed again. On the other hand, if a positive determination is made in step S11, the control proceeds to step S12, where the control panel 119 controls the hoist motor 12a to start the stopping operation of the car 11, and then the control proceeds to step S13.

[0099] In step S13, the control panel 119 determines whether all of the people 80 have left the predetermined area based on information from the first detection device 135. If a positive determination is made in step S13, the process proceeds to step S14, where the deceleration control of the car 11 is terminated and the speed of the car 11 is returned to the speed before deceleration. Then, control returns and step S11 and subsequent steps are performed again. As is clear from the procedure in step S14, with this control, even if the deceleration control of the car 11 is performed, it is possible that the car 11 will not stop. On the other hand, if a negative determination is made in step S13, the process proceeds to step S15, where the control panel 119 determines whether the car 11 has stopped based on information from an encoder (not shown, for example, the above-mentioned absolute type encoder), etc.

[0100] If a negative determination is made in step S15, the process proceeds to step S16, where the control panel 119 controls the hoist motor 12a to continue the stopping operation of the car 11, and then steps S13 and onward are performed. On the other hand, if a positive determination is made in step S15, the process proceeds to step S17, where the speed of the car 11 is returned to the speed before deceleration, and then the control returns, and steps S11 and onward are performed again.

[0101] This control ends when the mode of the elevator 10 is changed by operating the mode selection unit from a maintenance and inspection mode in which the car 11 does not move based on the destination floor designation button 16 to a normal mode in which the raising and lowering of the car 11 is controlled based on the destination floor designation button 16, which allows a person inside the car 11 to designate the destination floor of the car 11.

[0102] It should be noted that, when the elevator of the present disclosure has one or more sound output devices that output a sound to person 80 related to the proximity of hoistway equipment, the sound output device does not have to be integrated into the detection device. When the elevator of the present disclosure has multiple sound output devices that output a sound to person 80 related to the proximity of hoistway equipment, the multiple sound output devices may be arranged at predetermined intervals in the height direction in the hoistway, may be arranged at equal intervals in the height direction in the hoistway, or may be arranged at unequal intervals in the height direction in the hoistway.

[0103] In addition, the case where the predetermined area is an area in which the height direction distance from the lower end of the elevator shaft equipment 13, 18a to the lower side is equal to or less than the predetermined distance and includes an area that overlaps with (all of) the elevator shaft equipment 13, 18a in the height direction has been described. However, the predetermined area may be any area that is below the elevator shaft equipment, and may be, for example, an area in which the height direction distance from the lower end of the elevator shaft equipment to the lower side is equal to or less than the predetermined distance and that overlaps with only a portion of the elevator shaft equipment in the height direction.

[0104] Also, in the above description, the multiple elevator shaft pieces of equipment to which the detection devices are attached include the counterweight 13 and the multiple guide plates 18a. However, the multiple elevator shaft pieces of equipment to which the detection devices are attached may include only the counterweight or only the multiple guide plates 18a. Alternatively, the one or more elevator shaft pieces of equipment to which the detection devices are attached may include pieces of equipment other than the counterweight and the guide plates, such as a tie bar or the like provided on the guide rail on the counterweight side to prevent objects from entering and interfering with the wire rope.

[0105] In addition, in the above description, when the plurality of elevator shaft equipment to which the detection device is to be attached includes a counterweight 13, the detection device 35 is attached to the spacer 13c of the counterweight 13. However, when the plurality of elevator shaft equipment to which the detection device is to be attached includes a counterweight, the detection device may be attached to a location other than the spacer of the counterweight.

[0106] Also, the case where the detection devices 35, 39 are detachable from the elevator shaft equipment 13, 18a has been described, and the case where the deceleration control of the car 11 of the present disclosure is performed only in the maintenance mode has been described. However, the detection devices may be permanently fixed to the elevator shaft equipment, and the control device may determine whether the car is in a deceleration start state when the car is in a normal mode in which the car moves based on a destination floor designation button provided in the car.
