Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boarding and alighting guidance device for indicating whether or not a passenger can board a car in an elevator.

Generally, elevators are provided with safety means including overload detection means (Patent Document 1). For example, if the overload detection means detects that the car is overloaded (110% or more of the rated load) when a passenger is boarding the car, the safety means will issue an alarm such as a buzzer and open the car door. Maintain the condition and do not close the door. Thereby, the safety means prevents the overloaded car from starting to run, and prevents the rope from breaking due to the run of the overloaded car.

By the way, when a safety measure issues a warning such as a buzzer regarding an overloaded car, the passenger who triggered the warning may feel embarrassed. In addition, the above-mentioned safety measures issue a warning after a passenger who causes overloading has boarded the car, and then the passenger exits the car after the warning, so there is a problem that operation efficiency is reduced due to unnecessary boarding and alighting. On the other hand, even if the cars are fully loaded with sufficient loading capacity to avoid unnecessary boarding and alighting, a decline in operational efficiency is unavoidable as passengers wait longer for their cars at the landing. . In order to suppress such a decrease in operating efficiency, the ratio of the load to the rated load is displayed inside the car (Patent Document 2), and the remaining load capacity of the car is displayed inside the car or at the landing (Patent Document 2). Reference 3).

Japanese Patent Application Publication No. 2005-281003 Utility Model Publication No. 59-11866 Utility Model Publication No. 63-142368

However, the above-mentioned display is not sufficient to guide passengers to decide whether or not to board the vehicle, nor is it sufficient to improve operational efficiency.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator boarding/exiting guidance device that improves operating efficiency by allowing passengers to accurately determine whether or not they are permitted to board the car.

The elevator boarding and alighting guide device of the present invention includes:
Equipped with a display that is placed in a position that is visible to passengers staying at the landing and that can display information regarding the loading capacity of the car,
The display device is
When the carrying load of the car is less than or equal to a second threshold value, which is smaller by a first predetermined mass than the first threshold value at which the car cannot be boarded due to overloading, a first display informing that the car can be boarded. Take the state;
When the carrying load of the car is larger than the second threshold value and smaller than the first threshold value, a second display state is set to indicate that the car should not be boarded;
The first predetermined mass is a mass that allows one or two passengers to board the car.

According to this configuration, a passenger who wants to get into the car can determine based on the first display state that he or she can get on the car, and can determine that he or she should not get on the car based on the second display state.

Further, in the boarding and alighting guide device,
The indicator may take a third display state for guiding the user to get off the car when the load of the car is equal to or higher than a first threshold value.

According to this configuration, a passenger who is about to get into the car can determine that it is necessary to get out of the car based on the third display state.

Further, the boarding and alighting guide device includes:
The display device is configured such that the detection result by a load detector that detects the car load increases when the car load is larger than the second threshold value and smaller than the first threshold value, and The third display state may be taken even when the value is smaller than .

According to this configuration, when a passenger gets into the car in the second display state, by switching to the third display state, the passenger who gets into the car is unable to get into the car in the second display state. You can make them learn things.

Further, in the boarding and alighting guide device,
The display device is
When the carrying load of the car is 0, a fourth display state indicating that the car is unmanned is taken;
When the carrying load of the car is greater than 0 and less than about half of the second threshold, a fifth display state is set to indicate that there is a margin to a state where the car should not be boarded;
When the carrying load of the car is more than about half of the second threshold and less than or equal to the second threshold, a sixth display state may be taken to indicate that the car is approaching a state in which the car should not be ridden. .

According to this configuration, by the time the car load reaches the second threshold value, the sixth display state indicating that the car is approaching a state where the car should not be boarded is taken, so that the car is not recommended to board the car. It is possible to notify passengers in advance that a situation is approaching.

Further, in the boarding and alighting guide device,
The display device is
When there is no car call in a state where the carrying load of the car is greater than 0 and less than the second predetermined mass, the fourth display state is taken;
When a car call is made while the car's live load is greater than 0 and less than the second predetermined mass, and when the car's live load is greater than or equal to the second predetermined mass and less than approximately half of the second threshold value. , take the fifth display state,
The second predetermined mass may be 20 kg or more and 50 kg or less.

According to this configuration, when no one is riding in the car and the load detector makes an erroneous detection, the fifth display state can be prevented.

Further, the boarding and alighting guide device includes:
A boarding detector is provided on the open side of the car door and detects a passenger boarding the car in a non-contact manner,
The display device is
When the occupancy detector detects a passenger boarding in a state where the car load is greater than or equal to a third threshold value and smaller than the second threshold value, the second display state is assumed;
the third threshold is smaller than the second threshold by a third predetermined mass;
The third predetermined mass may be greater than or equal to 30 kg and less than or equal to 85 kg.

According to this configuration, when a passenger gets into the car in a state where it is impossible for one passenger to board the car in a state where the car should not be boarded, for example, the first passenger is not allowed to board the car without waiting for the detection result of the load cell. By having two display states, the status can be communicated to passengers more quickly and operational efficiency can be improved.

Further, in the boarding and alighting guide device,
The display may be at least one of a car display provided on the car and a hall display provided on the landing.

According to this configuration, it can be determined whether a passenger can board the car based on the display on the car display or the hall display.

As described above, according to the present invention, it is possible to provide an elevator boarding/exiting guidance device that improves operating efficiency by allowing passengers to accurately judge whether or not they are allowed to board the car.

The display state is shown, and (c) shows the third display state.

A first embodiment of the present invention will be described below. The boarding and alighting guide device according to the present embodiment is provided in an elevator that includes a hoistway that extends vertically across a plurality of floors within a building, and a car that moves up and down the hoistway. This elevator has one car. In this embodiment, the car is a small car with a capacity of 15 people or less (for example, a capacity of 15 people). Note that this car may be a large car with a capacity of 16 or more people.

As shown in FIG. 1, the boarding and alighting guide device 1 includes a display 4 that is placed in a position that is visible to passengers staying at the landing 3 and is capable of displaying information regarding the loading capacity of the car 2.

The elevator has a load detector 5 that detects the live load of the car 2. The load detector 5 is, for example, a load cell that detects the mass of the car 2. This load cell is placed under the floor of the car 2.

The display device 4 of this embodiment includes three display sections 41, 42, and 43. Note that the display device 4 may be composed of one display section, or may be composed of two display sections or a plurality of display sections of four or more. The display units 41, 42, and 43 are, for example, lamps such as LED lamps, and always emit light of the same color when turned on. It emits light (light bulb color).

Note that at least two of the plurality of display sections forming the display device 4 may emit light of different colors. Furthermore, each display section may switch and emit light of different colors. Each display section may switch and emit light of a different color by completely changing the color, or may switch to and emit light of a different color by changing the color with gradation.

The indicator 4 is, for example, a car indicator provided in the car 2. The car indicator is provided at a location near the entrance/exit 20 of the car 2, for example, at the transom 21. The transom 21 is a curtain plate disposed above the entrance 20 of the car 2 (on the opposite side from the car sill). Specifically, the display sections 41, 42, and 43 are arranged in the central region in the horizontal direction of the surface of the transom 21 facing the landing 3, and are arranged at equal intervals from each other in the horizontal direction.

Note that the car indicator may be provided at the bottom (lower surface) or corner of the transom 21, or may be provided at a location other than the transom 21. The car display device is, for example, a wing wall located on both sides below the transom 21 (a wing wall arranged on both sides of the entrance/exit 20 of the car 2), a safety shoe provided on the car door, or a safety shoe on the door opening side of the car door. It may be provided on at least one of the end portion, the car floor, the car sill, etc. When a car indicator is used as the indicator 4, it is not necessary to provide the indicator 4 on each floor, so the installation cost of the indicator 4 can be suppressed.

As shown in FIG. 2, the display 4 assumes a first display state that indicates that the car 2 can be boarded when the load of the car 2 is less than or equal to the second threshold value. Furthermore, when the load of the car 2 is larger than the second threshold value and smaller than the first threshold value, the display device 4 assumes a second display state that indicates that the car 2 should not be boarded. In the present embodiment, the display 4 assumes a third display state in which the driver is guided to get off the car 2 when the load of the car 2 is equal to or greater than the first threshold value. Furthermore, when the load of the car 2 is 0, the display 4 assumes a fourth display state indicating that the car 2 is unmanned. In FIG. 2, the upper row shows the load of the car 2, and the lower row shows the display state of the display 4.

The first threshold value is the mass at which it becomes impossible to board the car 2 due to overloading. Specifically, the first threshold value can be set to 110% of the rated loading capacity of the car 2 (a value obtained by multiplying the capacity of the car 2 by the weight per passenger (for example, 75 kg)).

The second threshold value is smaller by the first predetermined mass than the first threshold value at which entry into the car 2 is prohibited due to overloading. The first predetermined mass is a mass that allows one or two passengers to board the car 2. That is, the first predetermined mass may be set to a mass that allows one passenger to board the car 2, or may be set to a mass that allows two passengers to board the car 2. good. Specifically, the first predetermined mass is the mass (for example, 105 kg). The maximum weight per passenger is determined from the fact that more than 99% of Japanese adult males weigh 98 kg or less. Note that the first predetermined mass can be set to a value other than 105 kg (for example, any value within the range of 70 kg to 200 kg) in countries and regions other than Japan.

In the present embodiment, the display device 4 takes a first display state when there is enough room to reach a state in which the car should not be boarded, and a fifth display state to guide the user. When there is, it takes a sixth display state to guide you. Specifically, when the carrying load of the car 2 is greater than 0 and less than about half of the second threshold value, the display 4 displays a fifth display state that indicates that there is a margin to a state in which the car should not be boarded. I take the. In addition, when the load of the car 2 is greater than about half of the second threshold and less than or equal to the second threshold, the display 4 displays a sixth display that indicates that the car is approaching a state in which the car should not be boarded. Take the state. Note that approximately half of the second threshold value is, for example, 45% or more and 55% or less of the second threshold value.

Each display state that the display 4 can take will be described below with reference to FIGS. 3(a) to 3(e). In the present embodiment, the display device 4 indicates each display state by changing the states of the display sections 41, 42, and 43 such as off, on, and blinking. In this display device 4, the display units 41, 42, and 43 change the fourth, fifth, sixth, and second display states by changing the number of lit display units and the number of unlit display units. It is shown by letting Specifically, the fourth display state is a state in which all of the display sections 41, 42, and 43 are turned off, as shown in FIG. 3(a). In the fifth display state, as shown in FIG. 3(b), the leftmost display part 41 among the display parts 41, 42, and 43 is lit, and the remaining display parts 42 and 43 are turned off. . In the sixth display state, as shown in FIG. 3(c), among the display sections 41, 42, and 43, the leftmost display section 41 and the center display section 42 are lit, and the remaining display sections are turned on. 43 is in a state where the light is off. The second display state is a state in which all of the display sections 41, 42, and 43 are lit, as shown in FIG. 3(d). The third display state is a state in which all of the display sections 41, 42, and 43 are blinking, as shown in FIG. 3(e).

Note that the display device 4 may indicate each display state by a change in the blinking pattern of the display sections 41, 42, and 43 (for example, a change in the time taken for one blink) or a change in the lighting color. In this case, the display parts 41, 42, and 43 may change so that the lighting color increases the warning feeling as the load of the car 2 increases. For example, the display units 41, 42, and 43 can light up in blue in the fifth display state, flash in blue in the sixth display state, flash in yellow in the second display state, and flash in red in the third display state. Note that when the display units 41, 42, and 43 indicate each display state by a change in blinking pattern or a change in lighting color, the display unit 4 may be configured with one display unit (LED lamp).

In this embodiment, the display 4 assumes each display state when the car 2 is stopped and just before stopping at a stop floor. Thereby, the display device 4 can inform passengers who are about to board the car 2 of the status of the car 2. Note that the display 4 may take various display states when the car 2 is running, in addition to when the car 2 is stopped and just before stopping at a stop floor.

According to the above boarding/exiting guide device 1, when the carrying load of the car 2 is less than or equal to the second threshold value (a value smaller than the first threshold value at which it is impossible to board the car 2 by the first predetermined mass), When a passenger who wants to board car 2 determines that he or she can board car 2 based on the first display state that indicates that he or she can board car 2, and the carrying load of car 2 is greater than the second threshold, It can be determined that this passenger should not board the car 2 based on the second display state that indicates that the passenger should not board the car 2. Therefore, according to this boarding and alighting guidance device 1, compared to a configuration that does not provide "guidance that the car 2 should not be boarded", the car 2 is in a state where the boarding load is not to be boarded (a state where the live load is at the second threshold value). Since it is difficult for the passenger to board the car 2, it is unlikely that the passenger will be forced to get off the car from the car 2. Moreover, according to this boarding/disembarking guidance device 1, compared to a configuration that does not provide "information that the car 2 can be boarded", boarding to the car 2 that is available for boarding is promoted, and the boarding to the car 2 that is available for boarding is promoted. It is less likely that passengers will be forced to abandon their rides. Therefore, operation efficiency can be improved.

According to the boarding and alighting guide device 1 of the present embodiment, when the load of the car 2 becomes equal to or higher than the first threshold value (in this embodiment, 110% or more of the rated load capacity), a passenger who attempts to board the car 2 , it can be determined that it is necessary to get off the car 2 based on the third display state that guides the user to get off the car 2.

Furthermore, according to the boarding and alighting guide device 1 of the present embodiment, by taking the sixth display state in which the car is approaching a state in which the car should not be boarded, by the time the carrying load of the car 2 reaches the second threshold value, It is possible to notify passengers in advance that they are approaching a state where they should not board the car 2.

It should be noted that the boarding and alighting guide device of the present invention is not limited to the above-described embodiments, and it goes without saying that various changes may be made without departing from the gist of the present invention. For example, the configuration of another embodiment can be added to the configuration of one embodiment, and a part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Additionally, some of the configurations of certain embodiments may be deleted.

Further, in the above embodiment, the display device 4 was in the first display state (the fifth display state and the sixth display state), the second display state, the third display state, and the fourth display state; It is sufficient to take at least the first display state and the second display state, and it is not necessary to take at least one of the third display state and the fourth display state. For example, when the load of the car 2 is equal to or higher than the first threshold, instead of the display 4 taking the third display state that guides the user to get off the car 2, the speaker installed in the car 2 or the landing 3 A buzzer sound, voice announcement, or the like may be output to guide the user to get off the car 2. Further, in addition to when the live load of car 2 is greater than the second threshold and smaller than the first threshold, the indicator 4 indicates that the car 2 is not loaded. A second display state may be adopted that provides guidance on what not to do.

Each possible display state of the display 4 according to the above embodiment and other embodiments will be described below with reference to FIGS. 4 to 7(c).

In the embodiments described above, the second display state indicates that the passenger should not board the car 2, but it is preferable that the passengers who have boarded the car 2 learn this fact. In this embodiment, as shown in FIG. 4, the indicator 4 displays the first threshold value when the live load of the car 2 is greater than the second threshold value, as well as when the live load of the car 2 is greater than the second threshold value. Even if the detection result by the load detector 5 increases in a state where the load is smaller than the first threshold, and the load of the car 2 is smaller than the first threshold, a third display state for guiding the user to get off the car 2 is displayed. take. According to this configuration, when a passenger gets into car 2 in the second display state that indicates that the passenger should not board car 2, even if the passenger is smaller than the first threshold, the passenger is not allowed to get off from car 2. The display switches to the third display state that guides you. This allows the passengers who have boarded the car 2 to learn that they cannot board the car 2 in the second display state.

Further, the load cell serving as the load detector 5 may incorrectly detect that the load of the car 2 is greater than 0 even though the car 2 is unmanned. On the other hand, the display 4 may take various display states shown in FIG. 5 depending on the load of the car 2 and the presence or absence of a car call. In the present embodiment, the display 4 displays a fourth display state that indicates that the car 2 is unmanned when the car 2 has a load greater than 0 and less than the second predetermined mass and there is no car call. When a car call is made while the live load of the car is greater than 0 and less than the second predetermined mass, and when the live load of the car 2 is greater than or equal to the second predetermined mass and less than approximately half of the second threshold value. At some point, a fifth display state is assumed, which indicates that there is still enough time to reach a state in which the car should not be boarded. The second predetermined mass is a value that is estimated to be a false detection of the load cell (a value that cannot be considered as a detection result by a passenger), and is a value that is larger than 0 kg and smaller than the weight of each passenger (for example, 75 kg). . For example, the second predetermined mass is 20 kg or more and 50 kg or less. Note that the car call is performed when a passenger who has boarded the car 2 operates a car operating device (for example, presses a destination floor button in the car 2). According to this configuration, when the load detector 5 makes an erroneous detection when no one is riding in the car 2, the state indicating that a passenger is riding in the car 2 (fifth display state) and can be prevented from happening.

By the way, the load cell serving as the load detector 5 accurately detects the carrying load of the car 2 by waiting until the detected value becomes stable after a passenger gets into the car 2. Specifically, it takes about 1 to 3 seconds for the load cell to accurately detect the load of the car 2. On the other hand, the boarding and alighting guide device 1 is provided with a boarding detector that is provided on the open side of the car door and detects a passenger boarding the car 2 in a non-contact manner, and this boarding detector quickly detects boarding. You may. This occupancy detector is, for example, a multi-beam sensor including a light emitting element and a light receiving element. The light emitting element of the multi-beam sensor emits a plurality of detection beams extending in parallel lines in the opening/closing direction of the car door toward the light receiving element. Note that the occupancy detector may be an infrared sensor or an image sensor that captures images of passengers in the car 2.

In this embodiment, as shown in FIG. 6, the display 4 indicates that when the boarding detector detects a passenger boarding while the load of the car 2 is greater than or equal to the third threshold and smaller than the second threshold. , a second display state is assumed, which indicates that the car 2 should not be boarded. The third threshold value is a value that allows a maximum of two passengers to board the car 2 before the live load of the car 2 reaches the first threshold value. Specifically, the third threshold value is smaller than the second threshold value by a third predetermined mass, and the third predetermined mass is, for example, 30 kg or more and 85 kg or less. In addition, in this display 4, when the rider detector reacts, it is determined that the reaction is due to boarding when the detection result of the load cell is increasing, and it is determined that the reaction is due to getting off the vehicle when the detection result of the load cell is decreasing. It is determined that According to this configuration, when a passenger gets into the car 2 in a state where the car 2 is close to a state where it is impossible for one passenger to get into the car 2, the load detector 5 (load cell) detects the situation. By taking the second display state to inform passengers that they should not board car 2 without waiting for the result, it is possible to more quickly inform passengers of the status and improve operational efficiency.

In addition, in this embodiment, the third predetermined mass is 75 kg and the first predetermined mass is 105 kg, so the third threshold value is 180 kg smaller than the first threshold value. Furthermore, more than 95% of two Japanese adult males have a total weight of 180 kg or less. Therefore, when the boarding detector detects a passenger boarding in a state where the load of the car 2 is equal to or higher than the third threshold value and smaller than the second threshold value, the display device 4 indicates that there is no passenger in the car 2 after this boarding. Furthermore, even if one person gets in the car, it is unlikely that the load of the car 2 will exceed the first threshold value. Therefore, the display 4 indicates that the passenger should not board the car 2 when the occupancy detector detects a passenger boarding in a state where the live load of the car 2 is greater than or equal to the third threshold value and smaller than the second threshold value. It is sufficient to take the second display state for guidance.

Further, in this embodiment, the boarding detector detects a passenger boarding when the load of car 2 is equal to or higher than the third threshold value and smaller than the second threshold value, and provides guidance that the passenger should not board car 2. After taking the second display state, when the detection result of the load cell becomes stable and this detection result (loading load of car 2 detected by the load cell) is smaller than the second threshold, the display 4 displays the sixth display. The display state may be returned to the original state, or the second display state may be maintained.

In the above embodiment, the display device 4 was composed of a lamp, but it may be composed of a display panel such as a liquid crystal display. In this case, the display 4 displays text that guides the status of the car 2 (for example, text such as "You can board the car," text such as "You cannot board the car," text such as "Please get off the car," etc.) Each display state may be indicated by switching the display. Further, the display device 4 may include a scale plate that displays a scale, and a needle that indicates the scale in accordance with the load of the car 2.

In the above embodiment, the display device 4 is a car display device, but it may be a hall display device provided in a hall. In this embodiment, for example, as shown in FIGS. 7(a) to 7(c), the hall display may include both a hall lantern 30 and a hall call button 31. According to this configuration, it can be determined from the display on the hall display whether a passenger can board the car 2 or not. When a hall display is used as the display 4, passengers can easily check each display state even from a position away from the car 2 in the hall 3. In this embodiment, both the hall lantern 30 and the hall call button 31 emit blue light in the first display state shown in FIG. 7(a), and emit yellow light in the second display state shown in FIG. 7(b). However, in the third display state shown in FIG. 7(c), red light is emitted.

Furthermore, in this embodiment, the display on the display 4 is maintained at least until the car door is completely closed after the car 2 stops at the landing and after the user gets off and gets on the car. Thereby, a passenger who wants to board the car 2 can check each display state while performing the boarding operation. In this embodiment, while the car 2 is running, the hall lantern 30 and the hall call button 31 both emit bulb-colored or white light, from when the car door opens when the car 2 arrives until the door closes. During this period, light corresponding to each display state is emitted.

Note that the hall display may include at least one of the hall lantern 30 and the hall call button 31. In FIGS. 7(a) to 7(c), the hall lantern 30 is placed above the hall call button 31, but it may be placed at another location. The buttons 31 may be arranged side by side in the horizontal direction. Further, the hall display device may be, for example, an LED lamp or a display panel provided on a vertical frame of a three-sided frame. Furthermore, the display 4 may be composed of both a car display and a hall display.
