DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In each drawing, the same or corresponding parts are designated by the same reference numerals, and the description thereof will be simplified or omitted.

[0012] FIG. 1 is a cross-sectional schematic diagram showing the overall configuration of an elevator and its surroundings according to the first embodiment. FIG. 1 shows a schematic longitudinal cross section of an elevator hoistway. As shown in FIG. 1, an elevator 100 has a car 1 that moves up and down in a hoistway 10. An over-car rail 2 is installed outside and above the car 1. The over-car rail 2 is a mounting section for loading a luggage cart 5 onto the car 1. The luggage cart 5 is configured to be guided by the over-car rail 2 and be loaded onto the car 1.

[0013] The elevator 100 in the first embodiment is equipped with a door device. In this embodiment, the door device is configured to be able to open and close the car door and the hall door not only when the car 1 is parked at an appropriate landing position, but also when the car 1 is parked at a predetermined boarding / alighting position. Here, the appropriate landing position is a position where the heights of the floor surface of the car 1 and the floor surface 6a of the hall 6 are roughly the same, and is a position where passengers can board and alight in the car 1. In addition, the boarding / alighting position is a position where the heights of the floor surface 6a of the hall 6 and the car overhead rail 2 are the same, allowing boarding and alighting of the baggage cart 5.

[0014] The configuration of the door device will be described in detail below. The door device is composed of a car door device 3 and a landing door device 4. As shown in FIG. 1, the car door device 3 is installed on the car 1. The car door device 3 is composed of a car door drive device 3a, a car door 3b, a car door threshold 3c, and an actuator (not shown) that drives the car door drive device 3a. Here, the car door 3b is a pair of door panels arranged on the left and right at the entrance to the car 1. The car door device 3 drives the car door drive device 3a with an actuator to move the car door 3b left and right, thereby opening and closing the entrance to the car 1.

[0015] The landing door device 4 is installed at the landing 6 of each floor where the elevator 100 stops. The landing door device 4 includes an upper landing door opening / closing device 4a, a landing door 4b, a landing door threshold 4c, and a lower landing door opening / closing device 4d. The landing doors 4b are a pair of door panels arranged on the left and right at the entrance and exit of the landing 6. The upper landing door opening / closing device 4a is connected to the car door drive device 3a when the car 1 is in the landing position, and causes the car door drive device 3a to open and close the landing door 4b. The lower landing door opening / closing device 4d is connected to the car door drive device 3a when the car 1 is in the boarding / alighting position, and causes the car door drive device 3a to open and close the landing door 4b. In the following description, directions such as left and right and clockwise refer to left and right directions on the plane of each drawing.

[0016] Fig. 2 is a schematic diagram showing the configuration of the landing door device according to this embodiment. A detailed configuration of the landing door device 4 according to this embodiment will be described with reference to Fig. 2. As shown in Fig. 2, the upper landing door opening and closing device 4a includes an upper housing 4a1, a right opening and closing plate 4a2, a left opening and closing plate 4a3, left and right interlocking ropes 4a4, left and right interlocking rope pulleys 4a5, a right rope fixing member 4a6, a left rope fixing member 4a7, and an upper engagement rod 4a8.

[0017] The upper housing 4a1 is disposed above the landing door 4b. A pair of left-right interlocking rope pulleys 4a5 are disposed on the left and right sides of the upper housing 4a1. A looped left-right interlocking rope 4a4 is wound around the left-right interlocking rope pulleys 4a5 under tension.

[0018] The left opening / closing plate 4a3 and the right opening / closing plate 4a2 are guided on rails or the like and move left and right relative to the upper housing 4a1. The left opening / closing plate 4a3 and the right opening / closing plate 4a2 are connected to the left and right landing doors 4b, respectively, and open and close the landing doors 4b by their movement. The right opening / closing plate 4a2 is fixed to the left and right interlocking ropes 4a4 by a right rope fixing 4a6, and the left opening / closing plate 4a3 is fixed to the left and right interlocking ropes 4a4 by a left rope fixing 4a7.

[0019] The upper engagement rod 4a8 is fixed to the left opening / closing plate 4a3. The upper engagement rod 4a8 is arranged so as to be located at an engagement position where it engages with an engagement plate installed in the car door drive device 3a when the car 1 is at the landing position. A first coupling portion is formed by the upper engagement rod 4a8, which is the upper engagement portion, and the engagement plate of the car door drive device 3a, which is the car-side engagement portion. When the car 1 is parked at the landing position, the upper engagement rod 4a8 engages with the engagement plate, thereby coupling the car door drive device 3a and the upper landing door opening / closing device 4a and unlocking the landing door 4b.

[0020] In a state in which the car door drive device 3a and the upper landing door opening / closing device 4a are coupled, the upper engagement rod 4a8 is pushed by the car door drive device 3a and moves left and right together with the left opening / closing plate 4a3. For example, when opening the entrance to the landing 6, the left opening / closing plate 4a3 moves leftward. The left and right interlocking rope 4a4 fixed to the left opening / closing plate 4a3 by the left rope fixation 4a7 rotates counterclockwise. At this time, the right opening / closing plate 4a2 fixed to the left and right interlocking rope 4a4 by the right rope fixation 4a6 moves rightward. This allows the landing door 4b to be opened left and right. The closing movement of the landing door 4b is the reverse of this movement.

[0021] The lower landing door opening / closing device 4d includes a lower housing 4d1, a lower opening / closing plate 4d2, an upper / lower interlocking rope 4d4, an upper / lower interlocking rope pulley 4d5, an upper rope fixing member 4d6, a lower rope fixing member 4d7, a lower engagement rod 4d8, a lock / release interlocking rope 4d9, three lock / release interlocking rope pulleys 4d10, and a lock / release hook 4d11. The lock / release interlocking rope 4d9 is wound around the three lock / release interlocking rope pulleys 4d10. One end of the lock / release interlocking rope 4d9 is fixed to the lock / release hook 4d11, and the other end is fixed to the lower engagement rod 4d8.

[0022] The lower engagement part, that is, the lower engagement rod 4d8, the lock / release interlock rope 4d9, the three lock / release interlock rope pulleys 4d10, the lock / release hook 4d11, and the upper engagement rod 4a8, together with an engagement plate (not shown) installed in the car door drive device 3a, constitute a second connection part in the present disclosure. In addition, the lock / release interlock rope 4d9, the three lock / release interlock rope pulleys 4d10, and the lock / release hook 4d11 constitute an engagement interlock part in the present disclosure.

[0023] When the car 1 is parked at a boarding / disembarking position for boarding and disembarking the baggage trolley 5, the lower engagement rod 4d8 engages with the engagement plate, thereby connecting the car door drive device 3a and the upper landing door opening / closing device 4a. When the car door drive device 3a and the lower landing door opening / closing device 4d are engaged, the lower engagement rod 4d8 rotates counterclockwise. This pulls the lock release interlocking rope 4d9, pulling the lock release hook 4d11 to the left along the lock release interlocking rope pulley 4d10. The lock release hook 4d11 is hooked onto the upper part of the upper engagement rod 4a8. When the lock release hook 4d11 moves leftward, the upper engagement rod 4a8 rotates counterclockwise. This releases the lock between the left opening / closing plate 4a3 and the right opening / closing plate 4a2. When the car door drive device 3a and the lower landing door opening / closing device 4d are disengaged, the unlocking hook 4d11 moves rightward due to the spring force of a leaf spring or the like, and the upper engaging rod 4a8 is returned to the locked state.

[0024] The lower opening / closing plate 4d2 is a lower opening / closing unit that is guided by a rail or the like and moves left and right relative to the lower housing 4d1. A vertical interlocking rope 4d4 is looped around four vertical interlocking rope pulleys 4d5 arranged on the left and right sides of the lower housing 4d1 and the upper housing 4a1 under tension. The right opening / closing plate 4a2 is fixed to the vertical interlocking rope 4d4 by an upper rope fixing 4d6, and the lower opening / closing plate 4d2 is fixed to the vertical interlocking rope 4d4 by a lower rope fixing 4d7. The lower engagement rod 4d8 is fixed to the lower opening / closing plate 4d2. The four vertical interlocking rope pulleys 4d5, the vertical interlocking rope 4d4, the upper rope fixing 4d6, and the lower rope fixing 4d7 constitute an opening / closing interlocking unit that transmits the operation of the lower opening / closing plate to operate the upper landing door opening / closing device 4a.

[0025] When the landing door 4b is opened, the lower opening-closing plate 4d2 fixed to the lower engagement rod 4d8 moves leftward as the car door drive device 3a moves. In conjunction with this, the vertical interlocking rope 4d4 fixed by the lower rope fixation 4d7 rotates clockwise. The vertical interlocking rope 4d4 is fixed to the right opening-closing plate 4a2 by the upper rope fixation 4d6. Therefore, the right opening-closing plate 4a2 moves rightward together with the upper rope fixation 4d6. In addition, the left-right interlocking rope 4a4 is fixed to the right opening-closing plate 4a2 by the right rope fixation 4a6. Therefore, movement of the right opening-closing plate 4a2 in the opening direction rotates the left-right interlocking rope 4a4 counterclockwise, and moves the left opening-closing plate 4a3 leftward. This causes the landing door 4b to open to the left and right. The operation in the closing direction of the landing door is the reverse of this operation.

[0026] The upper engagement rod 4a8 is configured to rotate counterclockwise and release the lock when the engagement plate of the car door drive device 3a engages with it. In other words, the upper engagement rod 4a8 also functions as a mechanical locking mechanism, and is configured so that the lock is released and the landing door 4b can be opened only when the car door drive device 3a engages with it. The locking mechanism may also use a method of electrically releasing the lock by providing an actuator.

[0027] In the first embodiment, for example, the hall operating panel is provided with a hall call button for inputting a normal call registration for boarding the car 1, as well as a cart boarding / alighting button for inputting a command for boarding and alighting the baggage cart 5. By pressing the boarding / alighting button, a user can open or close the hall door 4b with the car 1 stopped at the boarding / alighting position. This allows the baggage cart 5 to be loaded onto or removed from the car 1. The command for boarding and alighting the baggage cart 5 is not limited to being input from the hall operating panel, and may be configured to be input from, for example, an external terminal or the like.

[0028] As described above, according to this embodiment, the baggage cart 5 can be stored in the space above the car 1 of the elevator 100 as needed. Therefore, the space occupied by the elevator 100 can be used effectively.

[0029] In this embodiment, the car door 3b and the landing door 4b are described as being double-swing doors. However, the car door and the landing door may be, for example, single-swing doors. Even in this case, by providing an upper landing door device and a lower landing door device above and below the landing door 4b and providing a mechanism that can open and close the landing door 4b by engaging with the car door drive device 3a, it is possible to similarly store the baggage cart 5 in the space above the car 1 of the elevator 100.

[0030] Embodiment 2 3 is a cross-sectional schematic diagram showing the overall configuration of an elevator and its surroundings according to embodiment 2. Elevator 200 of embodiment 2 is configured to be able to suspend a baggage cart 5. Below, parts that differ from embodiment 1 will be described in detail, and like parts will be given the same reference numerals and will not be described again.

[0031] In the second embodiment, an under-cage rail 12 is formed under the car 1. The under-cage rail 12 is a mounting portion that allows a luggage cart 5 to be mounted under the car 1. The luggage cart 5 is provided with a roller 15a that also serves as a hook that allows it to be suspended from the under-cage rail 12. The luggage cart 5 is guided by the under-cage rail 12 to move below the car 1 in the elevator shaft 10, where it can be suspended and stored. The movement of the suspended luggage cart 5 may be manual or automatic.

[0032] The car door device 13 of the car 1 includes a car door drive device 3a, a car door 3b, a car door sill 3c, and an actuator, similar to the car door device 3 in the first embodiment, and also includes a lower car door drive device 3d arranged below the car door sill 3c. In the present embodiment, the car door drive device 3a is also referred to as the "upper car door drive device 3a." On the other hand, the landing door device 14 according to the present embodiment is configured with an upper landing door opening / closing device 4a, a landing door 4b, and a landing door sill 4c, and does not include a lower landing door opening / closing device 4d.

[0033] When the luggage cart 5 is suspended below the car, the car 1 needs to stop at a position higher than the landing door 4b at the boarding / alighting floor. In other words, the boarding / alighting position for loading and alighting the luggage cart 5 is set at a position where the height of the hook on the luggage cart 5 matches the height of the under-car rail 12. Fig. 3 shows a state in which the car 1 is stopped at the boarding / alighting position, and in this state, the lower car door drive device 3d installed below the car 1 and the upper landing door opening / closing device 4a are configured to face each other.

[0034] 4 is a schematic diagram showing the configuration of a car door device according to this embodiment. The detailed configuration of the car door device 3 according to this embodiment will be described with reference to FIG.

[0035] 4, the upper car door drive device 3a includes an upper housing 3a1, a right opening / closing plate 3a2, a left opening / closing plate 3a3, a left-right interlocking rope 3a4, a left-right interlocking rope pulley 3a5, a right rope fixing member 3a6, a left rope fixing member 3a7, and an upper engagement plate 3a8. The left-right interlocking rope pulleys 3a5 are disposed on the left and right sides of the upper housing 3a1, and the annular left-right interlocking rope 3a4 is wound around the left-right interlocking rope pulleys 3a5 under tension.

[0036] The left and right opening / closing plates 3a3 and 3a2 are guided by rails or the like and can move left and right relative to the upper housing 3a1. The right and left opening / closing plates 3a2 and 3a3 are fixed to the left and right interlocking ropes 3a4 by a right rope fastener 3a6 and a left rope fastener 3a7, respectively. As a result, the left and right opening / closing plates 3a3 and 3a2 move in conjunction with the movement of the left and right interlocking ropes 3a4. For example, an actuator (not shown), such as a motor, connected to the left and right interlocking rope pulleys 3a5 rotates the left and right interlocking rope pulleys 3a5, thereby moving the left and right interlocking ropes 3a4 clockwise or counterclockwise, thereby moving the left and right opening / closing plates 3a3 and 3a2 in opposite directions. The left and right car doors 3b are connected to the left and right opening / closing plates 3a3 and 3a2, respectively, and operate in conjunction with the left and right opening / closing plates 3a3 and 3a2.

[0037] The upper engagement plate 3a8, together with the upper engagement rod 4a8 of the upper landing door opening and closing device 4a, constitutes a first coupling portion. The upper engagement plate 3a8 is fixed to a portion of the left opening and closing plate 3a3 inside the upper housing 3a1. When the upper car door drive device 3a engages with the upper landing door opening and closing device 4a while the car 1 is stopped at the landing position, the upper engagement plate 3a8 pushes the upper engagement rod 4a8 of the landing door device 14, and the lock of the landing door device 4 is released. In this state, when the left opening and closing plate 3a3 and the right opening and closing plate 3a2 operate to open or close the car door 3b, the left opening and closing plate 4a3 of the landing door device 4 operates in conjunction with the left opening and closing plate 3a3, and the landing door 4b is also opened or closed as described above.

[0038] The lower car door drive device 3d includes a lower housing 3d1, a lower opening / closing plate 3d2, an upper / lower interlocking rope 3d4, a pulley for the upper / lower interlocking rope 3d5, an upper rope fixing member 3d6, a lower rope fixing member 3d7, and a lower engagement plate 3d8.

[0039] The lower engagement plate 3d8, together with the upper engagement rod 4a8 of the upper landing door opening and closing device 4a, constitutes a second connecting portion. When the car door drive device 3a and the upper landing door opening and closing device 4a are engaged with each other while the car 1 is parked at a predetermined boarding and alighting position, the lower engagement plate 3d8 rotates the lower engagement rod 4d8 of the landing door device 4 counterclockwise. This causes the landing door to be unlocked.

[0040] A total of four vertical interlocking rope pulleys 3d5 are arranged, one on each side of the upper housing 3a1 and the lower housing 3d1. A loop-shaped vertical interlocking rope 3d4 is wound around the four vertical interlocking rope pulleys 3d5 under tension. The vertical interlocking rope 3d4 is fixed to the right opening / closing plate 3a2 by an upper rope fixation 3d6 and to the lower opening / closing plate 3d2 by a lower rope fixation 3d7.

[0041] With the lower car door drive device 3d and the upper landing door opening / closing device 4a engaged, the actuator of the car door device 3 starts driving in the door opening direction, and when the left and right interlocking ropes 3a4 move counterclockwise, the right opening / closing plate 3a2 moves to the right. The upper and lower interlocking ropes 3d4 are fixed to the right opening / closing plate 3a2 by the upper rope fixation 3d6. Therefore, the upper and lower interlocking ropes 3d4 move clockwise by the right opening / closing plate 3a2. The upper and lower interlocking ropes 3d4 are fixed to the lower opening / closing plate 3d2 by the lower rope fixation 3d7. Therefore, as the upper and lower interlocking ropes 3d4 move, the lower opening / closing plate 3d2 moves in the opening direction (i.e., leftward).

[0042] The lower car door drive device 3d and the upper landing door opening and closing device 4a are engaged with each other by the second connecting portion. Therefore, the opening operation of the lower opening and closing plate 3d2 causes the left opening and closing plate 4a3 of the landing door device 14 to move in the opening direction (i.e., leftward). As a result, the left-right interlocking rope 4a4 fixed to the left opening and closing plate 4a3 moves clockwise, and as a result, the right opening and closing plate 4a2 of the landing door device 14 fixed to the left-right interlocking rope 4a4 moves in the opening direction (i.e., rightward). As a result, the landing door 4b is opened.

[0043] The closing movement of the car door 3b and the landing door 4b is the reverse of this movement. After the doors are closed, when the engagement between the lower car door drive device 3d and the lower landing door opening and closing device 4d is released, the upper engagement rod 4a8 is returned to the locked state.

[0044] In the same manner as in the first embodiment, the second embodiment is also configured so that commands for boarding and disembarking the baggage cart 15 can be input from a hall operating panel, an external terminal, or the like.

[0045] As described above, according to this embodiment, the lower car door drive device 3d that engages with the landing door device 4 to open and close the car door and landing door is provided below the upper car door drive device 3a. This makes it possible to easily take in and out the baggage cart 5 suspended below the car 1. Therefore, the space occupied by the elevator 100 can be used more effectively.

[0046] In the present embodiment, the lower car door drive device 3d is configured to operate the lower opening / closing plate 3d2 by transmitting the opening / closing operation of the right opening / closing plate 3a2 of the upper car door drive device 3a via the upper / lower interlocking rope 3d4. However, the lower car door drive device 3d may be configured to drive the upper landing door opening / closing device 4a to open or close the landing door 4b without opening or closing the car door 3b. Therefore, for example, the lower car door drive device 3d may be configured to include an actuator that directly operates only the lower opening / closing plate 4d2.

[0047] In this embodiment, the car door 3b and the landing door 4b are described as being double-swing type doors. However, the car door 3b and the landing door 4b may be, for example, single-swing type doors. In this case as well, an upper car door drive device 3a and a lower car door drive device 3d are provided above and below the car door 3b, and a mechanism is provided that enables the landing door 4b to be opened and closed by engagement with the upper landing door opening / closing device 4a, thereby similarly enabling the baggage trolley 5 to be stored in the space below the car 1.

[0048] Embodiment 3 Fig. 5 is a block diagram showing a configuration example of an elevator system according to this embodiment. As shown in Fig. 5, the elevator system according to this embodiment includes an elevator control device 101, a bogie control system 102 including a user interface 102a, one or more bogie control devices 105, a communication path 107, and a communication path 108. The bogie control system 102 can be connected to an external system via a wireless LAN or the like. The functions of the bogie control system 102, elevator control device 101, and bogie control device 105 according to this embodiment may be realized by, for example, one or more other control devices.

[0049] The functions performed by each component of the elevator system, i.e., the elevator control device 101, the bogie control system 102, and the bogie control device 105, may be implemented using a circuit including a general-purpose processor, an application-specific processor, an integrated circuit, an ASIC (Application Specific Integrated Circuits), a CPU (Central Processing Unit), a conventional circuit, or a combination thereof, programmed to perform the described functions. A processor includes transistors and other circuits and is therefore considered a circuit. A processor may execute a program stored in a memory. Furthermore, the circuits, units, and means in the embodiments are hardware programmed to perform the described functions or hardware that executes the described functions. The hardware may be any hardware disclosed in the embodiments or any hardware known to be programmed to perform the described functions or that executes the described functions. When the hardware is a processor, which can be considered a type of circuit, the circuit, means, or unit is a combination of hardware and software used to configure the hardware and / or processor.

[0050] The elevator control device 101 controls the operation of the elevator 100 described in the first embodiment. The elevator control device 101 and the cart control system 102 are connected to each other so that they can communicate with each other via a communication path 107 such as a wireless LAN. The cart control system 102 and the elevator control device 101 can communicate with each other via a serial or parallel communication path 107. The communication path 107 may be wired or wireless.

[0051] In this embodiment, the luggage carts 5 are capable of autonomous travel, and a carriage control device 105 is installed on each luggage cart 5 to control the autonomous travel of each luggage cart 5. The carriage control device 105 and the carriage control system 102 are connected via a communication path 108 such as a wireless LAN. The communication path 108 may be wired or wireless. Commands from the carriage control system 102 are transmitted to the carriage control device 105 via the communication path 108.

[0052] The user interface 102a is not limited to a specific one, but may be, for example, a touch panel screen. The vehicle control system 102 receives commands input from the user interface 102a. The vehicle control system 102 is also communicatively connected to an external system 106, such as a smart speaker, and receives commands input from the external system 106.

[0053] Fig. 6 is a flowchart showing an example of the control operation of the cart control system to control the movement of a luggage cart. Fig. 6 shows an example of the control operation when storing a luggage cart 5 on the car 1. The control operation in Fig. 6 is executed when a command to store the luggage cart 5 on the car 1 is received from the user interface 102a, the external system 106, or the cart control device 105.

[0054] As shown in Fig. 6, first, in step S2, the cart control system 102 transmits an "on-car boarding request" to the elevator control device 101 via the communication path 107. The "on-car boarding request" includes at least information about the boarding floor of the baggage cart 5 to be stored.

[0055] When the elevator control device 101 receives the "on-car boarding request," it starts moving the car 1 of the elevator 100 to the predetermined boarding / alighting position at the boarding floor for the baggage cart 5, and at the same time sends a "serving" signal to the cart control system 102. Here, as explained in the first embodiment, the "boarding / alighting position" is the position where the car door drive device 3a and the lower landing door opening / closing device 4d at the boarding floor engage with each other, and where the height of the upper surface of the car over-rail 2 is the same as the height of the floor surface 6a of the landing 6 at the boarding floor.

[0056] In step S3, the cart control system 102 determines whether or not an "in service" signal has been received from the elevator control device 101. If it is determined in step S3 that an "in service" signal has not been received, the process returns to step S3, and the determination in step S3 is repeatedly executed at predetermined control intervals until an "in service" signal is received.

[0057] On the other hand, if it is determined in step S3 that a "serving" signal has been received, then in step S4, a "movement command" to move to the boarding floor is sent to the bogie control device 105 via the communication path 108.

[0058] The cart control device 105, which has received the "movement command," moves the baggage cart 5 to the boarding position of the elevator 100. When the movement of the baggage cart 5 is completed, the cart control device 105 transmits an "arrival" signal to the cart control system 102 via the communication path 108.

[0059] Next, in step S5, the bogie control system 102 determines whether or not an "arrival" signal has been received from the bogie control device 105. If it is determined in step S5 that an "arrival" signal has not been received, the process returns to step S5, and the determination in step S5 is repeated at predetermined control intervals until an "arrival" signal is received.

[0060] If it is determined in step S5 that the "arrival" signal has been received, then in step S6, the cart control system 102 transmits a "door open command" to the elevator control device 101.

[0061] When the elevator control device 101 receives the "door open command," it drives the car door device 3 to open the landing door 4b at the boarding floor. After that, the elevator control device 101 transmits a "boarding OK" signal to the bogie control system 102.

[0062] Next, in step S7, the vehicle control system 102 determines whether or not a "boarding permitted" signal has been received. If it is determined in step S7 that a "boarding permitted" signal has not been received, the process returns to step S7, and the determination in step S7 is repeatedly executed at predetermined control intervals until a "boarding permitted" signal is received.

[0063] If it is determined in step S7 that the "boarding permitted" signal has been received, then in step S8, the bogie control system 102 transmits a "boarding command" to the bogie control device 105.

[0064] Upon receiving the "boarding command," the bogie control device 105 starts loading the baggage cart 5 onto car 1. When the loading of the baggage cart 5 onto car 1 is complete, the bogie control device 105 transmits a "boarding complete" signal to the bogie control system 102. Here, the baggage cart 5 may be structured so that the bogie portion and the power portion can be separated. In that case, if the current boarding command is to load only the bogie portion onto car 1, the bogie control device 105 transmits the "boarding complete" signal after the power portion has dismounted from car 1 of the elevator 100.

[0065] Next, in step S9, the vehicle control system 102 determines whether or not a "boarding complete" signal has been received. If it is determined in step S9 that a "boarding complete" signal has not been received, the process returns to step S9, and the determination in step S9 is repeatedly executed at predetermined control intervals until a "boarding complete" signal is received.

[0066] When the "boarding complete" signal is received in step S9, the cart control system 102 then transmits the "boarding complete" signal to the elevator control device 101 in step S10.

[0067] When the elevator control device 101 receives the "boarding complete" signal, it closes the door of car 1 of the elevator 100. When the elevator control device 101 completes closing the door, it transmits a "door closing complete" signal to the bogie control system 102.

[0068] Next, in step S11, the bogie control system 102 determines whether or not a "door closing completed" signal has been received. If it is determined in step S11 that a "door closing completed" signal has not been received, the process returns to step S11, and the determination in step S11 is repeatedly executed at predetermined control intervals until a "door closing completed" signal is received.

[0069] On the other hand, if it is determined in step S11 that a "door close" signal has been received, the current processing is completed.

[0070] The same processing is performed when the carriage control system causes a baggage carriage 5 to be unloaded. Fig. 7 is a flowchart showing an example of the control operation when the baggage carriage 5 loaded on the car 1 is unloaded. The control operation when the baggage carriage 5 is unloaded will be described with reference to Fig. 7.

[0071] The "disembarkation request" is input by the user by operating an operation input means such as a hall operating panel installed at the elevator 100 hall, an application registered on a smartphone or the like, a remote control, or the user interface 102a. When the user wants to disembark the baggage cart 5 without using the elevator 100, the user can transmit a disembarkation request requesting that the baggage cart 5 be disembarked from the operation input means described above. Also, when the user makes a hall call to board the car 1 of the elevator 100, a "temporary disembarkation request" command requesting that the baggage cart 5 be temporarily disembarked is automatically transmitted to the cart control system 102.

[0072] FIG. 7 shows an example of disembarking a baggage trolley 5 when a hall call is registered in the elevator control device 101. When a user makes an elevator hall call, for example, by pressing a hall call button on the control panel of the elevator 100, the hall call is input to the elevator control device 101. The elevator control device 101 transmits a "temporary disembarkation request" to the car control system 102. At the same time, the elevator control device 101 moves the car 1 to a boarding / disembarking position at the disembarking floor for the baggage trolley 5. That is, the elevator control device 101 moves the car 1 to a position where the lower hall door opening / closing device 4d at the disembarking floor and the car door driving device 3a face each other. The elevator control device 101 then drives the car door driving device 3a to open the hall door at the disembarking floor. When the hall door has been opened, the elevator control device 101 transmits a "disembark OK" signal to the car control system 102.

[0073] 7, the vehicle control system 102 first determines whether or not a "temporary dismount request" has been received in step S21. If it is determined in step S21 that the vehicle control system 102 has not received a "temporary dismount request," the current process ends.

[0074] If it is determined in step S21 that a "temporary dismount request" has been received, then in step S22, the vehicle control system 102 determines whether or not a "dismount permitted" signal has been received. If it is determined in step S22 that a "dismount permitted" signal has not been received, the process returns to step S22, and the determination in step S22 is repeatedly executed at predetermined control intervals until a "dismount permitted" signal is received.

[0075] On the other hand, if it is determined in step S22 that a "dismount permitted" signal has been received, then in step S23, a "temporary evacuation" signal is sent to the cart control device 105. Upon receiving the "temporary evacuation" signal, the cart control device 105 causes the baggage cart 5 to dismount from the elevator 100 and move to a predetermined temporary evacuation position. Once the baggage cart 5 has completed dismounting, the cart control device 105 transmits a "dismount completed" signal to the cart control system 102.

[0076] In step S24, the bogie control system 102 determines whether or not a "dismounting completed" signal has been received from the bogie control device 105. If it is determined in step S24 that a "dismounting completed" signal has not been received, the process returns to step S24, and the determination in step S24 is repeatedly executed at predetermined control intervals until a "dismounting completed" signal is received.

[0077] On the other hand, if it is determined in step S24 that the "descent completed" signal has been received, then in step S25 the cart control system 102 transmits a "descent completed" signal to the elevator control device 101. Having received the "descent completed" signal, the elevator control device 101 performs an elevation operation in response to a hall call from the user. When the elevation operation is completed, the elevator control device 101 transmits a "re-boarding permitted" signal to the cart control system 102.

[0078] Next, in step S26, the vehicle control system 102 determines whether or not a "re-boarding permission" signal has been received. If it is determined in step S26 that a "re-boarding permission" signal has not been received, the process returns to step S26, and the determination in step S26 is repeatedly executed at predetermined control intervals until a "re-boarding permission" signal is received.

[0079] On the other hand, if it is determined in step S26 that a "re-boarding permission" signal has been received, the process proceeds to step S27, where the trolley control system 102 controls the loading of the luggage trolley 5 onto the car, i.e., executes the control operations of steps S2 to S11 in Figure 4.

[0080] As described above, a user can automatically load the luggage cart 5 onto the car with a simple command, such as pressing a button, from the user interface 102a or an external system 106 such as a smart speaker. Also, even if the luggage cart 5 is loaded onto the car, when a user raises or lowers the elevator 100, the luggage cart 5 can be automatically lowered, making the elevator 100 ready to rise or lower. This allows the luggage cart 5 to be stored on the car 1 of the elevator 100 except during normal operation when the elevator 100 is running with users inside the car 1. Therefore, the space occupied by the elevator 100 can be used effectively.

[0081] In this embodiment, the control operations applied to the elevator 100 of embodiment 1 have been described, but the control operations described with reference to Figures 6 and 7 can also be applied to the elevator 200 of embodiment 2 in the same manner.

[0082] Although the preferred embodiments have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the claims.
