A control panel 7 and a door device 8 for opening and closing the door are provided.

  The car 3 is provided with a pair of partition floors 10a and 10b (partition members) on the side walls 9 facing each other in the car room, the positions being folded along the side wall surfaces and the position protruding toward the indoor side. The car 3 has a structure in which the car room space can be divided into two upper and lower spaces of the upper room 11 and the lower room 12 in a state where the partition floors 10a and 10b are developed. The partition floors 10a and 10b are, for example, two vertically long floor boards, frames or long platforms each having a thickness. The end portions of the partition floors 10a and 10b in the longitudinal direction are attached horizontally and in parallel through the hinge mechanism 40 on the surface of the side wall 9 facing each other. The plate surfaces of the pair of partition floors 10a and 10b both take a position facing the ceiling and a position where both the plate surfaces face the side wall surface. When the person folds and expands, the partition floors 10a and 10b are fixed at each position.

  In the elevator 1 according to the present embodiment, with the partition floors 10a and 10b being unfolded and fixed by a person, the car landing position can be moved to two positions in the height direction at the landing 13 on each floor and can be stopped. . On each floor, wheelchairs are able to get on and off at two car height positions, the upper room position and the lower room position. In the two places, the upper chamber 11 faces the lower half of the entrance / exit 15 so that the upper surface 17 (the surface on which the wheelchair wheel is grounded) of the partition floors 10 a, 10 b is flush with the landing floor 14 of the landing 13. It refers to the cage height and the cage height at which the lower chamber 12 faces the lower half of the entrance 15 so that the floor 16 of the cage 3 is flush with the landing floor 14. At the height of the car where the upper chamber 11 faces the lower half of the entrance 15, the wheelchair gets on and off with the upper surface 17 of the partition floors 10 a, 10 b as the wheel ground contact surface, and the car where the lower chamber 12 faces the lower half of the entrance 15 At the height, the car position is set so that the wheelchair gets on and off using the car floor 16 as a wheel ground contact surface.

  That is, by providing folding partition floors 10a and 10b on the car interior wall and setting the partition floors 10a and 10b when performing evacuation operation, two upper and lower spaces can be created in the car 3. ing. When the car 3 is normally stopped, a wheelchair passenger gets into the lower space, and once the door is closed, the car 3 is lowered and the door is opened, so that the wheelchair passenger can get into the upper space. .

  A partition floor switch 41 (partition detection switch) such as a micro switch is attached between the vicinity of the end of the partition floor 10a and the side wall 9 of the cab. A partition floor switch 41 is also attached between the vicinity of the end of the other partition floor 10 b and the other side wall 9. This partition floor switch 41 has a mechanism in which two contact points come in contact with and separate from each other, detects a state in which the partition floor 10a is separated from the side wall 9 and a state in which the partition floor 10a is folded on the side wall 9 and outputs a detected signal. The control panel 7 can be notified via the operation panel of the car 3. When this partition floor switch 41 detects that the position of the partition floor 10a is a horizontally expanded position, the control panel 7 can perform an operation to stop the car 3 at two locations on each floor. Yes.

  The door device 18 opens and closes the door 13 facing the landing 13 when the car is landed, and closes at other times. This door device 18 includes a pair of two landing doors 19 provided at the entrance 15 of the landing 13, a pair of two upper car doors 21 provided above the car entrance 20 of the car 3, and a car doorway 20. A pair of two lower car doors 22, an engagement device 23 for engaging the upper car door 21 with the landing door 19, and an engagement device 24 for engaging the lower car door 22 with the landing door 19. And have.

  The landing door 19 has the same panel surface as two door panels 25 and an interlock 26 (locking portion) provided above the panel surface facing the car 3 among the panel surfaces of one of the door panels 25. And an interlock 27 (locking portion) provided below. Both interlocks 26 and 27 can be engaged with the engagement device 23.

  On the other hand, on the car 3 side, the upper car door 21 and the lower car door 22 are each provided with a total of four door panels, two sets of left and right pairs. A rope-type interlocking mechanism (not shown) is provided on the side of the car 3 to give an opening / closing force to the door panels in a state where the upper ends of the four door panels are suspended. This interlocking mechanism suspends the two door panels of the lower car door 22 at a suspending position located below the suspending position of the two door panels of the upper car door 21. The two door panels of the upper car door 21 and the two door panels of the lower car door 22 are arranged with their positions shifted in the front-rear direction.

  The door opening / closing force is transmitted from the car 3 to the landing door 19 with the engaging device 23 of the upper car door 21 sandwiching the protruding member of the interlock 26. The door opening / closing force is transmitted from the car 3 to the landing door 19 with the engagement device 23 sandwiching the protruding member of the interlock 27.

  In the present embodiment, the engagement device 23 and the engagement device 24 are controlled to operate independently. Operation commands to the engagement devices 23 and 24 are issued from the control panel 7 via the car operation panel in the car 3.

  Also, a landing detection plate 28 is provided below the landing door sill of the hoistway 2 in FIG. The car 3 is provided with two landing detection switches for detecting the landing detection plate 28. One of the two landing detection switches is a normal stop landing detection switch 29. The other landing detection switch is a landing detection switch 30 for wheelchair escape operation (not shown in the figure). Two landing detection switches are shown in FIGS.

  FIG. 3 is a perspective view of the car 3 that is being opened at the landing 13. FIG. 4 is an enlarged view of the normal stop landing detection switch 29. In these drawings, the above-mentioned reference numerals represent the same elements as described above. The normal stop landing detection switch 29 is a switch used for landing detection during normal stop. The normal stop landing detection switch 29 is, for example, a photoelectric landing detector attached to one end of the car door sill. The wheelchair evacuation operation landing detection switch 30 is a switch used for landing detection when getting on and off the upper room 11 for wheelchair evacuation operation, and is provided at the center in the height direction outside the side wall of the car 3.

  More specifically, when the cab is moved up and down, the normal stop landing detection switch 29 emits light, and the landing detection plate 28 reflects this light toward the normal stop landing detection switch 29, and the landing is detected. It is detected whether or not a predetermined position on the floor to be floored has been reached. The landing detection signals from the normal stop landing detection switch 29 and the wheelchair escape operation landing detection switch 30 are sent to the control panel 7.

  As shown in FIG. 4, the normal stop landing detection switch 29 includes three landing switches 29a, 29b, and 29c. The landing switch 29a detects the descending landing zone. The landing switch 29b detects the destination floor level. The landing switch 29c detects the rising side landing zone. When the car 3 ascends and reaches the destination floor, the landing switch 29a for the lower landing zone and the landing for the destination floor level are detected by the landing detection signal from the landing detection plate 28 near the destination floor. The switch 29b is turned on in this order, and thereafter, the landing switch 29c for the rising side landing zone is turned on so that the arrival of the car 3 at the time of rising reaches the landing zone is detected. The landing detection switch 30 for wheelchair evacuation operation also has three landing switches having functions equivalent to those of the landing switches 29a, 29b, and 29c, respectively, and is the same as the detection method of the normal stop landing detection switch 29. Zone detection is performed with the detection method.

  In the elevator 1 according to the present embodiment, the partition floor switch 41 operates when the partition floors 10a and 10b on the car interior wall are lowered. Even if the car 3 is shifted half downward, the door can be opened. In addition to the normal stop landing detection switch 29, an upper space wheelchair escape operation landing detection switch 30 is also installed.

  When the elevator 1 according to the present embodiment having such a configuration performs a normal operation, the control panel 7 reads from the partition floor switch 41 that the positions of the pair of partition floors 10a and 10b are all in the folded position. The control panel 7 determines that the cab is not partitioned. In this case, the control panel 7 performs operation control of the elevator 1 in the normal mode. In the normal operation mode, the control panel 7 determines the destination floor according to the car position of the car 3, the hall call registration of the hall 13 of each floor, and the car call registration, and sends the traveling direction command and speed command to the hoist 5 Is output. By driving the hoisting machine 5, the car 3 and the counterweight 6 are moved up and down in opposite directions in the hoistway 2 through the main rope 6.

  Next, when a disaster such as a fire occurs, the control panel 7 receives a fire occurrence signal from the building side.

  FIG. 5 is a flowchart for explaining the operation control method of the elevator 1 during the evacuation operation. The control panel 7 determines whether or not the fire detector installed in the building is always operating and has received a fire detection signal (step A1). In step A1, when the fire detector is not activated, the route No is passed, and in step A2, the control panel 7 sets the operation mode of the elevator 1 to the normal operation mode. In this case, the evacuation operation control process ends.

  In step A1, when the control panel 7 receives the fire detection signal, the control panel 7 switches the operation mode of the elevator 1 to the control operation mode and notifies the in-car operation panel and the landing operation panel that a fire has occurred. Let For example, the control panel 7 moves the car 3 to the nearest floor and keeps the door open for a certain time. The control panel 7 broadcasts voice announcements in the car and speakers on each floor, and displays a warning on the display device. If the fire detector is operating, the Yes route is passed, and in step A3, the control panel 7 reads the state of the partition floor switch 41 in the car room. In step A3, when the position of the partition floors 10a and 10b is the folding position, the normal operation is performed through the No route (step A2).

  Under this circumstance, the attendant and the like tilt the partition floors 10a and 10b to incline. These partition floors 10a and 10b are set to the unfolded position, and the cab space is divided into two spaces, an upper chamber 11 and a lower chamber 12. In Step A3, when the control panel 7 detects that the partition floors 10a and 10b are in the unfolded position from the partition floor switch 41, the Yes route is passed, and in Step A4, the control panel 7 performs the operation for wheelchair evacuation. To do.

  Hereinafter, an evacuation operation in which a plurality of wheelchairs are transported from an upper floor, which is a occupancy floor of a wheelchair user, to the first floor, which is an evacuation floor, when the first basement floor exists will be described.

(1) Driving for wheelchair evacuation during boarding The driving during boarding on the residence floor will be described with reference to FIGS. The above described symbols represent the same elements. Elements denoted by the same reference numerals in these drawings are the same as each other.

  FIG. 6 is a diagram for explaining the movement from the dispatch to the residence floor to the start of the descent. As shown to Fig.6 (a), the control panel 7 dispatches the empty cage | basket | car 3 to a residence floor. An attendant or the like lowers the partition floors 10a and 10b at the folding position, and the partition floors 10a and 10 are set at the unfolded position as shown in FIG. 6B.

  FIG. 7 is a flowchart for explaining a driving control method when boarding a wheelchair.

  In step B1 of FIG. 7, the control panel 7 opens the door. As shown in FIG. 6C, the wheelchair 42 gets into the lower chamber 12 from the landing 14.

  Further, in step B2, the control panel 7 determines whether or not the door closing button on the operation panel in the car 3 or the hall 13 is pressed. While the door close button is not pressed, the route is No and the door is kept open (step B1). When it is detected in step B2 that the door closing button has been pressed, the Yes route is passed, and in step B3, the control panel 7 performs door closing. Subsequently, in step B4, the control panel 7 determines whether or not the upper car door 21 and the lower car door 22 are completely closed. When these doors are not fully closed, the No. route is passed and the control panel 7 performs the process of step B2.

  When the upper car door 21 and the lower car door 22 are completely closed in step B4, the control panel 7 passes through the Yes route and the landing detection switch 30 for wheelchair evacuation operation for getting in and out of the upper chamber 11 in step B5. Turn on monitoring. This is because the wheelchair evacuation operation landing detection switch 30 is enabled and the control panel 7 searches for an appropriate car position.

  Subsequently, in step B6, the control panel 7 operates the car 3 in the downward direction at a low speed with monitoring of the switch output from the wheelchair escape operation landing detection switch 30 enabled. The wheelchair evacuation operation landing detection switch 30 continues to photoelectrically output the reflected light from the landing detection plate 28. During this low speed operation, the control panel 7 sets the operation mode of the elevator 1 to a mode in which it is determined from the landing detection signal whether the car position is for the upper chamber 11 only in the upper space getting on / off mode.

  In step B7, the control panel 7 determines whether or not the wheelchair escape operation landing detection switch 30 has entered the correct landing zone. If a signal indicating the correct position cannot be obtained from the wheelchair evacuation operation landing detection switch 30, the control panel 7 continues the process of step B6 through the No route. When a signal indicating the correct position is received from the wheelchair evacuation operation landing detection switch 30 in step B7, the control panel 7 determines that the lower chamber position has been detected, passes the Yes route, and moves the car 3 in step B8. stop. The car 3 stops at the car position where the car floor 16 coincides with the landing floor 14. The control panel 7 opens the door. A broadcasting device or an alarm device may be attached to each hall 13 in advance, and when the door is opened, a voice announcement that the passenger can get into the upper room 11 from a speaker in the cab or the speaker in the hall 13 may be sounded. The situation where the wheelchair 42 gets in the upper chamber 11 is shown in FIG.

  Next, in step B9, the control panel 7 determines whether or not the door closing button is pressed. While the door closing button is not pressed, the control panel 7 continues to open the door (No route). When the door closing is detected, the Yes route is passed, and in step B10, the control panel 7 performs the door closing. In step B11, the control panel 7 determines whether or not the upper car door 21 and the lower car door 22 are completely closed, and determines whether or not all four door panels are closed (No route). The control panel 7 finishes the process through the Yes route. This completes the entry of the wheelchair 42 into the upper chamber 11. The control panel 7 lowers the car 3 to the first floor which is an evacuation floor. The boarding of the wheelchair 42 is completed, and the car 3 goes to the first floor as shown in FIG. 6 (e). When riding, the direction of the wheelchair 42 may be either forward or backward.

(2) Driving for wheelchair evacuation when getting off The driving when getting off the evacuation floor will be described with reference to FIGS. The above described symbols represent the same elements. Elements denoted by the same reference numerals in these drawings are the same as each other.

  FIG. 8 is a diagram for explaining the movement from landing on the evacuation floor to after getting off, and the floor in the figure represents the first floor. It is assumed that there is an underground floor below the evacuation floor so that the lowest lower end of the car does not interfere with the pit at the lowest position of the car 3. As shown in FIG. 8A, the control panel 7 causes the car 3 in a state where the wheelchair 42 is placed in the upper chamber 11 and the lower chamber 12 to land on the first floor. When the lower chamber 12 faces the entrance / exit 15 on the first floor, the control panel 7 opens and the wheelchair 42 is lowered.

  FIG. 9A is a diagram showing an arrangement relationship between the car 3 and the landing 13 when the wheelchair gets off from the lower car room. Thereby, the wheelchair 42 in the lower chamber 12 completes evacuation. When getting off, the direction of the wheelchair 42 may be either forward or backward depending on the situation.

  In addition, after the getting off is completed, the control panel 7 is moved further down on the evacuation floor while adjusting the car position, and is landed at the upper room position on the first floor. As shown in FIG. 8B, the wheelchair 42 gets off from the upper chamber 11. FIG. 9B is a diagram showing the positional relationship between the car 3 and the landing 13 when the wheelchair gets off the upper car room. Thereby, the wheelchair 42 in the upper chamber 11 completes evacuation. Then, as shown in FIG.8 (c), the person in the landing 14 folds the partition floors 10a and 10b, and returns them to the original position. Thereafter, the control panel 7 can execute the normal operation mode.

  Thus, in the elevator 1 according to the present embodiment, the cab can be divided into upper and lower parts so that more passengers in the wheelchair 42 can be placed. It becomes possible to improve the transportation efficiency of wheelchair users in the event of a disaster. For example, the transportation efficiency expressed by the number of transportation users per 5 minutes can be improved.

  When the partition floors 10a and 10b on the car interior wall are lowered, the switch operation is performed and the operation is switched to the wheelchair evacuation operation. After the wheelchair passenger gets into the lower space and closes the door, the car 3 is shifted half and the door is opened again, so that the wheelchair passenger can get into the upper space. When getting off at the evacuation floor, the wheelchair passenger in the lower space gets off, then the door is closed, the car 3 is shifted downward by half, the door is opened again, and the wheelchair passenger in the upper space gets off.

  Therefore, if the weight of the wheelchair is within the rated load capacity, twice as many wheelchair passengers as in the conventional example can be boarded.

(Modification)
The elevator according to this modified example is provided with a wheel stopper (not shown) that prevents the wheel of the wheelchair 42 that is being boarded from moving in the lower chamber 12. As an example, a wheel stopper that is allowed to appear and disappear on the floor surface 16 and extends in the front direction of the car room is installed below the car floor. Further, for the wheel stopper, an urging member for urging the wheel stopper to protrude on the floor surface 16, a fixing member for fixing the wheel stopper so as to protrude on the floor surface 16, and fixing to the wheel stopper by the fixing member. And a release member for releasing. This wheel stop is installed to function as a wheelchair safety bar.

  The appearance of the wheel stops may be automated. A drive mechanism that switches between a state in which the wheel stopper is pushed into the car floor space and a state that appears from the floor surface 16 is provided in the car floor space. Further, a switch button for turning on or off the operation of the drive mechanism is provided in the car room or on the hall operation panel. Thereby, even when a wheelchair is guided into the lower chamber 12, the wheel stopper can be raised from the floor surface 16 only by a person pressing a button.

  Since the wheelchair 42 in the upper room 11 is getting off at the landing 13 on the first floor above the first basement floor, the landing door 19 is opened, so that the wheelchair 42 is attached to the hoistway 2 and one car door panel. The elevators according to this modified example may face each other, but after riding the wheelchair 42, the safety bar is activated to improve safety and to reassure people in the lower chamber 12. Will be able to provide.

  Alternatively, the wheel stopper for preventing the wheelchair from moving may be a wheel stopper protruding in the room direction in the vicinity of the baseboard provided between the side wall 9 and the floor 16. Thereby, safety can be improved.

(Second Embodiment)
The description in the first embodiment is an example in the case of descending from the upper floor to the first floor and landing. When the upper surface 17 of the upper chamber 11 is flush with the landing floor 14 of the landing 13, there is a space for the hoistway 2 to the first basement floor, so the lower chamber 12 is positioned below the landing floor 14. We were able to. However, when the first basement floor is not provided in the building, the operation of the above embodiment cannot be executed. Alternatively, even when the building has an underground floor, when the wheelchair 42 is transported from the upper floor to the lowermost floor, the above operation cannot be performed with the cab divided into two in the basement. .

  The elevator according to the second embodiment of the present invention performs an evacuation operation in which the first floor above the floor of a building having no underground floor is an evacuation floor. In the operation by the elevator according to the present embodiment, when the car 3 is lowered from the upper floor to the lowermost floor, the wheelchair 42 in the upper chamber 11 is temporarily lowered from the lower floor to the floor before the first floor. After waiting for the user of the wheelchair 42 on the floor before the floor, the car 3 leaves this floor, moves to the evacuation floor, lowers the wheelchair 42 in the lower room 12, and returns to the floor before the first floor again. The wheelchair 42 that is waiting and coming is evacuated from the lowest floor. The configuration of this elevator is the same as the configuration of the elevator 1 of the first embodiment.

  The elevator according to the present embodiment having such a configuration normally operates when the partition floors 10a and 10b are in the folded position. On the other hand, when the control panel 7 detects that the partition floors 10a and 10b are set at the unfolded position, operation control for wheelchair evacuation is started.

(1) Driving for wheelchair evacuation during boarding The movement from the boarding on the upper floor, which is the residence floor, to the start of the lowering of the car 3 is the same as in the example of FIG. The driving control method at the time of boarding is also the same as the example of FIG.

(2) Wheelchair Evacuation Operation when Getting Off FIG. 10 is a flowchart for explaining an operation control method when getting off by an elevator according to the second embodiment of the present invention. FIG. 11 is a flowchart for explaining processing following the processing of the flowchart of FIG.

  After the entry of the wheelchair 42 into the upper chamber 11 is completed, in Step C1, the control panel 7 temporarily places the car 3 on the second floor before the first floor, which is the first floor, which is the evacuation floor. In this landing, the control panel 7 sets the operation mode to the upper space getting on / off mode. While monitoring the output of the landing detection switch 30 for wheelchair evacuation operation to determine whether the car position is the position for the lower room 12, the control panel 7 sets an appropriate car position so that the lower room 12 faces the entrance 15 Look for.

  In step C2, the control panel 7 opens the door. As shown in FIG. 12A, the wheelchair 42 gets off from the lower chamber 12 from the landing 14 on the second floor. 12A to 12E show the second floor and the first floor. A wheelchair 42 stands by at the hall 14 on the second floor. FIG. 13A is a diagram showing the positional relationship between the car 3 and the landing 13 when the wheelchair gets off from the upper car room. The in-car speaker broadcasts all users of the wheelchair 42 in the upper room 11 to call for cooperation to get off on the second floor.

  In step C3, the control panel 7 determines whether all the wheelchairs 42 have moved to the landing 14 by looking at the output of the door closing button. While the door close button is not pressed, the route is No and the door is kept open (step C2). In step C3, when the door closing button is pressed, the Yes route is passed, and in step C4, the control panel 7 closes the door. If it is not fully closed (No route of step C5), the door is kept open.

  When the fully closed state is detected in Step C5, the Yes route is passed. In Step C6, the control panel 7 turns on the monitoring of the normal stop landing detection switch 29 and lowers the car 3 by one floor. . As shown in FIG. 12B, the car 3 is stopped at a car position where the hall floor 14 of the hall 13 on the first floor and the car floor 16 are flush with each other.
