The distance increases. That is, a gap larger than the gap formed in a range other than the passing zone 1e is formed between the car 3 and the hoistway wall 1d. Therefore, after the car 3 enters the passing zone 1e from above, the car room 18 of the car 3 is moved to the hoistway wall 1d side, that is, outside until the distance between the car 3 and the hoistway wall 1d reaches a predetermined value. . Specifically, after detecting that the car 3 has entered the passing zone 1e, the pinion gear 28 is rotated by driving the motor-equipped speed reducer 26 of the car 3 to automatically move the car chamber 18 laterally. . The lateral movement direction of the cab 18 is guided by the guide rollers 25a and 25b.

  As described above, the car 2 and the car 3 are automatically moved outwardly, that is, in a direction away from each other on the vertical projection plane, in order to avoid a collision at the time of passing after entering the passing zone 1e and before passing each other. Moved sideways. Then, after a predetermined gap is formed on the vertical projection plane between the car 2 and the car 3 and the car 2 and the car 3 are arranged side by side, the car 2 and the car 3 are arranged at the same height so that they are lateral to each other. Pass through and pass. In addition, after the passing is completed, in order to return the car 2 and the car 3 to the state before the lateral movement, the car 2 and the car 3 are respectively laterally moved inward, that is, in the direction of interfering with each other on the vertical projection plane. Let Specifically, after detecting that the car 2 and the car 3 have moved to a height at which they do not interfere with each other after the passing is completed, the pinion gear 28 is driven by driving the motor-equipped speed reducer 26 of the car 2 and the car 3.

Then, after the car 2 and the car 3 are returned to the original arrangement, the car 2 and the car 3 respectively pass the passing zone 1e, the car 2 is at the stop position on the top floor, and the car 3 is at the bottom. Move toward the stop on the floor.

  In addition, when the car 2 and the car 3 enter the passing zone 1e in order to further reduce the space in the hoistway 1 by shortening the vertical distance of the passing zone 1e having a large vertical projection area, and passing each other. When passing through the zone 1e, the car 2 and the car 3 may be decelerated or stopped to sufficiently secure the time for moving the car room 18 laterally.

  Here, FIG. 10 is a main part front view showing another state of the elevator apparatus according to Embodiment 1 of the present invention, FIG. 11 is a DD arrow view of the elevator apparatus shown in FIG. 10, and the car 2 passes by. This shows a state where the vehicle stops at the stop position on the top floor after passing through the zone 1e. 10 and 11, the car 2 that stops at the stop position on the uppermost floor has the same arrangement and configuration as the car 2 that stops at the stop position on the lowermost floor. That is, the car 2 is disposed on the vertical projection plane such that the side surface of the car room 18 on the side of the hoistway wall 1c faces the hoistway wall 1c with a slight gap, and the side surface of the opposite side of the hoistway wall 1d. Are arranged between the two landing entrances and the main ropes 4 on the car 3 side, which are arranged at positions facing each other. And the car entrance 2a is arrange | positioned so that each landing entrance may be opposed in this arrangement | positioning. Further, in the range other than the passing zone 1e, the car guide rails 13a and 13b are disposed close to the hoistway wall 1c, so that the car 2 is stopped at the stop position on the top floor. The frame 19 is disposed closer to the hoistway wall 1 c side of the car room 18 and supports the car room 18. Although not shown, the car 3 stopped at the stop position on the lowermost floor has the same arrangement and configuration as the car 2 stopped at the stop position on the uppermost floor, like the car 2. Therefore, in a state where the car 2 is stopped at the top floor stop position and the car 3 is stopped at the bottom floor stop position, the portion of the car 2 where the car entrance 2a is formed and the car entrance 3a of the car 3 The portion provided with is overlapped on the vertical projection plane.

Therefore, while the car 2 and the car 3 move up and down in a range other than the passing zone 1e, that is, while moving up and down between the stop position of the lowermost floor and the lower end of the passing zone 1e, and between the upper end of the passing zone 1e and the uppermost floor. While moving up and down between the stop positions, the portion of the car 2 where the car doorway 2a is formed and the portion of the car 3 where the car doorway 3a is provided are always overlapped with each other on the vertical projection plane.

  The above-described elevator device is different from the conventional elevator device in its configuration and operation during raising / lowering. That is, the car 2 and the car 3 are operated in cooperation in the same hoistway 1 and the car room 18 is raised and lowered. Since it is configured to move in the horizontal direction, it is possible to provide a safer and more comfortable service by guiding the configuration and operation of the elevator apparatus to the passengers. Therefore, means for improving the elevator service will be described below.

  FIG. 12 is a diagram showing a passage to the elevator hall in Embodiment 1 of the present invention, FIG. 13 is a diagram showing the elevator hall in Embodiment 1 of the present invention, and FIG. 14 is a diagram of the elevator in Embodiment 1 of the present invention. FIG. 15 is a view showing a guide panel according to Embodiment 1 of the present invention, and FIG. 16 is a view showing a waiting time indicator according to Embodiment 1 of the present invention.

  12 to 16, the wall surface 30 of the passage leading to the elevator halls 10a and 10b, the wall surface 31 of the halls 10a and 10b, and the indoor wall surface 32 of the cab 18 are provided with a guide panel 33 shown in FIG. . This guide panel 33 illustrates features such as the configuration and operation of the elevator apparatus, and the precautions when the car 2 and the car 3 are raised and lowered. For example, the car 2 and the car 3 are the same. It is described briefly that the car room 18 moves in the horizontal direction during ascending / descending in order to cooperate in the hoistway 1 and avoid collision between the car 2 and the car 3. In addition, when the landings 10a and 10b are divided into exclusive use for boarding and exclusive use for getting off at each floor, the fact and the boarding and getting-off method (procedure) are also described.

  34 is a speaker provided on the wall surface 30 of the passage leading to the elevator halls 10a and 10b and the wall surface 31 of the halls 10a and 10b, and informs passengers by voice of the contents guided by the guide panel 33, and 35 is the hall Indicators provided on the wall surface 31 of 10a and 10b, 36 a landing button provided on the side of the hall entrance / exit of the wall surface 31, and 37 provided on the wall surface 31 waiting for arrival of the car 2 or the car 3 at the hall 10a. It is a waiting time indicator that displays the waiting time for the user.

  Here, although not shown, the speaker 34 is also provided in the car room 18. For example, when the car 2 and the car 3 are stopped, the contents guided by the guide panel 33 are voiced. When the passengers in the room 18 are informed and the cars 2 and 3 reach the passing zone 1e, a voice is sent to inform that the moving speed of the cars 2 and 3 changes and the car room 18 moves sideways. To notify passengers in the cab 18. The waiting time indicator 37 may have any configuration as long as it can display the waiting time until the car 2 or the car 3 arrives for the user at the hall 10a. Even if it is configured to display an hourglass, the same effect can be obtained. In addition, since the said elevator apparatus is a non-stop floor, the time required to move between the stop positions of the lowest floor and the top floor is constant. Therefore, a device having the same configuration as that of the waiting time indicator 37 may be installed in the cab 18 so that the time until arrival is displayed to passengers in the cab 18. In the first embodiment, the configuration and operation of the elevator apparatus are guided to the user by the guide panel 33 and the speaker 34 provided on each of the wall surfaces 30 to 32. For example, the configuration or operation of the elevator apparatus may be guided to the user by other guidance means such as a liquid crystal screen.

  Next, an actual service procedure of the elevator apparatus having the above-described configuration will be described with reference to FIGS. For example, in an elevator apparatus whose top floor is the target floor, such as an elevator apparatus provided in the observation tower, when the car 2 is stopped at the stop position on the bottom floor and the car 3 is stopped at the stop position on the top floor, The car 2 is a forward car that carries passengers to the destination floor, and the car 3 is a return road that carries passengers from the destination floor to the other landing. Then, at the lowest floor hall 10a, the speaker 34 informs the passenger that the car 2 is on board and waits for the passenger to ride on the car 2, and then the car door 29 and the hall door 12 The door is closed. Similarly, at the hall 10a on the top floor, the passenger is put on the car 3 and then closed. Then, after the doors 2 and 3 are closed, the driving sheave 6 is driven, the car 2 is raised, the car 3 is lowered, and the car 2 and the car 3 are moved together.

  The speaker 34 indicates that the cars 2 and 3 pass each other before the cars 2 and 3 reach the passing zone 1e after the car 2 and the car 3 start moving. The passengers in 18 are notified. When the car 2 and the car 3 reach a predetermined distance before the passing zone 1e, or reach the passing zone 1e, the ascending / descending speed is reduced from the rated speed in preparation for passing, and each car room 18 is moved outward. The If a sufficient vertical distance is not secured in the passing zone 1e for space saving of the hoistway 1, the car 2 and the car 3 are stopped and then the car rooms 18 are moved laterally. You may comprise as follows. Then, after the passing between the car 2 and the car 3 is completed, when the car rooms 18 are moved inward and returned to the state before the lateral movement, the ascending / descending speed is accelerated to the rated speed. When the above-described operations of the car 2 and the car 3 are performed, that is, when the raising / lowering speed is increased / decreased or the car room 18 is laterally moved, the car room 18 is requested to respond appropriately to passengers in the car room 18. You may make it implement guidance to the effect of implementing each operation | movement from the provided speaker 34. FIG.

  When the car 2 arrives at the stop position on the top floor and the car 3 arrives at the stop position on the bottom floor, the car door 29 and the door 12 leading to the landing 10b on the getting-off side are opened, and each car room 18 is opened. The passenger inside is taken down to the landing 10b.

  When the passengers who were at the bottom floor 10a are transported to the top floor 10b and the passengers at the top floor 10a are transported to the bottom floor 10b by the above service procedure, the car 3 is now the passenger. The forward car transported to the floor, the car 2 is the return car transporting passengers from the destination floor to the other landing. Then, the passengers at the lowest floor hall 10a are transported to the top floor hall 10b and the passengers at the top floor hall 10a are transported to the bottom floor hall 10b by the same procedure as the service procedure. That is, at the landings 10a on the lowermost floor and the uppermost floor, the speaker 34 notifies the passenger that the car 2 or the car 3 is on standby, and the passenger is boarded on the car 2 and the car 3 and then closed. The Then, after the door closing is completed, the car 2 and the car 3 are moved together to raise the car 3 and lower the car 2.

  The speaker 34 indicates that the cars 2 and 3 pass each other before the cars 2 and 3 reach the passing zone 1e after the car 2 and the car 3 start moving. The passengers in 18 are notified. Then, after the car 2 and the car 3 reach a predetermined height, the raising / lowering speed is reduced, the lateral movement to the outside of each car room 18, the passing, the lateral movement to the inside of each car room 18, and the acceleration of the raising / lowering speed are increased. Each operation is performed sequentially. When the above operations of the car 2 and the car 3 are performed, a guidance that the respective operations are performed from the speaker 34 provided in the car room 18 in order to obtain an appropriate response for passengers in the car room 18.

  When the car 3 arrives at the stop position on the top floor and the car 2 arrives at the stop position on the bottom floor, the car door 29 and the boarding door 12 leading to the landing 10b are opened, and passengers in each car room 18 are opened. To the landing 10b. By the above operation, the car 2 stops at the lowest floor landing and the car 3 stops at the top floor landing and returns to the initial state (state (a)). Continue to transport.

  According to Embodiment 1 of the present invention, even in an elevator apparatus in which two cars 2 and 3 moving up and down in one hoistway 1 in opposite directions are suspended in a fishing bottle manner by a suspension means, Space saving of the hoistway 1 can be realized. That is, in the hoistway 1, only the range necessary for the operation of the car 2 and the car 3 to avoid a collision, that is, only the passing zone 1e, the car 2 and the car 3 do not interfere with each other. It is only necessary to secure a predetermined vertical projection area that can be juxtaposed, and the other ranges of the hoistway 1 are the vertical projection area of the car 2 or the car 3, the hoistway wall 1d side of the car 2, and the raising and lowering of the car 3. It is only necessary to secure a predetermined vertical projection area smaller than the vertical projection area of the car 2 or the car 3 formed on the road wall 1c side and through which the main rope 4 passes. Therefore, it is not necessary to secure a vertical projection area in which the car 2 and the car 3 can be arranged side by side without interfering with each other, that is, the hoistway space for the two cars, ie, the car 2 and the car 3 do not interfere with each other. The occupied space can be greatly reduced.

  Further, in the passing zone 1e, each cab 18 is moved laterally, so that the collision between the car 2 and the car 3 can be avoided with a simple configuration. In order to avoid a collision by moving only each car room 18 sideways, the car frame 19 can be arranged on the vertical projection plane even when the car 2 and the car 3 are arranged at any height of the hoistway 1. There is no change. Therefore, the car guide rails 13a and 13b, 14a and 14b can be arranged in a straight line over the upper and lower sides of the hoistway 1, respectively, and there is no possibility of deteriorating work efficiency in the installation and adjustment. Further, there is no change in the arrangement of the main rope 4 on the vertical projection plane, and it is possible to prevent the main rope 4 and the hoistway walls 1c and 1d from contacting each other.

  In addition, the car entrances formed in the car rooms 18 of the car 2 and the car 3 are the same entrance / exit when the car 2 and the car 3 stop at the same landing (for example, the landing provided on the top floor). It is arrange | positioned facing. For this reason, it is not necessary to provide a separate landing entrance for each of the cars 2 and 3, and it can be configured at low cost, and can further contribute to space saving.

  In addition, the elevator device is configured to move horizontally while the car room 18 is raised and lowered, but the configuration and operation of the elevator device are notified to the passengers by various guide means. It is possible to provide a comfortable operation service without giving passengers anxiety or requesting the operation of the kite. In addition, a passenger's irritation feeling can also be eliminated by providing the waiting time indicator 37 in the wall surfaces 31 and 32.

  In the first embodiment, each of the car rooms 18 of the car 2 and the car 3 is configured to be movable in the horizontal direction. However, one of the car rooms 18 of the car 2 and the car 3 is arranged in the horizontal direction. Even if it is configured to be movable and only the car room 18 of one of the cars 2 or 3 is moved laterally in order to avoid a collision in the passing zone 1e, the same effect as described above can be obtained. It is.

  Moreover, since the elevator apparatus in Embodiment 1 can implement | achieve the space saving of the hoistway 1 more when the range other than the passing zone 1e is long, it is especially effective for an elevator apparatus with a long hoisting stroke. It becomes a means. However, in an elevator apparatus having a long up-and-down stroke, the length of the suspension means is inevitably increased, so that the extension of the suspension means reaches a predetermined value in a relatively short period. Therefore, when the extension of the suspension means becomes large, a step formed between the floor surface of the car 2 and the car 3 and the floor surface of the landings 10a and 10b becomes prominent, and the passenger gets into this step when getting on and off. This can happen. Therefore, in the following, the suspension position detecting device provided in the elevator apparatus for detecting an abnormality in the stop position of the car 2 and the car 3 and a stop position abnormality when detected by the stop position detecting means are suspended. A description will be given of a step eliminating means for absorbing the elongation generated in the means so as to eliminate the step by accommodating the step within a predetermined height.
