DETAILED DESCRIPTION OF THE INVENTION

[0009] Embodiment 1 Fig. 1 is a side view showing an elevator apparatus according to embodiment 1. Fig. 2 is a top view showing the elevator apparatus of Fig. 1. In the figure, a machine room 2 is provided above a hoistway 1. In the machine room 2, a hoisting machine 3, a deflector sheave 4, and a control device (not shown) are installed.

[0010] The hoist 3 has a hoist main body 5 and a drive sheave 6. The drive sheave 6 is provided on the hoist main body 5. The hoist main body 5 has a hoist motor and a hoist brake. The hoist motor generates driving force to rotate the drive sheave 6 under the control of a control device. The hoist brake keeps the drive sheave 6 stationary. The hoist brake also brakes the rotation of the drive sheave 6. The control device controls the operation of the elevator device.

[0011] A suspension body 7 is wound around the drive sheave 6 and the deflector sheave 4. As the suspension body 7, a plurality of ropes or a plurality of belts is used.

[0012] As shown in FIG. 1 , a car 8 and a counterweight 9 are provided in the hoistway 1 so as to be movable up and down. The car 8 is connected to a first end of a suspension body 7. The counterweight 9 is connected to a second end of the suspension body 7. The car 8 and the counterweight 9 are suspended in the hoistway 1 by the suspension body 7. The car 8 and the counterweight 9 move up and down in the hoistway 1 by rotating the drive sheave 6.

[0013] A first car guide rail 11, a second car guide rail 12, a first weight guide rail 13, and a second weight guide rail 14 are provided as multiple guide rails in the elevator shaft 1. The first car guide rail 11, the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14 are each arranged along the vertical direction.

[0014] Each of the multiple floors in the building is provided with a landing entrance 15. On each floor, the elevator shaft 1 is open to the landing through the landing entrance 15. The frontage direction of each landing entrance 15 coincides with the width direction of the elevator shaft 1. Each landing entrance 15 is opened and closed by a pair of landing doors.

[0015] As shown in Fig. 2, the first car guide rail 11 and the second car guide rail 12 face each other in the width direction of the elevator shaft 1. The car 8 is disposed between the first car guide rail 11 and the second car guide rail 12. The car 8 is movable in the vertical direction along each of the first car guide rail 11 and the second car guide rail 12.

[0016] The first weight guide rail 13 and the second weight guide rail 14 face each other in the width direction of the elevator shaft 1. The distance between the first weight guide rail 13 and the second weight guide rail 14 is smaller than the distance between the first car guide rail 11 and the second car guide rail 12.

[0017] The first weight guide rail 13 and the second weight guide rail 14 are installed at a position farther from the landing entrance / exit 15 in the depth direction of the hoistway 1 than the first car guide rail 11 and the second car guide rail 12. The depth direction of the hoistway 1 is a direction that is perpendicular to the width direction of the hoistway 1 and is horizontal.

[0018] The counterweight 9 is disposed between the first weight guide rail 13 and the second weight guide rail 14. The counterweight 9 is movable in the up and down direction along each of the first weight guide rail 13 and the second weight guide rail 14. Note that the counterweight 9 is not shown in FIG. 2.

[0019] The car 8 can stop at each of a plurality of floors. As shown in FIG.

[0020] The car body 81 is provided with a car entrance (not shown). The car entrance is opened and closed by a pair of car doors (not shown). At a floor where the car 8 is stopped, a pair of hall doors are linked with a pair of car doors, thereby opening and closing the car entrance and the hall entrance 15.

[0021] The lower guide device 82 is provided at the bottom of the car main body 81. The lower guide device 82 is guided by each of the first car guide rail 11 and the second car guide rail 12. The lower guide device 82 has a pair of lower contact portions 821. Of the pair of lower contact portions 821, one lower contact portion 821 contacts the first car guide rail 11, and the other lower contact portion 821 contacts the second car guide rail 12.

[0022] The upper guide device 83 is provided on the upper part of the car main body 81. The upper guide device 83 is guided by each of the first car guide rail 11 and the second car guide rail 12. The upper guide device 83 has a pair of upper contact portions 831. Of the pair of upper contact portions 831, one upper contact portion 831 contacts the first car guide rail 11, and the other upper contact portion 831 contacts the second car guide rail 12.

[0023] In the elevator shaft 1, a lower guide stop level and an upper guide stop level are set corresponding to each floor. The lower guide stop level corresponding to each floor is set at a height position that is lower than the landing floor 16 on that floor by a set dimension L. The upper guide stop level corresponding to each floor is set at a height position that is higher than the top of the landing entrance / exit 15 on that floor. In this embodiment, of two adjacent floors, the height position of the upper guide stop level corresponding to the lower floor is set at a height position that is lower than the height position of the lower guide stop level corresponding to the upper floor.

[0024] When the car 8 is stopped on any of a plurality of floors, the lower guide device 82 is disposed at a height position of the lower guide stop level corresponding to the floor on which the car 8 is stopped. Also, when the car 8 is stopped on any of a plurality of floors, the upper guide device 83 is disposed at a height position of the upper guide stop level corresponding to the floor on which the car 8 is stopped. Therefore, in this embodiment, regardless of the floor on which the car 8 is stopped, the lower guide device 82 is disposed at a height position that is lower by the set dimension L than the landing floor 16 on the floor on which the car 8 is stopped.

[0025] At least one of the plurality of floors at which the car 8 can stop is set as a specific floor. In this embodiment, all of the plurality of floors at which the car 8 can stop are set as specific floors.

[0026] A plurality of connecting structures 21 are provided in the hoistway 1. The connecting structures 21 are respectively arranged corresponding to specific floors. When the hoistway 1 is viewed from above, each connecting structure 21 is arranged outside the area of ​​the car 8 and the counterweight 9.

[0027] At each specific floor, the connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the corresponding lower guide stop level. In other words, the connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at the specific floor.

[0028] The first car guide rail 11 is connected to the second car guide rail 12 via each connecting structure 21. In other words, the second car guide rail 12 is connected to the first car guide rail 11 via each connecting structure 21. That is, the first car guide rail 11 and the second car guide rail 12 are connected to each other via each connecting structure 21.

[0029] Each connecting structure 21 has a rail connecting member 22. The rail connecting member 22 has a first attachment member 31, a second attachment member 32, an intermediate connecting member 33, and a front connecting member .

[0030] The first mounting member 31 is attached to the back surface of the first car guide rail 11. The first mounting member 31 is an angle member that extends along the depth direction of the elevator shaft 1. At each specific floor, the first mounting member 31 is attached to the back surface of the first car guide rail 11 at a height position corresponding to the lower guide stop level.

[0031] The second mounting member 32 is attached to the back surface of the second car guide rail 12. The second mounting member 32 is an angle member that extends along the depth direction of the elevator shaft 1. At each specific floor, the second mounting member 32 is attached to the back surface of the second car guide rail 12 at a height position corresponding to the lower guide stop level.

[0032] When the hoistway 1 is viewed from above, the intermediate connecting member 33 is disposed between the car 8 and the counterweight 9. The intermediate connecting member 33 is attached to each of the first mounting member 31 and the second mounting member 32. As a result, the first mounting member 31 and the second mounting member 32 are connected to each other via the intermediate connecting member 33. The intermediate connecting member 33 is an angle member that extends along the width direction of the hoistway 1.

[0033] When the hoistway 1 is viewed from above, the front connecting member 34 is disposed at a position closer to the landing of a specific floor than the car 8. The front connecting member 34 is attached to each of the first mounting member 31 and the second mounting member 32. As a result, the first mounting member 31 and the second mounting member 32 are connected to each other via the front connecting member 34. The front connecting member 34 is an angle member that extends along the width direction of the hoistway 1.

[0034] Therefore, when the elevator shaft 1 is viewed from above, the rail connecting member 22 surrounds the area of ​​the car 8. The first car guide rail 11 and the second car guide rail 12 are connected to each other via a first mounting member 31, an intermediate connecting member 33, and a second mounting member 32. The first car guide rail 11 and the second car guide rail 12 are also connected to each other via the first mounting member 31, a front connecting member 34, and the second mounting member 32.

[0035] 3 is a perspective view showing the connecting structure 21 of FIG. 2. The first mounting member 31 is provided with a pair of rail clips 17 and a pair of fasteners 18. The side portion of the first car guide rail 11 is gripped between each rail clip 17 and the first mounting member 31 by the tightening force of each fastener 18. In this way, the first mounting member 31 is attached to the back surface of the first car guide rail 11.

[0036] The second mounting member 32 is also provided with a pair of rail clips 17 and a pair of fasteners 18. The side portion of the second car guide rail 12 is gripped between each rail clip 17 and the second mounting member 32 by the tightening force of each fastener 18. In this way, the second mounting member 32 is attached to the back surface of the second car guide rail 12.

[0037] The intermediate connecting member 33 is attached to each of the first mounting member 31 and the second mounting member 32 by welding. The front connecting member 34 is attached to each of the first mounting member 31 and the second mounting member 32 by welding. The intermediate connecting member 33 and the front connecting member 34 may be connected to the first mounting member 31 and the second mounting member 32 by bolts and nuts, respectively.

[0038] The control device performs controlled operation, for example, when an earthquake occurs. Controlled operation is an operation in which, when an earthquake occurs, the car 8 is stopped at the nearest floor and the car entrance and the hall entrance 15 are opened at the nearest floor where the car 8 has stopped. During controlled operation, the control device opens the car entrance and the hall entrance 15 at the nearest floor where the car 8 has stopped, and then closes the car entrance and the hall entrance 15 to suspend operation of the elevator device.

[0039] Next, the operation will be explained. For example, if an earthquake occurs, the elevator device will perform controlled operation under the control of the control device. When controlled operation is performed, the car 8 will stop at the nearest floor, and the car entrance and hall entrance 15 will open at the nearest floor where the car 8 has stopped. This will allow passengers in the car 8 to escape to the hall at the nearest floor. After this, the car entrance and hall entrance 15 will close, and the elevator will cease operation. After this, with the car 8 stopped at the nearest floor, the elevator device will be subjected to shaking caused by the earthquake.

[0040] In this embodiment, all of the multiple floors are specific floors. Therefore, the floor nearest to where the car 8 stops is the specific floor. When the car 8 stops at the specific floor, the connecting structure 21 is disposed at the height position where the lower guide device 82 stops.

[0041] When an earthquake occurs and car 8 is stopped at a specific floor, the inertial force of car 8 generated by the shaking of the earthquake acts on each of the first car guide rail 11 and the second car guide rail 12 via each of the lower guide device 82 and the upper guide device 83. At this time, each of the first car guide rail 11 and the second car guide rail 12 receives the inertial force of car 8 from the lower guide device 82 as a lower rail load P1, and receives the inertial force of car 8 from the upper guide device 83 as an upper rail load P2.

[0042] The position of the center of gravity of the car 8 is biased toward a position closer to the lower part of the car 8 than to the upper part of the car 8. Therefore, the magnitude of the lower rail load P1 is greater than the upper rail load P2.

[0043] When the first car guide rail 11 receives a lower rail load P1 from the lower guide device 82, the lower rail load P1 is distributed from the first car guide rail 11 to the second car guide rail 12 via the connecting structure 21. Furthermore, when the second car guide rail 12 receives the lower rail load P1 from the lower guide device 82, the lower rail load P1 is distributed from the second car guide rail 12 to the first car guide rail 11 via the connecting structure 21. As a result, the magnitude of the lower rail load P1 borne by each of the first car guide rail 11 and the second car guide rail 12 is reduced, and deformation of each of the first car guide rail 11 and the second car guide rail 12 is suppressed.

[0044] In such an elevator device, the first car guide rail 11 and the second car guide rail 12 are connected to each other via a connecting structure 21. Furthermore, the connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at a specific floor. Therefore, in the event of an earthquake, for example, the lower guide device 82 can be stopped at the height position where the connecting structure 21 is located.

[0045] Here, consider a case where the lower guide device 82 is stopped at a position vertically separated from the height position of the connecting structure 21. In this case, when the first car guide rail 11 receives the inertial force of the car 8 from the lower guide device 82, the first car guide rail 11 becomes more likely to bend depending on the distance from the connecting structure 21 to the lower guide device 82. Furthermore, when the second car guide rail 12 receives the inertial force of the car 8 from the lower guide device 82, the second car guide rail 12 becomes more likely to bend depending on the distance from the connecting structure 21 to the lower guide device 82. For this reason, when the lower guide device 82 is stopped at a position vertically separated from the height position of the connecting structure 21, the inertial force of the car 8 received by each of the first car guide rail 11 and the second car guide rail 12 from the lower guide device 82 is less likely to be transmitted to the connecting structure 21.

[0046] In this embodiment, the lower guide device 82 can be stopped at the height position where the connecting structure 21 is arranged. This allows the inertial force of the car 8, which is received by each of the first car guide rail 11 and the second car guide rail 12 from the lower guide device 82, to be effectively transmitted to the connecting structure 21. Therefore, the inertial force of the car 8 can be efficiently distributed to each of the first car guide rail 11 and the second car guide rail 12, and the magnitude of the inertial force of the car 8 borne by each of the first car guide rail 11 and the second car guide rail 12 can be reduced. This makes it possible to more reliably suppress deformation of each of the first car guide rail 11 and the second car guide rail 12. Therefore, it is possible to prevent damage to each of the first car guide rail 11 and the second car guide rail 12. It is also possible to prevent at least one of the first car guide rail 11 and the second car guide rail 12 from interfering with equipment in the hoistway 1.

[0047] Furthermore, the position of the center of gravity of the car 8 is biased to a position closer to the lower part of the car 8 than to the upper part of the car 8. For this reason, the magnitude of the inertial force acting on the car 8 from the lower guide device 82 on each of the first car guide rail 11 and the second car guide rail 12 is greater than the magnitude of the inertial force acting on the car 8 from the upper guide device 83. This makes it possible to more efficiently transmit the inertial force of the car 8 from each of the first car guide rail 11 and the second car guide rail 12 to the connecting structure 21. Therefore, it is possible to more reliably suppress deformation of each of the first car guide rail 11 and the second car guide rail 12.

[0048] In the first embodiment, the intermediate connecting member 33 and the front connecting member 34 are each formed as an angle member. However, as shown in Fig. 4, the intermediate connecting member 33 and the front connecting member 34 may each be formed as a rod-shaped member having a circular cross section. In this case, the rod-shaped member is attached to the first mounting member 31 and the second mounting member 32, respectively, with a plurality of nuts.

[0049] Embodiment 2 FIG. 5 is a top view showing an elevator apparatus according to embodiment 2. The rail connecting member 22 in each connecting structure 21 has a first mounting member 31, a second mounting member 32, and an intermediate connecting member 33. The configurations of the first mounting member 31, the second mounting member 32, and the intermediate connecting member 33 are the same as those in embodiment 1. In this embodiment, the front connecting member 34 of embodiment 1 is not included in the rail connecting member 22. Other configurations in this embodiment are the same as those in embodiment 1.

[0050] In this way, even if the front connecting member 34 is not included in the rail connecting member 22, the first car guide rail 11 and the second car guide rail 12 can be connected to each other via the first mounting member 31, the second mounting member 32, and the intermediate connecting member 33. Therefore, the inertial force of the car 8 can be distributed to each of the first car guide rail 11 and the second car guide rail 12. This makes it possible to more reliably suppress deformation of each of the first car guide rail 11 and the second car guide rail 12.

[0051] Embodiment 3 6 is a top view showing an elevator apparatus according to Embodiment 3. The first car guide rail 11 is connected to each of the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14 via rail connecting members 22 in each connecting structure 21. The second car guide rail 12 is connected to each of the first car guide rail 11, the first weight guide rail 13, and the second weight guide rail 14 via rail connecting members 22 in each connecting structure 21.

[0052] The rail connecting member 22 in each connecting structure 21 has a first mounting member 31, a second mounting member 32, a front connecting member 34, a rear connecting member 35, a first intervening member 36, and a second intervening member 37. The configurations of the first mounting member 31, the second mounting member 32, and the front connecting member 34 are the same as those in the first embodiment.

[0053] When the hoistway 1 is viewed from above, the rear connecting member 35 is disposed at a position farther from the landing of the specific floor than the counterweight 9. When the hoistway 1 is viewed from above, the rear connecting member 35 is disposed between the first mounting member 31 and the second mounting member 32. The rear connecting member 35 is attached to each of the first mounting member 31 and the second mounting member 32. As a result, the first mounting member 31 and the second mounting member 32 are connected to each other via the rear connecting member 35. The rear connecting member 35 is an angle member that extends along the width direction of the hoistway 1.

[0054] The first intervening member 36 is interposed between the back surface of the first weight guide rail 13 and the first mounting member 31. The first intervening member 36 is attached to the first mounting member 31 by welding. The first intervening member 36 is attached to the back surface of the first weight guide rail 13 by a pair of rail clips and a pair of fasteners. Therefore, the first mounting member 31 is attached to the back surface of the first weight guide rail 13 via the first intervening member 36.

[0055] The second intervening member 37 is interposed between the back surface of the second weight guide rail 14 and the second mounting member 32. The second intervening member 37 is attached to the second mounting member 32 by welding. The second intervening member 37 is attached to the back surface of the second weight guide rail 14 by a pair of rail clips and a pair of fasteners. Therefore, the second mounting member 32 is attached to the back surface of the second weight guide rail 14 via the second intervening member 37.

[0056] Therefore, when the elevator shaft 1 is viewed from above, the rail connecting member 22 surrounds the area of ​​the car 8 and the area of ​​the counterweight 9 together. The first car guide rail 11, the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14 are connected to one another via the rail connecting member 22. Other configurations in this embodiment are the same as those in the first embodiment.

[0057] In such an elevator apparatus, the first car guide rail 11 is connected to each of the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14 via the connecting structure 21. Furthermore, the second car guide rail 12 is connected to each of the first car guide rail 11, the first weight guide rail 13, and the second weight guide rail 14 via the connecting structure 21. Therefore, the inertial force of the car 8 received by the first car guide rail 11 from the lower guide device 82 can be distributed to each of the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14. Furthermore, the inertial force of the car 8 received by the second car guide rail 12 from the lower guide device 82 can be distributed to each of the first car guide rail 11, the first weight guide rail 13, and the second weight guide rail 14. This makes it possible to more reliably suppress deformation of each of the first car guide rail 11 and the second car guide rail 12.

[0058] In the third embodiment, the rail connecting members 22 in each connecting structure 21 may have an intermediate connecting member 33 similar to that in the first embodiment. In this case, the first mounting member 31 and the second mounting member 32 are connected to each other via the intermediate connecting member 33. The intermediate connecting member 33 is disposed between the car 8 and the counterweight 9 when the hoistway 1 is viewed from above.

[0059] Embodiment 4 7 is a top view showing an elevator apparatus according to Embodiment 4. The first car guide rail 11 is connected to each of the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14 via rail connecting members 22 in each connecting structure 21. The second car guide rail 12 is connected to each of the first car guide rail 11, the first weight guide rail 13, and the second weight guide rail 14 via rail connecting members 22 in each connecting structure 21.

[0060] The rail connecting member 22 in each connecting structure 21 has a first mounting member 31, a second mounting member 32, an intermediate connecting member 33, a first intervening member 36, and a second intervening member 37. The configurations of the first mounting member 31, the second mounting member 32, the first intervening member 36, and the second intervening member 37 are the same as those in embodiment 3. The rail connecting member 22 in each connecting structure 21 does not have the front connecting member 34 and the rear connecting member 35 in embodiment 3.

[0061] The configuration of the intermediate connecting member 33 is the same as in embodiment 1. That is, the intermediate connecting member 33 is attached to each of the first mounting member 31 and the second mounting member 32. As a result, the first mounting member 31 and the second mounting member 32 are connected to each other via the intermediate connecting member 33. When the hoistway 1 is viewed from above, the intermediate connecting member 33 is disposed between the car 8 and the counterweight 9. The intermediate connecting member 33 is an angle member that extends along the width direction of the hoistway 1. Other configurations in this embodiment are the same as in embodiment 3.

[0062] In this way, the first mounting member 31 and the second mounting member 32 are connected to each other via the intermediate connecting member 33. Even in this way, the first car guide rail 11 can be connected to each of the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14 via the connecting structure 21. Furthermore, the second car guide rail 12 can be connected to each of the first car guide rail 11, the first weight guide rail 13, and the second weight guide rail 14 via the connecting structure 21. Therefore, deformation of each of the first car guide rail 11 and the second car guide rail 12 can be more reliably suppressed.

[0063] Embodiment 5. 8 is a top view showing an elevator apparatus according to Embodiment 5. The first car guide rail 11 is connected to the first weight guide rail 13 via the rail connecting members 22 in each connecting structure 21. The second car guide rail 12 is connected to the second weight guide rail 14 via the rail connecting members 22 in each connecting structure 21.

[0064] The rail connecting member 22 in each connecting structure 21 has a first mounting member 31, a second mounting member 32, a first intervening member 36, and a second intervening member 37. The configurations of the first mounting member 31, the second mounting member 32, the first intervening member 36, and the second intervening member 37 are the same as those in embodiment 4. The rail connecting member 22 in each connecting structure 21 does not have the intermediate connecting member 33 in embodiment 4.

[0065] The first car guide rail 11 is connected to the first weight guide rail 13 via a first mounting member 31 and a first intervening member 36. The second car guide rail 12 is connected to the second weight guide rail 14 via a second mounting member 32 and a second intervening member 37. The first car guide rail 11 and the first weight guide rail 13 are not connected to the second car guide rail 12 and the second weight guide rail 14. Other configurations in this embodiment are similar to those in the fourth embodiment.

[0066] In this elevator apparatus, the first car guide rail 11 is connected to the first weight guide rail 13 via the connecting structure 21. Furthermore, the second car guide rail 12 is connected to the second weight guide rail 14 via the connecting structure 21. Therefore, the inertial force of the car 8 received by the first car guide rail 11 from the lower guide device 82 can be effectively distributed to the first weight guide rail 13. Furthermore, the inertial force of the car 8 received by the second car guide rail 12 from the lower guide device 82 can be effectively distributed to the second weight guide rail 14. This makes it possible to more reliably suppress deformation of the first car guide rail 11 and the second car guide rail 12.

[0067] Embodiment 6 FIG. 9 is a top view showing an elevator apparatus according to embodiment 6. The elevator apparatus has a first unit 10, a second unit 20, and a plurality of connecting structures 21. The elevator apparatus has the first unit 10 and the second unit 20 as a plurality of elevator units. The configuration of each of the first unit 10 and the second unit 20 is the same as the configuration of the elevator apparatus according to embodiment 1, excluding the plurality of connecting structures 21.

[0068] The first unit 10 and the second unit 20 are installed side by side in positions adjacent to each other. The elevator shafts 1 corresponding to the first unit 10 and the second unit 20 are provided in an elevator shaft setting space, which is a single space in a building. As a result, within the elevator shaft setting space, the two elevator shafts 1 corresponding to the first unit 10 and the second unit 20 are adjacent to each other in the width direction of the elevator shaft setting space.

[0069] Each of the first and second elevators 10 and 20 includes a first car guide rail 11, a second car guide rail 12, a first weight guide rail 13, and a second weight guide rail 14 as a plurality of guide rails.

[0070] The cars 8 of the first car 10 and the second car 20 can stop at multiple floors in the building. In the elevator shaft setting space, a lower guide stop level and an upper guide stop level are set corresponding to each floor. The height positions of the lower guide stop level and the upper guide stop level relative to the landing floor 16 on each floor are the same as in the first embodiment.

[0071] In each of the first machine 10 and the second machine 20, when the car 8 is stopped on any of a plurality of floors, the lower guide device 82 is disposed at a height position of the lower guide stop level corresponding to the floor on which the car 8 is stopped. Also, when the car 8 is stopped on any of a plurality of floors, the upper guide device 83 is disposed at a height position of the upper guide stop level corresponding to the floor on which the car 8 is stopped.

[0072] At least one of the multiple floors at which the car 8 of each of the first elevator 10 and the second elevator 20 can stop is designated as a specific floor. In this embodiment, all of the multiple floors at which the car 8 of each of the first elevator 10 and the second elevator 20 can stop are designated as specific floors.

[0073] A plurality of connecting structures 21 are provided in the elevator shaft setting space. The connecting structures 21 are respectively arranged corresponding to each specific floor. When the elevator shaft setting space is viewed from above, each connecting structure 21 is arranged outside the area of ​​the car 8 and counterweight 9 of the first elevator 10, and outside the area of ​​the car 8 and counterweight 9 of the second elevator 20.

[0074] The height position of each connecting structure 21 in the elevator shaft space is the same as the height position of the connecting structure 21 in embodiment 1. Therefore, the connecting structures 21 are each disposed at the height position of the lower guide stop level corresponding to each specific floor.

[0075] The plurality of guide rails in each of the first unit 10 and the second unit 20 are connected to each other via respective connecting structures 21.

[0076] Either the first elevator 10 or the second elevator 20 is designated as the reference elevator, and the elevators other than the reference elevator are designated as other elevators. In this case, the first car guide rail 11 of the reference elevator is connected to each of the plurality of guide rails in each of the first elevator 10 and the second elevator 20, other than the first car guide rail 11 of the reference elevator, via a connecting structure 21. In addition, the second car guide rail 12 of the reference elevator is connected to each of the plurality of guide rails in each of the first elevator 10 and the second elevator 20, other than the second car guide rail 12 of the reference elevator, via a connecting structure 21.

[0077] In the first elevator 10, the connecting structures 21 are attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at a specific floor. In the second elevator 20, the connecting structures 21 are attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at a specific floor. Therefore, in both the reference elevator and the other elevators, each connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at a specific floor.

[0078] Each connecting structure 21 has a plurality of rail connecting members 22 and inter-rail car connecting members 23 .

[0079] The rail connecting members 22 are arranged corresponding to the first unit 10 and the second unit 20, respectively. Therefore, in this embodiment, the number of rail connecting members 22 included in the connecting structure 21 is two. The configuration of each rail connecting member 22 is the same as in embodiment 3. As a result, in the first unit 10, each of the multiple guide rails in the first unit 10 is connected to each other via the corresponding rail connecting members 22. In the second unit 20, each of the multiple guide rails in the second unit 20 is connected to each other via the corresponding rail connecting members 22.

[0080] In each connecting structure 21, a rail connecting member 22 corresponding to the first unit 10 and a rail connecting member 22 corresponding to the second unit 20 are adjacent to each other. Two adjacent rail connecting members 22 are connected to each other via an inter-unit connecting member 23.

[0081] Therefore, the first car guide rail 11 of the reference car is connected to each of the multiple guide rails in the reference car and other cars, other than the first car guide rail 11, via the inter-car connecting member 23 and two rail connecting members 22. In addition, the second car guide rail 12 of the reference car is also connected to each of the multiple guide rails in the reference car and other cars, other than the second car guide rail 12, via the inter-car connecting member 23 and two rail connecting members 22.

[0082] The inter-car connecting member 23 has a plurality of connection members 41. In the present embodiment, the number of connection members 41 included in the inter-car connecting member 23 is two.

[0083] Each connecting member 41 is disposed between two adjacent rail connecting members 22. Each connecting member 41 is attached to each of the two adjacent rail connecting members 22. Each connecting member 41 is disposed along the width direction of the elevator shaft space. In each connecting structure 21, one of the two connecting members 41 is attached to the end of the rail connecting member 22 closer to the landing of the specific floor, and the other is attached to the end of the rail connecting member 22 farther from the landing of the specific floor.

[0084] In this embodiment, a single angle member is formed by two front connecting members 34 and one connecting member 41. Also, in this embodiment, a single angle member is formed by two rear connecting members 35 and the other connecting member 41. Other configurations of this embodiment are the same as those of the first embodiment.

[0085] In such an elevator system, of the plurality of guide rails in the reference car and the other cars, the first car guide rail 11 of the reference car is connected to each of the guide rails other than the first car guide rail 11 of the reference car via a connecting structure 21. Furthermore, of the plurality of guide rails in the reference car and the other cars, the second car guide rail 12 of the reference car is connected to each of the guide rails other than the second car guide rail 12 of the reference car via a connecting structure 21. Furthermore, in the reference car, the connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at a specific floor.

[0086] Therefore, in the event of an earthquake, for example, the lower guide device 82 can be stopped in the reference car at the height position where the connecting structure 21 is located. As a result, in the reference car, the inertial force of the car 8 that is received by each of the first car guide rail 11 and the second car guide rail 12 from the lower guide device 82 can be effectively transmitted to the connecting structure 21. Therefore, the inertial force of the car 8 received by the first car guide rail 11 of the reference car can be dispersed not only to guide rails other than the first car guide rail 11 of the reference car, but also to the guide rails of the other cars. Furthermore, the inertial force of the car 8 received by the second car guide rail 12 of the reference car can be dispersed not only to guide rails other than the second car guide rail 12 of the reference car, but also to the guide rails of the other cars. This makes it possible to more reliably suppress deformation of the first car guide rail 11 and the second car guide rail 12 in the reference car.

[0087] Embodiment 7 10 is a top view showing an elevator apparatus according to Embodiment 7. Each connecting structure 21 has a plurality of rail connecting members 22 and inter-car connecting members 23.

[0088] The rail connecting members 22 are arranged corresponding to the first unit 10 and the second unit 20, respectively. Therefore, in this embodiment, the number of rail connecting members 22 included in the connecting structure 21 is two. The configuration of each rail connecting member 22 is the same as in embodiment 4. As a result, in the first unit 10, each of the multiple guide rails in the first unit 10 is connected to each other via the corresponding rail connecting members 22. In the second unit 20, each of the multiple guide rails in the second unit 20 is connected to each other via the corresponding rail connecting members 22.

[0089] Two adjacent rail connecting members 22 are connected to each other via an inter-rail connecting member 23. The inter-rail connecting member 23 has a connection member 41. In this embodiment, the number of connection members 41 included in the inter-rail connecting member 23 is one.

[0090] The connecting member 41 is disposed between two adjacent rail connecting members 22. The connecting member 41 is attached to each of the two adjacent rail connecting members 22. The connecting member 41 is disposed along the width direction of the elevator shaft space. In this embodiment, the two intermediate link members 33 and the connecting member 41 form a single angle member. Other configurations of this embodiment are the same as those of embodiment 6.

[0091] As described above, in this embodiment, the rail connecting members 22 corresponding to each of the first rail unit 10 and the second rail unit 20 are configured in the same manner as in the fourth embodiment, and the number of connecting members 41 in the inter-rail unit connecting member 23 is one. Therefore, similar to the sixth embodiment, the multiple guide rails in each of the first rail unit 10 and the second rail unit 20 can be connected to each other via the connecting structure 21.

[0092] As a result, the first car guide rail 11 of the reference car can be connected to each of the guide rails other than the first car guide rail 11 of the reference car among the plurality of guide rails in the reference car and the other cars via the connecting structure 21. Furthermore, the second car guide rail 12 of the reference car can be connected to each of the guide rails other than the second car guide rail 12 of the reference car among the plurality of guide rails in the reference car and the other cars via the connecting structure 21. Therefore, deformation of each of the first car guide rail 11 and the second car guide rail 12 of the reference car can be more reliably suppressed.

[0093] Embodiment 8 FIG. 11 is a top view showing an elevator apparatus according to embodiment 8. The elevator apparatus has a first elevator 10, a second elevator 20, a third elevator 30, and a plurality of connecting structures 21. The elevator apparatus has a plurality of elevators, namely, the first elevator 10, the second elevator 20, and the third elevator 30. The configuration of each of the first elevator 10, the second elevator 20, and the third elevator 30 is the same as the configuration of the elevator apparatus according to embodiment 1, excluding the plurality of connecting structures 21.

[0094] The first unit 10, the second unit 20, and the third unit 30 are installed in a line in the order of the first unit 10, the second unit 20, and the third unit 30. The elevator shafts 1 corresponding to the first unit 10, the second unit 20, and the third unit 30 are provided in an elevator shaft setting space, which is a single space in the building. Within the elevator shaft setting space, three elevator shafts 1 corresponding to the first unit 10, the second unit 20, and the third unit 30 are lined up in the width direction of the elevator shaft setting space.

[0095] Each of the first machine 10, the second machine 20 and the third machine 30 includes a first car guide rail 11, a second car guide rail 12, a first weight guide rail 13 and a second weight guide rail 14 as multiple guide rails.

[0096] The cars 8 of the first car 10, the second car 20, and the third car 30 can stop at multiple floors in the building. In the elevator shaft setting space, a lower guide stop level and an upper guide stop level are set corresponding to each floor. The height positions of the lower guide stop level and the upper guide stop level relative to the landing floor 16 on each floor are the same as in the first embodiment.

[0097] In each of the first, second, and third elevators 10, 20, and 30, when the car 8 is stopped on any of a plurality of floors, the lower guide device 82 is disposed at a height position of the lower guide stop level corresponding to the floor on which the car 8 is stopped. Also, in each of the first, second, and third elevators 10, 20, and 30, when the car 8 is stopped on any of a plurality of floors, the upper guide device 83 is disposed at a height position of the upper guide stop level corresponding to the floor on which the car 8 is stopped.

[0098] At least one of the multiple floors at which the car 8 of each of the first elevator 10, the second elevator 20, and the third elevator 30 can stop is designated as a specific floor. In this embodiment, all of the multiple floors at which the car 8 of each of the first elevator 10, the second elevator 20, and the third elevator 30 can stop are designated as specific floors.

[0099] A plurality of connecting structures 21 are provided in the elevator shaft setting space. The connecting structures 21 are respectively arranged corresponding to each specific floor. When the elevator shaft setting space is viewed from above, each connecting structure 21 is arranged outside the area of ​​each of the cars 8 and counterweights 9 of the first elevator 10, the second elevator 20, and the third elevator 30.

[0100] The height position of each connecting structure 21 in the elevator shaft space is the same as the height position of the connecting structure 21 in the first embodiment. Therefore, the connecting structures 21 are disposed at the height position of the lower guide stop level corresponding to each specific floor. Furthermore, in each of the first car 10, the second car 20, and the third car 30, the connecting structures 21 are attached to the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at the specific floor.

[0101] The first car guide rail 11 in the first car 10 is connected to the second car guide rail 12 in the second car 20 via a connecting structure 21. The second car guide rail 12 in the first car 10 is connected to the second weight guide rail 14 in the first car 10 via a connecting structure 21.

[0102] That is, of first elevator 10, second elevator 20, and third elevator 30, first elevator 10 is designated as the reference elevator, and the elevators other than the reference elevator are designated as other elevators. At this time, the first car guide rail 11 of the reference elevator is connected to the second car guide rail 12 of the other elevator adjacent to the reference elevator via a connecting structure 21. Also, at this time, the second car guide rail 12 of the reference elevator is connected to the second weight guide rail 14 of the reference elevator via the connecting structure 21.

[0103] The first car guide rail 11 in the second machine 20 is connected to the second car guide rail 12 in the third machine 30 via a connecting structure 21. The second car guide rail 12 in the second machine 20 is connected to the first car guide rail 11 in the first machine 10 via a connecting structure 21.

[0104] That is, of the first elevator 10, the second elevator 20, and the third elevator 30, the second elevator 20 is designated as the reference elevator, and the elevators other than the reference elevator are designated as other elevators. At this time, the first car guide rail 11 of the reference elevator is connected to the second car guide rail 12 of the other elevator adjacent to the reference elevator via the connecting structure 21. Also, at this time, the second car guide rail 12 of the reference elevator is connected to the first car guide rail 11 of the other elevator adjacent to the reference elevator via the connecting structure 21.

[0105] The first car guide rail 11 in the third machine 30 is connected to the first weight guide rail 13 in the third machine 30 via a connecting structure 21. The second car guide rail 12 in the third machine 30 is connected to the first car guide rail 11 in the second machine 20 via a connecting structure 21.

[0106] That is, of the first elevator 10, the second elevator 20, and the third elevator 30, the third elevator 30 is designated as the reference elevator, and the elevators other than the reference elevator are designated as other elevators. At this time, the first car guide rail 11 of the reference elevator is connected to the first weight guide rail 13 of the reference elevator via the connecting structure 21. Also, at this time, the second car guide rail 12 of the reference elevator is connected to the first car guide rail 11 of the other elevator adjacent to the reference elevator via the connecting structure 21.

[0107] Also, any one of the first car 10, the second car 20, and the third car 30 is set as the reference car. At this time, the connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 of the reference car at the height position of the lower guide device 82 when the car 8 of the reference car is stopped at a specific floor.

[0108] Each connecting structure 21 has a plurality of rail connecting members 22 and a plurality of inter-railway connecting members 23. In this embodiment, a rail connecting member 22 is provided for each of the first railway 10 and the third railway 30. In addition, in this embodiment, an inter-railway connecting member 23 is provided between the first railway 10 and the second railway 20, and between the second railway 20 and the third railway 30, respectively.

[0109] The rail connecting member 22 provided in the first elevator 10 has a second mounting member 32 and a second intervening member 37. The configurations of the second mounting member 32 and the second intervening member 37 are the same as those in the fifth embodiment. The second mounting member 32 is attached to the back surface of the second car guide rail 12 in the first elevator 10. The second mounting member 32 is attached to the back surface of the second weight guide rail 14 in the first elevator 10 via the second intervening member 37. In the first elevator 10, the second car guide rail 12 is connected to the second weight guide rail 14 via the rail connecting member 22.

[0110] The rail connecting member 22 provided in the third elevator 30 has a first mounting member 31 and a first intervening member 36. The configurations of the first mounting member 31 and the first intervening member 36 are the same as those in the fifth embodiment. The first mounting member 31 is attached to the back surface of the first car guide rail 11 in the third elevator 30. The first mounting member 31 is attached to the back surface of the first weight guide rail 13 in the third elevator 30 via the first intervening member 36. In the third elevator 30, the first car guide rail 11 is connected to the first weight guide rail 13 via the rail connecting member 22.

[0111] Each inter-rail car connecting member 23 has a pair of rail mounting members 42 and a plurality of connecting members 43. In this embodiment, the number of connecting members 43 included in each inter-rail car connecting member 23 is two.

[0112] In the inter-car connecting member 23 provided between the first car 10 and the second car 20, one of a pair of rail mounting members 42 is attached to the back surface of the first car guide rail 11 of the first car 10, and the other is attached to the back surface of the second car guide rail 12 of the second car 20. The pair of rail mounting members 42 are connected to each other via two connecting members 43. As a result, the first car guide rail 11 of the first car 10 and the second car guide rail 12 of the second car 20 are connected to each other via the inter-car connecting member 23.

[0113] In the inter-car connecting member 23 provided between the second car 20 and the third car 30, one of a pair of rail mounting members 42 is attached to the back surface of the first car guide rail 11 of the second car 20, and the other is attached to the back surface of the second car guide rail 12 of the third car 30. The pair of rail mounting members 42 are connected to each other via two connecting members 43. As a result, the first car guide rail 11 of the second car 20 and the second car guide rail 12 of the third car 30 are connected to each other via the inter-car connecting member 23. Other configurations in this embodiment are similar to those in embodiment 1.

[0114] In this elevator system, if the first elevator 10 is designated as the reference elevator and the elevators other than the reference elevator are designated as other elevators, the first car guide rail 11 of the reference elevator is connected to the second car guide rail 12 of the second elevator 20, which is the other elevator, via the connecting structure 21. The second car guide rail 12 of the reference elevator is connected to the second weight guide rail 14 of the reference elevator via the connecting structure 21. This allows the inertial force of the car 8 received by the first car guide rail 11 of the reference elevator to be dispersed to the guide rails of the other elevators. This also allows the inertial force of the car 8 received by the second car guide rail 12 of the reference elevator to be dispersed to the second weight guide rail 14 of the reference elevator. This more reliably suppresses deformation of the first car guide rail 11 and the second car guide rail 12 of the reference elevator, the first elevator 10.

[0115] Furthermore, if the second elevator 20 is designated as the reference elevator and the elevators other than the reference elevator are designated as the other elevators, the first car guide rail 11 of the reference elevator is connected to the second car guide rail 12 of the third elevator 30, which is the other elevator, via the connecting structure 21. The second car guide rail 12 of the reference elevator is connected to the first car guide rail 12 of the first elevator 10, which is the other elevator, via the connecting structure 21. Therefore, the inertial force of the car 8 received by each of the first car guide rail 11 and the second car guide rail 12 of the reference elevator can be dispersed to the guide rails of the other elevators. This makes it possible to more reliably suppress deformation of each of the first car guide rail 11 and the second car guide rail 12 in the second elevator 20, which is the reference elevator.

[0116] Furthermore, if the third elevator 30 is designated as the reference elevator and the elevators other than the reference elevator are designated as the other elevators, the first car guide rail 11 of the reference elevator is connected to the first weight guide rail 13 of the reference elevator via the connecting structure 21. The second car guide rail 12 of the reference elevator is connected to the first car guide rail 11 of the second elevator 20, which is the other elevator, via the connecting structure 21. Therefore, the inertial force of the car 8 received by the first car guide rail 11 of the reference elevator can be dispersed to the first weight guide rail 13 of the reference elevator. Furthermore, the inertial force of the car 8 received by the second car guide rail 12 of the reference elevator can be dispersed to the guide rails of the other elevators. This makes it possible to more reliably suppress deformation of the first car guide rail 11 and the second car guide rail 12 of the reference elevator 30.

[0117] Embodiment 9 Figure 12 is a side view showing an elevator apparatus according to a ninth embodiment. The height dimension from the landing floor 16 on the lowest floor to the landing floor 16 on the floor immediately above the lowest floor is defined as the lowest height dimension h0. Furthermore, of two floors adjacent to each other in the vertical direction, the height dimension from the landing floor 16 on the lower floor excluding the lowest floor to the landing floor 16 on the upper floor is defined as the inter-floor height dimension h1. In this case, the lowest height dimension h0 is larger than the inter-floor height dimension h1. In this embodiment, all of the multiple floors at which the car 8 can stop are defined as specific floors.

[0118] A lower guide stop level and an upper guide stop level are set for each floor in the elevator shaft 1. The height positions of the lower guide stop level and the upper guide stop level relative to the landing floor 16 of each floor are the same as in the first embodiment.

[0119] Therefore, when the car 8 is stopped on any of the plurality of floors, the lower guide device 82 is disposed at the height position of the lower guide stop level corresponding to the floor on which the car 8 is stopped. Also, when the car 8 is stopped on any of the plurality of floors, the upper guide device 83 is disposed at the height position of the upper guide stop level corresponding to the floor on which the car 8 is stopped.

[0120] The height position of each connecting structure 21 in the elevator shaft 1 is the same as the height position of the connecting structure 21 in embodiment 1. Therefore, the connecting structures 21 are each disposed at the height position of the lower guide stop level corresponding to each specific floor.

[0121] In this embodiment, of two specific floors adjacent to each other in the vertical direction, the height position of the upper guide stop level corresponding to the lower specific floor other than the lowest floor is the same as the height position of the lower guide stop level corresponding to the upper specific floor. As a result, of two specific floors adjacent to each other in the vertical direction, when the car 8 is stopped at the lower specific floor other than the lowest floor, the upper guide device 83 is arranged at the height position of the lower guide device 82 when the car 8 is stopped at the upper specific floor. Therefore, when the car 8 is stopped at a specific floor other than the lowest floor, the lower guide device 82 is arranged at the height position of the connecting structure 21 corresponding to that specific floor, and the upper guide device 83 is arranged at the height position of the connecting structure 21 corresponding to the floor immediately above that specific floor.

[0122] In car 8, the height dimension from lower guide device 82 to upper guide device 83 matches the inter-floor height dimension h1. Upper guide device 83 is attached to car body 81 via height adjustment member 84. In car 8, the dimension of height adjustment member 84 is adjusted so that the height dimension from lower guide device 82 to upper guide device 83 matches the inter-floor height dimension h1. Other configurations in this embodiment are the same as those in embodiment 1.

[0123] In this elevator system, when the car 8 is stopped at the lower specific floor of two specific floors adjacent to each other in the vertical direction, the upper guide device 83 is disposed at the same height as the lower guide device 82 when the car 8 is stopped at the upper specific floor. Therefore, the lower guide device 82 can be stopped at the height position of the connecting structure 21 corresponding to the specific floor at which the car 8 is stopped, and the upper guide device 83 can be stopped at the height position of the connecting structure 21 corresponding to the floor immediately above the specific floor at which the car 8 is stopped. This allows the first car guide rail 11 and the second car guide rail 12 to effectively transmit to the connecting structure 21 not only the inertial force of the car 8 acting from the lower guide device 82 but also the inertial force of the car 8 acting from the upper guide device 83. This further reduces the magnitude of the inertial force of the car 8 borne by each of the first car guide rail 11 and the second car guide rail 12. This further reliably suppresses deformation of each of the first car guide rail 11 and the second car guide rail 12.

[0124] In the ninth embodiment, the configuration in which the height position of the upper guide device 83 when the car 8 is stopped at a specific lower floor and the height position of the lower guide device 82 when the car 8 is stopped at a specific upper floor coincide with each other is applied to the first embodiment. However, the configuration in which the height position of the upper guide device 83 when the car 8 is stopped at a specific lower floor and the height position of the lower guide device 82 when the car 8 is stopped at a specific upper floor coincide with each other may also be applied to the second to fifth embodiments.

[0125] In addition, a configuration in which the height position of the upper guide device 83 when the car 8 is stopped at a specific lower floor matches the height position of the lower guide device 82 when the car 8 is stopped at a specific upper floor may be applied to at least one of the first machine 10 and the second machine 20 in embodiments 6 and 7.

[0126] In addition, a configuration in which the height position of the upper guide device 83 when the car 8 is stopped at a specific lower floor matches the height position of the lower guide device 82 when the car 8 is stopped at a specific upper floor may be applied to at least one of the first car 10, the second car 20 and the third car 30 in embodiment 8.

[0127] Furthermore, in the first to fifth and ninth embodiments, the first car guide rail 11 may be connected to at least one of the second car guide rail 12, the first weight guide rail 13, and the second weight guide rail 14 via the connecting structure 21. For example, the first car guide rail 11 may be connected only to the second weight guide rail 14 via the connecting structure 21. In this way, the inertial force of the car 8 that is received by the first car guide rail 11 from the lower guide device 82 can be dispersed to the other guide rails via the connecting structure 21.

[0128] Furthermore, in the first to fifth and ninth embodiments, the second car guide rail 12 may be connected to at least one of the first car guide rail 11, the first weight guide rail 13, and the second weight guide rail 14 via the connecting structure 21. For example, the second car guide rail 12 may be connected only to the first weight guide rail 13 via the connecting structure 21. In this way, the inertial force of the car 8 that the second car guide rail 12 receives from the lower guide device 82 can be dispersed to the other guide rails via the connecting structure 21.

[0129] Furthermore, in Embodiments 6 to 8, it is sufficient that the first car guide rail 11 of the reference elevator car is connected to at least one of the plurality of guide rails in each of the plurality of elevator cars, other than the first car guide rail 11 of the reference elevator car, via the connecting structure 21. For example, the first car guide rail 11 of the reference elevator car may be connected only to the second weight guide rail 14 of the other elevator car via the connecting structure 21. In this way, the inertial force of the car 8 that is received by the first car guide rail 11 of the reference elevator car from the lower guide device 82 can be dispersed to the other guide rails via the connecting structure 21.

[0130] Furthermore, in Embodiments 6 to 8, it is sufficient that second car guide rail 12 in the reference car is connected to at least one of the plurality of guide rails in each of the plurality of elevator cars, other than second car guide rail 12 in the reference car, via connecting structure 21. For example, second car guide rail 12 in the reference car may be connected only to first weight guide rail 13 in the other car via connecting structure 21. In this way, the inertial force of car 8 that is received by second car guide rail 12 in the reference car from lower guide device 82 can be dispersed to the other guide rail via connecting structure 21.

[0131] Furthermore, in the first to fifth and ninth embodiments, the connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at a specific floor. However, only the height position at which the connecting structure 21 is attached to the first car guide rail 11 may be made to coincide with the height position of the lower guide device 82 when the car 8 is stopped at a specific floor.

[0132] Even in this way, the inertial force of the car 8 received by each of the first car guide rail 11 and the second car guide rail 12 from the lower guide device 82 can be transmitted to the connecting structure 21. In particular, the inertial force of the car 8 received by the first car guide rail 11 from the lower guide device 82 can be transmitted effectively to the connecting structure 21. This makes it possible to suppress deformation of each of the first car guide rail 11 and the second car guide rail 12.

[0133] Also, only the height position at which the connecting structure 21 is attached to the second car guide rail 12 may be made to coincide with the height position of the lower guide device 82 when the car 8 is stopped at a specific floor.

[0134] Even in this way, the inertial force of the car 8 received by each of the first car guide rail 11 and the second car guide rail 12 from the lower guide device 82 can be transmitted to the connecting structure 21. In particular, the inertial force of the car 8 received by the second car guide rail 12 from the lower guide device 82 can be transmitted effectively to the connecting structure 21. This makes it possible to suppress deformation of each of the first car guide rail 11 and the second car guide rail 12.

[0135] That is, the connecting structure 21 only needs to be attached to at least one of the first car guide rail 11 and the second car guide rail 12 at the height position of the lower guide device 82 when the car 8 is stopped at a specific floor.

[0136] Furthermore, in the sixth to eighth embodiments, the connecting structure 21 is attached to each of the first car guide rail 11 and the second car guide rail 12 in the reference car at the height position of the lower guide device 82 when the car 8 of the reference car is stopped at the specific floor. However, in the reference car, only the height position at which the connecting structure 21 is attached to the first car guide rail 11 may be made to coincide with the height position of the lower guide device 82 when the car 8 is stopped at the specific floor.

[0137] Even in this way, in the reference vehicle, the inertial force of the car 8 received by each of the first car guide rail 11 and the second car guide rail 12 from the lower guide device 82 can be transmitted to the connecting structure 21. In particular, in the reference vehicle, the inertial force of the car 8 received by the first car guide rail 11 from the lower guide device 82 can be transmitted effectively to the connecting structure 21. This makes it possible to suppress deformation of each of the first car guide rail 11 and the second car guide rail 12 in the reference vehicle.

[0138] In addition, in the reference car, only the height position at which the connecting structure 21 is attached to the second car guide rail 12 may be made to match the height position of the lower guide device 82 when the car 8 is stopped at a specific floor.

[0139] Even in this way, in the reference vehicle, the inertial force of the car 8 received by each of the first car guide rail 11 and the second car guide rail 12 from the lower guide device 82 can be transmitted to the connecting structure 21. In particular, in the reference vehicle, the inertial force of the car 8 received by the second car guide rail 12 from the lower guide device 82 can be transmitted effectively to the connecting structure 21. This makes it possible to suppress deformation of each of the first car guide rail 11 and the second car guide rail 12 in the reference vehicle.

[0140] In other words, the connecting structure 21 only needs to be attached to at least one of the first car guide rail 11 and the second car guide rail 12 of the reference car at the height position of the lower guide device 82 when the car 8 of the reference car is stopped at a specific floor.

[0141] Furthermore, in the first to fifth and ninth embodiments, the connecting structure 21 may be provided in the hoistway 1 when an existing elevator system is renovated. Furthermore, in the sixth to eighth embodiments, the connecting structure 21 may be provided in the hoistway space when an existing elevator system is renovated. In this way, by applying the connecting structure 21 to the renovation work of the elevator system, the earthquake resistance function of the existing elevator system can be easily improved.
