[0025] By guiding each guide device 208 by the guide rail 3, the under-carriage gondola device 2 is guided by the guide rail 3.

[0026] An under-carriage work space 209 for an under-carriage worker 6 to enter is formed in the under-carriage gondola 202. The gondola handrail device 207 is used by the under-carriage worker 6 who works in the under-carriage work space 209.

[0027] FIG. 2 is a side view showing a main part of the elevator device of FIG. 1. In the hoistway 4, a plurality of landing door devices 7 are arranged side by side in the longitudinal direction of the hoistway 4. Of a pair of adjacent landing door devices 7, the upper landing door device 7 is defined as a first landing door device 701, and the lower landing door device 7 of a pair of adjacent landing door devices 7 is defined as a second landing door device 702.

[0028] When maintenance inspections of the first landing door device 701 and the second landing door device 702 are performed, the overhead work space 104 is arranged adjacent to the first landing door device 701. By arranging the overhead work space 104 adjacent to the first landing door device 701, the overhead worker 5 in the overhead work space 104 can reach the first landing door device 701, and maintenance inspection of the first landing door device 701 becomes possible.

[0029] In addition, when maintenance inspections of the first landing door device 701 and the second landing door device 702 are performed, the under-carriage work space 209 is arranged adjacent to the second landing door device 702. By arranging the under-carriage work space 209 adjacent to the second landing door device 702, the under-carriage worker 6 in the under-carriage work space 209 can reach the second landing door device 702, enabling maintenance inspection of the second landing door device 702.

[0030] The support device 201 supports the under-carriage gondola 202 so that the distance between the overhead work space 104 and the under-carriage work space 209 can be adjusted.

[0031] The distance between a pair of adjacent landing door devices 7 varies depending on the height of the floor where each of the pair of landing door devices 7 is arranged. When the overhead work space 104 is adjacent to the first landing door device 701, the support device 201 supports the under-carriage gondola 202 so that the under-carriage work space 209 is adjacent to the second landing door device 702.

[0032] The car 1 further has a fall prevention member 105 provided at the lower part of the car body 101. The fall prevention member 105 is arranged in the gap between the car body 101 and the landing door device 7 when viewed from above. When the car body 101 moves up and down, the fall prevention member 105 is removed from the car body 101. By arranging the fall prevention member 105 in the gap between the car body 101 and the landing door device 7 when viewed from above, when a tool held by the overhead worker 5 falls from the overhead worker 5, the fallen tool is prevented from falling below the car body 101. Note that the fall prevention member 105 may be provided on the landing door device 7 or the wall of the hoistway 4 instead of the car body 101.

[0033] FIG. 3 is an enlarged view showing the under-car gondola device 2 in FIG. 2. The support device 201 of the under-car gondola device 2 further has a pair of fixing main ropes 210. The upper part of each fixing main rope 210 is connected to the car body 101 of the car 1. The lower part of each fixing main rope 210 is connected to the under-car gondola 202. The lower part of each fixing main rope 210 is detachable from the under-car gondola 202.

[0034] When the under-car gondola 202 moves up and down with respect to the car body 101, the lower part of the fixing main rope 210 is removed from the under-car gondola 202. When the distance between the upper-car working space 104 and the under-car working space 209 is adjusted and the up and down movement of the under-car gondola 202 with respect to the car body 101 is stopped, the lower part of the fixing main rope 210 is connected to the under-car gondola 202.

[0035] By connecting the fixing main rope 210 to the under-car gondola 202, the downward movement of the under-car gondola 202 with respect to the car body 101 is restricted. Therefore, by connecting the fixing main rope 210 to the under-car gondola 202, the downward movement of the under-car working space 209 with respect to the upper-car working space 104 is restricted.

[0036] Note that the upper part of the fixing main rope 210 may be configured to be detachable from the car body 101. In this configuration, when the under-car gondola 202 moves up and down with respect to the car body 101, the upper part of the fixing main rope 210 is removed from the car body 101. When the distance between the upper-car working space 104 and the under-car working space 209 is adjusted and the up and down movement of the under-car gondola 202 with respect to the car body 101 is stopped, the upper part of the fixing main rope 210 is connected to the car body 101.

[0037] FIG. 4 is a plan view showing the car 1 in FIG. 1. The upper-car handrail device 103 has a pair of lateral handrail parts 106 and a rear handrail part 107.

[0038] Each lateral handrail part 106 is arranged at intervals in the width direction of the boarding entrance and exit. Also, each lateral handrail part 106 is arranged facing each other in the width direction of the boarding entrance and exit. Further, each lateral handrail part 106 is arranged so as to extend in the depth direction of the boarding entrance and exit.

[0039] When viewed from above, the rear handrail part 107 is arranged so that the rear handrail part 107 and the rear part in the depth direction in the cage 1 overlap each other. Also, the rear handrail part 107 is arranged across a pair of lateral handrail parts 106. Further, the rear handrail part 107 is connected to the rear part in the depth direction of the boarding entrance and exit in each lateral handrail part 106.

[0040] Note that the cage upper handrail device 103 does not have a front handrail part connected to the front part in the depth direction of the boarding entrance and exit in a pair of lateral handrail parts 106.

[0041] FIG. 5 is a plan view showing the cage lower gondola 202 of FIG. 1. The gondola handrail device 207 has a pair of lateral handrail parts 211, a rear handrail part 212, and a front handrail part 213.

[0042] Each lateral handrail part 211 is arranged at intervals in the width direction of the boarding entrance and exit. Also, each lateral handrail part 211 is arranged facing each other in the width direction of the boarding entrance and exit. Further, each lateral handrail part 211 is arranged so as to extend in the depth direction of the boarding entrance and exit.

[0043] When viewed from above, the rear handrail part 212 is arranged so that the rear handrail part 212 and the rear part in the depth direction in the floor plate part 206 overlap each other. Also, the rear handrail part 212 is arranged across a pair of lateral handrail parts 211. Further, the rear handrail part 212 is connected to the rear part in the depth direction of the boarding entrance and exit in each lateral handrail part 211.

[0044] The front handrail portion 213 is arranged such that, when viewed from above, the front handrail portion 213 and the front portion in the depth direction of the floor plate portion 206 overlap each other. The front handrail portion 213 is arranged across a pair of side handrail portions 211. Further, the front handrail portion 213 is connected to the front portion in the depth direction of the boarding entrance of each side handrail portion 211.

[0045] The front handrail portion 213 has a pair of handrail pieces 214 divided in the width direction of the boarding entrance. FIG. 6 is a view showing a state in which the pair of handrail pieces 214 of the under-car gondola device 2 in FIG. 5 has moved. The pair of handrail pieces 214 is movable between a closed position in which the pair of handrail pieces 214 are connected to each other in the width direction of the boarding entrance and an open position in which the pair of handrail pieces 214 are separated from each other in the width direction of the boarding entrance.

[0046] When the under-car worker 6 performs maintenance and inspection in the under-car work space 209, the under-car worker 6 sets the positions of the pair of handrail pieces 214 to the open position. When the positions of the pair of handrail pieces 214 are in the open position, the under-car worker 6 in the under-car work space 209 can reach the boarding door device 7, and maintenance and inspection of the boarding door device 7 becomes possible.

[0047] On the other hand, when the under-car gondola 202 moves up and down together with the car 1, the under-car worker 6 sets the positions of the pair of handrail pieces 214 to the closed position. Further, when the under-car gondola 202 moves up and down with respect to the car body 101, the under-car worker 6 sets the positions of the pair of handrail pieces 214 to the closed position. When the positions of the pair of handrail pieces 214 are in the closed position, the under-car worker 6 in the under-car work space 209 cannot reach the boarding door device 7. Thereby, it is possible to prevent the under-car gondola 202 from moving up and down while the hand of the under-car worker 6 reaches the boarding door device 7.

[0048] FIG. 7 is a block diagram showing the elevator device of FIG. 1. The elevator device according to the first embodiment includes a car upper operation device 8 and a gondola operation device 9.

[0049] The car-top operating device 8 is provided on the car 1. The car-top operating device 8 is operated by the car-top worker 5 in the car-top work space 104. The car-top operating device 8 has a car lift button 801. The car lift button 801 is a spring-back type button. Therefore, the car lift button 801 is in an operated state only when it is pushed down. Examples of the car lift button 801 include a button that causes the car 1 to rise when operated and a button that causes the car 1 to lower when operated.

[0050] The car lift button 801 is connected to the elevator control panel 10. The elevator control panel 10 controls the ascent and descent of the car 1. When the car lift button 801 is operated, a car lift signal is input from the car lift button 801 to the elevator control panel 10. When the car lift button 801 is operated, the car 1 ascends and descends.

[0051] The gondola operating device 9 is provided on the under-car gondola 202. The gondola operating device 9 is operated by the under-car worker 6 in the under-car work space 209. The gondola operating device 9 has a gondola lift button 901, a car liftable button 902, and a gondola control device 903. Each of the gondola lift button 901 and the car liftable button 902 is a spring-back type button. Therefore, the gondola lift button 901 is in an operated state only when it is pushed down, and the car liftable button 902 is in an operated state only when it is pushed down. Examples of the gondola lift button 901 include a button that causes the under-car gondola 202 to rise when operated and a button that causes the under-car gondola 202 to lower when operated.

[0052] The gondola lift button 901 is connected to the gondola control device 903. The car liftable button 902 is connected to the elevator control panel 10. The gondola control device 903 is connected to the chain block 203.

[0053] The gondola control device 903 controls the lifting of the under-car gondola 202 by controlling the drive of the chain block 203.

[0054] When the gondola lift button 901 is operated, a gondola lift signal is input from the gondola lift button 901 to the gondola control device 903. By operating the gondola lift button 901, the under-car gondola 202 moves up and down.

[0055] When the car liftable button 902 is operated, a car liftable signal is input from the car liftable button 902 to the elevator control panel 10. Note that the gondola control device 903 may be connected to the elevator control panel 10, and the car liftable button 902 may be connected to the gondola control device 903. In this case, the car liftable signal is input from the car liftable button 902 to the elevator control panel 10 via the gondola control device 903.

[0056] When a car lift signal is input from the car lift button 801 to the elevator control panel 10 and further a car liftable signal is input from the car liftable button 902 to the elevator control panel 10, the elevator control panel 10 moves the car 1 up and down. Therefore, even when a car lift signal is input from the car lift button 801 to the elevator control panel 10, if a car liftable signal is not input from the car liftable button 902 to the elevator control panel 10, the elevator control panel 10 does not move the car 1 up and down. This prevents the car 1 from moving up and down without the consent of the under-car worker 6.

[0057] Next, a procedure for performing maintenance inspection of the landing door device 7 in the elevator apparatus according to Embodiment 1 will be described. First, the car upper worker 5 enters the car upper work space 104, and the car lower worker 6 enters the car lower work space 209.

[0058] After that, the operator 5 above the car operates the car lift buckle 801, and the operator 6 below the car operates the car liftable buckle 902. As a result, the car 1 and the gondola device 2 below the car move up and down together. When the car 1 arrives at a position adjacent to the first landing door device 701 in the working space 104 above the car, the operator 5 above the car stops operating the car lift buckle 801.

[0059] After that, the operator 6 below the car operates the gondola lift buckle 901. As a result, with the car 1 stopped, the gondola 202 below the car moves up and down. When the gondola 202 below the car arrives at a position adjacent to the second landing door device 702 in the working space 209 below the car, the operator 6 below the car stops operating the gondola lift buckle 901.

[0060] After that, the operator 6 below the car connects the lower part of the fixing main wire rope 210 to the gondola 202 below the car. As a result, the downward movement of the gondola 202 below the car relative to the car body 101 is restricted. With the downward movement of the gondola 202 below the car relative to the car body 101 restricted, the operator 5 above the car performs maintenance and inspection on the first landing door device 701, and the operator 6 below the car performs maintenance and inspection on the second landing door device 702.

[0061] When the maintenance and inspection of both the first landing door device 701 and the second landing door device 702 are completed, the operator 5 above the car operates the car lift buckle 801, and the operator 6 below the car operates the car liftable buckle 902, and the car 1 and the gondola device 2 below the car move up and down together. In this case, each of the car 1 and the gondola device 2 below the car moves to the landing on the floor just two floors above. When the maintenance and inspection of all the landing door devices 7 are completed, the maintenance and inspection of the landing door devices 7 in the elevator device are completed.

[0062] As described above, the under-car gondola device 2 according to the first embodiment includes a support device 201 provided on the car 1 and an under-car gondola 202 provided below the car 1 and supported by the support device 201. The support device 201 supports the under-car gondola 202 so that the distance between the car 1 and the under-car gondola 202 can be adjusted. Thereby, both the first boarding door device 701 and the second boarding door device 702 adjacent to each other can be maintained and inspected simultaneously. As a result, the work efficiency when maintaining and inspecting a plurality of boarding door devices 7 can be improved.

[0063] An upper work space 104 for an upper-car worker 5 to enter is formed at the upper part of the car 1, and a lower work space 209 for a lower-car worker 6 to enter is formed in the under-car gondola 202. When the upper work space 104 is adjacent to the first boarding door device 701, the support device 201 supports the under-car gondola 202 so that the lower work space 209 is adjacent to the second boarding door device 702. Thereby, the work efficiency when maintaining and inspecting the first boarding door device 701 and the second boarding door device 702 adjacent to each other can be improved.

[0064] Further, the support device 201 has a chain block 203 connected to the car 1 and supporting the under-car gondola 202. By driving the chain block 203, the distance between the car 1 and the under-car gondola 202 is adjusted. Thereby, the work efficiency when maintaining and inspecting a plurality of boarding door devices 7 can be improved with a simple configuration.

[0065] Further, the support device 201 has a fixing main rope 210 connected to the car 1. By connecting the fixing main rope 210 to the under-car gondola 202, the downward movement of the under-car gondola 202 relative to the car 1 is restricted. Thereby, when the lower-car worker 6 is not operating the gondola lift button 901, the descent of the under-car gondola 202 can be restricted.

[0066] The elevator device according to Embodiment 1 includes a car 1, a support device 201 provided on the car 1, and a car lower gondola 202 provided below the car 1 and supported by the support device 201. The support device 201 supports the car lower gondola 202 so that the distance between the car 1 and the car lower gondola 202 can be adjusted. Thereby, both the first landing door device 701 and the second landing door device 702 adjacent to each other can be simultaneously maintained and inspected. As a result, the working efficiency when maintaining and inspecting a plurality of landing door devices 7 can be improved.

[0067] Further, the elevator device according to Embodiment 1 includes a gondola operation device 9 that is provided on the car lower gondola 202 and is operated by a car lower worker 6 in a car lower work space 209 formed in the car lower gondola 202. The gondola operation device 9 has a gondola lift button 901 that drives the support device 201 when operated. Thereby, the car lower gondola 202 can be lifted and lowered with respect to the car 1 while the car lower worker 6 is in the car lower work space 209.

[0068] Further, the elevator device according to Embodiment 1 includes a car upper operation device 8 that is provided on the car 1 and is operated by a car upper worker 5 in a car upper work space 104 formed above the car 1. The car upper operation device 8 has a car lift button 801 that raises and lowers the car 1 when operated. The gondola operation device 9 has a car liftable button 902 that enables the car 1 to be lifted and lowered when operated. When the car liftable button 902 is operated and the car lift button 801 is operated, the car 1 is lifted and lowered. Thereby, it is possible to prevent the car 1 from being lifted and lowered without the consent of the car lower worker 6 in the car lower work space 209.

[0069] In addition, in Embodiment 1, when a car lift signal is input from the car lift button 801 to the elevator control panel 10, and further, when a car lift enable signal is input from the car lift enable button 902 to the elevator control panel 10, the elevator control panel 10 raises and lowers the car 1. Not limited to this configuration, the under-car gondola device 2 has a detection device that detects whether the positions of a pair of handrail pieces 214 are in the closed position, and the elevator control panel 10 may raise and lower the car 1 based on the detection result of the detection device and the car lift signal of the car lift button 801. Specifically, it may be configured such that when the detection device detects that the positions of a pair of handrail pieces 214 are in the closed position, and further, when a car lift signal is input from the car lift button 801 to the elevator control panel 10, the elevator control panel 10 raises and lowers the car 1. In the case of this configuration, even when a car lift signal is input from the car lift button 801 to the elevator control panel 10, if the detection device does not detect that the positions of a pair of handrail pieces 214 are in the closed position, the elevator control panel 10 does not raise and lower the car 1. Note that in the case of this configuration, the gondola operation device 9 may not have the car lift enable button 902.

[0070] Embodiment 2. FIG. 8 is a front view showing an under-car gondola device of an elevator apparatus according to Embodiment 2. The under-car gondola device 2 has a plurality of main rope guide portions 215 provided on the under-car gondola 202.

[0071] The number of the main rope guide portions 215 is four. Two of the four main rope guide portions 215 are provided at one end in the width direction of the under-car gondola 202, and the remaining two main rope guide portions 215 are provided at the other end in the width direction of the under-car gondola 202. The width direction of the under-car gondola 202 is the same direction as the width direction of the car body 101.

[0072] Of the two main wire guides 215 provided at one end in the width direction of the under-car gondola 202, one main wire guide 215 is provided above the under-car gondola 202, and the remaining one main wire guide 215 is provided below the under-car gondola 202. Each of the two main wire guides 215 provided at one end in the width direction of the under-car gondola 202 is guided by the same fixing main wire 210.

[0073] Of the two main wire guides 215 provided at the other end in the width direction of the under-car gondola 202, one main wire guide 215 is provided above the under-car gondola 202, and the remaining one main wire guide 215 is provided below the under-car gondola 202. Each of the two main wire guides 215 provided at the other end in the width direction of the under-car gondola 202 is guided by the same fixing main wire 210.

[0074] By guiding each main wire guide 215 by the fixing main wire 210, the under-car gondola 202 is guided by the fixing main wire 210.

[0075] The fixing main wire 210 has a main wire body 216 and a spherical portion 217 provided below the main wire body 216. By providing the spherical portion 217 below the main wire body 216, the main wire body 216 is arranged to extend in the vertical direction.

[0076] FIG. 9 is a plan view showing the main wire guide portion 215 and the fixing main wire 210 of FIG. 8. A through hole 218 extending in the vertical direction is formed in the main wire guide portion 215. The cross-sectional shape along the horizontal plane on the inner wall surface of the through hole 218 is circular.

[0077] The diameter of the inner wall surface of the through hole 218 is larger than the diameter of the main wire body 216. Therefore, the main wire body 216 can pass through the through hole 218. On the other hand, the diameter of the inner wall surface of the through hole 218 is smaller than the diameter of the spherical portion 217. Therefore, the spherical portion 217 cannot pass through the through hole 218.

[0078] As shown in FIG. 8, the spherical portion 217 is disposed below the main rope guide portion 215. When the chain block 203 is driven, the lower gondola 202 moves up and down with respect to the gondola body 101. When the main rope guide portion 215 hits the spherical portion 217 from above, the downward movement of the lower gondola 202 with respect to the gondola body 101 is restricted. Other configurations are the same as those in the first embodiment.

[0079] As described above, the lower gondola device 2 according to the second embodiment includes the fixing main rope 210 and the main rope guide portion 215 provided on the lower gondola 202. The fixing main rope 210 includes a main rope body 216 suspended from the cage 1 and a spherical portion 217 provided at the lower portion of the main rope body 216. A through hole 218 is formed in the main rope guide portion 215, and the diameter of the inner wall surface of the through hole 218 is larger than the diameter of the main rope body 216 and smaller than the diameter of the spherical portion 217. The spherical portion 217 is disposed below the main rope guide portion 215. Thereby, the downward movement of the lower gondola 202 with respect to the cage 1 beyond a preset range can be restricted.

[0080] In the second embodiment, similar to the first embodiment, the lower gondola 202 has the guide device 208. However, since the lower gondola 202 has the main rope guide portion 215, a configuration without the guide device 208 may be used.
