[0010] The embodiments for carrying out the subject of the present disclosure will be described with reference to the attached drawings. In each drawing, the same or corresponding parts are given the same reference numerals, and duplicated descriptions are appropriately simplified or omitted. Note that the subject of the present disclosure is not limited to the following embodiments, and any component of the embodiment may be modified or omitted within the scope of the gist of the present disclosure.

[0011] Embodiment 1 Fig. 1 is a configuration diagram showing an elevator according to embodiment 1. In the figure, the elevator has a first elevator 1 and a second elevator 2. The first elevator 1 and the second elevator 2 are provided adjacent to each other.

[0012] The first elevator 1 has a car 11, a counterweight 12, a hoist 13, a deflector sheave 14, and a number of suspension bodies 15. The second elevator 2 has a car 21, a counterweight 22, a hoist 23, a deflector sheave 24, and a number of suspension bodies 25.

[0013] A machine room 4 is provided above the hoistway 3. A car 11 and a counterweight 12 of the first elevator 1, and a car 21 and a counterweight 22 of the second elevator 2 are provided in the hoistway 3. A hoist 13 and a deflection sheave 14 of the first elevator 1, and a hoist 23 and a deflection sheave 24 of the second elevator 2 are provided in the machine room 4.

[0014] In the first elevator 1, the hoist 13 generates a driving force for moving the car 11 and the counterweight 12. The hoist 13 has a driving sheave 13a. The driving sheave 13a is rotated by the driving force of the hoist 13.

[0015] In the first elevator 1, a plurality of suspension bodies 15 are wound around the driving sheave 13a and the deflector sheave 14. The suspension bodies 15 are made of ropes, belts, or the like. One end of each suspension body 15 is connected to the car 11, and the other end of each suspension body 15 is connected to the counterweight 12. As a result, in the first elevator 1, the car 11 and the counterweight 12 are suspended in the hoistway 3 by each suspension body 15. In the first elevator 1, the driving sheave 13a rotates, causing the car 11 and the counterweight 12 to move up and down in the hoistway 3.

[0016] In the second elevator 2, the hoist 23 generates a driving force for moving the car 21 and the counterweight 22. The hoist 23 has a driving sheave 23a. The driving sheave 23a is rotated by the driving force of the hoist 23.

[0017] In the second elevator 2, a plurality of suspension bodies 25 are wound around the driving sheave 23a and the deflector sheave 24. A rope, a belt, or the like is used as the suspension bodies 25. One end of each suspension body 25 is connected to the car 21, and the other end of each suspension body 25 is connected to the counterweight 22. As a result, in the second elevator 2, the car 21 and the counterweight 22 are suspended in the hoistway 3 by each suspension body 25. In the second elevator 2, the driving sheave 23a rotates, causing the car 21 and the counterweight 22 to move up and down in the hoistway 3.

[0018] The car 11 of the first elevator 1 moves along a first path set up in the vertical direction in the hoistway 3. The car 21 of the second elevator 2 moves along a second path set up in the vertical direction in the hoistway 3. The first path and the second path are two paths set in the same hoistway 3. In addition, the first path and the second path are adjacent to each other in the width direction of the hoistway 3. As a result, when the car 11 and the car 21 stop at the same height, the positions of the car 11 and the car 21 are adjacent to each other.

[0019] Fig. 2 is a perspective view showing the car 11 of the first elevator unit 1 in Fig. 1. Fig. 3 is a perspective view showing the car 21 of the second elevator unit 2 in Fig. 1. Each of the car 11 and the car 21 has a car body 5, a car frame 6, and a plurality of diagonal brace members 7. Each of the car 11 and the car 21 is arranged such that the height direction of the car body 5 coincides with the vertical direction.

[0020] In each of the cars 11 and 21, a specific direction perpendicular to the height direction of the car body 5 is the depth direction of the car body 5. In addition, in each of the cars 11 and 21, a direction perpendicular to both the height direction and the depth direction of the car body 5 is the width direction of the car body 5. Each of the cars 11 and 21 is disposed in the hoistway 3 with the width direction of the car body 5 coinciding with the width direction of the hoistway 3.

[0021] The car body 5 has a car floor 51, a car ceiling 52, a car front wall 53, a car rear wall 54, a first car side wall 55, and a second car side wall 56. The space inside the car body 5 is surrounded by the car floor 51, the car ceiling 52, the car front wall 53, the car rear wall 54, the first car side wall 55, and the second car side wall 56.

[0022] The car ceiling 52 is located above the car floor 51. The car front wall 53 and the car rear wall 54 face each other in the depth direction of the car body 5. The first car side wall 55 and the second car side wall 56 face each other in the width direction of the car body 5.

[0023] In each of the cage 11 and cage 21, when the cage front wall 53 is viewed from outside the cage body 5 along the depth direction of the cage body 5, the first cage side wall 55 is located on the right side of the cage front wall 53, and the second cage side wall 56 is located on the left side of the cage front wall 53. When the cage 11 and cage 21 are positioned adjacent to each other, the first cage side wall 55 of the cage 11 and the second cage side wall 56 of the cage 21 face each other.

[0024] The car frame 6 supports the car body 5. The car frame 6 has a floor frame 61, an upper frame 62, and a pair of vertical frames 63.

[0025] The car body 5 is placed on the floor frame 61. As a result, the floor frame 61 supports the car body 5 from below. In this embodiment, the floor frame 61 has a rectangular shape that follows the outer periphery of the car floor 51.

[0026] The upper frame 62 is located above the car body 5. The upper frame 62 is disposed along the width direction of the car body 5. One end of each suspension body 15 of the first elevator unit 1 is connected to the upper frame 62 of the car 11. One end of each suspension body 25 of the second elevator unit 2 is connected to the upper frame 62 of the car 21.

[0027] The pair of vertical frames 63 are disposed on both sides in the width direction of the car body 5. That is, the car body 5 is disposed between the pair of vertical frames 63 in the width direction of the car body 5. Of the pair of vertical frames 63, one vertical frame 63 faces the first car side wall 55, and the other vertical frame 63 faces the second car side wall 56.

[0028] Each vertical frame 63 is disposed along the height direction of the car body 5. The lower end of each vertical frame 63 is fixed to the floor frame 61. The upper end of each vertical frame 63 is fixed to the upper frame 62. As a result, each vertical frame 63 connects the floor frame 61 and the upper frame 62.

[0029] The multiple diagonal bracing members 7 are attached to the car frame 6. The multiple diagonal bracing members 7 are connected to the floor frame 61 from a pair of vertical frames 63 on the outside of the car body 5. In this way, each diagonal bracing member 7 reinforces the car frame 6. In this embodiment, four diagonal bracing members 7 are attached to the car frame 6. In this embodiment, one vertical frame 63 is connected to the floor frame 61 via two diagonal bracing members 7, and the other vertical frame 63 is connected to the floor frame 61 via the remaining two diagonal bracing members 7.

[0030] Two upper diagonal brace mounting portions 65 are provided at the middle portion of each vertical frame 63. Thus, four upper diagonal brace mounting portions 65 are provided on the car frame 6. The four upper diagonal brace mounting portions 65 correspond to the four diagonal brace members 7, respectively. Each diagonal brace member 7 is attached to the vertical frame 63 via the corresponding upper diagonal brace mounting portion 65.

[0031] Four lower diagonal brace mounting parts 66 are provided on the outer periphery of the floor frame 61. The position of each lower diagonal brace mounting part 66 is lower than the position of each upper diagonal brace mounting part 65. The four lower diagonal brace mounting parts 66 are provided at the four corners of the floor frame 61. As a result, of the four lower diagonal brace mounting parts 66, two lower diagonal brace mounting parts 66 are located closer to the car front wall 53 than the vertical frames 63, and the remaining two lower diagonal brace mounting parts 66 are located closer to the car rear wall 54 than the vertical frames 63.

[0032] The four lower diagonal brace mounting portions 66 correspond to the four diagonal brace members 7, respectively. Each diagonal brace member 7 is attached to the floor frame 61 via the corresponding lower diagonal brace mounting portion 66. As a result, each diagonal brace member 7 is disposed at an angle relative to the vertical frame 63 and the floor frame 61.

[0033] The car main body 5 is provided with a car entrance 57 and a rescue opening 58. The car entrance 57 can be opened and closed by a pair of car doors (not shown). The rescue opening 58 can be opened and closed by a rescue door (not shown).

[0034] During normal operation of the first elevator 1, with the car 11 stopped at each floor, passengers can get on and off the car body 5 of the car 11 through the car entrance / exit 57 of the car 11. During normal operation of the second elevator 2, with the car 21 stopped at each floor, passengers can get on and off the car body 5 of the car 21 through the car entrance / exit 57 of the car 21.

[0035] In the car 11 of the first elevator unit 1, as shown in Fig. 2, the car entrance 57 is provided in the car front wall 53, and the rescue exit 58 is provided in the first car side wall 55. As a result, in the car 11, the rescue exit 58 is located at a position different from the car entrance 57. In the car 11, the rescue exit 58 is provided in the first car side wall 55 to avoid a position facing the vertical frame 63. In this embodiment, in the car 11, the rescue exit 58 is provided at a position closer to the car rear wall 54 than the vertical frame 63.

[0036] On the other hand, in the car 21 of the second elevator unit 2, as shown in Fig. 3, the car entrance 57 is provided in the car front wall 53, and the rescue exit 58 is provided in the second car side wall 56. As a result, in the car 21 as well, the rescue exit 58 is located at a position different from the car entrance 57. In the car 21, the rescue exit 58 is provided in the second car side wall 56 to avoid a position facing the vertical frame 63. In this embodiment, in the car 21, the rescue exit 58 is provided at a position closer to the car rear wall 54 than the vertical frame 63.

[0037] In each of the cars 11 and 21, of the four diagonal bracing members 7, three are normal diagonal bracing members 7A, and one is a connecting diagonal bracing member 7B. In each of the cars 11 and 21, the normal diagonal bracing members 7A are arranged so as to avoid positions facing the car entrance 57 and the rescue exit 58. In contrast, in each of the cars 11 and 21, the connecting diagonal bracing member 7B is arranged at a position facing the rescue exit 58.

[0038] Therefore, in the car 11, as shown in Fig. 2, of the two diagonal braces 7 located on the first car side wall 55 side of the car body 5, the diagonal brace 7 located closer to the car rear wall 54 is the connecting diagonal brace 7B. Also, in the car 21, as shown in Fig. 3, of the two diagonal braces 7 located on the second car side wall 56 side of the car body 5, the diagonal brace 7 located closer to the car rear wall 54 is the connecting diagonal brace 7B.

[0039] Fig. 4 is a side view showing the car 11 of Fig. 2. Fig. 5 is a side view showing the car 21 of Fig. 3. Fig. 4 shows the car 11 as viewed from the first car side wall 55 side of the car 11. Fig. 5 shows the car 21 as viewed from the second car side wall 56 side of the car 21. In each of the cars 11 and 21, the car body 5 is placed on the floor frame 61 via a plurality of vibration isolation devices 8 provided at the four corners of the floor frame 61. As a result, in each of the cars 11 and 21, the transmission of vibration from the car frame 6 to the car body 5 is suppressed.

[0040] Each normal brace member 7A has a main body portion 71 and a rod-shaped portion 72.

[0041] The main body 71 is a band-shaped portion disposed along the longitudinal direction of the normal diagonal brace member 7A. One end of the main body 71 is attached to the vertical frame 63 via the upper diagonal brace attachment portion 65. A rod-shaped portion 72 is fixed to the other end of the main body 71.

[0042] The rod-shaped portion 72 protrudes in the longitudinal direction of the normal diagonal brace member 7A from the other end of the main body portion 71. The rod-shaped portion 72 is attached to the floor frame 61 via the lower diagonal brace mounting portion 66. At least a portion of the rod-shaped portion 72 is a threaded portion.

[0043] On the other hand, the connecting brace member 7B has a first reinforcing portion 73 and a second reinforcing portion 74.

[0044] The first reinforcing portion 73 is a strip-shaped portion along the longitudinal direction of the connecting diagonal brace member 7B. One end of the first reinforcing portion 73 is attached to the vertical frame 63 via the upper diagonal brace attachment portion 65. The other end of the first reinforcing portion 73 is connected to the second reinforcing portion 74.

[0045] The second reinforcing portion 74 is disposed along the longitudinal direction of the connecting brace member 7B. The length of the second reinforcing portion 74 is shorter than the length of the first reinforcing portion 73. The second reinforcing portion 74 has a plate-shaped portion 741 and a rod-shaped portion 742.

[0046] The plate-shaped portion 741 has a strip-like shape along the longitudinal direction of the connecting brace member 7B. One end of the plate-shaped portion 741 is connected to the other end of the first reinforcing portion 73. The rod-shaped portion 742 is fixed to the other end of the plate-shaped portion 741.

[0047] The rod-shaped portion 742 protrudes from the other end of the plate-shaped portion 741 in the longitudinal direction of the connecting diagonal brace member 7B. The rod-shaped portion 742 is attached to the floor frame 61 via the lower diagonal brace mounting portion 66. At least a portion of the rod-shaped portion 742 is a threaded portion. The shape of the rod-shaped portion 742 in the connecting diagonal brace member 7B is the same as the shape of the rod-shaped portion 72 in the normal diagonal brace member 7A.

[0048] Each upper diagonal brace mounting portion 65 has a mounting axis 651. In each upper diagonal brace mounting portion 65, the mounting axis 651 is disposed along the width direction of the car body 5. The main body portion 71 of each normal diagonal brace member 7A is attached to the vertical frame 63 so as to be rotatable about the mounting axis 651 of the corresponding upper diagonal brace mounting portion 65. The first reinforcing portion 73 of the connecting diagonal brace member 7B is attached to the vertical frame 63 so as to be rotatable about the mounting axis 651 of the corresponding upper diagonal brace mounting portion 65.

[0049] Each lower diagonal brace mounting portion 66 has a socket 661 and a nut 662. A through hole is provided in the socket 661. The socket 661 is fixed to the floor frame 61 with the through hole inclined relative to the horizontal plane.

[0050] The rod-shaped portion 72 of each normal diagonal brace member 7A is inserted into the through hole of the socket 661 of the corresponding lower diagonal brace mounting portion 66. The nut 662 is screwed onto the rod-shaped portion 72 inserted into the through hole of the socket 661. In each normal diagonal brace member 7A, the nut 662 screwed onto the rod-shaped portion 72 engages with the socket 661, thereby preventing the rod-shaped portion 72 from coming out of the socket 661. Each normal diagonal brace member 7A is attached to the floor frame 61 by tightening the nut 662 onto the rod-shaped portion 72.

[0051] The rod-shaped portion 742 of the connecting brace member 7B is inserted into the through hole of the socket 661 of the corresponding lower brace mounting portion 66. The nut 662 is screwed onto the rod-shaped portion 742 inserted into the through hole of the socket 661. In the connecting brace member 7B, the nut 662 screwed onto the rod-shaped portion 742 engages with the socket 661, thereby preventing the rod-shaped portion 742 from coming out of the socket 661. The second reinforcing portion 74 of the connecting brace member 7B is attached to the floor frame 61 by tightening the nut 662 onto the rod-shaped portion 742.

[0052] The other end of the first reinforcing part 73 is detachably connected to the plate-shaped part 741 of the second reinforcing part 74 by a thumbscrew 75 serving as a fastener. In the connecting brace member 7B, the first reinforcing part 73 is separated from the second reinforcing part 74 by removing the thumbscrew 75.

[0053] Fig. 6 is a side view showing a state in which the first reinforcing part 73 is separated from the second reinforcing part 74 in the car 11 of Fig. 4. Fig. 7 is a side view showing a state in which the first reinforcing part 73 is separated from the second reinforcing part 74 in the car 21 of Fig. 5. In each of the cars 11 and 21, when the first reinforcing part 73 is separated from the second reinforcing part 74, the first reinforcing part 73 is suspended from the mounting shaft 651 of the upper diagonal brace mounting part 65 due to its own weight. As a result, the first reinforcing part 73 is arranged along the vertical frame 63, and the first reinforcing part 73 is removed from the position facing the rescue exit 58.

[0054] Fig. 8 is an exploded perspective view showing a connecting portion between the first reinforcing portion 73 and the second reinforcing portion 74 in the connecting brace member 7B in Fig. 4. A long hole 76 is provided in the plate-shaped portion 741 of the second reinforcing portion 74 along the longitudinal direction of the second reinforcing portion 74. The long hole 76 penetrates the plate-shaped portion 741 in the thickness direction of the plate-shaped portion 741.

[0055] The first reinforcing portion 73 is provided with a protrusion 77. The protrusion 77 protrudes from the first reinforcing portion 73 in the thickness direction of the first reinforcing portion 73. The protrusion 77 has a pair of side surfaces formed along the longitudinal direction of the first reinforcing portion 73. In this embodiment, the shape of the protrusion 77 is a rectangular parallelepiped.

[0056] The protrusion 77 is inserted into the long hole 76. When the protrusion 77 is inserted into the long hole 76, the longitudinal direction of each of the first reinforcing part 73 and the second reinforcing part 74 coincides with the longitudinal direction of the connecting brace member 7B. When the protrusion 77 is inserted into the long hole 76, a pair of side surfaces of the protrusion 77 contact the inner surface of the long hole 76, thereby preventing the first reinforcing part 73 from rotating relative to the second reinforcing part 74. When the protrusion 77 is inserted into the long hole 76, the protrusion 77 can slide through the long hole 76 in the longitudinal direction of the connecting brace member 7B. Thus, the long hole 76 serves as a guide hole that guides the protrusion 77.

[0057] A screw hole 78 is provided in the protrusion 77. The depth direction of the screw hole 78 coincides with the thickness direction of the first reinforcing portion 73. The thumbscrew 75 is screwed into the screw hole 78 of the protrusion 77. In this way, the thumbscrew 75 is attached to the protrusion 77. A flat washer 79 is interposed between the thumbscrew 75 and the plate-shaped portion 741.

[0058] The thumbscrew 75 is attached to a protrusion 77 inserted into the long hole 76 and tightened, thereby fastening the first reinforcing portion 73 to the plate-shaped portion 741 of the second reinforcing portion 74. That is, the first reinforcing portion 73 is fastened to the second reinforcing portion 74 by the thumbscrew 75 attached to the protrusion 77.

[0059] In the connecting brace member 7B, the first reinforcing part 73 is separated from the second reinforcing part 74 by removing the thumbscrew 75 from the protrusion 77. This makes it possible to manually separate the first reinforcing part 73 and the second reinforcing part 74 in the connecting brace member 7B without using tools. The configuration of the connecting brace member 7B is the same for both the car 11 and the car 21.

[0060] Next, the operation will be described. During normal operation of the elevator, the car 11 moves along a first path of the hoistway 3, and the car 21 moves along a second path of the hoistway 3. The movement of the car 11 is controlled by a control device (not shown) in the first elevator 1. The movement of the car 21 is controlled by a control device (not shown) in the second elevator 2. As a result, the movements of the car 11 and the car 21 are controlled independently of each other.

[0061] If the car 11 suddenly stops due to an abnormality in the first elevator unit 1 while the car 11 is descending, the floor frame 61 of the car 11 receives a downward inertial force from the car body 5 via each vibration isolation device 8. This causes the floor frame 61 of the car 11 to bend downward at the positions of each vibration isolation device 8. At this time, the support of each diagonal brace member 7 in the car 11 suppresses an increase in the amount of bending of the floor frame 61.

[0062] In the connecting brace member 7B of the car 11, as the floor frame 61 flexes, the protrusion 77 slides through the long hole 76 in the direction in which the length of the connecting brace member 7B increases. As a result, the protrusion 77 engages with the second reinforcing portion 74 at the end of the long hole 76. As a result, in the car 11, tension is applied not only to each normal brace member 7A but also to the connecting brace member 7B, suppressing an increase in the amount of flexure of the floor frame 61.

[0063] Also, if the car 21 suddenly stops due to an abnormality in the second elevator unit 2 while the car 21 is descending, an increase in the amount of deflection of the floor frame 61 of the car 21 is suppressed by the support of the diagonal braces 7, as in the case of the car 11. At this time, in the connecting diagonal brace members 7B of the car 21, the protrusions 77 that have slid through the long holes 76 engage with the second reinforcing parts 74, as in the connecting diagonal brace members 7B of the car 11. As a result, when the car 21 suddenly stops, tension is applied not only to the normal diagonal brace members 7A of the car 21 but also to the connecting diagonal brace members 7B of the car 21, suppressing an increase in the amount of deflection of the floor frame 61 of the car 21.

[0064] If a passenger is trapped in one of the cages 11 and 21, that cage becomes an abnormal cage that cannot move through the hoistway 3. In contrast, the other cage is a normal cage that can move through the hoistway 3. Therefore, if a passenger is trapped in one of the cages 11 and 21, the other cage, which is a normal cage, is used to rescue the passenger trapped in the one cage, which is an abnormal cage.

[0065] For example, if car 11 carrying passengers stops due to an abnormality in first elevator unit 1, car 11 cannot move and passengers are trapped in car 11. Therefore, if passengers are trapped in car 11, car 21, which is a normal car, is used to rescue the passengers trapped in car 11, which is an abnormal car.

[0066] Next, an elevator passenger rescue method for rescuing passengers from the car 11 when they are trapped in the car 11 will be described. Fig. 9 is a flowchart showing the elevator passenger rescue method according to the first embodiment. The elevator passenger rescue method includes a car moving step S1, a rescue door opening step S2, a diagonal brace operating step S3, and a passenger moving step S4.

[0067] <Basket movement process S1> When a passenger becomes trapped in the car 11 due to some abnormality and the car 11 becomes an abnormal car, a car movement process S1 is carried out to move the car 21. The car 21 is a normal car that can move in the elevator 3. In the car movement process S1, the car 21 is moved to a position adjacent to the car 11. That is, in the car movement process S1, the car 21 is moved to the same height as the height of the stopping position of the car 11. At this time, the car 21 is moved by manual operation by a rescuer. Also, at this time, the rescuer is put on the car 21 and the car 21 is moved. When the car 21 stops at a position adjacent to the car 11, the rescue exits 58 of the car 11 and the car 21 face each other.

[0068] <Rescue opening process S2> After the car moving step S1, a rescue exit opening step S2 is carried out to open the rescue exits 58 of each of the cars 11 and 21. In the rescue exit opening step S2, the rescue doors of each of the cars 11 and 21 are moved to open the rescue exits 58. At this time, in the car 11, a passenger in the car body 5 of the car 11 opens the rescue exit 58 of the car 11. Also, in the car 21, a rescuer in the car body 5 of the car 21 opens the rescue exit 58 of the car 21.

[0069] <Brace operation process S3> After the rescue door opening step S2, a brace operation step S3 is carried out to separate the first reinforcement part 73 from the second reinforcement part 74 in the connecting brace members 7B of each of the cars 11 and 21. In the brace operation step S3, the thumbscrews 75 of the connecting brace members 7B are removed from the protrusions 77 to separate the first reinforcement part 73 from the second reinforcement part 74 in each of the cars 11 and 21. At this time, in the car 11, a passenger in the car body 5 of the car 11 separates the first reinforcement part 73 of the car 11 from the second reinforcement part 74. Also, in the car 21, a rescuer in the car body 5 of the car 21 separates the first reinforcement part 73 of the car 21 from the second reinforcement part 74.

[0070] Here, when each of the cars 11 and 21 is stopped in the elevator shaft 3, no downward inertial force is applied from the car body 5 to the floor frame 61, so the tension applied to each of the connecting brace members 7B of the cars 11 and 21 is weakened. Therefore, in the brace operation step S3, in each of the connecting brace members 7B of the cars 11 and 21, the thumbscrews 75 are easily removed, and the first reinforcing portion 73 is easily separated from the second reinforcing portion 74.

[0071] In the diagonal brace operating step S3, when the first reinforcing part 73 is separated from the second reinforcing part 74, the first reinforcing part 73 hangs down from the mounting shaft 651 of the upper diagonal brace mounting part 65 by its own weight. As a result, the first reinforcing parts 73 of the cars 11 and 21 move to positions away from the positions facing the rescue exits 58 of the cars 11 and 21.

[0072] <Passenger movement process S4> After the brace operation process S3, a passenger movement process S4 is carried out in which passengers in the car body 5 of the car 11 move into the car body 5 of the car 21. In the passenger movement process S4, passengers move from inside the car body 5 of the car 11 into the car body 5 of the car 21 through the rescue exit 58 of the car 11 and the rescue exit 58 of the car 21. At this time, since the first reinforcing parts 73 of each connecting brace member 7B are disengaged from the positions facing the rescue exits 58 of the car 11 and the car 21, the first reinforcing parts 73 of each connecting brace member 7B do not interfere with the movement of passengers. Therefore, in the passenger movement process S4, passengers can easily move from the car 11 to the car 21.

[0073] After the passenger moving process S4, the car 21 carrying the passengers moves to the nearest floor, thereby completing the rescue of the passengers.

[0074] When a passenger is trapped in the car 21 and the car 21 becomes an abnormal car, the car 11 is used as a normal car to rescue the passenger trapped in the car 21. That is, the operation of the car 11 and the operation of the car 21 are switched between when the car 11 becomes an abnormal car and when the car 21 becomes an abnormal car. Even when a passenger is trapped in the car 21 and the car 21 becomes an abnormal car, each process is performed in the order of the car moving process S1, the rescue door opening process S2, the diagonal brace operating process S3, and the passenger moving process S4. This completes the movement of the passenger from inside the car body 5 of the car 21 to inside the car body 5 of the car 11. After the passenger moving process S4, the normal car 11 with the passengers on board moves to the nearest floor, completing the rescue of the passengers.

[0075] In the car 11 and the car 21 of such an elevator, a connecting brace member 7B is arranged at a position facing the rescue exit 58 on the outside of the car body 5. In the connecting brace member 7B, a first reinforcing part 73 attached to the vertical frame 63 of the car frame 6 is detachably connected to a second reinforcing part 74 attached to the floor frame 61 of the car frame 6. Therefore, the car frame 6 can be reinforced by the connecting brace member 7B, and the strength of the car frame 6 itself can be reduced. This allows the size of the members constituting the car frame 6 to be reduced, and the weight of the car frame 6 can be reduced. Therefore, the size of each of the hoisting machines 13 and 23 can be reduced, and the cost of the entire elevator can be reduced.

[0076] Also, the first reinforcing portion 73 can be separated from the second reinforcing portion 74. Therefore, the first reinforcing portion 73 can be removed from the position facing the rescue exit 58. This prevents the first reinforcing portion 73 from getting in the way when passengers trapped in the car 11 or 21 are rescued through the rescue exit 58. Therefore, passengers can be efficiently rescued from the car 11 or 21.

[0077] In addition, in the connecting brace member 7B, the second reinforcing part 74 is provided with an elongated hole 76, and the first reinforcing part 73 is provided with a protrusion 77. When the protrusion 77 is inserted into the elongated hole 76, the protrusion 77 can slide through the elongated hole 76 in the longitudinal direction of the connecting brace member 7B. The first reinforcing part 73 is fastened to the second reinforcing part 74 by a thumbscrew 75 attached to the protrusion 77. Therefore, the first reinforcing part 73 can be detachably connected to the second reinforcing part 74 with a simple configuration. In addition, when the car 11 and the car 21 are stopped, the magnitude of the tension applied to the connecting brace member 7B can be reduced. This makes it easier to separate the first reinforcing part 73 from the second reinforcing part 74. Therefore, passengers can be rescued from the car 11 or the car 21 more efficiently.

[0078] Moreover, the fastener for fastening the first reinforcing portion 73 to the second reinforcing portion 74 is a thumbscrew 75. Therefore, the thumbscrew 75 can be removed from the protrusion 77 without using a tool, making it even easier to separate the first reinforcing portion 73 from the second reinforcing portion 74.

[0079] In addition, such an elevator passenger rescue method includes a car moving step S1, a rescue door opening step S2, and a diagonal brace operation step S3. In the car moving step S1, when one of the cars 11 and 21 becomes an abnormal car, the other car, which is a normal car, is moved to a position adjacent to the abnormal car. In the rescue door opening step S2, the rescue doors 58 of the abnormal car and the normal car are opened. In the diagonal brace operation step S3, the first reinforcement part 73 is separated from the second reinforcement part 74 in the connecting diagonal brace member 7B of the abnormal car and the normal car. Therefore, when passengers are rescued from the abnormal car to the normal car through the rescue doors 58 of the cars 11 and 21, the connecting diagonal brace member 7B of the cars 11 and 21 can be prevented from getting in the way. This allows passengers to be rescued efficiently from the car 11 or 21. Furthermore, by reinforcing the car frame 6 with the connecting brace members 7B, the weight of the car frame 6 can also be reduced.

[0080] In the above embodiment, the second reinforcing part 74 may be rotatable with respect to the floor frame 61 in each of the car 11 and the car 21. In this case, the socket 661 into which the rod-shaped part 742 of the second reinforcing part 74 is inserted is provided on the floor frame 61 so as to be rotatable about a mounting axis along the width direction of the car main body 5. In this way, when the first reinforcing part 73 is separated from the second reinforcing part 74, the second reinforcing part 74 can be removed from the position facing the rescue opening 58.

[0081] Furthermore, in the above embodiment, the length of the second reinforcement portion 74 is shorter than the length of the first reinforcement portion 73 in each of the cages 11 and 21. However, the length of the second reinforcement portion 74 may be longer than the length of the first reinforcement portion 73, or the length of the second reinforcement portion 74 may be the same as the length of the first reinforcement portion 73. Even in this manner, by separating the first reinforcement portion 73 from the second reinforcement portion 74, at least one of the first reinforcement portion 73 and the second reinforcement portion 74 can be removed from the position facing the rescue opening 58.

[0082] In the above embodiment, the long hole 76 is provided in the second reinforcing portion 74, and the protrusion 77 is provided in the first reinforcing portion 73. However, the long hole 76 may be provided in the first reinforcing portion 73, and the protrusion 77 may be provided in the second reinforcing portion 74. In this case, the long hole 76 is provided in the first reinforcing portion 73 along the length direction of the first reinforcing portion 73. Even in this case, the first reinforcing portion 73 can be detachably connected to the second reinforcing portion 74. Also, in this case, the long hole 76 may be a round hole. Even in this case, the amount of deflection of the floor frame 61 can be suppressed by the support of the connecting brace member 7B when the floor frame 61 is deflected.

[0083] In the above embodiment, the long hole 76 is provided in the second reinforcing portion 74. However, the long hole 76 may be a round hole. Even in this case, when the floor frame 61 is bent, the amount of bending of the floor frame 61 can be suppressed by the support of the connecting brace member 7B.

[0084] In the above embodiment, the fastener for fastening the first reinforcing portion 73 to the second reinforcing portion 74 is the thumbscrew 75. However, the fastener for fastening the first reinforcing portion 73 to the second reinforcing portion 74 does not have to be the thumbscrew 75. As long as the fastener can be removed from the protrusion 77 without using a tool, for example, a hexagonal bolt may be used as the fastener for fastening the first reinforcing portion 73 to the second reinforcing portion 74.

[0085] The configurations shown in the above embodiments are examples of the contents of the present disclosure. The embodiments can be combined with other known technologies. A part of the configuration of the embodiments can be omitted or modified without departing from the gist of the present disclosure. [Explanation of symbols]
