[0018] The embodiments will now be described with reference to the accompanying drawings.

[0019] Implementation method 1.

[0020] Figure 1 This is a schematic structural diagram of the elevator according to Embodiment 1. In the diagram, a machine room 2 is provided above the hoistway 1. The machine room 2 is equipped with a traction machine 3, a deflector sheave 4, and an elevator control device 5.

[0021] The traction machine 3 includes a drive sheave 6, a traction machine motor (not shown), and a traction mechanism brake (not shown). The traction machine motor rotates the drive sheave 6. The traction mechanism brake keeps the drive sheave 6 stationary. Additionally, the traction mechanism brakes the rotation of the drive sheave 6.

[0022] A suspension body 7 is wound around the drive sheave 6 and the deflector sheave 4. Multiple ropes or belts are used as the suspension body 7. A car assembly 8 is connected to the first end of the suspension body 7. A counterweight 9 is connected to the second end of the suspension body 7.

[0023] The car assembly 8 and counterweight 9 are suspended by the suspension body 7 and move up and down within the hoistway 1 by rotating the drive sheave 6. The elevator control unit 5 controls the operation of the car assembly 8 by controlling the traction machine 3.

[0024] A pair of car guide rails (not shown) and a pair of counterweight guide rails (not shown) are installed in the hoistway 1. The pair of car guide rails guide the lifting and lowering of the car device 8. The pair of counterweight guide rails guide the lifting and lowering of the counterweight 9.

[0025] The car assembly 8 includes a car frame 10, a car compartment 11, and a pair of car doors 12. A suspension body 7 is connected to the car frame 10. The car compartment 11 is supported by the car frame 10. A car entrance / exit is provided in the car compartment 11. The pair of car doors 12 open and close the car entrance / exit.

[0026] A door controller 13 is provided on the car unit 8. The door controller 13 controls the opening and closing of the car door 12.

[0027] Each of the multi-level stations is equipped with a pair of landing doors 14. At each station, the pair of landing doors 14 open and close the station entrance / exit. In addition, at each station, the pair of landing doors 14 open and close in conjunction with a pair of car doors 12 when the car unit 8 arrives.

[0028] Figure 2 It means Figure 1 Side view of the car unit 8. Figure 3 It means Figure 2 A top view of the car unit 8.

[0029] Although Figure 1 The details are omitted, but the car assembly 8 also includes multiple vibration damping components 15, a door support frame 16, a pair of connecting arms 17, and multiple rollers 18.

[0030] The car frame 10 has a floor frame 21, a pair of longitudinal columns 22 which are longitudinal components, and a top beam (not shown). The pair of longitudinal columns 22 are erected vertically on the floor frame 21. The top beam is horizontally supported between the upper ends of the pair of longitudinal columns 22.

[0031] The car compartment 11 is positioned between a pair of longitudinal columns 22. Additionally, the car compartment 11 has a flat car floor 23 and a car compartment body 24. The car floor 23 is supported on a floor frame 21. The car compartment body 24 is mounted on the car floor 23. The car entrance / exit is located on the front surface of the car compartment body 24.

[0032] Multiple vibration damping components 15 are located between the floor frame 21 and the car floor 23. The material used for each vibration damping component 15 is, for example, rubber. The multiple vibration damping components 15 suppress the transmission of vibration from the car frame 10 to the car compartment 11 when the car unit 8 is in motion. Furthermore, the multiple vibration damping components 15 suppress vibrations in the car compartment 11 caused by users entering and exiting the car compartment 11.

[0033] The door support frame 16 has a pair of corner posts 25 and a crossbeam 26. The pair of corner posts 25 stand vertically on the car floor 23, spaced apart from each other in the width direction of the car compartment 11. The width direction of the car compartment 11 is parallel to the opening and closing direction of the pair of car doors 12. Figure 3 The up and down directions.

[0034] A crossbeam 26 is horizontally mounted between the upper ends of a pair of corner posts 25. That is, the crossbeam 26 is supported on the car floor 23 by a pair of corner posts 25. The crossbeam 26 is located above the car entrance / exit.

[0035] A pair of car doors 12 are suspended from a crossbeam 26. A car door track (not shown) is provided on the crossbeam 26. The car door track guides the opening and closing of the pair of car doors 12.

[0036] Multiple door boots (not shown) are provided at the lower end of each car door 12. A car sill (not shown) is provided on the car floor 23. A sill groove is provided on the car sill. Multiple door boots are inserted into the sill groove.

[0037] Each connecting arm 17 is connected between the door support frame 16 and the corresponding longitudinal post 22. In embodiment 1, each connecting arm 17 is fixed relative to the crossbeam 26 and protrudes horizontally from the crossbeam 26 toward the corresponding longitudinal post 22.

[0038] Two rollers 18 are rotatably mounted on each connecting arm 17. The two rollers 18 of each connecting arm 17 clamp the longitudinal column 22 in the longitudinal direction of the car chamber 11. Thus, each connecting arm 17 can be displaced vertically relative to the corresponding longitudinal column 22. Each longitudinal column 22 is a guide member in Embodiment 1. The longitudinal direction of the car chamber 11 is perpendicular to and horizontal to the width direction of the car chamber 11. Figure 2 and Figure 3 The left and right directions.

[0039] In this elevator car assembly 8, the crossbeam 26 is not installed on the car body 24, but is fixed to a pair of corner posts 25. Furthermore, the pair of corner posts 25 stand upright on the car floor 23. Additionally, each connecting arm 17 can be moved vertically relative to its corresponding longitudinal post 22.

[0040] Therefore, compared with the case where the crossbeam 26 is fixed in the car body 24, the vibration of the car body 24 during the opening and closing of the pair of car doors 12 can be suppressed.

[0041] Furthermore, when the compression of the multiple vibration damping components 15 is large, the door support frame 16 also shifts downward relative to the floor frame 21 along with the car floor 23. Therefore, it is possible to suppress the reduction in the fit between the multiple door shoes and the sill groove. This, in turn, improves the resistance to the car doors 12 detaching from the crossbeam 26.

[0042] In addition, the door support frame 16 and a pair of longitudinal columns 22 are connected by a pair of connecting arms 17, thus enabling the door support frame 16 to be more securely held on the car floor 23.

[0043] Furthermore, each connecting arm 17 can be moved vertically along the longitudinal column 22, which serves as a guide member. Therefore, compared to the case where a longitudinal member different from the longitudinal column 22 is provided as a guide member in the car frame 10, the increase in the number of members can be suppressed.

[0044] Furthermore, the two rollers 18 in each connecting arm 17 clamp the longitudinal column 22 in the front-rear direction of the car chamber 11. Therefore, it is possible to suppress the tilting of the door support frame 16 in the front-rear direction of the car chamber 11 and to allow the door support frame 16 to move smoothly relative to the car frame 10 in the vertical direction.

[0045] Alternatively, a longitudinal member different from the longitudinal column 22 can be provided on the car frame 10 as a guide member. For example, an arm protruding toward the door support frame 16 can be installed on the longitudinal column 22 or the upper frame, and the longitudinal member serving as a guide member can be installed at the front end of the arm. This can shorten the length of the connecting arm 17 and increase the degree of freedom in the position of the connecting arm 17.

[0046] Implementation method 2.

[0047] then, Figure 4 This is a top view of the elevator car assembly 8 according to Embodiment 2. In Embodiment 2, a pair of track components 31 are fixed to each longitudinal column 22 such that the longitudinal column 22 is sandwiched between the longitudinal column 22 in the front-rear direction of the car compartment 11.

[0048] On each connecting arm 17, a pair of linear guides 32 are spaced apart from each other in the longitudinal direction of the car chamber 11. Each linear guide 32 contacts a corresponding track component 31. The pair of linear guides 32 on each connecting arm 17 clamps the corresponding longitudinal column 22 in the longitudinal direction of the car chamber 11 across the corresponding pair of track components 31. Thus, each connecting arm 17 can be moved vertically relative to the corresponding longitudinal column 22, that is, it can slide.

[0049] The other structures in Implementation 2 are the same as those in Implementation 1.

[0050] Based on this structure, the same effect as in Implementation Method 1 can be obtained.

[0051] Implementation method 3.

[0052] then, Figure 5 This is a top view showing a portion of the elevator car assembly 8 according to Embodiment 3. In Embodiment 3, each connecting arm 17 is fixed to the corresponding longitudinal column 22.

[0053] Two rollers 18 in each connecting arm 17 clamp the corner post 25 in the front-rear direction of the car chamber 11. Thus, each connecting arm 17 can be displaced vertically relative to the corresponding corner post 25. Each corner post 25 is a guide member in Embodiment 3.

[0054] The other structures in Implementation 3 are the same as those in Implementation 1.

[0055] Based on this structure, the same effect as in Implementation Method 1 can be obtained.

[0056] In addition, in embodiment 3, the same structure as in embodiment 2 can be used instead of multiple rollers 18, so that each connecting arm 17 can slide in the vertical direction relative to the corresponding corner post 25.

[0057] Furthermore, the overall layout of the elevator is not limited to Figure 1 The layout. For example, the rope winding method can also be a 2:1 rope winding method.

[0058] In addition, elevators can also be machine-room-less elevators, double-decker elevators, and single-shaft multi-car elevators. A single-shaft multi-car elevator is one in which the upper car and the lower car, located directly below the upper car, move independently up and down in a common shaft.
