[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a schematic diagram showing an elevator according to embodiment 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 an elevator control device 5 are installed.

[0010] The hoist 3 has a drive sheave 6, a hoist motor (not shown), and a hoist brake (not shown). The hoist motor rotates the drive sheave 6. The hoist brake keeps the drive sheave 6 stationary. The hoist brake also brakes the rotation of the drive sheave 6.

[0011] A suspension body 7 is wound around the drive sheave 6 and the deflector sheave 4. A plurality of ropes or a plurality of belts are used as the suspension body 7. A cage device 8 is connected to a first end of the suspension body 7. A counterweight 9 is connected to a second end of the suspension body 7.

[0012] The car device 8 and the counterweight 9 are suspended by a suspension body 7, and move up and down in the hoistway 1 by rotating the drive sheave 6. The elevator control device 5 controls the operation of the car device 8 by controlling the hoisting machine 3.

[0013] 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 ascent and descent of the car device 8. The pair of counterweight guide rails guide the ascent and descent of the counterweight 9.

[0014] The car device 8 has a car frame 10, a car chamber 11, and a pair of car doors 12. The suspension body 7 is connected to the car frame 10. The car chamber 11 is supported by the car frame 10. A car entrance / exit is provided in the car chamber 11. The pair of car doors 12 open and close the car entrance / exit.

[0015] A door controller 13 is provided on the car device 8. The door controller 13 controls the opening and closing operation of the car door 12.

[0016] Each of the landings on multiple floors is provided with a pair of landing doors 14. At each landing, the pair of landing doors 14 opens and closes the landing entrance / exit. Also, at each landing, the pair of landing doors 14 opens and closes in conjunction with the pair of car doors 12 when the car device 8 lands on the floor.

[0017] Fig. 2 is a side view showing the cage device 8 in Fig. 1. Fig. 3 is a plan view showing the cage device 8 in Fig. 2.

[0018] Although not shown in FIG. 1, the car device 8 further includes a plurality of vibration isolation members 15, a door support frame 16, a pair of connecting arms 17, and a plurality of rollers 18.

[0019] The car frame 10 has a floor frame 21, a pair of vertical columns 22, each of which is a vertical member, and an upper beam (not shown). The pair of vertical columns 22 are each erected vertically on the floor frame 21. The upper beam is horizontally installed between the upper ends of the pair of vertical columns 22.

[0020] The car chamber 11 is disposed between a pair of vertical pillars 22. The car chamber 11 also has a flat car floor 23 and a car chamber body 24. The car floor 23 is supported on a floor frame 21. The car chamber body 24 is provided on the car floor 23. The car entrance / exit is provided on the front surface of the car chamber body 24.

[0021] The multiple vibration-isolating members 15 are interposed between the floor frame 21 and the car floor 23. The multiple vibration-isolating members 15 are made of a material, for example, rubber. The multiple vibration-isolating members 15 suppress the transmission of vibration from the car frame 10 to the car chamber 11 when the car device 8 is traveling. In addition, the multiple vibration-isolating members 15 suppress vibration of the car chamber 11 caused by passengers getting on and off the car chamber 11.

[0022] The door support frame 16 has a pair of corner posts 25 and a girder 26. The pair of corner posts 25 are spaced apart from each other in the width direction of the car chamber 11 and stand vertically on the car floor 23. The width direction of the car chamber 11 is a direction parallel to the direction in which the pair of car doors 12 are opened and closed, and is the up-and-down direction in Figure 3.

[0023] The girder 26 is horizontally installed between the upper ends of the pair of corner posts 25. That is, the girder 26 is supported by the car floor 23 via the pair of corner posts 25. The girder 26 is located above the car entrance.

[0024] The pair of car doors 12 are suspended from a beam 26. A car door rail (not shown) is provided on the beam 26. The car door rail guides the opening and closing operation of the pair of car doors 12.

[0025] A plurality of door shoes (not shown) are provided at the lower end of each car door 12. A car threshold (not shown) is provided on the car floor 23. The car threshold is provided with a threshold groove. A plurality of door shoes are inserted into the threshold groove.

[0026] Each connecting arm 17 is connected between the door support frame 16 and a corresponding vertical pillar 22. In the first embodiment, each connecting arm 17 is fixed to a girder 26 and protrudes horizontally from the girder 26 toward the corresponding vertical pillar 22.

[0027] Two rollers 18 are rotatably provided on each connecting arm 17. The two rollers 18 on each connecting arm 17 sandwich a vertical pillar 22 in the front-to-rear direction of the car chamber 11. This allows each connecting arm 17 to be displaced in the up-down direction relative to the corresponding vertical pillar 22. Each vertical pillar 22 is a guide member in the first embodiment. The front-to-rear direction of the car chamber 11 is a horizontal direction perpendicular to the width direction of the car chamber 11, and corresponds to the left-to-right direction in Figures 2 and 3.

[0028] In such an elevator car device 8, the girder 26 is not attached to the car room body 24, but is fixed to a pair of corner posts 25. The pair of corner posts 25 are erected on the car floor 23. Each connecting arm 17 is vertically displaceable with respect to the corresponding vertical column 22.

[0029] Therefore, compared to a case in which the girder 26 is fixed to the car body 24, vibration of the car body 24 during the opening and closing operations of the pair of car doors 12 can be suppressed.

[0030] In addition, even when the compression amount of the multiple vibration-proof members 15 is large, the door support frame 16 is displaced downward together with the car floor 23 relative to the floor frame 21. This makes it possible to prevent the engagement allowances of the multiple door shoes in the threshold grooves from becoming smaller. This makes it possible to improve the resistance against each car door 12 coming off the girder 26.

[0031] In addition, since the door support frame 16 and the pair of vertical pillars 22 are connected by the pair of connecting arms 17, the door support frame 16 can be held on the car floor 23 more firmly.

[0032] In addition, each connecting arm 17 can be displaced in the vertical direction along the vertical pillars 22 serving as guide members. Therefore, an increase in the number of parts can be suppressed compared to a case in which a vertical member other than the vertical pillars 22 is provided on the car frame 10 as a guide member.

[0033] In addition, the two rollers 18 of each connecting arm 17 sandwich the vertical pillar 22 in the front-rear direction of the car chamber 11. Therefore, the door support frame 16 can be smoothly displaced in the up-down direction relative to the car frame 10 while suppressing the collapse of the door support frame 16 in the front-rear direction of the car chamber 11.

[0034] The car frame 10 may be provided with a vertical member other than the vertical pillar 22 as a guide member. For example, an arm protruding toward the door support frame 16 may be attached to the vertical pillar 22 or the upper frame, and a vertical member as a guide member may be attached to the tip of the arm. This allows the length of the connecting arm 17 to be shortened and improves the degree of freedom in the position of the connecting arm 17.

[0035] Embodiment 2 4 is a plan view showing an elevator car device 8 according to embodiment 2. In embodiment 2, a pair of rail members 31 are fixed to each vertical pillar 22 so as to sandwich the vertical pillar 22 in the front-rear direction of the car chamber 11.

[0036] Each connecting arm 17 is provided with a pair of linear guides 32 spaced apart from each other in the front-rear direction of the car chamber 11. Each linear guide 32 contacts a corresponding rail member 31. The pair of linear guides 32 provided on each connecting arm 17 sandwich the corresponding vertical pillar 22 in the front-rear direction of the car chamber 11 via the corresponding pair of rail members 31. This allows each connecting arm 17 to be displaced, i.e., slidable, in the up-down direction relative to the corresponding vertical pillar 22.

[0037] Other configurations in the second embodiment are similar to those in the first embodiment.

[0038] With this configuration as well, the same effects as those of the first embodiment can be obtained.

[0039] Embodiment 3 5 is a plan view showing a part of an elevator car device 8 according to embodiment 3. In embodiment 3, each connecting arm 17 is fixed to a corresponding vertical pillar 22.

[0040] The two rollers 18 of each connecting arm 17 sandwich a corner post 25 in the front-rear direction of the car chamber 11. This allows each connecting arm 17 to be displaced in the up-down direction relative to the corresponding corner post 25. Each corner post 25 is a guide member in the third embodiment.

[0041] Other configurations in the third embodiment are similar to those in the first embodiment.

[0042] With this configuration as well, the same effects as those of the first embodiment can be obtained.

[0043] In the third embodiment, a configuration similar to that of the second embodiment may be used instead of the multiple rollers 18, and each connecting arm 17 may be made slidable in the up and down direction relative to the corresponding corner post 25.

[0044] Moreover, the layout of the entire elevator is not limited to the layout in Fig. 1. For example, the roping system may be a 2:1 roping system.

[0045] The elevator may be a machine room-less elevator, a double deck elevator, a one-shaft multi-car elevator, etc. The one-shaft multi-car elevator is a system in which an upper car and a lower car arranged directly below the upper car each independently ascend and descend in a common elevator shaft.
