When the car 4 is lifted in this state, the direction is opposite to the landing side along the inclined form of the sheet body 20c of the first covering body 20 and the inclined form of the sheet body 21c of the second covering body 21. An air flow is generated, and the air resistance received by the car 4 is reduced. Accordingly, the vibration of the side plate that defines the room 10 of the car 4 of the car 4 is suppressed, and the running noise is reduced.

  According to the elevator apparatus 1 according to the first embodiment configured as described above, the covering body that reduces the air resistance when the car 4 is raised includes the sheet body 20c made of a tent sheet and the shaft portion 20a made of a synthetic resin. , 20b, a sheet body 21c made of a tent sheet, and a second cover body 21 having shaft portions 21a, 21b made of synthetic resin. Therefore, a lightweight covering can be realized. Thereby, the load with respect to an elevator system can be reduced.

  Further, the covering body provided in the first embodiment has a simple structure and is easy to manufacture, and since it is lightweight as described above, it can be manufactured in a relatively short time. The installation work to the car 4 can be easily performed. Thereby, the work efficiency of the work for manufacturing the covering body and the installation work for the car 4 can be improved. Further, at the time of maintenance work of the equipment installed on the mounting base 15 performed on the car room 10 or the control box installed on the mounting base 16, the sheet body 20c of the first covering body 20 is wound up and wound. The taken first covering 20 can be held by the first bracket 22. Further, the sheet body 21 c of the second covering body 21 can be wound up, and the wound second covering body 21 can be held by the second bracket 23. Thereby, a wide work space can be secured on the car room 10, and good workability of maintenance work and work safety can be secured.

  The elevator apparatus according to the second embodiment of the present invention shown in FIGS. 6 and 7 includes a guide member that guides the covering when the covering is expanded. The guide member includes a curved surface guide 40 that guides the first covering body 20, and a rod-shaped guide 41 that includes a plurality of rod bodies that guide the second covering body 21.

  In the second embodiment, the length of the column 17 is set so that the upper end of the column 17 is lower than the upper frame 11. Further, the hook 31 provided at the other end of the first covering body 20 is engaged with a hole formed in the mounting base 16. Thereby, the sheet body 20c of the first covering body 20 is configured to form a partially curved surface in which the attachment base 16 side is low and the first bracket 22 side is high.

  The curved surface guide 40 is fixed to the mounting base 15, and an upper portion that contacts the sheet body 20 c of the first covering body 20 is formed into a curved surface.

  The rod-shaped guide 41 is provided so as to extend in the horizontal direction, and both end portions thereof are fixed to brackets (not shown) fixed to the mounting base 15. With this rod-shaped guide 41, the sheet body 21c of the second covering body 21 has a form in which the side closer to the landing is raised and the side far from the landing is lowered in a stepped shape. Other configurations are the same as those of the first embodiment.

  In the second embodiment, when the car 4 is raised, the first covering body 20 generates an air flow toward the landing side, and the second covering body 21 generates an air flow toward the opposite side to the landing side. To do. By these air flows, the air resistance received by the car room 10 of the car 4 is reduced as in the first embodiment. Accordingly, the vibration of the side plate of the cab 10 is suppressed, and the traveling sound is reduced. That is, since this 2nd Embodiment is also provided with the 1st covering body 20 and the 2nd covering body 21 equivalent to 1st Embodiment, the effect equivalent to 1st Embodiment is acquired.

  In the second embodiment, the first covering body 20 is reinforced by the curved surface guide 40 and the second covering body 21 is reinforced by the rod-shaped guide 41 when the car 4 is raised, so that the car 4 is raised. At this time, the first covering body 20 and the second covering body 21 can be maintained in a stable form.

  In the first and second embodiments, the covering body is provided on the upper portion of the car 4. However, a covering body having a similar configuration may be provided on the lower portion of the car 4. With such a configuration, when the car 4 is lowered, an air flow is generated by the covering body so that the air resistance received by the car room 10 of the car 4 can be reduced, and traveling noise can be suppressed to a low level.

  In the first and second embodiments, the predetermined holding portion that holds the covering member includes the first bracket 22 that holds the first covering member 20 on which the sheet member 20c is wound, and the sheet member 21c that is wound. Although comprised by the 2nd bracket 23 holding the taken 2nd covering body 21, this invention is not restricted to comprising in this way. The predetermined holding part may be set at the upper part or the lower part of the car room 10 of the car 4. Further, the predetermined holding portion may be set to any one of the mounting base 15, the mounting base 16, the pillar 17, and the handrail 18 that constitute the peripheral member of the cab 10. Further, the predetermined holding unit may be set on the frame member 9 such as the upper frame 11 and the vertical frame 12.

  In the first and second embodiments, the shaft portions 20a and 20b of the first covering body 20 and the shaft portions 21a and 21b of the second covering body 21 are made of synthetic resin. The parts 20a, 20b, 21a, 21b may be made of a metal material or rigid wood.

  In the first and second embodiments, the hooks 31 and 35 are provided. However, a magnet is provided instead of the hooks 31 and 35, and the covering body is attached to and detached from the predetermined holding portion via the magnet. It may be configured. In the case where the magnet is provided as described above, the covering body can be easily attached to and detached from the predetermined holding portion.

  Moreover, in 1st, 2nd embodiment, although the covering body is divided | segmented by the 1st covering body 20 and the 2nd covering body 21, this invention comprises a covering body in this way. It is not limited to that. As long as it takes into account the formation of a notch hole for avoiding interference with the main rope 6 and a notch communicating with the notch hole, the covering body may have a single sheet body that is not divided. Good.

  In the case of a covering body having a single sheet body that is not divided, a portion of the sheet body on the side close to the landing is wound up and held by the first bracket 22, and a portion of the sheet body on the side far from the landing May be wound and held by the second bracket 23.

  The first and second embodiments can also be applied to a view hoistway including a transparent body such as transparent glass that allows the outside of the hoistway 3 to be viewed from the car room 10 of the car 4. . In the case where such a hoistway for observation is provided, the covering body is extended to the floor 14 shown in FIG. 2 so as to face the transparent body, and the portion of the extending covering body is You may make it the structure provided with the display body which can be visually observed from the outside of the hoistway for water. The display body may form a colored design surface, may display an advertisement, or may be a display that can be rolled up.

  In general, the car room 10 of the car 4 includes a side plate that defines the interior of the room and an outer wall plate that is disposed outside the side plate. Therefore, in the case where the display body is provided by extending the covering body to the floor 14 as described above, the outer wall plate at the location of the cab 10 facing the portion of the covering body including the display body is omitted. The covering body may be arranged to face the side plate of the cab 10. In such a configuration, since a part of the outer wall plate of the car room 10 is omitted, the structure becomes simple, and the manufacturing cost of the car room 10 can be reduced.

  The configuration of each unit is not limited to the illustrated embodiment, and various modifications can be made without departing from the gist of the present invention.
