[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 Fig. 1 is a schematic configuration diagram showing an elevator according to embodiment 1. In Fig. 1, a machine room 12 is provided above a hoistway 11. In the machine room 12, an elevator hoisting machine 13 is installed.

[0010] The elevator hoist 13 has a hoist body 14, a drive sheave 15, and a deflector sheave 16. The hoist body 14 has a hoist motor (not shown) and a hoist brake (not shown). The hoist motor rotates the drive sheave 15. The hoist brake keeps the drive sheave 15 stationary. The hoist brake also brakes the rotation of the drive sheave 15.

[0011] A suspension body 17 is wound around the drive sheave 15 and the deflector sheave 16. A plurality of ropes or a plurality of belts are used as the suspension body 17. A cage 18 is connected to a first end of the suspension body 17. A counterweight 19 is connected to a second end of the suspension body 17.

[0012] The car 18 and the counterweight 19 are suspended in the hoistway 11 by a suspension 17. The car 18 and the counterweight 19 move up and down in the hoistway 11 by rotating the drive sheave 15.

[0013] Fig. 2 is a front view showing the elevator hoist 13 of Fig. 1. Although omitted in Fig. 1, the elevator hoist 13 further has a machine bed 20. The machine bed 20 is installed on the floor of the machine room 12. The hoist main body 14 and the deflector sheave 16 are supported by the machine bed 20.

[0014] Although omitted in Fig. 1, the elevator hoisting machine 13 is provided with a suspended body cover device 21. The suspended body cover device 21 has a cover body 22, a first holding member 23, and a second holding member 24.

[0015] The cover body 22 covers the covered portion 17a of the suspension body 17. The covered portion 17a is an inclined portion between the drive sheave 15 and the deflector wheel 16 in the suspension body 17.

[0016] The first holding member 23 is attached to the housing of the hoist body 14. In addition, the first holding member 23 holds the end of the cover body 22 on the drive sheave 15 side, that is, the upper end.

[0017] The second holding member 24 is attached to the machine base 20. In addition, the second holding member 24 holds the end portion of the cover body 22 on the deflector wheel 16 side, that is, the lower end portion.

[0018] Fig. 3 is a plan view showing the suspension body cover device 21 of Fig. 2. Fig. 4 is a side view of the suspension body cover device 21 of Fig. 3 as viewed along the arrow IV. Fig. 5 is a front view of the suspension body cover device 21 of Fig. 3 as viewed along the arrow V.

[0019] The cover body 22 has a plurality of support rods 25 and a sheet member 26. The plurality of support rods 25 are arranged parallel to one another along the covered portion 17a. In this example, four support rods 25 are used. As shown in Fig. 5, the four support rods 25 are arranged so as to surround the covered portion 17a.

[0020] An end of each support rod 25 on the drive sheave 15 side is passed through a first holding member 23 and held by the first holding member 23. An end of each support rod 25 on the deflector wheel 16 side is passed through a second holding member 24 and held by the second holding member 24.

[0021] The sheet member 26 is supported by a plurality of support rods 25. In other words, the plurality of support rods 25 form a framework that supports the sheet member 26. The sheet member 26 is made of a flexible material. Examples of materials for the sheet member 26 include flame-retardant polyester, nylon, and the like.

[0022] A plurality of cylindrical portions 26a are provided on the sheet member 26. In this example, a pair of cylindrical portions 26a are provided on both ends of the sheet member 26.

[0023] Of the multiple support rods 25, a pair of support rods 25 located at both ends of the sheet member 26, i.e., a pair of support rods 25 located below the covered portion 17a, are passed through a pair of cylindrical portions 26a. Also, the remaining pair of support rods 25 out of the multiple support rods 25, i.e., a pair of support rods 25 located above the covered portion 17a, is hung with a sheet member 26. As a result, the sheet member 26 covers the left and right and the top of the covered portion 17a, as shown in FIG.

[0024] A hook 23a is provided on the first holding member 23. A fastening hole 26b is provided on the end of the sheet member 26 on the first holding member 23 side. The hook 23a is passed through the fastening hole 26b. That is, the sheet member 26 is hung on the hook 23a. This prevents the sheet member 26 from being separated from the first holding member 23.

[0025] The dimension of sheet member 26 in the longitudinal direction of covered portion 17a is larger than the dimension of covered portion 17a in the longitudinal direction. Therefore, surplus portion 26c is generated in sheet member 26. This surplus portion 26c is received by second holding member 24 in a state where it is gathered toward second holding member 24 and multiple wrinkles are formed.

[0026] Fig. 6 is an exploded side view of the support rod 25 of Fig. 4. Each support rod 25 is formed by joining together a plurality of rod pieces 27. That is, each support rod 25 can be divided into a plurality of rod pieces 27.

[0027] The length of each rod piece 27 can be adjusted by changing the number of rod pieces 27 that are joined together.

[0028] Each rod piece 27 has a cylindrical large diameter portion 27a and a cylindrical small diameter portion 27b. The small diameter portion 27b is adjacent to the large diameter portion 27a. The small diameter portion 27b of each rod piece 27 is inserted into the large diameter portion 27a of the adjacent rod piece 27.

[0029] A plurality of first retaining holes (not shown) are provided in the first retaining member 23. A corresponding support rod 25 is passed through each of the first retaining holes. The inner diameter of each of the first retaining holes is larger than the outer diameter of the large diameter portion 27a.

[0030] As shown in Fig. 5, the second holding member 24 is provided with a plurality of second holding holes 24a. The inner diameter of each second holding hole 24a is larger than the outer diameter of the small diameter portion 27b and smaller than the outer diameter of the large diameter portion 27a. The small diameter portion 27b located at the tip of the corresponding support rod 25 is inserted into each second holding hole 24a. This prevents each support rod 25 from moving toward the deflector wheel 16 with respect to the first holding member 23 and the second holding member 24.

[0031] In such an elevator suspension cover device 21, the cover body 22 has a plurality of support rods 25 and a sheet member 26. The sheet member 26 is made of a flexible material. The sheet member 26 is provided with a plurality of cylindrical portions 26a. A support rod 25 passes through each cylindrical portion 26a.

[0032] This makes it possible to reduce the weight of the cover body 22. Furthermore, the cover body 22 can be made compact, making it easy to transport and store.

[0033] In addition, the length of each support rod 25 is adjustable. Therefore, the cover body 22 made of the same part can be applied to a plurality of elevator hoisting machines 13 having different lengths of the covered portion 17a, which can reduce the number of types of the cover body 22. In addition, the cover body 22 can be further easily transported and stored.

[0034] Furthermore, each support rod 25 is constructed by joining a plurality of rod pieces 27. Therefore, the length of each support rod 25 can be adjusted with a simple structure.

[0035] Moreover, a hook 23a is provided on the first holding member 23. A sheet member 26 is hooked onto the hook 23a. Moreover, the second holding member 24 receives an excess portion of the sheet member 26. Therefore, with a simple configuration, it is possible to cover covered portions 17a having different lengths.

[0036] In the first embodiment, three or more cylindrical portions 26a may be provided on the sheet member 26, and three or more support rods 25 may be passed through the cylindrical portions 26a.

[0037] Embodiment 2 7 is a front view showing the cover body 22 of the suspension body cover device according to embodiment 2. The number of cylindrical parts 26a in embodiment 2 is greater than the number of support rods 25 passed through cylindrical parts 26a.

[0038] The width dimension of the cover body 22 can be changed by changing the combination of the cylindrical parts 26a through which the multiple support rods 25 pass. The width dimension of the cover body 22 is the dimension in the direction perpendicular to the longitudinal direction of the support rods 25 and perpendicular to the vertical direction.

[0039] Other configurations in the second embodiment are similar to those in the first embodiment.

[0040] In such a suspension body cover device, the width dimension of the cover body 22 is changeable. Therefore, the cover body 22 made of the same part can be applied to a plurality of elevator hoists 13 having different width dimensions of the covered portions 17a.

[0041] For example, when multiple ropes are used as the suspension body 17, the cover body 22 made of the same part can be applied to the elevator hoists 13 of multiple elevators having different numbers of ropes, while preventing the width dimension of the cover body 22 from becoming larger than necessary.

[0042] It should be noted that there is no particular limitation on the number and positions of the cylindrical portions 26a in the embodiment 2. For example, the cylindrical portions 26a may be provided at equal intervals over the entirety of the sheet member 26.

[0043] In the first and second embodiments, each of the support rods 25 may be extendable and retractable, so that the length of each of the support rods 25 can be continuously adjusted.

[0044] Although the preferred embodiments have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the claims.

[0045] Various aspects of the present disclosure are summarized below as appendices.
