[0009] Embodiment 1 An elevator according to the first embodiment will be described. Figures 1 and 2 are diagrams showing the overall configuration of an elevator according to the present embodiment. The up and down directions in Figures 1 and 2 represent the vertical up and down directions. Figure 1 shows the configuration of the elevator when the car 11 is located at the top of the hoistway 10. Figure 2 shows the configuration of the elevator when the car 11 is located at the bottom of the hoistway 10.

[0010] As shown in Figs. 1 and 2, a car 11 is provided in the elevator shaft 10. The car 11 is configured to move up and down in the elevator shaft 10. The elevator shaft 10 is guided in its upward and downward movement by a car guide rail (not shown). A control panel 12 is fixed to the elevator shaft 10. The control panel 12 is configured to control the upward and downward movement of the car 11.

[0011] The control panel 12 and the car 11 are connected by a cable 13. The cable 13 is configured to supply power and transmit signals between the control panel 12 and the car 11. The cable 13 is flexible.

[0012] One end of the cable 13 is connected to the control panel 12 via a cable hoisting device 14. The cable hoisting device 14 is fixed to the hoistway 10. The cable hoisting device 14 may be fixed to the hoistway 10 via another member, such as a member that supports the control panel 12. The cable hoisting device 14 is located below the control panel 12. The cable 13 is suspended by the cable hoisting device 14.

[0013] The other end of cable 13 is connected to car 11 via cable suspension device 15. Cable suspension device 15 is fixed to car 11. Cable suspension device 14 is located below car 11. Cable 13 is suspended by cable suspension device 15. The position of the other end of cable 13 moves in accordance with the rise and fall of car 11. The weight of cable 13 is supported by cable suspension device 14 and cable suspension device 15.

[0014] The cable suspension device of this embodiment will be described below. The cable suspension device of this embodiment is applied to both the cable suspension device 14 on the control panel 12 side and the cable suspension device 15 on the car 11 side. The cable suspension device of this embodiment will be described below using the cable suspension device 14 as an example. Note that the cable suspension device of this embodiment may be applied to only one of the cable suspension device 14 and the cable suspension device 15.

[0015] Fig. 3 is a front view showing the configuration of an elevator cable suspension device according to this embodiment. Fig. 4 is a side view showing the configuration of an elevator cable suspension device according to this embodiment. The up and down directions in Figs. 3 and 4 represent the vertical up and down directions. Fig. 4 shows the configuration of cable suspension device 14 when viewed along the extension directions of first columnar member 21, second columnar member 22, and third columnar member 23.

[0016] 3 and 4, the cable suspension device 14 has a first pillar member 21, a second pillar member 22, a third pillar member 23, a first support member 31, and a second support member 32. The cable 13 extends vertically in the up-down direction as a whole.

[0017] The first columnar member 21, the second columnar member 22, and the third columnar member 23 each extend in a direction intersecting the vertical direction. In this embodiment, the first columnar member 21, the second columnar member 22, and the third columnar member 23 all extend in the horizontal direction and are arranged parallel to one another. The first columnar member 21, the second columnar member 22, and the third columnar member 23 are arranged side by side in the vertical direction.

[0018] The second columnar member 22 is disposed lower than the first columnar member 21. The third columnar member 23 is disposed further lower than the second columnar member 22. The second columnar member 22 is located between the first columnar member 21 and the third columnar member 23 in the up-down direction. A gap 24 is formed between the first columnar member 21 and the second columnar member 22. The cable 13 passes through the gap 24. The distance between the first columnar member 21 and the second columnar member 22 in the vertical up-down direction is equal to or greater than the thickness of the cable 13. A gap 25 is formed between the second columnar member 22 and the third columnar member 23. The cable 13 passes through the gap 25. The distance between the second columnar member 22 and the third columnar member 23 in the vertical up-down direction is equal to or greater than the thickness of the cable 13.

[0019] Each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 has a columnar or cylindrical shape. That is, each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 has a cylindrical outer circumferential surface. The first columnar member 21, the second columnar member 22, and the third columnar member 23 have the same diameter and extension direction length. For example, each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 is formed from a steel pipe, which is easily available and inexpensive.

[0020] A cylindrical shaft portion 21a is formed at one end of the first columnar member 21 in the extension direction. The shaft portion 21a has a diameter smaller than that of the first columnar member 21. The shaft portion 21a protrudes from the first columnar member 21 along the central axis of the first columnar member 21. A cylindrical shaft portion 21b is formed at the other end of the first columnar member 21 in the extension direction. The shaft portion 21b has a diameter smaller than that of the first columnar member 21. The shaft portion 21b protrudes from the first columnar member 21 along the central axis of the first columnar member 21. The shaft portions 21a and 21b are fixed to the first columnar member 21.

[0021] Similarly, a cylindrical shaft portion 22a is formed at one end of the second columnar member 22 in the extension direction. The shaft portion 22a has a diameter smaller than that of the second columnar member 22. The shaft portion 22a protrudes from the second columnar member 22 along the central axis of the second columnar member 22. A cylindrical shaft portion 22b is formed at the other end of the second columnar member 22 in the extension direction. The shaft portion 22b has a diameter smaller than that of the second columnar member 22. The shaft portion 22b protrudes from the second columnar member 22 along the central axis of the second columnar member 22. The shaft portions 22a and 22b are fixed to the second columnar member 22.

[0022] The first support member 31 and the second support member 32 each have a rectangular flat plate shape that is long in the vertical direction. The first support member 31 and the second support member 32 are arranged facing each other, sandwiching the first columnar member 21, the second columnar member 22, and the third columnar member 23. The first support member 31 supports one end of each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 in the extension direction. The second support member 32 supports the other end of each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 in the extension direction.

[0023] Holes 31a and 31b are formed in the first support member 31. Holes 32a and 32b are formed in the second support member 32. Hole 32a is disposed opposite hole 31a. Hole 32b is disposed opposite hole 31b. Holes 31a, 31b, 32a, and 32b are all formed in a circular shape.

[0024] The shaft 21a is rotatably inserted into a hole 31a of the first support member 31. The shaft 21b is rotatably inserted into a hole 32a of the second support member 32. As a result, the first columnar member 21 is supported by the first support member 31 and the second support member 32 so as to be rotatable around the central axis of the first columnar member 21.

[0025] The shaft 22a is rotatably inserted into the hole 31b of the first support member 31. The shaft 22b is rotatably inserted into the hole 32b of the second support member 32. As a result, the second pillar 22 is supported by the first support member 31 and the second support member 32 so as to be rotatable about the central axis of the second pillar 22. The second pillar 22 is attached by the installer of the cable 13 when fixing the cable 13 to the cable suspension device 14. In other words, the second pillar 22 can be attached to the first support member 31 and the second support member 32 later. The second pillar 22 may be detachable from the first support member 31 and the second support member 32.

[0026] One end of the third columnar member 23 is fixed to the first support member 31 by welding or the like. The other end of the third columnar member 23 is fixed to the second support member 32 by welding or the like. As a result, the third columnar member 23 is supported by the first support member 31 and the second support member 32 so as not to rotate. In this way, at least one of the first columnar member 21, the second columnar member 22, and the third columnar member 23 is supported by the first support member 31 and the second support member 32 so as not to rotate.

[0027] Cable 13 is a flat cable having a flat cross-sectional shape. Cable 13 has a first surface 13a and a second surface 13b. First surface 13a and second surface 13b are both surfaces along the width direction of cable 13. Second surface 13b is the surface opposite to the first surface. Cable 13 may also be a round cable having a circular cross-sectional shape.

[0028] In the front view shown in FIG. 3 , the cable 13 is located between the first support member 31 and the second support member 32, and overlaps with the first columnar member 21, the second columnar member 22, and the third columnar member 23. The outer peripheral surfaces of the first columnar member 21 and the third columnar member 23 are in contact with the first surface 13a of the cable 13. The outer peripheral surface of the second columnar member 22 is in contact with the second surface 13b of the cable 13. The cable 13 is pressed between the first columnar member 21 and the third columnar member 23 by the second columnar member 22. The cable 13 is bent along the outer peripheral surfaces of the first columnar member 21, the second columnar member 22, and the third columnar member 23.

[0029] Pressing forces are applied to the cable 13 by the first columnar member 21, the second columnar member 22, and the third columnar member 23. The direction of the pressing force by the second columnar member 22 is to the right in FIG. 4. The direction of the pressing forces by the first columnar member 21 and the third columnar member 23 is opposite to the direction of the pressing force by the second columnar member 22, that is, to the left in FIG. 4. The cable 13 is curved so as to be convex in the direction of the pressing force by the second columnar member 22.

[0030] Here, the contact portion between the first columnar member 21 and the cable 13 is referred to as contact portion 41. The contact portion between the second columnar member 22 and the cable 13 is referred to as contact portion 42. The contact portion between the third columnar member 23 and the cable 13 is referred to as contact portion 43. A straight line passing through contact portion 41 and contact portion 43 is referred to as line 44. In a side view taken along the extension direction of the second columnar member 22, contact portion 42 is located closer to the direction of the pressing force of the second columnar member 22 acting on the cable 13 than line 44.

[0031] These pressing forces generate frictional forces between the first columnar member 21, the second columnar member 22, and the third columnar member and the cable 13. These frictional forces allow the cable suspension device 14 to support the vertical load of the cable 13.

[0032] Next, a method for fixing the cable 13 to the cable suspension device 14 will be described. Fig. 5 is a diagram showing a method for fixing the cable to the cable suspension device of an elevator according to this embodiment. As shown in Fig. 5, the second pillar-shaped member 22 has not yet been attached to the cable suspension device 14 before the cable 13 is fixed thereto.

[0033] First, the cable 13 is sandwiched between the first columnar member 21, the third columnar member 23, and the second columnar member 22. The first columnar member 21 and the third columnar member 23 are located on the first surface 13a side of the cable 13. The second columnar member 22 is located on the second surface 13b side of the cable 13.

[0034] Next, the second columnar member 22 is pushed together with the cable 13 between the first columnar member 21 and the third columnar member 23. In this embodiment, the first columnar member 21 and the second columnar member 22 are allowed to rotate, so the second columnar member 22 and the cable 13 are pushed between the first columnar member 21 and the third columnar member 23 with a smaller force.

[0035] Next, with the second columnar member 22 and the cable 13 pressed between the first columnar member 21 and the third columnar member 23, the shaft portion 22a is fitted into the hole 31b of the first support member 31, and the shaft portion 22b is fitted into the hole 32b of the second support member 32. This causes the second columnar member 22 to be supported by the first support member 31 and the second support member 32. Through the above procedure, the cable 13 is fixed to the cable suspension device 14 as in the configuration shown in Figures 3 and 4.

[0036] As described above, the elevator according to this embodiment includes the car 11, the control panel 12, the cable 13, and the cable suspension device 14 and cable suspension device 15. The car 11 is configured to move up and down the hoistway 10. The control panel 12 is fixed to the hoistway 10. The cable 13 connects the car 11 and the control panel 12. The cable suspension device 14 and the cable suspension device 15 suspend the cable 13. The cable suspension device 14 is fixed to the control panel 12. The cable suspension device 15 is fixed to the car 11.

[0037] Each of the cable suspension devices 14 and 15 has a first columnar member 21, a second columnar member 22, a third columnar member 23, a first support member 31, and a second support member 32. The second columnar member 22 is disposed lower than the first columnar member 21. The third columnar member 23 is disposed lower than the second columnar member 22. The first support member 31 supports one end of each of the first columnar member 21, the second columnar member 22, and the third columnar member 23. The second support member 32 supports the other end of each of the first columnar member 21, the second columnar member 22, and the third columnar member 23. Each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 extends in a direction intersecting the vertical direction.

[0038] The first columnar member 21 and the third columnar member 23 are in contact with a first surface 13a of the cable 13. The second columnar member 22 is in contact with a second surface 13b of the cable 13, which is the surface of the cable 13 opposite to the first surface 13a. The cable 13 is bent along each of the first columnar member 21, the second columnar member 22, and the third columnar member 23. A pressing force from the second columnar member 22 acts on the cable 13. A line 44 is a straight line passing through a contact portion 41 between the first columnar member 21 and the cable 13 and a contact portion 43 between the third columnar member 23 and the cable 13. When viewed along the extension direction of the second columnar member 22, the contact portion 42 between the second columnar member 22 and the cable 13 is located closer to the direction of the pressing force from the second columnar member 22 than the line 44.

[0039] According to this configuration, the cable 13 can be fixed to each of the cable suspension devices 14 and 15 by pushing the cable 13 between the first columnar member 21 and the third columnar member 23 using the second columnar member 22. Therefore, the task of fixing the cable 13 to each of the cable suspension devices 14 and 15 can be easily performed.

[0040] In the elevator according to this embodiment, one or two of the first pillar 21, the second pillar 22, and the third pillar 23 are rotatably supported by the first support member 31 and the second support member 32. This configuration allows the second pillar 22 and the cable 13 to be pushed between the first pillar 21 and the third pillar 23 with less force. This makes it easier to secure the cable 13 to the cable suspension device 14 and the cable suspension device 15, respectively. Because at least one of the first pillar 21, the second pillar 22, and the third pillar 23 does not rotate, the vertical load of the cable 13 can be supported by the cable suspension device.

[0041] In the elevator according to this embodiment, each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 has a cylindrical outer peripheral surface. This configuration can prevent damage to the cable 13 due to contact with each of the first columnar member 21, the second columnar member 22, and the third columnar member 23. Furthermore, this configuration allows each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 to be formed from a steel pipe, which increases the availability of parts for the cable suspension device and reduces the manufacturing costs of the cable suspension device and the elevator including it.

[0042] Embodiment 2 An elevator according to the second embodiment will be described. Fig. 6 is a side view showing the configuration of a cable suspension device for an elevator according to the present embodiment. As shown in Fig. 6, no shafts are formed on either end of the first columnar member 21. One end of the first columnar member 21 is fixed to the first support member 31 by welding or the like. The other end of the first columnar member 21 is fixed to the second support member 32 by welding or the like. As a result, the first columnar member 21, like the third columnar member 23, is supported by the first support member 31 and the second support member 32 so as not to rotate. The other configuration is the same as in the first embodiment.

[0043] 7 is a diagram showing a method for fixing a cable to a cable suspension device of an elevator according to this embodiment. As shown in FIG. 7, in this embodiment, cable 13 is fixed to cable suspension device 14 by the same procedure as in embodiment 1.

[0044] In this embodiment, the first pillar member 21 and the third pillar member 23 do not rotate, so the cable 13 can be fixed to the cable suspension device 14 more firmly than in the first embodiment.

[0045] Embodiment 3 An elevator according to the third embodiment will be described. FIG. 8 is a side view showing the configuration of the elevator cable suspension device according to the present embodiment. As shown in FIG. 8, the shaft 22b of the second pillar member 22 has a rectangular pillar shape. Although not shown, the shaft 22a of the second pillar member 22 also has a rectangular pillar shape. The hole 31b of the first support member 31 and the hole 32b of the second support member 32 are both formed in a rectangular shape. As a result, the second pillar member 22 is supported by the first support member 31 and the second support member 32 so as not to rotate. The other configurations are the same as those of the second embodiment.

[0046] 9 is a diagram showing a method for fixing a cable to a cable suspension device of an elevator according to this embodiment. As shown in FIG. 9, in this embodiment, cable 13 is fixed to cable suspension device 14 by the same procedure as in embodiment 1.

[0047] In this embodiment, the first columnar member 21, the third columnar member 23, and also the second columnar member 22 do not rotate, so the cable 13 can be fixed to the cable suspension device 14 even more firmly than in embodiment 2.

[0048] Embodiment 4 An elevator according to a fourth embodiment will now be described. Fig. 10 is a side view showing the configuration of a cable suspension device of an elevator according to this embodiment. As shown in Fig. 10, the parallel arrangement direction of the first columnar member 21, the second columnar member 22, and the third columnar member 23 is inclined from the vertical up-down direction. In this way, the cable suspension device 14 may be arranged so that the parallel arrangement direction of the first columnar member 21, the second columnar member 22, and the third columnar member 23 is inclined from the vertical up-down direction.

[0049] Embodiment 5. An elevator according to a fifth embodiment will now be described. Fig. 11 is a side view showing the configuration of a cable suspension device for an elevator according to this embodiment. As shown in Fig. 11, no shafts are formed at either end of the second columnar member 22. One end of the second columnar member 22 is fixed to the first support member 31 by welding or the like. The other end of the second columnar member 22 is fixed to the second support member 32 by welding or the like. As a result, the second columnar member 22, like the third columnar member 23, is supported by the first support member 31 and the second support member 32 so as not to rotate.

[0050] The first pillar-shaped member 21 is rotatably supported by the first support member 31 and the second support member 32. The first pillar-shaped member 21 is attached by the installer of the cable 13 when fixing the cable 13 to the cable suspension device 14. In other words, the first pillar-shaped member 21 can be attached to the first support member 31 and the second support member 32 later. The first pillar-shaped member 21 may also be detachable from the first support member 31 and the second support member 32. The other configurations are the same as those in the first embodiment.

[0051] 12 and 13 are diagrams showing a method for fixing a cable to an elevator cable suspension device according to this embodiment. As shown in Fig. 12, the first pillar member 21 has not yet been attached to the cable suspension device 14 before the cable 13 is fixed thereto.

[0052] First, as shown in Fig. 12, the cable 13 is passed through the gap 25 between the second columnar member 22 and the third columnar member 23. The third columnar member 23 is located on the first surface 13a side of the cable 13. The second columnar member 22 is located on the second surface 13b side of the cable 13.

[0053] Next, the cable suspension device 14 is rotated in the direction of the thick arrow in Figure 12 around an axis parallel to the extension direction of the second columnar member 22. As a result, the cable 13 is bent along the outer circumferential surfaces of the second columnar member 22 and the third columnar member 23, as shown in Figure 13. Next, the first columnar member 21 is attached. As a result, the cable 13 is fixed to the cable suspension device 14, as in the configuration shown in Figure 11.

[0054] According to this embodiment, the process of pushing the second columnar member 22 together with the cable 13 between the first columnar member 21 and the third columnar member 23 is not necessary, so the task of fixing the cable 13 to the cable suspension device 14 can be performed with less force.

[0055] In this embodiment, the columnar member that is subsequently attached to the first support member 31 and the second support member 32 is the first columnar member 21, but the columnar member that is subsequently attached to the first support member 31 and the second support member 32 may be the third columnar member 23. In other words, in this embodiment, the first columnar member 21 or the third columnar member 23 can be subsequently attached to the first support member 31 and the second support member 32.

[0056] Embodiment 6 An elevator according to the sixth embodiment will be described. FIG. 14 is a side view showing the configuration of a cable suspension device for an elevator according to the present embodiment. As shown in FIG. 14, a notch 33 is formed in the second support member 32. The notch 33 has an open end 33a. The open end 33a is formed in an end face 32c of the second support member 32, the end face being located on the opposite side to the direction of the pressing force of the second pillar member 22 acting on the cable 13. The notch 33 extends obliquely downward from the open end 33a. The shaft portion 22b of the second pillar member 22 is inserted into the notch 33. The shaft portion 22b is located below the open end 33a of the notch 33. The other configurations are the same as those of the third embodiment.

[0057] In this embodiment, the notch 33 is formed in the second support member 32, but the notch may also be formed in the first support member 31, or may be formed in both the first support member 31 and the second support member 32.

[0058] Fig. 15 is a diagram showing a method for fixing a cable to an elevator cable suspension device according to this embodiment. As shown in Fig. 15, the second pillar 22 has not yet been attached to the cable suspension device 14 before the cable 13 is fixed thereto. When the second pillar 22 together with the cable 13 is pushed between the first pillar 21 and the third pillar 23, the shaft 22b is inserted into the notch 33 from the open end 33a and is guided by the notch 33.

[0059] As described above, in the elevator according to this embodiment, the second pillar member 22 has an end portion in the extension direction formed with a shaft portion 22b protruding from the second pillar member 22. The second support member 32 has a notch 33 formed therein. The notch 33 has an open end portion 33a on an end face 32c opposite to the direction of the pressing force of the second pillar member 22 acting on the cable 13. The notch 33 extends obliquely downward from the open end portion 33a. The shaft portion 22b is inserted into the notch 33. The shaft portion 22b is located below the open end portion 33a.

[0060] According to this configuration, the second pillar member 22 is less likely to fall off the cable suspension device 14, and therefore the mechanism for holding the second pillar member 22 to the cable suspension device 14 can be simplified.

[0061] Furthermore, with this configuration, the shaft portion 22b is guided by the notches 33, so that the second columnar member 22 can be easily pushed into between the first columnar member 21 and the third columnar member 23.

[0062] Embodiment 7 An elevator according to a seventh embodiment will be described. Fig. 16 is a side view showing the configuration of a cable suspension device of an elevator according to this embodiment. As shown in Fig. 16, irregularities 26 are formed on the outer peripheral surface of the second pillar member 22. The irregularities 26 function as a friction force increasing portion that increases the friction force generated between the second pillar member 22 and the cable 13. The other configurations are the same as those of the second embodiment.

[0063] Fig. 17 is a diagram showing a method for fixing a cable to a cable suspension device of an elevator according to this embodiment. As shown in Fig. 17, in this embodiment, cable 13 is fixed to cable suspension device 14 by the same procedure as in embodiment 1. In this embodiment, the frictional force generated between second pillar member 22 and cable 13 is increased, so cable 13 can be fixed to cable suspension device 14 more firmly.

[0064] In this embodiment, the unevenness 26 is formed as the frictional force increasing portion, but a rubber member may be wound as the frictional force increasing portion on the outer peripheral surface of the second columnar member 22. Also, in this embodiment, the frictional force increasing portion is formed on the outer peripheral surface of the second columnar member 22, but the same effect can be obtained if a frictional force increasing portion is formed on the outer peripheral surface of any of the first columnar member 21, the second columnar member 22, and the third columnar member 23.

[0065] As described above, in the elevator according to this embodiment, a frictional force increasing portion is formed on at least one of the first pillar member 21, the second pillar member 22, and the third pillar member 23. This configuration increases the frictional force generated between the cable 13 and at least one of the first pillar member 21, the second pillar member 22, and the third pillar member 23, and therefore the cable 13 can be fixed to the cable suspension device 14 more firmly.

[0066] Embodiment 8 An elevator according to the eighth embodiment will now be described. Fig. 18 is a side view showing the configuration of a cable suspension device for an elevator according to this embodiment. As shown in Fig. 18, each of the first columnar member 21, the second columnar member 22, and the third columnar member 23 has a partially cylindrical shape with a portion of the column missing. In each of the first columnar member 21, the second columnar member 22, and the third columnar member 23, the outer circumferential surface of the portion in contact with the cable 13 is formed into a cylindrical surface. The other configurations are the same as those in the second embodiment.

[0067] Embodiment 9 An elevator according to a ninth embodiment will be described. Fig. 19 is a side view showing the configuration of a cable suspension device for an elevator according to this embodiment. As shown in Fig. 19, the first pillar member 21 and the third pillar member 23 are in a twisted position. The first pillar member 21 and the second pillar member 22 are in a twisted position. The third pillar member 23 and the second pillar member 22 are in a twisted position. In this way, the first pillar member 21, the second pillar member 22, and the third pillar member 23 do not have to be arranged parallel to each other.

[0068] Embodiment 10 An elevator according to a tenth embodiment will be described. Fig. 20 is a side view showing the configuration of a cable suspension device for an elevator according to this embodiment. Fig. 21 is a perspective view showing the configuration of a second pillar-shaped member in the cable suspension device for an elevator according to this embodiment. Fig. 22 is an exploded perspective view showing the configuration of a second pillar-shaped member in the cable suspension device for an elevator according to this embodiment.

[0069] 20 to 22, a through-hole 22e is formed in the second columnar member 22. The through-hole 22e penetrates the second columnar member 22 along the extension direction of the second columnar member 22. The through-hole 22e is formed on the central axis of the second columnar member 22.

[0070] A shaft member 22d, which is a separate member from the second columnar member 22, is inserted into the through-hole 22e. The shaft member 22d is a member for fixing the second columnar member 22 to the first support member 31 and the second support member 32. The shaft member 22d has a cylindrical shape. The axial length of the shaft member 22d is longer than the length of the second columnar member 22 in the extension direction.

[0071] The hole 31b of the first support member 31 is a through-hole that penetrates the first support member 31. The hole 32b of the second support member 32 is a through-hole that penetrates the second support member 32. The shaft member 22d penetrates the hole 31b of the first support member 31, the through-hole 22e of the second columnar member 22, and the hole 32b of the second support member 32. Split pins 27 are attached to both ends of the shaft member 22d. The split pins 27 prevent the shaft member 22d from coming off the first support member 31, the second columnar member 22, and the second support member 32. The other configurations are the same as those in the second embodiment.

[0072] 23 is a diagram showing a method for fixing a cable to an elevator cable suspension device according to this embodiment. As shown in FIG. 23, when fixing a cable 13 to a cable suspension device 14, the second pillar member 22 together with the cable 13 is pushed between the first pillar member 21 and the third pillar member 23. Then, the position of the through-hole 22e is aligned with the positions of the hole 31b of the first support member 31 and the hole 32b of the second support member 32. In this state, the shaft member 22d is passed through the hole 31b, the through-hole 22e, and the hole 32b. This fixes the second pillar member 22 to the first support member 31 and the second support member 32.

[0073] After that, split pins 27 or the like are attached to both ends of the shaft member 22d. This prevents the shaft member 22d from coming off and also prevents the shaft member 22d from rotating. When the rotation of the shaft member 22d relative to the second columnar member 22 is restricted, the rotation of the second columnar member 22 is also prevented by preventing the rotation of the shaft member 22d.

[0074] As described above, in the elevator according to this embodiment, the first support member 31 has a through-hole 31b formed therein. The second support member 32 has a through-hole 32b formed therein. The second pillar member 22 has a through-hole 22e formed therein. The cable suspension device 14 further has a shaft member 22d. The shaft member 22d passes through the hole 31b of the first support member 31, the hole 32b of the second support member 32, and the through-hole 22e of the second pillar member 22.

[0075] This configuration makes it possible to prevent interference between the shaft member 22d and the first support member 31 and the second support member 32 when the second columnar member 22 is pushed between the first columnar member 21 and the third columnar member 23. After the second columnar member 22 is pushed between the first columnar member 21 and the third columnar member 23, the second columnar member 22 can be easily fixed in place by the shaft member 22d.

[0076] Embodiment 11 An elevator according to embodiment 11 will be described. Fig. 24 is a perspective view showing the configuration of a cable suspension device for an elevator according to this embodiment. Fig. 25 is an exploded perspective view showing the configuration of a cable suspension device for an elevator according to this embodiment. In Figs. 24 and 25, the first pillar member 21 and the third pillar member 23 are not shown.

[0077] 24 and 25, a first fastening member 28a and a second fastening member 28b are used as shaft members for fixing the second columnar member 22. A bolt or the like is used for each of the first fastening member 28a and the second fastening member 28b.

[0078] The hole 31b of the first support member 31 is a through-hole that penetrates the first support member 31. The hole 32b of the second support member 32 is a through-hole that penetrates the second support member 32. The first fastening member 28a fastens the first support member 31 to one end of the second columnar member 22 via the hole 31b. The second fastening member 28b fastens the second support member 32 to the other end of the second columnar member 22 via the hole 32b. The other configurations are the same as those in the tenth embodiment.

[0079] When fixing the cable 13 to the cable suspension device 14, the second columnar member 22 is pushed between the first columnar member 21 and the third columnar member 23, and then the first support member 31 and the second columnar member 22 are fastened together by the first fastening member 28a, and the second support member 32 and the second columnar member 22 are fastened together by the second fastening member 28b.

[0080] As described above, in the elevator according to this embodiment, the first support member 31 has a through-hole 31b formed therein. The second support member 32 has a through-hole 32b formed therein. The cable suspension device 14 further has a first fastening member 28a and a second fastening member 28b. The first fastening member 28a fastens the first support member 31 to one end of the second pillar-shaped member 22 via the hole 31b of the first support member 31. The second fastening member 28b fastens the second support member 32 to the other end of the second pillar-shaped member 22 via the hole 32b of the second support member 32.

[0081] This configuration prevents interference between the first fastening member 28a and the first support member 31, and between the second fastening member 28b and the second support member 32, when the second columnar member 22 is pressed between the first columnar member 21 and the third columnar member 23. After the second columnar member 22 is pressed between the first columnar member 21 and the third columnar member 23, the second columnar member 22 can be easily fixed by the first fastening member 28a and the second fastening member 28b.

[0082] Embodiment 12 An elevator according to embodiment 12 will be described below. Fig. 26 is a cross-sectional view showing the configuration of a cable suspension device for an elevator according to this embodiment.

[0083] As shown in Fig. 26, a rope-like member 29 is used as an axial member for fixing the second columnar member 22. A through-hole 22e is formed in the second columnar member 22. The hole 32b of the second support member 32 is a through-hole that passes through the second support member 32. The rope-like member 29 is passed through the through-hole 22e of the second columnar member 22 and the hole 32b of the second support member 32. One end of the rope-like member 29 is fixed to the first support member 31. The other end of the rope-like member 29 is pulled out from the hole 32b of the second support member 32 to the outside of the cable suspension device 14. The other configuration is the same as in the first embodiment, etc.

[0084] 27 is a diagram showing a method for fixing a cable to an elevator cable suspension device according to this embodiment. As shown in FIG. 27, when fixing cable 13 to cable suspension device 14, cord-like member 29 is passed through through-hole 22e of second pillar member 22 and hole 32b of second support member 32, and the other end of cord-like member 29 is pulled to the outside of cable suspension device 14. When the other end of cord-like member 29 is pulled in this state, second pillar member 22, together with cable 13, is pushed between first pillar member 21 and third pillar member 23. This makes it possible to easily fix cable 13 to cable suspension device 14.

[0085] As described above, in the elevator according to this embodiment, the cable suspension device 14 further includes a rope-like member 29. The rope-like member 29 is fixed to the first support member 31. The second support member 32 has a through-hole 32b formed therein. The second pillar member 22 has a through-hole 22e formed therein. The rope-like member 29 is passed through the through-hole 22e of the second pillar member 22 and the hole 32b of the second support member 32.

[0086] According to this configuration, by pulling the other end of the cord-like member 29, the second columnar member 22 together with the cable 13 can be easily pushed between the first columnar member 21 and the third columnar member 23. Therefore, the cable 13 can be easily fixed to the cable suspension device 14.

[0087] Embodiment 13 An elevator according to embodiment 13 will now be described. Fig. 28 is a cross-sectional view showing the configuration of a cable suspension device for an elevator according to this embodiment. The upper part of Fig. 28 shows the direction of the pressing force of second pillar-shaped members 22 acting on cables 13.

[0088] 28, the cable suspension device 14 has a first jack bolt 34a and a second jack bolt 34b. The first support member 31 has a bolt support portion 31d with a female thread formed thereon. The first jack bolt 34a passes through the female thread portion of the bolt support portion 31d. This allows the first jack bolt 34a to be supported by the first support member 31. The tip of the first jack bolt 34a is pressed against the outer peripheral surface of one end of the second columnar member 22.

[0089] The second support member 32 has a bolt support portion 32d with a female thread formed thereon. The second jack bolt 34b passes through the female thread of the bolt support portion 32d. This allows the second jack bolt 34b to be supported by the second support member 32. The tip of the second jack bolt 34b is pressed against the outer peripheral surface of the other end of the second columnar member 22.

[0090] One end of the second columnar member 22 is pressed by the first jack bolt 34a in the direction of the pressing force of the second columnar member 22 acting on the cable 13. The other end of the second columnar member 22 is pressed in the same direction by the second jack bolt 34b. This maintains the position of the second columnar member 22 in the direction of the pressing force. The other configurations are the same as those in the first embodiment.

[0091] Figure 29 is a diagram showing a method for fixing a cable to an elevator cable suspension device according to this embodiment. As shown in Figure 29, when fixing the cable 13 to the cable suspension device 14, the second pillar member 22 together with the cable 13 is pushed between the first pillar member 21 and the third pillar member 23 by the first jack bolt 34a and the second jack bolt 34b. This makes it possible to easily fix the cable 13 to the cable suspension device 14.

[0092] As described above, in the elevator according to this embodiment, the cable suspension device 14 further includes the first jack bolt 34a and the second jack bolt 34b. The first jack bolt 34a is supported by the first support member 31. The second jack bolt 34b is supported by the second support member 32. One end of the second pillar member 22 is pressed by the first jack bolt 34a in the direction of the pressing force of the second pillar member 22 acting on the cable 13. The other end of the second pillar member 22 is pressed by the second jack bolt 34b in the direction of the pressing force of the second pillar member 22 acting on the cable 13.

[0093] According to this configuration, by using the first jack bolt 34a and the second jack bolt 34b, the second columnar member 22 together with the cable 13 can be easily pushed between the first columnar member 21 and the third columnar member 23. Therefore, the cable 13 can be easily fixed to the cable suspension device 14.

[0094] Embodiment 14 An elevator according to embodiment 14 will be described. Fig. 30 is a front view showing the configuration of a cable suspension device for an elevator according to this embodiment. Figs. 31 and 32 are cross-sectional views showing the configuration of a second pillar-shaped member in the cable suspension device for an elevator according to this embodiment.

[0095] 30 to 32, a through-hole 22e is formed in the second columnar member 22. The through-hole 22e penetrates the second columnar member 22 along the extension direction of the second columnar member 22. The through-hole 22e is formed on the central axis of the second columnar member 22.

[0096] A first shaft portion 22f, a second shaft portion 22g, and an elastic body 30 are inserted into the through hole 22e. The elastic body 30 is sandwiched between the first shaft portion 22f and the second shaft portion 22g. The elastic body 30 is, for example, a compression coil spring. The first shaft portion 22f and the second shaft portion 22g are provided so as to be movable along the through hole 22e. A force is applied by the elastic body 30 to each of the first shaft portion 22f and the second shaft portion 22g in a direction that causes them to protrude axially outward from the through hole 22e. A mechanism for restricting the movement range of each of the first shaft portion 22f and the second shaft portion 22g is provided inside the through hole 22e as necessary.

[0097] 31, a portion of the first shaft portion 22f protrudes from one axial end face 22h of the second columnar member 22 and is fitted into the hole 31b of the first support member 31. A portion of the second shaft portion 22g protrudes from the other axial end face 22i of the second columnar member 22 and is fitted into the hole 32b of the second support member 32. When a force from the outside in the axial direction that resists the restoring force of the elastic body 30 is applied to the first shaft portion 22f and the second shaft portion 22g, the first shaft portion 22f and the second shaft portion 22g are housed inside the through-hole 22e as shown in FIG.

[0098] When fixing the cable 13 to the cable suspension device 14, the second columnar member 22, together with the cable 13, is pushed between the first columnar member 21 and the third columnar member 23. At this time, an axial force is applied to the first shaft portion 22f and the second shaft portion 22g from the outside, causing the first shaft portion 22f and the second shaft portion 22g to be housed inside the through-hole 22e. This prevents interference between the first shaft portion 22f and the first support member 31 and between the second shaft portion 22g and the second support member 32. When the position of the first shaft portion 22f matches the position of the hole 31b, the first shaft portion 22f protrudes from the second columnar member 22 and fits into the hole 31b. When the position of the second shaft portion 22g matches the position of the hole 32b, the second shaft portion 22g protrudes from the second columnar member 22 and fits into the hole 32b. This allows the second columnar member 22 to be easily fixed.

[0099] As described above, in the elevator according to this embodiment, the first support member 31 has a hole 31b formed therein. The second support member 32 has a hole 32b formed therein. The second columnar member 22 has a through hole 22e formed therein. The first shaft portion 22f, the second shaft portion 22g, and the elastic body 30 are inserted into the through hole 22e. The elastic body 30 is sandwiched between the first shaft portion 22f and the second shaft portion 22g. A portion of the first shaft portion 22f protrudes from the through hole 22e and is inserted into the hole 31b of the first support member 31. A portion of the second shaft portion 22g protrudes from the through hole 22e and is inserted into the hole 32b of the second support member 32.

[0100] According to this configuration, the second pillar-shaped member 22 can be easily fixed to the first support member 31 and the second support member 32, and therefore the cable 13 can be easily fixed to the cable suspension device .
