Detailed Implementation

[0043] Implementation method 1.

[0044] The elevator of Implementation Method 1 will be described. Figure 1 and Figure 2 This is a diagram showing the overall structure of the elevator according to this embodiment. Figure 1 and Figure 2 The vertical direction indicates the vertical direction. Figure 1 The structure of the elevator is shown when the car 11 is located above the shaft 10. Figure 2 The structure of the elevator is shown when the car 11 is located at the bottom of the shaft 10.

[0045] like Figure 1 and Figure 2 As shown, a car 11 is installed in the hoistway 10. The car 11 is configured to move up and down within the hoistway 10. The movement of the car 11 is guided by car guide rails (not shown). A control panel 12 is fixed in the hoistway 10. The control panel 12 is configured to control the movement of the car 11.

[0046] 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.

[0047] One end of cable 13 is connected to control panel 12 via cable suspension device 14. Cable suspension device 14 is fixed to shaft 10. Cable suspension device 14 can also be fixed to shaft 10 via other components such as those supporting control panel 12. Cable suspension device 14 is located below control panel 12. Cable 13 is suspended by cable suspension device 14.

[0048] 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 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.

[0049] The cable suspension device of this embodiment will now be described. The cable suspension device of this embodiment applies to both the cable suspension device 14 on the control panel 12 side and the cable suspension device 15 on the car 11 side. Hereinafter, the cable suspension device of this embodiment will be described using cable suspension device 14 as an example. Alternatively, the cable suspension device of this embodiment may also be applied to only one of cable suspension device 14 and cable suspension device 15.

[0050] Figure 3 This is a front view showing the structure of the cable suspension device for the elevator according to this embodiment. Figure 4 This is a side view showing the structure of the cable suspension device for the elevator according to this embodiment. Figure 3 and Figure 4 The vertical direction indicates the vertical direction. Figure 4 The structure of the cable suspension device 14 is shown when viewed along the respective extension directions of the first columnar member 21, the second columnar member 22, and the third columnar member 23.

[0051] like Figure 3 and Figure 4 As shown, the cable suspension device 14 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 cable 13 extends generally in the vertical direction.

[0052] The first columnar member 21, the second columnar member 22, and the third columnar member 23 extend in directions 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 each other. 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.

[0053] The second columnar member 22 is positioned below the first columnar member 21. The third columnar member 23 is positioned even 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 vertical 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 vertical distance between the first columnar member 21 and the second columnar member 22 is greater than or equal to 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 vertical distance between the second columnar member 22 and the third columnar member 23 is greater than or equal to the thickness of the cable 13.

[0054] The first columnar member 21, the second columnar member 22, and the third columnar member 23 each have a cylindrical or cylindrical shape. That is, the first columnar member 21, the second columnar member 22, and the third columnar member 23 each have a cylindrical outer peripheral surface. The first columnar member 21, the second columnar member 22, and the third columnar member 23 each have the same diameter and the same length in the extending direction. For example, the first columnar member 21, the second columnar member 22, and the third columnar member 23 are each formed from readily available and inexpensive steel pipes.

[0055] A cylindrical shaft portion 21a is formed at one end of the first columnar member 21 in its extending direction. The shaft portion 21a has a diameter smaller than the diameter of the first columnar member 21. The shaft portion 21a protrudes from the first columnar member 21 along its central axis. A cylindrical shaft portion 21b is formed at the other end of the first columnar member 21 in its extending direction. The shaft portion 21b has a diameter smaller than the diameter of the first columnar member 21. The shaft portion 21b protrudes from the first columnar member 21 along its central axis. The shaft portions 21a and 21b are fixed to the first columnar member 21.

[0056] Similarly, a cylindrical shaft portion 22a is formed at one end of the second columnar member 22 in its extending direction. The shaft portion 22a has a diameter smaller than the diameter of the second columnar member 22. The shaft portion 22a protrudes from the second columnar member 22 along its central axis. A cylindrical shaft portion 22b is formed at the other end of the second columnar member 22 in its extending direction. The shaft portion 22b has a diameter smaller than the diameter of the second columnar member 22. The shaft portion 22b protrudes from the second columnar member 22 along its central axis. Both shaft portions 22a and 22b are fixed to the second columnar member 22.

[0057] The first support member 31 and the second support member 32 each have a rectangular flat plate shape that is longer in the vertical direction. The first support member 31 and the second support member 32 are arranged opposite each other with respect to 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 the extension direction 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 the extension direction of each of the first columnar member 21, the second columnar member 22, and the third columnar member 23.

[0058] Holes 31a and 31b are formed in the first support member 31. Holes 32a and 32b are formed in the second support member 32. Holes 32a and 31a are opposite each other. Holes 32b and 31b are opposite each other. Holes 31a, 31b, 32a, and 32b are all circular in shape.

[0059] Shaft 21a is rotatably inserted into hole 31a of first support member 31. Shaft 21b is rotatably inserted into hole 32a of second support member 32. Thus, first columnar member 21 is supported by first support member 31 and second support member 32 so that it can rotate freely about the central axis of first columnar member 21.

[0060] The shaft portion 22a is rotatably inserted into the hole 31b of the first support member 31. The shaft portion 22b is rotatably inserted into the hole 32b of the second support member 32. Thus, the second columnar member 22 is supported by the first support member 31 and the second support member 32, allowing it to rotate freely about its central axis. When fixing the cable 13 to the cable suspension device 14, the second columnar member 22 is installed by the cable 13 installation personnel. That is, the second columnar member 22 can be subsequently installed on the first support member 31 and the second support member 32. The second columnar member 22 can also be detached from the first support member 31 and the second support member 32.

[0061] 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. Thus, the third columnar member 23 is supported by the first support member 31 and the second support member 32 to prevent rotation. 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 to prevent rotation.

[0062] Cable 13 is a flat cable with a flat cross-sectional shape. Cable 13 has a first surface 13a and a second surface 13b. Both the first surface 13a and the second surface 13b are surfaces along the width direction of cable 13. The second surface 13b is the surface opposite to the first surface. Cable 13 can also be a circular cable with a circular cross-sectional shape.

[0063] exist Figure 3 In the shown front view, 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 cable 13. The outer peripheral surface of the second columnar member 22 is in contact with the second surface 13b of cable 13. Cable 13 is pressed between the first columnar member 21 and the third columnar member 23 by the second columnar member 22. 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.

[0064] The pressing force of each of the first columnar component 21, the second columnar component 22, and the third columnar component 23 applies to the cable 13. The direction of the pressing force of the second columnar component 22 is... Figure 4 The pressing direction of the first columnar component 21 and the third columnar component 23 is opposite to the pressing direction of the second columnar component 22. Figure 4 To the left of the middle. Cable 13 is bent in such a way that it protrudes in the direction of the pressure applied to the second columnar member 22.

[0065] Here, the contact portion where the first columnar member 21 contacts the cable 13 is designated as contact portion 41. The contact portion where the second columnar member 22 contacts the cable 13 is designated as contact portion 42. The contact portion where the third columnar member 23 contacts the cable 13 is designated as contact portion 43. The straight line passing through contact portions 41 and 43 is designated as straight line 44. In a side view viewed along the extending direction of the second columnar member 22, contact portion 42 is located closer to the side towards which the pressing force of the second columnar member 22 acting on the cable 13 is directed than straight line 44.

[0066] Due to these pressing forces, frictional forces are generated between the first columnar member 21, the second columnar member 22, and the third columnar member and the cable 13. The cable suspension device 14 utilizes these frictional forces to support the vertical load of the cable 13.

[0067] Next, the method for fixing cable 13 to cable suspension device 14 will be described. Figure 5 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 5As shown, the second columnar component 22 has not yet been installed in the cable suspension device 14 before the fixed cable 13.

[0068] First, cable 13 is clamped between the first columnar member 21 and 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 cable 13. The second columnar member 22 is located on the second surface 13b side of cable 13.

[0069] Next, the second columnar member 22 and the cable 13 are pressed together between the first columnar member 21 and the third columnar member 23. In this embodiment, since rotation of the first columnar member 21 and the second columnar member 22 is permitted, the second columnar member 22 and the cable 13 can be pressed between the first columnar member 21 and the third columnar member 23 with less force.

[0070] 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 inserted into the hole 31b of the first support member 31, and the shaft portion 22b is inserted into the hole 32b of the second support member 32. Thus, the second columnar member 22 is supported by the first support member 31 and the second support member 32. Through the above steps, as... Figure 3 and Figure 4 As shown in the diagram, cable 13 is fixed to cable suspension device 14.

[0071] As described above, the elevator of this embodiment includes a car 11, a control panel 12, a cable 13, a cable suspension device 14, and a cable suspension device 15. The car 11 is configured to move up and down in a 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.

[0072] Cable suspension devices 14 and 15 each have 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 positioned below the first columnar member 21. The third columnar member 23 is positioned below 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. The first columnar member 21, the second columnar member 22, and the third columnar member 23 extend in directions intersecting the vertical direction.

[0073] The first columnar member 21 and the third columnar member 23 contact the first surface 13a of the cable 13. The second columnar member 22 contacts the second surface 13b of the cable 13, which is the side opposite to the first surface 13a. The cable 13 bends along each of the columnar members 21, 22, and 23. The pressing force of the second columnar member 22 acts on the cable 13. The straight line through the contact portion 41 where the first columnar member 21 contacts the cable 13 and the contact portion 43 where the third columnar member 23 contacts the cable 13 is defined as a straight line 44. When viewed along the extending direction of the second columnar member 22, the contact portion 42 where the second columnar member 22 contacts the cable 13 is located further away from the side towards which the pressing force of the second columnar member 22 is directed than the straight line 44.

[0074] According to this structure, by pressing the cable 13 between the first columnar member 21 and the third columnar member 23 using the second columnar member 22, the cable 13 can be fixed to the cable suspension device 14 and the cable suspension device 15 respectively. Therefore, the fixing operation of the cable 13 to the cable suspension device 14 and the cable suspension device 15 can be easily performed.

[0075] In the elevator of this embodiment, one or two of the first columnar member 21, the second columnar member 22, and the third columnar member 23 are rotatably supported by the first support member 31 and the second support member 32. According to this structure, the second columnar member 22 and the cable 13 can be pressed between the first columnar member 21 and the third columnar member 23 with less force. Therefore, it is easier to perform the fixing operations of the cable 13 to the cable suspension device 14 and the cable suspension device 15 respectively. Since at least one of the first columnar member 21, the second columnar member 22, and the third columnar member 23 does not rotate, the vertical load of the cable 13 can be supported by the cable suspension device.

[0076] In the elevator of this embodiment, the first columnar member 21, the second columnar member 22, and the third columnar member 23 each have a cylindrical outer peripheral surface. This structure can suppress damage to the cable 13 due to contact with each of the columnar members 21, 22, and 23. Furthermore, this structure allows the columnar members 21, 22, and 23 to be formed using steel pipes, thus increasing the ease of obtaining components for the cable suspension device and reducing the manufacturing cost of the cable suspension device and the elevator including it.

[0077] Implementation method 2.

[0078] The elevator of Implementation Method 2 will be described. Figure 6 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 6 As shown, no shaft portion is formed at 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. Thus, the first columnar member 21 and the third columnar member 23 are similarly supported by the first support member 31 and the second support member 32 to prevent rotation. Other structures are the same as in Embodiment 1.

[0079] Figure 7 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 7 As shown, in this embodiment, the cable 13 is fixed to the cable suspension device 14 by the same steps as in embodiment 1.

[0080] In this embodiment, since the first columnar member 21 and the third columnar member 23 do not rotate, the cable 13 can be more securely fixed to the cable suspension device 14 than in embodiment 1.

[0081] Implementation method 3.

[0082] The elevator of Implementation Method 3 will be described. Figure 8 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 8 As shown, the shaft portion 22b of the second columnar member 22 has a quadrangular prism shape. Although not shown, the shaft portion 22a of the second columnar member 22 also has a quadrangular prism shape. The holes 31b of the first support member 31 and 32b of the second support member 32 are both formed into quadrilaterals. Thus, the second columnar member 22 is supported by the first support member 31 and the second support member 32 to prevent rotation. Other structures are the same as in Embodiment 2.

[0083] Figure 9 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 9 As shown, in this embodiment, the cable 13 is fixed to the cable suspension device 14 by the same steps as in embodiment 1.

[0084] In this embodiment, in addition to the first columnar member 21 and the third columnar member 23 not rotating, the second columnar member 22 also does not rotate, so the cable 13 can be more securely fixed to the cable suspension device 14 than in embodiment 2.

[0085] Implementation method 4.

[0086] The elevator of Implementation Method 4 will be described. Figure 10 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 10 As shown, the parallel orientation of the first columnar member 21, the second columnar member 22, and the third columnar member 23 is inclined relative to the vertical direction. Thus, the cable suspension device 14 can also be configured such that the parallel orientation of the first columnar member 21, the second columnar member 22, and the third columnar member 23 is inclined relative to the vertical direction.

[0087] Implementation method 5.

[0088] The elevator of Implementation Method 5 will be described. Figure 11 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 11 As shown, no shaft portion is 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. Thus, the second columnar member 22 and the third columnar member 23 are similarly supported by the first support member 31 and the second support member 32 to prevent rotation.

[0089] The first columnar member 21 is supported by the first support member 31 and the second support member 32, allowing it to rotate freely. When fixing the cable 13 to the cable suspension device 14, the first columnar member 21 is installed by the cable 13 installation personnel. That is, the first columnar member 21 can be subsequently installed on the first support member 31 and the second support member 32. The first columnar member 21 can also be detached from the first support member 31 and the second support member 32. Other structures are the same as in Embodiment 1.

[0090] Figure 12 and Figure 13 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 12 As shown, the first columnar component 21 has not yet been installed in the cable suspension device 14 before the fixed cable 13.

[0091] First, such as Figure 12 As shown, 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 cable 13. The second columnar member 22 is located on the second surface 13b side of cable 13.

[0092] Next, the cable suspension device 14 is centered on an axis parallel to the extending direction of the second columnar member 22, and directed towards... Figure 12 The thick arrow rotates in the direction of the arrowhead. Therefore, as... Figure 13As shown, cable 13 is bent along the outer peripheral surfaces of the second columnar member 22 and the third columnar member 23. Next, the first columnar member 21 is installed. Thus, as... Figure 11 The cable 13 is secured to the cable suspension device 14 in the manner shown.

[0093] According to this embodiment, it is not necessary to press the second columnar member 22 together with the cable 13 into the space between the first columnar member 21 and the third columnar member 23. Therefore, it is possible to use less force to fix the cable 13 to the cable suspension device 14.

[0094] In this embodiment, the columnar member subsequently installed on the first support member 31 and the second support member 32 is the first columnar member 21, but the columnar member subsequently installed on the first support member 31 and the second support member 32 may also be the third columnar member 23. That is, in this embodiment, the first columnar member 21 or the third columnar member 23 can be subsequently installed on the first support member 31 and the second support member 32.

[0095] Implementation method 6.

[0096] The elevator of Implementation Method 6 will be described. Figure 14 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 14 As shown, a cut 33 is formed in the second support member 32. The cut 33 has an open end 33a. The open end 33a is formed in the end face 32c of the second support member 32, on the side opposite to the direction of the pressing force acting on the second columnar member 22 of the cable 13. The cut 33 extends obliquely downward from the open end 33a. The shaft portion 22b of the second columnar member 22 is inserted into the cut 33. The shaft portion 22b is located below the open end 33a of the cut 33. Other structures are the same as in Embodiment 3.

[0097] In this embodiment, a cutout 33 is formed in the second support member 32, but the cutout may also be formed in the first support member 31, or in both the first support member 31 and the second support member 32.

[0098] Figure 15 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 15 As shown, the second columnar member 22 has not yet been installed in the cable suspension device 14 before the cable 13 is fixed. When the second columnar member 22 is pressed together with the cable 13 between the first columnar member 21 and the third columnar member 23, the shaft portion 22b is inserted from the opening end 33a into the cutout 33 and guided by the cutout 33.

[0099] As explained above, in the elevator of this embodiment, a shaft portion 22b protruding from the second columnar member 22 is formed at the extending end of the second columnar member 22. A cutout 33 is formed in the second support member 32. The cutout 33 has an open end portion 33a on the end face 32c opposite to the direction of the pressing force acting on the second columnar member 22 of the cable 13. The cutout 33 extends obliquely downward from the open end portion 33a. The shaft portion 22b is inserted into the cutout 33. The shaft portion 22b is located below the open end portion 33a.

[0100] According to this structure, the second columnar member 22 is not easily detached from the cable suspension device 14, thus simplifying the mechanism for holding the second columnar member 22 in the cable suspension device 14.

[0101] Furthermore, according to this structure, since the shaft portion 22b is guided by the cutout 33, it is easy to press the second columnar member 22 between the first columnar member 21 and the third columnar member 23.

[0102] Implementation method 7.

[0103] The elevator of Implementation Method 7 will be described. Figure 16 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 16 As shown, a protrusion 26 is formed on the outer peripheral surface of the second columnar member 22. The protrusion 26 functions as a friction-increasing part to increase the frictional force generated between the second columnar member 22 and the cable 13. Other structures are the same as in Embodiment 2.

[0104] Figure 17 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 17 As shown, in this embodiment, the cable 13 is fixed to the cable suspension device 14 using the same steps as in Embodiment 1. In this embodiment, the frictional force generated between the second columnar member 22 and the cable 13 is increased, thus allowing the cable 13 to be more securely fixed to the cable suspension device 14.

[0105] In this embodiment, the uneven surface 26 is formed as a friction-increasing part, but a rubber part can also be wound around the outer peripheral surface of the second columnar member 22 as a friction-increasing part. Furthermore, in this embodiment, a friction-increasing part is formed on the outer peripheral surface of the second columnar member 22, but the same effect can be obtained as long as a friction-increasing part is formed on the outer peripheral surface of any one of the columnar members 21, 22, and 23.

[0106] As explained above, in the elevator of this embodiment, a friction-enhancing portion is formed on at least one of the first columnar member 21, the second columnar member 22, and the third columnar member 23. According to this structure, the frictional force generated between at least one of the first columnar member 21, the second columnar member 22, and the third columnar member 23 and the cable 13 can be increased, thus allowing the cable 13 to be more securely fixed to the cable suspension device 14.

[0107] Implementation method 8.

[0108] The elevator of Implementation Method 8 will be described. Figure 18 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 18 As shown, the first columnar member 21, the second columnar member 22, and the third columnar member 23 each have a partially cylindrical shape lacking a portion of the cylinder. In each of the first columnar member 21, the second columnar member 22, and the third columnar member 23, the outer peripheral surface of the contact portion that contacts the cable 13 is formed into a cylindrical surface. Other structures are the same as in Embodiment 2.

[0109] Implementation method 9.

[0110] The elevator of Implementation Method 9 will be described. Figure 19 This is a side view showing the structure of the elevator cable suspension device according to this embodiment. Figure 19 As shown, the first columnar member 21 and the third columnar member 23 are in a twisted position. The first columnar member 21 and the second columnar member 22 are in a twisted position. The third columnar member 23 and the second columnar member 22 are in a twisted position. Thus, the first columnar member 21, the second columnar member 22, and the third columnar member 23 can also be arranged without being parallel to each other.

[0111] Implementation method 10.

[0112] The elevator of Implementation Method 10 will be described. Figure 20 This is a side view showing the structure of the cable suspension device for the elevator according to this embodiment. Figure 21 This is a perspective view showing the structure of the second columnar member in the cable suspension device of the elevator according to this embodiment. Figure 22 This is an exploded perspective view showing the structure of the second columnar component in the cable suspension device of the elevator according to this embodiment.

[0113] like Figures 20 to 22 As shown, a through hole 22e is formed in the second columnar member 22. The through hole 22e extends through the second columnar member 22 along its extending direction. The through hole 22e is formed on the central axis of the second columnar member 22.

[0114] A shaft component 22d, which is different from the second columnar component 22, is inserted into the through hole 22e. The shaft component 22d is used to fix the second columnar component 22 to the first support component 31 and the second support component 32. The shaft component 22d has a cylindrical shape. The axial length of the shaft component 22d is longer than the extension length of the second columnar component 22.

[0115] The hole 31b of the first support member 31 is a through hole that passes through the first support member 31. The hole 32b of the second support member 32 is a through hole that passes through the second support member 32. The shaft member 22d passes through 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. Cotter pins 27 are installed at both ends of the shaft member 22d. The cotter pins 27 are used to prevent the shaft member 22d from dislodging from the first support member 31, the second columnar member 22, and the second support member 32. Other structures are the same as in Embodiment 2.

[0116] Figure 23 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 23 As shown, when fixing cable 13 to cable suspension device 14, the second columnar member 22 is pressed together with cable 13 between the first columnar member 21 and the third columnar member 23. Then, the position of through hole 22e is aligned with the positions of hole 31b of the first support member 31 and hole 32b of the second support member 32. In this state, shaft member 22d is aligned with through hole 31b, through hole 22e, and hole 32b. Thus, the second columnar member 22 is fixed to the first support member 31 and the second support member 32.

[0117] Then, cotter pins 27, etc., are installed at both ends of the shaft member 22d. This prevents the shaft member 22d from coming out and also prevents its rotation. When the rotation of the shaft member 22d relative to the second columnar member 22 is restricted, preventing the rotation of the shaft member 22d also prevents the rotation of the second columnar member 22.

[0118] As explained above, in the elevator of this embodiment, a hole 31b, serving as a through hole, is formed in the first support member 31. A hole 32b, also serving as a through hole, is formed in the second support member 32. A through hole 22e is formed in the second columnar member 22. The cable suspension device 14 also includes 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 columnar member 22.

[0119] According to this structure, when the second columnar member 22 is pressed between the first columnar member 21 and the third columnar member 23, interference between the shaft member 22d and the respective support members of the first support member 31 and the second support member 32 can be prevented. 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 using the shaft member 22d.

[0120] Implementation method 11.

[0121] The elevator of Implementation Method 11 will be described. Figure 24 This is a perspective view showing the structure of the cable suspension device for the elevator according to this embodiment. Figure 25 This is an exploded perspective view showing the structure of the elevator cable suspension device according to this embodiment. Figure 24 and Figure 25 The illustrations of the first columnar component 21 and the third columnar component 23 are omitted.

[0122] like Figure 24 and Figure 25 As shown, the first fastening member 28a and the second fastening member 28b are used as shaft members for fixing the second columnar member 22. Bolts or the like are used for the first fastening member 28a and the second fastening member 28b, respectively.

[0123] The hole 31b of the first support member 31 is a through hole that passes through the first support member 31. The hole 32b of the second support member 32 is a through hole that passes through the second support member 32. The first fastening member 28a fastens one end of the first support member 31 and the second columnar member 22 through the hole 31b. The second fastening member 28b fastens the other end of the second support member 32 and the second columnar member 22 through the hole 32b. Other structures are the same as in embodiment 10.

[0124] When fixing the cable 13 to the cable suspension device 14, after pressing the second columnar member 22 between the first columnar member 21 and the third columnar member 23, the first support member 31 and the second columnar member 22 are fastened by the first fastening member 28a, and the second support member 32 and the second columnar member 22 are fastened by the second fastening member 28b.

[0125] As explained above, in the elevator of this embodiment, a hole 31b, serving as a through hole, is formed in the first support member 31. A hole 32b, also serving as a through hole, is formed in the second support member 32. The cable suspension device 14 further includes a first fastening member 28a and a second fastening member 28b. The first fastening member 28a fastens one end of the first support member 31 and the second columnar member 22 through the hole 31b of the first support member 31. The second fastening member 28b fastens the other end of the second support member 32 and the second columnar member 22 through the hole 32b of the second support member 32.

[0126] According to this structure, when the second columnar member 22 is pressed between the first columnar member 21 and the third columnar member 23, interference between the first fastening member 28a and the first support member 31, as well as interference between the second fastening member 28b and the second support member 32, can be prevented. 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 using the first fastening member 28a and the second fastening member 28b.

[0127] Implementation method 12.

[0128] The elevator of Implementation Method 12 will be described. Figure 26 This is a cross-sectional view showing the structure of the cable suspension device for the elevator according to this embodiment.

[0129] like Figure 26 As shown, a cable-like component 29 is used for the shaft component used to fix the second columnar component 22. A through hole 22e is formed in the second columnar component 22. The hole 32b of the second support component 32 is a through hole that passes through the second support component 32. The cable-like component 29 passes through the through hole 22e of the second columnar component 22 and the hole 32b of the second support component 32. One end of the cable-like component 29 is fixed to the first support component 31. The other end of the cable-like component 29 is led out from the hole 32b of the second support component 32 to the outside of the cable suspension device 14. Other structures are the same as in Embodiment 1, etc.

[0130] Figure 27 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 27 As shown, when fixing cable 13 to cable suspension device 14, the cable-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, and the other end of the cable-like member 29 is led out to the outside of cable suspension device 14. When the other end of the cable-like member 29 is pulled in this state, the second columnar member 22 and cable 13 are pressed together between the first columnar member 21 and the third columnar member 23. Thus, cable 13 can be easily fixed to cable suspension device 14.

[0131] As explained above, in the elevator of this embodiment, the cable suspension device 14 also includes a cable-like component 29. The cable-like component 29 is fixed to the first support component 31. A hole 32b, serving as a through hole, is formed in the second support component 32. A through hole 22e is formed in the second columnar component 22. The cable-like component 29 passes through the through hole 22e of the second columnar component 22 and the hole 32b of the second support component 32.

[0132] According to this structure, by pulling the other end of the cable-like component 29, the second columnar component 22 and the cable 13 can be easily pressed between the first columnar component 21 and the third columnar component 23. Therefore, the cable 13 can be easily fixed to the cable suspension device 14.

[0133] Implementation method 13.

[0134] The elevator of Implementation Method 13 will be described. Figure 28 This is a cross-sectional view showing the structure of the cable suspension device for the elevator according to this embodiment. Figure 28 The direction of the pressing force applied to the second columnar member 22 of the cable 13 is indicated above.

[0135] like Figure 28 As shown, the cable suspension device 14 has a first lifting bolt 34a and a second lifting bolt 34b. The first support member 31 has a bolt support portion 31d with an internal thread. The first lifting bolt 34a passes through the internal thread of the bolt support portion 31d. Thus, the first lifting bolt 34a is supported on the first support member 31. The front end of the first lifting bolt 34a is pressed against the outer peripheral surface of one end of the second columnar member 22.

[0136] The second support member 32 has a bolt support portion 32d with an internal thread. The second jacking bolt 34b passes through the internal thread of the bolt support portion 32d. Thus, the second jacking bolt 34b is supported on the second support member 32. The front end of the second jacking bolt 34b is pressed against the outer peripheral surface of the other end of the second columnar member 22.

[0137] One end of the second columnar member 22 is pressed by the first lifting bolt 34a in the direction of the pressing force acting on the second columnar member 22 of the cable 13. The other end of the second columnar member 22 is pressed by the second lifting bolt 34b in the same direction. This maintains the position of the second columnar member 22 in the direction of the pressing force. Other structures are the same as in Embodiment 1, etc.

[0138] Figure 29 This diagram illustrates a method for securing cables to the cable suspension device of the elevator according to this embodiment. Figure 29As shown, when fixing the cable 13 to the cable suspension device 14, the second columnar member 22 and the cable 13 are pressed together between the first columnar member 21 and the third columnar member 23 using the first lifting bolt 34a and the second lifting bolt 34b. This allows the cable 13 to be easily fixed to the cable suspension device 14.

[0139] As explained above, in the elevator of this embodiment, the cable suspension device 14 further includes a first lifting bolt 34a and a second lifting bolt 34b. The first lifting bolt 34a is supported on a first support member 31. The second lifting bolt 34b is supported on a second support member 32. One end of the second columnar member 22 is pressed by the first lifting bolt 34a in the direction of the pressing force acting on the second columnar member 22 of the cable 13. The other end of the second columnar member 22 is pressed by the second lifting bolt 34b in the direction of the pressing force acting on the second columnar member 22 of the cable 13.

[0140] According to this structure, by using the first lifting bolt 34a and the second lifting bolt 34b, the second columnar member 22 and the cable 13 can be easily pressed into the space 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.

[0141] Implementation method 14.

[0142] The elevator of Implementation Method 14 will be described. Figure 30 This is a front view showing the structure of the cable suspension device for the elevator according to this embodiment. Figure 31 and Figure 32 This is a cross-sectional view showing the structure of the second columnar member in the cable suspension device of the elevator according to this embodiment.

[0143] like Figures 30 to 32 As shown, a through hole 22e is formed in the second columnar member 22. The through hole 22e extends through the second columnar member 22 along its extending direction. The through hole 22e is formed on the central axis of the second columnar member 22.

[0144] 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 held 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 configured to move along the through hole 22e. The elastic body 30 applies a force to the first shaft portion 22f and the second shaft portion 22g in a direction protruding axially outward from the through hole 22e. Inside the through hole 22e, a mechanism is provided as needed to limit the movement range of the first shaft portion 22f and the second shaft portion 22g.

[0145] like Figure 31 As shown, a portion of the first shaft portion 22f protrudes from one axial end face 22h of the second columnar member 22 and is embedded in 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 embedded in the hole 32b of the second support member 32. When a force from the axially outer side is applied to the first shaft portion 22f and the second shaft portion 22g to overcome the restoring force of the elastic body 30, the first shaft portion 22f and the second shaft portion 22g... Figure 32 It is housed inside the through hole 22e as shown.

[0146] When fixing cable 13 to cable suspension device 14, the second columnar member 22 is pressed together with cable 13 between the first columnar member 21 and the third columnar member 23. At this time, an axially outward force is applied to the first shaft portion 22f and the second shaft portion 22g, which are then 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 aligns with the position of the hole 31b, the first shaft portion 22f protrudes from the second columnar member 22 and is embedded in the hole 31b. When the position of the second shaft portion 22g aligns with the position of the hole 32b, the second shaft portion 22g protrudes from the second columnar member 22 and is embedded in the hole 32b. This allows for easy fixation of the second columnar member 22.

[0147] As explained above, in the elevator of this embodiment, a hole 31b is formed in the first support member 31. A hole 32b is formed in the second support member 32. A through hole 22e is formed in the second columnar member 22. 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 held 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.

[0148] According to this structure, the second columnar member 22 can be easily fixed to the first support member 31 and the second support member 32, and thus the cable 13 can be easily fixed to the cable suspension device 14.

[0149] The above-described implementation methods can be combined with each other.
