[0010] The embodiments for carrying out the subject of the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are given the same reference numerals, and duplicated descriptions are appropriately simplified or omitted. Note that the subject of the present disclosure is not limited to the following embodiments, and any component of the embodiment may be modified or omitted within the scope of the gist of the present disclosure.
[0011] Embodiment 1 FIG. 1 is a side view of a rope clip 1 according to the first embodiment.
[0012] The rope clip 1 is used, for example, to secure a rope 3 that is folded back so as to curve along a thimble 2. The rope 3 is, for example, a wire rope. The rope 3 is, for example, the main rope of an elevator. The rope 3 may be a plurality of ropes that are stretched adjacent to each other in parallel. The rope 3 may be secured by a plurality of rope clips 1.
[0013] The rope clip 1 includes a U-bolt 4, a saddle 5, and two nuts 6. The U-bolt 4 is a bolt curved so as to be folded back into a U shape. Both ends of the U-bolt 4 are oriented in the same direction. The back of the U-bolt 4 is the curved part opposite both ends of the U-bolt 4. The saddle 5 is a seat part through which both ends of the U-bolt 4 are passed and which receives the rope 3. Each nut 6 is attached to each end of the U-bolt 4 passed through the saddle 5. The front of the saddle 5 is the part against which each nut 6 comes into contact. The rope clip 1 fixes the rope 3 sandwiched between the U-bolt 4 and the saddle 5 by tightening each nut 6. The rope clip 1 releases the fixation of the rope 3 sandwiched between the U-bolt 4 and the saddle 5 by loosening each nut 6.
[0014] When tightening or loosening the nut 6 of the rope clip 1, the rope clip 1 receives a torque that rotates in the tightening or loosening direction. Here, the tightening or loosening work of the nut 6 includes the work of tightening the nut 6 and the work of loosening the nut 6. The worker performing the tightening or loosening work tightens or loosens the nut 6 while suppressing the rotation of the rope clip 1 using an auxiliary tool 7 not shown in FIG. 1.
[0015] FIG. 2 is a top view of the assistive tool 7 according to the first embodiment.
[0016] The auxiliary tool 7 comprises a base 8, a first bar 9, and a second bar 10.
[0017] The base 8 includes a handle 11 and a support part 12. The handle 11 is, for example, long in one direction. The handle 11 is, for example, a polygonal column, a cylinder, or an elliptical cylinder. In this example, the longitudinal direction of the handle 11 is along the center line C of the handle 11. The longitudinal direction of the handle 11 is an example of a first direction. The support part 12 is a part to which the first bar 9 and the second bar 10 are attached. The support part 12 is, for example, a plate material made of iron or other metals, wood, resin, or other materials. The handle 11 and the support part 12 may be formed integrally, or one end of the first part 13 of the support part 12 may be the handle 11 of the base 8 as it is.
[0018] The first bar 9 and the second bar 10 are rod-shaped parts attached to the support 12. The first bar 9 and the second bar 10 are, for example, round bars whose cross sections in a plane perpendicular to the longitudinal direction are circular. In this example, the length and thickness of the first bar 9 and the second bar 10 are the same as each other. In this example, the length of the first bar 9 and the second bar 10 is shorter than the length from the back of the U-bolt 4 to the front of the saddle 5. The length of the first bar 9 and the second bar 10 may be the same as or longer than the length from the back of the U-bolt 4 to the front of the saddle 5. The length, thickness, and cross-sectional shape of the first bar 9 and the second bar 10 may be different from each other. The first bar 9 and the second bar 10 are attached to the base 8 so as to protrude from the ends on the opposite sides of the handle 11 to the same side in the direction perpendicular to the center line C of the handle 11. A direction perpendicular to the center line C of the handle 11, in which the longitudinal directions of the first bar 9 and the second bar 10 are oriented, is an example of the second direction. The first bar 9 and the second bar 10 are arranged at a distance from each other along the direction of the center line C of the handle 11. In this example, the second bar 10 is arranged at a position farther from the handle 11 than the first bar 9.
[0019] FIG. 3 is a front view of the assistive tool 7 according to the first embodiment.
[0020] The support part 12 has an L-shape having a first part 13 and a second part 14. The first part 13 is a part that follows the longitudinal direction of the handle 11. The handle 11 is disposed at one longitudinal end of the first part 13. The second part 14 is disposed at the other longitudinal end of the first part 13. The second part 14 is a part that faces in a direction perpendicular to the longitudinal direction of the first part 13. The longitudinal direction of the first part 13 and the longitudinal direction of the second part 14 are in-plane directions of the support part 12, which is a plate material, i.e., directions perpendicular to the thickness direction of the support part 12. The second part 14 has a long hole 15 that follows the longitudinal direction.
[0021] The first bar 9 is attached to the first portion 13 of the support portion 12 with its longitudinal direction facing the normal direction of the support portion 12, which is a plate material, i.e., the thickness direction of the support portion 12. The first bar 9 is attached to a position on the center line C of the handle 11. The second bar 10 is attached to the long hole 15 of the second portion 14 of the support portion 12 with its longitudinal direction facing the normal direction of the support portion 12, which is a plate material. The second bar 10 is disposed at a distance from the center line C of the handle 11 along the longitudinal direction of the second portion 14. The longitudinal direction of the second portion 14 is an example of a third direction perpendicular to the first and second directions.
[0022] FIG. 4 is a side view of the assisting tool 7 according to the first embodiment.
[0023] The first bar 9 is fixed to a first portion 13 of the support part 12 by, for example, a screw 16. The second bar 10 is fixed to a second portion 14 of the support part 12 by, for example, a wing bolt 17. The position at which the second bar 10 is fixed can be adjusted along a long hole 15 of the support part 12. The second bar 10 is disposed on one side along the longitudinal direction of the second portion 14 with respect to a plane P that is parallel to the longitudinal direction of the second bar 10 and includes the center line C of the handle 11.
[0024] Next, an example of the tightening operation of the rope clip 1 using the auxiliary tool 7 will be described with reference to Figs. FIG. 5 is a top view of the rope clip 1 in which a tightening operation is being performed using the auxiliary tool 7 according to the first embodiment. FIG. 6 is a side view of the rope clip 1 during tightening work using the auxiliary tool 7 according to the first embodiment. 7 to 9 are front views of the rope clip 1 in which a tightening operation is being performed using the auxiliary tool 7 according to the first embodiment.
[0025] As shown in Fig. 5, the worker clamps the rope 3 to be fixed between the removed U-bolt 4 and the saddle 5 of the rope clip 1. The worker orients both ends of the U-bolt 4 in the direction in which the two ropes 3 to be fixed are aligned. The worker provisionally tightens the nut 6 on the tip of the U-bolt 4 that has been passed through the saddle 5.
[0026] The worker holds the handle 11 of the auxiliary tool 7 and combines the first bar 9 and the second bar 10 with the rope clip 1 and the rope 3 from the U-bolt 4 side.
[0027] At this time, as shown in Figure 6, since the length of the first bar 9 and the second bar 10 is shorter than the length L from the back of the U-bolt 4 to the front of the saddle 5, the tips of the first bar 9 and the second bar 10 do not protrude from the front side of the saddle 5.
[0028] 7, the rope clip 1 is disposed between the first bar 9 and the second bar 10 in the longitudinal direction of the rope 3. The rope 3 is disposed between the first bar 9 and the second bar 10 in a direction perpendicular to the longitudinal direction of the rope 3. The handle 11 of the auxiliary tool 7 is disposed on the left side of the rope 3 when viewed from the front of the rope clip 1.
[0029] As shown in FIG. 8, the worker holds the handle 11 of the auxiliary tool 7 with one hand and tightens the nut 6 with a tool such as a wrench with the other hand. In this example, a clockwise torque is applied to the rope 3 when viewed from the front of the rope clip 1, so the worker holds the handle 11 of the auxiliary tool 7 downward to cancel the torque, as shown by the black arrow in FIG. 8. Since the sides of the first bar 9 and the second bar 10 come into contact with the rope 3, the torque applied to the rope 3 can be received by the auxiliary tool 7, and by holding the handle 11 of the auxiliary tool 7, the rotation of the rope clip 1 that fixes the rope 3 can be suppressed. At this time, the torque can be received by holding the handle 11 away from the position of the rope clip 1, so that the torque can be received with a small force, and the workability of tightening the rope clip 1 is improved.
[0030] Alternatively, the worker may combine the first bar 9 and second bar 10 of the auxiliary tool 7 with the rope clip 1 and rope 3 from the U-bolt 4 side, as shown in Fig. 9. At this time, the handle 11 of the auxiliary tool 7 is disposed on the right side of the rope 3 when viewed from the front of the rope clip 1. In this example, since a clockwise torque is applied to the rope 3 when viewed from the front of the rope clip 1, the worker presses the handle 11 of the auxiliary tool 7 upward to cancel out the torque, as shown by the black arrow in Fig. 9.
[0031] Next, an example of the loosening operation of the rope clip 1 using the auxiliary tool 7 will be described with reference to Figs. 10 and 11 are front views of the rope clip 1 during loosening work using the assisting tool 7 according to the first embodiment.
[0032] 10, a worker holds the handle 11 of the auxiliary tool 7 and combines the first bar 9 and the second bar 10 with the rope clip 1 and the rope 3 from the U-bolt 4 side. At this time, the rope clip 1 is placed between the first bar 9 and the second bar 10 in the longitudinal direction of the rope 3. The rope 3 is also placed between the first bar 9 and the second bar 10 in the direction perpendicular to the longitudinal direction of the rope 3. The handle 11 of the auxiliary tool 7 is also placed below the rope clip 1.
[0033] The worker holds the handle 11 of the auxiliary tool 7 with one hand and loosens the nut 6 with a tool such as a wrench with the other hand. In this example, since a counterclockwise torque is applied to the rope 3 when viewed from the front of the rope clip 1, the worker holds the handle 11 of the auxiliary tool 7 to the left to cancel the torque, as shown by the black arrow in FIG. 10. Since the sides of the first bar 9 and the second bar 10 come into contact with the rope 3, the torque applied to the rope 3 can be received by the auxiliary tool 7, and by holding the handle 11 of the auxiliary tool 7, the rotation of the rope clip 1 that fixes the rope 3 can be suppressed. At this time, since the torque can be received by holding the handle 11 away from the position of the rope clip 1, the torque can be received with a small force, and the workability of the rope clip 1 loosening work is improved.
[0034] 11, the worker may combine the first bar 9 and second bar 10 of the auxiliary tool 7 with the rope clip 1 and rope 3 from the U-bolt 4 side. At this time, the handle 11 of the auxiliary tool 7 is disposed on the upper side of the rope clip 1. In this example, since a counterclockwise torque is applied to the rope 3 when viewed from the front of the rope clip 1, the worker presses the handle 11 of the auxiliary tool 7 to the right to cancel the torque, as shown by the black arrow in FIG.
[0035] As described above, the auxiliary tool 7 for tightening and loosening the rope clip 1 according to the first embodiment includes a base 8, a first bar 9, and a second bar 10. The base 8 has a handle 11 at one end in the first direction. The center line C of the handle 11 is along the first direction. The first bar 9 protrudes in a second direction perpendicular to the first direction from an end of the base 8 opposite the handle 11 in the first direction. The second bar 10 protrudes in the second direction on the same side as the first bar 9 from an end of the base 8 opposite the handle 11 in the first direction. The second bar 10 is disposed on one side of a third direction perpendicular to a plane P parallel to the second direction including the center line C of the handle 11. With this configuration, the handle 11 away from the position of the rope clip 1 can be held down via the first bar 9 and the second bar 10 that contact the rope 3, and torque during tightening and loosening can be received. This allows torque to be received with a small force, improving the workability of tightening and loosening the rope clip 1. Also, since the first bar 9 and the second bar 10 contact the rope 3 at intervals along the longitudinal direction of the rope 3, the torque applied to the rope 3 can be received with a smaller force. Also, since no fixing tools larger than necessary are used, the workability of tightening and loosening the rope clip 1 is not likely to decrease even in cases where multiple ropes 3 are stretched adjacent to each other in a narrow work space, such as the main rope of an elevator.
[0036] In addition, a long hole 15 having a longitudinal direction in the third direction is provided in the base 8. The second bar 10 is attached to the long hole 15. This configuration makes it easy to adjust the position of the second bar 10 along the third direction. This makes it possible to apply the auxiliary tool 7 to various ropes 3 having different thicknesses. In addition, a recess may be provided on the edge of the long hole 15 in the base 8. The recess is provided at a plurality of positions along the longitudinal direction of the long hole 15 according to, for example, the thickness of the rope 3. Each recess is formed, for example, in a circular shape with a diameter larger than the diameter of the second bar 10 and a center on the long hole 15. Each recess is formed to a depth that allows the second bar 10 to move along the long hole 15 when, for example, the wing bolt 17 is loosened. In addition, each recess is formed to a depth that allows the second bar 10 to restrict movement along the long hole 15 when, for example, the wing bolt 17 is tightened to fix the second bar 10. This makes it difficult for the second bar 10 to move after its position has been adjusted, so that the position of the second bar 10 is less likely to shift while the assisting tool 7 is being used.
[0037] The base 8 is L-shaped and has a first portion 13 and a second portion 14. The first portion 13 has a handle 11 at one end. The first portion 13 is aligned in a first direction. The second portion 14 is aligned at an end of the first portion 13 opposite the handle 11 in the first direction. The second portion 14 is aligned in a third direction. The first bar 9 is attached to the first portion 13. The second bar 10 is attached to the second portion 14. This configuration makes it possible to make the base 8 lighter and more compact, making it easier to handle the auxiliary tool 7 during work. This improves the workability of tightening and loosening the rope clip 1.
[0038] Moreover, the first bar 9 and the second bar 10 are round bars with a circular cross section in a plane perpendicular to the longitudinal direction. This means that the side surfaces of the first bar 9 and the second bar 10 that come into contact with the rope 3 are curved surfaces without corners, which makes it possible to prevent damage to the rope 3.
[0039] In addition, the length of the first bar 9 and the second bar 10 is shorter than the length from the back of the U-bolt 4 to the front of the saddle 5. With this configuration, when the auxiliary tool 7 is combined with the rope clip 1 and the rope 3, the tips of the first bar 9 and the second bar 10 do not protrude from the front side of the saddle 5. Therefore, the first bar 9 and the second bar 10 are less likely to interfere with tools such as wrenches used to tighten and loosen the nut 6, so that the workability of tightening and loosening the rope clip 1 is less likely to decrease. Even if the tips of the first bar 9 and the second bar 10 protrude from the front side of the saddle 5, the worker can tighten and loosen the rope clip 1 using the auxiliary tool 7 by using, for example, a socket wrench.
[0040] The base 8 does not have to be an L-shaped plate material. The angle between the longitudinal direction of the first portion 13 of the base 8 and the longitudinal direction of the second portion 14 does not have to be a right angle. The base 8 may be, for example, a spatula-shaped plate material. The base 8 may be, for example, a bar bent into an L-shape or other shape. The first bar 9 may be attached to a position that is off the center line C of the handle 11. The auxiliary tool 7 may include one or more other bars that protrude in the second direction from the end of the base 8 on the opposite side of the handle 11 in the first direction on the same side as the first bar 9 and the second bar 10. The shape, length, and thickness of the other bars may be the same as those of the first bar 9 and the second bar 10.
