In Fig. 17, the first base plate 41a and the second base plate 41b are omitted in order to make it easier to understand the internal structure of the base structure 4. Fig. 18 is a schematic diagram showing a linear material placement tool 1 in a fifth modified example of the first embodiment. Fig. 19 is a schematic cross-sectional view showing a linear material placement tool 1 in a sixth modified example of the first embodiment. Fig. 20 is a schematic diagram showing a linear material placement tool 1 in a seventh modified example of the first embodiment.

[0012] 1, the wire placement tool 1 in the first embodiment includes a first part 11, a first support member 21, and a second part 12. The wire placement tool 1 also includes an assembly AS including the first part 11, the second part 12, and the first support member 21.

[0013] To the first component 11, a first portion W1 of the wire W (more specifically, a first end portion Wa of the wire W) is attached.

[0014] The first support member 21 is capable of supporting the first part 11. In the example shown in FIG. 1, the first support member 21 directly supports gravity acting on the first part 11. Alternatively, the first support member 21 may indirectly support gravity acting on the first part 11. In the example shown in FIG. 6 (see the upper view in FIG. 6), the first support member 21 indirectly supports gravity acting on the first part 11 via the linear material W.

[0015] As illustrated in Fig. 1, the second part 12 is separable from the first part 11. Also, as illustrated in Fig. 3 (see the lower drawing in Fig. 3), the second part 12 is capable of receiving the first part 11.

[0016] 1 , the assembly AS includes a first part 11, a second part 12, and a first support member 21. Additionally, the assembly AS may include a second support member 31 that supports the second part 12. The assembly AS may also include a base structure 4 that supports the first support member 21. The base structure 4 may support the second support member 31 in addition to the first support member 21.

[0017] In the example shown in Figure 1 (see the upper view in Figure 1), the assembly AS is in a first state in which a first passage opening OP1 through which a standing tree TR can pass is formed between the first part 11 and the second part 12.

[0018] When the assembly AS is in the first state, the first part 11 and the second part 12 are separated from each other. Furthermore, when the assembly AS is in the first state, the distance L1 between the first part 11 and the second part 12 is relatively large. Therefore, the tree TR can be easily placed inside the assembly AS through the first passage opening OP1 formed between the first part 11 and the second part 12. When the assembly AS is in the first state, the distance L1 between the first part 11 and the second part 12 may be, for example, 25 cm or more, 35 cm or more, or 45 cm or more.

[0019] In the example shown in FIG. 3, the assembly AS is in a second state in which the first part 11 can be delivered to the second part 12. The second state is a state in which the interval between the first support member 21 and the second part 12 is reduced so that the first part 11 can be delivered to the second part 12. More specifically, the second state is a state in which the distance between the first support member 21 and the second part 12 is set to a distance in which the first part 11 can be delivered from the first support member 21 to the second part 12. In the example shown in FIG. 3, when the assembly AS is in the second state, the first part 11 is delivered from the first support member 21 to the second part 12 (in other words, when the assembly AS is in the second state, the second part 12 receives the first part 11 from the first support member 21). By this delivery (or by this reception), a complex 10 of the first part 11 and the second part 12 is formed.

[0020] In the example shown in FIG. 4 (see the lower diagram in FIG. 4), the assembly AS is in the third state. More specifically, the third state is a state in which a second passage opening OP2 through which the standing tree TR can pass is formed between the complex 10 of the first part 11 and the second part 12 and the first support member 21. When the assembly AS is in the third state, a linear material W is hung between the first part 11 and the first support member 21. In the example shown in FIG. 4 (see the lower diagram in FIG. 4), when the assembly AS is in the third state, a second passage opening OP2 is formed between the first part 11 constituting a part of the complex 10 and the first support member 21, and a linear material W is hung between the first part 11 constituting a part of the complex 10 and the first support member 21.

[0021] In the first embodiment, the linear material placement tool 1 can change the state of the assembly AS between (A) a first state in which a first passage opening OP1 through which a standing tree TR can pass is formed between the first part 11 and the second part 12, (B) a second state in which the distance between the first support member 21 and the second part 12 is reduced, and (C) a third state in which a second passage opening OP2 through which a standing tree TR can pass is formed between the complex 10 of the first part 11 and the second part 12 and the first support member 21.

[0022] In the linear material placement tool 1 of the first embodiment, the state of the assembly AS can be switched from a first state, via a second state, to a third state, thereby enabling linear material W to be quickly placed around a standing tree TR.

[0023] More specifically, as illustrated in FIG. 1, when the first part 11 and the second part 12 are in a separated state (in other words, when the assembly AS is in the above-mentioned first state), the tree TR can be easily placed inside the assembly AS through the first passage opening OP1 formed between the first part 11 and the second part 12. In other words, the tree TR can be easily placed inside the assembly AS by moving the assembly AS so that the first passage opening OP1 formed between the first part 11 and the second part 12 crosses the tree TR. Also, as illustrated in FIG. 3, the assembly AS can transfer the first part 11 from the first support member 21 to the second part 12. By transferring the first part 11 to the second part 12, the first part 11 and the first portion W1 of the linear material W attached to the first part 11 are prevented from falling to an undesirable position (for example, a position where they are caught on a branch of the tree TR). Furthermore, as illustrated in Fig. 4, after the composite 10 of the first part 11 and the second part 12 is formed, the composite 10 is separated from the first support member 21, thereby forming a second passage opening OP2 through which the tree TR can pass between the composite 10 and the first support member 21. A linear material W is hung across the second passage opening OP2. Therefore, by moving the assembly AS so that the second passage opening OP2 crosses the tree TR, the linear material W can be easily arranged around the standing tree TR (see Fig. 5).

[0024] (Optional configuration) Next, optional additional configurations that can be adopted in the wire placement tool 1 in the first embodiment will be described with reference to FIGS.

[0025] (Second support member 31) 1 , the assembly AS includes a second support member 31 that supports the second part 12. Furthermore, when the assembly AS is in the above-mentioned first state, the first part 11 is supported by the first support member 21, and the second part 12 is supported by the second support member 31.

[0026] As illustrated in Fig. 4 (see the lower diagram in Fig. 4), when the assembly AS is in the above-mentioned third state, the complex 10 of the first part 11 and the second part 12 is supported by the second support member 31. In other words, the second support member 31 supports both the first part 11 and the second part 12. In the example shown in Fig. 5, with both the first part 11 and the second part 12 supported by the second support member 31, the assembly AS is moved relative to the standing tree TR, whereby the linear material W is quickly positioned around the standing tree TR.

[0027] (Arm M) At least one of the first support member 21 and the second support member 31 may include an arm M. The arm M is pivotable so that the distance between the first part 11 supported by the first support member 21 and the second part 12 supported by the second support member 31 is reduced (see FIG. 2).

[0028] When the distance between the first part 11 and the second part 12 is reduced by the swinging of the arm M, the transfer of the first part 11 from the first support member 21 to the second part 12 can be achieved with a simple configuration.

[0029] 7, the arm M may be extendable so that the distance between the first part 11 supported by the first support member 21 and the second part 12 supported by the second support member 31 is reduced. In other words, the length of the arm M may be changeable so that the distance between the first part 11 supported by the first support member 21 and the second part 12 supported by the second support member 31 is reduced.

[0030] In the example shown in FIG. 7, the arm M includes a first arm M1 and a second arm M2, and the arm M is extended (in other words, the length of the arm M is changed) by the relative movement of the first arm M1 with respect to the second arm M2. More specifically, when the gear G rotates, the first arm M1 meshing with the gear G moves relative to the second arm M2. In this way, the arm M is extended. In the example shown in FIG. 7, each of the first arm M1 and the second arm M2 is formed of an arc-shaped body. Alternatively, each of the first arm M1 and the second arm M2 may be formed of a straight rod-shaped body. In the example shown in FIG. 7, the gear G may be rotated using the power of a motor or may be rotated using human power.

[0031] In the example shown in FIG. 8, the arm M is a tubular arm 21m. It is preferable that the linear material W is arranged along the internal passage of the tubular arm 21m. In this case, the linear material W is protected by the tubular arm 21m. Also, when the assembly AS approaches the tree TR, the linear material W is prevented from getting caught on the tree TR or an obstacle around the tree TR. It is preferable that the tubular arm 21m has an arc-shaped internal passage. When the internal passage of the tubular arm 21m extends in an arc, the linear material W can move smoothly along the arc-shaped internal passage.

[0032] 8, the first arm M1 is a tubular arm 21m having a wire W disposed in its internal passage. The second arm M2 does not have a wire W disposed therein. The second arm M2 may be a tubular arm 31m or a solid arm.

[0033] In the example shown in FIG. 9, the tubular arm 21m has an inlet 211m through which the wire W is introduced and an outlet 212m through which the wire W is removed. In this case, the wire W is disposed along the internal passage of the tubular arm 21m between the inlet 211m and the outlet 212m. In the example shown in FIG. 9, the inlet 211m is an opening provided in the tubular side wall of the tubular arm 21m. Also, the outlet 212m is an opening provided at the end of the tubular arm 21m. In the example shown in FIG. 9, the first part 11 is disposed adjacent to the end of the tubular arm 21m. When the assembly AS is in the first state described above, the first part 11 may be disposed in contact with the end of the tubular arm 21m. A guide member 28 may be disposed at the inlet 211m. In the example shown in FIG. 9, a passage for guiding the wire W is formed inside the guide member 28. The wire material W is introduced into the internal passage of the tubular arm 21m through the passage and the inlet 211m. The guide member 28 is preferably flexible. In this case, the flexure of the guide member 28 can prevent the wire material W from being excessively bent. The guide member 28 may be formed of a coil spring.

[0034] (First arm M1 and second arm M2) 1, the first support member 21 includes a first arm M1, and the second support member 31 includes a second arm M2. Each of the first arm M1 and the second arm M2 is swingable so that a distance L1 between a first part 11 supported by the first support member 21 (more specifically, the first arm M1) and a second part 12 supported by the second support member 31 (more specifically, the second arm M2) is reduced.

[0035] 1, both the first arm M1 and the second arm M2 are swinging arms that can swing relative to the base structure 4. When both the first arm M1 and the second arm M2 are swinging arms, the amount of swing of the first arm M1 required to ensure an opening width through which the standing tree TR can pass is small, and the amount of swing of the second arm M2 required to ensure an opening width through which the standing tree TR can pass is small. Therefore, even if there are obstacles around the standing tree TR, the assembly AS can easily approach the standing tree TR.

[0036] In the example shown in FIG. 8, the first arm M1 can swing around a first axis AX1. The second arm M2 can swing around a second axis AX2 parallel to the first axis AX1. The first arm M1 can be rotated around the first axis AX1 by a predetermined angle less than 90 degrees, or can be rotated around the first axis AX1 by a predetermined angle less than 60 degrees. The second arm M2 can be rotated around the second axis AX2 by a predetermined angle less than 90 degrees, or can be rotated around the second axis AX2 by a predetermined angle less than 60 degrees. In the example shown in FIG. 8, the second axis AX2 is spaced apart from the first axis AX1. Alternatively, the second axis AX2 can be coaxial with the first axis AX1. The distance between the first axis AX1 and the second axis AX2 is, for example, 15 cm or less, or 10 cm or less. When the distance between the first axis AX1 and the second axis AX2 is small, the size of the base structure 4 can be made compact.

[0037] Alternatively, as illustrated in FIG. 10, one of the first arm M1 and the second arm M2 may be a swinging arm that can swing relative to the base structure 4, and the other of the first arm M1 and the second arm M2 may be a fixed arm that cannot swing relative to the base structure 4.

[0038] In the example shown in FIG. 8 (or FIG. 10), when the tip e1 of the first arm M1 and the tip e2 of the second arm M2 are separated from each other at their maximum distance, the distance L2 between the tip e1 of the first arm M1 and the tip e2 of the second arm M2 is, for example, 25 cm or more, 35 cm or more, or 45 cm or more. When the distance L2 is 25 cm or more, a sufficient distance can be secured between the first part 11 supported at the tip of the first arm M1 and the second part 12 supported at the tip of the second arm M2. Therefore, it is easy to move the assembly AS so that the first passage opening OP1 provided between the first part 11 and the second part 12 crosses the standing tree TR. When the tip e1 of the first arm M1 and the tip e2 of the second arm M2 are separated by the maximum distance, the distance L2 between the tip e1 of the first arm M1 and the tip e2 of the second arm M2 is, for example, less than 100 cm, less than 80 cm, or less than 60 cm.

[0039] As illustrated in FIG. 8, the total width of the assembly AS in a state where the tip e1 of the first arm M1 and the tip e2 of the second arm M2 are separated from each other to the maximum is defined as width L3. In the example illustrated in FIG. 8, the width L3 is 1.7 times or less, 1.6 times or less, or 1.5 times or less of the distance L2 between the tip e1 of the first arm M1 and the tip e2 of the second arm M2 in a state where the tip e1 of the first arm M1 and the tip e2 of the second arm M2 are separated from each other to the maximum. Since the width L3 is not excessively large, the assembly AS is unlikely to get caught on obstacles around the standing tree TR when the assembly AS approaches the standing tree TR. Furthermore, since the ratio of the distance L2 to the width L3 is not excessively small, the size of the first passage opening OP1 provided between the first part 11 and the second part 12 is sufficiently secured.

[0040] In the example shown in FIG. 8, the first arm M1 has an arc-shaped outer shape. When the first arm M1 has an arc-shaped outer shape, the first arm M1 is less likely to get caught on the tree TR or an obstacle around the tree TR when the assembly AS approaches the tree TR. In addition, when the first arm M1 has an arc-shaped outer shape, an arc-shaped internal passage is easily formed inside the first arm M1. The arc-shaped internal passage appropriately guides the movement of the linear material W. Note that, in the example shown in FIG. 8, the linear material W is arranged to pass through the internal passage of the first arm M1, but alternatively, the linear material W may be arranged along the first arm M1 on the outside of the first arm M1.

[0041] 8, the second arm M2 has an arc-shaped outer shape. When the second arm M2 has an arc-shaped outer shape, the second arm M2 is less likely to get caught on the tree TR or an obstacle around the tree TR when the assembly AS approaches the tree TR.

[0042] There is no particular limitation on the material of each of the first arm M1 and the second arm M2, and each of the first arm M1 and the second arm M2 may be made of metal.

[0043] (Base Structure 4) In the example shown in FIG. 11, the assembly AS includes a base structure 4 that swingably supports the arm M. The base structure 4 may swingably support each of the first arm M1 and the second arm M2. The base structure 4 is composed of a plurality of components. The base structure 4 may have a first pin P1 that supports the first arm M1, and may have a second pin P2 that supports the second arm M2.

[0044] (Part 3 43) In the example shown in Fig. 11, the assembly AS includes a third part 43 that is fixed to the tree TR. When the third part 43 of the assembly AS is fixed to the tree TR, the assembly AS does not wobble when the state of the assembly AS is switched from the above-mentioned first state (more specifically, the state in which the first part 11 and the second part 12 are separated) to the above-mentioned second state (more specifically, the state in which the first part 11 and the second part 12 are integrated). In addition, the assembly AS does not wobble when the arm M of the assembly AS is swung (more specifically, when the first arm M1 is swung about the first axis AX1 and the second arm M2 is swung about the second axis AX2).

[0045] 11, the third part 43 is disposed on the base structure 4. The third part 43 preferably includes at least one protrusion 43a (e.g., a nail, a needle, or a screw member) that can be pierced into the standing tree TR. The third part 43 may have a plurality of protrusions 43a that can be pierced into the standing tree TR.

[0046] (Wire material W) The wire W attached to the first part 11 has flexibility. The wire W attached to the first part 11 is, for example, a flexible wire, a wire, or a twisted thread. The wire may be made of a resin such as polyethylene, nylon, or aramid, or may be made of a metal. In the example shown in FIG. 3, a first end Wa of the wire W is attached to the first part 11. The method of attaching the first end Wa of the wire W to the first part 11 is arbitrary. The first end Wa of the wire W may be attached to the first part 11 by tying the wire W to the first part 11. Alternatively, the first end Wa of the wire W may be attached to the first part 11 by being clamped by the first part 11. The first end Wa of the wire W may also be attached to the first part 11 by crimping, gluing, or the like.

[0047] (Winding device 9) 3, the wire arrangement tool 1 preferably includes a winding device 9 (more specifically, a reel 9a) capable of winding the wire W and supplying the wire W toward the assembly AS (more specifically, the first arm M1). A second end of the wire W may be fixed to the winding device 9.

[0048] The winding device 9 (more specifically, the reel 9a) may have a wound body 91 (e.g., a bobbin) around which the linear material W is wound, a support 92 that rotatably supports the wound body 91, and an operating member 93 that rotates the wound body 91 relative to the support 92. When the operating member 93 is rotated in a first rotation direction, the linear material W is wound onto the wound body 91. On the other hand, when the operating member 93 is rotated in a second rotation direction opposite to the first rotation direction, the linear material W is supplied from the wound body 91 to the assembly AS.

[0049] (First part 11 and second part 12) 3, the first component 11 includes a first magnetic body 111 (for example, a ferromagnetic body 111m such as iron, or a magnet). The second component 12 includes a second magnetic body 121 (for example, a magnet 121m or a ferromagnetic body such as iron). A magnetic force (more specifically, a force that attracts each other) acts between the first magnetic body 111 and the second magnetic body 121.

[0050] In the example shown in Figure 4 (see the lower diagram in Figure 4), when the assembly AS is in the third state described above (more specifically, when the first part 11 and the second part 12 are integrated), the integrated state of the first part 11 and the second part 12 is maintained by the magnetic force acting between the first part 11 and the second part 12 (i.e., by the magnetic force acting between the first magnetic body 111 and the second magnetic body 121).

[0051] 5, while the linear material W is in contact with the tree TR, the assembly AS is moved in a direction away from the tree TR. If the first part 11 and the second part 12 are maintained in an integrated state by a magnetic force or the like, the first part 11 is unlikely to fall off the second part 12 when the assembly AS is moved in a direction away from the tree TR.

[0052] The force that maintains the first part 11 and the second part 12 in an integrated state is not limited to a magnetic force. As illustrated in FIG. 12, the force that maintains the first part 11 and the second part 12 in an integrated state may be a mechanical engagement force. In the example illustrated in FIG. 12, the first part 11 includes a first engagement portion 115, and the second part 12 includes a second engagement portion 125. In the example illustrated in FIG. 12 (see the lower diagram in FIG. 12), the first part 11 and the second part 12 are maintained in an integrated state by the engagement force acting between them (i.e., by the engagement force acting between the first engagement portion 115 and the second engagement portion 125). In this case as well, when the assembly AS is moved in a direction away from the standing tree TR while the linear material W is in contact with the standing tree TR, the first part 11 is unlikely to fall off the second part 12.

[0053] (Position maintaining member 45) 11, the assembly AS includes a position maintaining member 45. The position maintaining member 45 maintains the relative position of the first part 11 with respect to the second part 12 when the assembly AS is in the above-mentioned first state (in other words, when the first part 11 and the second part 12 are separated). In the case where the assembly AS includes a base structure 4 and an arm M that can swing with respect to the base structure 4, the position maintaining member 45 maintains the relative position of the arm M with respect to the base structure 4 when the assembly AS is in the above-mentioned first state (in other words, when the first part 11 and the second part 12 are separated).

[0054] 1, when the relative position of the first part 11 with respect to the second part 12 is fixed by the position maintaining member 45 (more specifically, when the relative position of the arm M with respect to the base structure 4 is fixed), the size of the first passage opening OP1 formed between the first part 11 and the second part 12 is maintained. Therefore, it is easy to approach the assembly AS to the standing tree TR so that the first passage opening OP1 crosses the standing tree TR.

[0055] The position maintaining member 45 may include a magnet that maintains the relative position of the first part 11 with respect to the second part 12 by magnetic force, or may include an engagement member that maintains the relative position of the first part 11 with respect to the second part 12 by mechanical engagement. Alternatively, or additionally, the position maintaining member 45 may include a biasing member 45b such as a spring (see FIG. 19, if necessary).

[0056] In the example shown in FIG. 11, the position maintaining member 45 includes a third magnetic body 453 (e.g., a magnet 453m or a ferromagnetic body such as iron) arranged on the arm M, and a fourth magnetic body 454 (e.g., a ferromagnetic body 454m such as iron, or a magnet) arranged on the base structure 4. A magnetic force (more specifically, a mutually attractive force) acts between the third magnetic body 453 and the fourth magnetic body 454. In the example shown in FIG. 11, the third magnetic body 453 (e.g., a magnet 453m) is arranged on the second arm M2. Alternatively or additionally, the third magnetic body 453 (e.g., a magnet 453m) may be arranged on the first arm M1.

[0057] 11, the relative position of the arm M with respect to the base structure 4 (more specifically, each of the relative positions of the first arm M1 and the second arm M2 with respect to the base structure 4) is maintained until a force exceeding the magnetic attractive force acting between the third magnetic body 453 and the fourth magnetic body 454 acts on the arm M. On the other hand, when a force exceeding the magnetic attractive force acting between the third magnetic body 453 and the fourth magnetic body 454 acts on the arm M, the arm M (more specifically, each of the first arm M1 and the second arm M2) moves relative to the base structure 4.

[0058] Alternatively, the position maintaining member 45 may include a first engagement portion disposed on the arm M and a second engagement portion disposed on the base structure 4. In this case, the relative position of the arm M with respect to the base structure 4 (more specifically, each of the relative positions of the first arm M1 and the second arm M2 with respect to the base structure 4) is maintained until a force acting on the arm M exceeds an engagement force acting between the first engagement portion and the second engagement portion. On the other hand, when a force acting on the arm M exceeds an engagement force acting between the first engagement portion and the second engagement portion, the arm M (more specifically, each of the first arm M1 and the second arm M2) moves relatively to the base structure 4.

[0059] (Bar member 5) In the example shown in FIG. 13, the wire placement tool 1 includes a rod member 5 to which the assembly AS is attached. The rod member 5 has a tip portion 51 to which the assembly AS is attached. The rod member 5 also has a base end portion 53. The base end portion 53 is a portion that is held by, for example, an operator. A winding device 9 (more specifically, a reel 9a capable of winding up the wire W) may be attached to the rod member 5 (more specifically, the base end portion 53 of the rod member 5).

[0060] When the linear material placement tool 1 includes the rod member 5, the linear material placement tool 1 can be used to move the assembly AS toward a relatively tall area of ​​the standing tree TR.

[0061] The rod member 5 is preferably extendable. In this case, it is easy to transport the rod member 5 in a contracted state. In addition, the rod member 5 in an extended state can be used to move the assembly AS to a relatively tall area of ​​the tree TR.

[0062] In the example shown in Fig. 14, when the extendable rod member 5 is in the most extended state, the length L4 of the rod member 5 is, for example, 4m or more, 5m or more, 6m or more, or 7m or more. When the length L4 of the rod member 5 is 4m or more, the assembly AS can be made to approach a higher area of ​​the standing tree TR using the extended rod member 5. When the extendable rod member 5 is in the most contracted state, the length L5 of the rod member 5 is, for example, less than 4m, less than 3m, or less than 2m.

[0063] (Operation unit 57) In the example shown in FIG. 13, the wire material placement tool 1 (more specifically, the rod member 5) has an operation unit 57. The operation unit 57 is capable of at least one of switching the state of the assembly AS from the above-mentioned first state (see FIG. 13) to the above-mentioned second state (see FIG. 15) and switching the state of the assembly AS from the above-mentioned second state (see FIG. 15) to the above-mentioned third state (see FIG. 16). In the example shown in FIG. 13, the operation unit 57 is disposed at a position away from the assembly AS. Thus, the operation unit 57 can remotely control the switching of the state of the assembly AS.

[0064] As illustrated in FIG. 13, the operating unit 57 may be configured by the base end portion 53 of the rod member 5. The operating unit 57 (more specifically, the base end portion 53 of the rod member 5) may be configured to rotate about the central axis of the rod member 5 in the first operation direction MR1, thereby switching the state of the assembly AS from the above-mentioned first state to the above-mentioned second state. More specifically, in a state in which the third part 43 is fixed to the tree TR (more specifically, in a state in which the protruding part 43a is stuck into the tree TR), the operating unit 57 may be configured to rotate about the central axis of the rod member 5 in the first operation direction MR1, thereby switching the state of the assembly AS from the above-mentioned first state to the above-mentioned second state. In this case, the third part 43 (more specifically, the protruding part 43a) prevents the entire assembly AS from being rotated in the first operation direction MR1 together with the rod member 5 when the rod member 5 is operated in the first operation direction MR1. In other words, the third part 43 receives a reaction force from the tree TR when the rod member 5 is operated in the first operation direction MR1. As a result, the switching from the first state to the second state described above is performed smoothly.

[0065] In the example shown in FIG. 15, after the first part 11 and the second part 12 are integrated, the operating part 57 (more specifically, the base end part 53 of the rod member 5) may be rotated about the central axis of the rod member 5 in the second operation direction MR2 (more specifically, the direction opposite to the first operation direction MR1), thereby switching the state of the assembly AS from the second state to the third state. More specifically, in a state in which the third part 43 is fixed to the tree TR (more specifically, in a state in which the protruding part 43a is stuck into the tree TR), the operating part 57 may be rotated about the central axis of the rod member 5 in the second operation direction MR2, thereby switching the state of the assembly AS from the second state to the third state. In this case, the third part 43 (more specifically, the protruding part 43a) prevents the entire assembly AS from being rotated in the second operation direction MR2 together with the rod member 5 when the rod member 5 is operated in the second operation direction MR2. In other words, the third part 43 receives a reaction force from the tree TR when the rod member 5 is operated in the second operation direction MR2. As a result, the second state described above can be smoothly switched to the third state described above.

[0066] (Force transmission mechanism F) As illustrated in FIG. 17, the linear material placement tool 1 may have a force transmission mechanism F that converts the operating force acting on the operating portion 57 of the rod member 5 into a force that switches the state of the assembly AS from the above-described first state to the above-described second state, or a force that switches the state of the assembly AS from the above-described second state to the above-described third state.

[0067] 17, the force transmission mechanism F has a mounting part 47 attached to the rod member 5, and at least one gear G that converts rotation of the mounting part 47 (more specifically, rotation of the mounting part 47 around the central axis of the rod member 5) into swinging motion of the first arm M1 around the first axis AX1. Alternatively or additionally, the force transmission mechanism F may have at least one gear G that converts rotation of the mounting part 47 (more specifically, rotation of the mounting part 47 around the central axis of the rod member 5) into swinging motion of the second arm M2 around the second axis AX2.

[0068] In the example shown in FIG. 17, when the rod member 5 (more specifically, the operating portion 57 of the rod member 5) is rotated in the first operating direction MR1, the mounting portion 47 and the first gear G1 arranged on the mounting portion 47 rotate in the first direction R1. The first gear G1 is engaged with the second gear G2 arranged on the first pin P1. The first arm M1 is fixed to the second gear G2 directly or via an arbitrary member. Therefore, when the first gear G1 rotates in the first direction R1, the second gear G2 and the first arm M1 rotate in the second direction R2 around the first axis AX1. In this way, the first arm M1 swings around the first axis AX1.

[0069] In the example shown in FIG. 17, the third gear G3 arranged on the first pin P1 meshes with the fourth gear G4 arranged on the second pin P2. The second arm M2 is fixed to the fourth gear G4 directly or via an arbitrary member. Therefore, when the second gear G2 rotates in the second direction R2, the third gear G3 rotates in the second direction R2, and the fourth gear G4 and the second arm M2 rotate in the third direction R3 around the second axis AX2. In this way, the second arm M2 swings around the second axis AX2.

[0070] In the example shown in FIG. 17, when the rod member 5 (more specifically, the operating portion 57 of the rod member 5) is rotated in the first operation direction MR1, the first arm M1 swings about the first axis AX1 and the second arm M2 swings about the second axis AX2 so that the distance between the tip of the first arm M1 and the tip of the second arm M2 decreases. In this way, the state of the assembly AS can be switched from the above-mentioned first state to the above-mentioned second state. Note that the configuration may be such that only one of the first arm M1 and the second arm M2 swings when the rod member 5 (more specifically, the operating portion 57 of the rod member 5) is rotated in the first operation direction MR1.

[0071] In the example shown in FIG. 17, when the rod member 5 (more specifically, the operating portion 57 of the rod member 5) is rotated in the second operation direction MR2, the first arm M1 swings about the first axis AX1 and the second arm M2 swings about the second axis AX2 so that the distance between the tip of the first arm M1 and the tip of the second arm M2 increases. In this way, the state of the assembly AS can be switched from the above-mentioned second state to the above-mentioned third state. Note that the configuration may be such that only one of the first arm M1 and the second arm M2 swings when the rod member 5 (more specifically, the operating portion 57 of the rod member 5) is rotated in the second operation direction MR2.

[0072] The force transmission mechanism F is not limited to the mechanism F1 using multiple gears. As illustrated in Fig. 18, the force transmission mechanism F may be a mechanism F2 using multiple link members LK, or as illustrated in Fig. 19, the force transmission mechanism F may be a mechanism F3 using a cam 48.

[0073] Fig. 19 shows an example of a force transmission mechanism F using a cam 48. In the example shown in Fig. 19, the spherical body 48b attached to the rod member 5 moves in a direction DR1 in which the spherical body 48b presses a pressed member 49a attached to the first arm M1, causing the first arm M1 to swing about the first axis AX1. Also, the spherical body 48b attached to the rod member 5 moves in a direction DR1 in which the spherical body 48b presses a pressed member 49b attached to the second arm M2, causing the second arm M2 to swing about the second axis AX2. In this way, the state of the assembly AS is switched from the first state described above to the second state described above.

[0074] 19, when the spherical body 48b moves in the direction DR2 away from the pressed member 49a, the biasing force of the biasing member 45b causes each of the first arm M1 and the second arm M2 to swing so that the distance between the tip end of the first arm M1 and the tip end of the second arm M2 increases, and the state of the assembly AS is thus switched from the second state described above to the third state described above.

[0075] 19, the cam 48 constituting a part of the force transmission mechanism F is a spherical body 48b, but it goes without saying that the shape of the cam is not limited to a spherical shape. Also, the cam 48 (e.g., the spherical body 48b) may be configured to move in the direction DR1 in which the pressed members (49a, 49b) are pressed by rotating the operation part 57 of the rod member 5, or the cam 48 (e.g., the spherical body 48b) may be configured to move in the direction DR1 in which the pressed members (49a, 49b) are pressed by linearly moving the operation part 57 of the rod member 5 (e.g., moving upward).

[0076] (Force transmission mechanism E) 17 to 19, the force transmission mechanism F converts the operating force acting on the operating portion 57 of the rod member 5 into a force that switches the state of the assembly AS from the above-mentioned first state to the above-mentioned second state. Alternatively, or additionally, as illustrated in Fig. 20, the linear material placement tool 1 (more specifically, the assembly AS) may have a force transmission mechanism E that converts a force that the pressed part 42 of the assembly AS receives from the standing tree TR into a force that switches the state of the assembly AS from the above-mentioned first state to the above-mentioned second state.

[0077] In the example shown in FIG. 20, the assembly AS has a pressed part 42 that receives a force from a standing tree TR. The pressed part 42 may be the above-mentioned third part 43 (more specifically, the protruding part 43a) or another part. In the example shown in FIG. 20, the pressed part 42 (more specifically, the protruding part 43a) is pressed against the standing tree TR, and the pressed part 42 receives a force (more specifically, a reaction force) from the standing tree TR. The force transmission mechanism E converts the force that the pressed part 42 of the assembly AS receives from the standing tree TR into a force that switches the state of the assembly AS from the above-mentioned first state to the above-mentioned second state.

[0078] 20, the force transmission mechanism E includes a cam 48. The cam 48 presses the base end of the first arm M1, and the first arm M1 pressed by the cam 48 swings around the first axis AX1. The cam 48 may simultaneously press the base end of the first arm M1 and the base end of the second arm M2. In this case, the first arm M1 pressed by the cam 48 swings around the first axis AX1, and the second arm M2 pressed by the cam 48 swings around the second axis AX2.

[0079] In the example shown in FIG. 20, the state of the assembly AS can be switched from the above-mentioned first state to the above-mentioned second state simply by pressing the pressed part 42 against the standing tree TR.

[0080] In the example shown in Fig. 20, it is not necessary to provide the operating unit 57 for switching the state of the assembly AS from the first state to the second state on the rod member 5. In the example shown in Fig. 20, the operating unit 57 for switching the state of the assembly AS from the first state to the second state may be provided on the rod member 5. In other words, the linear material placement tool 1 may have (1) a first force transmission mechanism F that converts an operating force acting on the operating unit 57 of the rod member 5 into a force for switching the state of the assembly AS from the first state to the second state, and (2) a second force transmission mechanism E that converts a force that the pressed part 42 of the assembly AS receives from the standing tree TR into a force for switching the state of the assembly AS from the first state to the second state.

[0081] The force transmission mechanism F that utilizes the force received from the standing tree TR may include multiple gears, multiple link members, or a cam, similar to the force transmission mechanism E that utilizes the force by which the operating unit 57 is operated.

[0082] In the example shown in FIG. 17 to FIG. 20, the state of the assembly AS is switched from the first state to the second state (or the state of the assembly AS is switched from the second state to the third state) using human power as a source. Alternatively or additionally, the state of the assembly AS may be switched from the first state to the second state or from the second state to the third state using the driving force of a motor as a source. In other words, the wire material placement tool 1 may have a motor that switches the state of the assembly AS from the first state to the second state (or a motor that switches the state of the assembly AS from the second state to the third state). The wire material placement tool 1 may also have an operating unit for operating the motor. The operating unit is disposed at a position away from the assembly AS. The operating unit may be a switch disposed on the rod member 5 or a switch disposed on a remote control.

[0083] When the wire placement tool 1 has a motor that switches the state of the assembly AS, the motor may be disposed in the assembly AS or in the rod member 5. When the motor is disposed in the rod member 5, a force transmission mechanism is provided in the rod member 5 to transmit the driving force of the motor to the assembly AS.

[0084] (Members constituting the base structure 4) In the example shown in Fig. 11, the base structure 4 supports the first arm M1 so as to be swingable around a first axis AX1. The base structure 4 includes a first pin P1 that supports the first arm M1, and at least one base plate 41 that swingably supports the first arm M1 via the first pin P1. In the example shown in Fig. 11, the base structure 4 includes the first pin P1, a first base plate 41a, and a second base plate 41b, and the first arm M1 is supported by the first base plate 41a and the second base plate 41b so as to be swingable around the first pin P1 via the first pin P1.

[0085] In the example shown in Fig. 11, the base structure 4 supports the second arm M2 to be swingable around the second axis AX2. The base structure 4 includes a second pin P2 that supports the second arm M2, and at least one base plate 41 that swingably supports the second arm M2 via the second pin P2. In the example shown in Fig. 11, the base structure 4 includes the second pin P2, a first base plate 41a, and a second base plate 41b, and the second arm M2 is supported by the first base plate 41a and the second base plate 41b via the second pin P2 to be swingable around the second pin P2.

[0086] 11, the first axis AX1 and the second axis AX2 are not coaxial, and the first pin P1 supporting the first arm M1 and the second pin P2 supporting the second arm M2 are separate members. Alternatively, when the first axis AX1 and the second axis AX2 are coaxial, the first arm M1 and the second arm M2 may be supported by a single pin.

[0087] In the example shown in FIG. 11, the base structure 4 includes an attachment portion 47 attached to the rod member 5. The attachment portion 47 may be supported by the first base plate 41a so as to be rotatable relative to the first base plate 41a. The rod member 5 and the attachment portion 47 may be integrally rotatable relative to the first base plate 41a. In the example shown in FIG. 13, the rod member 5 and the attachment portion 47 are rotatable relative to the first base plate 41a around the central axis of the rod member 5.

[0088] The base structure 4 may be provided with a member constituting at least a part of the above-mentioned force transmission mechanism F (or the above-mentioned force transmission mechanism E). In the example shown in FIG. 11, the base structure 4 is provided with a gear G constituting at least a part of the above-mentioned force transmission mechanism F. As shown in FIG. 17, the base structure 4 may be provided with a first gear G1, a second gear G2, a third gear G3, and a fourth gear G4. Alternatively, or additionally, the base structure 4 may be provided with a link member constituting at least a part of the force transmission mechanism F that utilizes the force by which the operating unit 57 is operated, or a cam constituting at least a part of the force transmission mechanism F. The base structure 4 may be provided with a gear constituting at least a part of the force transmission mechanism E that utilizes the force received from the standing tree TR, a link member constituting at least a part of the force transmission mechanism E, or a cam constituting at least a part of the force transmission mechanism E.

[0089] A gear, a link member, or a cam 48 constituting at least a part of the force transmission mechanism F (or the force transmission mechanism E) may be disposed between the first base plate 41a and the second base plate 41b.

[0090] As illustrated in Fig. 11, a third component 43 (more specifically, a protruding portion 43a) may be disposed on the base structure 4. In the example illustrated in Fig. 11, the third component 43 is attached to the base structure 4 via a first mounting plate 44a.

[0091] 11, at least a part of the position maintaining member 45 (for example, the fourth magnetic body 454) may be disposed on the base structure 4. In the example shown in FIG. 11, the fourth magnetic body 454 is attached to the base structure 4 via the second mounting plate 44b.

[0092] (Wire material arrangement method) Next, a wire material arrangement method according to the first embodiment will be described with reference to Fig. 1 to Fig. 27. Fig. 21 to Fig. 26 are schematic perspective views showing the state in which each step of the wire material arrangement method according to the first embodiment is being performed. Fig. 27 is a flow chart showing an example of the wire material arrangement method according to the first embodiment.

[0093] In the linear material placement method in the first embodiment, a linear material placement tool is used to place a linear material W around a standing tree TR. The linear material placement tool used in the linear material placement method in the first embodiment may be the linear material placement tool 1 in the first embodiment, or may be another linear material placement tool.

[0094] In a first step ST1, a wire placement tool is prepared. The first step ST1 is a preparation step. As illustrated in FIG. 13, the wire placement tool 1 prepared in the preparation step (first step ST1) includes an assembly AS. The assembly AS also includes a first part 11 to which a first portion W1 of the wire W (see FIG. 1, if necessary) is attached, a first support member 21 capable of supporting the first part 11, and a second part 12. Additionally, the wire placement tool 1 may include a rod member 5 that supports the assembly AS.

[0095] Since the assembly AS and the rod member 5 have already been explained, repeated explanations of the assembly AS and the rod member 5 will be omitted.

[0096] When the rod member 5 is extendable, the preparation step (first step ST1) may include extending the rod member 5 so that the length of the rod member 5 increases.

[0097] In a second step ST2, the assembly AS is arranged around the standing tree TR. The second step ST2 is an assembly arrangement step.

[0098] 21 and 22, in the assembly placement step (second step ST2), the assembly AS is placed around the standing tree TR by moving the assembly AS so that the first passage opening OP1 formed between the first part 11 and the second part 12 crosses the tree TR. Note that, as exemplified in Fig. 1 (see the lower diagram in Fig. 1), after the assembly placement step (second step ST2) is performed, the assembly AS placed around the standing tree TR does not need to completely surround the standing tree TR.

[0099] The assembly placement process (second step ST2) includes moving the assembly AS in the first state described above (in other words, the assembly AS in a state in which a first passage opening OP1 through which the standing tree TR can pass is formed between the first part 11 and the second part 12) relative to the standing tree TR.

[0100] The assembly arrangement step (second step ST2) is preferably performed in a state in which the relative position of the first component 11 with respect to the second component 12 is maintained by a position maintaining member 45.

[0101] 21 and 22, the assembly placement step (second step ST2) is performed by moving the rod member 5 supporting the assembly AS. For example, the assembly placement step (second step ST2) is performed by tilting the rod member 5 supporting the assembly AS.

[0102] As illustrated in FIG. 22, the assembly arrangement step (second step ST2) may include fixing a third part 43 (more specifically, the protruding portion 43a) of the assembly AS to the standing tree TR.

[0103] As illustrated in Figures 2 and 3, in the third step ST3, the first part 11 is transferred from the first support member 21 of the assembly AS to the second part 12 of the assembly AS. The third step ST3 is a transfer process. In the example shown in Figure 2, the transfer process (third step ST3) includes switching the state of the assembly AS from the above-mentioned first state (in other words, a state in which a first passage opening OP1 through which the tree TR can pass is formed between the first part 11 and the second part 12) to the above-mentioned second state (in other words, a state in which the gap between the first support member 21 and the second part 12 is reduced).

[0104] As illustrated in FIG. 2, the transfer step (third step ST3) includes decreasing the distance between the first part 11 and the second part 12.

[0105] The transfer step (third step ST3) may include swinging the arm M supporting one of the first part 11 and the second part 12 so as to reduce the distance between the first part 11 and the second part 12. In the example described in Fig. 2, the transfer step (third step ST3) includes swinging both the first arm M1 supporting the first part 11 and the second arm M2 supporting the second part 12 so as to reduce the distance between the first part 11 and the second part 12.

[0106] The swinging of arm M (more specifically, the swinging of both first arm M1 and second arm M2) may be performed by operating the operating unit 57, as illustrated in FIG. 13, or may be performed by pressing the pressed part 42 against a standing tree TR, as illustrated in FIG. 20.

[0107] 22, when an operating unit 57 (more specifically, a base end portion 53 of the rod member 5) disposed on the rod member 5 is operated in a first operating direction MR1, both the first arm M1 and the second arm M2 swing so as to reduce the distance between the first part 11 and the second part 12. Note that swinging the first arm M1 and the second arm M2 using an operating force acting on the operating unit 57 may be performed using a force transmission mechanism F as exemplified in FIGS.

[0108] Alternatively, as illustrated in Fig. 20, the pressed part 42 disposed in the assembly AS may be pressed against the tree TR, thereby causing both the first arm M1 and the second arm M2 to swing so as to reduce the distance between the first part 11 and the second part 12. Note that swinging the first arm M1 and the second arm M2 using the force received by the pressed part 42 from the tree TR may be performed using a force transmission mechanism E as illustrated in Fig. 20.

[0109] 3, the transfer step (third step ST3) includes integrating the first part 11 and the second part 12 by magnetic force. Alternatively, as illustrated in FIG 12, the transfer step (third step ST3) may include integrating the first part 11 and the second part 12 by engagement.

[0110] FIG. 23 shows the state after the delivery step (third step ST3) has been executed.

[0111] In a fourth step ST4, the wire W is suspended between the composite body 10 of the first part 11 and the second part 12 and the first support member 21. The fourth step ST4 is a wire suspension step.

[0112] In the example shown in FIG. 3, the wire material passing step (fourth step ST4) is automatically performed by executing the transfer step (third step ST3). More specifically, in the example shown in FIG. 3, the first part 11 and the second part 12 approach each other, and the magnetic force acting between them increases. As a result, the first part 11 moves from the first support member 21 to the second part 12 by the magnetic force (transfer step). This movement forms a composite body 10 of the first part 11 and the second part 12, and the wire material W is passed between the first part 11 and the first support member 21 (wire material passing step).

[0113] Alternatively, the wire-shaped material transfer step (fourth step ST4) may be performed after the transfer step (third step ST3) is performed. For example, assume that the transfer step (third step ST3) causes the first part 11 to be in contact with both the second part 12 and the first support member 21. In this case, one of the first support member 21 and the first part 11 is moved away from the other of the first support member 21 and the first part 11, so that the wire-shaped material W is transferred between the first part 11 and the first support member 21.

[0114] As illustrated in Fig. 4 (see the upper diagram in Fig. 4), it is preferable that the linear material hanging step (fourth step ST4) be performed so that the standing tree TR is completely surrounded by the assembly AS and the linear material W hung between the complex 10 and the first support member 21. In other words, it is preferable that the linear material hanging step (fourth step ST4) be performed so that the assembly AS and the linear material W form an enclosure surrounding the standing tree TR. In the example shown in Fig. 4, the linear material hanging step (fourth step ST4) is performed so that the assembly AS and the linear material W form an annular body, the assembly AS constitutes a part of the annular body, and the linear material W hung between the complex 10 and the first support member 21 constitutes the other part of the annular body.

[0115] The wire-shaped material transfer step (fourth step ST4) may include drawing out the wire-shaped material W from an opening of the first supporting member 21 (for example, an outlet 212m provided at an end of the first supporting member 21 shown in FIG. 9). The wire-shaped material transfer step (fourth step ST4) may also include supplying the wire-shaped material W from the winding device 9 (more specifically, the reel 9a) toward the assembly AS.

[0116] In the fifth step ST5, a second passage opening OP2 through which the standing tree TR can pass is formed between the complex 10 and the first support member 21. The fifth step ST5 is a second passage opening forming step.

[0117] In the example shown in Figure 4, the process of forming the second passage opening OP2 (fifth step ST5) includes switching the state of the assembly AS from the above-mentioned second state (in other words, a state in which the gap between the first support member 21 and the second part 12 is reduced) to the above-mentioned third state (in other words, a state in which a second passage opening OP2 through which the standing tree TR can pass is formed between the complex 10 and the first support member 21).

[0118] In the example described in FIG. 4, the step of forming the second passage opening OP2 (fifth step ST5) includes expanding the gap between the first part 11 and the first support member 21. The step of forming the second passage opening OP2 (fifth step ST5) may include swinging the arm M so that the gap between the first part 11 and the first support member 21 is expanded. In the example described in FIG. 4, the step of forming the second passage opening OP2 (fifth step ST5) includes swinging both the first arm M1 and the second arm M2 supporting the composite body 10 so that the gap between the first part 11 and the first support member 21 is expanded.

[0119] The swing of the arm M (more specifically, the swing of both the first arm M1 and the second arm M2) is performed by operating the operating unit 57, for example.

[0120] 23, when the operating unit 57 disposed on the rod member 5 is operated in the second operating direction MR2, both the first arm M1 and the second arm M2 swing so as to increase the distance between the first component 11 and the first support member 21. Note that swinging the first arm M1 and the second arm M2 using an operating force acting on the operating unit 57 may be performed using a force transmission mechanism F as exemplified in FIGS.

[0121] Alternatively, or additionally, the swinging of arm M (more specifically, the swinging of both first arm M1 and second arm M2) may be performed by pressing arm M against the tree TR as the assembly AS is pulled back in a direction away from the tree TR.

[0122] Further alternatively, the swinging of the arm M (more specifically, the swinging of both the first arm M1 and the second arm M2) may be performed using the biasing force of the biasing member 45b (see FIG. 19, if necessary).

[0123] The step of forming the second passage opening OP2 (fifth step ST5) may include pulling out the wire material W from an opening of the first support member 21 (for example, the outlet 212m provided at the end of the first support member 21 shown in FIG. 9). The step of forming the second passage opening OP2 (fifth step ST5) may also include supplying the wire material W from the winding device 9 (more specifically, the reel 9a) toward the assembly AS.

[0124] FIG. 24 shows a state after the step of forming the second passage opening OP2 (fifth step ST5) has been performed.

[0125] In a sixth step ST6, the linear material W is arranged around the standing tree TR. The sixth step ST6 is a linear material arrangement step.

[0126] More specifically, as illustrated in Figure 5, in the linear material placement process (sixth step ST6), the assembly AS is moved so that the second passage opening OP2 formed between the composite body 10 and the first support member 21 crosses the standing tree TR, thereby placing the linear material W around the standing tree TR.

[0127] The linear material placement process (sixth step ST6) includes moving the assembly AS in the third state described above (in other words, the assembly AS in a state in which a second passage opening OP2 through which the standing tree TR can pass is formed between the complex 10 and the first support member 21) relative to the standing tree TR.

[0128] The linear material arrangement step (sixth step ST6) is preferably performed in a state in which the relative position of the first support member 21 with respect to the complex 10 is maintained by the position maintaining member 45.

[0129] 24 and 25, the wire-shaped material arranging step (sixth step ST6) is performed by moving the rod member 5 supporting the assembly AS. For example, the wire-shaped material arranging step (sixth step ST6) is performed by tilting the rod member 5 supporting the assembly AS.

[0130] In a seventh step ST7, the first part 11 and the first portion W1 of the wire W attached to the first part 11 (more specifically, the first end portion Wa of the wire W) are pulled toward a worker. The seventh step ST7 is a pulling process.

[0131] The pulling step (seventh step ST7) is performed by pulling the assembly AS to the hand of the worker. If the rod member 5 is extendable, the pulling step (seventh step ST7) may include contracting the rod member 5 so that the length of the rod member 5 is shortened (see FIG. 26).

[0132] The drawing step (seventh step ST7) may include drawing out the wire material W from an opening of the first support member 21 (e.g., the outlet 212m provided at the end of the first support member 21 shown in FIG. 9). The drawing step (seventh step ST7) may also include supplying the wire material W from the winding device 9 (more specifically, the reel 9a) toward the assembly AS.

[0133] In the linear material arrangement method in the first embodiment, the assembly AS can be arranged around the standing tree TR by moving the assembly AS so that the first passage opening OP1 formed between the first part 11 and the second part 12 crosses the tree. Therefore, the assembly AS can be quickly arranged around the standing tree TR.

[0134] In the linear material arrangement method in the first embodiment, the first part 11 is handed over to the second part 12. This prevents the first part 11 and the first portion W1 of the linear material W attached to the first part 11 from falling to an undesirable position (for example, a position where they are caught on a branch of a standing tree TR).

[0135] In the linear material arrangement method in the first embodiment, the linear material W is hung between the complex 10 of the first part 11 and the second part 12 and the first support member 21. The assembly AS is moved so that the second passage opening OP2 formed between the complex 10 and the first support member 21 crosses the standing tree TR, thereby arranging the linear material W around the standing tree TR. Thus, the linear material W can be quickly arranged around the standing tree TR.

[0136] The linear material W arranged around the standing tree TR may be used to control the direction in which the standing tree TR falls during felling. The linear material W arranged around the standing tree TR may also be used to arrange another linear material (e.g., rope) stronger than the linear material W around the standing tree TR. For example, the other linear material (e.g., rope) stronger than the linear material W is connected to the first end Wa or the first part 11 of the linear material W. Thereafter, the operating member 93 of the winding device 9 is operated to pull the first end Wa (or the first part 11) of the linear material W back toward the assembly AS via the standing tree TR. In this way, the linear material W pulls the other linear material (e.g., rope) stronger than the linear material W. As a result, the other linear material (e.g., rope) stronger than the linear material W is arranged around the standing tree TR instead of the linear material W. Other strong linear materials (eg ropes) placed around the tree TR may be used to control the direction in which the tree TR falls during felling.

[0137] As described above, the linear material placement tool 1 in the first embodiment may be used to place a linear material W that controls the falling direction of a standing tree TR (or a linear material W for pulling another linear material that controls the falling direction of a standing tree TR) around a standing tree.

In addition, any component in the first embodiment or each modification can be omitted. [Industrial Applicability]
