The operation rod 10 in the present embodiment is formed by adding a plurality of split rods 13 with stoppers 14. As shown in FIG. 2, a male screw portion 11A is formed at the tip portion 11 of the operation rod 10, and the rope holding portion 20 and the rope locking portion 30, which will be described later, are detachable. The split rod 13 is formed in a tubular body whose outer diameter gradually decreases from the side of the base portion 12 toward the side of the tip portion 11. By fastening and loosening the stopper 14 arranged on the side of the base portion 12 of the split rod 13, each split rod 13 can be independently pulled out and accommodated in the longitudinal direction. Since such a configuration can adopt a mechanism similar to the expansion / contraction mechanism in a camera tripod or the like, detailed description thereof will be omitted. Further, a grip portion 15 is attached to the base portion 12 of the operation rod 10.

The rope holding portion 20 has a female screw cap body 21 screwed into the male screw portion 11A of the operating rod 10 and a spiral body 22 attached to the female screw cap body 21. The spiral body 22 is attached to the female screw cap body 21 by a known method such as welding. The spiral body 22 in the present embodiment is formed by forming a stainless steel linear member 22A into a coil spring shape. The inner diameter dimension in the internal space of the spiral body 22 is formed to be larger than the outer diameter dimension of the rope RP, and the outer diameter dimension of the spiral body 22 is formed to be about the same as the outer diameter dimension of the tip portion 11 of the operation rod 10. Further, the tip end side of the spiral body 22 may be formed in a tapered shape.

Further, in the present embodiment, the spiral spacing SP by the linear member 22A is formed to be wider than the outer diameter dimension of the rope RP and wider than the inner diameter dimension of the internal space of the spiral body 22. By adopting such a spiral body 22, the rope RP can be easily held by the rope holding portion 20, and it is easy to slip through the branch BR of the tree WD that has entered in a complicated manner, which is aimed at by the tree WD. The rope RP can be reliably sent to the position (targeted branch BR).

As is clear from FIG. 1 and the like, the extension direction central shaft 23 of the spiral body 22 is attached to the female screw cap body 21 in a state of being inclined with respect to the central axis CA in the extension direction of the female screw cap body 21 and the operation rod 10. There is. By attaching the spiral body 22 (rope holding portion 20) in a state of being inclined with respect to the central axis CA of the operating rod 10 in this way, a branch aiming at the tip TP of the rope RP held by the rope attaching jig 100 It becomes easy to wrap around along the outer surface of the BR.

The spiral body 22 in the present embodiment is formed in a substantially arc shape in front view, but is not limited to this embodiment. For example, it is also possible to adopt a form in which the entire spiral body 22 is attached to the female screw cap body 21 in a state where the entire spiral body 22 is linearly inclined to the female screw cap body 21. Further, by forming the spiral body 22 in a bent shape in the middle of the extending direction, the required length range including the attachment portion with the female screw cap body 21 becomes linear with the female screw cap body 21. It may be adopted. Regardless of which modification is adopted, the same effect as that of the spiral body 22 of the present embodiment can be obtained.

Next, the configuration of the rope attachment auxiliary jig 200 in the present embodiment will be described with reference to FIG. The rope attachment auxiliary jig 200 is used together with the rope attachment jig 100, and is used for locking the tip of the rope RP hung on the branch BR of the tree WD and pulling the rope RP to the ground. It is a thing. The rope attachment auxiliary jig 200 includes an operation rod 10 and a rope locking portion 30. Since the operation rod 10 of the rope attachment auxiliary jig 200 in the present embodiment has the same configuration as the operation rod 10 of the rope attachment jig 100, it is detailed by making the reference numerals common in the present specification. The explanation is omitted.

The rope locking portion 30 has a female screw cap body 31 screwed into the male screw portion 11A of the tip end portion 11 of the operation rod 10 and a locking tool 32 attached to the female screw cap body 31. The locking tool 32 in the present embodiment is formed in a front view J-shape (hook shape) by a stainless steel striatum, and is a female screw cap body 31 by a known method typified by wrapping with an adhesive tape or the like. It is attached to. Like the locking tool 32 in the present embodiment, a cap body 33 made of synthetic resin as a rope retaining body may be attached to the tip of the locking tool 32. By attaching such a cap body 33, it is possible to prevent the rope RP locked to the locking tool 32 from deviating from the locking tool 32, and it is easy to pull the rope RP to the ground. It is convenient in that it can be done.

Next, a method of attaching the rope RP to the tree WD using the rope attachment jig 100 and the rope attachment auxiliary jig 200 described above will be described. As shown in FIGS. 3 to 5, the operator causes the rope holding portion 20 of the rope mounting jig 100 to hold the required range of the tip portion of the rope RP. Specifically, as shown in FIGS. 3 and 4, the rope RP is inserted into the internal space from the gap portion formed by the spiral spacing SP of the spiral body 22 of the rope holding portion 20 so as to be entangled with the rope RP, and the tip portion of the rope RP. The required range is held in a state of protruding from the tip of the spiral body 22.

After the attachment of the rope RP to the rope holding portion 20 is completed, the operator operates the stopper 14 to appropriately extend the operating rod 10 and directs the rope holding portion 20 toward the target branch BR of the tree WD to be cut. Send in. In the rope RP, the required length range protruding from the spiral body 22 is reinforced by tape winding or the like. As a result, even if the spiral body 22 is curved, the tip TP of the rope RP slips between the branches BR of the tree WD, and the spiral body 22 is brought into contact with the branch BR to temporarily deform the rope RP. It can be sent to the position of the branch BR. Further, when the rope RP is sent to the position of the target branch BR of the tree WD, it is preferable to appropriately send the rope RP from the ground in accordance with the extension operation of the operation rod 10 so that the rope RP is not tensioned.

Then, as shown in FIG. 6, when the rope RP reaches the position of the target branch BR of the tree WD to be cut and does not hit the branch BR or the like, the spiral body 22 returns to the curved shape which is the initial shape, and the tree A rope RP can be hung from one side surface side of the WD branch BR to the other side surface via the back surface side. After that, as shown in FIG. 7, the operator uses the rope attachment auxiliary jig 200 to lock the tip TP of the rope RP hung on the target branch BR of the tree WD to the rope locking portion 30. After locking the tip TP of the rope RP to the locking tool 32, the operator pulls the tip TP of the rope RP to the ground position by shortening the rope attachment auxiliary jig 200 as shown in FIG. ..

Next, as shown in FIGS. 9 and 10, the operator removes the rope RP from the rope mounting jig 100 and the rope mounting auxiliary jig 200, and attaches the U clevis 40 to the faucet of the tip TP of the rope RP. An annular portion CP is formed on the rope RP. Next, the operator pulls the base side of the rope RP and tightens the branch BR of the tree WD with the annular portion CP as shown in FIG. 11, and the attachment of the rope RP is completed.

As described above, the operator uses the rope attachment jig 100 and the rope attachment auxiliary jig 200 in the present embodiment to create a narrow space in which trees WD and branch BR having a complicated shape are congested. However, the rope RP can be attached to the tree WD at the target position (branch BR). And since the worker does not have to climb the tree WD to attach the rope RP, safe work becomes possible.

Although the rope attachment jig 100 and the rope attachment auxiliary jig 200 according to the present invention have been described in detail based on the embodiments, the technical scope of the present invention is limited to the above embodiments. It's not a thing. That is, the configuration in which the gist of the present invention is appropriately modified without changing the gist of the present invention belongs to the technical scope of the present invention. For example, in the present embodiment, the operating rod 10 is formed by a plurality of split rods 13 so that the length can be adjusted, but the operating rod 10 is formed by a single member and does not have a length adjusting function. You may.

Further, in the present embodiment, a mode in which the rope RP is attached to a predetermined position (branch BR or trunk (not shown)) of the tree WD to be felled is described, but the present embodiment is not limited to this mode. .. Rope RP can also be attached to a plurality of branch BRs and trunks that are close to each other.

Further, the form in which the rope attachment jig 100 in the present embodiment is attached in a state in which the extension direction central axis 23 of the spiral body 22 is tilted with respect to the central axis CA of the operation rod 10 and the female screw cap body 21 will be described. However, it is not limited to this form. The extension direction central axis 23 of the spiral body 22 may be arranged on the same straight line as or parallel to the central axis CA of the operation rod 10 and the female screw cap body 21. As a result, the operating rod 10 and the spiral body 22 are aligned, but since the rope RP protrudes from the tip of the spiral body 22, the spiral body 22 is curved by the weight of the rope RP to form a branch BR or trunk of the tree WD. It is possible to hang a rope RP.

Further, in both the rope attachment jig 100 and the rope attachment auxiliary jig 200 in the present embodiment, the tip portion 11 of the operation rod 10 is formed in the male thread portion 11A, and the rope holding portion 20 and the rope locking portion 30 are internally threaded. The form in which the cap bodies 21 and 31 are formed is described, but the present invention is not limited to this form. A male threaded portion (not shown) having a tip 11 of the operating rod 10 formed on the female threaded portion (not shown) and attached to the female threaded portion formed on the tip 11 of the operating rod 10 on the rope holding portion 20 and the rope locking portion 30 (not shown). (Not shown) can also be formed. Further, a known detachable connecting mechanism other than screw fastening can be adopted, or a fixed type can be adopted.

Further, in the present embodiment, the spiral body 22 and the locking tool 32 are both described as a stainless steel striatum member 22A and a striatum, but the stainless steel striatum member 22A and the wire are described. It is not limited to the striatum. The locking tool 32 is not limited to the J-shape in front view, and may be in another shape such as an L-shape in front view. In short, it suffices if the tip TP of the rope RP hung on the target can be locked.

Further, it is also possible to adopt a form in which the modified examples described in the above embodiments are appropriately combined.
