Detailed Description of the Invention

[0001]

The present invention relates to a binding device.
More specifically, the present invention relates to a binding device for winding and binding a chain or the like around a constrained object.

2. Description of the Related Art Hitherto, in forests and plantations in various places, damage to trees caused by landslides caused by heavy rain and heavy snow pressure has been enormous. At present, it has been left in such a bad state, such as cracking and breaking.
It is extremely difficult to cut and organize this, because the severed part of the trunk is severely split and dangerous.

[0005] That is, as shown in FIG. 5, a tree W which is in a half-lodged state due to a landslide or snow cover has a split part (a crack in the longitudinal direction of the tree in this figure) P (FIG. 5A )), And the split part P is often in a partially cut state (T part in FIG. 5B). In addition,
FIG. 5B shows a state in which snow is accumulated on the tree W.

Then, when the split part is cut with a saw, the split part breaks and pops. For example, the tree shown in FIG. 5A is in the state shown in FIG. 5B, and the tree shown in FIG. 5B is further split and burst. In order to avoid such a situation, the vicinity of the splitting portion of the tree as described above may be bound tightly around the entire circumference in advance. This prevents the split part from popping during sawing. In such a case, attempting to bind with a wire rope or the like would be a rather cumbersome operation, resulting in a large loss in time and a difficulty in transporting equipment such as the wire rope.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a flexible binding member is wound around a binding target such as a tree and is irreversibly rotated. Since it is configured so that it can be moved so as to bind the tree through the force transmission mechanism, it can be easily attached to the target tree, etc., it can be tied quickly with a light force of a person, and it is possible to safely cut trees. It will be possible.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a binding device according to the present invention.

FIG. 1 is a perspective view showing an embodiment of the binding device according to the present invention, FIG. 2 is a partially cutaway front view of the binding device of FIG. 1, and FIG. FIG. 4 is a perspective view seen from a different direction, and FIG. 4 is an explanatory view showing one use example of the binding device of FIG.

FIGS. 1 and 2 show a main body 2 of a binding device 1.
And a part of the roller chain 3 are shown. Reference numeral 4 denotes a handle for operating the binding device 1. As shown in FIG. 2, the handle 4 is detachably attached to a shaft 6 a of a worm gear 6 of a worm gear mechanism 5 provided inside the main body 2 by a thumb screw 7. The shaft 6a is rotatably supported by a pair of bearings 8. On the other hand, the shaft 9a of the worm wheel 9 has a sprocket 10
Are connected. Therefore, by rotating the handle 4 (arrow A), the sprocket 10 is rotated (arrow B).

Although not shown, the shaft 9a of the worm wheel 9 is also supported by a bearing.

In FIG. 1, a roller chain 3 has a base end pivotally attached to a main body 2 using a hinge 11. The other end of the roller chain 3 is engaged with the sprocket 10. 12 is sprocket 1
A guide plate for guiding the roller chain 3 engaged with 0 so as not to come off, and is swingably attached to the main body using a hinge 13. Furthermore, guide plate 1
2 is the working position (position where the roller chain can be guided)
A lock member 14 that can be fixed to the main body 2 is attached to the main body 2. By doing so, the guide plate 12 can be retracted upward when the roller chain 3 is engaged with the sprocket 10 and when the roller chain 3 is removed from the sprocket 10.

As shown in FIG. 1, when the handle 4 is rotated clockwise (arrow A) in the binding device 1, the roller chain 3 moves in the direction of its tip (arrow C) to form a loop L formed by the roller chain 3. It becomes smaller and can bind things. In this case, the surface 2 a of the main body 2 forms a plane parallel to the sprocket 10 and guides the roller chain 3.

In the figure, reference numeral 15 denotes an abutting portion for abutting against an object to be tied, and the tying device 1 of this embodiment has a curved surface substantially along the outer peripheral surface thereof for use on a tree trunk.

FIG. 3 is a view of the binding device 1 as viewed from the side opposite to FIG. In the figure, reference numeral 16 denotes a fixing pin, which is attached to the main body 2 so as to be movable in the axial direction. The fixing pins 16 are used for positioning and fixing the main body 2 by driving the binding device 1 into a tree when attaching the binding device 1 to the tree. It is not necessary to use the present binding device 1 when using it for objects other than trees.

FIG. 4 shows an example of use of the binding device 1. In this use example, a tree in a state as shown in FIG. As shown in the figure, the fixing pin 16 is hit against the split part P of the trunk of the tree W to fix the main body 2 to the tree. Thereafter, the roller chain 3 is wound around the trunk and is engaged with the sprocket 10. Then, the handle 4 is rotated to operate the split portion P.
(FIG. 4A). In this way, the connective tissue of the tree is not destroyed, so that it does not tear off from the cut part and burst. Next, the lower part of the binding portion in the trunk is cut by the saw S (FIG. 4B).

When used for the partially cut tree W shown in FIG. 5 (b), the upper part of the cut part T is tied up to prevent further splitting and cutting.

In this embodiment, as shown in FIGS. 1 and 3, the roller chain 3 and the sprocket 10 are arranged one by one on one side of the main body 2, but the present invention is not limited to this. Instead, the roller chain 3 and the sprocket 10 may be provided on both sides of the main body 2. In that case, the position of the fixing pin 16 may be on the side opposite to the handle mounting portion of the main body 2. By doing so, the two roller chains can be operated by one handle 4, so that it is possible to tighten more strongly.

The present binding device 1 cuts a large-diameter tree by changing the length and tension of the roller chain or the diameter of the sprocket, in addition to the above-mentioned tree binding.
It is also easy to cause a tilted tree or to cut in a desired direction.

Further, according to the present binding device 1, in addition to being applied to a tree in a laid state, it can be applied as an easy binding device to various objects.
