[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a branch bending tool. More specifically, the present invention relates to a branch bending tool capable of forcibly bending a tree branch in horticulture, bonsai, and the like.

[0002]

2. Description of the Related Art Conventionally, in horticulture, bonsai and the like, a wire or string has been wound twice or three times on a tree branch such as a pine tree to pull the wire or string to forcibly bend the branch.

[0003]

However, it is troublesome to wind a wire or string around a tree branch in a double or triple manner, and to unwind the wound wire or string. Especially the bigger the branches,
The greater the bending, the more complicated the operation and the longer the time. For example, when the target value to be bent is large, it is necessary to pull the wire stepwise in several steps, so it is necessary to repeat the work of winding or unwinding a wire or a string around a tree branch.

Further, it is difficult to adjust the force when pulling a branch with a wire or a string, and there is a danger that the branch will be broken if a large force is applied at once. In particular, wires are superior to strings in terms of strength, but there is a risk of damaging tree branches.

The present invention has been made to eliminate the above-mentioned disadvantages of the prior art, and has an object to provide a branch bending tool which can easily bend a tree branch without damaging the tree branch. Is to provide.

[0006]

In order to achieve the above object, a branch bending tool according to the present invention comprises a sliding shaft provided with a thread groove on the outer periphery thereof, a branch shaft fixed to a tip end of the sliding shaft, and A holding plate for holding a part, a handle for rotating the sliding shaft fixed to the rear end of the sliding shaft, a nut screwed into a thread groove of the sliding shaft, and a branch centering on a part of the branch formed comprises of a holder for holding the branch in the front side and a rear side, a connector connecting the retainer and the nut, the
And the connecting tool has a pitch slightly wider than the width of the nut.
A string body having a plurality of stoppers attached,
Gap for inserting the part between adjacent stoppers of the cord body into the slot
And a groove for locking a stopper to the holder is formed.
The distance between the holder and the nut
Is adjustable (claim 1).

Further, another branch bending tool of the present invention includes a support shaft, a holding plate fixed to a tip portion of the support shaft and pressing a part of the branch, a support plate fixed to the support shaft, and one of the branches. A holder for holding the branch on the front side and the rear side of the branch centering on the part, a plurality of stoppers attached at a pitch slightly wider than the width of the support plate, and a string body connecting the holder and the support plate , A gap is formed in the support plate for inserting a portion between adjacent stoppers of the cord body, and a groove for locking the stopper is formed in the holding tool to change the position where the cord body is tied, and The distance to the nut is adjustable (claim 2 ).

[0008]

In the branch bending tool of the present invention, the upper and lower sides of the branch are held by a holder, and a holding plate fixed to a sliding shaft is brought into contact with a part of the branch therebetween, and the handle is rotated. The sliding shaft moves forward with respect to the nut, and a pressing force is applied to a part of the branch via the holding plate. Therefore, for example, when a branch bending tool is attached from above a part of a branch to be bent, the front side and the rear side of the branch are bent upward with respect to a part of the branch. Conversely, when the branch bending tool is attached from below the part of the branch, the front and rear sides of the branch are bent downward with respect to the part of the branch. Also, when a branch bending tool is installed from the right side of a part of the branch, the front and rear sides of the branch are bent to the right with respect to a part of the branch, and conversely, when the branch bending tool is mounted from the left side, the branch is bent. On the other hand, the leading and trailing sides of the branch are bent to the left. Further, since the sliding shaft is screwed to the nut, the branch can be further bent in a state where the branch bending tool is mounted on the branch only by rotating the handle.

And a supporting body fixed to the support shaft and tied with a cord, and is particularly suitable for a tree having a thin branch which can be bent by a human hand.

[0011]

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the appearance of a branch bending tool according to one embodiment of the present invention. The branch bending tool according to the present invention includes a sliding shaft 1, a holding plate 2, a handle 3, a nut 4, holding tools 5, 6, and connecting tools 7, 8.

An external thread 1a is cut on the outer periphery of the sliding shaft 1, and an internal thread (not shown) is screwed into the sliding shaft 1 with a nut 4 cut inside. A holding plate 2 is fixed to the tip of the sliding shaft 1. The holding plate 2 has a curved surface so as to abut on a part of the branch so as to be fitted to the branch 10. A T-shaped handle 3 for rotating the sliding shaft 1 is fixed to the rear end of the sliding shaft 1. Therefore, when the handle 3 is rotated clockwise, the sliding shaft 1
When the handle 3 is rotated counterclockwise, the sliding shaft 1 moves with respect to the nut 4 with respect to the arrow A.
It retreats in the direction opposite to the direction.

The holder 5 has a curved portion 5a for holding the branch 10 at a position on the leading side of the branch 10 with a part of the branch 10 in contact with the holding plate 2 as a center. Further, the holder 6 holds the branch 10 at a position on the rear side of the branch 10 centering on a part of the branch 10 with which the presser plate 2 abuts at the curved portion 6a.

Holes 5b and 6b are formed in the holders 5 and 6, respectively, and bent ends 7a and 8a of connecting rods 7 and 8 functioning as connecting tools are locked in the holes 5b and 6b, respectively. I have. The other ends 7b and 8b of the connecting rods 7 and 8 are similarly bent, and the ring 1 fixed to the bottom of the nut 4
Locked to 1 and 12. As a result, the holders 5, 6 and the nut 4 are connected via the connecting rods 7, 8, so that when the handle 3 is rotated clockwise and the sliding shaft 1 is advanced in the direction of arrow A, the branch 10 becomes the one shown in FIG. It bends as shown by the two-dot chain line.

Further, since the sliding shaft 1 is screwed to the nut 4, when it is desired to bend the branch 10 further, the handle 3 only needs to be further rotated, and the amount of branch bending can be finely adjusted. Further, when bending a branch stepwise, for example,
Since it is not necessary to attach or remove from the branch 10 each time, the branch bending operation is easy.

In FIG. 1, the branch bending tool is mounted on the upper side of the branch 10 to bend the front and rear sides of the branch upward with respect to the branch 10, but the branch bending tool is mounted on the lower side. The front and rear sides of the branch can be bent downward, or the branch bending tool can be attached to the side (from the front to the back of the paper) to bend the front and rear sides of the branch to the front of the paper. it can. On the contrary, when the branch is mounted, the front and rear sides of the branch can be bent to the back side of the paper.

Here, the sliding shaft 1, the holding plate 2, the handle 3, the nut 4, the holding members 5, 6, the connecting members 7, 8,
The rings 11 and 12 are made of synthetic resin so as not to rust. In addition, you may use the thing made from stainless steel.
The handle 3 only needs to rotate the sliding shaft 1, and may be, for example, a wing nut or a ball handle.

FIG. 2 shows the appearance of a branch bending tool according to another embodiment of the present invention. The same parts as those of the branch bending tool shown in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

The nut 14 is, like the nut 4, the sliding shaft 1.
, But the gaps 14a, 1 connecting the top and bottom surfaces thereof
4b is formed. In the gaps 14a and 14b, a plurality of stoppers 19 and 2 attached at a predetermined interval, that is, a pitch slightly larger than the width L between the upper surface and the bottom surface of the nut 14.
The portions between the adjacent stoppers of the cords 17 and 18 having 0 are respectively inserted.

The size of the plurality of stoppers 19, 20 is larger than the width of the gaps 14a, 14b. Therefore, when the cords 17 and 18 are inserted into the gaps 14a and 14b, the stoppers are locked on the upper surface and the bottom surface of the nut 14, so that the cords 17 and 18 are fixed to the nut 14.

On the other hand, stoppers 1
Holes 15b and 16b larger than the sizes of the holes 9 and 20 are formed.
Grooves 15c and 16c each having a width smaller than the size of 9 and 20 are formed, respectively. Therefore, the stoppers are provided for the grooves 15c and 16c.
c, the strings 17, 18 are held by the holders 15, 16
Fixed to As a result, the nut 14 and the holders 15, 1
6 is connected via string bodies 17 and 18.

The gaps 14a and 14b are cut
Since the cords 17 and 18 are formed in a direction perpendicular to the direction in which the cords 17 and 18 extend, the cords 17 and 18 do not come off the gaps 14a and 14b when the nut 14 and the holders 15 and 16 are connected. Although two gaps 14a and 14b are formed, two strings 17 and 18 may be inserted into one gap. Further, a plurality of stoppers 19, 20 and a string body 17,
Reference numeral 18 is made of a synthetic resin, and the cord bodies 17 and 18 have flexibility. Therefore, the cord bodies 17 and 18 are strong against bending.

According to this, the gaps 14a of the nut 14,
The insertion positions of the cords 17 and 18 with respect to the holding members 15 and 16 can be freely adjusted.
Since the mounting position of the nut 8 can be adjusted freely, the nut 14
And the length of the holder 15 and the length of the nut 14 and the holder 16 can be changed separately. Therefore, for example, when the thickness of the front side and the thickness of the rear side of the branch are considerably different, or when the branch is not straight, the sliding shaft 1 is adjusted so that the sliding shaft 1 is perpendicular to the branch to be bent. This is effective when the pushing force is concentrated in a direction perpendicular to the branch 10. In addition, the length can be easily adjusted because of the insertion method.

FIG. 3 shows the appearance of a branch bending tool according to another embodiment of the present invention. The same parts as those of the branch bending tool shown in FIG. 2 are denoted by the same reference numerals, and description thereof will be omitted.

A holding plate 2 for pressing a part of a branch is fixed to a tip end of the support shaft 21, and a support plate 24 having gaps 24a and 24b formed at the rear end thereof for inserting cords 17 and 18 therethrough.
Is fixed. The appearance of the support plate 24 is the same as that of the nut 14 shown in FIG. Therefore, a plurality of stoppers attached at a slightly wider pitch than the width L ₂ of the support plate 24 (same as the width L of the nut 14) are fixed to the strings 17, 18 connecting the holders 15, 16 and the support plate 24. Have been.

According to this, a part of the branch is held down by the holding plate 2 fixed to the support shaft 21 and the front and rear sides of the branch are bent in a bow shape by a human hand, and the holders 15, 16 are held. And the support plate 24 fixed to the support shaft 21 are connected by strings 17 and 18, and the stopper 1 adjacent to the strings 17 and 18 is secured to secure the position.
The branch 10 is bent by inserting the portion between 9 (20) into the gaps 24a, 24b. Particularly suitable for trees with thin branches that can be bent by human hands.

The length of the nut 14 or the support plate 24 and the length of the holders 15 and 16 can be adjusted by adjusting the length of the string 1 with a stopper.
The connection is performed in steps 7 and 18, but the connection is not limited to this, and the connection may be made using a member whose length can be adjusted by, for example, an extendable connection rod or a screw.

[0028]

As described above, according to the branch bending tool of the present invention, the upper and lower sides of the branch are held, and the holding plate fixed to the sliding shaft is advanced to a part of the branch between the upper and lower branches to advance one of the branches. Since the branch is bent in an arc shape by applying a force to the portion, the branch can be easily bent without winding or unwinding a wire or a string around the branch as in the related art. Therefore, the tree branches are not damaged by the wire.

Further, since the sliding shaft is screwed to the nut, when it is desired to bend the branch further, the handle only needs to be further rotated, and the amount of branch bending can be finely adjusted. Furthermore, since it is not necessary to attach a branch bending tool to a branch or to remove it from a branch each time, for example, when bending a branch in a stepwise manner, the branch bending operation is easy.

By varying the size of the branch bending tool according to the invention, smaller ones can be used for bonsai, while larger ones can even bend large tree branches.

Also, since the length of the connecting member is adjustable,
The length between the nut and the holder can be changed. Therefore, for example, when the thickness of the front side and the thickness of the rear side of the branch are considerably different, or when the branch is not straight, the sliding shaft is adjusted so that the sliding shaft comes at a right angle to the part of the branch to be bent and pressed. This is effective when the force is concentrated at right angles to the branches.

Further, the connecting member is a cord body having a plurality of stoppers attached at a pitch slightly wider than the width of the nut, forming a gap for inserting a portion between adjacent stoppers of the cord body into the nut, and Since the groove for locking the stopper is formed, the adjustment of the length of the connecting member is easy and the handling is convenient.

According to another branch bending tool of the present invention, a part of the branch is held down by a holding plate fixed to the support shaft, and the front side and the rear side of the branch are bent in an arc shape by a human hand. Since the condition can be ensured, it is particularly effective for a tree with a thin branch that can be bent by a human hand. In this case, it is only necessary to fix the support plate to the support shaft, and it is not necessary to cut a thread groove and screw the support plate to the support shaft in order to make it slidable. A tool is provided.
