Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping device which can be suitably used for cutting off a lower branch such as a cedar or a cypress (referred to as pruning).

[0002]

2. Description of the Related Art After planting cedars and cypresses at a predetermined interval, it is necessary to remove branches below the trees themselves when they have an appropriate size. In the work of cutting off the branches, tools such as a hatchet, a sickle and a saw are conventionally used.

[0003]

However, since tools such as a hatchet, a sickle and a saw have a short handle, it is necessary to use a ladder or the like, which is extremely troublesome. Therefore, it is possible to attach an upper sickle to the tip of the long handle and remove the branches at a higher position from the ground.However, since the blade is cut only from above the branch to be cut, a thick branch is used. In this case, there is a problem that cutting is extremely difficult. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a wiping tool that can insert a blade in a vertical direction (including bottom to top and top to bottom) with respect to a branch to be cut. And

[0004]

According to a first aspect of the present invention, there is provided a wiping tool having a blade main body and a handle attached to a base end side of the blade main body. An upper cutting edge and a lower cutting edge are provided vertically, and the upper and lower cutting blades face each other. As described above, since the pruning tool according to the present invention includes the upper cutting blade and the lower cutting blade vertically opposed to each other, the upper side of the branch to be cut is the upper cutting blade.
The lower side will be cut by the lower cutting blade. Here, in the pruning tool according to the present invention, it is preferable that the upper cutting blade and the lower cutting blade are each bent in a curved shape, whereby the branch to be cut is brought into the center of each blade portion. Can be cut off.

[0005] In the wiping tool according to the present invention, it is preferable that the interval between the upper cutting edge and the lower cutting edge has a distance of, for example, 20 to 70 cm. 20cm spacing between upper and lower cutting blades
If the value is less than the above range, it becomes difficult for the branches to fit between the upper cutting edge and the lower cutting blade, and the inertia force applied to the upper cutting edge and the lower cutting edge by moving up and down cannot be increased. On the other hand, if it exceeds 70 cm, the stroke of vertical movement when cutting the target object with the upper cutting blade and the lower cutting blade becomes long, and the work becomes difficult. Still further, in the pruning tool according to the present invention, the handle is 3 to 1 with respect to the blade main body.
It is preferable to bend and mount within a range of 5 degrees.
Thus, the pruning can be performed from a position slightly away from the branch to be cut.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, embodiments of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. Here, FIGS. 1 (A) and 1 (B) are a front view and a side view, respectively, of a pruning tool according to an embodiment of the present invention.
FIG. 2 is an explanatory diagram showing a use state of the same branching tool.

As shown in FIG. 1, a wiping tool 10 according to an embodiment of the present invention has a blade main body 11 made of steel and a wooden handle 12 provided at a base thereof. The blade body 11 has an upper cutting edge 13 on the upper side and a lower cutting edge 14 on the lower side. The blade portion 15 of the upper cutting blade 13 is curved downward so that the center position of the radius of curvature is on the lower side.
Further, the blade portion 16 of the lower cutting blade 14 is curved upward so that the center position of the radius of curvature is on the upper side. That is, the blade portions 15 and 16 of the upper cutting edge 13 and the lower cutting edge 14 face each other. The average distance between the upper cutting edge 13 and the lower cutting edge 14 is 2
It is about 0 to 70 cm (more preferably about 40 to 60 cm). The total weight of the wiping tool 10 is preferably 1.5 to 3 kg. The reason for this is that if the wiping tool 10 is too light, the inertial force (momentum) is lost, and if the wiping tool 10 is too heavy, it is difficult to perform the work. , 1
The present invention is also applicable to ５5 kg).

The lengths of the upper cutting edge 13 and the lower cutting edge 14 (blade portions 15, 16) are about 15 to 30 cm, respectively.
The invention applies whether it is longer or shorter. In addition, the upper cutting edge 13, the lower cutting edge 14, and the connecting member 17 for connecting them are integrated. At the base of the blade main body 11 having these, a handle tip mounting portion 18 having a square cross section is provided. The handle tip attaching portion 18 is attached to the connecting member 17 at an inclination angle (α) of about 3 to 15 degrees.
The tip of the wooden handle 12 fits into the handle tip mounting portion 18, and the attached handle 12 is 3 to 15 with respect to the blade body 11.
It will be bent and installed. Thereby, the blade main body 11 can be arranged obliquely to the branch to be cut, and the branch can be cut from the root portion of the branch.

Next, a method of using the wiping tool 10 according to one embodiment of the present invention will be described with reference to FIGS. First, the branch 20 to be cut is arranged between the upper cutting edge 13 and the lower cutting edge 14. And
When the whole is pushed up with the handle 12, the lower cutting blade 14
A cut 22 is formed in contact with the lower side of 0. next,
When the whole is pressed down with the handle 12, the upper cutting blade 13
A cut 21 is formed on the branch 20 against the upper side of the zero. By repeating this operation, even a thick branch can be cut off. Here, since the handle 12 is inclined with respect to the blade main body 11, the blade main body 11 can be applied to the side closer to the trunk 23 to cut, for example, the position P in FIG. In this case, since the wiping tool 10 has a certain weight, the branch 20 can be cut by adding inertia at the time of vertical movement.

In the above embodiment, the upper cutting blade 13,
The lower cutting blade 14 has a curved shape (for example, a crescent shape), but if the upper and lower blade portions are opposed to each other, a straight line or other shapes are included in the present invention. Also,
The upper cutting blade and the lower cutting blade can be detachably attached to the connecting portion, and in this case, the sharpening operation becomes easy. In the above embodiment, the handle 12 is made of wood. However, the present invention is applicable to a light metal such as aluminum, a reinforcing fiber such as carbon fiber, or a plastic. In the pruning tool according to the above-described embodiment, it is possible to provide a removable weight according to the size of the branch and the operator, whereby the weight of the entire pruning tool can be adjusted.

[0012]

According to a first aspect of the present invention, there is provided a wiping tool having a blade main body and a handle attached to a base end side of the blade main body. The upper and lower blades are provided on top and bottom, and the upper and lower cutting blades are facing each other. Can cut branches. In particular, in the wiping tool according to claim 2, since the upper cutting edge and the lower cutting edge are each bent in a curved shape, they act to guide the branch to be cut inward,
Branches can be cut more reliably. According to the third aspect of the present invention, since the distance between the upper cutting edge and the lower cutting edge has a distance of 20 to 70 cm, the branch can be fitted therein. According to the fourth aspect of the present invention, since the handle is bent and attached to the blade body within a range of 3 to 15 degrees, the branch can be further cut to the root.
