Abstract

PROBLEM TO BE SOLVED: To fold a blade of a sickle so as to raise the portability and safety. SOLUTION: This foldable sickle is obtained by making a blade 1 of the sickle connected to a handle 2 at one site 3 rotatable and rotating an annular part 4 having a groove part through which the blade 1 is passed and is designed so that the blade 1 of the sickle is capable of holding an opened state.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims to enhance portability and safety by folding a sickle blade.

[0002]

2. Description of the Related Art Conventionally, sickles have been widely used for easy mowing of fields and gardens. The sickle is a tool that can cut the grass efficiently by circular motion around the elbow when mowing the grass, and the sickle is located at the circumference of the circular motion, so the speed is fast and the inertia corresponding to that The strength increases, and the heavy sickle makes the arm tired. Therefore, we tried to reduce the weight as much as possible,
It has a neat structure. In order to have such a simple structure, the sickle is fixedly attached at an angle of about 90 degrees to the handle. For this reason, the exposed blade is dangerous and the portability is very poor. Mowing work is not only in flat places, but also in steep mountains and steep hills.If the blade is exposed, it is dangerous to carry around and use nerves to worry about it. It has caused disasters such as stepping off.

[0003]

Under such circumstances, if the blade of the sickle could be folded, the safety and portability would be dramatically improved, and the improvement was strongly desired. For this purpose, the blade of the sickle should be able to be folded, but when using a sickle, it is necessary to widen the blade of the sickle to about 90 degrees. The sickle needs to be lightweight when working, and it is difficult to incorporate the angle holding mechanism in a simple way that does not hinder the work, and it has not been put to practical use .

[0004]

Means for Solving the Problems Now, the structure will be described with reference to FIG. 3. (a) A sickle blade 1 is attached to a sickle handle 2 so as to be rotatable with a wood screw 3, and the sickle blade 1 is When opened, the ring 4 having a groove attached to the tip of the handle 2 of the sickle is rotated with a knob 5 to fix the opening of the blade 1 of the sickle. The device is operated as described above.

[0005]

Next, the operation of the present invention will be described. When the blade 1 of the sickle is folded, if the ring 4 is rotated to close the groove, the blade 1 of the sickle cannot be opened. Next, when opening the blade 1 of the sickle, the annular member 4 is rotated so that the groove is aligned with the portion where the sickle passes, and the blade 1 of the sickle is opened.
open. After that, the groove is closed by rotating the annular member 4 so that the blade 1 of the sickle does not close. This ensures that the opening of the blade 1 of the sickle is maintained. Reference numeral 5 denotes a knob for easily rotating the annular member 4. By rotating the annular member 4 in this manner, the opening of the sickle blade 1 can be reliably fixed.

[0006]

[Experimental example] If it is a small sickle, the ring 4 is 4m in diameter
With a mild steel of about m, a sufficient holding force was exerted on the blade 1 of the sickle. Also, with this degree, there was no problem in the mowing work with the sickle as compared with when the annular object 4 was not attached. In order to prevent the ring-shaped object 4 from easily coming off the handle 2 of the sickle, a part of the sickle for stopping the ring-shaped object 4 is slightly recessed. Since the blade of the sickle opens and closes, attaching the ring 6 to the boundary of the portion having the sickle is effective in preventing danger when the sickle is opened and closed.

[0007]

As described above, by using a sickle that can be folded, safety and portability are dramatically improved.
Farm work becomes comfortable. In the future, the aging of agricultural workers is expected to further increase, and the safety of agricultural work will become even more important. Even in the younger generation, folding sickles are changing the style of agriculture.
