DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sickle, and more particularly to a sickle and a scythe, which can cut plants such as grass and bush as well as a conventional sickle. It relates to a sickle that is not cut by a blade even when a part of the human body such as a human body or a foot touches it.

[0002]

2. Description of the Related Art Conventionally, a main body 101 of a sickle has a substantially crescent shape in a plan view, and a blade 102 is formed on one side thereof.
The tip 103 of the sickle was sharply pointed, and a handle 104 was attached to the lower end of the other end of the sickle. (See FIG. 12) The saw blade used for rice harvesting has a blade of a sickle body 106 formed in a saw-shaped saw blade 107, and the tip of the saw blade 107 is also sharpened. 108 was also sharply pointed. (See FIG. 13) Naturally, the blades 10 of
2, the blade 107 of the saw blade 106, or the tip 103, 1 of the sickle
08 was also formed on the outer periphery in a bare state.

[0003]

As described above, the sickle (including a saw sickle) as described above is, of course, a sickle body 101,1.
The accident that the limbs touched the blade 102, the saw blade 107, and the tips 103 and 108 of the sickle formed in a bare state on the outer periphery of 06 and were injured (cut or stab wound) frequently occurred. In view of the above drawbacks, the problem to be solved by the present invention is to form a plurality of cutouts on one side of the sickle body and form a blade or saw blade inside the cutouts,
Even if a part of the body touches the place where the blade on one side of the sickle body is provided,
By forming the sharp tip of the sickle (including a saw blade) as an arc-shaped outer periphery without directly touching the blade, even if a part of the human body such as a limb touches one side or the tip of the sickle body by mistake An object of the present invention is to provide a safe sickle in which a blade or a sharp tip is not formed on the outer periphery of a sickle body so as not to receive a cut or, in other words, to receive a cut.

[0004]

The sickle according to the present invention solves the above-mentioned problems and is as follows. The sickle according to claim 1 includes a sickle body, a notch formed on one side of the sickle body, and a blade formed inside the notch.

According to a second aspect of the present invention, the sickle includes a sickle body and an arc-shaped tip formed at one end of the sickle body.

According to a third aspect of the present invention, there is provided a scythe including a scythe body, a plurality of notches formed continuously at one side of the scythe body, or formed at arbitrary intervals, and a blade formed inside the notches. An outer periphery formed at one end of the scythe body has an arc-shaped tip.

The scythe of claim 4 is characterized in that the blade according to claim 1 or 3 is not formed at least in the vicinity of the opening of the notch.

[0008]

Since the scythe has the above-mentioned structure, even if the scythe body is grasped by hand, the blade is not formed at least in the vicinity of the opening of the notch and on the outer periphery of the scythe body. Since the blade is not exposed on the outer periphery of the sickle body, even if the sickle is accidentally touched, the blade does not touch a part of the human body and does not damage the human body. Also, the tip of the sickle body,
Since it is formed as an arc-shaped outer periphery, even if a human body hits the tip, no injury is caused.

[0009]

A description will be given with reference to FIGS. Like the conventional sickle, the sickle main body 1 is formed in a substantially crescent shape (not limited to a crescent shape) in a plan view. A semicircular cutout 2, 2 (the shape of the cutout is not limited to a semicircular shape as described later) is provided on one side of the sickle body 1 at a predetermined interval (this interval may be arbitrary). To be connected in series. Blades 3, 3 are formed along the inside of these semicircular cutouts 2, 2. It is important that the blades 3 are not formed at least in the vicinity of the openings of the notches 2. Therefore, between the notches 2 and 2, the protruding portions 4 and 4 protruding from the blade 3 toward the outer periphery of the sickle main body 1 are formed, and no blade is formed on the protruding portion. One end of the sickle body 1, that is, the outer periphery of the tip 5, is formed as an arc-shaped outer periphery, that is, a curved line. The other end of the sickle main body 1 is bent by folding lines 6a and 6b in the longitudinal direction of the sickle main body 1, and has a shape in which the sickle main body 1 and the handle 7 are connected with a step when the handle 7 described later is gripped. (Although not shown, instead of a step, it may be connected in a curved line like a conventional mowing scythe, and its shape does not matter.) A handle 7 is attached to the other end of the bent scythe body 1 Attach. Since the scythe has the above configuration, the protruding portions 4, 4 protruding between the respective notches 2 are provided.
Is formed, and the blades 3 are formed only on the inner surfaces of the notches 2 and 2, and the blades 3 are not formed at least in the vicinity of the openings of the notches 2 and 2 and the outer periphery of the sickle body 1. For example, even if the scythe body 1 is grasped by hand or touched by mistake,
Even if it touches, a part of the human body does not touch the blade 3 and is not cut, so that it is safe. Therefore, even if a part of the human body touches one side of the sickle body 1 during work, handling of the sickle, or a child or infant mischieving the sickle, the blade 3, 3 is not touched, so there is no possibility of injury from the blade of a sickle (including a saw blade). There is no.

[Embodiment 2] A different embodiment of the present invention shown in FIG. 7 will be described. In the following description of the present embodiment, the same components as those of the already described embodiment of the present invention are denoted by the same reference numerals, and redundant description will be omitted.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The scythe body of the above embodiment was prototyped from metal in the shape shown in FIGS. 1 and 9 and the scythe body 1 was gripped by hand. Good results were obtained without cutting hands.

[0017]

Since the sickle according to the present invention has the above-described structure, it has various effects as listed below. Claim 1 is that the blade is formed inside the notch,
Since there is a protrusion between the notch and the notch, even if you hold the scythe body with your hand, the blade inside the notch does not touch the hand, so a scythe that is not cut by the blade is obtained. Can be Also, even if the side with the blade of the sickle body is mistakenly applied to the human body, there is a protrusion between the cutouts, so the cutout is cut off by the blade because the protrusion does not hit the human body because it is blocked by the protrusion. You can get a sickle that doesn't receive it.

In the sickle according to the second aspect of the present invention, since the tip of the sickle body is formed in an arc shape, a sickle that is not stabbed even when the tip hits a human body can be obtained.

A sickle according to a third aspect of the present invention has the configuration of the sickle of the first and second aspects of the invention, and also has the effects of the sickle of the first and second aspects of the invention. Therefore, even if the sickle hits the human body, the blade does not hit the human body, so that a sickle that is not cut by the sickle blade can be obtained.

According to the fourth aspect, the same effect as that of the sickle according to the first aspect is obtained. That is, since the blade is not formed at least in the vicinity of the opening of the notch, even if the sickle body is gripped or the sickle hits the human body, the blade does not hit the human body, so the sickle blade does not receive a cut. You can get a sickle.
