Abstract

PROBLEM TO BE SOLVED: To provide a knife with reduced harm to a human body. SOLUTION: A knife 1 is provided with a handle 2 and a blade body 3 extending from one tip of the handle 2. The width of the body 3 is formed wider than that of the handle 2 and one side edge 3a of the body 3 is projected from the handle 2. The tip part 4 of the body 3 is formed to be nearly semi-circular. In addition, at one side edge 3a of the body 3, a blade part 5 nearly in parallel with the longitudinal direction of the handle 2 is formed by extending to a base tip edge 6a from a position separated in the direction of the base tip by a distance d1 from a tip edge 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knife.

[0002]

2. Description of the Related Art Generally, a knife has a blade portion formed in a tapered shape from a distal end edge on one side of a blade to a proximal end edge.

[0003]

In such a knife, there is a high possibility that the tip of the blade may cause harm to the human body when the knife is accidentally dropped or swung, or when the blade is put in a sheath. Was.

[0004] The present invention has been made to solve the above problems, and an object of the present invention is to provide a knife capable of reducing harm to a human body.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, in a knife provided with a handle and a blade, the width of the blade is formed wider than the width of the handle. The gist of the invention is that a blade portion extending in a direction substantially parallel to a longitudinal direction of the handle is formed on the one side edge of the blade except for a tip portion of the blade.

According to a second aspect of the present invention, in the knife of the first aspect, a blade is formed on the blade except for a base end thereof.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, the knife 1 includes a handle 2 and a blade 3 extending from one end of the handle 2. The width of the blade 3 is formed wider than the width of the handle 2, and one side edge 3 a of the blade 3 projects from the handle 2. The tip 4 of the blade 3 is formed in a substantially semicircular shape. Further, on one side edge 3a of the blade 3, a blade portion 5 which is substantially parallel to the longitudinal direction of the handle 2 is formed from a position separated in the proximal direction by a distance d1 from the distal edge 4a to the proximal edge 6a. Have been. The knife 1 thus formed is used like a general knife, as shown in FIG. When not in use, the blade 3 is stored in a sheath 7 shown by a two-dot chain line in FIG.

As described above, according to the present embodiment, the following effects can be obtained. (1) Since the blade portion 5 is not formed at the tip portion 4 of the blade 3, if the knife 1 is dropped by mistake, the knife 1 does not stick into the dropped portion. Further, even when the blade 3 cannot be stored by mistake when storing the blade 3 in the sheath 7, the knife 1 does not stick into the hand holding the sheath 7. Therefore, the harm that the knife 1 exerts on the human body can be suitably reduced.

(2) In addition to the fact that the blade 5 is not formed at the tip 4 of the blade 3 and that the blade 5 is formed in a direction parallel to the axis of the handle 2, an arrow is shown in FIG. As shown by, when the knife 1 is swung around the fulcrum, the blade portion 5 does not face the outer peripheral direction. Therefore, even when the knife 1 is swung, harm to the human body can be reduced.

(3) Since the side edge 3a of the blade 3 on the side where the blade portion 5 is formed is formed so as to protrude beyond the handle 2, the blade portion 5 can be cut by pressing the blade portion 5 against a cutting board or the like. Also,
For example, when the tip 4 is pressed against the cutting board to perform chopping, it is possible to preferably suppress the cutting board from being damaged by the tip 4.

(4) Since the tip 4 of the blade 3 is formed in a substantially semicircular shape, the blade 3 can be easily accommodated in the sheath 7. The above embodiment may be modified as follows.

In the above embodiment, the blade portion 5 is formed from a position separated from the distal edge 4a in the proximal direction by the distance d1 to the proximal edge 6a, but as shown in FIG.
The blade portion 5 is formed between a position separated from the distal edge 4a in the proximal direction by a distance d1 and a position separated from the proximal edge 6a in the distal direction by a distance d2. In this way, in a state where the grip 2 is gripped, the risk of the base edge 6a being harmful to the gripped hand can be reduced appropriately.

Further, as shown in FIG. 3, the corner of the base edge 6a is further dropped. In this way, the risk of the base edge 6a affecting the human body can be reduced more suitably. Even if this is embodied in the above embodiment, the same effect can be obtained.

While the embodiments have been described above, technical ideas other than the claims that can be grasped from the embodiments will be described below together with their effects. (1) The knife according to claim 1 or 2, wherein the tip of the blade is formed in a semicircular shape.

With this configuration, it is possible to further reduce the danger that the blade tip exerts on the human body. (2) The knife according to any one of (1), (2), and (1), wherein a corner of a base end of the blade is dropped.

[0016] In this manner, in the gripping state, the risk of the base end edge exerting on the gripped hand can be reduced more suitably. (3) The knife according to any one of (1), (2), (1) and (2), further comprising a sheath for accommodating the blade.

In this way, it is possible to prevent harm to the human body when not in use and to prevent the knife from being stuck in the hand holding the sheath when the blade is stored in the sheath.

[0018]

According to the first aspect of the present invention, since the blade is not provided with a blade at the distal end thereof, it is possible to reduce the harm of the distal end to the human body. Further, since the blade is formed in a direction substantially parallel to the longitudinal direction of the handle, the blade does not face the outer peripheral direction. Therefore, even when the blade is swung, harm to the human body can be reduced.

According to the second aspect of the present invention, in a state where the handle is gripped, it is possible to preferably reduce the danger of the base end edge to the gripped hand.
