Hereinafter, examples of embodiments of the present invention will be described with reference to the drawings. Components common to the following embodiments (and modifications) may be denoted by the same reference numerals as those described above, and description thereof may be omitted. In addition, when referring to the shape, positional relationship, etc. of components, etc., unless otherwise specified or in principle clearly considered otherwise, etc. that are substantially similar or similar to the shape, etc. shall include

1A and 1B are diagrams showing an example of a fishing hook according to the present invention, and are (a) a front view and (b) a left side view. X indicates the horizontal direction (horizontal direction), Y indicates the vertical direction (vertical direction), and Z indicates the thickness direction (front-rear direction) (the same applies to each drawing below).

The fishing hook 1 of the present invention is a series of fishing tackles having a substantially J-shape or "-" shape. A fishhook 1 has a trunk portion 2 , a hook tip portion 3 , and a curved portion 4 having a curved shape between the trunk portion 2 and the hook tip portion 3 . The bending portion 4 has a waist bend 41 on the body portion 2 side and a tip bend 42 on the needle tip portion 3 side. The waist bend 41 and the forward bend 42 may have different degrees of curvature, as shown, or they may be the same.

The hook 1 may also have a timoth 5 that follows the body 2 . The chimoto 5 is a portion for tying a fishing line (line, Harris), and is wider than the trunk 2 (in this case, front-to-rear width). The chimoto 5 may be formed in a plate shape as a so-called "beating" as shown in the drawing, may be formed in a ring shape as a so-called "ring", or may be formed in other shapes.

The fishing hook 1 may also have a hook (ike) 6 . As an example, the calyx 6 is provided on the inner side of the tip bend 42 and has a shape that is pointed obliquely downward (downward and inward). In the present application, the term “inner side” refers to the side of the fishhook 1 where the body portion 2 and the hook tip portion 3 face each other, in other words, the inside of the curved shape of the curved portion 4 (futokoro). In addition, when the hook 6 is formed by cutting and raising a part of the material of the fishing hook 1, the cut-out portion (not shown in the following figures) of that amount is not shown in the tip bend 42 marks) remain. Kaesi 6 may be formed on other portions of curved portion 4 . The fishing hook 1 may be configured without the hook 6, that is, a so-called "thread hook".

A conventional fishhook has a sharp point as indicated by the dashed line in the drawing (see also the dashed line in FIG. 2). In other words, conventional fishhooks are conical with a pointed tip, gradually tapering in diameter as they go forward, and finally forming a point. Therefore, it not only easily sticks into the mouth of the fish, but also easily sticks into the user's hand. Even if the user is careful, he or she may be stung and injured when sticking the bait on the hook or removing the hook from the fish or the like that has been caught.

SUMMARY OF THE INVENTION An object of the present invention is to provide a fishing hook that is less likely to cause injury. In the fishing hook 1 according to the present invention, the tip 31 of the hook tip portion 3 is formed not as a point but as a plane. Alternatively, it is formed in a streaky shape as shown in FIG. 12, which will be described later. By being formed in this way, the fishing hook 1 of the present invention sticks to fish and the like, but is less likely to stick to the user and less likely to injure the user.

The epidermis of human skin has a stratum corneum on the outermost surface, and the stratum corneum is particularly thick on the palm, fingertips, and the like. If the tip 31 of the needle tip portion 3 is made planar or streaky, it is difficult for even a fish or the like to pierce the stratum corneum, and injury is less likely to occur.

Some users, such as beginners who have just started fishing, children, and elderly people who have difficulty seeing near objects, place more importance on safety. Also, even among experienced fishermen, there is a desire to enjoy the process of fishing without getting injured, rather than the results of fishing. The fishing hook 1 of the present invention emphasizes safety and responds to such demands.

The hook tip portion 3 of the fishing hook 1 of the present invention and the method of manufacturing the fishing hook 1 will be described in detail below.

<Embodiment 1>
FIG. 2 is a view showing an example of the needle tip portion of Embodiment 1, and is a partially enlarged view of FIG.

As shown in FIG. 2(a), the needle tip portion 3 is a portion above the position corresponding to the upper end of the base of the barb 6 (the position of the dashed-dotted line in the drawing, which is the same in each figure below). The portion at this position is hereinafter also referred to as the “base end” of the needle tip portion 3 . Note that the needle tip portion 3 may be any portion that includes the tip 31, and the definition is not limited to this. If the fishhook 1 does not have the barb 6, the hook tip 3 is the part corresponding to the above. The illustrated needle tip portion 3 is curved slightly inward as a whole, but it may extend straight as shown in FIG. 7, which will be described later, or may be curved slightly outward.

As an example, the tip 31 of the needle tip portion 3 is formed into a curved surface as shown in the drawing. Although not shown here, the tip 31 of the needle tip 3 may be formed flat. A portion of the needle tip portion 3 other than the tip 31 is not particularly limited, and may have a known shape.

FIG. 3 is a flow chart showing an example of the manufacturing method of the fishing hook of the present invention.

For the fish hook 1, for example, a steel or stainless steel metal wire material having a circular cross section is used as in the conventional case. The thickness of the wire material is not limited, and is determined according to the target fish species and the like. As an example, one having a diameter of about 1 mm to 5 mm, for example, about 2 mm to 3 mm is used.

The wire material is first cut to a predetermined length in the cutting step S1. The cut wire material is processed into the shape of the needle tip portion 3 by polishing or the like in the pointed step S2.

Unlike the conventional needle tip portion 3, the tip 31 is processed to have a curved surface or a flat surface instead of a sharp conical shape in the sharpening step S2. If the tip 31 has a curved surface, it is necessary to grind the portion following the tip 31 into a tapered shape and grind the tip 31 into a curved surface, but if it is flat, the grinding of the tip 31 can be omitted.

After that, the timbres 5 are formed by pressing or the like in the timbre forming step S3, the ridges 6 are formed by cut-raising or the like in the hem forming step S4, and the waist bending 41 and the front bending 42 are formed in the bending step S5, followed by post-processing. Proceed to step S6. The post-treatment step S6 includes heat treatment (quenching/tempering), chemical polishing, plating, and the like. Incidentally, in the case of the fishhook 1 without the barb 6, the barb forming step S4 is omitted.

The fishhook 1 of the present embodiment differs from the conventional one in the polishing process in the point step S2, but can be easily manufactured with the existing equipment because the process is generally the same as the conventional process. In addition, since the amount to be removed in the polishing process is smaller than in the conventional art, it can be manufactured in a shorter period of time and at a lower cost than in the conventional art.

Although it is conceivable to use a ready-made conventional fish hook to cut off the sharp tip and perform processing such as polishing, it is difficult to perform processing with high accuracy because it is after heat treatment. Moreover, rust etc. will generate|occur|produce.

FIG. 4 is a flowchart showing another example of the method for manufacturing a fishing hook according to the present invention. Fishing hooks are often manufactured in large lots, and in some cases it is difficult to manufacture in small lots in terms of cost. According to this example, the fishing hook 1 can be easily manufactured even in small lots.

Specifically, in this example, the cutting step S1, the cusp step S2, the tip forming step S3, the maple forming step S4, the bending step S5 and the post-processing step S6 are completely the same as in the conventional case. A difference from the conventional method is that a retouching step S7 is added between the cusp step S2 and the chimoto formation step S3. Note that the retouching step S7 is not limited to this, and may be added after the peaking step S2 and before the post-processing step S6.

In the modification step S7, the needle tip portion of the filament material processed into a sharp conical shape in the pointed head step S2 is modified so that the tip thereof has a curved surface or a flat surface. Although not particularly limited, for example, techniques such as polishing and cutting are used for retouching.

As described above, the method for manufacturing the fishing hook 1 includes at least the step of processing (S2) or modifying the tip of the cut wire material into a curved surface or a flat surface (S7), and a step (S6) of performing post-treatment including heat treatment on the strip.

<Modification 1 of Embodiment 1>
5A and 5B are views showing an example of the needle tip portion of Modification 1 of Embodiment 1, and are (a) a front view of the example, (b) a left side view of the example, and (c) a front view of another example. .

The needle tip portion 3 has a spherical tip 31 here. In other words, the tip 31 is spherical. Since the tip 31 of the needle tip portion 3 has a spherical surface, it is difficult for a hand to stick it.

The diameter of the tip 31 is smaller than the cross-sectional diameter of the proximal end of the needle tip portion 3, for example, 2/3 or less, more preferably 1/2 or less of the cross-sectional diameter of the proximal end.

As an example, as shown in FIGS. 5(a) and 5(b), the needle tip portion 3 has a shape in which the portion following the tip 31 gradually narrows toward the tip 31 as in FIG.

As an example, the portion of the needle tip portion 3 that continues to the tip 31 is also spherical, and when combined with the tip 31, it has a skewered dumpling shape. The portion of the needle tip portion 3 that continues to the tip 31 may be in the shape of a single sphere, or may be in the shape of a skewer with two or more spheres as shown in FIG. 5(c). Preferably, the diameter of the spherical or skewer-shaped portion following the tip 31 is the same as the spherical diameter of said tip 31 .

The needle tip portion 3 of this example can be manufactured by the steps shown in FIG. That is, the tip portion of the filament material processed into a sharp conical shape in the sharpening step S2 is modified into the above shape in the modifying step S7. For retouching, for example, a technique such as pressing using a mold or a jig or shaping by polishing is used. It should be noted that, as in the manufacturing method of FIG. 8, which will be described later, the needle tip portion forming step S8 may be processed into the above shape from the beginning.

<Modification 2 of Embodiment 1>
6A and 6B are diagrams showing an example of the needle tip portion of Modification 2 of Embodiment 1, and are (a) a front view and (b) a left side view.

Here, the tip 31 of the needle tip 3 has a curved surface, and the portion following the tip 31 is formed in a J shape. More specifically, the needle tip portion 3 is formed in a J-shape (""-shape") in which the portion continuing to the tip 31 is curved inward. By being formed in this manner, the needle tip portion 3 is less likely to be stuck by a hand. In addition, since the needle tip portion 3 can be formed thinner to the extent that safety is improved, it becomes easier for the needle to stick into fish or the like.

The needle tip portion 3 of this example can be manufactured by the steps shown in FIG. That is, the tip portion of the filament material processed into a sharp conical shape in the sharpening step S2 is modified into the above shape in the modifying step S7. Techniques such as polishing, bending, and pressing are used for the modification. It should be noted that, as in the manufacturing method of FIG. 8, which will be described later, the needle tip portion forming step S8 may be processed into the above shape from the beginning.

Although not shown, the needle tip portion 3 may be formed in the shape of soft cream or spiral.

<Embodiment 2>
7A and 7B are diagrams showing an example of the needle tip portion of Embodiment 2, in which (a) a front view and (b) a plan view of the tip are superimposed on an end view on the line AA. Although the illustrated needle tip portion 3 extends straight, it may be curved slightly inward as a whole as shown in FIG. 2 or the like, or may be curved slightly outward.

Here, as an example, the tip 31 of the needle tip portion 3 is formed to have a curved surface, more preferably a hemispherical surface as shown in the drawing. The portion of the needle tip portion 3 that continues to the tip 31 gradually narrows in the direction of the tip 31. As an example, as shown in FIG. The needle tip portion 3 has a circular cross section as shown in FIG. 7(b). The proximal end portion of the needle tip portion 3 may have a shape different from that of the portion continuing to the distal end 31 (portion near the distal end 31), for example, a cylindrical shape.

Since the tip 31 of the needle tip portion 3 has a hemispherical surface, it is difficult to stick the needle tip portion 3 with a hand. Also, since the portion continuing to the tip 31 is tapered, it is easy for fish and the like to stick it.

FIG. 8 is a flowchart showing another example of the method for manufacturing a fishing hook according to the present invention.

In this example, the end portion of the filament material cut to a predetermined length in the cutting step S1 is processed into the needle tip portion 3 shown in the drawing in the needle tip portion forming step S8.

The pointed end step S2 in FIG. 3 is mainly for sharpening the ends of the filament material, but the needle tip portion forming step S8 in this example is not limited to sharpening, and can be applied to a wider range of processes. , cutting, grinding, pressing, cutting, and other various methods are used to perform appropriate processing according to the shape of the needle tip portion 3 from the beginning. After the tip portion forming step S8, the timing forming step S3 to the post-processing step S6 are performed in the same manner as in the conventional art.

As a result, the fishing hook 1 can be optimally processed even if the hook tip portion 3 has a greater variety of shapes. Here, the filament material is not limited to one having a circular cross section, and may have a polygonal shape such as a triangle, a square, or a pentagon. Furthermore, various materials other than wire materials may be used.

<Modification 1 of Embodiment 2>
9A and 9B are diagrams showing an example of the needle tip portion of Modification Example 1 of Embodiment 2, in which (a) a front view and (b) a plan view of the tip are superimposed on the AA line end view.

Here, as shown in FIG. 9A, the tip 31 of the needle tip 3 is flat, and the portion following the tip 31 is a right-angled trapezoid with the oblique side on the inner side in front view. Note that the needle tip portion 3 may have a shape, such as a cylindrical shape, in which the portion closer to the proximal end is different from the portion continuing to the distal end 31 .

As shown in FIG. 9(b), the tip 31 may have a planar shape and a cross-sectional shape of a portion continuing from the tip 31 may be circular, or may be polygonal such as triangular, quadrangular, or hexagonal. good.

Since the tip 31 of the needle tip portion 3 of this example is flat, it is easier to process. In addition, the cross section can be formed in an appropriate shape such as circular or polygonal depending on the species of fish.

<Modification 2 of Embodiment 2>
10A and 10B are diagrams showing an example of the needle tip portion of Modification 2 of Embodiment 2, in which (a) a front view and (b) a plan view of the tip are superimposed on the AA line end view.

As shown in FIG. 10(a), the tip 31 of the needle tip portion 3 has a curved surface, and more preferably has a hemispherical surface as shown. The needle tip portion 3 has a shape in which a portion continuing to the tip 31 gradually narrows toward the tip 31, and as an example, as shown in the figure, it has an isosceles trapezoid in front view.

As an example, as shown in FIG. 10(b), the needle tip portion 3 has a circular cross section, and a portion continuing to the tip 31 has a truncated cone shape. The needle tip portion 3 may have a shape such that the portion near the base end is different from the portion continuing to the tip end 31, for example, a cylindrical shape.

As an example, although not shown, the needle tip portion 3 may have a polygonal cross section such as a triangle, a square, or a pentagon, and a portion continuing to the tip 31 may be a truncated pyramid. The needle tip portion 3 may have a shape different from that of the portion continuing to the tip 31, for example, a cylindrical shape.

Since the needle tip portion 3 of this example has a shape that is evenly cut from all four sides, it is easier to process.

<Modification 3 of Embodiment 2>
11A and 11B are diagrams showing an example of the needle tip portion of Modification 3 of Embodiment 2, in which (a) a front view and (b) a plan view of the tip are superimposed on the AA line end view.

Here, the needle tip portion 3 has a flat tip 31 as shown in FIG. 11(a). The needle tip portion 3 has a shape in which a portion continuing to the tip 31 gradually narrows toward the tip 31, and is, for example, an isosceles trapezoid when viewed from the front.

As an example, as shown in FIG. 11(b), the needle tip portion 3 has a circular cross-sectional shape and a truncated conical portion extending to the tip 31. As shown in FIG. The needle tip portion 3 may have a shape different from that of the portion continuing to the tip 31, for example, a cylindrical shape.

As an example, as shown in FIG. 11(b), the needle tip portion 3 has a polygonal cross-sectional shape such as a triangle, a square, or a hexagon, and the portion continuing to the tip 31 has a truncated pyramid shape. In this case as well, the proximal end portion of the needle tip portion 3 may have a different shape from the portion continuing to the distal end 31, such as a columnar shape.

Since the tip 31 of the needle tip portion 3 of this example is flat, it is easier to process. In addition, the cross section can be formed in an appropriate shape such as circular or polygonal depending on the species of fish.

<Modification 4 of Embodiment 2>
12A and 12B are diagrams showing an example of the needle tip portion of Modification 4 of Embodiment 2, in which (a) a front view, (b) a left side view, and (c) a plan view of the tip is superimposed on an AA line end view. is.

The tip 31 of the needle tip portion 3 here has a streak-like tip 31, and as an example, has a streak-like shape extending back and forth. The portion of the needle tip portion 3 that continues to the tip 31 is, for example, triangular when viewed from the front and rectangular when viewed from the left side, as shown in the drawing. The needle tip portion 3 may have a shape different from that of the portion continuing to the tip 31 at the portion closer to the proximal end, and may be, for example, a columnar shape.

In other words, the needle tip portion 3 has a shape in which the horizontal width gradually narrows as it goes forward, and finally becomes a streak (line). More specifically, the needle tip portion 3 is, for example, a cutting edge like the cutting edge of a kitchen knife, knife, or scissors.

Since the needle tip portion 3 having such a shape is shaped like a cutting edge, it can easily be stung by a fish or the like. On the other hand, it is hard to get stuck in the hand, and unless it is pulled or pushed along the line shape of the tip 31, it is hard to hurt.

Note that the tip 31 of the needle tip portion 3 may have a streak shape extending left and right, and the portion following the tip may be triangular when viewed from the left side and rectangular when viewed from the front.

The needle tip portion 3 of this example is processed into the needle tip portion 3 shown in the drawing in the needle tip portion forming step S8, and the tip 31 is processed to have a streaky shape. Since the tip portion 3 has a shape in which only both sides are cut, it is easier to process.

<Modification 5 of Embodiment 2>
13A and 13B are views showing an example of the needle tip portion of Modification 5 of Embodiment 2, and are (a) a front view of the example and (b) a front view of another example.

The tip 31 here has a curved surface, more preferably a hemispherical surface, and a portion continuing from the tip 31 has a uniform thickness, for example, a cylindrical shape.

As an example, as shown in FIG. 13(a), the needle tip portion 3 has a cylindrical shape as a whole except for the tip 31. As shown in FIG. Such a shape is suitable, for example, when the wire diameter of the wire material is small.

As an example, as shown in FIG. 13(b), the needle tip portion 3 has a truncated cone shape near the base end, and only the portion continuing to the tip end 31 has a cylindrical shape. Such a shape is suitable, for example, when the wire diameter of the wire material is large.

The needle tip portion 3 of this example is processed into the illustrated needle tip portion 3 in the needle tip portion forming step S8. Since the portion of the needle tip portion 3 that continues to the tip 31 has a uniform thickness, it is easier to process.

<Modification 6 of Embodiment 2>
14A and 14B are diagrams showing an example of the needle tip portion of Modification 6 of Embodiment 2, and are (a) a front view of the example, (b) a front view of another example, and (c) an end view on line AA.

The tip 3 of the needle tip 3 has a flat tip 31 and a uniform thickness in the portion following the tip 31 .

As an example, as shown in FIG. 14( a ), the needle tip portion 3 has a uniform thickness as a whole except for the tip 31 . The needle tip portion 3 may have a circular cross-sectional shape and an overall columnar shape, or may have a polygonal cross-sectional shape and an overall prismatic shape. Such a shape is suitable, for example, when the wire diameter of the wire material is small.

As an example, as shown in FIG. 14(b), the needle tip portion 3 has a tapered shape near the base end, and only the portion continuing to the tip 31 has a uniform thickness. In this case, when the cross section is circular, the portion closer to the proximal end has a truncated cone shape and the portion continuing to the distal end 31 has a cylindrical shape. When the cross section is polygonal, the portion closer to the base end has a truncated pyramid shape and the portion continuing to the tip 31 has a prism shape. Such a shape is suitable, for example, when the wire diameter of the wire material is large.

The needle tip portion 3 of this embodiment can be formed with a cross section of a circular shape, a polygonal shape, or the like, depending on the type of fish. Further, since the portion of the needle tip portion 3 continuing to the tip 31 has a uniform thickness and the tip is flat, processing is easier.

<Modification 7 of Embodiment 2>
15A and 15B are views showing an example of a needle tip portion according to Modification Example 7 of Embodiment 2, and are (a) a front view and (b) a left side view.

The probe tip 3 has two or more teeth 32 extending in the extending direction of the probe tip 3, and the tips 31 of the teeth 32 are curved, flat, or streaky. That is, here, the needle tip portion 3 is U-shaped or M-shaped. In other words, the needle tip portion 3 is divided into two or more forks like comb teeth along its extending direction (Y direction), each tooth portion 32 having a tip 31, and each tip 31 having a curved surface and a flat surface. or streaky.

Here, an example in which the tips 31 of the tooth portions 32 are hemispherical surfaces is illustrated, but the configurations of the above-described embodiments and modifications thereof can be appropriately applied to each tooth portion 32 .

Since the needle tip portion 3 of this example has two or more tooth portions 32, the needle tip portion 3 is easily stung by a fish or the like. In addition, since the tip 31 of each tooth 32 is curved, flat, or streaked, the user is less likely to be injured.
