EMBODIMENTS FOR CARRYING OUT THE INVENTION

A hunting and fishing gear illustrated in FIG. 1 includes a haft 1, a harpoon body 2, and a plurality of harpoon tips 3. The haft 1 is a platy member in which a longitudinal direction X exists in a direction from one end portion to the other end portion of the haft 1. The harpoon body 2 is a platy member extending in the longitudinal direction X of the haft 1 from one end portion of the haft 1, in which the longitudinal direction X exists in a direction from one end portion to the other end portion of the harpoon body 2. The plurality of harpoon tips 3 are platy members protruding in a lateral direction Y from one side portion of the harpoon body 2 in a direction intersecting the longitudinal direction X. Each of the harpoon tips 3 is located on one imaginary line 8 parallel to the longitudinal direction X of the harpoon body 2. The hunting and fishing gear is used by holding a handle 7 with a person's hand 17 to swing it down in a direction of an arrow Z, thus it is easier to handle compared to a conventional harpoon which is used to pierce in the longitudinal direction of the haft, and also the harpoon tips are hard to be damaged.

The number of the harpoon tips 3 is not limited to six, however, in the exemplified aspect, the number of the harpoon tips 3 is six, a first space part 4 and a second space part 6 are provided as space parts, and the first space part 4 and the second portion 6 are alternately adjacent to each other in the longitudinal direction X of the harpoon body 2.

The hunting and fishing gear may have a shape in which a barb 5 is not provided in the first space part 4. Even in this case, it is possible to pierce a prey with the plurality of harpoon tips 3 by utilizing the centrifugal force generated when a person grips a handle 7 of the hunting and fishing gear with a person's hand 17 and swings it down in a direction of the arrow Z. Further, the barb 5 may be provided in a shape protruding from at least one of the harpoon tips 3 in the first space part 4 toward the first space part 4 side. However, in the exemplified aspect, the barbs 5 are provided in the shape protruding toward the first space part 4 side from a pair of harpoon tips 3 in the first space part 4. It is to be noted that, in the case where the barbs 5 are provided on the pair of harpoon tips 3 in the first space part 4, it becomes difficult for the prey to escape and thus the prey is easily captured, compared to the case where the barbs 5 are provided on at least one of the harpoon tips 3 in the first space part 4. In the exemplified aspect, the barbs and come-off prevention sections are not provided in the second space part 6.

As described above, the hunting and fishing gear illustrated in FIG. 1 is configured to include the haft 1, the harpoon body 2 extending in the longitudinal direction X of the haft 1 from on end portion of the haft 1, the plurality of harpoon tips 3 protruding in the lateral direction Y from one end portion in the direction intersecting the longitudinal direction X of the harpoon body 2, and the barb 5 provided so as to protrude into the first space part 4 from at least one of the harpoon tips 3 in the first space part 4. Accordingly, it is possible to make the hunting and fishing gear from a metal plate such as an iron plate or a stainless steel plate by press processing. In addition, a handle 7 indicated by an imaginary line may be externally attached to the haft 1 of the hunting and fishing gear made of a metal plate such as an iron plate or a stainless steel plate by the press processing so that it can be easily gripped by hand. Incidentally, the hunting and fishing gear may be made by cutting out from a metal plate by laser processing, or by casting, however, it is easier to make the hunting and fishing gear by the press processing or laser processing than by casting.

Also, an attachment structure of the handle 7 may be provided on the haft 1 so that the handle 7 can be attached and detached. A rod may be attached to the haft 1 to make the hunting and fishing gear to be a spear or a scythe.

As illustrated in FIG. 2, blades 9 are formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4. That is, the plate members of the pair of harpoon tips 3 and the barbs 5 in the first space part 4 are grinded so that the plate thicknesses thereof become gradually thinner toward the pair of harpoon tips 3 side and the barb 5 side. By being grinded in this way, the blades 9 are formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4. In other words, the blades 9 are provided on the pair of harpoon tips 3 so as to face with each other in the first space part 4. Since the blades 9 are formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4 in this way, the hunting and fishing gear achieves an advantageous effect that the pair of harpoon tips 3 and the barbs 5 in the first space part 4 easily pierce the prey.

Further, no blades are formed on the pair of harpoon tips 3 in the second space part 6, and also no blades are formed on the harpoon body 2 in the second space part 6 and on the harpoon body 2 in the first space part 4. That is, the pair of harpoon tips 3 in the second space part 6 are kept intact in terms of the plate thickness thereof and are not formed to be the blades. Because the pair of harpoon tips 3 in the second space part 6 are not provided with blades in a manner as to face with each other, there is an advantageous effect that the prey pierced by the harpoon tips 3 is difficult to come off and even if the prey struggles, it is difficult for the prey to escape.

Moreover, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4 are kept intact in terms of the plate thickness thereof and are not formed to be the blades. As such, because the pair of harpoon tips 3 in the second space part 6, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4 are not provided with the blades, it is possible to prevent the prey from being cut by the portions that are not provided with the blades.

Incidentally, the hunting and fishing gear may be configured such that the blades 9 are not formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, on the other hand, blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. Even in such a case, similar advantageous effects as those described in the paragraphs immediately above are achieved.

In the meantime, the hunting and fishing gear may be configured such that the blades 9 are formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, and blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. In this case, there is an advantageous effect that the harpoon tips 3 easily pierce the prey and the prey is easily removed from the harpoon tips 3. However, when the prey pierced by the harpoon tips 3 struggles, the blades 9 and the blades similar to the blade 9 of the harpoon tips 3 cut out the pierced portion of the prey, hence it becomes easy for the prey to escape.

In a hunting and fishing gear illustrated in FIG. 3, since the forefront harpoon tip 3 protrudes in the lateral direction over the other harpoon tips 3 positioned on one imaginary line 8, the forefront harpoon tip 3 can protect the other tips 3 from hitting rocks or the ground to thereby protect the other tips 3 from being damaged. In a case where the forefront harpoon tip 3 hits rocks or the ground and the sharpness thereof is deteriorated, it is sufficient to grind only the forefront harpoon tip 3. In the meantime, although a blade 13 does not need to be provided on the back side of the harpoon body 2, FIG. 3 exemplifies a case where the blade 13 is provided. A harpoon tip side protection section 15 and a back side protection section 16 are provided at an distal end portion 14 of the harpoon body 2. The harpoon tip side protection section 15 is provided as an inclined portion inclining from the harpoon tip 3 toward the distal end of the hunting and fishing gear so as to ease an impact even if the harpoon tip 3 hits the ground when the harpoon tip 3 side of the hunting and fishing gear is swung down. The back side protection section 16 is provided as an inclined portion inclining from the blade 13 toward the distal end of the hunting and fishing gear so as to ease the impact even if the blade 13 hits the ground when the back side of harpoon body 2 of the hunting and fishing gear is swung down.

In addition, as illustrated in FIG. 4, if the tip of the forefront harpoon tip 3 is provided to face the handle 7 side and the forefront harpoon tip 3 is protruded in the lateral direction over the other harpoon tips 3, when the hunting and fishing gear is put back into a sheath, the harpoon tips 3 are not caught and the storage becomes easy. Furthermore, since the tip of the forefront harpoon tip 3 is provided so as to face the handle 7 side, it is possible to move the captured prey by hooking it on the tip of the hunting and fishing gear.

The blade 9 illustrated in FIG. 2 may be provided in the hunting and fishing gears illustrated in FIGS. 3 and 4. In such a case, there is an advantageous effect that the pair of tips 3 and the barbs 5 in the first space part 4 easily pierce the prey. Further, since the pair of harpoon tips 3 in the second space part 6 are not provided with blades in a manner as to face with each other, there is an advantageous effect that it is difficult for the prey pierced by the harpoon tips 3 to come off and even if the prey struggles, it is difficult for the prey to escape. Furthermore, since no blades are formed on the pair of harpoon tips 3 in the second space part 6, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4, it is possible to prevent the prey from being cut by the portions that are not provided with the blades.

Incidentally, the hunting and fishing gear may be configured such that the blades 9 are not formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, on the other hand, blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. Even in such a case, a similar advantageous effect as that described in the paragraph immediately above is achieved.

Further, the hunting and fishing gear may be configured such that the blades 9 are formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, and blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. In this case, there is an advantageous effect that the harpoon tips 3 easily pierce the prey and the prey is easily removed from the harpoon tip 3. However, when the prey pierced by the harpoon tips 3 struggles, the blades 9 and the blades similar to the blade 9 of the harpoon tips 3 cut out the pierced portion of the prey, hence it becomes easy for the prey to escape.

In the hunting and fishing gear illustrated in FIG. 5, the forefront portion protruding in the lateral direction over the other harpoon tips 3 is made to be a protection section 10 as a protrusion not being the harpoon tip 3 and not being provided with the barb. Therefore, the protection section 10 can protect the other harpoon tips 3 from hitting rocks or the ground to thereby protect the other tips 3 from being damaged. Further, when the hunting and fishing gear is put back into the sheath, the harpoon tips 3 are not caught hence the storage becomes easy.

The blade 9 illustrated in FIG. 2 may be provided in the hunting and fishing gear illustrated in FIG. 5. In such a case, there is an advantageous effect that the pair of harpoon tips 3 and the barbs 5 in the first space part 4 easily pierce the prey. Further, since the pair of harpoon tips 3 in the second space part 6 are not provided with blades in a manner as to face with each other, there is an advantageous effect that it is difficult for the prey pierced by the harpoon tips 3 to come off and even if the prey struggles, it is difficult for the prey to escape. Furthermore, since no blades are formed on the pair of harpoon tips 3 in the second space part 6, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4, it is possible to prevent the prey from being cut by the portions that are not provided with the blades.

Incidentally, the hunting and fishing gear may be configured such that the blades 9 are not formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, on the other hand, blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. Even in such a case, a similar advantageous effect as that described in the paragraphs immediately above is achieved.

Further, the hunting and fishing gear may be configured such that the blades 9 are formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, and blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. In this case, there is an advantageous effect that the harpoon tips 3 easily pierce the prey and the prey is easily removed from the harpoon tips 3. However, when the prey pierced by the harpoon tips 3 struggles, the blades 9 and the blades similar to the blade 9 of the harpoon tips 3 cut out the pierced portion of the prey, hence it becomes easy for the prey to escape.

In a hunting and fishing gear illustrated in FIG. 6, in the first space part 4 as a side where the pair of harpoon tips 3 among the three or more harpoon tips 3 face with each other, come-off prevention sections 11 are provided in the convex and concave shape from the mutually facing pair of harpoon tips 3 toward the first space part 4 side. The come-off prevention portion 11 illustrated in FIG. 6 corresponds to the barb 5 illustrated in FIGS. 1 to 4, and has the convex and concave shape so that the harpoon tips 3 do not come out of the prey pierced by the harpoon tips 3. FIG. 6 exemplifies an aspect in which the blades 9 are provided on the harpoon tips 3 positioned ahead of the come-off prevention sections 11. In such a case, there is an advantageous effect that the pair of harpoon tips 3 in the first space part 4 easily pierce the prey.

Further, no blades are formed on the pair of harpoon tips 3 in the second space part 6, and also no blades are formed on the harpoon body 2 in the second space part 6 and on the harpoon body 2 in the first space part 4. That is, the pair of harpoon tips 3 in the second space part 6 are kept intact in terms of the plate thickness thereof and are not formed to be the blades. Because the pair of harpoon tips 3 in the second space part 6 are not provided with blades in a manner as to face with each other, there is an advantageous effect that the prey pierced by the harpoon tips 3 is difficult to come off and even if the prey struggles, it is difficult for the prey to escape.

Moreover, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4 are kept intact in terms of the plate thickness thereof and are not formed to be the blades. As such, because the pair of harpoon tips 3 in the second space part 6, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4 are not formed to be the blades, it is possible to prevent the prey from being cut by the portions that are not formed to be the blades.

Incidentally, the hunting and fishing gear may be configured such that the blades 9 are not formed on the pair of harpoon tips 3 positioned ahead of the come-off prevention sections 11, on the other hand, blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. Even in such a case, similar advantageous effects as those described in the paragraphs immediately above are achieved.

Further, the hunting and fishing gear may be configured such that the blades 9 are formed on the pair of harpoon tips 3 positioned ahead of the come-off prevention sections 11, and blades similar to the blade 9 are formed on the pair of harpoon tips 3 in the second space part 6. In this case, there is an advantageous effect that the harpoon tips 3 easily pierce the prey and the prey is easily removed from the harpoon tips 3. However, when the prey pierced by the harpoon tips 3 struggles, the blades 9 and the blades similar to the blade 9 of the harpoon tips 3 cut out the pierced portion of the prey, hence it becomes easy for the prey to escape.

Also in the hunting and fishing gear illustrated in FIG. 6, the forefront harpoon tip 3 illustrated in FIG. 3 or the protection section 10 illustrated in FIG. 5 may be provided.

In a hunting and fishing gear illustrated in FIG. 7, in the first space part 4 as a side where the pair of harpoon tips 3 among the three or more harpoon tips 3 face with each other, barbs 5 are provided in the shape protruding from the mutually facing pair of harpoon tips 3 toward the first space part 4 side. The come-off prevention sections 12 are provided in the second space part 6 adjacent to the first space part 4, in the shape of convex and concave from mutually facing pair of harpoon tips 3 toward the second space part 6 side. FIG. 7 illustrates a case where the blades 9 are formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4. In such a case, there is an advantageous effect that the pair of harpoon tips 3 and the barbs 5 in the first space part 4 easily pierce the prey.

Furthermore, no blades are formed on the pair of harpoon tips 3 in the second space part 6, and also no blades are formed on the harpoon body 2 in the second space part 6 and on the harpoon body 2 in the first space part 4. That is, the pair of harpoon tips 3 in the second space part 6 are kept intact in terms of the plate thickness thereof and are not formed to be the blades. Because the pair of harpoon tips 3 in the second space part 6 are not provided with blades in a manner as to face with each other, there is an advantageous effect that the prey pierced by the harpoon tips 3 is difficult to come off and even if the prey struggles, it is difficult for the prey to escape.

Moreover, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4 are kept intact in terms of the plate thickness thereof and are not formed to be the blades. As such, because the pair of harpoon tips 3 in the second space part 6, the harpoon body 2 in the second space part 6 and the harpoon body 2 in the first space part 4 are not provided with blades, it is possible to prevent the prey from being cut by the portions that are not provided with the blades.

Incidentally, in FIG. 7, the blades 9 may not be formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, on the other hand, blades similar to the blade 9 may be formed on the harpoon tips 3 positioned ahead of the come-off prevention sections 12. Even in such a case, similar advantageous effects as those described in the paragraphs immediately above are achieved.

Further, the blades 9 may be formed on the pair of harpoon tips 3 and the barbs 5 in the first space part 4, and blades similar to the blade 9 may be formed on the harpoon tips 3 positioned ahead of the pair of come-off prevention sections 12 in the second space part 6. In this case, there is an advantageous effect that the harpoon tips 3 easily pierce the prey and the prey is easily removed from the harpoon tips 3. However, when the prey pierced by the harpoon tips 3 struggles, the blades 9 and the blades similar to the blade 9 of the harpoon tips 3 cut out the pierced portion of the prey, hence it becomes easy for the prey to escape.

Also in the hunting and fishing gear illustrated in FIG. 7, the forefront harpoon tip 3, the blade 13, the harpoon tip side protection section 15 and the back side protection section 16 illustrated in FIG. 3 or the protection section 10 illustrated in FIG. 5 may be provided.
