Description

  The present invention relates to a weight used for fishing, and more particularly to a fishing weight useful for fishing in places where there are many obstacles such as rocks and reefs on the bottom of water.

  When fishing in rivers, lakes, or the sea, where there are many obstacles such as rocks or reefs on the bottom of the water, these obstacles can easily catch weights, and it is not possible to collect weights. It takes a lot of time to get rid of the obstacles. Conventionally, inventions for solving this type of problem have been proposed. For example, Patent Document 1 discloses a weight in which a mechanism for preventing rooting consisting of a star-shaped protrusion is arranged on the frontal portion of the weight, and the weight is likely to be caught on an obstacle such as a rock or a reef. Then, the head of the weight is pulled away from the rocks and reefs by the device placed on the front of the weight.

  On the other hand, the weight described in Patent Document 2 is a weight body such as a sphere shape, a cone shape, or a spindle shape made of a relatively hard metal material or alloy instead of a conventional lead weight. The structure is provided with a cylindrical protective tube made of a soft member fixed in a thread insertion hole provided in the weight body, and the weight is not deformed or scraped even when it comes into contact with rocks. .

  However, the weight described in Patent Document 1 is troublesome because a mechanism for preventing rooting is provided separately from the weight, and a star-shaped protrusion is formed in the gap between the rock and the rock. There was a risk of getting caught. On the other hand, since the weight body described in Patent Document 2 has a bulge in the shape of the weight body, if the weight body falls into a gap such as a rock, the bulge of the weight body is caught in a rock corner or the like and the gap Could not be pulled from.

  Therefore, the problem to be solved by the present invention is to make it difficult to catch weights on obstacles such as rocks and reefs when fishing in lakes and seas, and to easily collect even if they are caught. It is to provide a fishing weight that can be used.

  In order to solve the above-described problems, a fishing weight according to the present invention is composed of an elongated rod-like body having tapered tip portions at both ends, and through holes are provided at the tip portions at both ends.

  In the fishing weight according to the present invention, it is desirable that the rod-shaped body is a hard metal such as stainless steel, iron, or an iron alloy. Moreover, it is desirable that the surface of the rod-like body has a smoothness equal to or higher than the finished surface obtained by cutting.

Moreover, the fishing weight which concerns on this invention consists of a several rod-shaped piece by which the said rod-shaped body was divided | segmented into the single member or two or more. When divided, the plurality of rod-like pieces are detachably connected to form a single elongated rod-like body.
The rod-like body of the present invention includes not only a cylindrical body but also a polygonal column such as a hexagonal column and an octagonal column.

  Since the fishing weight according to the present invention is composed of an elongated rod-like body having tapered tip portions at both ends, the weight is difficult to be caught by obstacles such as rocks and reefs, and it is also difficult to enter a gap between accumulated obstacles. In addition, even if the weight gets caught in an obstacle such as rock or reef, or falls into a gap such as accumulated rock, the tip is tapered, so once the tip enters the gap, Can slip through the gap. Moreover, since the through-hole is provided in the front-end | tip part of the both ends of a rod-shaped body, a road thread and Harris can be easily connected to this through-hole.

It is a front view which shows the weight for fishing which concerns on 1st Example of this invention. It is a perspective view when a fishing weight is set on a fishing rod. It is explanatory drawing which shows the state by which the weight for fishing was drawn in the clearance gap between the rocks of a water bottom. It is explanatory drawing at the time of pulling out the weight for fishing from the crevice between the rocks of the bottom of the water. It is explanatory drawing which shows the state by which the weight for fishing was pulled out from the clearance gap between the rocks of a water bottom. It is a perspective view which shows the weight for fishing which concerns on 2nd Example of this invention. It is a partial front view which shows one modification of the front-end | tip part of a fishing weight. It is a partial front view which shows the other modification of the front-end | tip part of a fishing weight.

Hereinafter, embodiments of a fishing weight according to the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 shows a fishing weight according to a first embodiment of the present invention. The fishing weight 1 is composed of an elongated cylindrical body 2 having conical tip portions 3a, 3b at both ends, and the cylindrical body 2 is composed of a hard metal having a predetermined smoothness on the surface. The overall length of the cylindrical body 2 is not particularly limited, but is preferably about 10 to 20 cm. If it is too short, sufficient weight and function as a weight cannot be secured, and if it is too long, it is inconvenient to handle. The diameter of the cylindrical body 2 is preferably about 6 to 10 mm. This is because if the ratio of the diameter to the length is too large, it becomes difficult for the tip portion to pass through the gap between the rocks. Each tip 3a, 3b has a tapered conical shape, and the apex angle α of this conical shape is preferably about 20 to 45 degrees. This is because it is easy to pull out the weight when it falls into the gap between the rocks. Moreover, each front-end | tip part 13a, 13b of the front-end | tip part 3a, 3b becomes a rounded shape, and makes resistance small when it hits a rock angle.

  The fishing weight 1 of the present invention is preferably made of hard metal. This is to prevent deformation when collecting the weight caught on the obstacle. It is desirable that the cylindrical body 2 has such a hardness that it does not deform when it hits a rock corner or receives pressure from a rock. For example, a Vickers hardness of HV120 or higher is desirable. The material is not particularly limited as long as a certain level of hardness is ensured, but stainless steel, iron, an alloy of iron, and the like are suitable from the viewpoint of durability, cost, specific gravity, and the like.

  It is desirable that the surface of the fishing weight 1 of the present invention has a predetermined smoothness. This is because when the weight slips through the gap between the rocks and hits the rock, the contact resistance of the surface of the cylindrical body 2 is reduced to facilitate slipping. The predetermined smoothness is preferably equal to or higher than the finished surface when the metal surface is cut, for example, but does not require a mirror finish. When the predetermined smoothness is represented by a numerical value, it is preferably approximately 25-S (JIS B 0659) or less.

  The fishing weight 1 of the present invention is provided with circular through holes 4 a and 4 b at the tip portions 3 a and 3 b at both ends of the cylindrical body 2. When used, it does not matter whether the cylindrical body 2 is up or down. However, when it is set on the fishing rod 5 as shown in FIG. 2, for example, one tip 3a is set as the upper side of the weight, and the fishing rod 5 is inserted into the through hole 4a. One end of the thread 6 extending from the tip is connected to a ring 7a and a connecting tool such as a twist 7b. In addition, one end of Harris 8 is connected to the through hole 4b of the other tip portion 3b on the lower side of the weight via a connecting tool such as a ring 9a and a twist 9b. In addition, you may connect the thread 6 directly through the through-hole 4a, without passing through the said connector.

  Next, the operation of the fishing weight 1 having the above configuration will be described with reference to FIGS. Here, a case where fishing weight 1 of the present invention is drawn together with the scorpion 12 into the gap 11 such as the rock 10 deposited on the bottom of the water will be described as an example when root fish such as scorpion is fishing in the sea. Especially in places where rocks 10 are deposited, a lot of spaces and gaps 11 are formed between the rocks, so the scorpions 12 tend to gather, but the weights are also easily caught, and the weights fall into the spaces and the gaps 11. easy.

  However, in the fishing weight 1 of the present invention, as shown in FIG. 4A, even if the fishing weight 1 falls into the gap 11 of the rock 10, the tip 3a on the upper side of the cylindrical body 2 has a conical shape. It penetrates into the gap 11 of the rock 10 while being guided by the inclined surface. Then, as the tip 3a enters the gap 11, as shown in FIG. 4 (b), the cylindrical part 2 is guided to the gap 11 of the rock 10, and the rock 10 is straight without being deformed. It can slip through the gap 11 and, as shown in FIG. 5, the scorpion 12 can be picked up together with the collection of the fishing weight 1. Since the tip 3a on the upper side of the cylindrical body 2 has a conical tapered shape, the tip easily enters the gap 11 of the rock 10, and once the tip enters, the conical inclined surface of the tip 3a. The cylindrical body 2 penetrates into the gap 11 by being guided by, and then the gap 11 can be smoothly slipped through. Furthermore, since the surface of the cylindrical body 2 has a predetermined smoothness, even the rough and rough rock surface of the rock 10 can pass through smoothly.

  FIG. 6 shows a second embodiment of a fishing weight according to the present invention. The fishing weight 21 has the same configuration as the fishing weight according to the first embodiment, except that one cylindrical body 22 is constituted by the cylindrical pieces 22a and 22b divided into two. Detailed description is omitted by assigning the same reference numerals to the same components.

  In this embodiment, the two columnar pieces 22a and 22b are detachably connected to form one columnar body 22. As shown in FIG. 6, the connecting means is formed on one columnar piece 22a. And the male screw portion 24 formed on the other cylindrical piece 22b and screwed into the female screw portion 23. Of course, connection means other than screwing may be used. Moreover, although this embodiment demonstrated the case where the cylindrical body 22 was divided into 2 parts, it is also possible to make it into 3 or more divisions according to the length of the cylindrical body 22. FIG. Thus, by dividing the cylindrical body 22, handling during storage is facilitated and convenience can be enhanced.

  In all of the above-described embodiments, the rod-like body of the fishing weight is described as an example of a cylinder. However, the rod-like body of the present invention includes a polygonal column such as a hexagonal column or an octagonal column. . The shape of the tip portion also corresponds to the cross-sectional shape of the rod-shaped body so that it is a hexagonal pyramid when the rod-shaped body is a hexagonal column, and an octagonal pyramid when the rod-shaped body is an octagonal column.

  Further, the tapered shape of the distal end portions 3a and 3b is not limited to the cone shape such as the cone shape or the pyramid shape as described above, and as shown in FIG. 7, the tapered shape has a slight bulge toward the distal end. As shown in FIG. 8, the tip portions 3c and 3d may be formed as tip portions 3e and 3f that are slightly curved and taper toward the tip.
