Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view showing a simulated bait according to the present embodiment. FIG. 1 (a) shows the appearance when the artificial bait is at a shallow position, FIG. 1 (b) shows the appearance when the same artificial bait is at a medium depth position, and FIG. The situation when the same artificial bait is in a deep position is shown.

Hereinafter, the artificial bait (fishing tackle) 100 will be described.
As shown in FIG. 1A, the artificial bait 100 is provided so as to be movable between the water bottom 20 and the water surface 21, and the main body (the main body 1a in FIG. 1), the first ring 5, and the second A body portion 1 having a ring 6, a third ring 7 and a hook 8 and a weight 2 are provided. The artificial bait 100 is used by being connected to a fishing line 3 which is connected to a reel through a fishing rod (not shown).

  The main body portion 1 is a buoyant body having a main body (main body 1a in FIG. 1) that generates buoyancy. The main body portion 1 is formed of a material whose volume does not easily change due to water pressure, and is provided so that the specific gravity is smaller than the water quality of the water area to be used.

  The main body 1 is connected to the fishing line 3 by a first ring 5 which is an eyelet, is connected to the weight 2 by a second ring 6 which is an eyelet, and is connected to a fishing hook 8 by a third ring 7 which is an eyelet. ing. The first ring 5 is provided generally at the front of the main body 1, the second ring 6 is provided at the lower portion of the main body 1, and the third ring 7 is provided generally at the rear of the main body 1. There is.

  The main body portion 1 has a symmetrical shape when viewed from above or below (see FIG. 6A). Further, the main body portion 1 has a shape that does not dive or float beyond the preferable range when the fishing line 3 pulls the water at a suitable speed according to the use and the water area.

  Next, it is the weight 2 that adjusts the force to pull the main body 1 downward and the height of the main body 1 from the bottom of the water. The weight portion 2 is connected to the main body portion 1 so as to extend downward, and has a shape thinner than the main body portion 1 or thinner than the main body portion 1 at least when viewed from the front or the rear. Also, the weight 2 is provided so as to be bendable and has flexibility. The amount of weight (weight 2a in FIG. 1) hanging from the main body 1 in the water is negatively correlated with the amount of weight (weight 2a in FIG. 1) hanging from the main body 1 in the water. Adjusted by increasing or decreasing. For this reason, the more flexible the weight portion 2 is, or the more flexible the lower portion of the weight portion 2 is in the front-rear direction, the softer it can contact the water bottom 20 and land according to the undulation of the water bottom 20 Since the amount of the weight (the weight 2a in FIG. 1) can be increased or decreased more finely, the force with which the weight 2 pulls the main body 1 downward can be adjusted more finely.

  The weight portion 2 is formed of a material whose volume does not easily change due to water pressure, and is provided so that the specific gravity is larger than the water quality of the water area to be used. Further, the thinner the cross section perpendicular to the extending direction of the weight portion 2 or the thinner it looks at least from the front or rear, the less the resistance of water received when pulled by the fishing line 3. It is possible to suppress the rise.

  The weight 2 has a strength that does not break during use, and it is preferable to use a material that is as unobtrusive as possible in water and is as quiet as possible, but the fish collection effect by color, gloss, light reflection, or sound Or you may use the material which can expect a predatory impulse. In addition, when the weight 2 is rooted, only the weight 2 can be separated and separated, the second ring 6 connecting the main body 1 and the weight 2 to each other, or the middle of the weight 2 In this case, it is preferable to use a material that is harmless to the environment as the weight part 2 to be a waste weight.

  The height of the main body 1 from the bottom of the water was not only changed by the buoyancy of the main body 1 which does not change whether the water depth is shallow or deep depending on the application and water area, and the fishing line 3 pulled the water at a suitable speed The weight is adjusted in advance by selecting a suitable weight 2 in consideration of the latent power of the entire simulated bait 100 due to the shape of the main body 1 and the floating of the entire simulated bait 100 due to the resistance of water.

  FIG. 2 is a schematic view showing the artificial bait being pulled along the flat bottom of the water at a suitable speed. FIG. 2 (a) shows the simulated bait stopping in water, and FIG. 2 (b) shows the same simulated bait moving in the water.

  When the artificial bait 100 is stopped in water as shown in FIG. 2 (a), the gravity acting on the entire weight 2 is slightly larger than the buoyancy of the main body 1, as in FIG. In other words, the lower end of the weight 2b is adjusted in advance so as to come to rest in a state of being landed on the bottom 20 of the water.

  Further, as shown in FIG. 2 (b), the artificial bait 100 pulls the main body 1 downward and the main body 1 when the fishing line 3 pulls the water substantially horizontally at a suitable speed. The latent power of the entire simulated bait 100 according to the shape of 1 and the floating of the entire simulated bait 100 due to the buoyancy of the main body 1 and the resistance of water are in a state where the weight 2b is separated from the water bottom 20, ie It is pre-adjusted to balance in a state where gravity is working on the whole. As a result, the artificial bait 100 is moved along the flat bottom 20 at a certain range of height from the bottom while being separated from the bottom.

  FIG. 3 is a schematic view showing the artificial bait being pulled along the flat bottom of the water at a suitable speed. FIG. 3 (a) shows the simulated bait stopping in water, and FIG. 3 (b) shows the same simulated bait moving in the water.

  When the artificial bait 100 is stopped in water as shown in FIG. 3 (a), the gravity acting on the entire weight 2 is slightly smaller than the buoyancy of the main body 1 as in FIGS. 1 and 2. The lower end of the weight 2c is made to stand still in the state of being landed on the water bottom 20.

  On the other hand, as shown in FIG. 3 (b), the artificial bait 100 in FIG. 3 pulls the main body 1 downward when the fishing line 3 pulls the water substantially horizontally at a suitable speed. And the latent power of the entire simulated bait 100 due to the shape of the main body 1, and the floating of the entire simulated bait 100 due to the buoyancy of the main body 1 and the resistance of water are the amounts that were landed while stopped in water. In a state where a larger amount of weight 2c lands on the water bottom 20 than the lower end of the weight 2c, that is, the weight 2c is supported by the water bottom 20 so that the weight 2 lowers the main body 1 It is previously adjusted to balance in a state where the pulling force is reduced accordingly. As a result, the artificial bait 100 is moved along the flat bottom 20 at a certain range of height from the bottom, with a certain amount of weight 2 c being landed on the bottom 20.

  FIG. 4: is a schematic diagram which shows a mode that simulated bait climbs the level | step difference of the water bottom. Fig.4 (a) shows a state in which the artificial bait stops in water, FIG. 4 (b) shows a state in which the same artificial bait moves in the water, and FIG. 4 (c) shows a step by the same artificial bait FIG. 4 (d) shows the same artificial bait as it has just risen the step.

  As shown in FIG. 4A, when the artificial bait 100 is stopped in water, the weight 2 pulls the main body 1 downward, and the buoyancy of the main body 1 has a certain amount of The weight 2 d is adjusted in advance so as to be balanced in a state where the weight 2 d is landed on the water bottom 20.

  In addition, as shown in FIG. 4 (b), the artificial bait 100 pulls the main body 1 downward and the main body 1 when the fishing line 3 pulls the water substantially horizontally at a suitable speed. Stop in the water with the weight 2d away from the bottom of the water until the latent power of the entire simulated bait 100 according to the shape of 1 and the floating of the entire simulated bait 100 due to the buoyancy of the main body 1 and the water resistance are balanced. A smaller amount of weight 2 d is moved in a state of being landed on the water bottom 20 than the amount of weight 2 d which has sometimes been landed.

  Next, as shown in FIG. 4C, when the artificial bait 100 starts to ascend the step 20a, a larger amount of weight 2d is converted to the topography of the step 20a than when moving on a flat bottom. Come to land along. At this time, since a larger amount of weight 2d is supported by the step 20a, the force by which the weight 2 pulls the main body 1 downward decreases accordingly, and the main body 1 rises along the topography of the step 20a. Then, after rising the step 20a, as shown in FIG. 4 (d), the artificial bait 100 moves on the water bottom 20 in a landing state substantially the same as the state shown in FIG. 4 (b).

  FIG. 5: is a schematic diagram which shows a mode that simulated bait descends the level difference of the bottom of the water. Fig.5 (a) shows the mode before the same artificial bait as FIG. 4 descend | falls a level | step difference, FIG.5 (b) shows the mode immediately after the same artificial bait as FIG. 4 descend | falls a level | step difference, FIG.5 (c) 4 shows the same artificial bait as in FIG. 4 immediately before landing on the bottom of the water, and FIG. 5 (d) shows the same artificial bait as in FIG. 4 landing on the bottom of the water after landing on the step.

  The artificial bait 100, as shown in FIG. 5 (a), pulls the water approximately horizontally at a suitable speed by the fishing line 3, and reaches a certain amount of weight 2d on the bottom 20 until it reaches the step 20b. I am moving with landing.

  Next, as shown in FIG. 5B, when the artificial bait 100 starts to descend the step 20b, the weight 2d that has been landed on the water bottom 20 is released from the water bottom 20. At this time, the force by which the weight 2 pulls the main body 1 downward is increased by that amount, and the force by which the weight 2 pulls the main body 1 downward and the latent power of the entire artificial bait 100 due to the shape of the main body 1 It becomes larger than the floating of the artificial bait 100 whole by the buoyancy and the resistance of water. For this reason, as shown in FIG. 5C, the artificial bait 100 descends along the topography of the step 20b.

  The lowered artificial bait 100 causes the weight 2d to land on the bottom 20 again, as shown in FIG. 5 (d). At this time, the force by which the weight 2 pulls the main body 1 downward decreases, and the force by which the weight 2 pulls the main body 1 downward and the latent power of the entire artificial bait 100 due to the shape of the main body 1 The bottom 20 is moved with the floating force of 1 and the floating of the whole of the artificial bait 100 due to the resistance of water balanced, that is, substantially the same landing condition as the condition shown in FIG. 5 (a).

  The artificial bait 100 according to the present embodiment has a main body 1 having main bodies 1a, 1b, 1c and 1d which are buoyant bodies, and weights 2a, 2b, 2c and 2d, and can be bent downward from the main body 1 It comprises a weight portion 2 for adjusting the pulling force of the main body portion 1 downward according to the amount of extension and landing on the water bottom 20. Thus, the main body 1 can be maintained at a certain range of height from the water bottom 20 regardless of the water depth, and the weight 2 adjusts the pulling force of the main body 1 downward according to the unevenness of the water bottom 20 it can. In addition, it can stand in water, and because weight 2 is lighter and thinner than before, it has good stability and operability, and it is hard to get caught in an obstacle, and it does not hit or scratch water bottom 20 Because of this, it is possible not to adversely affect fishing results and fishing taste.

  As mentioned above, although the present invention was explained based on one embodiment, the present invention is not limited to this. Although the present invention is described using the artificial bait 100 as a fishing tackle in the above embodiment, the present invention is not limited to this. For example, as shown in FIGS. 6 (b) and 6 (c), an underwater mobile An underwater video camera may be mounted on the main body 1 as the 200 and the underwater moving body 300.

  Moreover, in the said embodiment, as shown to Fig.6 (a), although the shape of the main-body part 1 was formed in left-right symmetry seeing from upper or lower direction, this invention is not limited to this. For example, as shown in FIGS. 6 (b) and 6 (c), it may be formed as the underwater moving body 200 and the water moving body 300 having an asymmetric shape when viewed from above or below. Thus, the underwater moving body 200 and the underwater moving body 300 can move underwater while being deflected to the right or left in the direction in which the rope 10 is pulled.

  Furthermore, in the above embodiment, when the artificial bait 100 is stopped in water, the lower end of the weight 2 or a certain amount of weight 2 is adjusted in advance so that it lands on the water bottom 20. The invention is not limited to this. For example, as shown in FIG. 7A, when the artificial bait 100 is stopped in water, the so-called suspended state, that is, the gravity acting on the entire weight 2 becomes equal to the buoyancy of the main body 1 That is, as the whole artificial bait 100, it may be adjusted in advance so that the water quality and the specific gravity of the water area to be used become equal. At this time, the artificial bait 100 hardly lands on the water bottom 20 and becomes difficult to float up to the water surface 21. And as the simulated bait 100 is shown in FIG.7 (b), when the weight 2g lands on the lump 20c, the power which the weight part 2 pulls down the main-body part 1 reduces by that much, and the topography of the lump 20c It is supposed to rise along the

  Furthermore, although the said embodiment provided the weight part 2 which has the weight 2a, 2b, 2c, 2d, 2e, 2f, 2g which is threadlike weight, this invention is not limited to this. For example, as shown in FIG. 8 (a), the weight 2 may be provided with a plurality of fish collecting plates 11 or as shown in FIG. 8 (b), a weight 2 having weights 2x which are a plurality of ball shaped weights. In place of the hooks 8 to connect the second fishing line 4 to the third ring 7 or, as shown in FIG. 8 (c), a weight section 2 having a weight 2y which is a chain weight. And the third ring 7 may be eliminated.

  Moreover, in the said embodiment, although the fishhook 8 was directly connected with the 3rd ring 7, this invention is not limited to this. For example, as shown in FIG. 9, instead of the hooks 8, a second fishing line 4 may be connected, and the hooks 8 may be connected to hook the live bait 9 via the second fishing line 4. Further, as shown in FIG. 10, while holding the fishing line 3 in the middle via the line release 17 connected to the third ring 7 of the main body 1, the lure 12 is connected to the tip of the fishing line 3. A downrigger cable 16 is connected to the first ring 5, and the fishing line 3 is pulled by a fishing rod 14 provided on the ship 13, and the downrigger 15 may be pulled by a cable 16 to form a fishing tackle 500.

  Furthermore, in the said embodiment, although the underwater moving body and the fishing tackle were used in stop water, this invention is not limited to this. For example, as shown in FIG. 11, it may be used in water areas where there are rivers and tidal currents, that is, flowing water.

  The present invention can be applied to any type of underwater vehicle or fishing tackle as long as the operation and effects of the present invention can be achieved.
