Description

  The present invention relates to a method for manufacturing a threaded float having a threading hole penetrating the floating body in the vertical direction, and more particularly to a method for manufacturing a threaded float corresponding to an evolved behavioral habit of preventing fish from being caught.

  Fish have evolved behavioral habits that prevent them from being caught. Specifically, they dislike the weight of the device, dislike the resistance given by the refraction and curvature of the device, and the posture when the floating float is drawn into the water. Has the habit of hating resistance given by change. Therefore, in order to catch fish with these improved behavioral habits, there is a need for a floating float that can cope with the evolved behavioral habits.

  In order to respond to the fish's advanced behavioral habits, when the device reaches a certain depth after the device is turned on, the fish hook will be slanted in the direction that the device will flow, and the fish hook will be slanted. Moreover, it is necessary to realize the immobilization of the floating stopper that can be caught clearly, and to smoothly sink the fishing line into the water even with a light mechanism.

In Patent Document 1, a metal thread is used as a material, a thread insertion hole is formed so that the inner diameter changes along the direction in which the thread is inserted, and an outer diameter corresponding to the upper through hole is provided. A metal pipe provided through the through hole of the main body and a lower end of the metal pipe provided to be fitted into the opening of the lower through hole, and are formed separately from or integrally with the metal pipe. There is described a through-bore which is provided with a metal member composed of a metal end metal part and is fixed in a state in which the joint surface between the metal member and the metal main body is sealed with an adhesive.
Further, Patent Document 2 describes a structure of a through floating according to the inventor's invention.

JP 2012-196185 A Japanese Patent No. 583271

  Although what was described in patent document 1 is that a core material is formed with a metal pipe, if the joint surface of a metal pipe and a main body is joined with an adhesive agent, a metal pipe, a main body, and The adhesive is inserted into the slight gap. Then, it is difficult to fill the entire space in the gap between the metal pipe and the main body, and an air layer that is not filled with the adhesive is formed in this space.

  In order to obtain proper buoyancy and balance in the water, the uniformity of the material in the inside float is extremely important. However, when such an air layer is formed, the inside float is Moisture that has entered inside accumulates in this air layer, which is a major factor that impairs the uniformity of the material inside the floating inside.

  When such a situation occurs, it is not possible to realize an ideal type of mechanism in which the angle from the hook to the floating hole is inclined, and the posture change of the floating hole that is given when the fish pulls it into the water together with the floating hole Can not provide a floating float corresponding to the evolution of fish that does not give changing resistance.

  The present invention has been made in order to solve such problems, and suppresses the floating of the floating through the slanting line of the through floating while ensuring the uniformity of the material inside the through floating. An object of the present invention is to provide a method for manufacturing a threaded float that can stably maintain the slanting of the threaded float.

  In order to solve the above-mentioned problems, the manufacturing method of the threading float of the present invention is a manufacturing method of the threading float provided with the threading hole through which the fishing line is inserted and the threading hole penetrating the shaft core. A step of providing a through hole along the central axis of the columnar body that is a base material of the floating body, a step of providing a locking portion that locks the float to a part of the through hole, A pipe having a diameter smaller than the diameter is inserted into the through hole, and a gap is formed between the pipe and the columnar body, and the pipe is fixed to the center of the through hole on the lower end side of the columnar body. Then, a step of covering the lower end of the void portion and a water-soluble curing agent containing powder of a substance having a specific gravity larger than that of the substance forming the columnar body are filled into the void portion from the upper end side of the void portion. Fixing the pipe to the center of the through hole on the upper end side of the step and the columnar body, Covering the upper end of the void portion, curing the water-soluble curing agent, and forming a specific gravity layer having a specific gravity greater than the substance forming the columnar body in the axial direction of the columnar body, The columnar body is shaped to produce a threaded float in which a specific gravity layer having a specific gravity larger than the material forming the threaded floating body is formed in the axial direction along the threading hole of the threaded floating body. It is characterized by doing.

  If a specific gravity layer with a higher specific gravity than the material forming the threaded floating body is formed in the axial direction along the threading hole of the threaded floating body, the The floating of the floating float can be suppressed, and the slanting of the floating floating can be stably maintained, so the food attached to the fish hook does not move unnaturally, and the fish feels strange and wary. There is an advantage that it is hard to give a heart.

  However, in order to realize this structure, it is necessary to satisfy the requirement of obtaining an appropriate buoyancy and balance in water. To that end, it is important to ensure the uniformity of the material inside the float. Accordingly, when an air layer is formed in the inside floating like the one described in Patent Document 1, moisture that has entered the inside floating is accumulated in this air layer, and the inside of the inside floating is Since it becomes a big factor which impairs the uniformity of a material, it is necessary to prevent generation | occurrence | production of such a situation.

  The manufacturing method of the center float according to the present invention forms a gap between the pipe and the columnar body, and contains a powder of a substance having a specific gravity greater than that of the substance forming the columnar body. By filling and curing with a water-soluble curing agent, a specific gravity layer is formed in the axial direction along the threading hole of the center floating body, and the water-soluble curing agent with high fluidity forms a void. It cures in the filled state. Therefore, an air layer is not formed in the inside floating, and even if the floating is thrown into the water, water does not enter, and appropriate buoyancy and balance in the water can be obtained. Moreover, since the waterproof property is high, it is possible to produce a float having excellent durability.

  In the method of manufacturing the center float according to the present invention, the step of fixing the pipe to the center of the through hole at the lower end side of the columnar body and covering the lower end of the gap is a through hole having the same diameter as the pipe. The disc-shaped center positioning jig provided at the center position is installed on the lower end side of the columnar body, and the pipe is passed through the through hole, and the pipe on the upper end side of the columnar body. The step of fixing to the center of the through hole and covering the upper end of the gap portion includes a disc-shaped center positioning jig provided with a through hole having the same diameter as the pipe at the center position on the upper end side of the columnar body. It can be done by installing and passing the pipe through the through hole.

  Since a pipe having a diameter smaller than the diameter of the through hole is inserted into the through hole and a gap is formed between the pipe and the columnar body, the pipe needs to be aligned with the axis of the columnar body. The pipe is fixed to the center of the through hole at the lower end side and the upper end side of the disc by using a disc-shaped center positioning jig having a through-hole having the same diameter as the pipe at the center position. Since this is done by passing the pipe through the through hole, the pipe can be easily and accurately aligned with the axis of the columnar body.

  In the method of manufacturing the through-floating of the present invention, in the step of filling the void portion with a water-soluble curing agent containing powder of a substance having a specific gravity greater than that of the substance forming the columnar body, the powder material Alternatively, the specific gravity of the heavy specific gravity layer can be adjusted by changing the content.

  The speed of the flow changes every day at the fishing site, and it is necessary to adjust the weight of the float in order to realize the ideal slanting of the float in this flow. In the through float manufacturing method of the present invention, the specific gravity of the heavy specific gravity layer can be adjusted by changing the material or content of the powder, so that the floating weight can be adjusted very simply. Therefore, by preparing a plurality of floats in which the specific gravity of the heavy specific gravity layer is finely adjusted, it is possible to realize ideal slanting of the float even with respect to the flow speed that changes every day.

  In the method of manufacturing the through hole according to the present invention, the step of providing the locking portion for locking the floating stopper to a part of the through hole is used in the step of providing the through hole along the central axis of the columnar body. After providing a large-diameter hole from the lower end side of the columnar body using a drill having a larger diameter than the drill, a part on the lower end side of the large-diameter hole is formed of the same material as the columnar body, The engaging member having a central hole having the same diameter as the through-hole can be fitted from the lower end side of the large-diameter hole to form a locking portion.

  Although it is necessary for the ideal slanting of the float that the position of the latching portion that latches the float is the center of gravity of the float, if the latch is formed by this method, the latch Since the weight portion can be formed integrally as a part of the heavy specific gravity layer, the position of the locking portion can be realized as the position of the center of gravity of the float by a simple method.

  According to the present invention, it is possible to suppress the floating of the floating through of the slanting line with respect to the slanted line of the floating through hole while ensuring the uniformity of the material inside the floating through hole, and to stabilize the slanting of the floating through hole. Therefore, it is possible to realize a manufacturing method of a continuous float that can be maintained at a high level.

It is a figure which shows the manufacturing process of the penetration float which concerns on embodiment of this invention. It is a figure which shows the manufacturing process of the penetration float which concerns on embodiment of this invention. It is a figure which shows the manufacturing process of the penetration float which concerns on embodiment of this invention.

Below, the manufacturing method of the through float of this invention is demonstrated based on the embodiment.
FIG. 1 to FIG. 3 show the manufacturing process of the center float according to the embodiment of the present invention.

  FIG. 1A shows a columnar body 1 serving as a base material for a floating body, and FIG. 1B shows that a threading hole through which a fishing line is inserted penetrates the axis of the floating body. FIG. 1C shows a drill used in the process of providing the through hole 2 along the central axis of the columnar body 1. The process of providing the large-diameter hole 3 from the lower end side of the columnar body 1 to the middle of the columnar body 1 is shown using a drill having a larger diameter. Thereby, the lower end side of the through hole 2 has a structure in which a large diameter hole 3 having a diameter larger than that of the through hole 2 is provided.

  FIG. 1 (d) shows a fitting member 5 formed of the same material as the columnar body 1 and having a central hole 4 having the same diameter as the through hole 2. This fitting member 5 is shown in FIG. 1 (c). As shown by the arrow, it is fitted from the lower end side of the large diameter hole 3 to a part of the lower end side of the large diameter hole 3, and as shown in FIG. A locking portion 6 to be stopped is provided.

  2 (a) is the same as that shown in FIG. 1 (e), and FIG. 2 (b) is the same diameter as the hollow pipe inserted through the through hole 2 in the subsequent process. A disk-shaped center positioning jig 8 in which a hole 7 is provided at the center position is shown. The outer diameter of the center positioning jig 8 is set to be the same as the outer diameter of the columnar body 1. The center positioning jig 8 is installed on the lower end side of the columnar body 1 as indicated by an arrow in FIG. FIG. 2C shows a state where the center positioning jig 8 is installed on the lower end side of the columnar body 1. FIG. 2D shows a process of passing the pipe 9 through the through hole 7. By using the center positioning jig 8, the pipe 9 is accurately fixed to the center of the through hole 2 on the lower end side of the columnar body 1, and the lower end of the gap 10 is covered with the center positioning jig 8. .

  As shown in FIG. 2 (d), a gap 9 is formed between the pipe 9 and the columnar body 1 by inserting a pipe 9 having a diameter smaller than that of the through hole 2 into the through hole 2. In this state, as shown in FIG. 3A, a water-soluble curing agent containing powder of a substance having a specific gravity greater than that of the substance forming the columnar body 1 is applied to the gap 10 from the upper end side of the gap 10. Fill.

  Metal powder, other inorganic powders, or organic powders can be used as the powder of a substance having a specific gravity greater than that of the substance forming the columnar body 1, such as volcanic ash existing in nature. Mixture powders can also be used. Whichever powder is used, it is only necessary to form a heavy specific gravity layer 11 having a specific gravity larger than that of the substance forming the columnar body 1 described later.

  Thereafter, as shown in FIG. 3B, the center positioning jig 8 is installed on the upper end side of the columnar body 1, and the pipe 9 is passed through the through hole 7. Accordingly, the pipe 9 is fixed to the center of the through hole 2 on the upper end side of the columnar body 1, and the upper end of the gap portion 10 is covered with the center positioning jig 8.

  By curing the water-soluble curing agent, as shown in FIG. 3C, a heavy specific gravity layer 11 having a specific gravity larger than that of the substance forming the columnar body 1 is formed in the axial direction of the columnar body 1. Thereafter, the center positioning jig 8 is removed, and as shown in FIG. 3D, the columnar body 1 is shaped into a spheroid or egg shape, and then the surface is waterproofed with waterproof paint or the like. In this way, the threading float 14 is manufactured in which the specific gravity layer 11 having a specific gravity larger than the material forming the threading floating body 12 is formed in the axial direction along the threading hole 13 of the threading floating body 12. Can do.

  In the area of the locking part 6 that locks the float, the thickness of the heavy specific gravity layer 11 is increased more than the other parts because the area of the locking part 6 passes through the center of gravity of the floating body 12. Because. Since the region where the locking portion 6 for locking the float is provided becomes the center of gravity position of the floating body 12, the region of the locking portion 6, which is the center of gravity position, becomes the center of rotation, and the seesaw principle operates. In this way, the mechanism is slanted in the direction in which it sinks and flows, and the fish is pulled in while being slanted in the direction in which the fish is drawn into the water. Therefore, no resistance is generated when the floating float is standing upright, and the fish does not feel uncomfortable. In addition, since the mechanism flows while pulling the floating, the mechanism can be tensioned, and the changing resistance given by the refraction and curvature of the mechanism when the fish caught by the needle is reversed can be reduced.

  Here, the detailed shape of the latching portion 6 is not specified, and the region of the latching portion 6 is floated by the above-described manufacturing method regardless of the specific shape of the latching portion 6. It only needs to be 12 gravity center positions.

  In the above-described manufacturing method of the through float of the present invention, the gap portion 10 is formed between the pipe 9 and the columnar body 1, and the specific gravity of the gap portion 10 is larger than that of the substance forming the columnar body 1. By filling with a water-soluble curing agent containing powder of the substance and curing, the heavy density layer 11 is formed in the axial direction along the threading hole 13 of the center floating body 12 and is fluid. Since a high water-soluble curing agent cures in a state in which the gap portion 10 is filled, an air layer is not formed in the inside floating 14, and even if the inside floating 14 is put into water, There is no infiltration. Therefore, proper buoyancy and balance in water can be obtained. Moreover, since the waterproof property is high, it is possible to produce a float having excellent durability.

  In addition, since the pipe 9 having a diameter smaller than the diameter of the through hole 2 is inserted into the through hole 2 and the gap 10 is formed between the pipe 9 and the columnar body 1, the pipe 9 is connected to the axis of the columnar body 1. Although it is necessary to match with the core, fixing the pipe 9 to the center of the through hole 2 between the lower end side and the upper end side of the columnar body 1 is a disk in which a through hole 7 having the same diameter as the pipe 9 is provided at the center position. Since the pipe-shaped center positioning jig 8 is installed on the lower end side or the upper end side of the columnar body 1 and the pipe 9 is passed through the through hole 7, the pipe 9 can be easily and accurately used as the axis of the columnar body 1. Can be matched.

  Moreover, since the specific gravity of the heavy specific gravity layer 11 can be adjusted by changing the material or content of the powder added to the water-soluble curing agent, the floating weight can be adjusted by a very simple operation. Can do. Therefore, by preparing multiple floats with specific gravity of the heavy specific gravity layer 11 finely adjusted at the fishing spot, the ideal drift of the float can be achieved even with the flow speed that changes every day. it can.

  Further, it is necessary for the ideal position of the float to be located at the center of gravity of the float, so that the latch portion 6 is formed by the above-described method. Then, since the weight part of the latching | locking part 6 can be integrally formed as a part of heavy specific gravity layer 11, it can implement | achieve the position of the latching | locking part 6 to the gravity center position of a float by a simple method. When attaching the weight part as a separate body as in the conventional float, if the weight part is enlarged and the float is heavy, the shape and size of the float will be restricted by the presence of the weight part. However, according to the manufacturing method of the present invention, the weight portion of the locking portion 6 can be integrally formed as a part of the heavy specific gravity layer 11, so that it is difficult to receive such restrictions, and the shape and size of the float The degree of freedom can be increased.

  The present invention can suppress the floating of the floating float with respect to the slanting line of the through floating while ensuring the uniformity of the material inside the through floating, and the slanting of the floating through can be stably performed. It can be widely used as a manufacturing method of a continuous float that can be maintained.
