TECHNICAL FIELD OF THE INVENTION
The present invention relates to a float used when fishing in a sea, a river, a lake, a pond, or the like, and a method of adjusting the buoyancy of the fishing float.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a fishing float of this type, there is known a wooden float in which natural wood such as paulownia is cut and subjected to water-resistant coating on its surface. In actual use of the float, the buoyancy balance is extremely important, and significantly affects the movement of the float, the hitting sensitivity, and the like.
[0003]
Conventionally, when adjusting the buoyancy of a float, for example, a wooden material of a wooden float is formed into a float (outer shape), and then a base coat is applied to the entire surface. In the case of the so-called through hole, a through hole is formed in advance. Next, the buoy is submerged in water to measure buoyancy, and the weight of the weight for obtaining the final buoyancy is determined based on the measured value. For example, in the case of a buoyancy measurement value of 1 g, in order to obtain a float with a target buoyancy of 0.5 g with respect to the buoyancy measurement value, a weight of 0.5 g is attached.
[0004]
A metal washer or the like is used as the weight for adjusting the buoyancy. The number and weight of the washers are appropriately selected so as to obtain a target buoyancy. An insertion hole for mounting a buoyancy adjusting washer is formed in the lower floating portion. The dimensions, especially the depth, of this insertion hole are determined according to the thickness of the washer to be mounted. For example, in the above-described example, a float having a target buoyancy of 0.5 g is obtained by using two 0.2 g weights and an adhesive for fixing these weights to the insertion holes.
[0005]
[Problems to be solved by the invention]
However, in the conventional floating or the method of adjusting the buoyancy of the floating, there is variation in the weight of the timber which is the material for forming the floating. For this reason, as described above, the number of buoyancy adjusting washers determined based on the result of buoyancy measurement, and thus the depth of the insertion hole, also varies as does the weight variation of the material timber. That is, the depth of the insertion hole must be individually set for each of the floats, and the insertion holes having different depths have to be formed.
[0006]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a buoyancy adjusting method for a fishing float that can accurately and efficiently adjust buoyancy.
[0007]
[Means for Solving the Problems]
The method of adjusting the buoyancy of a fishing float according to the present invention comprises measuring the floating buoyancy of the float main body in a state where a main weight is temporarily fixed to the insertion hole after plugging and coating an insertion hole formed in a lower portion of the float main body. The main weight is once removed, an auxiliary weight for obtaining a target floating buoyancy is mounted in the insertion hole, and the main weight is mounted and fixed again to generate a predetermined buoyancy.
[0008]
Further, the buoyancy adjustment method for a fishing float according to the present invention is a buoyancy adjustment method for a fishing float in which a weight is attached to a lower portion of the floating body so as to generate a predetermined buoyancy. A step of forming an insertion hole for use; a step of painting the floating body; a step of attaching a main weight to the insertion hole and temporarily fixing the main body to the floating body; A step of measuring the floating buoyancy of the floating main body, a step of setting the weight of the auxiliary weight so that a desired floating buoyancy is obtained based on the measured buoyancy, and the temporarily fixed main weight is removed from the floating main body. The step of detaching and attaching the weight-set auxiliary weight to the insertion hole and the step of fixing the main weight to the floating body are sequentially performed.
[0009]
In the method for adjusting the buoyancy of a fishing float according to the present invention, when the floating body is painted, an alternative member substantially equivalent to the main weight is temporarily fixed to the floating body.
[0010]
In the buoyancy adjusting method for a fishing float according to the present invention, the auxiliary weight includes at least a plurality of small weight pieces, and the total weight of the small weight piece and the adhesive applied to the insertion hole is equal to or smaller than the weight of the auxiliary weight. Set as weight.
[0011]
[Action]
According to the present invention, after the insertion hole formed in the lower portion of the floating main body is plugged and painted, the floating buoyancy of the floating main body is measured with the main weight temporarily fixed to the insertion hole. Next, by removing the main weight once and attaching an auxiliary weight for obtaining the target floating buoyancy to the insertion hole, a predetermined buoyancy can be generated. After the insertion hole is formed in advance, the floating buoyancy is measured in a painted state, so that accurate buoyancy can be obtained without being affected by the weight variation of the material timber at all. In this case, since the paint weight used in the painting process of the floating body is particularly taken into account in the measurement of the buoyancy, delicate buoyancy errors that may be caused by the paint weight are eliminated, and buoyancy with extremely high precision is realized. .
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a preferred embodiment of a buoyancy adjusting method for a fishing float according to the present invention will be described with reference to FIGS.
[0013]
FIG. 1 shows the appearance of a fishing float 10 in this embodiment. The float 10 has a float body 11 preferably made of a wood material such as paulownia. At the lower end of the floating body 11, a rubber foot 12 made of so-called EP rubber (ethylene propylene rubber) or the like is integrally provided. According to the rubber feet 12, excellent impact resistance can be obtained at the time of collision of the float 10 and the like, and an excellent appearance surface can be obtained without any special coating without any material. The surface of the floating body 11 is subjected to a predetermined coating process as described later.
[0014]
FIG. 2 shows the internal structure of the fishing float 10. A center pipe 13 is inserted through the float 10, that is, the center pipe 13 passes through the center of each of the float main body 11 and the rubber feet 12. An insertion hole 14 for mounting a weight or the like is formed at a predetermined depth in a lower portion of the floating body 11 as described later. A main weight having a predetermined weight, which will be described later, and an auxiliary weight whose weight is set in relation to the floating buoyancy when the main weight is mounted are mounted in the insertion holes 14.
[0015]
In FIG. 2, a main body screw 15 preferably made of brass is attached to the insertion hole 14. A rubber foot screw 16 preferably made of brass and integrated with the rubber foot 12 is screwed into the main body screw 15. In the present embodiment, the main weight is constituted by the main body screw 15 and the rubber foot screw 16.
[0016]
Further, a plurality of small weight pieces, that is, two metal (iron or brass) washers 17a and 17b and a foam rubber material 18 in this example are mounted in the insertion hole 14. These members constitute an auxiliary weight. The weight of the auxiliary weight is determined by the total weight of the washers 17a and 17b, the foamed rubber material 18, and the adhesive (not shown) applied to the insertion hole 14. The foamed rubber material 18 is a material in which a large number of air bubbles are independently contained in a rubber base material that is an elastic body, and the air bubbles are isolated from each other and have a non-water-impregnated structure. By providing the foamed rubber material 18, a certain buoyancy can be generated even if the float 10 is flooded.
[0017]
In the method of the present invention, first, a predetermined wooden material is cut to form the (outer) shape of the float 10. Next, a through hole for inserting the center pipe 13 is formed in the center of the floating main body 11, and an insertion hole 14 for attaching a weight is formed below the floating main body 11. The main weight and the auxiliary weight described above are mounted in the insertion hole 14, and the diameter and the depth thereof are set to predetermined dimensions in advance. The center pipe 13 is inserted into the through hole, and is fixed with an appropriate adhesive. The center pipe 13 is preferably made of, for example, a resin material.
[0018]
After the center pipe 13 is inserted and fixed, the main body screw 15 is inserted into the insertion hole 14 and fixed with an adhesive. The main body screw 15 is formed in an annular or ring shape. As shown in FIG. 3, the main body screw 15 has a screw portion 15a on an inner peripheral portion and an appropriate knurl 15b on an outer peripheral portion. By fitting the outer peripheral surface provided with the knurl 15b into the insertion hole 14, the main body screw 15 can be securely bonded and fixed.
[0019]
A rubber foot screw 16 integrated with the rubber foot 12 is coupled to the main body screw 15, but before that, an alternative member (hereinafter, referred to as a substantially equivalent) to the rubber foot 12 and the rubber foot screw 16. The insertion hole 14 is plugged by temporarily fixing the dummy body (which is called a dummy and has the same weight and shape) to the floating body 11. Then, after the dummy is temporarily fixed, the entire body together with the floating body 11 is painted by so-called dip pickling. In this manner, by temporarily fixing the dummy and performing the coating, the entire surface of the floating main body 11 is easily and appropriately coated.
[0020]
Here, the rubber foot 12 and the rubber foot screw 16 have a configuration in which the rubber foot screw 16 is inserted (see a two-dot chain line in FIG. 3) and integrated by compression molding. The rubber foot screw 16 has a screw portion 16a on an outer peripheral portion, and the rubber foot screw 16 is easily coupled to the main body screw 15 by screwing the screw portion 16a with the screw portion 15a of the main body screw 15. be able to.
[0021]
The dummy temporarily fixed to the body screw 15 is removed from the floating body 11, and then a rubber foot screw 16 is screwed to the body screw 15. In this case, the rubber foot screw 16 is temporarily fixed without using an adhesive. As a result, a main weight including the main body screw 15 and the rubber foot screw 16 is attached to the floating main body 11. Next, the floating main body 11 is submerged in water with the main weight temporarily fixed in this way, and the buoyancy at this time is measured. In this case, no auxiliary weight (such as washers 17a and 17b) is attached to the insertion hole 14, and the upper portion of the insertion hole 14 is hollow.
[0022]
Next, based on the measured buoyancy, the weight of the auxiliary weight is set so as to obtain a desired buoyancy. As described above, the weight of the auxiliary weight is set by the total weight of the washers 17a and 17b, the foamed rubber material 18, and the adhesive applied to the insertion hole 14. In this case, the floating body 11 has the rubber feet 12 and It is good to allow for the weight of the adhesive used to fix the rubber foot screw 16. The temporarily fixed rubber foot 12 and rubber foot screw 16 are temporarily removed, and the auxiliary weight whose weight is set as described above is adhesively fixed inside the insertion hole 14 with a silicon-based adhesive. Then, the rubber foot 12 and the rubber foot screw 16 are finally bonded and fixed to the floating body 11.
[0023]
As described above, the auxiliary weight is set so that the target buoyancy of the float 10 is obtained. Taking the measured buoyancy measurement value of 1 g as an example, in order to obtain a float of the target buoyancy of 0.5 g with respect to this buoyancy measurement value, a 0.5 g auxiliary weight is attached. In order to secure the weight of the auxiliary weight, two 0.2-g washers 17a and 17b, a foamed rubber material 18, and an adhesive for fixing these to the insertion hole 14 are used, so that a target buoyancy of 0. 5 g of float 10 are obtained.
[0024]
In the above embodiment, the target buoyancy of the float 10 or the weights of the washers 17a and 17b have been described using specific numerical examples, but the present invention is not limited only to these numerical examples. These numerical values can be appropriately changed as necessary, and in each case, the same operation and effect as the above embodiment can be obtained.
[0025]
【The invention's effect】
As described above, according to the present invention, the weight of the auxiliary weight is set so as to have the target buoyancy based on the floating buoyancy measured when the main weight is attached, and thereby, an accurate desired weight is set by the main weight and the auxiliary weight. Buoyancy can be obtained. In addition, since it is only necessary to form a fixed insertion hole for mounting the weight, the process can be made extremely efficient, and accurate buoyancy can be obtained without being affected by the weight variation of the material timber at all. It has the advantage of In this case, since the paint weight used in the painting process of the floating body is particularly taken into account in the measurement of the buoyancy, delicate buoyancy errors that may be caused by the paint weight are eliminated, and buoyancy with extremely high precision is realized. .
