Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lure for fishing, in which a spherical weight is provided inside a lure main body so as to be rollable in the front-rear direction.

[0002]

2. Description of the Related Art Conventionally, as this type of lure, there is one disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 8-205712. As shown in FIGS. 8 and 9, this lure 101
Luer body 1 made of synthetic resin into a roughly hollow shape
02 and a lip (dive plate) 103 protruding from its front
And a fishing line connecting portion (not shown) for tying the fishing line 104 to an appropriate position of the lip 103 is provided. Hook locking portions 105 and 106 are formed on the abdomen and tail of the lure main body 102, and hooks (hook needles) 107 are locked on these hook locking portions 105 and 106, respectively.

Reference numerals 108 and 109 denote spherical weights made of a metal having a large specific gravity such as lead or tungsten, and 110 denotes a guide on which the weights 108 and 109 roll. A locking rib 11 is provided at the front end of the guide 110 for locking the weight bodies 108 and 109 so as to be detachable.
1 is formed. An upper rib 112 is formed above the guide 110, and an inclined rib 113 is formed from a front end of the upper rib 112 to a rear portion of the hook locking portion 105. A side guide 114 is formed.
Guide the weights 108 and 109 from both sides (see FIG. 9).

[0004] The above lure body 102 is usually
It is formed by joining a pair of synthetic resin molded parts having a shape vertically divided right and left along the center line 115 (see FIG. 9) by heat welding or an adhesive. The guide 11
0, locking rib 111, upper rib 112, inclined rib 113,
The side guides 114 and the like are integrally molded when molding the synthetic resin molded part.

[0005] In the lure 101, the weights 108 and 109 are rearward (the hook locking portions 106) during casting.
Side) to shift the center of gravity toward the rear, so that a long flight distance can be obtained. On the other hand, during electrophoresis after landing, the weight body 108,
Since 109 moves over the locking rib 111 and is held in the space in front of it, the center of gravity is shifted forward, and as a result, the electrophoresis posture and the electrophoresis operation are improved.

In general, in order to achieve both good flight distance during casting and good posture and operation during electrophoresis, the lure body should be made as light as possible and the weight body should be made as heavy as possible. Is desirable.

On the other hand, in the conventional lure 101, since the specific gravity of the synthetic resin used for molding the lure main body 102 is relatively large, it is necessary to sufficiently reduce the weight (ie, reduce the apparent specific gravity) of the lure. The outer shell of the body 102 must be quite thin. However, in terms of molding difficulty and strength, there is a limit to the thickness of the lure, so that the lure main body 102 becomes heavy, and the posture and operation at the time of electrophoresis are further deteriorated.

Therefore, a lure in which a rollable weight body is built in the same manner as described above in a lure body formed by shaving a lightweight material such as wood or a foamed synthetic resin material has been considered. FIG.
Shows such a conventional lure 201. The lure main body 202 has a head 2 cut from wood.
03 and the body 204 are joined to each other with an adhesive or the like. 205 is a fishing line connecting portion, and 206 and 207 are hook engaging portions.
It is composed of a screw with a ring screwed into the 02.

A hollow section 208 having a circular cross section extending in the front-rear direction is formed in the inside of the lure body 202, and accommodates iron spherical weight bodies 209 and 210 therein. 211 is a magnet fixedly provided near the front end of the hollow portion 208, and 212 is a filler filled in a space in front of the magnet 211.

Also in this lure 201, the weights 209 and 210 are rearward (the hook locking portions 207) during casting.
Side), the flight distance increases, and at the time of electrophoresis after landing, the weights 209, 2
Since 10 is held at the front position, the center of gravity is shifted forward, and the electrophoretic posture and the electrophoretic operation are improved.

[0011]

However, in the conventional lure 201, the weights 209 and 210 are limited to iron because of the attraction by the magnet 211, and lead or tungsten having a specific gravity larger than iron is used. Cannot be used, and the diameters of the weights 209 and 210 cannot be increased unnecessarily due to dimensional restrictions of the lure body 202 and the like. Therefore, the lure body 202 can be reduced in weight as compared with the synthetic resin lure 101,
The weights 209 and 210 cannot be made sufficiently heavy,
After all, there was a problem that the flight distance and the electrophoresis operation were not good.

Incidentally, this lure 201 also does not have the magnet 211, but instead has a projection or the like near the front end in the hollow portion 208 which can lock the weight body like the locking rib 111 of the lure 101. It is also conceivable to form a locking portion (not shown) so that the weight is locked at a position closer to the front by the locking portion during electrophoresis. By doing so, a sufficiently heavy weight body 2 made of lead, tungsten, etc.
It goes without saying that 09 and 210 can also be used.

However, in reality, the hollow portion 208
Is the torso 2 before being joined to the head 203 as shown in FIG.
04 was formed by drilling from the direction indicated by the arrow in the figure, and it was almost impossible to form the above-described locking portion integrally with the body portion 204.

Further, instead of the lure main body 202 being composed of the head 203 and the trunk 204, a pair of divided main bodies in which the lure main body is vertically divided into left and right are made of wood, and each of the divided main bodies is made of wood. A semi-circular groove is formed on the joint surface, and a structure is adopted in which when the divided main bodies are joined to each other to form a lure main body, the semi-circular grooves face each other to form a hollow portion having a circular cross section. It is also possible. But,
In this case, since the semicircular groove is dug with a chisel or the like, the accuracy of the shape of the hollow portion is lower than in the case of drilling, and the rolling of the weight may not be smooth. Also in this case, it is difficult to form the above-described locking portion with high accuracy in terms of processing technology.

For the above reasons, in the case of a lure in which a lure body is formed by shaving a lightweight material such as wood or foam synthetic resin material, it is inevitable to adopt a configuration in which the weight is attracted by using a magnet. However, the fact was that the weight could not be made sufficiently heavy.

The present invention has been made in view of the above circumstances, and even when a lure body is formed by cutting a lightweight material such as wood or a foamed synthetic resin material, a sufficiently heavy weight body can be formed. It is an object of the present invention to provide a lure that can be used, can increase the flight distance during casting, and can improve the posture and operation during electrophoresis.

[0017]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a lure body having a fishing line connecting portion at a front end thereof, and a luer body provided inside the luer body so as to be rollable in the front-rear direction. In a lure having a spherical weight body, a cylindrical member having an inner diameter larger than the diameter of the weight body, and having a locking portion at one end side for removably locking the weight body. It is formed separately and independently from the lure main body, and the weight body is accommodated inside the tubular member, and is embedded in the lure main body with the locking portion facing forward.

Further, in the above structure, the locking portion is constituted by a hole formed in the peripheral wall of the cylindrical member to have a size and shape to engage with the weight body.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A lure according to an embodiment of the present invention will be described below with reference to FIGS. This lure 1
The lure body 2 has a center line 3 (FIG. 2).
(See FIG. 2). Each divided body 2a, 2b
Is formed by shaving a lightweight material such as wood or a foamed synthetic resin material. As the wood, for example, very light balsa wood or paulownia wood is suitable. Further, as the foamed synthetic resin material, for example, a foamed urethane material can be used.

When the divided main bodies 2a and 2b are bonded to each other with an adhesive to form the lure main body 2, a cylindrical member 6 accommodating the weights 4 and 5 therein is interposed between the divided main bodies 2a and 2b. , The frame 7 and the auxiliary weight body 8 are sandwiched. Referring mainly to FIG. 4, the weight members 4 and 5 are made of a metal having a relatively large specific gravity, such as lead or tungsten, and are formed in spherical shapes having the same diameter. The cylindrical member 6 is provided with the weights 4 and 5.
It has an inner diameter slightly larger than the diameter of the cylinder, and is formed in a cylindrical shape with both ends opened. The material of the tubular member 6 formed separately and independently from the lure main body 2 is arbitrary, but a material having a certain strength and lightness is desirable, and for example, a light metal such as aluminum or a hard synthetic resin is suitable. .

As shown in FIGS. 4 and 5, a hole 9 (an engagement portion) having a size and shape for engaging with the weights 4 and 5 is formed on a peripheral wall of the cylindrical member 6 at a position close to one end opening. ) Is drilled. Here, the “size and shape to be engaged with the weights 4 and 5” means that the weights 4 and 5 cannot pass through, but the weights 5 (or 4) fit into the holes 9. When inserted, it refers to a size and shape that can hold the fitted weight body until the cylinder center direction of the tubular member 6 is inclined from horizontal to some extent. In this embodiment, the hole 9 is formed in a substantially elliptical shape whose major axis direction is orthogonal to the cylinder center direction of the tubular member 6 as shown in FIG. As shown in FIG. 5, when the weight 5 is fitted into the hole 9,
The weight body 4 is set at a position such that the weight body 4 just fits between the cylindrical member 6 and one end opening of the cylindrical member 6.

Each of the divided main bodies 2a and 2b is formed with a semicircular groove 10 having a length substantially equal to that of the cylindrical member 6.
A tubular member having a hole 9 facing forward and downward in a hollow portion having a circular cross section formed by opposing both semicircular grooves 10 in a state where the luer body 2 is formed by laminating the divided main bodies 2a and 2b. 6 are accommodated almost without gaps. Thus, the tubular member 6 is embedded in the lure main body 2. In addition,
10a is a weight body fitted into the hole 9 and the divided main bodies 2a, 2
b so that it does not interfere with
a, 2b.

The frame 7 is formed by bending a single wire (stainless steel wire) into a predetermined shape. The frame 7 has a fishing line connecting portion 11 and hook engaging portions 12 and 13 which are integrally formed. An auxiliary weight body 14 made of a metal such as lead is fixed near the stop portion 13. The fishing line connecting portion 11 and the hook locking portions 12, 13 are sandwiched between the divided main bodies 2a, 2b in a state where they are exposed to the outside. The auxiliary weight body 8 is formed in a spherical shape from a metal such as lead, and is sandwiched between the divided main bodies 2a and 2b. In addition, similarly to the case where the semicircular groove 10 corresponding to the cylindrical member 6 is formed, a concave portion corresponding to the frame 7 and the auxiliary weight body 8 is also formed on the joint surface of the divided main bodies 2a and 2b. As a result, the divided main bodies 2a and 2b can be stuck together without any gap.

After the lure main body 2 is formed from the divided main bodies 2a and 2b as described above, the lip 15 is fixed to the lower portion of the front end thereof, and the surface of the lure main body 2 is provided with patterns such as eyes and scales. Painted and hook hook 1
A hook 17 is locked to each of the hooks 2 and 13 via a ring 16.

This lure 1 is, as shown in FIGS. 6 and 7,
It is used by connecting the tip of the fishing line 18 to the fishing line connecting portion 11. Then, when the lure 1 enters a casting system in which the lure 1 is hung down with the fishing line 18 which is shortly protruded from the rod tip, the lure 1 is hung with the fishing line connecting portion 11 up as shown in FIG. , 5 move to the rear end (the end on the hook locking portion 13 side) in the tubular member 6, and the center of gravity moves toward the rear. Therefore, if the casting is performed from this state, it is possible to fly sufficiently far.

Further, when the cast lure 1 lands, due to the impact at the time of landing, or the force of the water applied to the lip 15 when the fishing lure 18 is pulled by the fishing line 18 and migrates, the lure 1 is lubricated.
Is slightly lower than the horizontal, and the weights 4, 5
Rolls forward in the tubular member 6 (toward the fishing line connecting portion 11). At this time, the weight body 4 may be pushed by the weight body 5 from behind, so that the weight body 4 goes over the hole 9 and further moves forward. Hole 9
It does not proceed further forward, but is fitted and locked in the hole 9 as shown in FIG. As a result, the center of gravity of the lure 1 becomes closer to the front, and the lure main body 2 performs a swinging movement around the center of gravity, so that a favorable electrophoresis operation that can attract the interest of the target fishing fish is achieved. Further, since the center of gravity is shifted toward the front, even if the lure 1 is pulled obliquely upward by the fishing line 18, the lure 1 does not turn upward and jump out of the water surface S, and the electrophoresis posture is good.

In the lure 1 of this embodiment described above, since the weights 4 and 5 are accommodated in the cylindrical member 6 having the hole 9 (locking portion), the lure main body 2 is Despite being formed by shaving a lightweight material such as wood or a foamed synthetic resin material, the weights 4 and 5 can be locked without using a magnet. Therefore, by forming the weights 4 and 5 from a metal such as lead or tungsten having a higher specific gravity than iron, the weight can be made sufficiently large. At a high level.

Further, even if the semicircular groove 10 has a poor shape accuracy and its inner surface is uneven, the weights 4 and 5 roll on the inner wall surface of the cylindrical member 6. The rolling is performed extremely smoothly. Therefore, since it is not necessary to form the hollow portion for accommodating the weight body with high precision as in the prior art, the lure main body 2 can be composed of the divided main bodies 2a and 2b vertically divided into right and left. The frame 7 can be buried, which was impossible in the case of 201, and the strength is improved.

It is needless to say that the present invention is not limited to the above-described embodiment.
Is optional. Further, the number of weight bodies accommodated in the cylindrical member 6 is not limited to two, and may be one or three or more.

Further, the locking portion for locking the weight body is not limited to the hole 9 but protrudes from, for example, an inner wall near one end of the cylindrical member to a height at which the weight body can be locked. The locking portion may be constituted by a projection. Further, the locking portion may be formed by a concave portion formed on the inner wall surface near one end of the tubular member and capable of locking by dropping the weight. However, in the case where the locking portion is formed by the protrusion or the concave portion, the operation of forming the protrusion or the concave portion on the tubular member becomes slightly difficult. On the other hand, if the hole 9 is used, it can be easily formed in a tubular member obtained by cutting a commercially available pipe or the like, and the manufacturing cost can be reduced.

[0031]

As described above, in the lure according to the present invention, the lure has an inner diameter larger than the diameter of the weight, and the weight is detachably engaged with one end of the lure. Since a tubular member having a stop portion is formed separately and independently from the lure main body, the weight body is accommodated inside the tubular member and embedded in the lure main body with the locking portion facing forward, Even when a lure body is formed by cutting a lightweight material such as wood or foam synthetic resin material, a sufficiently heavy weight body formed of a metal such as lead or tungsten having a larger specific gravity than iron can be used. . Therefore, the lure body can be made as light as possible and the weight body can be made as heavy as possible. As a result, it is possible to obtain a lure in which the flight distance during casting and the posture and operation during electrophoresis are compatible at a high level.

In the case where the locking portion is constituted by a hole formed in the peripheral wall of the cylindrical member so as to be engaged with the weight body, the locking portion is constituted by, for example, a projection or a concave portion. The locking portion can be formed more easily than in the case, and the production cost of the lure can be reduced.
