Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weight for manufacturing a fishing tackle by hand and its construction method. The present invention is intended for making lure plugs by hand, but can also be used when making other fishing tackles by hand.

[0002]

2. Description of the Related Art Conventionally, when hand-made fishing tackle such as lumber and lures, the work of incorporating a weight into the fishing tackle body has been very complicated and troublesome. Conventionally, hollows such as holes and grooves are made inside the fishing tackle body cut out from wood etc., the weight is inserted and the gap is filled with adhesive, or the weight is enclosed by covering with the same material as the fishing tackle body. The way to do it was common. In addition, the weight used for the production of handmade fishing tackle was a commercially available plate weight, gundam, etc. deformed with pliers, a lead rod, etc.

In the prior art, when making fishing tackles by hand, the work of incorporating a weight in the fishing tackle body has become a bottleneck in overall design and fabrication. In most cases, in order to match the shape and size of the weight with the hollow part of the fishing tackle body containing the weight, the steps of deforming and shaping the weight with a file or pliers were indispensable. In addition, the design and manufacture of the hollow part that incorporates the weight of the fishing tackle body had to fully consider the shape and size of the commercially available weight. Further, as shown in FIG. 2 and FIG. 5, the insertion efficiency of the weight with respect to the volume of the hole and groove of the fishing tackle body is poor, so that it is difficult to form a high density portion and it is difficult to obtain the difference in internal density.

When making a lure plug by hand,
It is important to make a difference in the internal density of the plug body in order to improve the lure action with a strong restoring force. The laminated structure of the balsa material shown in FIG. 3 is often used in order to obtain the density difference inside the plug. The structure of FIG. 3 has a cross-sectional view as shown in FIG. 4 and is excellent in that density difference inside the plug is easily generated and the lure action is improved, but the manufacturing process is complicated and the production efficiency is very poor. The structure of FIG. 3 has to be carved on both left and right sides of the plug body (2) in which the internal structure wire (3) and the groove for enclosing the lead rod (8) as the weight are bonded to the plug body (2) such as balsa material. In addition, the step of adhering the internal structural wire (3) and the lead rod (8), which is a weight, with the balsa plug body (2) was necessary. In addition, carve a groove in the abdomen of the plug body (2) as shown in Fig. 2.
There is also a structure in which a deformed weight (7) such as a gundammer is inserted and the lid is filled with an adhesive, but the efficiency of enclosing the weight in the hollow portion of the fishing tackle body is poor, and the deformation of the weight is necessary. The efficiency of design and production was poor.

[PROBLEMS TO BE SOLVED BY THE INVENTION] [PROBLEMS TO BE SOLVED BY THE INVENTION] To provide a weight suitable for hand-made fishing tackle production, in which the work of incorporating the weight is simple and does not become a bottleneck in design and production. Further, in the case of manufacturing a lure plug, a method of making a high-performance plug more easily than the conventional method of bonding structure of FIG. 3 is also provided.

[0006]

Means for Solving the Problems Powder-like or granular high-density metal particles are directly used as a weight for producing a fishing tackle.
This is the powder weight (1) for handmade fishing tackle production. If the weight is made powdery and the properties of the powder are used, the work of incorporating the weight can be simplified and the bottleneck in design and manufacturing can be avoided.

If the weight is in the form of powder, the weight need not be deformed or shaped. In addition, the weight can be easily inserted and built into the hollow part of the fishing tackle body of any shape and volume. Therefore, the bottleneck in designing and manufacturing the fishing tackle body due to the shape and size of the commercially available weight, which has been conventionally used, can be significantly alleviated.
Furthermore, since it is possible to easily build a high-density weight in the hollow part of the fishing tackle body to the limit of the volume, it is also suitable for the production of fishing tackles that require a difference in internal density for actions such as lures and balance.

In particular, when the lure plug is manufactured by hand, the structure of FIGS. 6 and 7 which cannot be manufactured by the conventional weight by the powder weight (1) for manufacturing the fishing tackle can be realized. This structure is simpler to design and manufacture than the conventional structures shown in FIGS. 3 and 4, and moreover, the weight can be inserted more densely under the plug than the conventional bonding structure shown in FIG. Therefore, the resilience at the time of lure action is strong, and excellent lure action can be realized.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In order to carry out the present invention, it is convenient to use tungsten powder for powder metallurgy as a powder weight (1) for making a fishing tackle in a bottle (4) with a nozzle having a large nozzle hole. is there. The metal used may be lead, brass, etc., but tungsten is suitable because of environmental considerations and specific gravity. The finer the particles of the tungsten powder to be used, the better, but it is possible to use it from a diameter of about 0.5 mm. If the particles of the tungsten powder used are too coarse, the gap between the tungsten particles will become too large when they are built into the fishing tackle body, resulting in a decrease in the density of the weight enclosed and a problem of uneven processing of the externally exposed surface of the weight. The powder before and after is preferable. This handmade fishing tackle manufacturing powder weight (1) is inserted from the bottle with nozzle (4) into the hollow part such as a hole or groove of the fishing tackle body by using the property of the powder, and is packed and fixed with an instant adhesive or the like, to the fishing tackle body. A weight can be built in easily. It should be noted that this handmade fishing tackle manufacturing powder weight (1) and its manufacturing method can be applied to most handmade fishing tackles, and there is no precedent for powdered or granular handmade fishing tackle manufacturing weights.

For example, when making a plug by hand, a groove having an appropriate width and depth is formed on the abdomen of the plug body (2) carved out of wood or the like with a router, a chisel, etc. as shown in the horizontal sectional view 6 and the vertical sectional view 7. Engrave, insert the internal structure line (3), and fix it in place with instant adhesive.

Next, as shown in FIG. 1, an appropriate amount of a powder weight (1) for making a handmade fishing tackle from a bottle (4) with a nozzle is attached to the plug body (2) of the abdomen of the plug body (2) by utilizing the property of powder. Insert it into the groove and squeeze it as close as possible to the volume of the groove. Then, the weight can be easily built in the fishing tackle body by smoothing the irregularities on the externally exposed surface of the handmade fishing tackle manufacturing powder weight (1) and fixing it with an instant adhesive, or by covering with a cover such as wood. Subsequent manufacturing steps may be performed by coating, coloring, etc. as in the conventional case.

In order to adjust the insertion amount of the weight, it is adjusted by the depth and width of the hole or groove into which the weight is inserted. If further fine adjustment is required, it is sufficient to make a hole with a fine drill and repeat the work of incorporating the weight.

Due to the above, the powder weight for making handmade fishing tackle (1)
By using, the weight can be enclosed and built into the handmade fishing tackle more efficiently and with higher performance than the conventional technology. Also, a low center-of-gravity structure as shown in FIGS. 6 and 7 makes it easy to manually make a plug excellent in action.

[0014]

As described above, according to the present invention, the bottleneck in designing and manufacturing due to the work of incorporating the weight is alleviated when the handmade fishing tackle is manufactured, and the overall design and manufacturing becomes simple and efficient. When making lure plugs, you can easily make high-performance plugs. The invention has the following advantages in particular:

(A) The efficiency of designing and manufacturing a handmade fishing tackle is significantly improved. The bottleneck problem of designing and manufacturing by the conventional work of incorporating the weight is solved. In particular, when manufacturing a lure plug, by adopting a structure as shown in FIG. 6 and FIG. 7, it becomes possible to easily make a plug having superior motility as compared with the conventional one, and the conventional cumbersome bonding structure of FIG. Since production is unnecessary, the production efficiency is significantly improved.

(B) Deformation processing of the weight is not necessary, and it is possible to use only the powder weight. It eliminates the need for shaping and deforming the weight built into the fishing tackle body, improving manufacturing efficiency. In addition, it is not necessary to prepare several kinds of weights according to size, and only the powder weight (1) for handmade fishing tackle production can be used.

(C) Since the weight can be freely arranged, it becomes easy to realize a physically optimal structure. When making a lure plug, an ultra-low center-of-gravity structure can be realized by arranging weights as shown in FIGS. 6 and 7, which has been impossible in the past because of being hindered by the internal structure line (3). Since the weight can be built into the plug just below the plug at a high density, the downward restoring force of the plug becomes strong, so that the action of the lure is significantly improved as compared with the pasted bonding structure of FIG.

(D) It is possible to efficiently enclose the weight in the hollow portion of the fishing tackle body and enclose a large amount of the weight. The amount of weight that can be built in the hole drilled is the powder weight (1) for making handmade fishing tackle shown in Fig. 5.
8 is compared with the case where the spherical weight (9) of FIG. 8 is used, the powder weight (1) for making handmade fishing tackles is far more numerous.

(E) It becomes possible to easily insert the weight into the details and finely adjust it, which has been impossible in the past. For example, since the weight can be inserted to the limit of the volume even in the hole of a drill with a diameter of 1 mm,
It is possible to insert a weight into a small part of fishing tackle, which was not possible in the past, and fine adjustment is easy.

(F) It is possible to easily realize a center-of-gravity moving mechanism that was difficult with a handmade plug. When making a lure plug, if you insert the handmade fishing tackle manufacturing powder weight (1) with an adhesive and leave the appropriate hollow part and cover it with wood etc., it is difficult to make the center of gravity mechanism by hand. Can be easily created.

(G) It is possible to improve the strength of the fishing tackle body and reinforce the internal structure line. Since the powder weight (1) for making a fishing tackle, which is fixed with an adhesive, hardens, the strength of the fishing tackle body can be improved. Further, in the case of a lure plug, as shown in FIG. 5, if the branch portion and the end portion of the internal structure wire are put in the portion that is hardened by the adhesive, it is not necessary to reinforce the internal structure wire (3) with a thread or the like. Become.

(I) Low cost and environmentally friendly. Since the powder weight (1) for making handmade fishing tackle can use the powder of tungsten for powder metallurgy, the cost is much lower than that of the weight made of tungsten for shaving or casting. Also, since it is tungsten, it has far less impact on the environment than lead weights.

(Nu) Various other applications are possible. The powder weight (1) for making handmade fishing tackle can be used as a bait tree for squid fishing, a rod grip, a weight for a balancer of a squid, and a sounding material for a fish collecting sounder, in addition to a lure plug. It is also convenient for suspend tuning because the buoyancy can be easily adjusted simply by making a hole in the back of a commercially available plug with a drill and filling it with the handmade fishing tackle manufacturing powder weight (1).
