Abstract
Description
Technical Field
[0001] The present invention relates to a fishing lure, and particularly to a fishing lure based on a wooden material that may be evaluated for buoyancy and design in water.
Background Art
[0002] A fishing lure not only adopts a structure that can improve fishing results, but on the other hand, there are also many fishermen who are particular about its design and decoration from the perspective of a hobby. As something that meets such two-sided requirements, a wooden lure that is close to handmade is supported by fishermen who pursue interest (see, for example, Patent Document 1). That is, being made of wood first increases the buoyancy of the entire lure, thereby increasing the suitability and stability of lure operation, and an effect of making it easier to improve fishing results can be expected.
[0003] In addition, in the case of a wooden lure, in addition to the fact that various decoration methods such as various coatings for its surface decoration can be adopted, the wooden material is easy to process, and fishermen themselves can craft a lure with a shape and decoration that suits their own preferences.
[0004] On the other hand, such a handmade lure with enhanced hobby characteristics is called a handmade craft and becomes a so-called one-of-a-kind item, so it becomes very expensive. In addition, when using it, there is a problem that its surface decoration and the like are easily damaged. Such damage poses a problem for fishermen who painstakingly made the wooden lure, forcing them to perform regenerative decoration and repair, or causing great psychological disappointment.

Embodiments for Carrying Out the Invention
[0018] Hereinafter, the fishing lure of the present invention will be specifically described based on the illustrated embodiments. It should be noted that technical modifications within the scope of the technical idea of the present invention can also be made to this embodiment.
Embodiment
[0019] The main configuration of the fishing lure 1 of the present invention, as shown in FIGS. 1 and 2, has a body main body 5 including a body core 2 imitating the general shape of the body of a fish and a surface shell 3 protecting the body core 2. The body core 2 is made of a woody material having a lower specific gravity than water. On the other hand, the surface shell 3 covers the body core 2 and holds a plurality of eyes 11. The body main body 5 constituted by the surface shell 3 and the body core 2 is configured such that the body core 2 fits tightly into the internal space constituted by the surface shell 3, and this is defined as an apparent solid. Each component will be described below.
[0020] First, as the overall configuration of the fishing lure 1, for example, three eyes 11 for attaching a fishing line, a hook 6, and a snap ring 7 are provided at three locations. That is, there are three locations: a head eye 11A, a belly eye 11B, and a tail eye 11C. Of course, the arrangement and number of the eyes 11 can be selected according to the target fish for the intended fishing result, such as providing eyes 11 at other parts. Regarding the eye 11, the part that protrudes outward from the body main body 5 of the fishing lure 1 and exhibits the original function of locking the fishing line, the hook 6, and the snap ring 7 is shown as a functional part 11f, and the part held on the side of the body main body 5 is shown as an assembly part 11p.
[0021] Furthermore, as the overall configuration of the fishing lure 1, a lip 12 with its tip facing downward is provided at the front end, that is, below the head (lower jaw part) of the fish body. Also, a weight 13 is provided inside, slightly rearward from the center of the abdomen.
[0022] Next, the body core 2 will be described. The body core 2 is a muk body made of a wood material, and paulownia wood is preferable as a specific material. The biggest reasons are that it is lightweight and easy to process. Therefore, it is also possible to apply balsa wood or the like having similar properties. Of course, it is also possible to use laminated wood instead of solid wood. As shown in FIG. 4, the specific shape of the body core 2 can be expressed as a streamlined shape that tapers from front to back, imitating the general shape of the body of a fish. In this embodiment, a recess 21 for an eye holder corresponding to the eye holder 31 (abdominal eye holder 31B) in the outer shell 3 described later is formed at the center of the lower part.
[0023] On the other hand, a fish attracting pattern 22 is provided on the side surface of the body core 2 (see FIGS. 1 and 2). The fish attracting pattern 22 is formed by painting directly on the side surface of the body core 2, or by attaching a seal-like decorative sheet or the like on which a pattern or the like is printed. The pattern itself adopts a pattern of a small fish liked by the target fish for fishing, or a pattern such as a shiny, so-called glittery pattern like an abalone shell. Furthermore, as the fish attracting pattern 22, a metal foil such as aluminum or gold can also be adopted. Furthermore, a recess 23 for holding the weight 13 is formed at a position near the rear of the lower surface of the body core 2, and in this embodiment, it is formed at two locations.
[0024] Next, the outer shell 3 that wraps the body core 2 will be described (see FIGS. 2 and 3). The outer shell 3 is a transparent member obtained by injection molding a hard plastic, and a pair of outer shell elements 3F are adhered in a mochi-like manner to form a three-dimensional shape that wraps the body core 2. These pair of outer shell elements 3F adopt a symmetrical shape and each has functional parts of substantially the same shape. First, their peripheral edges are joined edges 30 that are joined to each other. The recess surrounded by this joined edge 30 constitutes the internal space of the outer shell 3 in a state where the pair of outer shell elements 3F are combined in a mochi - like manner.
[0025] Incidentally, the outer shell 3 closely wraps the body core 2 inside, and including the body core 2, the body main body 5 becomes an apparent solid. As a result, even if the outer shell 3 is configured to have a thickness dimension as thin as possible, the necessary strength as the fishing lure 1 can be obtained. For this reason, it is not necessary to provide internal reinforcing ribs made of resin or the like that cause a decrease in buoyancy, as is generally adopted in lures made of hard plastic.
[0026] Furthermore, the outer shell 3 is provided with eye holding parts 31. Specifically, as an example, it has a head eye holding part 31A, a belly eye holding part 31B, and a tail eye holding part 31C. The shape of each eye holding part 31 corresponds to the shape of the eye 11 to be attached. First, for each eye 11, the shape of its functional part 11f is generally annular and common, but the shape of the assembling part 11p is different.
[0027] Among these, the head eye 11A and the tail eye 11C have an assembling part 11p that is generally annular and has a shape that can be expressed as a gourd - like shape as a whole. For this reason, the eye receiving parts 31p in the head eye holding part 31A and the tail eye holding part 31C are formed as circular groove - like concave grooves according to their shapes. On the other hand, for the belly eye holding part 31B, since the shape of the assembling part 11p is so - called T - shaped, the eye receiving part 31p is formed as a T - shaped concave groove accordingly. Regarding this belly eye holding part 31B, the joined edge 30 is formed at a trapezoidal part with a meat buildup on the inner side in side view, and meat - removing holes 32 are formed at three locations as an example in this meat - buildup part. Furthermore, on the outer shell 3, a downward - sloping lip holding slit 33 is formed below its head.
[0028] And such individual components are assembled to form the fishing lure 1 of the present invention. Hereinafter, the procedure will be described. First, for the body core 2, it can be obtained, for example, by cutting a material such as paulownia wood with a processing device capable of precision machining such as an NC router according to a predetermined design specification.
[0029] On the other hand, for the outer shell 3, a thermoplastic resin is supplied to an injection molding machine equipped with a molding die according to the design specification and molded. And the body core 2 is decorated with a fish attracting pattern 22 or the like. In this embodiment, a seal - shaped decorative sheet with a pattern or the like printed thereon is pasted. Also, the eye 11, the lip 12, and the weight 13 are prepared separately.
[0030] After arranging such components, one outer shell element 3F is held by an assembly jig, and the body core 2 is fitted into its concave portion. Then, the other outer shell element 3F is placed over the body core 2 and combined in a monaka - fitting manner with the other outer shell element 3F that has already been installed. Of course, prior to the combination, the eye 11 and the weight 13 are arranged at predetermined positions, and an adhesive is provided on at least one joint edge 30 by stamping or the like. Then, the lip 12 is fitted into the lip holding slit 33 and fixed by adhesion.
[0031] The fishing lure 1 configured in this way has the body core 2 that is substantially in close contact with the inside of the outer shell 3, and the body core 2 functions to reinforce the outer shell 3 whose relatively thick dimension t is set thin. That is, when viewed as a whole, the body main body 5 appears to be a solid entity, and the physical properties of the body main body 5, such as the mass distribution and buoyancy distribution, are equivalent to those of a handmade wooden lure. Thus, the fishing lure 1 of the present invention can minimize the damage that occurs during use while maintaining the functions such as the buoyancy and surface decoration of the lure made of woody materials. The "substantially close contact state" indicates that even if each element is deformed due to changes in the environment such as temperature, a slight clearance is provided to allow this without the lure being damaged.
[0032] And for the specific thickness dimension t of the outer shell 3, for example, when the maximum dimension of the body width dimension w of the illustrated fishing lure 1 is 14 mm, it is about 0.06w (0.8 mm). That is, the thickness dimension t of the outer shell 3 is 1 / 10w or less. As a specific dimension that technically achieves an effect, it is about 0.5 mm to 1.5 mm, and preferably a thickness dimension of 0.6 to 0.8 mm is desirable. Regarding even larger fishing lures 1, the thickness dimension t of the outer shell 3 is configured while maintaining this dimension range.
[0033] In addition, the fishing lure 1 of the present invention can make the outer shape of the mass-produced product highly accurate and uniform by using the outer shell 3 as an industrial product obtained by injection molding hard plastic. Since the outer shell 3 is obtained by injection molding, the degree of freedom in design is high, and by preparing a plurality of molding dies, size expansion and series expansion can be easily performed. Furthermore, the fishing lure 1 of the present invention can easily and inexpensively produce a plurality of types rich in pattern variations and color variations suitable for different conditions such as weather and different target fish for fishing results, just by changing the fishing pattern 22.
