JP7527014B2 - Sinking minnow type lure - Google Patents

Description

This invention relates to sinking minnow-type fishing lures.

Conventionally, mainly minnow-type lures have artificial eyes in the lure body that resembles a fish, and are known from Patent Documents 1 and 2, etc.

On the other hand, sinking lures are often made of lightweight materials such as thin plates of stainless steel or aluminum or plastic plates or molded materials in the hopes of creating a variety of different behaviors in the water, but a weight is attached to the lure body so that it can be submerged in the water and move in a natural position.

The types of lures that use thin steel or light metal plates for the main body include those that use lead as a weight welded from the area near the eye to the chest (tentatively named "Type A"); those that use plastic material for the main body include those that have a metal weight ball inside and are molded with plastic to form a sphere that is molded as one piece with the main body of the lure (tentatively named "Type B"); and those that have a plastic sphere with a weight inserted into eye holes drilled in the same position in two plastic plates, which are then sandwiched together and fixed by gluing or thermocompression (tentatively named "Type C").

Utility Model Registration No. 3225690 JP 2005-192512 A

The lure in Patent Document 1 has an axis-shaped attachment member 52 inserted on both sides at the eye position of the lure body, and eye parts 51 attached to the end faces, which means there are many parts and manufacturing processes, making it expensive, and the eye parts 51 tend to peel off during use and have poor durability.

The lure in Patent Document 2 has three overlapping lure plates that are connected and fixed at the front and rear ends with screws or pins, and the heads of the cap nuts or bolts or the heads of the locking pins used for the screws are designed to resemble fish eyes, but this example also requires a large number of parts for the screws and pins, and there are problems with high costs and durability due to the number of parts processing and assembly steps (see Figures 2 and 8 of the same document).

Furthermore, the lures in References 1 and 2 do not take into consideration sinking in water or natural movements, and do not include weights to maintain posture balance.

The weights of the A to C types of lures mentioned above require lead soldered to a metal lure plate, and the eyeball, a metal ball molded in resin, is remolded or clamped to the lure body and then glued to a plate, which requires many manufacturing and assembly steps, as well as labor and cost issues such as the need for molds and spot welding. In addition, the eyeball of the C type tends to come off easily during use and is poorly durable.

The lure of the present invention for solving the above problems is, firstly, a sinking minnow-type lure having one or more weight holes drilled into a lure plate shaped like an artificial bait when viewed from the side, and weight parts inserted and fixed into the weight holes so as to protrude from both sides of the lure plate, the weight parts being inserted into the lure plate and made of metal members which are attached and fixed to the lure plate by crimping , a plurality of fishing line attachment holes are drilled into the lure plate, separated into front and rear, for attaching a fishing line, making it possible to adjust the front-to-rear balance of the lure by selecting which fishing line attachment hole to attach the fishing line to, at least one of the weight parts is made to look like the eye of the artificial bait, the weight part is an axis- or plate-like member or a spherical member whose axis intersects with the lure plate, and both ends protrude in a mountain shape from both sides of the lure plate .

Secondly , the lure plate is characterized by being made of a metal plate.

Thirdly , the weight part has a protruding end whose outer circumferential surface is partially formed into a ring-shaped spherical surface or whose entire surface is formed into a semispherical surface.

The present invention, configured as described above, requires fewer parts and is easy to manufacture, reducing costs. In addition, the fastening force between the lure plate and the weight part is strong due to the crimping process, improving the durability of the lure. The weight part also serves as the eye part, eliminating the need for a separate eye part.

FIG.

1 to 3 are drawings sequentially showing the components of the lure of the present invention and the manufacturing process of the lure, and in this example, the lure is composed of a lure plate 1 made of a stainless steel thin plate shaped to resemble a small fish when viewed from the side, and a weight part 3 made of a cylindrical or circular plate-like shaft member that fits and passes through a circular weight hole 2 drilled on the front end (head) side of the lure plate 1. This weight part 3 also serves as an artificial eye of a small fish, as will be described later.

The example shown is a sinking minnow type lure mainly for mountain streams, with the lure plate 1 being a plate with a thickness of 0.5 mm, a total length of 31 mm, and a width at the bottom of the length of 11 mm, the inner diameter of the sinker hole 2 being about 6 mm, and the sinker part 3 being machined to an outer diameter of 6 mm and a length of 9 mm. The lure plate 1 is made of thin stainless steel plate in consideration of light reflection in water, rust prevention, and durability, but other materials such as iron, copper, low-density metals such as aluminum, and alloys of these can be selected depending on the conditions of use, and the sinker part 3 is preferably a metal or other material with high plasticity suitable for crimping processing described later, and if the sinker part 3 also serves as an eye due to the nature of the artificial bait, it is preferable that the light reflectivity of the lure plate 1 is the opposite.

Figures 2 (A) and (B) show the state where the weight part 3 is inserted left and right into the weight hole 2 of the lure plate 1 and fixed at the middle position. This fixing is performed through a process where the weight part 3 is inserted to the middle position and the outer diameter of the weight part 3 is enlarged and deformed (crimped) by applying pressure or impact with a press or the like from both ends protruding from the plate surface.

By attaching and fixing the weight part 3, the shaft-shaped member can look like an eye of a small fish or the like, so it is possible to complete and use it as a lure in this state. However, in this example, as shown in Figures 3(A) and (B), the left and right protruding ends of the weight part 3 are subjected to a crimping process in which pressure or impact is applied by pressing or the like using a die (not shown) with a hemispherical recess, for example, to form the whole into a hemispherical shape or a part of the peripheral surface on the base end side of the protruding part into a ring-shaped spherical shape, thereby increasing the imitation as an eye and the ease with which the target fish will bite. This crimping shape does not necessarily have to be spherical, as long as it is mountain-shaped and easy for the target fish to recognize it as a small fish.

The sinker part 3 also doubles as an eyeball, so by changing its left-right length and diameter, the sinking ability, balance, and water resistance in water can be adjusted. When using a metal with a higher specific gravity, it is also possible to use a small circular plate with a left-right length (or plate thickness). Depending on the fishing conditions, it is also possible to use a plate with a thickness equal to or close to that of the lure plate 1. In this case, it is not necessarily necessary to crimp the end face of the sinker part 3 into a mountain shape.

In this way, by stocking multiple types of weight parts 3 with different dimensions and materials, it is possible to manufacture different lures depending on the purpose and conditions of use.

Furthermore, the weight part 3 is not limited to the shaft-shaped or circular plate-type with a circular cross section as described above, but can be any shape, such as a polygonal cross section, a sphere, or an ellipse, depending on the type of lure to be targeted. In all these cases, the point of fixing by crimping or the processing of rounding the protruding end by crimping as necessary are common.

Before crimping and rounding the protruding end of the weight part 3 as described above, the diameter of the part is expanded by pressurization to attach it to the lure plate 1. This has the effect of preventing cracks and deformations from occurring on the outer circumference of the weight hole 2 on the lure plate 1 side during the crimping process to round the head of the protruding end.

At the rear end of the lure plate 1, which is shaped like a small fish, there is a hook attachment hole 4 for attaching a fishing hook (not shown), and at the top rear of the sinker hole 2, there are multiple fishing line attachment holes 6 for attaching a fishing line (line or leader). Depending on which fishing line attachment hole 6 the fishing line is attached to, the front-to-rear balance of the lure can be adjusted according to the fishing spot conditions and other conditions. The fishing line or fishing hook is attached using a jump ring or other connector.

According to the present invention as described above, the weight part 3, which also serves as the eyeball member, is fixed to the lure plate 1 by crimping, which provides strong adhesion and excellent durability, and also reduces costs due to the small number of parts and easy processing. In addition, by selecting from multiple lengths of weight parts with the same diameter, it is possible to adjust the weight of the weight and the balance with the lure plate, and the rounding of the protruding end of the shaft-shaped member can always be performed using the same mold.

In the above embodiment, a small lure plate (e.g., lure plate length of about 20 to 50 mm) is assumed for mountain stream fishing, but the size can be selected to be about 200 mm in total length for sea fishing. Depending on the purpose and size, the thickness and material of the lure plate, the diameter and length of the shaft-shaped member, and the size and material of the sinker parts can be selected as desired. Similarly, the drilling position and number of sinker holes can be adjusted. For example, in the case of a relatively large lure plate, multiple sinker parts can be distributed and positioned front and back depending on the target fish and other conditions, and the vertical position of the installation can also be adjusted.
