Description

Description Title of the invention: Method for manufacturing a fishing lure and fishing lure. Technical field of the invention

[0001] — The present invention relates to a method for manufacturing a fishing lure and Fishing lure. It applies, in particular, to lures of the swimming fish type. intended for fishing.

[0002] — The present invention relates to a hard fishing lure, in particular for fishing for trolling or so-called "casting" fishing practiced in lakes, rivers, or the sea, starting from the on the shore or by boat, using a spinning rod equipped with a reel, or for any another fishing technique requiring the use of a lure simulating the movements oscillating movements of the prey it imitates, during its movements in or on the water. Previous technique

[0003] The current world has only fueled growth and interest in activities of Simple pastimes like fishing. However, as with any pastime, practitioners re- seek perfection and performance, which often transforms leisure into a genuine physical activity.

[0004] …— The aesthetics of the lure are important to the fisherman. Also, the fisherman wears a focus attention on the eye of the fishing lure.

[0005] — On the market, there are two types of fishing lure eyes: paper eyes or glued plastic and painted eyes.

[0006] — In all cases, the addition of these eyes takes place at the end of production and represents a final stages.

[0007] Most plastic fishing lures are manufactured in the following way:

[0008] — - a) injecting a male and a female shell to form the body of a lure fishing; these shells may or may not be dyed throughout and may or may not contain overmolded parts.

[0009] — - b) insert internal elements such as, for example, a balancing ballast and a frame receiving the hooks.

[0010] - c) assemble by welding the two shells containing the inserts.

[0011] — - d) carry out finishing by painting, and / or removal of heat-shrink film and addition eyes.

[0012] — - e) apply a protective varnish to the finish; this is an essential step to ensure the longevity of the paint as well as its durability for the eyes.

[0013] — - f) attaching hooks;

[0014] - g) put in packaging. Due to the relatively limited production runs per color in the European market, only step a) is generally automated. Therefore, steps b) through g) require manual labor and represent a significant portion of the product's cost price. As a result, the majority of global production is located in Asia. The fishing lure is made of hard plastic and is a type of lure used in fishing to imitate the behavior and appearance of different prey, in order to attract the interest of fish. One of the goals of the present invention is to limit the number of steps. Furthermore, the use of paint or plastic eyes introduces plastic material that is polluting to the environment. In the context of environmental protection for a plastic lure used in the marine environment, these conventional solutions are therefore unacceptable. Presentation of the invention The present invention aims to remedy these drawbacks with a totally innovative approach. More specifically, the invention aims to provide a better technique for the environment. In particular, one objective of the invention is to provide such a technique as to reduce the number of manufacturing steps. These objectives, as well as others that will appear later, are achieved, in a first aspect, using a manufacturing process for a fishing lure, remarkable in that the process comprises the following successive steps: - a) inject a male hull and a female hull to form the body of a fishing lure; said male hull has barbs; said female hull has assembly holes corresponding to the size of the barbs of the male hull, the male hull and the female hull forming a fishing lure between a first end and a second end, the first end forming the head of the fishing lure having a through hole and the second end forming the rear of the lure; - b) insert into the male or female hull at least one of the following elements chosen from: a balancing weight which is positioned at the second end and at least one first ball positioned at the head of the lure in said hole through and forming the eye of the lure; . - €) assemble the male and female shells by welding; during assembly, each lug of the male shell fits into the assembly holes of the female shell. Thanks to these arrangements, the moment of inertia is increased, which creates a decoy. more stable when casting. You also get better casting accuracy and a greater range of motion when swimming the fishing lure. The moment of inertia, also called the second moment of area or quadratic moment, is a measure of the distribution of a body's mass around its axis of rotation. More precisely, it is the amount of force that must be applied to change the rotational speed of a body around that axis. The moment of inertia of a body is determined by its shape, mass, and mass distribution. The present fishing lure produced by this process has a greater moment of inertia than a fishing lure produced by the classic process described in the previous technical section. The invention is advantageously implemented according to the embodiments and variants set out below, which are to be considered individually or according to any technically feasible combination. In one embodiment, during step a) of injection, the male shell and the female shell are made of hard plastic material. Hard plastic is a type of plastic material that is known for its durability and resistance to breakage. Hard plastic is generally made from polymers such as ABS (acrylonitrile butadiene styrene), polylactic acid, polyethylene, polypropylene, polystyrene, and PVC (polyvinyl chloride). It is also often reinforced with strengthening agents such as fiberglass or carbon to improve its strength. Hard plastic can be manufactured in various ways, including injection molding, blow molding, and thermoforming. In one embodiment, during step a) of injection, the male shell and the female shell are made of biodegradable hard plastic material. It is possible to manufacture hard plastic from biodegradable materials, resulting in biodegradable hard plastic, which is a material that can be broken down by microorganisms in the environment. This means that instead of remaining in the environment for many years like traditional plastics, biodegradable hard plastic can decompose naturally and return to the environment as organic matter. There are several types of biodegradable materials that can be used to make hard plastic, such as corn and potato starches, wheat proteins, sugarcane and rice polysaccharides, palm and soy fatty acids, and raw materials from biomass. In one embodiment, during step a) of injection; the through hole is in part in the male shell and part in the female shell. In one embodiment, during step b), the male shell and the female shell have a second ball, the first ball and the second ball are adjacent and fit into each through hole of the male shell and the female shell. In one embodiment, during step c) of assembly, said welding is chemical or mechanical. In one embodiment, said process further comprises, after step c): - d) attach at least one frame with hooks to the fishing lure. In one embodiment, the first ball or the second ball is made of mineral material. For example, the ball(s) are made of glass, steel, tungsten, lead, zamak, copper… The use of one or more mineral beads makes it possible to offer a solution that does not cause residual plastic pollution or acute ecotoxicity in the marine environment. According to a second aspect, the present invention relates to a fishing lure according to the implementation of the method according to one of the preceding claims. The advantages, purposes and particular characteristics of this fishing lure being similar to those of the manufacturing process of a fishing lure which is the subject of the present invention, they are not recalled here. Brief description of the figures Other advantages, purposes and features of the present invention will become apparent from the following description, given for explanatory purposes and in no way as a limitation, with reference to the accompanying drawings, in which: -Fig.1 represents a perspective view of a fishing lure according to an object of the present invention; - [Fig.2] represents a front view of a fishing lure; - [Fig.3] represents a top view of a fishing lure; - [Fig.4] represents a front view of another example of a fishing lure; - [Fig.5] represents a view of a fishing lure in perspective of [Fig.4]. - [Fig.6] represents another view of a fishing lure in perspective of [Fig.4]. - [Fig.7] represents a perspective view of a fishing lure before the assembly stage; - Fig. 8 represents a perspective view of another fishing lure before the assembly stage. - [Fig.9] represents two views of a fishing lure made by the prior art process, it represents a front view and a top view; - Figure 10 shows two views of a fishing lure manufactured according to said process, It represents a front view and a top view; - [Fig.11] represents the appearance of a fishing lure from [Fig.9]; - [Fig.12] represents the appearance of a fishing lure from [Fig.10]; - [Fig.13] represents the setup for the fishing lure casting test; - [Fig.14] represents a fishing lure in perspective view with its fishing line when it is unstable; - [Fig.15] represents a fishing lure in perspective view with its fishing line when it is stable; - [Fig.16] represents a flowchart showing the steps in the manufacture of a lure. Description of the implementation methods Figure [Fig. 1] shows a perspective view of a fishing lure. This figure shows an elongated fishing lure extending from one end to the other. The first end forms the head of the lure, and the second end forms the tail. The body of the elongated lure is formed by two sections: a male section and a female section. In this diagram, you can see a hoop positioned at the first end and a second hoop positioned at the other end, that is, the second end at the rear of the fishing lure. Also visible is a bead 22, representing the eye of the fishing lure. You can also see gills on each side of the lure's head. Naturally, the invention described above is by way of example. It is understood that a person skilled in the art is capable of carrying out different embodiments of the invention without departing from its scope. Figure [Fig. 2] shows a front view of a fishing lure. Some elements are repeated from the previous figure. This figure shows a hoop, also known as a fixing ring, located at the bottom and roughly in the middle of the fishing lure. A 24 weight is also visible, positioned at the other end of the fishing lure. Figure [Fig. 3] shows a top view of a fishing lure. Some elements are taken from the previous figures. In this variation of the fishing lure, two 22mm beads are positioned adjacent to each other. The first 22mm bead and the second 22mm bead are each positioned in a hole through each of the two halves of the lure, representing each eye. Each 22mm bead is positioned in each of the two halves of the lure. To maintain balance, the two 22 balls touch in the middle of the lure. fishing. They touch at the longitudinal axis of the fishing lure. In this figure, it is also visible that the weight 24 is also positioned in the middle of the longitudinal axis of the fishing lure to maintain balance. Figure 4 shows a front view of another example of a fishing lure. In this figure, some elements are taken from previous figures. The rigging consisting of a split ring 25 and a hook 26 has been added. The rigging is positioned on this example on the hoop 21 at the bottom and middle of the fishing lure as well as at the second end of the fishing lure. Figures 5 and 6 show a perspective view of a fishing lure from [Fig.4]. In these figures, certain elements are taken from previous figures and allow for a better understanding of the different elements. Figure 7 shows a perspective view of a fishing lure before the assembly stage. In this figure, some elements are taken from previous figures. This figure shows two halves of the fishing lure before assembly. Visible are the 27 tabs that allow each half to be positioned relative to the other and that engage with corresponding holes in the female half. The 27 tabs are located on the male half. In this example, there is only one ball 22 positioned in the middle between the two shells and it will be visible through the hole through each shell. Figure 8 shows a perspective view of another fishing lure before the assembly stage. In this figure, some elements are taken from previous figures. Two balls 22 are visible which will be, after assembly, in each through hole of the male and female shells. In this variant, it is visible that the fishing lure has grooves to reinforce its internal structure. Fig. 9 shows two views of a fishing lure made by the prior art process; it represents a front view and a top view. Equivalent lure balancing is achieved by the lure density and the equivalent center of gravity positions G and thrust positions P. Fig. 10 shows two views of a fishing lure made according to said process; it shows a view of the face and a top view. In this figure, some elements are taken from the previous figure. Using 22 through-balls for the eyes increases the lure's moment of inertia along the (P, Z) axis. This higher moment of inertia directly results in the stabilization of the lure during the casting phases, thus increasing casting distances in the presence of wind. During the tests explained below, we noted an average increase in casting distances of 35% with tailwind, 55% with headwind and 5% with sidewind thanks to the fishing lure produced by the process. We also observe an increase in accuracy of around 10% and a 20% improvement in throw stability. Fig. 11 shows the appearance of a fishing lure from Fig. 9. Figure 12 shows the appearance of a fishing lure from Figure 10. This weight distribution also maximizes the lure's darting action during the swimming phase, reducing oscillation. The lure's inertia relative to the (P, Z) axis optimizes the return of energy imparted by the angler while limiting sensitivity to external disturbances. This maximizes the lure's effectiveness and makes it easier to use. Figure [Fig. 13] shows the diagram of the setup for the fishing lure casting test. To define a product's casting performance, we established a standardized testing protocol. It's important to note that this system is only for comparative purposes; casting distances and accuracy depend on the caster, equipment (rod, reel, line), and weather conditions. Weather conditions: wind less than 6 knots and no gusts. Casters: suitable for all anglers, from beginners to experienced. For beginners, a learning phase is carried out before measurements to avoid excessive standard deviation. Fishing equipment: all tests in the same series are done with the same rod, the same reel and the same lines, regardless of the casting device. Measurement system: a decameter is unrolled in a straight line on a stable, flat surface. It allows the length L to be measured. A decameter also allows the width | to be measured, enabling the angle α to be calculated. Configuration: we call the test configuration the triptych: orientation of the launcher in relation to the wind, set of fishing equipment, product at the end of the line. Protocol: A minimum of two throwers participate in the test. Taking turns, each thrower casts the lure with the aim of going as far as possible and getting as close as possible to the measuring tape drawn on the ground. One of the inactive throwers then measures the Let lengths. It is important to make the casts consecutively to ensure that the weather conditions do not change significantly, which would invalidate the test. A minimum of seven throws per thrower and per configuration must be carried out in order to have a sufficiently representative sample. We define two launch performance indicators: - The throwing distance L; - The throwing accuracy represented by a. For products equivalent in terms of mass and volume (density), the greater the distance L and the lower the angle α, the better the throwing performance. Average values ​​and standard deviations are compared by configuration and by launcher, with product performance only comparable for the same launcher. However, to verify the generality of launching performance, trends can be compared between different launchers. Examples [Table 1] Launcher | Products Average L Average to pe [Product No. 1 56m 15° NE Product No. 2 64m 4 pe Product No. 1 32m 2 No. 2 Product No. 2 41m 4e The results in the table above indicate that Launcher No. 1 launches Product No. 2 14% further than Product No. 1 but with 2.6 times less accuracy. Launcher #2 launches Product #2 28% further but with 1.3 times less accuracy. We can therefore conclude that, in general, Product #2 is launched further (on average +21%) but with less accuracy (on average half as much) than Product #1. Thus, even if the launchers' performances are unequal, this procedure allows us to estimate the overall launching performance of a product. Figure [Fig. 14] shows a fishing lure in perspective view with its fishing line 28 when it is unstable. This figure incorporates some elements described in the previous figures. Figure 15 shows a fishing lure in perspective view with its fishing line 28 when it is stable. This figure incorporates some elements described in the preceding figures. During the study described above, we measured a third indicator of casting performance: stability. If, during certain casts, the lure starts straight and maintains a straight trajectory, then we classify the cast as stable. On the contrary, if the lure does not describe a straight trajectory but has random movements, then the cast is considered unstable ([Fig.14]). Figure 16 shows a flowchart outlining the steps involved in making a lure. Step 101 corresponds to step a). It involves injecting a male shell and a shell female to form the body of a fishing lure. Step 102 corresponds to step b). It involves inserting a balancing weight 24 and one or two balls from the male and female shells into the male or female shell. In this step, in one variation, an arch is added to allow the line and hooks to be attached. Step 103 corresponds to step c). It involves assembling the male and female shells by welding. In another step not shown, at least one hook and the fishing line are fixed either directly to the hoop or with a split ring for the hook, which constitutes the frame. The frame of a fishing lure is the part of the lure that is attached to the fishing line. It can be made of various materials, such as steel, and is designed to be strong and durable to withstand the movements and forces exerted by fish during fishing. The frame can be shaped like a hoop, hook, barb, or metal rod, and is usually attached to the lure with some kind of fastening system, such as a loop or clip. The frame plays a crucial role in the lure's effectiveness, as it securely attaches the lure to the line and makes it move in a way that attracts fish. Thus, compared to the manufacture of a conventional hard plastic lure, the production of a lure using this process is only 3 steps. Eliminating certain steps requiring skilled labor and representing the largest proportion of the cost makes it possible to relocate the production of a hard plastic lure of the same quality. It is emphasized that all features, as they are apparent to a person skilled in the art from the present description, drawings and attached claims, even if in practice they have only been described in relation to other specific features, both individually and in any combinations, may be combined with other features or groups of features disclosed herein, provided that this has not been expressly excluded or that technical circumstances render such combinations impossible or meaningless.
