Description

The present invention relates to lures that are used for various types of fishing, such as bass fishing.

When targeting large fish known as fish eaters, which mainly prey on small fish, lures with a long, thin, rod-like body with rounded ends that mimic the shape of a small fish, as shown in Patent Document 1, are sometimes used. In such lures, hooks are attached to the part of the body that corresponds to the center of the ventral side of the fish and to the part that corresponds to the tail, for example.

In addition, lures with bodies that have a flat cross-sectional shape with a biased aspect ratio are beginning to be used in order to amplify the vibrations and sounds generated when the lure is moved and encourage target fish to eat it.

Specific examples include fish such as catfish whose body width is greater than their body height, and frogs. In such cases, the hook is attached to the flat ventral side, which is the underside on the water surface or underwater. In addition, the body may be modeled after various fish whose body height is greater than their body width, and the hook may be attached to the flat side.

By the way, when you cast a lure, it may land in the water with the side of the body where the hook is attached facing up. When this happens, the hook will not get caught properly on fish that bite from underneath the lure.

However, it can be difficult to change the orientation of a lure on the surface or underwater by operating the rod or reel so that the hook points downward. In particular, in the case of lures with flat bodies such as those mentioned above, it is difficult to return the hook, which is on the upper side of the body, to the lower side.

The present invention was made in consideration of the above-mentioned problems, and aims to provide a lure that can change to a final intended position, such as a position where the hook is positioned on the bottom, regardless of the position it is in when it hits the water.

That is, the lure of the present invention is characterized by having a body on which a hook is attached, and a position change mechanism that, when the hook is on the upper side of the body when the lure hits the water, naturally changes the position of the body so that the hook is positioned on the lower side of the body.

With this type of lure, if the hook is facing upward on the body when it hits the water, the action of the position change mechanism will allow the hook to be automatically positioned under the body without the need to operate the rod or reel. This means that the hook can always be effectively used on the target fish without the need to redo the cast of the lure. Furthermore, even if the hook is not naturally positioned under the body, the action of the position change mechanism will make it easier to position the hook under the body when the rod or reel is operated.

In order for the posture change mechanism to naturally change the posture of the body so that the hook is under the body without the need for rod or reel operation, and with a simple structure that does not require any special power, the posture change mechanism needs to have a weight provided within the body and be configured to rotate the body by the movement of the weight due to gravity after the lure hits the water.

In order for the weight to act to generate a rotational force that rotates the body when the hook is above the body, and to stabilize the posture of the body when the hook is below the body, the posture change mechanism needs to be provided inside the body and further include a guide structure that guides the movement of the weight, and the guide structure needs to be configured to guide the movement of the weight between a position where a rotational force that rotates the body is generated and a stable position where the posture of the body is maintained with the hook positioned below the body. Furthermore, since such a posture change mechanism is provided inside the body, a high degree of freedom in the appearance and shape of the body can be maintained.

When the hook is on the underside of the body, in order for the weight to be naturally positioned by gravity in a position within the body that stabilizes its position, the weight should be spherical, and the guide structure should include a curved rail that is provided so as to be convex on the underside of the body when the hook is on the upper side of the body. In this way, the weight rolls on the curved rail due to gravity, and ultimately oscillates at or near the apex of the curved rail, stabilizing the position of the body with the hook on the underside of the body.

To make it difficult for the weight to move in the direction in which the curved rail extends at or near the apex of the curved rail and further increase the stability of the body's posture, the guide structure may be formed to protrude from or near the apex of the curved rail in the convex direction of the curved rail, and may further include a pocket in which the weight is housed so that it can move only between the curved rail and the guide structure.

A more specific embodiment of the posture change mechanism is one in which the rotational force generation position is set at the end of the curved rail, and the stable position is set at or near the apex of the curved rail, or in the pocket.

For example, when a lure is constructed to imitate a flattened fish body whose height is greater than its width, in order to have the hook naturally positioned under the body after landing on water, the body should be shaped like a fish, the hook should be provided on the side of the body, and the X-axis should be set along the overall length connecting the tail and head of the body, the Y-axis should be set along the body height connecting the back and ventral sides of the body, and the Z-axis should be set along the body width connecting a pair of side sections of the body. The curved rail should be curved so as to be convex in the Z-axis direction and extend along the Y-axis direction. The shape of the body is not limited to a fish, and may be, for example, a frog or an inanimate object such as a spoon. If the lure has a flattened body like this, a similar configuration can be used to make it easier for the lure to take a desired posture after landing on water.

For example, when constructing a wide flat type lure that imitates a fish or frog with a flat body whose width is greater than its height, in order to have the hook naturally positioned on the underside of the body after landing on water, the body should imitate the shape of a fish or frog, the hook should be provided on the ventral side of the body, and when the X-axis is set along the overall length connecting the tail and head of the body, the Y-axis is set along the body width direction connecting a pair of side parts of the body, and the Y-axis is set along the body height direction connecting the back and ventral sides of the body, the curved rail should be curved so as to be convex in the Z-axis direction and extend along the Y-axis direction.

A lure that is equipped with a body on which a hook is attached, and a posture change mechanism that changes the posture of the body naturally to the predetermined posture when the body is in a posture different from the predetermined posture when the lure hits the water, and that is characterized in that the posture change mechanism is equipped with a curved rail that is provided so as to be convex on the underside of the body when the body is in the predetermined posture, and a weight that rolls on the curved rail, makes it possible to naturally change the body to the predetermined posture by the movement of the weight due to gravity, even if the body is facing a posture different from the predetermined posture when the lure hits the water.

In this way, with a lure according to the present invention, even if the hook is positioned on the upper side of the body when it hits the water, the hook will naturally be positioned on the lower side of the body, so that the hook can always be effective on the target fish, even if the body shape is such that it is difficult to change its position by operating the rod or reel.

FIG.

A lure 100 according to one embodiment of the present invention will be described with reference to Figures 1 to 4.

<Configuration of the lure 100>
As shown in Fig. 1, the lure 100 of this embodiment is used for lure fishing and has a flat and wide body 1 that imitates the shape of a small fish. Target fish include fish eaters such as black bass. In the following explanation, the X-axis set along the overall length connecting the tail and head of the body 1, the Y-axis set along the body height direction connecting the back side and the ventral side of the body 1, and the Z-axis set along the body width direction connecting a pair of side parts of the body 1 will also be used.

The body 1 is made of, for example, resin or wood, and is flat with a body height greater than its width, and is used to allow the fish to move sideways on the water surface or underwater. For this reason, hooks F are attached to hook eyes FI provided on one of the flat side surfaces of the body 1 (the area with the eyes, gills, lateral line, etc.). In other words, hooks F are provided only on one side surface of the body 1, and not on the other side surface. For this reason, in order to ensure that hooks F always act effectively on the target fish, a posture change mechanism 2 is provided inside the body 1, as shown in Figures 2 to 4, which positions hooks F on the underside of the body 1 after the body 1 hits the water.

To describe the body 1 in more detail, as shown in Figure 1, the body 1 is composed of four parts. The body 1 comprises a front portion 11 that imitates a part of the front side of the head and body of a fish and has a line eye LI on the jaw portion, a central portion 12 that imitates a part of the rear side of the body of a fish, a rear portion 13 that imitates the body side of the tail of a fish, and a tail fin portion 14 that imitates the tail fin of a fish. The front portion 11 and the central portion 12, and the central portion 12 and the rear portion 13 are supported rotatably around the Y axis, and the rear portion 13 and the tail fin portion 14 are supported rotatably around the Z axis. Note that the axes are omitted in Figure 1.

Next, the posture change mechanism 2 will be described in detail with reference to Figures 2 to 4.

When the hook F is positioned on the upper side of the body 1 when the lure hits the water, the attitude change mechanism 2 naturally changes the attitude of the body 1 so that the hook F is on the lower side of the body 1. More specifically, the attitude change mechanism 2 rotates the body 1 by gravity, by changing the position of a weight 21 that is movably provided inside the body 1, so that the hook F is on the lower side of the body 1 on or underwater. In addition, after the hook F is positioned on the lower side of the body 1, the attitude change mechanism 2 stabilizes it in that state.

That is, the posture change mechanism 2 includes a spherical weight 21 and a guide structure 22 that guides the movement of the weight 21.

The guide structure 22 guides the movement of the weight 21 between a rotational force generating position P1 that rotates the body 1 and a stable position P2 that maintains the posture of the body 1 with the hook F positioned below the body 1. In this embodiment, as shown in Figures 2 to 4, the curved rail 2R extends along the Y-axis (body height direction) and is formed to be convex toward the hook F side in the Z-axis (body width direction), and is provided with a roughly bow-shaped curved rail 2R, and a roughly cylindrical pocket 2P that protrudes from the apex of the curved rail 2R or its vicinity in the convex direction of the curved rail 2R and accommodates the weight 21. The widths of the curved rail 2R in the X-axis and Z-axis directions and the diameter of the pocket 2P are approximately the same as the diameter of the weight 21. In other words, the curved rail 2R is composed of a pair of bow-shaped curved surfaces spaced apart in the Z-axis direction and a pair of side walls spaced apart in the X-axis direction.

In this embodiment, each end point in the Y-axis direction of the curved rail 2R is set as a rotational force generating position P1, and a stable position P2 is set in the pocket 2P.

In addition, when the hook F is on the underside of the body 1, the weight 21 is completely contained within the pocket 2P, which is the stable position P2, and is configured so that the weight 21 does not fly out from the pocket 2P to the curved rail 2R when the body 1 swings within a predetermined range. Furthermore, when the hook F is on the upper side of the body 1, the weight 21 falls from the pocket 2P to the curved rail 2R under its own weight, and finally rolls under its own weight along the curved surface of the curved rail 2R to one of the end points, which is the rotational force generation position P1, which is below the pocket 2P.

<Movement of the lure 100>
In the lure 100 thus constructed, the operation of the lure 100 when the hook F is positioned on the upper side of the body 1 upon landing on water will be described with reference to FIG.

If the hook F is positioned on the upper side of the body 1 when the lure hits the water, the guide structure 22 provided inside the body 1 will be in a state where the pocket 2P is on the upper side and the curved rail 2R is also convex on the upper side, as shown in Figure 4(a). Therefore, the weight 21 rolls along the curved surface of the curved rail 2R, and eventually reaches one of the end points of the curved rail 2R, which is the rotational force generation position P1.

Then, as shown in FIG. 4(b), the weight of the weight 21 is biased toward either the ventral side or the dorsal side of the body 1, and the body 1 rotates around the X-axis (rolling occurs in the body 1).

Furthermore, as shown in FIG. 4(c), when the ventral or dorsal side of the body 1 reaches its lowest point due to the weight 21 at the end point of the curved rail 2R, the weight of the hook F causes the body 1 to tilt further so that the hook F is on the lower side. In other words, the convex direction of the curved rail 2R and the pocket 2P also face downward.

When the hook F is placed on the underside of the body 1, or while it is being placed, the weight 21 moves toward the center along the curved rail 2R due to gravity, and is finally stored in the pocket 2P as shown in FIG. 4(d). When the weight 21 is stored in the pocket 2P, it will not jump out onto the curved rail 2R even if the body 1 sways slightly. Also, even if the weight 21 jumps out onto the curved rail 2R from the pocket 2P, it will return to the center along the curved rail 2R as long as the hook F is on the underside of the body 1. In other words, since a stable point of the weight 21 is formed with the pocket 2P as the center, the weight 21 also functions as a balancer that maintains its posture when the hook F is placed on the underside of the body 1.

<Effects of Lure 100>
Thus, with the lure 100 according to this embodiment, the posture of the body 1 is maintained so that the hook F is on the lower side, simply by the movement of the weight 21 due to the gravity acting on the weight 21, without the need to operate the rod or reel. In other words, even if the hook F is on the upper side of the body 1 when the lure 100 is cast and hits the water, the hook F is naturally positioned on the lower side of the body 1, and this state is stably maintained.

Therefore, even if the lure has a flat and wide body 1, the hook F can always be maintained on the underside of the body 1, where it is effective against the target fish. In addition, because the lure is formed as a flat and wide body 1, the waves and sounds generated when the lure 100 is moved can be increased to encourage the target fish to eat it. While enjoying the characteristics of the lure 100 due to its flat and wide shape, the hook F can always be positioned on the underside of the body 1 by the posture change mechanism 2, making it easier to use as a lure than conventional lures.

Other embodiments will be described.

In the above embodiment, the shape of the body imitates a fish whose height is greater than its width, but it may imitate a fish such as a catfish whose width is greater than its height. The body is not limited to imitating a fish, and may imitate various creatures such as a frog. In the case of a flat wide body imitating a creature whose width is greater than its height, a hook is provided in the center of the ventral side, and the X axis is set along the overall length connecting the tail and head of the body, the Y axis is set along the body width direction connecting a pair of side parts of the body, and the Y axis is set along the body height direction connecting the back side and ventral side of the body. In this case, the curved rail is curved so as to be convex toward the hook side in the Z axis direction and extends along the Y axis direction. The body may be not only a living thing such as a fish or a frog, but also a worm, or an inanimate object such as a spoon.

In addition, the shape of the body is not limited to a flat wide shape, but may be various shapes such as a pencil type. In other words, regardless of the shape of the body, the hook can be configured to be positioned on the underside of the body by the posture change mechanism.

The body configuration shown in the above embodiment is merely an example and may include various forms. For example, instead of being made up of four parts, the body may be formed of one part, or may be made up of two, three, five or more parts. Also, the line eye may not be provided on the part of the body that corresponds to the jaw, but may be provided on another part. The position of the hook eye may also be set appropriately.

Another embodiment of the present invention is one in which the guide structure does not have a pocket and is composed only of a curved rail. Even in such a case, the posture of the body can be stabilized so that, for example, the hook is on the bottom side by swinging the weight near the apex of the curved rail. Furthermore, the present invention is not limited to a body posture that changes naturally so that the hook is on the bottom side. In other words, the lure may be configured so that it naturally assumes a predetermined posture assumed on the water surface or underwater. Specifically, such a lure may include a body on which a hook is provided, and a posture change mechanism that naturally changes the posture of the body so that the body assumes the predetermined posture when the body is in a posture different from the predetermined posture when it lands on the water, and the posture change mechanism may include a curved rail that is provided so as to be convex on the underside of the body when the body is in the predetermined posture, and a weight that rolls on the curved rail.

The posture change mechanism is not limited to that shown in the above embodiment. For example, the weight may be supported by a spring or the like, and the position of the weight may be changed depending on the position of the hook body, so that if the hook is on the upper side of the body when the hook hits the water, the hook will naturally be positioned on the lower side of the body. Also, if the movement of the weight does not require the weight to roll, the shape of the weight is not limited to a spherical shape.

The number and shape of the hooks may be set appropriately according to the purpose and the target fish. The target fish is not limited to black bass, but may be sea bass or other large fish. Furthermore, the lure of the present invention is not limited to targeting only large fish, and the posture change mechanism of the present invention may be applied to egi, etc., which are used to target octopus, squid, etc.

In addition, various modifications of the embodiments and combinations of parts of each embodiment may be made without going against the spirit of the present invention.
