The electromagnetic lure driver comprises a water-tight sealed lure body (102) having a lure body longitudinal axis (Y) and an electromagnetic oscillation driver, wherein a first pole axis (P1) of an electromagnet (300) extends substantially parallel to the lure body longitudinal axis (Y) and a second pole axis (P2) of a permanent magnet (313) is arranged at a defined angle to the first pole axis (P1).

Description

TECHNICAL FIELD

[0001] The invention relates to an electromagnetic fish bait drive according to the upper concept of independent claims 1 and 7, and to a method according to claim 17. BACKGROUND

[0002] A large number of artificial fish baits are used instead of live fish baits, which are prohibited. In addition, dead natural fish baits are moved using electromagnetic actuators to imitate the movement of a live prey. In order to catch predatory fish, it is crucial to provide artificial fish baits or dead natural fish baits that move as naturally as possible.

[0003] The prior art German patent application DE 10 2018 117 801 A1 discloses an electromagnetic oscillating drive with a permanent magnet, which is adapted to move the artificial fish bait on the body side and on the tail side, relative to the self-movable artificial fish bait. The direction of the electromagnetic body coil is such that the pole axis of its magnetic field is transverse to the longitudinal axis of the self-movable artificial fish bait, and the movable permanent magnet can be moved transversely to the longitudinal axis of the self-movable artificial fish bait due to the magnetic force exerted by the magnetic field of the electromagnet.

[0004] The disclosed arrangement of the electromagnetic components, in particular the electromagnetic coil, requires a sufficiently large movement space to accommodate the field coil transverse to the longitudinal axis of the self-movable artificial fish bait, which requires a sufficiently large body housing. A miniaturized embodiment, which is required for a smaller body housing to accommodate smaller fish baits, for example artificial or natural fish baits, reduces the available movement torque and the maximum possible tail fin deflection.

[0005] US 2017 / 0181 417 A1 discloses a motorized fish bait having one or more rotary devices on a drive unit. The drive unit moves the tail and / or head of the fish bait and attracts predatory fish. This movement is generally understood to mean that the head and tail of the fish bait are moved from one side to the other, imitating a swimming fish, or, alternatively, imitating a trapped fish. The drive unit is powered by a power source to provide electrical power. A controller connected to the power source has at least one electromagnetic actuator motor, or an unspecified electromagnetic coil motor connected to the controller, for converting electrical energy into mechanical energy, and an articulated hinge coupled to the electromagnetic actuator motor or the electromagnetic coil motor for converting the mechanical energy into movement of the fish bait. The disadvantage of this fish bait is that the electromagnetic actuator motor and the articulated hinge require a large amount of energy to be absorbed, and that this device produces unnatural twisting and mechanical flipping noises during movement, which can be received by the sensitive lateral line organs of the predatory fish and which do not dare to approach. The electromagnetic coil motor is conceptually referred to as an "electric-magnetic coil motor" and is adapted to implement a known electric motor comprising a rotating electromagnetic coil.

[0006] WO 2016 187 007 A1 describes a motion generating device having a propeller operably connected to a deflectable structure that is fabricated and arranged to be inserted into the mouth of a fishing lure. The propeller and deflectable structure are adapted to deflect a portion of the fishing lure by at least 5 degrees. A device is described comprising a housing having a movable portion and a driver to move the movable portion relative to the housing. The housing, movable portion, and propeller are sized and shaped to fit at least partially within a fishing lure. Further, the propeller and movable portion, when positioned in the fishing lure, move a first portion of the fishing lure relative to a second portion of the fishing lure.

[0007] The propeller generates a continuous or intermittent rotational motion to drive a mechanical linkage element or an eccentric drive element and generates a linear motion by a piston. In this regard, the propeller can include one or more of a motor, an electroactive polymer, a piezoelectric material, a hydraulic motor, a gear component, a piston, unspecified electromagnetic coils and magnetic materials, a spring, an eccentric rotating pin, a slot, a yoke. While electromagnetic coils and magnetic materials are mentioned as part of the propulsion system, only the use of these components in a motor or in an electromagnetic gear motor is disclosed to the skilled person. The propeller includes a motor, in particular an electromagnetic gear motor, which is connected with an eccentric pin or ball that rotates around an axis to travel on a yoke or through a slot for generating an upward motion.

[0008] The disadvantage is that electromagnetic motors and eccentric mechanisms require a lot of space and energy and that such a device generates unnatural turning and mechanical flipping noises during the motion, which can be received by the sensitive lateral line organs of predatory fish and scare them away.

[0009] WO 2014 194 397 A1 describes a fishing lure adapted to move spontaneously in water, mimicking the natural motion of a live prey fish. The fishing lure includes a waterproof fishing lure body having a motor and a swing arm assembly connected to the fishing lure body by a tail shaft, the tail shaft being driven by the motor to swing the swing arm assembly. The described propeller includes a coil positioned relative to a fixed magnet, wherein the coil oscillates back and forth in response to a pole interaction between the coil and the magnet, which alternately generates in the coil as defined by a controller.

[0010] One disadvantage of this is that the coil oscillating back and forth in the bait body above the stationary permanent magnet mechanically hits the holder at its end positions and produces switching noises, which are received by the sensitive lateral line organs of predatory fish and scare them away. Furthermore, the electrical connection between the moving coil and the controller requires a moving feed line, which is mechanically stressed due to the permanent mechanical movement of the coil and thus is another source of noise and also susceptible to failure due to material fatigue. The lateral coil requires enough space for moving between the side walls of the bait body or requires a correspondingly miniaturized embodiment to be accommodated in a smaller bait. This reduces the available moment of movement and the maximum possible tail fin deflection.

[0011] It is therefore an object of the present invention to provide an efficient electromagnetic bait drive which does not have the disadvantages of the prior art, which can be integrated in a space-saving and cost-effective manner even in small artificial or dead baits, which allows the propeller to move the artificial or dead bait as efficiently as possible with low energy demand, which imitates the natural movement process of a healthy or sick prey, thus capturing predatory fish, which can be controlled or adjusted in a defined manner by the angler, which does not emit unnatural vibrations, and which allows the use of conventional rod mounting. It is a further object of the present invention to provide a method of controlling an electromagnetic bait drive. SUMMARY

[0012] The above problems are solved by the electromagnetic bait drive according to the features of independent claim 1 and independent claim 7, the system according to claim 14 and the method according to method claim 17. Preferred configurations and embodiments of the present invention are subject to the dependent claims.

[0013] For the purposes of the present invention, a bait is an artificial bait which is as close as possible to a natural replica of a natural prey, preferably a fish, or a dead natural prey in the form of a dead natural bait, preferably a dead fish. The natural prey can also include other animals such as frogs, toads or mice, or other prey or insects.

[0014] By movement driven by the electromagnetic bait drive in the sense of the present invention, it is understood that the body and / or tail of the artificial or dead natural bait is moved from side to side along its longitudinal axis to imitate a swimming or dying fish, or to imitate other trapped natural prey. Advantageously, the movement of the electromagnetic bait drive can additionally produce a force effect which pushes the bait forward.

[0015] The electromagnetic bait drive comprises a bait body and an electromagnetic oscillation drive.

[0016] For the purposes of the present invention, the fish bait body comprises a watertight sealable body that can be sunk into water, which can be integrated into an artificial fish bait or a dead natural fish bait. The fish bait body has a front end that can be integrated into an artificial fish bait or a dead natural fish bait in a head-oriented manner. The fish bait body further comprises a side that forms a side wall of the fish bait body. Preferably, the fish bait body is cylindrical and has a circular or oval tubular cross-sectional profile. However, other cross-sectional profiles are also applicable, such as a square, rectangular, polygonal, kidney-shaped tubular cross-section or a cross-section with any circumferential tubular closed profile. Advantageously, as an alternative to a cross-section that is constant along the longitudinal axis Y of the fish bait body, the fish bait body has a cross-section that varies along the longitudinal axis Y of the fish bait body, for example, an elliptical, tear-drop or cigar-shaped profile, thereby replicating and supporting the streamlined shape of the artificial fish bait or the dead natural fish bait. The fish bait body has a rear end that can be integrated into an artificial fish bait or a dead natural fish bait in a tail-oriented manner. The fish bait body can be integrated in an elongated manner in an artificial fish bait or a dead natural fish bait. The aspect ratio between the length of the fish bait body and the maximum width of the fish bait body is greater than 1, in particular greater than 2, preferably greater than 5. The longitudinal axis Y of the fish bait body extends centrally through the front end and the rear end of the fish bait body, respectively, in the fish bait body.

[0017] For the purposes of the present application, the body shell of the fish bait comprises the coated body of the artificial fish bait or the body of the dead natural fish bait.

[0018] The electromagnetic fish bait drive, when used for an artificial fish bait, can also be implemented by integrating the components of the electromagnetic fish bait drive in a watertight manner into the body shell of the artificial fish bait. In this case, the fish bait body comprises the body shell of the artificial fish bait.

[0019] The electromagnetic wobble drive comprises a power supply, an electromagnet comprising an excitation coil, an electronic control unit and a wobble actuator comprising permanent magnets and a wobble lever on which the permanent magnets are mounted, the wobble radius of the wobble bearing around which is Rp and generates a wobbling movement of the tail and / or the body of a dead natural bait or artificial bait with a defined deflection sm transverse to the longitudinal axis Y of the bait body. Preferably, a plurality of permanent magnets can be arranged in a manner stacked on each other attracted to each other in order to adapt the geometric dimensions of the permanent magnets and / or to change the magnetic force of the permanent magnets. It is particularly advantageous to use one or more stacked permanent magnets of cubic shape, each with an edge length of about 5 mm, a residual magnetization of 1.3 T to 1.4 T, a coercive force of 860 kA / m to 955 kA / m and >= 955 kA / m. The term permanent magnet is then also used for stacked permanent magnets. However, individual or multiple permanent magnets with a body shape, dimensions and magnetic data that differ greatly can also be used. Thus, depending on the size of the bait to be moved, an edge length or a cylinder length of 1 mm to 50 mm or a diameter of 1 mm to 50 mm of each permanent magnet can be considered. The permanent magnets are preferably of cubic shape, cuboid, disc shape, cylindrical shape, bar shape, concave or convex barrel shape or prismatic shape.

[0020] In the main alternative arrangement according to the invention of the cubic, cuboid or cylindrical permanent magnets, the effective magnetic force component of the permanent magnets emanates from the edge of the permanent magnet closest to the electromagnet as a function of the deflection sm.

[0021] For the purposes of the invention, the first pole axis P1 is the axis through the excitation coil that connects the two opposite magnetic poles of the excitation coil when an excitation current flows through it. The first pole axis P1 extends in the excitation coil along the straight line connecting its magnetic poles.

[0022] In a first alternative embodiment, the first pole axis P1 has an angle in the range of 0° + / - 30°, preferably in the range of 0° + / - 10°, in particular in the range of 0° + / - 5°, with respect to the longitudinal axis Y of the bait body and thus extends essentially parallel to the longitudinal axis Y of the bait body. The excitation coil with the first pole axis P1 is arranged at an angle in the range of 0° + / - 30° with respect to the longitudinal axis Y of the bait body.

[0023] The coil length LC in the sense of the invention is the length of the coil winding of the excitation coil in the axial direction along the first pole axis P1.

[0024] The coil height HC in the sense of the invention is the height of the coil winding of the excitation coil in the radial direction along the first pole axis P1.

[0025] Preferably, in the first alternative embodiment, the coil length or winding length LC of the field coil is 1 mm to 50 mm, preferably 3 mm to 30 mm, particularly preferably 5 mm to 20 mm, and the coil height HC is 0.5 mm to 20 mm, preferably 1 mm to 10 mm, in particular 2 mm to 4 mm.

[0026] The wire thickness DW of the winding wire used to implement the field coil has a diameter in the range of DW = 0.01 mm to 0.5 mm, preferably DW = 0.03 mm to DW = 0.15 mm, in particular 0.05 mm to 0.1 mm, using thin wire or ultra-thin wire.

[0027] In order to achieve a high magnetic induction with a low mass of the field coil and a low field current ie, in the second alternative embodiment, a flat wide coil with a low coil length LC and a relatively high winding height HC can be implemented. In this case, the coil length LC has a defined ratio to the coil height HC.

[0028] The wire thickness DW of the winding wire used to implement the field coil has a diameter in the range of DW = 0.01 mm to 0.5 mm, preferably DW = 0.03 mm to DW = 0.15 mm, in particular 0.05 mm to 0.1 mm, using thin wire or ultra-thin wire.

[0029] Preferably, in the second alternative embodiment, the coil length or winding length LC of the field coil is 0.1 mm to 15 mm, preferably 0.3 mm to 10 mm, in particular 1 mm to 4 mm. Furthermore, the coil height or winding height HC of the field coil is 0.5 mm to 60 mm, preferably 1 mm to 10 mm, in particular 2 mm to 5 mm. Furthermore, the ratio of the coil height to the coil length HC / LC of the field coil is 1 to 60, preferably 1.5 to 20, in particular 2 to 10.

[0030] Even with the use of a flat coil with a small winding length LC and a relatively large winding height HC, a high magnetic induction and thus a high magnetic force effect can be produced with a low total mass of the field coil. Since the acceleration of the lure that can be achieved by the lure driver with a = F / m is inversely proportional to the mass of the lure, and the mass of the field coil accounts for a high proportion of the total mass of the lure driver, a synergistic selection of the wire diameter DW, the coil length LC and the coil height HC parameters is very important for the movement effect that can be achieved by the lure driver.

[0031] According to the chosen size ratio of the excitation coil in the embodiments according to the second alternative embodiment, the first pole axis P1 is preferably arranged transversely to the lure body longitudinal axis Y in order to optimally utilize the volume of the lure having a height cross section which is elliptical. The coil body can be circular, elliptical, rectangular or other shape along the turns of the coil in order to optimally fit the coil body in the lure body while utilizing the available volume.

[0032] Preferably, several such coils can be wound on a common core and the windings can be cascaded, thus the motion effect which can be achieved by the lure can be enhanced while advantageously utilizing the available volume of the lure.

[0033] Advantageously, in the case of cascaded coils, a magnetic tap can be provided between the coils in order to form an E-shaped pole shoe or yoke.

[0034] In the second alternative embodiment, the first pole axis P1 is guided to the rear by at least one ferromagnetic material pole shoe or yoke on the tail side and another first pole axis P1'forming a ferromagnetic material pole shoe or yoke is preferably arranged at an angle in the range of 0° + / - 30°, preferably 0° + / - 10°, in particular 0° + / - 5° to the lure body longitudinal axis Y and thus substantially parallel to the lure body longitudinal axis Y.

[0035] In the second embodiment, said another first pole axis P1'is arranged at an angle in the range of 0° + / - 30° to the lure body longitudinal axis Y, similar to the first pole axis P1 in the first embodiment.

[0036] Further optionally in this alternative embodiment of the second embodiment, preferably the opposite magnetic poles of the electromagnet can be guided by a ferromagnetic material pole shoe or yoke to the rear of the permanent magnet from the opposite magnetic poles of the ferromagnetic material core as pole shoe or yoke, wherein both ends of the pole shoe or yoke form an air gap with the permanent magnet.

[0037] In the sense of the present invention, the second pole axis P2 is an axis through the permanent magnet which connects the two opposite magnetic poles of the permanent magnet. The second pole axis P2 extends in the permanent magnet along the direct connection line of its magnetic poles.

[0038] In the embodiments of each of the first or second embodiments, the wobble actuator is arranged relative to the longitudinal axis of the lure body such that the second pole axis P2 forms a defined angle, preferably an angle of 90° or an angle in the range of 90° + / - 40°, in particular 90° + / - 25°, to the lure body longitudinal axis Y.

[0039] The angular range of 90° + / - 40° supports the tail fin deflection required for fast fin propulsion in particular, while the angular range of 90° + / - 25° represents the fin movement range typically effective during forward movement. In addition to the fin movement range typically effective during forward movement, the advantageous range of 90° + / - 15° also includes the typical movement range of a sick or distressed natural prey.

[0040] In these embodiments, the permanent magnet is arranged with the second pole axis P2 in an angular range of 90° + / - 40° with respect to the lure body longitudinal axis Y.

[0041] In another embodiment of the first alternative embodiment, the second pole axis P2 extends in an angular range of 0° + / - 40° with respect to the lure body longitudinal axis Y, preferably 0° + / - 25° with respect to the lure body longitudinal axis Y. The angular range of 0° + / - 40° with respect to the lure body longitudinal axis Y supports the tail fin deflection required for fast fin propulsion in particular, while the angular range of 0° + / - 25° with respect to the lure body longitudinal axis Y represents the fin movement range typically effective during forward movement. In addition to the fin movement range typically effective during forward movement, the advantageous range of 0° + / - 15° with respect to the lure body longitudinal axis Y also includes the typical movement range of a sick or distressed natural prey. In this embodiment, the permanent magnet is arranged with the second pole axis P2 in an angular range of 0° + / - 40° with respect to the lure body longitudinal axis Y.

[0042] The initial position of the swing lever with respect to the lure body longitudinal axis Y is hereinafter referred to as the zero position, in which position no excitation of the electromagnet takes place.

[0043] In an embodiment of the first alternative embodiment, the permanent magnet is arranged with the second pole axis P2 in an angular range of 0° + / - 40° with respect to the lure body longitudinal axis Y, and the projection of the first pole axis intersects the zero position of the swing lever, or the other pole axis has a distance of maximum 5 mm from the second pole axis at the intersection of the pole axes (P1, P2) with each other.

[0044] In the first embodiment and the second alternative embodiment, the first pole axis P1 or the other first pole axis P1'preferably intersects the second pole axis P2 to exert a force effect. Alternatively, the first pole axis P1 or the other first pole axis P1'has a distance of maximum 5 mm, preferably maximum 2 mm, from the second pole axis P2 at the intersection of the pole axes with each other. The first pole axis P1 or the other first pole axis P1'intersects the second pole axis P2 at the zero position of the swing lever, or the first pole axis P1 or the other first pole axis P1'has a distance of maximum 5 mm from the second pole axis P2 at the intersection of the pole axes P1, P2 with each other.

[0045] In a first alternative embodiment, the field coil of the electromagnet is arranged in the bait body in such a way that the first pole axis P1 is essentially parallel to the longitudinal axis of the bait body or at an angle in the range of 0° + / - 30°, preferably 0° + / - 10°, in particular 0° + / - 5° thereto. Thus, preferably, the field coil winding of the electromagnet can be implemented along and around the longitudinal axis of the bait body, allowing to optimize the utilization of the available volume within the bait body, even in the case of a relatively narrow bait body. Thus, even a small artificial bait or a dead natural bait can accommodate as many turns of the field coil as possible in a very small spatial content. The force effect that the electromagnet is able to generate is proportional to the product of the field current ieand the number of turns N of the field coil. Thus, by increasing the number of turns of the field coil that the bait body is able to accommodate per unit volume, it is possible to reduce the field current ie, while keeping the force effect constant, thereby reducing the amount of electricity drawn from the power source. As a result, the electromagnetic bait drive advantageously enables a longer operating time of the electromagnetic bait drive with a smaller power source size.

[0046] The control of the electromagnet is particularly advantageous for an alternating polarity, including an electric double-pole alternating voltage as control voltage ueof the field coil and a double-pole alternating current as field current ie, which flows through the field coil of the electromagnet. The alternating voltage and the alternating current can have a symmetrical signal sequence in the positive and negative directions, i.e. the time integral in the positive direction is equal to the time integral in the negative direction.

[0047] Alternatively, the alternating voltage and the alternating current can have an asymmetrical signal sequence in the positive and negative directions, i.e. for example, the time integral in the positive direction is not equal to the time integral in the negative direction. For example, in the case of a bait body movement with a propeller for directional control or also for simulating a movement sequence of a sick prey, an asymmetrical control can be advantageously used.

[0048] Optionally and particularly advantageously, the field coil of the electromagnet additionally comprises a core of ferromagnetic material for amplifying the magnetic effect of the electromagnet. Due to its high magnetic permeability, the core of ferromagnetic material concentrates the magnetic field lines of the field coil, thereby amplifying the magnetic force in the air gap of the electromagnet.

[0049] In a preferred embodiment of the first alternative embodiment, the core of ferromagnetic material is arranged within the field coil, and the core of ferromagnetic material guides via a ferromagnetic material outside the field coil from a first pole end of the core of ferromagnetic material to a second pole end of the core of ferromagnetic material, forming a ferromagnetic material pole shoe or yoke, which has an air gap with the core of ferromagnetic material at the second pole end of the core of ferromagnetic material, in which air gap a permanent magnet is movably arranged, so that the projection of the first pole axis P1 through the field coil and the projection of the second pole axis P2 through the permanent magnet intersect at a defined angle in at least one position.

[0050] The pole shoes or yokes of ferromagnetic material formed by the ferromagnetic material passing outside the field coil guide the magnetic opposite poles of the central core to the permanent magnet, moving in the air gap of the permanent magnet, thus generating a drive torque for the tail fin by the swing lever and the swing bearing.

[0051] The pole shoes or yokes of ferromagnetic material made of ferromagnetic material are preferably U-shaped or E-shaped and / or at least partially pot-shaped. The pole shoes or yokes of ferromagnetic material can alternatively be formed completely pot-shaped. In the case of pole shoes or yokes of ferromagnetic material that are partially or completely pot-shaped, the pole shoes or yokes of ferromagnetic material have a bottom of ferromagnetic material at the first magnetic pole end of the ferromagnetic core and are tubular as a cylinder leading through the outside of the field coil to the second magnetic pole end of the ferromagnetic core, where an air gap is formed with the ferromagnetic core, in which the permanent magnet is arranged movably, in such a way that the projection of the first pole axis P1 through the field coil and the projection of the second pole axis P2 through the permanent magnet intersect at a defined angle in at least one position.

[0052] It is particularly advantageous if the pot-shaped pole shoes or yokes of ferromagnetic material are cut at the second magnetic pole end of the central core to match the shape of the permanent magnet and form an air gap with the edge of the permanent magnet that is as uniform as possible.

[0053] This advantageously enhances the attractive force generated by the permanent magnet, as its force acts on the central core and the pole shoes or yokes of ferromagnetic material, while the magnetic field or magnetic flux density for commutation is enhanced by the pole shoes or yokes of ferromagnetic material.

[0054] In a particularly preferred embodiment, the pole shoes or yokes of ferromagnetic material are formed U-shaped or E-shaped and / or at least partially pot-shaped.

[0055] In two alternative embodiments, the swing radius Rp is preferably chosen in such a way that, when using a ferromagnetic core, the additional magnetic force component of the permanent magnet acting on the ferromagnetic core results from the smallest critical air gap hE of the ferromagnetic core when the swing lever is in the nominal end position smE. This results in a maximum force effect Fm at the end position and, since the attractive force between the permanent magnet and the ferromagnetic core reaches a critical maximum at the end position, a limit of the deflection sm without a stop and thus without noise is produced at the end position.

[0056] An elastic stop can optionally be provided to limit the swing. The maximum is critical because at this value, due to the excitation of the electromagnet, a magnetic field compensation and thus a reversal of the movement polarity can still occur. If the radius Rp or the air gap h is too small, there is a risk that the permanent magnet will no longer be able to move away from the ferromagnetic core of the electromagnet. In this case, the distance of the swing bearing from the electromagnet L must therefore be increased, with the loss of magnetic force and thus of movement torque.

[0057] Thanks to the advantageous arrangement with a core of ferromagnetic material and ferromagnetic material pole shoes or yokes, on the one hand the high magnetic retention force of the permanent magnet is used to cooperate with the compensating action of the electromagnetic force field of the electromagnet to generate a high movement torque, in order to achieve an energy-saving compensation of the magnetic field with as low an excitation current as possible, thus enabling an energy-saving repositioning of the carried power supply and the start of the swing actuator from one end position to the other.

[0058] The power supply, the excitation coil of the electromagnet and the electronic control unit are integrated in the waterproof bait body. The permanent magnet can be located inside or outside the bait body. In both cases, preferably, no mechanical joint is provided between the electromagnet and the permanent magnet to transmit the force. The power transmission and the generation of the swinging movement are influenced by the magnetic force field.

[0059] The electromagnetic swing drive operates in a contactless manner, the drive element has no significant mechanical friction and can be operated without a stopper or preferably without a stopper, so it is virtually noiseless, which is a basic feature for successful use in fishing.

[0060] The excitation coil comprises a coil with N windings, through which an alternating excitation current ie flows after the application of a bipolar voltage ue, resulting in a magnetic field with alternating polarity.

[0061] The magnetic force in the air gap h of the magnetic field magnetic circuit is considered to be proportional according to the following formula

[0062] Fm ~ K * (ie * N / h) 2 ,

[0063] where K is a constant, including the magnetic properties of the materials used and the geometry of the magnetic circuit, ie is the excitation current flowing through the excitation coil, and N is the number of windings of the excitation coil.

[0064] Optionally, a resilient return element is provided on the swing lever, which exerts a restoring force Fr of the swing lever in the zero position direction.

[0065] Preferably, the pendulum bearing of the pendulum lever comprises an optional elastic return element, which exerts a restoring force Fr of the pendulum lever in the direction of the zero position without an excitation current ie or with a lower excitation current ie in the excitation coil, thus supporting or damping the movement of the pendulum lever. The damping restoring force absorbs kinetic energy from the electromagnetic lure driver and reduces the movement torque available for moving the lure. The restoring force of the return element is thus reduced as far as possible to produce a damping effect. Since a damping and restoring force proportional to the speed of the relative fin movement is generated during the movement in the water, the return element and the damping can optionally be omitted. When the lure is deployed in the surrounding water, the electromagnet partially transfers the electromagnetic kinetic energy from the moving tail fin, which is damped by the surrounding water, to the body housing of the lure or directly to the body housing of the lure via the lure body. Preferably, the body housing comprises fins at the top and bottom of the body housing to stabilize the lateral movement of the body housing to a defined extent, which together with the forward fin propulsion of the tail fin, really converts the movement torque of the electromagnetic lure driver into a series of movements of the forward streamlined part of the body housing to the tail fin transition zone relative to the transition zone to the tail fin and the movement of the tail fin. This results in a natural movement sequence in which the forward streamlined part of the body housing to the tail fin transition zone moves slightly and in the opposite direction to the tail fin. This movement pattern simulates the natural pattern of the typical sinuous movement of fish. The elastic return element comprises, for example, an elastomer, rubber or silicone and / or one or more permanently elastic springs made of metal or plastic. For example, the return element can be arranged in the passage of the pendulum lever through the lure body housing. Furthermore, the force of the flowing water acting on the tail fin can generate a dynamic restoring force Fr relative to the body housing of the artificial lure or relative to the body of a dead natural lure, in addition to restoring the pendulum lever, which is preferably used with the lure body.

[0066] Preferably, the material of the elastic body housing and the tail fin transition zone comprises the pendulum lever itself, so that a separate pendulum lever is no longer required. Further preferably, a permanent magnet can be located in the body housing, the tail fin transition zone or the tail fin.

[0067] In the case of arranging a separate swing lever, this preferably comprises a resilient or elastic material having a higher modulus of elasticity or a stiffer spring constant than the material of the selected tail fin and / or the surrounding housing material of the artificial fish bait or the body of the dead natural fish bait, so that the tail fin performs a trailing elastic power transmission by the biomimetic effect of the momentum transfer backwards, the so-called fin propulsion, and thus by the so-called jet from the propeller to the surrounding water. In order to be able to produce this effect, the movement torque generated by the dynamic air gap of the device according to the invention requires a synergy between the tail fin according to the invention and the powerful propeller. The increase in the movement torque associated with an increase in the swing lever deflection sm effectively supports the fin propulsion, since the movement torque increases exponentially until the end of the swing and stops at the instant of the end of the swing until the swing in the opposite direction. This advantageously produces a counter-rotating water vortex, the so-called discontinuous jet, which is repelled by the tail fin during the movement in the opposite direction, thereby producing a natural forward movement of the fish bait.

[0068] This results in an artificial fish bait or a dead natural fish bait that achieves a direct natural movement without producing unnatural mechanical vibrations from the rotating movement, the commutation, the bearings of the drive motor or from the gear box, or from the eccentric mechanism, etc. The propeller is largely noiseless, and when the tail fin moves in the water, it emits the same vibrations as a live fish in the case of a natural movement (from standing in the water to fleeing or moving in a wounded or sick state).

[0069] In the sense of the invention, in both alternative embodiments of the invention, the air gap h is the shortest distance between the nearest magnetic poles of the permanent magnet of the permanent-magnetic swing actuator and the electromagnet of the electromagnetic swing drive. The dynamic air gap is a function of the air gap during the movement of the permanent-magnetic swing actuator in relation to the deflection sm of the swing lever from its rest position.

[0070] The air gap h is arranged between the electromagnet and the permanent magnet and decreases with the deflection of the swing lever from its zero position when the swing lever is deflected, reaches a minimum value at the end position and increases beyond the end position.

[0071] The air gap h preferably varies between 20 mm and 0.01 mm, in particular between 5 mm and 0.05 mm, and preferably between 2 mm and 0.5 mm.

[0072] In synergy with the swing radius, the elastic and dynamic restoring torque, the number of windings N and the size of the excitation current ie, the smaller the air gap h, the greater the movement torque of the permanent-magnetic swing actuator that can be achieved in this case, and thus the greater the movement torque of the electromagnetic fish bait drive.

[0073] An artificial fish bait is a replica as close as possible to a natural prey, in particular a fish. It comprises a body shell covering a body of the fish bait. The body shell of the artificial fish bait preferably comprises an elastic material, such as a plastic, in particular an elastomer, rubber or silicone, which specifies an elastic modulus in the range of 0.5 MPa to 100 MPa, or a Shore A hardness in the range of 50 to 95 Shore 00 or 10 Shore A to 90 Shore A, preferably in the range of 10 Shore A to 60 Shore A, as determined according to DIN ISO 7619-1.

[0074] In a dead natural fish bait, the dead animal prey or the dead fish prey forms the body shell.

[0075] The permanent magnet can be located inside the fish bait body. In this case, the swing lever is movably mounted inside the fish bait body or on a rear outer wall thereof and is moved back and forth non-contactingly by a varying magnetic field of the field coil. In this case, the permanent-magnetic swing actuator comes out of the rear end of the fish bait body in a movable manner and is sealed against water ingress and into the tail fin, which can be provided as a mechanical swing movement. Preferably, the passage of the swing lever through the rear wall of the fish bait body comprises a permanently elastic sealing device, for example made of rubber or silicone or another elastomer, and preferably forms a swing bearing about which the swing lever of the permanent-magnetic swing actuator can be moved in a rotatably mounted manner. The swing bearing and the sealing preferably comprise an elastic material, such as a plastic, in particular an elastomer, rubber or silicone, which specifies an elastic modulus in the range of 0.5 MPa to 100 MPa, or a Shore A hardness in the range of 50 to 95 Shore 00 or 10 Shore A to 90 Shore A, preferably in the range of 10 Shore A to 60 Shore A, as determined according to DIN ISO 7619-1.

[0076] Alternatively, preferably, the permanent magnet can be located outside the fish bait body. In this case, the swing lever is movably mounted outside the fish bait body and is moved back and forth non-contactingly by a varying magnetic field of the field coil. The swing lever enters the tail fin, which is provided as a mechanical swing movement. The permanent magnet can be connected with the swing lever of the permanent-magnetic swing actuator located outside the fish bait body, or the permanent magnet can be integrated into an elastic body of the artificial fish bait tail fin region or the dead fish bait tail fin region. In these embodiments, the swing bearing is located outside the fish bait body in the body shell of the artificial fish bait or the natural dead fish bait. The swing bearing preferably comprises an elastic material, such as a plastic, in particular an elastomer, rubber or silicone, which specifies an elastic modulus in the range of 0.5 MPa to 100 MPa, or a Shore A hardness in the range of 50 to 95 Shore 00 or 10 Shore A to 90 Shore A, preferably in the range of 10 Shore A to 60 Shore A, as determined according to DIN ISO 7619-1.

[0077] In a test series of two alternative embodiments, we found that the reverse alignment, i.e. the first pole axis P1 or the other first pole axis P1'aligned parallel to the longitudinal axis Y of the fish bait body and the pole axis P2 aligned transversely to the longitudinal axis Y, compared to the alignment parallel to the pole axis P2 of the longitudinal axis Y of the fish bait body and the first pole axis P1 or the other first pole axis P1'aligned transversely to the longitudinal axis Y or the other first pole axis P1'aligned transversely to the longitudinal axis Y and the pole axis P2 aligned at a defined angle to the longitudinal axis L, preferably at a right angle to each other, leads to a surprisingly increased propulsion efficiency, whereby the parameters excitation current ie, the number of windings N and the preferably dynamic effective air gap h, which decreases with increasing deflection sm of the swing lever, which is relatively minimal at the end position and increases with further deflection sm, and optionally the elasticity and / or the elastic mounting of the permanent-magnetic swing actuator, which cooperates with the magnetic field of the permanent magnet transversely to the magnetic field of the electromagnet excitation coil, enable an increased movement torque while reducing the required excitation current ie. Optionally, the elastic mounting comprises for example an elastomer, rubber or silicone or one or more permanently elastic springs made of metal or plastic.

[0078] The value of the dynamic effective air gap h between the electromagnet and the permanent magnet decreases with increasing deflection sm of the swing lever as the swing driver moves towards its respective end position smE and is relatively minimal at the end position smE and the magnetic force effect Fm reaches a relative maximum. When passing through the respective end position, the effective air gap h increases again, the magnetic force effect Fm on the permanent-magnetic swing actuator decreases, the direction of the force vector Fmd is reversed, resulting in the swing being guided back to the end position smE, where the magnetic force effect Fm has a relative maximum. The distance h and the magnetic force effect Fm are relative, because in different embodiments the swing radius and the swing pivot distance from the electromagnet, respectively the distance L from the electromagnet core, can be chosen differently.

[0079] When the electromagnet is not excited, i.e. no excitation current ie flows through the excitation coil of the electromagnet, the swing lever of the swing actuator is optionally turned from a possible previous deflection into its zero position by elastic bearings and / or springs. The elastic bearings comprise for example an elastomer, rubber or silicone or one or more permanently elastic springs made of metal or plastic.

[0080] In the neutral position, in particular in the zero position of the deflection of the swing lever, the magnetic core of the permanent magnet is initially at a distance h0 from the electromagnetic drive coil and is aligned with the pole axis of the electromagnet or preferably with the central axis of the ferromagnetic core of the electromagnetic excitation coil. In this position, the permanent magnet exerts no force on the non-current-carrying air coil of the electromagnet or exerts a minimum force on the ferromagnetic core of the electromagnetic excitation coil at a distance h0 from the magnetic core of the permanent magnet. The swing drive is in an unstable to slightly stable equilibrium position and can already be deflected in the positive direction sm+ or in the negative direction sm- with a weak electromagnetic pulse. Once deflected, the magnetic field of the permanent magnet begins to exert its force effect Fm on the magnetic field of the air coil and / or on the magnetic field of the ferromagnetic core of the electromagnetic excitation coil and causes an increase in the deflection of the swing drive until the latter reaches the first positive end position smE+ or the second negative end position smE-, at which the air gap hE reaches a minimum and thus the force effect Fm of the magnetic field of the permanent magnet on the magnetic field of the air coil and / or on the magnetic field of the ferromagnetic core of the electromagnetic excitation coil reaches a maximum. Depending on the damping effect of the resilient swing bearing and / or the water flow forces acting on the tail fin when used in water, the end position of the swing, for example the first positive end position smE+, is reached with an undefined period transient or after a damping transient in a damping manner conforming to the e function.

[0081] The first end position is reached without obstruction and without any mechanical noise that would scare off possible prey fish. The swing drive described in the present invention operates very quietly. Resilient stops can optionally be provided to limit the swing amplitude.

[0082] In this case, advantageously, in addition to the restoring force of the tail fin moving in the water relative to the main body housing, a speed-dependent damping is preferably generated by the relative movement of the tail fin with respect to the surrounding water and / or by the optional resilient bearing, so that a restoring force Fr is generated, which suppresses the swing amplitude and / or returns the swing to the neutral or zero position when the excitation effect is significant, thus supporting the magnetic pole reversal process.

[0083] From this first end position, the oscillation drive is reversed by reversing the polarity of the voltage applied to the electromagnet field coil by flowing a counter current through the electromagnet field coil. The oppositely polarized magnetic field thus generated cancels the magnetic field of the permanent magnet and the restoring force caused by the elastic and / or spring-loaded bearing of the oscillation drive supports the acceleration of the oscillation in the direction of the second, opposite end position. In the process, the oscillation is deflected beyond the zero position under the influence of the force fields of the electromagnet and the permanent magnet. In the process, the magnetic field of the permanent magnet again begins to exert its force effect on the magnetic field of the air coil and / or the magnetic field of the ferromagnetic material core and causes an increase in the deflection of the oscillation drive until it reaches the negative end position smE-, at which position the air gap hE reaches a minimum and thus the force effect Fm of the magnetic field of the permanent magnet on the magnetic field of the air coil and / or on the magnetic field of the ferromagnetic material core reaches a maximum. Depending on the damping effect of the elastic oscillation bearing and / or the flow forces acting on the tail fin when used in water, the second end position of the oscillation is reached with a damped, e-function-like, aperiodic transient or after a damped transient.

[0084] The second end position is reached without a stop and without any mechanical noise that could scare off possible prey fish. The oscillation drive described in the present invention operates very quietly. An elastic stop can optionally be provided to limit the oscillation amplitude.

[0085] The reversing process is preferably supported by the intersecting pole axes of the electromagnet and the permanent magnet. Less reverse energy is required compared to a parallel arrangement of the pole axes. The electromagnet fishing lure is thus driven by a lower field current from the electromagnet, which means that the power requirement of the power supply is lower. As a result, the electromagnet fishing lure drive achieves a longer operating time of the electromagnet fishing lure drive with a smaller power supply size.

[0086] The mass of the oscillation actuator together with the elastic oscillation bearing forms a mechanical oscillating spring / mass system, the mechanical resonance frequency of which depends on its spring constant and mass. The electrical activation of the field coil preferably has a periodic field voltage ue and a periodic field current ie, the frequency of which is approximately the same as the mechanical resonance frequency of the oscillating spring / mass system. The mechanical resonance of the oscillation actuator is thus also used to generate the movement torque.

[0087] By particularly advantageous bipolar control, an attraction of the permanent magnet to the pole of the electromagnet occurs by opposite pole excitation of the field current ie in the electromagnet relative to the polarity of the permanent magnet, whereby the swing lever leaves its zero position. This is particularly advantageous if the field coil is arranged with a ferromagnetic material core, because the permanent magnet exerts a permanent magnetic attraction on the ferromagnetic material core in the air gap, thereby generating an additional magnetic force. Conversely, when the field current ie in the electromagnet is homopolar relative to the polarity of the permanent magnet, the permanent magnet repels the pole of the electromagnet, causing the swing lever to move towards the zero position. If the field coil is arranged with a ferromagnetic material core, the additional magnetic force exerted by the permanent magnet on the ferromagnetic material core in the air gap has to be overcome.

[0088] Preferably, the acceleration from one end position to another end position is initiated by a current pulse having a defined duty cycle compared to the driving frequency or the period of the swing driver. The input current pulse ie for the excitation of the excitation coil can optionally and preferably have a smaller time integral compared to the case of symmetrical or asymmetrical control. The integral of the current over time is the charge taken from the power supply for the activation. With the same amount of charge, a reduced pulse width can increase the current pulse ie and thus the restoring torque, which increases the propulsion moment of movement, or can reduce the amount of charge taken from the power supply while the movement moment is the same, so that the operating time of a particular power supply can be extended or a smaller power supply can be used with a comparable operating time. The current pulse of the excitation current ie required to reverse the swing lever only needs to be able to bring the swing lever to a defined position between the end positions, preferably between one of the end positions and the zero position.

[0089] The impedance of the excitation coil depends on the air gap between the ferromagnetic material core and the swing lever permanent magnet. Since the air gap changes dynamically with the position of the swing lever, the impedance of the excitation coil can advantageously be used to determine the position of the swing lever, for example by evaluating the excitation current ie progression with a current sensor, for example a current measuring resistor, and transmitting it to the electronic control unit for further processing.

[0090] Alternatively or additionally, the magnetic field strength in the air gap can be detected by a magnetic field sensor, for example a magnetic field-dependent resistor or a Hall sensor, and transmitted to the electronic control unit for further processing. The measured magnetic field strength is a measure of the air gap and thus of the position of the swing lever. Other sensors can be used to detect the position of the swing lever.

[0091] Advantageously, means are optionally arranged to detect the current position of the swing driver and to transmit an electrical position signal to the electronic control unit. The electronic control unit determines from the current position of the swing driver whether and how much excitation current ie of the electromagnet is required for the reversal, i.e. whether excitation current ie is required and in which direction, or whether excitation current ie can be reduced or switched off without hindering the reversal process.

[0092] The reversal process of the swing lever from the end positions smE+, smE- is carried out by the excitation current ie through the electromagnet excitation coil, whereby the excitation current ie is switched off or reduced when the swing lever reaches a defined position between the end positions smE+, smE-.

[0093] Preferably, the defined position is located between one of the end positions smE+, smE- and the zero position of the swing lever.

[0094] Optionally, a device for detecting the position of the swing lever is provided, which switches off or reduces the field current ie by means of the electronic control unit. The device for detecting the position of the swing lever comprises a magnetic position sensor or a capacitive position sensor or an optoelectronic position sensor or an inductive position sensor and / or a position detection by detecting and evaluating the air gap-dependent field current ie.

[0095] Alternatively or additionally, the field coil of the electromagnet can be controlled by an electrical high-pass filter, for example by a capacitor in series with the impedance of the field coil, which dynamically generates a high field current pulse in the electromagnet field coil, thereby limiting the charge taken from the power supply. During the activated reversal process, the field voltage ue applied to the field coil is doubled by the capacitor charged from the previous activated phase, initially dynamically reduced according to an e-function, and due to the amplitude of the current pulse generated in this way, the magnetic induction of the electromagnet can be increased for the reversal, the charge taken from the power supply is reduced, and as a result a smaller air gap can be selected, thereby increasing the movement torque of the swing drive.

[0096] Alternatively, the field coil can be operated in parallel or in series with a capacitor as a resonant circuit, whereby the energy consumption of the thruster is particularly low, since in resonance only the energy losses have to be made up to maintain the movement torque. The mechanical resonance frequency depends on the oscillating mass of the swing actuator and its spring constant, and is preferably approximately the same as the electrical resonance frequency of the resonant circuit. The mechanical frequency of the swing actuator and the electrical frequency of the activated resonant circuit are matched to each other in the range of 0 to 30%, preferably in the range of 0 to 10%, in particular in the range of 0 to 5%.

[0097] In this case, the field coil of the electromagnet is driven by an oscillating circuit, which is periodically activated by a field current pulse ie, limiting the charge taken from the power supply.

[0098] A DC converter is preferably arranged between the power supply and the electronic control unit and the thruster, which adapts the voltage of the power supply to a higher voltage for the power supply of the electronic control unit and the thruster.

[0099] Alternatively, the electromagnet can also be controlled by monopolar control instead of bipolar control, preferably including periodic electric monopolar control, but is not preferred since monopolar control has lower electromagnetic and mechanical reversal energy compared to bipolar control. In monopolar drive, the magnetic core must be demagnetized at the time of cut-off and before the next periodic magnetization, and appropriate means must be provided. These means consume magnetic energy and reduce propulsion efficiency. On the other hand, bipolar control of the electromagnet is preferably achieved by bipolar power supply, or in the case of monopolar power supply, by full bridge with or without coupling capacitor in series with the field coil or by half bridge with coupling capacitor in series with the field coil. Due to the required return torque of the elastic bearing and / or spring, energy must be applied for mechanical deformation, losing drive energy. On the other hand, bipolar control advantageously controls the magnetization of the magnetic core without the disadvantages of monopolar control. Bipolar control is therefore more efficient and can convert higher drive power. In monopolar actuation, the zero position is located at one of the end positions and is moved from the possible deflection position before the electromagnet is not excited, i.e. when no current flows through the field coil of the electromagnet, to its zero position by an elastic bearing and / or spring. The elastic bearing comprises, for example, an elastomer, rubber or silicone or one or more permanent elastic springs made of metal or plastic.

[0100] In order to firmly connect the bait body to the fishing line of the angler, at least one connection means, such as an eyelet or a clip or a line swivel or a spring hook, is preferably provided on the bait body in two alternative embodiments. Alternatively, the connection means can be connected to the bait body housing independently of the bait body. Optionally, a plurality of connection means can be provided at different positions, adjusting the connection position of the fishing line depending on different control situations. Optionally, at least one connection means is adjustably and lockably arranged on the bait body. The fishing line is connected to one of the connection means using known connection techniques, such as a knot or a line clip. The fishing line can comprise a plurality of components, such as a leader, a main line and optionally a backing behind the main line. On the side of the angler, the fishing line preferably passes through the eyelet of the fishing rod from the end of the fishing rod to the line winding device operable by the angler.

[0101] At the connection means for connecting the bait body or the bait body housing to the fishing line, a component of the inertial force Fyr caused by the fishing line comes into play when the artificial bait or the dead bait is moved, for example when the artificial bait or the dead bait is reeled in and / or when the fishing rod is jerked. The angler can cast the artificial bait integrated with the bait body or the dead natural bait integrated with the bait body as usual, or he can put it into the water from the shore or from a boat and direct it to a place where it is suspected that predatory fish can be captured by the movement of the artificial bait integrated with the bait body or the dead natural bait integrated with the bait body and predatory fish can be attracted.

[0102] Optionally, a further controller device can be provided to control components arranged in the lure body.

[0103] For the controller of the lure body components, a message detection device can preferably be provided in the lure body, which converts a lure body connection point to the angler's fishing line inertial force component Fyr or a specified change in the speed v or the inertial negative acceleration of the lure body, in particular a short, sudden change or a longer, dragging change, into electrical signals, which are decoded by the electronic control unit and converted into electrical control commands for controlling the control actuator and / or the electromagnetic field coil of the oscillation drive. The message detection device can comprise, for example, an acceleration sensor, for example an integrated MEMS sensor or a wire sensor. The acceleration sensor is particularly advantageous when the connection device is not connected to the lure body, but can also be used when the connection device is connected to the lure body. The wire sensor is preferably configured when the connection device is connected to the lure body. The wire sensor comprises a switch with a force-specific defined switching point or a sensor for converting a force simulation into an electrical value, for example a piezoelectric element, a strain gauge, a photoelectric sensor, an inductive sensor or a capacitive sensor or a pressure sensor.

[0104] In this way, the angler can generate different mechanical signals or time-defined pulses using the conventional fishing assembly, for example by pulling the fishing rod tip sharply backwards or partially crashing it, which are mechanically transmitted to the lure body by the fishing line, which the message detection device receives as a signal by the time-defined and / or sudden change. In this way, the angler can advantageously emit one controller message or a plurality of coded controller messages, which control the lure body by a single signal or by a time sequence of signals. Preferably, the length of the signals can also be different, so that individual characters and / or entire words comparable to Morse code are sent to the lure body for controlling the control actuator and / or the electromagnetic oscillation drive. Preferably, at least one start symbol and / or at least one end symbol is optionally agreed, wherein a sequence of characters with or without start symbol or end symbol is interpreted as a message. Additionally or alternatively, a time window from the first character can be agreed, within which a sequence of characters is interpreted as a message.

[0105] The electronic control unit comprises an electronic circuit, preferably a programmable microcontroller with program memory, data memory and corresponding drivers, for controlling the control actuator and / or the electromechanical oscillation drive. The electronic control unit preferably comprises a decoder for decoding the electrical signals converted by the message detection device. The semantic assignment or meaning of the message coding can preferably be fixed in the decoder or optionally programmed by the angler via an interface of the electronic control unit.

[0106] The interface can be a wired interface on the bait body with sealable contacts, for example a USB interface or an RS232 interface, or a wireless interface in the bait body, for example a Bluetooth interface or a WiFi interface. For programming the electronic control unit, on the angler side, a computer can be used, for example a stationary or portable computer, a tablet or a smartphone or other communication device. Preferably, the computer has a further interface for connecting to a remote computer or the Internet, in order to be able to download ready-made programs or updates therefrom, to program the electronic control unit of the bait body. Preferably, particularly successful movement patterns can be provided and downloaded therefrom for controlling the thrusters.

[0107] The electromagnetic bait drive can be controlled in response to a decoded message from the angler or based on a preprogrammed selection of programs when the electromagnetic bait drive is put into operation.

[0108] Preferably, means can be provided by which the electromagnetic wobble drive according to the application can be controlled with respect to frequency and / or amplitude and / or temporarily switched off or on. The frequency determines the number of deflections of the tail fin per unit of time. This makes it possible to determine the speed of the movement on the one hand and the type of movement on the other hand. In the case of a tail-side propulsion by means of a magnetic wobble of the tail fin, the amplitude of the deflection of the tail fin can be used to determine the intensity of the movement. For example, a controller can be distinguished between a normal movement and a sick movement pattern.

[0109] For example, the electromagnetic bait can be controlled such that the periodic electrical activation of the propulsion excitation takes place with an asymmetric time profile, and the tail-side propulsion of the tail fin can be set to an asymmetric oscillatory movement.

[0110] The amplitude deflection, i.e. the integral of the force generated and thus the work performed, is thus shifted in the positive and negative direction, respectively, relative to the middle center position of the tail fin, the direction time-dependent position of the tail fin, so that the direction control is achieved by the asymmetric wobble movement of the tail fin. Depending on the vertical or horizontal direction of the tail fin in the middle position, a movement controller of an artificial bait integrated in the bait body or of a dead natural bait integrated in the bait body can be realized in this way.

[0111] The power supply for the electronic control unit for controlling the actuator and for powering the thrusters can be a battery or can be a rechargeable power supply, for example an accumulator or a capacitor, for example a so-called "super capacitor". In the case of a rechargeable power supply, the charging can be done via an external power source, for example a cigarette lighter of a car battery, or an external accumulator, for example a "power pack", and via a wired interface.

[0112] Alternatively, a wireless charging process similar to an electric toothbrush can be employed, in which the electrical energy is inductively or capacitively transferred to a receiving unit in the bait body and from there to its rechargeable power supply.

[0113] To optionally provide a waterproof access for replacing the battery or an access for connecting a wired interface, preferably a screw cap or a sealing plug is provided on the bait body with a seal, which detachably and reclosably opens and recloses the waterproof access for the battery and / or the wired interface.

[0114] The control device can optionally also comprise a sealing switch device, which is operable from outside the bait body, which forms and breaks the electrical connection between the power supply and the electrical loads, such as the field coil of the electromagnetic wobble drive, the electronic control unit, the drive driver controlling the electromagnetic wobble drive field coil, and optionally sensors and control actuators in the bait body. Alternatively, the electrical connection between the power supply and the electrical loads is formed and broken by inserting or removing the power supply into or from the bait body or via corresponding connection contacts (jumper wires) on the bait body.

[0115] Optionally, further manually operable control actuators, such as switches or potentiometers or the like, can be provided for setting the frequency and / or the amplitude and / or the duty cycle, respectively, the time-symmetric or time-asymmetric curve progression of the electromagnetic wobble drive and / or the required control program version and / or for moving the center of buoyancy and / or the center of gravity and / or the flow bodies (such as one or more elevators and / or rudders). The manually operable control device is set by the angler before submerging the bait body or body housing according to the desired control options. Thus, the angler forms the electrical connection from the power supply to the electrical components of the electromagnetic wobble drive before submerging the bait body or body housing.

[0116] Optionally, at least one tracking device is provided in the bait body. Positioning devices, in particular GPS positioning devices or acoustic and / or optical positioning devices, such as ultrasonic transmitters and / or LEDs. The positioning devices are preferably used to retrieve lost bait bodies.

[0117] In a first alternative embodiment, the field coil of the electromagnet is preferably formed longitudinally and mainly rotationally symmetrically within the bait body along its longitudinal axis. The pole axis PI of the electromagnet thus extends essentially parallel to the longitudinal axis of the bait body. The field coil preferably comprises a core of ferromagnetic material, which ends at the rear outer wall within the bait body or projects to the rear of the bait body by the latter, in order to exert a back force effect from there on the permanent magnet with dynamic air gap, which then oscillates back and forth laterally. This means that a narrow and long bait body with a high movement torque can also be realized.

[0118] In a second alternative embodiment, at least one field coil ferromagnetic material pole shoe or yoke transverse to the longitudinal axis Y of the bait body is arranged, which, in synergy with the requirement to achieve a high movement torque with as low an electrical energy consumption as possible, supports the streamlined design of the bait body housing.

[0119] In both alternative embodiments, at least one ferromagnetic pole shoe or yoke of the ferromagnetic material core advantageously amplifies the concentration of the polarity-alternating magnetic field lines. The ferromagnetic pole shoe or yoke of the ferromagnetic material core further supports the non-contact end position of the wobble actuator, as a balance of repulsive and ferromagnetic attractive forces is established, which limits the angular deflection even without a stop, thus without noise, which cooperates with the fin deflection damped by the water, resulting in a propulsion-like acceleration of the fin. A resilient stop can also be optionally provided to limit the swing amplitude.

[0120] The at least one longitudinal ferromagnetic pole shoe or yoke, or the longitudinally rotationally symmetrical field coil, cooperates with the requirement to achieve a high movement torque with as low an electrical energy consumption as possible, advantageously supporting the streamlined design of the lure body housing.

[0121] The electromagnetic wobble drive can be realized in a compact and cost-effective manner and can be controlled and programmed in a simple manner by changing the electrical excitation voltage, thus changing the profile shape, frequency, amplitude and duty cycle or time-symmetrical or asymmetrical profile progression of the electrical excitation current flowing through the electromagnet field coil.

[0122] The electromagnetic lure drive can thus be integrated in a space-saving manner even in small natural or artificial lures and operates efficiently by exploiting the force effect of the permanent magnet by means of a dynamic air gap, thus generating a higher movement torque in the electromagnet field coil with a low excitation current, so that the size of the power supply can be reduced, the operating time of the battery can be extended or the charge of the accumulator can be increased. At the same time, the electromagnetic lure drive hardly produces unnatural turning, beating or flipping noises. This makes the electromagnetic lure drive an efficient and economical fishing accessory for artificial lures, suitable for a wide range of fishing accessory markets and capable of moving dead natural lures in a way that is attractive to predatory fish.

[0123] In addition to the lateral wobbling movement of the lure, the propeller generates a total force component Fyv at the drive point, the direction of which is forward in the y direction at the drive point. The position of the drive point depends on the shape, area and material of the tail fin and the fluid design of the lure body. The drive point is preferably located in the rear half of the lure in the transition region of the tail fin, in particular in the wobble bearing pivot region.

[0124] Optionally, a float can be connected to the bait body so that in addition to the buoyancy of the bait body, an upward buoyancy component Fa is generated. The float can be connected to the bait body in a defined manner at one or more front first connection devices. Alternatively, the position of the front first connection devices for connecting the float can be adjusted and arranged to be permanently held in one position or fixed. Alternatively, the front first connection devices for connecting the float are connected to the bait body via a front first extension element. Preferably, the front first extension element comprises an elastically deformable material, for example metal or plastic, and remains in a set shape before the next deformation. By these measures, the inclination of the bait body with respect to the vertical axis can be statically adjusted in coordination with the weight of the propeller and the bait components, for example the power supply, the control electronics, the connection devices, the inclination of the bait body with respect to the vertical axis can be dynamically adjusted in coordination with the positive sum of the force components Fyv generated by the propeller in the y direction, and the depth position of the bait body with respect to the surrounding water surface can be explicitly adjusted by the angler.

[0125] The natural lateral and / or forward movement course generated by the sum of the force components Fyv generated by the forward propulsion in the y direction depends on the mass of the bait propeller relative to the mass of the remaining components of the bait and thus the downward gravity, the upward buoyancy in the surrounding water, the fluid design of the bait body and the tail fin, as well as the connection of the fishing line and the optional connection of an additional upward buoyancy component of the float.

[0126] The most natural lateral and / or forward movement of the bait generated by the propeller and optionally its controllability with respect to the movement direction v and the depth of the bait in the surrounding water body determined by the angler are determined by the position of the front first connection devices and the rear second connection devices and the front first offset point and the rear second offset point of the fishing line. The position of the connection devices and their offset points, as well as the propeller, form a synergetic effect that supports the task of establishing the natural movement course of the bait.

[0127] The fishing line can be connected at any position on the bait body, depending on the required lateral and / or forward movement v in the surrounding water body. If a defined controllable forward movement v is to be achieved, the fishing line should be fixed behind the drive point, preferably behind the swivel bearing or the rotational axis of the auxiliary straight-swivel bearing, which extends axially inside the swivel bearing, as the natural movement course of the bait body moves away from the angler.

[0128] Thus, in a preferred embodiment, the fishing line is connected behind the swivel bearing pivot of the propeller, seen from the head end of the bait body.

[0129] When using a float, the position of the first connection means connecting the float to the front of the bait body is preferably chosen such that the longitudinal axis Y of the bait body is substantially horizontal or at a desired angle of inclination in the surrounding water. The distance between the first connection means connecting the float to the front of the bait body and the float floating on the surface of the surrounding water determines the depth at which the bait moves due to the propulsion of the propulsion means.

[0130] The float is either connected to the bait body independently of the fishing line or the fishing line is preferably moveably guided through a second rear connection means forming a second rear deviation point on the bait body to a first front connection means forming a first front deviation point on the bait body, through which first front connection means the fishing line is also moveably guided and led to a float body to which the fishing line can be connected.

[0131] Preferably in one embodiment a connection tube is provided in the bait body through which the fishing line is guided, the second rear opening of which forms the second rear deviation point and the first front opening of which forms the first front deviation point.

[0132] In order to limit the relative movement of the fishing line and the fastening means at the deviation points, a fishing line stop is adjustably fixed at the fishing line between the angler and the bait and is adhesively fixed at the fishing line until the next adjustment.

[0133] The force component Fyv generated by the propulsion means in the y direction initially results in the bait leaving this position again until the movement generated by the propulsion means moves the float along a section of the fishing line between the bait and the float, so that the float is subjected to an upward force component balancing the downward force of gravity, pulls the fishing line stop back to the second rear deviation point of the second rear connection means on the bait body and stabilizes the position of the bait on the fishing line and thus the depth of the movement of the bait.

[0134] By this installation, depending on the task, a defined natural forward movement with a speed v in the direction of movement y is achieved in cooperation with the propulsion means.

[0135] By optionally classically mounting the float on the bait body, depending on the task, a defined natural movement is advantageously achieved in cooperation with the propulsion means, mainly by the lateral movement of the bait in the surrounding water in the area of the bait.

[0136] The thruster is also suitable for applications of wobble drives, in which the size and capacity of the limited power supply is a limiting feature. For example, the drive can be used in toys or technical wobble applications with limited electrical drive energy, for example in propulsion applications in the aerospace industry or in solar wobble drives or pendulum motors, which can be used permanently even in low light conditions, for underwater robots, for drives or actuators that are essentially low-noise, for example in watches, or in robots as wobble actuators or wobble motors for the low-noise and efficient generation of power, for example in household appliances, such as shavers, toothbrushes, milk frothers, egg beaters, fan ventilators, massage rods, or in medical technology, for example in dental technology, for cleaning, gentle removal of dental plaque or for grinding or polishing teeth, in surgical operations for driving electric scalpels or for driving body fluid pumps or for feeding food or for permanent low-noise massage or treatment of sensitive body parts, for compensation or excitation of symmetrical or asymmetrical vibrations in mechanical or acoustic systems, etc.

[0137] In order to control the electromagnetic lure drive, the following method steps can be used, for example:

[0138] - the lure body of the electromagnetic lure drive according to the invention is arranged in a body shell of an artificial lure or in a body shell of a dead natural lure;

[0139] - the fishing line is connected to the connection means of the lure body and / or the body shell;

[0140] - an electrical connection from the electromagnetic power supply to the electrical components of the electromagnetic wobble drive is produced;

[0141] - the body shell is placed in the surrounding water.

[0142] Advantageously, the following supplementary method steps can optionally be used to control the electromagnetic lure drive:

[0143] - an electronic control unit comprising a decoder is provided in the lure body or in the body shell;

[0144] - information detection means, in particular sensors, are provided for detecting changes in the drag between the lure body or the body shell and the fishing line and / or changes in the speed of the lure body or the body shell;

[0145] - the angler encodes messages via changes in the drag on the fishing line and / or via changes in the speed of the lure body or the body shell caused by changes in the drag on the fishing line;

[0146] - the encoded messages are decoded by the decoder in the lure body or the body shell;

[0147] - in response to the decoded messages, control actions are carried out by at least one control actuator and / or the electromagnetic wobble drive.

[0148] It is not necessarily required to follow the order of the method steps as shown. Individual method steps can be brought forward or postponed without changing the validity of the presented method examples. BRIEF DESCRIPTION OF DRAWINGS

[0176] The present preferred embodiment of the application will now be described in more detail with reference to the accompanying drawings. Like parts shown in the figures have the same reference numerals.

[0177] Figure 1 A fisherman 2, a fishing assembly 10, 11, 12 placed in a body of water 3 and a bait 1 are shown. The fishing assembly comprises a reel 12, a fishing rod 11 and a fishing line 10 between the fisherman 2 and the bait 1. In the shown example, the bait 1 moves with a relative speed v in the surrounding body of water 3 in a direction y and drags the fishing line 10 behind it. Alternatively, the bait 1 can be cast to move with or without a controlled manner of the relative speed v to imitate a moving prey fish. In practice, an experienced fisherman 2 will take care to ensure that the fishing line 10 is tight enough to enable selective jerking of the fishing assembly in case a fish bites the hook, i.e. by jerking the fishing line 10 towards itself, to ensure that the hook of the bait 1 is bitten by the fish.

[0178] In Figure 2 , an embodiment of a bait 1 with a tail side propeller 330 for propulsion with an electromagnetic bait drive and a vertically oriented tail fin 103 is shown in a cross section C-D of a side view. Instead of a vertically oriented tail fin 103, a horizontally oriented tail fin 103 can be arranged for propulsion with an electromagnetic bait drive. The fishing line 10 connected to the fisherman 2 (see Figure 1 ) is connected to the connection device 130 at a connection point 230. At this point, an inertial force component Fyracts, which in case of a forward movement of the bait is caused by a backward force of the fishing line 10 connected to the fisherman 2, which is caused by a friction of the fishing line 10 connected to the fisherman 2 on the surrounding body of water 3 (see Figure 1 ) on the one hand and by a counter force of the fishing rod assembly on the other hand.

[0179] Optionally, a plurality of connection devices 130, 130' can be provided at different positions to adjust the position of the connection point 230 of the fishing line 10 connected to the fisherman 2 according to different control situations. Optionally, at least one connection device 130, 130' is adjustably and lockably arranged on the bait 1.

[0180] The bait 1 has a buoyancy center 200, wherein the bait 1 immersed in the surrounding body of water 3 is subjected to an upwardly directed water surface buoyancy force by draining water. When the shape of the bait 1 is substantially fixed, the position of the buoyancy center 200 can be changed by an artificial swim bladder 440 (compare Figure 4 ) arranged in the bait 1 by its position and / or volume.

[0181] The fishing lure 1 also has a center of gravity 210, wherein the fishing lure 1 introduced into the surrounding water body 3 is subjected to a gravitational force directed downwards to the bottom of the water body caused by the earth's gravity. The position of the center of gravity 210 can be changed by changing the position of a relatively heavy element of the fishing lure 1, such as the power source 420 (compare Figure 4 ) or an optional ballast (not shown).

[0182] The fishing lure 1 is designed for the positions of the center of buoyancy 200 and the center of gravity 210, with the center of buoyancy 200 being located above the center of gravity 210 when the fishing lure 1 is immersed in the surrounding water body 3. This ensures a stable position of the fishing lure 1. Alternatively, the floating attitude can generate or supplement the buoyancy. In addition to the generated buoyancy, it is also advantageous to indicate the position of the fishing lure 1 on the water surface. The connecting line through the center of buoyancy 200 and through the center of gravity 210 is referred to hereinafter as the vertical axis 250. For the static adjustment of the fishing lure 1, the vertical axis 250 points in the direction of the center of gravity of the earth, i.e. in the direction of the bottom of the water body in which the self-moving artificial fishing lure 1 swims.

[0183] For the dynamic control of the existing relative speed v between the fishing lure 1 and the surrounding water body 3, flow bodies such as the optionally shown elevators 122 and 121 (see Figure 3 ) and / or the optionally top-mounted rudder 120 and / or the optionally bottom-mounted rudder 120' and the like can be provided at the main body housing 100 of the fishing lure 1 as controller means. The controller means 120, 120', 121, 122, if present, are fixed or manually adjustable, for example by means of a manually operable control actuator 450 (see Figure 4 ) of the fishing lure 1 and / or by means of an electric control actuator (not shown).

[0184] In the shown embodiment, the tail fin 103 is oriented vertically. In this case, the oscillating movement transverse to the movement direction y takes place in the positive and negative direction of the horizontal x-axis (see, for example, Figure 3 or Figure 5 ).

[0185] Figure 3 A cross-section A-B of an embodiment of the fishing lure 1 with a tail side thruster 330 and a vertically oriented tail fin 103 is shown in a top view. Figure 2

[0186] Figure 4 The arrangement of the control means and the drive means in the fishing lure 1 is shown in a C-D sectional view in a side view.

[0187] In one embodiment, the permanent magnet 313 is arranged inside the fishing lure body, which is indicated by a solid line. Alternatively, in one embodiment, the permanent magnet 313 is arranged outside the fishing lure body 102, 102', which is indicated by a dashed line. ​

[0188] In addition to the fish bait body 102, 102', the electromagnetic fish bait drive comprises an electromagnetic wobble drive. The electromagnetic wobble drive comprises a power supply 420, an electromagnet 300, an electronic control unit 410 and a wobble actuator 310 comprising a permanently magnetic body 313 arranged moveable transversely to the fish bait body longitudinal axis Y and a swing lever 312 on which the permanently magnetic body 313 is mounted for a wobble movement with a wobble radius Rp around a wobble bearing 311, the wobble movement of the dead natural fish bait 1 or artificial fish bait 1 having a defined deflection sm transversely to the fish bait body longitudinal axis Y (see Figures 7a to 9b ).

[0189] The electromagnet 300 exerts an electromagnetic force on the permanently magnetic body 313, resulting in a wobble movement transversely to the fish bait body longitudinal axis Y, which is transmitted via the swing lever 312 and the tail fin transition region 101 to the tail fin 103. Preferably, a movement torque can be generated by the wobble bearing 311 and an overdrive or low speed drive can be provided.

[0190] The electromagnet 300 comprises an N-winding field coil 301 with or without a ferromagnetic material core 302 (see Figure 6a and 6a ' to 7d, and Figure 11 and 12 ). Upon excitation with an excitation voltage ue (see Figures 7a to 7d ), an electric excitation current ie flows through the windings of the field coil 301 and, depending on the direction of the current, an output magnetic field with a defined polarity N, S is generated at the ends of the field coil 301 or at the ends of the ferromagnetic material core 302.

[0191] For controlling the electromagnetic wobble drive by means of the electromagnet 300, a drive driver 400 is provided as part of the electronic control unit 410, which provides the signals required for driving the excitation 300, in which these signals have a defined curve progression of the electric excitation voltage ue or the electric excitation current ie as a function of time. Preferably, the electronic control unit 410 comprises discrete and / or partially integrated electronic components and / or programmable microcontrollers. The control signals of the electronic control unit 410 are provided to the drive driver 400 as digital signals or as analog signals. The drive driver 400 converts this signal into an electric unipolar excitation voltage ue or into a bipolar excitation voltage ue or into an electric unipolar excitation current ie or into a bipolar excitation current ie, respectively. For this purpose, the power supply 420 provides a unipolar power supply voltage or a split, i.e. bipolar, power supply voltage, which is oriented positively and negatively with respect to a potential point located between the total voltages. In the case of bipolar control, the drive driver 400 comprises means, for example a bridge circuit, for alternating the polarity of the excitation voltage ue and the excitation current ie. Preferably, the drive driver 400 comprises an electronic H-bridge for generating the bipolar excitation voltage ue and the bipolar excitation current ie, respectively.

[0192] A line sensor 430 and / or an acceleration sensor 431 can optionally be provided as a message detection device in the electronic control unit 410. The message detection device optionally detects a change in the reverse force component Fyr or a reverse time velocity change dv / dt at the connection point 230 as a negative acceleration value of the lure 1 as a signal transmission message and converts them into an electrical signal and provides it to the electronic control unit 410 for further evaluation of the time sequence of the signal and, if necessary, decoding.

[0193] The message detection device can comprise, for example, an acceleration sensor 431, for example an integrated MEMS sensor and / or a line sensor 430.

[0194] In the case of an acceleration sensor 431, the detection takes place by a spring-mass acceleration sensor in the lure 1. Such an inertial sensor evaluates the inertial forces acting on a mass and can be implemented well in a compact and cost-effective manner on a silicon base with so-called MEMS structures within an integrated electronic component. When a prescribed threshold value of the acceleration dv / dt detected in this way is exceeded, a signal is detected which is provided to a decoder for decoding.

[0195] The line sensor 430 comprises a switch with a prescribed switching point specific to the force, which changes its electrical switch contacts in a prescribed manner at a prescribed mechanical inertial force component Fyr of the connection point, so that an electrical signal is generated at a prescribed inertial force component Fyr of the connection point, or comprises a sensor for the analog conversion of the inertial force component Fyr of the connection point into an electrical value, for example a piezoelectric element, a strain gauge, a photoelectric sensor, an inductive sensor, a capacitive sensor or a pressure sensor.

[0196] Electric power is supplied to the electrical components of the electromagnetic oscillation drive by a unipolar power source 420 or by a separate bipolar power source 420. A battery or a rechargeable power source, for example a storage battery or a capacitor, for example a so-called "super capacitor", can be provided as a power source 420 to power the electronic control unit 410 controlling the actuator, the drive 400 and the electromagnet 300. In the case of a rechargeable power source 420, charging can be done via a wired interface 460 by an external power source, for example the cigarette lighter of an automobile battery, or an external rechargeable battery / "power pack".

[0197] Preferably, a DC converter 421 is arranged between the power source 420 and the electronic control unit 410 and the electromagnet 300, which adapts the voltage of the power source 420 to a higher voltage for powering the electrical components of the electromagnetic oscillation drive. Preferably, the voltage converter is implemented in the form of an inductive boost converter, for example a so-called boost converter or voltage step-up converter. In this case, a low input voltage of 0.8 V to 3.8 V is boosted to a higher output voltage of 2.0 V to 18 V.

[0198] The advantage of this arrangement is that single or multi-cell simple e.g. alkaline / manganese or e.g. lithium batteries can be used, which are available in various forms, e.g. in AAA or AA form or in various sizes of button cells, are widely available, have a high charge capacity and can be used to operate the thruster and the electronic control unit. The cell voltage of a single cell alkaline battery is 1.5 V. The actual available voltage of an alkaline / manganese or iron sulfide lithium battery is 1.2 V to 1.7 V. The actual available voltage range of other lithium batteries is 2.0 V to 3.8 V.

[0199] Furthermore, the advantage of this arrangement is that single or multi-cell simple rechargeable batteries, e.g. NiCd or NiMh or lithium ion or NiZk technology (hereinafter referred to as accumulators), which are available in different forms, e.g. in AAA or AA form or in various sizes of button cells, are inexpensive, widely available, have a high charge capacity and can be used to operate the thruster and the electronic control unit. The cell voltage of a single cell NiCd or NiMh battery is 1.2 V, the cell voltage of a NiZk battery is 1.6 V. The actual available voltage range of these batteries is 0.8 V to 1.7 V. The cell voltage of a single cell lithium ion battery is 3.7 V. The actual available voltage range of this battery is 3.0 V to 3.8 V.

[0200] Depending on the input voltage range 0.8 V to 3.8 V, the following particularly preferred input voltage ranges for the DC converter result:

[0201] - 0.8 V to 1.7 V

[0202] - 2.0 V to 2.8 V

[0203] - 3.0 V to 3.8 V

[0204] Single cells can also be connected in series. The input voltage range thus obtained is an integer multiple of the cell voltage mentioned above.

[0205] In order to have a sufficiently high voltage swing for the control of the electromagnetic thruster, even when using an H-bridge, bipolar integrated circuits with a 4.5 V lower operating voltage (selected from 3.5 V) or integrated CMOS circuits with a 2.5 V lower operating voltage (selected from 2.0 V) can be considered.

[0206] The upper supply voltage limit of these circuits is usually 18 V. This results in an output voltage range of the DC converter of 2.0 V to 18 V. Preferably, the output voltage range is 4.0 V to 6 V, particularly preferably 4.5 V to 5.5 V.

[0207] In order to move the center of gravity 210 (see Figure 2) can be changed in its position within the main body housing 100 of the self-moving fishing lure 1 by changing the mass of the power source 420 and / or the mass of the ballast (not shown) optionally by an electrically controlled actuator (not shown) and / or by a sealed manually controllable device which can be operated from the outside and extends into the main body housing 100, for example a manually operable control actuator 450. For example, the manually operable control actuator 450 comprises mechanical adjusting means, for example a screw, a clamp, a slider, a valve, or the like, or electrical adjusting means, for example a potentiometer, a switch, an electrically or magnetically activatable contact / measuring point, or the like.

[0208] The interface 460 can be a wired interface on the fishing lure 1 with sealable contacts, for example a USB interface or an RS232 interface or another proprietary interface, or a wireless interface in the fishing lure 1, for example a Bluetooth interface or a WiFi interface. The angler 2 can program the electronic control unit 410 using a computer, for example a stationary computer, a portable computer, a tablet or a smartphone. Preferably, the computer has a further interface to connect to a remote computer or the internet in order to be able to download ready-made programs or updates therefrom to program the electronic control unit 410 of the fishing lure 1.

[0209] The self-moving fishing lure 1 comprises at least one fishing hook 110 for hooking a prey fish on the fishing lure 1 in case the prey fish successfully bites the hook. Preferably, the fishing hook 110 is elastically connected to the fastening means 130 by a fishing hook reinforcement 111 in order to ensure a very firm mechanical connection between the to-be-caught prey fish and the angler 2 by the fishing line 10 connected to the angler 2 even in the case of violent activity and to enable the angler 2 to retrieve the catch.

[0210] The optionally arranged artificial swim bladder 440 serves to position the float center 200 (see Figure 2 ) within the main body housing 100 of the fishing lure 1. In order to move the float center 200, the volume of the artificial swim bladder 440 and / or the position of the float center 200 within the main body housing 100 can be changed manually, optionally by an electrically controlled actuator (not shown) or by the manually operable control actuator 450. Moving the float center 200 relative to the center of gravity 210 changes the position of the vertical axis 250 relative to the direction of movement y and thus the static position (adjustment) or angle of the vertical axis 250 of the fishing lure 1, for example relative to the vertical z-direction of the surrounding water body 3. Optionally, the floating attitude generates or supplements the buoyancy alternatively or additionally. In the case of a dynamic movement v of the fishing lure 1 relative to the surrounding water body 3, it can be determined together with one or more flow bodies, for example one or more elevators 121, 122 (see Figure 3 and Figure 4 ), in which the self-moving artificial fishing lure 1 swims in the vertical z-direction.

[0211] Optionally, a pressure sensor (not shown) for detecting the current depth hydrostatic pressure can be arranged at the electronic control unit 410, wherein in combination with the electronic control unit 410, the means for controlling the depth are controllable to maintain a certain predetermined depth according to a program or in response to a decoded message from the angler.

[0212] Optionally, means (not shown) for delivering acoustic and / or visual and / or taste lures to attract prey fish can be provided on the electronic control unit 410 and can optionally be activated and deactivated by the control unit 410. The means for delivering acoustic lures can include electromechanical vibrators that deliver vibrations into the surrounding water, in particular simulating a sick bait fish. The means for delivering visual lures can include, for example, flashing or continuously signaling light emitting diodes that emit a lure visual signal into the surrounding water. The means for delivering taste lures can include manually fillable lure tanks in the self-moving artificial bait fish that can be emptied by a control signal or include permanently emptyable lure tanks that deliver taste lure substances, for example, body fluids or aromatic substances simulating a sick or dead fish bait into the surrounding water.

[0213] Preferably, at least one positioning means (not shown) is provided in the self-moving fish bait 1. In particular, a GPS positioning means and / or an acoustic positioning means, for example, an ultrasonic transmitter, and / or an optical positioning means, for example, a flashing light emitting diode, are provided as positioning means. The positioning means is preferably used to find a lost fish bait 1.

[0214] Figure 5 A main arrangement of the drive means in the fish bait is shown in a top view in a cross-sectional view A-B. Here, due to the electromagnetic force effect, the electromagnet 300 within the fish bait body 102, 102' causes the oscillation of the permanent magnet transversely to the longitudinal axis Y of the fish bait body. This oscillation is transmitted via the swing lever 312 and the drive bearing point 311 to the tail fin transition area 101 and the tail fin 103. As a result, the swing lever 312, the tail fin transition area 101 and the tail fin 103 are directly arranged to oscillate transversely to the longitudinal axis Y of the fish bait body. Thus, the natural movement generated by the fish bait 1 is free from any unnatural mechanical vibrations caused by contact, rotational movement, commutation, bearings or gearboxes or eccentric mechanisms of the drive motor, etc. When the tail fin 103 moves in the surrounding water 3, the propeller is essentially noiseless and emits vibrations that are the same as when a live fish in its natural movement escapes or moves from being motionless in the water 3 to being injured or sick.

[0215] Figure 6a is a cross-sectional view through the fish bait body shell and the fish bait body in section E-F described for the first alternative embodiment. The section E-F shows a cross-section through the cylindrical excitation coil 301 and the ferromagnetic core 302, which are located in the center of the circular tube of the fish bait body 102.

[0216] Figure 6b is a longitudinal sectional view of a fishing lure body housing and a fishing lure body according to a first alternative embodiment. The body housing 100 of the fishing lure 1 accommodates the fishing lure body 102 therein along a longitudinal axis Y of the fishing lure body. The tubular fishing lure body 102 is watertightly sealed at its head end by a fishing lure body front outer wall 105 and at its tail end by a fishing lure body rear outer wall 104. Preferably, the fishing lure body 102 can be removed from or opened within the body housing 100, for example, by separating the body housing 100 at its front end. By removing the fishing lure body front outer wall 105, the fishing lure body 102 can be opened for replacing the power supply 420 or accessing an interface 460' of the electronic control unit 410 provided within the fishing lure body 102 through which the electronic control unit 410 is controllable and / or programmable. For example, a controller device comprises a manually operable control element 422 which is accessible to a user when the fishing lure body 102 is opened or which is operable from outside the fishing lure body 102 when watertightly sealed. The manually operable control element 422 comprises, for example, an on / off switch which can be used to generate or cut off the electric power from the electromagnetic power supply 420 to the electrical components of the electromagnetic wobbling drive. The manually operable control element 422 can also allow, for example, a step switch or a regulation knob or other control for manually changing control parameters of the controller of the electromechanical wobbling drive, for example, frequency, pause time, etc. The fishing lure body 102 accommodates the electronic control unit 410 and its electrical components, the power supply 420 and the field coil 301 and its ferromagnetic material core 302. In this embodiment, the rear end of the ferromagnetic material core 302 passes through the fishing lure body rear outer wall 104 in a watertight manner, forming the rear end of the electromagnet 300. Alternatively, the rear end of the ferromagnetic material core 302 can be provided within the fishing lure body 102.

[0217] In this embodiment, the permanent magnet 313 is located outside the fishing lure body 102 at a distance h from the electromagnet 300 comprising the ferromagnetic material core 302 of the field coil 301. In this case, the swing lever 312 is movably supported outside the fishing lure body 102 and moved back and forth non-contactingly by the magnetic field of the field coil 301. The swing lever transitions into a tail fin (not shown) which is provided as a mechanical wobbling motion. In this example, the permanent magnet 313 consists of two stacked cubic permanent magnets which form a common pole axis P2 transverse to the longitudinal axis Y of the fishing lure body. The permanent magnet 313 is connected with the swing lever 312 of the permanent magnet wobbling actuator located outside the fishing lure body 102. Alternatively, the permanent magnet 313 can be integrated into the body housing 100 of the artificial fishing lure 1 in the tail fin region or into the tail fin region of the dead fishing lure 1.

[0218] In these embodiments, the wobble bearing 311 is located outside the lure body 102 in the main body housing 100 of the artificial lure 1 or the natural dead bait lure 1. The wobble bearing 314 of the artificial lure 1 preferably comprises an elastic material, such as a plastic, in particular an elastomer, rubber or silicone, which specifies an elastic modulus in the range of 0.5 MPa to 100 MPa, or a Shore A hardness in the range of 50 to 95 Shore 00 or 10 Shore A to 90 Shore A, preferably in the range of 10 Shore A to 60 Shore A, measured according to DIN ISO 7619-1.

[0219] Figure 6c is a detail view of the cross section G-H, is a cross-sectional view of the electromagnet and the wobble actuator component of the first alternative embodiment. Shown in plan view is the electromagnet 300, comprising the field coil 301 and the ferromagnetic material core 302.

[0220] The first pole axis P1 of the electromagnet is parallel to the longitudinal axis Y of the lure body. The wobble bearing 311 is arranged at a distance L from the electromagnet 300. The wobble actuator comprising the permanent magnet 313 and the swing lever 312 is shown in its zero position, in which no field current ie is flowing through the field coil 301. The swing lever 312 is moved into the zero position by the elastic return element 314. The pole axis P2 is perpendicular to the longitudinal axis Y of the lure body. In the zero position, there is an air gap ho between the permanent magnet 313 and the ferromagnetic material core 302 of the electromagnet 300. When the swing lever 312 is rotated around the wobble bearing 311, the edges of the cuboid formed by the two cuboid-shaped permanent magnets extend along the dashed lines at a distance Rp from the wobble bearing. These edges thus have the smallest air gap he.

[0221] Figure 6a is a cross-sectional view of the cross section E-F through the lure body housing and the lure body of the second alternative embodiment. The cross section E-F shows a cross section through the cylindrical field coil 301 and the ferromagnetic core 302 and the ferromagnetic material pole shoes or yoke 303, which are arranged within the circular tube of the lure body 102.

[0222] Figure 6bis a longitudinal sectional view of a second alternative embodiment of a fishing lure body housing and a fishing lure body. The body housing 100 of the fishing lure 1 accommodates the fishing lure body 102 therein along the fishing lure body longitudinal axis Y. The tubular fishing lure body 102 is watertightly sealed at its head end by a fishing lure body front outer wall 105 and at its tail end by a fishing lure body rear outer wall 104. Preferably, the fishing lure body 102 can be removed from or opened within the body housing 100, for example, by separating the body housing 100 at its front end. By removing the fishing lure body front outer wall 105, the fishing lure body 102 can be opened to replace the power source 420 or to access an interface 460' to the electronic control unit 410 provided within the fishing lure body 102 through which the electronic control unit 410 is controllable and / or programmable or the power source 410 is rechargeable. A controller device comprises, for example, a manually operable control element 422 which is accessible to a user when the fishing lure body 102 is opened or which is operable from outside the fishing lure body 102 when watertightly sealed. The manually operable control element 422 comprises, for example, an on / off switch which can be used to generate or cut off the electrical power from the electromagnetic power source 420 to the electrical components of the electromagnetic wobble drive. The manually operable control element 422 can also allow, for example, a step switch or a regulation knob or other control for manually changing control parameters of the controller of the electromechanical wobble drive, for example, frequency, pause time, etc. The fishing lure body 102 accommodates the electronic control unit 410 and its electrical components, the power source 420 and the field coil 301 and its ferromagnetic material core 302 as well as the electromagnetic material pole shoe or yoke 303. In this embodiment, the rear end of the ferromagnetic material core 302 passes through the fishing lure body rear outer wall 104 in a watertight manner, forming the rear end of the electromagnet 300. Alternatively, the rear end of the ferromagnetic material core 302 is formed in the fishing lure body rear outer wall 104 in a watertight manner and forms the rear end of the electromagnet 300.

[0223] In this embodiment, the permanent magnet 313 is located outside the fishing lure body 102 at a distance h from the electromagnet 300 comprising the ferromagnetic material core 302 of the field coil 301. In this case, the swing lever 312 is movably supported outside the fishing lure body 102 and moved back and forth non-contactingly by the magnetic field of the field coil 301. The swing lever transitions into a tail fin (not shown) which is provided as a mechanical wobbling motion. In this example, the permanent magnet 313 consists of two stacked cubic permanent magnets which form a common pole axis P2 transverse to the fishing lure body longitudinal axis Y. The permanent magnet 313 is connected with the swing lever 312 of the permanent magnet wobble actuator located outside the fishing lure body 102. Alternatively, the permanent magnet 313 can be integrated into the body housing 100 of the artificial fishing lure 1 in the tail fin region or into the tail fin region of the dead fishing lure 1.

[0224] In these embodiments, the wobble bearing 311 is located outside the lure body 102 in the main body housing 100 of the artificial lure 1 or the natural dead bait lure 1. The wobble bearing 314 of the artificial lure 1 preferably comprises an elastic material, for example a plastic, in particular an elastomer, rubber or silicone, which specifies an elastic modulus in the range of 0.5 MPa to 100 MPa, or a Shore A hardness in the range of 50 to 95 Shore 00 or 10 Shore A to 90 Shore A, preferably in the range of 10 Shore A to 60 Shore A, measured according to DIN ISO 7619-1.

[0225] Figure 6c is a detail view of the cross section G-H, is a cross-sectional view of the electromagnet and the wobble actuator components of the embodiment of the second alternative embodiment. Shown in plan view is the electromagnet 300 comprising the field coil 301 and the ferromagnetic material core 302.

[0226] The first pole axis P1 is guided tail-side to the rear by at least one ferromagnetic material pole shoe or yoke 303 and forms a further first pole axis P1' of the ferromagnetic material pole shoe or yoke 303, which preferably has an angle to the lure body longitudinal axis Y in the range of 0° + / - 30°, preferably 0° + / - 10°, in particular 0° + / - 5° and thus is essentially parallel to the lure body longitudinal axis Y.

[0227] The further first pole axis P1' of the electromagnet is parallel to the longitudinal axis Y of the lure body. The wobble bearing 311 is arranged at a distance L from the electromagnet 300. The wobble actuator comprising the permanent magnet 313 and the swing lever 312 is shown in its zero position, in which no field current ie flows through the field coil 301. The swing lever 312 is moved into the zero position by the elastic return element 314. The pole axis P2 is perpendicular to the lure body longitudinal axis Y. In the zero position, there is an air gap ho between the permanent magnet 313 and the ferromagnetic material core 302 of the electromagnet 300. When the swing lever 312 rotates around the wobble bearing 311, the edges of the cuboid formed by the two cuboid-shaped permanent magnets extend along the dashed line at a distance Rp from the wobble bearing. These edges thus have a minimum air gap he.

[0228] Figure 7a The components of the electromagnet and the wobble actuator of the embodiment of the first embodiment are shown schematically in the zero position. Shown in plan view is the electromagnet 300 comprising the field coil 301 and the ferromagnetic material core 302.

[0229] The polar axis P1 is parallel to the longitudinal axis Y of the lure body. A oscillating bearing 311 is positioned at a distance L from the electromagnet 300. The oscillating actuator, including a permanent magnet 313 and a swivel 312, is shown in its zero position, where no excitation current ie flows through the excitation coil 301. The connection between the power supply 420 and the excitation coil 301 is disconnected via a manually operable control element 422. In this embodiment, the swivel 312 is moved to the zero position by an optional resilient reset element 314. In this position, the restoring force Fr is 0. The polar axis P2 is perpendicular to the longitudinal axis Y of the lure body. In the zero position, there is an air gap h0 between the permanent magnet 313 and the ferromagnetic core 302 of the electromagnet 300. The reset element 314 can be optionally omitted because, in the case of continuous or sufficiently long reverse excitation of the electromagnet 300 within a deflection cycle, the restoring force is provided by the reverse excitation and / or by the force of the surrounding water 3 flowing through the fin.

[0230] At the zero position, the distance between the magnetic core of permanent magnet 313 and the ferromagnetic core 302 of excitation coil 301 is h0, and it is aligned with the polar axis P1. In this position, permanent magnet 313 applies a minimum force Fm0 to the ferromagnetic core 302 of electromagnetic excitation coil 301. The distance between the ferromagnetic core 302 and the magnetic core is h0. The magnetic core is the magnetic neutral region of the permanent magnet and is located on one side of the permanent magnet. The oscillating actuator is in an unstable to slightly stable equilibrium position and can be deflected in the positive direction sm+ by a weak positive electromagnetic pulse or in the negative direction sm- by a weak negative electromagnetic pulse. In this position, the deflection sm of the pendulum 312 is 0.

[0231] Figure 7b The components of the electromagnet and oscillating actuator described in the first embodiment are schematically shown in a partially positive deflection state.

[0232] The circuit between power supply 420 and excitation coil 301 is closed. Electromagnet 300 is driven by alternating polarities (see...). Figure 7b and Figure 7c This includes the electric bipolar AC voltage, which is the driving voltage ue at the excitation coil 301, and the bipolar flowing AC current, which is the excitation current ie of the excitation coil 301 passing through the electromagnet 300.

[0233] An excitation voltage ue is applied positively to the excitation coil 301, and a positive excitation current ie flows through the excitation coil 301. Therefore, a south pole S is formed at the rear end of the ferromagnetic core 302 along the first polar axis P1, and a north pole N is formed at the front end of the ferromagnetic core 302. The polarity is chosen as an example, and opposite polarities are also possible. At the position shown for the lever 312, the latter has already departed from the zero position in the positive sm direction, reaching a deflection sm, but has not yet reached its positive endpoint position smE+.

[0234] When the swing driver moves towards its respective end position smE, the effective air gap hi between the electromagnet 300 and the permanent magnet 313 dynamically decreases with the deflection sm of the swing lever 312 after leaving the zero position. The magnetic force fm of the permanent magnet 313 is concentrated at the edge of the permanent magnet 313 forming the smallest air gap hi. With decreasing air gap hi, the magnetic force component increases and is relatively smallest at the end position smE and the magnetic force effect Fm reaches a relatively maximum value. Until the end position is reached, the magnetic force component forms a force component Fmd acting perpendicularly on the swing lever. This results in a movement magnetic moment Mm acting on the swing lever at a distance Rp.

[0235] When the respective end position smE is exceeded, the effective air gap h increases again, the magnetic force effect Fm on the permanent swing actuator decreases, the direction of the force vector Fmd is reversed, resulting in the swing being guided back to the end position smE, where the magnetic force effect Fm has a relative maximum. The distance h and the magnetic force effect Fm are relative, because in different embodiments the swing radius and the distance of the swing pivot from the electromagnet core can be chosen differently from the electromagnet, respectively.

[0236] With increasing deflection sm, the restoring force Fr of the elastic return element 314 also increases and generates a comparatively small counter-torque to the movement magnetic moment Mm.

[0237] Figure 7c The components of the electromagnet and the swing actuator described in the embodiments of the first embodiment in the deflected positive end position are shown schematically.

[0238] Once deflected, the magnetic field of the permanent magnet 313 starts to exert its force effect Fm on the magnetic field of the ferromagnetic material core 302 of the electromagnetic field coil 301 and causes the deflection of the swing driver to increase until the latter reaches the positive end position smE+ or the negative end position smE-, at which the air gap hE reaches a minimum value and thus the force effect Fm of the magnetic field of the permanent magnet 313 on the magnetic field of the ferromagnetic material core 302 of the electromagnetic field coil 301 reaches a maximum value. Depending on the damping effect of the optional elastic return element 314 of the swing bearing 311 and / or the flow forces acting on the tail fin when used in a body of water 3, a non-periodic transient or damped transient process follows according to the e-function, so that the end position of the swing, e.g. the positive end position smE+ is reached (see Figure 1 ).

[0239] In this case, in addition to the restoring force of the tail fin in a stationary or flowing body of water 3, a velocity-dependent damping generated by the relative movement of the tail fin with the surrounding body of water and / or a restoring force Fr generated by the elastic return element, suppresses the swing amplitude and / or restores the swing to its zero position if the field excitation effect is significant, thus supporting the magnetic pole reversal process.

[0240] Figure 7dThe components of the electromagnetic body and the swing actuator described in the embodiments of the first embodiment are schematically shown in a deflected negative end position.

[0241] From Figure 7c From the position shown, the swing driver is reversed by reversing the polarity of the voltage ue applied to the field winding 301 of the electromagnetic body 300, so that an opposite current ie flows through the field winding 301 of the electromagnetic body 300. The oppositely polarized magnetic force field of the electromagnetic body 300 thus generated is opposite to the magnetic force field of the permanent magnet 313 and supports the restoring force Fr caused by the elastic return element 314, so that the swing lever 312 is accelerated in the direction of the opposite end position. In this process, the swing lever 312 is deflected in the opposite direction beyond the zero position under the influence of the force fields of the electromagnetic body 300 and the permanent magnet. In this process, the magnetic field Fm of the permanent magnet 313 again begins to exert its force effect on the magnetic field of the ferromagnetic material core 302 and causes an increase in the deflection of the swing lever 312 until the latter reaches the negative end position smE- at which the air gap hE reaches a minimum and thus the force effect Fm of the magnetic field of the permanent magnet 313 on the magnetic field of the ferromagnetic material core 302 reaches a maximum. Depending on the damping effect of the elastic return element 314 and / or the flow forces acting on the tail fin when used in a body of water 3, a non-periodic transient or damped transient process follows in a damped manner according to an e-function, so that the end position of the swing lever 312 is reached.

[0242] Figure 8a The course of the dynamic air gap h as a function of the deflection sm is shown. In the embodiments described above, the air gap h has a minimum at the end position smE of the swing lever 312 and a maximum at the zero position sm0 of the swing lever 312.

[0243] The air gap h is the shortest distance between the magnetic poles of the permanent magnet 313 of the permanent-magnetic swing actuator and the electromagnetic body 300 of the electromagnetic swing driver. The dynamic air gap h is the air gap h formed in relation to the deflection of the permanent-magnetic swing actuator from its rest position. The air gap h preferably varies between 20 mm and 0.05 mm, in particular between 5 mm and 0.05 mm, and preferably between 2 mm and 5 mm.

[0244] Figure 8b The course of the magnetic force effect Fm as a function of the deflection sm is shown. The magnetic force effect Fm has a minimum at the maximum air gap h0 at the zero position of the swing lever 312 and a maximum at the minimum air gap at the respective end position smE of the swing lever 312. In coordination with the swing radius, the elastic and dynamic restoring moment, the number of windings N and the size of the field current ie, the smaller the air gap h, the greater the movement moment of the permanent-magnetic swing actuator and thus of the fish bait driver that can be achieved.

[0245] Figure 9aThe movement magnetic moment Mm is shown as a function of the swing lever deflection sm. With increasing deflection sm of the swing lever in the positive or negative direction, the air gap decreases (see Figure 8a ). With decreasing air gap hi, the magnetic force component Fm ~ 1 / h hyperbolic increases and reaches a relative maximum at the end position smE. Until the end position is reached, the magnetic force component forms a force component Fmd acting perpendicularly on the swing lever. This results in a movement magnetic moment Mm acting on the swing lever at a distance Rp. The movement magnetic moment reaches a relative maximum MmE at each end position. When the respective end position smE is exceeded, the effective air gap h increases again, the magnetic force effect Fm on the swing lever 312 decreases, the direction of the force vector Fmd is reversed, resulting in the swing being guided back to the end position smE, where the magnetic force effect Fm has a relative maximum. The relationship of Mm and deflection sm has one pole in each end position smE of the swing lever 312, which stabilizes the swing lever 312 in the end position smE until the end smE is reversed by the electromagnet. Since the attractive force between the permanent magnet 313 and the ferromagnetic material pole shoe or magnetic yoke or ferromagnetic material core 302 reaches a stable critical maximum MmE at the end position, this results in a maximum force effect Fm and no need for a stop, thus enabling a noise-free limiting of the deflection sm of the swing lever 312. Elastic stops can optionally be provided to limit the swing amplitude.

[0246] Figure 9b The movement magnetic moment Mm is shown as a function of the swing lever deflection sm and the control range required for commutation. By flowing a counter current ie through the field coil 301 of the electromagnet 300, the polarity of the voltage ue applied to the field coil 301 of the electromagnet 300 is reversed, thus reversing the swing lever 312 of the swing drive (see Figure 7d ). The oppositely polarized magnetic force field of the electromagnet 300 thus generated opposes the magnetic force field of the permanent magnet 313 and supports the restoring force Fr caused by the elastic restoring element 314, accelerating the swing lever 312 in the direction of the opposite end position.

[0247] To initiate the reversal of the swing lever 312, the restoring movement magnetic moment Mm applied for this purpose must overcome the force effect caused by the permanent magnet 313 when attracted to the ferromagnetic material core 302 and / or the ferromagnetic material pole shoe or magnetic yoke 303 and the resulting movement moment Mm. In this respect, the required restoring moment MmR is assisted by the permanent elastic restoring moment caused by the elastic restoring means and the restoring moment applied to the tail fin by the surrounding water body 3. The restoring movement magnetic moment MmR can be reduced by the amount of these additional restoring moments. Furthermore, the reversal advantageously requires reversal of the excitation of the electromagnet 300 only until the swing lever reaches a range in which the permanent elastic restoring moment alone is sufficient to overcome the remaining attractive force moment of the permanent magnet 313. The accelerated mass of the permanent magnet 313 advantageously imparts sufficient kinetic energy on the swing lever 312 to move it further beyond the zero position to the opposite end position, where it is picked up and stabilized by the oppositely excited electromagnet that is again activated.

[0248] During this process, the swing lever 312 is deflected in the opposite direction beyond the zero position under the influence of the force fields of the electromagnet 300 and the permanent magnet.

[0249] For the reversal, the acceleration in the direction from one end position to the other end position is preferably initiated by a current pulse with a defined duty cycle compared to the driving frequency or the period of the swing drive. The input current pulse ie for the excitation of the excitation coil 301 preferably has a smaller time integral compared to the case of symmetrical or asymmetrical control. The integral of the current ie over time is the charge taken from the power source 420 for the activation. With the same amount of charge, by reducing the pulse width of the excitation current ie, the amplitude of the current pulse ie can be increased, thus increasing the restoring torque, which increases the movement torque of the thruster, or the amount of charge taken from the power source 420 can be reduced with the same movement torque, so that the operating time of a specific power source 420 can be extended or a smaller power source 420 can be used with comparable operating times.

[0250] It is advantageous to optionally arrange a sensor for detecting the current position of the swing lever 312 and transmitting this information to the electronic control unit 410 (see Figure 4 ). The electronic control unit 410 determines from the current position of the swing lever 312 whether excitation of the electromagnet 300 is required for the reversal, whether the excitation current ie is required, or whether the excitation current ie can be reduced or switched off without hindering or supporting the reversal process.

[0251] Figure 10 The main relationship between the size of the magnetic force and the size of the air gap width is shown. The diagram shows that there is essentially a hyperbolic relationship between the size of the magnetic force effect and the size of the air gap width, which is derived from the magnetic force relationship in the air gap according to the following equation

[0252] Fm ~ K * (ie * N / h) 2 ,

[0253] The magnetic force Fm increases in a quadratic hyperbolic manner as the air gap h decreases.

[0254] Due to the advantageous arrangement of the electromagnet 300 (see Figures 4 to 7d and Figure 11 ), on the one hand, the high magnetic holding force of the permanent magnet 313 is used to generate a high magnetic torque Mm, which, in cooperation with the electromagnetic force field effect of the electromagnet 300, attracts during the deflection sm and compensates during the reversal, in order to achieve the magnetic field compensation required for the reversal with as low an excitation current ie as possible and thus to initiate the energy-efficient reversal of the swing actuator in an energy-saving manner with respect to the energy source 420 carried.

[0255] Figure 11The arrangement of an electromagnetic wobble drive within the bait body is shown. A permanent magnet 313 is arranged within the bait body 102. The bait body 102 is surrounded caudally by the body cavity 100 of the artificial bait 1 or dead natural bait 1. In this case, a wobble lever 312 is mounted on the rear outer wall 104 within the bait body 102 and moved back and forth non-contactingly by the magnetic field of the field coil 301. The wobble actuator formed thereby is movable out of the rear end of the bait body 102, sealed against the ingress of water, and into the tail fin, which is arranged for mechanical oscillation movement transverse to the longitudinal axis Y of the bait body. The passage of the wobble lever 312 through the rear wall 104 of the bait body preferably comprises a permanent elastic return element 314, further preferably a permanent elastic sealing device made of, for example, rubber or silicone or another elastomer, and preferably forms a wobble bearing 311 about which the wobble lever 312 of the wobble actuator rotates. The wobble bearing 311 and the sealing provided by the permanent elastic return element 314 preferably comprise an elastic material, for example a plastic, in particular an elastomer, rubber or silicone, which has a modulus of elasticity of 0.5 MPa to 100 MPa or a Shore A hardness of 50 to 95 Shore 00 or 10 Shore A to 90 Shore A, preferably 10 Shore A to 60 Shore A, measured in accordance with DIN ISO 7619-1. In the case of a dead natural bait 1, the body shell 100 can completely cover the wobble actuator, so that the wobble actuator causes the bait body and / or its tail fin 103 to move transversely.

[0256] Figure 12 The electromagnet and wobble actuator components of the embodiment of the first embodiment with a second pole axis P2 arranged at 0° + / - 40° with respect to the longitudinal axis of the bait body are shown.

[0257] Thus, the field coil 301 is arranged with the first pole axis P1 at 0° + / - 40° with respect to the lure body longitudinal axis Y and the permanent magnet 313 is arranged with the second pole axis P2 at 0° + / - 40° with respect to the lure body longitudinal axis Y. A bipolar control is preferred. Alternatively, in this embodiment, a unipolar actuation can optionally be provided, but this is not the preferred way. In this embodiment, the zero position is located in one of the end positions smE and is transferred from a possible previous deflection to the zero position by the elastic return element 314 when the electromagnet 300 is not excited, i.e. when no electric current ie is flowing through the field coil 301 of the electromagnet 300. The elastic return element 314 comprises for example an elastomer, rubber or silicone or one or more permanent elastic springs made of metal or plastic. In the case of bipolar control, the permanent magnet 313 is drawn to the magnetic pole of the electromagnet 300 when the polarity of the excitation current ie in the electromagnet 300 is opposite to the polarity of the permanent magnet 313, resulting in the swing lever 312 leaving its zero position. The provision of a field coil with a ferromagnetic core 302 is particularly advantageous because the permanent magnet 313 exerts an additional magnetic force Fm on the ferromagnetic core 302 in the air gap h due to the permanent magnetic attraction. Conversely, when the excitation current ie in the electromagnet 300 is homopolar with respect to the polarity of the permanent magnet 313, the permanent magnet 313 is repelled from the magnetic pole of the electromagnet 300, resulting in the swing lever 312 returning to its zero position. If the field coil 301 is arranged with a ferromagnetic core 302, the additional magnetic force exerted by the permanent magnet 313 on the ferromagnetic core in the air gap has to be overcome. In order to achieve a symmetrical movement of the tail fin 103 with respect to the lure body longitudinal axis Y, in the present embodiment, a lateral offset arrangement of the swing actuator and / or the electromagnet 300 with respect to the swing actuator longitudinal axis Y is advantageous.

[0258] Figure 13 A cross-sectional view of a lure drive with an electromagnet 300 comprising a field coil 301 with a first pole axis P1 and a swing actuator comprising a permanent magnet 313 with a second pole axis P2 and a swing lever 312, wherein the permanent magnet 313 is movable transverse to the lure body longitudinal axis Y due to the electromagnetic force field of the electromagnet 300, wherein the field coil 301 is arranged with the first pole axis P1 at 0° + / - 30° with respect to the lure body longitudinal axis Y, an E-shaped pole shoe or yoke 303 of ferromagnetic material, wherein a central core 302 of ferromagnetic material is arranged within the field coil 301 and on the ferromagnetic material outside the field coil 301 from a first pole end 304 of the central core 302 of ferromagnetic material to a second pole end 305 of the central core 302 of ferromagnetic material, forming the pole shoe or yoke 303 of ferromagnetic material with an air gap to the central core 302 of ferromagnetic material at the second pole end 305 of the central core 302 of ferromagnetic material, wherein the permanent magnet 313 is movably arranged such that a projection of the field coil 301 onto the first pole axis P1 and a projection of the permanent magnet 313 onto the second pole axis P2 intersect at a defined angle in at least one position.

[0259] In each case, the magnetic core 303 comprising the ferromagnetic material central core 302 and at least one lateral ferromagnetic material pole shoe or yoke can be formed as a flat E-shaped or U-shaped magnetic core or rotationally symmetrical cylindrical pot-shaped or cylindrical pot-shaped pole shoe or yoke 303 of ferromagnetic material cut out at the ends, for example as shown in Figure 14a and Figure 14b .

[0260] Figure 14a and Figure 14b show embodiments with partial pot-shaped pole shoes or yokes 303 made of ferromagnetic material, each figure being a cross-sectional view, Figure 14a shows an embodiment in which the central core 302 and the lateral ends of the ferromagnetic material pole shoe or yoke 303 are designed in such a way that the permanent magnet 313, during its rotation in the swing bearing 311 about the swing bearing rotation axis 311’, passes through the circular arc-shaped distance lines ho and he, so that in the respective end position the permanent magnet has the smallest distance to the ferromagnetic material central core 302 and to the ferromagnetic material pole shoe or yoke 303, respectively, and exerts the highest magnetic attraction at this position. Advantageously, even without optionally possible mechanical stops, the permanent magnet remains in this position until the reversal process (see Figure 9a ). The thruster can thus be operated with particularly low noise.

[0261] Figure 14b The ends of the ferromagnetic material central core 302 and the ends of the ferromagnetic material pole shoe or yoke 303 forming the air gap are shown in cross-sectional view. The width of the cross-section preferably corresponds to the shape of the magnetically effective edge of the permanent magnet.

[0262] The ends of the ferromagnetic material pot-shaped pole shoe or yoke 303 can optionally be straight, for example corresponding to the straight edges of a cubic or cuboid permanent magnet 313. In the case of a bar-shaped or cylindrical permanent magnet, each end can be arc-shaped, so that in each of the above cases a uniform air gap as possible is formed between the edge of the permanent magnet 313 and the ferromagnetic material central core 302 and the ferromagnetic material pole shoe or yoke 303. On the one hand, this enables a high force effect of the permanent magnet 313 in the end position, on the other hand, a high magnetic flux density can be provided for the reversal of the swing lever 312.

[0263] Figure 15is an example of an assembly with an external line guide, a line stop. With increasing mass of the components, for example the excitation coil 301 with ferromagnetic components and the power supply of the bait 1, the downward gravity on the bait 1 increases. In order to compensate this during the submersion of the bait 1 in the surrounding water body 3 and to keep the bait 1 in a stable position in the surrounding water body 3, preferably on the bait body 102, on the one hand a float 150 statically determines the inclination of the bait body 102 and its submersion depth in the surrounding water body 3 and on the other hand indicates the current position of the bait 1 relative to the surface of the surrounding water body 3 and the angler. In the shown embodiment, an adjustable and lockable line stop 138 on the fishing line 10 is connected on the fishing line 10. The fishing line 10 is looped from behind through a rear second connection device 132, which provides a rear second offset point 142. The fishing line 10 is further looped through a front first connection device 131, which provides a front first offset point 141. From there, the fishing line 10 is further guided to the float 150, where it is connected below the float 150.

[0264] Due to gravity, the bait 1 slides down in the surrounding water body 3 along the fishing line 10 first until it reaches the position of the line stop 138 at the rear second offset point 142 of the rear second connection device 132. The positive y-direction sum of the force components Fyv generated by the bait drive initially causes the bait 1 to leave this position again until the movement generated by the bait drive along a section of the fishing line 10 between the bait 1 and the float 150 moves the float 150, so that it is subjected to an upward force component balancing the downward gravity, pulls the line stop 138 back to the rear second offset point 142 of the rear second connection device 132 on the bait body 102 and stabilizes the position of the bait 1 on the fishing line 10 and thus the depth of the bait movement.
