3493271The present invention is related to an improved decoy to attract live birds, in accordance with the preamble of claims 1 and 2, and use of the same in accordance with claim 10.BackgroundArtificial decoys are often used to attract live birds or other game in hunting situations. These 5 decoys are made to be visually like live game. To increase the likeness, the decoys are often equipped with motion stakes that allow the decoys to exhibit motion patterns like those observed in live game on the ground. Decoy motion is usually generated by wind, so when there is little or no wind, there will be little or no decoy motion.In some kinds of game hunting, in particular waterfowl hunting (e.g. ducks and geese), many 10 decoys are used to emulate flocks on the ground. “Frozen” decoy flocks with no motion are often either ignored, or even avoided, by live waterfowl. Experienced birds will often recognize them as representing danger.Different brands of motorized motion decoys have been around for years. These solve the problem of no decoy motion without wind, but they have generally tended to be so expensive that 15 most hunters will only buy a few and place them in a larger flock of other, less expensive decoys.US 2019/335744 A1 (Rodriguez) describes a mounting method, system and apparatus enabling water-based decoys to be deployed on land. The decoy stand described consists of a decoy platform, a mount, and a pole, and may include a motion creating assembly. The optional motion creating assemblies are not described in any detail in the text, but the figures refer to them as 20 «propeller assembly» (Fig.12), «wobbler assembly» (Fig.13), and Fig.14 addresses «water-based decoys with keel».US 2008/0029659 (Weber) discloses a decoy stand enabling wind-driven walking or feeding decoy motion patterns. The summary section states that the decoy motion may also be activated by a motor, but it is not disclosed how such a motor driven motion mechanism could be constituted or 25 operated.US 4,893,428 (Gagnon) discloses a passive device allowing a decoy to self-align due to the external force of wind, i.e. passively. 3493272ObjectAn object of the present invention is to improve decoys of this type, to improve degree of attraction of flying live birds, during tagging, hunting, or gaming on the ground.The invention5 The object above is achieved by an improved decoy in accordance with the characterizing part of claims 1 and 2, and a use of the same in accordance with claim 10. Additional advantageous features appear from the independent claims.General descriptionThe invention presented here modifies only the motion stake and not the decoy. It aims to be 10 affordable to hunters in much larger numbers than existing motorized motion decoys, seeking to enable the motion behavior of the entire flock of birds to appear more realistic than if only a small number of the decoys in the flock exhibit any motion.The present invention primarily addresses bird hunting situations with little or no wind. Using one simple unified motion principle, it enables the emulation of several common motion patterns in 15 decoys that are often observed in flocks of real birds on the ground: Grazing: The decoy regularly dips its head towards the ground, emulating the motion where a bird is grazing on edible material in front of it. Wagging: The decoy wags from side to side, emulating the motion of a bird walking forward.  Scouting: The decoy rotates slowly back and forth in a horizontal rotation plane within a 20 limited sector, emulating a “watchdog” behavior where the bird turns around to watch out for potential dangers. Combinations of scouting and grazing, and combinations of scouting and wagging.Waterfowl decoys will, referring to their shape, often be made to be of three general kinds: Grazing birds (“grazers”), wagging birds (“waggers”), and scouting birds (“scouters”). Grazing 25 waterfowl decoys such as geese will typically be made with horizontal necks and head positions.Scouting and wagging decoys will be made with more upright necks. A scouter decoy will typically be made with a longer neck than a wagging decoy. The most natural motion pattern of grazing decoys will usually be combinations of grazing and scouting movements, and the most natural 3493273motion of wagging decoys will usually be combinations of wagging and scouting movements. Scouter decoys will usually only use scouting movements.In further details, the present invention is related to an improved decoy imitating live birds to attract flying live birds to the ground for hunting, gaming or tagging purposes, said decoy being 5 arranged to be deployed on the ground. The decoy is supported in a movable manner upon a stake, and exhibits a neck with a head and beak, a tail, and a body having a belly, wherein the drive means (300) is arranged to bring the decoy (100) into a motion, The stake is, at its lowermost end, arranged to be supported upon the ground or inserted partly into the ground, and at its uppermost end arranged to be inserted into the decoy, mutually pivotal, at a stake support point.10 In particular, the decoy is powered by a drive means connected to the stake and is releasably connected to the decoy at its belly side by at least one decoy connection located either:as a longitudinal decoy connection, located at the decoy front or the decoy rear viewed in the head-tail direction, to imitate a walking bird or a scouting bird, oras a lateral decoy connection, located at one of the decoy’s sides nearby its wing, to imitate a 15 grazing bird or a scouting bird.The stake can be split into an upper stake section and a lower stake section, interconnected by said drive means, arranged to bring the decoy into motion with respect to the stake.In one embodiment, the drive means comprises a drive motor powered by a battery providing current at a desired voltage and connected by a drive plate via a pin to a slider that exhibits a slit, a 20 stake connection and a decoy connection. The pin is fixedly connected eccentrically to the drive plate, e.g. a circular plate or a wheel plate, and accommodated within the slit. The drive means is arranged to force the slider to move in a desired pattern in a horizontal plane by the pin, driven by the drive motor.In another embodiment, the drive means comprises a drive motor powered by a battery providing 25 current at a desired voltage and connected by a drive plate via a pin to a slider exhibiting a slit), a stake connection and a decoy connection. The pin is fixedly connected eccentrically to the drive plate, e.g. a circular plate or a wheel plate, and accommodated within the stake connection. The stake is accommodated within the slit, and the drive means is arranged to force the slider to move in a desired pattern in a horizontal plane by the pin accommodated within the stake connection 30 and driven by the drive motor. 3493274The shape of slit can for example be rectangular, square, trapezoidal, triangular, oval, bananashaped, or S-shaped.Moreover, the battery voltage can be controllable by a timer, or a programmable logic circuit (PLS), to effect the desired motion pattern of the decoy. The battery voltage is alternatively 5 controllable by a remote control, to effect the desired motion pattern of the decoy. The drive motor can be provided in the form of a stepper motor or a servo motor.The decoy connection is advantageously a releasable connection between slider to an underside (belly) of the decoy, selected from the group consisting of, a screw, a Velcro, a magnet, and a pinrecess connection.10 With respect to the effect of the various embodiments of an improved decoy in real use in a field, several decoys, particularly in a real hunting situation, can for example be realized byplacing one or more leading groups of decoys moving in a pattern that appears to be grazing and scouting, andplacing one of more trailing groups of decoys a few meters behind said one or more leading 15 groups of grazing and scouting decoys, that appears to be walking and scouting in the directions of the leading groups of grazers.In this way, we have observed that flying live birds are incited to land on a free area between leading groups of grazing and scouting decoys, and trailing groups of wagging and scouting decoys, for thereby contributing to steering the flying live birds to land on the free area where the user 20 wants. For example, a hunter will to an increased degree be able to guide live birds to a limited area on the ground. This will for example simplify catching and tagging or hunting where the risk of wound is avoided.DrawingsThe invention is hereinafter described in further details with reference to illustrations, where 25 Fig.1 is a side view of a prior art bird decoy balancing on top of motion stake,Fig.2 illustrates a first embodiment of a drive means,Fig.3 illustrates a second embodiment of the drive means, 3493275Fig.4 illustrates a third embodiment of the drive means,Fig.5 illustrates a fourth embodiment of the drive means,Fig.6 is a schematic illustration like Fig.1, showing the present invention implemented at a prior art decoy, and5 Fig.7 is a schematic illustration of a decoy from below.Detailed descriptionIn the drawings, Fig.1 illustrates a decoy, here a goose, indicated generally with reference numeral 100. This is provided with a so-called basic Scotch yoke or stake 200 extending substantially vertically upwards from a support point in the ground (not shown) into a conically shaped cup 101 10 inserted upwards into the body of the decoy 100 extending from an opening in the abdomen of the decoy and narrowing up to an underside of the back of the decoy, thus defining a support point 102 for an upper end 203 of the stake 200. Accordingly, the decoy 100 rests upon the stake 200 in a manner known per se, free to rotate about a substantially vertical axis of the stake 200 and/or move in and out of an imaginary horizontal plane. In other words, this arrangement 15 enables conversion between rotational and reciprocating motion of the decoy with respect to the stake 200 and hence the ground to which it is fixed.Now with reference to Fig.6, which is a drawing like Fig.1, but where the stake 200 is provided with a drive means 300. Here, the stake or yoke 200 is split into an upper stake section 200a and a lower stake section 200b, interconnected by a yoke connector 202 which enables the upper and 20 lower stake sections 200a, 200b to move independently. The yoke connector 202 may be a sleeve with an upper open part arranged to accommodate the lower end of upper stake section 200a and support the latter therein. On the other hand, the yoke connector 202 can be formed in a similar manner to be supported by an upper end of the lower stake section 200b. The yoke connector 202 may be an independent item or may constitute a part of either the upper stake section 200a or the 25 lower stake section 200b. In general, the drive means 300 is attached to or is constituted by the lower stake section 200b in a fixed manner. The drive means is described in further details below. Now referring to Fig.2, a first embodiment of the drive means 300 is illustrated, in a plane view from above. In general, the drive means comprises a drive motor 310 (not evident in Fig.2, but shown in Fig.6), and a slider 320 (also indicated in Fig.6). The slider 320 is here illustrated as an 30 elongate structure having a first slider fixture 321 and a second slider fixture 322. First and second 3493276slider fixtures 321, 322 are arranged to be connected, indirectly, to the decoy 100 and to the stake 200, respectively. The different embodiments are illustrated in the following drawings and described below.Said first and second slider fixtures 321, 322 are advantageously formed as a lug or ring to 5 accommodate another part of the structure as described below.Slider 320 is arranged to move in a reciprocating manner as indicated by the double-headed arrows, in a substantially horizontal direction, driven by a drive plate, here illustrated in form of a rotary wheel 301, which in turn is connected to the drive motor 310 in a rotary manner in the horizontal plane.10 A substantially vertically extending connector pin 302 is affixed atop the rotary drive wheel 301 in an eccentric manner. Connector pin 302 is at its opposite end connected to a slider-drive wheel interconnecting means 323, allowing connector pin 302 to force slider 320 to move along its horizontal plane, but not in a fixed manner. Here, slider-drive wheel interconnecting means 323 is formed as an elongate recess 323 defining a confined open slit 323, arranged to accommodate 15 connector pin 302 attached eccentrically to drive wheel 301, wherein the connector pin 302 is arranged to move within slit 323 transforming movement to slider 320, and further to stake 200 and in the end to the decoy 100 to make the latter to move in a desired pattern (from side to side at low motor speeds).Fig.3 shows a modified Scotch yoke, with one end connected to the stake. In further detail, the 20 first slider fixture 321 (stake connection) is connected to the stake, here the upper stake section 200a. At the opposite end of slider 320, the second slider fixture 322 (decoy connection) is connected releasably to a second part (underside) of the decoy 100 (not illustrated), e.g., by a screw, Velcro, pin-recess connection, allowing movements imposed by a reciprocating slider 320 at its end exhibiting second slider fixture 322, to be transferred to decoy 100 and make the same 25 to move in the desired manner. The two arrows at the right-hand side of Fig. 3 illustrates a reciprocal movement in a substantially horizontal plane as outlined above. In this embodiment, connector pin 302 is arranged to move inside the space defined by the confined open slit 323. Fig.4 shows a modified Scotch yoke, with slit 323, including interconnected drive wheel 301 and attached drive motor 310, arranged at one end of slider 320. First slider fixture 321 (stake 30 connection) is arranged further along slider 320, mutually displaced from second slider fixture 322 (decoy connection) arranged at the opposite end of slider 320. Similar to the embodiment of Fig. 3, connector pin 302 is arranged to move inside the space defined by the confined open slit 323. 3493277Fig.5 is an illustration like Figs.3 and 4 but showing a different embodiment of a modified Scotch yoke, generating more complex motion. Here, the slit 323 of slider 320 is located between first slider fixture 321 (stake connection) arranged at one end of slider 320, and second slider fixture 322 (decoy connection) arranged at the opposite end of slider 320. Contrary to the embodiments 5 of Figs.3 and 4, confined open slit 323 accommodates stake or yoke 200, wherein connector pin 302 is accommodated within first slider fixture 321.Now back to Fig.6, a split stake embodiment is shown, where stake 200 is split into an upper stake section 200a and a lower stake section 200b, interconnected by a yoke connector 202 and provided with drive means to effect motion of decoy 100 via upper stake section 200a.10 Fig.7 illustrates schematically the underside or bellow side of a decoy 100. Outer extremities of the decoy body are illustrated at decoy wing side 104, decoy head 105 and decoy tail 106. The conically shaped cup 101 inserted into the body of the decoy 100 is illustrated in a (cross-) section. The first slider fixture (stake connection) is illustrated at reference numeral 321 at the left-hand side of the drawing. The second slider fixture 322 of the preceding drawings is here illustrated at 15 two alternative positions: a second slider fixture (longitudinal decoy connection) 322’ located at the decoy head 105, and a lateral second slider fixture (lateral decoy connection) 322’’ located at decoy wing side 104. It it emphasized that second slider fixture (longitudinal decoy connection) 322’ alternatively can be located at the decoy tail 106. Similarly, the second slider fixture (lateral decoy connection) 322’’ illustrated at the top of the drawing alternatively can be located at the 20 opposite wing side of decoy, in the drawing at the bottom of decoy 100.Still with reference to Fig.7, motion behavior can be described as follows:When the decoy end of the slider 320 is connected to the front 105 or back 106 of the decoy belly at decoy connection 322’, the generated motion will be «wagging or scouting», depending on motor rotation speed. Low voltage supply to drive motor 310 will effect a rotational movement of 25 the decoy 100 in the horizontal plane («scouting»), whereas increasing voltage supply to drive motor 310, decoy movement will change into «wagging».To change this into «grazing scouting» motion, release the slider attachment 322’ to the decoy, turn the decoy 90 degrees in the horizontal plane, and attach the slider to the alternative attachment point 322’’ at one of the decoy belly’s sides 104. Similar to the voltage control 30 described immediately above, low voltage supply to drive motor 310 will effect a rotational movement of the decoy 100 in the horizontal plane «scouting», whereas increasing voltage supply to drive motor 310, decoy movement will change into «grazing». 3493278Discussion of varying embodiments and decoy movementMotion decoys will typically balance on top of motion stakes. The lower end of the stake is vertically fixed in or upon the ground. The decoy is placed on top of the stake through an opening in the decoy belly in a cone-shaped cup as illustrated above. The top of the stake is fixed either 5 directly onto a balance point at the inside of the decoy back, or onto a similar balance point in the cup.The motion stake may be equipped with motion restriction mechanisms to disable certain kinds of unnatural motions, e.g. full 360° horizontal rotation around the stake, which may otherwise occur in strong winds.10 The basic motion generating mechanism, the Scotch yoke:The present invention is inspired by a classical mechanical principle for conversion of rotational motion to reciprocating motion. The rotational motion of, e.g. a wheel connected to the shaft of a small DC motor, is connected to the slider described above, via an eccentric pin. This is illustrated in Fig.2.15 The eccentric pin moves back and forth (vertically in the picture) inside the opening of the slider when the wheel rotates, without causing any motion of the slider - the vertical component of the eccentric pin motion is passivated, but when the position of the eccentric pin moves to the left or right (horizontally in the drawing) as the result of the wheel rotation, the slider will be pushed to the left or to the right. The two slider fixtures ensure that only right or left motion is possible for 20 this slider.A modified Scotch yoke mechanism for motion stake decoys:A variation of this configuration, known as the “Quick return mechanism”, is also used to generate linear reciprocating motion. A modification of this mechanism may also be used to generate reciprocating rotation within a circle sector: If the motor with its attached wheel is fixed on the 25 motion stake,and one end of the slider is connected to the motion stake, andthe opening of the slider is along the line between its two ends instead of orthogonal to it, then rotation of the wheel will cause a reciprocating sectorial rotating motion of the other end of the slider, as illustrated in Fig.3. If this other end of the slider is connected to the belly of the 3493279decoy, then rotation of the wheel will cause the decoy to rotate back and forth within the same sector. This is the typical rotational motion described earlier as “Scouting”. The rate of motion of the decoy will be proportional to the rotational motion of the DC motor shaft and the wheel. Several different realizations of such a modified Scotch yoke are conceivable. One of these is 5 illustrated in Fig. 4. This configuration will generate the same kind of sectorial reciprocating rotation motion as the one in Fig.3.Getting “Grazing” or “Wagging” or more complex motion from the modified Scotch yoke mechanism:The proposed modified Scotch yoke mechanism has been extensively experimented with, using 10 several different motors with a large range of rotational speeds, from less than 10 rpm to more than 100 rpm.A surprising observation was made during these experiments: Beyond a certain motor speed, the decoy motion pattern changes completely, from strictly back-and-forth rotation (“scouting” behavior) to pendulum motions orthogonal to the rotation plane, with the decoy balance point 15 (where the top of the stake meets the decoy back or the top of its cone) being the fixed point of the pendulum: If the decoy-side fixture of the slider is attached below the head or the tail of the decoy, then the pendulum motion will be side-to-side, emulating the wagging motion of walking birds beyond a critical motor rpm.20  If the decoy-side fixture of the slider is attached to the sides of the decoy (below one of the wings), then the pendulum motion will be front-to-back, emulating the characteristic head-dipping motion of grazing birds beyond a critical motor rpm.With respect to the above, reference is in particular made to Fig.7.The value of the critical motor rpm where the motion changes from rotational (low-rpm) to 25 pendulum (high-rpm) depends on both the decoy shape and the decoy weight, and it may thus vary among different decoy brands and models. There will also be a range of intermediate motor rpms (mid-rpm) where the motion is a more complex combination of rotational and pendulum motion. 34932710Combinations of rotation and pendulum motions may also be generated by use of alternative configurations of the modified Scotch yoke. One such example is illustrated in Fig. 5. This configuration will generate a combination of rotation and pendulum motion, even at low motor rpms. Additional motion variations, not illustrated here, may be generated using slider openings 5 with shapes departing from the linear/rectangular form, e.g. trapezoidal, triangular, oval, bananashaped, S-shaped, etc.Variety in individual decoy motions in a flock of decoys may be exploited to emulate the natural variation of motion of individual birds in a real bird flock. In addition to slider opening shape variations, such variety may be achieved by variations of the two fundamental parameters of this 10 invention: The drive motor rpm of individual decoys Attachment position of the decoy-end of the slider to the individual decoy belly.The attachment position will be determined upon decoy flock setup, but may be changed manually during hunting breaks, if so desired.15 The motor rpm of individual decoys may be fixed upon decoy flock setup: The motor rpm of any given motor will be a function of the voltage supplied to the motor, so a 3V battery supply (e.g.2 AA batteries in series) will generate a different motion than a 6V battery supply (e.g. 4 AA batteries in series). It may however also be modified in real time remotely, if desired, e.g. if one or more PWM (pulse width modulated) remote controls are used to control the rpms of the 20 respective drive motors in the decoy flock.The motion pattern of individual decoys in the flock may also be made to change with time, using drive motor controllers that change the voltage of the supplied voltage to the drive motor with time, according to some algorithm embedded in the drive motor controller.The alternative embodiment with split stakes25 It may for practical setup or take-down reasons be inconvenient to have a slider connected to both the motion stake and the decoy. An alternative embodiment of the principles outlined above may then be to use a two-part motion stake, where the motor (with attached wheel and eccentric pin) is fixed on the lower part, and a modified slider is fixed on the upper part, without any direct connection between the decoy body and the slider. This configuration is illustrated in Fig.6. 34932711In this embodiment, the upper part of the motion stake will rotate back and forth, while the lower part remains fixed in, or upon the ground. To have the decoy following the rotational motion of the upper stake, the attachment of the upper rotating part of the motion stake to the balance point on the decoy body must restrict relative rotation between the upper stake and the decoy, 5 while allowing the desired wagging or grazing pendulum motion patterns. A simple, tested solution here has been to use Velcro to connect the top of the upper motion stake to the decoy balance point. Alternative solutions could instead of Velcro use e.g. star screw bits.If the decoy is placed on top of the motion stake with its head and tail in the same direction as the opening in the slider, the generated high-rpm motion pattern will also in this embodiment be side-10 to-side (wagging). If it is mounted with head and tail perpendicular to the opening of the slider, the generated high-rpm motion pattern will also here be front-to-back (grazing). Intermediate placement will likewise give motion pattern variations.Preferred embodiments and technical effectIn a real flock of birds, some will be grazing, some will be walking around looking for food, and a 15 few will be watching (scouting). The wagging scouting behavior emulates birds walking around looking for food. A flock of decoys where there is a mixture of decoys appearing to feed and appearing to walk around will therefore appear natural to live birds and may thus appear more interesting for them as a landing spot.It has also been observed in real hunting situations that placing groups of wagging decoys a few 20 meters behind groups of grazing decoys, «walking» in the directions of the groups of feeders, will incite the live birds to land between the waggers and the feeders, thereby contributing to steering the live birds to land where the hunter wants them to. Making it more predictable where the birds will land, will increase the likelihood for an increased hunting outcome. It may also be expected that this increased predictability in live bird landing behavior decreases the risk of wounding birds, 25 which may happen when shot distances are misjudged, or when the birds land in unexpected places.Alternative embodimentsProgrammable motor controllers combined with more advanced motors, such as stepper motors or servo motors, may be used instead of the proposed modified Scotch yoke mechanism to 30 emulate the basic reciprocating sectorial rotation in the horizontal plane. In a similar manner, may 34932712also for example electronic components be able to shift current supply polarity, thereby reversing the rotation direction of a simple DC motor.Such embodiments will need to include means of speed control (e.g. PWM or switching of power supplies with different voltages) to achieve the described transition from rotation in the horizontal 5 plane at low speeds (scouting) to orthogonal pendulum motions (wagging or grazing) at higher speeds.In the modified Scotch yoke embodiment of the invention, the slider will constitute the decoy motion driver, and in this embodiment the motion driver needs to be connected to the motor, but it cannot be fixed onto it. In embodiments using more advanced motors that are directly able to 10 generate reciprocating motion, the motion driver must be fixed onto the motor shaft, so it can follow its reciprocating motion.The present invention does not restrict itself to depend on any given device for achieving the basic back-and-forth rotation motion pattern (“scouting behavior”). Nor does it restrict itself to rely on any given device for achieving variable speed control. It merely prescribes how a number of life-15 like motion patterns may be generated for decoys balancing on motorized motion stakes, by combining variable motor speed control with a basic horizontal plane reciprocating rotational motion pattern obtained at low motor speed. 34932713Reference numerals100 decoy101 conically shaped cup5 102 stake support point103 decoy underside104 decoy side/decoy wing side105 decoy head/bill106 decoy tail10 200 stake201 upper stake end200a upper stake section200b lower stake section202 yoke connector15 300 drive means301 drive plate/drive wheel302 connector pin310 drive motor320 slider20 321 first slider fixture (stake connection)322 second slider fixture (decoy connection)322’ fore/rear second slider fixture (longitudinal decoy connection) 322’’ lateral second slider fixture (lateral decoy connection)323 slider-drive wheel interconnecting means/slit
