Spinning wing decoy technology

A system, apparatus and method for controlling the stoppage of a spinning wing of a migratory bird decoy. When power is turned off by a remote controller a motor shaft needs to stop spinning so that the dark side of a wing stops facing upward. At least one magnet is attached to the motor shaft and a ferromagnetic magnet target is disposed off of the motor shaft, which causes the motor shaft/wing to be oriented in the correct position with the Dark Side (Feather) Up when power is terminated to the spinning wings.

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates, generally, to hunting decoy systems, apparatus and methods. Particularly, the invention relates to a spinning wing migratory bird (waterfowl, ducks, geese, doves, and the like) decoy. Most particularly, the invention relates to a system, apparatus, and method for controlling the stoppage of spinning wings on a decoy to maximize the attraction of migratory birds to the decoy.
2. Background Information
Decoys have been used for many years to imitate an animal, such as a bird, for the purpose of attracting other birds to a particular location for hunting or other purposes. Modern migratory bird and waterfowl decoys come in many types, including floating, ground placed, and stake or base mounted. Decoy bodies may have fixed wings or movable wings. Movable wings may be spinning, flapping, or the like. And movable wings may be actuated by motor power, by wind, or by other forces. Many waterfowl decoys are constructed of inexpensive plastic materials.
The present invention provides an improved spinning wing migratory bird decoy and a wing control system. When the wings rotate on a spinning migratory bird wing decoy (also known as “spinners), a visible “flash” is given off because one side of the wing is dark (feather print) and one side of the wing is light, preferably white. Commonly, hunters use a remote control to turn off the spinners because geese and sometimes ducks will not land when the wings are spinning. A major problem that occurs is that sometimes the white side of the wing stops facing up. The white side facing up doesn't look natural, and this tends to scare birds away. Where the wing stops in the prior art is completely random.
Attempts have been made to try to add a weight to one side of the wings to stop them in a certain way, but they have failed. Weighting creates significant vibration, wobble, and noise. Further, weighting ruins the bearings of the motor quickly. Insofar as is known, no one has come up with a way to control how the wing stops on a spinner.
Applicant has also developed a decoy, system, and method for controlling the stoppage of a spinning wing via its motor. When power is turned off by a remote controller, a photo eye sensor system identifies when a motor shaft needs to stop spinning so that the dark side of a wing stops facing upward. When the motor shaft is in a correct location, a wing shaft control cylinder is engaged, which locks the motor shaft/wing in the correct position with the dark side (Feather) Up. When engaged, a pin from the cylinder goes into a motor gear housing, which stops and holds the wing shaft, and therefore the wing, in the correct position.
Existing technology in this field is believed to have significant limitations and shortcomings. For this and other reasons, a need exists for the present invention.
All US patents and patent applications, and all other published documents mentioned anywhere in this application are incorporated by reference in their entirety.

DETAILED DESCRIPTION
The description that follows describes, illustrates and exemplifies one or more embodiments of a spinning wing decoy with correct, Feather Up positioning. This description is not provided to limit the disclosure to the embodiments described herein, but rather to explain and teach various principles to enable one of ordinary skill in the art to understand these principles and, with that understanding, be able to apply them to practice not only the embodiments described herein, but also other embodiments that may come to mind in accordance with these principles. The scope of the instant disclosure is intended to cover all such embodiments that may fall within the scope of the appended claims, either literally or under the doctrine of equivalents.
It should be noted that in the description and drawings, like or substantially similar elements may be labeled with the same reference numerals. However, sometimes these elements may be labeled with differing numbers in cases where such labeling facilitates a more clear description. Additionally, the drawings set forth herein are not necessarily drawn to scale, and in some instances proportions may have been exaggerated to more clearly depict certain features.
Referring initially to FIGS. 1 to 3, the present invention provides an improved spinning wing migratory bird decoy 10 and a wing control system thereof. When the wings 14 rotate on a spinning migratory bird wing decoy (also known as “spinners), a visible “flash” is given off because one side 18 of the wing is dark (for example a feather print) (See also FIGS. 4 and 6) and one side 20 of the wings 14 is light, preferably white (See also FIGS. 5 and 7). The flash results from the contrast of colors or tones, between dark and light surfaces. Commonly, hunters use a remote control (not shown) to turn off the spinners because geese and sometimes ducks will not land when the wings are spinning. A major problem that occurs is that sometimes the white side 20 of the wing stops facing upward, as shown in FIGS. 3 and 5. The white side 20 facing up doesn't look natural, and this tends to scare birds away. Where the wings stop in the prior art is completely random.
The wing stopping system and method, and the motor module of the present invention may optimally be implemented in a spinning wing migratory bird decoy such as shown and described in U.S. Pat. No. 10,638,747 and/or the LUCKY HD or Hdi Decoys manufactured and sold by Applicants' assignee, Lucky Duck Decoys of Baldwin, Wisconsin USA, all of which are hereby incorporated by reference herein.
FIG. 1 is a perspective view, from the top front, of an embodiment of a spinning wing migratory bird decoy 10. The decoy 10 has a body 12 from which wings 14 A and B extend. The wings 14 are coupled to the body 12 preferably by connectors 22. In one embodiment, the decoy 10 is mountable on a stand 16. However, the decoy 10 may be a floating style decoy or otherwise placed directly on a surface. One side 18 of the wings 14 have a dark surface look or color, typically including a feather pattern that mimics the top or outer side of waterfowl or other migratory bird wings. The opposite side 20 of the wings 14 have a light look or color, typically white and devoid of a feather pattern. The difference in look mimics a live bird.
FIG. 1 is a perspective view, from the top front, of a spinning wing migratory bird decoy 10 with a body 12 and a pair of wings 14A and 14B extending laterally from the body 12. The decoy 10 is mounted on a stand 16, but it may be positioned otherwise. The wings 14 have a generally flat panel structure with one side 18 having a dark surface look or color, typically including a feather pattern that mimics the top or outer side of waterfowl or other migratory bird wings. FIG. 2 is a perspective view, from the bottom front, of the decoy and showing the opposite side 20 of the wings 14 with a light look or color, typically white and devoid of a feather pattern. When the wings 14 are powered and spin, the alternation between dark 18 and light 20 sides creates a flickering or flashing image that is attractive to other birds because it simulates a bird flapping its wings, and particularly when viewed from above, a bird in the process of landing on water. FIG. 3 is a substantially identical view of the decoy 10 as in FIG. 1, wherein the wings 14 are rotated so that the light side 20 of the wings 14 are oriented upwardly. FIG. 4 is a top view of the decoy 10 wherein the wings 14 are stopped with the dark, feather side 18 of the wings 14 oriented upwardly. FIG. 5 is a top view of the decoy 10 wherein the wings 14 are stopped with the light, featherless side 20 of the wings oriented upwardly. FIGS. 1 and 4 show the desirable position to attract waterfowl, and FIGS. 3 and 5 show the position that is not desirable.
FIG. 6 is a detailed top view of the dark, feather side 18 of a wing 14. FIG. 7 is a detailed top view of the light, featherless side 20 of the wing 14. The wing 14 panels have a shaft 21 that extends longitudinally away from a proximal end of the panel. The shafts 21 each have a male-type connector 22 which mates with a complementary female-type connector or connection end 24 of a motor shaft. In FIG. 8, the female-type connector 24 has an alignment notch 26, and the male connector 22 has a complementary post or pin that fits in the notch 26. In a preferred embodiment, the alignment notch 26 is aligned upwardly with the dark face 18 of the wings 14 to ensure that the dark sides of the wings 14 are facing upwards when spinning power ceases. The motor module 30, not shown in these Figures, is disposed inside the decoy 10 body 12.
FIGS. 8 to 13 show an embodiment of a motor module 30 for controlling the feather side up stoppage of spinning wings 14, of the decoy 10 of the present invention. The motor module 30 has a housing 32, preferably having two parts, left and right, 32A and 32B, that contain an internal motor 33. The motor 33 is preferably a direct drive DC motor. Mounting flanges 34 A and B connect the motor housing 32 to the interior of the body 12. The connection ends 24 are rotatably driven by the motor 33. The connection ends 24 extend through the flanges 34 and then through lateral apertures 36 in the body 12 to the exterior, whereby they are connectible and dis-connectible to the wings 14 via connectors 22. When the motor 33 is powered ON, the connection ends 24 rotate, which spins the connected wings 14. However, in this configuration, when the motor 33 is powered OFF, the connection ends 24 continue to spin for a certain period of time until friction on wings 14 stops them in a random position, including the undesirable Feather Down position discussed earlier. Significantly, the motor module 30 has at least one magnet 40 disposed in a predetermined position on the connection ends 24 and a complementary ferromagnetic metal bar magnet 42 disposed on the housing 32 such that it is disposed in line with the vertical axis “A” of the motor module 30 and decoy 10 as a whole; the vertical axis “A” can denote the position of decoy 10 in use as illustrated in FIG. 1. In a preferred embodiment, each connection end 24 has two (2) magnets 40 A and B. The magnets 40A/B are disposed on opposite sides of the connection ends 24 and have opposing polarities. One of the magnets 40A is attracted to the bar magnet 42 while the other magnet 40B pushes away from the bar magnet 42. The opposing polarities of the magnets 40A/B can generate magnetic forces to further ensure that the magnets 40A/B are perpendicularly aligned with the alignment notches 26, so that the wings 14 are stopped in the correct, dark side UP, position. As the connection ends 24 spin progressively slower during Power OFF, the magnets 40 A/B begin to exert their opposing forces on the poles of the bar magnet 42 until finally the magnets 40 A/B and bar magnet 42 align with one another in a stable position. This position is aligned with the desirable Feather UP view, the wing panels 14 A and 14B being generally perpendicular to the vertical axis A and generally parallel to the ground or water location of the decoy 10.
The decoy has power and control circuitry including a micro controller and a receiver for communicating with a remote controller and for controlling the motor. In a further preferred embodiment, the micro controller provides a fast, short burst of power to the motor 33 upon deactivation of power to the wings. This burst of power causes a twitch to the wings, which was found to even further improve wing stoppage in the desired position.
Although the apparatus and methods have been described in connection with the field of hunting, it can readily be appreciated that it is not limited solely to such field, and can be used in other fields.
