Abstract:
This waterfowl decoy kite is designed in a manner that allows for its deployment over a body of water or other potential waterfowl landing area to facilitate the attracting of specific species to the hunter. The kite is made from a an oval wing and circular stabilizer. The wing and stabilizer may have a variety of notches so as to impart bird like characteristics to the kites flight pattern and visual appeal. The kite may also be painted so as to exhibit a bird like appearance during flight.

Description:
BACKGROUND OF THE INVENTION 
   The present invention relates to an improvement in the methods used to attract waterfowl to a specific hunting site. More specifically, to the use of a spinning kite which has been specially designed in terms of its color schemes and flight characteristics so when it is properly deployed it mimics the desired species of waterfowl&#39;s flight patterns. This waterfowl decoy kite can then be deployed over the desired body of water by the use of a line and fishing pole. 
   Hunters have used decoys in their pursuit of waterfowl throughout history. Generally, this involves the placement of waterfowl decoys either on the surface of body of water or dispersed in an open field. The decoys used for this purpose are constructed in a manner so that they resemble the specific species of waterfowl that the hunter is pursuing thereby increasing the hunter&#39;s chances of attracting that species of waterfowl. 
   The placement of the decoys in this manner constructs an illusion that the area is populated with waterfowl on an identifiable species which in turn draws waterfowl of that species into the area. The hunter takes up a concealed position such as a hunting blind, a camouflaged boat, a stand of reeds or brush, or any other suitable position that is located adjacent to the deployed decoys. This method of hunting allows the hunter to take his quarry as they enter the kill zone to land among the decoys. 
   While this method of hunting waterfowl has proved to be successful over time, it has two related limitations, the decoys are too static and they do not mimic the flight characteristics of waterfowl. While the decoys are at least partially effective in their designed purpose, it has been understood for a long period of time that it would be beneficial to somehow provide a more dynamic lure. As a characteristic of their design, the decoys must be anchored in place thereby reducing their life-like appearance as a real flock of waterfowl is never stationary. Additionally, there has never been a way of accurately mimicking the flight characteristics of waterfowl to further enhance the overall effectiveness of deployed decoys. 
   Some attempts have been made to overcome these limitations of the current state of waterfowl decoys, but they are at best, cumbersome and ineffective. The most notable of these is a light weight replica of a specific water fowl that is designed to fly like a kite. The problems with this approach are many. Firstly, while it cannot be argued that the natural aerodynamic characteristics of birds in general, and waterfowl specifically, is a design that functions properly, this is only the case when the plethora of the involved control surfaces are operated and controlled independently. Attempting to control such a complex aerodynamic form by the use of a static replica and a single string is fool hardy at best. 
   Additionally, the cost of producing such waterfowl decoys is prohibitive. Not only is the intricate form difficult and expensive to produce, the fact that they are intended to exactly replicate individual species means that a hunter must purchase a variety of the decoys if he wishes to hunt more than one species of waterfowl. Finally, the flight characteristics of these decoys are not effective in their designed purposes. This is due to their limitations in design which result in unnatural flight patterns. Not only does this limit their effectiveness, but it also may actually deter the intended quarry from landing in the desired location as, despite their life-like physical appearance, their unnatural flight characteristics may provide clues to incoming waterfowl as to the artificial nature of the intended landing area. 
   Therefore, it can be seen from the forgoing discussion that it would be desirable to provide a controllable flying waterfowl decoy that accurately mimics the flight characteristics of the intended species and which does so in a manner that attracts the attention of that species thereby enticing them to land in the intended kill zone. 
   SUMMARY OF THE INVENTION 
   It is the primary objective of the present invention to provide a waterfowl decoy kite that is designed in a manner that allows it to be deployed over an intended kill zone by the use of a standard fishing pole and line. 
   It is an additional objective of the present invention to provide such a waterfowl decoy kite that is constructed with specially designed control surfaces which provide flight characteristics that mimic those of waterfowl. 
   It is a further objective of the present invention to provide such a waterfowl decoy kite that can be painted in specific patterns enabling it to more accurately replicate specific species of waterfowl. 
   It is a still further objective of the present invention to employ such a waterfowl decoy kite that can be produced in an inexpensive manner and is durable enough to withstand the rigors associated with waterfowl hunting. 
   These objectives are accomplished by the use of a waterfowl decoy kite which is based on the proven technology of rotating or spinning kites. Rotating or spinning kites are well known in the art and generally are made up of a wing element which is horizontally oriented along its longitudinal axis and a centrally located stabilizer element. The stabilizer is oriented vertically in relation to the wing element and bisects its horizontal plane. 
   The present invention is constructed of a light weight but durable plastic such as depron or expanded polypropylene. It has also been found that expanded polyethylene such as that made by ARPAK is ideal. The use of this material not only has benefits in the construction of the present invention as it is easily formed, but al so it is very light yet strong enough to withstand impact and other forces commonly encountered when flying any kite. Additionally, the use of this material provides cost benefits as it is relatively inexpensive allowing hunters to purchase a variety of differing designs of the present invention. This allows them to adjust their hunting techniques to fit varying conditions. 
   The outside ends of the wing element also provide for the rotational attachment of the two lead lines. The two lead lines extend out from this rotational attachment to a point where they join together and to the main line forming a yoke. This method of securing the present invention to the main line in a manner that allows it to spin freely between the rotational attachment of the lead lines. As the wing of the present invention catches the wind, it provides the lift necessary to get it airborne both through its shape and the spinning motion. Additionally, the vertical stabilizer functions much like the tail surface on an airplane to ensure that the invention remains stable in the in the horizontal plane in all wind conditions. 
   The present invention is also equipped with a plurality of features that help it perform the desired operation. The first of these is a plurality of rotational notches formed along the outside edges of the wing. These rotational notches interrupt the flow of air over the wing while the present invention is deployed which in turn alter the spinning characteristics of the wing. Generally, the use of the rotational notches slow the rotation of the wing when in flight. This has been found to enhance its effectiveness in attracting waterfowl into the kill zone. Additionally, during the manufacture of the present invention the size and number of the rotational notches can be varied to suit the specific characteristics of the desired waterfowl species or to adapt to varying weather and environmental conditions. 
   Another of the special features of the present invention are the flutter notches positioned on opposite sides of the stabilizer. The flutter notches operate to disrupt the air flow over the stabilizer in flight. The result of this is to create a side to side wobble in the flight pattern of the present invention. This has been found to enhance the effectiveness of the present invention as it results in a flight characteristic that more closely resembles that of the waterfowl. Additionally, the size and location of the flutter notches can be varied in much the same manner as discussed for the rotational notches to fit any given situation. 
   The present invention is also designed so that its color scheme can be tailored to mimic the plumage of any species of waterfowl. This feature further enhances the effectiveness of the present invention as it increases the odds of attracting the desired species of waterfowl into the kill zone. 
   Finally, an alternative embodiment of the stabilizer component of the present invention has also been contemplated in which its outside edges are constructed with a plurality of small flutter notches forming a serrated edge. This plurality of small flutter notches has been found to impart desirable characteristics to the flutter pattern of the present invention. The serrations on the stabilizer break up the clean edge so as to make the stabilizer appear more bird like, the serrations also aid the stabilizer in resisting side to side movements imparted by side winds, thereby increasing its overall effectiveness in its designed function. 
   For a better understanding of the present invention reference should be made to the drawings and the description in which there are illustrated and described preferred embodiments of the present invention.

   DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Referring now to the drawings, and more specifically to  FIG. 1 , the waterfowl decoy kite  10  is typically deployed over a body of water  26  or other intended kill zone such as field of grain stubble. This deployment can be accomplished in any number of ways but it has been found that the use of a common fishing pole  20  is very effective for this purpose. The fishing pole  20  is anchored to the land  28  by the use of a pole stand  24 . The pole stand  24  holds the fishing pole  20  in an upright manner so that the main line  18  can be positioned in the desired location. The main line  18  is attached at one end to the fishing reel  22  of the fishing pole  20  and to the lead lines  16  at the other. The lead lines  16  are in turn pivotally attached to the present invention. 
   The use of this system allows the present invention&#39;s position to be controlled with respect to the distance between it and the fishing pole  20  by either letting the main line  18  out or retracting it through the operation of the fishing reel  22 . Additionally, the flex that is inherent in fishing poles  20  also enhances the flight characteristics of the present invention as it allows it to oscillate back and forth as the strength of the winds rises and falls. Finally, such use of the present invention allows the hunter  32  to conceal himself from incoming waterfowl  34  in a source of cover  30  that is adjacent to the intended killing zone. 
   The general construction of the present invention is further detailed in  FIGS. 2 ,  3 , and  4 . The present invention is constructed of a light weight but durable plastic such as depron, expanded polypropylene or expanded polyethylene. The use of this material not only has benefits in the construction of the present invention as it is easily formed, but also it is very light yet strong enough to withstand impact and other forces commonly encountered when flying any kite. 
   The present invention is generally made up of a wing  12  which is in turn horizontally oriented with reference to its central longitudinal axis. The wing  12  is the primary lift providing mechanism and also allows for the attachment of the stabilizer  14 . The stabilizer  14  is a vertically oriented component with reference to the wing  12  and functions to provide the present invention with a degree of longitudinal stability during operation. 
   The present invention is secured to the main line  18  through the use of the two lead lines  16 . The lead lines are rotationally attached to the present invention at either outside end of the wing  12  (the exact nature of these attachments will be detailed below). From these points of attachment, the two lead lines  16  converge to form a yoke  17  within which the present invention is mounted and which also allows for its free rotational ability. Also, at the point of convergence, the lead lines are attached to a line swivel  40  or other attachment device providing for their attachment to the main line  18 . This secures the present invention to the fishing pole  20  and allows for its proper deployment and control in the desired area. 
   The wing of the present invention also provides for the placement of a plurality of rotation notches  36 . The rotation notches  36  are illustrated in V-shaped cuts made into the leading edges of the wing  12 . However, the size and shape of the rotation notches are not limited to those depicted in these FIGURES as their size and shape is dependent on the desired flight characteristics. Therefore, the rotation notches as illustrated should not be construed to limit their construction as shown, but are rather for purposes of illustration and simplicity. 
   The function of the rotation notches  36  is to alter the rotational characteristics of the present invention. The addition of the rotation notches alters the airflow over the wing  12  during operation. The primary effect of this is to slow the rotation of the wing  12  when the present invention is deployed for its intended use. The slowing of the rotation has been found to be desirable when these apparatuses are employed in a waterfowl decoy capacity. As stated earlier, the size, shape, and number of the rotation notches can be varied during the construction of the wing  12  to produce the desired characteristics. 
   The stabilizer  14  is also equipped with a feature that affects its flight characteristics, the flutter notches  38 . The flutter notches  38  are larger, in relation to the rotation notches  36 , indentations in the outer edge of the stabilizer  14 . As illustrated, the flutter notches  38  are made up of a pair of concave indentations in the otherwise circular edge of the stabilizer  14 . However, as with the rotation notches  36 , their depicted size, shape, and number should not be construed as being limited to the illustrations, but rather are depicted as such for illustrative purposes only. 
   The placement of the flutter notches  38  in the outer edge of the stabilizer  14  results in the disruption of the airflow over it. This disruption then causes the stabilizer  14  and thus, the present invention itself, to oscillate back and forth along the longitudinal axis of the wing  12 . This oscillation enhances the performance of the present invention as it results in a more life-like appearance thereby attracting more of the intended species of waterfowl  34 . 
   The wing  12  and stabilizer  14  are also colored to mimic the plumage of the desired species of waterfowl  34 . In the illustrated case, the intended species is snow geese which generally have a white body with black wingtips. Accordingly, this example of the present invention is colored so that the stabilizer  14  and central portion of the wing  12  are of a white coloration  46  and the outside tips of the wing  12  are of a black coloration  48 . This color scheme results in a decoy that is especially attractive to snow geese and so is ideal for use when hunting that species. The color scheme used to decorate the present invention can be altered to mimic any species of waterfowl  34  thereby allowing for its effective use in almost any hunting circumstance. 
   The nature of the pivotal attachment of the lead lines  16  to the wing  12  is further illustrated in  FIGS. 5 ,  6 , and  7 . The first component of the attachment system is a central dowel  50  that passes through the longitudinal center of the wing  12 . The central dowel  50  serves two functions. The first of these to provide a greater degree of structural rigidity to the wing  12 . The added structural rigidity helps the wing  12  withstand the forces placed on it during the operation of the present invention. The central dowel  50  is generally made of wood but it can be formed from any other suitable material such as metal or plastic so long as it provides the desired rigidity to the present invention. 
   The second function of the central dowel  50  is to provide a place to secure the other attachment components. In this, the outer ends of the central dowel  50  extend beyond the outside edges of the wing  12 . This then allows for the insertion of the attachment pins  44  and the attachment bracket  42 . The attachment bracket is a small rectangular piece of a lightweight metal or other similar material that has a hole at either end. The first of these is the attachment pin hole  41  that facilitates the pivotal attachment of the attachment bracket  42  to the central dowel  50 . The attachment pin  44  is a nail-like apparatus having an elongated pin shaft  45  and a flattened attachment pin head  43 . Additionally, the outside diameter of the pin shaft  45  is smaller than the inside diameter of the attachment pin hole  41  through which it passes. 
   The attachment is accomplished by passing the pin shaft  45  of the attachment pin  44  through the attachment pin hole  41  and driving it into the central dowel  50 . This allows the attachment bracket  42  to freely rotate around the attachment pin  44  while being retained by the flattened attachment pin head  43  which ensures that the attachment bracket  42  cannot slip off the end of the attachment pin  44 . 
   The other end of the attachment bracket  42  contains the line attachment hole  52 . The line attachment hole  52  allows for the fixing of the lead lines  16  to the attachment bracket  42 . This attachment can be accomplished in any number of ways including a simple knot. The use of the attachment bracket  42  and its rotational attachment to the central dowel  50  allows the present invention to freely spin within the yoke  17  created by the configuration of the lead lines  16 . The spinning motion and the operations of the rotation and flutter notches,  36  and  38 , of the present invention not only allow it to fly, but also create the waterfowl  34  attracting qualities that are central to its designed operation. 
   Finally, an alternative embodiment of the stabilizer  14  component of the present invention has also been contemplated and is illustrated in  FIG. 8 . This embodiment of the stabilizer  14  is referred to as the serrated stabilizer  54  and differs in the fact that it is constructed with a plurality of small flutter notches  58  forming a serrated edge  56 . This incorporation of this plurality of small flutter notches  58  has been found to impart desirable characteristics to the flutter pattern of the present invention by making the invention appear more bird like in its movements and aiding the stabilizer  14  in resist side to side movement imparted by side winds, thereby increasing its overall effectiveness in its designed function. 
   Although the present invention has been described in considerable detail with reference to certain preferred versions thereof, other versions are possible. Therefore, the spirit and scope of the appended claims should not be limited to the description of the preferred versions contained herein.
