Abstract:
A remote controlled animated bird decoy including a body and an oscillating mechanism to simulate horizontal life-like movements. An oscillating mechanism oscillates the bird decoy body and includes a battery-operated motor which is remote controlled. A sensory device with memory programmed to provide oscillatory motion is connected to the motor which provides, in turn, horizontal oscillatory motion of the bird decoy body so that the bird decoy body oscillates in a horizontal plane in relation to the ground surface simulating a turning movement of a live bird. A full body, shell or silhouette bird decoys of prior art can be adapted or modified to include the oscillating mechanism and turn or oscillate like a live bird.

BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to devices for attracting game animals, and more particularly to animated decoy devices especially adapted for attracting waterfowl. 
     2. Description of the Prior Art 
     Decoys presently available typically include silhouette decoys, windsock decoys, shell decoys, and full body decoys. Windsock decoys are popular where movement is desirable to give the appearance of movement like a live bird. When prevailing wind conditions are favorable the windsock decoys are inflated by the wind simulating the appearance of a full body bird. Too much wind will damage the windsock fabric or the fabric attachment to its head. The effectiveness of windsock decoys are dependent on unpredictable wind. 
     Most decoys, with the exception of windsock decoys, are stationary objects which give a visual appearance of a bird. However, such stationary decoys are not realistic because real animals move. In this respect, it would be desirable for an animal decoy to move in a lifelike manner, rather than be stationary. 
     Of special interest are decoys which simulate waterfowl, such as ducks and geese, for hunting and to attract live birds or for other uses, including aesthetic purposes such as display, gardens, and lawns. In the prior art, waterfowl decoys are known which have wings or heads that are mechanically moved by pulling a string. For a more realistic decoy, it would be desirable if a waterfowl decoy body oscillated horizontally imitating a live bird. That is, a decoy, which turned from one position to another or oscillated from one position to another or any variation thereof would be more lifelike. Rather than a decoy being animated by unpredictable wind or controlled or animated by strings or chords which tangle in or snag on shrubs, bushes, or other objects, it would be desirable for an animated animal decoy to be powered by a motor and remotely controlled by a human operator. 
     Throughout the years, a number of innovations have been developed relating to waterfowl decoys. The following U.S. patents are representative of some of those innovations: U.S. Pat Nos. 4,172,335; 4,611,421; 4,753,028; 4,885,861; 4,928,418; and 5,172,506. More specifically, U.S. Pat No. 4,172,335 discloses a goose decoy that has no wings and is immobile when used. Leg assemblies have been employed to support decoys upright. U.S. Pat. No. 4,658,530, by Ladehoff, U.S. Pat. No. 4,885,861, by Gazalski, and U.S. Pat. No. 5,205,060, by Franceschini, disclose various types of leg assemblies which support a decoy in an upright, stationary position. These leg assemblies are hereinafter referred to as a “plug-in leg assembly. 
     U.S. Pat. No. 2,441,753 to Carpenter on May 18, 1948 shows a single panel type decoy mounted like a weather vane on a vertical shank of a stake for turning in the wind. The pivot shank theory is also shown in U.S. Pat. No. 2,711,608 which issued to Fulster Jun. 28, 1955. In Aug. 6, 1991 U.S. Pat. No. 5,036,614 issued to Jackson which included a pivoting mechanism to pivot or oscillate the decoy body in a vertical plane to imitate a feeding action with the supporting assembly which pivots manually to present a high profile to game birds of the feeding action. U.S. Pat. No. 5,168,649, by Wright, discloses the posture of a hen turkey decoy, whereby the turkey decoy drops vertically downward in a nonpivotal fashion. U.S. Pat. No. 5,036,614, by Jackson, discloses a decoy which pivots in a vertical plane. U.S. Pat. No. 5,233,780, by Overholt, discloses a remotely controlled turkey decoy which produces sound and movement in one circular direction. U.S. Pat. No. 3,689,927, by Boston, disclosed a motorized, propeller driven decoy for movement in the water. U.S. Pat. Nos. 2,576,207 and 2,575,252, by Berger, disclose a bird decoy with flapping wings and turning head.

     DETAILED DESCRIPTION OF THE INVENTION 
     In the following description it is to be understood that such terms as or references to duck decoy or goose decoy are words of convenience and are not to be construed as limiting terms. Referring to a bird decoy and particularly FIG. 1 is a full body goose decoy indicated by the numeral  10  attached to an adapted plug-in leg apparatus  26  mounted on a housing and support device  36  illustrating an embodiment of the invention. The bird decoy  10  in FIG. 1 is an upright or standing position having a head  9  and a neck  8 . In FIG. 1, the bird decoy  10  oscillates horizontally under the influence of an oscillatory mechanism  37  mounted inside a housing and support device  36 . The present bird decoy is more useful in imitating a bird on the ground by mimicking bird feeding or sentry motion with oscillating turns 30° to 180°. 
     The embodiment of the invention includes a manual switch  12 , or a switch with a receiver  13  activated by radio waves or the like connected operatively to a power supply  14  comprised of either dry or wet cell batteries which, in turn, is connected operatively to a sensor device with memory  15  comprising an automatic electronic reverse polarity switch having selective settings which reverses the rotation of and which is operatively connected to an electric gearhead motor  16  or to a servo having reversible rotation, having not less than 3.0 voltage, not less than 0.2 rpm but having stall torque more than 2.4, such as hat made by Hankscraft Motors or found in the Tower Hobbies catalog or Edmund Scientific Catalog. The electric motor  16  has a rotating shaft.  18  The power supply  14  is not less than two size D batteries. The switch with a receiver  13  is powered by an auxiliary power supply.  41  In FIGS. 10 and 11 the schematic electronic and electrical setup for the invention are illustrated. 
     FIG. 2 illustrates an embodiment of the invention with the power supply  41 , sensor device with memory  15 , switch with receiver  13 , and power supply  14 , and motor  16  are mounted fixedly inside a housing  36  on supporting members  17 , collectively comprising the oscillatory mechanism  37 . The sensor device with memory  15  activates and controls the degree and direction of oscillation of the motor  16 , thereby controlling the rate and degree of the oscillation of rotating shaft  18 , which in turn selectively oscillates or rotates the decoy body horizontally. A sensor device with memory  15  controls the rate and degree of oscillation of the rotating shaft  18 . In FIG. 11 there is illustrated the remote control device  48 . 
     FIG. 3 illustrates a further embodiment of the invention with a manual switch.  12   
     In FIGS  2 ,  3  and  5 , the rotating shaft  18  extends through a bushing  52  mounted in the top end member  47  of a housing and support device  36 , a antifriction device  11  mounted operatively on the housing  36 . In FIG. 5, the rotating shaft  18  extends vertically through an opening  38  in the top of the antifriction device  11 . In FIG. 4 the geometrically shaped member  19  at the terminal end of the rotating shaft  18  fits slidably into a matching slot  20  in the mounting plate  45  mounted on the top of the antifriction device  11 . The mounting plate  45  then is attached to the plug-in apparatus  26  (FIGS. 1,  2 ,  3 ). The plug-in apparatus  26  then as shown in FIGS. 1,  2 ,  3 , plugs into a full body decoy. 
     In an embodiment of the invention as shown in FIGS. 2 and 3, the antifriction device  11  operatively mounts on a plurality of ball bearings  46  in the top end member  47  of the housing and support device  36 . The antifriction device  11  facilitates oscillation of the decoy. 
     By way of further explanation, the top of the antifriction device  11  is attached to a mounting plate  45  which is, in turn, attached to the bottom of the plug-in apparatus  25 . It will be understood in the art that the plug-in apparatus varies  26  in size, shape, and features in order to plug-in to different sizes and models of full body decoys with plug-in foot assemblies. 
     It will be understood by those in the art that the axis of the horizontal oscillation of the decoy body is the same as the axis of the oscillation of the rotating shaft  18 . 
     In FIGS. 2,  3  and  5  the base end apparatus  32  slides over the bottom end of the housing and support device  36 . The base end apparatus  32  is attached to the housing and support device by a fastener  48  including a bolt or screw, and is connected to a structural member  51  reinforcing the inside of the housing and support device  36 . In a further embodiment of the invention, the base end apparatus includes a base lid  49  which screws into the bottom of the base end apparatus  32 . In an embodiment of the invention, the base end lid  49  also includes a knob  50  to facilitate turning the base end lid. 
     In an embodiment of the invention, a base plate  28 , larger than the housing and support device  36  is adjustably secured to the base end apparatus  32  by means of a threaded main spike  31  and a series of threaded nuts  34 . In FIG. 3, the base plate  28  is perforated with a multiplicity of holes  29  for the insertion of spikes or stakes  30  to be inserted by manual pushing or hammering into the ground. The base plate  28  has a threaded main spike  31  extending vertically downward approximately through the center of the base lid  49  to the ground and extending vertically upward through an opening approximately in the center of the top of the housing and support device  36 . The main spike  31  is adjustably secured by threaded nuts  34  at its intersection or bottom of base lid  49 , the structural base member  51 , and the base plate  28 . The base end apparatus  32  and the structural base member are attached to the housing and support device by a fastener  48 . The upper portion of the main spike is threaded  33  permitting the base plate  28  to be selectively moved and adjusted upward or downward and fixed in place by threaded nuts  34 , thereby raising or lowering the decoy body. 
     A method of incorporating the oscillatory mechanism  37  in a plug-in assembly such as illustrated, by way of example, in (FIG. 6) creates a portable mechanism that provides animation to a bird decoy. For the sake of explanation, it may be pointed out in FIG. 6 that a plug-in leg assembly  22  of a full body decoy of prior art is modified by eliminating the legs and feet  24  portion resulting in a plug-in apparatus  26  having the plug-in features and having an opposing flat bottom surface  25 . It will be understood by those skilled in the art that there is a sufficient amount of the plug-in features  26  adapted for plugging-in to the full body decoy remains. The modified plug-in apparatus  26  is fixedly attached as illustrated in FIGS. 1,  2  and  3  to a mounting plate  45  mounted on the antifriction device  11 . The antifriction device  11  as shown in FIG. 5 mounts over the top of the housing  36  and support device  36  and the interior of the antifriction device rotates on ball bearings  46  set in the top of the housing and support device  36 . 
     The rotating shaft  18  extends vertically through an opening  40  approximately in the center of the top end member  47  of the housing and support device  36  and an opening  52  in the center of the antifriction device  11 . A geometrically-shaped member  19  attached at the terminus of the rotating shaft  18  inserts through the top of the antifriction device  11  into a slot  20  in the bottom of the mounting plate  45  which is attached to the bottom of the plug-in apparatus  26 . The bearing device  11  is then mounted on a housing and support device  36 , thereby transferring the oscillatory motion from the motor  16  to the plug-in apparatus  26 . (FIG. 7) The end result is a modification of a stationary full body decoy  10  of prior art having plug-in leg assembly features to a decoy with oscillatory motion mimicking a bird in sentry or feeding positions. The plug-in apparatus  26  is of selective size and configuration depending on the particular conventional decoy model, and the oscillatory mechanism  37  as shown in FIG. 2 and 3, is thereby adapted to a variety of prior art conventional full body bird decoys with feet that detach. For the sake of explanation, it may be pointed out that said modified plug-in apparatus  26  fits the corresponding full body decoy. 
     In another method of incorporating the invention to a shell decoy  23 , a mounting plate  45  secured to a antifriction device  11  and a housing and support device is attached inside a hollow or shell decoy in FIG. 8 not having plug in feet  27  at the approximate point of equilibrium. (FIG. 8) The base end apparatus  32  and mainspike  31  secured in the earth support the shell decoy  23  in a standing position. The oscillatory mechanism  37  described in FIG. 2 and 3 is employed in this embodiment. (FIG. 8) 
     In another method of incorporating the oscillatory mechanism  37  contained in a housing and support device  36  described in FIGS. 2 and 3 are attached, as illustrated in FIG. 9, to a silhouette decoy  42 , thereby creating an animated decoy. In an embodiment of the invention includes an L-shaped device  43  which is securely attached to the mounting plate  45  (FIGS.  2 , 3 , 5  and  9 ) which is attached to a antifriction device  11  and in turn to a housing and support device  36 . The L-shaped device  43  is then attached fixedly to the bottom of the silhouette d(coy at the point of equilibrium in (FIG.  9 ). The oscillatory mechanism  37  described in FIG. 2 and 3 are employed in this embodiment. The base end apparatus  32  and main spike  31  support the decoy in a standing position.
