Flying bird replica

## Abstract

A flying bird replica comprising a body and a pair of wing members. The body is elongated having a configuration resembling that of a bird body. The body has a top surface, two sides, and a transverse slot extending between the sides. The wing members are interconnected by a flexible cord disposed in the slot below the top surface of the body. The cord is tensioned for urging the wing members together such that the wing members are held in a fixed position relative to the body. A horizontal support rod holds the body and wing members in a realistic orientation and permits tilting of the body and wings about the support rod to resemble a bird in flight.

## Background
This application claims the benefit of U.S. Provisional Application No. 61/035,687, filed Mar. 11, 2008.


FIELD OF THE INVENTION
This invention is directed to a replica of a flying bird, and particularly to a replica that is light weight, sturdy, easily assembled and disassembled, and capable of motion realistically depicting a bird in flight.
BACKGROUND
The use of bird replicas as hunting decoys is well known. A substantial amount of ingenuity has been applied to creating bird decoys that realistically depict waterfowl and other birds of interest to hunters and bird watchers. Particular attention has been paid in the most recent generation of decoys to creating bird replicas that realistically represent a bird in active flight in order to maximize the appearance of safety to overflying wildfowl.
In addition to the established use of bird replicas as decoys, replicas of raptors are commonly used as deterrents to discourage the presence of unwanted birds such as pigeons and seagulls in a variety of settings such as buildings and vessels, and also in agricultural environments where they are used to ward off rodents and other pests.
One problem with the existing art is that wildfowl eventually become inured to bird replicas whether the replicas are acting as an attractive decoy or as a deterrent. Another problem is that many replicas, particularly decoys, are bulky, awkward to handle, heavy, and expensive to manufacture. Moreover, some require complicated assembly and disassembly procedures which must frequently be performed under adverse environmental conditions in the field.
Any bird replica which can realistically depict the natural movements of a bird in flight and avoid the above disadvantages will serve many useful needs.

DESCRIPTION OF THE ILLUSTRATED EMBODIMENT
A flying bird replica, indicated generally at 10 in FIG. 1A, comprises a body 12, a pair of wing members 14, and a support apparatus 16. With additional reference to FIG. 2, the body 12 is elongated in form, having head and tail ends 18, 20, and left 22, right 24, upper 26, and lower 28 sides. The left and right sides 22, 24 of the body 12 each have a wing opening 30 in the form of a longitudinally extending recess having horizontally disposed top and bottom receiving walls 31 extending inwardly from said sides. A transverse slot 32 extends between the left and right sides 22, 24 of the body 12 and intersects with each recess 30. As seen in FIGS. 2E-2G, slot 32 is defined by two opposing side walls 34 that extend downward from the top surface 36 of the upper side 26 of the body 12, and a floor 40. It is contemplated that both the depth of the slot 32 and the shape or profile of the floor 40 may vary. As shown in FIGS. 2A-2B, the floor 40 of the slot 32 has two outer ends 38 adjacent the sides 22, 24 of the body 12, and a middle section 42 disposed between the two outer ends 38. The middle section 42 is higher than the outer ends 38 and may optionally have a convex profile.
A hollow channel 44 extends through the body 12 longitudinally from a forward opening 46 below the head end 18, shown in FIG. 1B, to a rear opening 48 in the top surface 36, near the tail end 20 of the body 12, shown in FIG. 1A. Referring back to FIG. 2E, the channel 44 is substantially coincident with a plane bisecting the body 12 into lateral halves. In the illustrated embodiment, the channel 44 is disposed at an angle of about nine degrees relative to a longitudinal axis A extending between the head 18 and tail 20 ends of the body 12 to realistically simulate the body tilt of a bird in flight. In alternate embodiments, channel 44 may be disposed at an angle of between zero and thirty-five degrees relative to axis A, but preferably at an angle between approximately five and fifteen degrees. The hollow channel 44 is disposed somewhat higher than the longitudinal center of gravity such that the portion of the body 12 below the channel 44 is heavier than the portion of the body 12 above the channel 44.
A wear-resistant tube 50 having a front 52 and rear 54 end lines a substantial length of the channel 44. The rear end 54 of the tube 50 is disposed in the channel 44 below the top surface 36 of the body 12.
As shown in FIG. 2, the shape of the wing members 14 connotes the extended wing members of a bird in flight. Each wing member 14 comprises a proximate portion 56 near the body 12, a narrower distal portion 58 extending outward and rearward from the proximate portion 56, and horizontally disposed top and bottom surfaces 62, 64. An aperture 60 extends from the top surface 62 to the bottom surface 64 of the proximate portion 56 of the wing member 14. See also FIG. 2C. The forward edges 66, 68 of the proximate and distal portions 56, 58, are smooth and rounded giving the wing members 14 a realistic configuration and good aerodynamic properties. The back edge 70 of the proximate portion 56 of the wing member 14 is also smooth and rounded. The back edge 72 of the distal portion 58 is ridged or crenulated to represent the feathers of a bird. With additional reference to FIG. 2D, an insert 74 extending inwardly from the inner face 76 of the proximate portion 56 of each wing member 14 has horizontally disposed upper and lower insert walls 57 that are shaped and sized to closely conform to the receiving walls 31 of the wing opening 30 such that the insert 74 fits snugly and removably into the wing opening 30 on the body 12. The inner face 76 abuts the side of the body 12 surrounding the wing opening 30 so as to limit the depth the insert 74 is embedded in the wing opening 30. Aperture 60 is spaced distally from the inner face 76 of the proximate portion of the wing member 14. A small conduit 78 extends from the vertically disposed outwardly facing inner wall 80 of the aperture 60 to the interior edge 82 of the insert 74 for accommodating flexible cord 84 which interconnects the wing members 14, as shown in FIG. 2C. Each end of the cord 84 is secured in each aperture 60 by placing a washer 86 on each end of the cord 84 and forming a knot 88 at the end of the cord 84 so that the washer 86 is disposed between the knot 88 and the inner wall 82 of the aperture 60. The insert 74 is thicker in its middle region, as shown in FIGS. 2 and 2D, to counteract any loss of strength due to conduit 78.
The body 12 and wing members 14 are constructed of a flexible and light-weight material that allows the replica 10 to move in a manner similar to a bird in flight upon exposure to air flow or wind currents. In one embodiment, the body 12 and wing members 14 are constructed from Expanded Polypropylene Particle (EPP) foam, but other materials that allow the replica to perform in a reasonably life-like manner may also be used.
In the embodiments illustrated in FIGS. 2E-2F, support apparatus 16 comprises a relatively rigid rod 90 having a vertical portion 92 and a horizontal portion 94. The horizontal portion of rod 94 extends through the channel 44 in the body 12, holding the channel 44 in a substantially horizontal position and providing a horizontal axis about which the body 12 and wing members 14 may freely rotate, as depicted in FIG. 3B. The vertical portion 92 of rod 90 is freely received in the vertical top bore 96 of the top portion of post 98 or other support member anchored in the ground, providing thereby a vertical rotational axis for the side-to-side pivoting motion shown in FIG. 3A responsive to wind currents indicated by the arrows.
Referring to the embodiment in FIG. 2E, the horizontal portion 94 of the rod 90 has two annular grooves 102f, 102r, as shown in FIG. 2. The front and rear grooves 102f, 102r. are spaced apart by a distance slightly greater than the length of the tube 50. With the horizontal portion 94 of the rod 90 inserted through the tube 50 in the channel 44, two washers 118 are positioned on the rod 90 such that each washer 118 is between one of the tube ends and one of the grooves 102. An e-clip 104 inserted into each groove 102f, 102r. minimizes longitudinal movement of the horizontal portion 94 of the rod 90 in the tube 50.
The embodiment illustrated in FIG. 2F does not have a tube 50 that lines channel 44. Instead, in this embodiment, the support apparatus 16 comprises forward and rear sleeves 106, 108 press-fit inside channel 44 from the forward and rear openings 46, 48, respectively. Forward and rear sleeves 106, 108 each have an inner diameter slightly larger than rod 90 such that forward sleeve 106 closely surrounds rod 90 adjacent forward opening 46, and rear sleeve 108 closely encircles rod 90 adjacent rear opening 48. Rod 90 is thus confined against excess lateral movement yet pivots freely in sleeves 106, 108. Forward retaining collar 110 is removably press fitted over rod 90 immediately in front of forward sleeve 106 and rear retaining collar 112 is removably press fitted over rod 90 immediately behind rear sleeve 108, thereby confining rod 90 against longitudinal movement with respect to sleeves 106, 108 and, hence, body 12. It will be understood that a single support assembly 16 can support more than one bird replica 10.
In an alternate embodiment of a flying bird replica 10 illustrated in FIGS. 5-6, the support apparatus 16 for one or more replicas 10 is provided by a cord or string 114 suspended between two supports 116 anchored to a ground surface. The string 114 passes through the channel 44 of each replica 10 and is secured in place relative to the body 12 of each replica 10 using the sleeve and retaining collar arrangement described above or by any other practical means.
Assembly of the bird replica 10 in the field is remarkably quick and easy. When the cord is in a stretched state, the maximum spacing between the inner faces 76 of the proximate portions 56 of the wing members 14 is less than the distance between the sides 22, 24 of the body 12. Further separation of the wing members 14, as shown in FIG. 2A, therefore stretches and puts the cord 84 under tension. With the wing members 14 held apart an adequate distance, the inserts 74 are then inserted in the wing openings 30 on the sides 22, 24 of the body 12 as shown in FIG. 2B, while the flexible cord 84 between the wing members 14 is guided into the slot 32 in the upper side 26 of the body 12, shown in FIGS. 2G-2H. With the inserts 74 fully seated in wing openings 30, the stretched cord 84 pulls the wing members 14 together thereby retaining the inserts 74 in the wing openings 30 and holding the wing members 14 in a fixed position relative to the body 12. See FIGS. 2A, 2B. As perhaps best seen in FIG. 2, the wing openings 30 are angled with respect to the longitudinal axis of the bird body 12. Therefore, when the wing members 14 are attached to the body 12, the forward edge 66 of the wing members 14 is higher than the back edge 72 giving a realistic appearance to the assembled replica 10.
To secure the body 12 to the support rod 90 in the embodiment illustrated in FIG. 2E, the horizontal portion 94 of the rod 90 is inserted through the channel 44 such that groove 102r. extends from rear opening 48. Washers 118 are positioned on each end of the rod 90 such that one washer 118 is between an annular groove 102r. and the rear end 54 of the tube 50 and the other washer 118 is between forward opening 46 and the corner between the vertical and horizontal sections 92, 94 of the rod 90. An e-clip 104 is inserted into groove 102r.. Then the rod 90 is pulled forward such that the horizontal portion 94 is drawn through channel 44 toward the head end 18 of the body 12 until the washer abuts the rear end 54 of the tube 50 inside channel 44. The other washer 118 is then moved between the front end 52 of tube 50 and groove 102f, and the remaining e-clip 104 is inserted into groove 102f.. The washer 118 and e-clip 104 combination adjacent each end of tube 50 restricts longitudinal movement of the body 12 along rod 90. The vertical portion 92 of rod 90 is then inserted into vertical bore 96 of post 98 to establish the vertical rotational axis.
In the embodiment illustrated in FIG. 2F, forward and rear sleeves 108, 110 are press-fit into channel 44 from the forward and rear openings 46, 48 of the channel 44, respectively. The forward retaining collar 110 is slid onto the horizontal portion 94 of the rod 90 towards vertical section 92. Then horizontal portion 94 of the rod 90 is inserted through channel 44 such that it passes through sleeves 108, 110 and extends from rear opening 48. The rear retaining collar 112 is positioned on horizontal portion 94 and both the front and rear retaining collars 110, 112 are slid along horizontal portion 94 to the positions shown in FIG. 2F to restrict longitudinal movement of the body 12 along rod 90. The vertical section 92 of rod 90 is then inserted into the bore 96 of support post 98.
One great advantage of the invention is that the entire assembly process for the described embodiments can take less than one minute.
When exposed to wind or air currents as indicated by the arrows in FIG. 3A, the bird replica 10 swings to face into the direction of the air flow, thereby indicating the direction of the wind like a weathervane. Moreover, the body 12 rocks reciprocally from side-to-side around the horizontal axis formed by the horizontal portion 94 of the rod 90 as shown in FIG. 3B. Since its center of gravity is below support rod 90, the replica 10 tends to return to center from any tilted position and, although it is possible, the replica 10 is unlikely to completely overturn. The upward cant of the body 12 and wing members 14, combined with the swinging motion and the side-to-side rocking motion, creates a convincing imitation of a bird in flight.
FIG. 4 illustrates a plurality of flying bird replicas 10 of the type discussed above arranged in the classic V-shaped flying pattern of a group of waterfowl.
Given that wind may not always be available, it is contemplated that in another embodiment, the bird replica 10 may comprise a battery-operated motor operatively connected to support rod 90 that rocks the body 12 from side-to-side regardless of wind conditions.
While certain embodiments of a flying bird replica have been described and illustrated, it will be recognized and appreciated by those skilled in the art that modifications thereof are within the spirit and scope of the invention. The following claims are intended to cover all such modifications.
