BACKGROUND 
     1. Field of Invention 
     This invention relates to bird figures for use as lawn ornaments and the like and is particularly directed to bird figures having movable wings which are wind-actuated to provide somewhat life-like action. 
     2. Prior Art 
     It has long been popular to provide figures of birds and other animals as lawn ornaments and the like. Moreover, it is common to provide lawn ornaments in figures, such as windmills, birds, gnomes, etc. having vanes, wings or arms which are wind-actuated to rotate about an axis generally perpendicular to the longitudinal axis of the vane, wing or arm to create motions which revolve in large circular patterns to provide animation for the figures. It is also popular to provide bird figures having wings which flap, due to various mechanisms, to provide animation. However, while such circular revolving and flapping wing motions are satisfactory in providing animation for many birds, especially large birds, such as geese, such motions do not provide appropriate animation simulation for hummingbirds. Because the beat rate of hummingbird wings is too fast for human observation, the wings of real hummingbirds generally appear as a blur and the revolving or flapping motions of prior art lawn figure birds provide inadequate simulations of this motion. A search in the United States Patent Office has revealed the following:

     DETAILED DESCRIPTION OF THE INVENTION 
     In that form of the present invention chosen for purposes of illustration in the drawing, FIG. 1 shows a bird figure, indicated generally at 10, having a body portion 12 suspended by a string 14 or the like, a tail portion 16 mounted on the body portion 12 and a pair of wing structures 18 and 20 which are mounted on opposite ends of a rigid wire 22 and extend substantially perpendicularly to the plane of the body portion 12. The wire 22 passes through a tube 24 mounted in an opening 26 formed in the body portion 12 and projecting substantially perpendicularly to the plane of the body portion 12. The wire 22 is freely rotatable within the tube 24 to allow free rotation of the wing structures 18 and 20 about the longitudinal axes of the wing structures 18 and 20 and perpendicular to the plane of the body portion 12. Preferably, however, spherical beads 27 are mounted on the wire 22 between the wing structures 18 and 20 and the adjacent ends of the tube 24 to facilitate free rotation of the wing structures 18 and 20, as best seen in FIG. 7. 
     The body portion 12 and tail portion 16 are preferably formed of relatively rigid planar material, such as plywood, and the body portion 12 is formed with an elongated slot 28, as best seen in FIG. 3, communicating with one edge of the body portion 12 and serving to frictionally receive the tail portion 16, as seen in FIGS. 1 and 2. The tail portion 16 is preferably formed with a recess 30 in its forward end to frictionally engage the body portion 12 adjacent the inner end of slot 28 to assure proper positioning of the tail portion 16 with respect to the body portion 12. The side profile of the body portion 12 is shaped to represent the head and body shape of a bird, while the vertical profile of the tail portion 16 is shaped to represent the body and tail shape of a bird. As best seen in FIG. 5, wing structure 18 is formed from a relatively star-shaped member composed of relatively rigid material, such as metal, plastic or the like and is formed with a central generally circular hub 32 having three or more blades 34 of generally alate configuration radiating from the hub 32. Each of the blades 34 has a relatively straight leading edge 36 with three tabs 38, 40 and 42 which project forwardly from the leading edge 36 and has a trailing edge 44 which tapers gradually from the relatively pointed outer tip 46 to a relatively wide inner end 48. As seen in FIG. 5, the trailing edge 44 may be serrated or otherwise formed to simulate feathers. Alternatively, if desired, the trailing edge 44 may be smooth and real or simulated feathers may be attached to the surface of the blade 34, as by gluing. To form the wing structure 18, the blades 34 are bent to lie substantially perpendicularly outward from the hub 32 and the tabs 38, 40 and 42 are joined to the corresponding tabs 38, 40 and 42, respectively, of the adjacent blades 34 by suitable means, such as rings 50, 52 and 54. Thus, ring 50 joins the tabs 38 of each of the blades 34, while ring 52 joins the tabs 40 of each of the blades 34 and ring 52 joins tabs 42 of each of the blades 34 to cause the blades 34 to form a generally cylindrical wing structure 18, as best seen in FIG. 6, with hub 32 at the inner end of the wing structure 18 and the tips 46 of the blades 34 at the outer end of the wing structure 18. It should be noted that the leading edges 36 of the blades 34 of wing structure 18 are on the counter-clockwise sides of the blades 34. As best seen in FIG. 7, the hub 32 is formed with a central opening 56 and wire 22 extends through tube 24 in the body portion 12 and passes through the openings 56 and extends axially of the wing structures 18 and 20, passing through the rings 50, 52 and 54 in each of the wing structures 18 and 20 and having retaining means 58 carried at the ends of the wire 22 to rotatably retain the wing structures 18 and 20 on the wire 22. 
     Wing structure 20 will be substantially identical to wing structure 18 except that the leading edges of the blades of wing structure 20 must be on the clockwise sides of the blades. This is necessary because wing structure 18 is mounted to project from the right side of the body portion 12, while wing structure 20 is mounted to project from the left side of body portion 12. Since the wing structures 18 and 20 project from opposite sides of the body portion 12, the wing structures 18 and 20 must be formed with the leading edges on opposite sides of the blades in order to cause the wing structures 18 and 20 to rotate in the same direction. Otherwise the torque developed by wind blowing on the wing structures will cancel each other and will prevent rotation of the wing structures 18 and 20. 
     To assemble the bird figure 10, the tail portion 16 is slid into the slot 28 until recess 30 seats firmly against the body portion 12 and the plane of the tail portion 16 extends generally perpendicularly to the plane of the body portion 12. Tube 24 is then inserted into opening 26 of the body portion and wire 22 is passed through the tube 24. The wing structures 18 and 20 are assembled by passing the wire 22 through openings 56 in the hubs 32 of each of the wing structure 18 and 20 and extends axially of each of the wing structures 18 and 20, through rings 50, 52 and 54 of the wing structures 18 and 20. Finally the retaining means 58 serve to rotatably retain the wing structures 18 and 20 on the wire 22 with the axes of the wing structures extending generally perpendicular to the plane of the body portion 12. As noted above, the leading edges 36 of the blades 34 of wing structure 18 are on the counterclockwise sides of the blades 34, while the leading edges of the blades of wing structure 20 are on the clockwise sides of the blades. Thus, when wind is blowing toward the front of the bird figure 10, it will cause both wing structures 18 and 20 to rotate in the same direction and, because each of the wing structures 18 and 20 is composed of a plurality of blades 34, rotation of the wing structures 18 and 20 will produce a somewhat blurred visual effect which realistically simulates the rapid beating of hummingbird wings. 
     It will be apparent that the specific shapes of the body portion 12, tail portion 16 and wing structures 18 and 20 may be varied substantially as desired. Moreover, the location and shape of the slot 28 of the body portion 12 may be varied widely. In addition, numerous other variations and modifications can, obviously, be made without departing from the spirit of the present invention. Therefore, it should be clearly understood that the forms of the present invention described above and shown in the figures of the accompanying drawing are illustrative only and are not intended to limit the scope of the present invention.
