Motion decoy with biaxial wing beat
First Claim
Patent Images
1. A waterfowl motion decoy, comprising:
- a hollow body shaped in the form of a waterfowl;
at least one wing member shaped in the form of a waterfowl wing, the at least one wing member including a first wing panel and a second wing panel and at least one spring connected to a first edge of the first wing panel and a first edge of the second wing panel, the at least one spring being configured to flex enabling the first wing panel to move with respect to the second wing panel;
an actuator mounted within the body having a drive shaft rotatable about a drive axis;
a swivel joint pivotally coupled to the body so as to pivot about a pivot axis; and
a linkage assembly coupled to the drive shaft and the at least one wing member;
wherein rotation of the drive shaft about the drive axis simultaneously causes the linkage assembly to pivot the swivel joint about the pivot axis and rotate the at least one wing member about a rotation axis formed along a length of the at least one wing member, wherein the rotation axis pivots about the pivot axis along with the swivel joint.

Abstract
A motion decoy having a body and wings in the form of a waterfowl provides a realistic biaxial wing beat motion. The wing beat motion simultaneously includes a flapping action and a rotation action. The flapping action can sweep through an obtuse angle, while at the same time the rotating action that changes the angle of incidence of the wings at different angular positions. The compound biaxial wing beat motion better replicates the motion of live waterfowl, especially during the “lighting” phase of flight.

17. A waterfowl motion decoy, comprising:
-
a hollow body shaped in the form of a waterfowl; a first wing member shaped in the form of a first waterfowl wing and including a first wing shaft, the first wing member including a first wing panel and a second wing panel and a first spring coupling the first wing panel to the second wing panel, the first spring being configured to flex enabling the first wing panel to move with respect to the second wing panel; a second wing member shaped in the form of a second waterfowl wing and including a second wing shaft, the second wing member including a third wing panel and a fourth wing panel and a second spring coupling the third wing panel to the fourth wing panel, the second spring being configured to flex enabling the third wing panel to move with respect to the fourth wing panel; an actuator mounted within the body having a drive shaft rotatable about a drive axis; a first swivel joint pivotally coupled to the body so as to pivot about a first axis; a second swivel joint pivotally coupled to the body so as to pivot about a second axis; a first linkage assembly coupled between the drive shaft and the first wing member; and a second linkage assembly coupled between the drive shaft and the second wing member; wherein rotation of the drive shaft about the drive axis simultaneously causes; the first wing member to rotate about the first axis, the second wing member to rotate about the second axis, the first wing member to rotate about a third axis formed along a length of the first wing shaft, and the second wing member to rotate about a fourth axis formed along a length of the second wing shaft.
