Kinematically Accurate Goose Decoy

摘要

A game bird decoy provides for more natural kinematics by providing a smoothly articulating neck, an automatic orientation of the neck with respect to body tipping and improved dual-mode wing activation in which the wings may lift or lift and extend as a function of body angle.

主权项

1. A game bird decoy comprising:
a body element having a flexible neck element extending therefrom, the body element and flexible neck element sized and decorated to resemble a bird; wherein the flexible neck element includes a stack of inter-engaging neck segments extending along a neck axis, each of said neck segments pivotally attached to an adjacent neck segment of said stack of neck segments to provide a limited pivoting with respect to the adjacent neck segment to curve the neck axis; at least one tension band attached to an upper neck segment of the stack of neck segments and downwardly extending along the stack of neck segments to follow any curvature of the neck axis; a-first DC electric motor receiving the tension band to apply tension to the tension band to controllably curve the flexible neck element; and an electronic, computer executing a stored program to control the DC electric motor to provide for controlled bending of the neck axis; a second DC electric motor communicating with the neck and operating with the first DC electric motor to provide forward and left and right controlled curvature of the flexible neck element; further including a head element rotatably attached at a distal end of the neck element to rotate about the neck axis as actuated by a third DC motor said thud DC motor is different from the DC motor; wherein the head element is mounted to the neck element to allow bobbing of the head element with respect to the neck axis about an axis perpendicular to the neck axis as actuated by a fourth DC motor said for DC motor is different from the DC motor, the second DC motor and the third DC motor.
