Kinematically accurate game bird 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 restoring spring urging the neck segments into a resting alignment, wherein the resting alignment defines the neck axis; at least one tension band attached to an of said stack of neck segments upper neck segment and downwardly extending along the stack of neck segments to follow any curvature of the neck axis; a servo-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 servo-motor to provide for controlled bending of the neck axis; wherein the at least one tension band further includes at least three tension bands and the servomotor includes at least two servomotors and wherein the at least three tension bands attached to the at least two servo-motors to provide for forward and left and right controlled curvature of the flexible neck element; wherein the restoring spring is a central spring element passing upward through the inter-engaging segments and wherein the resting alignment is a substantially straight alignment of the inter-engaging neck segments; further including a head element rotatable attached at a distal end of the neck element to rotate about the neck axis as actuated by second servo-motor said second servo-motor is different from the servo-motor after “a second servo-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 third servo-motor said third servo-motor is different the servo-motor and the second servo-motor.
