Abstract
A drive system for animating a hunting decoy is designed to fit within the decoy's hollow body and provide movement to appendages, such as wings, on the decoy. The drive system comprises a battery-operated DC motor for imparting reciprocal movement of mounting pegs on which the appendages are affixed. The oscillating, reciprocating motion is provided by an eccentric that is coupled through flexible leaf spring links to the periphery of first and second wheels that are journaled for rotation on parallel axes. The leaf spring linkages function to counter-balance the weight of the appendages, reducing current drain on the motor.
Claims11
An apparatus for animating a hunting decoy, the decoy including a hollow body and an appendage adapted to be moved relative to the hollow body, comprising:
- (a) a mounting block affixed to a portion of the hollow body and projecting inwardly into an interior of the hollow body;
- (b) an electric motor drive means attached to said mounting block, the motor drive means having an output shaft supporting an eccentrically disposed drive shaft, the drive shaft journaled for rotation in a connector block;
- (c) a first wheel journaled for rotation on the mounting block;
- (d) a flexible link member joining the connector block to a peripheral surface of said first wheel for reciprocal rotation of said first wheel through a predetermined arc;
- and
- (e) means for coupling the appendage to the first wheel.
