Remote controlled decoy

A remotely controlled floating decoy, comprising:

• a buoyant body resembling a game bird;
• a receiver disposed within said buoyant body, said receiver being responsive to commands from a transmitter and providing electrical control signals in response to said commands;
• a propulsive device coupled to said buoyant body and electrically coupled to said receiver, said propulsive device being responsive to said electrical control signals and including:
• an electric motor,
• a shaft having a first end mechanically coupled to said electric motor and extending from said electric motor rearward, said shaft rotating in response to rotation of said electric motor, and
• a propeller mechanically coupled to a distal end of said shaft, said propeller rotating and providing propulsion to said remotely controlled floating decoy in response to said rotation of said electric motor;
• a rudder coupled to a rear end of said buoyant, body and responsive to said electrical control signals, said propulsive device and said rudder cooperating to provide directed locomotion for said buoyant body in response to commands transmitted from said transmitter;
• a brush guard attached to a rear end of the remotely controlled floating decoy, said brush guard comprising a first series of stiff bristles extending from the rear end along a direction substantially parallel to said shaft and spaced apart therefrom, a second series of stiff bristles substantially orthogonal to said first series of stiff bristles, said first series of stiff bristles and said second series of stiff bristles forming a mesh substantially surrounding said propeller, said first series of stiff bristles and said second series of stiff bristles comprise wire bristles forming a closed basket substantially surrounding said propeller and said rudder, said closed basket being readily detachable from said buoyant body;
• an anchor comprising a spool coupled via a cable to a weight;
• an anchor motor coupled to said spool, said anchor motor providing first rotation in a first rotational direction in response to a first electrical control signal "DROP ANCHOR" from said receiver and providing second rotation in a second rotational direction counter-rotational to said first rotational direction in response to a second electrical control signal "RAISE ANCHOR" from said receiver;
• and
• an anchor servomechanism coupled to said anchor motor and to said receiver, said anchor servomechanism, for providing said first and second electrical control signals in response to said electrical control signals from said receiver.

• a propulsive device coupled to said buoyant body and electrically coupled to said receiver, said propulsive device being responsive to said electrical control signals;
• a rudder coupled to a rear end of said buoyant body and responsive to said electrical control signals, said propulsive device and said rudder cooperating to provide directed locomotion for said buoyant body in response to commands transmitted from said transmitter;
• a lower mandible disposed at a front end of said buoyant body, said lower mandible having serrations disposed on an upper surface thereof, said lower mandible hingedly attached to said buoyant body;
• a first mechanical linkage having a first end coupled to said lower mandible;
• and
• a servomechanism electrically coupled to said receiver and mechanically coupled to a second end of said first mechanical linkage, said servomechanism being responsive to said electrical control signals and causing said lower mandible to raise in response to first electrical control signals "CLAMP" from said receiver and causing said lower mandible to lower in response to second electrical control signals "DO NOT CLAMP" from said receiver.

A remotely controlled floating decoy, comprising:

• a radio transmitter adapted remote control, said radio transmitter providing commands comprising radio signals in response to manual requests entered on a control panel thereof;
• a buoyant body resembling a duck, said buoyant body including a weighted keel suspended beneath said buoyant body, said weighted keep only partly counteracting buoyancy of said buoyant body, said weighted keel including a first opening disposed at a front end of said weighted keel and adapted to accept a towing attachment;
• a radio receiver disposed within said buoyant body, said radio receiver being responsive to said commands from said radio transmitter and providing electrical control signals to a plurality of servomechanisms in response to said commands;
• a propulsive device coupled to said buoyant body and to said radio receiver, said propulsive device including a first servomechanism of said plurality of servomechanisms, said first servomechanism being responsive to said electrical control signals, said propulsive device including:
• an electrical motor,
• a switch, said switch comprising a normally open, double pole, double throw switch, said switch mechanically coupled to said first servomechanism such that said first servomechanism places said switch in either closed position or an open position in response to commands from said radio receiver, said switch electrically coupled to said electric motor and to a battery holder such that polarities of terminals from said battery holder in a first thrown position of said switch are reversed with respect to said electric motor with respect to a second thrown position of said switch, said electric motor rotating in a first direction when said switch is placed in said first thrown position and rotating in a second direction counter rotational to said first direction when said switch is placed in said second thrown position,
• an elongate shaft having a first end mechanically coupled to said electric motor and extending from said electric motor rearward, said elongate shaft rotating in response to rotation of said electric motor, and
• a rudder coupled to a rear end of said buoyant body and mechanically coupled to a second servomechanism of said plurality of servomechanisms, said second servomechanism electrically coupled to said radio receiver and responsive to said electrical control signals, said propulsive device, said first servomechanism, said rudder and said second servomechanism cooperating to provide directed locomotion for said buoyant body in response to said commands transmitted from said radio transmitter;
• an anchor comprising a spool coupled via a cable to a weight;
• an anchor motor mechanically coupled to said spool, said anchor motor providing first rotation in a first rotational direction in response to a first electrical control signal "DROP ANCHOR" from said radio receiver and providing second rotation in a second rotational direction counterrotational to said first rotational direction in response to a second electrical control signal "RAISE ANCHOR" from said radio receiver;
• and
• an anchor servomechanism coupled to said anchor motor and to said radio receiver, said anchor servomechanism for providing said first and second electrical control signals in response to said electrical control signals from said radio receiver.
