Abstract
A projectile launcher having a magnet based driver motor. The driver motor is constructed of a coil winding suspended within a magnetic field formed by the combination of a front plate, a magnet and a pole piece attached to a back plate. An electrical controller is electrically coupled to the driver motor and allows for remote operation of the launcher. The coil may include a diaphragm capable of producing sounds wherein electrical current applied to the coil winding causes the coil to vibrate according to an audio frequency to make a desired sound, or travel a predetermined distance so as to cause an ejection of a projectile placed over the coil.
Claims17
A electro-magnetic projectile launching device comprising a cylindrical pipe having an inner surface with an upper open end and a lower end;
- a driver magnet coupled to said lower end;
- a former and shuttle constructed and arranged to fit between at least a portion of said driver magnet and movable along a length of said cylindrical pipe;
- a control unit for directing an electrical charge to said former;
- and
- a rechargeable power source coupled to said control unit;
- wherein an object placed within said upper open end of said cylindrical pipe is launched a distance in response to the electrical charge directed to said former.
A K-9 electro-magnetic projectile launching device comprising:
- a housing having a substantially flat top surface with side walls depending therefrom forming a cavity therebetween;
- a receptacle for holding a scented object positioned within said housing;
- a launching assembly mounted within said housing, said launching assembly comprising a cylindrical pipe having an inner surface with an upper open end extending through said flat top surface of said housing and a lower end placed within the cavity of said housing, a driver magnet coupled to said lower end;
- a former constructed and arranged to fit between at least a portion of said driver magnet and movable along a length of said cylindrical pipe;
- a control unit for directing an electrical charge to said former;
- and a receiver coupled to said control unit available for receipt of a wireless actuation command from a remotely located RF transmitter for operation thereof;
- and
- a rechargeable power source coupled to said control unit;
- wherein upon a K-9 detecting a scented object placed in the receptacle, said control unit is engaged to launch an object placed within said cylindrical pipe whereby the launched object operates as a reward.
