Abstract

A motor vehicle interdiction device with an elastic bladder inserted by hand or fired as an infrared seeking missile into an automobile exhaust pipe and inflated with a compressed gas cartridge.

Claims

1. A motor vehicle interdiction device comprising:

(A) an elastic bladder of a size and shape adapted to be inserted into an exhaust pipe opening of a motor vehicle,

(B) a compressed gas cartridge operably connected to the elastic bladder, the cartridge, when opened, being capable of causing the bladder to expand to a size greater than the opening of the exhaust pipe,

(C) a piercer capable of piercing the compressed gas cartridge connected to the gas cartridge adapted to open the gas cartridge when actuated allowing the compressed gas to enter the bladder, and

(D) a lever operably connected to the piercer adapted to actuate the piercer when the bladder is inserted into the exhaust pipe opening of the motor vehicle.

3. The device of claim 1 further comprising an arm extension member comprising a proximal end operably connected to the lever, a distal end adapted to be gripped by person, and a length adapted to allow the person to insert the bladder into the exhaust pipe opening without having to bend down behind the vehicle.

4. The device of claim 1 further comprising:

(A) a cylindrical tubular body comprising an aero dynamic head, a frangible forward section and retractable fins extending radially outwardly from a rearward section of the body,

(B) an infrared sensor in the head adapted to locate an exhaust pipe opening on an motor vehicle within a defined conical space fanning out in a direction the projectile is traveling, and

(C) guidance means in the rearward section adapted to adjust the path of the flight of the device to direct the flight of the projectile to the exhaust pipe opening,

(D) wherein the elastic bladder is located in the frangible forward section of the body, and the lever is adapted to actuate the piercer to release the gas upon the projectile entering the exhaust pipe of the motor vehicle.

5. The device of claim 4 wherein the wherein the gas cartridge is adapted to be punctured to release the gas and the piercer is adapted to puncture the cartridge when actuated by the device coming to an abrupt halt.

6. The device of claim 5 wherein the lever is weight loaded and adapted to release a spring loaded pointed piercer rod to puncture the gas cartridge when the weight is thrown forward as the device is halted in the exhaust pipe of the motor vehicle.

2. (canceled)

7. A motor vehicle interdiction projectile device comprising:

(A) a cylindrical tubular body comprising an aero dynamic head, a frangible forward section and retractable fins extending radially outwardly from a rearward section of the body,

(B) an infrared sensor in the head adapted to locate an exhaust pipe opening on an motor vehicle within a defined conical space fanning out in a direction the projectile in traveling,

(C) guidance means in the rearward section adapted to adjust the path of the flight of the device to direct the flight of the projectile to the exhaust pipe opening,

(D) an elastic bladder in the frangible forward section of the body, the bladder operably connected to a compressed gas cartridge adapted to inflate the bladder to a size greater than the exhaust pipe opening of the motor vehicle upon gas being released from the cartridge, and

(E) a piercer attached to the compressed gas cartridge adapted to release the gas upon the projectile device entering the exhaust pipe opening of the motor vehicle.

8. The device of claim 7 wherein the wherein the gas cartridge is adapted to be punctured to release the gas and the piercer is adapted to puncture the cartridge when actuated by the device coming to an abrupt halt.

9. The device of claim 7 wherein the device further comprises a weight loaded lever adapted to release the piercer, which comprises a spring loaded pointed rod adapted to puncture the gas cartridge when the weight is thrown forward as the device is halted in the exhaust pipe of the motor vehicle.

10. A method of motor vehicle interdiction comprising:

(A) providing a device comprising;

a. an elastic bladder of a size and shape adapted to be inserted into an exhaust pipe opening of a motor vehicle,

b. a compressed gas cartridge operably connected to the elastic bladder, the cartridge, when opened, being capable of causing the bladder to expand to a size greater than the opening of the exhaust pipe,

c. a piercer operably connected to the gas cartridge adapted to open the gas cartridge when actuated allowing the compressed gas to enter the bladder

d. a lever operably connected to the piercer and adapted to actuate the piercer when the bladder is inserted into the exhaust pipe opening of the motor vehicle.

(B) inserting the device into an exposed end of a motor vehicle exhaust pipe and actuating the lever causing the piercer to open the gas cartridge inflating the bladder to block flow out of the exhaust pipe and prevent operation of the motor vehicle.

12. The method of claim 10 wherein the device further comprises an arm extension member comprising a proximal end operably connected to the lever, a distal end adapted to be gripped by person, and a length adapted to allow the person to insert the bladder into the exhaust pipe opening without having to bend down behind the vehicle.

11. (canceled)

13. A method of motor vehicle interdiction comprising:

(A) providing a gun comprising a tubular barrel, and propellant to propel objects out of the barrel,

(B) inserting a projectile device into the tubular barrel, the device comprising;

(i) a cylindrical tubular body comprising an aero dynamic head, a frangible forward section and retractable fins extending radially outwardly from a rearward section of the body,

(ii) an infrared sensor in the head adapted to locate an exhaust pipe opening on an motor vehicle within a defined conical space fanning out in a direction the projectile is traveling,

(iii) guidance means in the rearward section adapted to adjust the path of the flight of the device to direct the flight of the projectile to the exhaust pipe opening,

(iv) an elastic bladder in the frangible forward section of the body, the bladder operably connected to a compressed gas cartridge, when opened, being capable of causing the bladder to expand to a size greater than the exhaust pipe opening on the motor vehicle, and

(v) a piercer attached to the compressed gas cartridge adapted to release the gas upon the projectile device entering the exhaust pipe opening of the motor vehicle, and

(C) aiming the gun at an exposed end of a motor vehicle exhaust pipe and causing the propellant to propel the projectile device into the exhaust pipe to block flow out of the exhaust pipe and stop the motor vehicle from operating.
