REMOTE CONTROL TEARGAS DISPENSER FOR VEHICLES

-

The purpose of the remote control teargas dispenser fitted to the vehicles, is to stop hijack, smash and grab or any other criminal activities around the vehicle. The dispenser is fitted to spray the teargas in the direction of the criminal, making a teargas barrier between the attacker and the vehicle. The teargas discharge can be activated while in the vehicle or from a short distance away.

The dispenser is mounted on the vehicle to spray towards the doors which is the most probable point of entry. There may be a number of dispensers which can be individual­ly activated.

The dispenser (see sketch – battery and receiver not shown) could be mounted in the following places in/on a vehicle; 1. Mounted to roof rails with nozzle pointing to the doors. 2. Mounted under the vehicle spraying upwards. 3. From the wheel arches. 4. Mounted in the external mirrors. 5. From the engine bay a flexible tube could be secured to spray from between the bonnet and the body in the corners near the external mirrors. The spray would then be directed to the attacker at any of the front doors. 6. Spraying from the opening between the door and body with the dispenser inside the vehicle. 7. Dispenser mounted in the boot, spraying from between the boot lid and the body, in a forward direction to cover the back doors.

A teargas dispenser could be mounted inside the vehicle capsule, to be activated remotely, to stop criminals driving off with the vehicle.

The operation of the dispenser: 1. The remote control signal activates a small high torque DC electric motor. 2. The motor turns a M3 screw threaded bar in an M3 nut which is fixed to the dispenser housing. 3. The rotation of the motor pushes the teargas canister nozzle against the opposite side of the dispenser housing. 4. The nozzle is depressed opening the valve to spray a burst or flooding the area at the doors with tear gas, before any harm could come to the occupants and the vehicle.

The occupants are safe in the vehicle while no air from outside is drawn inside the vehicle capsule. JD CRAWFORD STILBAAI
