Abstract

This Anti Theft Device allows you on leaving your vehicle to simply depress the brake pedal or lever, and then operate a valve in the braking system to leave the vehicle with all the road wheel brakes on. The valve may be operated by a key or by a remote controlled electronic device, and may, when closed, immobilize the engine. An audible and visual alarm may be operated, when the valve is closed and the driver attempts to start its vehicle engine by turning the ignition key.

Description

VEHICLE ANTI THEFT DEVICE The braking system of most vehicles operate on the Hydraulic System. Virtually all motor cars, light commercials and motorcycles have this system as standard. Some systems are power assisted in various ways that multiply the pressure applied to the pedal or lever. Some systems are more complexed than others, having Anti Skid and Duel Circuit Systems. They all rely on oil under pressure flowing in one direction to put the brakes on, and when the pressure is released to flow back again allowing the brakes to be released.
This invention is to incorporate a valve, as yet unspecified in design, but probably of a simple gate valve type, into the Hydraulic braking system of a Motorcar, Light Commercial, Motorcycle or any othe Hydraulically braked vehicle. The valve would need to be of a suitable type, capable of accommodating and keeping separate the Duel Circuit Systems, with a view to arresting the flow of oil in each system.
A good quality security system, probably of a barrel lock and key, or maybe Remote Controlled Electronic Device, to be attached to the valve in such a manor asto allow the key to operate the valve and the complete component be tamperproof.
This component, hence forth called the Valve Component, then to be mounted in a suitable position accessable by the driver, probably in or under the dashboard of a car, or any appropriate position on a Motorcycle. The Hydraulic system interrupted at a point after the power assistance if fitted, and in, or preferably after the master cylinder in either case. A most logical area would be to interupt the rigid brake pipe system, divert the pipes from the master cylinder to the valve of the valve component, then from the valve to their original destination.
With the valve in the open position it would be possible to press the brake pedal or lever, utilizing the benefit of any power assistance provided, to put the road wheel brakes fully on. By holding the brakes on whilst turning the key(if that is the chosen security system) in the valve component and closing the valve,thus preventing the return of fluid or pressure, it is now possible to release the brake pedal or lever, and the road wheel brakes will remain on.
As a saftey precaution,when the valve is in the closed position and the vehicle ignition key turned, suitable warning of the closed valve be made to the driver audibly and visually via a series of electrical contacts or switches incorporated in the valve component. Also the engine be made not to start until the valve component key has opened the valve.

Claims (4)

1 A Vehicle Anti Theft Device comprising of a security key operated valve incorporated in the vehicles hydraulic system.
2 A Vehicle Anti Theft Device as in Claim 1 wherein the valve may be operated by a remote controlled electronic device instead of a mechanical key, if deamed more appropriate on final manufacture.
3 A Vehicle Anti Theft Device as in Claim 1 and Claim 2 wherein the valve component to incorporate an electrical contact or switch or series of contacts or switches for the purpose of informing the driver that the valve is in operation. Also to immobilize the engine until the proper key is used to open the valve.
4 A Vehicle Anti Theft Device as in Claim 1 and Claim 2 and Claim 3 wherein the valve to be capable of closing off the Duel Circuit Systems simultaneiously. Or by design alteration independantly if required.
