Abstract

A vehicle security device has a body 11 which has an on/off valve 4 which is used to allow or arrest the flow of fluid and a one way valve 2, 3 to allow fluid to travel only from inlet 5 to outlet 6 when valve 4 has arrested the fluid flow as shown. The valve 4 can be switched to its on or off position by a key system 13, a motor (14, Fig 5), or on/off switch (15, Fig 6). A cover 12 is also provided. <IMAGE>

Description

VEHICLE ANTI-THEFT DEVICE The invention described in the following passages is a vehicle anti-theft device. It may not be common knowledge but in the UK alone a vehicle is stolen every 58 seconds and would be an astronomical number world wide,this is at the 1993 level.
There are several devices on the market at present to disable vehicles electronically mainly but these can be by-passed and are often ignored when they go off because they are so common and pre to high winds setting them off, and people knocking them accidently.
There are some other devices which hold brake/accelorator/clutch to the steering wheel and another which holds hand brake to gear stick but not all are suitable.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawings -which: Fig 1 shows the device in normal working condition.
Fig 2 shows the device in locked condition.
Fig 3 shows the device locked and at rest.
Fig 4 shows the device with key lock Fig 5 shows the device with motor lock.
Fig 6 shows the device with handle lock.
This invention works in the following way:- There are two holes drilled in a single block in parallel (7 & 9) on the longest side and two further holes drilled at 90r angles to the first two (8 & 10) and set as shown in drawings. In one of the longest holes an on/off vavle (4) is inserted and in the second of the longest holes drilled as shown a ball (2) and spring (3) are placed in a funnel type drilling (9). The two holes drilled at 90" to these are for the cross flow of fluid (8 & 10).
The anti-theft device works as follows, when it has been correctly fitted to the clutch system there is no hinderance to the fluid flow as long as the valve (4) is open (see Fig 1). when the on/off valve (4) is switched through 90 to the on position the fluid flow is hindered and can only flow through the ball(2) and spring(3)(see Fig 2)(in effect a one way valve) this will allow the fluid to flow through but not back. The result is that the clutch is pernanently disengaged from the fly wheel until such time as the on/off valve (4) is returned through 9a back to the open position (see Fig 1). The result is that when the device is swtiched to the off position the vehicle cannot be driven by its own engine. The above system cannot be used for vehicles with automatic transmission to the clutch system.
When the device has been correctly fitted into the braking system it works as follows:- the brake fluid will flow unhindered through the on/off valve (4) (see Fig 1). When the on/off valve (4) has been switched through 9Cw to the on position the fluid flow will be hindered and can only flow through the one way valve (2 & 3)(see Fig 2) and therefore should the brakes be applied the brakes will remain on and the vehicle will be immobolised, as with the clutch the brakes can only be released by turning the on/off valve (4) through 90% to the on position to allow thefluid to flow normally.
when used on the braking system the device can be fitted to all types of vehicles with a fluid braking system.
The device may be made up of pipes and valves but for ease of fitting and to reduce anyperson tampering with it is preferable to make it in a single block, drilled to suit.
The valve (4) could be of the butterfly type, push button type, ball valve type, or of the diaphragm type. A ball valve is the better of the types listed for aid of better sealing.
The one way valve (2 & 3) could compromise of a gravity drop valve, ball and spring valve, or other types of non return valve but a ball and spring is prefered due to a better seal and the action of the spring keeping the ball tight in its position.
The device needs to be fitted in such away as the flow of fluid from the pumping source travels in the inlet (5) and out the outlet (6) towards either the clutch or brake cylinders this will facilitate the clutch to be disengaged or the brakes remaining on. fitting in the reverse direction will result in the device not functioning correctly.
This device will also aid in the bleeding of the system that it has been attached to.

Claims (3)

1. A vehicle security device comprising of a solid block of suitable material worked on to enable a single one way valve and a single on/off valve to be set in parallel in the block with the cross flow ports. A means of switching the on/off valve by use of a key, motor or handle. A cover suitable for holding the key, motor or handle in a working position. With two holes threaded to take the suitable inlet and outlet pipes.
2. A vehicle security device as claimed in claim 1 wherein a on/off valve is incorporated to arrest or allow flow of suitable fluid when desired.
3. A vehicle security device substantially as described here in with reference to figures 1 - 6 of the accompanying drawings.
3. A vehicle security device as claimed in claim 1 wherein a one way valve is incorporated to allow flow of a suitable fluid to move in one direction only when desired.
4. A vehicle security device as claimed in all preceding claims wherein the body has at least one or more means of mounting to a desired vehicle.
