Abstract

A bonnet lock immobiliser comprises a release cable 1 which is cut and the two ends inserted into the connectors 2 and secured. Electromagnets 3A,3B move a swinging arm between a position in which the connectors 2 engage to operate the cable and a position in which the connectors are not engaged, so that the bonnet lock cannot be released.

Description

BONNET LOCK IMMOBILISER This invention relates to a bonnet lock immobiliser.
l he bonnet of a motor vehicle is released by the means of a handle inside the vehicle, which pulls a cable and releases the bonnet from the bonnet lock Even when a vehicle is fitted with an alarm and engine immobiliser it is easy for a potential thief to enter the vehicle, release tlie bonnet, disarm the alarm and engine immobiliser and take tiie veIide.
Tllix iiivention when fitted to the bonnet release cable, will prevent the release of the bonnet from inside the vehide. This invention can be used in conjunction with an engine immobiliser and alarm system, or on its own if an essential part of the engine is removed : eg rotar arm or high tension lead, or it can incorperate an alarm and immobiliser.
Figure 1 Shows the device in the OFF position when magnet 3a has been activated and has held the swinging arm 4 with the connectors 2 together.
Figure 2 Shows the device in the ON position when magnet 3b has been activated and has held the swinging arm 4 with the connectors 2 apart. (springs and cables not shown for clarity but as in figure 1.) Figure 3 Is an end view of the swinging arm 4 showing one of the methods of how the connectors 2 are held in place but are allowed to move backwards and forwards.
Figure 4 Shows one of the alternative designs for the way the connectors 2 interlock.
(Figure 1 & 2 show an elevated open view ) The bonnet lock immobiliser is mounted in a suitable position in the engine compartment by means provided (not shown) where the bonnet lock release cable is situated. The release cable 1 is then cut and the two ends are inserted into the connectors 2 and secured by grub screws, nipples or similar means (not shown). When the connectors 2 are together in the OFF position the bonnet can be released in the normal way by operating the handle. When the connectors are apart in the ON position, the bonnet cannot be released by the handle. The connectors are put into the OFF and ON position by remote controlled electrical circuit which operates the electromagnets 3a\3b by giving the relevant magnet a short supply of electricity from the vehicle battery which pulls the swinging arm 4 into position and is held there by the residual holding force of the magnet 3a and cannot move from this position until the other magnet 3b is operated by the same procedure. The ON position magnet 3b is set at a desired angle required to open the connectors 2 enough so that when the handle is pulled the connectors 2 pass each other and do not release the bonnet lock. The springs 5 (optional at this stage) are there to help move the swinging arm 4 against the residual holding force of the magnet 3alb holding the swinging arm 4 to the other magnet 3a\b. The return springs 6 keep the connectors 2 in the desired position. The swinging arm 4 incorperates a metal armature 7 for the magnets 3a\b to attract and a pin 8 for the arm to swing on.

Claims (4)

Claims
1 A lock mechanism for a vehicle having a pivoting arm activated betweetl a first dosed position and a second open position by means of an clcctromagnetic arrangement or by an electric motor operating worm antl gear or rack and pinion components or similar.
2 A lock as claimed in claim 1 adapted for use on a bonnet.
3 A lock as claimed in any preceding claim adapted to be mounted ott a release cable of a vehicle.
4 A lock substantially as herein before described with reference to and as illustrated in the accompanying drawings.
It will be appreciated that although the lock has been described as bonnet lock the invention is not restricted to this, for example the lock may be used on a boot or the like, or any device operated by a cable.
