Abstract
A vehicle immobiliser has a metal case 5 with security lock 1 which incorporates two anti tamper devices 2 and 6 which isolate the control switches i.e for fuel and electrics from any attempt to operate without use of the correct key. If the lock barrel 1 is forced it cams upwardly on the fixed block 2 shearing the studs 1A, spring 4 disengages the drive to switches 7 and a security plate 6 blocks access thereto. <IMAGE>
Description
VEHICLE INMOBILISER This invention relates to a vehicle fuel and
electrical isolation system.
Isolation systems are common form of a vehicle
security used to immobilise either the fuel or
the electrical systems of the engine by a
standard key switch system.
Normal isolation systems are overridable by
applied force to the key switch system.
According to the present invention there is
provided a dual level anti-tamper system to
isolate the controls from the key switch in
the event of attempted forced operation.
A specific embodiment of the invention will
now be described by way of example with
reference to the accompanying drawing in which :
Figure 1 shows in perspective the immobiliser unit
Figure 2 shows detail of the lower security plate
open and closed.
Referring to the drawing the immobiliser
comprises a solid metal outer case 5,
a security lock 1, a fixed security collar 2,
an operating shaft 3, a spring 4,
security plate 6, isolation units 7.
Any attempt to force lock Fig. 1 will cause fixing bolts fig. 1A to shear by upward force applied by
contour of security collar Fig 2. this will cause
spring loaded shaft Fig 3 to disengage from isolating units Fig 7 allowing security plate Fig 6
to close access to isolation units Fig 7.
Claims (1)
1/ A vehicle isolation system comprising of a
solid metal case incorporating a security
lock and remote isolation units 2/ A vehicle isolation systems as claimed in
1 where-in the security lock is lifted upwards
when forced.
3/ A vehicle isolation system as claimed in
claim 1 or claim 2 where-in the operating
shaft, shaft is lifted clear of isolation
units by spring pressure.
4/ A vehicle isolation system as claimed in
claim 1 or claim 2 or claim 3 where-in the
security-plate isolates the operating shaft
from the isolation units.
5/ A vehicle isolation system substantially
as described herein with reference to
Figure 1-3 of the accompanying drawing.
